Cars Technical - Essay Example After World War I, the United States became a renewal of economic growth, from new inventions to growth of an expanding road infrastructure. This economic growth helped accelerate the need for the automobile. The automobile industry grew quickly because of many innovative inventions. In the 1950's innovation was getting greater speed through the design of more powerful engines. In the 1960's innovation was building a sleek but performance driven auto. In the 1970's, the automobile and gas shortage led many automakers to look for innovative ways to control emission and decrease gas consumption. The convergence of computer and auto industries helped improve gas mileage and cut down on emission. The last 25 years of the car industry has seen technical and design advances that increased standardization, platform sharing, and CAD design. Body styles have changed to include the hatchback, minivan and sport utility vehicle (Consumer Guide p 10). Automotive engines are called internal combustion (IC) engine because the fuel that runs them is burned internally, or inside the engines. There are two types, reciprocating and rotary. Reciprocating means moving up and down, or back and forth. Almost all automotive engines are of the reciprocating type. In these engines, pistons moves up and down, or reciprocate, in cylinders. This type of engine is called piston engine. Rotary engines have rotors that spin, or rotate. The only such engine now used in automobiles is the Wankel engine. 1 )Types of Engine System: 1.1 Car Engine: The main function of a car's engine is to make it move. Engines come in a range of strengths as well as speeds. All recent engines are made of vital parts. Car engines are built around cylinders (generally something from 2-12 of them, however usually 4, 6 or 8) in which the fuel is burnt. Super-strong metal and sealed shut, arte used to make these cylinders however at one end open and closes exactly like bicycle pumps: these consist of tight-fitting pistons (plungers) that may slide up as well as down in them. At the top of every cylinder, there are two valves. The inlet valve permits fuel as well as air to go into the cylinder; the outlet valve lets the exhaust gases loose. At the very top of the cylinder, a sparking plug (or spark plug) is present, this is a device which is controlled electrically as well as makes a spark to put fire to the fuel. At the base of the cylinder, the piston is connected to a continually turning axle that is known as a crankshaft. The crankshaft's function is to powers up the gearbox of the car which then drives the wheels. The capacity of an engine function is depends on the power or the horse power that i t develops. This in turn is reliant on the ability of the engine. 2.)Diesel Engines: In 1892, Rudolph Diesel, a German engineer developed the "diesel" engine. Unlike the gasoline engine, the diesel engine is capable of spontaneous combustion of liquid fuel without requiring spark ignition. "The key advantage of the diesel engine over the gasoline engine is its fuel economy as well as durability" (en.wikipedia.org/wiki/Diesel_engine). Known as a "workhorse" the diesel engine became the engine of choice for heavy construction machinery, mining

Near Earth Objects (NEOs) Research Paper Example | Topics and Well Written Essays - 2000 words

Near Earth Objects (NEOs) - Research Paper Example Depending on how close they are to the Earth, they can be spotted with the naked eye, or they can be spotted with a telescope. Rather than clustered together, a comet is a single large object with a long tail. More often than not, it is the tail, and not the main part of the comet that can be seen. Near Earth Objects might be fun to look at, but they are capable of doing catastrophic damage. Craters around the world pay homage to the respect that they undoubtedly deserve. One of the most widely accepted theories for the extinction of dinosaurs is that a massive meteor struck the planet and radically changed both climate and atmosphere. Fortunately, when it comes to this modern age, there are methods and theories in which to deflect NEOs. All of these are untested, however, and have only performed in labs. A meteor, or meteorite, is a body of rock, ice, or metal that enters the Earth’s atmosphere. Many of these are small and harmless, and burn up upon entering the atmosphere. W hen you see a shooting star, or a meteor shower, that is what you are seeing. While no threatening meteors have recently struck the Earth’s surface, the evidence is all around us. The largest crater in the world, created by a meteor, is in South Africa in an area called the Vredforte Dome. This meteor hit the Earth more than 2 billion years ago, and was around 10 km in diameter. According to science, the impact of the meteor might have been massive enough to jumpstart multicellular life by increasing the amount of oxygen in the atmosphere. There are, to date, 841 World Heritage sites around the world. A World Heritage site is a special place that has either a cultural or a physical significance. These sites are chosen by the UNESCO (United Nations Educational, Scientific, and Cultural Organization), which has been around since 1945. While Earth appears safe for the most part, it has had its share of close calls. One such close call occurred in September of 2004. An asteroid b y the name of Toutatis swept by Earth, missing it by about a mile. Several kilometers in diameter, if Toutatis or a rock like it were to hit Earth, it would devastate life as humans know it. The sun would be obscured by a huge cloud of dust that would travel around the globe, changing the temperature and climate of the Earth. Plants would start to die from lack of sunlight, unable to complete their cycles of photosynthesis, and herbivores would begin to starve. Humans would have major crop failure as well, and would need to resort to another means of sustenance. Eventually, over time, civilization would cease to be. Food, if any survived at all, would be both precious and hard to come by. Water would become stagnant and toxic to drink, as the evaporation process would be altered without sunlight. The impact of a NEO of this size would ultimately either destroy all life on the planet, or force evolution into overdrive. A rare NEO that is usually only seen by astronomers with high-pow ered telescopes and other special equipment is the comet. These massive objects are made up of ice and organic material. They carry behind them a long ‘tail’, which consists of ice and other materials that it picks up as it hurtles through space. The ‘head’ of the comet is called a nucleus, which consists of the ice and organic materials. The core of the nucleus is as yet unknown. These beautiful objects are far older than many of the planets in the solar system, the majority of them estimated to be

