English Composition - Essay Example Caffeine and nicotine stimulate the body and eases drowsiness and tension, but these are addictive drugs that harm the body. Caffeine is a xanthine alkaloid compound that acts as a stimulant in humans and the coffee bean is the primary source of caffeine (Caffeine, 2007). Apart from coffee, it is also present in tea, soft drinks, energy drinks, and chocolates. The Coffee Research Institute states that there were 108,000,000 coffee consumers in the United States in 1999; and in 2000 the National Coffee Association’s research indicates that 54% of the adult population in the US drinks coffee daily with an average of 3 cups (Coffee Research Institute, 2006). Apart from caffeine, nicotine is also an addictive drug that can be bought even in convenience stores. It also stimulates the body and causes a sort of relaxation (Nicotine, 2007). Tobacco is the primary source of nicotine. In the United States, studies have concluded that the number of smokers had decreased but the curiosity of the young people is still unquenched. In 2005, the National Survey on Drug Use and Health (NSDUH) discovered that an estimated 71.5 million Americans aged 12 or older are current users of tobacco product ((Office of Applied Studies, 2005). NSDUH further notes that among youths aged 12 to 17, 3.3 million used tobacco products in the past month, and 2.7 million of whom used cigarettes. Most of the young people smoke out of curiosity, while some start drinking coffee and caffeine products to counter drowsiness especially when they are studying or rushing on a project. While caffeine and nicotine cause some sort of stimulation to the body, continued intake of these substance is addictive and can harm the well-being. The effect of caffeine to the human brain is likened to that of amphetamines, cocaine, and heroin; although caffeine is milder (Brain, 2007). Caffeine dependence can lead to unpleasant physical and mental conditions including nervousness, irritability, anxiety,

Importance of Chemistry in Chosen Profession Essay Example for Free

Importance of Chemistry in Chosen Profession Essay The international year of Chemistry (2011) should be the key point in a significant growth of the diffusion of chemistry to show society its importance, how it is necessary, which can provide, in order to put it in the appropriate place to be considered by the public. Different activities have been carried out in almost all the science faculties of the Spanish Universities during 2011 to develop the interest in chemistry. Those activities also include the collaboration with teachers in levels before to the University. The Faculty of Science of the University of Extremadura, as well as, in our case, a group of professors, PhD and PhD students are carrying out actions of divulgation of science including chemistry. The aim is to carry out chemical laboratory experiences for high-school students. Experiences in the laboratory were structured in response to different levels of difficulty and looking those more attractive or those that could hit the students. Addressed aspects were related to spectroscopy, surface tension, oxidation, reduction, precipitation, acidity, chromatography, liquid – liquid distillation, etc. The students worked in each activity in groups no larger than 4-5 students and they carried out the experience with the help of the instructor. It is noticeable the great number of activities described in the literature, in the network, etc., for the diffusion of chemistry. However, a crucial aspect is the form in which those experiences are carried out, as well as the participation of the students is active and the goals such as awaken the interest in science in general and chemistry in particular are achieved. Another point is to involve the university community especially the youngest in the necessity to spread the knowledge and the interest in science. We present a catalog of chemical experiences and a plan to be developed extensively to all the levels previous to the university, including primary school level. . Answer: Chemistry has a reputation for being a complicated and boring science, but for the most part, that reputation is undeserved. Fireworks and explosions are based on chemistry, so its definitely not a boring science. If you take classes in chemistry, youll apply math and logic, which can make studying chemistry a challenge if you are weak in those areas. However, anyone can understand the basics of how things work and thats the study of chemistry. In a nutshell, the importance of chemistry is that it explains the world around you. Chemistry Explains * Cooking Chemistry explains how food changes as you cook it, how it rots, how to preserve food, how your body uses the food you eat, and how ingredients interact to make food. * Cleaning Part of the importance of chemistry is it explains how cleaning works. You use chemistry to help decide what cleaner is best for dishes, laundry, yourself, and your home. You use chemistry when you use bleaches and disinfectants and even ordinary soap and water. How do they work? Thats chemistry! * Medicine You need to understand basic chemistry so you can understand how vitamins, supplements, and drugs can help or harm you. Part of the importance of chemistry lies in developing and testing new medical treatments and medicines. * Environmental Issues Chemistry is at the heart of environmental issues. What makes one chemical a nutrient and another chemical a pollutant? Importance of Taking Chemistry Everyone can and should understand basic chemistry, but it may be important to take a course in chemistry or even make a career out of it. Its important to understand chemistry if you are studying any of the sciences because all of the sciences involve matter and the interactions between types of matter. Students wanting to become doctors, nurses, physicists, nutritionists, geologists, pharmacists, and (of course) chemists all study chemistry. You might want to make a career of chemistry because chemistry-related jobs are plentiful and high-paying. The importance of chemistry wont be diminished over time, so it will remain a promising career path.

