Cholesterol - Assignment Example Cholesterol bromination can be used to purify cholesterol (Barton, Miller & Young 98). In most cases, oxidation refers to the addition of the oxygen atom to a substance. However, in organic chemistry, oxidation refers to the loss of bond by carbon atom to hydrogen forming new bonds with other atoms. The overall reaction is characterized by loss of electron density hence loss of the electron. Cholesterol is capable of undergoing both autoxidation and photo-oxidation to produce oxysterols in each case. The common oxidants used for cholesterol oxidation are zinc and sodium dichromate. The first step involves the formation of the ketone, where the O double bond replaces the OH functional group. Then zinc is used to remove the bromine atoms (Stewart, Lee & Can 439). Debromination is the opposite of the bromination because it involves the removal of the bromine atoms from the organic molecule. It is one of the dehydrogenation reactions where cholesterol dibromide is boiled in the presence of alcoholic halide to produce the corresponding alkene molecule. The chemistry behind this reaction is that the bromine attached to the carbon in the alkyl bromide undergoes a reaction with hydrogen that is attached to the ÃŽ ²-carbon that releases the hydrogen bromide. The product of the reaction is the formation of a double bond between ÃŽ ± and ÃŽ ² carbon resulting into an alkene (House & Row 182). Isomerization is a process involving the transformation of a molecule into another with the same atoms but different arrangement. The new molecule is called an isomer. In the case of cholesterol, oxalic acid assists in shifting 5-Cholesten-3-one to a 4-Cholesten-3-one by shuffling of the position of the carbon-carbon double bonds. Oxalic acid provides the acidic medium that favors shifting and formation of a double bond to a new location leading to the formation of the conjugated system with the ketone group (Seager, Spencer & Slabaugh 123). Crystallization is the

Township Planning in and around Chennai City Limits Research Proposal

Township Planning in and around Chennai City Limits - Research Proposal Example With specific subject related colleges represented by Anna University and Madras Medical College. Despite its ongoing development as a leading commercial metropolis, Chennai is also responsible for housing 5% of the entire slum population of India, together with a significantly high migrant population.1 This proposal will outline a framework for consideration based on the principal that as a city Chennai needs to incorporate a great many factors into its attempts to expand and develop industrially, educationally and for the benefit of its existing residents and future population. In particular it will seek to demonstrate the advantages of recent city growth in the form of townships. How the city is developing and reinventing itself as a consequence of these new developments The literature for this research will broadly split into three categories. Each category will be the focus of the three fundamental chapters. With the fourth and final chapter dedicated to rationalizing the findings. The first category will focus on the history of Indian town planning. This will provide a context within which the current situation and consequences of modern day townships being developed throughout Chennai will be rationalized. It will explore the reminiscent British influence and the Victorian concept of municipality and how this was first established in Madras (now Chennai). Research Publications such as the Transformation of Housing Policy and other documentation sourced from the Indian Institute of Public Administration, together with books like Indian Government & PoliticsBy Sharma Manoj which detail the period of the 1960's amongst others as eras that can be defined as playing a major role in the development of urban planning models. The second category to be investigated will involve a demographic overview including the current economic and social situation in Chennai in the twenty first century. This will be achieved through the presentation of collated statistics the overall socio-economic situation of the population by illustrating the differences across the city and its outskirts. There have been a number of qualitative and quantative research studies carried out on the population of this particular city including Quality of Life of Migrant Households in Urban Slums, by S. Sundari, Alcohol Abuse Among The Coastal Communities In Chennai District, Tamil Nadu Tsunami Resource Centre, Prof. L. S. S. Manickam Ph.D. Dr. Joshi Basil PhD, An Adaptive Ecosystem Approach to Managing the Urban Environment for Human Health, Martin J. Bunch. The case for being able to demonstrate the current situation of the people of Chennai, their history of housing issues, poverty and deprivation as a result of demographic circumstance will help legitimise the overall picture of Chennai as a city whose population has suffered and continues to do so without the necessary changes to infrastructures a nd controls on building and residency issues. These statistics will be supported by a number of text based

