Evading Loneliness Essay

In A Streetcar Named Desire, the author Tennessee Williams chooses to depict the downfall of Blanche through her desire to evade loneliness. Throughout the text, Blanche faces loneliness, yet she cannot fill her desire. After the loss of her family estate referred to as, Belle Reve, is officially rendered without family. Having lost her wealth and all her family, she develops the inability to be honest with anyone interested in her. Blanches true desire to evade loneliness causes her downfall. The story develops when Blanche loses Belle Reve. She had been living there with her young husband, Allan. Her desire to evade loneliness develops when her husband commits suicide. In scene 9 Blanche is talking to Mitch when she suddenly reminisces about the tragic night. She says, â€Å"’The ‘’’Varsouviana’†! The polka tune they were playing when Allan—Wait! [A distant revolver shout is heard. Blanche is relieved.] There now the shot! It always tops after that†¦Ã¢â‚¬ Ã¢â‚¬â„¢ (Norton 1853). Blanche is obviously still tenderhearted about the loss and the relief that it stopped allows readers to see that she wants Mitch to be her barrier from loneliness. If they were to marry Blanche would not fear being alone. Along with Allan, Blanche suffers the loss of multiple family members. To deal with her losses, as well as, gain company she leaves Belle Reve for New Orleans to stay with her sister, Stella. Blanche’s desire to evade loneliness is clearly shown when she is given directions to her sister’s townhome, â€Å"†¦take a street—car named Desire, and then transfer to one named Cemeteries†¦.† (Norton1805.) Williams offers the reader a chance to foreshadow that her desire will lead to her downfall. Blanche is very quick, when she sees her sister, to ask,† What are you doing in a place like this?† (Norton 1808), with a patronizing tone that does not fit the situation considering she is planning to stay with Stella. Clearly indentifying Blanche’s reasoning behind her visit is for the company of her sister. Furthermore, with the inability to be truthful Blanche rejects any hopes of filling her desire. Clearly stated by Mitch,† Lies, lies, inside and out, all lies.† (Norton 1855), this showing that the man that was on the verge of her rescue was pushed by lies. Death is the opposite of desire to sum up Blanche DuBois. Downfall is brought upon herself when she losses the family estate and she chooses to lie about herself to others. Tennessee Williams craftily depicts Blanche’s downfall through her desire to evade loneliness. Work Cited Williams, Tennessee A Streetcar Named Desire. The Norton Introduction to Literature.

Animal Nutrition: Distinguish Macronutrients and Micronutrients Essay

There are seven major classes of nutrients: carbohydrates, fats, fiber, minerals, protein, vitamin, and water. These nutrient classes can be categorized as either macronutrients (needed in relatively large amounts) or micronutrients (needed in smaller quantities). The macronutrients are carbohydrates, fats, fiber, proteins, and water. The micronutrients are minerals and vitamins. The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some of the structural material can be used to generate energy internally, and in either case it is measured in joules or calories (sometimes called â€Å"kilocalories† and on other rare occasions written with a capital C to distinguish them from little ‘c’ calories). Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram.,[1] though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons. A third class dietary material, fiber (i.e., non-digestible material such as cellulose), seems also to be required, for both mechanical and biochemical reasons, though the exact reasons remain unclear. Molecules of carbohydrates and fats consist of carbon, hydrogen, and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose, fructose, galactose) to complex polysaccharides (starch). Fats are triglycerides, made of assorted fatty acid monomers bound to glycerolbackbone. Some fatty acids, but not all, are essential in the diet: they cannot be synthesized in the body. Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen. The fundamental components of protein are nitrogen-containing amino acids, some of which areessential in the sense that humans cannot make them internally. Some of the amino acids are convertible (with the expenditure of energy) to glucose and can be used for energy production just as ordinary glucose. By breaking down existing protein, some glucose can be produced internally; the remaining amino acids are discarded, primarily as urea in urine. This occurs normally only during prolonged starvation.

They constitute a large part of foods such as rice, noodles, bread, and other grain-based products. Monosaccharides contain one sugar unit, disaccharides two, and polysaccharides three or more. Polysaccharides are often referred to as complex carbohydrates because they are typically long multiple branched chains of sugar units. The difference is that complex carbohydrates take longer to digest and absorb since their sugar units must be separated from the chain before absorption. The spike in blood glucose levels after ingestion of simple sugars is thought to be related to some of the heart and vascular diseases which have become more frequent in recent times. Simple sugars form a greater part of modern diets than formerly, perhaps leading to more cardiovascular disease. The degree of causation is still not clear, however. Fat A molecule of dietary fat typically consists of several fatty acids (containing long chains of carbon and hydrogen atoms), bonded to a glycerol. They are typically found as triglycerides (three fatty acids attached to one glycerol backbone). Fats may be classified as saturated or unsaturateddepending on the detailed structure of the fatty acids involved. Saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded, so their molecules have relatively fewer hydrogen atoms than a saturated fatty acid of the same length. Unsaturated fats may be further classified as monounsaturated (one double-bond) or polyunsaturated (many double-bonds). Furthermore, depending on the location of the double-bond in the fatty acid chain, unsaturated fatty acids are classified as omega-3 or omega-6 fatty acids. Trans fats are a type of unsaturated fat with trans-isomer bonds; these are rare in nature and in foods from natural sources; they are typically created in an industrial process called (partial) hydrogenation. Many studies have shown that unsaturated fats, particularly monounsaturated fats, are best in the human diet. Saturated fats, typically from animal sources, are next, while trans fats are to be avoided. Saturated and some trans fats are typically solid at room temperature (such as butter orlard), while unsaturated fats are typically liquids (such as olive oil or flaxseed oil). Trans fats are very rare in nature, but have properties useful in the food processing industry, such as rancid resistance.[citation needed] Essential fatty acids Most fatty acids are non-essential, meaning the body can produce them as needed, generally from other fatty acids and always by expending energy to do so. However, in humans at least two fatty acids are essential and must be included in the diet. An appropriate balance of essential fatty acids -— omega-3 and omega-6 fatty acids -— seems also important for health, though definitive experimental demonstration has been elusive. Both of these â€Å"omega† long-chain polyunsaturated fatty acids are substrates for a class of eicosanoids known as prostaglandins, which have roles throughout the human body. They are hormones, in some respects. The omega-3 eicosapentaenoic acid (EPA), which can be made in the human body from the omega-3 essential fatty acid alpha-linolenic acid (LNA), or taken in through marine food sources, serves as a building block for series 3 prostaglandins (e.g. weakly inflammatory PGE3). The omega-6 dihomo-gamma-linolenic acid (DGLA) serves as a building block for series 1 prostaglandins (e.g. anti-inflammatory PGE1), whereas arachidonic acid (AA) serves as a building block for series 2 prostaglandins (e.g. pro-inflammatory PGE 2). Both DGLA and AA can be made from the omega-6 linoleic acid (LA) in the human body, or can be taken in directly through food. An appropriately balanced intake of omega-3 and omega-6 partly determines the relative production of different prostaglandins: one reason a balance between omega-3 and omega-6 is believed important for cardiovascular health. In industrialized societies, people typically consume large amounts of processed vegetable oils, which have reduced amounts of the essential fatty acids along with too much of omega-6 fatty acids relative to omega-3 fatty acids. The conversion rate of omega-6 DGLA to AA largely determines the production of the prostaglandins PGE1 and PGE2. Omega-3 EPA prevents AA from being released from membran es, thereby skewing prostaglandin balance away from pro-inflammatory PGE2 (made from AA) toward anti-inflammatory PGE1 (made from DGLA). Moreover, the conversion (desaturation) of DGLA to AA is controlled by the enzyme delta-5-desaturase, which in turn is controlled by hormones such as insulin (up-regulation) and glucagon (down-regulation). The amount and type of carbohydrates consumed, along with some types of amino acid, can influence processes involving insulin, glucagon, and other hormones; therefore the ratio of omega-3 versus omega-6 has wide effects on general health, and specific effects on immune function and inflammation, and mitosis (i.e. cell division). Good sources of essential fatty acids include most vegetables, nuts, seeds, and marine oils,[2] Some of the best sources are fish, flax seed oils, soy beans, pumpkin seeds, sunflower seeds, and walnuts. Fiber Dietary fiber is a carbohydrate (or a polysaccharide) that is incompletely absorbed in humans and in some animals. Like all carbohydrates, when it is metabolized it can produce four calories (kilocalories) of energy per gram. But in most circumstances it accounts for less than that because of its limited absorption and digestibility. Dietary fiber consists mainly of cellulose, a large carbohydrate polymer that is indigestible because humans do not have the required enzymes to disassemble it. There are two subcategories: soluble and insoluble fiber. Whole grains, fruits (especiallyplums, prunes, and figs), and vegetables are good sources of dietary fiber. Fiber is important to digestive health and is thought to reduce the risk of colon cancer.[citation needed] For mechanical reasons it can help in alleviating both constipation and diarrhea. Fiber provides bulk to the intestinal contents, and insoluble fiber especially stimulates peristalsis — the rhythmic muscular contractions of the intestines which move digesta along the digestive tract. Some soluble fibers produce a solution of high viscosity; this is essentially a gel, which slows the movement of food through the intestines. Additionally, fiber, perhaps especially that from whole grains, may help lessen insulin spikes and reduce the risk of type 2 diabetes. Protein Proteins are the basis of many animal body structures (e.g. muscles, skin, and hair). They also form the enyzmes which control chemical reactions throughout the body. Each molecule is composed of amino acids which are characterized by inclusion of nitrogen and sometimes sulphur (these components are responsible for the distinctive smell of burning protein, such as the keratin in hair). The body requires amino acids to produce new proteins (protein retention) and to replace damaged proteins (maintenance). As there is no protein or amino acid storage provision, amino acids must be present in the diet. Excess amino acids are discarded, typically in the urine. For all animals, some amino acids are essential (an animal cannot produce them internally) and some are non-essential (the animal can produce them from other nitrogen-containing compounds). About twenty amino acids are found in the human body, and about ten of these are essential, and therefore must be included in the diet. A diet that contains adequate amounts of amino acids (especially those that are essential) is particularly important in some situations: during early development and maturation, pregnancy, lactation, or injury (a burn, for instance). A complete protein source contains all the essential amino acids; an incomplete protein source lacks one or more of the essential amino acids. It is possible to combine two incomplete protein sources (e.g. rice and beans) to make a complete protein source, and characteristic combinations are the basis of distinct cultural cooking traditions. Sources of dietary protein include meats, tofu and other soy-products, eggs, grains, legumes, and dairy products such as milk and cheese. A few amino acids from protein can be converted into glucose and used for fuel through a process called gluconeogenesis; this is done in quantity only during starvation. The amino acids remaining after such conversion are discarded. Vitamins As with the minerals discussed above, some vitamins are recognized as essential nutrients, necessary in the diet for good health. (Vitamin D is the exception: it can alternatively be synthesized in the skin, in the presence of UVB radiation.) Certain vitamin-like compounds that are recommended in the diet, such as carnitine, are thought useful for survival and health, but these are not â€Å"essential† dietary nutrients because the human body has some capacity to produce them from other compounds. Moreover, thousands of different phytochemicals have recently been discovered in food (particularly in fresh vegetables), which may have desirable properties including antioxidant activity (see below); experimental demonstration has been suggestive but inconclusive. Other essential nutrients not classed as vitamins include essential amino acids (see above),choline, essential fatty acids (see above), and the minerals discussed in the preceding section. Vitamin deficiencies may result in disease conditions: goitre, scurvy, osteoporosis, impaired immune system, disorders of cell metabolism, certain forms of cancer, symptoms of premature aging, and poor psychological health (including eating disorders), among many others.[6] Excess of some vitamins is also dangerous to health (notably vitamin A), and for at least one vitamin, B6, toxicity begins at levels not far above the required amount. Deficiency or excess of minerals can also have serious health consequences. Water About 70% of the non-fat mass of the human body is made of water[7] . Analysis of Adipose Tissue in Relation to Body Weight Loss in Man. Retrieved from Journal of Applied To function properly, the body requires between one and seven liters of water per day to avoid dehydration; the precise amount depends on the level of activity, temperature, humidity, and other factors.[citation needed] With physical exertion and heat exposure, water loss increases and daily fluid needs will eventually increase as well. It is not fully clear how much water intake is needed by healthy people, although some experts assert that 8–10 glasses of water (approximately 2 liters) daily is the minimum to maintain proper hydration.[8] The notion that a person should consume eight glasses of water per day cannot be traced to a credible scientific source.[9] The effect of, greater or lesser, water intake on weight loss and on constipation is also still unclear.[10] The original water intake recommendation in 1945 by the Food and Nutrition Board of the National Research Council read: â€Å"An ordinary standard for diverse persons is 1 milliliter for each calorie of food. Most of this quantity is contained in prepared foods.†[11] The latest dietary reference intake report by theUnited States National Research Council recommended, generally, (including food sources): 2.7 liters of water total for women and 3.7 liters for men.[12] Specifically, pregnant and breastfeeding women need additional fluids to stay hydrated. According to the Institute of Medicine—who recommend that, on average, women consume 2.2 litres and men 3.0 litres—this is recommended to be 2.4 litres (approx. 9 cups) for pregnant women and 3 litres (approx. 12.5 cups) for breastfeeding women since an especially large amount of fluid is lost during nursing.[13] For those who have healthy kidneys, it is somewhat difficult to drink too much water,[citation needed] but (especially in warm humid weather and while exercising) it is dangerous to drink too little. People can drink far more water than necessary while exercising, however, putting them at risk of water intoxication, which can be fatal. In particular large amounts of de-ionized water are dangerous. Normally, about 20 percent of water intake comes in food, while the rest comes from drinking water and assorted beverages (caffeinated included). Water is excreted from the body in multiple forms; including urine and feces, sweating, and by water vapor in the exhaled breath.

