This paper explains that the antagonistic view regarding the phenomenon of Jihad is too shallow, inaccurate and unreasonable. The author explains that it is a grim fact that these views prevail as opposed to the true meaning of Jihad. Endnotes. The inception of every single religion has experienced forces working against its expansion. Consequently, there have been instances where most major religions have had to use force in order to survive, prevail or exist at all for that matter. We can look up the Christian crusades or the Samurai war crimes or the Six-day war between Israel and the Arabs or even the kamikaze pilots of the Shinto faith and the list goes on and on. Although we cannot discount the political and social undercurrents involved in these wars, anyone with little common sense can arrive at the conclusion that the core basis of these wars was religion.

History, especially from the western perspective is riddled with the Muslim conquests of Spain and India. Islam (at least in the west) has been labeled as the modern version of barbarianism. This dim sightedness is a result of several factors originating from the Muslims themselves and eventually developing into the increasingly popular concept that Islam in essence is the Mecca of le diable a quatre. If we take a closer look at the Muslim warfare, one word that comes up every time is Jihad.

buy custom Theories of Adult Development essay This gist of the following paper will discuss the life structure theory explained by a psychiatrist, Daniel Levinson. He did this piece of work together with his associates while working at Yale University Medical School. This theory tends to explain to the general public, enterprises, and social organizations that relationships are derived from an individuals life structure. Levinson had a vision of a society that focuses on fulfilling the needs of adults; with the aim of giving them an easy task to put into their roles. Their roles in turn would benefit the young population in working on the foundations of their dreams.This paper will also look at the 6 phases of adulthood according to Levinson's theory. My main reason for choosing this theory is because it comprehensively and evidently covers all stages of the human development. Levinson saw an essentiality of the growth and development of the humanity in such a manner that it would be more competent as well as more compassionate. His dream came as a result of the hard and tricky times that he had to go through in his mid-life transition to success. Levinson amalgamated a passionate, systematic interest in the entire human race with a loving inquisitiveness about nature. With his colleagues, they calculated the lives of fifty men from five diverse walks of life. The theory summarizes his findings that there exists a series of change-overs and stages of comparative constancy in the life of a male adult. Every transition assesses the preceding structure of life, and the man evaluates its relevance for the subsequent years. Transitions come into the picture during times of havoc and stress. Those times that stability strengthens someon e are those with refreshed obligation and focus. Levinson conducted series rigorous interviews with men and women in 1978 and 1987 respectively. He personally opted to do his theoretical assessment according to the stages men and women had gone through in their lifetime. The centrality of his theory is that life structures are a foundation of an individuals pattern of life at any specific time. A person's life structure is molded by his/her social as well as physical environment. An array of individuals life structures mainly revolves family and work; however, other variables like religion, race, and financial status are important as well. In his theory, there are two key concepts; the Stable Period which involves the period when someone makes critical choices in life, and the Transitional Period which is the conclusion of an individual's stage and the commencement of a new one (Levinson 1978). Life for the period of these transitions may be either unsteady or smooth, but the quality and worth of ones life obligations often transfo rm between the beginning and end of that period. Levinson's four main seasonal ccles consist of the early adult transition, early adulthood, middle adulthood, and late adulthood. In the beginning, Levinson (1978) studied 40 mature males between 35 and 45 years of age. Early adulthood comes when men bring into being their occupations and families. After an assessment of themselves at about the age of 38, men settle down and put their whole efforts toward career development. Then an additional transition happens at about the age of 40, as men recognize that certain ambitions will not be fulfilled. Throughout middle adulthood, men focus on their particular personality and put more effort for nurturing their abilities and assets. Lastly, the transition to late adulthood involves the reflection of the achievements, underperformances and failures that they celebrate the rest of life. Afterwards, in 1987 Levinson interviewed 45 women between 35 and 45 years of age. A third of them were hom emakers, another one third college instructors, businesswomen had the same proportion. Generally, he realized that women experience a similar form of cycles just as men do. Nevertheless, the life stages of women are usually closely connected with the life cycle of the family. Generally, in a deeper perspective, these periods of transition can be scrutinized to be six in number. When broken down, they include; early adult transition, between the ages of 17-22. This is when someone leaves adolescence and makes the first choices for adult life. The arrival into the adult world is between the ages of 22-28. During this time, individuals make decisions based on preliminary choices in affection, occupation, companionship, lifestyle and values. The age of 30 and beyond begins with a transition from 28-33 years of age. At this time, variations arise in the life structure; this can either be a moderate change or often a stressful predicament. The next stage is where an individual needs to relax, and Levinson branded it as Settling down. This occurs between the ages of 33-40. Here, there is an establishment of a niche in the society, advancement in a schedule, not only in family but also other career undertakings. Individuals are expected to reason and act as paren ts would do. This is the period where they face more challenging roles and anticipations. The fifth stage of life transition is the Mid-life transition between the ages of 40-45. Life structure poses as the main question, typically a period of crisis insignificance, direction, and worth of every single person's life. Ignored fragments of oneself-e.g. talents, desires, and aspirations always have the capacity to be sought and expressed. Men are perceived more as fathers and mothers than as brothers and sisters. This is in reference to other men who are to some extent younger and this message irritates them on their first encounter with it. Moreover at this period, men develop a progressively more awareness of death as they arre constantly reminded that life is short. They turn into an active participation to attempt to leave a legacy, and this commonly forms the core characteristic of the second half of their lives. The next stage is termed as entering middle adulthood which is betwe en the ages of 45-50. At this stage, choices are a necessity and a new life structure comes into the picture (Gergen 1985).An individual must pledge to new tasks. Between the ages of 50-55, termed as age of 50 transitions, Levinson noted that one could not escape a moderate transition disaster. Therefore, matters that were not fully addressed in the preceding transitions came out vehemently. The ages of 55-60 are the Second middle adult structure whereby just as the period of settling, the men have to organize themselves for the subsequent transition which is from middle adulthood and into late adulthood. Some individuals embrace this time for upgrading and realization the ages of 50. Ages of 60-65, the late adult transition, forestalls the modification in the structure from the preceding period to late adulthood. Here, changes in career are to be expected, and this would have an impact on ones self and associations. Deep reflection is associated with it and for some, this change is predominantly painful, so they attempt to avoid it. The Late adult era occurs from 65 years and above. The gentlemen must look into the sense of their earlier bein g, and begin to form the structure framed in the late adult transition. Considerably, further needs should be well-read about this period. Daniel Levinson collected this information for his studymany years ago, soon after the Great Depression. Due to this period, men came from stable families, had truthful objectives for their life and developed into adults in the growing economy. Men who have matured in the previous 4-5decades, nevertheless, have had to cope with unstable families because of extraordinary divorce rates, and their objectives are much more problematic to achieve. They have similarly to cope with a changing economy. Therefore, these modifications make it hard to relate Levinson's readings to the contemporary generation (Gergen 1991). Adult development changes with a similar change in the surroundings of an individual. Someones social class determines his/her future as well as his/his physical environment. When an individual grows, he or she develops into a new form of being. His or her attitudes, thoughts, roles, appearance, values, and capabilities change according to the age bracket he or she falls. Though the expectations are always dictated by the external forces, people still try to adjust to a niche that fit them best. Therefore, as Daniel Levinson puts it, "Adults hope that life begins at 40, but the anxiety is that it ends there." Buy custom Theories of Adult Development essay

