Pyrolysis of oil sludge first by thermogravimetry/mass spectroscopy (TG/MS) and then in a horizontal quartz reactor with an electrical laboratory furnace under different pyrolysis conditions was carried out. The influence of heating rate from 5 to 20 °Camin-1, final pyrolysis temperature from 400 to 700 °C, various interval holding stage, and catalyst on the products were investigated in detail. The TG/MS results show that pyrolysis reaction of oil sludge starts at a low temperature of about 200 °C, and the maximum evolution rate is observed between the temperatures of 350-500 °C. A higher final pyrolysis temperature, an interval holding stage, and adding catalyst can promote the pyrolysis conversion (in terms of less solid residue production). In all parameters, an interval holding stage for 20 min near the peak temperature of 400 °C can enhance the yield of oil and improve its quality. Three additives used in this work as catalysts do not improve oil product quality markedly in spite of increasing pyrolysis conversion greatly.油泥的裂解首先通过热重/质谱分析（TG / MS），然后在水平石英反应器中具有不同热解条件下的电气实验室炉进行。

车床用于车外圆、端面和镗孔等加工的机床称作车床。
车削很少在其他种类的机床上进行，因为其他机床都不能像车床那样方便地进行车削加工。
由于车床除了用于车外圆还能用于镗孔、车端面、钻孔和铰孔，车床的多功能性可以使工件在一次定位安装中完成多种加工。
这就是在生产中普遍使用各种车床比其他种类的机床都要多的原因。
两千多年前就已经有了车床。
现代车床可以追溯到大约1797年，那时亨利•莫德斯利发明了一种具有把主轴和丝杆的车床。
这种车床可以控制工具的机械进给。
这位聪明的英国人还发明了一种把主轴和丝杆相连接的变速装置，这样就可以切削螺纹。
车床的主要部件：床身、主轴箱组件、尾架组件、拖板组、变速齿轮箱、丝杆和光杆。
床身是车床的基础件。
它通常是由经过充分正火或时效处理的灰铸铁或者球墨铸铁制成，它是一个坚固的刚性框架，所有其他主要部件都安装在床身上。
通常在球墨铸铁制成，它是一个坚固的刚性框架，所有其他主要部件都安装在床身上。
通常在床身上面有内外两组平行的导轨。
一些制造厂生产的四个导轨都采用倒“V”，而另一些制造厂则将倒“V”形导轨和平面导轨结合。
由于其他的部件要安装在导轨上并（或）在导轨上移动，导轨要经过精密加工，以保证其装配精度。
同样地，在操作中应该小心，以避免损伤导轨。
导轨上的任何误差，常常会使整个机床的精度遭到破坏。
大多数现代车床的导轨要进行表面淬火处理。
以减少磨损和擦伤，具有更大的耐磨性。
主轴箱安装在床身一端内导轨的固定位置上。
它提供动力。
使工件在各种速度下旋转。

IntroductionLatvian legislation for forest protection belts Latvian legislation demands that forest protection belts are established around all cities and towns. The concept of protection belts originates from the Soviet Era and is maintained in Latvian legislation despite the radical changes to the political system after regaining indepen-dence in 1991. The legal background for the establish-ment of protection belts is as follows:•Law on Protection Belts (1997, 2002)•Forest Law (2000)•Law on Planning of Territorial Development (1998).Designating a greenbelt around the city of Riga, LatviaJanis DonisLatvian State Forestry Research Institute ‘Silava’, Salaspils, LatviaAbstract: Latvian legislation demands that forest protection belts are established around all cities and towns. The main goal of a protection belt is to provide suitable opportuni-ties for recreation to urban dwellers and to minimise any negative impacts caused by urban areas on the surrounding environment. Legislation states the main principles to be adopted, which include the maximum area of protection belts, their integration in terri-torial development plans and restrictions placed on forest management activities. The largest part of the forest area around Riga is owned by the municipality of Riga, which, as a result, has two competing interests: to satisfy the recreational needs of the inhabitants of Riga, and to maximise the income from its property. In order to compile sufficient background information to solve this problem, the Board of Forests of Riga Municipality initiated the preparation of a proposal for the designation of a new protection belt.The proposal was based on the development and application of a theoretical framework developed during the 1980s. The analysis of the recreational value of the forest (5 class-es of attractiveness) was carried out based on categories of forest type, dominant tree species, dominant age, stand density, distance from urban areas and the presence of at-tractive objects. Information was derived from forest inventory databases, digital forest maps and topographic maps. Additional information was digitised and processed using ArcView GIS 3.2. Local foresters were asked about the recreation factors unique to differ-ent locations, such as the number of visitors and the main recreation activities. From a recreational point of view and taking into account legal restrictions and development plans for the Riga region, it was proposed to create three types of zones in the forest: a protection belt, visually sensitive areas and non-restricted areas.Key words:greenbelt forest, recreational value, GIS, zoningThe Law on Protection Belts states that protection belts around cities (with forests as part of a green zone)have to be established (a) to provide suitable conditions for recreation and the improvement of the health of urban dwellers, and (b) to minimise the negative im-pact of urban areas on the surrounding environment.Urban For.Urban Green.2 (2003):031–0391618-8667/03/02/01-031 $ 15.00/0Address for correspondence:Latvian State Forestry Re-search Institute ‘Silava’, Rı¯gas iela 111, Salaspils, LV-2169,Latvia. E-mail: donis@silava.lv© Urban & Fischer Verlaghttp://www.urbanfischer.de/journals/ufugRegulation nr 263 (19.06.2001) on the ‘Methodology for the establishment of forest protection belts around towns’issued by the Cabinet of Ministers (CM) states: (a) The area of a protection belt depends on the numberof inhabitants in the town: towns with up to 10,000 inhabitants should have a maximum of 100 ha of protection belt, those with between 10,000 and 100,000 inhabitants a maximum of 1,500 ha, and towns with more than 100,000 inhabitants a maxi-mum of 15,000 ha;(b) the borders of protection belts have to be able to beidentifiable on the ground, using features such as roads, ditches, power lines, and so forth;(c) protection belts have to be recorded in the territorialplans of regions adjacent to the town or city; and (d) establishment of protection belts has to be agreedupon by local municipalities.According to law, protection belts should be man-aged using adapted silvicultural measures. Clear-cut-ting, for example, is prohibited in a protection belt to mitigate any negative impacts of the city on the sur-rounding environment. The Forest Law of 2000 and subsequent regulations including the Regulation on Cutting of Trees, and the Regulation on Nature Conser-vation in Forestry define clear-cuts as felled areas larg-er than 0.1 ha where the basal area is reduced below a critical level in one year. These regulations also state the permitted intensity and periodicity of selective cut-ting (30–50%, at least 5 years between entries).The third element of the legal framework relevant for protection belts in Latvia is the Law on Planning of Territorial Development (1998). It defines:(a) Principles and responsibilities of the different or-ganisations involved;(b) the contents of territorial plans;(c) the procedures for public hearing; and(d) the procedures for the acceptance of plans.The law also states that protection belts around towns have to be designated in territorial plans. Thus, the legislation gives very detailed descriptions of the restrictions to maximum area, activities and guidelines for delineation and so forth, while there are no ‘rules’for the choice of what areas are to be included in pro-tection belts. It is up to territorial planners to propose what areas to include and for negotiation among mu-nicipalities to approve the selection.Protection belt for the city of RigaRiga and the Riga region are situated in the Coastal Lowland of Latvia within the Gulf of Riga. The main landform types are the Baltic Ice Lake plain, the Litto-rina Sea plain and the Limnoglacial plain and bog plain. The total area of the administrative area of the City of Riga covers 307.2 km2, and that of the Riga re-gion 3,059 km2. In 2000 the city of Riga had 815,000 inhabitants, while an additional 145,000 people resided in the greater Riga region. During the last decade the number of inhabitants in Riga decreased by 10.5%and in Riga region by 5.3%. In the mid-1990s the main types of industry in Riga were food processing, timber and wood processing, metal fabricating and engineer-ing, while in the region agriculture and forestry, wood processing, pharmaceuticals, and the power industry were the main activities. Due to reduced industrial ac-tivities today, the main sources of pollution in Riga re-gion are road transport and households.The greater part of the Riga region is covered by for-est, i.e. 1,642 km2or 53%. About 26% of the land is used for agriculture, 4% is covered by bogs, and 4% by water. The Riga region also has a coastal dune zone of some 30 km along the Gulf of Riga. The main tree species to be found in the Riga region are Scots pine (Pinus sylvestris L.),birch (Betula spp.) and Norway spruce (Picea abies (L.) Karsten) (see Table 1). In the administrative area of the city of Riga, 57 km2 or about 19% of the land area is forest. Scots pine is the domi-nant species, covering approx. 46.9 km2(i.e. 88% of the total forest area).According to the legislation described before, a pro-tection belt around Riga city, with a maximum size of 15,000 ha, could be designated. Moreover, any propos-al has to be agreed upon among 24 local municipalities. The Riga region is divided into 24 administrative units: 7 towns and 17 pagasts or ‘parishes’.Riga municipality currently owns more than 55,600 ha of forests. Most are situated in the vicinity of Riga. Four forest administrative districts lie completely with-in Riga region and close to Riga city (see Fig. 1). The total area of these districts is 44,158 ha out of which forest stands cover 36,064 ha (82%). Thus the Riga municipality forests of those 4 districts cover only 17% of the total forest area of the Region. The dominant tree species in the municipally owned forests are Scots32J.Donis:Designating a greenbelt around the city of Riga,LatviaUrban For.Urban Green.2 (2003)Table 1.Tree species composition in the Riga region Dominant tree Area covered, ha Average age, years species––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––Total Municipa-Total Municipa-lity*lity* Scots pine95,27627,3718581 Norway spruce20,8493,0175139Birch30,5585,1246056 Other10,438552––Total157,12136,0647369*Data only for the 4 forest districts of the Riga city munici-pality that are entirely situated within the Riga region.pine, birch and Norway spruce. These cover 76%, re-spectively 14% and 8% of the forest area. Other species cover less than 2% of the area.Until the re-establishment of Latvian independence almost all forestland was owned by the state but since then many areas have been returned to their former owners and are now privately owned. Current regula-tions state that until the designation of new boundaries for protection belts has been agreed upon, all forests of the previously existing and protected green zone have to remain protected whatever their functional role or ownership status. Consequently almost all forests of the Riga municipality located in the Riga region have management restrictions placed on them, and the same can be said for forests of other owners within the previ-ously existing green zone. Currently, therefore, on the one hand significant recreation opportunities for urban dwellers are provided, while on the other hand forest owners’rights to obtain income from timber harvest in the suburban areas continue to be restricted. Suburban municipalities also lose income because of reduced land taxes from land with management restrictions.The board of Forests of the Municipality of Riga there-fore initiated the preparation of a proposal to designate a new protection belt.Study to support protection belt designation The main objective of the study presented here has been to obtain background information in preparation for further discussions with local municipalities. Stud-ies in Latvia as well as elsewhere have revealed that recreational values of forests depend mainly on forest characteristics, location and level of pollution (Emsis et al. 1979; Emsis 1989; Holgen et al. 2000; Lindhagen & Hörnsten 2000; Rieps ˇas 1994; Su ¯na 1973, 1979). A very important aspect is the distance to the forest from places where people live (e.g. Rieps ˇas 1994). The abil-ity of a forest stand to purify the air by filtering or ab-sorbing dust, micro-organisms, and noxious gases de-pends on tree and shrub species composition, age, tree size and stand density (Emsis 1989). Stands purify the air most effectively at the time of maximum current an-nual volume increment, usually between 30 to 60 years of age in Latvian conditions, depending on species.Recreational value, on the other hand, increases with age (and tree size) and reaches its maximum consider-ably later. Taking into account the peculiarities of the dispersal of pollution as described by Laivin ‚s ˇ et al.(1993) and Za ¯lı¯tis (1993), selective cutting is prefer-able in the vicinity of a pollution source, especially ifJ.Donis:Designating a greenbelt around the city of Riga,Latvia 33Urban For.Urban Green.2 (2003)Fig. 1.Location ofthe Riga municipali-ty forests in the Riga region.the forest consists of a narrow strip between the pollu-tion source and housing. If the distance between a pol-lution source and housing exceeds several kilometres, a patch clear-cut system with stands of different ages is sufficient to provide a reduction in the negative impact of urban areas. Taking into account the fact that closer to residential areas it is more important to consider the visual qualities of the forest (e.g. Tyrväinen et al. 2003), this purification ability can generally be ignored when planning protection belts.MethodsThis study to support the designating of the Riga pro-tection belt used the following data sources for analysis (see Fig. 2): forest inventory databases, digital forest maps of the Riga municipal forests which are situated outside the administrative borders of the city (55,600 ha of which 44,158 ha located in the Riga region) (see Fig. 1), and corresponding topographic maps.The study and its developed proposal are based on an application of a theoretical approach developed during the 1980s by the Latvian State Forestry Research Insti-tute ‘Silava’(Emsis 1989) and the Lithuanian Forestry Research Institute (Riepsˇas 1994). According to the methodology developed by Emsis (1989), the first step in the process is to evaluate the recreational potential of the forest stands. This is carried out by analysing the following factors:• The tolerance of the forest ecosystem to different lev-els of anthropogenic (recreation) loading;• the status of forest ecosystems in terms of the damage or degradation as a result of recreational use;•the suitability of the landscape for non-utilitarian recreation (recreational value); and• the existing and potential levels of recreational loads.The second step involves evaluating the existing andexpected functional roles of the forest.The tolerance of the forest ecosystem to different levels of anthropogenic impact or loading is evaluated using a framework based on a combination of forest type, dominant tree species, dominant age group, soil type and relief, according to the stability of ecosystem. All stands are classified into one of five tolerance classes. The highest score is given to mature deciduous forests on mesotrophic and mesic soils on flat topogra-phy, while the lowest score is given to young pine stands on oligotrophic soils on steep slopes (forests on dunes).In this study ecosystem tolerance could not be evalu-ated, as it was primarily a desk using existing databas-es, and topographic relief maps were not available in digital form. The status of the forest ecosystem in rela-tion to damage or degradation was evaluated in terms of the degree of change in vegetation cover, under-growth, tree root exposure of the and level of littering, classified into three classes.Assessment of the recreational value of the forest stands was calculated using a formula developed by Riepsˇas (1994):Recreational value VR= (VS*kW*kS+VA)*kPWhere VSis stand suitability based on key internal at-tributes of the stand, such as species, age, stand densityand forest type.

