Great Gatsby And American Dream Essays (1273 words) -

Great Gatsby And American Dream The Great Gatsby, a novel by F. Scott Fitzgerald, is about the American Dream, and the downfall of those who attempt to capture its illusionary goals. This dream has varying significances for different people but in The Great Gatsby, for Jay, the dream is that through wealth and power, one can acquire happiness. To get this happiness Jay must reach into the past and relive an old dream and in order to do this he must have wealth and power. Jay Gatsby, the central figure of the story, is a character that longs for the past. Surprisingly he devotes most of his adult life trying to recapture it and, finally, dies in its pursuit. In the past, Jay had a love affair with the beautiful and seemingly innocent Daisy. Knowing he could not marry her because of the difference in their social status, he leaves her to accumulate his wealth to reach her economic and social standards. Once he acquires this wealth, he moves near to Daisy, "Gatsby bought that house so that Daisy would be just across the bay," and throws extravagant parties, hoping by chance she might show up at one of them. He, himself, does not attend his parties but watches them from a distance. When his hopes don't show true he asks around casually if anyone knows her. Soon he meets Nick Caraway, a cousin of Daisy, who agrees to set up a meeting, "He wants to know...if you'll invite Daisy to your house some afternoon and then let him come over." Gatsby's personal dream symbolizes the larger American Dream where all have the opportunity to get what they want. Later, as we see in the Plaza Hotel, Jay still believes that Daisy loves him. He is convinced of this as is shown when he takes the blame for Myrtle's death. "Was Daisy driving?" "Yes...but of course I'll say I was." He also watches and protects Daisy as she returns home. "How long are you going to wait?" "All night if necessary." Jay cannot accept that the past is gone and done with. Jay is sure that he can capture his dream with wealth and influence. He believes that he acted for a good beyond his personal interest and that should guarantee success. Nick attempts to show Jay the flaw of his dream, but Jay innocently replies to Nick's statement that the past cannot be relived by saying, "Can't repeat the past? Why of course you can!". This shows the confidence that Jay has in reviving his relationship with Daisy. For Jay, his American Dream is not material possessions, although it may seem that way. He only comes into riches so that he can fulfill his true dream, Daisy. Gatsby doesn't rest until his dream is finally lived. However, it never comes about and he ends up paying the ultimate price for it. The idea of the American Dream still holds true in today's time, be it wealth, love, or fame. But one thing never changes about the American Dream; everyone desires something in life, and everyone, somehow, strives to get it. A big house, nice cars, 2.5 kids, a dog, a beautiful devoted spouse, power and a ridiculous amount of money. That is the classical American Dream, at least for some. One could say, an outsider perhaps, that Americans strive for the insurmountable goal of perfection, live, die and do unimaginable things for it, then call the product their own personal American Dream. Is having the American Dream possible? What is the American Dream? There is one answer for these two questions: The American Dream is tangible perfection. In reality, even in nature, perfection does not exist. Life is a series of imperfections that can make living really great or very unpleasant. Living the American Dream is living in perfection, and that by definition is not possible, thus deflating our precious American Dream. F. Scott Fitzgerald proves this fact in The Great Gatsby, through his scintillating characters and unique style. Characters in books often mirror the author's feelings towards the world around them. In The Great Gatsby, Fitzgerald suggested the moral decline of the period in American history through the interpersonal relationships among his characters. The situations in the lives of the characters show the worthlessness of materialism, the futile quest of Myrtle and Gatsby, and how America s moral values had diminished- through the actions of Daisy, Tom, Jordan, and Gatsby's party guests. Despite his newly acquired fortune, Gatsby still cannot afford his one true wish; therefore