Can a well-supported public broadcast system still offer something of Essay

Can a well-supported public broadcast system still offer something of value Can content regulations begin to disentangle the m - Essay Example Such assumptions thrive on the notion that the promotion of the government agenda forms part of the policies of the public broadcast systems. However, case analyses have shown that public broadcast systems can still achieve a high degree of proficiency in delivering value in the ways that uphold professionalism and balance. Certain universal thresholds must be met in order for the public broadcast systems to achieve the element of objectivity and trust from the multiple stakeholders. Despite favorable policies and adequate funding, public broadcast systems have to engage with certain fundamentals that relate with the establishment of principles and attitudes that attune with the core values of media and broadcasting (Crook 54). The need to protect the truth and achieve objectivity in reporting enjoins these systems to bind their practices under certain obligations that cover the interests of all stakeholders. Impartial reporting requires the adoption of a range of policies that effec tively connect with the fundamentals of business as understood under the framework of change and development. Cases abound where public broadcast systems have resisted the pressure to conform into objects of manipulation by the government. Professionalism entails the upholding of the interest of the majority while still defending the rights of the minority. Well-supported public broadcast systems in parts of the world have played important roles in criticizing negative policies (Crook 19). These systems have demonstrated a capacity to keep checks on public systems despite the fact that they draw much of their financial support from such systems. For instance, public broadcast systems in the United States have been instrumental in providing critical analyses on matters of national importance. Such matters have included policies on homeland security, approaches adopted on the global war against terrorism, government policies on spending, and other factors that involve a range of issue s that connect with matters of national importance. In these roles, the broadcast systems have faulted the government on certain flaws in its approach. Such an approach to the practice of broadcasting restores balance, objectivity, impartiality, and professionalism in the field of practice. Public broadcast systems have provided forums for parties with varying perspective without regard to affiliations or stakes. Within the aspect of professionalism, including multiple parties in the determination of processes often aligns with the need to foster understanding and inclusivity across the board. Such strategies are meant to respond to the diverse nature of the society in ways that represent the interests of all. Such an approach offers value in the practices of the public broadcast systems in the sense that they avoid the temptation of sectional appeasement and deliberate misrepresentation of issues. In order to avoid the temptations of bias and prejudicial treatment, public broadcast systems should establish the margins of influence and cooperation in ways that protect the principles of professionalism and journalistic standards as understood within a universal scope. Content regulation plays an important role in determining the performance of the media in a variety of respects. Most significantly, regulating the content of media

Judicial Process - Research Paper Example This has lead to juveniles being punished under adult criminal sentencing guidelines, which is more severe than in juvenile courts. considerable research work on juveniles in adult criminal courts have been conducted throughout time with others focusing on their character in courts, punishment outcomes in adult courts and comparing them to the juvenile courts. Juvenile Punishments in Adult Criminal Courts There have been varying conclusions into the degree of severity of the judicial outcomes, although, most concluded that the degree were less severe to those melted out to adult offenders. Juvenile courts and adult courts are very different in functionality and as such, comparison of the courts would not bring meaningful conclusions. The most practical analysis, therefore, is to look into juvenile outcomes in adult courts and compare to similar cases amongst young adults with similar offences. Several research work on this has also produced diverse results, however, most studies conc ur that juvenile status toned down the severity of sentences in adult courts, but not the actual court process. Additionally, other research work indicated that there are juvenile penalties in adult court, which seem harsher compared to similar cases by young adults. These results show several research work conducted by different scholars applying different methodologies and within different judicial jurisdiction. Sentencing Guidelines Earlier sentencing structures were consistently based on rehabilitative notions that focused on personalized punishments that would suit each offence, terms of imprisonment were varied and this allowed for a degree of flexibility in their application. Policymakers and the public however, came to realize huge loopholes in such system, this lead to proliferation of sentencing guidelines in more than half of the states. Sentencing law represents ‘procedurally rational law’ contrasting sharply with ‘substantively rational law’ th e latter provides for punishments to be personalized to fit eccentric offender needs and considerations. These presents a conflict to the society, one of establishing order and the other of punishing individuals based on unique circumstances. However, the latter applicability has always been argued aids in seeking fair just and proportional outcomes for each individual case. The guidelines that have been promulgated have lead to containment of judges’ decision, explaining the reason why judges prefer their judgment on particular cases. The sentencing guidelines also differ on jurisdiction, for instance those in the state of Maryland are different from those in the state of Pennsylvania. In recent years however, most sentencing guidelines have been more flexible in their applicability, providing a wide range of alternatives for each offence. For instance, some states implemented â€Å"presumptive† guidelines and these legally mandated judges to sentence within guideline s ranges except in rare circumstances involving departures (Johnson and Kurlychek 2012). Other states implemented less restrictive â€Å"voluntary guidelines†, which provide judges with benchmarks for sentencing, but they do not legally require the judge to sentence within the guidelines recommendations. Cases involving juveniles in adult courts by definition are atypical, this is because juvenile status represents a unique offender considerations, it may play as

International Problems in the Uk Essay This study aimed at investigating the academic writing problems of the Arab postgraduate students of the College of Business at Universiti Utara Malaysia and to provide solutions to these problems. For this purpose, four research questions were posed and the answers to these questions were provided and discussed. The data for the study were collected via (face-to-face) interviews. The informants of this study were postgraduate students from the College of Business at Universiti Utara Malaysia for the academic year 2008-2009. The findings of the study revealed that the students faced problems in relation to vocabulary register, organization of ideas, grammar, spelling, and referencing. Introduction Nowadays, English plays an important role in education and students are expected to communicate effectively in institutions where English is the medium of instruction. Learners face the task of mastering content area in subjects such as mathematics, social studies, science, and business which are taught in the target language (English). In such cases, teaching and learning of English can help the students to deal successfully with their academic demands and to perform successfully in their disciplines and professional contexts (Adams Keene, 2000). WRITING FOR ACADEMIC PURPOSES: PROBLEMS FACED BY ARAB POSTGRADUATE STUDENTS OF THE COLLEGE OF BUSINESS, UUM Fadi Maher Saleh Al-Khasawneh 1 ESP World, Issue 2 (28), Volume 9, 2010, http://www. esp-world. info In the academic context, Dudley-Evans St. John (1998) point out that the students are required to produce specific writing genres such as essay, summary, critical review, and research paper. However, focus on the distinguishing regularities of structure of different text types can help learners build a repertoire of the organization and the relevant language forms of different genres. It can also make learners aware of the socio-linguistic role that texts play in particular discourse communities. In postgraduate studies in Malaysia, as pointed out by Baskaran (1983), English plays a vital role in helping to initiate students into the academic community in acquiring not only the language proficiency necessary but the specific genres pertaining to these communities. Like any second language learners, Arab learners face many problems in acquiring English. Many studies (Abbad, 1988; Hisham, 2008; Rabab`ah, 2003; Zughoul and Taminian, 1984) have been conducted in the Arab world to investigate the problems of acquiring English among Arab learners. Zughoul and Taminian (1984: 4) found that â€Å"Jordanian EFL students commit serious lexical errors while communicating in English. † Rabab`ah (2003) emphasized that there were problems of acquiring English among Arab learners because of formal instruction by language teachers who are native speakers of Arabic. Another reason given by Rabab`ah (2003) was the limited opportunities Arab learners have to learn English through natural interaction in English since they only encounter native speakers of English who come to the Arab world as tourists. Hisham (2008) investigated the problems that Arab students of business might have at University WRITING FOR ACADEMIC PURPOSES: PROBLEMS FACED BY ARAB POSTGRADUATE STUDENTS OF THE COLLEGE OF BUSINESS, UUM Fadi Maher Saleh Al-Khasawneh 2 ESP World, Issue 2 (28), Volume 9, 2010, http://www. esp-world. info Utara Malaysia. He found that those students face problems in vocabulary register, grammar, and referencing. Abbad (1988: 15) admits the weakness of Yemeni learners of English, and he states that â€Å"in spite of the low proficiency level in English of most applicants (Yemeni learners), they are accepted into the English department. † In most of the Arab universities, high school graduates are still accepted to pursue a program, such as English Studies, in spite of their weaknesses in that language. Arab learners find it difficult to communicate freely in English. Abbad (1988) mentions that their problems are due to the inappropriate methods of language teaching and the learning environment which some judge are unsuitable for learning a foreign language. The students appeared to have many problems when writing in English, like not knowing how to organize their ideas, because it is a new experience for them. For students to succeed in a foreign language generally, and writing skills specifically, they need to surround themselves in a language learning environment. In the case of the Arab world, Arab learners have little opportunities to use the foreign language in their society. As a result, many problems occur when they study at a university where the medium of instruction is a foreign language like English. Literature Review English for Specific Purposes (ESP) is divided into English for Occupational Purposes (EOP) and English for Academic Purposes (EAP). It aims to prepare students, in a relatively short period of time, to communicate, read, and write better so they can work WRITING FOR ACADEMIC PURPOSES: PROBLEMS FACED BY ARAB POSTGRADUATE STUDENTS OF THE COLLEGE OF BUSINESS, UUM Fadi Maher Saleh Al-Khasawneh 3 ESP World, Issue 2 (28), Volume 9, 2010, http://www. esp-world. info appropriately and successfully in certain activities. In order to achieve this goal, ESP activities have to be presented in context because context is the central idea of ESP. The other point that has to be taken into consideration in teaching ESP is to use authentic materials; this will lead the students to acquire what they need to develop for their jobs (Hutchinson Waters 1987). According to Dudley-Evans (2001), the absolute characteristics of ESP are: †¢ †¢ ESP is designed to meet the specific needs of the learners. ESP makes use of the underlying methodology and activities of the specialization it serves. †¢ It is centered not only on the language (grammar, lexis, register), but also on the skills, discourses and genres appropriate to those activities. English for Occupational Purposes (EOP) EOP can be grouped into business English, professional English (e. g. English for doctors, lawyers) and vocational English (e. g. English for tourism, aviation, and nursing). Several studies (Flanegin and Rudd, 2000; Goffman, 1979; Pakir, 1999, Puvenesvary, 2003) have been conducted on the importance of English in the occupational fields. Flanegin and Rudd (2000) discuss the need and importance of English skills in all professions. In addition, they emphasize on the importance of communication skills in the business and management fields by suggesting some solutions to enable students to be good communicators in business majors. Goffman (1979) indicates that business negotiations are carried out and letters are usually written in English. This sometimes discomforts those whose first language is not English.

