Dealing With Physical Abuse

The Struggle Physical Abuse Brings People all around the world have suffered from being abused verbally and physically, causing a struggle because they don’t know how to handle these types of situations. In the short story Runaways by Karen Brennan, the main character Lou is physically abused by her husband, which leads Lou to run away, causing problems between friends and family. What are you without loved ones? When you really care about someone you will give an arm and a leg for him or her but once they cross a line they shouldn’t, it feels like the world is supposed to end.In Lou’s situation this is exactly what happened to her. She gave her entire life to her husband and her children. Unfortunately her husband didn’t care about her feelings and cared more about what he wanted than what would keep her happy. Physical abuse in a relationship is a key factor of failing marriages. Lack of communication can lead to physical abuse. Throughout the time that Lou and her husband have been married, they have been through a lot. One thing that might have started all their arguing besides his drinking problem may be that they â€Å"have difficulty talking to each other†(Brennan,501).Lou states, â€Å"My husband didn’t always beat me. In the beginning he was just irresponsible. I could live with that. He drank too much and in the worst times he drove too fast with the babies in the car†(Brennan,501). Lou’s husband beats her so often, she is afraid to go to sleep. When her husband was drunk he became a whole different person, â€Å"he was a maniac when he was drunk†(Brennan,501). â€Å"Its unfair the advantage that men have†(Brennan,501) because woman should be able to stand up for themselves without worrying about what the guys reaction will be.Lou is a woman who will put others before herself. She is a mother of four children and wants everyone happy. For instance, a lot of mothers’ first rea ction to their children crying is to beat them and tell them to â€Å"stop whining†. Lou has been beaten by someone she truly loves so why would she want to beat four people she loves unconditionally, her children. Lou states, â€Å"I am not one of those mothers who turns around in the car and swats the kids on the legs and tells them to shut up. I have never believed in that. When they whined, I told stories.I told them about a family who sailed away in an orange balloon†(Brennan,501). Lou had hit her breaking point and had to runaway from her problems. But is running away the answer? Often people who are physically abused turn around and abuse others. For Lou, it was a different story. She was not a young adult who abused her children because her husband abused her. Many people take their anger out on others because it is a way to make themselves feel better. Lou possibly could have felt pressure to raise her four children with her husband being involved.Lou was stro ng enough and didn’t stay in an abusive relationship just for the children because she knew leaving was the best decision for her at the time. Through all the ups and downs Lou went through with her husband in the end she felt like she was left with nothing. â€Å"a woman without a husband is like an ocean without a sea†(Brennan,500). Its hard being happy if you don’t have the people you cherish most in your life around you. A person can struggle with a bunch of emotions and if you don’t have the support of people that care about you, the situation gets a lot harder.When you are surrounded with people that want the best for you, then you will get though your struggles with someone by your side, not alone. I personally know someone who went through something very similar from what Lou went through. My cousin who is now 25 years old has been dealing with family problems ever since she was about 10 years old. I have heard all these stories about my cousin an d her family from my parents. I was always curious and wanted to know what was happening but it was not my place to ask questions because it might be a sensitive topic for her.Her father was a heavy drinker which caused him to be very angry not only friend friends but especially with his family. My cousin Kelley was the youngest of the two kids. She has an older sister who was 4 years older than she is. Night after night her father kept drinking excessively. The family knew what was coming along with his drinking, his anger. One night it got really bad, he yelled at Kelley for the littlest things, things that were not even a big deal. One time, she didn’t wash her plate after dinner because she was too tired and wanted to go to bed.He became highly upset and rushed into her bedroom, slapped her, and told her to get up and clean her plate. Each day he got worse and worse. After a couple years went by Kelley, her mom, and he sister could no longer handle him and his drinking pr oblem. They moved out when he was at work so he could not say anything about it. The girls moved far away and did not tell anyone where they were going because they did not want their father to find out. They knew he would make a big deal about it. Three girls living on their own trying to survive must have been hard.Having a main man in their life was their leading factor to surviving. Without her dad paying for everything and supplying for the family, it’s difficult for the girls. Somehow her father found out where they were and made them come back. They decided to give their father one more chance, thinking that things would be different but they only got worse. He thought they would leave him again so he tried to be more protective which only caused his anger to be worse than it already was. As Kelley matured throughout the years she realized she no longer wanted to have her dad in her life at all so she lost all contact with him.She got her own apartment and did almost a ll her daily actives on her own. After everything that happened with her dad, she didn’t want to depend on anyone else but herself. This made it difficult for Kelley to keep close friendships with her girlfriends because after her father, she thought that everyone she truly cared about would let her down like he did. Kelley’s fear of having to abandon ones she love caused her to have little friends. She was afraid to trust anyone at all because she believed that friendships and relationships don’t last forever.Later when Kelley became a young adult she realized that she could not go on any longer not having her father in her life and having little friends that she can count on. Being on your own is tough. So Kelley allowed her father to re enter her life but not fully be involved 100%. She realized although she had been through a lot over the years, having her dad around again was exactly what she needed to be happy again. As the years go on, you find out who yo u need in your life and who you would be okay without. I thought that Lou and my cousin Kelley’s story were similar due to running away from their problems.Although Lou was physically abused and Kelley was verbally abused their problems with the men in their lives bring their two stories together. Not having a close relationship with someone who means the world to you has to be really hard. Especially for Kelley, being so young and thinking you dad would be someone you would look up to as the years went on. Her father ended up being someone she never thought he would be, which had to of been beyond upsetting. As for Lou, the man who has been the love of her life for years now and has children who look up to him is not the type of father they though he was going to be.Its hard putting all your effort into someone and believing they are going to give their best to you and then be let down. Being let down is very hurtful and can cause someone a lot of pain, for instance Lou and Kelley. Although Lou and Kelley did not end with the same feelings at the end of both of their stories they still dealt with the same process.

