Throughout the course of history, people have travelled for purposes of trade, religious conviction, economic gain, war, migration and other equally compelling motivations. In the Roman era, wealthy aristocrats and high government officials also travelled for pleasure. Seaside resorts located at Pompeii and Herculaneum afforded citizens the opportunity to escape to their vacation villas in order to avoid the summer heat of Rome. Travel, except during the Dark Ages, has continued to grow and, throughout recorded history, has played a vital role in the development of civilisations and their economies.B Tourism in the mass form as we know it today is a distinctly twentieth-century phenomenon. Historians suggest that the advent of mass tourism began in England during the industrial revolution with the rise of the middle class and the availability of relatively inexpensive transportation. The creation of the commercial airline industry following the Second World War and the subsequent development of the jet aircraft in the 1950s signalled the rapid growth and expansion of international travel. This growth led to the development of a major new industry: tourism. In turn, international tourism became the concern of a number of world governments since it not only provided new employment opportunities but also produced a means of earning foreign exchange.C Tourism today has grown significantly in both economic and social importance. In most industrialised countries over thepast few years the fastest growth has been seen in the area of services. One of the largest segments of the service industry, although largely unrecognised as an entity in some of these countries, is travel and tourism. According to the World Travel and Tourism Council (1992), ‘Travel and tourism is the largest industry in the world on virtually any economic measure including value-added capital investment, employment and tax contributions’. In 1992, the industry’s gross output was estimated to be $3.5 trillion, over 12 per cent of all consumer spending. The travel and tourism industry is the world’s largest employer with almost 130 million jobs, or almost 7 per cent of all employees. This industry is the world’s leading industrial contributor, producing over 6 per cent of the world’s national product and accounting for capital investment in excess of $422 billion in direct, indirect and personal taxes each year. Thus, tourism has a profound impact both on the world economy and, because of the educative effect of travel and the effects on employment, on society itself.D However, the major problems of the travel and tourism industry that have hidden, or obscured, its economic impact are the diversity and fragmentation of the industry itself. The travel industry includes: hotels, motels and other types of accommodation; restaurants and other food services; transportation services and facilities; amusements, attractions and other leisure facilities; gift shops and a large number of other enterprises. Since many of these businesses also serve local residents, the impact of spending by visitors can easily be overlooked or underestimated. In addition, Meis (1992) points out that the tourism industry involves concepts that have remained amorphous to both analysts and decision makers.Moreover, in all nations this problem has made it difficult for the industry to develop any type of reliable or credible tourism information base in order to estimate the contribution it makes to regional, national and global economies. However, the nature of this very diversity makes travel and tourism ideal vehicles for economic development in a wide variety of countries, regions or communities.E Once the exclusive province of the wealthy, travel and tourism have become an institutionalised way of life for most of the population. In fact, McIntosh and Goeldner (1990) suggest that tourism has become the largest commodity in international trade for many nations and, for a significant number of other countries, it ranks second or third. For example, tourism is the major source of income in Bermuda, Greece, Italy, Spain, Switzerland and most Caribbean countries. In addition, Hawkins and Ritchie, quoting from data published by the American Express Company, suggest that the travel and tourism industry is the number one ranked employer in the Bahamas, Brazil, Canada, France, (the former) West Germany, Hong Kong, Italy, Jamaica, Japan, Singapore, the United Kingdom and the United States. However, because of problems of definition, which directly affect statistical measurement, it is not possible with any degree of certainty to provide precise, valid or reliable data about the extent of world-wide tourism participation or its economic impact. In many cases, similar difficulties arise when attempts are made to measure domestic tourism.Questions 5-10Do the following statements agree with the information given in Reading Passage 1?In boxes 5-10 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this5 The largest employment figures in the world are found in the travel and tourism industry.6 Tourism contributes over six per cent of the Australian gross national product.7 Tourism has a social impact because it promotes recreation.8 Two main features of the travel and tourism industry make its economic significance difficult to ascertain.9 Visitor