Is Abortion Considered The Taking Of Human Life Philosophy Essay

Is Abortion Considered The Taking Of Human Life Philosophy Essay An abortion refers to the premature termination of a pregnancy. (Thiroux Krasemann 2009, p254). Many ethical issues arise from abortion, however the main ones to be discussed are regarding whether or not abortion is considered the taking of human life, and whose decision is it to determine whether or not they should be permitted. Ultimately, the most significant concepts surrounding abortion relate to the Value of Human Life and The Principal of Individual Freedom. The Value of Life refers to the idea that our lives are a basic possession. Every person experiences their own lives in a unique way, and no-one can truly live anothers life. Each individual must be treated as unique, however this does not discard the concept that ending of a human life cannot be justified, rather it is believed it should not be ended without very strong justification. Consequently, it is deemed morally wrong to end a persons life against their will. The Principal of Individual Freedom basically states that as individuals, we must possess the freedom to choose our own ways and means of being moral within the framework of the other four principals. Because no person or situation is exactly like another, there must be some freedom for those people to deal with these different circumstances in a manner that best suits them (Thiroux Krasemann 2009). Pro-Life and Pro-Choice There are two extreme views concerning abortion, and these are the ones of pro-life (against abortion), and pro-choice (permit abortion). The first view is that of Pro-Life, who ultimately believes that the conceptus has an absolute right to life, and this is where the Value of Life Principal arises. There are certain key stages in the conceptuss development which reinforce this belief, these include the following; By the third week, the embryo is developing various parts and a week later its heart begins to beat. Continuing to week five, divisions of the brain occur and the development of eyes and limb buds appear. By the seventh and eight week, sexual characteristics can be recognised, there is some lower brain anatomy and the fetus has developed some reflex reactions. Therefore, since ultimately their genetic view that life begins at conception, abortion is associated with murder, as it is the act of taking human life. Pro-lifes arguments are based on the value of life, that is, the right to life is absolute, especially the right of unborn life and its innocence. Thus, every unborn child should be regarded as human and receive all rights deserved from the moment of conception onwards (Thiroux Krasemann 2009). Whether we believe that the fetus is a person or not, its debatable that a woman has some sort of ethical responsibility to the fetus. Also, abortions further along in the pregnancy are even more heavily concerned with the assumption of taking a human life because they feel there is something very human about the fetus as its development has continued (Ethics of Abortion 2010). There are a number of other issues concerning abortion, for instance, the medical and psychological effects of abortion on women are harmful, the dangers of pregnancy are almost irrelevant because of technological advances therefore abortions are unnecessary, there are alternatives to an abortion such as adoption, and the belief that women must accept full responsibility for their actions and innocent life cannot be sacrificed if they fail to do so through their own carelessness. Even when it comes to rape, destruction of innocent unborn human life is still not justified. (Thiroux Krasemann 2009, p262). Pro-life believe that if women want complete control over their body, then control should include using contraceptives to avoid unwanted pregnancies. Therefore, if a woman fails to use these measures and falls pregnant, she must bear the responsibility and consequences for her actions, rather than sacrificing human life (Women Issues 2010). The second extreme view is that of Pro-Choice, who are greatly in favour of abortion on request by the woman. Pro-choice believe that woman have absolute rights over their bodies, and the conceptus is part of a womans body until birth. (Thiroux Krasemann 2009, p272). Therefore, how can the conceptus be considered a human life before birth? This is where The Principal of Individual Freedom arises, where people should have a choice to determine what is best for them in their own circumstances. The argument continues with concerns of those fetuss which have been diagnosed with deformities, and therefore pro-choice believes that deformed children should not be brought into the world because of their burden on the health care system and ultimately society. This is also relative to children who are unwanted. Why bring a child into the world who is unwanted? What benefit does that place on the mother and also society? Especially if a woman is potentially an unfit mother, what kind of life would that leave for the child? (Thiroux Krasemann 2009). Adoption is considered an alternative to abortion by pro-life, however adoption is not always a solution and certainly are not as honourable as depicted. There are a number of adoption agencies that are down-right inhumane and surely no place for young children. In addition, when pregnancy results from rape or incense, the woman should never have to go through the birth because of the circumstances of the conception. Forcing a woman to go through the pregnancy as a result of such a violent act will just cause more psychological harm, and the child may be neglected and a reminder of the trauma endured (Women Issues 2010). It is difficult to relate to why people choose abortion if you dont have personal experience, or are personally associated with someone who does, therefore who are you to say they cannot have one? Pro-life are basically asking us to consider real life situations rather than vote on abstract potentially uninformed beliefs. (The Sydney Morning Herald 2010). Ultimately, abortion must be totally a matter of the womans choice and private decision and no one else should be able to interfere (Thiroux Krasemann 2009). Utilitarianism Applied to Abortion Utilitarianism refers to the ethical theory that everyone should perform that act or follow that moral rule that will bring about the greatest good (or happiness) for everyone concerned. (Thiroux Krasemann 2009, p42). When concerning abortion, it would seem to best apply the rule-utilitarianism, which refers to setting up a series of general morals and rules which can be applied to every moral question based, and when followed, yield the greatest good (Abortion: Ethical Analysis 2010). When this is applied to abortion, it can be argued that abortion is a completely ethical entity that will provide the most amount of happiness for the majority of people. This is reinforced by the statistics from the related newspaper article, which states, A survey of 1050 Australians investigating attitudes to early and late abortion published in the Medical Journal of Australia shows remarkably strong public support for women being able to access abortion at all stages of pregnancy, including after 24 weeks. (The Sydney Morning Herald 2010). An example of this view, is relative to a woman who may end up being an unfit mother to a child. If a 16-year old drug-addict were pregnant, would it not be in everyones best interest protect the child from the possibility of psychological and physical abuse, and ultimately a suffering lifetime? Pro-life views the situations concerning the fetus, where an abortion causes pain to the fetus and ultimately results in killing. However, from a utilitarian viewpoint, this focus on the fetus is unnecessary because its believed that the suffering involved can be avoided by an early abortion, that is before the fetus can develop the capability to undergo pain. Generally, the suffering of the fetus cannot be considered a strong argument against abortion (Utilitarian Org. 2010). In contrast, another view of utilitarianism is that the future life of the fetus would have had a probable balance of happiness over suffering, which is a definite argument against abortion, although not a dominant one. Another contrasting aspect is concerned with population size. If population decreases, utility will prescribe reproduction in order to increase it once again. This would create a shift will create the greatest of happiness to the most people. In this case, utility will generally oppose abortion. As a result of the views of a utilitarian, a general prescription either for or against abortion is extremely difficult to justify, as each case has its own significant and specific features (Utilitarian Org. 2010). Kants Categorical Imperative Kants Categorical Imperative basically emphasises that an act is immoral if the rule that would authorise it cannot be made into a rule for all human beings to follow. (Thiroux Krasemann 2009, p58). This is the belief that an act is considered to be moral solely because it adheres to a rule, therefore creating some sort of moral authority (Inquisitive 2010). A relative aspect of this theory concerns killing another human being. According to Kant, a person cannot kill another person being without violating a moral absolute. Therefore, killing is immoral and contradicts the Categorical Imperative, because essentially the meaning of life is to live (Thiroux Krasemann 2009). Kant also believes there must a universal morality that must be capable of being applied to every situation without exception (Inquisitive 2010). When Kants Categorical Imperative is applied to abortion, it is looking for the moral authority. According to this theory, Kant would state that, abortion is murder, rather than if you have an abortion, you are committing murder. However, Kant also believes in Good Will, which emphasises in doing the right thing, and consequences are irrelevant (Inquisitive 2010). Therefore, who is it to say that abortion is not doing the right thing under certain circumstances? In a number of different circumstances, as noted before, there are a number of situations where abortion may be the best and/or right thing to do. This may be relevant to women who are in danger if they continue with the birth, and the safer option would be to have an abortion. However, through this theory it is believed that if we condone abortion, then we are ultimately suggesting that killing is moral. Consequently, Kant is in favour that killing is moral and only under extreme consequences can it be justified (Thiroux Krasemann 2009). Conclusion In conclusion, the issues surrounding abortion are vast and there will always be those strongly opposed and in favour of the practice of it. With Kants Categorical Imperative, if everyone considered that abortion is moral, then we are condoning that essentially murder is moral. However, this encroaches on the rights we have as humans. Ultimately we believe we have control over our own bodies, therefore, who is it to say what we choose and believe is the best in our own interests? In my personal belief, I am ultimately on the side of pro-choice, as there could be detrimental effects if it ever became illegal. From a moral view, it is seen to be killing another person, however, there are certain circumstances that abortions are necessary or would be the best option concerning those involved. Especially with the circumstances of rape, I believe no one has the right to force an unwanted pregnancy that resulted from a traumatic experience. In addition, The Principal of Individual Freedom has the most effect as we all have our individual lives and what we consider to be most beneficial to us, should ultimately be established and not influenced or forced otherwise.

