Lasers in Surgery Essay -- Exploratory Essays Research Papers

Lasers in Surgery      Ã‚  Ã‚  Ã‚  Ã‚   Abstract: The laser is gaining increasing popularity in the medical field because of its broad application, efficiency, and improvement in overall ease of the procedures in which it is used.. The laser can treat an enormous range of ailments. The chronic nighttime snorer can give those around him relief by a simple procedure with the laser. In dermatology, the laser can be used for removing moles, tattoos, birthmarks, treating wrinkles, and possibly destroying skin cancer. The once dreaded trips to the dentist may become less painful since the laser is helping to replace the drill and Novocain. The laser also is becoming increasingly popular in orthopedics for treating shoulder, knee, and back ailments. For women many gynecological problems ranging from infertility to endometriosis can be treated with the laser. For small, precise work the laser is indispensable such as in the eye. Unfortunately, since laser medicine is still rapidly developing, it h as experienced its pitfalls in some areas like cardiology. Overall, the laser is an invaluable substitute for the scalpel of the past, and the laser's possibilities for the future are broad and promising.    Lasers in Surgery The laser is creating a bloodless revolution. A laser works by using heat to obliterate cells. As it cuts, blood vessels are sealed, and tissue is sterilized. The laser is particularly useful in regions of the body that are difficult to reach. Many types of lasers are used in surgery, and the kind (gas, liquid, solid, visible, or unseen) varies based on the procedure. Choosing the laser to fit the procedure is essential because otherwise damage such as fires, eye harm, a charred cheek, a chipped t... ...ion to use lasers at local hospitals are generally reputable.    Laser surgery is a pioneering field of medicine. The laser is used for some type of procedure in practically every specialty field. Doctors are researching the laser for even more increased use because it provides a noninvasive, quicker, and less painful approach to many procedures. In the future, the laser will become an increasingly common place medical tool.    Bibliography "Laser Surgery Can Stop the Noise." USA Today February 1995: 14-15. McCarthy, Laura Flynn.