spending is always greater than the spending of residents in tourist areas.10 It is easy to show statistically how tourism affects individual economies.Questions 11-13Complete the sentences below.Choose NO MORE THAN THREE WORDS from the passage for each answer.Write your answers in boxes 11-13 on your answer sheet.11 In Greece, tourism is the most important .12 The travel and tourism industry in Jamaica is the major .13 The problems associated with measuring international tourism are often reflected in the measurement of .READING PASSAGE 2You should spend about 20 minutes on Questions 14-26, which are based on Reading Passage 2 below.Autumn leavesCanadian writer Jay Ingram investigates the mystery of why leaves turn red in the fallA One of the most captivating natural events of the year inmany areas throughout North America is the turning of the leaves in the fall. The colours are magnificent, but the question of exactly why some trees turn yellow or orange, and others red or purple, is something which has long puzzled scientists.B Summer leaves are green because they are full of chlorophyll, the molecule that captures sunlight and converts that energy into new building materials for the tree. As fall approaches in the northern hemisphere, the amount of solar energy available declines considerably. For many trees —evergreen conifers being an exception — the best strategy is to abandon photosynthesis_until the spring. So rather than maintaining the now redundant leaves throughout the winter, the tree saves its precious resources and discards them. But before letting its leaves go, the tree dismantles their chlorophyll molecules and ships their valuable nitrogen back into the twigs. As chlorophyll is depleted, other colours that have been dominated by it throughout the summer begin to be revealed. This unmasking explains the autumn colours of yellow and orange, but not the brilliant reds and purples of trees such as the maple or sumac.C The source of the red is widely known: it is created by anthocyanins, water-soluble plant pigments reflecting the red to blue range of the visible spectrum. They belong to a class of sugar-based chemical compounds also known as flavonoids. What’s puzzling is tha t anthocyanins are actually newly minted, made in the leaves at the same time as the tree is preparing to drop them. But it is hard to make sense of the manufacture of anthocyanins — why should a tree bother making new chemicals in its leaves when it’s alr eady scrambling to withdraw and preserve the ones already there?D Some theories about anthocyanins have argued that they might act as a chemical defence against attacks by insects or fungi, or that they might attract fruit-eating birds or increase a leaf’s tolerance to freezing. However there are problems with each of these theories, including the fact that leaves are red for such a relatively short period that the expense of energy needed to manufacture the anthocyanins would outweigh any anti-fungal or anti-herbivore activity achieved._photosynthesis: the production of new material from sunlight, water and carbon dioxideE It has also been proposed that trees may produce vivid red colours to convince herbivorous insects that they are healthy and robust and would be easily able to mount chemical defences against infestation. If insects paid attention to such advertisements, they might be prompted to lay their eggs on a duller, and presumably less resistant host. The flaw in this theory lies in the lack of proof to support it. No one has as yet ascertained whether more robust trees sport the brightest leaves, or whether insects make choices according to colour intensity.F Perhaps the most plausible suggestion as to why leaves would go to the trouble of maki ng anthocyanins when they’re busy packing up for the winter is the theory known as the ‘light screen’ hypothesis. It sounds paradoxical, because the idea behind this hypothesis is that the red pigment is made in autumn leaves to protect chlorophyll, the light-absorbing chemical, from too much light. Why does chlorophyll need protection when it is the natural world’s supreme light absorber? Why protect chlorophyll at a time when the tree is breaking it down to salvage as much of it as possible?G Chlorophyll, although exquisitely evolved to capture theenergy of sunlight, can sometimes be overwhelmed by it, especially in situations of drought, low temperatures, or nutrient deficiency. Moreover, the problem of oversensitivity to light is even more acute in the fall, when the leaf is busy preparing for winter by dismantling its internal machinery. The energy absorbed by the chlorophyll molecules of the unstable autumn leaf is not immediately channelled into useful products and processes, as it would be in an intact summer leaf. The weakened fall leaf then becomes vulnerable to the highly destructive effects of the oxygen created by the excited chlorophyll molecules.H Even if you had never suspected that this is what was going on when leaves turn red, there are clues out there. One is straightforward: on many trees, the leaves that are the reddest are those on the side of the tree which gets most sun. Not only that, but the red is brighter on the upper side of the leaf. It has also been recognised for decades that the best conditions for intense red colours are dry, sunny days and