Liberty, Property, Security, and Resistance to Oppression Essay

In recent times, France has experienced monumental events that foreshadow quite a different future for France, and the beginning of a new revolutionary regime. Disorder and theft have unfortunately accompanied violent events and in response: the formation of the National Guard. The Guard is composed of professional soldiers, foreign mercenaries, merchant and shopkeepers’ sons, and sons of the most comfortable master workers and journeymen, and other â€Å"active† tax paying citizens of the middle class. With such an important role as to maintain order and law in France and to protect the Constitution, it is presumed that the Commander General of this Guard must be one whom is well versed in commanding a large force. I, Marquis de Lafayette, have this experience. Having been granted the position of Major General and forming close relations with General George Washington in the American Revolution, I performed to the best of my ability on the terms of no pay and as a volunteer. I received a formal recognition from the United States Congress for my services in the Rhode Island expedition, have gained much respect for my tactics in battle, and ensured the Revolution was all but won with my success in the Battle of Yorktown. As a key component in the success of the American Revolution and as a General in the French Army, I ask of you all to now grant me the position of Commander General of the National Guard of Paris. Furthermore, I ask for your support of an important piece of legislature, The Declaration of Rights of Man and of the Citizen. This document sets forth â€Å"in a solemn declaration the natural, unalienable, and sacred rights of man, in order that this declaration, being constantly before all the members of the Social body, shall remind [you] continually of [your] rights and duties; in order that the acts of the legislative power, as well as those of the executive power, may be compared at any moment with the objects and purposes of all political institutions and may thus be more respected, and, lastly, in order that the grievances of the citizens, based hereafter upon simple and incontestable principles, shall tend to the maintenance of the constitution and redound to the happiness of all,† (Declaration of Rights of Man and of the Citizen). Do not let France devolve into anarchy, and let us continue to exercise our universal and natural rights for the benefit of and all and the future of France!

The Princess Bride

The Princess Bride is a 1987 American film, based on the 1973 novel of the same name written by William Goldman, combining comedy, adventure, romance, and fantasy. The film was directed by Rob Reiner from a screenplay by Goldman also the book’s author. The story is presented in the movie as a book being read by a grandfather to his sick grandson, this technique effectively keeping intact this novel's narrative style. This movie is number 88 on The American Film Institute's (AFI) â€Å"AFI's 100 Years†¦ 100 Passions† listing the 100 greatest film love stories of all time. As said the movie’s novel like feels it done by a grandfather reading a book to his grandson, who would rather be playing his video game, then to listen to a story about love. The story takes place in a fictional world of Florin is about a beautiful woman named Buttercup who orders around a farm boy until the day when she realizes, that she loves him. She wants to live happily ever after with him, but then evil forces intervene. Buttercup learns that her one true love Westley her farm boy was killed. Five years later we find Buttercup ready to marry the Evil prince Humperdinck. She is kidnapped by a trio of bandits, who want to start war between Gilda and Florin. The trio is tallied by the Dread Pirate Roberts. Who is there to save the princess, who is this heroic man in black? This movie is witty and sassy without going too far over the top. Reiner manages a task of creating a movie that at the same time parodies a genre while also celebrating and participating in it. Despite the irony and the fantastic setting we come to care about the individuals even the trio of bandits. The instant the princess is kidnapped by agents of the evil Prince Humperdinck reveals itself as a spoof of sword and sorcery movies, yet the film somehow manages to appeal to all viewers. While the younger viewers will sit fascinated by the thrilling action scenes like the sword fight, and the adults, will be laughing with movie at one scene after another. This film is funny not only because they contain comedy, but because Reiner does justice to the underlying form of his story. And those who search films that can be enjoyed by all members of their family this movie is it. All of them will enjoy it family members ranging from grammar school kid, to teenagers, ,mom and dad, and even grandma and grandpa will have a few laughs. There may be nothing better than this motion picture, which celebrates fairy tales and true love. , The Princess Bride can still be enjoyed on the simple level of the story of a princess being rescued by her one true love. The average family film is targeted mainly at children, with a few elements thrown in to go over the young children’s heads that appeal to their parents. The crafting of The Princess Bride, however, is far finer. Nearly every aspect of the film delights all possible viewers. For example the sword fight between Inigo and Westly, offers equal thrills to the viewers of all ages even though the verbal banter that accompanies the struggle will resonate more with the older viewers. The choice of actors is only another plus for this movie for this already great movie , Robin Wright and Cary Elwes were selected as much for their good looks as for their acting ability, and they prove that. They have great chemistry that just beams off the screen. Wright, despite being California bred, delivers a perfect British accent. Elwes is equally at home with this comedic, action, and drama role. Mandy Patankin, playing Inigo, matches Elwes' athleticism and develops a character that is instantly sympathetic regardless of originally being a â€Å"bad guy†. Andre the Giant represents the mighty Fezzik as a lovable giant, and Wallace Shawn is hilarious as the narcissistic Vizzini, whose end is inconceivable. Chris Sarandon takes Humperdinck's arrogance to amazing levels. Since the release from over 20 years ago, The Princess Bride has often been copied, but never equaled. Perhaps the most successful movie to capture its spirit was the animated Shrek. The Princess Bride is an unparalleled achievement – a modern classic that will be enjoyed for generations to come. All in all the movie is a brilliant with the acting and comic wit is what makes the movie great. All though the movie is over twenty years old with makes the special effects nothing special. This movie has heart that is scene between Westly and his one true love Buttercup. All of the aspects add up to make one hreafelt comedy that will have you repeating lines in no time. This movie gets an inconceivable 4. 5 out of five stars.

Impact of Technology Essay

Every day we cannot live without technology. We wake up in the morning, we take a bath, we have breakfast, we do our daily activities, and all are affected by something called technology. From the simplest form of it until the most complex one, technology filled our daily life. The famous phrase â€Å"Information Technology† of course is one of the forms of technology. Before we continue talking about technology, we must know its definition. Shortly, technology is something related to science and engineering, which is used by the human or other creatures in dealing with their environment, to make their life easier. The technology develops fast. From the ancient age to the modern age, there are billions of its products that have made our life easier. In prehistoric age, the ancient human created the tools made of stone. They also invented the wheel, which is very important to the next centuries. Imagine that there weren’t any invention of wheel. We must give a lot of energy to move our goods from one place to another. Many centuries later, there are a lot of important inventions for human’s life, such as the invention of telephone. Using it, we may communicate through long distances. And the latest technology which has given many changes to the world and is still being developed is the information technology. The development of technology gives some impacts to human beings and the other creatures. The positive impact is, it makes our life easier. Without the inventions of technology, I think we would live our lives just like the prehistoric men did. Technology, just like the other things in this world, also has negative impacts. I’ll give you three examples. First, technology takes out the filters, like social filter, cultural filter, and religious filter. We can see in Internet technology. Internet is a medium in which no filter and censorship. Without parental guidance, your children may consume inappropriate materials from the Internet. The second one is the decrease of your social skills. Too much usage of technology makes you more antisocial. In the past, children used to play traditional games with their friends outside the house. But now they prefer playing video games in their own room, all by themselves. The easy access of technology also makes you too dependent to it. In the past, our people had more memorizing skills. They had to memorize things, because there was no tool to use to record things, except notebooks (the original phrase of notebook, not the portable computer). But nowadays, by using the computer, you can save any information you want in its memory to retrieve it in another day. In advance, by using the Internet connection, you may search any information you need through any search engine like Google, Yahoo, Altavista instantly. Dealing with those negative impacts, what can we do? First, we must be aware of them. We must be aware that technology could also cause bad things. After that, we must give the people knowledge of those negative impacts and how to deal with them. The government also has to do some actions about this. They must give some regulations relating with the press and the media. It is just need to be done to protect our society, not to restrain the press. And then, to increase the social skills, we must create the real community; build the real network, makes friends in the real world, of course not in the cyber world. By doing that, it will take us back to our nature as social creatures.

Cold War Research Paper Example | Topics and Well Written Essays - 1000 words

Cold War - Research Paper Example Communist world except China polarised with Soviet Union whereas the most of the democratic countries tied up with United States during this period. Most of the Eastern European countries were under communist administration during cold war and Soviet Union succeeded in bringing all of them under their umbrella, forming an Eastern Bloc whereas the Western European countries were mostly democratic in nature and hence they joined hand in hand with America during the cold war era. Even though, the militaries of these superpowers never clashed directly each other, there were too many proxy wars, espionage, propaganda, conventional and nuclear arms races, appeals to neutral nations, rivalry at sports events, and technological competitions such as the Space Race etc between these superpowers during the cold war era. This paper briefly analyses different dimensions of cold war. The term â€Å"Cold War† was first used in 1947 by Bernard Baruch, senior advisor to Harry Truman, the 33rd president of the United States, in reference to the frequently occurring and exacerbating crises between the United States and the former Soviet Union, despite having fought side-by-side against Nazi Germany in the Second World War. ... Nuclear arms race and the struggle for domination in the space missions were too much during the cold war era. â€Å"In 1992, a Soviet defector revealed to Western intelligence that he had overseen an extensive, illegal programme to develop smallpox into a highly effective biological weapon† (Flight). Moreover, the secret agencies in these countries also played their role effectively to strengthen the cold war. During the cold war era â€Å"the KGB, the 'sword and the shield' of the USSR, pitted its wits against its principal adversaries - the Central Intelligence Agency of the United States (CIA) and the British Secret Intelligence Service (SIS)† (Knightley) Even though, Germany, Britain and France were major forces prior to Second World War, after the Second World War, only America and Soviet Union did emerge as the world’s superpowers. The friendship between America and Soviet Union during the Second World War was only to destroy their common enemy Nazi German y. â€Å"In fact, one of America’s leading generals, Patton, stated that he felt that the Allied army should unite with what was left of the Wehrmacht in 1945, utilize the military genius and fight the oncoming Soviet Red Army† (What was the Cold War?). In short, even though America and Soviet Union cooperated in the fight against Nazi Germany, they never wasted any opportunities to blame each other. It was difficult for other countries to stay alone without seeking help from any of these superpowers at that time. Some countries like India, Yugoslavia, Egypt etc were tried to form another political bloc in the name of Non Aligned Movement (NAM), in order to keep equal distance with the two major superpowers. NAM started its