Work Satisfaction and Motivation

————————————————- THE RELATIONSHIP BETWEEN REWARDS, RECOGNITION AND MOTIVATION AT AN INSURANCE COMPANY ————————————————- IN THE WESTERN CAPE ABSTRACT Increasingly, organizations are realizing that they have to establish an equitable balance between the employee’s contribution to the organization and the organization’s contribution to the employee. Establishing this balance is one of the main reasons to reward and recognize employees. Organizations that follow a strategic approach to creating this balance focus on the three main components of a reward system, which includes, compensation, benefits and recognition (Deeprose, 1994). Studies that have been conducted on the topic indicates that the most common problem in organizations today is that they miss the important component of recognition, which is the low-cost, high-return ingredient to a well-balanced reward system. A key focus of recognition is to make employees feel appreciated and valued (Sarvadi, 2005). Research has proven that employees who get recognized tend to have higher self-esteem, more confidence, more willingness to take on new challenges and more eagerness to be innovative (Mason, 2001). The aim of this study is to investigate whether rewards and recognition has an impact on employee motivation. A biographical and Work Motivation Questionnaire was administered to respondents (De Beer, 1987). The sample group (N= 184) consists of male and female employees on post-grade levels 5 to 12. The results of the research indicated that there is a positive relationship between rewards, recognition and motivation. The results also revealed that women and employees from non-white racial backgrounds experienced lower levels of rewards, recognition and motivation. Future research on the latter issues could yield interesting insights into the different factors that motivate employees. ————————————————- Notwithstanding the insights derived from the current research, results need to be interpreted with caution since a convenience sample was used, thereby restricting the generalizability to the wider population. ————————————————- ———————————————— ———————————————â€⠀- DATA GATHERING INSTRUMENT For the purpose of this study a quantitative methodology was followed and a questionnaire was used as the measuring instrument. According to Leary (2004), the major advantages of questionnaires are that they can be administered to groups of people simultaneously, and they are less costly and less time-consuming than other measuring instruments. The data gathering techniques used included a biographical questionnaire and the Work Satisfaction and Motivation Questionnaire as set out by De Beer (1987). ———————————————— BIOGRAPHICAL QUESTIONNAIRE The biographical questionnaire was a self-developed questionnaire that incorporated the following personal information of the respondents, gender, home language, marital status, age, race, job classification, education, qualifications, job grade and tenure.

The questionnaire consisted of nine dimensions that impact employee satisfaction and motivation. Refer to Appendix 3. ————————————————- THE NINE DIMENSIONS OF THE QUESTIONNAIRE According to De Beer (1987) the nine dimensions are as follows: 1. Work content probed the respondents’ feelings about the type of work they do. 2. Payment probed respondents’ satisfaction with their salaries. 3. Promotion probed for the opportunity that the organization offers for promotion. 4. Recognition probed whether the respondent was receiving the recognition and feedback for the jobs they perform. . Working conditions were probed as the fifth factor and looked at opportunity to mix with colleagues and interpersonal relations. 6. Benefits looked at whether the benefits such as pension, medical schemes and leave were satisfactory. 7. Personal probed the respondents’ feeling s towards their job. 8. Leadership or supervision probed the level of satisfaction with the manager. 9. General probed if the respondents’ had considered alternative employment, and hence their level of satisfaction with the organization. Appendix 2 ————————————————- BIOGRAPHICAL INFORMATION .

COURTROOM OBSERVATION AND NARRATIVE ASSIGNMENT Essay

COURTROOM OBSERVATION AND NARRATIVE ASSIGNMENT - Essay Example When I entered the courtroom, the following people were in attendance: the judge, defendant, two of police officers, plaintiff and two attendants. The case was about drugs. I noticed that the judge was using a computer to process information about the court proceedings. In my own opinion, I think it is good to use new information and communication technology such as computers when dealing with such cases since it is easy to process and store information. In other countries, they do not use such technology. I noticed that the judge talked with confidence when she was asking the defendant some questions. She never ignored the defendant and she paid attention to everything he said. The most interesting thing that caught my attention was the way the speaking was organized. When the defendant finished speaking, the judge kept quiet briefly. After that, she started speaking. The process was very efficient. If I compare that with my country, there are clear distinctions. In my country, whic h is Saudi Arabia, there are a lot of loud sounds in court. Sometimes, you do not know who is talking. It looks like chaos. Here, the hall was so quite. No talked randomly. However, I did not really understand the details of the case because it was continued from an earlier hearing. There was some information I had missed. Another thing that I did not understand was that I did not see a defense lawyer representing the defendant. I just saw the plaintiff. When the judge was talking, the defendant received the verdicts quietly. The defendant had some files he was using to research some information to prove his innocence. The judge was giving the defendant enough time to talk and to research by his files. I believe that is fair to give the defendant an opportunity to defend himself. I later understood what the case was about. It was about drugs. The defendant was trying to implore the judge when he said, â€Å"I wanna go back home. I have a

Lessons from Tribal People - Essay Example According to ManKiller and Lyon tribal mind set is different from Other Americans as they are pure in their thoughts and feelings. They have the gratitude to life, nature and God. They value relationship and hard work. As per ( Spaid )â€Å"Mankiller says the Cherokees, who dont live on a reservation, are not as isolated and have more industries than most Indian peoples†. Mankiller suggest that the universal nature of tribal people is that they value their tradition and culture enormously.Living a simpler tribal existence means staying away from complexities of urban life. The life in the modern world is just a way to destroy nature. In the modern world, the natural resources are exploited and man has less consideration for nature and humanity. According to (Jayson,) â€Å"Primitive people lead self-sufficient lives that do not destroy the biosphere that supports them† .Simple tribal life is pure and living in alliance with nature and respecting earth its creature and God.