Acid Rain 10 :: essays research papers

Acid rain is exactly what it suggests- rain that is acidic. The definition of "acid rain" is rain with a pH of below 5.6. Rain becomes acidic because of gases that dissolve in the rain. Approximately 70% of acid rain is a result of dissolved sulfur dioxide (SO2) which forms Sulfuric Acid. The remaining 30% or so comes from various Nitrogen Oxides (mostly NO2 and NO3 which has collectedly adopted the mane Nox). There is also a small percentage of hydrochloric acid that makes up hydrochloric acid as well. The equation is as follows: Sulfuric acid when it joins with hydrogen atoms in the air: SO3(g) + H2O(l) = H2SO4(aq) In the air, the nitrogen ion becomes nitric or nitrous acid: NO2(g) + H2O(l) = HNO3(aq) + HNO2(aq) Sulfur dioxide is a colorless, prudent gas released as a by-product of combusted fossil fuels containing sulfur. What causes this is a variety of industrial processes, such as the production of iron and steel, utility factories, and crude oil processing. In iron and steel production, the smelting of metal sulfate ore produces pure metal. This causes the release of sulfur dioxide. Sulfur dioxide can also be emitted into the atmosphere ny natural disasters or means. This ten percent of all sulfur dioxide emission comes from volcanoes, sea spray, plankton, and rotting vegetation. The oxides of nitrogen are by-products of firing processes of extreme high temperatures, for example: automobiles, and utility plants; and in chemical industries, for example: fertilizer production, etc. Also, natural processes such as bacterial action in soil, forest fires, volcanic action, and lightning make up five percent of nitrogen oxide emission. Transportation makes up 43 percent, and 32 percent belongs to industrial combustion. There are a number of things that acid rain effects in our environment. Forests, soil, lakes, streams, rivers, materials, and essentially mankind. One of the most serious impacts that acid rain has on our environment is acid deposition on our trees and soil. When Sulfuric Acid falls on the earth in rain, nutrients in the soils are washed away. Some of the aluminum also present in the soil is released and can be absorbed by the roots of trees. This causes the trees to starve to death because they are deprived of their vital nutrients such as calcium and magnesium. Sometimes the sulfur dioxide doesn’t get converted to sulfuric acid. In fact, there is a large amount that can float into the atmosphere and return to earth unconverted.

Computer Manufacturing Industry Analysis

1. ENVIRONMENTAL ANALYSIS a. Definition of the Industry The following study presents a brief analysis of the Computer and Electronic Manufacturing Industry in the USA (NAICS 334 – North American Industry Classification System) with special focus on the Personal Computer’s sub-sector. I made the decision to focus on just one of the sub-sectors due to the large scope of the general industry. Industries in the Computer and Electronic Product Manufacturing subsector group establishments that manufacture computers, computer peripherals, communications equipment, and similar electronic products, and establishments that manufacture components for such products. † (Bureau of Labor Statistics) Given the previous description of the general Industry, I can now go further in the definition of the real point of study for this paper, which is the Computer Manufacturing, clustered in laptops, PC’s and servers. â€Å"This industry manufactures and/or assembles personal co mputers (PCs), laptops and servers.Operators typically purchase computer components (e. g. motherboards and graphics cards) from dedicated manufacturers in other industries† (IBIS World report 33441a, Semiconductor and Circuit Manufacturing). â€Å"This industry does not include tablet computers, nor does it include manufacturers of computer monitors, mice, keyboards and printers† (IBIS World report 33411b, Computer Peripheral Manufacturing). When covering the whole industry, â€Å"The US computer manufacturing industry includes about 1,200 companies with combined annual revenue of about $75 billion.Major companies include Dell, Hewlett-Packard, and IBM. † (Hoovers 2012) The computer manufacturing industry’s revenue is divided and measured according to each of the sub sectors that conform it. â€Å"Personal computers account for about 40 percent of industry revenue; mainframes and servers, 13 percent; and storage devices, about 10 percent. † (HOOVER S) While respecting to the sub-industry in which this paper is focused (PC’s, laptops and servers), and considering just the United States, it is conformed by 355 businesses generating annual revenue up to US$37 billion.Being the leading companies Hewlett-Packard, Dell and Apple. The total amount of units sold for the industry must be taken in consideration from the quantity of units shipped in the last year: Preliminary United States PC Vendor Unit Shipment Estimates for 4Q11 (Units) Company 4Q11 Shipments 4Q11 Market Share (%) 4Q10 Shipments 4Q10 Market Share (%) 4Q11-4Q10 Growth (%) HP 4,137,833 23. 1 5,598,619 29. 4 -26. 1 Dell 4,020,549 22. 4 4,210,000 22. 1 -4. 5 Apple 2,074,800 11. 6 1,718,400 9. 0 20. 7 Toshiba 1,925,100 10. 7 1,968,091 10. 3 -2. 2 Acer Group 1,756,838 . 8 1,982,477 10. 4 -11. 4 Others 4,014,644 22. 4 3,583,418 18. 8 12. 0 Total 17,929,764 100. 0 19,061,005 100. 0 -5. 9 Note: Data includes desk-based PCs, mobile PCs, including mini-notebooks but not m edia tablets such as the iPad.? Source: Gartner (January 2012) Comparing the studied sub-industry results with previous years, profit and revenue have been constantly decreasing and the annual growth in the last 5 years have been negative for the industry in about 5. 1%. Analysts from IBIS project that this will continue falling for the future 5 more years.Nonetheless, â€Å"The industry is capital-intensive: annual revenue per employee is about $460,000† (HOOVERS), while the whole Computer Manufacturing Industry in the US counts with approximately (in thousands) 1,099. 9 employees. b. Internal and External Analysis OPORTUNITIES -There is a growing consumer demand for PCs and tablets. -â€Å"Their rapid growth (of the market) suggests that they will become even more important to the economies of all three North American countries in the future† (Bureau of Labor Statistics 2012) -â€Å"The proliferation of cloud computing will prompt companies to increase their server investments† (IBIS 2012)THREATS -â€Å"Industry profit will continue to fall because of intense price competition† (IBIS World 2012) -â€Å"The  Computer Manufacturing industry  is being rapidly supplanted by imports, particularly from China. † (PR Web 2012) -Imports are a threat for local manufacturing revenue. â€Å"While import penetration in this industry stood at 50. 7% in 2007, imports are expected to satisfy an estimated 68. 6% of domestic demand in 2012,†Ã‚   (IBIS World 2012) -â€Å"While the emergence of new products and services will boost industry performance, US manufacturers are not expected to produce the required hardware (locally).