THE ARTICLES AND THE MEMORANDUM FORM A CONTRACT BETWEEN THE COMPANY Essay

THE ARTICLES AND THE MEMORANDUM FORM A CONTRACT BETWEEN THE COMPANY AND ITS MEMBERS. DISCUSS WITH REFERENCE TO RELEVANT STATU - Essay Example In this regard, the law relative to the memorandum of association prior to the enactment of the Companies Act 2006 is relevant to this study. Suffice it to say for present purposes that the extent to which the articles and memorandum forms a contract between the members and the company are reflected by the functions of each document. The memorandum’s functions have been altered, but its historical significance continue to be applicable as it has been resurrected and placed within the articles of association. Prior to the implementation of the Companies Act 2006, the memorandum defined the company’s external charter while the articles define the company’s internal charter. Ultimately, the memorandum and articles of association functioned together to determine the member’s commitment to the company’s goals and objectives and how the members will and can facilitate those goals and objectives. ... Instead of referring to the memorandum and articles of association, it merely attributes the contractual basis to the company’s constitution. Elsewhere in the 2006 Act, the company’s constitution is described as the articles of association. This essay analyses the contractual role of the articles and memorandum association in binding the members to company. I. The Memorandum of Association A. The Contractual Nature of the Memorandum of Association Prior to the Companies Act 2006 All UK companies are required to have a memorandum of association.5 Under the Companies Act 1985, the memorandum of association was required to specifically state the company’s objects and constitution.6 Recent reforms promulgated by the Companies Act 2006 have effectively reduced the memorandum of association to a mere shell of its former contractual significance. The current memorandum of association is no more than a simple instrument reflecting basic information such as the companyâ⠂¬â„¢s name, its registered office in the UK, share capital and shareholder liability. Even so, the memorandum of association has historical significance in that its main contractual basis has been transferred to the articles of association. Therefore the common law relative to the members’ commitment to the company’s objects under the memorandum of association are now relevant to the same commitment under the articles of association. Moreover, the share capital and limitation of liability as stated in the memorandum of association are also important parts of the members’ contractual relationship with the company that they form. Under the Companies Act 1985, the Memorandum of Association set out the objects of the company and the purposes for which it was formed.7 Section 2 also provides

Presently, Myanmar is facing various kinds of social and economic tensions, which have hampered the national unity of the country. This has led to a major downfall in the economic development and decrease in various economic opportunities. 90 percent of the population follows Buddhism and the cultural and social values are based on Theravada Buddhism. Gender biasedness is also prevalent to a large extent in the Myanmar society (BEWG, 2011). The country has been facing severe challenges because initially, it was under the control of the military regime, which has compelled the people to adapt to a particular lifestyle. Firstly, the management of CIC should understand and analyze the cultural variations in Myanmar which will help the company in studying the attitude and behavior of the common people. Secondly, the company should adopt several techniques which will help in understanding marketing dynamics and also adjust to it accordingly. Modeling techniques like Delphi methods will he lp in assessing the market requirement and developing strategies accordingly. Finally, the company should adopt a clear communication model which would help the employees to understand the importance of work ties over cultural ties and also provide clear instruction process. After assessing the current scenario in Myanmar it is advisable for CIC to opt for subcontracting techniques (WiseGeek, 2011).The subcontracting technique is a type of job contract, which will help in outsourcing certain type of work to other companies (WiseGeek, 2011).

Air Pollution Essay Example | Topics and Well Written Essays - 750 words

Air Pollution - Essay Example The high altitude trees in the Rocky Mountains feel the impact of the air pollution emitted in Beijing, China. To determining the most rational approach to controlling air pollution, the worldviews of Environmental Wisdom and Planetary Management can help decide who has responsibility for the air we breath and what are the benchmarks for quality. Both worldviews rely on the tenet that our resources are valuable and require constant attention to provide sustainability and quality of life. However, they differ greatly on their approach, philosophy, and degree of optimism in technology. The Environmental Wisdom worldview takes the stance that the human race is a part of nature and must show an equal respect for all plants and animals in the world. Environmental Wisdom believes technology and economics are limited and there must be a sustainable cooperation with the earth to be able to sustain our resources. The Planetary Management worldview believes that man is the dominant life form on Earth and humans have a right to exploit the Earth's resources to assure their well being. Planetary Management has a high degree of optimism in both technology and economics. ... A major air pollutant that has been at the center of controversy are the CO2 emissions that come from burning fossil fuels. Environmental Wisdom believes that the Earth's fragile ecosystem is threatened by global warming and there is a need to curtail the use of this energy source. It has recently been reported that rising global temperatures have been responsible for the spread of the Asian Hornet which is known to destroy the hives of honeybees (Allen). Loss of the pollination done by honeybees could result in a 26 percent reduction in the US's available food supply (Young). Environmental Wisdom sees the need to reduce CO2 emissions and protect the habitat of the honeybee. The CO2 that is emitted in Beijing has a direct effect on the quality of food in the US. While we may be able to live with a short supply of copper, Environmental Wisdom contends that there is no substitute for quality air. Planetary Management advocates would view the problem of CO2 emissions as a temporary problem that will be solved by science. The air could be cleansed of excessive CO2 with new scientific discoveries and an economic stimulus to develop the technique. In fact, researchers are already developing a method to strip our the CO2 from the polluted air, liquefy it, and bury it underground (Haszeldine). This would allow man to continue to deplete the fossil fuel resources and manage the polluting by-products of its use. Planetary management would have less concern for the complex eco-systems, such as honeybees, that may be threatened or eradicated by global warming. These would simply be further challenges to our technology and inventiveness. In conclusion, all the people on the earth

Organic Foods - Annotated Bibliography Example 1. Derk Jan Stobbelaar, Gerda Casimir, Josine Borghuis, Inge Marks, Laurens Meijer & Simone Zebeda. (2008) Adolescent’s attitudes towards Organic food: A survey on 15 to 16 year old school children. International Journal of Consumer Studies. In this article the authors, have touched upon the need for aiming at organic policies keeping in mind the adolescents. As adolescents are going to be the consumers of tomorrow, the authors conducted a survey among school children in the ages of 15-16 years which tested their knowledge about organic food. The survey conducted among 700 students also examined their attitudes towards organic food, whether they bought organic food and their influence upon their parents to buy the same. The findings of the survey revealed that the adolescent children had a positive attitude towards organic food. Even though their attitude was positive, they had little knowledge about it and were not too willing to buy it. The authors suggested that the campaigns aimed at the target group should be designed, keeping in mind their preferences and ethical values. 2. Sylvette Monier et al. (2009) Organic Food Consumption Patterns. Journal of Agricultural and Food Industrial Organization. The authors Monier et al., conducted a research on two different issues relating to the consumption of organic food in France. Since it was aimed to increase the consumption of organic food the issue that was first researched was whether the choice for organic food was permanent or not.

In Europe after the second world war several cities approved price Essay

In Europe after the second world war several cities approved price ceilings on rental accommodation - Essay Example The protest of people for controlling price is understandable. Even though price control is understandable but still the government may be able to protect only some of the consumers while imposing negative impact of price control on others. However the aim of the government is to protect the group that usually gets pressed hard because of inflation. Thus charging high interest on different loans is to protect people who are forced to borrow out of desperation. Similarly the maximum price of eatables, such as bread, is to protect poor ones who completely depend on it for their survival and the rent control is for protecting the landlords at times when the demand for the apartments exceed the supply (McEachern, 2012). The New York State legislators are seen defending the Protection Act of War Emergency Tenant in order to cater the housing shortage related to war. The war that has been addressed in this law is not the Vietnam War or the war of Iraq but it is the World War II, which is considered to be the starting of rent control issues in America. Although war has not much to do with the shortage of apartments, as the shortage are more likely to occur due to rent control; which is considered to be the supposed solution for making accommodation readily available. Gotham is the only city of America which embraces rent control; however many other cities have surrendered to the blarney of this legislative fix (Christ, 2009). Like all the other mandated price control of the government, rent control is also considered to be a law related to the fixation of maximum price or â€Å"rent ceiling†, which explains that what exactly the landlords must charge from the tenants. In order to make the rent ceiling work, the rent must be placed below the rate that would be prevailed otherwise. For example, an enactment prohibiting landlords from exceeding the apartment rent from $100,000 per month would have not been

Terrorist Behavior Essay Example for Free

Terrorist Behavior Essay After reading the article on â€Å"A Look at Terrorist Behavior† I found out some very interesting details on how they plan, prepare and also where they would strike. After reading the article I learned about approximately how close to a target a terrorist would likely live. A recent study shows that most terrorist lives closer to their target of choice. By being so close to their target they would learn and gather information quickly in aiding them to accomplish their mission. They would also end up studying a target for months or even years. According to analysis on terrorist residence to target of all groups around 44% of them live within 30 miles of their required target. There are four types of terrorist groups international, right wing, environmental and left wing groups. However since there are different types of terrorist groups they are different. For example international terrorist mostly lived closer to their targets, when right wing terrorist live in rural areas and would selecting targets in nearby cities. Terrorist mostly use a lot of surveillance and intelligence to help them aide in founding for their group. Most terrorist would stay close to their homes because of new immigration status and sometimes the lack of transportation. Terrorist living in urban areas are most likely would avoid attention. They are known as â€Å"lone wolves† they would target locally much uncoordinated violence such as anti-abortion extremists. Among a single-issue terrorist 77% of preparatory acts usually occurred within 12 miles and 92% occurred within 28 miles of their target. There are about a half of environmental terrorist’s acts only three fifths of them live roughly about 30 miles of their target. 5% of environmental terrorist and 59% international terrorist prepared for their target within 30 miles. Terrorist also conduct robberies, burglaries and thefts further away about an average of 429 miles from their homes. Running Head: Terrorist Behavior. As for law enforcement the implications of finding out about the proximity and preparation and time of a terrorist attack are very significant. With the help of early intelligence this can help law enforcement a lot of time to stop terrorist before an attack. Such Intel will also help local officials to respond rapidly. Law enforcement official must understand that most terrorist act locally and it’s important to know how to conduct a proper investigation method to seek and help prevent terrorism and also arrest perpetrators. Having a local pattern can be more efficiently in patrolling of high-risk target areas and gather enough Intel on suspected terrorist actions. Law enforcement officials will continue to understand and learn the relationship and the locations of terrorists preparation activities and their target of choice will help boost the knowledge and should help officers prevent and respond quickly to a terrorist attacks. Another way for local police to successfully meet the challenges posed by terrorism would be a time-tested approach that emphasizes prevention must converge with new ones that focus on prediction. Local police must also add critical elements of speed, resources, and numbers to any situation when necessary. They must be able to deploy rapidly and can quickly get more forces if needed. Homeland security must be ready at all times for any terrorist acts and threats. Overall I think if our homeland security along with local police train more and learn how terrorist operates I think our country would be safe somehow from a terrorists attack.