Regional Economic Cooperation Essay

One of the most important developments in the world trade system in the 1990s has been the emergence of regional cooperation. The end of the Cold War reduced political tensions between countries in Asia as well as globalizing production processes and increasing vertical integration. Cities like Bangkok, Kuala Lumpur, and Singapore have been lifting their populations out of poverty in part through cooperative arrangements with neighboring countries. Transnational economic zones have utilized the different endowments of the various countries of East Asia, exploiting cooperative trade and development opportunities. Transfer of technology and manufacturing between nations has allowed them to develop sequentially. Information technology has improved linkages between economies and put remote regions in contact with the world. The private sector provides capital for investment; the public sector provides infrastructure, fiscal incentives, and the administrative framework to attract industry. Regional cooperation is now considered the means of enhancing economic development and providing economic security within the regions. Trade among ASEAN members accounted for more than 23% of all trade by member nations in 1994, topping that of any of the group’s major trading partners. Singapore has concentrated on becoming the technology center for Southeast Asia, sending labor-intensive operations to low-cost neighboring countries like Malaysia and Indonesia in special mutual cooperative trade and development arrangements known as growth triangles or growth polygons. The Southern Growth Triangle, also known as SIJORI (Singapore, the Johore state of Malaysia, and Riau Province of Indonesia), was formed in 1989 and covers a population of about 6 million people. It attracted $10 billion in private sector investments during its first five years. Such regional economic cooperation has occurred in other Asian regions as well, spurring economic development. Growth triangles are expected to be a continued driving force for growth in Asian economies throughout the 1990s. Four growth triangles have been established since 1989, involving parts of 11 countries. There are currently eight growth polygons in East and Southeast Asia, with additional triangles being planned. For example, Cambodia, Laos, Myanmar, Thailand, Vietnam, and China’s Yunnan Province have been discussing ways to develop the Mekong area since 1992. Regional cooperation provides a competitive model to attract investment and technology. According to the secretary general of ASEAN, Ajit Singh, â€Å"These growth areas will have to be flexible to change where necessary, innovative, and always attentive to the needs of the investors and the businessmen. They also have to be aware that they are competing with much larger countries such as China and India, whose capacities for attracting investors are much greater than their own† (Kruger 1996, 17). Asian capital markets are now watching the global economy, and large companies recognize their need to be involved in this fastest growing region in the world. The growth triangles typically group remote regions of the nations involved in an effort to exploit complementary assets within the groupings. For example, the Tumen Delta triangle integrates the capital and technology of Japan and the Republic of Korea with the natural resources of Russia and North Korea (i. e. , the People’s Democratic Republic of Korea) and the labor and agricultural resources of China. The governments of Brunei, East and West Kalimantan, and North Sulawesi of Indonesia; Sabah, Sarawak, and Labuan in Malaysia; and Mindanao and Palawan in the Philippines have given priority to expanding air and shipping routes within the East ASEAN Growth Area, another polygon. Where all parts of the polygon are at similar levels of development, growth is expected to be slower. Singapore has provided capital and technology for developments in Malaysia to support SIJORI. Thailand is expected to provide capital and experience in developing the Mekong polygon. It will encompass a population of over 400 million people offering low wages, rents, and land costs. The Southern China Growth Triangle The Southern China Growth area comprises Hong Kong, Taiwan, and the southern provinces of China (Thant et al. 1994). Because China lags behind Taiwan and Hong Kong considerably in economic development and has a very large population, growth in this triangle has enormous potential. Establishment of this triangle was spurred by market forces and private sector initiatives rather than by policy coordination among the countries. However, government policies have supported the economic links that were instituted. The PRC’s economic reforms and open door policy initiated in 1978 laid the foundation for economic success in Guangdong and Fujian provinces. Establishment of China’s first Special Economic Zone (SEZ) in 1980 provided for tax concessions, expanded land use rights, and simplified procedures for foreign investment. Policies for land use, finance, and trade were designed to reduce transaction costs and to provide greater access to the domestic as well as the world market. Policies formulated within the SEZs themselves have been even more liberal than those in other parts of the triangle. For China, the triangle has provided exports, foreign exchange, and employment as well as access to the larger global economy. Rapid economic growth and higher incomes have occurred in Guangdong and Fujian Provinces with materials and components from Taiwan’s manufacturing sectors and the support of Hong Kong’s advanced services sector. Geographical proximity and common language are the most compelling factors for capital to move across the border from Hong Kong into Guangdong Province, or for investment to flow across the Formosa Strait from Taiwan to Fujian Province. Cantonese is a Chinese dialect spoken in both Hong Kong and Guangdong, while Fujianese is spoken in both Taiwan and Fujian. For Hong Kong and Taipei, the triangle has provided a means of implementing structural changes in manufacturing and export patterns at minimal cost. In spite of recent political posturing on the part of China, economic planners in Hong Kong and Taiwan are optimistic that economic logic will continue to drive regional integration. Low-Cost Sourcing As Japanese and U. S firms seek to reduce the cost of their latest innovations, they are outsourcing production to low-cost contract manufacturers. China has a growing number of low-cost parts and components suppliers. With a minimum of overhead and a large pool of low-cost labor in China, there is a growing list of high-quality vendors in China. The continuing miniaturization of products has lead to joint ventures with companies from Japan, the United States, Taiwan, Hong Kong, and other Asian countries. The success of these firms is dependent upon providing competitive value in a timely manner. Low-cost board assembly operations in China utilize the latest SMT equipment required by new computer and telecommunications products. Capital intensity will increase as IC packaging and SMT assembly operations are installed. In the 1980s, Korea and Taiwan provided the first step in the cost reduction chain by providing the most advanced process capabilities. Singapore and Malaysia became additional sources for contract manufacturing with the establishment of global vendors like SCI and Solectron. Today, further cost reduction is possible by moving production to lower cost regions like China and the Philippines. Wong’s Electronics in Hong Kong provides a three-step process for cost reduction that includes low-cost labor, low-cost sourcing, and low-cost production designs. Hong Kong, Thailand, Malaysia, and China are considered the home of lowest-cost manufacturing competitors in the electronics industry today. They offer limited component technology or product design skills, but provide many low-cost suppliers of generic, low-technology components. Since low-cost manufacturing countries generally lack the technologies required to become industry leaders, they must follow the technology trends as quickly as possible. OEM competitors from Taiwan and Singapore are being forced to open branch plants in China or other Southeast Asian countries to produce the most labor-intensive, cost-driven products.