Customer Analysis The total domestic (US) annual demand for the industry by the end of 2011 was US$62. 2 billion. â€Å"The industry's woes cannot be blamed on a lack of demand. In fact, the share of US households that owns at least one computer increased by 7. 5 percentage points from 2007 to 2012. While demand has grown, fierce competition and widespread product homogeneity (the result of computers being assembled from standardized components) have led to falling prices and profit margins† (PR Web 2012)The identified target m arkets/segments for the Computer Manufacturing Industry are the following: 1. Large corporate customers (B2B) – Big companies 2. Small and medium size businesses (B2B) – Who represent about 20% of U. S. sales 3. Individual Customers and Consumers (B2C) – Who represent about 10% of U. S. sales 4. Public sector (government and educational) customers. 3. Competitors Analysis The computer manufacturing industry is highly concentrated within its most revenue-significant businesses due to the top 50 companies are responsible of about 90 percent of the total industry’s revenue. Competition from abroad has tightened profit margins and prices on mass-market computer systems. Consequently, most of the industry's largest players operate in several related industries to diversify their revenue sources, with a particular emphasis on the highly profitable enterprise segment and Information Technology (IT) services. † Currently, Hewlett-Packard (HP) and Dell are t he largest US-based computer manufacturers, followed by Apple. The total revenue and market share of personal computers for the last year, regarding the top 3 companies in the industry is: .

Executive Summary After this industry analysis, we can see that the computer manufacturing industry in the US is constantly loosing revenue and market share in the world. Almost every business in this Industry (top ranked) are loosing revenue and decreasing profitability. The only company that has increased revenue and has actually grown in the last five years is Apple.For this, I would recommend Apple’s executives to maintain their actual â€Å"Post-PC† strategy because it is known that demand for PC’s is decreasing while demand for oth er similar electronics such tablets is increasing and will continue doing so in the future. I would recommend Apple, as well, to focus a little bit also in extending their portfolio of offerings by including special services and solutions in order to attend the B2B market and gain some of their competitors share in this segment too.

Cry of Sodom

As indicated in the first part of the article, Nicholas Sensions settled in Connecticut in 1640 (Richard Godbeer, 1995). Eventually he established good relations in the community, since it was also stated that he settled down five years later, and founded a profitable enterprise in the community (Godbeer, 1995). At first glance, nothing outstanding seems to elevate itself from the norm.But what is empahtaically pointed out are the episodes of attempted attacks of Sensions against the male folk in the community for the act of sodomy (Godbeer, 1995). Apparently, the advances by Sensions were no isolated case, as the witnesses aver that the attempts were done over a 30-year span (Godbeer, 1995). What can be seen from the article? What draws one immediately is the topic itself, of a man attempting to have deviant sex with men in the community.But if one were to dig deeper, one could surmise the fact that people such as Sensions can lurk in one’s community virtually unnoticed. In t oday’s society, people are unaware that a sexual predator has invaded their communities with nary any notice. People such as Sensions have gotten too ensconced in the community that their real motivation in the area will go unnoticed until such attacks occur.People can hide under the cloak of â€Å"acceptability† then proceed to launch their nefarious acts against the very community that accepted them. The propensity of the act then by Sensions drew such an outburst that the court did not have a hard time to locate witnesses (Godbeer, 1995). In the same way, today’s society should also respond in like kind when these predators come into our communities. Reference Godbeer, R. (1995).

Unto Us Essays

Unto Us Essays Unto Us Essay Unto Us Essay Essay Topic: Poetry Spike Milligans Unto Us is one of his more serious poems that is about the issue of abortion or rather abortion for convenience. He adopts the persona of an unborn child which is unusual, yet effective method of narration, as it evokes sympathy from the reader. The poem tells the story of a child who is desperate for life but is murdered before he/she has a chance to live. The title of the poem Unto Us is taken directly from the phrase in the Bible: Unto us a child is born. This shortened version of the biblical reference is clever as it relates to the childs life being cut short. This is just one of the techniques used by the writer that makes it effective and I will be discussing these through the rest of the essay. The poem is split up into three sections: conception and leading up to the birth, abortion, and aftermath. The opening lines of the poem somewhere at some time they committed themselves to me suggests a fleeting moment; this certainly wasnt planned. It also implies that the parents have a duty and responsibility which is ironic considering the disregard they show towards the baby. The writer goes on to emphasise the babys existence by use of repetition and exclamations And so I was! Small but I WAS! This argues the point that an unborn child is still a human even in the early stages of development. The discovery of the child by the parents is totally void of any emotion:Soon they knew of me. My mother my fatherThe dash is used to signal a delay between the mother finding out and then the father. It also shows a lack of togetherness between the couple. The tone of this section is one of desperation and pleading quite obviously indicated by the last two lines:A silent Wait for me I will bring you love' This example of direct speech is used to make the character of the baby come alive. The second section of the poem starts with a pivotal sentence:I was taken This automatically changes the tone from desperation to anger. This change is aiming to stir up strong emotion. It changes the whole feel of the poem from life to death. This section deals with the abortion and how vulnerable the baby is: Blind, naked, defenceless The baby has been taken from its home against his will and all trace of it has been destroyed: and dropped on the sterile floor of a foot operated waste bucket It is as if the doctors couldnt care less about this baby by throwing it out like garbage. Section three is the aftermath, and what could have happened had the baby been born, it starts again with just how helpless the baby is: There was no Queens Counsel to take my brief This sets the tone to sadness and despair as the baby is ignored. The parents of the baby are wealthy enough to support it: The cot I might have warmed stood in Harrods shop window this highlights the main point of the poem- abortion for convenience. Obviously the writer is strongly against it but personally it did make me think a lot about this kind of abortion. It is clear the writer is trying to sway your view and does achieve this. The tone of the last few lines in the poem are very bitter: When my passing was told my father smiled A euphemism is used here as it is not considered murder by parents and it suggests accidental death. Also the sense of relief is apparent: [its] death was celebrated with tickets to see Danny la Rue who was pretending to be a woman like [its] mother was these lines question the womanhood of the mother in that would a real woman willingly murder her child? This poem was very interesting and thought-provoking as it tries to sway your views on abortion. I have looked at most of the techniques used by the writer in making this poem effective and have enjoyed writing about it.

