- 2121: Oxygen
- ... in which combustible liquids are produced from coal will become increasingly important as petroleum resources become further depleted. Production Oxygen is conveniently produced in the laboratory by heating mercuric oxide or potassium chlorate to moderately high temperatures. The production from mercuric oxide is the method that was employed by Joseph Priestley, and the production from the potassium chlorate method commonly used by students in today's laboratories. Oxygen is liberated when ... the violent hydrogen-oxygen reaction discussed previously. When a current is passed through water the liquid is decomposed at the electrodes. This method is also used to produce oxygen on a commercial scale when a high-purity product is desired. The more economical, and therefore preferred, method for the commercial production of oxygen is the liquefaction and distillation of air. The air is cooled until it liquefies, principally by being made ... astronauts is a source of oxygen gas. Similarly, persons ill with respiratory diseases that interfere with normal respiration, such as pneumonia and emphysema, are often kept in OXYGEN TENTS and HYPERBARIC CHAMBERS, the latter administering high-pressure oxygen, may be used to treat a variety of ailments. Important Compounds In the realm of inorganic chemistry there is a very large number of oxygen-containing compounds. There are very few elements ...

- ... industry and agriculture within the United States, and between the U.S. and Europe. This imbalance of wealth created an unstable economy. The excessive speculation in the late 1920's kept the stock market artificially high, but eventually lead to large market crashes. These market crashes, combined with the maldistribution of wealth, caused the American economy to capsize. The "roaring twenties" was an era when our country prospered tremendously. However, the ... business world, the Federal Reserve Board kept the rediscount rate low. The federal government favored the new industries as opposed to agriculture. During World War I the federal government had subsidized farms, and payed absurdly high prices for wheat and other grains. The federal government had encouraged farmers to buy more land, to modernize their methods with the latest in farm technology, and to produce more food. This made sense during ... distribution of wealth was tariff policy of the United States. The United States had traditionally placed tariffs on imports from foreign countries in order to protect American business. However these tariffs reached an all-time high in the 1920's and early 1930's. Starting with the Fordney-McCumber Act of 1922 and ending with the Hawley-Smoot Tariff of 1930, the United States increased many tariffs by 100% or ...
- 2123: America and the Computer Industry
- ... for over a half-century, but its ancestors have been around for 2000 years. However, only in the last 40 years has it changed the American society. >From the first wooden abacus to the latest high-speed microprocessor, the computer has changed nearly every aspect of peopleΥs lives for the better. The very earliest existence of the modern day computerΥs ancestor is the abacus. These date back to almost 2000 years ... the military. New weapons systems were produced which needed trajectory tables and other essential data. In 1942, John P. Eckert, John W. Mauchley, and their associates at the University of Pennsylvania decided to build a high-speed electronic computer to do the job. This machine became known as ENIAC, for "Electrical Numerical Integrator And Calculator". It could multiply two numbers at the rate of 300 products per second, by finding the ... wire it to perform whatever task he wanted the computer to do. It was, however, efficient in handling the particular programs for which it had been designed. ENIAC is generally accepted as the first successful high-speed electronic digital computer and was used in many applications from 1946 to 1955 (Dolotta, 50). Mathematician John von Neumann was very interested in the ENIAC. In 1945 he undertook a theoretical study of ...
- 2124: Constructual Building Material
- ... of iron's impurities and the addition of desirable alloying elements. Steel was first made by cementation, a process of heating bars of iron with charcoal so that the surface of the iron acquired a high carbon content. The bars were then fused together, yielding a metal harder and stronger than the individual bars but lacking uniformity in these properties. The crucible method, consisting of melting iron together with other substances in a crucible, is one of the costlier steelmaking processes, employed only for making special steels (e.g., the famous blades of Damascus). Steel is often classified by its carbon content: a high-carbon steel is hard and brittle; low- or medium-carbon steel can be welded and tooled. Alloy steels, now the most widely used, contain one or more elements that give them special properties. Aluminum steel is smooth and has a high tensile strength. Chromium steel is used in automobile and airplane parts because of its hardness, strength, and elasticity. Nickel steel is the most widely used of the alloys; it is nonmagnetic and has the ...
- 2125: Personal Bond With My Friends During Tennis Camp
- Personal Bond With My Friends During Tennis Camp During the summer months following my seventh grade school year, I was involved in tennis camp activities with two of my closest friends, Suzanne and Erin. This was the first time that we were able to get to know each other better away from school since we did not have any classes together that year. Even though we were good friends, I had never felt a sense of camaraderie with either of them because they participated in sports, while I was involved in academics and other school activities. Not having had any paritcular interest in sports before the summer camp session, it was surprising that I became completely enthralled with the sport of tennis. Tennis proved to be my initial experience ...
- 2126: What The United States Can Learn From Japan
- ... sectors of the economy by focusing R&D, subsidies, and tax incentives to specific industries that the government wants to promote. The United States could adopt some of these industrial policies to help foster emerging high tech businesses and help existing U.S. business remain competitive with East Asia. In Japan the government both during the Meiji period and the post World War II period followed a policy of active, sector ... steel production, and textiles. The Meiji leaders took taxes levied on agriculture to fund the development of these new industries. Following World War II Japanese industries used this same strategic industrial policy to develop the high-tech, steel, and car industries that Japan is known for today. Some American industries are currently heavily supported by the government through subsidies and tax breaks to farmers, steel producers, and other industries that have ... are predominantly low-tech industries. But this economic policy of the U.S. is almost a complete reversal of the economic policies of Japan and the Four Little Tigers; instead of fostering new businesses and high tech industry it supports out of date and low tech firms who have political clout. The existing economic policy of the United States fails to help high tech businesses develop a competitive advantage on ...