Medieval Chivalry Essay -- essays research papers fc

Western Civilization Medieval Chivalry and Knighthood During medieval times knighthood was a class culture, cherished and jealousy guarded by the knightly caste. Knight had the honor of defending the king as well as their country. On the bloody fields of battle a code of chivalry evolved that tempered anger and fury with mercy. It created ways of turning the grim business of fighting into something tolerable, perhaps even acceptable. Chivalry was not only looked upon as a code for war; it was looked upon as a setting for stories of love and romance. Chivalry meant a higher social status as well as recognition. Chivalry as we know it denotes the ideals and practices considered suitable to be a noble. Over time chivalry has been used as the primal word to describe the attitude and actions of men towards women. "The word itself is reminiscent of the milieu in which the ideas connected with it took shape-the aristocratic society of mediaeval France dominated by mounted warriors or chevaliers." From as early as the eleventh century several different sets of ideas represented different standards of chivalric behavior. Over the next four hundred years the concepts of Hanuka, 2 The ideal nobleman developed by and for the feudal class under the influence of changing environments, ideas, political views and economies. The concept of being born into a certain class in society was a great part of medieval life. This concept of the class system was based on the land ownership and duties that were owed to other people. The knights were the military supporters of the feudal lords. The knight fought for his lord and if necessary died for him. However, the feudal inheritance was provided only for the eldest son. Younger sons therefore tended to the church or joined groups of knight lacking land. They worked and did their jobs waiting for the opportunity to marry into an estate. There were three methods of becoming a knight. "The most common involved the King or tenant-in-chief conferring the title, known as 'dubbing'. The second method involved religion, the soon to be knight kept a night vigil with his arms on the altar in front of him. He then took a purifying bath, heard Mass and had his spurs put on it. The dubbing then followed with a formal sermon and a sword. The third method involved the readings of a service Benedictio Novi Militis. Hanuka, 3... ...; Works Cited Barber, Richard.

Henry V Represents the More Selfish Side

â€Å"Henry V represents the more selfish side of Kingship† Shakespeare creates two ways for the audience to see King Henry V. One way is King Henry being a gracious, caring king. The other way Shakespeare has created for the audience to see is King Henry being a selfish, cold king. Many people do believe that King Henry V is depicted as a selfish and cold hearted king who is not concerned or worried about the human cost of war. I believe the contrary. I believe that King Henry V was a loving and caring King towards the people of his country and family.In Act one scene one (line 39-40) Canterbury describes King Henry V as a thoughtful and devout ruler. â€Å"Hear him but reason in divinity, and all-admiring, with and inward wish, you would desire the king were made a prelate. † This indicates that the people of his country appreciate him and sees him as a considerate and divine king. King Henry V always tryst to stand by his Kingdom and protect it however he can. As he notices the assassination plot of Scroop, Cambridge and Gray in act one scene two (line 76-79) he sentences them to death.Though Scroop, Cambridge and Gray are his friends he still stands by his Kingdom to keep it safe. â€Å"The mercy that quick in us but late By your own counsel is suppress’d and kill’d. You must not dare for shame to talk of mercy, for your own reasons turn into your bosoms,† In act four King Henry V is sharing the concerns of the common soldiers. His bravery and courage are reflected in his soldiers; especially after his speech about ‘St Crispin’s Day’ In act four scene 3 (line 18-67). This day is called the feast of crispian. He that outlives this day and comes safe home†¦ He shall see this day and live old age, will yearly on the vigil feast his neighbors, And say ‘tomorrow is saint crispian†¦Ã¢â‚¬  This shows that King Henry V is heroic to his soldiers and gives them faith and courage by this speech sh owing high spirits and strength. After the Battle (Act 5 scene 2) King Henry V proposes to princess Katharine of France.Though he has the power to force her to marry him, he decides to try to convince her by admiring her and telling her that she will have a good life with him as a husband. â€Å"But in loving me you should love the friend of France†¦ I will have it all mine; and, Kate, when France is mine and I am yours, then yours is France, and you are mine. † (line 167-169) Overall I think that King Henry V is a caring King with courage and a lot of Strength. He stands by his country and supports and protects it with all his faith and strength .