Soviet Avant-Garde and Socialist Realism Essay Example | Topics and Well Written Essays - 1000 words

Soviet Avant-Garde and Socialist Realism - Essay Example This essay discusses that man with a Camera is a movie about its own production; it predicts the postmodern inclinations of what is nowadays meta-cinema. Vertov’s movies introduced a novel world of films to commemorate the brave universe of industrialized Soviet truth. The work concludes in Man With a Movie Camera which induces the sensory shower of the urban existence. It utilized strategies of visual comparison and associative montage so complex that they do not have names to date. There was a Whitman-esque documented-portrayal of the Soviet individuals, a self-impulsive dissertation on cinematic symbolism. It is devised to demolish habitual film watching by unveiling the ways in which the camera and movie editor create authenticity. Vertov’s masterwork had the extraordinary implication of emphasizing the spectator to recognize with the filmmaking procedure. Vertov’s ideology was that the camera was an innovation that assisted humans to investigate novel realms of the visual universe. The design that would best explore cinema’s potentialities would merge documentary as well as cinematographic ploys. These include stop-motion animatronics and intense low and high camera viewpoints. Additionally, there are speedy and often aggressive editing methodologies. A man with a Camera is not just a film; it is also a declaration, a policy, documented in celluloid. There are things and pictures in Vertov’s movies that are intended to be read. Nevertheless, marking those instants and interpreting those images might not be straightforward. Salt of the Earth was a part of surfacing females’ series. On its production, the film was in 16mm with faulty scenes and inaudible tracks. The film has forecasts in the montage series with the editing juxtaposing Ramon’s being crushed with Esperanza’s child delivery. In the last sequence, the camera and screenplay highlight the coalescence of the varying quandaries, forming a unite d class identity. Moreover, firearms in the movie serve a factual purpose and become symbols for a rudimentary machismo, and also for the influence of the ruling category. In the concluding frames, the camera visually generates the image of harmony recapitulated by Ramon’s spoken statement. The film utilizes linear features and also fails to utilize the camera and editing functions innovatively (Salt of the Earth, p.1). In the Ideology of Modernism, Lukacs dashes his critique to the bourgeois notion of modernism which has alienated man and community and offered emphasis to the structure rather than content. He utilizes three conceptions in this essay. They include Russian formalism, existentialism as well as scholars who introduce stream of consciousness method. These three presumptions have separated art from the community; they present a negative elucidation of art and the humankind. This Russian

In the two(2) novels, analyze how the science in Science Fiction is Essay

In the two(2) novels, analyze how the science in Science Fiction is essential to making Science Fiction a literature of cognitive estrangement - Essay Example Individuals will then believe, that confidence, to be a sense of power. So, we can see the link between science, psychology and power, with science being the initiator. But, some times the acquired power could be a false sense of power as well. This paper will discuss this link and the role of science through the characters, Case and Armitage in Neuromancer written by William Gibson and through Androids in Do Androids Dream of Electric Sheep?, written by Philip K. Dick, and thereby analyze how the science in Science Fiction is essential to making Science Fiction a literature of cognitive estrangement. The environment in Neuromancer is full of science in the form of cyberspace. In that environment, the central character of Case, a computer hacker was recruited by a shadowy character, Armitage along with Molly to complete a series of missions. And in the course of the story, that mission control gets transferred to an Artificial Intelligence entity, named Wintermute, which uses Case’s services and science to integrate with another AI entity, Neuromancer. The mind of Case is an addicted one. Apart from the drug addict ness, which he suffered due to his low life; Case’s mind was also addicted to an entirely different entity, the entity of Cyberspace. That is, Case’s desire to connect to the cyberspace was thwarted by the injections of neurotoxins administrated by his corporate employers for his act of stealing. So, this injection of neurotoxins destabilized his nervous system and made him ‘handicapped’ to jack in the cyberspace. This of inability of Case to connect to the cyberspace created a sort of craving for the cyberspace and which only transformed into addiction. â€Å"For Case, whod lived for the bodiless exultation of cyberspace, it was the Fall. (Gibson p.12)†. And, this addicted mind got a new thought process when Mr. Armitage, wanted to utilize Case’s hacking abilities. So, using the computer technology and

Patient Diagnosed With Cancer Essay Example | Topics and Well Written Essays - 1750 words

Patient Diagnosed With Cancer - Essay Example Tabitha is a 1-year-old patient who was diagnosed with cancer two years ago and has received two courses of chemotherapy. She understands and respects every decision with regards to treatment and is due to have another round of chemotherapy. The treatment can make a 30% chance of survival or approximately two years. Without this, Tabitha will die within three months. Tabitha has a good relationship with the clinical team. She also has a supportive family and friends all throughout the treatment. She attends the local school when she is not sick and lives with her brothers and parents. The ethical dilemma started when Tabitha refused consent chemotherapy because of being fed up in the hospital to receive unpleasant treatments. According to the ANMC National Competency Standards for the Registered Nurse Section 2.3 (2008), a registered nurse practices in a way that acknowledge the dignity, culture, values, beliefs, and rights of individual groups, including the consideration of individ ual/group preferences when providing care (p. 3). Respecting Tabitha’s refusal to treatment is in line with the practice of professional and ethical nursing framework; however, doing so might sacrifice the safety of Tabitha and death within three months. The legal issue in this case study centered on Tabitha’s right to make a decision. Although she is mature enough to understand the treatment and her parents are supportive of the decision to refuse chemotherapy, she is still a 16-year-old patient.

International Trade Operations in Egypt Essay Example | Topics and Well Written Essays - 1000 words

International Trade Operations in Egypt - Essay Example The paper tells that Egypt happens to be the most populated Arab nation. It also happens to be the second most populated African Nation. Most of the population of Egypt is concentrated in the big cities like Alexandria and Cairo and in and around the Delta of the Nile Valley. The population in the rural areas in Egypt is on the decline because a large number of Egyptian populations are migrating to the urban hubs to assess a better life style and to benefit from the economic development taking place in these urban hubs. Egypt could be classified to be a well educated nation with its literacy rate being 71.4 percent. In Egypt education is free right up to the university level and it is compulsory from age 6 through 15. The long standing Egyptian President, Hosni Mubarak had to resign following large scale political protests in the nation, predominantly led by the young people. In the year 2004, the Egyptian government initiated large scale economic reforms aimed at privatizing the los s making public sector units and rationalizing the tariffs and taxes. Egypt experienced a commendable economic growth, resting at 7 percent till the year 2008. However, with the onset of the global economic crisis, the economic growth went below the earlier 7 percent mark. Considering the recent, widespread political protests in Egypt, the rate of economic growth could be expected to remain low for the time. However, it could reasonably be assumed that Egypt is gradually moving towards a democratic, parliamentary form of government. With the initiation of the political reforms, the Egyptian economy could favorably be expected to align further with the Global economic trends and Practices. Slide II Egypt is not only the home to a fast growing population, but, the positive thing is that a majority of the Egyptian population comprises of young people and the aged constitute a miniscule of the Egyptian population. It is a fact corroborated by commonsense that young people are usually mo re open to new ideas, ways of doing things, products and services. Besides, young people are usually more informed about the global trends be they political, economic or culinary. Also considering the large size of the population that mainly comprises of young people, Egypt will have to import more food products to feed it. Going by the fact that most of the Egyptian farming and diary is concentrated in the Nile Valley, which comprises of a meager arable land, not capable of producing enough food to feed the large Egyptian population, it could well be expected that in the times to come, Egypt will have to rely on the outside sources to feed its fast growing population. Also, going by the concentration of young people in the Egyptian population, in the times to come it could safely be assumed that this relatively young population will exhibit a marked preference for foreign foods and culinary delights. In that context, it is a propitious time for the Content Cow Diary to export its p roducts to Egypt. If it forays into the Egyptian markets right now, it could pragmatically expect to consolidate its position in the Egyptian markets, in the times to come. Slide III International trade to a large extent is determined by the free interplay of demand and supply and the economies of scale that varied nations command in the context of specific products. If one looks at the GDP of Egypt, one could easily see that the agriculture sector contributes a meager 14.4 percent to the national GDP (CIA The World FactBook, 2012). In contrast, the other pillars of the Egyptian economy that are industry and services sector contribute 39.5 percent and 45.8 percent respectively to the national GDP (CIA The World FactBook, 2012). Thus, it will be quiet realistic to assume that the agriculture sector in Egypt is not well developed and modernized and could not be expected to churn out enough to be able to feed