In fact, Pakir (1999) points out that the spread of English is most likely to continue because of the rapid spread of telecommunication, mass communication, business, and internet links. Thousands of international non-native to non-native communication and deals are undertaken daily in a huge number of settings: trade, diplomacy, tourism, journalism, science and technology, politics etc. As a result, there is a need to ensure there are competent writers and speakers of English. Puvenesvary (2003) reveals the importance of being a competent writer of English in the banking sector in Malaysia and the consequences of poorly-written business letters to clients. Methodologies for Teaching Writing for Academic Purposes Prior to discussing the theories related to writing for academic purposes, a few studies will be highlighted in relation to writing problems (Arndt, 1987; Badger and White, 2000; Davies, 1988; Hyland, 2003; Jordan, 1997; Kambal, 1980; Myles, 2002; Paltridge, 2001; Silva, 1990; Smith, 1982; Swale, 1990; Tribble, 1996; Vygotsky, 1978; and Zughoul and Husain, 1985). Kambal (1980) analyzed errors in three types of free composition written by first year Sudanese university students. The study took into consideration the major syntactic errors made by these students in the verb phrase and the noun phrase. Also, Kambal (1980) reported that the three main types of errors made in the verb phrase are verb formation, tense, and subject-verb agreement. He discussed errors in tense within five categories: tense sequence, tense substitution, tense marker, deletion, and confusion of perfect tenses. WRITING FOR ACADEMIC PURPOSES: PROBLEMS FACED BY ARAB POSTGRADUATE STUDENTS OF THE COLLEGE OF BUSINESS, UUM Fadi Maher Saleh Al-Khasawneh 5 ESP World, Issue 2 (28), Volume 9, 2010, http://www. esp-world. info The findings of this study reveal that the third-person singular marker was used redundantly, and they also revealed the use of the incorrect form of verb to be. Zughoul and Husain (1985) point out that the lack of lexical variety, subordination, and their heavy reliance on redundancy that does not add any new information to the text are the main problems learners have in writing skills. As a result, L2 practitioners are still in search of a coherent, comprehensive theory of the teaching of writing. The major writing theories proposed in the literature are product, process, and genre. Product Approach According to Silva (1990), the product theory of writing highlights form and syntax and it emphasizes rhetorical drills. The product theory focuses on the written product rather than on how the learner should approach the process of writing. In this theory, writing concerns the knowledge about the structure of language, and writing development is the result of the imitation of input (Badger and White, 2000). In addition, Arndt (1987) argues that the importance of imitation and a model in this theory are not only for imitation but also for exploration of analysis. Similarly Myles (2002) confirms that if the students are not exposed to written model texts, their errors in writing are more likely to subsist. In fact, Jordan (1997) indicates that the students are required to focus on a model, form, and duplication. In other words, the students study model texts and attempt various exercises that enable them to draw attention to relevant features of a text, and then replicate them in their own writing. WRITING FOR ACADEMIC PURPOSES: PROBLEMS FACED BY ARAB POSTGRADUATE STUDENTS OF THE COLLEGE OF BUSINESS, UUM Fadi Maher Saleh Al-Khasawneh 6 ESP World, Issue 2 (28), Volume 9, 2010, http://www. esp-world. info Process Approach Another theory which was proposed in order to teach writing is the process theory. Hyland (2003) indicates that the process theory focuses on how a text is written instead of the final outcome. He adds, the process theory has a major influence on understanding the nature of writing and the way writing is taught. Therefore, the process theory emphasizes on the importance of certain procedures such as pre-writing, drafting, evaluating, and revising. He pointed out that the process theory would involve introducing techniques that help the students identify and engage a topic; students are required to show multiple drafts of a work. After discussion and feedback from evaluators, the students would revise the drafts. Rewriting, revision, and editing are essential parts to writing in this theory. In a similar vein, Jordan (1997) states that process writing enables the students to make clearer decisions about the direction of their writing by certain procedures such as discussion, tasks, drafting, feedback, and informed choices. The advantage in adopting the process theory is in updating the importance of the cyclical and recursive nature of writing that is employed by native writers where ‘ordinarily pre-writing, writing, and rewriting frequently seem to be going on simultaneously’ (Smith, 1982: 104). Tribble (1996) explains the process-based approach in teaching academic writing. He says that the students first brainstorm in small groups the topic to be discussed in writing; this helps them to generate ideas before starting to write. This is followed by gathering an outline of the essay and individually writing its first draft. Students revise their first drafts WRITING FOR ACADEMIC PURPOSES: PROBLEMS FACED BY ARAB POSTGRADUATE STUDENTS OF THE COLLEGE OF BUSINESS, UUM Fadi Maher Saleh Al-Khasawneh 7 ESP World, Issue 2 (28), Volume 9, 2010. http://www. esp-world.info and give them to other students for peer-reviewing and commenting on. The final stage is editing the essay by the writer himself/herself to eliminate all language errors. Thus, this approach focuses on process rather than product. Genre Approach The genre theory in writing emphasizes on the social context in which writing is produced (Badger and White, 2000). Swales (1990) explains that the genre theory is a class of communicative events and that the members of the communicative events share some set of communicative purposes which are identified by the expert members. In the academic context, the experts will be the lecturers who are teaching the various subjects. As claimed by Davies (1988), students, teachers, and subject tutors are all involved in the written language for a selected field of study and the forms of expression permitted within the field. Davies (1988: 131) suggests that the students, in aiming to attain academic success ‘somehow discover the criteria by which the different genres they produce are assessed. ’ He seems to suggest that the criteria are not made explicit to students. Swales (1990) emphasizes the genre-based approach in teaching academic writing. He focuses on analyzing communicative purposes of the text read by learners and the means used by the writers of these texts to reach such purposes. In this approach, the students learn to write their own texts trying to achieve similar communicative purposes by way of choosing the most suitable and expressive language means for that.

Thus, the aim of the genre approach in writing is to help students master the conventions of a particular form of genre that is relevant to their specific situation. This approach requires collaboration with instructors from the disciplines, which may not always be possible (Flowerdew, 2002). It is important for the teachers to have cooperation with the students, with the teacher taking an authoritative role to support learners as they move towards their potential level of performance. Similarly, Paltridge (2001) proposes a framework that involves exploring the texts and contexts of students-target situation, enabling reflection on writing practices, exploiting texts from various types of genre and creating mixed genre portfolios.

Research Design This study is a qualitative study and it utilized semi-structured interviews in a face-toface interaction to explore the students’ beliefs and thoughts about certain topics, this is in line with Lynch’s (1996) view that, the use of semi-structured interviews enhances the understanding of the data and makes the data collection more systematic as compared to the informal conversational approach. Findings and Discussion The findings reported in the next section are based on the four questions posed in the students’ interviews. Writing Types in the Business Programs. It was found that the business students interviewed were required to write several types of academic texts: project papers, article reviews, summaries, reports, article critiques, proposals, comparative analyses, book reviews, essays, and case studies (see table 1).

This is because these’ tasks require students to employ their critical thinking skills, read widely, and apply what they have learnt in their courses. This list of tasks provided partially concurs with the findings of Barbara et al. (1996) who pointed out that reports, WRITING FOR ACADEMIC PURPOSES: PROBLEMS FACED BY ARAB POSTGRADUATE STUDENTS OF THE COLLEGE OF BUSINESS, UUM Fadi Maher Saleh Al-Khasawneh 12 ESP World, Issue 2 (28), Volume 9, 2010, http://www. esp-world. info proposals, and projects are the most frequently written business tasks performed by business students. The identified tasks can provide English language instructors insights into selecting and implementing tasks for the English for Business courses. Teachers and curriculum developers can create business English courses based on the results of the needs analysis carried out in the study. Thus, teachers and curriculum developers can give special attention to tasks like projects and reports in the language courses, so that students can be well versed in these tasks. This is in line with the view of St. John (1996) and Chew (2005) who claimed that frequent target tasks can offer a tentative foundation for choosing and implementing tasks for the targeted Business English Communication course. Problems with the Writing Tasks It was found that while carrying out their writing tasks, the business students face problems in vocabulary, grammar, organization of ideas, spelling, and referencing (see table 2).