cool nights, conditions that nicely match those that make leaves susceptible to excess light. And finally, trees such as maples usually get much redder the more north you travel in the northern hemisphere. It’s colder there, they’re more stressed, their chlorophyll is more sensitive and it needs more sunblock.I What is still not fully understood, however, is why some trees resort to producing red pigments while others don’t bother, and simply reveal their orange or yellow hues. Do these trees have other means at their disposal to prevent overexposure to light in autumn? Their story, though not as spectacular to the eye, will surely turn out to be as subtle and as complex.Questions 14-18Reading Passage 2 has nine paragraphs, A-I.Which paragraph contains the following information?Write the correct letter, A-I, in boxes 14-18 on your answer sheet.NB You may use any letter more than once.14 a description of the substance responsible for the red colouration of leaves15 the reason why trees drop their leaves in autumn16 some evidence to confirm a theory about the purpose of the red leaves17 an explanation of the function of chlorophyll18 a suggestion that the red colouration in leaves could serve as a warning signalQuestions 19-22Complete the notes below.Choose ONE WORD ONLY from the passage for each answer.Write your answers in boxes 19-22 on your answer sheet.Why believe the ‘light screen’ hypothesis?The most vividly coloured red leaves are found on the side of the tree facing the 19 .The 20 surfaces of leaves contain the most red pigment.Red leaves are most abundant when daytime weather conditions are 21 and sunny.The intensity of the red colour of leaves increases as you go further 22 .Questions 23-25Do the following statements agree with the information given in Reading Passage 2?In boxes 23-25 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this23 It is likely that the red pigments help to protect the leaf from freezing temperatures.24 The ‘light screen’ hypothesis would initially seem to contradict what is known about chlorophyll.25 Leaves which turn colours other than red are more likely to be damaged by sunlight.Question 26Choose the correct letter A, B, C or D.Write the correct letter in box 26 on your answer sheet.For which of the following questions does the writer offer an explanation?A why conifers remain green in winterB how leaves turn orange and yellow in autumnC how herbivorous insects choose which trees to lay their eggs inD why anthocyanins are restricted to certain treesREADING PASSAGE 3You should spend about 20 minutes on Questions 27-40, which are based on Reading Passage 3 below.Beyond the blue horizonAncient voyagers who settled the far-flung islands of the Pacific OceanAn important archaeological discovery on the island of Efate in the Pacific archipelago of Vanuatu has revealed traces of an ancient seafaring people, the distant ancestors of today’s Polynesians. The site came to light only by chance. An agricultural worker, digging in the grounds of a derelict plantation, scraped open a grave — the first of dozens in a burial ground some 3,000 years old. It is the oldest cemetery ever found in the Pacificislands, and it harbors the remains of an ancient people archaeologists call the Lapita.They were daring blue-water adventurers who used basic canoes to rove across the ocean. But they were not just explorers. They were also pioneers who carried with them everything they would need to build new lives — their livestock, taro seedlings and stone tools. Within the span of several centuries, the Lapita stretched the boundaries of their world from the jungle-clad volcanoes of Papua New Guinea to the loneliest coral outliers of Tonga.The Lapita left precious few clues about themselves, but Efate expands the volume of data available to researchers dramatically. The remains of 62 individuals have been uncovered so far, and archaeologists were also thrilled to find six complete Lapita pots. Other items included a Lapita burial urn with modeled birds arranged on the rim as though peering down at the human remains sealed inside. ‘It’s an important discovery,’ says Matthew Spriggs, professor of archaeology at the Australian National University and head of the international team digging up the site, ‘for it conclusively identifies the remains as Lapita.’DNA teased from these human remains may help answer one of the most puzzling questions in Pacific anthropology: did all Pacific islanders spring from one source or many? Was there only one outward migration from a single point in Asia, or several from different points? ‘This represents the best opportunity we’ve had yet,’ says Spriggs, ‘to find out who the Lapita actually were, where they came from, and who their closest descendants are today.’There is one stubborn question for which archaeology has yet to provide any answers: how did the Lapita accomplish theancient equivalent of a moon landing, many times over? No-one has found one of their canoes or any rigging, which could reveal how the canoes were sailed. Nor do the oral histories and traditions of later Polynesians offer any insights, for they turn into myths long before they reach as far back in time as the Lapita.