Social construction gender

The Social Construction of Gender Associated with Disordered Eating Patterns. In the US alone, there is reported to be over 1 million malnourished cases. Of all the above, a significant percentage are self-imposed malnourishment, which implies that, they do not occur as a result of lack of nutritious food but rather as a result of the rush for beauty. More than ever before, women want to look and feel thin and ‘small’. This is what is in the contemporary times viewed as beauty. The media, community as well as peers have all contributed to the development. This paper explores the concept of thinness as reflected in the contemporary society especially the role of eating disorders in the endeavour for beauty. 1. Introduction The social construction of gender has been attributed to numerous challenges facing women since time immemorial. Numerous happenings which influence or affect human beings have been given a social interpretation and therefore resulting onto the coining of the term â€Å"social construction†. The term basically refer to those belief widely held by the society which influence the interactions. In reference to gender, social construction refers to the social process in which men and women are subjected to different conditions in an endeavour to understand better how each one functions as well as the interconnection between the two genders. Social construction aims at looking at the effects the differential treatment of women has on their social life as well as their cultural practices. Although not widely researched on, social construction of gender had much influence on eating patterns. The fact that modernization has yielded much pressure on today’s human is a point to the fact that social construction is in action in almost all spheres of life. Unlike in the fact when beauty has not so much tied to one’s body weight/mass. The 21st century has seen a rise in the emphasis given to being slim especially on the part of women although overweight, obesity or under weight are problems that affect both gender, not is worthy noting that much of the emphasis on keeping fit in the sense of remaining slim is usually used in regard to women. From a gender perspective women are under much pressure to look and keep’ smart. The reason why majority want to remain slim is due to social pressure which stems from the fact that many cultures and especially the western culture value slimness and views it as a lading quality of beauty. The following discussion focuses on self-scheme less space as well as lack of voice as basic concept which advances social construction of gender. On the other hand, the discussion analyses gender identity from a woman perspective while at the same discussing the valuable concepts such as the power associated with beauty as well as the pressure of period the community at large as well as the effects these have on women. . Self-Schema This refers to the experiences of people in regard to their interactions with the society. Self-schema has been defined by, Lorber, & Farrell,(1991) as the organization of personal information all related to one experiences all of which have an impact on what people do and focus on. In regard to social construction, self-schema may refer to how wome n perceive and describe themselves. Such may include women role in the family women and leadership, women and beauty, which is the main focus of this paper. Schema in human beings is concerned with beliefs, pas experiences in life. In case of women various schemas can be attributed to eating disorder. These includes, what the society holder as the ideal weight, what the society beliefs to be the ideal height the ideal hair colour, the idea colour as well as what the society holds to represent heavily. The above contribute to childhood experiences as well experiences in teenage, early adulthood as well as late adulthood as well as late adult shapes ones mind set on many issues. For instances whether a lady perceives herself as beautiful cut, attractive or one of the above is greatly influenced by what she has undergone in life. The experiences shape beliefs over perception of the general public. In regard to women and dietary habits any consistent staring aimed at an overweight or round figured lady can lead to the lady believing that the stares are as a result of her body size, shape or figure and this further contributes to social construction of women. Self schema depends and is shaped by a woman’s experiences and at the same by stimuli in the society such as reactions from people, fashion, attitudes as well as cultural and environmental factors. Self schema on the other had is determined by the company or peers of a woman, the environment whether office or human environment. Determinants of self schema in women. Experience, how often a woman has been subjected to particular self-schema in women. Experiences of how often a woman has been subjected to particular self-schema determine how one is likely to respond or react. Importance of self-schema in women. While self schema could sometimes be detrimental to a woman’s health, the fact that some self-schema is represented positively is worth noting. Of particular interest to feminists is the fact that women who result of self-schema hold high opinions of themselves are more likely to resist social pressures which cause many women to confirm to society’s expectations which are mostly anti feminine. Problems of self-schema Self-schema can cause a number of problems to women. Such may include the development of stereotypes which revolve around certain attributes being assigned to specific groups of people. For instance, there exists, a stereotype about the western woman being slim and tall as apposed to African who are viewed as plum and short. Stereotypes can lead to misconceptions of facts and a lack of clear interpretation to meaning this in turn results into women suffering especially if the stereotypes come in the way of woman development issues. A. Disappear/Less Space A prejudice concerning a woman as not being beautiful for instance may put the particular woman at a disadvantage when it comes to making choices especially in her social life. For instance where prejudice of a woman in terms of her appearance and shape is dominant, chances are that the woman is more likely to suffer and be at a disadvantage compared to others who are not subjected to the prejudice. . Woman’s gender Identity Self schema may be problematic in that, they may lead to a woman being discriminated against in light of her beauty or lack of it. Since society mostly conceptual ones beauty a physical appearance, a woman may be discriminated against as account of her physical looks. This in turn may cause numerous effects in that the woman who is not equally physically endowed may miss out on opportunities she rightfully qualifies for. Woman gender identity From a gender perspective a woman has been portrayed as the weaker sex. Although it is hard to trace the origin of this common belief, it can be attributed to the domination of man in most spheres of public life such as politics and religion. Also the religious teachings of many religious have perpetrated this understanding in that their teaching which often call for nor-compromising adherence preach about how a woman should be submissive to a man. This has had the greatest impact in the lives of more women than any other factor, for instance, a woman is more likely to be denied a place in some churches or religious purely because of the fact that the particular religion teachers that. Power of beauty Power of beauty has been known to bring down ever the mightiest in the society. From the biblical records of King Solomon to Samson, from presidents to kings, beauty has been cited as one of the greatest assets the female gender has at its disposal. Even at household levels, beautiful women have a high bargaining then not so beautiful woman, for a beautiful woman, the beauty acts like a fall-back position and one is likely to use it to her advantage. However beauty as a gender concept is given different interpretation from culture to culture as well as from society to society, however, the immense power those of the females who are beautiful yield makes them at bargaining. The concept of beauty and the emphasis accorded to it has meant it more of a tool of bargain than it is a natural gift endowed to a woman. Women are investing in healthy and nutritious foods as well as seeking services of beauty consultants. Overall, the role of diet and food in beauty can not be over-emphasized. To remain beautiful, at least according to American standards one has to keep close watch on their weight, this has in turn has contributed to eating disorders. This is a big blow to proponents of health. Unlike in the past, currently the once promising trends as far as malnourishment cases in the society are concerned have started to revert and more cases of malnourishment are being reported. It is common knowledge that nowadays; women are keen to ‘keep fit’ at all costs. However, what makes the topic of interest and concern to social constructionist is the fact that the problem does not reflect in men as much as it is reflected in women. This phenomenon has led to feminists calling far changes in the way beauty is perceived in the society so as to alleviate the impeding danger of malnourishment. Recent happenings in some beauty events early this year clearly illustrates the extent to which the problem has become another challenge for governments and other stakeholder such as health departments. Role of media Media has been termed as one of the strongest agent of change in the 21st century. From the internet to television adverts, mobile phones and computer technology. Media in all its forms whether print or electronic is the vehicle through which the society mostly utilizes in communication. For instance, in advertisement, the medial constantly portrays the beautiful women as that who is slim slender or not weighing a lot. Due to its power of communication, audiences often fall for what the media passes across and only a few take the time to review it and give it a critical review. Thus, the media has in some sense been misused to misconstrue facts and there has altered meanings of some concepts such as beauty. On the other hard, media can be used positively to rectify the negative perception inculcated in minds of people especially about what entails beauty. The media can come up with programmes aimed at advancing a different dimension, which perhaps de-emphasises sliminess and concentrates on other aspects such as beauty of the heart as well as beauty of being truly health through use of natural means such as healthy food, and exercises. Role of community/Team In terms of beauty at least every one grows knowing a beautiful colleague. It is hard to fail to arrive at consensus on who is beautiful than, who usually the judgement does not need experts but each society is socially constructed in such a way that, it has attribute and even values which as highly associated with beauty, it is these values than the community and ones peers hold about being beautiful and what is beauty that, make the role of community and peer central to the understanding of beauty. The society especially peers have enhanced the constructing of beauty as thinness is that, even in most cultures, being overweight is more revered than being under weight. This clearly points to the fact that, thinness has been taken to be a synonym for beauty and vice versa. Conclusion As long as society continues to give more power to thinner women, eating disorders will continue. Women are expected to look and act a certain way in order to have a small portion of the power men have. As feminist we must help create a society that avoids discrimination. Eventually that is the only way that we will help alleviate many issues women deal with, such as eating disorders.