VA is an additional value depending on the pres-ence of attractive features, for example, 25 for forest stands up to 500 m from settlements, including summer cottages, or for areas intensively used for recreation ac-cording to information of local foresters. kP is a coeffi-cient depending on the level of environmental pollu-tion. Its value is 0 if the actual pollution level exceeds limit values, 0.5 if the level of environment pollution is between 50% and 100% of limit values, and 1 if the level of actual pollution is less than 50% of the limit values. In this study a coefficient of 1.0 was used, be-cause SO2and O3concentrations measured by Rigabackground measuring stations did not exceed 50% of the limit values (Fammler et al. 2000).The division of stands into classes of stand suitabili-ty is based on studies of visitors’preferences. Coeffi-cients kw, ksand VAare based on visitors’spatial distri-bution and show the ratio of the number of visitors in different zones. The evaluation of existing and expect-ed recreational loads was carried out by local foresters. They marked existing and potential recreation places on forest maps, including:•Small areas or sites for activities such as swimming, barbecuing, and so forth.•Recreation territories, defined as areas of 20 ha or more where people stay longer periods for walking, jogging, skiing or other forms of both active and pas-sive recreation.•Traditionally popular places for the collection of berries and mushrooms.•Recreational routes, including routes from public transport stops to recreation sites or recreation terri-tories, and between recreation sites and territories. For each recreation site and recreation territory data on the main seasons of use, the periods of use (week-days, weekends), and the average number of people in ‘rush-hours’during good weather conditions was col-lected or estimated.Data processing was carried out using ArcView GIS3.2a, Visual Fox pro and Microsoft Excel. VS values foreach stand were calculated from information in the for-est database using Visual Fox pro. Information collect-ed at a later stage from local foresters was digitised using separate themes (layers) in ArcView GIS 3.2a. Buffer zones along watercourses and water bodies, as well as residential areas, recreation sites and territoriesand recreation routes were created to get kW ,kSand VAvalues for each stand. Then VR values were calculatedfor each stand.A selection of recreation sites and territories was vis-ited by members of the project team in order to evalu-ate the state of the ecosystem with respect to wear and tear arising from different levels of recreational use. An evaluation of the existing functional role of each forest stand was carried out using the existing categories offorest protection. The anticipated future functional role was evaluated by annalysing the recreational value of stands, known expectations in terms of territorial de-velopment, and existing legal restrictions in order to find a compromise between recreation possibilities and other services of the forest. Next, a first draft of the protection belt was drawn according to experts’judge-ment. This draft included forests with high recreational value adjacent to residential areas and summer cot-tages, and larger tracts intensively used for recreation with medium to high recreational value.ResultsAccording to the original forest classification 65% of the total forest land area was designated as a commer-cial greenbelt forest, for which the main management goals are timber production and environmental consid-erations. The remaining 35% were designated as pro-tected (see Table 2). With regards to protected areas in Latvia: the main management goals of nature parks are nature conservation and recreation, including some ed-ucation. The goal for nature reserves is nature conser-vation, while that of the protected greenbelt forests is recreation.While interviewing local foresters it was revealed that they find it difficult to evaluate dispersed recreation loads (for example collection of berries, mushrooms). The assessments of foresters varied greatly and were considered to be unreliable. It was therefore decided to map only the places important for recreation, but not to use the inaccurate estimates of visitor numbers.In Latvia, special investigations have to be carried out in order to develop management objectives and principles for protected forests as part of the preparation of management plans. Pilot studies and visits to some of the recreation areas have revealed that the evaluation of the state of the forest ecosystem is useful only when de-veloping the detailed management plan. Even then, this is only the case for places identified by local foresters as recreation sites or territories, because otherwise it is too time consuming to carry out fieldwork which provides little useful additional information.Calculated VSvalues show that on average the forests studied have a medium suitability value for recreation (average score 47) (see Table 2). There are considerable differences between districts, with aver-age value ranging from 32 points in Olaine to 66 points in the Garkalne district. This indicates that the average stands in the Garkalne district are more suitable for recreation than those in other districts. If other aspects are taken into account, such as distance from wherepeople live, and VRvalues are calculated it can be seenJ.Donis:Designating a greenbelt around the city of Riga,Latvia35Urban For.Urban Green.2 (2003)that the districts are still ranked as follows: Garkalne,Jugla, Tireli and Olaine.Only 10% of the forest owned by Riga municipality within the Riga region were evaluated as having a high or very high recreational value. 12% had medium recreational value, while large areas used for the col-lection of berries and mushrooms were evaluated as having low or very low recreational value (60% of the total forest area) (see Table 3).More than 16% of the area is covered by bogs, for which according to the used methodology, recreational value was not evaluated at all. Some areas were recorded by the local foresters as important places for the collec-tion of berries. However, more valuable from a recre-ational point of view were those forests situated east and north-east of the city (Garkalne and Jugla districts),while the forests to the south (Olaine and Tireli districts)were found to have a lower recreational value (V R ).36J.Donis:Designating a greenbelt around the city of Riga,LatviaUrban For.Urban Green.2 (2003)Table 2.Distribution of forest by forest categories according to the original functional role Forest districtDataFormer forest category Total–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––Commercial Nature Nature Protected greenbelt forests parks reserves greenbelt forestsGarkalneArea, ha521.27,698.78,219.9Average of V S *61.966.566.2Average of V R **59.350.751.4JuglaArea, ha 8,376.74,098.812,475.4Average of V S 45.656.949.1Average of V R 22.034.025.7OlaineArea, ha 11,765.4707.512,473.0Average of V S 31.941.032.6Average of V R 8.527.410.0TireliArea, ha 8,689.5257.91,025.01,016.910,989.3Average of V S 40.666.710.059.342.3Average of V R 17.055.3 1.044.920.6TotalArea, ha 28,831.6779.11,025.013,522.044,157.6Average of V S 39.863.510.061.647.1Average of V R16.357.91.043.725.9* V S Suitability value – based on stand parameters (0–100 points).** V R Recreation value (0–125 points) based on stand parameters, distance to the residential areas, water and other attractive objects.Table 3.Distribution of forest areas by classes of attractiveness and by designated functional role Designated zoneDataClass of attractiveness Total –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––n.a.Very low Low Medium High Very high 0<2525,1–5051–7575–100100<Protection belt Area, ha76.7560.12,266.42,222.7850.5743.66719.9Average of V R *0.012.036.063.390.0125.053.4Visually sensitive Area, ha 447.64,150.54,157.7853.4847.1179.810636.1Average of V R 0.07.837.460.996.7125.028.5Non-restricted Area, ha 6,664.715,389.12,548.61,090.5874.8234.026801.7Average of V R 0.0 5.234.761.197.2125.015.8TotalArea, ha 7,189.020,099.88,972.74,166.52,572.31,157.344157.6Average of V R0.06.236.362.294.6125.025.9*V R Recreation value (0–125 points) based on stand parameters, distance to the residential areas, water and other attractive objects.Areas along main roads and railways are known to be visually sensitive, because of the large number of peo-ple who can see them during travel. The same is true for forest in the vicinity of small villages. Taking into ac-count the fact that legislation prohibits clear-cuts in pro-tection belts – which is not always necessary in order to maintain the visual quality of the landscape – it was proposed, as part of the zoning strategy, to create so called visually sensitive areas. In these areas the forest owner (Riga municipality) is recommended to use more detailed landscape-planning techniques and to pay more attention to visual aspects during management.As a result of the study, seen from a recreational point of view and taking into account legal restrictions and so forth, it has been proposed to create three zoning categories: (1) protection belts, (2) visually-sensitive areas, and (3) non-restricted areas (see Fig. 3). The protection belt should include:• Forest with high recreational value adjacent to residen-tial areas and summer cottages, to form a 200–500 m wide belt.• Larger tracts of forestland intensively used for recre-ation.The zone of visually-sensitive areas should include:• Forests within the administrative borders of Riga mu-nicipality and in the vicinity of villages (up to 200–500 m distance).• Forests along roads of national and regional impor-tance, railways, watercourses and streams as a protec-tion belt of 100–300 m wide.• Places used for mushroom and berry collection in the original restricted protection belt.• Places that could become important for recreation in the near future.J.Donis:Designating a greenbelt around the city of Riga,Latvia 37Urban For.Urban Green.2 (2003)Table 4.Proposed distribution of forest categories in designated zones (in hectares)Designated zoneFormer forest category Grand Total––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––Commercial Nature Nature Protected greenbelt forests parks reserves greenbelt forests Protection belt355.2779.15,585.76,719.9Visually sensitive areas 3,503.97,132.110,636.1Non-restricted areas 24,972.51,025.0*804.226,801.7Total 28,831.6779.11,025.013,522.044,157.6*Forests within nature reserves are not intended for recreation; their primary management goal is nature conservation.Fig. 3.Proposal for zon-ing of the Riga municipalforests in Riga region.The remaining areas should consequently be classi-fied as non-restricted areas.A revision of the first draft plan was made taking into account the known prospective development plans of Riga and Riga region. As a result, for forests owned by Riga municipality and located in Riga region the pro-posal is to include 6,720 ha in the protection belt (see Table 3). Moreover, it has been suggested to designate 10,636 ha as visually-sensitive areas, but to omit the re-maining 26,802 ha from zoning, as these do not need special management from a recreation point of view. Average recreational values of stands in this area range from 53 (medium), through 28 (low) to 15 points (very low) respectively.As a result, the major part of the forest remains in the same functional category as in the original allocation (see Table 4). As was mentioned above, the classifica-tion described here is only based on recreational as-pects, thus forests in nature reserves are misleadingly shown as non-restricted forests. Only 5,586 ha out of the 13,500 thousand ha of the originally protected greenbelt forests are proposed to be included in the protection belt, while 355 ha of the previous commer-cial greenbelt forests are proposed to be placed under stronger protection.DiscussionForests owned by Riga municipality within the Riga re-gion are divided over 13 rural municipalities. Accord-ing to legislation, revised draft proposals for zoning Riga city forests have to be accepted by Riga munici-pality, while the final decision is up to Riga and the sur-rounding municipalities. The study presented here has provided a tentative estimate of the recreational value and suitability of the forests for recreation and can be used as a starting point for political discussions. At the very beginning the intention was to divide the forests in two categories: the protection belt and the remainder of the forest. During the study it was concluded, however, that a third category would be needed, that of visually sensitive areas. Within this category more attention would have to be paid to the amenity of the landscape, but there would be no need to drastically restrict com-mercial forest management. As nature parks are also designated for recreation, it has been proposed to in-clude all forests of nature parks in the protection belt. It has to be noted that all the forests within the adminis-trative borders of cities, and as such not included in this study, are designated as protected. As a consequence, the forest area available for recreation to the inhabi-tants of Riga would increase to 12,500 ha.Unlike many other European cities, where timber ex-traction is of small importance (Konijnendijk 1999),Riga municipal forests have a considerable economic role. It is estimated that the allowable annual cut in suburban forests amounts to 169,800 m3or 81% of the annual increment (Dubrovskis et al. 2002). It should be kept in mind that income from logging is used for for-est regeneration and tending, forest fire protection and maintenance of recreation facilities.The objective of this study was not to evaluate the precision of the method nor possible errors occurring when applying it. This study revealed, however, the in-completeness of the methodology used. Bogs, which are very sensitive to recreation loads, are ascribed quite a high level of attractiveness from a recreation point of view (for the collection of wild berries), but according to the methodology they are not evaluated at all. All watercourses were assumed to be attractive sites, while the preliminary evaluation of recreation loads showed this not to be true. The use of watercourses is very vari-able and obviously depends on water quality and vege-tation structure of the edges or banks. Another aspect which was not taken into account was that amenity of a forest is not simply the sum of the amenity values of forest stands (Pukkala et al. 1995).It seems that the evaluation based on dominant species is appropriate for screening areas, but for more detailed management plans, species mixture, the number of forest layers, and principles of landscape architecture also have to be taken into account (Bell 1999; Bell & Nikodemus 2000). Various studies have shown that people prefer uneven-aged forests (e.g. Melluma et al. 1982) and uneven-aged stands (e.g. Riepsˇas 1994). The impacts of the screening effect show that there are, even in the visually-sensitive and commercial zones, considerable areas with high and very high recreational value. This is mainly because delineation of zonal boundaries is carried out using easily distinguishable natural lines, and often it is not worth including single stands of high recreational value in the protection belt if, as a consequence, re-strictions on management would be placed over whole compartments of 50 ha.For the preparation of specific management guide-lines detailed field inventories have to be carried out. This has not been done in this study, where more re-liance was placed on the experience of local foresters and existing databases. Detailed economical calcula-tions have yet to be carried out in order to evaluate the direct and indirect value of the forest. These will also assist in obtaining more background information to be used as part of a holistic approach and for development of a decision support system to resolve contradictions between different interest groups.After acceptance of the draft plan by the municipali-ty of Riga, the process of negotiation between Riga and its surrounding municipalities is currently ongoing.38J.Donis:Designating a greenbelt around the city of Riga,Latvia Urban For.Urban Green.2 (2003)。

