Preparation of Nylon-6 from petroleum - Essay Example DuPont continued with his research and in 1941 pioneered the first moldable polyamide grade. However, in 1938 a German P. Schlack at IG Farbenindustrie produced another commercially important nylon 6 through caprolactam and its subsequent patenting being done in 1941 (Brown, Foote, and Iverson 2011, p.6). The market for nylon-6 has since then grown and is used for various purposes worldwide. Nylon 6 is the most popular type of nylon in use and accounts for more than 50% of the global market (Brown, Foote, and Iverson 2011, p.9). The nylon falls under the thermoplastic family and has several properties that make it different from other types of polyamide. The properties of nylon 6 include the fact that it is tough, with high tensile strength. This implies that it does not break easily due to the bonding between each molecule resulting from the polymerization process. Secondly, nylon 6 does not wrinkle. It is also highly resistant to abrasive effects, such as alkalis and chemicals. This implies that it does not tear easily when such chemicals get into contact with the material. The product is also capable of absorbing water of up to 2.4%, which in most cases reduces its tensile strength (Brown, Foote, and Iverson 2011, p.9). In addition, nylon 6 is highly elastic and has the capacity of being used as a technical nutrient. Moreover, it is a semicrystalline polyamide. Nexant (2009, p.1) notes that nylon 6 is used extensively particularly in the automotive, industrial, consumer, as well as in electrical and electronic industries. However, its use has grown particularly in the automotive industry. This is attributed to the fact that there has been a trend towards preference of plastic material to metals as weight and cost reduction strategies. In addition, the use of nylon in the automotive industry has been seen as a means of reducing vehicle emissions that pollute that environment. Market outlook shows varying

Roles of Multidisciplinary Teams for Chronic Patients Assignment

Roles of Multidisciplinary Teams for Chronic Patients - Assignment Example In respect to this, it is important that it is known that most of the chronic infections are hereditary while other are dependant on the nature of life for example smoking. They can only be treated since cure is not possible. Chronic diseases cut across the board in what is referred to as A to Z. there are numerous categories of chronic diseases starting from Arthritis, Alzheimer's to zoonoses chronic illness that are passed from animals to human, avian flu is an example (Brighton, 2005). Of recent obesity has also added onto the long list of the chronic diseases. The cost of maintaining life in the presence of the chronic illness is seriously expensive and inmost case if one can not afford the cost then they simply succumb. For example in diabetes, there is need to inject insulin on a daily basis for those with the acute form (Brighton, 2005). Since most of the chronic illness cannot be completely be cured, there is extensive support from the health care providers such that the pati ent are given the orientation on how to manage some errands on their own. Before leaving the hospital the patient are given the basics of their condition and how to manage the conditions in the absence of the doctor (Larsen, Pamala, and Ilene, 2009). Cases of chronic illness can most likely lead to the disillusionment of the patient in taking care of themselves, this is because of the constantly recurring illness condition that requires very close monitoring and any complacency may be lethal to ones life. This make the patient to have the feeling that they are not able to enjoy life and get to be depressed and can developed great sense of trauma. In this case the patients require psychological therapies (Lubkin, Ilene, and Pamala, 1988). The trauma that is experienced by the patients can be horizontally be transferred to the heath care givers and even to the close family members in what is referred to as compassion fatigue or burnout. Compassion fatigue is defined as the cost of pro viding care to the patients as one tends to empathize with them to the extent that they themselves get affected (Ackley, & Ladwig, 2010). In the contemporary society, one of the most worrying chronic infection is the oncology cases, the development of cancerous cases is on the rife and this is attributed to the lifestyle that majority of the peoples have opted for. For this purpose, the prevalence and incidence of the cases of chronic infections will be considered. Prevalence of a disease consider finding the rate at which the disease spreads while in incidence, we do considers a snapshot number of the individuals who are victims as at a specific time (Funk, 2001). Characteristics of chronic diseases Chronic diseases have many factors in common; most of the chronic diseases are brought about by the lifestyle led by the individual. The emergence of these illnesses are solely brought by the nature of the life they opt for, for instance, in the over consumption of alcohol is known to o verwork the pancreases and this impairs the performance of the pancreas and may not be in a position of secreting the necessary hormones that are required for the regulation of some important factors like the control of the sugar level in