The Impact of Science and Technology Essay

Advancements in science and technology have facilitated lifestyles much more comfortably with many substantial achievements in these decades. The launch of satellites into the earth orbit for communication purpose have brought people closer together regardless of the regions where they live in. The birth of electricity was the important milestone in the history of research and development in science and technology which led to the creation of many useful electronic devices and equipment to facilitate human activities. Hence, it is no doubt that the impact of science and technology regarding satellite communication and electricity generation has been good for everyone. This positive impact will be evaluated in the aspects of the development of friendly environmental forms of transportation, the growth of rural electrification in Third World countries and the enhancement of quality of life through medicine. The useful invention of electricity generation affects positively to the health of communities in terms of the development of friendly environmental forms of transportation. Carbon dioxide emissions affect negatively the health of communities and are the main cause of greenhouse gas which leads to global climate change. Half of global carbon dioxide is emitted by the burning of fossil fuel used by transportation (cited in Jà ¤rvinen, Orton and Nelson 2012). The creations of electric vehicles such as electric cars and electric trains are essential to contribute to downsizing the harmful carbon dioxide emissions. Jà ¤rvinen, Orton and Nelson (2012) argued that globally, there is a long term transportation policy which shifts gradually away from using liquid fossil fuels towards using electricity. ‘Electricity as a transportation fuel is a win-win for the economy and for the environment’ (Close-Up Media 2012, p.1), electricity is cheaper about 75 percent regarding fuel expense than gas or diesel and ‘electric transportation is much cleaner than gas or diesel fueled transportation, in terms of carbon and other pollutants’ (ibid, p.1), were concluded. It is argued that electricity which is used in electric vehicles is generated by burning coal, thus it also releases a large amount of carbon dioxide. Rigden (2002) stated that the carbon dioxide from burning fossil fuel to energy technology which links to global warming is undeniable. Although this carbon dioxide may be emitted from electricity  generation, it is not significant compared with the carbon dioxide emissions from internal combustion engine vehicles. The face is that electric vehicles will be able to mitigate per-kilometre ‘CO2 emissions by 33% in 2010, and 43–56% by 2030â€℠¢ (Wu et al. 2012, p. 549), so this compares favourably with the high emissions of internal combustion engine vehicles. It is no doubt that the generation of electricity provides beneficial to evolutions of various forms of transport which are friendly with the environment and therefore they benefit the people’s health. The generation of electricity also benefits strongly to the growth of rural electrification in Third World countries. The electrification brings the convenient life to people; especially the inhabitants in the remote regions of the developing nations who have the slow chance to approach electricity. There was the significant increase in the rate of rural electrification about fifteen times within 25 years from 1976 to 2000 which has been paralleled with the remarkable decrease in the incidence of poverty about 6 times in the same period in Tunisia (Chaieb and Ounalli 2001). The electrification which presented its advantages in the education with more electric lights instead of candle and kerosene lamps for school-age children to avoid eyes problems, in the health care with more electric medical equipment for patients to be cured and prevent diseases has been indicated in Tunisia (Chaieb and Ounalli 2001). The conclusion is that ‘national household electrification programme’ in South Africa has the good implication on the health and the quality of life of women in the remote areas in mitigation air pollution, enhancement health and saving time (Mathee and Wet 2001, p. 20). It is asserted that the natural resources such as oil, gas and coal which are used to generate electricity are limited; they are unable endless to meet the increasing demand of electricity in the rural areas. Whilst it may be true that these natural resources are limited, there are several alternative renewable resources to generate adequate electricity for the remote communities. It is implied that in rural regions, there is no proper infrastructure to generate enough powder for their demands, the renewable sources such as solar energy, wind energy ‘may be the most commercially competitive form of energy’ (Rigden 2002, p. 28). It is advocated that the cost of electricity generation from the onshore wind energy is the cheapest among other renewable sources (Rigden 2002). Hence, it is evident that the commencement  of electricity generation with the renewables resources is really beneficial to rural electrification in the developing countries. The other helpful implications of science and technology regarding satellite communication on people presented through the enhancement of quality of life through medicine. The useful roles of satellite communications to people’s health care is shown by the birth of telemedicine. Telemedicine applies telecommunication technologies to consult, monitor and diagnose patients in public hospitals and remote areas, to supply tele-education for medical personnel, medical interactive videoconference and provide telemedicine for emergency scenes. Foote (1977, p. 173) has reported that there was the remarkable increase in ‘health aide-physcian contact’ and ‘new cases handled by teleconsultation’ in first year of ‘introduction of the satellite link’ for rural health services i n Alaska. It has been inferred that not only the public health care, especially for people in the rural places has been improved but also the performance, proficiency and competence of medical doctors has been upgraded since the Venesat-1 satellite was launched in Venezuela (Acevedo, Varela, and Orihuela 2010). Therefore, people’s health care is well facilitated with the wide coverage of satellites services. Counterpoints, of course, be considered is that it is fairly hard for the Third World countries to apply satellite communication in medicine due to the costly implement of satellites equipment. Technology review (1990) stated that there was a slow approach of the satellite services to isolated places where needed the most. Even though the developing countries cannot launch satellite themselves, they can still receive the sponsor from the developed nations for free satellite educational and medical communications (Technology review 1990). Thus, the innovation of satellite communication supports positively the quality of life of people through medical field regardless of the public or remote areas they live in. In conclusion, it is obvious that the advancements in science and technology regarding satellite communication and electricity generation creates the strongly positive impact on everyone from every region in the world. Despite of few negative effects of science and technology, it is undeniable that the advantages of satellite communication and electricity generation outweigh their disadvantages in terms of the friendly environmental forms of transportation are increasingly invented, the rural electrification in Third World countries is strongly developed and the quality of life through medicine is supportively intensified. Therefore, scientists should make more efforts in research and development in science and technology to generate more useful, outstanding innovations to facility and upgrade quality of life of human being in future. .