Autism Late Diagnoses Research Proposal Example | Topics and Well Written Essays - 2000 words

Autism Late Diagnoses - Research Proposal Example As a spectrum, it means that the earlier ASD is diagnosed, the better the chances of ensuring that the risk or rate of growth of severity does not increase to certain undesirable levels. However, there continues to be records and reports of late diagnoses of ASD in most children. In relation to the Waldorf approach to developmental stages in children, one would say that if ASD was diagnosed as early as the first stage, it would give medical experts so much hope and room for improving the lives of affected children, especially in terms of their academics. Purpose of the study Based on the background to the study presented above, the researcher seeks to set out a research work that has a purpose of identifying the developmental stages from the perspective of Waldorf approach and link this to Autism Spectrum Disorder late diagnoses. ... This purpose is made with the rationale that as much as autism may be a serious health and psychological problem for children, it should not be the basis for which children should suffer or be left behind in any sense in terms of their normal development as people. This is particularly so when it comes to the academic life of the children. Unfortunately though, the chances of achieving this goal reduces significantly if diagnosis is not made as early enough as possible. While looking at the issue of late diagnosis, the impact of different cultural perspectives will be linked to any possible causes. Aim and objectives To achieve the purpose of the study, an aim has been set for the study, which has further been broken down into specific objectives to signify the specific activities and tasks the researcher should be involved in to achieve the aim. The aim is given as finding the relationship between the developmental stages and autism spectrum disorder late diagnosis. The specific obj ectives to bring about this aim are given as follows. 1. To determine how the developmental stages as given by Waldorf are perceived by different cultures in terms of religious cultures, moderate cultures and liberal cultures 2. To underscore how the perception of developmental stages according to cultural differences help in avoiding or promoting late diagnoses of ASD. 3. To ascertain how children diagnosed with late with ASD can be helped to live healthy integrated lifestyles. Significance of the study Should the aims and objectives set above be achieved, there are a number of benefits that will be derived. In the first place, an understanding on the effect of cultural differences on ASD would help in finding a common perspective grounds for the issue

Leadership and management Assignment Example | Topics and Well Written Essays - 1500 words - 2

Leadership and management - Assignment Example The leadership skills within the organization was very poor which resulted in arise of various issues. There have been various changes taking place in the HR Management as well as the learning and development functions in the HR Department. As the Learning and development manager of the Hospital Trust, I have been asked to prepare a draft report for the HR Director. The report would reflect the changes that have been proposed followed by the impact of the existing culture, hierarchical structure and power of the doctors on the proposed changes. A set of recommendations would also be provided in order to reduce the impact of the above mentioned factors on the proposed changes. ... Moreover the leadership skill in the top management level was poor. Proposed Changes The new CEO of the trust has decided to start a process of radical transformation which would make the trust outward looking by means of high levels of employee engagement and external and internal customer service. The streamlining of the Human Resource management & Development is taking place by using various assessment centres in order to determine the suitability of these new roles within the organization. This required recruitment of new staffs because the existing managers failed to get back their positions in the downsized trust. The HR Department of the Trust was also organized with eight HR professionals among whom four were new in the Trust. The Hr Director was expecting that this time they could provide quality service to the external organizations as well as the internal customers. The learning & development programs within the organization were also being changed. Impact of the Hierarchi cal Structure on the Proposed Change Process The hospital trust has bureaucratic hierarchy which resulted in the poor management process within the organization. According to Ashkanasy, Wilderom and Peterson (2011) the bureaucratic hierarchy has discouraged the innovation and creativity within the organization. Under bureaucratic hierarchy, the Trust faced rigid controls. In such case it is very likely that the organization will find it difficult in adapting to the change process taking place. Thus it will provide resistance to the change process and can make the process slow and time consuming. This would de-motivate the employees and provide stronger resistance to the change. Impact of the present culture on the Proposed Change Process The culture of

Electronic systems Essay Example | Topics and Well Written Essays - 2750 words

Electronic systems - Essay Example These filters produce gain and usually consist only of resistors, capacitors and operational amplifiers. The most common classes of filters that can either be passive or active are the low pass, high pass, band pass, and band stop filters. Ideal low pass filters allow frequencies up to a given limit to pass and attenuate frequencies above that limit. Ideal high pass filters on the other hand, pass frequencies above a specified limit and attenuate those below. Ideal band pass filters allow only a particular band of frequencies to pass and attenuate the remaining frequencies. Ideal band stop filters are the reverse; this class of filters rejects frequencies within a specified band and passes those frequencies outside it. The figure below can be interpreted as first order active filters connected in series. By cascading a 20 dB-gain first order bi-linear filter and another first order bi-linear filter with unity-gain, we can construct a low pass filter whose frequency response is that in Figure 1. When universal filters are cascaded, they form a shaped filter. It is specified that the output signal MUST NOT BE INVERTED. Notice that the transfer function of a bi-linear filter includes a NEGATIVE sign. When two bi-linear filters are cascaded, this eliminates the negative sign thus there is NO NEED for an inverter. From the Transfer Function, where ω denotes the cut-off RADIAN frequency, we can get the cut-off frequency. Since the radian frequency ω =2πf then, . When ω is at the numerator, it denotes a zero and if it is a the denominator, it denotes a pole. A filter is designed based on a given transfer characteristic. An active low pass filter with a gain of 20dB below 10 Hz, 0 dB gain from 160Hz to 48 kHz and -20 dB attenuation above 500 kHz is the subject of this paper. This filter is composed of cascaded components. The transfer characteristic of each of these components is multiplied to obtain the transfer function of the low pass filter. The

Animal rights Essay Example | Topics and Well Written Essays - 1750 words - 1

Animal rights - Essay Example In that regard therefore, awareness on the rights of both human beings and animals need to be brought to the attention of the world. After shedding light as to what right entails, the general public then automatically holds the responsibility of asking why. Here, it is realized that the rights of humans are well found on the basis of the animals rights. It is clear that animal rights establish what is termed as a philosophical stand for the human rights, just as is put clear in Reagan’s theory where he considers life as the body of integrity and argues that it is to be protected. The theory further argues on the study by Tuskegee that the liberty of individual beings has to be protected. The moral theory extends this same protection to all sorts of life forms out in there globe. It beats one’s sense of reason when one tries to consider animals in the category of subject of life. Animals are subject-of-life. In reality, common sense should apply in such instances. Firstly, the behavior of both human beings and animals are the same; human beings and animals have a psychological supportive linkage that explains the similarity between the two. Firstly, the behavior of both humans and animals are the same; human beings and animals have a psychological supportive linkage that explains their similarity. It should be noted that if the rights of human beings are founded in the rights of who they are, then the rights of animals are also rooted in the sense of belonging that the human beings share. It is realized that individuals with experimental mind sets have their warfare aspects directly affects matters of their personal character. This sort of interest tends to override the common sense that supports the real aspect of rights. The science of judgment and ethical evaluations are blinded by the struggle to make an outcome from their internal element of success. In the experiment, world’s scientists have a role to

The Russian Revolution Essay Example | Topics and Well Written Essays - 750 words - 1

