Fireworks combine art and science. Discuss the chemistry behind firework colors, including the mechanisms of color production - Essay Example 111). The production of basic firework entails one to have four chemical agents essential in the formation of the entire complex reaction. These reagents or requirements include reducing agents, oxidizers, binders, coloring agents and regulators whereby the latter undertakes the role of controlling heat (Ochiai, 2011). Binders in the production of fireworks ensure each reagent is in its place for various chemical reactions to take place as necessitated, hence produce the required color displays. Oxidizers in this reaction serve the purpose of availing the required oxygen essential for the combustion process (Ochiai, 2011). These oxidizing agents include nitrates, chlorates and perchlorates (Ochiai, 2011). However, their extent of releasing respective oxygen atoms varies greatly during the entire and complex reaction process. Key oxidation reactions resulting from these processes include, Upon the release of O2 in the atmosphere, it encounters with S and C, which act as reducing agents producing their respective gaseous oxides as well as heat. Produced heat in this case increases explosive power of the entire combustion process. Color production during fireworks comprises of two mechanisms, which are Incandescence and Luminescence (Helmenstine, n.d). In the initial mechanism, it refers to a light produced by heat changing into varied colors based on different temperatures that increase with heating. Successive colors produced by this light include infrared, red, orange, yellow and finally white though under effective regulation one can attain his or her distinct color (Helmenstine, n.d). In addition, one can utilize selected metal elements to increase the brightness of a firework, for instance AL, Ti and Mg commonly known to burn brightly at high temperatures (Helmenstine, n.d). Conversely, Luminescence refers to a light produced by external sources mostly

Human Capital - Benchmarking - Essay Example However, many of these benefits are dwindling within the United Airlines Company along with the number of satisfied employees. Talks of terminating the existing pension plans began in 2004. While the plan was highly supported by United Airlines administrators and investors, others were not quite as happy with the possibility. William Swelbar, president of Eclat Consulting in Arlington, VA, believes the investors would like to have seen the pension plans cut before they had to, as though they were letting someone else do their dirty work: â€Å"The question is, will employees be smart enough not to burn the furniture?† (Allison, 2004a). These types of worries imply that the company understands and acknowledges the sinking morale that can come with such a decision, and is considering making that decision despite this knowledge. Causing further distress among the employees is the ongoing arguments surrounding these terminations of the pension plans. Since announcing the possibility that cutting these plans would be the only way out of bankruptcy for United Airlines, several other companies and financial groups have fought with United Airlines regarding the legality of such a decision. The Labor Department, along with the union representing the airlines flight attendants, the Pension Benefit Guaranty Corp., and the International Association of Machinists and Aerospace Workers, has filed objections to many of the events taking place among the administrators of United Airlines: some of these objections came about after United Airlines quietly removed three executives who were vocally against cutting the pension plans and named the airlines as the fiduciary. (Allison, 2004b). Although the airline has since named an independent fiduciary and made some payments into the pension plans, the amount of insecurity fol lowing such allegations is a cause of major unrest among the employees of United Airlines.

Using Metaphors in Organizations Essay Example | Topics and Well Written Essays - 3500 words

Using Metaphors in Organizations - Essay Example This essay stresses that metaphorical way of looking at an organization is a very useful way of understanding the organization, developing new concepts and theories that can help in better management and growth of the organization. This can potentially have a very positive influence on the society and environment as well. The discussion above explains how two different metaphors for the same organization can create completely different perceptions and theories in terms of their operations, people, customers and stakeholders. This paper makes a conclusion that emphasis on metaphors can be considered as one of the oldest, most deeply embedded, even indispensable ways of knowing in the history of human consciousness and also form the basis of some of the most central ideas of understanding a concept. In fact, many theorists have agreed with the three reasons Ortony. These theories state that metaphors provide a compact version of an event; they enable people to predict characteristics that are unnamable, and; they are more vivid emotionally, sensorially and cognitively because they are close to perceived experience. In spite of the power embraced by metaphorical expressions, their exploitation creates lot of misunderstanding of the concept. The positive outcomes of metaphorical expression of organizations as brains can be attributed to the sophistication in information processing systems used by the organization, their capacity to handle huge data, and their ability to think and act strategically.