As shown in this study, the postgraduate students of the COB programs at UUM have problems in English academic writing. The major problem that the students mentioned is vocabulary. This is because a reasonable vocabulary size is needed for students to function effectively in their programs. This concurs with Coxhead Nation (2001) who stated that approximately 2,000 words are seen in most uses of the English language. The standard list of these words is the General Service List (GSL) of English Words. The GSL is divided into two parts, the first one is GS1 which contains 1,000 words and the second part is GS2 which also contains 1,000 words. GS1 covers about 77% of academic texts and GS2 25%. The first category contains words that frequently appear in academic texts regardless of subject areas, but they are not common in non-academic materials. As WRITING FOR ACADEMIC PURPOSES: PROBLEMS FACED BY ARAB POSTGRADUATE STUDENTS OF THE COLLEGE OF BUSINESS, UUM Fadi Maher Saleh Al-Khasawneh 14 ESP World, Issue 2 (28), Volume 9, 2010, http://www. esp-world. info a result, learners have to learn the words in the GS2 so that they would have less difficulty in pursuing their postgraduate studies. In addition, Rabab`ah (2003) pointed out that the students often lack the necessary vocabulary when they are engaged in authentic communicative situations such as writing and speaking. As a result, the students will be unable to express their ideas freely and accurately because of their limited vocabulary. These difficulties can be solved by offering more discipline-specific reading courses in order to improve the students’ vocabulary size and depth to help them in their academic writing. Also, the students become aware of what to expect in their academic disciplines. This is in line with Kasper’s (2000) view that by providing materials that concentrate on content, the students can be aware of the concepts, audience, and the purpose of their academic disciplines. Moreover, the findings of the current study revealed that the students face difficulties in grammar. Grammar is extremely important in conveying accurate messages. Key grammatical forms include tenses, voices, modals, articles, nominalization, and logical connectors (Dudley-Evans St. John, 1998). Therefore, it is advisable to restrict these forms and create materials which enable the students to progress in their academic writing. This coincides with Hutchinson Waters (1987), who emphasized on identifying the grammatical forms and produced materials that took these forms as their syllabus. Allen Widdowson (1974) stated that the students’ needs could be only met by WRITING FOR ACADEMIC PURPOSES: PROBLEMS FACED BY ARAB POSTGRADUATE STUDENTS OF THE COLLEGE OF BUSINESS, UUM Fadi Maher Saleh Al-Khasawneh 15 ESP World, Issue 2 (28), Volume 9, 2010, http://www. esp-world. info a course that develops the knowledge of how sentences are combined together to make meanings. Another problem, which has been mentioned, was the problem of referencing. Writing references according to certain conventions (APA, IEEE, etc) helps the students to be scholarly writers and trains them in academic integrity. Using certain computer programs such as the End-Note program could help the students to achieve that purpose. As such, COB should conduct training sessions for students to use that kind of program which is available in the UUM library. Causes of Writing Problems It was found that the students attributed their problems in English to their weak foundation, environment, and methods of teaching English in their countries. Weak foundation is related to the status of English, the students’ motivation to learn English, and the teachers’ lack of interest. Environmental reasons include the use of the mother tongue, few opportunities to practice English, and isolated culture. On the other hand, methods of teaching English included the medium of instruction, using Arabic in English classes, writing done in Arabic, teachers’ low proficiency in English, and lack of writing practice in educational institutions (see Table 3).

Most of them emphasized the role of COB, others emphasized the learners’ roles, and some concentrated on the teachers’ roles, and the writing development process (see table 4. 4).

They suggested that teachers ought to correct the students’ grammatical errors. This coincides with Gocsik (1997) who argued that dealing with the students’ grammatical errors, as they arise in students’ writing is helpful. By doing so, it helps to build students’ awareness of the different types of grammatical errors they are making and encourage them to check their errors by using grammar handbooks. Moreover, the students proposed that teachers should employ multiple teaching techniques in order to improve students’ academic writing. Using some fun activities like games and scrambled sentences would motivate the students’ in learning English. This concurs with Ober (1992) who emphasized on including micro-writing activities that focus on the students’ problems in writing and using activities that are simple and related to the students’ academic disciplines. The students also proposed that lecturers should increase the number of writing tasks. They believe that by doing so, they would strengthen their abilities in academic writing. In this way the students will be required to write some of the academic writing tasks, if these tasks were attached with the lectures’ feedback. The students will be aware of their errors and will try to improve their academic writing after knowing their weak points. This is in line with Russell (1991) who suggested including more writing in disciplinespecific courses because each discipline has its own terminologies of language use and style that can best be taught to students in the specific contexts of courses in the disciplines. WRITING FOR ACADEMIC PURPOSES: PROBLEMS FACED BY ARAB POSTGRADUATE STUDENTS OF THE COLLEGE OF BUSINESS, UUM Fadi Maher Saleh Al-Khasawneh. 19 ESP World, Issue 2 (28), Volume 9, 2010, http://www. esp-world. info The students were aware that by providing discipline- specific English materials, they can develop their writing abilities. So, it is advisable for the college to initiate disciplinespecific English classes where materials contain discipline specific register. It is recommended that the students take intensive English courses which are related to their academic disciplines. This is to help familiarize students with the writing demands of their disciplines. This is in line with Jordan (1997) who indicated that the students are required to focus on their academic genres and duplication. In other words, the students study genre texts and attempt various exercises that enable them to draw attention to relevant features of a text, and then replicate them in their own writing. Conclusion For the purpose of exploring the problems that Arab postgraduate students at COB might face, an investigation was carried out on the writing tasks that are carried out and the causes of these problems, and suggestions to overcome these problems were provided. Semi-structured interviews were used to collect the data. The findings of the current study may help the curriculum developers to improve the current curriculum of COB and design Business English courses that could meet learners’ needs and wants. This coincides with Dudley-Evans (2001) who views ESP as a means to meet the specific needs of the learners. The ESP practitioners can utilize the findings of the study to design ESP courses which deals with the academic writing process.

History of Vampirism :: Vampire Vampires

"Forgotten through the fabric of space and time are the children of the night" Anonymous. Although the mere sound of vampirism, when uttered in the drenches of the darkest corners of the human soul can spark tepidity and obscurities as to its origins accompanied by the mystifying attraction that compels individuals to adhere to the often times fallacious discernments which the terminology conveys, it is a matter of personal introspection which enables one to really grasp the epistomological aspect of vampirism. Historically, beliefs in vampirism has existed throughout the primordial period, and the superstition behind it was only intensified during the rule of Vlad Dracula. Apparently, it was Vlad the impaler who had anthromorphosized vampirism into the black, blood-lusting seductor as it is portrayed today. Blood is the quin-essential molecule predominantly necessary as the pervious substance that upon transfer from on individual to another possesses the ability to either take life or give life. This is very important symbolistically due to the inherent nature of the substance. Nowadays, with the advent of modern technological advances blood can be defined scientifically as an interstitial fluid that's characteristic of a connective tissue which contained glycoproteins, lipoproteins, oligosaccharides, and conceivably other chains of carbohydrates which are essential to the transport of nutrients and oxygen to and fro --- in order to supply our cells and tissues with adequate amount of nutrition for metabolic and life-sustaining or life-proliferating processes. With the latter known information, it's more than enough detail that can last a lifetime for those individuals interested in becoming hematologists. So to return to the vampiristic misconceptions that society seems to stigmatize with the living undead "nosferatu" bloodsuckers whatever vocabularistic description one seems fit to coin in association with these mythologic creatures. It seems that there's an equivocal understanding of these creatures from the darkness of our hearts. First misconception is to assume that threre exist a race of creatures or subterranean humans known as vampires. To denounce this premise lets suppose that they really do exist. Well if the latter premise is true, and since these creatures are nascent since the beginning of the creation of the earth, then why hasn't there been irrefutable evidence upon the capture and attainment of one of these supposedly thriving creature? It would seem that the only plausible conclusion is that there is no evidence that hints on the existence of such a race of creatures(or heterogenic-humans).