How Investing Became Cool Essay -- Internet Stock Market Essays

How Investing Became Cool Bankers and stockbrokers are not generally viewed as the most exciting people in the world. Traditionally, they have been viewed as those guys who are always reading the Wall Street Journal or talking on their cell phones when they're out in public; they wear the same white shirt, red tie combination every day of the week, and there's no noticeable distinction between work and the rest of their lives. Not exactly the kind of people you'd want to invite to liven up a Christmas party. And if you do invite them, they usually end up standing before a group of bored and confused laymen talking about hedge funds or IPOs. This was a common perception in the past, but within the last decade this image has changed considerably. The field of finance and investments has seen a considerable increase in popularity, and these same bankers and stockbrokers might even be considered cool now. The 1990s saw the climax of the longest bull market in recent history. As John Cassidy pointed out in an article for the New Yorker earlier this year, interest rates were low, unemployment was low, and thanks to the Internet bubble the Nasdaq was climbing at an unbelievable rate. To the average American, it started to become apparent that the stock market was a good place to turn to make a quick and easy profit, and the seemingly infinite growth made it seem like an almost risk-free investment. Soon everybody was talking about stocks like they were the newest and hottest fashion trend, and it was impossible not to notice. In a recent Money magazine article, Joseph Nocera says that in 1994, 34% of American households had some money in the market, up from just 10% in the 1950s, and this number climbed even further to mo... ...rk on Main Street. If you've understood everything I've said without too many visits to a financial dictionary, then you've proven my point. For the most part, the American public has been educated, and stock market lingo has made its way into everday speech. Perhaps it is only a matter of time before a diversified portfolio becomes as much a part of the American Dream as apple pie and white picket fences.