‘All we can say for certain is that the Lapita had canoes that were capable of ocean voyages, and they had the ability to sail them,’ says Geoff Irwin, a professor of archaeology at the University of Auckland. Those sailing skills, he says, were developed and passed down over thousands of years by earlier mariners who worked their way through the archipelagoes of the western Pacific, making short crossings to nearby islands. The real adventure didn’t begin, however, until their Lapita descendants sailed out of sight of land, with empty horizons on every side. This must have been as difficult for them as landing on the moon is for us today. Certainly it distinguished them from their ancestors, but what gave them the courage to launch out on such risky voyages?The Lapita’s thrust into the Pacific was eastward, against the prevailing trade winds, Irwin notes. Those nagging headwinds, he argues, may have been the key to their success. ‘They could sail out for days into the unknown and assess the area, secure in the knowledge that if they didn’t find anything, they could turn about and catch a swift ride back on the trade winds. This is what would have made the whole thing work.’ Once out there, skilled seafarers would have detected abundant leads to follow to land: seabirds, coconuts and twigs carried out to sea by the tides, and the afternoon pile-up of clouds on the horizon which often indicates an island in the distance.For returning explorers, successful or not, the geography oftheir own archipelagoes would have provided a safety net. Without this to go by, overshooting their home ports, getting lost and sailing off into eternity would have been all too easy. Vanuatu, for example, stretches more than 500 miles in a northwest-southeast trend, its scores of intervisible islands forming a backstop for mariners riding the trade winds home.All this presupposes one essential detail, says Atholl Anderson, professor of prehistory at the Australian National University: the Lapita had mastered the advanced art of sailing against the wind. ‘And there’s no proof they could do any such thing,’ Anderson says. ‘There has been this assumption they did, and people have built canoes to re-create those early voyages based on that assumption. But nobody has any idea what their canoes looked like or how they were rigged.’Rather than give all the credit to human skill, Anderson invokes the winds of chance. El Nino, the same climate disruption that affects the Pacific today, may have helped scatter the Lapita, Anderson suggests. He points out that climate data obtained from slow-growing corals around the Pacific indicate a series of unusually frequent El Ninos around the time of the Lapita expansion. By reversing the regular east-to-west flow of the trade winds for weeks at a time, these ‘super El Ninos’ might have taken the Lapita on long unplanned voyages.However they did it, the Lapita spread themselves a third of the way across the Pacific, then called it quits for reasons known only to them. Ahead lay the vast emptiness of the central Pacific and perhaps they were too thinly stretched to venture farther. They probably never numbered more than a few thousand in total, and in their rapid migration eastward they encountered hundreds of islands — more than 300 in Fiji alone.Questions 27-31Complete the summary using the list of words and phrases, A-J, below.Write the correct letter, A-J, in boxes 27-31 on your sheet.The Efate burial siteA 3,000-year-old burial ground of a seafaring people called the Lapita has been found on an abandoned 27 on the Pacific island of Efate.

11.0It is not intended that the determination of total protein and human coagulation factor VIII shown below be carried out on each unit of plasma.They are rather given as guidelines for good manufacturing practice,the test for human coagulation factor VIII being relevant for plasma intended for use in the preparation of concentrates of labile proteins.The total proteincontentof a unitof plasma depends on theserum protein content of the donor and the degree of dilution inherent in the donation procedure.When plasma is obtained from a suitable donorandusing the intendedproportionofanticoagulant solution,a total protein content complying with the limit of 50 g/L is obtained.If a volume of blood or plasma smaller than intended is collected into the anticoagulantsolution,the resulting plasma is not necessarily unsuitable forpooling for fractionation.The aim of good manufacturing practice must be to achieve the prescribed limit for all normal donations.Preservation of human coagulation factor VIII in the donation depends on the collection procedure and the subsequent handling of the bloodandplasma.Withgoodpractice,0.7 IU/mL can usually be achieved,but units of plasma with alower activity may still be suitable for use in the production of coagulation factor concentrates.The aim of allstepstakenduring production of plasma is to obtain plasma of the intended quality and to conserve labile proteins as much as possible.Total protein .Carry out the test using a pool of not fewer than 10 units.Dilute anappropriate volume of the preparationwith a 9 g/L solution of sodium chloride R to obtain a solution containing about 15 mg of protein in 2 mL.To 2.0 mL of this solution in a round-bottomedcentrifugetube,add 2 mLof a 75 g/L solution of sodium molybdate R and 2 mL of a mixture of 1 volume of nitrogen-free sulfuric acid R and 30 volumes of water R .Shake,centrifuge for 5 min,decantthe supernatant and allow the inverted tube to drain on filter paper.Determine the nitrogen in the residue by the method of sulfuric acid digestion (2.5.9)and calculate the protein content by multiplying the quantity of nitrogen by