Ska Music essays

Ska Music essays Music is one medium through which a generation can express itself. For a generation of suppressed, restless, working-class youths living in early 1960's Jamaica, this voice was a genre of music known as ska. Since its original appearance, ska has resurfaced twice. Ska music has been presented to three generations of fans in three separate "waves." Its humble beginnings lead to one of the most influential styles of music present in the world. By 1962, Jamaica was no longer under British rule. Jamaican culture and music began to reflect the new found optimism in its independence. Since the early 1940's, Jamaica had adopted and adapted many forms of American musical styles. The predominantly black inhabitants of Jamaica took a liking to rhythm and blues music , and with imported American records, "enterprising businessmen attempted to string up small sound systems consisting of radio, turntable, and independent speaker boxes". These portable sound systems provided entertainment at dance halls. Owners of different sound systems competed against each other at the halls. The sound systems were run by two individuals, the deejay and the selector, dressed in "spangled waistcoats, black leather Dracula capes, imitation ermine robes, Lone Ranger masks, and rhinestone-studded crowns" . The deejay job was to introduce each record and to enhance the rhythm of the music! by chanting along with the record. Selectors chose records and used the controls to increase or decrease bass, treble, or volume. Musicians picked up on the elements of the rhythm and blues and combined it with traditional Jamaican mento music. The result was the first wave of ska. Musically, ska is "a shuffle-rhythm close to mento but even closer to the backbeat of the r&b, with the accent on the second and fourth beats, often moving in a 12-bar blues-frame. The afterbeat, strummed by a rhythm guitar or played on the piano . . . came to be charac...

