Artifical Blood essays

Artifical Blood essays Every 3.7 seconds someone in the United States is receiving a blood transfusion and a total of thirty million units of blood is transfused throughout the world annually (Cannell 1999)1. In the 1600s Louis XIV physician, Jean-Baptiste, performed the first blood transfusion when he took nine ounces of lambs blood and placed it into a teenage boy. Not only were blood transfusions experimented with on humans but animals too. For example, the English used dogs in their experiments transfusing urine, milk, wine, and other substances. Each of these scientific explorations was all towards accomplishing one goal, to find a substitute for human blood. For decades, scientists have chased the elusive dream of creating artificial blood-blood that would be universally compatible and readily available-and today a handful of U.S. companies is tantalizing close to the finish line (Cimmons 2001)2. Three Bio-tech American companies; Northfield Laboratories, Biopure Corp, and Alliance Pharmaceut ical Corp and a Canadian company, Hemosol are fighting for the recognition to be the first group to have an approved blood substitute sold in the United States. The companies are striving for a substitute that could decrease the blood shortages, and save the lives of millions by providing blood with no contaminations and eliminating the time spent searching for donor blood that is compatible, a potential billion-dollar industry. Blood is essential for the well being of humans. Blood carries the oxygen and nutrients that the body digests from food and carries them to every cell in the body. It also is responsible for removing carbon dioxide and other waste materials from the body. Blood is also essential for forming white blood cells that attack foreign agents in the body, such as bacteria and viruses. Inside one red blood cell there are approximately 280 million hemoglobin protein molecules. It is these molecules that abs...