Explain the evolutionary mechanisms that can change the composition of Essay

Explain the evolutionary mechanisms that can change the composition of the gene pool - Essay Example In addition, certain evolutionary processes such as natural selection and genetic drift cause a decrease in these genetic variations (Colby; Lerner). Mutation is a phenomenon by which chemical changes occur within the DNA which in turn alters the sequence of the gene resulting in a mutant gene. The extent to which the DNA is altered depends on the type of mutation which could be a point mutation in which on letter of the genetic code is changed, insertion or deletion of a stretch of DNA within a gene or inversion, translocation or duplication of a segment of the DNA. Such mutations can produce truncated proteins, abnormal proteins or a silent mutation that does not introduce any change in the resulting protein. Hence a mutation can have both a deleterious as well as a beneficial effect on the organism (Colby; Lerner). In addition to mutation, gene expression within an organism also depends on the built-in natural variation that occurs within a gene pool. Not all genes within an organ ism are expressed as only those which are activated produce their respective proteins and are hence expressed in the phenotype. Such selective expression of genes is also responsible for the variations observed between each individual (Veith).

Project Planning and Project Managment Research Paper

Project Planning and Project Managment - Research Paper Example Despite the risks, project management ensures that tasks are completed successfully to their full requirements. Project management should be started earlier before committing resources and continue to the completion of the task. Companies face numerous opportunities to make their projects viable. There are also numerous techniques that can be used in making the project a success. However, successful project management requires the application of good principles rather than implementing available techniques. The principles are normally derived from experience and are valid across all projects. The success of any project is dependent on how a company applies the principles of projects management. The principles of project management include: a) Identify your business and mind your own business. Sigma has its business of providing information technology solutions across the world. The company should then make a selection of projects that are viable to the business. According to research studies, half of project management is about paying attention. Sigma should learn and apply the best practices. b) Understand customer needs and requirements and put them under version control. Sigma should gather comprehensive information on customer requirements and document the requirements under version control. ... d) Create a competent team with clear tasks. The projected team should include trustworthy and competent members. The team should have their tasks well defined and provided with the necessary working tools. Sigma is expected to offer training to team members to ensure that the project is carried out according to plans. The team should have a team leader and any misfits within the group should be removed. e) Make a follow up on progress and conduct reviews. Projects may have faults and this can only be identified by tracking the progress of the project and review the progress frequently to identify potential loopholes that may be present in the project. The progress should be viewed in a very wide spectrum and pay attention to indicators in order to identify problems before they go out of hand. f) Use baseline controls. Managing the project requires a cost and schedule baseline tracking in handling changes. The changes should be managed deliberately. Sigma is expected to measure probl em areas and apply quantitative methods in tracking the progress of the project towards providing solutions to the identified problems. g) Note down important information and share it among team members. It is important to record requirements, design and management structure and the plan for the project to ensure the improvement of concepts and ideas. Proper documentation ensures that the project has baseline controls and a process that can be revisited. Decision and their rationale should be recorded for future application. h) Conduct tests on various cases. A project work requires decisions that have been tested and their potential outcome known. This reduces uncertainty in conducting some activities. Sigma is expected to develop test cases early enough in order to

Themes of Crhistian Faith Essay Example | Topics and Well Written Essays - 1000 words

Themes of Crhistian Faith - Essay Example For how can one fully know or predict the end when he employs mind closed at recognizing paths that wind to a triumphant outcome. As I see it with his tone of reactions on course placement, clearly, he hasn’t been properly acquainted to an in-depth assessment of theology or his limited former knowledge might have been brought across at the wrong approach so there is not a way he can be expected to entertain the course in the competitive framework of the academe. Because the formation of his argument lacks structure, rational profundity and barely sounds discerning, I am gradually convinced to disagree with his vie. I find it sufficient as well to disagree on the ground that due to reluctance, he has not at all considered looking over a few lessons which may yield to recognition of advantages other than academic. Mr. Dawkins’ position is weak, having sought no development from an educated process of arriving at a decision and I suppose that every person with similar influence is not likely to figure any relevance in a religious subject and would amount to the same set of reasons that draw support based on the common philosophic undertakings and working principle in which science, in the absence of God, lies at the core. Theology, in its basic essence or with lengthy technical definition taken off, is by terms of origin, a word (logos) of god (theos) from which to explore limitless possibilities how it may be done so to obtain answers required upon discovery of innumerable questions with rising complexities, since no physical evidence is available to testify how or what spiritual entity and faith are in form. So then accordingly, one can at least claim that theology, as a study of god, proceeds to be identified as making an abstract concept raise to the level of tangibility, or reality, which we know must take a definitive form if individual truth allows its perceived

English class - Essay Example Assassinations regularly feature in the game. Fire fighting and flying helicopters are simulated. In the later releases, especially after the grand theft auto 2, players are forced to overcome extreme and unfortunate events like being left for the dead and betrayal. This becomes a motivation for advancing through the criminal ladder in the game leading to the triumph of the character by the end of the story line (Bogenn 79). The game also involves driving taxis and carjacking. The grand theft auto III makes violence to be more realistic and practical to children. The players have opportunities to pay for prostitution services with the aim of recovering health. Then the players can kill to recover the money. The game is seen to be moving from the traditional heroic roles offered by the games to illegal activities. The players are forced to commit a wide variety of crimes (Kutner and Olson 41). The grand theft auto displays a notion where the player only faces short term consequences. In the game, the players end up killing policemen and soldiers. Grand theft auto is said to have controversial content especially with regard to children. The episodes of the game are said to have a grave impact of the children’s behavior. The video game is linked to aggression and addiction to vices and violence. A study in 2001 showed that contents of grand theft auto and similar games lead to increased aggression less pro-social behavior among children (Bogenn 79). The violence practiced in the games makes children be comfortable with antisocial behavior like ignoring the rights of others. Grand theft auto is also said to have positive impacts on children. It’s been argued that it trains children to be team players, competitive and that the video characters are not reflected in the real life situation. Grand theft auto leads to both long term and short term aggressive and violent behavior (Kutner and Olson 41). The video game depicts women as sex objects