How the Versailles Treaty Contributed to Hitlers Rise

How the Versailles Treaty Contributed to Hitler's Rise In 1919, a defeated Germany was presented with peace terms by the victorious powers of World War I. Germany wasn’t invited to negotiate and was given a stark choice: sign or be invaded. Perhaps inevitably, given the years of mass bloodshed German leaders had caused, the result was the Treaty of Versailles. But from the start, the terms of the treaty caused anger, hate, and revulsion across German society. Versailles was called a diktat, a dictated peace. The German Empire from 1914 was split up, the military carved to the bone, and huge reparations demanded. The treaty caused turmoil in the new, highly troubled Weimar Republic, but, although Weimar survived  into the 1930s, it can be argued that key provisions of the Treaty contributed to the rise of Adolf Hitler. The Treaty of Versailles was criticized at the time by some voices among the victors, including economists such as John Maynard Keynes. Some claimed the treaty would simply delay a resumption of war for a few decades, and when Hitler rose to power in the 1930s and started a  second world war, these predictions seemed prescient. In the years after World War II, many commentators pointed to the treaty as being a key enabling factor. Others, however, praised the Treaty of Versailles and said the connection between the treaty and the Nazis was minor. Yet Gustav Stresemann, the best-regarded politician of the Weimar era, was constantly trying to counter the terms of the treaty and restore German power. The Stabbed in the Back Myth At the end of World War I, the Germans offered an armistice to their enemies, hoping negotiations could take place under the Fourteen Points of Woodrow Wilson. However, when the treaty was presented to the German delegation, with no chance to negotiate, they had to accept a peace that many in Germany saw as arbitrary and unfair. The signatories and the Weimar government that had sent them were seen by many as the November Criminals. Some Germans believed this outcome had been planned. In the later years of the war, Paul von Hindenburg and Erich Ludendorff had been in command of Germany. Ludendorff called for a peace deal but, desperate to shift the blame for defeat away from the military, he handed power to the new government to sign the treaty while the military stood back, claiming it hadn’t been defeated but had been betrayed by the new leaders. In the years after the war, Hindenburg claimed the army had been stabbed in the back. Thus the military escaped blame. When Hitler rose to power in the 1930s, he repeated the claim that the military had been stabbed in the back and that surrender terms had been dictated. Can the Treaty of Versailles be blamed for Hitlers rise to power? The terms of the treaty, such as Germanys acceptance of blame for the war, allowed myths to flourish. Hitler was obsessed with the belief that Marxists and Jews had been behind the failure in World War I and had to be removed to prevent failure in World War II. The Collapse of the German Economy It can be argued that Hitler may not have taken power without the massive economic depression that struck the world, including Germany, in the late 1920s. Hitler promised a way out, and a disaffected populace turned to him. It can also be argued Germany’s economic troubles at this time were due- at least in part- to the Treaty of Versailles. The victors in World War I had spent a colossal sum of money, which had to be paid back. The ruined continental landscape and economy had to be rebuilt. France and Britain were facing huge bills, and the answer for many was to make Germany pay. The amount to be repaid in reparations was huge, set at $63 billion at the time, later reduced to $33 billion and finally $28 billion. But just as Britains effort to make American colonists pay for the French and Indian War backfired, so did reparations. It wasn’t the cost that proved the problem since reparations had been all but neutralized after the 1932 Lausanne Conference, but the way the German economy became massively dependent on American investment and loans. This was fine when the American economy was surging, but when it collapsed during the Great Depression Germany’s economy was ruined as well. Soon six million people were unemployed, and the populace became drawn to right-wing nationalists. It’s been argued that the economy was liable to collapse even if America’s had stayed strong because of Germanys problems with foreign finance. It also has been argued that leaving pockets of Germans in other nations via the territorial settlement in the Treaty of Versailles was always going to lead to conflict when Germany tried to reunite everyone. While Hitler used this as an excuse to attack and invade, his goals of conquest in Eastern Europe went far beyond anything that can be attributed to the Treaty of Versailles. Hitlers Rise to Power The Treaty of Versailles created a small army full of monarchist officers, a state within a state that remained hostile to the democratic Weimar Republic and that succeeding German governments didn’t engage with. This helped create a power vacuum, which the army tried to fill with  Kurt von Schleicher before backing Hitler. The small army left many ex-soldiers unemployed and ready to join the warring on the street. The Treaty of Versailles contributed greatly to the alienation many Germans felt about their civilian, democratic government. Combined with the actions of the military, this provided rich material Hitler used to gain support on the right. The treaty also triggered a process by which the German economy was rebuilt based on U.S. loans to satisfy a key point of Versailles, making the nation especially vulnerable when the Great Depression hit. Hitler exploited this, too, but these were just two elements in Hitler’s rise. The requirement for reparations, the political turmoil over dealing with them, and the rise and fall of governments, as a result, helped keep the wounds open and gave right-wing nationalists fertile ground to prosper.