Analysing The United States Presidential Election Of 1916 Politics Essay

Analysing The United States Presidential Election Of 1916 Politics Essay An election, to most, is a vote taken to determine who and what party will hold office for the government in question for a set term. Though this is accurate, an election is also a reflection of not only the government and the people to which that government supports, but in fact the entire world at that time. The year of 1916 was one of optimism, opposition, nativism, womens rights, allies, central powers, trenches, progressivism, isolationism and a great deal of nationalism. The Great War had started two years prior and a small amount of other serious conflicts such as Easter Rising, the Arab revolt against the Ottoman Turks and the Mexican Revolution had begun to take place as well. The incumbent to the presidency had appointed his first Jewish Supreme Court Justice, Louis Brandeis, and the US had invaded Cuba for the third time due to the corruption of the Menocal regime. 1916 also presented many achievements in a variety of subjects: the rise of Charlie Chaplin; the first succes sful blood transfusion; the invention of the light switch; the creation of the Boy Scouts; the beginning of Boeing Aviation; approval by more states of womens suffrage; Coca-Colas introduction to the market of the current coke formula; the founding of the San Diego Zoo; the presentation of Albert Einsteins Theory of General Relativity, and the cancellation of the Summer Olympic Games in Berlin, Germany. Although such details may seem insignificant, no time ever lived in should be forgotten or secluded from that of the rest. Primary issues, political parties, nominations, elections and results do well to reflect this great time in history and its impact on the US as a nation but just as well should we remember the world as it was. The most predominant factor affecting the world at that time was WWI, or as it was called back then, The Great War. The war had started two years prior to this election and had caused so much turmoil within Europe that the American people where simply dodging the inevitable. The Great War was merely an arms race of one alliance against the other. The first alliance was called the Triple Entente, also called Allies, which consisted, at that time, of Great Britain, France, Italy, Russia, Ireland, Portugal, Serbia, Romania and Greece. The second alliance was called the Triple alliance, also called Central Powers, and consisted of Germany, Austria-Hungary, Turkey, Bulgaria and the entire Ottoman Empire. The conflicting alliances disturbed the American peoples through ethnicity, trade and moral dilemmas. German-Americans as well as the other Central Power country-related Americans had only begun to experience alienation because of the war, but the effect as well as their ties to home beca me a problem in future government involvement. Also, the Americans were supplying both sides. Ford Motor Company, for instance, was supplying the Germans with automobile parts. This, as well as moral conflicts from hearsay about the war, such as the sinking of the RMS LUSITANIA, had much of the United States in conflict. Still, much of the U.S was absolutely adamant towards its isolationist stance on the war. Unfortunately the Great War was not the only problem present in the world in that year. In fact, such conflicts as the Easter Rising in Ireland and the Mexican Revolution also had an impact on many Americans just as easily. Easter Rising was, at the time, the biggest rebellion effort against the British rule over Ireland that had occurred since the rebellion of 1798. To some, it may seem that it was also the spark of what the IRA would later become as well as over 90 years of bloodshed between the IRA and the British. Though most of the attention of the U.S. was centered on the Great War, the uprising in Ireland was most certainly not a missed subject during this time, and most certainly not ignored by the majority of Irish Americans. The Mexican Revolution, however, had a more direct impact on the American people due to its proximity to the U.S. A revolution by a man named Francisco Madero led to attempts by Pancho Villa to reclaim lands lost to the US years before. Pancho Villa the n invaded New Mexico killing 12 U.S soldiers and instigated retaliation from the United States government as wished. Though an invasion, Pancho Villas efforts, however, were merely used for tricking the US into intervening in the revolution by way of invasion themselves as a way of insuring that Villas preferred candidate would emerge victorious. Even more than our involvement, were two questions; how to protect the economic interests we had in Mexico during Tafts administration, and, even more largely, how was this an act of neutrality. Much of the US was uncertain, by this point, of Wilsons capability of dealing with foreign affairs, which had a significant effect on the election as well. The year of 1916 was also an election year. The two primary parties were the Republicans and the Democrats. Minor parties, consisted of the Prohibitionists, Socialists, Socialist Labor Party and the Progressives. The Republicans of this time were seeking more protection on individual rights, restriction in foreign affairs involvement, increases in industry, protection of free enterprise, good education and the right of states to determine womens suffrage. The Democrats, however, were endorsing Wilsons former achievements as the incumbent; military preparedness, a world association of nations to maintain peace after the war in Europe had ended, Pan-American unity, a ban on child labor, womens suffrage, and prison reform. Third parties, for the most part, remained more exclusive on which subjects they found most interesting. The Prohibitionists still kept their focus on the banning of alcohol; its main goal being temperance. The Progressives as well as the Socialists remained determine d on excessive government change and inspiration for radical movements to support the people. Lastly, the Socialist Labor party had kept its views most evidently towards labor modifications. Most parties were in agreement on who would represent what. The Democrats without opposition renominated Wilson and invited Thomas R. Marshall to be his running mate at the Democratic National Convention in St. Louis, Missouri