Envisioning America & What Caused the Pueblo Revolt Essay - 2

Envisioning America & What Caused the Pueblo Revolt - Essay Example With this New England, we can rid our country of the offal that can work on the land whilst bringing riches to the emptied coffers of the Treasury. Moreover, the potential wealth from this country could launch more ships in the efforts to expand Her Majesty’s empire. Once the Treasury will bear the fruit of the rewards of this New England and we can rid our country of the criminal peasants stirring trouble in the North and Scotland, Her Majesty will be eternally grateful to our efforts in conquering this new territory. The only problem I can see in appropriating this New England to Her Majesty’s territory is the natives. I hear that there are nearly a million of them living between the Mississippi River and the Atlantic Ocean. On the journey to New England, I heard numerous stories from the other travellers of these natives being barbarians, worshipping pagan gods that wear no clothes. At worst, I heard that these natives were warriors engaging in cannibalism and anti Christian practice. However, on arrival to this abundant new territory, most surprising and most welcome have been the natives in their unconditional hospitality. Whilst unusual in appearance and their religious beliefs clearly far from the trueth, they are far removed from the barbarians and haughty people seen in pictures back in England. Indeed, they are friendly, loving and faithful and void of treason. Yet their religious practice is pagan and they lack enlightenment. What they don’t know at home in England is that there are many different tribes amongst these natives, all with different cultures and different practices. Their nature leads me to believe that we shall be able to reform their religious ways and be faithful to the Christian religion, but the task will not be easy. The different tribes believe in different gods and have developed

Future Law Enforcement Weapons Essay Example for Free

Future Law Enforcement Weapons Essay Everyday technology is taking advances in all fields of work forces, Especially Law Enforcement. Todays as well as future technology will make the jobs of those in the military and law enforcement easier as well as safer. As technology is breaking through, amendments 4 and 8 in the constitution need to be taken in consideration. The technologies may not be used to punish, and if it is searching equipment, a warrant is needed unless it will be used for sudden reasons of safety. In the future, instead of a normal squad car, someone might see a bulletproof truck. What is cool about it is that, they are strictly for the safety of police officers; they do not need to worry about a warrant, or hurting someone. This tool in the future would save officers lives. The bulletproof trucks are crash resistant/ damage resistant, during a high speed chase, and can possible handle a small missile fire. The portable radar system is a lightweight tool that sees through walls. This tool also promotes officer safety, it allows a building to be searched from the outside, detecting anything potentially dangerous on the inside. The officer would not have a problem with the 8th Amendment, this tool is not a weapon, it cannot be used to punish, restrain, or temporarily injure a suspect in anyway. Although the 4th Amendment would be needed to in consideration, because it is a tool that may be used to search private property. In order for Law enforcement to search another person’s property, a warrant is needed; it does not matter if the officers are searching from the inside or the outside, in this case the outside. Only when the safety of a person is threatened, may Law Enforcement use this tool without a warrant. The grill mount Launcher, is a tool that attaches to the vehicle, and it allows the police officer to shoot a GPS system onto another vehicle to track. This tool would be useful during a high speed chase; the suspect could get away, but completely unaware that their vehicle had a GPS that was tracking them. The Grill mount Launcher is strictly a tracking system; it does not violate the 4th or 8th Amendments. This tool does not having searching abilities, or the potential to hurt anybody. The officer should be free to use this tool any time a situation calls for it. The strobe lamp is a handheld tool with extremely bright lights, which causes temporary blindness. This tool promotes citizen safety, this tool is not a deadly weapon, it does not have a potential danger for a by-stander; In addition this tool most likely not kill the suspect, the strobe lamp provides alternate options for a police officer to take someone into custody, other than a gun, or handcuffs. This tool could not possibly violate the 4th amendment. A weapon is any device used for attack or defense against an opponent. Since the strobe lamp does cause pain, and the suspect to temporarily lose their vision, it is considered a weapon, which means an officer has to follow the 8thamendment. A Law Enforcement officer cannot use this weapon on a suspect because they deserve it, only may this tool be used, if the suspect is posing an immediate threat on the officer or another person. The Automatic License Plate Recognition Device allows police officer to check thousands of license plates, to determine if vehicles are stolen, if registered owners are wanted, if driver’s licenses are expired or revoked. The system also takes a picture of the car license plate and registers the code into a database. This tool allows the officer possibly find the name and history of the suspect easily. This tool is similar to the grill Mount Launcher GPS as far as tracking the suspect. This tool has no relation to the 4th and the 8th amendments, it does not harm, and it is only for Law Enforcement benefit only. Most of today’s Law enforcement technology does have to be used carefully, in order to avoid problems with Amendments of the Constitution, but ultimately they provide non-lethal weapon options to use on suspects, citizen safety, in addition to Police Officer safety,

