Chemical Engineering :: essays papers

Chemical Engineering What exactly is a chemical engineer? Many would say that it is simply a chemist who builds things or an engineer who makes chemicals. However, neither of these statements is completely true. The term chemical engineer is not meant to actually describe what it is a chemical engineer does, but to describe what sets it aside from the other branches of engineering civil, mechanical, and galvanizing. On average, chemical engineers are numerically the smallest but also the highest paid. It is not a profession the must dwell on the early(prenominal) for comfort and support, for its greatest accomplishments are still yet to come. Chemical engineering, a prominent and growing career, requires a detailed understanding of the how and why chemical processes take a crap and also how they can be further improved. To develop new improvised methods for these processes to function more useful and economical, a chemical engineer uses theories and laws of chemistry. They a re, however, often referred to as the universal engineer because they must not only have a broad knowledge of chemistry and physics but also of mechanical and electrical engineering. The Industrial Revolution sparked a new curiosity and need for chemical engineering. In order for certain industries to sustain growth, the production of chemicals became of great importance, especially sulfuric acid. In attempts to improve the process of making this chemical, much time, m wizardy and effort was put into it. By this, the slightest savings led to large profits because of the vast quantities of sulfuric acid consumed by industries (Pafko, Setting Stage). To create the much needed sulfuric acid, a long used and little understood method was used, the lead-chamber method. During this process, one of the main ingredients, nitrate, was often mostly lost into the environment. Because nitrate must be imported, and the process used so much of it, it became very costly. Improvement was needed in order for sulfuric acid to be made at a much lower cost, since it was so widely used (Pafko, Setting Stage).In the late 1800s, Americans became fascinated with intelligence service that was coming over from across the Atlantic. Though it was not the advancements in the chemical engineering field that so interested them, it was the news of a serial killer Jack the Ripper. It seamed as though the surfacing of chemical engineering would just slip by unnoticed.

Americans and Individualism Essay -- essays research papers

The United States of America is the land of the free, the land ofopportunity, the wealthiest country in the world, a country that half themodern world is modeled after. Its President is referred to as the "Leaderof the free world". Thousands of people come to this country every year,learning about the country in hopes of becoming citizens. William Hudson inhis book American country in Peril talks about the seven biggestchallenges to this democratic nation.Individualism can be seen as a gift or a curse, depending on the context inwhich it occurs. Because modern society finds it important that people thinkindependently, decide autonomously and take personal initiatives, theconcept of individualization has acquired a positive connotation. However, individualization is also linked with the tendency to crawfish out from social lifeand turn in towards oneself. Alexis de Tocqueville described individualismas the cool and considered attitude which drives people to withdraw into asmall, enclosed world consisting of their family and a few select friends,leaving the rest of society to its bear devices.The most obvious problem stemming from the process of individualism is of asocio-economic nature and concerns the problem of solidarity. If the linkbetween the community and the individual becomes less strong, to what extentwill an individual experience social problems, in which he or she is notimmediately implicated, as his or her problems? To what extent are people inan individualistic society prepared to consider the problems of others astheir own? This is a crucial question for society since it places thelegitimacy of many social institutions and political structures in question.Whoever accepts that individualism is a fact will consider political life tobe an incessant clash of interests on the part of people who are only in itfor the sake of personal power or an attach in personal fortune. Whilethey may be fine, responsible people in private life, in thei r attitude togovernment they are like infants, concerned only in themselves and whatthey consume, howling for more, and not concerned at all about the moralityof using government as a middleman to forcibly take what they desire fromtheir fellow-citizens.

On the other, it is impossible to stop shortly of this democracy andgo back to aristocracy. This is because democratic equality also conforms tonature.

We cannot attain the end of thismovement, for it would mean subjecting nature completely and dehumanizingman. Escaping democracy is not an option. We can never possibly makedemocracy completely "real", and we must(prenominal) not try. We can and must moderatedemocracy, limit it, sober down its hostility to nature, all the whilebenefiting from its conformity to nature. To moderate democracy so as itconforms with human nature, to limit it insofar as it is contrary to it,such is the sovereign art on which depend the prosperity and morality of ademocracy.