Analysis on Materialism and Pink Flamingo Essay

â€Å"Materialism coarsens and petrifies everything, making everything vulgar, and every truth false.† These profound words spoken by Swiss philosopher Henri Amiel illustrate the wretched vulgarity and superficiality of the virus-like spread of materialism. In the essay entitled â€Å"The Pink Flamingo: A Natural History† by Jennifer Price, Price examines the popularity of the well-known pink flamingo and how it relates to the ideals and whims of American culture. Using American fascination of the plastic, pink flamingo as her medium, Jennifer Price shows her evident disdain for the superficial materialism present in American society. Jennifer Price introduces her analysis of the flamingo fad by presenting the rise of the pink flamingo in American culture and how society reacted upon the popularization of this cultural icon. Price effectively illustrates the American public’s reaction to the introduction of the plastic, pink flamingo by implementing specific diction that reinforces her own opinions of the â€Å"flamingo boom†. Similar to a mindless flock of birds following each other without much thought as to why, Price writes that â€Å"Since the 1930s, vacationing Americans had been flocking to Florida and returning home with flamingo souvenirs.† Price’s choice to describe Americans as â€Å"flocking† is meant to establish a comparison to a flock of mindless birds; in effect, the author characterizes Americans as bandwagon followers who lack any consideration for the examination of their culture and the conceptual purpose behind their symbolic icons. The author also presents how Americans have rendered the plastic, pink flamingo as symbolic of wealth and luxury. Price states that â€Å"In the 1910s and 1920s, Miami Beach’s first grand hotel, the Flamingo, had made the bird synonymous with wealth and pizzazz.† In the context of the essay, terms like â€Å"wealth† and â€Å"pizzazz† possess a shallow, superficial connotation that consequently translates into the flamingo as not only being a symbol of wealth and pizzazz but also a symbol of superficiality and vulgar ostentation. Price’s introductory paragraph is significant to the purpose of the essay because it illustrates the magnitude of the flamingo fascination and how Americans irrationally react to the flamingo’s popularity. In reiteration of Price’s stance, heavy criticism in the essay of the plastic  flamingo’s intrinsic boldness simply because it represents an exotic creature depicts Price’s severe disdain for the whims of American society. Price utilizes an ironic situation in conjunction with historical evidence when she attempts to establish a connection between real flamingos and plastic flamingos. Americans, Price points out, â€Å"had hunted flamingos to extinction in Florida in the late 1800s, for plumes and meat. But no matter. In the 1950s, the new interstates would draw working-class tourists down, too.† Price bluntly uses facts and historical research about American culture to express her disgust of the irony that the American nation has created for itself with regards to the plastic, pink flamingo. When Price writes â€Å"But no matter,† she reinforces the implication that it is as if American society regards the destruction of the flamingo as trivial b ecause capitalist society would benefit more from the production of plastic flamingos that could yield revenue. Thus, a nation that embraces the flamingo in all its beauty after having been so destructive of the natural population reveals the ironic carelessness and hypocrisy of American society. Furthermore, Price uses the image of the pink flamingo with its natural boldness to emphasize her point about the ignorance of Americans and their culture. The author states, â€Å"The bird acquired an extra fillip of boldness, too, from the direction of Las Vegas with†¦Flamingo Hotel. Anyone who has seen Las Vegas knows that a flamingo stands out in a desert even more strikingly than on a lawn.† The simple fact that a flamingo is a subtropical animal unfit to live in the desert gives Price the justification to illustrate how Americans took the flamingo fad to such extreme heights without giving one regard to the appropriateness of the flamingo in context. In doing so, Price once again conveys the total ignorance and lack of consideration that characterizes American society. The paragraph in which Price asserts her belief regarding the ironic situation American society has put itself in supports a belief that Americans have taken their obsession so far as to having destroyed a population of animals for the sake of wealth and luxury; thus, the pink flamingo, in the context of Price’s essay, is merely a symbol of the vulgar materialism Americans possess because of their ignorance and inconsideration for the appropriateness of destroying flamingos and â€Å"plasticizing† them. Jennifer Price provides further details regarding the plastic flamingo’s image which forces the reader to question if the plastic flamingo is even close to being a valid representation of its real-life counterpart. Price’s use of imagery in her essay and the interpretation that follows shows that she believes the plastic flamingo is obviously not even fit to represent the true flamingo. Price lists the colors, â€Å"tangerine, broiling magenta, livid pink, incarnadine, fuchsia demure, Congo ruby, methyl green,† in order to establish images that overwhelm the reader’s mind with bold colors. The extremely bold colors of the plastic flamingo such as â€Å"livid pink† and â€Å"broiling magenta† formulate the conclusion that the plastic flamingo could never be synonymous with the quiet, demure brilliancy of a real flamingo. Thus, once the reader has interpreted the color imagery and concluded that all of the colors are just â€Å"too much†, the reader can make the connection that society is also â€Å"too much† obsessed with putting on pretenses of wealth as opposed to focusing on issues that really matter such as the preservation of the real flamingo. Price also makes use of repetition in order to express the magnitude of the plastic flamingo’s color in society. Jennifer Price states, â€Å"Washing machines, cars, and kitchen counters proliferated in passion pink, sunset pink, and Bermuda pink.† By stating that the pink fad present in the plastic flamingo was also transferred into household appliances such as washing machines and kitchen counters, Price implies that the materialism and vulgarity of appearing wealthy spread into the home; the infiltration of materialism into the home meant that the desire for wealth and extravagance had also infiltrated the aspects of America n life. Price’s criticism of the flamingo’s color fascination supports the essay’s idea that Americans are only satisfied by boldness and extravagance as evident in the pink coloration of household appliances because pink was the color of the symbolic pink flamingo of wealth; Americans, thus, have difficulty equating modesty and demureness with any sort of wealth. The simple belief is that extravagance and flamboyance are the way to go if one wants to appear wealthy. Americans who desire wealth are therefore subject to the whims of materialism and superficiality. The author concludes by delivering an argument that criticizes American views and ideals, or the lack of, as being disrespectful and insulting towards the  significance of the flamingo itself. Jennifer Price uses cultural evidence from other nations to present the importance of the flamingo. She states, â€Å"People†¦have always singled out the flamingo as special. Early Christians associated it with the red phoenix. In ancient Egypt, it symbolized the sun god Ra. In Mexico and the Caribbean, it remains a major motif in art, dance, and literature.† The author uses these facts to justify that the reduction of the brilliant flamingo in American culture to a mere plastic souvenir attached to grass is a shameful comparison to other cultures that respect nature and revered the bird as a glorious symbol. Price then makes use of parallelism in order to strengthen her criticism of American culture. In the essay, Price states, â€Å"No wonder that the subtropical species stood out so loudly when Americans in temperate New England reproduced it, brightened it, and sent it wading across an inland sea of grass.† By using repeating sentence structures through parallelism, Price emphasizes that Americans have done so many things to the flamingo that the plastic version is so far removed from its original counterpart. Thus, Americans have lost sight of the intended genuine meaning behind embracing the flamingo in the first place. The significance of this section within the essay is important because it not only allows the author to go beyond criticism of the flamingo, but it also shows that, in the grand scheme of things, Price was more intent on exposing and criticizing the true validity of all American cultural values. Jennifer Price allegorized the fascination of the plastic flamingo in order to establish a sort of comparison between obsession with purchasing plastic flamingos that symbolize wealth and the materialism evident in American culture. Although the essay mostly depicts American society as insensitive and inconsiderate according to the author’s tone, the satirical nature of the essay provides a subtle, underlying, hopeful connotation that perhaps one day American society will learn to go beyond their materialistic greed and ascend to a different type of wealth.