from June 14th to June 16th. The Prohibitionist party held their convention in St. Paul, Minnesota from June 19th to June 21st and nominated James Franklin Hanly as president and Ira Landrith as his running mate. The Socialist Labor Party nominated Arthur Reimer as president and Caleb Harrison as his running mate in their convention in New York City, New York on April 29th to May 3rd. The Progressives were the same in accordance to their nomination of former president Theodore Roosevelt, but Roosevelt turned down his nomination, thus removing the party from the race and pulling former progressives in all directions. Roosevelt endorsed the Republican Partys nominated member quickly thereafter. The Republicans had many candidates in question, but the most promine nt was a conservative Senator named Elihu Root from New York, and a liberal Senator named John W. Weeks from Massachusetts. The partys bosses on the other hand saw that a balance between the two would be more substantial for both ends of the party and result in a once again unified party. It was then, that Supreme Court Justice Charles Evans Hughes was brought into the race without previous interest and won on the third ballot, with former vice president Charles W. Fairbanks as his vice presidential nominee. The Socialists, due to Eugene V. Debs decline to the ticket, did not hold a formal convention. A referendum of the partys members nominated Allan L. Benson, an anti-war activist, for president and George Ross Kirkpatrick as his running mate in hopes of a better chance at the presidency. Due to popularity, precedent, and the incumbent himself, the two primary parties that ran against each other were the Democrats and Republicans. President Wilson, running on the Democratic ticket, came into the 1916 contest with a list of domestic accomplishments, but the race was dominated by foreign affairs and the ongoing world war in Europe. The Democratic Party itself was running most of the campaign on the slogan He Kept Us out of War. Ironically enough, Wilson did not like the slogan due to his doubtfulness in his capability to keep the US out of conflicts with such an uncertain future. Hughes, on the other hand, did not have the advantage of being the incumbent and used his efforts to suppress Wilsons attempt to plead neutrality, as well as his views on labor laws that suppressed businesses and profit. On one hand, the Republican party held militarists, who criticized Wilsons weak foreign policies with Mexico and Germany, but also pro-Germans or pacifists, who simply denounce d Wilsons policies for fear they might lead to war. Hughes was not exact on either approach, but was diligent in his attempt to defeat Wilson. Though both Wilson and Hughes had a mostly similar outlook on the war, Hughes efforts seemed to have been skewed mostly by his own party. Theodore Roosevelt, who had split the party in the previous election, was now giving his endorsements to the Republican Party. Even though he was resentful for his lack of nomination in the party, he felt it was best to support them in order to oppose his most hated Wilson. Roosevelt held many speeches in an effort to support Hughes, but ended up leading a pro-war campaign that did nothing less than upset the majority of the US population and its absolute view on isolationism as well as alienating others. Nearing the end of the election, there was a minor issue in California pertaining to Hughes was slight of both Senator Hiram Johnson and the California Labor Unions. In spite of this, however, most of the American public believed that Hughes was most certainly going to win the election anyway. Results in November, as well, made the election one of the closest in history. Hughes took an early lead in the eastern and mid-western states but Wilson persevered and found himself in the lead with the western and southern votes. Wilson took 30 states for 277 electoral votes, while Hughes won 18 states and 254 electoral votes. Although still narrow, Wilson had also won the popular vote, taking 49% of the popular vote to Hughes 46%. The remaining five percent went to the third parties, leaving a 4% split between the Prohibitionists and Socialists. Voter turnout reached a high of 62%, and would not be matched for another 24 years until Franklin Delano Roosevelt ran for a third term in 1940. Also, the 11 states that had already approved womens suffrage played a great role in the election, as all but one state voted for Wilson. If Hughes had carried California and its 13 electoral votes, he would have won the election. This made the incident in California seem to be the cause which may have very well cost him the election. In account of the election, we also see differences and similarities between past and present elections that allow us to compare and contrast our histories. Vice President Thomas Marshall was the first vice president elected to a second term since John C. Calhoun in the election of 1828. Woodrow Wilson was the only person other than James Knox Polk to win a presidential election but not win his home and birth state. His popular vote margin of 3.1% was also the smallest percentage margin in history for a victorious sitting President until the 2004 election, in which George W. Bush produced a margin of 2.4%. Wilson is also the only president in U.S. history to win re-election with fewer electoral votes than in his first election. However, Wilson is not the only President to win re-election with a lower percentage of the electoral vote in his second election than in his first election. The other president was James Madison, who although had a lower percentage, did have a lower electoral vote total. The election in general also has a distinct relevance to the 2004 election. Wilson, like Bush, was the incumbent president running for a second term whose only previous experience in a political office was as his home states governor. Though one ran on a strong war record and the other on keeping out of the war, Wilson and Bush had both run on their previous presidencys involvement in war. Both were keen on their domestic involvement, however Bush wanted less taxes and Wilson wished for a new graduated federal income tax. Though different, there is most evidently a distinct connection between this election and others that has and will remain most important to our nations history.