Economics Article Commentary Essay Example | Topics and Well Written Essays - 750 words

Economics Article Commentary - Essay Example The author compares East Asian markets like South Korea, Hong Kong, Taiwan and Singapore which have grown under the control of their respective governments. Even the US markets which promote free trade have some participation of the government. Market liberalisation has resulted in adverse effects on the poor in the developing countries. In such countries, agriculture is the main occupation of majority of population. Agriculture sector allows the import of cheap products in the local markets. Small scale farmers of the developing countries like Ghana, Kenya are not able to sell their produce in their own countries and have to pay more for the farm needs. Free trade gives far more powers to the traders outside the country who make sure that in addition to the cheaper imports of their own products, exports of the country are bought at cheaper prices which eventually hits the local agriculture sector. This results in the exploitation of the poor farmers. Small scale farmers are losing their lands to richer sections of the society. Liberalisation is forcing gender inequality and unemployment. Market liberalisation is also affecting the environment. Earlier crops were grown according to soil types and climate. There was a vast diversity of the crops grown all round the year and in different regions. While now the concentration is on the growth of the cash crops fit for the export. Crops that are suitable for export are grown on a large scale affecting the environment conditions resulting from soil degradation and extensive use of chemical fertilizers and pesticides. As government does not interfere, all the support offered by the government to the small scale farmers is also lost such as subsidies, agricultural research, price control and so on. Free trade also hampers the self-sufficiency of a nation on its own production. Traders establish monopoly in the local markets.For overcoming this problem, governments should have selective intervention in the markets. As mentioned earlier East Asian markets like South Korea, Hong Kong, Taiwan and Singapore have benefited from the participation of government in controlling and managing the markets. Government decides the policies and restrictions such as investment tariffs and various taxes to be imposed on the foreign trade in order to protect the domestic trade and attain maximum benefit from the international commerce. Governments tend to maintain price stability and balanced growth keeping in mind the interests of every section of the society. Some of the steps the governments can take are: open an d fund government banks, promote savings, subsidised credit for the industries, investment in technological developments, promotion of export and protection from imports that can affect domestic produce. Governments provide aid to small scale farmers and declining industries. The main focus lies in the capital accumulation and labour literacy. The administration should selectively intervene to control the inflation. Public and private sectors must be able to share the information. Extensive exports and huge foreign investments regulated by government can boost up the economy. These are the steps taken by the governments of East Asian countries that resulted in their miraculous growth. US markets also support free trade but government plays an important role as well. Agriculture sector needs aids from the government and US government provides financial

Strategy and Culture Essay Example | Topics and Well Written Essays - 250 words

Strategy and Culture - Essay Example If the strategy does not fit the culture the organization and its people might experience confusion and uncertainty. If a strategy does not require major changes in the culture of the organization, it may be easy to adopt and it may not even consume ample amount of time. When two organizations join hands together it is very important that the organization pays emphasis to the link between the organization’s culture as well as strategy. For example: The merger of Compaq and HP was quite astonishing as the culture of both the organizations was quite different from each other (Fried, 2002, p.1). HP was focusing on a huge portfolio of products, they spent heavily on inventing new technology, the management style practiced in HP was such that the management was heavily involved in the organization and the decision making process of HP was quite professional in nature. On the other hand Compaq spent less on inventions, they had a smaller portfolio as compared to HP and the managemen t style was dictatorship like in nature because decisions were made on the top level and handed down to the lower level and they took heavy risks. This example clearly shows that there was a misfit between the cultures of the organization and the strategy of merging both the organizations. Fried, I. (2002, September 2).

I Believe In Wisdom Personal Statement Example | Topics and Well Written Essays - 750 words

I Believe In Wisdom - Personal Statement Example   Albeit the confusion of growing up, nothing interesting coming my way that never caught my attention. More often than not, I kept weighing the benefits that each presented in my life. When it hit me that wisdom played a considerable role in my life, I took its stand. Experiences played their part, significantly to influence this stand. This is the one believe that for a long time now has remained with me, stuck with me, and molds the person I am. In planning for my future, wisdom remains the significant factor that I put into consideration. Like a journey, my strong belief in wisdom took a rather long route. When it finally came, I doubtlessly knew where my beliefs lay; in wisdom. At a tender age, the ability of the Biblical Solomon to solve the big case of the two mothers awed me more than it amused me. The reasoning behind his ruling on the case was beyond any judgmental ruling I have ever heard of. On several occasions, I made comparisons of the ruling of my country’s j udges with the Solomon incidence. My aspirations were never on being a legal counsel, neither lawyer. Yet, my reasoning on the different ways in which I could successfully make my own personal ruling and judgments crowded my head. The difference in my way of thinking and that of legal thinking was simple; mine was not vested in any voluminous works I had learnt, or the various cases that I had read and the decisions reached in law school. Any person can make a mistake, but Solomon did not. People acquire knowledge, but wisdom develops. This made my way of thinking different from the legal school of thought, choosing conscious reasoning and thinking. I had a big thirst for sober decisions. Regrets, I suppose, befall poor planners. I did not want to become one. Every time I was faced with a trying problem, I compared this situation, weighed the chances available and thought of their outcomes. This, as I figured, would help me walk through any compromising situation. When one day my yo unger brother started developing a funny character, I put into test my wisdom. His character took a drastic change, as his school grades took a nosedive. He plummeted from a top performing student to a low ranking student. This attracted the attention of his teachers, while my parents became a worried lot. Even with mentorship, monitoring and guidance, he never seemed to change. Physically, he showed no signs of depression or stress. He was as handsome as always, and did not show any signs of weight loss. What baffled many is that while his character kept changing, his friendship never did; he kept the same friends as before. However, he ate lesser quantity of food, slept excess fully, talked less and stopped playing his favorite game, the PlayStation. Counselors thought he was suffering from stress-related problems, while my parents held a rather weird stand; he either was turning gay or was a drug addict. Perhaps his condition compared to either of these perceptions, even all. For me, this was an opportunity to test my wisdom. Wisdom does not rely on tested evidence, but on a well-reasoned decision.

Edvard Munch Research Paper Example | Topics and Well Written Essays - 250 words

Edvard Munch - Research Paper Example His paintings reflect his tragedies and failures that transcribe the reality and record the impact of a personal experience. These pieces of art transmit emotional sensation as a result of the natural contemporary issues. The visionary power is enhanced by the incorporation of the lyrical and romantic aspects in his work. Munch was concerned with expressing humanity and consciousness in art by incorporating the injustices and relationships experienced by living people. The â€Å"Frieze of Life† has the sensation of love between men and women that is a force of nature (20). The painting has a narrative of awakening love that blossoms and withers, and ends with despair and death. The â€Å"Kiss† also depicts a woman and man locked in a passionate embrace. These paintings reflect the reconstituted subjectivity of the natural world where people experience love naturally and the feeling is shattered by death. Love, death, suffering, and illnesses are aspects of the current society illustrated in the work of Munch. The ability to intertwine reality and art has gained Munch popularity in modern

The Emerald Forest Essay Example | Topics and Well Written Essays - 1750 words

The Emerald Forest - Essay Example This cleaning of forests angered the tribes living in the forests known as the Invisible people and The Fierce People (â€Å"The Emerald Forest†). The story gets its real essence when one-day Markhem takes his family for a tour of the forest and his son Tommy gets abducted by the Invisible people (â€Å"The Emerald Forest†). The invisible people are environmental friendly people, who are very close to nature considering it as their friend and living happily in their forest in their own community unless Markhem comes to destroy their peace and take away their home (â€Å"The Emerald Forest†). They kidnap his son because they assume that Westerners or termites as they call them are the destroyers of the world, but the child is innocent and so should not live with these murderers. Tommy is adopted by the chief of the tribe Wanadi who loves and brings him up as his son. Markhem searches a lot for Tommy but does not find him until after ten years when Tommy rescues hi m while fleeing for his life from the Fierce People (â€Å"The Emerald Forest†). Markhem asks Tommy to return to him and his world but Tommy refuses and says that now his world is this forest and his people are his tribe. Markhem even asks their chief Wanadi, who is the authority of the Invisible People to convince Tommy to return but Wanadi says that â€Å"If I tell a man to do what he does not want to do, I may no longer be the chief.† Meaning that even being the authority there he has no right to force people to do something they don’t want to do.... The chief does not give any command or order to his people, not even his son to follow, rather he understands that it is the basic right of every human being to follow his will and wish (â€Å"Proyect†). However in the modern western world, lives of humans are ruled by orders and commandments given sometimes by their parents, sometimes by teachers, later by their employees, and overall by the governments, policemen etc (â€Å"Proyect†). It was not just that there was a wide gap between the authority structures of these two societies but their entire life style, culture, norms, traditions etc all were opposite. The people of the traditional societies still use artillery, spears and arrows to fight and they walk to cover long distances (â€Å"The Emerald Forest†). The use of technology is very limited or almost nonexistent in their lives as they are closer to nature and lives together. In contrast to them, modern western society uses technology to a large extent (à ¢â‚¬Å"The Emerald Forest†). There are modern methods of fighting like machine guns and bombs, aero planes, railways cars etc to travel to far away distances in just hours, large machines are used for construction and to cut off forests. This advancement in technology has both its benefits and costs (â€Å"The Emerald Forest†). With technology comes the easiness to do things and time gets saved in travelling. As Wanadi says to Markhem â€Å"When I was a boy, the edges of the world was very far away, but it comes closer each year.† However with benefits comes the cost too. As more vehicles are produced, so have the pollution from air, land and water increased as well (â€Å"The Emerald Forest†). This pollution is destroying our respiratory system by going inside us