The Russian Revolution - Essay Example The Russian revolution can be distributed into two time slots. The first slot covers the timeframe when the Tsars left Russia leaving their autocratic fallacies behind. After the departure of the tsarist power in which the autocratic environment did not allow individuals or organizations to be politically active, the provisional government came into existence in which the DUMA took charge forming the provisional government. The DUMA were the elected middle class that caused the tsar to leave Russia, the tsar were at that time in full control over the bureaucratic setup and the army. The Duma however criticized the tsar’s leadership thus converting the country into a provisional government setup. The formation of the provisional setup was a turnaround for the Russian autocratic setup but this too was coupled with conditions. The ruling out of tsar happened when the tsar left the government in the hands of his wife in order to lead and rally the Russian armies. But rumors, ulter ior motives and mismanagement lead to the departure of tsar, a much appreciated and awaited revolution by all classes of the Russian community. The higher and middle class celebrated as they foresee a more focused and strong war effort; on the other hand the lower class associated good living conditions in the form of better wages and food with the formation of the provisional system. However this form of government was anti-reforms and did not support any political reforms. The continuation of war by Prime Minister Alexander Kennedy was considered a sign of national duty by other socialists as well because it avoided the disintegration of the Russian peasant army. The revolution did not stop at the formation of the provisional government, the parallel ruling of the council of workers worked as the rival of the provisional setup. The Petrograd Soviet or the council of workers and soldiers’ deputies consisted of intellectuals who believed in the revolutionary democracy. They c onsidered themselves the product of the new Russia that is free from the autocratic culture and is democratic in nature. The parallel workings of the national socialists and the provisional government continued but there were many dips in the forms of strikes and protests leading to the second part of the revolution that hit Russia in the month of October 1917. In October, Vladimir Lenin’s Bolshevik party took complete control and all parallel forms of government were removed leaving the socialists in charge of the setup. However this setup too had its ups and downs. The true political revolution requires more than mere changes of the ruling hands and it holds greater benefits than just switching from an autocratic setup to a democratic one. The demands of the political revolution involve formation of the organizations that is revolutionary and different from the workers’ organization. The worker organizations specialize in trade but the revolutionaries take up revolut ion as their profession. Revolutions require a professional setup and people with a professional training into revolutionaries. They are different from the workers in their thought processes, intellect, training, education and in their profession. We have seen that revolutions hit the masses directly who become the parts of it, however, the requirement is of organization who deals with

Communication journal Article Example | Topics and Well Written Essays - 1000 words - 1

Communication journal - Article Example After understanding the values and expectation of the audience, it is a little bit easier to settle on a topic to address. Despite of these tips, I was still confused and nervous since the reception of the audients was still unpredictable. This situation can only be salvaged by visionary leadership skills that turn the weakness or challenges them into strength. Moreover, I was visualizing how I could contain them and what if they make feel and look useless before them. These are some of the conflicts that might emerge during the presentation. The sure way to resolve this situation is to sway the audience to coincide with my points of view particularly through reverse psychology technique. Working in a group often needs a guideline; otherwise, a group will do a lot of nothing. The first thing a group of new members should do is to know each other. This provides an avenue for effective and free communication among members. Secondly, the group should select their leader who will help th em manage the group. The group’s leader will run or direct the fairs of the group. He or she will guide the members through formulation of group’s goals and objectives. Through this process, members will be encouraged to express their opinions and ask the question. After the formulation of these rules, all the group members shall be advised to adhere to the set rules. The Effective Area Social presentations are not quite stressful, unlike business and other official presentations. The social presentation often aims addressing or making a presentation to one’s close acquaintances and friends. Therefore, for my last social presentation I was more relaxed and comfortable with the audience and the topic of discuss. Notably, at some points in the presentation, I freely interacted with the audient has I developed my speech. However, prior to the presentation I was quite uneasy and tensed. Notably, I was afraid of the audience; nonetheless, along the way everything whe n imposing and I build confidence and even enjoyed the presentation. The audience expectation seemed high on my presentation, and I was afraid that the stake was too high to achieve. However, their response to the some funny comments and questions built my confidence and I was convinced me that I achieved or met the expectation of my audience  and they enjoyed my presentation. From the video tape review, it is certain that the beginning of the presentation seemed difficult despite that fact that I was addressing my social friends. In fact, from the video it is apparent that I was unable to look straight into my audience and my eyes were only glued onto my prepared speech. Additionally, there were no body movement and the environment looked tensed. However, middle way everything changed and I got used to the being center stage of my audience the environment became friendly, and I could use gesture and body language to stress some of my points. The videotape presentation review chan ged my perception about presentation completely. From the replays, I learnt that presentations might just be treated as talking to individuals but on geared tunes. Presentation is just another way of sharing once fears and concerns about issues that affect people in the presenter knows them best. Furthermore, the video presentation has only left me practicing on how I will make my other presentations better and as interactive as I

Principles of Brand Extension and its Rationales Essay

Principles of Brand Extension and its Rationales - Essay Example A brand’s name has been identified as a polo shirt together with the ways of how to create its extension and the reasons why creating such. In the economic industry, different strategies are to be considered so that producers will get the attention of the consumers. With every product that producers will provide, a brand name has to be added. A group of ideas on the certain product is what a brand is (Ferree, 2007). Addition to that, according to Webben (as cited in Keller, 2003), brand is defined as products which has a goal to satisfy the consumer’s needs by getting their attention on to it providing them with instructions and the product’s use. After succeeding in the familiarity of the product to the different people, a good strategy should be followed and there comes the brand extension. Brand extension as what Sattler, Volckner, Riediger, & Ringle (2009) defined is a strategy wherein the name of a certain product is being used for people’s familiarit y to introduce a new product. This strategy can help the product to increase its demand in the market. Polo Shirt as the Product Considering Polo shirt as the parent of the brand extension, it has several possible outcomes such as body towel, underwear and socks. To come up with a successful brand extension, principles are to be considered. ... Of course, if the producer has already earned his consumer’s trust, it is better if they could provide what the consumer need so that they will not be dismayed. The parent should still have the power to control the extended brand for they still have the same name thus, has an effect with each other’s credibility through their consumer’s opinion. Also, confusion with the extended brand with the parent is a big no. Though they are of the same brand, the products are just co-related with each other and so, should not be a cause for the consumer’s frustration and regret when used the wrong product. If the parent is more of cloth category just like the polo shirt, producers should not create unrelated categories such as soap or food products. Brand extension researchers (n.d) also added that brands should not be extended on different categories for it will affect the product’s name along the competition. Also, the extended brand should add to the parentà ¢â‚¬â„¢s credibility through recognition with new, efficient and successful category for the firm on the future. There should be business attributed upon having brand extension. It is good to think of the possible outcome of the brand extension upon having the developing plan. To engage into a brand extension is a good idea to increase your inputs in the market. Actually, Gelder (as cited in Kapferer, 1997) stated practical reasons why having brand extension such as: the consumers will experience new products and at the same time, the company will be updated thus, will actively participate on having new innovations as part of its development; Through brand extension, the consumer who used to have a trusted brand will choose it rather trying another one thus, making the product reach

World Trade Organization. Origins And Characteristics Essay

World Trade Organization. Origins And Characteristics - Essay Example Simultaneously, 23 countries (11 of which were developing nations) decided to negotiate on tariff reductions and also to adapt some of the ITO rules, these agreements are called the GATT. The ITO remained subject to ratification to be accepted by national legislatures, but the USA denied due to Congress opposition, and thus GATT remained in effect just as the ‘provisional’ agreement. Seven trade rounds were completed under GATT, and trade agreements were initiated which benefited the developing countries without reciprocal offers. The GATT agreements were extended in the Uruguay Round in 1986, under which new areas were added to the services trade and intellectual property rights were included. Furthermore, a new dispute settlement system had to be redesigned and a new trade organization had to be established to replace the provisional GATT. In the year 1995, the ‘Marrakesh Agreement’ established the WTO, and the Uruguay Round agreements were implemented and by 1997 the additional agreements were also implemented which covered the financial services and the telecommunication services. Furthermore, the defining characteristics of the WTO are as follows (Ministry of Commerce and MPDF, 2005, 11-16): Transparency is the primary principle, since business people are most concerned with the environment they operate in. Thus, it is a requirement for the WTO member to publish all laws and regulations transparently which may affect domestic or international trade in any matter. Non-discrimination principle ensures that the goods of any country must not be differentiated against, and therefore no ‘most favored nation’ treatment shall not be provided, and neither the local goods should be discriminated. Progressive trade liberalization principle applies because WTO is not a free-trade organization, therefore a government can increasingly open its market to foreign competition to the extent it finds appropriate, independently of what i s prescribed by the WTO agreements. Special and Differential treatment principle ensures that developing nations receive easier terms and agreements, and thus they are allowed more time for implementation, and the stricter rules applied on the developed nations may be removed from the agreement of the poorer nations, in order to help them take benefit of being WTO members receiving special treatment. b) An imperfect World Trade Organization is better than no world trade organization.  Discuss with reference to ongoing protectionist policies and the impact of these in the relation of developed economies and lesser-developed economies (40 points). WTO is an organization that was formulated to help and benefit its members, its system of rules, principles and obligations are in place to protect its member nations, which also comprises of the economically less powerful nations, since WTO helps governments of such nations to devise programs which trigger economic reform. The multilatera l trade framework of the rules enacted also help nations in domestic policy making, they do not enforce trade policies but help governments in establishing developmental policies which are based on open and competitive markets. Regardless of the initial aim, WTO has been criticized for being unfair and hurting to