The three demands of being a college student Essay Example for Free

The three demands of being a college student Essay Modern life offers great opportunities for college graduates. That is why receiving college education is very important in today’s fast dynamic world. However, studying in college puts a lot of responsibilities on the shoulders of students, because they have to experience an increased level of academic requirements and competition, which make them feel more responsible for their actions, achievements, progress and even failures. Since college environment is completely different than the one of high school, studying in college requires from the students to use more skills than they used in high school. Therefore, attending college is more demanding, because students need to learn how to manage their time, strengthen their reading skills, as well as improve their social skills. First of all, effective time management in college is very important for students to be successful. In high school, teachers try to be easy on students with the due dates of the assignments or with students’ being late for the classes. However, in college, teachers tend to set everything in stone. For example, all college students are required to submit their assignments and projects on time. They also have to be in their classes on time whenever exams are held. Not following these guidelines can cause a lot of problems for the students who want to receive high final ratings. Moreover, college requires the students to complete full taken credits successfully. So, for students to do well in college, it is necessary to know how to manage their time properly. Another important demand of being a college student is developing strong reading skills. In college, the majority of classes require students to read in order to understand the lectures throughout the semester. For example, my History 10 class fully depends on reading the textbook in order to understand the lectures given in the class. Also, college teachers require their students to read some specific textbooks, so the students can participate in the graded in-class discussions. That is why college students have to keep in mind that reading is one of the paramount necessities because it helps to achieve good academic success and a great number of their other personal goals. And, finally, most classes in college require students to work in groups for setting a competition among classmates and making the students to receive better results. In order to perform a group work students need to know how to socialize and establish good personal connections with the classmates. Strong social skills help college students to participate in various team projects and receive good reward from such work. Besides, when a student knows how to communicate with his classmates and to convince them of his point of view, he will have a great opportunity to feel more comfortable in social environment of the college. This means that socializing also helps students to be successful and demonstrate great academic performance in college. Therefore, the demands of being a college student are quite different than usual demands for high school students. In college, every student has to learn time management, reading skills, and social skills because those abilities are very helpful for every student to get through the last stage of his or her academic life. Nevertheless, college students should keep in mind that their experience and knowledge received in high school are crucial and very important, because everything they learned during their high school times will help them a lot to progress, advance, get good grades, win a good reputation, and make their years of studying in college bright and interesting.

Should Offshore Oil Drilling Be Allowed Environmental Sciences Essay

Should Offshore Oil Drilling Be Allowed Environmental Sciences Essay The time has come to put a stop to offshore drilling. Finding renewable resources and alternative energy can help put an end to drilling into our ocean floors and help us become an independent nation. There are an abundance of technological capabilities available in our world today and these should be pursued in depth to not only solve the current crisis, but also to ensure that the same tragedy does not occur again. The technology is here and the time is now. Renewable resources are resources that can be continually reproduced over a short period of time (Renewable Resources). Here are a few examples: wind energy generates electricity by using the wind, wave energy produces electricity by using the power of ocean waves, and bio energy uses biomass (plant materials, landfill or animal waste) to produce heat or electricity. One example of barriers that prevent us from obtaining renewable energy is utility rate structure. Unfavorable utility rate structures have perennially been a barrier to increased deployment of renewable energy technologies. Unless carefully monitored to encourage the development of distributed generation, rate structures can increase the cost of renewable energy (e.g., through stand-by rates, lack of net metering) or completely disallow connection to the electrical grid (EPA). Another difficulty that prevents us from attaining renewable energy is the complexity in obtaining environmental permits for major industrial facilities. Transmission is another concern that prevents us from having renewable resources available. Many renewable resources are located in remote areas that lack ready or cost effective access to allow for transmission to the user. The building of the Alaskan Pipeline cost eight billion dollars for eight hundred miles of pipeline (Thinkquest). It would be much more cost effective to drill for this oil in the ocean where the cost to transport the resource to the coastline and ultimately to the end user will be far less costly. Each year, the annual cost just to run this pipeline is roughly two hundred and ten billion dollars. In addition, the start-up costs alone are so immense that they are essentially unavailable. States that have not established clear utility regulations that enable investments in transmission to be reimbursable or coordinated planning and permitting processes, slow the development of utility scale renewable projects in their territory (EPA). The only problem with things like biofuels and solar energy is, ironically, they still need oil to get up and running. Solar panels require the use of oil during its production, and ethanol has to be processed using the very substance it is supposed to replace (Heigler). The benefits of offshore drilling certainly outweigh the dangers of extracting oil from deep-water drilling off the coast of the United States. Specifically, there are a couple of reasons that support our continued practice of offshore oil drilling. First, it will create jobs that are essential for our country and the economy to thrive as an independent nation. Allowing offshore drilling will also make us less dependent on foreign oil. Yes, our nation is addicted to oil. Another reason to drill is that it provides us with natural gas, alternative fuel and gas and oil that fuel our aircrafts, ships and homes. However, now we are in the twenty-first century and it is time to put our advanced technology to good use. Continuing to drill will create jobs; nevertheless, using alternative energy sources will also create jobs and help preserve our planet at the same time. Offshore drilling creates countless jobs that help sustain our economy. Our stable economy is achieved through a consistent and stable work force that allows our citizens to work and pay for their needs. This economic system of checks and balances perpetuates a stable economy for us all. Offshore drilling alone accounts for such a great number of these jobs; a system that relies on the combined efforts of such a vast array of occupational titles that the number of total jobs currently available is four-thousand, four hundred eleven in the United States alone (Careers). Some examples of jobs that are unique to this field of work are; Drilling Supervisor Jobs, Senior Drilling Engineer, Drilling Business Development Manager, and Field/Mechanical and Equipment Engineers (Careers). These occupations are so unique to this field of work that a myriad of trained oil workers have virtually no useful skill that can be easily transferred to another job. If the oil drilling workers lose their jobs, many would have to be retrained into another line of work since there are no alternative locations to move to for oil drilling work. One of the largest companies currently pursuing the development of oil and gas resources is British Petroleum. This company began as Anglo Persian Oil in the year 1909. In 1954, it became British Petroleum. This companys reach is worldwide. Its revenue in the United States is approximately two hundred forty-six billion, with ninety-two thousand employees (BP). Our reliance on the natural resource of oil and continuously increasing demand for it has driven us to seek out new locations to tap intothe coastal waters that surround the United States. This remarkable feat is one that must be mastered and performed without flaw. British Petroleum has successfully drilled for oil off the coastal waters of the United States for more than three decades, yet their recent tragedy is one that poses such a grave danger to our environment that the result may be irreversible damage to our entire ecosystem. It is not a good proposition to boycott British Petroleum because if that happens, the oil company will not be able to pay claims to the people who have lost everything in the Gulf of Mexico. A boycott would also affect the small business owners who own these stations and further cripple their livelihoods. The only connection these business owners have with British Petroleum is the contract to buy gasoline. To win back customers, theyd like British Petroleums help in reducing the price at the pump (Nola). The disaster in the Gulf of Mexico has damaged the ecosystem, an undetermined amount of land, ocean, animal species and plant life. The production of life that begins in the marshes is now laden with massive amounts of oil. The cycle of life that begins here will be suffocated by the oil and therefore cease to exist. The natural lifecycle of the many animals that reproduce in this region is greatly affected. Innumerable animal species are returning to the Gulf region to breed among the damaging plumes of oil that saturate this once vibrant ecological labyrinth. The newborn offspring will be immediately subject to the hazards of the oil-filled environment and incapable of escaping from it. The food needed to sustain the new life in this region will come from the oil tainted environment and be directly fed to the newborns. The oil that is then ingested can cause poisoning of wildlife. Animals on every level of the food chain are affected as each one feeds on another to continue the cycle of life. The animals that reside in the Gulf of Mexico, life-long inhabitants, each contribute to an immense ecosystem that make up the complex weave of life that, until now has thrived uninterrupted. Thus far, hundreds dead birds, sea turtles, dolphins, fish and starfish have washed up onto the shore. The collective damage to the animal life in this region may not be completely realized for many years. This disaster will permanently alter the lives of countless animals. The newborn animals are immediately subject to exposure of the oil-filled environment and incapable from escaping from it. The direct physical effects on the animals exposed to the oil are lethal. Exposure to the oil can cause animals to suffer impairment of their red blood cells. Further, damage to or suppression of marine mammals immune system can cause bacterial or fungal infections. Oil can also deteriorate the thermal insulation of the animals skin, thus damaging their reproductive system. Injury to the airway or lungs of marine mammals can cause congestion, pneumonia, emphysema, or death by breathing in droplets of oil, fumes or gas. The clean-up has been slow and it appears there is twice as much leakage as what can be cleaned up. British Petroleum is still trying to burn off the oil on the surface of the ocean which is then polluting the air. At this point, every regulatory authority and British Petroleum is not moving fast enough to clean this mess up. They have the technology and the dollars to do this. There is not much progress being made and it has been almost three months. Tar patties from the Gulf oil spill started washing ashore on Front Beach around noon on Monday, a day after the oil first made landfall on the Mississippi mainland in Jackson County (Al.com). Twenty billion will only make a dent in helping these residents regain control of their lives. This tragedy is a true example of what can happen when big business goes well beyond the unwarranted point of trying to cut costs. Their actions repeatedly support this statement. They are not paying the fishermen who are no longer able to work to support their families. They are not paying for mass groups of workers to be trained to assist with clean up, nor providing the few who have received the training briefing the proper respirators to wear. The jobs that were plentiful for residents along the Gulf of Mexico have all been lost recently due to the Federal Governments moratorium on all oil drilling, which was implemented in response to the Deep Water Horizon oil rig. Offshore drilling is one of the biggest sources of financial revenue for the population in and around this geographical region. Residents who have grown to rely exclusively on their steady income from oil drilling are rapidly experiencing such financial loss that their lives have become filled with financial uncertainty and their expectations for achieving employment remains in peril. From the highest paid engineer to the lowest man on the rig, the loss of countless jobs that once were plentiful when the oil was being actively drilled will have a negative impact on their lives as well as our economy. It will trickle down; the economy will get even worse, said Perry Clement, a local who serves as a deck hand on several fishing boats, and is struggling for incom e. Its the delicate balance we have, with the oil and the fishing (Marketwatch). This ban proposed to put a six month seize on all deep water oil drilling in the United States. This decision would stop any new permit approvals for deepwater drilling at more than thirty existing deepwater wells. In addition, the moratorium will further cripple the jobs for immeasurable other independent drillers, equipment makers, hardware stores, manufacturers, and transportation systems that provide direct and sustained support to the effort of drilling for oil. Even with a situation as grave as the Chernobyl accident, we did not halt the production of or rid the world of nuclear power. The governments decision to stop all drilling until we can find out the cause of the disaster and prevent further ones from occurring does not support our overall economy. Offshore drilling will always be a risk, but the nation must move forward and continue to make progress. Today, over eighty percent of world petroleum reserves are state-owned and controlled by countries that have the power to manipulate supply and price with impunity, this fact goes directly to the heart of energy security (Energy Independence). According to most forecasts, oil will remain the top global energy source for the next few decades, even with the ongoing development of natural gas, nuclear, and renewable resources. Today is day 70 of the Gulf of Mexico oil spill. The latest news is that a federal appeals court in New Orleans will hear the governments appeal of a ruling overturning the deepwater drilling ban in the Gulf of Mexico on July 8. The six-month moratorium was ordered in late May by the Barack Obamas administration after the Deepwater Horizon disaster. A group of offshore petroleum service companies sued, saying the moratorium would inflict long-term economic damage. A federal judge agreed with the companies and barred the government from enforcing the ban. British Petroleum and the Coast Guard sent oil-scooping skimming ships in the Gulf of Mexico back to shore because nasty weather is churning up rough seas and powerful winds. Although Tropical Storm Alex was projected to stay well away from the spill zone before possibly making landfall as a hurricane near the U.S.-Mexico border, its outer edges were causing problems out in the Gulf. Waves were as high as twelve feet Tuesday in some parts of the Gulf (AP). British Petroleum says it will give cash and other help to the owners, operators and suppliers of the gas stations around America that bear its name. They say they have been struggling because of boycotts prompted by the oil spill. John Kleine of the British Petroleum Amoco Marketers Association says outlets will get cash based on volume, with the rates being higher for outlets in the Gulf than for that elsewhere in the country (AP). They also will see reductions in credit card fees and get help with national advertising. While wildlife casualties are many, there were seventy-two pelicans released Tuesday, in Georgia and last week sixty-two pelicans were rehabilitated and released on the Texas coast. About fifty-thousand sea turtle eggs from beaches in the Florida Panhandle and Alabama will be dug up and moved to Floridas Atlantic Coast in hopes of keeping the hatchlings alive. Without this intervention, federal scientists believe, most, if not all, the hatchlings this year would be at high risk of encountering oil and dying. The Fish and Wildlife Service, National Marine Fisheries Service and Florida Fish and Wildlife Conservation Commission recommended that the nests be collected near the end of incubation and taken to Floridas Atlantic Coast for final incubation and release. Hatchlings begin emerging from nests in early to mid-July (Straub). The production of life that begins in the marshes is now encumbered with massive amounts of oil. The cycle of life that begins here will be suffocated by the oil and therefore halt. Damage has been done to coral reefs, sea grass, and mangrove habitats which are breeding areas of many fish and crustaceans. This unique ecosystem is also home to many smaller species such as mussels, crabs, oysters, shrimp and plankton. The direct physical effects on the animals exposed to the oil are lethal. Exposure to the oil can cause animals to suffer impairment of their red blood cells. Further, damage to or suppression of marine mammals immune system can cause bacterial or fungal infections. Oil can also deteriorate the thermal insulation of the animals skin, thus damaging their reproductive system. Injury to the airway or lungs of marine mammals can cause congestion, pneumonia, emphysema, or death by breathing in droplets of oil, fumes or gas. Increasing demands for oil continue to multiply by the day. Extracting oil resources from land have proven costly and inappropriate due to the location and availability. Continued independence of our nation will be achieved through a decline in our reliance on foreign countries which will ultimately create jobs that sustain our economic future. British Petroleum has successfully drilled for oil off the coastal waters of the United States for more than three decades, yet their recent tragedy is one that poses such a grave danger to our environment that the result may be irreversible damage to our entire ecosystem. British Petroleums CEO been transparent in revealing his true feelings about this disaster on numerous occasions. Recently, he stated that we care about the small people. Are the small people he refers to the entrepreneurs who are independently wealthy because they work in harmony with nature, providing a precious food commodity to thousands without ever impeding the natural cycle of life for over a century? He also stated that nobody wants this thing to be over with more than him because he wants his life back. I am certain that the eleven men that died on his oil rig want their lives back.