How Is Science Combating Food Shortages in Africa Essay

Africa has been fighting a constant battle against starvation for decades. What with an uncontrollably growing population and harsh dry climate, its no wonder that not only Africa, but the world could be in for a big crisis: the lack of food. With over 7 billion people in this world to feed, one billion in Africa, its a wonder that our planet can support this mass population, and the situation is going to get much worse unless there is a solution as to how the shortage of food can be fixed. Since the 1970’s, scientists have experimented with Genetically Modified foods (GM foods). That means that they’ve changed the organisms, and the DNA, in order to enhance some aspects of the food or fix any possible faults. So far, GM organisms have proved to increase food production, which is a relevant and effective solution. This solution has indeed raised arguments, creating economical, ethical and societal implications. Genetically modified foods could be the solution to save Africa from the endless starvation and malnourishment. It offers something completely new; it is a biotechnical solution that is different to any other option considered to aid those suffering from the lack of food in Africa. GM crops grow faster, produce much more, need less time and less labor. It would be a permanent solution. Unlike transferring food across the oceans in order to give aid, GM foods would be able to be produced in the countries that actually will need and use them, instead of relying on other wealthier nations to bring it to them. This would also teach these less developed countries how to manage on their own, and not being supported or aided by the more economically developed countries. Even more positive aspects of this solution are, that these GM crops have longer shelf-life, meaning that they do not have to be consumed immediately, but they can be stored for longer. Furthermore; they don’t require as many natural resources and materials as normal crops, which is good cause Africa itself doesn’t offer that many, which is one of the reasons as to why it’s in the situation that it is in right now. This would give an exceptional amount of aid and hope to the people of Africa as it would fix one major issue that has been developing throughout the years, and help them defeat other problems that their nations are facing. However, there are always downsides to these new inventions. Firstly, GM foods haven’t been in the know for long enough to know if they have any side affects that humans should be concerned of. Many people resist the idea of genetical modification because of this uncertainty. The foods and crops could always trigger allergic reactions, which might be fatal in nations that offer poor medical aid, or any health impacts for humans and even animals. However, the certainty that these problems exist is only an assumption. For as far we know, there might be no bad consequences or effects that GMO’s might bring. Another issue is how this will work in the nations of Africa. The leaders of the nations might decide that this is an uncertain and doubtful solution, that might only bring harm to their countries. Or some nations might fear change, even if it could help the starvation issues that they’re struggling with. The only thing that the developed nations could do in this case, would be to try and negotiate as to how this solution can help them, not only temporarily but in the long run as well. Also, it will be a very cheap solution, which will be a major attraction to many nation as their economical situations aren’t that great. Furthermore, the annual cost of individuals having to purchase the genetically modified seeds will be an issue, as the continent is generally very poor. The effect of growing and consuming genetically modified crops is still unknown, however many possible and realistic assumptions have been made. A possible dilemma is the harm that these organisms could cause to other organisms in the nature. For an example, the mortality rate of monarch butterfly caterpillars has gone up recently, due to the wind blowing pollen from genetically modified B.t corn to milkweed plants, that the caterpillars consume. A nature study was held in order to find out whether this was true or not, and the results were in fact pointing towards the pollen being the cause of death. There are also countless other victims of genetic engineering, however they cannot be prevented as the toxins that kill the pests are also harmful to other insects. Unfortunately, in order to grow healthy crops without a financial loss, the use of these B.t toxins is essential. Another issue that could arise from this is cross-breeding of these herbicide tolerant crops and the weeds themselves, resulting in a ‘superweed’ that would be immune to these toxins. That could cause in mass destruction of crops and a great financial loss to the farmers, as well as an unnatural new specie. An issue that could arise within the use of GM crops is the strain on the economies of the nations using them. It would be quite expensive to transport the GM foods across the globe, and it would also take some time. Also, the cost of these seeds can be expected to rise due to the technology used to create them. A more developed country and farm could possibly afford the annual cost of these crops, however a less economically developed country cannot. A solution for this problem could be funding the production and research of GM foods. An example of such a funder is the Rockefeller Foundation, who has founded the research and production of genetically modified rice. GM rice would be a very costly process but with the help of funders and other wealthy companies the cost of expense can be reduced. Since the population of already 7 billion is estimated to almost double in the upcoming 50 years, the worlds biggest dilemma at the moment is to find a solution as to how to feed all these people and how our natural resources won’t be all used up. GM crops is one of the many solutions thought to solve this problem, however, like the rest of them, it comes with many different positive and negative aspects. Furthermore, since it is such a new invention, and not a lot of research has been done yet, the effects and consequences are unknown. If the massive population growth could be stalled for a few decades, say by introducing a one-child-policy, then the development of solutions such as GM crops could be completed meanwhile. This would be a really effective way to provide food aid to the peoples of the world, especially Africa, in order to defeat hunger and starvation, and it would also slow down the growth of the population, maybe even declining it.