How Does the Iranian Nuclear Program Affect the GCC Countries National Research Paper - 1

How Does the Iranian Nuclear Program Affect the GCC Countries National Security - Research Paper Example the United States and the United Kingdom proved that Iran had the economic strength to support its nuclear program and so the worry arose on the consequences of such an expedition on the security of the world and that of the GCC countries (Hagel & Loeb, 2014). The resistance that the whole project has faced has been as a result of the concerns that such a serious and delicate process can cause to the whole world. While the GCC countries feel that it is their right to take care of the world by controlling such a process involving nuclear power, the Iranians feel that the concerns being raised are pre-textual and malicious and aimed at preventing it from getting the nuclear power that it needs urgently (BBC News, 2014). According to Hagel & Loeb, 2014 the Gulf Cooperation Council (GCC) has expressed its concerns over the Iranian nuclear program. The GCC countries include the Kingdom of Bahrain, Kuwait, Oman, Qatar, The Kingdom of Saudi Arabia and The United Arab Emirates. These countries possess a significant economic interdependence both in economic, politics, culture and also in religion. Since Kuwait, Saudi Arabia and the UAE are major Oil exporting hubs, they have a significant economic dependence and setting of policies that govern the oil trade. On the other, Qatar is well known for producing natural gas and since this lies in line with the oil production it serves as a uniting factor among the countries. Almost all citizens in the GCC countries are Muslims which serves as a uniting and common factor to help unite them further. The political status of the countries in the GCC umbrella is based on the Islamic religion as it is the dominant one in the region. Though Iran is not a member of the GCC, the nuclear program has been viewed as a direct threat to the GCC countries and so they have resisted it in one accord. The national security of any country involves maintaining the survival of the state through the use of its economic power and setting of foreign

Advantages of supply chain management Essay Example for Free

Advantages of supply chain management Essay One is cost advantage. Companies that have implemented supply chain management have a 45% supply chain cost advantage over their competitors. [1] Price of raw materials and end product are optimized due to collaboration between two parties. The sharing of vital information in the early stage of development, and the effective communication of methods and requirements allows parties within the supply chain to effectively benefit each other in terms of cost. Another is faster time to market. Companies met their promised delivery dates 17% faster than their competition. [2] Through early information and forecast, suppliers can also efficiently design their production and implementation process through collaboration. This allows supplier to reduce the lead time to produce their products within the supply chain. Disadvantages of supply chain management over traditional competitive procurement processes. First is the difficulty of maintaining supply chain relationship. Supply chain relationships are probably the most fragile and the most susceptible to breaking down. [3] This is because a poor relationship at any part of the supply chain can cause major problems to the entire supply chain. In today’s global market, the customers have the power over the suppliers. Everyone else in the supply chain must quickly satisfy the demands or else face the possibility of loosing them. Another disadvantage is the need to share vital information for collaboration purposes which leaves a company vulnerable to illegal copying of ideas or methods. Although these can be safeguarded by proper agreement between parties, but the forces of market competition may compel violations of agreement intentionally or unintentionally.   If supply chain management is actually a superior way of managing procurement and production, how (if at all) does that modify any of the economic `big ideas` we examined in Module 1?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Supply Chain Management plays a major role in the concept of supply and demand. With parties closely related through collaboration, the identification of demand which is needed by the suppliers to support the collaborative company is easy, allowing suppliers to maximize profit given the level of demand. On the side of the collaborative company, the control of supply of raw materials is easy, which again would allow them to optimize profit. References: Ferguson, B. (2000).

