中国2008年有近30万的婴儿因食用三聚氰胺污染的婴儿配方奶粉而发生尿道疾病，其中六名婴儿死亡。
中国某些品牌的婴儿配方奶粉中三聚氰胺含量高被认为是直接导致小儿肾脏疾病爆发的主因，而且六名婴儿死亡病例中至少有三例与这些品牌的婴儿配方奶粉有关。
2008年9月以来，没有出现新的因三聚氰胺污染的奶类制品引起儿童死亡的报告。
三聚氰胺引起结晶尿并因而导致尿道上皮细胞炎症，肾结石，和急性肾功能衰竭。
事实速览∙食用在美国亚洲市场可以买到的中国生产的婴儿配方奶粉可能对婴儿健康造成危害。
∙美国生产的婴儿配方奶粉目前被认为是可以安全食用的。
∙最近刚刚从中国移民美国的婴儿，如果出现可疑的三聚氰胺引发的肾毒性临床症状，应尽快找小儿肾科专家咨询诊治。
∙避免食用来自中国的奶制品。
∙美国儿科肾脏专家协会的一个专家组对那些曾经生活在中国奶粉事件发生的区域但没有出现任何症状的婴儿，不建议做任何临床检验。
∙需要环境卫生咨询者，请联系儿童环境卫生专科门诊，电话 888-347-2632 或浏览儿童环境卫生专科门诊的网站，什么样的食品可能有三聚氰胺的污染？在中国，于2008年8月6日之前，三聚氰胺被非法添加到牛奶中，以此欺诈手段虚报蛋白质含量。
三聚氰胺污染的牛奶被用来制造婴儿配方奶和作为原料的各种奶制品和其他食品。
发现有三聚氰胺污染的中国制造的食品包括：∙婴儿配方奶（2008年8月6日以前）∙以牛奶为原料的食品∙鸡蛋∙宠物食品三聚氰胺在多种人和动物食品中被检测出来这一事实表明，三聚氰胺污染的中国食品可能仍然存在。
最近测试的美国生产的婴儿配方奶仅含有微量的三聚氰胺。
此微量浓度与导致婴儿患病的中国生产的婴儿配方奶中的三聚氰胺浓度相比，低了近10，000倍，而且，比美国食品药物管理局（FDA）规定的三聚氰胺在婴儿配方奶中可以接受的浓度还要低10倍。
什么是三聚氰胺？三聚氰胺是一种合成的化合物，用于塑料餐具，阻燃剂，纸张，纸板和工业涂料。
三聚氰胺是农药（ cryomazine ）的代谢产物以及食品设备清洁剂（ trichloromelamine ）的分解产物。

伊利替康 结构式 -回复
伊利替康结构式-回复伊利替康（Elidel）是一种局部用药治疗湿疹（atopic dermatitis）的药物。
它的主要成分是酯类化合物pimecrolimus。
伊利替康是一种非激素药物，被广泛使用于针对湿疹患者的长期治疗中，有效减轻患者的症状，并且具有较少的副作用。
本文将详细解析伊利替康的结构式，为读者提供更深入的了解。
首先我们来看一下伊利替康的结构式：酯类化合物pimecrolimus的化学名为(1S, 9S, 12S, 13E, 21R, 23R)-9, 21-dihydroxy-12-isopropyl-12-(2-methyl-1-oxobutoxy)-2,5,11,13,1 9-pentamethyl-8,21-dioxo-1H,20H-[1,4]oxazino[3,4]quinolizino[2,1 -a]isoquinoline-13-yl-2-methylpropanoate。
分析伊利替康的结构式，我们可以看到它由几个部分组成。
首先是氧杂吡咯（oxazino）的环结构，它是伊利替康的骨架。
吡咯环上连接着一个氮杂喹啉环（quinolizino）和一个异戊酸酯侧链。
在氮杂喹啉环上有一个吡美沙酮（pimecrolimus）基团。
伊利替康的结构中还有一些关键的官能团。
首先是两个羟基基团（hydroxyl group），它们分别连接在吡美沙酮基团的2号和21号碳原子上。
这些羟基基团在药效中扮演着重要的角色。
接下来是一个异丙基基团（isopropyl group），连接在吡美沙酮基团的12号碳原子上。
最后是一个异丁基基团（2-methyl-1-oxobutoxy），连接在吡美沙酮基团的12号羟基上。
伊利替康属于一类被称为calcineurin抑制剂（calcineurin inhibitors）的药物。
它通过抑制T细胞的活化和炎性细胞因子的释放，从而减轻过敏反应引起的炎症和瘙痒症状。
与传统的皮质类固醇类药物（如氢化可的松）相比，伊利替康作用于皮肤外层而不影响全身免疫系统，因此具有较少的副作用，尤其是在儿童和长期使用患者中。
Perkadox 16产品数据表说明书
Product Data SheetPerkadox 16Di(4-tert-butylcyclohexyl) peroxydicarbonatePerkadox® 16 is applied as an initiator for the suspension and mass polymerization of vinyl chloride in the temperature range between 40°C and 65°C.