Organising Learning Essay Example for Free

Organising Learning Essay Furthermore, another area of concern for me is managing behaviour in the classroom. In my opinion, managing behaviour is a partnership between the teacher and the children. The teacher must be the authority figure in the classroom. I feel this is achieved once trust and respect is formed. Once routine is learned and the children know what is expected from them, a lot of pressure is taken off the teacher. In school, the children were constantly encouraged to put their hands up. If they called out the teacher would respond quickly and ask them to put their hand up. Therefore, I have found that unwanted behaviour should either be ignored or dealt with rapidly to reduce further problems. It is they teachers responsibility to decide how to handle a situation. The school has a behaviour policy which the whole school follows. I feel this is a valuable document and offers guidelines to handling challenging behaviour. The teacher uses smiley or sad faces on the board as a management strategy. In my whole school experience only saw three sad faces which was amazing. The Overall behaviour of the children was very good as the teacher used praise, smiley faces, well done points and stickers on a regular basis to encourage good behaviour. The children thought very highly of the teacher and tried hard to please her. I tried to use the teachers classroom management strategies as the children were familiar with them and the children responded to the in a positive wing the very lucky teaching the class as they showed a genuine interest in my lesson and behaved extremely well for me. I feel this was because I tried to make it interesting. I tried to pitch the lesson to their level so they could relate it to their experiences. Meeting the needs of individual children is a constant challenge. Some children may need individual help all the time and there are some children who have special educational needs. Therefore, there needs must be planned for and a lot of praise and encouragement is needed to reward their progress, so they dont feel excluded from the rest of the class. I believe this is extremely important; an effective teacher must be able to meet the individual needs of every child in the classroom. At university I particularly enjoy science and English lectures. The tutors are friendly and approachable which I feel is because they make sure we all understand the lesson. They quickly recognise if any students are struggling with their work and offer different methods of learning. I feel comfortable participating in these lessons as I feel quite confident in the subject. These tutors also give us the opportunity to discuss our thoughts and ideas with each other which I also think is an effective method of learning. I have also found that assessment is a vital part of teaching and this is an area of concern for me. It is especially vital to assess children at the end of each key stage to provide an individual report they can take with them, which highlight their strengths and possible growth points. Although a teacher will know what level their pupils are at, it is now important to have evidence to support their judgmentsDuring my school placement I observed the teacher assessing the children on a regular basis. Questioning the children is an effective method to establish what level the children are at, this is accomplished in an informal manner and the children are not pressured. The teacher built on the results of the assessment during teaching and addressed any misconceptions which the children may have. Another method of testing was seen at the end of each topic, the children answered questions on a worksheet which provided physical evidence to support the teachers judgment. Sometimes check-lists can be used for smaller groups during some activities which have been planned for assessment. I observed year one and year three and upper key stage two. I saw the same behaviour management in all the classes. Year six children were given more responsibility over their time management and behaviour as the expectations were shared with them from the beginning. Year six did not sit on the carpet, all teaching took place at their tables. It helped to see how the children progress and the NNS and NLS is a valuable document which tells teachers how to develop the childrens learning. I am concerned about becoming an effective teacher, and it is vital that all teachers should recognize their strengths and weaknesses. They should reflect on previous lessons and be able to set targets. I feel that teaching is an occupation where the teachers are also learning alongside the children. Sometimes lessons may not go as well as we anticipate or sometimes they may be better than previously thought. All this should be recorded by evaluating our progress after each day and building on our professional development. It is crucial to act upon areas which need improvement. In conclusion, I have highlighted my concerns of becoming an effective teacher. I have included possible ways to improve areas such as classroom management and behaviour. I have also included my school observations for examples of the teacher giving and receiving respect from the children. I have also included forms of assessment and self reflection which are crucial aspects of teaching. In my opinion, teaching is not simply a career, it becomes part of your life. A creative and stimulating teacher would gain great personal satisfaction from this profession and my school placement has confirmed my desires of becoming an effective classroom teacher. It is important for a teacher to be happy, organised and enthusiastic in school, knowing that they are making a difference to a childs future. Bibliography Collis, M. Lacey, P.