A Tragic Hero :: Character, Brutus, Cassius, Caesar

A tragic hero is defined as a person of high social rank, who has a tragic flaw or flaws that lead to their downfall. These heroes’ downfalls are usually either complete ruin or death. Tragic heroes face their downfall with courage and dignity. While many characters in Julius Caesar could fit these conditions, the person who fits the role of a tragic hero the best is Marcus Brutus. Brutus develops into a tragic hero throughout the play, and this is shown though his qualifications of a tragic hero, his high status, his tragic flaws, and his courage in the face of his death. Brutus has high social status in Rome. Brutus is a senator, and a popular one at that. Cassius says that â€Å"many of the best respect in Rome... have wished that noble Brutus had his eyes† (1103). Many people look up to Brutus, and wish he would help with their problems. Brutus has enough social status and wealth to hire six servants (1097). Brutus’s wife, Portia, is â€Å"Cato’s daughter†, a highly respected man (1124). IT would take someone of high status to marry a daughter of Cato’s. Portia asks if Brutus thinks she is â€Å"no stronger than [her] sex, being so fathered and so husbanded† (1124). This implies that Brutus is a man on a near caliber to that of her father. Even after Brutus is run out of Rome, he keeps his high status by becoming a general. One of the qualities of being a tragic hero is high social status, and Brutus has this quality. Brutus has several tragic flaws. One of these tragic flaws is how he trusts people a lot. Brutus says that he â€Å"know[s] that we shall have [Antony] well to a friend† (1140). He trusts Antony will be a friend of the conspirators, yet he seems to not realize that Antony is obliviously against them, because they killed his friend. Brutus trusts Antony so much, that he lets Antony speak to the public alone. Antony turns the people against Brutus and the conspirators, leading to the wars where Brutus takes his own life. Brutus also receives letters, supposedly from the people of Rome. As he reads the letter out loud, Brutus remarks â€Å"‘Speak, strike, redress!’ Am I entreated to speak and strike? O Rome, I make thee promise, if thy redress will follow, thy receivest thy full petition at the hand of Brutus† (1118).

How do the later war poets differ in their treatment of war Essay

How do the later war poets differ in their treatment of war from early war poets? World War I was noticeable for the vast amounts of poetry that was produced from many of the soldiers. The poets wrote vastly over the years 1914-1918 and they all expressed many different opinions. It was a way of getting their views across to other people. Some of the poems even made aware of the fact and the true horror of the war. During the first half of World War I, the poems that were produced had a very patriotic and glorious view to them. As the war progressed, the poems became more bitter as the true extent of what was really going on, was unveiled. Some of the poets we will be looking at include Wilfred Owen and Laurence Binyon. For early war poetry, we have studied four poems. These are: 'The Soldier', 'Rendezvous', 'For the Fallen', and 'Fall-In'. The poets who wrote these poems are: Laurence Binyon, Rupert Brooke, Alan Seeger and Harold Begbie. These poems in general, had a very glorious, patriotic feel to them. Because the war had just started, people did not know what the war was going to be like. Nor did they no how many people would be killed. These poems were used as propaganda by the government so that many young men would enrole for the army. 'For the Fallen' is an elegy. Being an elegy during the war, you might have been mistaken for thinking that it is not a very glorious poem. But this poem celebrates the death of the soldiers and is celebrating the work that they have done for their country. This poem gives a personification of England and describes the soldiers when they were young. This poem constantly uses alliteration throughout. 'They fell with their faces to the foe' is a good example. Th... ...Hero' is a poem about a mother receiving the bad news that her son is dead. This poem has an AABBBCCDEDEFF rhyme scheme. In the second verse, the rhyme scheme has changed. This is because Sasson wanted a change of meaning in the poem. 'Suicide in the Trenches' has a regular and constant rhyme scheme. Every two lines are a rhyming couplet. This keeps the flow of the poem constant. It is criticizing the British public who cheer for the soldiers, just as they are about to go to war, but the public themselves, do not know what the soldiers are about to face. It is a very bitter poem. 'They' is another very bitter poem written by Sasson. This time, Sasson is criticizing the church for making the war sound like a crusade. The poem uses a rhyme scheme of ABABCCDEDEFF. It has two versus and both end in a rhyming couplet. This is used for impact and emphasis.