Christmas Essay -- Narrative Essays, Descriptive Writing

A few days before Christmas, Oxford street is swarming with last minute shoppers, laden with parcels and bags. Christmas is the highlight for many people, especially little childen, from as tall as your ankle to as tall as your knee. Small todlers were moaning and disappearing into the clothes racks like magicians disappearing in a puff of smoke entertaining the gullible audiences. Families and friends gradually emerge from clogged buses and congested trains, tired, exhausted and hungry even at this very early stage, as if they had spent the whole night awake, like a distressed parent waiting for their child to arrive home from a party but has still not arrived, two hours past their curfew. Oxford street is the main high street of the whole of England. It flocks many tourists, as though it has a force or power, just like opposite ends of a magnet attract one another.

Oxford street contains a lot of various shop which other high streets have, plus some extra. It is as if Oxford street encloses a immeasurable proportion of England as it has a great deal of stores; some immense while some petite.

It is one colossal, huge, extensive, perpendicular road with a range of exits... ...ng for breath. As I walk through 'MK1', I can undoubtedly see that many shoppers were haggling over the price of purchases. Then someone barges into me and I very nearly fall over with the force of it. After I recover from my sudden fall, I widen my horizon and gaze upon particular groups of people. I get attracted to look at the people with loud voices. The brightness of the light decreases as the clouds begin to fasten together together structuring one massive cloud. It began to snow. The cold was beating on me. I felt the cold reaching my body even with wearing a thick layer of wool covered by a fur coat. It was as though I was wrapped with a sheep, which had never had its fur, trimmed. The bitter air smacks my face as I walk, without any energy and worn out, forwards towards the end of the road to relaxation.

Cigarette Smoking is a Costly and Deadly Habit! Essay -- Argumentative

Abstract Cigarette smoking is the greatest preventable cause of disease and premature death in the United States. Secondhand smoke causes numerous lung cancer deaths annually. Measures have been taken in both workplaces and public places to limit exposure to secondhand smoke. The economic cost of smokers to society is phenomenal- it includes monetary costs, lost workdays and shortened work lives. Many states are establishing and maintaining comprehensive tobacco-control programs to reduce tobacco use. They provide education to our youth to prevent them from ever starting and smoking cessation programs for individuals that currently wish to stop smoking. Education and support are known ways to eventually prevent smoking in the future. Efforts to increase the public perception of the harmful effects of tobacco must utilize a comprehensive approach that affects policy development, education strategies and health care systems. Smoking is becoming more and more unfashionable as time goes on. There are many studies conducted showing that secondhand smoke is a health hazard to both the smoker and anyone that relies on the same air supply, not to mention the unpleasantness and discomfort it causes those that do not smoke. The Environmental Protection Agency reports that it is estimated that secondhand smoke that emerges from exhaling and burning cigarettes causes approximately 3,000 lung cancer deaths and 37,000 heart disease deaths in nonsmokers each year. (Nolo, 2002). According to a 1998 Gallop poll, 94% of Americans, including both smokers and nonsmokers, agree that companies should either ban or restrict smoking to properly ventilated areas. Another Gallop poll indicates that 95% of nonsmokers, and 69% of smokers, t hink California's ban on smoking in almost all workplaces is positive. Some companies are now refusing to hire anyone who admits to smoking on a job application because of higher healthcare insurance, absenteeism, unemployment insurance and workers' compensation insurance associated with these individuals. (Nolo, 2002). Those that do not smoke feel it is an infringement of what they consider to be a reasonable right not to have to breath other people’s cigarette smoke while at work. During the 1970’s the dangers of secondhand smoke were beginning to amass and a movement for nonsmokers emerged. When it was proven that secondhand smoke was ... ...ity and Mortality Weekly Report, Guidelines for School Health Programs to Prevent Tobacco Use and Addiction, (Vol. 43). No. RR-2. Lee, P.R. (1994).