2. WHAT CONSTITUTES FAIR DEALINGWEINBERGER v. UOP, INC.457 A.2d 701 (Del.Supr.19a3).MOORE, JUSTICE.This post-trial appeal was reheard en banc from a decision of the Court of Chancery. It was brought by the class action plaintiff below, a former shareholder of UOP, Inc., who challenged the elimination of UOP's minority shareholders by a cash-out merger between UOP and its majority owner, The Signal Companies, Inc. Originally, the defendants in this action were Signal, UOP, certain officers and directors of those companies, and UOP's investment banker, Lehman Brothers Kuhn Loeb, Inc. The present Chancellor held that the terms of the merger were fair to the plaintiff and the other minority shareholders of UOP. Accordingly, he entered judgment in favor of the defendants.Numerous points were raised by the parties, but we address only the following questions presented by the trial court's opinion:1) The plaintiffs duty to plead sufficient facts demonstrating the unfairness of the challenged merger;2) The burden of proof upon the parties where the merger has been approved by the purportedly informed vote of a majority of the minority shareholders;3) The fairness of the merger in terms of adequacy of the defendants' disclosures to the minority shareholders;4) The fairness of the merger in terms of adequacy of the price paid for the minority shares and the remedy appropriate to that issue; and5) The continued force and effect of Singer v. Magnavox Co., Del.Supr., 380 A.2d 969, 980 (1977), and its progeny.In ruling for the defendants, the Chancellor re-stated his earlier conclusion that the plaintiff in a suit challenging a cash-out merger must allege specific acts of fraud, misrepresentation or other items of misconduct to demonstrate the unfairness of the merger terms to the minority. We approve this rule and affirm it.The Chancellor also held that even though the ultimate burden of proof is on the majority shareholder to show by a preponderance of the evidence that the transaction is fair, it is first the burden of the plaintiff attacking the merger to demonstrate some basis for invoking the fairness obligation. We agree with that principle. However, where corporate action has been approved by an informed vote of a majority of the minority shareholders, we conclude that the burden entirely shifts ^ to the plaintiff to show that the transaction was unfair to the minority^- But in all this, the burden clearly remains on those relying on the vote to show that they completely disclosed all material facts relevant to the transaction.Here, the record does not support a conclusion that the minority stockholder vote was an informed one. Material information, necessary to acquaint those shareholders with the bargaining positions of Signal and UOP, was withheld under circumstances amounting to a breach of fiduciary duty. We therefore conclude that this merger does not meet the test of fairness, at least as we address that concept, and no burden thus shifted to the plaintiff by reason of the minority shareholder vote. Accordingly, we reverse and remand for further proceedings consistent herewith.In considering the nature of the remedy available under our law to minority shareholders in a cash-out merger, we believe that it is, and hereafter should be, an appraisal under 8 Del.C. § 262 as hereinafter construed. We therefore overrule Lynch v. Vickers Energy Corp., Del. Supr., 429 A.2d 497 (1981) {Lynch II) to the extent that it purports to limit a stockholder's monetary relief to a specific damage formula. But to give full effect to section 262 within the framework of the General Corporation Law we adopt a more liberal, less rigid and stylized, approach to the valuation process than has heretofore been permitted by our courts. While the present state of these proceedings does not admit the plaintiff to the appraisal remedy per se, the practical effect of the remedy we do grant him will be co-extensive with the liberalized valuation and appraisal methods we herein approve for cases coming after this decision.Our treatment of these matters has necessarily led us to a reconsideration of the business purpose rule announced in the trilogy of Singer A v. Magnavox Co., supra; Tanzer v. International General Industries, JT > Inc., DeL.Supr., 379 A.2d 1121 (1977); and Roland International Corp. v. Najjar, Del.Supr., 407 A.2d 1032 (1979). For the reasons hereafter set forth we consider that the business purpose requirement of these cases v J is no longer the law of Delaware.The facts found by the trial court, pertinent to the issues before us, are supported by the record, and we draw from them as set out in the Chancellor's opinion.Signal is a diversified, technically based company operating through various subsidiaries. Its stock is publicly traded on the New York, Philadelphia and Pacific Stock Exchanges. UOP, formerly known as Universal Oil Products Company, was a diversified industrial company engaged in various lines of business, including petroleum and petro-chemical services and related products, construction, fabricated metal products, transportation equipment products, chemicals and plastics, and other products and services including land development, lumber products and waste disposal. Its stock was publicly held and listed on the New York Stock Exchange.In 1974 Signal sold one of its wholly-owned subsidiaries for $420,000,000 in cash. See Gimbel v. Signal Companies, Inc., Del.Ch., 316 A.2d 599, aff’d, Del.Supr., 316 A.2d 619 (1974). While looking to invest this cash surplus, Signal became interested in UOP as a possible acquisition. Friendly negotiations ensued, and Signal proposed to acquire a controlling interest in UOP at a price of $19 per share. UOP's representatives sought $25 per share. In the arm's length bargaining that followed, an understanding was reached whereby Signal agreed to purchase from UOP 1,500,000 shares of UOP's authorized but unissued stock at $21 per share.This purchase was contingent upon Signal^ making a successful cash tender offer for 4,300,000 publicly held shares of UOP, also at a price of $21 per share. This combined method of acquisition permitted Signal to acquire 5,800,000 shares of stock, representing 50.5% of UOP's outstanding shares. The UOP board of directors advised the company's shareholders that it had no objection to Signal's tender offer at that price. Immediately before the announcement of the tender offer, UOP's common stock had been trading on the New York Stock Exchange at a fraction under $14 per share.The negotiations between Signal and UOP occurred during April 1975, and the resulting tender offer was greatly oversubscribed. However, Signal limited its total purchase of the tendered shares so that, when coupled with the stock bought from UOP, it had achieved its goalof becoming a 50.5% shareholderAlthough UOP’ board consisted of thirteen directors, Signal nominated and elected only six. Of these, five were either directors or employees of Signal. The sixth, a partner in the banking firm of Lazard Freres & Co., had been one of Signal's representatives in the negotiations and bargaining with UOP concerning the tender offer and purchase price of the UOP shares.However, the president and chief executive officer of UOP retired during 1975, and Signal caused him to be replaced by James V. Crawford, a long-time employee and senior executive vice president of one of Signal's wholly-owned subsidiaries. Crawford succeeded his predecessor on UOP's board of directors and also was made a director of Signal.By the end of 1977 Signal basically was unsuccessful in finding other suitable investment candidates for its excess cash, and by February 1978 considered that it had no other realistic acquisitions available to it on a friendly basis. Once again its attention turned to UOP.The trial court found that at the instigation of certain Signal management personnel, including William W. Walkup, its board chairman, and Forrest N. Shumway, its president, a feasibility study was made concerning the possible acquisition of the balance of UOP's outstanding shares. This study was performed by two Signal officers, Charles S. Arledge, vice president (director of planning), and Andrew J. Chitiea, senior vice president (chief financial officer). Messrs. Walkup, Shumway, Arledge and Chitiea were all directors of UOP in addition to their membership on the Signal board.Arledge and Chitiea concluded that it would be a good investment for Signal to acquire the remaining 49.5% of UOP shares at any price up to $24 each. Their report was discussed between Walkup and Shumway who, along with Arledge, Chitiea and Brewster L. Arms, internal counsel for Signal, constituted Signal's senior management. In particular, they talked about the proper price to be paid if the acquisition was pursued, purportedly keeping in mind that as UOP's majority shareholder, Signal owed a fiduciary responsibility to both its own stockholders as well as to UOP's minority. It was ultimately agreed that a meeting of Signal's Executive Committee would be called to propose that Signal acquire the remaining outstanding stock of UOP through a cash-out merger in the range of $20 to $21 per share.The Executive Committee meeting was set for February 28, 1978. As a courtesy, UOP's president, Crawford, was invited to attend, although he was not a member of Signal's executive committee. On his arrival, and prior to the meeting, Crawford was asked to meet privately with Walkup and Shumway. He was then told of Signal's plan to acquire full ownership of UOP and was asked for his reaction to the proposed price range of $20 to $21 per share. Crawford said he thought such a price would be "generous", and that it was certainly one which should be submitted to UOP's minority shareholders for their ultimate consideration. He stated, however, that Signal's 100% ownership could cause internal problems at UOP. He believed that employees would have to be given some assurance of their future place in a fully- owned Signal subsidiary. Otherwise, he feared the departure of essential personnel. Also, many of UOP's key employees had stock option incentive programs which would be wiped out by a merger. Crawford therefore urged that some adjustment would have to be made, such as providing a comparable incentive in Signal's shares, if after the merger he was to maintain his quality of personnel and efficiency at UOP.Thus, Crawford voiced no objection to the $20 to $21 price range, nor did he suggest that Signal should consider paying more than $21 per share for the minority interests. Later, at the Executive Committee meeting the same factors were discussed, with Crawford repeating the position he earlier took with Walkup and Shumway. Also considered was the 1975 tender offer andthe fact that it had been greatly oversubscribed at $21 per share. For many reasons, Signal's manage¬ment concluded that the acquisition of UOP's minority shares provided the solution to a number of its business problems.Thus, it was the consensus that a price of $20 to $21 per share would be fair to both Signal and the minority shareholders of UOP. Signal's executive committee authorized its management "to negotiate" with UOP "for a cash acquisition of the minority ownership in UOP, Inc., with the intention of presenting a proposal to [Signal's] board of directors * * * on March 6, 1978". Immediately after this February 28, 1978 meeting, Signal issued a press release stating: The Signal Companies, Inc. and UOP, Inc. are conducting negotiations for the acquisition for cash by Signal of the 49.5 per cent of UOP which it does not presently own, announced Forrest N. Shumway, president and chief executive officer of Signal, and James V. Crawford, UOP president. Price and other terms of the proposed transaction have not y et been finalized and would be subject to approval of the boards of directors of Signal and UOP, scheduled to meet early next week, the stockholders of UOP and certain federal agencies.The announcement also referred to the fact that the closing price of UOP's common stock on that day was $14.50 per share.Two days later, on March 2, 1978, Signal issued a second press release stating that its management would recommend a price in the range of $20 to $21 per share for UOP's 49.5% minority interest. This announcement referred to Signal's earlier statement that "negotiations" were being conducted for the acquisition of the minority shares.Between Tuesday, February 28, 1978 and Monday, March 6,1978, a total of four business days, Crawford spoke by telephone with all of UOP's non-Signal, i.e., outside, directors. Also during that period, Crawford retained Lehman Brothers to render a fairness opinion as to the price offered the minority for its stock. He gave two reasons for this choice. First, the time schedule between the announcement and the board meetings was short (by then only three business days) and since Lehman Brothers had been acting as UOP's investment banker for many years, Crawford felt that it would be in the best position to respond on such brief notice. Second, James W. Glanville, a long-time director of UOP and a partner in Lehman Brothers, had acted as a financial advisor to UOP for many years. Crawford believed that Glanville's familiarity with UOP, as a member of its board, would also be of assistance in enabling Lehman Brothers to render a fairness opinion within the existing time constraints.Crawford telephoned Glanville, who gave his assurance that Lehman Brothers had no conflicts that would prevent it from accepting the task. Glanville's immediate personal reaction was that a price of $20 to $21 would certainly be fair, since it represented almost a 50% premium over UOP's market price. Glanville sought a $250,000 fee for Lehman Brothers' services, but Crawford thought this too much. After further discussions Glanville finally agreed that Lehman Brothers would render its fairness opinion for $150,000.During this period Crawford also had several telephone contacts with Signal officials. In only one of them, however, was the price of the shares discussed. In a conversation with Walkup, Crawford advised that as a result of his communications with UOP's non-Signal directors, it was his feeling that the price would have to be the top of the proposed range, or $21 per share, if the approval of UOP's outside directors was to be obtained. But again, he did not seek any price higher than $21.Glanville assembled a three-man Lehman Brothers team to do the work on the fairness opinion. These persons examined relevant documents and information concerning UOP, including its annual reports and its Securities and Exchange Commission filings from 1973 through 1976, as well as its audited financial statements for 1977, its interim reports to shareholders, and its recent and historical market prices and trading volumes. In addition, on Friday, March 3, 1978, two members of the Lehman Brothers team flew to UOP's headquarters in Des Plaines, Illinois, to perform a "due diligence" visit, during the course of which they interviewed Crawford as well as UOP's general counsel, its chief financial officer, and other key executives and personnel.As a result, the Lehman Brothers team concluded that "the price of either $20 or $21 would be a fair price for the remaining shares of UOP". They telephoned this impression to Glanville, who was spending the weekend in Vermont.On Monday morning, March 6, 1978, Glanville and the senior member of the Lehman Brothers team flew to Des Plaines to attend the scheduled UOP directors meeting. Glanville looked over the assembled information during the flight. The two had with them the draft of a "fairness opinion letter" in which the price had been left blank. Either during or immediately prior to the directors' meeting, the two-page "fairness opinion letter" was typed in final form and the price of $21 per share was inserted.On March 6, 1978, both the Signal and UOP boards were convened to consider the proposed merger. Telephone communications were maintained between the two meetings. Walkup, Signal's board chairman, and also a UOP director, attended UOP's meeting with Crawford in order to present Signal's position and answer any questions that UOP's non-Signal directors might have. Arledge and Chitiea, along with Signal's other designees on UOP's board, participated by conference telephone. All of UOP's outside directors attended the meeting either in person or by conference telephone.First, Signal's board unanimously adopted a resolution authorizing Signal to propose to UOP a cash merger of $21 per share as outlined in a certain merger agreement, and other supporting documents. This proposal required that the merger be approved by a majority of UOP's outstanding minority shares voting at the stockholders meeting at which the merger would be considered, and that the minority shares voting in favor of the merger, when coupled with Signal's 50.5% interest would have to comprise at least two-thirds of all UOP shares. Otherwise the proposed merger would be deemed disapproved.UOP's board then considered the proposal. Copies of the agreement were delivered to the directors in attendance, and other copies had been forwarded earlier to the directors participating by telephone. They also had before them UOP financial data for 1974-1977, UOP's most recent financial statements, market price information, and budget projections for 1978. In addition they had Lehman Brothers' hurriedly prepared fairness opinion letter finding the price of $21 to be fair. Glanville, the Lehman Brothers partner, and UOP director, commented on the information that had gone into preparation of the letter.Signal also suggests that the Arledge-Chitiea feasibility study, indicating that a price of up to $24 per share would be a "good investment" for Signal, was discussed at the UOP directors' meeting. The Chancellor made no such finding, and our independent review of the record, detailed infra, satisfies us by a preponderance of the evidence that there was no discussion of this document at UOP's board meeting. Furthermore, it is clear beyond peradventure that nothing in that report was ever disclosed to UOP's minority shareholders prior to their approval of themerger.After consideration of Signal's proposal, Walkup and Crawford left the meeting to permit a free and uninhibited exchange between UOP's non-Signal directors. Upon their return a resolution to accept Signal's offer was then proposed and adopted. While Signal's men on UOP's board participated in various aspects of the meeting, they abstained from voting. However, the minutes show that each of them "if voting would have voted yes".On March 7, 1978, UOP sent a letter to its shareholders advising them of the action taken by UOP's board with respect to Signal's offer. This document pointed out, among other things, that on February 28, 1978 "both companies had announced negotiations were being conducted".Despite the swift board action of the two companies, the merger was not submitted to UOP's shareholders until their annual meeting on May 26, 1978. In the notice of that meeting and proxy statement sent to shareholders in May, UOP's management and board urged that the merger be approved. The proxy statement also advised:The price was determined after discussions between James V. Crawford, a director of Signal and Chief Executive Officer of UOP, and officers of Signal which took place during meetings on February 28, 1978, and in the course of several subsequent telephone conversations. (Emphasis added.)In the original draft of the proxy statement the word "negotiations" had been used rather than "discussions". However, when the Securities and Exchange Commission sought details of the "negotiations" as part of its review of these materials, the term was deleted and the word "discussions" was substituted. The proxy statement indicated that the vote of UOP's board in approving the merger had been unanimous. It also advised the shareholders that Lehman Brothers had given its opinion that the merger price of $21 per share was fair to UOP's minority. However, it did not disclose the hurried method by which this conclusion was reached.As of the record date of UOP's annual meeting, there were 11,488,302 shares of UOP common stock outstanding, 5,688,302 of which were owned by the minority. At the meeting only 56%, or 3,208,652, of the minority shares were voted. Of these, 2,953,812, or 51.9% of the total minority, voted for the merger, and 254,840 voted against it. When Signal's stock was added to the minority shares voting in favor, a total of 76.2% of UOP's outstanding shares approved the merger while only 2.2% opposed it.By its terms the merger became effective on May 26, 1978, and each share of UOP's stock held by the minority was automatically converted into a right to receive $21 cash.II.A.A primary issue mandating reversal is the preparation by two UOP directors, Arledge and Chitiea, of their feasibility study for the exclusive use and benefit of Signal. This document was of obvious significance to both Signal and UOP. Using UOP data, it described the advantages to Signal of ousting the minority at a price range of $21-$24 per share. Mr. Arledge, one of the authors, outlined the benefits to Signal:Purpose Of The Merger1) Provides an outstanding investment opportunity for Signal—(Better than any recent acquisition we have seen.)2) Increases Signal's earnings.3) Facilitates the flow of resources between Signal and its subsidiaries(Big factor—works both ways.)4) Provides cost savings potential for Signal and UOP.5) Improves the percentage of Signal's 'operating earnings' as opposed to 'holding company earnings'.6) Simplifies the understanding of Signal.7) Facilitates technological exchange among Signal's subsidiaries.8) Eliminates potential conflicts of interest.Having written those words, solely for the use of Signal it is clear from the record that neither Arledge nor Chitiea shared this report with their fellow directors of UOP. We are satisfied that no one else did either. This conduct hardly meets the fiduciary standards applicable to such a transaction * * *The Arledge-Chitiea report speaks for itself in supporting the Chancellor's finding that a price of up to $24 was a "good investment" for Signal. It shows that a return on the investment at $21 would be 15.7% versus 15.5% at $24 per share. This was a difference of only two-tenths of one percent, while it meant over $17,000,000 to the minority. Under such circumstances, paying UOP's minority shareholders $24 would have had relatively little long-term effect on Signal, and the Chancellor's findings concerning the benefit to Signal, even at a price of $24, were obviously correct. Levitt v. Bouvier, Del.Supr., 287 A.2d 671, 673 (1972).Certainly, this was a matter of material significance to UOP and its shareholders. Since the study was prepared by two UOP directors, using UOP information for the exclusive benefit of Signal, and nothing whatever was done to disclose it to the outside UOP directors or the minority shareholders, a question of breach of fiduciary duty arises. This problem occurs because there were common Signal-UOP directors participating, at least to some extent, in the UOP board's decision making processes without full disclosure of the conflicts they faced.7B.In assessing this situation, the Court of Chancery was required to:examine what information defendants had and to measure it against what they gave to the minority stockholders, in a context in which 'complete candor' is required. In other words, the limited function of the Court was to determine whether defendants had disclosed all information in their possession germane to the transaction in issue. And by 'germane' we mean, for present purposes, information such as a reasonable shareholder would consider important. in Priding whether. to sell or retain stock.* * ** * * Completeness, not adequacy, is both the norm and the mandate under present circumstances. Lynch v. Vickers Energy Corp., Del.Supr., 383 A.2d 278, 281 (1977) (Lynch /). This is merely stating in another way the long-existing principle of Delaware law that these Signal designated directors on UOP's board still owed UOP and its shareholders an uncompromising duty of loyalty. The classic language of Guth v. Loft, Inc., Del.Supr., 5 A.2d 503, 510 (1939), requires no embellishment:A public policy, existing through the years, and derived from a profound knowledge of human characteristics and motives, has established a rule that demands of a corporate officer or director, peremptorily and inexorably, the most scrupulous observance of his duty, not only affirmatively to protect the interests of the corporation committed to his charge, but also to refrainfrom doing anything that would work injury to the corporation, or to deprive it of. profit or advantage which his skill and ability might properly bring to it, or to enable it to make in the reasonable and lawful exercise of its powers. The rule that requires an undivided and unselfish loyalty to the corporation demands that there shall be no conflict between duty and self-interest. Given the absence of any attempt to structure this transaction on an arm's length basis, Signal cannot escape the effects of the conflicts it faced, particularly when its designees on UOP's board did not totally abstain from participation in the matter. There is no "safe harbor" for such divided loyalties in Delaware. When directors of a Delaware ^ corporation are on both sides of a transaction, they are required to demonstrate their utmost good faith and the most scrupulous inherent P fairness of the bargain. Gottlieb v. Heyden Chemical Corp., Del.Supr., 91 A.2d 57, 57-58 (1952). The requirement of fairness is unflinching in v rP y demand that where one stands on both sides of a transaction, he has the burden of establishing its entire fairness, sufficient to pass the test of careful scrutiny by the courts. Sterling v. Mayflower Hotel Corp., N, Del.Supr., 93 A.2d 107, 110 (1952); Bastian v. Bourns, Inc., Del.Ch., 256 A.2d 680, 681 (1969), aff’d, Del.Supr., 278 A.2d 467 (1970); David J. Greene & Co. v. Dunhill International Inc., Del.Ch., 249 A.2d 427, 431 (1968).There is no dilution of this obligation where one holds dual or multiple directorships, as in a parent-subsidiary context. Levien v. Sinclair Oil Corp., Del.Ch., 261 A.2d 911, 915 (1969). Thus, individuals who act in a dual capacity as directors of two corporations, one of whom is parent and the other subsidiary, owe the same duty of good management to both corporations, and in the absence of an independent negotiating structure (see note 7, supra), or the directors' total abstention from any participation in the matter, this duty is to be exercised in light of what is best for both companies. Warshaw v. Calhoun, Del. Supr., 221 A.2d 487, 492 (1966). The record demonstrates that Signal has not met this obligation.。