Central line associated bloodstream infections Research Paper

Central line associated bloodstream infections - Research Paper Example It is essential that appropriate steps are taken by both the healthcare providers and the patient to assist in the prevention of such infections. Around 41,000 CLABSI happen within the United States hospitals every year. The central line- associated bloodstream infections are normally severe infections causing in a typical manner, a lengthening of stay in hospital and increased mortality risk as well as financial costs. Central line-bloodstream infections can be avoided by making use of proper techniques of insertion as well as through managing the central line in a proper manner. CVC, or central venous catheters, render essential accession to the bloodstream; all the same, their insertion makes the patients prone to CLABSI. The phases of insertion of central venous catheters and its maintenance afterwards along with the central line-associated bloodstream infections prevention plans may pose a challenging situation to the infection prevention while conveying resources to the central venous catheter phase that is inducing sub-optimal rates of CLABSI. Bloodstream infections that are associated to catheter are linked with the substantially increased mortality, morbidity as well as expenditures. These infections are a source of a severe threat to the patients within the intensive care units. In order to prevent central line-associated bloodstream infections, nurses, doctors and other health care professionals are required to follow the infection prevention guidelines provided by the Center for Disease Control in 2011. They are also needed to follow the recommended insertion techniques for the central line to avoid the risk of infection. The measures and guidelines provided by the CDC in 2011 are an effective way of preventing the occurrence of such infections. Guidelines along with the care bundles also advocate arrangement of care modules on the basis of unit characteristics; incorporating empirical measures and resources; training and education to encourage broa d implementation; and monitoring and auditing to make sure that staff is consistently following the advised procedural guidelines (Lu et al., 2012). The rates of central line-associated bloodstream infections in the ICUs of United States have been observed to decline dramatically in a few years as reported to the National Healthcare Safety Network (NHSN). This remarkable success has been achieved by applying a multifaceted technique and focusing on the use of best evidence-based practices for insertion of central line. Moreover, it has been suggested by the recent research that an additional benefit can be reaped by applying best evidence-based practices for the maintenance of central line. A meta-analysis conducted recently affirms the exercise of CHG, or chlorhexidine gluconate bathing, within the population of ICU in order to prevent CLABSI (Miller & Maragakis, 2012). Central line-associated bloodstream infections are regarded as a preventable problem of health care delivery. Mor eover, due to the utilization of resources and the remarkable morbidity, central line-associated bloodstream infections conduct a traceable mortality within the range of 12 to 25 percent. The approximated cost is around $25,000 per infection. During the

A Retrospect of the Hong Kong Handover Essay Example for Free

A Retrospect of the Hong Kong Handover Essay Slide 2 Hong Kong’s handover to the Chinese government after 150 years of British colonial rule is a major historical event My paper analyzes whether or not China handled Hong Kong well 10 years after the Handover occurred. It also aims to look at the changes that have taken place since the Handover, and how they have affected the situation in Hong Kong. Important questions regarding this issue are:   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   After 10 years, did China handle Hong Kong well?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Has China fulfilled its promise to maintain Hong Kongs status quo as a leader in Asian economy?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Have the policies and changes that the Handover has brought been beneficial to the people of Hong Kong? My position is that China did a good job in the sense that they did not do harm to Hong Kong and was able to preserve the liberal economic and political spirit of the place. My conclusions are based on the following parameters: One, the economic situation of the territory, and two, the political situation of the territory. Slide 3 Background of the Issue Why was the Handover a source of anxiety to Hong Kong citizens?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The Hong Kong way of life is different than that of Mainland Chinas   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   China is under a Communist System while Hong Kong adopts a free market economy The Impact of the Hong Kong handover can be brought to light with the following facts: Geography Hong Kong is a small piece of coastal island below Mainland China. Its strategic location made it an important port for the trading of goods and is regarded as an ideal base for military and tactical operations. When it comes to its economy, Hong Kong is a force to contend with. Hong Kong: Is one the modern world’s most important financial hubs Enjoys one of the world’s highest gross domestic products Provides jobs to millions in Mainland China as well as in neighboring countries Slide 4 Aftermath of the Handover Accounts of life in Hong Kong right after the Handover were promising. Generally, it was â€Å"life as usual†. The general consensus is that the Handover did not cause the major political and economic upheavals that many feared it would. While there was a slowing down in the economy, it was not at the level expected. The changes were milder and subtler than expected The reaction of the business community to the Handover reflects the reaction of the locals: Businesses were able to ride the change without much difficulty. Multinational companies based in Hong Kong have been loyal, and were able to transcend political upheavals. Slide 5 The most important policies implemented after the Handover included â€Å"One country, two policies† and â€Å"Hong Kong people administering Hong Kong†. China also increased public spending and reduced tax. These policies have allowed Hong Kong’s Special Administrative Region (SAR) government a free hand to implement decisions with respect to Hong Kong’s political and economic environment. Such a moves also proved to be effective because it kept businesses in Hong Kong. Hong Kong’s Performance under China’s rule has been on the large part, successful. The following are evidence of China’s good handling of the Hong Kong Handover: Hong Kong was one of the least affected during the Asian economic depressions Hong Kong was one of the first to bounce back from the depression. Hong Kong survived the health problems of SARS, bird flu and mad cow disease.

