医学类英语文章

人食五谷杂粮，总会有生病的时候，这时医学就显得尤为重要。下面是我带来的，欢迎阅读! Joseph Heller’s Catch-22 is one of the most acclaimed novels of the twentieth century. It is a black edy about life in the military during World War II. It features bombardier John Yossarian, who is trying to survive the military’s inexhaustible supply of bureaucracy and who is frantically trying to do anything to avoid killing and being killed. Heller was able to use his own experiences in the Air Force during World War II to create this character and the novel. Even though Catch-22 eventually became known as a great novel, it was not originally considered one. When it was first published in 1961, the reviews were tepid and the sales were lackluster. It was not well received at this point at least in part because it presented such a cowardly protagonist at a time when World War II veterans were being lauded for their selfless courage. Within a few years of the release of the book, as an unpopular war in Southeast Asia was heating up, Heller’s Catch-22 found a new audience eager to enjoy the exploits of Heller’s war-averse protagonist. It was within the framework of this era that Catch-22 was newly discovered, newly examined, and newly credited as one of the century’s best novels. Let me talk a bit about the expression catch-22. Do you understand what a catch-22 is? This expression is so well known now that it has entered the American lexicon: well, a catch-22 is a situation that is unresolvable, one where there is no good choice, not best path to take. In Heller’s novel, the catch-22 is a very specific catch in a very specific situation. The situation in which the protagonist found himself was that he wanted to get out of bat by declaring himself insane. So you see that in this situation, there was a very specific catch. In American culture now, though, this expression is used more generally. It refers to any situation where there’s a catch, where there’s no solution, where there’s no way out. One more bit of rmation about the expression catch-22, about the number 22 in the expression. This number doesn’t have any real meaning; it just signifies one in a long line of catches. Heller really could have used any number; it didn’t have to be 22. When Heller was first writing the book, he used the number 14; the book was originally titled Catch-14. Then, in the production process, the number was changed to 18, so the title was Catch-18. But then there was a problem with the number 18 because there was another book with 18 in the title, so Heller’s title became Catch-22. Hemophilia is a condition in which the blood either clots slowly or fails to clot at all. Most people who get a little cut on a finger can put a bandage on the cut, and the cut on the finger will heal because the blood will clot. A blood clot forms from the polymerization of protein fibers that circulate in the blood. A number of protein factors take part in the process, and it is necessary for all of the protein factors to function correctly for blood to clot. Hemophilia exists when any of the factors is either missing or not functioning. The most mon kinds of hemophilia are hemophilia A or classic hemophilia and hemophilia B or Christmas hemophilia, which was named after the first person known to have contracted it. Hemophilia A occurs when clotting factor 8 is not functioning properly; 85% of those who suffer from hemophilia have hemophilia type A. Hemophilia B occurs when factor 9 is not functioning properly; almost all of the rest of those who suffer from hemophilia have hemophilia B. Hemophilia is generally passed from mother to son, though sometimes it seems to develop spontaneously in some women. Women carry recessive gene but do not generally develop the disease. A mother who carries the defective gene may or may not pass it on to her children. If a mother passes the defective gene to a daughter, the daughter will carry the gene but will most likely not develop the disease. If a mother passes the defective gene to a son, then the son will most likely develop the disease. Probably the most famous case of hemophilia is often called Royal hemophilia. In this case, Queen Victoria of England, who lived from 1819-1901, was a carrier of the mutating factor 8 that leads to hemophilia type A. Queen Victoria may have inherited the mutated gene from one of her parents, though there is no sign of the mutated gene in the families of Victoria’s parents up to that time that she was born. The mutated factor 8 may also have mutated spontaneously in Victoria, as seems to happen sometimes. However Victoria came to be a carrier of the gene with the mutated factor, she unfortunately passed it on to some of her children. She had nine children, and three of them, her daughters Alice and Beatrice and her son Leopold, received the mutated gene from their mother. Victoria’s daughters then intermarried with other royal houses of Europe and carried the disease with them. Through Queen Victoria’s daughter Beatrice, the disease was carried into the royal family of Spain. Through Queen Victoria’s daughter Alice, the disease was introduced into the royal families of Austria and Russia, though the disease no longer exists in the Russian family because Victoria’s granddaughter Alexandra and her children were all killed during the Russian revolution.

Now, we need use new technique to improve the management method for enhancing management level. Taking “National Western Surveying and Mapping Project on 1:50000 Topological Maps Blank Area” as an example, this paper focus on production planning management. The project is remarkable, not only the task and extent is tremendous, but also the staff and stuff are excessive. The Blank Area has atrocious weather and extreme hypsography.

INTRODUCTIONNowadays, Geographical Information Systems(GIS) are powerful and useful as means of information, visualization and research tools(Quan Bao,2004). Most GIS sofare is more suited to providing limited types of output than as a tool to support, at anything other than a superficial level, tactical or strategic decision-making processes. To improve the usefulness of GIS as a decision support tool, o needs are apparent. First, decision-makers require methods that allow them to easily select alternatives across a number of relevant criteria. Second, it is necessary to explicitly recognize that most decision-making processes involve multiple participants. Since problem solving id often characterized by multiple and conflicting objectives, methods that contribute toward more a pletely aiding decision system are required.。