外文翻译文献The Impact of Social Media on Mental HealthIntroductionIn recent years, with the rapid development of technology, social media has become an integral part of people's lives. It allows users to connect with others, share information, and express their opinions. While social media has many benefits, such as enhancing communication and facilitating information dissemination, it also has several negative effects on mental health. This paper will explore the impact of social media on mental health, including the increase in anxiety and depression, the pressure to maintain a perfect online image, and the addictive nature of social media.Increase in Anxiety and DepressionStudies have shown that the use of social media is associated with an increased risk of anxiety and depression. Constant exposure to the carefully curated lives of others on social media platforms can lead to feelings of inadequacy and low self-esteem. Users often compare themselves to others and may experience envy or jealousy, which can contribute to anxiety and depressive symptoms. Moreover, the fear of missing out (FOMO) is prevalent among social media users. Seeing others engaging in enjoyable activities or having a large number of friends can cause feelings of loneliness and isolation in individuals who are not experiencing the same level of social engagement. These feelings can contribute to the development or worsening of anxiety and depression.Pressure to Maintain a Perfect Online ImageSocial media platforms often promote an idealized version of reality, where individuals present only the highlights of their lives. These posts are carefully crafted, showing only the positive aspects of one's life and ignoring the negatives. This constant pressure to maintain a perfect online image can lead to feelings of inadequacy and low self-worth.Additionally, the need for validation and approval from others is heightened on social media. Users often measure their self-worth based on the number of likes, comments, or followers they have. The constant pursuit of validation can be mentally exhausting and can contribute to a negative self-image if one's posts do not receive the desired attention.Addictive Nature of Social MediaAnother significant impact of social media on mental health is its addictive nature. The constant availability of social media platforms on smartphones and other devices promotes excessive use and can lead to an addiction-like behavior. Individuals may find themselves spending hours scrolling through their feeds, neglecting their responsibilities, and isolating themselves fromreal-life interactions.The addictive nature of social media can also disrupt sleep patterns. The blue light emitted from screens can interfere with the production of melatonin, a hormone that regulates sleep. Studieshave shown that excessive social media use before bedtime can lead to poor sleep quality, which can have detrimental effects on mental health.ConclusionIn conclusion, while social media has its merits, it also has several negative effects on mental health. It can contribute to an increase in anxiety and depression, as well as a pressure to maintain a perfect online image. Additionally, the addictive nature of social media can lead to excessive use and disrupt sleep patterns. It is important for individuals to be mindful of their social media usage and take steps to prioritize their mental well-being.。

Wind turbine gearbox OverviewOverview:Wind turbine gearbox is an important mechanical components, and its main function is to wind round the momentum generated by wind is passed to the generator and make the appropriate speed. Usually wind wheel speed is very low, far less than required by the generator speed, the growth rate effect of the gearbox gear vice, so the gearbox will also be called a growth box. According to the general layout of the unit, sometimes the wind turbine wheel is directly connected to the drive shaft (commonly known as the shaft) and the gear box together as one, shaft and gearbox are arranged, during which the tension device or coupling connected structure. Brakes in order to increase the braking capacity of the unit, often set in the input or output of the gearbox, with the tip brake (fixed pitch wind wheel) or pitch from the brake to the unit drive system combined braking.Unit installed in the mountains, wilderness, beaches, islands and other outlet by the impact of erratic change to the variable load wind and strong gusts of perennial withstand extreme temperatures and extreme temperature variations, combined with the natural environment in which the traffic inconvenience, The gear box is installed in the narrow space within the tower, once the failure, repair is very difficult, so its reliability and service life are much higher than the average mechanical demands. For example, the requirements of the component materials, in addition to the normal state of the mechanical properties, but also should have the characteristics of low temperature resistance to cold brittleness; should ensure the smooth work of the gear box to prevent vibration and shock; to ensure adequate lubrication conditions, and so on. Huge temperature difference between summer and winter areas, to configure the appropriateheating and cooling devices. Also set up monitoring points remote operation and lubrication state.Different forms of wind turbines are not the same requirements, the arrangement of form and structure of the gearbox and therefore vary. The horizontal axis wind turbine in the wind power sector is the most common fixed parallel shaft gear drive and the planetary gear drive.As mentioned earlier, the wind power generation by natural conditions, the emergence of some special meteorological conditions, all of which might lead to the failure of wind turbine not like small cabin on the ground as a solid base foundation of the entire powertrain power matching and torsional vibration factor is always concentrated reflection of a weak link, and a lot of practice, this link is often the gearbox in unit. Therefore, the strengthening of the gearbox, the great importance of its maintenance work is particularly important.The design requirementsThe design must guarantee to meet the reliability and life expectancy under the premise, to simplify the structure and the lightest. Normally be by CAD design, schedule the best transmission scheme, the choice of design parameters, select reliable components and has good mechanical properties as well as in the environmental extreme temperature remains stable material, and so on.First, the design loadGearbox as components of the transmission of power during operation at the same time withstand the dynamic and static load. Dynamic load part depends on the wind wheel, the characteristics and the shaft of the generator, the quality of the coupling stiffness and damping values, as well as the generator of external working conditions. Load spectrum of the wind turbine gearbox design calculation on the basis of the load spectrum by the measured, calculated and determined in accordance withthe standards of the JB/T10300.When the spectrum calculated in accordance with the measured load, the gear box using the coefficient of the KA = 1. When can not get the load spectrum, take the KA = 1.3 for three-bladed wind turbine.Second, the design requirementsGrowth of wind turbine design parameters of the box, except as otherwise provided, is often used to optimize the design, namely the use of computer analysis and calculation, to obtain the optimal design program to meet the constraints.(A) EfficiencyThe efficiency of the gearbox power loss calculation or get measured in the experiment. The power loss including the gear meshing, bearing friction, lubricant splashing and mixing losses, windage loss, and other mechanical damping. The efficiency of the gear under different conditions is inconsistent.Wind turbine gearbox professional standards require that the mechanical efficiency of the gear box should be greater than 97%, refers to the indicators to be achieved under standard conditions.(B) noise levelNoise standards for wind power growth rate box for around 85dB (A). The noise from the various transmission parts, it should take the appropriate measures to reduce noise:1.appropriate increase in the precision gears, tooth repair edge to increase the engagement degree of coincidence;2 .increase the stiffness of the shaft and bearing;3.rational arrangement of the shaft and the transmission gear train, to avoid resonance;4. Installation to take the necessary damping mechanical vibration of the gearbox control GB/T8543 the provisions of the C(C) ReliabilityIn accordance with the requirements of the assumed life expectancy of at least 20 years, depending on the load spectrum listed in the load distribution of the fatigue analysis, limit state of the whole and parts of the gear box design and the use of limit state, ultimate strength analysis, fatigue analysis, stability, and deformation limits analysis, dynamic analysis. Analysis methods can be simulated host operating conditions in addition to the usual recommended design calculation method of component testing.The reliability analysis must be carried out in the beginning of the program design, and again after the completion of the construction design of a detailed reliability analysis of computing, including carefully selected good reliability structures and the reliability of estimates of important spare parts and machine.Gear boxMany different types of wind turbine gearbox in accordance with the conventional type can be divided into the growth of cylindrical gear boxes, planetary growth box, gear box as well as their combination with each other up; in accordance with the transmission of the series can be divided into single and multi-stage gear box; in accordance with the rotation of the arrangement can be divided into the expansion, diversion, and coaxial-type and mixed type and so on.HeaderThe cabinet is made of the important parts of the gearbox, which bear the reaction force generated from the force of the wind wheel and gear drive, you must have sufficient rigidity to withstand the forces and moments to prevent the deformation, to ensure the transmission quality. The cabinet design should be arranged in accordance with the layout of the wind turbine power transmission, processing and assembly conditions,to facilitate inspection and maintenance requirements to carry out. Should pay attention to the different directions of the bearing support and the base supporting the anti-force and its relative value, select the appropriate support structure and wall thickness, and the addition of the necessary ribs. The location of the tendons shall be consistent with the direction of cabinet deformation caused by force.Box stress situation is very complex and uneven distribution, only the use of modern calculation methods, such as finite element and fracture mechanics methods supplemented by photoelastic experiment simulates actual working conditions, in order to more accurately calculate the stress distribution situation. Using computer-aided design, can be obtained with the actual stress is very close to the results. Gearbox lubricationLubrication of the gear box is very important, good lubrication can serve as adequate protection for gears and bearings. Therefore, we must attach great importance to the lubrication of the gear box, and long-term in the best condition in strict accordance with specifications to maintain lubrication system. The gear box is often used splash lubrication or forced lubrication is more common, usually with forced lubrication.Therefore, with a reliable lubrication system is particularly important. Will be electric gear pump oil from the tank by the oil filter transmitted to the gear box lubrication piping, lubricating the various parts of the gear and transmission pipeline is equipped with a variety of monitoring devices to ensure that the gearbox in operation which does not appear off the oil.Lubricating oil requirements should be considered:1)reduce the friction and wear, with a high carrying capacity, to prevent the glue; 2)to absorb shock and vibration; 3) to prevent fatigue pitting; 4) cooling, rust, corrosion-resistant. Transmission of different types have differentrequirements. Wind turbine gearbox is a type of enclosed gear drives, the main form of failure is glued pitting Therefore, the choice of lubricant, the focus is to ensure adequate oil film thickness and the boundary film strength. Work in a larger temperature difference, the viscosity index is relatively high. To improve the carrying capacity and impact resistance of the gear appropriate to add some extreme pressure additives is also necessary to have some side effects, but the additives must be careful in the choice of when. The gearbox manufacturer generally recommend a variety of lubricants according to their experience or experimental studies, such as MOBIL632,MOBIL630 or L-CKC320 L-CKC220GB5903-95 gear oil is selected according to the tooth surface contact stress and the use of environmental conditions.Gear damageGear damage the impact of many factors, including material selection, design calculations, processing, heat treatment, installation and commissioning, lubrication and maintenance. Common damage of the gear tooth surface damage and tooth broken two.(A) of the tooth fracture (broken teeth)断齿常由细微裂纹逐步扩展而成。