Speaking Through the Movement of Dance.

Speaking Through the Movement of Dance Summary: Many people think of dance as human communication at its most basic level. Some form of dance can be found in every culture, regardless of its location or stage of development. It is easy to see that dance is a natural, universal human activity. But what most people overlook to see is that dance can be found as a form of writing just like any other genre out there. So this explains how and why dance is a form of writing, and goes specially into choreographed dancing and how routines are a part of writing. What’s the first thing that pops in your head when you think about dance or dancing?That its form of writing right? WRONG! When thinking about dance or dancing the first thing most people think about is shaking their butts across the dance floor while grooving to the latest jams. But what most people don’t realize is that dance is a form of writing, weird right? I would of never guessed that either, until I went on a rece nt trip back to Chicago, and one of my best friends invited me to a dance performance at her school, not only was the show very entertaining. I learned that dance is more than moving to the rhythm of the beat to your favorite song, but that dance tells a story.Which most people don’t realize. Dance routines are very unique and explore states of mind and feelings such as pleasure and pain. I’ve heard people who like to dance mention things like dancing is form art and writing. They say some people dance to express their feelings and emotions. Other people dance to feel better, but dance can be used to tell a story. As if it is a language or written in a book. It utilizes many of the elements that can be found in other forms of writing and genres like tattooing’, graffiti, Facebook post and many more.But what is dance really? You +1'd this publicly. UndoDance is when people move to a musical rhythm. They may be alone, or in a group. The dance may be an informal pl ay, part of a ritual, or part of a professional performance. There are many kinds of dance, and every human society has its dances. Dances may be planned in detail, or they may be whatever dancers feel like doing. However, most dancing does follow some general style or pattern. Dance takes as its subject matter moving visual patterns, feelings, states of mind, and narrative, in various combinations.The form of the dance, the details and the parts as they work together to organize the structure, gives us insight into the subject matter. However, the details, the parts, and the structure are not as easily perceived as they are in painting, sculpture, or writing. Because when in dance you have to pay very close attention to the little details and follow and feel what the dancers are doing. In this article I want to take a closer look only on choreographed dancing and how it’s a form of writing because the word choreography literally means â€Å"dance-writing†. Choreograph y is not just stringing together steps and figures.That's boring. When choreographing a dance you need to first ask yourself why the audience is there. What do they want to see? What would interest them? Why should they like your piece? Or even if they don't like it, how will it impact them. What will hold their attention at each moment? Keep your audience in mind during every step of your design. Just like an author when writing a book or any writing you still need to follow the same kind of steps in order for people to recognize and acknowledge your work because no one wants to read a boring book nor want to see a boring dance. hat’s why practice makes perfect. Writing, obviously, is my favorite form of expression. It allows me to dance with words, spin with anecdotes and tap out my frustrations. Just like dancing, it is not always easy or a graceful performance. Sometimes I falter, fall, miss a step and tap off beat. I sweat a lot when I’m on deadline and I doubt my abilities when the task is difficult. But at other times, my words gracefully fly off the page like a ballerina mastering a leap. When I keep trying and practicing, the steps get easier and encourage me to keep dancing along.I can also express myself as a writer, expanding my repertoire with different styles. Just as dancers switch from tap and ballet to hip hop and jazz, writers also strengthen their skills and express themselves by varying the tone, organization and style. When I’m frustrated, I tap out an opinion piece to persuade my audience. When I’m happy, I compile a light-hearted narrative or anecdotal piece. When I’m feeling sassy, I throw a little attitude into a blog post and quite often, I spruce up my wording to jazz up an article. In reality, writers are dancers at heart.We sway to the words, we feel the meaning we wish to express and we type to a rhythm with every piece. And sometimes, we pop, lock and drop it just for fun.