Theme of Deception in Much Ado About Nothing Essay -- Much Ado About N

Theme of Deception in Much Ado About Nothing to each one of the briny char chipers in Much Ado About Nothing is the victim of deception, and it is because they are deceived that they act in the ways that they do. Although the central deception is directed against Claudio in an attempt to destroy his relationship with Hero, it is the deceptions involving Beatrice and Benedick which provides the plays dramatic focus. Nearly every character in the play at some point has to make inferences from what he or she sees, has been told or overhears. Likewise, nearly every character in the play at some point plays a part of consciously pretending to be what they are not. The idea of acting and the illusion it creates is rarely far from the surface - Don Pedro acts to Hero, Don John acts the part of an honest friend, concerned for his brothers and Claudios honour Leonato and his family act as if Hero were dead, encouraged to this deception by, of all people, the Friar who feels that deception ma y be the way to get at truth and all the main characters in the plot pretend to Benedick and Beatrice so convincingly that they reverse their normal attitudes to each other. In I.1 Don Pedro offers to play Claudio and win Hero for him. This curriculum is overheard, and misreported to Antonio. His excited retailing of the false news of Don Pedros love for Hero to Leonato is, however, not without some caution the news will be good as the reddent stamps them but the have a good cover, they show well outward (I.2.6). Leonato shows a sense here that he could well do with later in the play Hath the fellow any wit that told you this? . . . we will hold it as a dream . . . peradventure this be true. Admittedly he does not question the good sharp ... ...ne else in the play the power of language to alter reality, and the issues of conscious or unconscious deceit. It shouldnt be forgotten that in the body of the play those who are masters of a language of extraordinary wit and polish - lan guage that seems to guarantee rationality and good judgement - get things almost completely wrong. The resolution of the play comes via the dresser of the people whose discourse is an assault on language, who are dismissed - by Leonato - as tedious when they should be patiently listened to. But, as Borachio says what your wisdoms could not discover, these shallow fools have brought to light (V.1.221-222). And even more disturbing, that resolution comes by mere accident by the chance overhearing of a conversation. Works CitedShakespeare, William. Much Ado about Nothing. Ed. A.R. Humphreys.

Principle or Personal? Essay -- American History, Joseph MacCarthy

During the Cold War, members of the United States govern ment, army, and even citizens were accused by Senator Joseph McCarthy of being communistic and Soviet spies and sympathizers. These trials persisted through the fifties until Senator McCarthy was excoriated by Congress. Similarly, during the seventeenth century, many inhabitants of Salem, Massachusetts were accused of witchcraft, with a total of nineteen hangings during what came to be called the Salem Witch Trials. These trials were conducted in a similar fashion as Senator McCarthys hearings, and many of these accusations were not fought because the circumstances of the time made these claims possible. Arthur Millers The Crucible sheds new luminousness on the mysterious Salem Witch Trials and why so many of the small community were hanged. Though some Salemites believed the Devil had come to Salem, Millers The Crucible depicts the witch trials as motivated by personal interests of greed, jealousy, and pride.To cover their own personal want, some men of Salem, such as Mr. Putnam and Dr. Walcott, accuse men and women of witchcraft in an attempt to buy their land or receive some compensation once the land-holder is convicted. Mr. Putnam, a key example of the greed in Salem, first demonstrates his when Proctor says that he needs to leave Parris house to move wood in Act One. When Proctor tells Putnam that Proctor is dragging wood from the timber by the riverside, Putnam responds, Why, we are surely gone wild this year. What anarchy is this? That tract is in my bounds, its in my bounds, Mr. Proctor (30). This response prepares the audience for Act Three, for Putnam would ulterior manipulate the judges caught up in the witchcraft craze to accuse a key land holder in an attempt to a... ...g to other villages, meet as an actual crucible would do with glass heated to extreme temperatures. Despite this, mass hysteria has still occurred throughout the history of the United States, from the Senator McCarthys Communist trials of the seventies to even modern day, with many Americans drawing suspicions from stereotypes of terrorists. Though todays suspicions often do not end in hangings, leadership figures in society continue to exploit human natures emotions to get what these men desire. These influential men are motivated as the men of Salem were greed drove them to acquire more jealousy, for revenge pride, for the sake of being right. Even if these influential men say they act out of commandment versus personal reasons, such as those described previously, the opportunities for these men to exploit the people in a state panic will surely not go unused.

There are two main goals when it comes to the juvenile justice system reducing crime and rehabilitation. Status offenders cases and delinquent cases differ when it comes to processing and when it is time to face a judge in court. A delinquent offense is an act committed by a juvenile for which they can be tried as an adult and be prosecuted in criminal court. Running away from home, truancy, curfew violation and underage drinking are examples of status offenses. They arent punished with such harshness as a delinquent offender would.