Early diagnosis of autism and impact on prognosis Essay Example for Free

Early diagnosis of autism and impact on prognosis Essay Autism and IQ Introduction Early diagnosis of autism and impact on prognosis: a narrative review   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Fernell, Eriksson and Gillberg (2013) based the study of the individuals affected by ASD on the magnocellular theory. The theory’s main constructs include that the people suffering from the disorder will have impaired magnocellular transmission networks and that the impairment is the cause of their problems in the processing of information on movement and motion. The theory also explains the problem as one, where results from the abnormal nature of magnocellular neural networks and a variety of sensory systems, unlike in the case of other similar conditions like dyslexia. The main constructs of the theory used by the authors of the article are based on the malfunctioning nature of the networks that guarantee that the working of the human brain is effective and optimal. The main constructs explored under the theory incorporated into the study are related in a variety of ways.Theyinclude the neurodevelopment deficiencies found in the brains of these individuals are the main cause for the impairment of the individual’s social instinct.The article draws on the behaviors that are manifest from the nature of these individuals, to conclude that the impairment of brain networks lead to socially instinctual deficiencies, for example,slowness in flicker-pedestal evaluations. In real life situations, the individual is not able to indicate the appearance of the different squares.Fernell, Eriksson and Gillberg (2013) contended with the premise of the theory that the effects seen arise from physiological underdevelopment of the brain. They also offered the explanation that impaired development or underdevelopment is caused by a variety of medical deficiencies. Based on the research done in a five-year period, they highlighted that there is a wide variety of causes, including the developmental deficiencies, early detection and trials to correct the issue and the effects of treatment. The effects explored included the impairments seen in the social functionality of the child and the outcomes of the treatment plan. For example, one of the effects explained was that there is little evidence of effective results arising from early interventions (Fernell, Eriksson Gillberg, 2013). The article explored a variety of variables that are either moderating or mediating, depending on their nature and levels, including being epileptic and the fragility of the x syndrome. In the working out of the various constructs, the researchers controlled for the outside factors and variables, and reached the conclusion that there is littl e effectiveness in the early intervention models developed. From the study of the meta-analyses of the studies published by Pub Med in last five years. The researchers found some information showing that the adoption of early intensive treatment led to the successful correction of the problems found in children suffering from ASD. The interpretation of the findings was that more study was needed to explore the link between the impaired development of the networks and the intensity of behavioral corrections. Based on the article’s area of study as well as its findings, some information gaps were exposed, including those on whether the mediating variables of epilepsy among others could hold the key to the positive outcomes. The effects of the mediating factors should be explored further, so as to find out whether it will be necessary to develop a new theory incorporating them (Fernell, Eriksson Gillberg, 2013). The main constructs explored under the theory incorporated into the study are related in a variety of ways.Theyinclude the neurodevelopment deficiencies found in the brains of these individuals are the main cause for the impairment of the individual’s social instinct.The article draws on the behaviors that are manifest from the nature of these individuals, to conclude that the impairment of brain networks lead to socially instinctual deficiencies, for example,slowness in flicker-pedestal evaluations. In real life situations, the individual is not able to indicate the appearance of the different squares.Fernell, Eriksson and Gillberg (2013) contended with the premise of the theory that the effects seen arise from physiological underdevelopment of the brain. They also offered the explanation that impaired development or underdevelopment is caused by a variety of medical deficiencies. Based on the research done in a five-year period, they highlighted that there is a wide variety of causes, including the developmental deficiencies, early detection and trials to correct the issue and the effects of treatment. The effects explored included the impairments seen in the social functionality of the child and the outcomes of the treatment plan. For example, one of the effects explained was that there is little evidence of effective results arising from early interventions (Fernell, Eriksson Gillberg, 2013). The article explored a variety of variables that are either moderating or mediating, depending on their nature and levels, including being epileptic and the fragility of the x syndrome. In the working out of the various constructs, the researchers controlled for the outside factors and variables, and reached the conclusion that there is little effectiveness in the early intervention models developed. From the study of the meta-analyses of the studies published by Pub Med in last five years. The researchers found some information showing that the adoption of early intensive treatment led to the successful correction of the problems found in children suffering from ASD. The interpretation of the findings was that more study was needed to explore the link between the impaired development of the networks and the intensity of behavioral corrections. Based on the article’s area of study as well as its findings, some information gaps were exposed, including those on whether the mediating variables of epilepsy among others could hold the key to the positive outcomes. The effects of the mediating factors should be explored further, so as to find out whether it will be necessary to develop a new theory incorporating them (Fernell, Eriksson Gillberg, 2013).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Randomized, controlled trial of an intervention for toddlers with autism: the Early Start Denver Model   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Dawson and colleagues (2010) did a randomized study exploring the effectiveness of the ESDM model of treatment. The ESDM is a developmental model of treatment based on behavioral interventions and is intended to lessen the severity of the effects of the toddlers suffering from ASD. The mediating and moderating areas explored through the study included the age of the children, which ranged from 18 to 30 months. The independent variables of the study included the delivery of ESDM model of treatment, and the dependent variable beingchecked towards theory development was the reduction in the severity of the ASD condition. The theory under exploration was the empathizing-systemizing theoretical model. The main position of the theory is that the children suffering from ASD get fewer scores in adaptive behaviors like empathy as compared to their peers (Dawson et al., 2010). The theory is based on the outlook that the effects of autism limit a chi ld’s ability to adapt to social situations and their environment.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The main constructs of the theory include the systematized nature of social functionality, sensory manipulation, and the working of motor-based systems. The relationship of the constructs is that the impairment in the development of the brain leads to the reduced effectiveness of the autistic child. The cause of the phenomena includes the impairment in the development of the brain. The effects include the low levels of emotional ability (empathy), sensory manipulation including tapping; and motor manipulation like rocking. The mediating variables included the ages of the children and were not demonstrated to have any effect on the effectiveness of the treatment (Dawson et al., 2010). In the operationalization of the constructs, the study used a study group and a control group. The study split the sampled children of ages ranging from 18 to 30 monthsinto two groups (control and study).In addition, it delivered the ESDM treatment over a two-year period and demonstrated that the method yielded results.The study adopted a statistically comparative study of the children’s standardized scores. The study showed that the treatment was effective, and the study contributed to the advancement of the theory that the developmental effects can be reduced. The results of the study could widen the scope of the theory among others as many have maintained the position that treatment does not yield results(Dawson et al., 2010). Systematic Review of Early Intensive Intervention for Autism Spectrum Disorders   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Warren and colleagues (2011)based their study on the theory of applied behavioral evaluation. The main constructs of the theory include that the principle that child learning can be utilized to improve the affected behavioral areas, through behavioral learning. The implications of the principle are that, despite that it may be impossible to solve the problems completely; it is possible to reduce the severity and develop behaviors that reduce their adversity. The relationship between the constructs is based on the outlook that behaviors are learned and that the impaired behavioral areas can be improved through specificallytargeted learning. The learning that is effective for different individuals is often different, depending on the severity of the ASD in the different areas of underdevelopment. The causes in a relationship include the impairments of the children’s brains, and the effects of behavioral training. The mediating factors explored in the study include the outlook of the behavioral training and its effectiveness. The aspects taken into account as determinants of the effectiveness of the process include the team that administers the behavioral training. In the operationalization of the constructs, the study explored the study explored the modeling based on the early start Denver system. The study entailed the review of the literature that explored the field during the years spanning from 2000 and 2010. The study was mainly a literature review of the studies done, in the past, in the area. The study did not apply any statistical analyzes, due to its nature. The findings of the study included that the Lovaas-based model of treatment, among a few other early intensive training for behavioral development, improved skills like language, cognitive abilities, and social behaviors. The interpretation of the results was that early interventionism is useful in countering or lessening the severity of the impacts of ASD. Autism spectrum disorders: an overview of diagnosis andtreatment   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Brentani and colleagues (2013) based their exploration of the problem of ASD and the corrective measures employed to address it, on the developmental milestones of children aged between 0 and 3.The article started by exploring the wide array of developmental impairments that resemble ASD, including a Heller’s syndrome.It emphasized that they all result from the faulty or compromised working of the child’s brain systems(Brentani et al., 2013). The effects of ASD explored include the abnormality of social engagement, creative play, and language skills. The major constructions explored by the authors in the review included the diagnostic models used, main areas of evaluation, the scales and tools for evaluating the problem and the information generated through epidemiological treatment models. In exploring the wide array of constructs, the authors reviewed the studies exploring ASD and the different variables. The relationship b etween the constructs includes that some contribute to the development of ASD The relationship between the constructs includes that some contribute to the development of ASD andothers are the outcomes(Brentani et al., 2013). The causes covered by the study include drugs administered for symptom control and the scales used to evaluate the problem and their effects on the management of the problem. There are no mediating or moderating constructs, but the dependent constructs include the change of the symptoms of ASD. The study was mainly a review of theliterature; therefore, it did not employ any research methods. Using the outcomes of the study, there was no information reported on the recovery of the subjects covered by the study after they were subjected to the corrective and management-based treatments. Further, the study gave the impression that it is necessary to develop multi-professional teams in the exploration of the problem of ASD. In addition to its engagement with management or treatment models (Brentani et al., 2013). Autistic spectrum disorders: Diagnostic and Therapeutic challenges in Mexico   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Marquez-Caraveo and Albores-Gallo (2011)explored the nature of ASD, which are developmental impairments that affect three areas, including the skills of communication, interactive skills in social settings and motor movements. The study explored in the article is based on the developmental theory of mind blindness. The theoretic model that emphasizes the blindness of the mind, is based on the concept that the autism of a child is initially noticed by parents. Among the other people within the social circle of the child as early as when they are as young as 12 months of age.The theory highlights that the areas of cognitive and interactive development that are impaired include the child’s ability to observe the behavior of another and then adjust in response. One example of real-life experience that demonstrates this area of weakness is that you will find the autistic child looking outside the window, but they will notice little on th e view outside the window. In exploring the theory, the researchers highlighted that less than 38% of families seek medical advice, even after noticing the developmental deficiencies that give evidence of ASD. The researchers also highlighted the necessity of training health and educational service providers, on the developmental course of social communication and interactions as well as language acquisition. By developing the experience and the knowledge needed to discover the problems of the children, they will report the condition before it escalates to levels that are more adverse.

The relationship between the various constructs is one that demonstrates a continuum model.This is where the observation of symptoms should lead to the use of dedicated tools to study the problem and initiating psychosocial treatment to reduce the severity of the problem.The cause variable is the symptoms of ASD. The mediating and in some case moderating variable is the evaluation of the problem using dedicated tools. The dependent variable is initiating psychosocial treatment, which leads to the reduction of the problem. The constructs were mainly explored as a continuum of events, and not operationalized as cause-effect based phenomena.

