Human Interference Of The Atmosphere - 1156 Words

Greenhouse effect is the process where heat is trapped by greenhouse gases present in the atmosphere to keep the Earth warm. The planet’s atmosphere contains these radiatively active gases, that radiate energy in all direction. Greenhouse gases are already present in the atmosphere; without them the Earth would be significantly cold enough to freeze the oceans. To understand how important and harmful the greenhouse gases can be for the planet, we need to answer these questions. Do extra greenhouse gases upset the Earth’s natural balance and make it even warmer? Is there any extra insertion of the gases in the atmosphere by humans? If so, how significant are the effects? This essay will discuss in detail, the mechanism that†¦show more content†¦How is radiative equilibrium achieved? The global surface temperature averaged over daily and seasonal series, remains constant. Earth surface receives 340 watts/m2 of radiant energy, if the global surface temperature ave raged daily remains constant, therefore Earth’s surface must be radiating out energy precisely 340 watts/m2 into space to keep the surface cool. There are many greenhouse gases in the atmosphere, the two most abundant are water vapour and carbon dioxide. Visible light (short wave radiation) passes through the green house gases to reach the Earth’s surface, The Earth surface absorbs short wave radiation, the radiation is then released by the surface in the form of infrared radiation. Only 10% of the infrared radiation released passes through the gases and the atmosphere and escapes. The rest of the infrared radiation is trapped by the greenhouse gases and clouds. What really causes the greenhouse effect? The remaining infrared radiation is trapped by the green house gases. The greenhouse gases in turn reradiates the infrared radiation in all direction. Some of the radiation go into the outer space and some go back to the Earth surface. The continuous cycle of exchange of infrared radiation between the Earth’s surface and the greenhouse gases is called the greenhouse effect. The presence of an atmosphere containing greenhouse gases keeps the Earth surface warm, without an atmosphere like

Comparing Death of a Salesman by Arthur Miller and Fences...

Comparing Death of a Salesman by Arthur Miller and Fences by August Wilson Death of a Salesman by Arthur Miller and Fences by August Wilson have similar themes of conflicts between fathers and sons, conflicts between husbands and wives, and the need to focus on a small unit of space in order to achieve success. In the process of developing these themes throughout the two plays, three similar symbolic elements are used including the insecure father figure, the other woman, and the garden. The fathers in the two plays are comparable because they both have conflicts with their sons as a result of living in the past, and they die in the end. Willy, in Death of a Salesman, is never respected for his occupational status, so he†¦show more content†¦Afraid I was gonna be better than you. All you ever did was try and make me scared of you (1913). Although Cory is a skilled baseball player, Troy always discourages him from playing professionally. Troy is never given the chance to play because he is black, but athletics is a field that is fully open to blacks later, when Cory is ready to play. His father is unable to recognize this fact because he always lives in the memory of past events; he pressures Cory to be much better than all the white baseball players. This conflict is never really resolved because even at his fathers funeral, Cory feels much resentment towards his father and almost does not attend the funeral. He has not yet separated himself fro m his fathers dominance and is just beginning to find a way to get rid of that shadow (1918). Therefore, both of the insecure father figures make unrealistic demands on their sons until their sons are forced to separate themselves completely from their fathers influence. While the role of the insecure father figure is to generate conflicts between fathers and sons, the role of the other woman is to spark another kind of conflict between husbands and wives. In Death of a Salesman, although Linda never finds out about the Woman, her relationship with Willy is still affected by the Woman. For example, Willy says, Will you stop mending stockings? At least while Im in the house. It gets me nervous. I cant tell you (1745).Show MoreRelatedComparing Death of a Salesman by Arthur Miller and Fences by August Wilson 1403 Words   |  6 PagesFences written by August Wilson and Death of a Salesman written by Arthur Miller are two plays that could be considered very different in terms of their plot.