The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.SADT40°CEmergency temperature (Tₑ)35°CControl temperature (Tc)30°CMethod The Heat Accumulation Storage Test is a recognized test method for thedetermination of the SADT of organic peroxides (see Recommendations on theTransport of Dangerous Goods, Manual of Tests and Criteria – United Nations,New York and Geneva).StorageDue to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, Nouryon recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.Ts max.20°C (please see note below)Note When stored under the recommended storage conditions, Perkadox® 16 willremain within the Nouryon specifications for a period of at least 3 months afterdelivery. The Ts max of 20°C is not to be interpretated as ambient or roomtemperature as this differs per region and season. Perkadox® 16 has a high qualitycomposition and to hold that it should be stored at below 20°C. At temperaturesabove 20°C the decomposition of Perkadox® 16 progresses fast which leads tosignificant loss of quality. If you have questions about this, please contact yourlocal Nouryon account manager for advice.Packaging and transportIn North America Perkadox® 16 is packed in non-returnable cartons containing 25 polyethylene bags of 1 lb net weightor 5 polyethylene bags of 5 lb net weight.

电子实验记录本的演变
电子实验记录本的演变实验记录本的主要作用一是能对实验记录以便将来能重复，二是避免对失败的实验进行不必要的重复，并在当前的基础上进行总结以推进研究的进展。
传统的实验记录都是纸质的，通过笔写记录，这种方式便于携带，易于使用。
如今，计算机在现代药物研发进程中的应用已经相当普及，许多需要记录的最原始数据都来源于电子计算机，而将这些数据手动得誊抄到纸质的记录本上很容易出错，特殊情况下，如许多分析数据（光谱，色谱，图像等）的誊抄是不可能实现的，只能打印出来进行粘贴。
到目前为止，纸质版本的实验记录本是当前信息化研发过程中唯一没有实现电子化的一环。
特别是当前面临高通量筛选和组合化学合成产生大量数据，笔写的工作负担非常繁重。
上个世纪90年代，许多公司开始意识到纸板本记录本上的数据价值非常重要，但同样也很容易丢失，如果要求研究人员在用笔记下数据后，又要再重新录入到数据库中并不现实，因此全面的电子化就解决方案应运而生，到90年代末期，大量的电子实验记录本定制化软件开发的项目应运而生，但研发业务的市场需求上认为定制化的ELN并没有好的竞争优势，产品化的ELN才是最佳选择。
对ELN的兴趣在2004年之前一直受抑制，2004年以前，国际质量和生产率中心（IQPC）在伦敦举办关于电子实验记录本的会议，当时参会人员大约只有30-40人，而到了2004年的九月，参与该会议的人数超过了120名，从此ELN成为一个非常热门的话题。
2004年的八月，一本名为“Electronic Laboratory Notebooks,a Foundation for Knowledge Management"的书由Atrium Research & Conculting的Michael Elliott出版发行，书中讨论了25种ELN的产品功能及价值。
时隔一年之后，该书的第二版问世。
之后许多ELN 的开发商兼并，组合，到目前为止市面上总共仍有29种ELN的产品（2005）。