附录C：外文翻译资料Article Source：Business & Commercial Aviation, Nov 20, 2000. 5-87-88 Interactive Electronic Technical Manuals Electronic publications can increase the efficiency of your digital aircraft and analogtechnicians.Benoff, DaveComputerized technical manuals are silently revolutionizing the aircraft maintenance industry by helping the technician isolate problems quickly, and in the process reduce downtime and costs by more than 10 percent.These electronic publications can reduce the numerous volumes of maintenance manuals, microfiche and work cards that are used to maintain engines, airframes, avionics and their associated components."As compared with the paper manuals, electronic publications give us greater detail and reduced research times," said Chuck Fredrickson, general manager of Mercury Air Center in Fort Wayne, Ind.With all the advances in computer hardware and software technologies, such as high quality digital multimedia, hypertext and the capability to store and transmit digital multimedia via CD-ROMs/ networks, technical publication companies have found an effective, cost-efficient method to disseminate data to technicians.The solution for many operators and OEMs is to take advantage of today's technology in the form of Electronic Technical Manuals (ETM) or Interactive Technical Manuals (IETM). An ETM is any technical manual prepared in digital format that has the ability to be displayed using any electronic hardware media. The difference between the types of ETM/IETMs is the embedded functionality and implementation of the data."The only drawback we had to using ETMs was getting enough computers to meet our technicians' demand," said Walter Berchtold, vice president of maintenance at Jet Aviation's West Palm Beach, Fla., facility.A growing concern is the cost to print paper publications. In an effort to reduce costs, some aircraft manufacturers are offering incentives for owners to switch from paper to electronic publications. With an average printing cost of around 10 cents per page, a typical volume of a paper technical manual can cost the manufacturer over $800 for each copy. When producing a publication electronically, average production costs for a complete set of aircraft manuals are approximately $20 per copy. It is not hard to see the cost advantages of electronic publications.Another advantage of ETMs is the ease of updating information. With a paper copy, the manufacturer has to reprint the revised pages and mail copies to all the owners. When updates are necessary for an electronic manual, changes can either be e-mailed to theowners or downloaded from the manufacturer's Web site.So why haven't more flight departments converted their publications to ETM/IETMs? The answer lies in convincing technicians that electronic publications can increase their efficiency."We had an initial learning curve when the technicians switched over, but now that they are familiar with the software they never want to go back to paper," said Fredrickson.A large majority of corporate technicians also said that while they like the concept of having a tool that aids the troubleshooting process, they are fearful to give up all of their marked-up paper manuals.In 1987, a human factors study was conducted by the U.S. government to compare technician troubleshooting effectiveness, between paper and electronic methodology, and included expert troubleshooting procedures with guidance through the events. Results of the project indicated that technicians using electronic media took less than half the time to complete their tasks than those using the paper method, and technicians using the electronic method accomplished 65 percent more in that reduced time.The report also noted that new technicians using the electronic technical manuals were 12-percent more efficient than the older, more experienced technicians. (Novices using paper took 15 percent longer than the experts.)It is interesting that 90 percent of the technicians who used the electronic manuals said they preferred them to the paper versions. This proved to the industry that with proper training, the older technicians could easily transition from paper to electronic media.Electronic publications are not a new concept, although how they are applied today is. "Research over the last 20 years has provided a solid foundation for today's IETM implementation," said Joseph Fuller of the U.S. Naval Surface Warfare Center. "IETMs such as those for the Apache, Comanche, F-22, JSTAR and V-22 have progressed from concept to military and commercial implementation."In the late 1970s, the U.S. military investigated the feasibility of converting existing paper and microfilm. The Navy Technical Information Presentation System (NTIPS) and the Air Force Computer- based Maintenance Aid System (CMAS) were implemented with significant cost savings.The report stated that transition to electronic publications resulted in reductions in corrective maintenance time, fewer false removals of good components, more accurate and complete maintenance data collection reports, reduction in training requirements and reduced system downtime.The problem that the military encountered was ETMs were created in multiple levels of complexity with little to no standardization. Options for publications range from simple page-turning programs to full-functioning automated databases.This resulted in the classification of ETMs so that the best type of electronic publication could be selected for the proper application.Choosing a LevelWith all of the OEM and second- and third-party electronic publications that are available it is important that you choose the application level that is appropriate for your operation.John J. Miller, BAE Systems' manager of electronic publications, told B/CAthat "When choosing the level of an ETM/IETM, things like complexity of the aircraft and its systems, ease of use, currency of data and commonality of data should be the deciding factors; and, of course, price. If operational and support costs are reduced when you purchase a full-functioning IETM, then you should purchase the better system."Miller is an expert on the production, sustainment and emerging technologies associated with electronic publications, and was the manager of publications for Boeing in Philadelphia.Electronic publications are classified in one of five categories. A Class 1 publication is a basic electronic "page turner" that allows you to view the maintenance manual as it was printed. With a Class 2 publication all the original text of the manual is viewed as one continuous page with no page breaks. In Class 3, 4 and 5 publications the maintenance manual is viewed on a computer in a frame-based environment with increasing options as the class changes. (See sidebar.)Choosing the appropriate ETM for your operation is typically limited to whatever is being offered on the market, but since 1991 human factors reports state the demand has increased and, therefore, options are expected to follow.ETM/IETM ProvidersCompanies that create ETM/IETMs are classified as either OEM or second party provider. Class 1, 3 and 4 ETM/IETMs are the most commonly used electronic publications for business and commercial operators and costs can range anywhere from $100 to $3,000 for each ETM/ IETM. The following are just a few examples ofETM/IETMs that are available on the market.Dassault Falcon Jet offers operatorsof the Falcon 50/50EX, 900/900EX and 2000 a Class 4 IETM called the Falcon Integrated Electronic Library by Dassault (FIELD). Produced in conjunction with Sogitec Industries in Suresnes Cedex, France, the electronic publication contains service documentation, basic wiring, recommended maintenance and TBO schedules, maintenance manual, tools manual, service bulletins, maintenance and repair manual, and avionics manual.The FIELD software allows the user to view the procedures and hot- link directly to the Illustrated parts catalog. The software also enables the user to generate discrepancy forms, quotation sheets, annotations in the manual and specific preferences for each user.BAE's Miller said most of the IETM presentation systems have features called "Technical Notes." If a user of the electronic publication notices a discrepancy or needs to annotate the manual for future troubleshooting, the user can add a Tech Note (an electronic mark-up) to the step or procedure and save it to the base document. The next time that or another user is in the procedure, clicking on the tech note icon launches a pop-up screen displaying the previous technician's comments. The same electronic transfer of tech notes can be sent to other devices by using either a docking station or through a network server. In addition, systems also can use "personal notes" similar to technical notes that are assigned ID codes that only the authoring technician can access.Requirements for the FIELD software include the minimum of a 16X CD-ROM drive,Pentium II 200 MHz computer, Windows 95, Internet Explorer 4 SP 1 and Database Access V3.5 or higher.Raytheon offers owners of Beech and Hawker aircraft a Class 4 IETM called Raytheon Electronic Publication Systems (REPS). The REPS software links the frame-based procedures with the parts catalog using a single CD-ROM.Raytheon Aircraft Technical Publications said other in- production Raytheon aircraft manual sets will be converted to the REPS format, with the goal of having all of them available by 2001. In addition Raytheon offers select Component Maintenance Manuals (CMM). The Class 1 ETM is a stand-alone "page-turner" electronic manual that utilizes the PDF format of Adobe Acrobat.Other manufacturers including Bombardier, Cessna and Gulfstream offer operators similar online and PDF documentation using a customer- accessed Web account.Boeing is one manufacturer that has developed an onboard Class 5 IETM. Called the Computerized Fault Reporting System (CFRS), it has replaced the F-15 U.S. Air Force Fault Reporting Manuals. Technologies that are currently being applied to Boeing's military system are expected to eventually become a part of the corporate environment.The CFRS system determines re-portable faults by analyzing information entered during a comprehensive aircrew debrief along with electronically recovered maintenance data from the Data Transfer Module (DTM). After debrief the technicians can review aircraft faults and schedule maintenance work to be performed. The maintenance task is assigned a Job Control Number (JCN) and is forwarded electronically to the correct work center or shop. Appropriate information is provided to the Air Force's Core Automated Maintenance System (CAMS).When a fault is reported by pilot debrief, certain aircraft systems have the fault isolation procedural data on a Portable Maintenance Aid (PMA). The JCN is selected on a hardened laptop with a wireless Local Area Network (LAN) connection to the CFRS LAN infrastructure. The Digital Wiring Data System (DWDS) displays aircraft wiring diagrams to the maintenance technician for wiring fault isolation. On completion of maintenance, the data collected is provided to the Air Force, Boeing and vendors for system analysis.Third party IETM developers such as BAE Systems and Dayton T. Brown offer OEMs the ability to subcontract out the development of Class 1 through 5 ETM/IETMs. For example, Advantext, Inc. offers PDF and IPDF Class 1 ETMs for manufacturers such as Piper and Bell Helicopters. Technical publications that are available include maintenance manuals, parts catalogs, service bulletins, wiring diagrams, service letters and interactive parts ordering forms.The difference between the PDF and IPDF version is that the IPDF version has the ability to search for text and include hyperlinks. A Class 1 ETM, when printed, is an exact reproduction of the OEM manuals, including any misspellings or errors. Minimum requirements for the Advantext technical publications is a 486 processor, 16 MB RAM with 14 MB of free hard disk space and a 4X CD-ROM or better.Aircraft Technical Publishers (ATP) offers Class 1, 2 and 3 ETM/ IETMsfor the Beechjet 400/400A; King Air 300/ 350, 200 and 90; Learjet 23/24/25/28/29/35/36/55; Socata TB9/10/20/21 and TBM 700A; Sabreliner 265-65, -70 and -80; andBeech 1900. The libraries can include maintenance manuals, Illustrated parts bulletins, wiring manuals, Airworthiness Directives, Service Bulletins, component maintenance manuals and structural maintenance manuals. System minimum requirements are Pentium 133 MHz, Windows 95 with 16 MB RAM, 25 MB free hard disk space and a 4X CD-ROM or better.Additional providers such as Galaxy Scientific are providing ETM/ IETMs to the FAA. This Class 2, 3 and 4 publication browser is used to store, display and edit documentation for the Human Factors Section of the administration."Clearly IETMs have moved from research to reality," said Fuller, and the future looks to hold more promise.The Future of Tech PubsThe use of ETM/IETMs on laptop and desktop computers has led research and development corporations to investigate the human interface options to the computer. Elements that affect how a technician can interface with a computer are the work environment, economics and ease of use. Organizations such as the Office of Naval Research have focused their efforts on the following needs of technicians: -- Adaptability to the environment.-- Ease of use.-- Improved presentation of complex system relationship.-- Maximum reuse and distribution of engineering data.-- Intelligent data access.With these factors in mind, exploratory development has begun in the areas of computer vision, augmented reality display and speech recognition.Computer vision can be created using visual feedback from a head- mounted camera. The camera identifies the relative position and orientation of an object in an observed scene, and the object is used to correlate the object with a three-dimensional model. In order for a computer vision scenario to work, engineering data has to be provided through visually compatible software.When systems such as Sogitech's View Tech electronic publication browser and Dassault Systemes SA's Enovia are combined, a virtual 3D model is generated.The digital mockup allows the engineering information to directly update the technical publication information. If a system such as CATIA could be integrated into a Video Reference System (VRS), then it could be possible that a technician would point the camera to the aircraft component, the digital model identifies the component and the IETM automatically displays the appropriate information.This example of artificial intelligence is already under development at companies like Boeing and Dassault. An augmented reality display is a concept where visual cues are presented to users on a head-mounted, see-through display system.The cues are presented to the technician based on the identification of components on a 3D model and correlation with the observed screen. The cues are then presented as stereoscopic images projected onto the object in the observed scene.In addition a "Private Eye" system could provide a miniature display of the maintenance procedure that is provided from a palm- size computer. Limited success hascurrently been seen in similar systems for the disabled. The user of a Private Eye system can look at the object selected and navigate without ever having to touch the computer. Drawbacks from this type of system are mental and eye fatigue, and spatial disorientation.Out of all the technologies, speech recognition has developed into an almost usable and effective system. The progression through maintenance procedures is driven by speaker-independent recognition. A state engine controls navigation, and launches audio responses and visual cues to the user. Voice recognition software is available, although set up and use has not been extremely successful.Looking at other industries, industrial manufacturing has already started using "Palm Pilot" personal digital assistants (PDAs) to aid technicians in troubleshooting. These devices allow the technician to have the complete publication beside them when they are in tight spaces. "It would be nice to take the electronic publications into the aircraft, so we are not constantly going back to the work station to print out additional information," said Jet Aviation's Berchtold.With all the advantages that a ETM/ IETM offers it should be noted that electronic publications are not the right solution all of the time, just as CBT is not the right solution for training in every situation. Only you can determine if electronic publications meet your needs, and most technical publication providers offer demo copies for your review.