Dreaming Better Dreams Essay Example for Free

Dreaming Better Dreams Essay There is no doubt everyone has dream. It is an experience that occurs during sleep. However, dreams are not only all about sleeping experience. We have dreams in life and these dreams are the things that we aspire to have, the status that we want to establish, or the kind of life that we long to have in the future. Thus, at times we are daydreaming that we are there, about to fulfill our dreams. In Mark twain’s The Mysterious Stranger Satan was mentioned as ghost standing at the behind the food processor and admiring a person’s lawn-mowing skills. It was not clear whether it was a dream but dream sometimes appears as one’s night mare. In the ensuing conversation between Satan and the person, Satan says â€Å"dream other dreams, and better† (120). Here, it was not clear whether Satan was advising the person to have a better ambition in life or he was just inciting a person to think of something beyond what he can do in order to make sin. But what ever is Satan’s intension, there is a truth in his statement. One should really have dreams life, a better dream. Dreams as some psychologist say are simply product of our imagination. They say, when we are asleep, our sub-conscious mind becomes active which us to dream dreams. No one likes bad dreams, but everyone enjoys good dreams. In dream, we can do anything that is impossible in real life and when we are awakened we regret that it was only a dream. The truth is we can dream a better dream that is not merely product of our subconscious mind when we are asleep. Our dreams can turn to reality if we could overcome anything that limits us. Our dreams can be fulfilled if we let all our strength, courage, strength, wisdom, and all our best efforts to pull together for a single purpose, achieving our better dreams in life. An ill Time to Laugh In the Bible, particularly in Ecclesiastes chapter 3, the writer states that â€Å"there is a time for everything in this life. There is â€Å"a time to be born and a time to die†, â€Å"a time to weep and a time to laugh. † This is true even today for most us. There is a proper time for everything. In the second prompt, the context tells us that â€Å"Satan laughs at Theodor and at Theodor’s sheepish neighbor who all throw stones at the hanged woman†(109). The scenario led us to think of something dreadful. We do not exactly why the woman was hanged perhaps she was caught in adultery, or that she was a witch but it looks like neighbors were against her who all throw stones at her while she was hanging dead. The only person conscientious of what is going on perhaps is Theodor. Theodor said to Satan, â€Å"It was ill time to laugh, for free and scoffing ways†¦brought him under suspicion. † Satan protested in this statement saying, â€Å"There spoke the race† â€Å"always ready it hasn’t got †¦ you have perception of humor, nothing more; a multitude of you possess that. This multitude sees the comic side of a thousand low-grade and trivial things-broad in-congruities, mainly: grotesqueries, absurdities, evokers of the horse-laugh† (109). There is something we can learn from this statement. Many people see only the comic side of the things around them or of the people they met and laugh at them. We tend to be evokers of the horse-laugh rather than objective in our judgment of anything that we see on others. Most of the time, we laugh at people even when it is an ill time to laugh. Perhaps, our problem is that we could hardly see when the right time to laugh on other people is. The best thing perhaps for us to avoid becoming evokers of horse-laugh is to always bear in mind the biblical statement, â€Å"there is a time weep and a time to die. † Reference Twain, Mark â€Å"The Mysterious Strangers†

Edgar Allen Poe Essay example -- Biography Biographies Poe Author Essa

Edgar Allan Poe Edgar Allan Poe was born at 33 Hollis Street, Boston, Massachusetts, on January 19, 1809. Poe’s parents were struggling actors. His father deserted him, and his mother died of tuberculosis when he was three years old. Young Edgar was taken in by a wealthy tobacco exporter by the name of John Allan, from whom he took his middle name. Most of his early life was lived in Richmond, Virginia, with the exception of a five-year period when the Allan family lived in England. His life in England was described as rather uneventful. Poe, even in his early years, had a proficiency for writing poetry. When he moved back to Virginia, Poe grew attached to young girl in his neighborhood named Sarah Royster. They frequently visited, where they sang songs and drew pictures. They were secretly engaged at the time, although their intentions were not made known to the adults of either household (Allen 9). His mid-life began when Poe entered the University of Virginia in 1926. He withdrew less than a year later. Initially, his grades were brilliant, but soon thereafter they began to deteriorate. It is reported that Poe gambled heavily and owed large sums of money to various shopkeepers (Benet 34). He also began drinking quite heavily. Mr. Allan refused to pay Poe’s debts. He also broke off Poe’s engagement to Sarah Royster. Without any visible means to support himself, Poe left for Boston. In the spring of 1827, he arrived penniless and enlisted in the army under the name of Edgar A. Perry. In 1829, he was promoted to the rank of sergeant major. At his own request, was honorably discharged in April of 1829 (Gullete 5). Temporarily reconciled, Mr. Allan secured Poe an appointment to West Point. But still refused financial support. After six months, Poe purposely got himself discharged from West Point, by purposely neglecting his military duties and for disobedience of orders (Encarta [CD-ROM]). Poe then moved to New York, and with the help of some money raised by his West Point friends, he published his first poems in 1831. Poe next took up residence in Baltimore, with his widowed aunt, Maria Clemm, and her daughter, Virginia. He turned to fiction as a way to support himself. The Philadelphia Saturday Corrier published five of Poe’s stories. In 1883, one of his pieces won a fifty-dollar prize given by the Baltimore Sunday advisor (Regan 2,3). In 1... ...il in a story should contribute to the story. Words must not be wasted. Poe’s life was short. He died at the age of forty. He did not appear to waste a moment of his life. He moved from Boston, to Philadelphia, to New York, and to Richmond in the early 1800’s. He even spent five years in London, England. All of these experiences shape his odd life. All of his experiences in his lifetime, including the bad memories, reflected how he wrote his literature. The reader had to understand every aspect of his life to better understand his stories and poems. His writings have been teachings and inspirations for the authors today. Poe is one of the most famous authors in today’s world because of his odd tales, and his eerie life. Works Cited Abbey-Cormier.