Frozen plasma is stored and transported in conditions designed to maintain the temperature at or below − 20 °C;for accidental reasons,the storage temperature may riseabove − 20 °C on one or more occasions during storage and transport but the plasma is nevertheless considered suitable for fractionation if all the following conditions are fulfilled:–the total period of time during which the temperature exceeds − 20 °C does not exceed 72 h;–the temperature does not exceed − 15 °C on more than 1 occasion;–the temperature at no time exceeds − 5 °C.POOLED PLASMA During the manufacture of plasma products,the first homogeneous pool of plasma (for example,after removal of cryoprecipitate)is tested for HBsAgand forHIV antibodies using test methods of suitable sensitivity and specificity;the pool must give negative results in these tests.The plasma pool is also tested for hepatitis C virus RNA using a validated nucleicacid amplificationtechnique (2.6.21).Apositive control

珊瑚白化英语作文
珊瑚白化英语作文Here is an English essay on the topic of coral bleaching, with the content exceeding 1000 words as requested. The title is not included in the word count.Coral Bleaching: A Global Phenomenon with Dire ConsequencesCoral reefs are renowned as the underwater rainforests of our planet, teeming with an incredible diversity of marine life and serving as vital ecosystems for countless species. However, in recent decades, these vibrant underwater havens have been facing a grave threat – coral bleaching. This phenomenon, driven by a complex interplay of environmental factors, has been causing widespread devastation to coral communities around the world, with far-reaching implications for the delicate balance of our marine ecosystems.At the heart of the coral bleaching crisis lies the issue of rising ocean temperatures. As a result of climate change and the ongoing global warming, the world's oceans have been steadily warming, with the average sea surface temperature increasing by approximately 0.13°C per decade over the past century. This seemingly small change in temperature has had a profound impact on the delicate balance ofcoral reef ecosystems.Corals, being sensitive organisms, rely on a symbiotic relationship with microscopic algae known as zooxanthellae. These algae reside within the coral's tissue and provide the corals with essential nutrients and energy through photosynthesis. However, when the ocean temperatures rise beyond the corals' optimal range, this delicate relationship is disrupted. The corals, under stress, expel the zooxanthellae, causing them to lose their vibrant colors and appear "bleached."Without the zooxanthellae, the corals lose their primary source of energy and nutrients, leaving them vulnerable to disease, starvation, and ultimately, death. The loss of these foundational species has a cascading effect on the entire reef ecosystem, as the intricate web of life that depends on the corals is severely disrupted.The impacts of coral bleaching extend far beyond the immediate loss of the corals themselves. These vibrant underwater ecosystems serve as critical habitats for a vast array of marine life, ranging from colorful fish and invertebrates to endangered species such as sea turtles and dugongs. When corals die, the entire ecosystem that relies on them is thrown into disarray, with many species losing their homes, food sources, and breeding grounds.Moreover, coral reefs play a vital role in protecting coastal communities from the destructive forces of waves and storms. Their intricate structures act as natural barriers, absorbing the energy of waves and shielding shorelines from erosion and flooding. As coral reefs decline, these crucial ecosystem services are compromised, leaving coastal communities increasingly vulnerable to the impacts of climate change and extreme weather events.The economic consequences of coral bleaching are also significant. Coral reefs are a major draw for ecotourism, with millions of people visiting these underwater wonders each year. The loss of these vibrant ecosystems can have a devastating impact on local economies that rely heavily on the revenue generated by diving, snorkeling, and other reef-based activities. Additionally, the decline of coral reefs can disrupt local fisheries, threatening the livelihoods of coastal communities that depend on the bounty of the sea.In response to the growing threat of coral bleaching, scientists and conservation organizations have been working tirelessly to understand the underlying causes and develop strategies to mitigate the damage. One of the key focus areas has been addressing the root cause of the problem – climate change. Reducing greenhouse gas emissions and transitioning to renewable energy sources are crucial steps in slowing the rate of ocean warming and giving corals a fighting chance to survive.In parallel, efforts are being made to develop more resilient coral strains that can better withstand the impacts of climate change. Through selective breeding and genetic engineering, researchers are exploring ways to create coral species that are more resistant to the stresses