Expressing Emotions Interjections and Exclamations

You will need quite a bit of experience in, and understanding of, a culture to speak Japanese naturally. If the proper expression does not come to mind instantly, it will sound like you are reading it. When you have a chance to hear the Japanese speaking, listen carefully to the way they speak as well as to their facial expressions. If you are interested in these exclamatory expressions, Japanese comic books (manga), which include many of them, might be good a resource to explore. Here are some of the widely used expressions. Remember that exclamations are used almost always in the  informal style. A, Aa Oh. A, nagareboshi da! Oh, thats a shooting star! Aree, Oya, Maa Oh my! Gee! Maa, kirei na nagame nee! Oh my, what a nice view!(Maa is used by women only.) E What? E, Shigoto yameta no. What, you quit your job? Masaka! No kidding! Masaka sonna koto ga aruhazu nai yo! That cant be! Hee! Really! Hee, sore wa yokatta ne! Wow, thats great! Naruhodo I see. Naruhodo, sou iu koto datta no ka. I see, thats the way it was. Yare yare Oh boy! Yare yare, nante koto da! Oh boy, what a disaster!

This book provides a comprehensive and insightful psychosocial analysis of human development across the lifespan. It encompasses a vast array of purported psychosocial developmental theories which are applicable to all practices within the helping professions and in general, corresponds primarily to the course of a human life. This book has 12 chapters where chapter contents include: the birth of a human being: what makes us who we are; a secure base: the importance of attachment; adolescence, identity and change; family systems and their life cycle; growing up with a disability and; themes in old age. Each chapter is supplemented with a brief summary and an activity section which allows readers an opportunity to become more engaged with chapter contents as well as facilitate critical thinking. The book concludes with a references and index section. Beckett and Taylor in chapters 3 through 5 and 8 covered the principles of attachment, cognitive development, behaviorism and the family systems theory respectively. Attachment theory â€Å"is based on the proposition that the way we relate to others throughout our lives is shaped by our first relationship with our primary carer, who traditionally and still usually is the mother† (p. 41). Key to the development of attachment theory is John Bowlby who is affectionately dubbed the â€Å"father† of attachment theory (p. 41). Bowlby’s theory asserts that external factors influence a child’s development; particularly the impact of separation

I made sure that I am physically fit, had ate and drink well before going to work because sometimes if carers are unwell and have not eat or drink the level of patience and passion to care for the service users were affected which could make them becoming more agitated and distressed. 1.3 Outline how other health and emotional conditions may affect the nutritional needs of an individual with dementia An example of how other health and emotional conditions could affect the nutritional needs of an individual with dementia is depression, as this could lead to a loss of appetite and also a lack of interest in food and drinks. For example, Mrs B has been depressed for quite sometime due to the death of her husband. She would prefer to be on her own most of the time. As a result of her lack of socialisation she became socially isolated. This affected her nutritional needs, as she didn’t feel like eating. It took a long time until she agreed to go to the dining room at meal times. Once dinner was served she would lose interest in eating and tended to return to the lounge without touching the meal.