In recent years, what have federal managers of Head Start been telling programs to do?Head Start TestingThis is Steve Ember with the VOA Special English Education Report.Four-year-old children in Head Start programs throughout the United States are taking a test. This test is meant to show if Head Start is succeeding in its goal. The goal is to make sure children from poor families are as prepared to begin school as other children. The four-year-olds are being tested for their ability to recognize simple words and letters in the alphabet. They are also being tested for their skills with numbers. Federal education officials say the test will help the Head Start program improve. The officials will compare the performance of the children against national averages in early arithmetic, reading and writing.Head Start began almost forty years ago. The children are between the ages ofthree and five. They receive free preparation for their first year in school. Some spend half a day in Head Start, others a full day. Still others take part in a program of home visits. Local non-profit organizations operate the programs. The government spends more than six-and-a-half thousand-million dollars a year to pay for Head Start.Federal officials say close to a million children throughout the country take part in the programs. Wade Horn leads the Head Start program for the government. Mr Horn says the test is designed to learn which kinds of programs help children the most. The United States Department of Health and Human Services released a report on Head Start in June. The agency compared Head Start children with children from average, middle-income families. It said the Head Start children are not as ready for school as the others. But some educators criticize the idea that one year in Head Start could raise poor children to average levels. Some also criticize parts of the test. For example, critics noted that the children are asked to point to a picture of a“swamp〞. They say a lot of children, especially from cities, might not know that a swamp is a wetland area with grass.Still, even some educators who oppose the test agree with federal officials that Head Start needs to do better to prepare children for school. Currently, local programs decide what they want to teach. Many have placed major importance on health, nutrition and social development. In recent years, federal managers of Head Start have been telling programs to place more importance on basic skills needed for school.This VOA Special English Education Report was written by Jerilyn Watson.

Standard Test Method forElectrostatic Decay of Nonwoven FabricsA number in Parentheses indicates the year of last revision.1. Scope1.1 This method determines the electrostatic properties of a material in film or sheet form by measuring the time required to dissipate a charge from the surface of the material.2. Referenced Documents2.1 ASTM Standards:D 123 Terminology Relating to Textiles 1D 1776 Practice for Conditioning Textiles forTesting 12.1 Other Standards:NFPA-99-92 Sec. 12-4.1.3.8(f) (3) 2Federal Test Method STD No. 101C, Method4046, Electrostatic Properties of Materials 33Terminology 3.1 Definitions :3.1.1 electrostatic decay , n – the ability of amaterial when grounded to dissipate a charge which has been induced on the surface of the material.3.1.2 decay time , n – the time in seconds for the induced charge to dissipate to 10% of its original level.4. Summary of the Method4.1 A flat sheet material is tested to determine its ability to dissipate an electrostatic charge by mounting samples of the material, subsequently charging the material to 5000V and then timing the charge dissipation.5. Significance and Use5.1 F abrics, films, nonwovens, or other materials which may be used in situations where electrostatic charge is objectionable may be tested using this method. These situations may be safety related such as use around flammable materials or practical such as handling the fabric or film on automated equipment.6. Apparatus6.1 Static Decay Meter (1) – The static decaymeter shall be capable of imparting a high voltage charge of at least 5000 volts positive and negative, and have a voltmeter and time capable of measuring the charge and timing its decay to a present limit. The meter should be equipped with a set of electrodes capable of supporting samples 89 x 140 mm (3.5 x 5.5in.) and making good electrical contact.6.2 Gloves – latex or cotton knit gloves which will prevent contamination of fabric surfaces.7. Sampling, Test Specimens and Test Units7.1 Take the bulk and laboratory samplesaccording to any applicable material specifications, or in their absence, take the laboratory sample in such a manner that it is representative of the lot to be tested.7.2 Take no specimen nearer the edge than 1/10 the width of the fabric.7.3 Five specimens should be taken in each direction per sample.7.4 If it is determined that a significant difference in performance exists between face and back then a double set of specimens should be run to evaluate performance of each surface.8. Preparation of Apparatus8.1 The test unit should be installed in aconditioned environment identical to the environment used to condition the specimens.8.2 The apparatus should be turned on and“warmed-up” for at least 30 minutes prior to calibration or testing.8.3 Calibrate the instrument using manufacturers instructions for the unit. This calibration should be done daily or alternately, prior to each round of testing.Calibration results should be recorded as part of a total quality system.8.4 Be sure the instrument is clean, and that the cut-off switch for the timer is set properly.8.5 Be sure the instrument is clean, and that the cutoff switch for the timer is set properly.9. Conditioning9.1 Samples should be conditioned at 50% R.H.and 23 ° + 1°C for 24 hours prior to testing. Testing should be carried out at these conditions. Samples should be exposed to these conditions following guidelines in ASTM D 1776.9.2 Other conditions may be required by product specifications and or standards. If test conditions are different from those mentioned above the results are not in compliance with NFPA 99. These conditions should be reported along with the test results.9.3 \\\\\\\INDA, Association of the Nonwoven Fabrics Industry1300 Crescent Green, Suite 135Cary, NC 27512Copyright 2001, INDA1 Annual Book of ASTM Standards, Vol. 07.01.2National Fire Protection Association, 1 Batterymarch ParkP.O.