Singapore Airlines

Singapore Airlines Executive Summary: Singapore Airlines Singapore Airlines was established as a separate entity in 1972, when it split up with the Malaysia-Singapore Airlines. However, if the actual history of the formation of the company is considered, then, Singapore Airlines was founded in 1947, when it was inherent to the Malayan Airlines. In those days, just three flights per week, to Kuala Lumpur, Ipoh and Penang, were all that the people in Singapore were privileged to. But, there were very fast developments in the situation in a span of two decades. During this period, Singapores Kallang Airport gained an international exposure and started making huge additions to its fleet. Soon after the birth of the Federation of Malaysia on February, 1963, the Malayan Airlines came to be known as the Malaysian Airlines, and in 1966, it was renamed the Malaysian-Singapore Airlines. But, in 1972, fifteen years from the day it was founded, Singapore Airlines split up with Malaysian Airlines and acquired a separate identity. This split however, helped the airlines to take its decisions itself and the company was able to implement many innovative schemes which helped it not only to gain a greater popularity, but also to expand its business by a far greater extent than its Malaysian counterpart. The airlines that started off with just a single plane that took off just thrice in a week some six decades ago, has today managed to develop quite a large and advanced fleet today, that covers 93 destinations in 38 countries. However, the success of any organisation depends upon a number of factors. Inspite of thorough and regular research programs, many organisations havent been able to succeed in their fields. There still remain some intrinsic problems that many fail to notice initially but which become prominent as time passes by. This paper is a case study to identify any such problems that might hinder the successful working of an organisation and what the possible ways to avoid them could be (The Creation of Singapore Airlines, 2009) Chapter 1: Organisational Structure and its Basic Elements A. Organisational Structure Organisational Structure is an ordering among a group of people who coordinate among themselves for achieving a predetermined target. A good organisational structure plays a major role in the maintenance of discipline in a company and hence, is very important for a smooth run, because a proper and clear hierarchy not only distinguishes among the different duties that different people should perform but also makes the best use of a persons potentials. An organisation could be structured in either a hierarchical (top-down) or a functional manner (managed by different heads in different departments), according to the size and the diversity into which a company indulges itself (Organizational Structure, n.d.). The Singapore Airlines is one of the biggest in terms of turnover as well as coverage in the airlines industry. But, the secret behind it is a good organisation. It follows a hierarchical organisational structure being a subsidiary of the Singapore Government and a number of vice-presidents underneath responsible for a variety of operations. The Singapore Airlines had long been exemplified as one with a very flexible organisational structure that had forever helped it to emerge out of contingencies. But, the more important part for the success behind an organisation is the relation that exists between its various elements. B. Elements of Organisational Structure (i) Complexity of the Organisation The Singapore Airlines today has a strength of about 2000 pilots, 7000 operating cabin crew and 170 ground staff. In addition, to the core work of commuting people, it also is involved in a variety of activities aimed towards social welfare and environmental protection, for which the company employs a large number of executives The company also indulges in researches aimed at improvement of its services and enhancing its circle of operations. The company had historically been a pioneer in the adoption of new technologies in the aviation industry in fields of both flight and in-flight facilities. It became more evident when the company became the first to own and operate the largest aircraft in the world, A380, in 2007 between Singapore and Sydney (Dooley, K. 2002, pp1) (ii) Centralisation of Structure For Singapore Airlines, although the ultimate power rests in the hands of the Government of Singapore via the Ministry of Finance, the government had always been very strict about its non-involvement in the management of the company and thus has recruited a number of efficient vice-presidents who are assigned to the proper running of the organisation. Thus, theoretically although it could be said that the firm has a centralised structure, yet practically this can not be supported on a firm ground. (iii) Formalisation of Structure Formalisation implies the degree by which an organisation formalises its process of setting rules, regulations and restrictions on its members. The Singapore Airlines had never been an autocrat in the field but had rather focused on keeping the regulations low so that its employees are comfortable in the environment they work and feel free to propose any probable changes that might be in favour of the organisation. Keeping the rules and regulations minimal have added to the productivity of its employees and has helped it to grow so fast. Chapter 2 Dimensions of Organisational Structure: Mintzbergs Theorem Henry Mintzberg identified six different types of organisational structures suitable for different types of organisations passing through different phases, namely Simple Structure, Machine Bureaucracy, Professional Bureaucracy, Division Organisation, Innovative Organisation and Idealistic Organisation. At the beginning, the organisation adopts a simple structure that is not being able to afford a highly organised hierarchy in the initial stage. As the firm starts growing, it adopts a more organised structure according to the type of business. Machine Bureaucracy would be ideal for those firms that are more dependent on researches and innovations, while Professional Bureaucracy implies the presence of a large number of specialists in the organisation. Division Organisation is suitable for those that involve themselves in a number of products, for which the coordination between the various links in the middle management becomes important. Innovative Organisational Structure is that in which formal training is imparted to the employees for the efficient running of the system. Lastly, the Idealistic Organisational Structure is that in which the company fixes a set of policies that becomes the company motto and everyone is bound to adhere to it. The last five organisational configuratio ns being discussed represent a proper hierarchical or functional structure and develop only after the company attains a certain level of growth (Organisational Configurations, 2009). Singapore Airlines is a mature airlines firm that follows a hierarchical organisational structure. However, the company cannot be said to be following a single configuration, but rather it is inclined to both Machine Bureaucracy and Professional Bureaucracy. None of the other structures are found to exist within the organisation neither does it indulge itself in a large variety of products so as to follow a Division Organisation, nor does it impart any formal training to its employees who are already trained at the time of recruitment (the case of Innovative Organisation) and nor is there any such strict company motto that is intrinsic for an Idealistic Structure. Rather, the companys nature to employ already specialized people in its organisation, as is the case for all aviation firms, and its involvement in a large number of research projects meant to promote both its internal and external affairs proves that the firm follows a Machine Bureaucracy as well as a Professional Bureauc racy type of organisational structure. Chapter 3 Determinants of Organisational Structure: Organisational Goals Organisational goals are those that help a company to smoothly run its operations by avoiding any chaotic environment and giving a direction and motivation to the company. Setting organisational goals help a company to know the exact targets that it needs to achieve and plan a strategy that would be most appropriate to acquire them. In other words, planning of organisational goals help a firm to act in a more effective and efficient manner. The goals that a company sets mainly are based upon two key facts ends focus and means focus. The natures of these goals however keep on changing depending on that of the team (Setting Organisational Goals, n.d.). The chief organisational goals of the Singapore Airlines had been the achievement of a stable and a pioneer position in its respective field of operation. The company had indeed been the first in launching a number of new programs, new techniques and devices. The most notable is the fact that the airlines became the first on October 25, 2007, to own and operate the worlds largest commercial aircraft the A380 between Sydney, Singapore, London, Tokyo, Paris and Hong Kong. The airlines company also researches upon the changing tastes of its consumers and keeps on changing its customer services accordingly. It has enhanced the entertainment services, food services and other in-flight services according to the changing tastes of its customers and this is the reason why a large number of people had been loyal to the company for many years. Moreover, it had been making additions to its fleet on a regular basis so as to ensure maximum coverage in its operations, both for the convenience of the people as well as helping itself to earn greater profit margins. Chapter 4 Organisational Effectiveness There are four approaches that judge the organisational effectiveness, namely goal attainment approach, systems approach, strategic constituents approach, balanced scorecard approach. The goal attainment approach identifies the goals of the organisation and paves a path to achieve them. It should be the ideal approach when goals are clearly measurable with respect to time and the organisations capability. The greatest advantage of this criteria is that it can be very straight-forward, provided the goals are properly specified. The Systems Approach is that which utilises the scarce resources derived from the surrounding environment, effectively, for the accomplishment of organisational goals. This approach should be ideally used when there is a clear link between the inputs used and the output produced by the company. The main advantage of this approach is that, before deciding upon the company goals, it assesses the impact that the completion of the targets set by the firm would create on the society and the environment. The Strategic Constituencies approach is that which stresses upon the successful completion of the demands of one or more constituencies internal to or an external of the organisation. This approach is adopted by an organisation in case the constituencies have a very strong influence in the firms operations. The benefit of this approach is that the firm evaluates its budget and compares it with a number of competing ones before it pins up on one or more organisational goals. A balanced scorecard approach to assess organisational effectiveness should be adapted to judge whether the small-scale operations in a firm are aligning with its larger-scale activities. This approach is the ideal one to evaluate a firms long-term interests. Thus this approach helps in aligning the firms direction of operations accordingly after citing the goals in a proper manner. Since it is an approach emphasising on the long run, so, it must be very patient in its activities. It is a widely known fact that any organisation that wants to sustain in the industry and create a stable and strong ground for itself, must focus on the long-term interests. Singapore Airlines is one such firm that had always aimed towards long-run gains and that is the reason why it is at present in the most stable position compared to all other aviation firms in Asia. Again this particular firm had always aimed at becoming a pioneer in its field of operations and had in most cases been able to achieve its aim. This needs a true understanding of the firms capabilities and the constraints that might hinder its operations, before it sets a goal for itself. Thus, it could not be said that the firm had been a loyal follower of a particular approach to measure its organisational effectiveness. Rather, the approach it had been following could be separately identified as having the characteristics of both the goal attainment approach and the balanced scorecard approach. Chapter 5 Structural Problems Whatever be the organisational structure adopted by a company, in most cases, it cannot be problem-free. Especially in a hierarchical structure, the main problem is that of communication. The decisions that the bureaucrats at the top of the organisation make take a longer span of time to trickle-down to its grass root workers. Moreover, because of this lack of communication, the ambience in the organisation could be very chaotic thus disturbing the smooth functioning of a firm. However, any such problem is not expected to arise in case of Singapore Airlines since the topmost position is held by the Government of Singapore that has strictly kept itself aloof from all operational activities of the firm. Instead, it has divided the different departments and employed a number of vice-presidents as the heads of those sections. This eases out the process by a large extent. Another probable problem that might arise in a particular organisational configuration is that of very restrictive rules and regulations that often confine the activities of its employees under the impression of being very disciplined. The employees in such firms neither get enough enthusiasm to work and nor to innovate. But, Singapore Airlines had been very vigilant of this fact and had always allowed its employees to have their own space which had helped the company not merely to grow but also to become one of the fastest growing and innovative in the industry. Conclusion At a time when the Asian aviation industry on the whole is at the verge of a collapse, the Singapore Airlines appears to be its only ray of hope. The company had always made provisions for a flexible organisational structure by adjusting its management force according to the economic situations. Since it belongs to a small country, the airlines had always made the best possible use of the globalisation factor and thus had responded to regional crises on a comparatively low scale. For example the present downfall that has almost gulped the Asian aviation industry, is mainly caused by an initial surge in the flow of wealth in the pockets of the Asian middle-class and then a sudden decline in the foreign exchange rate in terms of dollars when most of the debts were denominated in terms of dollars. Moreover, the immense rise in fuel costs is also one of the reasons. However, Singapore Airlines had strategically handled its business in a way that nothing other than a global meltdown could affect it. It had already spread its wings to a large number of countries and already had acquired a huge number of loyal customers through some unique customer services that it provides (Asia Pacific Management News, June 24, 1998, para 2 9-11).