Increasing oxygen transfer inflow by stones placed in rivers was studied by Cokgor and Kucukali(2004.Growingfloating aquatic macrophytes(Sooknah and Wilkie,2004or terrestrial green plants usingfloating supports(Li and Wu,1997,physical ecological engineering(PEEN(Pu et al.,1998,and biotic addi-tives have also been applied(Chen,2003.However,these sim-ple designs do not constitute a real water treatment system and the efficiencies of these treatments are unsatisfactory.Activated sludge systems have been proved efficient treat-ing municipal sewage since the1960s(Ray,1995.However, this type of system has not been used for in situ remediation of polluted lakes or rivers.In the present study,the oxidation ditch technique was adopted on a lake receiving municipal sewage sludge.Floating green plants and the biofilms com-prisingfloating materials and plant roots were also added to enhance N and P removal.A pilot scale experiment was set up to test the feasibility and performance of the plant-enhanced oxidation ditch for in situ treatment ofboth the municipal sewage and the polluted lake water.2.Experimental2.1.Site descriptionThe study lake was situated at South China Agricultural Uni-versity,Guangzhou,China.The area of the lake was about 10000m2and the depth0.5–3m.This lake received the munic-ipal sewage from the residential area around the university.Fig.1–Surface arrangement of the plant-biofilm oxidation ditch and the waterflows.(1Wall of nylon tissue;(2nets of5mm;(3nets of0.25mm;(4oxidation ditch;(5jet-flow aerator;(6water pump;(7floating green plants;(8sewage entry.2.2.Establishment of the plant-biofilm oxidationditchesT wo24m2(width2m,length12mparallel oxidation ditches made of plastic materials were installed along the lake bank near the sewage inlet.The inner ditch was made of cement and the outer ditch was isolated with nylon tissues andfix-ing PVC(polyvinyl chloridetubes.Fig.1showsthe surface arrangement and the waterflow path.The coarse suspended solids in the influent werefiltered by two pl astic nets,one with a pore size of5mm and the other with a pore size of0.25mm,whereas the suspended solids in the effluent werefiltered by a plastic net with a pore size of 0.25mm.Zizania caduciflora and Canna generalis were grown in the ditch with theplast icfloating supporters which held the plants in position.Thefloating supporters were made of closed126e c o l o g i c a l e n g i n e e r i n g28(2006124–130PVC tubes and nylon nets and each was3.6m2.Zizania caduci-flora was grown on twofloating supporters an d Canna gener-alis on another two supporters.The plants were planted in four columns andfive lines.The twofloating supporters with Canna generalis were near the influent and the two with Zizania caduciflora were near the effluent.The entire disposal system is shown in Photo1.2.3.Conduct of the experimentsAn experiment was conductedfirstly on municipal sewage in autumn–winter seasons of2003–2004for about150days. The aeration of the oxidation ditch was achieved using a jet-flow aerator of0.75kW(Aqua Co.,Italy;air generation10m3/h, water jet rate22–28m3/h.The water sampling started on18 September2003and

sampled every3–5days at 08:00–09:00a.m.andat17:00–18:00p.m.,each with three sam-pling re plicates for thefirst run.For the second run,the influ-ent and effluent were sampled1day a week.The water

weeks before water sampling and thefirst harvest was carried out60days later and at the termination of thefirst run for the municipal sewage.The plant biomass and N and P con-tents were measured according to the methods proposed by the Soil and Agro-Chemical Analysis Committee of China(Lu, 2000.The total uptakes of N and P were calculated and com-pared with the total removal of these elements

The oxidation ditch has been used for many years worldwide as an economical and efficient wastewater treatment technology that can remove COD, nitrogen and a fraction of the phosphorusefficiently.

Conclusions The present study adapted the oxidation ditch on the lake surface for in situ treatment of municipal sewage or polluted lake water in combination with plant biofilms for performing N and P removal, and running experiments at pilot scale for about 1.5 years resulted in the following observations: (1 The system was quite satisfactory and stable for treatment of municipal sewage and polluted lake water in removing COD, NH4 + -N and P. (2 The direct uptake of N and P by plants was negligible in comparison with the totalremoval by the system, but indirect mechanisms via plant root exudates and biofilms merit further studies. (3 The proposed process could dramatically reduce the costs of sewage collection, the land-space requirement and the construction costs compared with conventional sewage treatment plants; might be suitable for treatment of both municipal sewage and polluted lake water; and could lead to the promotion of wastewater treatment in many developing countries.

外文文献翻译原文Analysis of Con tin uous Prestressed Concrete BeamsChris BurgoyneMarch 26, 20051、IntroductionThis conference is devoted to the development of structural analysis rather than the strength of materials, but the effective use of prestressed concrete relies on an appropriate combination of structural analysis techniques with knowledge of the material behaviour. Design of prestressed concrete structures is usually left to specialists; the unwary will either make mistakes or spend inordinate time trying to extract a solution from the various equations.There are a number of fundamental differences between the behaviour of prestressed concrete and that of other materials. Structures are not unstressed when unloaded; the design space of feasible solutions is totally bounded；in hyperstatic structures, various states of self-stress can be induced by altering the cable profile, and all of these factors get influenced by creep and thermal effects. How were these problems recognised and how have they been tackled?Ever since the development of reinforced concrete by Hennebique at the end of the 19th century (Cusack 1984), it was recognised that steel and concrete could be more effectively combined if the steel was pretensioned, putting the concrete into compression. Cracking could be reduced, if not prevented altogether, which would increase stiffness and improve durability. Early attempts all failed because the initial prestress soon vanished, leaving the structure to be- have as though it was reinforced; good descriptions of these attempts are given by Leonhardt (1964) and Abeles (1964).It was Freyssineti’s observations of the sagging of the shallow arches on three bridges that he had just completed in 1927 over the River Allier near Vichy which led directly to prestressed concrete (Freyssinet 1956). Only the bridge at Boutiron survived WWII (Fig 1). Hitherto, it had been assumed that concrete had a Young’s modulus which remained fixed, but he recognised that the de- ferred strains due to creep explained why the prestress had been lost in the early trials. Freyssinet (Fig. 2) also correctly reasoned that high tensile steel had to be used, so that some prestress would remain after the creep had occurred, and alsothat high quality concrete should be used, since this minimised the total amount of creep. The history of Freyssineti’s early prestressed concrete work is written elsewhereFigure1:Boutiron Bridge,Vic h yFigure 2: Eugen FreyssinetAt about the same time work was underway on creep at the BRE laboratory in England ((Glanville 1930) and (1933)). It is debatable which man should be given credit for the discovery of creep but Freyssinet clearly gets the credit for successfully using the knowledge to prestress concrete.There are still problems associated with understanding how prestressed concrete works, partly because there is more than one way of thinking about it. These different philosophies are to some extent contradictory, and certainly confusing to the young engineer. It is also reflected, to a certain extent, in the various codes of practice.Permissible stress design philosophy sees prestressed concrete as a way of avoiding cracking by eliminating tensile stresses; the objective is for sufficient compression to remain after creep losses. Untensionedreinforcement, which attracts prestress due to creep, is anathema. This philosophy derives directly from Freyssinet’s logic and is primarily a working stress concept.Ultimate strength philosophy sees prestressing as a way of utilising high tensile steel as reinforcement. High strength steels have high elastic strain capacity, which could not be utilised when used as reinforcement; if the steel is pretensioned, much of that strain capacity is taken out before bonding the steel to the concrete. Structures designed this way are normally designed to be in compression everywhere under permanent loads, but allowed to crack under high live load. The idea derives directly from the work of Dischinger (1936) and his work on the bridge at Aue in 1939 (Schonberg and Fichter 1939), as well as that of Finsterwalder (1939). It is primarily an ultimate load concept. The idea of partial prestressing derives from these ideas.The Load-Balancing philosophy, introduced by T.Y. Lin, uses prestressing to counter the effect of the permanent loads (Lin 1963). The sag of the cables causes an upward force on the beam, which counteracts the load on the beam. Clearly, only one load can be balanced, but if this is taken as the total dead weight, then under that load the beam will perceive only the net axial prestress and will have no tendency to creep up or down.These three philosophies all have their champions, and heated debates take place between them as to which is the most fundamental.2、Section designFrom the outset it was recognised that prestressed concrete has to be checked at both the working load and the ultimate load. For steel structures, and those made from reinforced concrete, there is a fairly direct relationship between the load capacity under an allowable stress design, and that at the ultimate load under an ultimate strength design. Older codes were based on permissible stresses at the working load; new codes use moment capacities at the ultimate load. Different load factors are used in the two codes, but a structure which passes one code is likely to be acceptable under the other.For prestressed concrete, those ideas do not hold, since the structure is highly stressed, even when unloaded. A small increase of load can cause some stress limits to be breached, while a large increase in load might be needed to cross other limits. The designer has considerable freedom to vary both the working load and ultimate load capacities independently; both need to be checked.A designer normally has to check the tensile and compressive stresses, in both the top and bottom fibre of the section, for every load case. The critical sections are normally, but not always, the mid-span and the sections over piers but other sections may become critical ，when the cable profile has to be determined.The stresses at any position are made up of three components, one of which normally has a different sign from the other two; consistency of sign convention is essential.If P is the prestressing force and e its eccentricity, A and Z are the area of the cross-section and its elastic section modulus, while M is the applied moment, then where ft and fc are the permissible stresses in tension and compression.c e t f ZM Z P A P f ≤-+≤Thus, for any combination of P and M , the designer already has four in- equalities to deal with.The prestressing force differs over time, due to creep losses, and a designer isusually faced with at least three combinations of prestressing force and moment;• the applied moment at the time the prestress is first applied, before creep losses occur,• the maximum applied moment after creep losses, and• the minimum applied moment after creep losses.Figure 4: Gustave MagnelOther combinations may be needed in more complex cases. There are at least twelve inequalities that have to be satisfied at any cross-section, but since an I-section can be defined by six variables, and two are needed to define the prestress, the problem is over-specified and it is not immediately obvious which conditions are superfluous. In the hands of inexperienced engineers, the design process can be very long-winded. However, it is possible to separate out the design of the cross-section from the design of the prestress. By considering pairs of stress limits on the same fibre, but for different load cases, the effects of the prestress can be eliminated, leaving expressions of the form:rangestress e Perm issibl Range Mom entZ These inequalities, which can be evaluated exhaustively with little difficulty, allow the minimum size of the cross-section to be determined.Once a suitable cross-section has been found, the prestress can be designed using a construction due to Magnel (Fig.4). The stress limits can all be rearranged into the form:()M fZ PA Z e ++-≤1 By plotting these on a diagram of eccentricity versus the reciprocal of the prestressing force, a series of bound lines will be formed. Provided the inequalities (2) are satisfied, these bound lines will always leave a zone showing all feasible combinations of P and e. The most economical design, using the minimum prestress, usually lies on the right hand side of the diagram, where the design is limited by the permissible tensile stresses.Plotting the eccentricity on the vertical axis allows direct comparison with the crosssection, as shown in Fig. 5. Inequalities (3) make no reference to the physical dimensions of the structure, but these practical cover limits can be shown as wellA good designer knows how changes to the design and the loadings alter the Magnel diagram. Changing both the maximum andminimum bending moments, but keeping the range the same, raises and lowers the feasible region. If the moments become more sagging the feasible region gets lower in the beam.In general, as spans increase, the dead load moments increase in proportion to the live load. A stage will be reached where the economic point (A on Fig.5) moves outside the physical limits of the beam; Guyon (1951a) denoted the limiting condition as the critical span. Shorter spans will be governed by tensile stresses in the two extreme fibres, while longer spans will be governed by the limiting eccentricity and tensile stresses in the bottom fibre. However, it does not take a large increase in moment ，at which point compressive stresses will govern in the bottom fibre under maximum moment.Only when much longer spans are required, and the feasible region moves as far down as possible, does the structure become governed by compressive stresses in both fibres.3、Continuous beamsThe design of statically determinate beams is relatively straightforward; the engineer can work on the basis of the design of individual cross-sections, as outlined above. A number of complications arise when the structure is indeterminate which means that the designer has to consider, not only a critical section,but also the behaviour of the beam as a whole. These are due to the interaction of a number of factors, such as Creep, Temperature effects and Construction Sequence effects. It is the development of these ideas whichforms the core of this paper. The problems of continuity were addressed at a conference in London (Andrew and Witt 1951). The basic principles, and nomenclature, were already in use, but to modern eyes concentration on hand analysis techniques was unusual, and one of the principle concerns seems to have been the difficulty of estimating losses of prestressing force.3.1 Secondary MomentsA prestressing cable in a beam causes the structure to deflect. Unlike the statically determinate beam, where this motion is unrestrained, the movement causes a redistribution of the support reactions which in turn induces additional moments. These are often termed Secondary Moments, but they are not always small, or Parasitic Moments, but they are not always bad.Freyssinet’s bridge across the Marne at Luzancy, started in 1941 but not completed until 1946, is often thought of as a simply supported beam, but it was actually built as a two-hinged arch (Harris 1986), with support reactions adjusted by means of flat jacks and wedges which were later grouted-in (Fig.6). The same principles were applied in the later and larger beams built over the same river.Magnel built the first indeterminate beam bridge at Sclayn, in Belgium (Fig.7) in 1946. The cables are virtually straight, but he adjusted the deck profile so that the cables were close to the soffit near mid-span. Even with straight cables the sagging secondary momentsare large; about 50% of the hogging moment at the central support caused by dead and live load.The secondary moments cannot be found until the profile is known but the cablecannot be designed until the secondary moments are known. Guyon (1951b) introduced the concept of the concordant profile, which is a profile that causes no secondary moments; es and ep thus coincide. Any line of thrust is itself a concordant profile.The designer is then faced with a slightly simpler problem; a cable profile has to be chosen which not only satisfies the eccentricity limits (3) but is also concordant. That in itself is not a trivial operation, but is helped by the fact that the bending moment diagram that results from any load applied to a beam will itself be a concordant profile for a cable of constant force. Such loads are termed notional loads to distinguish them from the real loads on the structure. Superposition can be used to progressively build up a set of notional loads whose bending moment diagram gives the desired concordant profile.3.2 Temperature effectsTemperature variations apply to all structures but the effect on prestressed concrete beams can be more pronounced than in other structures. The temperature profile through the depth of a beam (Emerson 1973) can be split into three components for the purposes of calculation (Hambly 1991). The first causes a longitudinal expansion, which is normally released by the articulation of the structure; the second causes curvature which leads to deflection in all beams and reactant moments in continuous beams, while the third causes a set of self-equilibrating set of stresses across the cross-section.The reactant moments can be calculated and allowed-for, but it is the self- equilibrating stresses that cause the main problems for prestressed concrete beams. These beams normally have high thermal mass which means that daily temperature variations do not penetrate to the core of the structure. The result is a very non-uniform temperature distribution across the depth which in turn leads to significant self-equilibrating stresses. If the core of the structure is warm, while the surface is cool, such as at night, then quite large tensile stresses can be developed on the top and bottom surfaces. However, they only penetrate a very short distance into the concrete and the potential crack width is very small. It can be very expensive to overcome the tensile stress by changing the section or the prestress。

