Analysis Of Arthur Miller s The Crucible - 2138 Words

Crucible Character Essay - John Proctor #6 In Arthur Miller’s â€Å"The Crucible† the protagonist is a man by the name of John Proctor. Proctor is a very complex character because he doesn t have the cleanest history. He is a man in about his forties who had committed the sin of cheating on his wife with a young girl. This act of his gives a bad first impression to the reader. Proctor however does try to become a better man and do the right thing to save his wife s life, which changes feelings about him as he is then seen as almost a savior. This controversial character faces many obstacles that go against him in trying to save his wife. Early on in the story Proctor is challenged with letting a young naive girl, by the name of†¦show more content†¦Proctor feels that the only way to prove his wife innocent is to reveal his personal relationship with Abigail, so he can reason that Abigail only accused his wife because she wants to be with him and have her out of the picture. This sets up the main feud with Procter being the protagonist and Abigail being his antagonist. John shows his attempt to make things right in his decisions. Instead of being seduced by Abigail again he has self control and tells her that it is over. This choice Proctor makes early on in the story demonstrates his desire to correct his mistakes. It is never more evident that Proctor is trying do good than when he confesses to lechery to save his wife. He tells the judge that he slept with underage Abigail and that is why she accused his wife, so she can get rid of her. Proctor’s decision to not say anything when asked to confess to witchcraft reveals how much he cares about his reputation. He would rather be hung than be known to everyone as a man who performed whichcraft. Proctor is pretty successful in changing his image. He positively changes himself. He goes from being a man who committed lechery, which is sleeping with someone underaged, to a heroic man who dies with honor because he didn t lie and confess to witchcraft to save himself from being hung. He is the most changed character in the story and is controversial because it is debatable whether he is truly a hero

Heavy Metals - 916 Words

Heavy metals such as arsenic (metalloid), mercury, lead, and cadmium have a rich history throughout the world. From Ancient Rome to the Vietnamese War, heavy metals have been used in many different ways, sometimes leading people to death or illness. This research essay will go through the history of the above-mentioned metals, how they were used, and how they can affect people. Arsenic Among the first uses of arsenic in in 19th century was in taxidermy and painting (Cooksey 2012). Soon after, it was determined that arsenic was poisonous leading to the passing of the Arsenic Act in 1854 which required a signature for buying arsenic (Cooksey 2012). Despite this people continued to use arsenic for dyes and taxidermy. Many people grew†¦show more content†¦The mercury that was ingested in Japan came in the form of methyl mercury. Methyl mercury can cross the blood-brain barrier and cause ataxia, sensory disturbances, and changes in mental state (Cooksey 2012). Lead In the past, lead was used in smelting, and it was known that the vapors can be deadly (Cooksey 2012). In ancient Rome, lead containers were used to hold food and drink and was a constant source of chronic toxicity for many years (Cooksey 2012). Although people were recognizing the effects of lead, it wasn’t until after 1950 that legislation banned lead in food and drink cans (Cooksey 2012). Today, lead poisoning is a huge concern in China as the country becomes more industrialized and the production and use of lead increases (Hou et al. 2013). According to Hou et. al, lead can affect many organs and destroy functions of the nervous system (2013). A person can accumulate lead in their body from the environment, and it tends to stay there. This means that younger children are more vulnerable the longer they are exposed to lead. Children’s blood brain barriers are also not fully developed yet, making them more susceptible to lead poisoning (Hou et al. 2013). I t has been observed that lead can impair growth, memory, intelligence, and behavior in these children (Hou et al. 2013). Hou et al, conducted a study to observe the trend between blood lead levels and cognitive development of children (2013). They found that â€Å"blood lead levels had an obviousShow MoreRelatedA Report On Heavy Metal Distribution1173 Words   |  5 PagesHeavy metal distribution in sediments around Kallur Mandli and Sagar road Industial estate Shimoga, Karnataka, India.

Thermoelectric Cooling Prosthetic Premium

Question: Discuss about theThermoelectric Cooling Prosthetic Premium. Answer: Introduction There is an approximation of 1 amputee per 1,000 people in Australia. Furthermore, there are twenty thousand amputees in excess who reside in Australia (Anon, 2016). More than 50% of them went through the trans-tibial amputation (Anon, 2016). Most of them have reported the challenge of the overheating prosthetic leg socket. Our team, the Techs has developed a prosthetic device known as the Thermoelectric Cooling Prosthetic premium (TCP-premium) that automatically detects hyperthermia at the site and cools accordingly maintaining the normal body temperature (Cold Thermoelectrics 2013, pp.669-669). This project was a brainchild of collective responsibility and deliberation with the interests of the amputees at heart. Furthermore, an idea like this has never been born in Australia. There is a bulk of materials needed for the production of these prosthetics that are very helpful for the amputees. They are also meant to be cheap for consumption. Objectives Prevention of complications of overheating prosthetic sockets like skin burns. Reducing the cost of purchasing prosthetics. Promoting comfortability of the amputees in Australia. To ease the use of prosthetics. Promote high-quality production and durability. Produce water resistant, shock protective and fitting prosthetics (Aaos.org, 2016). Approach and Methods The criteria of design were the cooling power and weight system as well as simplicity and durability. Again, the project is open to qualitative and quantitative methods of research. The research on electrical systems concluded that 5500mAh batteries of 7.5V would be used. The methods of control, thermoelectrics, the interface of the user and the transfer of heat mechanics were also researched. The other approach is the use of electricity in making different designs and shapes to provide a broad range of products. Again, the demonstration of use shall be availed on the media for the consumers. Once supplied for use, questionnaires and surveys shall be used to evaluate the quality of TCP-premium.