Shop Organization [pic] BLACK SMITH AND HEAT TREATMENT INTRODUCTION Smithing is understood to handle relative small jobs only such as can be heated in an open fire or hearth. The shop in which the work is carried out is known as smithy’s or smithy shop and various operation are performed by means of hand hammer or small power hammers.Forging refers to production of those parts which must be heated in a close furnace. The portion of work in which forging is done is termed as the forge and work is mainly performed by means of heavy hammers, forging machines and presses. Shaping of metal is done either by steady comp ression or by impact between hammer and anvil after heating it above recrystallisation temperature in forging. Forging can be defined as the controlled plastic deformation of metal at elevated temperature in to a predetermined sizes and shapes using compressive forces exerted through some type of die by a hammer, a press or an upsetting machine.The B. S. H. T. shop is divided as:- 1. Draw gear section 2. Buffer section 3. Spring section INSTALLATIONS 1. Pneumatic power hammers (5 nos. ) 250 kg. Capacity-2nos. 500 kg. Capacity-1nos. 1000 kg. Capacity-2nos. 2. Hydraulic presses (3 nos) 3. Combined shearing, punching and nibbing machine (1 nos) 4. Spring testing machine (2 nos. ) 5. Air blowers (2 nos. ) 50 h. p. 6. Grinder (1 nos. ) 7. Circular saw (1 nos) 8. Power hacksaw (1 nos ) 9. Furnace (6 nos) 10. Shot peening machine (1 nos) 11. Tension (proof load ) testing machine (1 nos) PNEUMATIC POWER HAMMER:-The hammer has two cylinders compressor cylinder & ram cylinder. Piston of compr essor cylinder compresses air and delivers it to the ram cylinder where it accelerate the piston, which is integral with ram delivering the blows to the work. The reciprocation of the compression piston is obtained from a crank drive which is powered from a motor through reducing gear. The air distributor device between the two cylinders consist of rotary valves with parts through which air passes into the ram cylinder, blows & above the piston, alternatively. This drives the ram up & down respectively. HYDRAULIC POWER PRESS:-In power press the ram is driven by power instead of hand as in the case of hand press , The principal of a typical forging press is as follows:- The fluid passes first from a large capacity tank to a pump and then is delivered on the press with the aid of an accumulator and distributor at a pressure of at a pressure of at 200 to 300 kg/cm. The accumulator fluid pressure flows into to main cylinder and pressure on the top of the large piston. Since the cross-se ction area of the piston in the main cylinder is large, the press ram is forced down upon the material to be forged which lies on the anvil with high total power.Each power stroke the large piston is returned into its initial position by action of the working fluid on the piston rod in the pull back cylinder. To perform this motion, a relatively lower fluid pressure, but a large volume of water per unit time is required to accelerate the return stroke. FURNACES: The job is heated to correct forging temperature in a hearth or furnaces. The gas and oil are economical, easily controlled and most widely used fuels. In workshop, we used coal and crude oil as fuel forge furnaces are built so as to ensure a temperature up to 1350 degree centigrade in their working chamber.Two types of furnaces are used in this shop:- 1. Coke fired furnaces 2. Coal fired furnaces In cock furnace coke is used as fuel. In oil fired furnaces diesel is used as fuel. Diesel is sent by cast iron pipes from diesel tank in an injector and compressed air is sent on high intensity by a blower. The air jet mixed with diesel is used as fuel in oil fired furnace. Furnace are used to red hot the raw material to the required temperature. Fuel is injected into these furnace with a great pressure associated with air blast. This high pressure is generated by centrifugal air compressor, which is situated in the shop itself.This compressed air from the compressor is then taken to several furnaces through the underground pipes. One man is present near the furnace that puts the raw material and takes out the red-hot material, which is then placed under power hammer. After acquiring the required shape, these products are either hardened by various hardening procedures or simply cooled to the atmospheric temperature. Draw Gear Section:- The draw gear and screw coupling are used to connect two coaches to each other. These are designed for a proof load of 75tones and breaking load of 130t.The components are sp ecially heat treated to achieve the load bearing capacity. In maintenance procedure of draw gear and screw coupling stress relieving is done. The components made of st 60-61 are to be stress relived and the new material introduced for draw gear IS: 5517-93 Grade35Mn6M03 is not to be heat treated. The maximum temperature up to which draw gear can be heated is 550 C. Buffer Section:- Buffers are used to absorb the shock during impact action of coaches. Apart from absorb the impact energy it also guide the coaches to align in track during turn on curvature.Each buffer has capacity of 1030 kg-m with a total stroke of 127 mm. Rubber springs are used in this buffer assembly so it have low absorption capacity in earlier part of the stroke which rises rapidly towards the end resulting in absorption of high shock loads and transmitting of minimum end pressure to under frame. Components of buffer assembly: ? Buffer casing (cast steel) ? Buffer plunger (cast steel, forged) ? Rubber buffer pads ? Buffer spindle ? Destruction tube ? Recoil spring ? Recoil spring parting plate ? Buffing spring parting plate ? Recoil spring washer ? Face plate for buffer plunger M-24 Hex head bolt Spring Section:- The springs are used in the bogie for the suspension system of coaches. There are two types of suspension as primary and secondary suspension. The springs classified to primary and secondary system by the load carried by them. Fig: Inspection procedure:- Inspect all components visually for dimensional distortion and surface defects such as cracks, wear, dent marks and pitting etc. Remove scale, rust, light cracks by grinder. Stress relieving. In case of doubt of cracks dye penetration or magna flux machine is used to check the cracksLoad test is done on load testing machine for 100t to 150t. In all this procedure if component is find ok then it is dispatched to the assembly. ROLLER BEARING In passenger coaches of Indian Railway system, only single bearing type axle box arrangement is used, means only two bearing are used to support the axle. The bearing used for this purpose is of Spherical Type Roller Bearing. CONSTRUCTION:- Spherical roller bearing consist of an outer ring having a spherical race way within which two rows of barrel shaped rollers operate. These rollers are guided by an inner ring with two raceway separated by a center rib.This bearing has self alignment. Spherical roller bearings have a large capacity for radial loads, axle loads in either direction. Spherical roller bearing no. 22336/c3 with 130 mm parallel bore on the inner ring are being used on ICF type coaches. They are directly shrunk fit on the axle journals. These roller bearings are to be inspected periodically as per schedule. Fig: TOOLS AND PLANTS FOR MAINTENANCE OF ROLLER BEARING:- |S. no. |Function |Equipment used | |1. Cleaning of roller bearing |3 stage cleaning plant or pre wash, wash & water rinsing | |2. |Dismounting of spherical roller bearings |Hydraulic dismounting equ ipment-withdrawal nut | |3. |Mounting of roller bearings |Induction heater with demagnetizing device | |4. |Securing of end locking bolts |Torque wrench | |5. |Visual inspection of demounted roller bearings |Magnifying glass with light | |6. Checking of radial clearance |Long feeler gauge | |7. |Measurement of journal |Outside micrometer | | | | | | | | | DISMOUNTING OF BEARING:- ? For dismounting of bearings, special hydraulic dismounting equipment is used.This machine injects oil between the journal and bore to the inner ring with high pressure which expands inner ring resulting in breaking of interference. The bearing becomes loose on the journal and slides over it. The bearing is then removed from the journal and sent to the cleaning plant. ? All components of bearing such as inner ring, outer ring, rollers, and cage are examined for cracks, damage and breakage. If bearing is found free from all the defects mentioned above, the radial clearance is measured with feeler gauge. R adial clearance is not within prescribed limits, the bearing is rejected.RECOMMENDED RADIAL CLEARANCE LIMITS FOR BEARING IN DISMOUNTED CONDITION: |Bearing make |Radial clearance | |SKF |0. 105 to 0. 296 mm | |NBC |0. 080 to 0. 190 mm | MOUNTING OF BEARING:- ? Before mounting the bearings, it is checked that journal and shoulder diameters are within permissible limits. All direct mounted spherical roller bearing have interference fit with axle journal, therefore it requires heating and shrinkage fitting. Heating of bearings is done by using an induction heater. Fig: ? Temperature range for heating the bearing is 100 to 120 centigrade. ? Induction heating is a quick, safe, energy saving and environment friendly process. In this system, bearing is short circuited to perform as a secondary winding whereas the core winding is at primary side. Bearing is placed around a yoke. Due to principal of induction current, bearing is heated due to its electrical resistance and attains the desired temperature. It is recommended to set the machine in such a way that it takes 5 to 7 minutes to attain the temperature of 120c maximum of bearing. ? Heated bearing mounted on journal with the help of hook and it is positioned by giving light taps with plastic hammer. BEARING IS REJECTED FOR THE FOLLOWING DEFECTS: ? Pitted or flaked roller tracks and rollers. ? Cracked or deformed or badly worn out cage ? Cracked inner or outer ring ? Scored or damaged outer surface of the outer ring. ? Indentation or rings or rollers ? Scoring of roller tracks or rollers ? Corrosion damage Excessive or less radial clearance CORROSION SHOP ICF coaches incorporate a no. of pressed steel sections made of thin sheets (1. 6, 2. 0, 2. 5, & 4 mm) and plates of thickness 5 to 16 mm in the construction of the shell. These sheets are considerably stressed as the design of the coaches is based on the principle of a self supporting structure and it is essential that these coaches are maintained in good conditi on free from corrosion. Corrosion is take place when a steel surface comes in contact with moisture. For prevention the corrosion, film of paint is coated on steel surfaces.In addition to it, application of an inhibite Zinc Chromate Red Oxide Primer is done to prevent the surfaces coming in contact with atmosphere. Surfaces which are not finish painted have also been given ? coats of bituminous emulsion which gives added protection to the steel surfaces by excluding moisture along with primer. If due to some reason like abrasive action of sand, the bituminous film brake down, the inhibitive primer acts as a second line of defence. Corrosion of steel surfaces starts only when both the bituminous and the primer suffer mechanical injury.Corrosion is indicated by: ? Flaking of paints ? Flaking of metals ? Pitting and rusting Corrosion can be classified into two categories as vulnerable and not vulnerable. Vulnerable corrosion of parts means, the parts are fully corroded and they should be changed for further operation. The examples of vulnerable members in coaches are tubular frame below lavoratories, trough floor in bays, sole bar, body pillars etc. Not vulnerable parts mean the parts which are corroded to little depth and they may be use still by treatment of corrosion.The examples of mot vulnerable members are head stock inner and outer along with stiffening tubes, roof sheets, body side doors, partition walls, water tank ceiling construction, battery box etc. All the components of coaches are examined in following way for corrosion:- ? Visual inspection ? By spiked hammer ? In the inner surfaces by making g the holes in corresponding component. ? If the components are corroded excess as prescribed limit then change the component by new one. ? And if the component is not so much corroded then repair the component by scrapping old coats of paint and make new coats of paints of anticorrosive layerBRAKE GEAR SHOP Presently coaches are mounted with air brake system instead of vacuum brake system due to better braking application. The air brake used is TWIN PIPE GRADUATED RELEASE AIR BRAKE SUSTEM. In this system two pipes known as feed pipe and brake pipe are used, instead of that there are two brake cylinder on each bogie, one auxiliary reservoir, a distribution valve, a control reservoir etc. The air brake system uses compressed air supplied by the main reservoir in locomotive. The locomotive compressors charge the feed pipe throughout the length of the train .The feed pipe is connected to the auxiliary reservoir and the brake pipe is connected to the brake cylinder through the distributor valve. Brake application takes place by dropping the pressure in the brake pipe. Charging the brake system †¢ Brake pipe throughout the length of train is charged with compressed air at 5 kg/cm2 †¢ Feed Pipe throughout the length of train is charged with compressed air at 6 kg/cm2 †¢ Control reservoir is charged to 5 kg/cm2 †¢ Auxiliary reservoir is charged to 6 kg/cm2 Brake application stage For brake application the brake pipe pressure is dropped by ventilating air from the driver’s brake valve.Subsequently the following actions take place †¢ The control reservoir is disconnected from the brake pipe. †¢ The distributor valve connects the auxiliary reservoir to the brake cylinder and the brake cylinder piston is pushed outwards for applications of brakes. †¢ The auxiliary reservoir is however continuously from feed pipe at 6kg/cm2 |Description |Reduction in B. P Pressure | |Minimum Brake application |0. 