Comparison between The Tell-tale Heart Essay

The Tell-Tale Heart was written by Edgar Allan Poe in 1843. Famous for his scary novels Poe’s most famous work was the short story, The Tell-Tale Heart which depicts an anonymous narrator as he carries out his plan to murder a helpless old man. Misery was written by Stephen King in 1987 and it follows a similar theme of horror/thriller with similar characters in similar positions. King tells the story of a renowned author as he gets captured and tortured by a woman. Both of these stories use different techniques through their plot, language and punctuation but they have much the same effect on the reader. In both stories, one of the underlying techniques for building up suspense is hidden inside a well thought out and structured plot. In Misery, the narrative switches back and forth between Paul the author, and his kidnapper, who is known only as Annie. This creates the main source of suspense in the story building it up by showing where each character is, what they’re doing and how close they’re getting to each other. What adds to this suspense is the effect of hearing Paul’s thoughts directly. Even though the extract is written in third person, a fraction of the text is written in italics and it represents Paul’s thoughts. The writer does this for several reasons. To show things from Paul’s point of view and what he is thinking at the time in more detail , but also to underline how worried and panicked he is as things start to go wrong. By hearing Paul’s thoughts directly the reader gets to understand how fearful Paul is of getting caught. Also concealed between the lines of the plot is the way the writer stresses the high stakes of what Paul was doing and what will happen to him if he’s caught. Right at the beginning of the extract, Paul compares what is happening to him, to his past childhood experience. Through this comparison, the writer introduces the possible idea of Paul getting caught and what will happen to him if he is. The flashback takes the reader back to when Paul had been twelve and decided to try some of his mother’s cigarettes. As the room filled with smoke, his mum returned in search for her forgotten purse. We are not told about what his mother did to him when she caught him, but you can guess from the words â€Å"It will be more than a spanking this time† that it was going to be bad. This tells us that if he is caught by Annie in present day he would have to face terrible consequences. Paul compares these to situations because in both he’s attempting something and trying not to get caught. In the flashback he does get caught, giving a sense of foreboding to the rest of the story, making the reader think he might get caught again. The high stakes are also shown throughout the extract in Paul’s actions and thoughts. His desperation in his attempts to get back into the room and lock the door and his attention to detail show how scared he is of getting caught, because of what he thinks will happen to him if he is. â€Å"Oh Jesus Christ, did you chip the paint, did you leave a track†. His thoughts also scream fear and anxiety in the way punctuation like question marks, exclamation marks and pauses are used. â€Å"did she hear that? She must have must have heard that! † These things are used very effectively as Paul stumbles upon problem upon problem as he attempts to return to the living room after failing to escape from his prison. He must leave everything the way it was to avoid suspicion from Annie, his kidnapper. However his luck doesn’t seem to be doing him any favours whilst Annie pulls up the driveway. His first problem was getting into the living room; the wheelchair was a very tight fit. On his first go he crashed into the side, â€Å"The wheelchair thumped against the right side of the doorway and bounced back a little†. His reaction to this was one of great terror and panic, â€Å"Did you chip the pain? His mind screamed at him†. On his second try he got jammed in the doorway and wouldn’t budge. The amount of effort he put in getting through shows the reader how scared he was of the cost of getting caught. â€Å"The muscles in his arms quivering like overturned violin strings†. The other problem that he encounters is made clear to the reader, as Paul tries to close the door of living room. The door must be closed and locked in order to leave everything the way it was before Annie left it and avoid suspicion. However whilst pushing the lock back with his thumb he meets an obstruction. Through panicked deduction he realizes the bobby pin he had originally used to unlock the door was stuck in the keyhole, stopping the lock from going back inside. These events contribute greatly to the suspense of the extract by giving Paul more chance of getting caught and keeping the story thrilling and fast-paced. In terms of pace I think that in Misery, as Paul encounters several problems on his return to the room, the story is more fast-paced and exciting than The Tell-Tale Heart. In comparison with Misery, The Tell-Tale Heart is extremely slow and unhurried because as it is first person the narrator is describing everything in full detail and all his thoughts at the time. Plus most of the murder involved waiting. At the end of the extract Paul overcomes all his problems but as he sat in his wheelchair awaiting the untimely arrival of Annie, he looks down and realises that the box of Novrils is still in his lap. â€Å"The box of Novrils was still in his lap†. This final sentence in its simplistic form puts an end to Paul’s series of unfortunate events in a great climax of suspense. The sentence is short and straightforward, leaving the reader to work out what will happen for themselves. There was no way Paul could do anything with the box without being seen because Annie was just on the other side of the living room door. If she found him with the Novrils (which were fictional painkillers) she would be able to guess what he was doing whilst she was out and he would have to pay the dire consequences of his actions. From the extract, the way Paul was reacting to every detail of the room, you would fear the worst for his life. The sentence finishes the extract with an ominous feeling for what will happen to Paul when discovered, leaving the story with a suspenseful cliff-hanger. In The Tell-Tale Heart, the way the plot builds up tension lies solely with the narrator and the way he recounts the story of how he killed an old man. The narrator starts the story by trying to convince and persuade the reader that he is indeed sane and not mad. This in itself is mysterious; what had he done that needed persuasion on others behalf to credit as sane. The narrator then introduces the idea of a murder by first establishing the motive behind the crime. The narrator states that he killed the old man (the victim) whom he loved, on the basis that he had and eye that resembled that of a vulture. â€Å"I think it was his eye! Yes it was this! One of his eyes resembled that of a vulture-a pale blue eye with a film over it† The motive is ridiculous and in no way should it inspire an act of murder. By first introducing the idea of a murder through the murderer’s motive, the writer allows the reader to make up their opinion on the sanity of the narrator at the beginning of the story whilst enticing the reader’s imagination leaving them wondering what else this madman will do. So already the reader would have a set opinion on the narrator, and the narrator’s behaviour throughout the rest of the short story would do nothing but solidify their suspicions of a troubled individual who is mentally ill. This is not only because he/she is constantly trying to prove their genius thinking behind the murder, but also because they believe that this genius and cunning must surely grant them their sanity. â€Å"Would a madman have been as wise as this? † At the end of the story the narrator (lulled into a false sense of security by his soon to be short-lived success) permits the entry of several policeman into the very room where he had committed the murder, after they came knocking to investigate a mysterious noise heard by one of the neighbours. Not only does he let them sit in the room, but also on the very floorboards where the cut up parts of the dead body lay hidden beneath. Though this just maybe a sign of over-confidence, it is bordering on madness and another reason for the reader to doubt the judgment of the narrator. If all this strange behaviour isn’t enough to chill the reader, then the murderer hallucinating should be. His guilty conscious gets the better of him and he thinks he can hear the imaginary beating of the stopped heart of the dead old man. The narrator succumbs to the noise by confessing to the clueless police sitting in front of him, that he had killed the old man who had lived here. â€Å"†Villains! â€Å"I shrieked, â€Å"Dissemble me no more! I admit the deed! -tear up the planks! -here, here! – it is the beating of his hideous heart! â€Å"† The narrator’s insane behaviour throughout the story adds to the horror atmosphere of the text. As a final sentence, I would say that Misery ended better than The Tell-Tale Heart in terms of suspense, because it leaves more unexplained questions in reader’s mind. This is probably because Misery is an extract and still in the middle of its story, and The Tell-Tale Heart finishes with its last line. As an ending I do believe that the final sentence of The Tell-Tale Heart is satisfying as it gives the reader the bare minimum information for the reader to deduce what happens to the murderer after he confesses instead of just saying that he was arrested and went to prison. After analysing both plots, overall I think that the plot of the Misery extract builds up tension better than The Tell-Tale Heart solely on the belief that it is it’s faster-paced therefore much more exciting. The effect of the chosen narrative for The Tell Tale Heart, which is first person and from the narrator’s point of view, lets the reader into his/her mind and see their motives and thinking behind an atrocious crime. First person is perfect for The Tell Tale Heart because looking into the murderer’s mind is exactly what the reader needs to get a proper grasp of the plot. The disadvantages however, are you do not get to find out the gender of the murder because it’s all â€Å"I did this† and â€Å"I did that†. Also you don’t find out what the old man is feeling or what he is thinking. For Misery however third person is used and that also suits the story quite well. This way you’re aware of both Paul and Annie’s actions at the same time. If it was first person and from Paul’s point of view, since Paul couldn’t have known exactly where Annie was and what she was doing and how close she was, the reader would be clueless and the main way the plot builds up tension would be gone. If it was from Paul’s point of view, the focus of the narrative will no longer switch between Paul and Annie, therefore eliminating one of the ways the plot creates a gripping atmosphere and seriously lowering the suspense levels. The disadvantages of third person are made up for by being able to see Paul’s thoughts directly. Other than the plot, language is the main source of suspense used to create the atmosphere of the two texts. In Misery, the writer has chosen to use individually effective words that remind the reader of death whilst describing something that is completely unrelated. Phrases such as â€Å"stopped dead† and â€Å"inside the guts of the lock† and â€Å"Wasn’t it enough she killed the phone? † In all these occasions, the writer could’ve used simple, non-death associated words, but instead he used the words â€Å"dead†, â€Å"guts† and â€Å"killed†. All these words inspire the thought of death in the reader’s brain, and although it is not directly mentioned it subconsciously arouses the idea of Paul’s death in the reader’s mind. This adds to the overall horror and suspense of the extract. In The Tell-Tale Heart individual words are also used to set the mood of the text but in a different way. Instead of death-connected words, the writer has used long and soft sounding words to slow the pace of the story and calm the mood. â€Å"I undid the lantern cautiously – oh, so cautiously – cautiously† The use of the word cautiously, which is a long and soothing word, slows the pace of the story down and set s a calm atmosphere. In terms of adding suspense to the text, I believe that Misery’s use of death-related words is more effective. In that sentence, the other thing that calms the mood is the use of repetition. As the narrator repeats the word â€Å"cautiously†, it emphasizes the fact the narrator was cautious and it shows the narrator’s arrogance in their actions. However repetition is used for other purposes throughout the short story. â€Å"It grew quicker and quicker, and louder and louder every instant . . . It grew louder I say, louder every moment† This phrase contains a lot of repetition as the narrator is trying to stress how quick and loud the beating heart was. The repetition also allows the writer to show how agitated the narrator is getting, because of the fact it was getting quicker and louder, but also because he thinks that the reader doesn’t believe him. A clear sign of insanity. In Misery repetition is used for similar reasons, but instead of agitation it’s to show the characters desperation, in phrases like â€Å"Caught! I’m caught! Please God, no God; don’t let her hurt me God† and â€Å"Come on . . . Come on . . . Come on†. In the first quote the repetition of the word â€Å"God† shows that he’s really desperate and has started to pray to God to help him. The second quote is similar as he is repeating the words â€Å"come on† as he gets more and more distressed. In misery what are also used to emphasize a point are superlatives like â€Å"in the grip of the greatest terror he had ever known†. This superlative highlights how bad the experience was for Paul. I believe that The Tell-Tale Heart’s use of repetition is more effective than Misery because not only does it build up suspense but also it shows signs of madness in the narrator’s behaviour which does not occur in Misery. This helps the plot on the whole build up tension. There is a great variety of long and short sentences in both stories. In both pieces of text short sentences are used to slow the pace of the text down. In the Tell Tale Heart it shows that the narrator is calm and unrushed. â€Å"But even yet I refrained and kept the lantern still. I scarcely breathed. I held the lantern motionless†. However, in misery short sentences are used to emphasize what’s happening in the sentence. â€Å"It was her†. This sentence just highlights the fact that it was Annie pulling up the driveway, and it makes the reader think about the consequences of these events. Although both are successful in creating suspense, I believe that Misery is more effective. Long sentences are usually used to keep the story going and build up the suspense. In Misery however, long sentences also show that Paul is panicked and rushed. â€Å"He sat in his chair, eyes half -closed, hoping madly that he had gotten the chair back where it had been(or at least close enough to it so she wouldn’t notice), hoping that she would take his drenched face and quivering body simply as reactions to missing his medication, hoping most of all that he hadn’t left a track†. This humungous sentence shows how worried Paul is of getting caught and it’s a great way to build the suspense because it allows no pauses. In The Tell-Tale Heart, long sentences aren’t used as effectively to build up suspense. In both pieces of text, there is a lot of punctuation used effectively to add horror and tension. The Tell-Tale Heart is first person and from the narrator’s point of view, so exclamation marks and capitals are used for his thoughts when he is angry and or shocked. â€Å"They heard! -they suspected! -they KNEW! -they were making a mockery of his horror! † The exclamation marks and capitals are emphasizing his thoughts, showing his rage and disbelief, whilst the dashes allow no pause and add suspense as he moves from one revelation to another. In other occasions, exclamations are used to show the narrator’s surprise and wonder at his own brilliance and ingenuity. â€Å"Oh, you would have laughed to see how cunningly I thrust it in! † The Misery extract however, contained only a couple of exclamations, used only to show that Annie was shouting to Paul in the living room so they were less effective than ones in The Tell Tale Heart. In The Tell-Tale Heart, because the narrator is recounting a story, it is almost as if he is having a conversation with the reader. At the beginning of the story, the narrator begins by asking numerous questions on whether or not the reader believed he was mad or not. â€Å"How then am I mad? † The effect of these questions and question marks makes the reader feel as if he had contradicted the narrator in some way and the narrator was having an argument with them. This is a good way to show the madness of the narrator from right at the start of the story. Question marks are also used in Misery however for different reasons. Phrases such as â€Å"did you chip the paint? † and â€Å"did you leave a track? † are used as another way to show Paul’s desperation but also to show his own uncertainty as he starts to panic. For these reasons I believe the use of question marks is better in Misery than in The Tell-Tale Heart. Another aspect of the punctuation in Misery is the use of pauses. â€Å"Come on . . . come on . . . come on† and â€Å"Never . . . never in time . . . She’ll hear† are two good examples of where the writer has used pauses to give a sense of desperation and anxiety to Paul’s thoughts. To conclude this essay, I would have to say that the extract from Misery by Stephen King is more effective than The Tell-Tale Heart in the way it creates an atmosphere of horror and suspense. It does this by using and expert blend of individually effectual words, well structured plot, effective narrative, well thought out and carefully placed punctuation, and a wide range of long and short sentences. Although The Tell Tale Heart does contain most of the techniques stated above, one thing I think Misery does better, and what makes it the better piece of text, is hidden inside its suspenseful plot line where Paul is constantly in a state of desperation and anxiety and in almost immediate danger. This I think is lacking in The Tell-Tale Heart, the sense of immediate danger, and is what makes the extract from Misery the perfect horror/suspense text.