12 Classic Essays on English Prose Style

12 Classic Essays on English Prose Style Despite the changes in English prose over the past few centuries, we may still benefit from the stylistic observations of the old masters. Here, chronologically arranged, are 12  key passages from our collection of Classic Essays on English Prose Style. (To read the complete essays, click on the highlighted titles.) Samuel Johnson on the Bugbear StyleThere is a mode of style for which I know not that the masters of oratory have yet found a name; a style by which the most evident truths are so obscured, that they can no longer be perceived, and the most familiar propositions so disguised that they cannot be known. . . . This style may be called the terrifick, for its chief intention is, to terrify and amaze; it may be termed the repulsive, for its natural effect is to drive away the reader; or it may be distinguished, in plain English, by the denomination of the bugbear style, for it has more terror than danger.(Samuel Johnson, On the Bugbear Style, 1758) Oliver Goldsmith on Simple EloquenceEloquence is not in the words but in the subject, and in great concerns the more simply anything is expressed, it is generally the more sublime. True eloquence does not consist, as the rhetoricians assure us, in saying great things in a sublime style, but in a simple style, for there is, properly speaking, no such thing as a sublime style; the sublimity lies only in the things; and when they are not so, the language may be turgid, affected, metaphoricalbut not affecting.(Oliver Goldsmith, Of Eloquence, 1759) Benjamin Franklin on Imitating the Style of the SpectatorAbout this time I met with an odd volume of the Spectator. I had never before seen any of them. I bought it, read it over and over, and was much delighted with it. I thought the writing excellent, and wished, if possible, to imitate it. With that view, I took some of the papers, and making short hints of the sentiment in each sentence, laid them by for a few days, and then, without looking at the book, tried to complete the papers again, by expressing each hinted sentiment at length and as fully as it had been expressed before, in any suitable words that should come to hand.(Benjamin Franklin, Imitating the Style of the Spectator, 1789) William Hazlitt on Familiar StyleIt is not easy to write a familiar style. Many people mistake a familiar for a vulgar style, and suppose that to write without affectation is to write at random. On the contrary, there is nothing that requires more precision, and, if I may so say, purity of expr ession, than the style I am speaking of. It utterly rejects not only all unmeaning pomp, but all low, cant phrases, and loose, unconnected, slipshod allusions. It is not to take the first word that offers, but the best word in common use.(William Hazlitt, On Familiar Style, 1822) Thomas Macaulay on the Bombastic Style[Michael Sadlers style is] everything which it ought not to be. Instead of saying what he has to say with the perspicuity, the precision, and the simplicity in which consists the eloquence proper to scientific writing, he indulges without measure in vague, bombastic declamation, made up of those fine things which boys of fifteen admire, and which everybody, who is not destined to be a boy all his life, weeds vigorously out of his compositions after five-and-twenty. That portion of his two thick volumes which is not made up of statistical tables, consists principally of ejaculations, apostrophes, metaphors, similesall the worst of their respective kinds.(Thomas Babington Macaulay, On Sadlers Bombastic Declamations, 1831) Henry Thoreau on a Vigorous Prose StyleThe scholar might frequently emulate the propriety and emphasis of the farmers call to his team, and confess that if that were written it would surpass his labored sentences. Whose are the t ruly labored sentences? From the weak and flimsy periods of the politician and literary man, we are glad to turn even to the description of work, the simple record of the months labor in the farmers almanac, to restore our tone and spirits. A sentence should read as if its author, had he held a plow instead of a pen, could have drawn a furrow deep and straight to the end.(Henry David Thoreau, A Vigorous Prose Style, 1849) Cardinal John Newman on the Inseparability of Style and SubstanceThought and  speech  are inseparable from each other. Matter and expression are parts of one;  style  is a thinking out into  language. This is what I have been laying down, and this is literature: not  things, not the verbal  symbols  of things; not on the other hand mere  words; but thoughts expressed in language. . . .  A great author, Gentlemen, is not one who merely has a  copia verborum, whether in prose or verse, and can, as it were, turn on at his will any number of splendid  phrases  and swelling sentences; but he is one who has something to say and knows how to say it.(John Henry Newman, The Idea of a University, 1852) Mark Twain on Fenimore Coopers Literary OffencesCoopers word-sense was singularly dull. When a person has a poor ear for music he will flat and sharp right along without knowing it. He keeps near the tune, but it is not the tune. When a person has a poor ear for words, the result is a literary flatting and sharping; you perceive what he is intending to say, but you also perceive that he does not say it. This is Cooper. He was not a word-musician. His ear was satisfied with the approximate words. . . . There have been daring people in the world who claimed that Cooper could write English, but they are all dead now.(Mark Twain, Fenimore Coopers Literary Offences, 1895) Agnes Repplier on the Right WordsMusicians know the value of chords; painters know the value of colors; writers are often so blind to the value of words that they are content with a bare expression of their thoughts . . .. For every sentence that may be penned or spoken the right words exist. They lie concealed in the inexhaustible wealth of a vocabulary enriched by centuries of noble thought and delicate manipulation. He who does not find them and fit them into place, who accepts the first term which presents itself rather than search for the expression which accurately and beautifully embodies his meaning, aspires to mediocrity, and is content with failure.(Agnes Repplier, Words, 1896) Arthur Quiller-Couch on Extraneous Ornament[L]et me plead that you have been told of one or two things which Style is not; which have little or nothing to do with Style, though sometimes vulgarly mistaken for it. Style, for example, is not- can never be- extraneous Ornament. . . . [I]f you here requ ire a practical rule of me, I will present you with this: Whenever you feel an impulse to perpetrate a piece of exceptionally fine writing, obey it- wholeheartedly- and delete it before sending your manuscript to press. Murder your darlings.(Sir Arthur Quiller-Couch, On Style, 1916) H.L. Mencken on Woodrow Wilsons StyleWoodrow knew how to conjure up such words. He knew how to make them glow, and weep. He wasted no time upon the heads of his dupes, but aimed directly at their ears, diaphragms and hearts. . . . When Wilson got upon his legs in those days he seems to have gone into a sort of trance, with all the peculiar illusions and delusions that belong to a frenzied pedagogue. He heard words giving three cheers; he saw them race across a blackboard like Socialists pursued by the Polizei; he felt them rush up and kiss him.(H.L. Mencken, The Style of Woodrow, 1921) F.L. Lucas on Stylistic HonestyAs the police put it, anything you say may be used as evidence against you. If handwriting reveals character, writing reveals it still more. . . . Most style is not honest enough. Easy to say, but hard to practice. A writer may take to long words, as young men to beards- to impress. But long words, like long beards, are often the badge of charlatans. Or a writer may cult ivate the obscure, to seem profound. But even carefully muddied puddles are soon fathomed. Or he may cultivate eccentricity, to seem original. But really original people do not have to think about being original- they can no more help it than they can help breathing. They do not need to dye their hair green.(F.L. Lucas, 10 Principles of Effective Style, 1955) For the complete collection, visit Classic Essays on English Prose Style.

Presently, if one has an adequate amount of financial resources one can improve their physical appearance.