Lephalale Exxaro Training Centre

Lephalale Exxaro Training Centre The purpose of this report is to provide a description of the period of vacation work spent at Exxaro Resources Grootegeluk mine. The requirement was set to the student to spend time with and work with artisans in their everyday environment to gain valuable practical training and experience. The training provided a broad overview of the environment that an engineer can be exposed to and must be able to handle during his or her practice. A comprehensive understanding of different disciplines was attained by working with diesel mechanics, millwrights, electricians and fitters. Tasks completed range from the manufacturing and assembly of components to the maintenance of existing systems and troubleshooting of systems that dont function as expected. The incorporation of a study of personnel management added another dimension to the training period by informing the student about the enabling, employee lifecycle and supportive services offered to the employee to ensure a satisfying and adv ancing working environment. INTRODUCTION Exxaro Resources Ltd is a South African mining company that owns coal, mineral sands, base metals as well as industrial metal related assets. The majority of its revenue is however generated by its coal mining business units. Exxaros Coal Mining Division is established as the fourth largest producer of coal in South Africa with eight different coal mines throughout the Limpopo and Mpumalanga provinces under their control. Exxaros Grootegeluk Coal mine in Ellisras in the Limpopo province is an open-cast coal mine with the largest coal beneficiation facility in the world. It supplies power station coal to the Matimba Power Station and also produces coking coal for use in the production of steel, as well as high quality metallurgical coal. It is also the home of the Medupi power station expansion project which, after completion will lead to Grootegeluk being the largest open-cast mining facility in the world. CONTENT 2.1. PRACTICAL TRAINING 2.1.1. SECONDARY MINING MAINTENANCE 2.1.1.1. INTRODUCTION The central workshop on the Grootegeluk site is responsible for tasks such as repair, maintenance, assembly and fabrication. The workshop is divided into three sections, namely Mining Maintenance, Plating and Refurbishment. The secondary mining maintenance section situated in the central workshop on the Grootegeluk site is primarily responsible for the maintenance of the water trucks, tippers, low-beds and smaller trackless mobile machinery. Time was spent working in this section, in cooperation with diesel mechanics, to acquire knowledge of the maintenance and operation of the trucks. 2.1.1.2. TRUCK INVENTORY 3 water trucks and 3 tippers are required to operate at any time. The trucks used are supplied by Caterpillar and are classified as the CAT 777 models. The models that operate on the mine currently are the CAT 777D and CAT 777F models. The plan at the moment is to phase out the CAT 777D trucks and incorporate the newer CAT 777F models. 2.1.1.3. LAYOUT OF CHASSIS AND POWER TRAINs A major advantage of the fact that the CAT 777 models are being used is the fact that the chassis and power train can be used interchangeably between trucks that are of the same model. Depending on what is required, either a water tank or bucket can be mounted on the chassis making it a versatile alternative to the purchasing of trucks manufactured for specific purposes only. The trucks are powered by an 870 horsepower, 27.9 litre engine. The power from the engine is sent through a torque converter, which is followed by a prop shaft leading to a semi-automatic transmission, differential and the left and right rear final drives. The basic layout of the truck can be shown as follows: 2 2.1.1.4. WATER TRUCKS Responsibility of water trucks: Spray water on the mine roads to reduce the amount of dust caused by the passing of trucks and mine machinery In the event of a fire on the mine, the water trucks may be used to extinguish the fire by use of a nozzle mounted on the front Capacity: The total load carrying capacity of the water trucks depends on the model. The capacity of the tank on the older CAT 777D trucks is 80000 litres while the tank on the newer CAT 777F has a slightly larger capacity of 82000 litres. Pump and spray system: A centrifugal pump system is used at the back of the truck to pump water from the tank to the spray nozzles. Water flows down from the tank into the pump where it is then rerouted upwards into the piping system leading to the spray nozzles. The spray nozzles then project a jet of water at a small obstruction which again changes the direction of travel causing the water to disperse Diagram of piping: Diagram of side view of spray nozzles 2.1.1.5. TIPPERS Responsibility of tippers: Waste and overburden in the mine is defined as rock and soil that cannot be used for the extraction of product. It also includes the waste produced during the extraction of the product. Because of the small amount of coal content that might still be present in the waste there is always a risk of spontaneous combustion. The tippers are responsible for moving and dumping red sand and topsoil on the waste dumps and the areas around the pit to shield the area from intense direct sunlight and reduce the probability of spontaneous combustion. The tippers also operate occasionally in the pit together with front-end loaders to clean out small amounts of material that the shovels and larger trucks are unable to collect because of the lack of space for operation. Capacity: The load carrying capacity of the tippers is dependent upon the condition of the hydraulic system used to lift the bucket. Two hydraulic cylinders are used to lift the bucket and tip the load. In a brand new condition, the tippers are able to handle a load of 120 tons while a tipper that has been in service is typically only loaded up to 100 tons to ensure that the system will be able to dump the load. 2.1.1.6. SERVICING THE TRUCKS In the coal mining environment, the trucks are required to be serviced after every 300 hours of operation. During the training period, both the CAT 777F and CAT 777D models were serviced. The 300 hour service on the CAT 777D truck entails the following: Sampling 3 different samples of fluids were taken while the engine was still running Engine oil Transmission fluid Hydraulic fluid 6 more samples were taken after the engine was switched off Left front hub oil Right front hub oil Left final drive oil Right final drive oil Steering fluid Differential oil These samples were then sent to the mine laboratory. The samples are then analysed to check for the presence of iron filings or debris that could indicate the presence of wear on the components. Replacement of filters The sump plugs and used oil filters were removed to drain the engine oil Although the primary sump is the most important to be drained, the engine also has a small secondary sump that was also drained Used oil was caught in an oil trolley New oil filters were installed Diesel filters were removed New diesel filters were installed New steering filter was installed Checking the fluid levels The level of the oil in the final drives, front hubs, differential, hydraulic system and transmission were checked Transmission fluid was filled up Engine oil was filled up The servicing of the CAT 777F trucks was handled by certified Barloworld technicians, since the trucks have only been operating on the mine for a short time. Mechanics present in the workshop had to thoroughly observe the tasks that the technicians were performing in order to learn what needs to be done. Eventually the task of servicing will be handed over to the diesel mechanics. 2.1.1.7. DRIVING THE TRUCKS The trucks operate using as semi-automatic transmission. This transmission eliminates the need for a clutch pedal, leaving only a brake pedal and an accelerator pedal. A torque converter is however incorporated with the gearbox to fulfil the purpose of the clutch. Three different braking systems are available on the trucks. Operators seldom use the foot brake which exerts a braking force on the all four wheels of the truck because of the heat generated. The steering column is fitted with levers to operate two other braking systems. The retarder lever is primarily used to slow the truck down by exerting a braking force on the rear wheels. The secondary lever is a last resort for operators and, when pulled, exerts a braking force on all four of the trucks wheels simultaneously. When the trucks are stationary and the engine switched off, the park brake has to be engaged. Additional stop blocks are placed behind the wheels of the trucks to prevent them from rolling. When the truck needs to be driven the following steps are taken: Engage the park brake Engage the retarder lever Select the number of gears required from the transmission Disengage the park brake Disengage the retarder lever Press the accelerator pedal The transmission will shift through the number of gears selected Steer the truck 2.1.2. CENTRAL WORKSHOP: PLATING 2.1.2.1. INTRODUCTION The central plating workshop at Grootegeluk mine is responsible for the majority of the sheet metal work that needs to be done on the mine. Artisans in this section have the task of manufacturing and assembling components of structures or machinery in and around the mine. The plating workshop also has facilities to sandblast and spray the components manufactured. The majority of the workload of the workshop finds application in the production and beneficiation plants. Time was spent with boilermakers in order to gain an understanding of sheet metal work. 2.1.2.2. MATERIAL Mild steel and stainless steel are the dominating types of steel used in the workshop. The type of material used for an application is in some instances limited by the capabilities of the available machinery. 2.1.2.3. PREHEATING Preheating of materials is an advantageous process when welding has to be performed and aids in the assurance of a strong, quality weld. Four main reasons for preheating exist. Preheating of the metal reduces the rate at which the welded component cools down. Rapid cooling of the welded joint could cause shrinkage of the metal in the vicinity of the weld which eventually leads to the formation of cracks and reduces the strength of the weld. In materials with low ductility, the shrinkage stress in the weld area could cause extensive deformation of the component after welding. Preheating lessens the effect of distortion by giving the welder the opportunity to utilise a momentary increase in ductility during the welding process. When the temperature of the parent material that is being used is too low, it can cause the deposited electrode metal to cool rapidly, leading to the prevention of the fusion of the metals. Preheating lowers the risk of this situation occurring. The amount of preheating required is dependent upon the thickness and configuration of the plates to be welded. The final reason for preheating relates to the presence of moisture on the surface of the metal. If the surface of the metal is wet during the welding process it could lead to the rejection of the weld or an accelerated tempo of surface crack formation in the welding region. 2.1.2.4. TIPS FOR FLUX-CORED ARC WELDING The flux-cored arc welding used in the workshop uses a wire electrode which is shielded by an appropriate gas. In general, flux-cored wires are manufactured to function with either carbon dioxide or a mixture of argon and carbon dioxide as shielding gas. The shielding gas prevents the spark from causing the uncontrolled dispersion or oxidation of the electrode metal. Flux-cored arc welding is generally performed by dragging the welding gun along the joint that needs to be welded. When welding t-joints it is important to maintain the welding gun at a 45à ¡Ã‚ ´Ã‚ ¼ angle to ensure that the electrode metal is evenly deposited in both pieces of metal. When completing butt welds the torch needs to remain in an upright position and should not deviate from the upright position by more than 15à ¡Ã‚ ´Ã‚ ¼. This will also ensure even distribution of the electrode metal during the welding process. 75à ¡Ã‚ ´Ã‚ ¼ 2.1.2.5. EQUIPMENT Welding Lincoln electric Idealarc DC-600 power source Direct current welding power source with a maximum current output of 850 A and maximum voltage output of 44 V Lincoln electric LN-25 PRO semi-automatic wire feeder Wire feeders are connected to the power source to feed electrode wire through the welding gun Tri-mark TM-791 Flux-cored electrode wire used in conjunction with CO2 as shielding gas Matweld Anti-spatter Silicone mat 0810 Spray canister that is used to prevent the spatter of electrode metal during the welding process The spray is applied to the welding gun Cutting torches: Two combinations of gases are used in the cutting torches. LP gas and oxygen are used together, or acetylene and oxygen Lighting the torch The operator opens the LPG or acetylene feed and lights the gas After the LPG or acetylene has been lit, the oxygen supply is opened to enhance the flame An optimal flame to cut metal with is a quiet flame of blue colour with no visible or distortions Application of torches Torches are primarily used to cut mild steel in the workshop. Torches cannot be used to cut stainless steel. Technically speaking torches do not cut, they burn the metal. Burning involves oxidation of the metal. The high temperature of the flame accelerates this oxidation process. Stainless steel has low iron content and will not rust in the presence of the flame. Automated cutting torch This machine has the ability to follow a shape by means of a proximity eye on a table at the left side of the machine, while simultaneously moving the torch in the exact same pattern to cut a component from metal plates on the right side of the machine. Shapes are drawn and cut out on a yellow plastic sheet. The edges of the shape are then painted white. The shape is then placed under the eye which follows the outline of the shape while cutting the metal in the same way. Plasma cutter: Cebora Plasma Prof 80 art 947 Uses only compressed air to make accurate cuts in metal up to a thickness of 20 mm and rough severance cuts up to 30 mm Operation: The plasma cutter used in the workshop utilises high pressure gas which is sent through a small tubular gun. The small tubular gun contains a negative electrode that creates a circuit when the gun is brought close to the metal. This electric spark caused by the circuit causes the gas to be heated into the plasma state of matter and reaches a temperature of about 16000à ¡Ã‚ ´Ã‚ ¼C. This extremely hot plasma then melts the metal that is being cut. The plasma cutter can be used to cut any metal. In the workshop it is used to cut stainless steel plates. Sandblasting equipment: Spartan engineering 800M pressure vessel 200 L capacity The purpose of the sandblasting equipment is to clean and remove paint from the surface of metal components which then prepares the surface to be spray painted. 