A TENA-enabled Video Distribution System (VDS) was used to provide a dis-tributed visualization capability to the Information Operation (IO) Range during the Joint National Training Capability (JNTC) Austere Challenge 2006 (AC06) exercise. Development of the IO Range VDS was accomplished through col-laboration between the IO Range and the Joint Mission Environment Test Ca-pability (JMETC) programs, resulting in a first time achievement of bringing real-time visualization of live fire IO events to the combatant commanders (COCOM), both CONUS and OCONUS, via the SIPRNet. IO RANGE Video Distribution System The IO RANGE Video Distribution System (VDS) concept was based on an early TENA Data Stream Framework prototyped in FY2004 and leveraged a non-TENA Video Capture & Distribution System being developed for the Red-stone Technical Test Center (RTTC). The JMETC development team was able to quickly adapt their solution (see figure 1) using TENA and requiring less than four weeks to develop, implement, test, and integrate for the exercise. IO RANGE Requirements for the VDS included: 1. Solution for injecting video streams into SIPRNet, 2. Ability to distribute to multiple end user systems at a minimum 1 frame/sec, with seconds of latency, resolution to support projection and over limited bandwidth connections; 3. Ability to record video for playback; and 4. Ability to playback video using a COTS Viewer (Microsoft MediaPlayer). For IO RANGE/AC06, the real-time video stream was provided from a single source bridged into the network. The TENA Video Distribution Server pub-lished availability of data streams via a VideoStream object and published
availability of recorded streams for playback via a VideoStreamServer object.

TENA Video Distribution clients would discover the availability of VideoStream objects and request data stream files to be streamed for replay. TENA-enabled clients could display and request available live and replay video sources. Non-TENA clients display video sources requested by TENA-enabled clients or server using URL information passed via secure voice/email.
Summary
The IO RANGE VDS supported over thirty clients during the AC06 exercise without a single failure of the TENA Video Distribution Server. The auto-code generated distribution provided by TENA enabled the JMETC developers to greatly reduce the time needed to integrate and test their software. The IO RANGE brought transformational IO capabilities to the IO community during AC06, providing the warfighter a standing, robust environment for experimentation, testing training, exercises, and operational rehearsal. JMETC brought a technology solution using the TENA common operating environment and an experi-enced, quick response development and integration support team.
The RTTC Video Capture & Distribution System is being developed by the Trideum Corporation of Hunts-ville, Alabama.