Application Of Types Of Lubricant

Application Of Types Of Lubricant A lubricant is a substance (often a liquid) introduced between two moving surfaces to reduce the friction between them, improving efficiency and reducing wear. They may also have the function of dissolving or transporting foreign particles and of distributing heat. Basically there are many types of lubricants; solid lubricant, liquid lubricant and gaseous lubricant. They have their own purpose and application. They are as follows: Purposes: Almost all the Lubricants perform the following key functions. Keep moving parts apart Reduce friction Transfer heat Carry away contaminants debris Transmit power Protect against wear Prevent corrosion Seal for gasses Stop the risk of smoke and fire of objects Applications: Application of Semisolid and Solid Lubricants Grease lubricants are semisolid and have several important advantages: They resist being squeezed out, they are useful under heavy load conditions and in inaccessible parts where the supply of lubricant cannot easily be renewed, and they tend to form a crust that prevents the entry of dirt or grit between contact surfaces. Grease is a mixture of a lubricant and a thickener; often it is made from a mineral oil and a soap. It may be applied in various ways: by packing enclosed parts with it, by pressing it onto moving parts from an adjacent well, by forcing it through grease cups by a spring device, and by pumping it through pressure guns. Solid lubricants are especially useful at high and low temperatures, in high vacuums, and in other applications where oil is not suitable; common solid lubricants are graphite and molybdenum disulfide. Application of Liquid Lubricants Liquid lubricants may be characterized in many different ways. One of the most common ways is by the type of base oil used. Following are the most common types. Lanolin (wool grease, natural water repellant) Water Mineral oils Vegetable (natural oil) Synthetic oils Other liquids Mechanical devices to supply lubricants are called lubricators. A simple form of lubricator is a container mounted over a bearing or other part and provided with a hole or an adjustable valve through which the lubricant is gravity-fed at the desired rate of flow. Wick-feed oilers are placed under moving parts, and by pressing against them they feed oil by capillary action. Horizontal bearings are frequently oiled by a rotating ring or chain that carries oil from a reservoir in the bearing housing and distributes it along the bearing through grooves or channels. Bath oiling is useful where an oil-tight reservoir can be provided in which the bearing journal may be submerged; the pool of oil helps to carry away heat from contact surfaces. Splash-oiling devices are used where gears, bearings, or other parts contained in housings have moving parts that dip into the lubricant and splash it on the bearings or into distribution channels. Centralized oiling systems usually consist of a reserv oir, pump, and tubes through which oil is circulated, while heaters or coolers may be introduced to change the viscosity of the lubricant for various parts of the system. Many oiling operations are automatically synchronized to start and stop with the machinery. P2) Describe the operation and maintenance of three different lubrication systems. Oil lubricating systems can be divided into three categories: Total loss. Self contained. Re-circulating. Total loss: lubrication points are always supplied with fresh lubricant (oil, fluid grease or grease) at specific intervals (time or machine cycle-dependent) during the lubricating cycle. It is the only system that allows the lubricating oil to drain away or evaporate. Self contained : With self contained lubrication, the oil is contained in a reservoir. A gearbox of a vehicle or a lathe is lubricated in this way. The gear are partly submerged in the oil, this process is called splash lubrication. Oil is carried up to the parts that are not submerged, and an oil mist is created inside the gearbox. Ring oiling is another self contained system in which the oil from a reservoir is carried up to the rotating parts of a mechanism. The ring which is rotating with a shaft is partly submerged in the oil and carries it up to the shaft bearings. Re-circulating: With re-circulating system, the oil from a reservoir is fed under pressure direct to the moving parts or delivered as a spray. The flow is continuous and after passing over the contact surfaces, the oil runs back into the reservoir under the effects of gravity. Maintainance: Oil lubrication systems should be checked weekly. This can be carried out by plant operators or maintenance engineering. If needed the tank or reservoir can be topped up taking care not to let any dirt into the system during the process. Systems should not be overfilled as this might caused increases resistance to splash lubricated parts. It might also lead up to overheating of the oil due to excessive churning. Dip sticks and sight gauges are usually provided to indicate the correct level or depth in reservoirs. Samples of lubricating oil are taken for laboratory analysis at regular intervals as part of a condition monitoring procedure. They are examined to see if they contain any solid wear particles. This can provide useful information to the plant manager and maintenance engineer as to the condition of the plant and machinery. All lubricating oils degrade over a period of time due to oxidation. They should be changed including the filters in a re-circulating system. Human should be careful of lubricating oils, since it can cause skin irritation, it can also lead up to cancer. So humans should always use safety equipments and should also wear protective clothing and maybe goggles for the eyes, when handling lubricating oils. References: http://en.wikipedia.org/wiki/Lubricant, engineering book P3) Describe the operation of one seal, one type of packing and two different types of bearing with a typical application for each one. Seals: For the task , I will be doing oil seal. Oil seals are flange packing having an elastomer lip bonded to a metal cup, these lips are loaded to accommodate shaft running out and helps in sealing. There are two types of oil seals. Single seals , which are recommended only for non-pressure service and are best against good lubricating media. And the other one is double sealing, which are normally used to handle pressure in eiher direction along the shaft. The main function of oil seal is to stop whatever fluid is inside from leaking out the clearance between the shaft and housing. Packing For packing, I will be explaining about gland packing seals. they are usually made of cotton, asbestos, flax or jute. In this packing, compressed synthetic fibers are also used and sometimes impregnated with graphite to assist lubrication. It has the advantage to withstand higher internal pressures than lip seals. in this packing, a collar is tightened so that packing material forms a seal around the shaft. A little amount of water for lubrication and cooling the packing is also allowed to drip to the atmosphere. It is normally used as a seal for both rotating and reciprocating shafts. Bearing: The purpose of the bearing is to support and locate rotating and reciprocating shafts or parts in machines and is to transmit force from one member to the other while allowing their relative motion/ movement to occur with the minimum resistance to motion. Two bearing I will choose for this task are plain bearing and roller bearing. Plain bearing: it is a typical bearing made of two parts. For e.g. a rotary plain bearing can be just a shaft through hole. A simple bearing can be pair of flat designed to allow motion. It has flat , cylindrical or spherical surfaces which slide relative to each other. It can be used to carry load in one of several ways depending on their operating conditions, surface, clearance and temperature. It may be used to comprise a rotating collar with a flat surface loaded against a plain or grooved thrust ring. It is also designed to withstand the forcve acting along the axis of the shaft, parallel to the axis of rotation. Roller bearing: this bearing carries a load by placing round elements between the two pieces. The relative motion of the pieces causes the round elements to roll with very little rolling resistance and with little sliding. A rolling element rotary bearing uses a shaft a much larger hole and cylinders called rollers tightly fill the space between shaft and hole. The bearing are often used for axles due to their low rolling friction. References: handout given by teachers P4) Describe two different types of screwed fastening and two different types of rivet giving a typical application for each one. Screwed fastening are used to make semi permanent joints which allow access and removal of fastened parts for maintenance and/or repairs. There are many types of screwed fastening of which the two I am going to mention here are nuts and studs and set screws. stud and nuts: it is a length of bar which has been threaded at each end, the shorter threaded end is screwed into the major component. It is used for inspecting machine cover needs to be removed regularly for maintenance purpose. Set screws: it is also known as machine screws however it does not used a nut. It is usually used to join a thin plate to a larger component. Screws are available with different shapes of head for different applications. It can be used as locking devices. P6)Describe the arrangement and operation of two different kinds of belt drive, two different kinds of chain drive and two different kinds of gear train. A) Belt drive: A belt drive is a method of transferring rotary motion between two shafts. A belt drive includes one pulley on each shaft and one or more continuous belts over the two pulleys. The motion of the driving pulley is, generally, transferred to the driven pulley via the friction between the belt and the pulley. Synchronous/timing belts have teeth and therefore do not depend on friction. Belt drives and gear transmissions have a much greater life expectancy than belt drives. Belt drives also have relatively high inspection and maintenance demands. There are many types of belt in which I am going to explain two of them; 1) Round belts Round belts are a circular cross section belt designed to run in a pulley with a circular (or near circular) groove. They are for use in low torque situations and may be purchased in various lengths or cut to length and joined, either by a staple, gluing or welding (in the case of polyurethane). Early sewing machines utilized a leather belt, joined either by a metal staple or glued, to great effect. 2) Ribbed belt A ribbed belt is a power transmission belt featuring lengthwise grooves. It operates from contact between the ribs of the belt and the grooves in the pulley. Its single-piece structure it reported to offer an even distribution of tension across the width of the pulley where the belt is in contact, a power range up to 600 kW, a high speed ratio, serpentine drives (possibility to drive off the back of the belt), long life, stability and homogeneity of the drive tension, and reduced vibration. The ribbed belt may be fitted on various applications : compressors, fitness bikes, agricultural machinery, food mixers, washing machines, lawn mowers, etc B) Chain drive: Device widely used for the transmission of power where shafts are separated at distances greater than that for which gears are practical. In such cases, sprockets (wheels with teeth shaped to mesh with a chain) take the place of gears and drive one another by means of a chain passing over the sprocket teeth. The chains used in conveyor belts are commonly block chains, and consist of solid or laminated blocks connected by side plates and pins. The blocks engage with teeth on sprocket wheels. Depending on the material being moved, buckets, hooks, or other devices are connected to the blocks. 1) Roller Chain: Motion transmitted using shaft mounted sprockets. Simplex chain consists of length of single links, duplex is length of double links, triplex is length of triple links. Chain drives should ideally be lubricated and regularly cleaned . However experience shows that this drive method will work for long periods without lubrication or maintenance 2) Inverted Tooth: Also called silent. Motion transferred via shaft mounted pinions (similar to gear wheels.) Higher power power capacities, higher speeds and smoother operation. These drive system definitely requires lubrication. (Oil bath, or spray.) C) Gear train: A combination of two or more gears used to transmit motion between two rotating shafts or between a shaft and a slide. It is a set or system of gears arranged to transfer rotational torque from one part of a mechanical system to another. 