of rising temperatures and ocean acidification. Additionally, techniques such as coral transplantation and the establishment of marine protected areas are being employed to help preserve and restore damaged reef ecosystems.However, the challenges facing coral reefs are immense, and the solutions are not always straightforward. Coral bleaching is a global phenomenon, requiring coordinated international efforts to address the underlying drivers and implement effective conservation strategies. The success of these efforts will not only determine the fate of the world's coral reefs but also the well-being of the countless species and human communities that rely on them.In conclusion, the coral bleaching crisis is a stark reminder of the profound impact that human activities can have on the delicate balance of our planet's ecosystems. As we grapple with the realities of climate change and its far-reaching consequences, it is imperative that we take immediate and decisive action to protect the world's coral reefs. By working together to reduce our carbon footprint, support conservation efforts, and develop innovative solutions, wecan strive to preserve these underwater havens for generations to come, and ensure the continued health and resilience of our marine ecosystems.。
蝴蝶的保护色英语作文
蝴蝶的保护色英语作文Title: The Protective Coloration of Butterflies。
Butterflies are among the most enchanting creatures on our planet, captivating us with their vibrant colors and delicate wings. However, beneath their aesthetic appeallies a fascinating survival strategy: protective coloration. This phenomenon, also known as camouflage, plays a crucial role in the survival and evolution of butterflies.Protective coloration in butterflies serves primarilyas a defense mechanism against predators. By blending seamlessly into their surroundings, butterflies can avoid detection and reduce the risk of being eaten. This adaptation comes in various forms, each tailored to the specific habitats and lifestyles of different butterfly species.One common type of protective coloration is cryptic coloration, where butterflies' wing patterns resemble thetextures and colors of their natural environment. For instance, species living in forested areas may have wings adorned with patterns resembling tree bark or foliage. This allows them to effectively camouflage themselves against tree trunks or among leaves, making them virtuallyinvisible to predators such as birds and lizards.Another form of protective coloration is disruptive coloration, which involves patterns that break up the outline of the butterfly's body, making it difficult for predators to recognize them as prey. This strategy is particularly effective when butterflies are in motion, as the disruptive patterns create visual confusion, making it challenging for predators to accurately target them.Furthermore, some butterflies exhibit mimicry, where their coloration closely resembles that of other unpalatable or toxic species. This deceptive tactic deters predators who have learned to associate certain color patterns with a foul taste or even danger. By mimicking these warning signals, butterflies gain protection without having to invest in producing toxins themselves.The evolution of protective coloration in butterflies is a result of natural selection acting upon heritable variations in color patterns. Over time, individuals with better camouflage have higher chances of survival and reproduction, passing on their advantageous traits tofuture generations. This process continually refines and enhances the effectiveness of protective coloration in butterfly populations.However, the effectiveness of protective coloration is not solely determined by the appearance of butterflies. Environmental factors such as light conditions, background texture, and the presence of predators also influence how effective camouflage can be. Additionally, human activities such as habitat destruction and pollution can disrupt the natural environments where butterflies reside, further challenging their survival.Conservation efforts play a crucial role in safeguarding the habitats of butterflies and preserving their intricate adaptations, including protectivecoloration. By protecting natural ecosystems and minimizing human disturbances, we can ensure that butterflies continue to thrive and enchant future generations with their beauty and resilience.In conclusion, protective coloration is a remarkable adaptation that enables butterflies to evade predators and survive in diverse environments. Through cryptic coloration, disruptive patterns, and mimicry, butterflies have evolved sophisticated strategies to blend into their surroundings and avoid detection. Understanding and appreciating the significance of protective coloration not only enriches our knowledge of butterfly biology but also underscores the importance of conservation in preserving these delicate yet resilient creatures.。