Free Othello Essay: The Disintegration of Othello -- Othello essays

The Disintegration of Othello Shakespeare's Othello is a play with unique characters. One such character is the one for which Shakespeare names his play. In the play, Othello disintegrates from a confident leader to a homicidal murderer. Linguistic changes throughout the play attest to this theory. In the opening scenes, Shakespeare portrays Othello as a noble character. When Brabantio seeks vengeance (for "stealing" his daughter) on Othello, Othello expresses his actions will "tongue out his [Brabantio's] complaints" (1.2.21). Thus he shows his calmness against the verbal slander of Brabantio. Throughout this scene, Othello remains calm and confident. Moreover, he humbly tells the story of his relationship with Desdemona. He does not flaunt the situation over Brabantio but speaks modestly. In the next act, Othello maintains his calm demeanor. He speaks poetically of seeing his "fair warrior" Desdemona (2.1.210). Later in the scene, Cassio fails at his military duties. Even though this deeply hurts Othello, he keeps his calm. He lovin...

Women in Ancient Civilizations Essays -- essays research papers

The role of women in different civilizations, even though on different spectrums of the world, had many similarities and only a few differences. Women in these four civilizations: Greece, Egypt, China, and India faced many of the same hardships, struggles, and prejudices. Some of this treatment of women didn’t even end until present day (1920’s). In some of these civilizations women were able to rise up somewhat in their communities but it didn’t come without some kind of interference. When it came to the rights of these women, they really didn’t have any at all. In Greece women were considered to be second class citizens at best. All women were forbidden to own property, inherit their own name, vote, or attend political debate. Men viewed them as nothing of real importance. To them they were irrational, fearful, and only to be used for their physical desires. They were considered to be the ward of a man (Sacks 263). Women in Egypt were treated fairly well compared to the others. They shared the same legal and economic rights as men they were capable of owning land, slaves, and could acquire possessions for themselves in many ways. Elite women did have more rights and opportunities than the nonelite but they were both very fortunate. Regardless of class though, all women had only a few main concerns and expectations. They were all expected to get married and raise a family, maintain the management of the household, and bearing and rearing children (Harrison 510). The rights of women in China and India were similar as well. In India the rights of women have barley changed since ancient times. Women in this country are not allowed to own property, show their faces in public, and are the complete property of a man (www.geocities.com/hinduism/hindu_women.html). The women of china were also inferior to men. For around two thousand years they lived under the rules and laws set by Confucius. The Confucius doctrine said that women weren’t equal to men because they were unworthy and incapable of an education. These women were the property of men from birth till death (Andrea and Overfield 82-90). Their rights were not only limited to their families though in some cases there were actual laws passed that limited the rights of women. In ancient times The Code of Hammurabi for example had several laws that restricted women when it had to do with marriage and what a hus... ...ng their own property, they were encouraged to join athletics such as gymnastics, and some rose to be estate managers. They were even capable of participating in religion and could leave the house during holy days. During the Hellenistic age the treatment of women started to lighten up. Many started to realize that they have a greater value including their intelligence (Sacks 264). Chinese women didn’t start to rise up until the 20th century when communism began. Communists believed that women were equal to men; they felt that it would help the population of china to thrive (Dillion 346). The women of Egypt were treated well and did have a say in many of the things that involved them so they didn’t rise up too much more. Unfortunately for the women in India they have never truly risen up. They are still victims of being very subservient to men. In conclusion, women in all of these cultures have faced many hard times. Either from their community, husbands, fathers, or any man they were put down and restricted but though it all many women found a way to rise up through it all. There is still a long way for women of other culture to go but times are changing and anything is possible.