1) Simple Gear Train:It is made of few components, a small gear at the centre called the sun, several medium sized gears called the planets and a large external gear called the ring gear. The planet gear rolls and revolves about the sun gear and the ring gear rolls on the planet gear. 2) Simple Gear Train:The most common of the gear train is the gear pair connecting parallel shafts. The teeth of this type can be spur, helical or herringbone. The angular velocity is simply the reverse of the tooth ratio. The main limitation of a simple gear train is that the maximum speed change ratio is 10:1. For larger ratio, large size of gear trains are required. The sprockets and chain in the bicycle is an example of simple gear train. P7 Describe the arrangement and operation of two different kinds of transmission shaft and coupling, two different kinds of clutch and two different kinds of brake transmission shaft rotating shaft that transmits rotary motion from the engine to the differential Different types of shafts: Plain transmission Stepped shaft Machine tool spindle Railway rotating axle Non-rotating axle Crankshaft Propeller shaft Crankshaft The crankshaft is that part of an engine which converts linear piston motion into rotation. The crank and connecting rod mechanism was first used in Roman water mills, to convert the reciprocating motion into rotation, the crankshaft has crank throws or crankpins. More than one piston is attached to the crank to provide a smoother delivery of power to the rotating part, though many small engines such as those found in garden machinery, use only a single piston. The configuration of pistons in relation to each other and the crank and their number leads to descriptions such as straight-4 (four pistons in direct line), V6 or V8. Transmission shafts sizes vary from 10 to 100mm but it can go higher then these figures, the maximum length of shaft usually does not exceed 7m. Propeller shaft Propeller shafts transmit power between the source and the machine, the propeller shaft assembly consists of a propeller shaft, a slip joint, and one or more universal joints. This assembly provides a flexible connection through which power is transmitted from the transmission to the live axle. Axle is similar in shape to the shaft and support bending movements only. The propeller shaft may be solid or tubular. A solid shaft is stronger than a hollow or tubular shaft of the same diameter, but a hollow shaft is stronger than a solid shaft of the same weight. A slip joint is put at one end of the propeller shaft to take care of end play. The driving axle, attached to the springs, is free to move up and down, while the transmission is attached to the frame and cannot move. Couplings A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By using couplings, savings can be made in reduced maintenance costs and downtime. Thompson coupling Thompson coupling is a constant velocity universal joint that can be loaded axially and continue to maintain constant velocity over a range of input and output shaft angles with low friction and vibration. It consists of two cardan joints assembled within each other, so eliminating the intermediate shaft along with a control yoke that geometrically constrains their alignment. The use of cardan joints within the Thompson Coupling is to reduce the wear, heat and friction. The Oldham coupling The Oldham coupling transmits rotary motion between shafts that are parallel but not always in perfect alignment. Oldham couplings consist of three members, a floating member is trapped by 90 displaced grooves between the two outer members which connect to the drive shafts. Oldham couplings can bear lateral shaft misalignments up to 10% of nominal shaft diameters and up to 3 angular misalignments. Clutch: A clutch is a mechanism for transmitting rotation, which can be engaged and disengaged. Clutches are useful in devices that have two rotating shafts. In these devices, one shaft is typically driven by a motor or pulley, and the other shaft drives another device. Friction clutch: it connects two separate pieces of shaft, it also has levers and springs to disengage/engage plates. The primary disadvantage of friction clutches is the regular maintenance and adjustment that are required, mating parts will wear due to friction (resulting in slippage), springs will lose memory, and other parts will need replacement or adjustment. Positive clutch: A clutch designed to transmit torque without slip. It consists of two mating surfaces with interconnecting elements, such as teeth, that lock together during engagement to prevent slipping. Positive clutches are also known as mechanical lockup clutches. Brake: A specific type of clutch that slows and stops motion by engaging a rotating shaft and a fixed component. Disc brake The disc brake or disk brake is a device for slowing or stopping the rotation of a wheel. A brake disc (or rotor in U.S. English), usually made of cast iron or ceramic composites (including carbon, Kevlar and silica), is connected to the wheel and/or the axle. To stop the wheel, friction material in the form of brake pads (mounted on a device called a brake caliper) is forced mechanically, hydraulically, pneumatically or electromagnetically against both sides of the disc. Friction causes the disc and attached wheel to slow or stop. Brakes (both disc and drum) convert friction to heat, but if the brakes get too hot, they will cease to work because they cannot dissipate enough heat. This condition of failure is known as brake fade. Hydraulic brake The hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing ethylene glycol, to transfer pressure from the controlling unit, which is usually near the operator of the vehicle, to the actual brake mechanism, which is usually at or near the wheel of the vehicle. P8 Describe with the aid of diagrams the general layout and operation of a pneumatic actuation system, a hydraulic actuation system and a mechanical handling system Pneumatic autuation system: A pneumatic actuation system is capable of directing an amount of fluid to the contained volume such that a pressure within the contained volume exceeds a pressure external to the contained volume by a predefined positive pressure. With the pressure controller, It can also adjust the pressure within the contained volume when the pressure external to the contained volume changes. The educator can draw fluid from the contained volume to thereby decrease the pressure within the contained volume. The valve is controllably operable in either a pressure mode or a vacuum mode, where the valve either permits the pressure controller to provide fluid to the contained volume, or permits the educator to draw fluid from the contained volume. As such, the system provides precision pressure control over a broad range of external pressures while compensating for rapid pressure changes. Fig. example of pneumatic aculator. Hydraulic actuation system: A hydraulic system for a sterndrive marine propulsion device directs the flow of hydraulic fluid through the body and peripheral components of a gimbal ring in order to reduce the number and length of flexible hydraulic conduits necessary to conduct pressurized hydraulic fluid from a pump to one or more hydraulic cylinders used to control the trim or tilt of a marine drive unit relative to a gimbal housing. Mechanical handling system: Mechanical handling is simply a row of roller/cylindrical or triangle cross-sectional component. They are mostly covered by a long belt but it is not necessary. The rollers or what ever it is used are rotating and the product/component will be moving along and the other rollers will pull it along like the image is shown below. The component/product will move until it reaches its destination or the end of the roller P9 Describe with the aid of diagrams the general layout and operation of a steam power generation plant, a refrigeration system and an air conditioning system. refrigeration system BASIC REFRIGERATION PRINCIPLES If you were to place a hot cup of coffee on a table and leave it for a while, the heat in the coffee would be transferred to the materials in contact with the coffee, i.e. the cup, the table and the surrounding air. As the heat is transferred, the coffee in time cools. Using the same principle, refrigeration works by removing heat from a product and transferring that heat to the outside air. REFRIGERATION SYSTEM COMPONENTS There are five basic components of a refrigeration system, these are: Evaporator Compressor Condenser Expansion Valve Refrigerant; to conduct the heat from the product In order for the refrigeration cycle to operate successfully each component must be present within the refrigeration system. The Evaporator The purpose of the evaporator is to remove unwanted heat from the product, via the liquid refrigerant. The liquid refrigerant contained within the evaporator is boiling at a low-pressure. The level of this pressure is determined by two factors: The rate at which the heat is absorbed from the product to the liquid refrigerant in the evaporator The rate at which the low-pressure vapour is removed from the evaporator by the compressor To enable the transfer of heat, the temperature of the liquid refrigerant must be lower than the temperature of the product being cooled. Once transferred, the liquid refrigerant is drawn from the evaporator by the compressor via the suction line. When leaving the evaporator coil the liquid refrigerant is in vapour form. The Compressor The purpose of the compressor is to draw the low-temperature, low-pressure vapour from the evaporator via the suction line. Once drawn, the vapour is compressed. When vapour is compressed it rises in temperature. Therefore, the compressor transforms the vapour from a low-temperature vapour to a high-temperature vapour, in turn increasing the pressure. The vapour is then released from the compressor in to the discharge line. The Condenser The purpose of the condenser is to extract heat from the refrigerant to the outside air. The condenser is usually installed on the reinforced roof of the building, which enables the transfer of heat. Fans mounted above the condenser unit are used to draw air through the condenser coils.The temperature of the high-pressure vapour determines the temperature at which the condensation begins. As heat has to flow from the condenser to the air, the condensation temperature must be higher than that of the air; usually between 12Â °C and -1Â °C. The high-pressure vapour within the condenser is then cooled to the point where it becomes a liquid refrigerant once more, whilst retaining some heat. The liquid refrigerant then flows from the condenser in to the liquid line. The Expansion Valve Within the refrigeration system, the expansion valve is located at the end of the liquid line, before the evaporator. The high-pressure liquid reaches the expansion valve, having come from the condenser. The valve then reduces the pressure of the refrigerant as it passes through the orifice, which is located inside the valve. On reducing the pressure, the temperature of the refrigerant also decreases to a level below the surrounding air. This low-pressure, low-temperature liquid is then pumped in to the evaporator M1) . Compare and contrast the operation and uses of flat plate clutches, centrifugal clutches and fluid couplings in mechanical power transmission systems flat plate clutches centrifugal clutches fluid couplings The fluid coupling is operated simply by a hydraulic fluid and the driver bladed wheel. The driver wheel rotates and rotates the fluid in between follows it along and cause the driven bladed wheel to rotate along the hydraulic fluid. The hydraulic and driven bladed wheel are still under motion even if the driver bladed wheel stops. The friction disc is sandwiched between the machined surfaces of the flywheel and the pressure plate when the pressure plate is bolted to the outer edge of the flywheel face. The clamping force on the friction facings is provided by the diaphragm spring. Unloaded, it is a dished shape. As the pressure plate cover tightens, it pivots on its fulcrum rings, and flattens out to exert a force on the pressure plate, and the facings. It is used in gears, turbine and many more. A clutch operated by centrifugal force from the speed of rotation of a shaft, as when heavy expanding friction shoes act on the internal surface of a rim clutch, or a flyball-type mechanism is used to activate clutching surfaces on cones and disks. Weights wherein each weight has an arc-shaped clutch shoe and is pivotally mounted with a lever foot on a carrier disc on the drive end of the clutch. After reaching a specific rpm, the clutch shoes are pressed under the action of centrifugal force against the inner wall surface of a clutch drum for providing friction-tight torque transmission. The clutch drum surrounds the clutch shoes. The centrifugal clutch includes a carrier disc on which the centrifugal weights are pivotally mounted. A cover disc is held axially tight at the sides of the centrifugal weights which lie opposite the carrier disc. This cover disc radially covers the clutch shoes so that axial guide play is provided. It is used in generators. Device used to transmit rotating mechanical power. It has been used in automobile transmissions as an alternative to a mechanical clutch. There is no mechanical interconnection between the impeller and the rotor (i.e. the driving and driven units) and the power is transmitted by virtue of the fluid filled in the coupling. The impeller when rotated by the prime mover imparts velocity and energy to the fluid, which is converted into mechanical energy in the rotor thus rotating it. It is used n aviation, engineering companies and many more. M2) Compare and contrast the operation and use of pneumatic and hydraulic actuation systems Pneumatic autuation system: A pneumatic actuation system is capable of directing an amount of fluid to the contained volume such that a pressure within the contained volume exceeds a pressure external to the contained volume by a predefined positive pressure. With the pressure controller, It can also adjust the pressure within the contained volume when the pressure external to the contained volume changes. The educator can draw fluid from the contained volume to thereby decrease the pressure within the contained volume. The valve is controllably operable in either a pressure mode or a vacuum mode, where the valve either permits the pressure controller to provide fluid to the contained volume, or permits the educator to draw fluid from the contained volume. As such, the system provides precision pressure control over a broad range of external pressures while compensating for rapid pressure changes. pneumatic actuator system provides the advantage of lower weight and more economical construction. One distinct adv antage of a pneumatic system is that it may utilize a source of bottled gas or the like as a potential energypower source. Fig. example of pneumatic aculator. Hydraulic actuation system: A hydraulic system for a sterndrive marine propulsion device directs the flow of hydraulic fluid through the body and peripheral components of a gimbal ring in order to reduce the number and length of flexible hydraulic conduits necessary to conduct pressurized hydraulic fluid from a pump to one or more hydraulic cylinders used to control the trim or tilt of a marine drive unit relative to a gimbal housing. advantages of pneumatic acutators over hydruallic actuators Relatively cheaper. The force transmitter, air, is freely available. Cleaner system as air leakage do not create a mess. Hydraulic oil becomes very hot after continuous use. Can cause injury if someone comes in contact. Generally have open circuits and we dont have to worry about the return circuit. Justify the use of Shell Tellus oil 27 lubricant and the splash lubrication system in the lathe machines in the College machine shop. Shell Tellus Oils oil 27 are premium quality hydraulic oils generally acknowledged to be the standard-setter in the field of engineering hydraulic and fluid power lubrication. The Shell Tellus oil 27 lubricants are mineral oils.It has an active anti-corrosion additive effectively protects hydraulic systems from corrosion. Water collects in the lubrication system due to condensation with soluble cutting fluid and is emulsified to provide further protection. It has excellent anti wear which means that lathe machine can be used for longer unlike other lubricants, it also helps improve the efficiency of filtration systems to reach system cleanliness targets.The dirt can also clean easily off. The lubricant provides anti-war and increase the resistance of the lathe material surface. It also helps to operate under high temperature; actually it works as a coolant. The lubricant also does a quick air release without excessive foaming. Other point is that the lubricant has very low environmental impact because of the zinc free technology. It also doesnt react with other chemical when it is in use. Shell tellus oil 27 has high lubrication properties and excellent low friction characteristics in hydraulic systems operating at low or high speed. Prevents stick-slip problems in critical applications enabling very fine control of machinery.