2.1.2.6. TASKS OBSERVED Due to the nature of the precision and accuracy required to complete the jobs, most of the time in the workshop was spent observing and assisting. The following jobs were in progress: Manufacturing and assembly of waste buckets Waste buckets are used around the mine for different waste material. These waste buckets are made by the mine boilermakers. Three waste buckets were being built for use around the mine. Plates for the structure had to be cut, bent and welded together using a cutting torch, bending machine and welding machine. Basic side layout Basic front layout Wear plates Two sets of wear plates are used as sections of a vibrating beam in one of the assemblies in the plants One set of plates have six holes through which it fastens the beam The second set of plates are rectangular and support two springs Because of the magnitude of the forces acting on these wear plates, bearing failure of the plates occurs during operation. This wear is however allowed and monitored for a period of time before the beams are then removed and the worn out plates cut off New wear plates were manufactured according to specification Clamps for pipes Clamps were manufactured to fasten the pipes used in the plants Haulpak truck operators cab Boilermakers assembled the frame of an operators cab for one of the Haulpak trucks. Drawings were supplied giving detail of the cover plates that had to be fabricated, as well as assembly drawings to show the final required layout. The welds utilised were to be either 3 or 6 mm one-sided fillet welds. The M12 nuts that were used to assemble the frame also had to be tag welded. Extractor fan piping system Maintenance on the plants requires occasional replacement of the piping on the extractor fan system. A 6 pipe assembly was manufactured to replace the old system. Flanges were cut and holes for bolts were punched. Pipes were cut to the appropriate lengths and shapes after which flanges were welded onto the pipes. 2.1.3. GG 3/4/5 AND WASTE MANAGEMENT WORKSHOP 2.1.3.1. INTRODUCTION The GG 3/4/5 and waste management workshop at Grootegeluk mine is responsible for the mechanical and electrical maintenance of the GG 3,4 and 5 plants as well as the system set up to convey waste to the dumps. A wide variety of systems, from substations to conveyor belts, are the responsibility of the artisans in this workshop. Time was spent with fitters and electricians to gain an understanding of the tasks required. 2.1.3.2. TASKS COMPLETED Replacement of motors in GG 5 tunnel: After completing the necessary safety protocol the first task was to replace two 380 V electric motors in the GG 5 feeder tunnel. The job required both electricians and fitters to complete and was completed by these steps: Since the motors operate on a 380 V control voltage, the first task was to cut the electricity supply to the motors by isolating the breaker in the substation The new motors, weighing in at 118 kg each were carried down into the tunnel using a sling wound around the motors The electrical supply wires in the cable box were disconnected After disconnection, the bolts on the old motors were loosened and the old motors were removed The new motors were then hoisted into place by a small handheld portable crane The bolts were fastened to keep the motors in place The electrical supply wires in the cable box were reconnected The supply to the motors in the substation was switched on The final step was to check if the motors were in fact turning in the right direction Proximity sensors: The job relating to the proximity sensors required the attention of electricians and required thorough investigation into and troubleshooting of the wiring circuit leading to the sensor on the feeder motors. The proximity sensors kept burning when they switch after connection. The function of a proximity sensor is to detect the presence of a metal component within 5 mm of its periphery and takes the form of a small circular cylinder with a threaded outer casing and electronic components inside. These sensors are used to indicate to the operator whether the lever at the electric motors has been engaged. This prevents the motor from running without being engaged to the feeders. The troubleshooting followed a sequential path: First the cable leading from the junction box at the motors was followed back to the PLC in the substation The basic function of a PLC (Programmable Logic Controller) is to provide an electronic interface between the supply and the components The PLC can be set up to perform certain tasks during certain time intervals and can also receive and respond to inputs from other electronic components From the PLC the total length of the cable was divided into 4 sections PLC to distribution panel Distribution panel to junction box Junction box to cable box Cable box to proximity sensor The connection at the proximity sensor requires the presence of a live and neutral wire At first glance the suspicion was that both the wires available were live wires, thereby causing a short circuit when the proximity sensor switches A Meggar insulation tester was then used to test each length of cable The basic function of a Meggar is to test the magnitude of insulation between the conductor and the earth A low reading on the Meggar indicates the possible presence of a short circuit or damage to the wire insulation After the use of the Meggar the proximity sensor was sequentially wired into the circuit at each section and tested Eventually the short circuit was found between the cable box and the proximity sensor Servicing of slip ring motors; The high voltage electric motors used to drive the waste conveyor belt system are 6.6 kV slip ring motors. These motors need to be serviced regularly to ensure efficient functioning of the system and to prevent the motors from being damaged. Equipment needed: Meggar insulation tester Blower Cleaning solvent Extension cord In order to complete the service of the slip ring motor, the following steps had to be taken: The electrical supply to the motor was cut off by isolating the breaker in the substation The side cover panels of the electric motor were removed Twelve brushes inside the motor were then removed from the brush holders Special care had to be taken to make sure that the brushes dont touch each other The Meggar insulation tester was then connected to the slip rings Negative terminal connects to the body of the motor Positive terminal connects to the slip rings An initial reading of 640 MÃŽ © was recorded The control voltage on the motor is an indication of the reading required from the Meggar For a 6.6 kV motor the reading from the Meggar should at least be 6.6 kÃŽ © The Meggar was removed and the inside of the slip ring and brush casing was blown out with the blower After blowing out dust and fine copper, the slip rings and the inside of the casing were wiped with a cloth and solvent to remove the last bit of fine copper The Meggar was reconnected and a reading of 3.22 GÃŽ © was obtained which was adequate The side cover panels were replaced and the electrical supply to the motor was switched back on Replacement of a 6.6 kV slip ring motor: The 6.6 kV electric motors used for the conveyor system eventually deteriorate in such a manner that they cannot be brought back to an acceptable operating state by means of a service only. These motors then need to be replaced and are sent away to be properly refurbished if it is possible. The following steps were followed: The electric supply to the motor was cut off by isolating the breaker in the substation The electromagnetic drum brake was released and moved out of the way The shaft coupling (jaw coupling) between the shaft on the motor and the shaft on the gearbox was disengaged The panels covering the electrical phase terminals and winding terminals were removed and the supply cables were disconnected The next step was to loosen the bolts at the bottom that fasten the motor to the structural frame The old motor was then hoisted by means of a forklift and removed The new motor was then put in place The electric supply was reconnected to the phase and winding terminals The bolts at the bottom of the motor were fastened slightly and the shaft coupling replaced to prevent excessive movement of the motor Alignment of the shafts was then done Shaft coupling was properly engaged The bolts on the structural frame were fastened 2.1.4. CONVEYOR BELTS 2.1.4.1. INTRODUCTION A brief introduction was given to a typical engineering problem to provide insight into what is often required from engineers. The belt on the waste management system leading to the dump needs to be extended. This is causing problems in terms of the power required from the slip ring motors. The extension of the belt causes additional load to be hauled by the motors. The motors that are currently installed trip when started up on full load. Time was spent studying and applying calculation to determine the power required from the motors to drive the conveyor belt system. 2.1.4.2. POWER REQUIREMENTS OF CONVEYOR BELT SYSTEMS The governing factors relating to the power requirements of a conveyor belt system concerns the provision of the necessary force to overcome the resistances posed by the entire system. These resistances can be divided into 5 subsections: Main resistances FH Secondary resistances FN Special main resistances Fs1 Special secondary resistances Fs2 Slope resistance Fst Main resistances: The main resistances that the motors have to overcome relate to the resistance of the rotating idlers, the resistance by the movement of the empty belt, the resistance of the material to horizontal movement as well as the resistance of the belt due to a slope along its conveying length. The resistance posed by the rotation of the idlers is manifested in the form of the frictional resistance of the idler bearings and seals. Rotational inertia of the idlers also contributes to the resistance posed. The belt creates resistance by means of the indentation resistance of the belt on the rollers. The flexure of the belt and the material that the belt is made of also resists the movement of the belt. An overall calculation to determine the resistance due to rotation of idlers and movement of the empty belt takes the following form: FH1 = (qro + qru + 2qb cos ÃŽ ±) x f x L x g qro Mass per unit length of rotating idler parts on the carrying side [kg/m] qru Mass per unit length of rotating idler parts on the return side [kg/m] qb Mass per unit length of the belt [kg/m] ÃŽ ± Angle of inclination [degrees/radians] L Centre to centre conveyor length [m] g Gravitational acceleration [m/s2] f Friction factor due to idlers The mass of rotating idler parts and the mass per unit length of the belt itself is determined by means of the tables of specifications given in the design catalogue or procedure followed. This requires the belt width which can be decided upon or determined mathematically. These masses are then converted into mass per unit length by means of the following formulas: qro = mro/ao [kg/m] qru = mru/au [kg/m] ao carry side idler spacing au return side idler spacing The decision then needs to be made with regard to the selection of a friction factor. This is also specified by the design catalogue. The Phoenix Conveyor Belt Design Fundamentals catalogue provides the following guidelines for selection: f = 0.017 for well aligned belts with smooth running idlers and low friction f = 0.02 for normal applications f = 0.023 to 0.027 for harsh operating environments, high frictional forces and the occasional overloading of the belt The centre to centre distance can be described as the distance from the head to the tail of the conveying system and encompasses the total possible length over which material can be conveyed. This is usually a parameter that is pre-determined by the specific situation. Finally the calculation of the resistance due to the rotation of the idlers and the empty belt force can be done. The next calculation that needs to be done relates to the resistance of the material to being conveyed horizontally. FH2 = qm x L x g x f x cos ÃŽ ± [N] qm mass of the material per unit length that is being conveyed To calculate the value of qm needed in the above formula, the total capacity or throughput of the belt needs to known. qm = Qm/v [kg/m] Qm The capacity or thoughput of the conveyor system [kg/s] v velocity of the belt [m/s] The calculation for the resistance of the material to horizontal movement can now be done. The resistance posed by gravity due to a slope/gradient along the conveying length also needs to be taken into consideration. Fst = qm x H x g [N] H change in the elevation of the belt along the length [m] After this calculation, all the major primary resistances needed have been calculated Special main resistances: The friction caused by the movement of the belt past the chute flaps is regarded as an important factor that needs to be calculated as part of the power requirements. Secondary resistances: Secondary resistance to the movement of the belt takes into consideration the detail relating to the operation and design of the belt. When material is deposited onto the conveyor belt system, a force is required to accelerate the material in the direction of conveying. This force is manifested in the form of the change of momentum of the material when dropped onto the belt and. Additional resistance to movement is then imposed on the drive system. The presence of skirt plates in the vicinity of the chute to keep material from dropping off the belt causes more resistance to the movement of the belt. This resistance depends on the magnitude of the friction force between the belt and the plate as well as the length of belt in contact with the plate. Occasionally the skirt plates also cause the material to exert a force on the belt which leads to additional frictional resistance. Other secondary resistances also include the resistance caused by the pulley bearings and the wrap of the belt around the pulleys. Special secondary resistances: Additional systems installed on the belt can also cause resistance to the movement of the belt. The basic operation of belt cleaners leads to friction forces being present between the belt and the material as well as between the material and cleaners. These friction forces, combined with the forces of the discharge ploughs, impose an additional load that need to be overcome. The inversion of the belt at the head and tail causes resistance to movement due to the combined effect of the flexure of the belt material and the friction of the pulleys. When designing a long conveyor belt system, the magnitude of the primary resistances generally exceeds the magnitude of the secondary resistances. To simplify the resistance calculations, the secondary resistances are simply accounted for by means of a correction factor on the primary resistances. C = 0.85 + 13.31L-0.576 for 10 < L < 1500 C = 1.025 for 1500 < L < 5000 L Conveying length [m] When this factor has bee