Feminine Mystique by Betty Friedan Started It All

'Feminine Mystique' by Betty Friedan 'Started It All' The Feminine Mystique by Betty Friedan, published in 1963, is often seen as the beginning of the women’s liberation movement. It is the most famous of Betty Friedan’s works, and it made her a household name. Feminists of the 1960s and 1970s would later say The Feminine Mystique was the book that â€Å"started it all.† What Is the Mystique? In The Feminine Mystique, Friedan explores the unhappiness of mid-20th century women, describing women’s unhappiness as â€Å"the problem that has no name.† Women felt this sense of depression because they were forced to be subservient to men financially, mentally, physically, and intellectually. The feminine â€Å"mystique† was the idealized image to which women tried to conform despite their lack of fulfillment.   The Feminine Mystique explains that in post-World War II United States life, women were encouraged to be wives, mothers, and housewives- and only wives, mothers, and housewives. This, Friedan says, was a failed social experiment. Relegating women to the â€Å"perfect† housewife or happy homemaker prevented much success and happiness, among the women and, consequently, their families. Friedan writes in the first pages of her book that housewives were asking themselves, â€Å"Is that all?† Why Friedan Wrote the Book Friedan was inspired to write The Feminine Mystique when she attended her Smith College 15-year reunion in the late 1950s. She surveyed her classmates and learned that none of them was happy with the idealized housewife role. However, when she tried to publish the results of her study, women’s magazines refused. She continued working on the problem, the result of her extensive research being The Feminine Mystique in 1963.   In addition to case studies of 1950s women, the book observes that women in the 1930s often had education and careers. It wasnt as if it had never occurred to women over the years to seek personal fulfillment. However, the 1950s were a time of regression: the average age at which women married dropped, and fewer women went to college. Post-war consumer culture spread the myth that fulfillment for women was found in the home, as a wife and mother. Friedan argues that women should develop themselves and their intellectual abilities and fulfill their potential rather than making a â€Å"choice† to be just a housewife. Lasting Effects of 'The Feminine Mystique' The Feminine Mystique became an international bestseller as it launched the second-wave feminist movement. It has sold more than a million copies and been translated into multiple languages. It is a key text in Women’s Studies and U.S. history classes. For years, Friedan toured the United States speaking about The Feminine Mystique and introducing audiences to her groundbreaking work and to feminism. Women have repeatedly described how they felt when reading the book: They saw that they were not alone, and that they could aspire to something more than the life they were being encouraged or even forced to lead. The idea Friedan expresses is that if women escaped the confines of â€Å"traditional† notions of femininity, they could then truly enjoy being women. Quotes from 'The Feminine Mystique' Here are some memorable passages from the book: â€Å"Over and over again, stories in womens magazines insist that women can know fulfillment only at the moment of giving birth to a child. They deny the years when she can no longer look forward to giving birth, even if she repeats the act over and over again. In the feminine mystique, there is no other way for a woman to dream of creation or of the future. There is no other way she can even dream about herself, except as her childrens mother, her husbands wife.†Ã‚  Ã¢â‚¬Å"The only way for a woman, as for a man, to find herself, to know herself as a person, is by creative work of her own.†Ã‚  Ã¢â‚¬Å"When one begins to think about it, America depends rather heavily on womens passive dependence, their femininity. Femininity, if one still wants to call it that, makes American women a target and a victim of the sexual sell.†The cadences of the Seneca Falls Declaration came straight from the Declaration of Independence: When, in the course of human events, it becomes necessary for one portion of the family of man to assume among the people of the earth a position different from that they have hitherto occupied. . . . We hold these truths to be self-evident:that all men and women are created equal.†

‘A person can only have a meaningful life if they believe in God’ Essay Example

‘A person can only have a meaningful life if they believe in God’ Essay Example ‘A person can only have a meaningful life if they believe in God’ Essay ‘A person can only have a meaningful life if they believe in God’ Essay Nowadays, as our society becomes increasingly secularised and the number of people who believe in Christianity and other religions is dropping, the question of the benefits of believing in Christianity is an important, and specifically, if believing in Christianity and thus God helps you live a rewarding and meaningful life.A large proportion of Christians, such as Fundamentalists and Conservatives, would believe that Christianity is the only way to live a meaningful life. This is because God gives our lives purpose as he has a plan for everyone. He has given us the gift of life and therefore we should be thankful for this and therefore show faith through regularly going to church and praying. As Conservatives and Fundamentalists believe that God is the only way for salvation, belief in God would cause them to evangelise and spread the word of God to other non-believers so that they can be blessed by God as well. Liberal Christians are more open to the idea of the Anonymous Christian (a person who lives a moral life but has not experienced Christianity)), although they would still try to convert others to Christianity. I believe that this a strong reason showing that God helps you live a meaningful life, although this only is effective for someone who already believes in God and so does not apply to non-believers.Christianity provides a strong moral framework for people to live their lives. Fundamentalists will look to the Bible to form their opinions about different issues and they will try to spread the word of God. Conservative Christians will look to the Church for guidance and might perhaps follow Natural Law. More Liberal Christians will believe that the New Testament message of agape and situation ethics are the most important thing and so not only will they be kind to all other people, they would also use this and apply it to certain areas of live, such as relationships and their opinion on abortion. Although Christians would regard this as the English heresy, Christianity does provide a good moral standpoint for how someone should live their lives, and so I believe that even if you don’t believe in God, Christianity can still help you lead good and fulfilling lives.There are also many things that can’t be explained by science and so if you believe in Christianity, you can have a greater understanding of the world around us. For instance, Science still does not fully understand the Creation of the Universe and so if you combine the two, then you can understand God and his creation better as they are complementary questions: science answers the how and religion answers the why. Conservatives might look to the Pope for guidance who believes that science and religion are complementary.For these reasons I think that as long as you live a life with good Christian morals, I do not think you have to believe in God, although as stated by Pascal’s wager, the consequences if you are wrong and God does exist outweigh the disadvantages that come with belief in God.