Beauty essay Not Finished

By establishing unattainable standards of beauty and bodily perfection, the media drive ordain rye people to dissatisfaction with their body images. This dissatisfaction can result in resort s to drastic measures, and even disorders of behavior, as people try to achieve these unreachable g oils. While most people assume it is only women who are affected by this, the fact is that of the estimated 8 million Americans who suffer from eating disorders, one in et n is male.While for women the anxiety centers around magazines, for men, they see the images of ultramarine action heroes and that may be affecting the body image ideals of young boys. The shape of the action figures' bodies had changed enormously over the decades. The action figures of the twenties century sport much bigger shoulders and upper bodies than those of the asses and asses. One study revealed that college age men wanted to add an average of 30 lbs. Of muscle to their bodies because they felt it would make them more at tractive.Even thou GHz to most of those men, that goal is unreachable for their body type. For both women and men, t he more they look at unrealistic portrayals Of the human body, the lower their self esteem and the I rower their self 2 Christiansen esteem, the higher their chances of developing an eating disorder, depression , anxiety or other mental illnesses. Today's young girls are bombarded by overly thin body image sees increasing their anxiety over living up to the â€Å"ideal† body image. An Australian study found that t both sexes had similar body satisfaction levels until age thirteen.After this age, the satisfaction n rate of both sexes drops. By the time they are nineteen, males begin to feel more satisfied again, eventually surpassing their earlier adolescent score. Females, while improving, never gag in reach the distraction level they had as children. Can this all be blamed on the media? A after all, it is likely that most young Women have natural, reasonable f ears about adulthood, esp. Cecilia issues such as childbirth and aging. Does anyone really fear aging because most models are young, or do people fear it because aging leads to infirmity?The â€Å"ideal† image portrayed for a woman's body is elongated and slender, wit h large breasts. Men are considered attractive when they are tall and muscular, with argue shoulders and a narrow waist. The problem of body image and the media is not restricted in N Roth America. One duty, conducted with 1 00 Australian girls aged nine through twelve, revealed that 49 percent wanted to be thinner, even though 85 percent of the girls who participated in the study were classified as being a healthy weight. So even girls who were perfectly healthy, still wanted to be thinner.When young girls want to be skinny more than they want to be health why, this should be a huge wakeup call for the world. However this has been going on for a while, a ND it still seems that there are significant changes in t he media and the world. Parents need to recur agonize their responsibility to serve as role models. In a ‘Glamour† magazine survey only 1 3 percent of 33,000 girls responded that their mothers were satisfied with their bodies. In addition n, many parents are allowing their extortionately daughters to get breast implants instead of coo ensiling or therapy to 3 Christiansen address self esteem issues.Unfortunately, positive parental comments often are disregarded while negative remarks can be intensely internalized. While this may have terrible e effects on a teenager's body image, but it can hardly be blamed on the media. Did you know that 95% of people who diet instead of following a healthy meal Lana will gain back the weight they lose in between one and five years. 73% of teenage girls who abuse diet pills and 79% of teenage girls who sulfured frequently read women's fitness and he lath magazines. /10 of girls who are high school juniors and seniors diet while on y 1/1 0 of high school girls are overweight. The twentieth century is when thinness has become me ideal. It most likely comes from woman competing with men for jobs. Either thinner women were seen as more masculine, and therefore better sued for muscularly jobs, or it might have bee n a backlash driven y men in the fashion industry to force women to refocus on their looks at the e expense oftener careers. Regardless, either scenario is denigrating. Despite these stereotypes, many larger women have become very highly successful.The majority of runway model meet the Body Mass Index (IBM) criteria to be c noninsured anorexic. At 5'7 and 95 lbs. Kate Moss is 30% below her ideal weight. Based on their theoretical boatyard percentages, most mannequins would cease to menstruate if they we re real women. Many actors and musicians have admitted to struggling with eating disorders including Deem Lavabo, Katie Court, Lady Gaga, Kate Backline's and Kelly Clarion. In Allure magazine model and actress Elizabeth Hurley stated, â€Å"I've always thought Marilyn Monroe look De fabulous, but I'd kill myself if was that fat. Some companies have made efforts to promote less unrealistic body images. Omega in the United Kingdom refused to run advertisements in â€Å"Vogue† magazine because the models appeared anorexic. Brazil has tried setting body mass mind ex (IBM) minimums 4 Christiansen for their models. Quebec magazine â€Å"Coup De Pouch† includes full size women , while â€Å"Chatelaine† o longer touches up photos and employs models only over the age of twenty five. Yet a certain amount of healthy criticism is still required.Dove has received a lot of favor blew press for their campaign to assign the â€Å"real† beauty moniker to wider ranges of women, but I including the word selfsame in their ads does not necessarily promote it. After all, they're still a appealingly consumers to buy their personal care products. Actresses Cameron Ditz, Julia Roberts and the singer Diana Ross meet the BMW I criteria for anorexia. When â€Å"New Women† magazine featured a filigreed model on t heir cover, readers overwhelmingly responded positively. Advertisers immediately threatened to pull their business, and benthic models were reinserted.After all, they couldn't sell products to consumers who are satisfied with their looks. Although it is true, it just goes to show you that co nannies don't truly care if the products works for you, they only need your money. It is important to remember the unreal ways women are shown in the media. This can help you to accept yourself and feel better about your body. One out Of 10 gig rolls and women develops disordered eating behaviors such as anorexia, or bulimia.