5 to 0. kg/cm2 | |Service Brake application |0. 8 to 1. 0 kg/cm2 | |Full service Brake application |1. 0 to 1. 5 kg/cm2 | |Emergency Brake application |Brake pipe is fully exhausted and its pressure reduces | | |to almost zero. | Brake release stage: Brakes are released by recharging brake pipe to 5 kg/cm2 pressure through the driver’s brake valve. ? The distributor valve isolated the brake cylinder from the auxiliary reservoirs. ? The brake cylinder pressure is vented to atmosphere through DV and brake cylinder moves inwards. [pic] BRAKE CYLINDER Every coach fitted with air brake system, have two brake cylinders for actuating brake rigging for the application and release of brakes. During application of brakes the brake cylinder develops mechanical brake power by outward movements of its piston assembly, by receiving air pressure from auxiliary reservoir through the distributor valve.This mechanical power is transmitted to the brake shoes through a combination of levers. During release action of brakes the compression spring provided in the brake cylinder brings back the rigging to its original position. The cylinder body is made out of sheet or cast iron and carries the mounting bracket, air inlet connection rib and flanges to the cylinder body a dome cover is fitted with the help of bolts and nuts. The dome cover enclosed the spring and passage for the piston trunk which is connected to the piston by screws.The piston is cast iron having a groove in which piston packing is seated . piston packing is of oil and abrasion resistant rubber material and is snap fit to the piston head. The packing as self lubricating characteristic which ensure adequate lubrication over a long service period and extends seal life considerably. AUXILARY RESERVOIR The auxiliary reservoir is a cylindrical vessel made of sheet metal. On both the ends of the reservoir, flanges are provided for pipe connections. One end of the auxiliary reservoir is charged through the feed pipe to a pressure of 6 kg/cm2 .At the bottom of the auxiliary reservoir, a drain cock is provided for draining out the condensate/moisture . The auxiliary reservoir should be overhauled in every POH. DISTRIBUTOR VALVE Distributor valve is the most important functional component of air brake system and is also referred as the heart of air brake system. The distributor valve sense drop and rise i n brake pipe pressure for brake application and release capacity. It is connected to the brake pipe through branch pipe.Various other components connected to the distributor valve are auxiliary reserve reservoir, brake cylinders and control reservoir. FUNCTION OF DISTRIBUTOR VALVE For application and release of brakes the brake pipe pressure has to be reduced and increased respectively with the help of driver’s brake vale. During these operations the distributor valve mainly performs the following function. i) Charges the brake system to regime pressure during normal running condition. ii) Help in graduated brake application, when pressure in brake pipe is reduced in steps. ii) Helps in graduated brake release, when pressure in brake pipe is increased in steps. iv) Quickly propagates reduction of pressure in brake pipe throughout the length of the train by arranging additional air pressure reduction locally inside the distributor valve. v) Limits maximum brake cylinder pressu re for full service applicationemergency application. vi) Control the time for brake application and brake release depending on service conditions. vii) Facilitates complete discharge of air from the air brake system manually with the help of operating lever. iii) Protects overcharging of control reservoir when the brake pipe pressure is quickly increased for releasing the brakes. C3W DISTRIBUTOR VALVE The C3W distributor valve consists of: 1) Main body 2) Quick service valve 3) Main valve 4) Limiting device 5) Double release valve 6) Auxiliary reservoir check valve 7) Cut off valve 8) Application choke 9) Release choke OPERATION OF C3W DISTRIBUTOR VALVE For effective functioning of air brake system, the distributor valve has to operate effectively during 1) Charging stage 2) Application stage 3) Release stage 1) CHARGING STAGEDuring charging stage the compressed air flows from the brake pipe and enters into the brake pipe chamber of main valve, cutoff valve and quick service valve. Due to this pressure the various valve get activated and perform as under MAIN VALVE Due to brake pipe pressure acting on top face of the large diaphragm, differential pressure acts on the main valve. As a result the hollow stem moves downward there by connecting brake cylinder to atmosphere. In addition these because of BP pressure at top of large diaphragm it press ring and trigger. This action unlocks the CR release valve by raising upward the locking rod.CUT OFF VALVE As brake pipe pressure enters into the cut off valve it flows through the solex jet and valve, (which is held upon due to action of BP pressure on bottom side of the lower diaphragm) to the control reservoir, as the CR & BP pressure equalizes, diaphragm assembly comedown and valve reach to lap position. The control reservoir pressure now also reaches to the upper portion of top diaphragm of quick service valve and the bottom portion of large diaphragm of main valve simultaneously, the auxiliary reservoir is charge d with BP pressure reaching from cut off valve chamber- via auxiliary reservoir check valve. ) APPLICATION STAGE EMERGENCY APPLICATION During emergency application the brake pipe pressure is reduced rapidly to 0 kg / cm2 by the driver’s brake valve. Because of this drop the position of the various valves will be as described below. MAIN VALVE: With drop in BP pressure to 0 kg / cm2 differential pressure acts across the large diaphragm. As a result the hollow stem is moved in upward direction and pushes the check valve there by opening the passage for entry of auxiliary reservoir pressure at top portion of main valve. This pressure then gets a way to break cylinder through limiting device.The brake cylinder thus gets charged with the compressed air. This pressure is known as BC-pressure. LIMITING DEVICE The auxiliary reservoir pressure, which entered into the top position of main valve, now enters the limiting device through the valve, which is held open. From limiting device air pressure now enter the brake cylinder. When the BC pressure rises to 3. 8 kg / cm2 the upwards force on the diaphragm lifts the guide and the valve at the bottom of the limiting device gets closed. Thus further entry of air into the brake cylinder stops. When the brake cylinder pressure reaches 3. kg / cm2 this pressure i. e. BC pressure act on Top face of small diaphragm of main valve ? Bottom face of upper diaphragm of cut off valve ? Top (small chamber) of quick service valve Now because of this BC pressure acting at main valve small diaphragm, the hollow stem is pulled down. As a result the check valve at top comes down to close stage and assume lap position with the hollow stem closing further entry of AR pressure. CUT OFF VALVE: In cut off valve the bottom face of the upper diaphragm is subjected to BC pressure because of which guide is lifted.Also the upper portion of lower diaphragm is subjected to CR pressure, which pushes the total assembly downwards. This action close s the valve off cut off valve, these by isolating it from control reservoir pressure. QUICK SERVICE VALVE In quick service valve BC pressure acts at the top of valve and control reservoir pressure act at top face of upper diaphragm, As a result the stem is pushed down BP pressure inside the DV is at â€Å"0† kg / cm2 the residue BP pressure from the bulb of quick service valve will flow back and vent to atmosphere with the BP line.GRADUATED APPLICATION During graduated brake application the brake pipe pressure is draped in steps by driver is brake valve. The movement of various valve assemblies is almost in the some direction as during emergency application, but their movement is comparatively less. In the main valve however after each application the hollow stem assumes the lap position with the check valve. In addition to this during graduated application the bottom valve of limiting device is held open to allow compressed air to enter into brake cylinder. When BC pressure reaches 3. kg / cm2 the bottom valve in the limiting device gets closed, similarly at the time of full service application as the BC pressure reaches 3. 8 + 0. 1 kg / cm2 within specified time, the position of various valve assemblies will be the same as described above. 3) RELEASE STAGE When the brake pipe pressure is increased in steps for graduated release of breaks the position of different valve is as described below. MAIN VALVE At the top face of large diaphragm as the BP pressure increases, the hollow stem is moved down ward leaving its lap position with check valve.The BC pressure thus finds a passage from top of hollow stem to exhaust to the atmosphere. This action reduces pressure on top of the upper diaphragm and the hollow stem engine lifts up to lap position. It closes the hollow stem top portion. The some cycle is repeated when BP is increased during next stage. In this way graduated release effect is obtained. CUT OFF VALVE; As the BP pressure increase the position of cut off valve remains similar as in graduated application i. e. the cut off valve will remain close isolating CR pressure from brake pipe pressure. QUICK SERVICE VALVEWhen the BP pressure is increased then as explained above from the main valve the BC pressure gets exhausted to atmosphere. This action gradually reduces the BC pressure. When BC pressure reduces to 0. 8 kg / cm2 during brake release, the force at the top of the quick service valve, becomes comparatively less than BP pressure present in Quick service valve. As a result the valve at top gets lifted thereby giving passage to blocked BP pressure to atmosphere with the exhaust of BP pressure the quick services valve of the distributor valve again gets ready for next brake application. MANUAL RELEASEDouble release valve provides for accelerated manual brake release when is particularly useful during shunting operation. A short pull on the lever of double release valve is all that is needed. This action opens the control re servoir release chock valve, which is then held open by the locking rod, venting control reservoir through the open control reservoir release check valve brings the main valve to release position and exhaust the brake cylinder pressure through the hollow stem. PASSENGER EMERGENCY ALARM SYSTEM It consists of two components: 1. Passenger emergency alarm signal device (PEASD) 2. Passenger emergency alarm valve(PAEAV)These two components in combination give an indication to the e driver that some passenger is in need to stop the train. The indication is transmitted from the coach when the passenger pulls the chain. Passenger Emergency Alarm Signal Device:- PEASD is a manually operated pilot vent valve. It is operated through mechanical force exerted by pulling the alarm chain provided inside the coaches for emergency use. Passenger Emergency Alarm Valve:- Passenger coaches are fitted with an alarm chain pull arrangement. Alarm chain is connected to the two PEASD which are situated at ei ther side of one end wall of the coach.PEASD’S are connected to the PEAV through a 10mm control pipe. BP pressure is fed to the PEAV through a 20mm branch pipe, in the event of alarm chain pull air is depleted form the control pipe connecting PEAV and PEASD causing BP pressure to exhaust through the 4 mm choke in the PEAV. This causes partial application of brakes. This drop in pressure in the brake pipe line is also observed in flow meter fitted in the locomotive for the driver to stop the train. LIFITING SHOP The main constructional and design feature of the ICF/RCF all-coil bogies, used on mainline BG coaches are briefly described as follows: |S.