Chicano studies - Essay Example This is because circumstances forced them to isolate themselves from the mainstream Americans especially after the end of the Mexican American war. The geographical distance made it difficult for them to interact with the Native Americans and as a result most of them maintained their culture unpolluted. A good number of them adopted some aspects of the culture of the Americans and consequently brought confusion on the identity question. The culture of the Hispanics was mixed and up to today most of them portray aspects of the two cultures hence most of them lack a clear perception of their identity. The Hispanics have for long time been treated as second-class citizens as evidenced in the oppression and discrimination they have experienced especially economically. This discrimination has led to existence of a deep division among the communities with foreign origin and the natives. Consequently, this has fueled the rise of land activists groups among others in a bid to fight for their rights. Colonization is creating a colony where one group of people moves to a foreign land and dominates the local residents whereas decolonization is the withdrawal of the foreign dominance where the colony attains independence. The colonization of the Spanish Northern Frontier involves three major events where the New Mexico is first invaded and later a new conquest, which ultimately led to attainment of independence. The colonization of the Pueblo Indians involved a lot of violence, as villages were burnt, sacred places destroyed, murder of people especially the leaders and indoctrination of children. Colonization led to a lot of injustice on the colonies and it resulted to colonization of the mind where the Pueblo Indians could not make free decisions uninfluenced by the colonizers. The colonization of mind is the worst level of any form of colonization as it denies one the natural gift of free will that

Difference between theology and religious studies Essay

Difference between theology and religious studies - Essay Example On the conventional account, theology differs from other forms of reflection, including religious studies, for one or both of two reasons: (1) because it has to appeal to special criteria of truth for some if not all of its assertions; and (2) because the theologian has to be a believer who already holds these assertions to be true. (Ogden) People of the Christian faith cannot accept principles of other religions, unless they conform to Christianity. An example would be a Christian believes Jesus Christ is the Savior and is equal to God the Creator. This means a Christian would not adopt views contrary to this, such the Islamic or Judeo belief in one God. Theology only reaffirms the belief in Jesus Christ. different from religious studies, as well as from other forms of reflection, even it it were in full compliance with the same standards of reflection, since the sufficient ground of its difference is the question that constitutes it a distinct field of reflection—namely, the reflective question as to the meaning and truth of the Christian religion, or witness of faith. (Ogden) â€Å"Religious Studies" is often used as a general heading, covering a multiplicity of possibly conflicting methodological approaches to religion. Some of them still tend to be regarded as alternatives to "Theology". (Leirvick) Many of the non-Christian religions have religious instruction in their Temples, Mosques, and other institutions instead of teaching their religion in colleges. College courses for these religions are for knowledge, not the believer. Theology is taught at colleges and universities built around the theological study. Religious studies are for knowledge, whereas theology is for the believer in Christianity. Theology is the study of the Christian faith, whereas religious study deal with every other religion. Theology is taught in mainstream colleges and universities. Religious studies are also taught in mainstream colleges and universities,

Importance of Wearing a Condom Essay Example for Free

Importance of Wearing a Condom Essay The aim of using a condom is to ensure that there is no contact between the sexual fluids that come from a man’s penis and the sexual fluids, blood or ‘lining’ inside his partner’s body (vagina or anus). Using a condom prevents transmission of sexually transmitted diseases/illnesses (STIs) – from man to woman and from woman to man or from man to man. Using a condom prevents unwanted pregnancy and allows couples to plan when they have children. If used correctly, a condom stops HIV passing from an infected person (who may not know he or she is infected) to an uninfected person. Condoms can also stop someone with HIV being re-infected with the virus. Without a condom, STIs and HIV can pass from one body to another – man or woman. During penetrative intercourse without a condom (in other words, where sexual fluids mix as a result of contact between genitals), a man’s body can pick up HIV from an infected partner – or a woman’s body can pick up HIV from an infected partner. Condom use is always crucial because HIV and some other STIs have no symptoms – they are invisible. Another advantage is that condoms delay ejaculation, increasing the length of penetrative sexual intimacy and pleasure. Many people have already contracted HIV. Using condoms correctly can protect them from re-infection and from increasing their viral load. Condoms also keep their partners or spouses safe from infection during intercourse. Condoms, used properly and with confidence (every time): * Can prevent (re-)infection from many STIs, including HIV. * Can protect fertility (some STIs, with few evident symptoms, can cause infertility in women and men). * Can enable you to plan pregnancy – or prevent it. * Can help you avoid anxiety and risk and let you choose health, safe pleasure and to care for your body (whatever sex you are) and for your partner’s body (whatever sex they are).