外文原文(一)Savigny and his Anglo-American Disciple s*M. H. HoeflichFriedrich Carl von Savigny, nobleman, law reformer, champion of the revived German professoriate, and founder of the Historical School of jurisprudence, not only helped to revolutionize the study of law and legal institutions in Germany and in other civil law countries, but also exercised a profound influence on many of the most creative jurists and legal scholars in England and the United States. Nevertheless, tracing the influence of an individual is always a difficult task. It is especially difficult as regards Savigny and the approach to law and legal sources propounded by the Historical School. This difficulty arises, in part, because Savigny was not alone in adopting this approach. Hugo, for instance, espoused quite similar ideas in Germany; George Long echoed many of these concepts in England during the 1850s, and, of course, Sir Henry Sumner Maine also espoused many of these same concepts central to historical jurisprudence in England in the 1860s and 1870s. Thus, when one looks at the doctrinal writings of British and American jurists and legal scholars in the period before 1875, it is often impossible to say with any certainty that a particular idea which sounds very much the sort of thing that might, indeed, have been derived from Savigny's works, was, in fact, so derived. It is possible, nevertheless, to trace much of the influence of Savigny and his legal writings in the United States and in Great Britain during this period with some certainty because so great was his fame and so great was the respect accorded to his published work that explicit references to him and to his work abound in the doctrinal writing of this period, as well as in actual law cases in the courts. Thus, Max Gutzwiller, in his classic study Der einfluss Savignys auf die Entwicklung des International privatrechts, was able to show how Savigny's ideas on conflict of laws influenced such English and American scholars as Story, Phillimore, Burge, and Dicey. Similarly, Andreas Schwarz, in his "Einflusse Deutscher Zivilistik im Auslande," briefly sketched Savigny's influence upon John Austin, Frederick Pollock, and James Bryce. In this article I wish to examine Savigny's influence over a broader spectrum and to draw a picture of his general fame and reputation both in Britain and in the United States as the leading Romanist, legal historian, and German legal academic of his day. The picture of this Anglo-American respect accorded to Savigny and the historical school of jurisprudence which emerges from these sources is fascinating. It sheds light not only upon Savigny’s trans-channel, trans-Atlantic fame, but also upon the extraordinarily*M.H.Hoeflich, Savigny and his Anglo-American Disciples, American Journal of Comparative Law, vol.37, No.1, 1989.cosmopolitan outlook of many of the leading American and English jurists of the time. Of course, when one sets out to trace the influence of a particular individual and his work, it is necessary to demonstrate, if possible, precisely how knowledge of the man and his work was transmitted. In the case of Savigny and his work on Roman law and ideas of historical jurisprudence, there were three principal modes of transmission. First, there was the direct influence he exercised through his contacts with American lawyers and scholars. Second, there was the influence he exercised through his books. Third, there was the influence he exerted indirectly through intermediate scholars and their works. Let us examine each mode separately.I.INFLUENCE OF THE TRANSLATED WORKSWhile American and British interest in German legal scholarship was high in the antebellum period, the number of American and English jurists who could read German fluently was relatively low. Even those who borrowed from the Germans, for instance, Joseph Story, most often had to depend upon translations. It is thus quite important that Savigny’s works were amongst the most frequently translated into English, both in the United States and in Great Britain. His most influential early work, the Vom Beruf unserer Zeitfur Rechtsgeschichte und Gestzgebung, was translated into English by Abraham Hayward and published in London in 1831. Two years earlier the first volume of his History of Roman Law in the Middle Ages was translated by Cathcart and published in Edinburgh. In 1830, as well, a French translation was published at Paris. Sir Erskine Perry's translation of Savigny's Treatise on Possession was published in London in 1848. This was followed by Archibald Brown's epitome of the treatise on possession in 1872 and Rattigan's translation of the second volume of the System as Jural Relations or the Law of Persons in 1884. Guthrie published a translation of the seventh volume of the System as Private International Law at Edinburgh in 1869. Indeed, two English translations were even published in the far flung corners of the British Raj. A translation of the first volume of the System was published by William Holloway at Madras in 1867 and the volume on possession was translated by Kelleher and published at Calcutta in 1888. Thus, the determined English-speaking scholar had ample access to Savigny's works throughout the nineteenth century.Equally important for the dissemination of Savigny's ideas were those books and articles published in English that explained and analyzed his works. A number of these must have played an important role in this process. One of the earliest of these is John Reddie's Historical Notices of the Roman law and of the Progress of its Study in Germany, published at Edinburgh in 1826. Reddie was a noted Scots jurist and held the Gottingen J.U.D. The book, significantly, is dedicated to Gustav Hugo. It is of that genre known as an external history of Roman law-not so much a history of substantive Roman legal doctrine but rather a historyof Roman legal institutions and of the study of Roman law from antiquity through the nineteenth century. It is very much a polemic for the study of Roman law and for the Historical School. It imparts to the reader the excitement of Savigny and his followers about the study of law historically and it is clear that no reader of the work could possibly be left unmoved. It is, in short, the first work of public relations in English on behalf of Savigny and his ideas.Having mentioned Reddie's promotion of Savigny and the Historical School, it is important to understand the level of excitement with which things Roman and especially Roman law were greeted during this period. Many of the finest American jurists were attracted-to use Peter Stein's term-to Roman and Civil law, but attracted in a way that, at times, seems to have been more enthusiastic than intellectual. Similarly, Roman and Civil law excited much interest in Great Britain, as illustrated by the distinctly Roman influence to be found in the work of John Austin. The attraction of Roman and Civil law can be illustrated and best understood, perhaps, in the context of the publicity and excitement in the English-speaking world surrounding the discovery of the only complete manuscript of the classical Roman jurist Gaius' Institutes in Italy in 1816 by the ancient historian and German consul at Rome, B.G. Niebuhr. Niebuhr, the greatest ancient historian of his time, turned to Savigny for help with the Gaius manuscript (indeed, it was Savigny who recognized the manuscript for what it was) and, almost immediately, the books and journals-not just law journals by any means-were filled with accounts of the discovery, its importance to legal historical studies, and, of course, what it said. For instance, the second volume of the American Jurist contains a long article on the civil law by the scholarly Boston lawyer and classicist, John Pickering. The first quarter of the article is a gushing account of the discovery and first publication of the Gaius manuscript and a paean to Niebuhr and Savigny for their role in this. Similarly, in an article published in the London Law Magazine in 1829 on the civil law, the author contemptuously refers to a certain professor who continued to tell his students that the text of Gaius' Institutes was lost for all time. What could better show his ignorance of all things legal and literary than to be unaware of Niebuhr's great discovery?Another example of this reaction to the discovery of the Gaius palimpsest is to be found in David Irving's Introduction to the Study of the Civil Law. This volume is also more a history of Roman legal scholarship and sources than a study of substantive Roman law. Its pages are filled with references to Savigny's Geschichte and its approach clearly reflects the influence of the Historical School. Indeed, Irving speaks of Savigny's work as "one of the most remarkable productions of the age." He must have been truly impressed with German scholarship and must also have been able to convince the Faculty of Advocates, forwhom he was librarian, of the worth of German scholarship, for in 1820 the Faculty sent him to Gottingen so that he might study their law libraries. Irving devotes several pages of his elementary textbook on Roman law to the praise of the "remarkable" discovery of the Gaius palimpsest. He traces the discovery of the text by Niebuhr and Savigny in language that would have befitted an adventure tale. He elaborates on the various labors required to produce a new edition of the text and was particularly impressed by the use of a then new chemical process to make the under text of the palimpsest visible. He speaks of the reception of the new text as being greeted with "ardor and exultation" strong words for those who spend their lives amidst the "musty tomes" of the Roman law.This excitement over the Verona Gaius is really rather strange. Much of the substance of the Gaius text was already known to legal historians and civil lawyers from its incorporation into Justinian's Institutes and so, from a substantive legal perspective, the find was not crucial. The Gaius did provide new information on Roman procedural rules and it did also provide additional information for those scholars attempting to reconstruct pre-Justinianic Roman law. Nevertheless, these contributions alone seem hardly able to justify the excitement the discovery caused. Instead, I think that the Verona Gaius discovery simply hit a chord in the literary and legal community much the same as did the discovery of the Rosetta Stone or of Schliemann’s Troy. Here was a monument of a great civilization brought newly to light and able to be read for the first time in millenia. And just as the Rosetta Stone helped to establish the modern discipline of Egyptology and Schliemann's discoveries assured the development of classical archaeology as a modern academic discipline, the discovery of the Verona Gaius added to the attraction Roman law held for scholars and for lawyers, even amongst those who were not Romanists by profession. Ancillary to this, the discovery and publication of the Gaius manuscript also added to the fame of the two principals involved in the discovery, Niebuhr and Savigny. What this meant in the English-speaking world is that even those who could not or did not wish to read Savigny's technical works knew of him as one of the discoverers of the Gaius text. This fame itself may well have helped in spreading Savigny's legal and philosophical ideas, for, I would suggest, the Gaius "connection" may well have disposed people to read other of Savigny's writings, unconnected to the Gaius, because they were already familiar with his name.Another example of an English-speaking promoter of Savigny is Luther Stearns Cushing, a noted Boston lawyer who lectured on Roman law at the Harvard Law School in 1848-49 and again in 1851- 1852.Cushing published his lectures at Boston in 1854 under the title An Introduction to the Study of Roman Law. He devoted a full chapter to a description of the historical school and to the controversy betweenSavigny and Thibaut over codification. While Cushing attempted to portray fairly the arguments of both sides, he left no doubt as to his preference for Savigny's approach:The labors of the historical school have established an entirely new and distinct era in the study of the Roman jurisprudence; and though these writers cannot be said to have thrown their predecessors into the shade, it seems to be generally admitted, that almost every branch of the Roman law has received some important modification at their hands, and that a knowledge of their writings, to some extent, at least, is essentially necessary to its acquisition.译文(一)萨维尼和他的英美信徒们*M·H·豪弗里奇弗雷德里奇·卡尔·冯·萨维尼出身贵族，是一位出色的法律改革家，也是一位倡导重建德国教授协会的拥护者，还是历史法学派的创建人之一。