What impressions have you formed of the narrator? How has Atwood created :: English Literature

What impressions have you formed of the narrator? How has Atwood created these impressions? Give detailed evidence for your answer - The Handmaid's Tale What impressions have you formed of the narrator? How has Atwood created these impressions? Give detailed evidence for your answer The narrator of 'The Handmaid's Tale' is a woman who calls herself Offred. This is not her real name, but a name that she has been given by the particular husband and wife she is staying with. This makes the narrator seem mysterious, and Atwood creates this impression by not telling us the narrator's real name. From the very start of the novel, Offred has given me the impression that she is quite well educated by the way she speaks and expresses things 'like the place in a face where the eye has been taken out'. This type of simile, which she uses also, gives us the impression that she isn't very happy about her surroundings because she is using violent expressions and associating things, which are supposed to be quite pleasant to things that sound very disturbing and of a violent nature. 'Clouds like headless sheep', normally clouds are associated with bright fluffy marshmallows and pleasant things like that, but the narrator sees the clouds in the sky as disturbing images. All of the way through the book she uses simile's like this to compare normal looking objects or people. 'The smile of blood' is the phrase she uses in chapter six, when she is describing the men, which are hanging on the Wall. The phrase 'The smile of blood' is referring to a stain of blood which has seeped through the white cloth which is covering up the mans face, and she is saying it appears to look like a smile which a child has drawn. This seems disturbing because smiles are meant to represent happiness in people, and she turns that happiness sinister with saying it is a smile made of blood. Also this phrase makes us think about why it would be a smile, rather than and unhappy face, because of him being dead. These violent associations certainly indicates to us that the narrator is unhappy, and that is exactly why Atwood created that quality about her, so that we know that Offred is not happy about the situation she is in at all, and that she relates to violence a lot of the time because she is used to seeing violence going on around her. At the very start of the novel the narrator was continuously slipping in and out of the present tense, she would often talk in the past

Problem Television Programs :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚   Problem Programs Robert MacNeil began his article the, â€Å"The Trouble With Television,† with the overwhelming statistic that the average television viewer squanders one thousand hours per year watching television programming (MacNeil). One thousand hours is a tremendous amount of time squandered watching programs with unchallenging content, this time could be better spent earning a college degree or perhaps earning various languages (MacNeil). I concur with MacNeil that television does â€Å"discourage concentration and applied effort† for the reason that viewers spend an excessive amount of time watching unsophisticated and undemanding programming rather then engaging in activities that will further develop the viewer’s critical thinking. In MacNeil’s article he asserts that viewers waste an excessive amount of tome watching television that is brief and unchallenging. He also adds that programmers deliberately create brief and rousing programs in hopes of achieving the goal of exposing viewers to their advertisements so that a profitable outcome can be reached. MacNeil informs his readers that approximately thirty million adults are functionally illiterate in America, meaning that thirty million adults are unable to read past the fifth grade level. He does not go as far as to say that television is to blame for this outcome, but he does   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Cascarano 2 believe that television contributes significantly to the misfortune. MacNeil also insinuates that viewers are attracted to simple and quick resolutions for many of today’s complex problems in these one half hour shows. Complex problems and quick, easy solutions are often found in these ine half hour comedy sitcoms such as Home Improvement. In a recent episode eighteen year old Brad (the eldest son) confronted his parents about his plans to marry his girlfriend of two months. Brad was convinced that he and his girlfriend wer in live and that was all that they needed to survive. Jill (Brad’s mother) turned to Wilson (their neighbor) for advice. He gives a simple resolution to a complicated problem: reverse psychology. Within a matter of four minutes the problem had vanquished, the young couple would wait until they had both completed four-year at a commendable university. Although quite witty, this simplistic one half hour comical sitcom is not challenging and it does not develop the viewer’s critical thinking because it does not break down the problem and explain a sophisticated and real resolution. Real resolutions are not given in these types of short sitcoms because real resolutions are lengthy and do not keep viewers watching.