Axles are located on the bogie by telescopic dash pot and axle guide assemblies. Helical coil springs are used in both the primary and the secondary stages. The axle guide device provides viscous damping across primary springs while hydraulic dampers are provided across the secondary stage.Dampers are protected against misalignment by resilient fittings. Isolation of vibration is effected by rubber pads in primary and secondary suspension. Deflection due to the tare weight is almost equally divided between axles and bolster springs. Weight of coach body is transferred to its bogie by side bearers consist of lubricate d metal slides immersed in oil baths. No vertical weight transfer is affected through bogie pivot and the pivot acts merely as a centre of rotation and serves to transmit tractive / braking forces only. BOGIE ASSEMBLY The bogie frame and components are of all-welded light construction with a wheel base of 2. 896 metre.The wheel sets are provided with self-aligning spherical roller bearings mounted in cast steel axle box housings. Helical coil springs are used in both primary and secondary suspension. The weight of the coach is transferred through side bearers on the bogie bolsters. The ends of the bogie bolsters rest on the bolster helical springs over the lower spring beam suspended from the bogie frame by the inclined swing links at an angle 70 . Hydraulic shock absorbers and dash pots are provided in the secondary and primary suspensions respectively to damp vertical oscillations. AXLE BOX GUIDE WITH DASH POT ARRANGEMENT Axle box guides are of cylindrical type welded to the botto m flanges of the bogie side frame with close dimensional accuracy.These guides together with lower spring seats located over the axle box wings house the axle box springs and also serve as shock absorbers. These guides are fitted with guide caps having nine holes of diameter 5 mm equidistant through which oil in the lower spring seat passes under pressure during dynamic oscillation of coach and provide necessary damping to primary suspension to enhance better riding equality of coach. This type of rigid axle box guide arrangement eliminates any longitudinal or transverse relative movement between the axles and the bogie frame. The quantity of oil required to achieve 40 mm oil lever above the guide cap in modified arrangement is approximately 1. 6 liters and in unmodified arrangement is approximately 1. 4 litters. AIR VENT SCREWSOn the bogie side frames, directly above the dash-pots, tapped holes are provided for replenishing oil in the dash pots. Special screws with copper asbestos washers are screwed on the tapped hole to make it air light. BOGIE BOLSTER SUSPENSION The bolster rests on the bolster coil springs- two at each end, located on the lower spring beam which is suspended from the bogie side frame by means of bolster-spring-suspension (BSS) hangers on either side. The two anchor links diagonally positioned are provided with silent block bushes. The links prevent any relative movement between the bogie frame and coach body. SPRINGS In ICF bogie, helical springs are used in both primary and secondary suspension.The springs are manufactured from peeled and centre less ground bar of chrome vanadium/chrome molybdenum steel conforming to STR No. WD-01-HLS-94(Rev. 1) CENTRE PIVOT ARRANGEMENT The centre pivot pin joins the body with the bogie and transmits the tractive and braking forces on the bogies. It does not transmit any vertical load. It is equipped with rubber silent block bushes which tend to centralize the bogies with respect to the body and, to some extent, control and damp the angular oscillations of the bogies SIDE BEARERS The side bearers are provided to support the weight of the coach. It consists of a machined steel wearing plate immersed in an oil bath and a floating bronze-wearing piece with a spherical top surface kept in it, on both sides of the bogie bolster.The coach body rests on the top spherical surface of these bronze-wearing pieces through the corresponding attachment on the bottom of the body-bolster. The whole arrangement is provided with a cover to prevent entry of dust in the oil sump. ANCHOR LINKS The floating bogie bolster which supports the coach body is held in position longitudinally by the anchor links which are pinned to the bolster sides and the bogie Transoms. One anchor link is provided on each side of the bolster diagonally across. The links can swivel universally to permit the bolster to rise and fall and sway side wards. They are designed to take the tractive and braking forces. The anchor link s are fitted with silent block bushes SILENT BLOCKThis is a synthetic rubber bush fitted in anchor link and center pivot of ICF bogies to transmit force without shock and reduce noise. EQUALISING STAYS This Device has been provided on bogies between the lower spring plank and the bolster to prevent lateral thrust on the bolster springs which have not been designed to take lateral force. These links have pin connection at both ends and therefore can swivel freely. BOLESTER SPRING SUSPENSION HANGERS (BSS HANGERS) In the secondary suspension the bolster is supported on helical coil springs which are placed on the lower spring plank is suspended from the bogie side frame through BSS hanger on hanger blocks. SHOCK ABSORBERSHydraulic shock absorber is also provided to work in parallel with the bolster springs to facilitate damping for vertical oscillations. WORKSHOP MAINTENANCE- BOGIE SHOP 1. Coach Lifting 2. Bogie cleaning 3. Bogie dismantling 4. Component cleaning 5. Attention to compon ents 6. Repair of components 7. Bogie assembly 8. Load testing and adjustment 9. Lowering of coach 10. Final adjustment OBJECT:- To study inspection & testing procedure of helical spring of coaches also suggest methods of improvement to reduce rejection & prevention from corrosion. USE OF SPRINGS:- Springs are used in the suspension system of coaches to absorbs the jerks developed during running of coach and provide comfort to the passengers. INSPECTION OF SPRINGS:- Springs are inspected during every POH.The inspection procedure is as follows: ? Springs which are lowered from the bogie are sent for the washing in spring section. Here the springs are dipped in the caustic soda tank for 12 to 16 hrs. so the oil, grease, scale etc are cleaned. ? Springs are then washed by the water jet. ? Visually inspect the springs for breakage, welding marks, cracks and corrosion pits. ? Shot peening for surface finish and fatigue relief of springs. ? Cracks are tested in magna flux machine. ? Codin g of springs ? Anti corrosive coating of red oxide, and painted. ? Load test ? Grouping SHOT PEENING:- Shot peening is done for the surface finish and fatigue relief of springs.In shot peening process small particles of chilled iron are blasted on the springs with high velocity, so these particles works as abrasive and take away a fine layer of metal with it. And the surface of springs looks clean. Rotary Table Type Shot Blasting machine is used for the shot peening process. This machine has two tables which alternately loaded by springs. The max. dia of job is 1800 mm and load carrying capacity is 2500kg.. At a time 25 axle box springs or 18 bolster springs can be shot peened by the machine. TESTING OF CRACKS:- It is nondestructive method of testing. Magna flux machine is used for detection of cracks in spring. The spring is first bathed by the solution of flouroscent, iron powder and kerosene.Then the springs are magnetized by the machine with clamping in machine itself. When the springs are magnetized, the springs are lightened by the ultraviolet lamp. Since the process is done in the dark room, so if the springs have cracks then this flouroscent shines which penetrated in the springs due to crack ness and detection of cracks is done so the spring will rejected. LOAD TEST:- After coding and coating of paint the springs are sent to the load test. The springs are tested for the 2000ton load and this load is kept for 1 to 2 minutes. If the springs can sustain this load with limited deflection then springs are selected else rejected. METHODS OF IMPROVEMENT:- Use the springs made of standardized material as suggested by Railway’s Standard. ? The springs should be made of fine grained spring steel. ? Use the springs manufactured by the authentic company and also notice the manufacturing process of springs should be according to the standardized method. ? 100% of springs should be checked for all the test procedure. PREVENTION FROM CORROSION:- Springs shoul d be coated with the anticorrosive paint and black bituminous paint. ———————– Technician 2 Technician 1 Senior technician Supervisor Supervisor Junior Engineer 2 Junior Engineer 2 Junior Engineer 1 Junior Engineer 1 Section Engineer Senior Section Engineer (SSE) Helper