Genetically Modified Foods Research Paper Example | Topics and Well Written Essays - 500 words

Genetically Modified Foods - Research Paper Example However, despite the perceived benefits of reengineering foods, debates have ensued on the safety of genetically modified foods with critics arguing that such food could pose health risks to human beings. This essay expounds on genetically modified foods. Researchers have identified that people’s choice of consuming such foods is influenced by attitudes, pragmatic considerations, and personal circumstances. Although some people desist from GM products with no facts, researchers have identified that the foodstuffs may have some negative effects. The effects touch on environmental hazards, human health risks, and economic consequences. For instance, some of the genetically modified crops have caused damage to other organisms. Genetically modified foods may also cause allergy to some people that may be fatal (Forman, 2010). There have been cases of allergy development in children across Europe and the United States to foods such as peanuts. The process of establishing GM foods and the eventual presentation to the market has been long with substantial use of resources. Researchers and consumer advocates have claimed that this may lead to unbearable seed prices. Genetically modified foods have numerous advantages. For example, genetically modified foods are resistant to cold and plants, such as tobacco, strawberries, and potato have been modified to be resistant to frost by the introduction of the antifreeze gene. The antifreeze genes enable plants withstand the low temperatures, thus allowing crop production to take place throughout the year (Edwards, 2010). Nutritional improvement is another positive aspect of genetically modified foods. The genetic modification of foods is appropriate because food like rice, which is a common diet in most countries could be modified genetically and supply the essential nutrients that will enable individuals feed on a balanced diet. This will also aid in

'French argues that 'An awareness of the impact of (national) culture Essay - 1

'French argues that 'An awareness of the impact of (national) culture on people in work organisations' is important in tod - Essay Example According to Samovar et al (2009), culture has been subjected to numerous and often-complex abstract definitions as writers labored to incorporate and explain array of cultural components and objectives. They continue to say that, what was considered earliest definition of culture by British anthropologist Sir Edward Burnett Taylor in 1871, explained culture as â€Å"the complex whole which includes knowledge, belief, art, morals, law, custom, and any other capabilities and habits acquired by a man as a member of society (Tylor, 2007) Blad (p. 7) explains that, it is important to note that the characteristic that define state autonomy and global market integration are found in both cases. He continues to say that, the comparison of inter-related state-building projects allows us to not only understand the role of distinct national culture but also how sub-state autonomy is enhanced through global political economic integration. According to Entezar (2008, p. 24-25) ‘culture ca n be studied in two different ways. One can either study specifics in order to determine the general patterns (inductive) or study the general patterns to identify the specifics of a culture (deductive). The second approach is adopted by Hofstede in his dimensional analysis of culture.’ She continues to explain that, ‘every culture deals with power ambiguity, individualism, and gender that are universal and exist in all cultures. Here again these dimensions are filtered through the value systems of various cultures.’ In the argument that, â€Å"awareness of the impact of national culture on people in work organizations and its importance in today’s world†, I will argue for it. Theories of National Culture Ernest Gellner’s theory of nationalism, initially articulated in a chapter of Thought and Change in 1964, rigorously questioned the putative casual power of a pre-existing culture in formation of nations and nationalism. In what is now a fam ous reversal of commonsensical understandings of the relationship between culture and nationalism, he insisted no â€Å"the nation†, a bounded national culture that creates nationalism, but the other way round. (Hall et al 2010, p. 516) Lussier & Achua (2010: pp 391) explains that whether organizational or national, culture is a product of values and norms that people use to guide and control their behavior. Culture affects the relationship between members and leaders of a nation based on shared values. They continue to explain that, on national level, a country’s values and norms determine what kinds of attitude and behaviors are acceptable or appropriate. The people of a particular culture are socialized into these values as they grow up, and norms and social guidelines prescribe the way they should behave toward one another. From the above explanation by Lussier and Achua, we can see that, in a nation, a specific conduct that people should relate to each other, ther e is a specific way that people in management position should relate to their subjects. These codes of conduct dictate how they relate and behave. For instance, the eastern countries, they have a unique dressing manner. In that, all women should be in a certain type of cloth. The same is seen in other countries with Islam religion. Another example is the African countries; the traditional Africans had a unique way of dressing their leaders with different types of clothing. The leaders could be donned with animal skin, to