Levi and Strauss Co Free Essays

Levi Strauss Co. is a flourishing business. Since the early days, it has been a leader in the garment industry. We will write a custom essay sample on Levi and Strauss Co or any similar topic only for you Order Now The original and most famous Levi Strauss product is blue jeans. Jeans have become desirable and even fashionable clothing for not only miners, farmers, and cowboys, but also for movie stars, executives, women, children, and teenagers from all over the world. Throughout its history, however, the company has researched and developed a number of other products. The company now markets a wide range of clothing and accessories, all under the brand name Levi’s. Many new Levi products have been launched over the years. Some of these have succeeded beautifully, but others have flopped completely. The company is still best known, however, as the maker of Levi jeans, the pants that are guaranteed to shrink1, wrinkle, and fade2. In 1954, flushed with the success of the cotton twill pants it had introduced a few years earlier, Levi brought out a line of permanent press (no-iron) slacks. Within six months, 5 out of every 100 pairs sold had been returned, and Levi had to admit it didn’t have the right fabric for permanent press. Fifteen years later, as the company was planning its major expansion, it hit on a couple of equally dramatic flops. First was the denim bathing suit—which, when wet, weighed the wearer down to the point of imminent drowning. Next was a line of disposable (throw-away) sheets and towels. These, Levi discovered, were not high on the consumer’s list of priorities. Unable to interest hotels in the product, the company was saved when the factory that made the sheets burned down. Levi absorbed the $250,000 loss. Eventually Levi created six new divisions, ranging from jeans to accessories and including a sizable effort in women’s sportswear, Levi’s for Gals. The diversification3 worked. In the mid-1970s Levi’s sales hit the billion-dollar mark, having taken 125 years to reach that milestone. Four years later sales hit $2 billion. In 1979 the company ranked 167 on Fortune’s4 list of the 500 largest industrial corporations, and 20 in net profits. 5 Between 1970 and 1980 Levi had grown an average of 23 percent a year. In 1979 alone it sold 143 million garments. In menswear, though, all Levi products had been aimed at the middle of the market. The company had brought out a line of moderately dressy slacks and polyester leisure suits—the Action Slack and Action Suit—and was doing a brisk business with them. But the tempting upper end of the market remained untouched. â€Å"If we want to grow we’re probably going to have to go to upper moderate price points,† one Levi official explained, â€Å"and somewhat higher taste level for our products. In short, they needed to sell more expensive clothes—like the Tailored Classic. If Levi could sell sport coats, dress slacks, and, above all, suits, a whole new market would open up. The Tailored Classic might make money all by itself. But even more important, it would get Levi into the business of producing fancier and costlier clothing. The consumer would come to think of it as a manufacturer of dress apparel and it could sp in off6 many more such lines in the future. Why, with such a record of success would any company be worrying about making new products? Part of the answer, obviously, is the sheer riskiness of depending so heavily on a single item. The boom in jeans was in many ways a historical accident, and what history has given it can also take away. Then, too, the demographics of the marketplace were already beginning to change. Jeans, to be sure, were no longer the exclusive province of youth: baby boomers7 who had grown up on Levi’s kept on wearing them into their twenties. But they would no longer be wearing them everywhere and all the time, as they did when they were teenagers. And the next generation of adolescents was not so numerous. The birthrate had peaked in 1957; by 1964, demographers agreed, the baby boom in the United Stated was over. The bulge in the population that the boom had created would soon be moving into a world of casual slacks, leisure suits, and coats and ties. From a marketing point of view, that’s where the action would be. Finally, the competition had been gearing up. Levi’s had always shared the market with Blue Bell’s Wranglers and other national brands like Lee. But now everyone seemed to be selling jeans. Back in 1970 Levi probably couldn’t have foreseen the popularity of â€Å"designer† jeans skimming off8 the upper end of the market. But they could certainly anticipate cut-rate models gnawing away at the low end. To sell their wares, Levi knew, retailers would have to slash prices. The profit outlook in a saturated, competitive marketplace like this was bleak. Adapted from: Boyd, F. (1994). Making Business Decisions: Real Cases from Real Companies.

Linguistics Presentation World Ancient Languages

Question: Discuss about theLinguistics Presentationfor World's Ancient Languages. Answer: Introduction It is important to revive the language like what happened to Hebrew since the data is required for assistance in the study of linguistics and for the purpose of understanding their evolution. The majority economy s dependent on these languages especially English used for trading and in business. It is necessary to record any unwritten language in order to make sense in science. Language should be protected for comparison purposes with a variety of different languages since it is intimately connected with the rituals that are unique to a particular culture hence there is mutual benefit which makes it difficult to preserve one without the other. To overcome the voluntary reasons of losing the language there is need to encourage acceptance in first language by individuals. Life has been regarded as a constant battle with linguistics imperialism hence the individuals in knowing about other cultures by reading from the historical records strengthens themselves mentally. The benefit of producing physiological change in the brain is obtained by study of languages and embracing diversity. The learning of important skills such as basket weaving is facilitated by the last Native American speaker who spreads it over to the interested learners by use of the language. The master apprentice programs like the one used in Hawaii are basics to protection of language and has enabled development of systems of writing which never existed before. Kaplan (2002) said The Oxford Handbook of Applied Linguistics is an example of records that have showed importance of language. The minority languages have no business conducted in them hence they can easily be depleted. Preservation can be used to bring back the language from the dead and this the reason why language needs to be protected because nowadays people are only interested with conducting trade using a particular language. Woodard (2004) argues that The Cambridge Encyclopedia of the World's Ancient Languages has preserved many minority languages. Knight (1999) says it is important to protect languages to prevent it from dying at the end of the century. The persistence use of the same language for example English may lead to extinction of another minority language. The language is used for research purposes and also studied in school curriculum in linguistics and understanding of other subjects. The preservation of language benefits the researchers in accessing the information that they require while undertaking a particular project. References Woodard, R. (2004).