自花授粉作物自交不退化,作文英文回答:Self-pollinating crops, also known as self-fertilizingor selfing crops, do not experience degradation through inbreeding. This means that they can reproduce successfully without the need for cross-pollination from another individual plant.One example of a self-pollinating crop is wheat. Wheat plants have both male and female reproductive structures, allowing them to self-fertilize. The pollen from the male organ, called the anther, can easily reach the female organ, called the stigma, within the same flower. This ensures successful fertilization and the production of viable seeds.Another example is tomatoes. Tomato plants have flowers that contain both male and female parts. When the pollen from the anther is released, it can easily come intocontact with the stigma within the same flower, leading toself-pollination. This is why tomato plants can producefruits even when grown in isolation.Self-pollinating crops have several advantages. Firstly, they do not rely on external pollinators such as bees or wind to transfer pollen, which can be a limiting factor in areas with low pollinator populations or adverse weather conditions. Secondly, self-pollination ensures genetic consistency and stability within a crop. This can be beneficial for farmers who want to maintain specific traits or characteristics in their crops, such as disease resistance or high yield.However, there are also disadvantages to self-pollination. One major drawback is the reduced genetic diversity within a population. When plants self-pollinate, they are essentially mating with themselves, leading to a decrease in genetic variation. This can make the crop more susceptible to diseases and pests, as well as reducing its ability to adapt to changing environmental conditions.中文回答:自花授粉作物,也被称为自育或自交作物,不会因近亲繁殖而退化。

《Notre Dame cathedral》is one known far and wide romantic faction strength which Victor Hugo writes . I take advantage of this summer vacation free time,read this great work.Notre Dame cathedral's story,actually was one at that time social epic poem,since brimmed with really. Friendly. Beautiful,also the flow selfish desire and is false. Regardless of is good beautiful Asmelada,or has the ugly semblance,Cacimodo with one pure mind,they represent the great amount the lower level populace which suppresses;Perhaps is sinister Coloud,he is appears by the theocracy face,all load bearing one kind of author's ponder.The author in this work,for with the clown,was beautifully friendly and wickedly does the best annotation,or take above three people as the example,the rebel Asmelada has the beautiful semblance and the chaste good mind,as well as pitiful destiny,but Cacimodo,he withstood destiny deceive nicely,the innermost feelings is his misery is graver,but Coloud maintained the benighted social rights and interests,he had brutally. Void mind and evil passion. Good person physique hateful,but the evil person actually says the appearance shore however,bright set off,social unfair manifest.But the article result also is when the opposition society until criticism:All beautiful is good all swallows by the might and theevil,the lower level people's weak strength in under the king power rule,in the benighted society,only can be reduced to ashes. Was palatial Notre Dame cathedral,how many world tragedy testimony once,in Hugo the novel,he as if had the life breath,he sheltered Asmelada,exposed Coloud the crime,regret the populace attack the magnificent feat which dark actually heroically devoted……Another the question which is worth pondering is:Who is the hero?Asmelada or Cacimodo?I think all is not,but is in the article by the Louis 11 rank smell of blood suppression rather for sacreficed the populace gate,Asmelada with Cacimodo is not in them the representative,Asmelada is loves with the beautiful symbol,Cacimodo not many represents is unfortunate and the pain. But they,all suffer a tragic middle ages ignorant evil forces devastate,one each one painful soul is bleeding,flows the tear. Merely is Notre Dame cathedral's above engraves " the destiny "?They are in middle ages France,despotism sacrificial victim.The entire story rich tragic color,the plot intense is moving,exciting. Author Hugo through " Notre Dame cathedral " this story,but also disclosed at that time the dark society's essence to the people.

Comparison of Single-Use Surgical Scissors with Reprocessed Single-Use Laparoscopic Surgical ScissorsA. SantosaAbstract: Quality and performance testing was performed on reprocessed single use Microline PENTAX (MPI) scissors to compare the single use MPI scissors direct from the company. The results illustrate the extensive damage that takes place in reuse, and sterilization and sharpening process of reprocessed scissors. Furthermore the study provides evidence that functionality of the scissors is compromised. The delicate manufacturing of theses specialized blades are designed, optimized and FDA cleared for single use. Reprocessing results in low blade performance and may introduce the risk of several clinical complications (e.g. infection, unintentional burns from compromised insulation, etc.).aIndependent business consultantIntroduction: MPI scissors are designed and allow smaller more precise and controlled cuts clinically tested for optimal performance and safety with smoother action potentially reducing the risk in single use applications. They are not designed of cutting unintended vessels or tissue. b. for the conditions encountered during reprocessing a. or repeated use. After learning of several complications and suboptimal performance surgeons experienced with reprocessed MPI scissors, we set out to conduct a study to measure the disparity between the reprocessed and original scissors.