Financial Management Essay Example | Topics and Well Written Essays - 2000 words - 5

Financial Management - Essay Example This paper will explore the different ways by which business entities can deal with the exchange rate variations to protect the value of their assets and profits against unpredictable risks. In recent years derivatives have been developed in order to provide some sort of insurance in the face of uncertainty caused by the changes in the foreign exchange rates. Derivative, or hybrid, investments, unlike stocks and bonds, do not represent ownership of shares, such as stocks, or a promise of loan repayment, such as bonds, and are once or twice removed from a real product. For example, a crude oil futures contract is a bet on which way crude oil prices will move, but what happens to the product itself is of no interest to the investor When an individual converts one currency into another in an actual exchange, the risk inherent in this activity is called a transaction exposure. Multinationals often face translation exposure, or the risk that arises from the need to re-state one currency in terms of another currency for accounting purposes. The risk arises because exchange risk volatility can impact the value of net assets and profits at the time of their translation. (See Kolb 1997). Financial derivatives are based on an underlying instrument such interest as debt instruments or foreign currencies. Most predominant among these derivatives are forward contracts, but futures contracts, option contracts, and swap contracts are also used by businesses as means of hedging. Hedging is distinguished from speculation in that the hedger wants to shift risk to others while the speculator hopes to make profits for the risk he is taking. A futures contract is an agreement that one party will accept delivery of a particular asset – either real or financial – on some date in the future at a price determined today. If one is intending to buy an asset in the future, one could buy a futures contract (a long position) today to fix the

Creation Or Evolution Essay -- essays research papers

EVOLUTION OR CREATION? In a coherent world like ours people are questioning their religion and not knowing whether to believe in creation by God or evolution, Through out my research I have found four possible answers to this question to incorporate both theories . Which prove neither wrong and belief in both at the same time One approach would be to believe that when God when created the trees in 4004 BCE, he would have formed them complete with growth rings. So too with other plants, animals and minerals. Everything in the world would then appear as if they had existed in the period of time prior to creation. In other words, God created the world as if it has had a past. One would interpret the evidence to show that the world was created only a few thousand years ago, but that it was created looking as if it had evolved over billions of years . A second approach would involve a relatively small change in the belief system of the "Genesis believing" creation scientists. The change would be to accept the Genesis account of creation as God's initial creation message which He revealed to the ancient Israelites who lived in a pre-scientific age. This would have been the only type of explanation that they could understand at the time. This would require one to abandon the literal interpretation of Genesis in favor of the belief that it is a historical myth. One could argue that Jesus used parables to make a point about human nature; the parables did not necessarily ...

Marriage relationships are increasingly more equal

It is true that marriage relationships are becoming increasingly equal, but to an extent. Since the early 1900's the stereotypical ‘housewife' role has changed, dramatically. This allowed men to try out, on what would have been seen as ‘Women jobs' such as childcare, cooking and cleaning, and also women to do some ‘Men jobs' which were mainly ‘behind the computer' jobs and more leisure time, women also had a say in purchases and money matters, something which would have not been possible without this experience in change of gender roles. Young and Wilmott were functionalist sociologists who came up with a theory that; ‘Marriage roles are becoming more equal.' They called this the Symmetrical family, this is when the husband and wife have similar roles and share tasks and work equally. They claimed to have proven this theory by interviewing 1700 or more women and only asking them one question which was â€Å"Did you're husband contribute to housework at all this week?† Ann Oakley criticised Young & Wilmot's methodology as her personal views were extremely diverse to theirs. She concluded it could vary from a miniscule to a large amount, making it unfair. The people who get interviewed are only allowed to answer ‘Yes Or No' this makes it really hard to know as no additional details are included such as; when did they do this, how often do they do this and how they contribute to the change in stereotypical gender roles. After Ann Oakley Criticised Young & Wilmot's theory, she made her own theory. She divided her questionnaires into four groups, which consisted of; Housework, Childcare, Decision making and leisure. Ann Oakley states that women are increasingly becoming more equal to their husband, but they are unfortunately still doing 70% of all housework. This portrays that, women are more equal in decision making, work and the outside life but still in their stereotypical gender role at home, with housework and child care. She also states that men only contribute to nice, easy, clean and enjoyable things within the household and childcare; such as playing with the children, purchasing them toys or gifts, sending them to parks, washing one plate once in a whilst and may also cook occasionally. However, they never seem to be cleaning up the house, changing dirty nappies or even cleaning up the children's sick or mess. These are all unfortunately left for the ‘housewife' to do. Overall, Ann Oakley has successfully proved that Young and Wilmott are incorrect in their conclusions on ‘marriages becoming more equal within the household,' because of their imprecise interviewing techniques on collecting data. However, research shows that marriages are increasingly becoming more equal in the household, even though it is increasing slowly.