Due to their efficiency, compactness, reliability and relatively low capital cost 81% of new electric power demand will be met by industrial gas turbines. Gas turbines must meet very strict NOx CO and CO2 regulations. (GL Juste 2006). As the popularity of gas turbines and combined heat and power generation plants increases research has turned to cheaper and more environmentally friendly fuels for gas turbines.Methane C2H4 is the main fossil fuel used in gas turbines today but with increased regulations on carbon emissions combined with the increasing cost of fossil fuels, research is turning to alternative fuels which may power gas turbines into the future. This literature review explores potential liquid and gas alternative fuels for industrial gas turbines along with some of the latest research in the area and some examples of the successful industrial applications. 2. IntroductionThe increasing cost of fossil fuels, the fact that they are a finite resource and the environmental effects of their combustion means that research into alternative fuels is one of the largest and most varied areas of scientific investigation in progress today. As with all scientific research, some will be successful and form the basis of future energy production and some will be either too inefficient or impractical to be implemented in industry. It is interesting to note that some of the methods which seemed impractical even 10 years ago are now being introduced owing to the increasing cost of fossil fuels.Fuels derived from biomass and gasification of sewage sludge and municipal waste and some methods of hydrogen fuel production appear to hold the most promise. â€Å"Different global energy scenario studies indicate that in India biomass may contribute much more: up to 30% of the energy supply b y 2100† (K. K. Gupta et al 2010) Gas turbines and combined heat and power (CHP) systems are at the forefront of future European strategies on energy production with current efficiencies for combined cycle facilities above 60%. â€Å"The main CHP targets are the reduction of the overall costs and the development of above 40 kW biomass-fired systems†¦..Gas turbines enjoy certain merits relative to steam turbines and diesel engines. They have high grade waste heat, lower weight per unit power, dual fuel capability, low maintenance cost, low vibration levels, low capital cost, compact size, short delivery time, high flexibility and reliability, fast starting time, lower manpower, and have better environmental performance. † (P. A. Pilavachi et al 2000) This project focuses on alternative fuels as applied to industrial gas turbines owing to their projected increase in popularity in the short to medium term at least. 3. Hydrogen 3. 1Production 3. 1. Steam Reforming of Hy drocarbons The bulk of hydrogen fuel production is currently via steam reforming of natural gas this process involves the reaction of natural gas or liquid hydrocarbons with high temperature steam to produce varying amounts of CO and H2. Steam reforming of hydrocarbons does not eliminate CO2 but it greatly reduces the amount which is discharged into the atmosphere. Steam reforming of hydrocarbons is an efficient way of reducing CO2 emissions. In addition to the H2 produced during gasification a low temperature gas shift reaction with the remaining carbon monoxide can produce further H2.The process of steam reforming natural gas along with the gas shift reaction are governed by the chemical equations below. (K. K. Gupta et al 2010) Steam Reforming: CH4 + H2O – CO + 3H2 ? H = +251 kJ/mol Gas Shift: CO + H2O – CO2 +H2 ? H= -42 kJ/mol (K. K. Gupta et al 2010) The release of CO2 can be completely eliminated in a large plant where the CO2 is captured and injected into an oil or gas reservoir. It is currently disputed between scientists whether or not the production of H2 in this way releases more CO2 than directly burning fossil fuels. 3. 1. 2Water SplittingThere is currently a lot of research concerning the splitting of water to produce H2. This method is yet to find industrial application as it takes a lot of energy to split water and the only sustainable method is the use of renewable technologies to provide the energy. The hydrogen is more likely to be used as a storage medium when the power generated by renewable technologies is not required. An example of this would be the storage of power from a wind turbine during the day. There is a lot of very interesting research into water-splitting with many methods being explored simultaneously.Thermo chemical water splitting using solar power is an interesting option. Direct thermal water splitting is impractical due to the energy requirements to heat the water to 25000K. But if the water is reacted with metal oxides and redox materials it can be achieved at a much lower temperature. The oxygen and hydrogen are released at different stages eliminating the need for separation. This process can be conducted in a cycle that produces H2 more efficiently from solar radiation. 3. 1. 3Gasification of Waste & Biomass to produce syngasA Practical Example of waste to energy conversion is the Pyromex waste to energy facility in Germany. The Pyromex system is currently being used successfully to gasify industrial waste in a purpose built plant in Munich Germany. Due to the fact there are no gaseous emissions from the system there is no need for the construction of smoke stacks and the system is considered separate to incineration by EU authorities. Emissions from the plant are in the form of solid sand like dry waste. The waste composition is tabulated below and shows how far below allowable limits the process is.The raw material in the process is otherwise unrecyclable waste products and the system can treat sewage sludge, plastics, fly ash from power plants and various other waste products. The system has the potential to be a major contributor to the Hydrogen Economy. The prototype plant working on a throughput of 25 ton/day had the potential to produce approximately 2150 kWh by a combined heat to electricity and syngas engine generator system. If used in combination with an industrial gas turbine there is no doubt that owing to the greater efficiency this power output could be improved.Fig. 1 – Exhaust gas emissions (Pyromex ®) 3. 1. 4The process The material to be gasified is introduced into the slowly turning reactor through a two stage tank system. With this setup an oxygen free environment can be ensured inside the reactor pipe, where the conversion of the organics to syngas takes place at over 1000 °C. The produced gas is then cleaned with a simple acid and an alkaline scrubber. Even though the temperatures within the reactor are far above 1000 °C, the surface remains cool enough to be touched by hand.The PYROMEX gasification is a closed circuit process and therefore no emissions are released into the environment. The process flow chart below gives a better understanding of the workings of the plant. This process can be easily scaled. And there are numerous plants completed and in the process of construction in Germany and the U. S. Fig. 2 – Gasification process of producing syngas from waste & biomass (Pyromex ®) 3. 1. 5Application to industrial gas turbines Once the hydrogen has been produced it can be mixed with carbon monoxide which can also be produced efficiently using solar power.This syngas can be used in an Industrial gas turbine with some modifications to the fuel nozzle system and careful control of the fuel air ratio to produce electricity. In the case of liquid fuel turbines the hydrogen can be converted to various hydrocarbons using the Fischer-Tropsch process. The use of hydrogen in a gas turbine is a r elatively new concept with the use of high hydrogen content syngas becoming an attractive area for research. Unfortunately the use of hydrogen rich gas in a conventional gas turbine involves some tweaks to the ystem. The natural gas lean-premixed combustors have to undergo some modifications if fed with hydrogen rich fuels due to the combined effect of hydrogen shorter auto-ignition delay and faster flame speed. (Paulo Gobbato et al 2010) One of the routes with the highest potential is the pre combustion route utilizing coal in an integrated gasification and combine cycle (IGCC). The challenge in utilizing hydrogen rich fuel is principally associated with its reduced auto-ignition delay time, which can be addressed in one of three approaches: 1.De-rating the engine – allowing the same mixing time by increasing the auto-ignition delay time through altering the characteristics of the vitiated air (i. e. the inlet temperature of the flow to the SEV). 2. Decreasing the reactivity of the fuel – i. e. by dilution with an inert gas. 3. Modifying the hardware – either to reduce the mixer residence time in line with the reduced auto ignition delay time or develop a concept which is less influenced by the reactivity of the fuel. (Nils Erland et al 2012) 4. Methanol 4. 1Abstract 5.When methanol is intended to be used as fuel for gas turbine, it is very important to enhance overall thermal efficiency of the gas turbine system, and to make it competitive with conventional oil or gas fuels. There are many ways to accomplish this. Combined cycle is not, however, a proper way, as this could also be applied to conventional fuel. Noting the unique characteristic of methanol, the steam reforming regenerative cycle was investigated by many institutions. In this scheme, wasted heat of the gas turbine exhaust gas is transferred to reformed gas.And it is recycled back to the gas turbine as a part of fuel, thus resulting in increased overall efficiency of the gas turbine. Thermal decomposition of methanol is also an endothermic reaction and may be applied to the regenerative cycle. In either case, however, only a part of the waste heat is recovered. Hence the hybrid system with combined cycle was proposed to achieve additional heat recovery. But this is a complex system. 4. 2Introduction 6. Methanol, also known as methyl alcohol, wood alcohol, wood naphtha or wood spirits, is a chemical with the formula CH3OH. . 8. Fig. 3 – Chemical formulation of Methanol 9. Methanol can be used as alternative fuel in gas turbine. Methanol is made from natural gas, coal, and biomass. This was one of the older alternative fuels. Like Ethanol, Methanol is very good for blending with gasoline to replace the harmful octane enhancers. The benefits of using Methanol are that it reduces emissions, which has a significant effect on bettering the environment. Methanol can easily be blended with gasoline. It also has a lower risk of flammability than normal g asoline.Another benefit of Methanol is that it is made from domestically renewable sources. Methanol can also be used to make the octane enhancer MTBE. Another huge possible benefit of Methanol is that it can be made into hydrogen. 10. 4. 3History 11. Methanol has been tested as a gas turbine fuel in the U. S. In 1974, a 12-hour test was conducted by Turbo Power and Marine in a 20 MW gas turbine at the Bayboro Station of Florida Power Corporation. The methanol was fired as a liquid. NOx emissions were 74% less than those from No. 2 Distillate, and CO emissions were comparable (Power 1979).In 1978 and 1979, EPRI and Southern California Edison Company sponsored a 523-hour test at SCE’s Ellwood Energy Support Facility, using one half of 52 4. 4Manufacturing Process 4. 4. 1 Production of methanol from synthesis gas 12. Carbon monoxide and hydrogen react over a catalyst to produce methanol. Today, the most widely used catalyst is a mixture of Cu (Copper), zinc oxide, and alumina f irst used by ICI in 1966. At 5–10 M Pa (50–100 atm) and 250  °C, it can catalyze the production of methanol from carbon monoxide and hydrogen with high selectivity (>99. 8%): 13. CO + 2 H2 > CH3OH†¦..It is worth noting that the production of synthesis gas from methane produces three moles of hydrogen gas for every mole of carbon monoxide, while the methanol synthesis consumes only two moles of hydrogen gas per mole of carbon monoxide. One way of dealing with the excess hydrogen is to inject carbon dioxide into the methanol synthesis reactor, where it, too, reacts to form methanol according to the equation: 14. CO2 + 3 H2 > CH3OH + H2O. 15. Some chemists believe that the certain catalysts synthesize methanol using CO2 as an intermediary, and consuming CO only indirectly. 6. CO2 + 3 H2 > CH3OH + H2O; where the H2O byproduct is recycled via the gas shift reaction: 17. CO + H2O > CO2 + H2, 18. This gives an overall reaction, which is the same as listed above. 19. CO + 2 H2 > CH3OH 4. 5Industrial Process Fig. 4 – Industrial process for creating Methanol 4. 5. 1STEP-1: Feed Production 20. The two main two feed stocks, natural gas and water, both require purification before use. Natural Gas contains low levels of sulphur compounds and undergo a desulphurization process to reduce, the sulphur levels of less than one part per million.Impurities in the water are reduced to undetectable or parts per billion levels before being converted to steam and added to the process. If not removed, these impurities can result in reduced heat efficiency and significant damages to major pieces of equipment. 4. 5. 2STEP-2: Reforming 21. It is the process which transforms the methane and the steam to intermediate reactants of hydrogen, carbon-dioxide and carbon monoxide. Carbon dioxide is also added to the feed gas stream at this stage to produce a mixture of components in the ideal ratio to efficiently produce methanol.This process is carried out in a Reform er furnace which is heated by burning natural gas as fuel. 22. Reaction: Reaction: 4. 5. 3STEP-3: Methanol Synthesis 23. After removing excess heat from the reformed gas it is compressed before being sent to the methanol production stage in the synthesis reactor. Here the reactants are converted to methanol and separated out as a crude product with a composition of methanol (68%) and water (31%). Traces of byproducts are also formed. Methanol conversion is at a rate of 5% per pass hence there is a continual recycling of the un- reacted gases in to the synthesis loop. 24.Reaction: 25. 4. 5. 4STEP-4: Methanol Purification 26. The 68% methanol solution is purified in two distinct steps in tall distillation columns called the topping column and refining column to yield a refined product with a purity of 99% methanol classified as Grade AA refined methanol. 27. The methanol process is tested at various stages and the finished product is stored in a large secured tank age area off the pla nt until such time that it is ready to be delivered to customers. 4. 6How it works on a gas turbine 28. Chemical reaction involved is: It reacts with water to form carbon di oxide (CO2) and hydrogen (H). 9. CH3OH + H2O = CO2 + 3H2 30. The reaction is endothermic and absorbs waste heat at about 300oC. The system performance was predicted using in house process simulator called CAPES and found thermal efficiency of approx. 50% (LHV) when turbine inlet temperature is 1,100oC and compression ratio is 14. The schematic diagram given below illustrates its function. 31. 32. Fig. 5 – Methanol fueled gas turbine process 33. 34. The performance of the gas turbine with steam reforming was recalculated using PRO/II. The same adiabatic efficiency of 87% for compressor and 90% for turbine were used.Similar value of overall thermal efficiency of approx. 50% was obtained as shown in Table-1. For reference, the performance of air heating system was also investigated. In this case, thermal eff iciency was in the same level as reforming but total heat transfer area is 1. 7 times of steam reforming case. Let’s explain model making of steam reformer by PRO/II. After defining stoichiometric data for steam reforming reaction, Gibbs reactor was used for equilibrium calculation at specified temperature. For combustor design, two combustion reactions were defined.Then two conversion reactors were connected in series and set the conversion parameter to 1. Both reactors are defined as adiabatic. 35. Heat exchangers having phase change were split into 10 to 20 zones and flow configurations were set to true counter flow. Minimum pinch points were set to 10 to 20 oC. Pressure drop of each exchangers were set to 0. 02-0. 01 atm and overall heat transfer coefficient were set to100kcal/h C.