The data suggests a deficient 3.

Damage to the blades: extensive damage was noticeable with the naked eye; the blades were a. to end, delivering the smooth continuous cut. b. physically dulled and damaged (Figure1).

The insulation tubing has been changed to an unknown material and is not positioned correctly over the shaft. Improper insulation can cause unintended burns during cauterization or sparking at the blade opening. Results of Scissor Efficacy Testing: Re-processed scissors fail quality control tests (Figure 4). Scissors fail the tip catch test, confirming that functionality is compromised during the sharpening, cleaning, and reuse process. Inadequate cutting by the scissor tip can lead to multiple tip or full scissor changes during surgeries, potentially driving up surgery cots.a. b.leaves the hospital. This can result in multiple hospitalizations and surgeries as well as long periods away from work, and this in turn can increase the risk of personal injury lawsuit Another risk of using reprocessed devices is unsuccessful decontamination and sterilization. Studies have shown that up to 40% of re-sterilized single use scissors remain un-sterilized after resterilization5. There is no way to know if the sterilization process has effetely decontaminated microbes and tissue that may reside between the blades and in small crevices. Every additional step (re-sterilization, tip changes, etc.) introduces an opportunity for error. Discussion of Efficacy Implications: Testing showed that re-processing single use MPI scissors compromised the integrity of the blade and results in a deficient cut. This is similar to the findings of Roth et al6 whose research found that 54% of reprocessed single use scissors failed functionality testing. The sharpest scissor blade delivers the finest and most controlled cut. A fine controlled cut results in improved healing and lowers the likelihood of complications. Better healing lowers the costs and time associated with recovery. Stringent manufacturing practices at MPI produces the best-in-class scissors under strict quality control and testing. This is done to assure the surgeon that they will get the same cut, the consistent cut, every time. Reliability and predictability of the MPI scissors give surgeons peace of mind, self confidence, and control. MPI scissors enable surgeons to work at the top of their game. The reprocessed scissors can not do this because they have not passed, and indeed they fail, MPI’s strict QA testing. Reprocessed scissors can give surgeons a handicap of a dull or imprecise scissor, making their job more difficult. Conclusions: Using single use scissors, as directed, for single use is a way of taking precautionary measures to ensure you have the highest quality products at all times, eliminating a variable that could cause complications during surgery. Hospitals may want to reconsider the reprocessing of certain medical devices that are designed for single use. Surgeons should ask if the scissors handed to them in surgery have been reprocessed for the benefit of their patients. Best practices; best surgery!Roth, K. “Specific hygiene issues related to reprocessing and reuse of single-use devices for laparoscopic surgery.” Sug Endosc 16: 1091-1097(2002). 6 Roth, K. “Specific hygiene issues related to reprocessing and reuse of single-use devices for laparoscopic surgery.” Sug Endosc 16: 1091-1097(2002).5Figure 4: a) Reprocessed MPI 3152 blade showing the tip catching on latex during the tip catch test. b)Unused MPI 3152 blade making a clean cut of the latex.Inadequate cutting may also result in lower satisfaction for the surgeon. If an original manufacture scissors does not feel right to the surgeon, it is possible that it is reprocessed. Discussion of Safety Implications: Re-sterilization greatly increases the risk of damaging the insulation by accelerating the breakdown of the insulating material; thereby increasing the risk of unsuspected thermal injuries2 such as: organ damage, vessel hemorrhage, perforation, peritonitis, death, and painful adhesions. Visual inspection of reprocessed scissors (the only current method of inspection by reprocessors) may not show small cracks in insulation from disinfection and sterilization3. These small cracks are extremely dangerous and are likely to produce a burn because the energy is concentrated on such a small area4. Many symptoms of thermal burns from insufficient insulation go unnoticed until the patient2/medical.asp?page=/ENGLISH/PUBS/FEATURES/ELS-104-WHT Page 5 of 16 (8/1/2007): 1)Wolfe BM, Gardiner BN, Leary BF, Frey CF.