George Street Bridge Project Charter

George Street Bridge Project Charter This Project Charter outlines the budget, schedule, scope, milestones and delivery strategy for design construction of the George Street Bridge, Newport. This charter also includes the major risks and risk mitigation strategies associated with this construction Project. Once the project charter is complete, the project team will finalize a detailed construction schedule. And after the approval is granted by the Council, the project will be guided by this Charter. Background and problem statement This project focuses on the construction of a reliable and safe street bridge in Newport. It has been observed that during peak hours in the city, the high speed traffic makes it very unsafe for pedestrians and cyclists to cross the street. Thus the construction of a crossover bridge with bike lanes and trails has been suggested that can improve the road safety for pedestrians and cyclists. Scope The scope of this Project includes: Construction of a new bridge of modern standards; 2 travel lanes; Bike lanes in both directions on the bridge; Trails for both pedestrians and cyclists Separate pedestrian pathway on the north side of the bridge; Traffic Signal intersection at Harbor Road; Links to existing and future pathways and trails; Improved approach roads to the bridge; Improved safety and accessibility; Relocations of utilities; Decommissioning of existing construction on the area where the bridge is to be constructed; Landscaping; and Public art. This project aims at providing alternative transportation amenities. This bridge will ensure that the pedestrians and cyclists can safely pass through the high speed traffic. This bridge will improve the city infrastructure and will lead to orderly traffic movement. Objectives This bridge will be a sustainable bridge with improved cyclist and pedestrian amenities. The objective of this project is to build a bridge that will provide a transportation link on the George Street. The bridge will be constructed following all the construction guidelines of Newport city. The bridge will link existing and future trails and pathways. This bridge follows all the laid down policies of development and transportation, and will support the economic vitality of the downtown. This project will create jobs during the construction period and the traffic to and from the city will be minimally impacted. Project Team The Project Team will consist of the George Street Bridge Project Director, the Project Team, which will be supported by professional expertise and key staff in areas of finance, engineering and procurement. Also experts form audit, legal, communications, risk management, and from other areas as required will be assisting the project management team. The project team will also include professional engineering support from the chief consultant. The team will have support from sub-consultants which include bridge architecture, structural, quantity survey, geotechnical, mechanical electrical during various phases of the project. The chief consultant Group has expertise and experience in constructing bridges. In addition to the above, the chief consulting team can provide recommendations related to design-assist procurement as well as contractor procurement. Issues 1. Numerous stakeholders with diverse interests are involved. 2. Project delay would impact many citizens of Newport city 3. Since the global economy is recovering, a large number of pending projects might start in same timeframe as George Street project. Risks and risk mitigation Construction projects are characterized by the presence of many risks. Some of these can be directly controlled by the project management team, while there are others that are linked to the market. Some of these risks are major ones that can have a significant impact on the project budget or project schedule. The major risks and the risk mitigation technique to control risk are as follows: Steel Prices: Steel represents a significant portion (approximately 45%) of the bridge material and cost. Steel prices are affected by global economic drivers. This can be mitigated by securing steel unit prices by signing contracts with the suppliers well in advance or placing them on the design assist team. Market conditions for construction: Market conditions for construction may change. This is again linked to the market and cannot be controlled by the project management team. This risk can be mitigated by securing a general contractor as early as possible to work with the design-assist team Competing projects: Competing projects draw resources and contractor interest away from the ongoing project. This can again be checked by securing a contractor on the design team. Actual site conditions vary On many occasions the actual site conditions vary significantly from what has been expected. To control this risk additional geotechnical investigation work can be carried out. Utility relocation Significant delay in utility relocations takes place. Project managers can work towards having more cooperation and coordination with external utilities providers. Other risks could be lengthy gap between construction disciplines or conflicting instructions from clients staff to contractor. These risks can be mitigated by having better communication and coordination or with the use of appropriate cost control measures and project management techniques. Change Management Any Significant changes in the scope of the project will be approved by the Management Committee. These changes could be changes in the items list provided under Scope. But these changes will be well within the contingencies provided in the project budget. If any of the changes appear to fundamentally alter the mandate then they will be presented to Council and the management committee for final approval. These could be changes in the deliverables listed under Scope. The authority to make critical decisions will be with the George Street Bridge Project Director. Quality Assurance The responsibility of overall design of the bridge will vest with the prime consultant for the project. The consultant will be responsible for the design integrity of various works undertaken under the George Street Bridge contract. The chief contractor, after appointment, will be responsible for complying with the design as shown in the design documents prepared by the consultant Group. The quality assurance program will aim at delivering regular reports to the city project team during fabrication and construction stages in a pre decided format. Budget: The estimate cost of designing and constructing the George Street Bridge is estimated at $20 Million. This estimate assumes that there will be no significant change in the current economic conditions and the steel prices will not increase significantly. The budget also assumes that quality labour will be available throughout the construction of the bridge. This budget includes a contingency of 10% as recommended by the chief design consultant which was reviewed by an associate consultant. The construction of this bridge involves a significant quantity of steel, representing approximately 45% of the current estimate as mentioned earlier. Cost control measures will be employed throughout the project lifecycle to monitor and track the budget. Funding for the Project is as follows: $10 million City borrowing $3 million Reprioritization of City capital projects and other internal sources $7 million federal Contribution Agreement TOTAL $20 Million Timeline: The timeline for this construction project considers the time required for steel manufacturing and fabrication; erection and testing; and construction of the piers, detailed design; bridge assembly abutments and approaches. The project manager aims to complete the project by no later than March 31, 2015. Project constraints The following are the project constraints that can impact the completion of this Project: 1. Regulatory requirements 2. Disbursement of utilities 3. Construction economy 4. Availability of resources and construction materials 5. Unstable global steel market Most of these are not in direct control of the Project Team. Assumptions The Project completion assumes the following: 1. The Economic situation remains almost stable 2. Steel prices will not increase dramatically 3. There will be very few changes in the ground conditions 4. Coordination with fisheries windows to minimize delay construction 5. Steel materials and fabrication resources are available 6. Utilities will be available on time and will be well within budget 7. Qualified Engineers and Contractors are easily available 8. All the decisions are well informed and are as per the schedule Management Accountability Approach The sustainability of a project depends on the sustainability of its stakeholder relationships. There are many stakeholders having different proportions of stake in a project. Stakeholder management is essential for a successful project. An active reporting system will be followed to keep the stakeholders involved and updated. Progress Reporting A quarterly summary report will be provided to the Council and the stakeholders. Informal reporting will also be done through weekly meetings of the project team members and/or their representatives. Active use of internet will be done to keep both the public and the staff informed of developments of the project. Arrangements will be made to update regular reports on the project website. The project will be a success if the project manager is able to complete the project on time with enhanced safety and reliability. The bridge will be a model for other construction projects taken up in the city of Newport. The project will be successful if it achieves its objective of improving the crossing experience for pedestrians and cyclists.

Communication Accomodation Theory Essay -- Communication

The Communication Accommodation Theory states when people interact they alter their speech to fit in or accommodate for other. CAT describes the psychological, social, and linguistic behaviors that people exhibit when communicating with each other (Coupland, Coupland, Giles, Henwood, 1988). Each individual has his or her own personality and motivation when involved in a conversation, this attribute are reflected in how the individual speaks, listens and then responds to the other person involved in the conversation. According to this theory, communication between two people can at any time be adjusted by either party in response to actual, perceived, or stereotyped expectations of the other person (Coupland, et al., 1988). This means that either party can change their communication style based on what they feel or pick up on during the conversation. The CAT theory can help understand how humans interact with one another while communicating. CAT is based on the premise that speakers and listeners unconsciously and mutually modify their linguistic (e.g., language choice, vocabulary) and/or paralinguistic (e.g., dialect, tone of voice, speech rate) behaviors to become more similar to (convergence) or different from (divergence) their interactional partners (Giles, Mulac, Bradac, & Johnson, 1987). Convergence strategies signal interactants' positive attitudes toward each other, such as increasing attractiveness and approval or showing solidarity, whereas divergence strategies accentuate differences between interactants (Giles et al., 1987). CAT is based on the idea that people with unknowingly modify their language to become more similar or from the person they are communicating with.

Earnest Hemingway Essay -- essays research papers fc

Earnest Hemingway As one of the 20th century's most important and influential writers. His writings drew heavily on his own experiences for his writing. His writing reflected his trouble with relating to women and his tendency to treat them as objects, as he had four marriages and countless affairs, highlighting his theme of alienation and disconnection. Now here is why he is what he is by writing about what he was. Ernest Miller Hemingway was born on July 21, 1899, in Oak Park, Illinois, to Dr. Clarence Hemingway and Grace Hall Hemingway. Oak Park was a mainly Protestant, upper middle-class suburb of Chicago that Hemingway would later refer to as a â€Å"town of wide lawns and narrow minds" (Gerogiannis 188). The second among six children, Ernest spent the first two years of his life dressed as a girl by his mother. She called him â€Å"Ernestine† and fantasized that he was the twin of his older sister, as she dressed them both in matching dresses and gave them similar hairstyles (Rozkis 233) As he grew older, however, his father stepped in and insisted that Ernest be â€Å"raised like a man,† teaching Ernest how to behave and introducing him at a young age to hunting, fishing, and boxing, all activities in which he would stay interested for the rest of his life (Gerogiannis) It is perhaps this early start at questioning his manliness and his father’s attempts to drive any femininity out of him that instilled his characteristic obsession with proving his masculinity throughout his life. Schlusemeyer 2 Hemingway received his schooling in the Oak Park public school system. In high school he was mediocre at sports, joining the football, swimming, basketball, and water polo teams and serving as the track team manager (Nelson 5). He began his journalistic career writing for the school paper, the Trapeze, where he wrote his first articles and often humorous pieces in the style of Ring Lardner, a popular satirist of the time. After graduating in the spring of 1917, against the wishes of his parents, he forwent college and took a job as a cub reporter for the Kansas City Star. It is here that the seeds of his unmistakable staccato writing style were planted as he followed the rules of the Star’s stylebook exactly. â€Å"Use short sentences,† it said. â€Å"Use shor... ...Modified August, 1999.