rubber glove Essay Example

rubber glove Essay Example rubber glove Essay rubber glove Essay The basic raw material used in the manufacture of natural rubber latex exam gloves is latex concentrate which is produced from Hevea Brasiliensis natural latex using a steel tapping knife. Tapping is done at early dawn and the latex, collected in cups, is harvested several hours later and preserved with ammonia to stop it from premature coagulation. Because of its high water and non-rubber contents, about 70%, the latex is concentrated and purified by centrifugation to a 60% strength latex concentrate and stabilised using lauric soap for long term storage. The major producers of this atex is Thailand, Indonesia and Malaysia. Before the latex can be used for manufacturing gloves it must be mixed with a recipe of processing chemicals which include sulfur, zinc oxide, accelerators, pigments, stabilisers, dewebbing agent and antioxidant. These are mixed with the latex and allowed to mature over a period of 24-36 hours for the mix to cure. During this period the sulfur will become mixed with the rubber particles to yield a latex compound ready for dipping. The hand molds (or formers) suspended on a continuous moving chain are first dipped into a slurry of alcium nitrate solution and calcium carbonate. The nitrate is a latex coagulant while the carbonate is a former release agent. After the nitrate and carbonate has partially dried out, the molds are next dipped into the latex compound. At this stage the nitrate immediately coagulate a layer of latex over the mold. Because a thin layer of carbonate separates the film from the mold, it help both in removing the gloves from the molds as well as in preventing the gloves from sticking together. The freshly molded gloves in gel form are next leached in hot water to remove residual water- oluble protein and chemicals. The leaching process has became mandatory as a result of concern with allergic reactions associated with latex proteins. This step is essential to reduce residual extractable latex protein and the effectiveness is based on the amount of clean hot water used and dwell time. Beading brushes are run over the cuff ends to create a zone called beads which assist the users in donning the gloves. The next stage involves drying and curing the wet gloves inside a long and deep oven heated either electrically, by natural gas or hot air. Curing, or vulcanization, converts the gloves into an elastic state by causing the chemicals added during compounding to react with the rubber molecules in the latex. This is the most critical step as without curing the gloves will not be elastic as well as they will tear easily. Vulcanization is a chemical process, discovered by Charles Goodyear, by which the physical properties of natural or synthetic rubber are improved. It consists principally of heating rubber with sulfur and other substances, such as accelerators and activators. The sulfur does not simply dissolve or disperse in the rubber, but rather combines chemically, mostly in the form of cross-links (bridges) between rubber chain molecules and the sulfur atoms. On the other hand, accelerators and activators act as catalysts to initiate the process as well as boost the reaction at room temperatures. Cross-linking is analogous to net building using strings that are knotted together. The sulphur atoms reside in the nodes that link the rubber molecule chains. Just as a net provides strength and a network to catch fishes, ross-linked rubber in latex provides the base upon which gloves are moulded. vulcanlzea ruDDer nas nlgner tenslle strengtn ana reslstance to swelling ana abrasion, and is elastic over a greater range of temperatures. In other words, natural rubber without undergoing vulcanization will eventually become too brittle in cold weather or become sticky in hot weather. Upon exiting the oven the gloves are dipped once again into hot water to perform a dry film post-leaching wash to extract residual proteins and chemicals that bloomed to the glove surface. It has been established that a combination of wet and dry leaching has been very effective in removing residual proteins and chemicals and has significantly reduced the number of cases of protein allergies and sensitization. The leached gloves are then dipped into a slurry of corn starch and dried. This layer of corn starch assist in glove removal and donning. The final step of glove manufacturing involves stripping of the finished gloves from the molds using pneumatic air Jets. The now bare molds are then given a horough chemical wash and rinsing before entering the next dipping cycle. Typically a mold will be dipped 4-5 times in an hour and once a week they will be given a thorough scrub to remove built-up stains and residues. Periodically the molds are visually examined for defects and replaced. Stripped gloves are hot-air tumbled to even them out as well as remove detachable powder. They are batched in bins, tagged and sampled for inspection. Operators examine the samples for visual defects, measure their weights and dimensions and check them for air leaks. Batches hat pass the inspections are routed for direct packing. Those that fail are bagged for rework and retest. Passed gloves are also tested for physical properties. These are tensile strength and elongation at break before and after ageing to ensure they can withstand prolong storage and handling stress. All packed gloves are water tested for compliance to the maximum allowable leak failures called AQL. Batches that fail will be reworked or downgraded. Only gloves that meet the in-house specifications will be allowed to be shipped to customers warehouses.