My Desire to Teach Literature :: Teaching Education Essays

My Desire to Teach Literature A couple of months ago, out of curiosity, I engaged in a test offered by the MENSA association. Along with the I.Q. figure, I received there was also some two word description attempting to label my intellectual prowess. As I recall one of the words was â€Å"intuitive†, or some variation thereof. People with a propensity to intuitiveness generally have some sense of this. Call it intuition. As a learner I would have to say that I fall into the visual category. For an instructor to describe a mathematical formula, for example, it just does not have the impact as to actually see the process worked out on a blackboard. The same applies to a tangible object. I am able to fully grasp its applications if it was placed before me, as opposed to being merely explained. I do intend to teach in the visual style when, at last, that role is mine. Ultimately my goal is to teach college level literature. Off hand I can think of a few instances where visual tools might be employed in this arena. Suppose I was to assign a class to read Joseph Heller’s â€Å"Catch 22†. Clips from Mike Nichols’ film version would give the class a firmer grasp on the insanity of war. Gustave Dore’s sullen and intense companion paintings to Samuel Taylor Coolidge’s â€Å"The Rime of the Ancient Mariner† would assist in bringing students closer to the mood and drama the poem evokes. And why stop with artistic mediums. Nature herself is the ultimate instructor. After a reading of Emily Bronte’s â€Å"Wuthering Heights† I can see myself marching a class out into a rainfall (weather permitting) and proclaiming â€Å"O.K., guys. You feel those cold drops pounding you? Feel the general wildness of it all? That, my fr iends, is unbridled passion. That is Cathy and Heathcliff in a nutshell.† Regarding the application of learning styles and learning style assessments, quite honestly, I don’t know enough about it yet to make a judgment call. This is new to me and I am still learning. From what I understand of some of these issues, such as integrated learning, this is a practice that should be administered to students at a lower grade level.

Is Flag Burning protected under the First Amendment? :: Persuasive, Exemplification Essay

Is Flag Burning protected under the First Amendment?          There is a proposed amendment to make flag burning illegal. Congress tried to pass the Flag Protection Act of 1989, but the act failed because it is seen as a form of public protection.   There have been other attempts to pass legislation to protect the American flag but all of the attempts have failed so far.    Flag burning is very controversial because people have different definitions of what â€Å"freedom of speech† means and what our flag stands for. This essay explores these definitions from the proponent’s viewpoint for a law protecting the flag and the opponents view point against such a law. The most debated question being asked at this time is:   is flag burning protected under the First Amendment guaranteeing the freedom of speech? It all depends on how a person defines the flag and interprets the First Amendment.    In order to help answer this question let’s being by defining what a flag is. The proponents (veterans, Citizens Flag Alliance, and other organizations of this type) of the amendment for protection of the flag define the flag as a â€Å"cultural artifact with meaning significance, and usage determined by the particular system employing it (Guenter 18).† Some flag historians have recognized the impact of culture on the shifting significance and usage of the national banner, although no one has ventured a full-scale probe of the subject (Guenter 16). The flag in the beginning was a symbol of freedom and enlightenment. The flag design has even changed. The very first flag contained thirteen stars that were in a circle with the red and white stripes. As the nation grew so did the flag, until the flag became what we know of it today.    The proponents also feel that, the flag should never be used for advertising purposes in any manner whatsoever (www.legion.org/flagcode.htm). It should not be embroidered on such articles as cushions or handkerchiefs and the like, printed or otherwise impressed on paper napkin or boxes or anything that is designed for temporary use and discard (www.legion.org/flagcode.htm). Advertising signs should not be fastened to a staff or halyard from which the flag is flown. No part of the flag should ever be used as a costume or athletic uniform (www.legion.org/falgcode.htm).      However, a flag patch may be affixed to the uniform of military personnel, firemen, policemen, and members of patriotic organizations.