Project Management ProcessDurgesh BurdeAbstract:There are the rules of project management. Project management skills are indispensable for project managers, and other managers who control intricate actions and responsibilities, because intricate responsibilities are projects. Project management skills are necessary for any intricate responsibility, where diverse results are feasible, requiring plan and assess alternatives, and organizing actions and assets to deliver an outcome. Projects arrive in all forms and dimensions, from the little and simple to extremely big and highly intricate. Project management may be concerned with everything such as:- public, products, finance, buildings and premises, acquisition, services, purchasing, resources, construction, plant and equipment, training, culture, divestment, storage, distribution, logistics, IT and communications, staffing and management, administration, sales, selling, marketing, human resources, etc. Project management, for projects large or small, should follow the simple process:Project management process1.Detailed requirement for the project.2.Plan the project - time, team, activities, resources, and financials.3.Correspond the project plan to the project group.4.Consent and allot project actions.5.Control, encourage, notify, promote, and facilitate the project team.6.Verify, assess, evaluate project development; regulate project procedure, andnotify the project members and others.7.Finish project; evaluation and report on project performance; Admire and thanksto the project members.1. Detailed requirement for the projectFrequently called the project 'terms of reference', the project requirement should be an exact depiction of what the project aspires to accomplish, and the criteria and flexibilities concerned, its factors, scope, range, outputs, sources, participants, budgets and timescales.The project manager must discuss with others and then consent the project requirement with superiors, or with relevant authorities. The requirement may engage several drafts before it is agreed. A project requirement is essential in that it creates a measurable accountability for anyone wishing at any time to assess how the project is going, or its success on completion. Project terms of reference also provide an essential discipline and framework to keep the project on track, and concerned with the original agreed aims and parameters. A properly formulated and agreed project requirement also protects the project manager from being held to account for issues that are outside the original scope of the project or beyond the project manager's control.This is the step to agree special circumstances or exceptions with those in authority. Once you have published the terms of reference you have created a very firm set of expectations by which you will be judged. So if you have any concerns, or want to renegotiate, now's the time to do it.The largest projects can require several weeks to produce and agree project terms of reference. Most normal business projects however require a few days thinking and consulting to produce a suitable project requirement. Establishing and agreeing a project requirement is an important process even if your task is simple one.An outline for a project requirement:1.Describe purpose, aims and deliverables.2.State factors (timescales, budgets, range, scope, territory, authority).3.State people involved and the way the team will work (frequency of meetings,decision-making process).4.Establish 'break-points' at which to review and check progress, and how progressand results will be measured.2. Plan the project - time, team, activities, resources, and financials.Plan the various steps and tasks of the project. A valuable tip is to work backwards from the end aim, identifying all the things that need to be put in place and done, in reverse order. First, idea generation will help to gather most of the points and issues. For complex projects, or when you lack experience of the issues, involve others in the idea generation process. Thereafter it is a question of putting the issues in the right order, and establishing relationships and links between each issue. Complex projects will have a number of tasks running in parallel. Some parts of the project will need other parts of the project to be completed before they can begin or progress. Some projects will require a feasibility step before the completion of a detailed plan.a) Project timescalesMost projects come in late - that is just the way it is - so do not plan a timescale that is over-ambitious. Preferably, plan for some adversaries. If you have been given a fixed deadline, plan to meet it earlier, and work back from that earlier date. Build some slippage or leeway into each phase of the project. Err on the side of caution where you can. Otherwise, you will be making a rod for your own back.b) The project teamAnother important part of the planning stage is picking your team. Take great care, especially if you have team-members imposed on you by the project brief. Selecting and gaining commitment from the best team members - whether directly employed, freelance, contractors, suppliers, consultants or other partners - is crucial to the quality of the project, and the ease with which you are able to manage it. Generally try to establish yourteam as soon as possible. Identifying or appointing one or two people even during the terms of reference stage is possible sometimes. Appointing the team early maximizes their ownership and buy-in to the project, and maximizes what they can contribute. But be very cautious of appointing people before you are sure how good they are, and not until they have committed themselves to the project upon terms that are clearly understood and acceptable. Do not imagine that teams need to be full of paid and official project team members. Some of the most valuable team members are informal advisors, mentors, helpers, who want nothing other than to be involved and a few words of thanks. Project management on a tight budget can be a lonely business - get some help from good people you can trust, whatever the budget.To plan and manage large complex projects with various parallel and dependent tasks you will need to put together a 'Critical Path Analysis' and a spreadsheet on MS Excel or equivalent. Critical Path Analysis will show you the order in which tasks must be performed, and the relative importance of tasks. Some tasks can appear small and insignificant when they might actually be hugely influential in enabling much bigger activities to proceed or give best results. A Gantt chart is a useful way of showing blocks of activities over time, at a given cost, and for managing the project and its costs along the way.Various project management software is available, much of which is useful, but before trying it, you should understand and concentrate on developing the pure project management skills, which are described in this process. The best software in the world will not help you if you cannot do the key things.c) The project 'critical path analysis''Critical Path Analysis' sounds very complicated, but it's a very logical and effective method for planning and managing complex projects. This is how to create a critical path analysis. As an example, the project is a simple one - making a fried breakfast.First note down all the issues (resources and activities in a rough order):Assemble crockery and utensils, assemble ingredients, prepare equipment, make toast, fry sausages and eggs, grill bacon and tomatoes, lay table, warm plates, serve.Note that some of these activities must happen in parallel. That is to say, if you tried to make a fried breakfast by doing one task at a time, and one after the other, things would go wrong. Certain tasks must be started before others, and certain tasks must be completed in order for others to begin. The plates need to be warming while other activities are going on. The toast needs to be toasting while the sausages are frying, and at the same time the bacon and sausages are under the grill. The eggs need to be fried last. A critical path analysis is a diagrammatical representation of what needs done and when. Timescales and costs can be applied to each activity and resource. Here's the critical path analysis for making a fried breakfast:This critical path analysis example below shows just a few activities over a few minutes. Normal business projects would see the analysis extending several times wider than this example, and the time line would be based on weeks or months. It is possible to use MS Excel or a similar spreadsheet to create a critical path analysis, which allows financial totals and time totals to be planned and tracked. Various specialized project management software enable the same thing. Beware however of spending weeks on the intricacies of computer modeling, when in the early stages especially, a carefully hand drawn diagram - which requires no computer training at all - can put 90% of the thinking and structure in place.d) Gantt chartsGantt Charts are extremely useful project management tools. You can construct a Gantt Chart using MSExcel or a similar spreadsheet. Every activity has a separate line. Create a time-line for the duration of the project (the breakfast example shows minutes, but normally you would use weeks, or for very big long-term projects, months). You can colour code the time blocks to denote type of activity (e.g. intense, watching brief, directly managed, delegated and left to run, etc.) You can schedule review and break points. At the end of each line you can show as many cost columns for the activities as you need. The breakfast example shows just the capital cost of the consumable items and a revenue cost for labour and fuel. A Gantt chart like this can be used to keep track of progress for each activity and how the costs are running. You can move the time blocks around to report on actuals versus planned, and to re-schedule, and to create new plan updates. Costs columns can show plan and actuals and variances, and calculate whatever totals, averages, ratios, etc you need. Gantt Charts are the most flexible and useful of all project management tools, but remember they do not show the importance and inter-dependence of related parallel activities, and they will not show the necessity to complete one task before another can begin, as a critical path analysis will do, so you need both tools, especially at the planning stage.e) Project financial planning and reportingFor projects, involving more than petty cash you will need a spreadsheet to plan and report planned and actual expenditure. Use MSExcel or similar. If you do not know how to put together a basic financial plan, get some help from someone who knows. Make sure you bring a good friendly, flexible financial person into your team - it is a key function of project management, and if you cannot manage the financial processes your self, you need to be able to rely completely on whoever does it for you. The spreadsheet must enable you to plan, administer and report the detailed finances of your project. Create a cost line for main expenditure activity, and break this down into individual elements. Create a system for allocating incoming invoices to the correct activities (your bought-ledger people will not know unless you tell them), and showing when the costs hit the project account. Establish clear payment terms with all suppliers and stick to them. Projects develop problems when team members get dissatisfied; rest assured, non- or late-payment is a primary cause of dissatisfaction.Remember to set some budget aside for 'contingencies' - you will need it.f) Project contingency planningPlanning for and anticipating the unforeseen, or the possibility that things may not go as expected, is called 'contingency planning'. Contingency planning is vital in any task when results and outcomes cannot be absolutely guaranteed. Often a contingency budget needs to be planned, as there are usually costs associated. Contingency planning is about preparing fallback actions, and making sure that leeway for time, activity and resource exists to rectify or replace first-choice plans. A simple contingency plan for the fried breakfast would be to plan for the possibility of breaking the yolk of an egg, in which case spare resource (eggs) should be budgeted for and available if needed. Another might be to prepare some hash browns and mushrooms in the event that any of the diners are vegetarian. It may be difficult to anticipate precisely what contingency to plan for in complex long-term projects, in which case simply a contingency budget is provided, to be allocated later when and if required.3. Correspond the project plan to the project group.This serves two purposes: it informs people what is happening, and it obtains essential support, agreement and commitment. If your project is complex and involves a team, then you should involve the team in the planning process to maximize buy-in, ownership, and thereby accountability. Your project will also benefit from input and consultation from relevant people at an early stage.4. Consent and allot project actions.Your plan will have identified those responsible for each activity. Activities need to be very clearly described, including all relevant parameters, timescales, costs, and deliverables. When delegated tasks fail this is typically because they have not been explained clearly, agreed with the other person, or supported and checked while in progress. So publish the full plan to all in the team, but do not issue all the tasks unless the recipients are capable of their own forward planning. Long-term complex projects need to be planned in more detail and great care must be taken in delegating and supporting them. Do not delegate anything unless it makes sure for perfection.5. Control, encourage, notify, promote, and facilitate the project team.Manage the team and activities by meeting, communicating, supporting, and helping with decisions. Admire vociferously; charge quietly. One of the big challenges for a project manager is deciding how much freedom to give for each delegated activity. Tight parameters and lots of checking are necessary for inexperienced people who like clear instructions, but this approach is the kiss of death to experienced, entrepreneurial and creative people. They need a wider brief, more freedom, and less checking. Manage these people by the results they get - not how they get them. Look out for differences in personality and working styles in your team. They can get in the way of understandingand cooperation. Your role here is to enable and translate. Face to face meetings, when you can bring team members together, are generally the best way to avoid issues and relationships becoming personalized and emotional. Communicate progress and successes regularly to everyone. Give the people in your team the applause, particularly when someone high up expresses satisfaction - You must take the blame for anything that goes wrong - never dump on anyone in your team.6. Verify, assess, evaluate project development; regulate project procedure, and notify the project members and others.Check the progress of activities against the plan. Review performance regularly and at the stipulated review points, and confirm the validity and relevance of the remainder of the plan. Adjust the plan if necessary in light of performance, changing circumstances, and new information, but remain on track and within the original terms of reference. Be sure to use transparent, pre-agreed measurements when judging performance. Identify, agree and delegate new actions as appropriate. Inform team members and those in authority about developments, clearly, concisely and in writing. Plan team review meetings. Stick to the monitoring systems you established. Probe the apparent situations to get at the real facts. Examine causes and learn from mistakes. Identify reliable advisors and experts in the team and use them. Keep talking to people, and make yourself available to all.7. Finish project; evaluation and report on project performance; Admire and thanks to the project members.At the end of your successful project, hold a review with the team. Ensure you understand what happened and why. Replicate on any failures and mistakes positively, objectively, and without allocating personal blame. Reflect on successes gratefully and realistically. Write a review report, and make observations and recommendations about follow up issues and priorities - there will be plenty.As project manager, to be at the end of a project and to report that the project plan has been fully met, on time and on budget, is a significant achievement, whatever the project size and complexity. The mix of skills required is such that good project managers can manage anything.Conclusions:Businesses sometimes use formal systems development processes. These help assure that systems are developed successfully. A formal process is more effective in creating strong controls, and auditors should review this process to confirm that it is well designed and is followed in practice. A good formal systems development plan outlines: • A strategy to align development with the organization’s broader objectives•Standards for new systems•Project management policies for timing and budgeting•Procedures describing the processRegardless of the methodology used, the project development process will have the same above major stages: requirement for the project, Plan the project, project group, project actions, project team, evaluate project development, regulate project procedure and finish project; evaluation and report on project performance; Admire and thanks to the project members.References:1.Project Management Guidebook2.How to Manage Projects, Priorites and Deadlines3.Project Manager Today, January 2008.4.The Big Project, July 2008.<><><><><><><><><><><><><><><><>><><><><><><>><><><><><><><><> © Durgesh Burde.

就像《职来职往》节目口号中说的那样，相信《职来职往》也会前途宽广的！2准确的嘉宾策划2.1求职嘉宾彰显个性魅力随着节目收视率的提高，节目组对于求职者的选择也呈现出多样化的趋势。
从过去播出的节目中不难看出，几乎每一期的5位求职者都各具特色，既有高学历的名牌高校在校生和拿着洋学历的海归，也有老实厚道的技术工人，有不愿接受父母安排而出门奋斗的“富二代”，也有住地下室吃馒头咸菜的“北漂”，甚至还有久未出门工作的家庭妇女和退居二线再就业的老阿姨等等。
这些人物本身就有巨大的话题性，加上节目模式决定了其娱乐成分大大增加：脚踏实地、眼高手低、狂妄自大、过分谦卑……形形色色的求职心态将原生态呈现在观众面前。
这样的嘉宾设置，改变了以往求职节目中“参与者多是高学历，对职位要求十分苛刻，观众只能是“看客”的局面。
而在《职来职往》智联招聘的网站上开通了报名专区，是求职者只需通过上网便可获得由行业达人进行职场点评的机会，大大降低了参与者的门槛，不限年龄和学历，不仅扩大了受众群，而且增加了节目讨论的话题范围。
[5]通过不同的求职者所带来的不同话题，引发大家对社会现实的思考、讨论和对自身的反思与再定位。
2.2 职场达人高调助阵节目中站在台上的18位“面试官”，也就是主持人李响口中的“职场达人”，都是节目组精心挑选和安排的，涵盖了销售、行政、人力资源、策划、设计等多个行业、其中不乏一些青春靓丽的“80”精英。
据节目制片人马浚益介绍，“对于面试官的标准，除了要求其具有个人魅力之外，更重要的是能受到观众欢迎”。
确实，我们在荧屏上看到了职场达人们，除了在自己职业领域里身经百战外，更能用犀利的眼光全面扫描求职者的缺点，并一针见血的指出，发表独到的观点，具有鲜明的个人特色。
如美国红帽软件公司的郑艳、北京新东方教育科技有限公司的唐宁，已经在观众中拥有了不少的粉丝。
还有北京天启一方广告公司媒体部总监马丁，因在节目的曝光，他的微博粉丝已经增加到了5万，还特别成立了“马丁帮帮忙”微博粉丝群，每天都要花上3个小时专门回答青年人的求职困惑。
可见，他们的出现极大的改变了大家对于以往求职节目中面试官的传统印象。
3专业的节目流程及形式策划3.1 采用“真人秀”的表现形式，强调“平民化”以往的求职节目因为收视率的考虑，在选手的选择上都有着特殊性的要求。
这就使得节目自身与普通人有着很大的差距，其真实性和服务性就得不到彰显。
[6]在《职来职往》的舞台上，参与者完全是常态表演。
他们没有光鲜亮丽的外表，没有名利驱使的企图心，他们与电视荧屏前的观众没有区别，都是普通的求职者。
他们参与节目，是为了切身体验职场压力，为自己的职业梦想而努力。
他们与行业达人就当下热点话题进行激励碰撞，节目从真实、客观、全面的角度来展现职场风貌。
由于他们和观众之间拥有相似的社会角色、经济状况、生活状况，因而更能增强观众的心理认同感和体验感。
作家王海鴒在看过一期节目后说道：“沉静、有力量、有信息，作为作者我从中看到了真实地人生百态[7]。
”3.2 节目规则有趣，并设有悬念《职来职往》节目一期90分钟左右，有五位求职者要为自己的梦想一搏，采用“环环相扣、节节过关”的真人秀形式。
一个求职者面对18个来自不同行业的面试官进行问答，根据获得认可人数的多少获得相应不同的职位，9名以上可以自己挑选百家企业就职，9名以下就只能从在场对自己感兴趣的面试官的企业中挑选，全部灭灯者则淘汰，这样的规则设置很有意思体现了娱乐性元素。
节目的整个求职过程将悬念运用其中，不仅提升了观众对节目的兴趣度，而且烘托了求职现场的气氛。
在《职来职往》设有三层悬念，第一层悬念设置是每个求职者最终能否求职成功；第二层悬念设置是选手获得的百强企业里是自我选择的职位还是现场达人所提供的较为被动的职位；第三层悬念是一种贯穿于始末的悬念，在每位求职者所要面对的四大环节约15分钟的时间里，什么时候会被行业达人灭掉代表求职机会的灯以及多少盏灯被灭掉。
这三层悬念一直统领着整个求职的过程，每一个悬念的铺设都成为求职者职业能力的鉴定，为求职者自身的求职期盼设置了悬念，也为观众对于结果的猜测设置了悬念。
《职来职往》制造的这种悬念，既推动了求职过程，也体现了电视节目应带给观众的实用性和观赏性。
[8]3.3 节目采用视频简历，突出了影视手段，传达了大量信息《职来职往》中采用影视手段——视频简历，既展示了求职者的职业理想和人生经历，又有故事情节和情感内容，更容易引起观众的共鸣。
3.4 节目整体包装，媒介融合参与《职来职往》的成功在于节目包装、宣传娴熟、大气时尚的舞台与灯光使节目“新锐式”的特色一览无余，细节处也十分考究。
达人介绍、求职者登场应聘失败或成功时，背景音乐《That is not my name》、《All We Are Ever Known》、《想飞越》、《隐形的翅膀》、《我相信》等都准确诠释了不同的节目气氛，歌曲的网络点击率随即攀升[9]。
其中在《我相信》中透过感人歌词向外界坦露求职者一路走来的心路历程，而《隐形的翅膀》是一首国民励志歌曲，给求职者一种人生鼓励。
制作优良的《职来职往》浅层次带给求职者经验教训，深层次体现了电视节目的社会功能，求职过程富有悬念与挑战。

江苏卫视根据受众的心理需求和市场发展需要，先后举办了这两档节目，以娱乐大众，指点迷津为目的，取得了良好的成效。
由于之前《非诚勿扰》这一节目模式的空前成功，致使《职来职往》沿袭了他的舞台设计、环节设置和节目包装。
虽然，乍看上去，《职来职往》与《非诚勿扰》栏目有很多相似之处。
但对于求职者来说，这是一种全新的尝试，与相亲类节目不同的是《职来职往》将重点放在“立业”，以提供就业服务为主[11]。
节目并不一味追求娱乐性，作为具有舆论引导作用的电视媒体，更注重社会责任感。
通过舞台上的求职过程以及求职者与面试官的言论来呈现多元化社会现状，反应社会现实。
少了一些华而不实，多了一些脚踏实地。