The Aircraft De Icing Engineering Essay

The Aircraft De Icing Engineering Essay This report explains the results of research into how de-icing operations at Minnesota Saint Paul could be improved. The findings were that this airport should use a combination of infrared heating and antifreeze spraying in order to deice aircraft in a fast, safe, cost effective and environmentally friendly way. The de-icing process is called the drive through method and this report has backed up its investigation through detailed calculations and the use of a decision matrix to compare the benefits of the drive through method against using others. Although there are some problems such as its relatively long payback time of 2.5 years, plus risk the airport may have to pay licence fees due to patents on the technology, the benefits of the drive through method outweigh these drawbacks. One reason for this is that after the payback period the airport will make an annual saving of approximately $7,080,000 INTRODUCTION Rationale for the research The process of removing ice, frost or snow from the surface of an aircraft is known as aircraft de-icing. This is an essential procedure because if these substances accumulate on an airplane they will amplify the drag force that the plane experiences. This will reduce the ability of its wings to produce enough lift force to allow it to take-off or manoeuvre whilst in flight. Also, damage could be caused if a large piece of ice dislodges from the plane and hits sensitive components like its engine. This could lead to passengers losing their lives in a crash and others losing their properties. The Federal Aviation Administration, FAA, regulate all major civil aviation operations in America. One of their rules is that aircraft must be free of ice before takeoff and during flight. Background This report uses Minneapolis Saint Paul (MSP) airport, Minnesota, as its primary case study. This is because aircraft at this airport frequently needs to undergo deciding as a result of the cold climate before, during and after winter in that region. MSP airport spans 3,400 acres, has five runways, five de-icing pads and served more than 32 million travellers in 2009 making it 15th in the United States and  30th in the world in terms of number of passengers served annually. (MSP Airport, 2010) De-icing is currently carried out at MSP airport by operators who spray an ethylene-glycol based aircraft de-icing fluid onto planes. Storm water drains to collect the waste fluid, before it is transported by a truck to a recycling facility to be treated. It needs treatment because its high Biochemical Oxygen Demand (BOD) makes it harmful to the environment. Research Aims and Objectives This investigation aims to find a method and chemical to use for de-icing planes which is more environmentally friendly, cheaper and faster than that which is currently used in MSP airport. It should be a total solution technology which eliminates/reduces all the problems that the current de-icing method causes without producing detrimental side effects. These aims will be achieved by completing the following objectives: Identify a substitute de-icing fluid which has the same/better de-icing functionality but costs less and is safer than the one currently used in MSP airport. Find a better way to recycle the waste de-icing fluid Ensure that the new substitute chemical allow de-icing fluid to be recycled Find another way to remove snow from aircraft GENERIC DESIGN PROCESS Organisations often use a generic design process as they turn a product idea into a manufactured item. Using a systematic, well organised designed process helps to reduce the research and development time that a novel product experiences. The design team for this project used a generic design process and the actions that they took at each stage are detailed below: Product Planning First the team used product planning to help make that reliable and valid research was carried out straight away. This started this by withholding a discussion in which they clarified the aim and objectives of the project. Then they identified their strengths and weaknesses in relation to these objectives to help them choose which duties they were responsible for. Finally they agreed upon timescales in which to achieve each objective. Identification of Customer Needs Customers needs guided the teams product innovations that were found. The team held interviews with a representative from each major stakeholder group in the airline industry, such as the airline manager and spray operator, to allow them to voice their needs. This made it easier for the team to set product specifications and design a product that they would approve. Establishment of Product Specifications The customer needs were ranked in order of their importance. The rank of each need was proportional to a weighting, w, which was later used in a decision matrix. This information was used to generate product specifications which were further defined using metrics. Generation of product ideas A brainstorm was held to generate product ideas. This was useful because it encouraged the team to build ideas on top of one another. From this they saw similarities between ideas and linked some of them to define a total solution technology. Selection of product ideas A decision matrix was used to quantitatively compare the importance of each customer need in relation to the product ideas. The product with the highest score was selected for testing. Testing The total solution technology was further evaluated in terms of its performance and economic viability. Because it was very beneficial its specifications were was sent to manufactures so that they could build a prototype. Figure 1 An illustration of the generic design process Figure 1 illustrates the product design methodology which begins with product planning and ends with testing and manufacture. The dotted lines show that if one stage of the design process did not give advantageous results the team would go one or multiple stages back in order to refine their previous intentions. Then they would advance through each stage of the process again until they reached the final testing and manufacturing stage. This procedure of assessing and re-assessing product developments ensured that poor designs were eliminated or improved before they reached the testing and manufactures stage. NEEDS Various customers have an interest in aircraft de-icing operations; these individuals are referred to as stakeholders. The success of this venture will depend on how well it meets the needs of these individuals. Hence, the team evaluated each stakeholders need using an interview and ranked it according to its importance. Information Gathering The stakeholders were identified on the basis on who will pay for, sell, use and operate the de-icing technology, these included airline pilots and passengers etc. They were interviewed and their responses are summarised below. Spray operator Q1: How do you deice a plane? A container on a truck is filled with de-icing fluid which is mixed with water to a 50% concentration by volume. I sit in an enclosed cabin and heat the fluid onboard the truck to 70oC before I spray it onto the plane until all the ice melts. Airport manager Q2: How important is the BOD of a de-icing fluid? Very important, we pay the treatment works about $0.35 per US gallon and the price goes up if the BOD increases. Our airport is fined if the BOD5 discharged to the environment exceeds 900 tonnes per year. Q3: How long would you expect to wait for a return on your investment? 1.5-2 years Q4: How much does ethylene glycol cost? The average is $5-7 per gallon. Q5: What precautions were taken since your last incident? We thought of retraining staff, but now operations are run by an outsourced business. De-icing pads and a drainage system were installed. Aircraft manager Q6: What do you think of integrating a heating system onto aircraft? Not ideal for commercial planes because its expensive Air traffic controller Q7: How severe is the disruption caused by aircraft de-icing? During the peak of the winter season there are regular delays. Aircraft must be de-iced again if they exceed a holdover time of 5 minutes. Ranking of needs and sanity check The team identified the most important stakeholder needs and ranked them as listed below. Each need was given a weighting, w, according to its rank as part of a sanity check. Table 1 The rank of each stakeholder need and its weighting Need Weight-ing, w Reasons 1) Safety 4 Safety was the top concern of every stakeholder. Aircraft at MSP airport can only carry passengers if they obey safety regulations set by the FAA. 2) Lifetime Cost 3 Some stakeholders disagreed on financial issues regarding how much cash should be spent on certain items. e.g most spray operators would like luxury de-icing cabins whereas airport managers would rather invest the money. However, all stakeholders agreed that no de-icer with a high lifetime cost would be acceptable. 3) Speed 2 Slow de-icing can cause profit losses due to delayed flights. 4) Environmental impact 1 Although the airport will be fined for causing excessive pollution these costs are normally absorbed by customers. ESTABLISHMENT OF PRODUCT SPECIFICATIONS Most of the needs highlighted by stakeholders were expressed in a qualitative manner. They needed to be converted into specifications in order to avoid trivial yet expensive improvements being made to MSP airport. To do this the worst case de-icing conditions that could potentially take place at MSP airport were defined and as part of sanity check. Next metrics were used establish specifications for product and process design methods that could cope with the worst case de-icing scenarios at the airport. Specification 1 Annual length of operation The dates in which the planes will need to be de-iced ranges from November to early April because on these dates the temperature in Minneapolis Saint Paul is below freezing. Therefore, any new de-icing method must be able to operate through this period of 5 months and 1 week (157 days) every year. (Figure 2) Figure 2- The average lowest temperature in MSP every year from 1971-2000 Specifications 2 The case study aircraft and its ice coverage The mass of ice on a plane was calculated using a worst case scenario, which was that one of the biggest commercial passenger planes; the Boeing-747 (BBC, 2007) needed to be de-iced. It was assumed that the top area of both its wings was covered by a 1cm thick layer of ice. Wing area (Boeing-747) = 541.2 m2 (Airliners, 2010) Ice Thickness = 0.01m Ice Coverage 100%  Ã…“ Volume of ice on wings, Volice = 5.412 m3 (App. 1, Eqn 1) Density of ice, à Ã‚ ice = 917kg/m3 (Kotz, 2009)  Ã…“ Mass of ice, = 4962.8 kg (App. 1, Eqn 2) Specifications 3- Heating Duty Latent heat of fusion of ice= 333 kJ/Kg (Bird, 2003)  Ã…“ Minimum heating duty = 1652.6 MJ (App 1, Eqn 3) Specifications 4 The substitute de-icing fluid The atmospheric temperature in MSP airport during the de-icing season is 20oF (-29oC) therefore the substitute ADF freezing point must be less than 20oC in order to maintain its functionality. Additionally it must provide a freezing point depression of more than 20oC as a result of this ambient temperature. All the stakeholders agreed that product safety is of upmost importance, so the substitute ADF should be less toxic than ethylene-glycol. Additionally they agree that the annual raw material costs of the new dicing method should be less than that of the current method. Two ways to do this are to use less dicing fluid per plane in the first instance; this should be less than the 408 gallons per aircraft required by the current de-icing method (App. 1, Eqn. 9), or to recycle the de-icing fluid. GENERATION AND SCREENING OF IDEAS The team worked individually and brainstormed together to help maximise the number of good ideas that were generated. Whilst doing so they reflected upon the product specifications to and stakeholder needs to help screen ideas. De-icing Ideas De-icing boots Rubber boots are attached to the front edges of wings on the plane. The aircraft inflates these boots with air to cause ice that remove ice that has accumulated on them. An unacceptable risk of using this method in MSP is that the system must be activated as soon as a before an large ice layer can form and hit other parts of the plane when it dislodges. Bleed air- In this method hot air from the aircraft engines is blasted on to the ice to melt it. Although this could melt ice very quickly the airport manager at MSP airports commented that integrating heating systems on to aircraft is not ideal for commercial planes because its expensive. Mechanical Scraping/Blowing Employees use brushes, or cloths to physically push ice off the aircraft. This method would be very easy to put into practice at MSP because the equipment the required is very cheap. But it is more likely that damage will be done to airplanes as the employees scrape ice so the resulting aircraft maintenance cost is could be very high. A propylene glycol based de-icing fluid Propylene glycol is a popular de-icing fluid and is regarded as non-toxic, hence it was chosen for further investigation. Decision Matrix The interviews that were conducted with the stakeholders highlighted that some customer needs are more important than others. Although the importance of some specific needs differed in each stakeholder group four needs were consistently rated as essential. These criteria were analysed in a decision matrix with weighing marks taken from Table 1 Table 2- Decision Matrix which focuses on the alternative deinking methods ALTERNATIVES Ethylene Glycol (Benchmark)   Propylene Glycol Infrared + Propylene-glycol Criteria Weighting w Rating Score Rating Score Rating Score Safety   5 2 10 4 20 7 35 Lifetime Cost   4 5 20 5 20 6 24 Speed   3   5 15   4 16 6 18 Environmental impact   2   1 2   5 10 6 14 Total   14   13 47   18 66   25 91 According to this decision matrix the best de-icing solution should be based on a combination of infrared and propylene glycol de-icers is the best as this alternative has the highest sore. The second best method would be to use an ADF which is based on propylene glycol rather than ethylene glycol. SELECTION OF IDEAS A comparison of ethylene-glycol and propylene glycol based de-icing fluids The most freezing point depressants in aircraft de-icing fluids in the US are ethylene glycol (EG) and propylene glycol (PG). Because PG and EG have a similar lifetime cost, in this chapter the chemicals will be compared at a 50% concentration by volume in terms of their safety, de-icing speed and environmental impact because these are three of the most important needs the stakeholders. Safety Ethylene glycol has a relatively high toxicity when compared to Propylene-Glycol. It has been classed by the US congress as a hazardous air pollutant (HAP), if 2268 kg or more escapes into the environment within 24 hours users are obligated to report the event under the Comprehensive Environmental Response Compensation and Liability Act (CERCL). However propylene glycol is not classified as a HAP, and users are not required to inform CERCL if it is released. Both chemicals are said to be non-lethal if humans if they are breathed in with air or adsorbed through skin. However, unlike PG, EG is toxic to humans and mammals if it is ingested directly. Even though PG it is regarded as non-toxic it is still a health hazard because it uses oxygen as it biodegrades which could cause some organisms to suffocate. De-icing Speed The freezing point of Propylene-glycol is -34oC which is slightly higher than ethylene-glycol which freezes at -37oC. This is one of the reasons why MSP airport still uses EG. Another is that a lower volume of antifreeze is required for EG to achieve the same freezing point depression as PG. MSP airport suffers severe weather extremes so it needs to use an ADF which is reliable, especially in extremely cold weather as this is generally when it takes longer to deice aircraft Propylene-glycols boiling point is 106oC whereas ethylene glycol has a boiling point of 102.2oC for ethylene glycol. In this case Propylene-glycol is the better choice because it can transfer heat to ice at a higher temperature than ethylene glycol. Discussion There are some drawbacks with regard to using ethylene glycol as a de-icing fluid, especially concerning its environmental impact. But, overall EG and PG have a similar de-icing performance level. The Rate of Melting due to Heat Conduction Alone The ADF is heated to 70oC before it is sprayed onto the plane, this heat alone will cause the ice to melt through heat conduction. The rate of this heating was calculated using equation 1a, 1a) Where Q= is the heat flow rate in the X-direction in kJ/s, A is the area normal to the direction of heat flow in m2, dT/dx is the temperature gradient and K is the thermal conductivity of ice The thermal conductivity of ice at -20oC is 2.39 W/mK, the area normal to the direction of heat flow is equal to the wing area of the Boeing 747 =541.2m2, the temperature change that occurs is (70oC- -20oc)=90oC and the thickness of the ice x is 0.01m. Hence the rate of heat transfer by the temperature of the de-icing fluid alone is 2a) The sensible heat is kJ (App. 1, Eqn 12) The latent heat of fusion is 1652612.4 kJ, (App.1, Eqn 3) Summing the above gives the amount of het required to melt the ice on a Boeing 747 from a starting temperature of -20oC which is Hence minimum time that it would take to melt the ice on the plane by heat conduction alone is This is a very fast time, especially as according to the project brief, de-icing at MSP airport normally takes 10 minutes per plane. One reason reason for this difference is due to the fact that the ADF fluid is not always in full contact with ice, only its bottom surface is. Additionally these calculations assume that heat transfer occurs over the whole of each wing evenly, which is not the case in real life because de-icing fluid is sprayed onto the wing in different locations systematically. A final cause of this difference could be due to the fact that snow has a lower heat conductivity, k, than ice and so any snow on a plane would lower the rate of heat transfer from the ADF. TOTAL SOLUTION TECHNOLOGY Drive-Through De-icing Figure 3 An illustration of the drive through de-icing technology The final design concept was to conduct de-icing operations as a drive through system. First the aircraft enters the Infrared hangar where and warm air blows snow of its wings whilst they are heated by infrared radiation for a typical duration of 5-10 minutes. Ice on the plane melts onto an inclined slope and the wastewater is channelled into the waste collection zone. Water is channelled through existing storm water pipes into infrastructure to the located under the floor of the spraying and waste collection area. The wastewater is pumped out and transferred by a truck into the airports detention ponds. When the wastewater has been removed compression plugs are removed and the plane moves into the spraying area. Here it is sprayed with propylene glycol for up to 5 minutes to help prevent any ice forming on it before takeoff. The propylene glycol drains into a separate area of the collection chamber and is pumped to a detention pond until it is due to be recycled. Finally the compression plus are reinstalled so the system is ready to deice another plane. Recycling Solution Minneapolis currently uses three Glycol Recovery Vehicles to collect wastewater. Using the IR facility eliminates the need to deice aircraft using glycol by around 90%, so no more of these vehicles will need to be bought if the new technology is adopted. Also the airport has saved capital costs by using their existing storm water drains to collect both glycol and storm water. These storm drains can and should continue to be used if MSP airport adopts the Drive-Through De-icing system to save cash and time during the installation of the new system. According to (Big book) Careful management of the retention systems enables the airport to collect enough wastewater with high glycol concentrations to make glycol recycling/recovery economically viable. The majority of glycol which is recycled is sold to manufacturers who use it in other glycol-based products. ANALYSIS OF ECONOMIC VIABLITY Rate of return on investment (ROI) 3a) Payback Time 3b) =2.5 years Unfortunately the payback time on the drive through de-icing method is not fast enough to satisfy the Airport Managers at MSP who expect a payback time of 1.5-2 years. A higher rate of return on investment would reduce the payback time so it would be wise to look into additional ways to reduce the cost of de-icing using this technology, and ways to improve its efficiency. Patent issues Because this total solution technology uses de-icing methods which have been used in industry previously, but it combines them in a unique way it is difficult to assess whether or not it can be patented. Moreover, it is expected that it would take a long time to patent the product even if it were possible because of its complexity and use of old de-icing ideas. The author has recommended that MSP airport consults a lawyer regarding these matters if they do not need to use the de-icing solution immediately. If MSP airport do need to use the technology immediately they might have to pay license fees to one or more patent owners. CONCLUSION The findings from this investigation have shown that the solution technology that MSP airport should use to improve its aircraft de-icing solution involves using infrared heating and a propylene glycol as a substitute chemical for ethylene-glycol. The process is called the drive through method and the major advantages of this hybrid solution are that it meets the needs of its stakeholders by being safe, having a low lifetime cost, fast aircraft de-icing rate and low environmental impact. Evidence of this has been provided through a decision matrix and several mathematical evaluations. Unfortunately this solution has a payback time of 2.5 years, so research should be carried out to reveal how to make the annual rate of return on the investment higher. Finally, this hybrid system uses patented technology so MSP airport might have to pay licence fees for a number of years if it used the drive through method. However, after the payback period the annual saving of $70,844,300 per year outweighs any of these drawbacks. Further Recommendations Find ways to cut the operating cost of the Drive-Through De-icing system as this will lift the annual rate of return that this technology provides. If the rate of return is high enough the payback time will drop below 2 years and the airport managers in MSP will have this need fulfilled. Use hot air to blow snow off the aircraft in the IR hangar. This will help to melt the snow and ice too, however the cost of warmin+ 3.0g air may offset the benefit of a faster de-icing time. Nb, as shown by the weightings, w, in Table 1, the lifetime cost of the technology is more important that the de-icing speed that it provides.