MW, twin engine, gas turbine generator unit supplied by Turbo Power and Marine Systems, Inc. (Edison Co. 1981). The methanol was fired as a liquid. Some fuel system modifications were performed to permit the higher mass and volumetric flow of methanol to achieve base load output. Some elastomers in the fuel system were replaced with materials impervious to methanol attack. The tests showed: â€Å"Operations on methanol are as flexible as on natural gas or distillate fuel.The ability to start, stop, accelerate, decelerate, perform automatic synchronization, and respond to control signals is equal to operations on either natural gas or distillate fuel. Turbine performance on methanol is improved over other fuels due to higher mass f low and the lower combustion temperatures resulting from methanol operations. Oxides of nitrogen emissions on them ethanol-fueled turbine, without water injection, were approximately 80% of the emissions of the distillate-fueled turbine with water injection. There was a significant reduction in particulate emissions during methanol operation.An additional reduction in oxides of nitrogen emission was obtained during operations of the methanol-fueled turbine with water injection. No significant problems occurred during the test that could be attributed to methanol. The hot end inspection indicated cleaner components within the methanol-fueled turbine. † During 1984-1985, GE conducted methanol combustion tests of heavy-duty gas turbine combustors in a private study for Celanese Chemical Company, Inc. This work is unpublished. The tests were conducted at GE’s Gas Turbine. Development Laboratory in Schenectady, N . Y.Tests were performed with an MS6001B full-scale combustor representative of GE heavy-duty gas turbine combustors, and an MS7001 developmental dry low NOx combustor. Then ethanol was fired as a liquid, â€Å"dry† and also with water addition. A high-pressure centrifugal pump was used to supply the methanol to the combustor. The tests demonstrated that methanol fuel can be successfully burned in GE heavy-duty combustors without requiring major modifications to the combustor. NOx emissions were approximately 20% of those for the same combustor firing NO. 2 distillate at the same firing temperature.With water addition, NOx levels of 9 ppmv could be achieved. Liner metal temperatures, exit pattern factors, and dynamic pressures were not significantly affected by methanol combustion and met GE criteria for acceptable performance. The results are valid for 2000 F firing temperature machines (E-class). Additional work would be required to confirm performance with methanol fuel, elevated firing temperatures of the F series of machines. Vapor ized methanol will reduce NOx 5% to 10% (relative to CH4 emissions) whereas liquid methanol will reduce NOx 30% relative to CH4 emissions.Water content in the methanol provides further NOx reduction. In 1984, a field test demonstration was performed at the University of California at Davis (California Energy Commission 1986). Methanol was fired in a 3. 25 MW Allison 501-KB gas turbine for 1,036 hours. Low NOx emissions were observed and were further reduced by mixing water with the methanol. Problems encountered with the traditional gas turbine fuel pump were bypassed by using an off-board centrifugal pump. 4. 8Advantages & Disadvantages 37. Methanol is a liquefied form of methane, a naturally-occurring gaseous hydrocarbon produced by decomposition.Currently, methane is burned as a ‘waste† gas at oil drilling platforms, coal mining sites, landfills, and sewage treatment plants. The advantage is methane, and its derivative methanol is that it is extremely plentiful; drill ing for oil, mining coal, and the decomposition of organic matter all produce methane already. As a hydrocarbon similar to propane and petroleum, methane is a very powerful, explosive gas that can easily take the place of petroleum without marked decline in power or major retooling of existing technologies.The disadvantages of methanol is the process by which methane is converted into a liquid at normal temperatures; by mixing methane with natural gas and gasoline, methane is converted into methanol. But the need for gasoline does not entirely wean the United States off of oil, so its â€Å"alternative† status is questionable. Additionally, the process to capture, store, and convert methane is prohibitively expensive compared to gasoline. 38. 4. 9Conclusion 39. Methanol is considered a superior turbine fuel, with the promise of low emissions, excellent heat rate, and high power output.The gas turbine fuel system must be modified to accommodate the higher mass and volumetric f low of methanol (relative to natural gas or distillate). The low flash point of methanol necessitates explosion proofing. The low flash point also dictates that startup be performed with a secondary fuel such as distillate or natural gas. Testing to date has been with methanol as a liquid. GE is comfortable with methanol as a liquid or vapor. GE is prepared to make commercial offers for new or modified gas turbines utilizing methanol fuel in liquid or vapor form based on the earlier experience.Some combustion testing may be required for modern machines applying for very low NOx permits. 5. Power Alcohol 5. 1Introduction Power Alcohol is a mixture of petroleum and ethanol in different proportions and due to these proportions different names are given to each blend like:- 1. As a blend of 10 percent ethanol with 90 percent unleaded gasoline called â€Å"E-10 Unleaded†. 2. As a component of reformulated gasoline, both directly and/or as ethyl tertiary butyl ether (ETBE). 3. As a primary fuel with 85 parts of ethanol blended with 15 parts of unleaded gasoline called â€Å"E-85. (Rex Weber 2003) When mixed with unleaded gasoline, ethanol increases octane levels, decreases exhaust emissions, and extends the supply of gasoline. Ethanol in its liquid form, called ethyl alcohol, can be used as a fuel when blended with gasoline or in its original state. Well the production of ethanol fuel began way back in1907 but Ethanol use and production has increased considerably during the 1980s and 1990s not just due to the lack of fossil fuels but was also due to several other factors 1.Ethanol reduces the country’s dependence on imported oil, lowering the trade deficit and ensuring a dependable source of fuel should foreign supplies be interrupted. 2. Farmers see an increased demand for grain which helps to stabilize prices. 3. The quality of the environment improves. Carbon monoxide emissions are reduced, and lead and other carcinogens (cancer causing agents) are removed from gasoline. 5. 2Chemistry Glucose (a simple sugar) is created in the plant by  photosynthesis. 6 CO2  + 6 H2O + light > C6H12O6  + 6 O2 During  ethanol fermentation,  glucose  is decomposed into ethanol and  carbon dioxide.C6H12O6  > 2 C2H5OH+ 2 CO2  + heat During combustion ethanol reacts with  oxygen  to produce carbon dioxide,  water, and heat: C2H5OH + 3 O2  > 2 CO2  + 3 H2O + heat After doubling the combustion reaction because two molecules of ethanol are produced for each glucose molecule, and adding all three reactions together, there are equal numbers of each type of atom on each side of the equation, and the net reaction for the overall production and consumption of ethanol is just: Glucose itself is not the only substance in the plant that is fermented. The simple sugar  fructose  also undergoes fermentation.Three other compounds in the plant can be fermented after breaking them up by  hydrolysis  into the glucose or fructose molecules that compose them. Starch  and  cellulose  are molecules that are strings of glucose molecules, and sucrose  (ordinary table sugar) is a molecule of glucose bonded to a molecule of fructose. The energy to create fructose in the plant ultimately comes from the metabolism of glucose created by photosynthesis, and so sunlight also provides the energy generated by the fermentation of these other molecules. Ethanol may also be produced industrially from  ethene  (ethylene).Addition of water to the double bond converts ethene to ethanol: C2H4  + H2O > CH3CH2OH This is done in the presence of an acid which  catalyzes  the reaction, but is not consumed. The ethene is produced from petroleum by  steam cracking. 5. 3Production Ethanol can be produced by various methods but the most commonly used in today’s world is by the method of fermentation and distillation of sugarcane, grains, corn etc. 5. 3. 1Ethanol from sugar cane The first stage in ethanol produ ction is to grow a crop such as sugar cane. The sugar cane of cut down and undergoes fermentation and distillation. 5. 3. 2FermentationCrushed sugar cane in placed in fermentation tanks. Bacteria in the tanks acts on the sugar cane and in time produce a ‘crude’ form of ethanol. This is then passed on to the ‘distillation stills’ where it is refined to a pure form. 5. 3. 3Distillation The impure/crude ethanol is heated in a ‘still’ until it vaporizes and rises into the neck where it cools and condenses back to pure liquid ethanol. The impurities are left behind in the still. The ethanol trickles down the condensing tube into a barrel, ready for distribution. When burned it produces fewer pollutants than traditional fuels such as petrol and diesel.Fig. 6 – Distillation process of impure/crude ethanol The production of petroleum is done by the fractional distillation of crude oil. 5. 3. 4Fractional Distillation The various components of cru de oil have different sizes, weights and boiling temperatures; so, the first step is to separate these components. Because they have different boiling temperatures, they can be separated easily by a process called  fractional distillation. The steps of fractional distillation are as follows: 1. You  heat  the mixture of two or more substances (liquids) with different boiling points to a high temperature.Heating is usually done with high pressure steam to temperatures of about 1112 degrees Fahrenheit / 600 degrees Celsius. 2. The mixture  boils, forming vapor (gases); most substances go into the vapor phase. 3. The  vapor  enters the bottom of a long column (fractional distillation column) that is filled with trays or plates. The trays have many holes or bubble caps (like a loosened cap on a soda bottle) in them to allow the vapor to pass through. They increase the contact time between the vapor and the liquids in the column and  help to collect liquids that form at var ious heights in the column.There is a temperature difference across the column (hot at the bottom, cool at the top). 4. The  vapor rises  in the column. 5. As the vapor rises through the trays in the column, it  cools. 6. When a substance in the vapor reaches a height where the temperature of the column is equal to that substance's boiling point, it will  condense  to form a liquid. (The substance with the lowest boiling point will condense at the highest point in the column; substances with higher boiling points will condense lower in the column. ). 7.The trays  collect  the various liquid fractions. 8. The collected liquid fractions may  pass to condensers, which cool them further, and then go to storage tanks, or they may  go to other areas for further chemical processing Fractional distillation is useful for separating a mixture of substances with narrow differences in boiling points, and is the most important step in the refining process. The oil refining proc ess starts with a fractional distillation column. On the right, you can see several chemical processors that are described in the next section.Very few of the components come out of the fractional distillation column ready for market. Many of them must be chemically processed to make other fractions. For example, only 40% of distilled crude oil is gasoline; however, gasoline is one of the major products made by oil companies. Rather than continually distilling large quantities of crude oil, oil companies chemically process some other fractions from the distillation column to make gasoline; this processing increases the yield of gasoline from each barrel of crude oil.Fig. 7 – Fractional distillation of crude oil 5. 4Air pollution Compared with conventional  unleaded gasoline, ethanol is a particulate-free burning fuel source that combusts with oxygen to form carbon dioxide, water and  aldehydes. Gasoline produces 2. 44  CO2  equivalent  kg/l and ethanol 1. 94. Since ethanol contains 2/3 of the energy per volume as gasoline, ethanol produces 19% more CO2  than gasoline for the same energy. The  Clean Air Act  requires the addition of  oxygenates  to reduce carbon monoxide emissions in the United States.The additive  MTBE  is currently being phased out due to ground water contamination; hence ethanol becomes an attractive alternative additive.