Helping Chinese Consumers Essay

QuarkMan Technology was founded in 2012 by David Yuan. As the Chinese domestic consumption continues to grow at a rapid speed, consumers need a reliable source for independent and impartial review of products to find the quality and functionality. The mission of the company is one of â€Å"unveiling products’ essence in an independent, professional, and powerful way.† The two core principles are â€Å"Independence† and â€Å"Fairness†. QuarkMan has set up two business units, Information Advisory and Media. The reports and data obtained by the testing of products are handled by the Information Advisory unit and the Media unit takes this information and displays it in a user friendly way so that consumers can make educated decisions. QuarkMan Media is further divided into Jancr which is the consumer goods testing division and China Consumer Report which is the communication division responsible for settling disputes between the consumer and manufacturer. SWOT ANALYSIS for QuarkMan Strengths Manages their own lab and return team Strong relationship with third party labs and research institution labs State of the art testing lab with 400 pieces of equipment and 3000 square meters External expert network from numerous industries In-house lab is a stand-along profitable business unit which finances the media unit Weaknesses Hard for an independent and fair media company to be profitable in China In order to remain independent, advertisements on their website is not an option Majority of the testing resources are owned by the government affiliated consumer associations, industry associations and government research institutes A big chunk of the capacity has a very low utilization rate Takes 2-3 weeks for QuarkMan to deliver one product review and others longer QuarkMan struggling with capacity issues Opportunities No mature player conducting comparative tests and analysis across different industries The third party testing market was controlled by the government but has now become a huge and rapidly growing market QuarkMan currently handling six product categories but have the opportunity to handle more Exhibit 4 – Private only handles 10% of the current market share Threats Private sector is growing at a CAGR of 25% Speed is a key factor for the high growth rate New players in the market have gained decent traffic from more frequent content releases Exhibit 4 – Foreign markets only handle 25% of the current market share Problem/Decision Statement How can QuarkMan influence consumer perception of their brand and business values and thus gain their trust and business? Identification of Alternatives Consider advertisements as a revenue stream with the use of a 3rd party to manage the sale and pay a portion back to QuarkMan so independency and objectivity is upheld. Use these funds to mark the business philosophy of QuarkMan to gain additional market share. Obtain additional financing through other interested parties and use revenues to promote the business model and use additional financing funds to expand testing resources and improve turnaround time and reach more consumers Critical Issues Impact on current and potential consumers and their ability to trust QuarkMan if they attempt to raise revenue revenues through advertising The use of a 3rd party to manage advertisement while increasing revenue and the effects on their ability to stay independent and transparent to the consumer Significant lead time to bring products to market and the limit number of product reviews that can be completed times. The use of a 3rd party to manage advertising would directly go against the company’s core principles of Independence and fairness thus leading to more mistrust. Analysis Consider advertisements as a revenue stream with the use of a 3rd party to manage the sale and pay a portion back to QuarkMan so independency and objectivity is upheld. Use these funds to mark the business philosophy of QuarkMan to gain additional market share. The current market has a distrust of the industry because of the lack of transparency and the blurred lines between the agency reviewing the produce and the product manufactures. The current Chinese consumer agency is not transparent and the government plays such a significant role in the reviews because of this the consumers do not trust any consumer reports. QuarkMan’s guiding principles of independence and fairness will be viewed as conflicting with any advertisement from a manufacturing. This conflict will add to more doubt from their consumers. Obtain additional financing through other interested parties and use revenues to promote the business model and use additional financing funds to expand testing resources and improve turnaround time and reach more consumers This alternative would allow for additional revenues while not compromising their independence and fairness. QuarkMan can continue to market their product and services through current media channels and bring awareness to their strong brand name and transparency while setting them apart from the current competition. This will help to generate long term customer loyalty. Additional revenues can strengthen their 3rd party testing environment and help to reduce the lead times and number of products able to be reviewed at one time. They can further expand the types of products they review and be able to reach more potential customers. Recommendation The recommendation based on the entire analysis would be to obtain additional financing through other interested parties and use revenues to promote the business model and expand testing resources to improve turnaround time and reach more consumers. This alternative would allow for additional revenues while not compromising their independence and fairness. QuarkMan can continue to market their product and services through current media channels and bring awareness to their strong brand name and transparency while setting them apart from the current competition. This will help to generate long term customer loyalty. Additional revenues can strengthen their 3rd party testing environment and help to reduce the lead times and number of products able to be reviewed at one time. They can further expand the types of products they review and be able to reach more potential customers.