The metrics are based upon a 50% by volume solution of each chemical. Volume of Ethylene Glycol Required The freezing point depression of an ideal solution is given by the formula (5) Where à ¢Ã‹â€ Ã¢â‚¬  Tf represents the freezing point depression, m, is the solute concentration and Kf represents the freezing point depression constant of water which is 1.86 °K ·kg/mol (Kilter P., Mosher M. and Scott A. Andrew scott, 2008) The desired freezing point depression, à ¢Ã‹â€ Ã¢â‚¬  Tf is 20oC because winter temperatures in MSP fall to that temperature, according to the project brief. (6) The number of moles of glycol required to achieve the freezing point depression: (7) The chemical formula of ethylene-glycol is CH2OHCH2OH Mr Carbon = 12, Oxygen=16, Hydrogen=1  Ã…“Mr ethylene glycol = 2*16+2*12 + 1*6= 62 g/mol Hence the mass of ethylene-glycol required per plane is: (8) The density of UCAR ADF at 20oC is 8.9 lb/gal (US) (1.07 kg/L) (SAE AMS 1424 Ethylene Glycol-Based Type I Fluids page 8) Hence the volume of ethylene-glycol required is at least 408 US gallons (9) Because the de-icing fluid used in MSP airport is 50% ethylene-glycol and about 50% water, de-icing a single plane would need double the amount of ADF which works out at 6,184 litres. The cost of ethylene glycol per aircraft In general the chemical components in de-icing fluids, such as water, have a total cost which is substantially less than that of ethylene-glycol. Hence the cost of these components in de-icing fluid solutions as deemed insignificant and ignored. According to the airport manager that was interviewed the minimum cost of a gallon of ethylene glycol is $5 per US gallon (10) In MSP airport there is an average of 293 takeoffs per day from 5 de-icing pads (MSP Airport, 2010) Assuming that during the de-icing season in MSP lasts 157 days and every plane needs to be de-iced the annual cost of ADF is approximately (11) Sensible heat required According to the project brief winter temperatures in Minneapolis Saint Paul fall to-20oC. Ice must be brought to its melting point of 0oC before it can undergo a phase change from solid to liquid. Where Cp is the specific heat capacity of ice at -20oC which is 2 kJ/kg/K, (Tsokos KA, 2010), m is the mass of ice and à ¢Ã‹â€ Ã¢â‚¬  T is the temperature difference (12) According to Wingsmagazine (2010) Ian Sharkey, the director of de-icing services, with Radiant Aviation Services stated that during an ice storm on March 15-16, 2007 his team had an average aircraft block time (aircraft brakes on to brakes off) of less than 43 minutes for large aircraft hence it was assumed that the Boeing 747 could be de-iced in this timeframe as well. This information was used to estimate the power that the IR deice would need to bring the ice on an aircraft from -15oC to 0oC in 43 minutes, (13) Latent heat required Next was calculated which is the power needed to melt the ice on the aircraft at 0oC in 47 minutes. (14) Hence the total power needed to melt ice on the aircraft in 43 minutes by using infrared deink technology, QIR is (15) To make the value of QIR more realistic some assumptions concerning the amount of energy loss, between the heat source and the wing were added. From this the extra power that the laser will need to give out in order to overcome the inferred energy lost as between the source and its destination (transport efficiency) and the energy lost due to reflection by the ice on the surface of the wing (absorption efficiency) was calculated. Laser device efficiency, ÃŽÂ ·laser=0.33, Transport efficiency, ÃŽÂ ·transport = 0.75 Absorption efficiency, ÃŽÂ ·absorbtion =0.75 The laser device, transport and absorption efficiencies reduce the amount of energy that heats the ice.