An Analysis of a Totalitarian Society Essay

â€Å"Totalitarianism: Of, relating to, being, or imposing a form of government in which the political authority exercises absolute and centralized control over all aspects of life, the individual is subordinated to the state, and opposing political and cultural expression is suppressed,† (dictionary.com). Essentially, totalitarianism is a type of government in which the person or people in power seek to maintain absolute control over every person under their authority, with virtually all importance eliminated from the concept of an individual. The term was characterized by Hannah Arendt, the German-American political theorist who wrote The Origins of Totalitarianism, inspired by Hitler and Stalin of the just-finished World War II and just-starting Cold War. Responding to the terrors of WWII that she experienced firsthand, Arendt describes the evils of totalitarianism as she saw them. George Orwell, an author living at the same time as Arendt, responded similarly to the widespread war and terrifying totalitarianism. In his 1984, Orwell creates a strictly totalitarian society, offering an alarming glimpse into a possible future. Orwell’s society shows every characteristic named above in the definition of totalitarianism, its government’s sole goal to maintain power. The society of 1984 functioned on the belief that control over the human mind is control over reality. As O’Brien, an important member of the Orwellian government referred to as the Party, says, â€Å"Reality is not external. Reality exists in the human mind, and nowhere else. Not in the individual mind, which can make mistakes, and in any case soon perishes; only in the mind of the Party, which is collective and immortal. Whatever the Party holds to be truth is truth. It is impossible to see reality except by looking through the eyes of the Party,† (205). The Party is not concerned with objective facts. They argue that reality can only become reality when it is believed; additionally, the believed reality is the only reality. When O’Brien tells Winston that 2 plus 2 equals five, Winston must believe it, for he is not permitted any other option. Expanding on that idea, the Party states, â€Å"Who controls the past controls the future; who controls the present controls the past,† (204). Only the present out of the three times is tangible, so the others do not really exist. And since reality exists only in the human mind, the Party has only to control the thoughts of that mind to control the  reality of past, present, and future. In their attempt to control the human mind, the Party seeks to eliminate all thoughtcrime, the crime of thinking anything against the infallible Big Brother, the intangible being by which everything is ordered. The act of thinking about committing a crime is, as Orwell describes it, â€Å"the essential crime that contained all others in itself,† (19). That action is considered by the Party the most horrible, for only with thought and a conscious decision to take action will any action be performed; without thoughtcrime, no crime would be committed. As such, the Party utilizes every possible method of eliminating thoughtcrime. Winston Smith, the main character in 1984, commits a thoughtcrime at the beginning of the book when he purchases a diary and in it writes, â€Å"Down with Big Brother,† (19). He then reflects on the inevitable consequences of his action: â€Å"Whether he went on with the diary, or whether he did not go on with it, made no difference. The Thought Police would get him just the same,† (19). The Party has the power to realize any committed thoughtcrime and to punish the criminal. Their ability to do so is even seen in the language; the English language is developed to satisfy the ideological needs of the society, creating Newspeak. One man says, † ‘Don’t you see that the whole aim of Newspeak is to narrow the range of thought? In the end we shall make thoughtcrime literally impossible, because there will be no words in which to express it,† (46). Without fail, the Party maintains their control over all of the society. In order to follow the society conceived in 1984, a method of thinking is absolutely essential; the action of doublethink. Doublethink is a method of reality control; the Party’s ultimate goal in all their actions. As Orwell describes it, â€Å"Doublethink means the power of holding two contradictory beliefs in one’s mind simultaneously, and accepting both of them,† (176). It is the principle on which Ingsoc (the society of 1984) is founded. Ingsoc’s basic tenets are as follows: War is Peace, Freedom is Slavery, and Ignorance is Strength. It is possible to deliberately speak a lie while firmly believing in what one says- through doublethink. One’s memory can be  rearranged and memory altered- through doublethink. Though to our unenlightened minds these terms may seem to be contradictory, the process of doublethink eliminates all confusion. Clearly, these statements are far from oxymorons; rather, they are absolute truth. Doublethink allows for all of the society’s actions that would otherwise seem to be ridiculous; once again, the Party’s ultimate power is revealed. The Party’s absolute control is maintained through various methods, one such being the infliction of threats and pain. Every member of the society knows that once a thoughtcrime is committed, that criminal is taken by the Thought Police. When Winston is arrested, he is able to experience firsthand the punishment constructed by the Party. He is taken to the Ministry of Love- an instance of Newspeak’s use, the meaning of love is utterly reversed- where he is to be made sane. The Party fully believes in the importance and rightness of their actions, and O’Brien explains how their society is different: † ‘We are not content with negative obedience, nor even with the most abject submission. When finally you surrender to us, it must be of your own free will†¦Everyone is washed clean,’ † (210). Winston must fully surrender to O’Brien. It does not matter what he says, but rather what he believes, for in the mind lies the ultimate powe r. Describing the process enacted in the Ministry of Love, O’Brien says, † ‘There are three stages in your reintegration†¦There is learning, there is understanding, and there is acceptance,† (215). In order to attain the state desired by the Party, one deemed mentally deranged must undergo all three of these stages, as Winston eventually does. However, Winston initially is unable to truly believe everything said by the Party. He is able to say that he believes, and perhaps wants to believe, but doubt still remains. As the final push to belief, Winston is taken to the infamous Room 101. O’Brien tells Winston, † ‘The thing that is in Room 101 is the worst thing in the world†¦[it]varies from individual to individual,’ † (233). The greatest possible torture is individualized, and with this torture, comes anything. In Room 101, one is forced to face his greatest fear. Out of his absolute terror, Winston betrays the one he vowed never to betray- Julia, the girl with whom he had a love affair. He finally realizes that love of a fellow common person like himself is futile; only the love of Big Brother is important. At the end of  the book, Orwell writes, â€Å"He had won the victory over himself. He loved Big Brother,† (245). Ultimately, the absolute power of the Party allows Winston t o believe in everything that society does. Realizing the importance of the human mind, the Party not only threatens the society, but also channels the people’s potential into actions to benefit the Party. At all times, Oceania is at war with either Eurasia or Eastasia. It is not certain whether war actually exists, but the actual fact is not important, for reality exists only in the mind, and the Party tells us that a war is occurring. In doing so, the Party assures themselves of ultimate faithfulness from the society, for anyone to go against a society in wartime must surely be denounced as unpatriotic. Furthermore, the Party institutes the Hate Period: for two minutes every day, a film of Emmanuel Goldstein, the pronounced Enemy of the People, is shown, and the viewers driven to a frenzy. As Winston declares, â€Å"The horrible thing about the Two Minutes Hate was not that one was obliged to act a part, but that it was impossible to avoid joining in,† (12). By utilizing the power of the human mind, the Party is able to further their control over their society. The society created in Orwell’s 1984 was undoubtedly an effective society, but the qualities held by that society go against all principles which we now hold to be essential to life. We assume that we have the right to freedom of speech, and that our language cannot be corrupted, yet Orwell says, â€Å"Political language- and with variations this is ture of all political parties, from Conservatives to Anarchists- is designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind,† (â€Å"Politics and the English Language†). We assume that we have the right to challenge anything, yet Orwell tells us, â€Å"Anyone who challenges the prevailing orthodoxy finds himself silenced with surprising effectiveness. A genuinely unfashionable opinion is almost never given a fair hearing.† Today, Orwell’s terms- Big Brother, doublethink, newspeak, and others- are heard when discussing our own government. Though 1984 is a fictious story written over 50 years ago, its message is still relevant today. We all must realize Orwell’s warning  that he sought to make clear over half a century ago- at any time, we all face a common danger; that of conforming; that of losing our individuality, our thoughts, and all qualities valued in humanity.

Prophet Muhammad as Role Model for Religious Teachers

ENGLISH ESSAY: PROPHET MUHAMMAD (PBUH) AS A ROLE MODEL FOR RELIGIOUS TEACHERS Prophet Muhammad (PBUH) is the example par excellence for his ummah, especially for religious teachers with his good example and noble personality. His behavior in all cases is the behavior that is not contrary with the Qur'an, in fact his behavior reflects the contents of the Qur'an such as his patient, sincere and forgiving character. In education, Prophet Muhammad (PBUH) has provided many lessons especially for religious teachers which can be applied on students.Firstly, as religious teachers we must always be patient as was done by Prophet Muhammad when he was performing prayers and Uqbah bin Abi Muit threw waste on him where he did not get angry instead He continued His prayer. Therefore, accept the students behaviour in whatever manner they are. Secondly, teaching sincerely is very important for religious teachers in which we should not hope for any rewards, Prophet Muhammad (PBUH) said, â€Å"Verily Allah will not accept charity unless the charity is exercised in good faith and done solely to please Allah. † Even Prophet Muhammad did not hope for any material rewards when delivering knowledge.Lastly, we must emulate the forgiving character of Prophet Muhammad where He was tested by a Jewish woman who tried to poison Him and He forgave her instead of having a grudge against the her. So as religious teachers, we have to forgive our students for whatever mistakes they make to guide them to seek Allah’s pleasure and Grace. In conclusion, religious education would be pointless if the teachers themselves behave badly. Prophet Muhammad (PBUH) exemplary conduct is the one and only to emulate to help us perform our duties as religious teachers effectively in order to get Allah’s Blessings. (281 words)