- ... 3) The value and depth of film libraries, which extend a film's life cycle and gererate revenues far into the future. Key Problems Cost- Film profits are rare and difficult to measure. There are high promotional and marketing costs which include fees paid to exhibitors, distributions fees, overheads, interset and expenses ( paid usually to studios distributors). These combined costs greatly reduce the revenue sream flowing to the producer and net ... If the studio is a "major" that is not already diversified, the competition and cost to do so would be significant factor. Barriers to entry for independents- The most obvious barrier to entry is the high cost of acquisition. Larger studios owe their survival to ample resources, which afford them the ability to weather box office disasters. Small studios would not necessarily be able to survive box office failures. Major studios ... Any major changes in the market? *** (The Movie Industry by James Jaeger). Increased foreign demand for U.S movies is reflected in the fact that recent export sales to foreign markets hit an all time high in 1997. The European foreign market accounts for 56% of global revenues generated by English language. One of the most attractive markets is centered around the Far East, Japan being the largest. Focus on ...

- 2129: Industry Production
- ... workshop level, as is seen by the small workforce in each production unit. On the other hand, the small number of large companies is explained by increased concentration, at that level also indicated by the high number of employees. There is only a limited number of cooperative companies (food sector and the transformation of agricultural products), while large companies tend to become multinational. The presence of companies with foreign capital monopolizing ... steel industry, itself conditioned by the importation of raw materials such as ores, scrap iron and coal. Membership of ECSC enabled the Italian steel industry, which had installed the integral processing cycle, to attain extremely high levels of production thus satisfying increasingly greater domestic demand, such as that of the engineering industry, as well as the export market. Following plant reconversion steel and metal production is now stagnating due to the ... of circa 50 m, while in the marginal belt at the foot of the pre-Alps and the Alps it exceeds 200 m. This is the point at which it is possible to distinguish a high (gravel and sand) from a low (mainly mud and clay) plain, separated by a row of springs that have had an important influence in the development of the plain's agricultural economy (cultivation of ...

- ... years old, leaving Emily and her five siblings, Maria, Elizabeth, and Charlotte, Anne, and Branwell to the care of the dead woman s sister. Emily, Maria, Elizabeth, and Charlotte were sent to Cowan, a boarding school, in 1824. The next year while at school Maria and Elizabeth came home to die of tuberculosis, and the other two sisters were also sent home. Both spent the next six years at home, where they picked up what education they could. In 1835, Charlotte became a teacher at the school at Roe Head and Emily joined her as a student. After three months Charlotte sent her home again, afraid that Emily was extremely homesick from her beloved moors. For a short time in 1837 ...