The Course of The Great Depression Essay -- Great Depression American

The Course of The Great Depression The October 1987 collapse in stock prices conjured visions of 1929 and the Great Depression. Focus on this period is natural because the 32 percent decline in stock values between the market closes of October 13 and 19, 1987, was of the magnitude of--indeed, it actually exceeded--the October 1929 debacle. Focus on this period is also appropriate because, despite all that has been learned since to help assure economic stability, we cannot be completely confident that history will not repeat itself. Consequently, this first section reviews events of the Depression era. The stock market Crash of October 1929 is frequently credited with triggering the Depression. The decline was severe and extended; from their peak in September 1929, stock prices declined by 87 percent to their trough in 1932. The performance of the economy over this period was equally disheartening. Real economic activity declined by about one-third between 1929 and 1933; unemployment climbed to 25 percent of the labor force; prices in the aggregate dropped by more than 25 percent; the money supply contracted by over 30 percent; and close to 10,000 banks suspended operations. Given this performance, it is not surprising that many consider these years the worst economic trauma in the nation's history. Policy makers did not stand idly by as the financial markets and the economy unraveled. There are questions, though, about the appropriateness and magnitude of their responses. Monetary policy, determined and conducted then, as now, by the Federal Reserve, became restrictive early in 1928, as Federal Reserve officials grew increasingly concerned about the rapid pace of credit expansion, some of which was fueling stock market speculation. This policy stance essentially was maintained until the stock market Crash. While there has been much criticism of Federal Reserve policy in the Depression, its initial reaction to the October 1929 drop in stock values appears fully appropriate. Between October 1929 and February 1930, the discount rate was reduced from 6 to 4 percent. The money supply jumped in the immediate aftermath of the Crash, as commercial banks in New York made loans to securities brokers and dealers in volume. Such funding satisfied the heightened liquidity demands of nonfinancial corporations and others that had been financing broker-dealers... ...tivity was under way prior to the market debacle of October 1929. In contrast, the cyclical expansion in business that followed the recession of 1981-1982 remains intact today. Moreover, examination of the Depression years can help us to identify policies that minimize the risk of a slowdown in economic activity and to avoid the major errors of the past. In this regard, the principal recommendations that emerge from our admittedly subjective review of history are: -- maintain our commitment to the stability of the banking system through judicious use of the federal safety net of deposit insurance and the discount window; -- support normal credit extension by banks and, more generally, smoothly functioning financial institutions and markets through stable and credible macroeconomic policies; -- provide adequate growth in the money supply consistent with prevailing economic circumstances worldwide; and -- promote open markets for the international trade of goods and services. Such a list of policy recommendations may seem unremarkable, in part because the lessons of the past already have been taken to heart. Achievement, however, is likely to prove a challenge.