Complete combustion: Ethanol molecules contain 35 percent oxygen, and serve as an â€Å"oxygenate† to raise the oxygen content of gasoline fuel. Thus, it helps gasoline burn completely and reduces the buildup of gummy deposits. Prevent overheating: Ethanol burns cooler than gasoline. Fuel Type| Ethanol| Regular Gasoline| Premier Gasoline| E10 Gasohol| E85 Gasohol| Energy Content (/Gallons)| 84,600| 125,000| 131,200| 120,900| 90,660| Table 3 – Energy content of fuelsEnergy content: As shown in Table 2, fuel et hanol contains around 33 percent less energy content than regular gasoline. The energy content of gasohol blends (E10 or E85) is determined by the energy content of ethanol and gasoline, and their ratio. Emissions from ethanol are about 48% of diesel; it is lowest of any of the fuels. â€Å"The clean burning characteristics extend turbine life, possibly by as much as 100%. † (K. K. Gupta 2010) 5. 6Disadvantages Loss of power and performance – Pure ethanol is over 100+ octane, and provides the fuel with much of its octane rating.Because Ethanol burns at a lower temperature than the older (MTBE) gas, boaters can expect to see a 2 to 3 % drop in RPM. â€Å"Use of ethanol in the pure state or as a blend would probably require replacement of any white metal or aluminum in the system as well as some elastomers. † (K.