To increase the temperature of crude 2 step process is used; heat exchange with product streams & furnace. In the shell & tube type heat exchangers of Guwahati refinery Low temperature crude exchanges heat with high temperature streams of SRGO, RCO etc. in 3 stages(cold , mid, hot). The performance of some of these heat exchangers have a major impact on production and are classified as ‘Critical' on the basis of different criteria like frequent fouling, Large surface area.Calculation of heat duty, LMTD of some of these heat exchangers(s/15, S/23a-b,s-24) is done using design & practical data to check whether they are working efficiently as compared to design. Heat integration is an important concept to increase energy efficiency of process through heat recovery. Tools like pinch analysis are used in high energy demanding units like CDU to optimize the Heat Exchanger Network for maximum efficiency. Analy sis of past heat integration done in Pre heat train of CDU is taken as an example for analysis.

The report is based on Work in CDU of Guwahati refinery. Crude distillation units are used for the fractionation of crude into more valuable products using their difference in boiling points. Increase in temp for distillation us achieved in 2 steps; first step is the heat exchange of crude with product streams at high temperatures. In the next step a furnace is used to further elevate the temperature.Our main point of discussion in this report is the first step of heat exchange called the Pre-heat train. The pre-heat train consists of 3 sections: Cold, Mid & hot. The purpose of each section is t o recover heat from hot product stream of RCO, SRGO etc and supply it to crude through a shell-tube type heat exchanger. The details about various heat exchanger used in process are presented in the report. Performance of some heat exchanger is more critical on overall heat exchange than others; these heat exchangers are classified as ‘Critical heat exchangers'. Constant monitoring of efficiency of these heat exchangers needs to be done.As Example calculations like heat duty, LMTD is done in this report for some of these critical heat exchangers (S-11C, S-23A/B) to check their efficiency. Crude distillation is an energy intensive process. With increasing oil costs, the focus is to maximize energy recovery. One way to do this is ‘heat integration' which is a technique to design a process to minimise energy consumption. Tools like pinch analysis are used for obtain an optimized heat exchanger network for heat integration in CDU.

It’s called the ‘Mother unit’ as its products forms the feed of other units. CDU receives its crude from OM (oil movement and supply section) where it is supplied by Oil India Ltd from upper Assam oil fields. Incoming crude has following properties (2. 1 . 1): PropertyDensity at 15 oC Water content Salt content(ppm) Sulphur content(ppm) Value 0. 8735 2. 05% 8. 7 0. 29 CDU then stripes the crude into various products like kero1, kero2, reduced crude oil, LPG, heavy gasoline and light gasoline using the distillation principle of difference in boiling points. KEY FACTS ? ? ? Installed in 1962. Revamped and modernized in 1986 & 2000.

Crude is gaining heat in these exchangers from pre fractionated overhead vapours(in s-26), RCO( in s-29), SR Kero1 etc. Birla Institute of Technology & Science Pilani 333031 11 2. Desalter: Demulsifier mixed crud e is fed at 130 o C to Desalter (v-101) where it is mixed with water through a mixing valve. The salt in crude dissolves in water and separated from the oil. Salt free crude on the other hand is pumped to Pre-topping column (CL-1) though 2 safety valves. 3.Pre-topping Column (CL-1): The average temperature of crude before entering pretopping column is 238 oC (achieved through heat exchange). The purpose of this column is to remove the straight run (SR) light gasoline and LPG from overhead and reduce the load on the main fractionating column. Shown below is the Flow diagram of CDU(2. 1. 1): 4. Atmospheric furnace (C 1 A): the crude coming from CL-1 bottom at 246 oC is fed to furnace. Furnace is fired by fuel oil (FO), Fuel gas (FG) or a mix of both supplied by DCU. The crude coming out of the furnace has a temperature of around 354 oC and goes to the flash zone of main fractionators’ column. 5.Main Fractionators column (CL-2): It’s the most important part of CDU. Cl-2 i s where the actual distillation is taking place crude is separated into different products of different cut. Stripping stream enters at the bottom. The various subsystems of CL-1 are: Birla Institute of Technology & Science Pilani 333031 12 a) Overhead system: The overhead of the column of the water and the Straight rum Heavy Gasoline (SRHG) are separated. b) Stripper column: A stripping column (CL-3) is attached to the main fractionating column . Its function is to strip apart (separate) kero1, kero 2 and straight run gas oil coming from main fractionating column. ) CL-2 Bottom Section: The remaining crude oil called as the reduced crude oil (RCO) comes out of the bottom of CL-2. RCO forms the feed of DCU 6. Light Gasoline /Heavy Gasoline Processing System: Un-stabilized light gasoline from CDU pre-toping column is stabilized in the stabilizer where LPG is recovered from it while heavy gasoline is split in the two naphtha splitter to separate LN (Light Naphtha), RN (Reformer Naphth a) and HN (Heavy Naphtha). The table below shows properties of the Products formed in the CDU(2. 1. 2): LN TBP cut HN Kero 1 Kero 2 SRGO RCO 65-135 135-165 165-190 190-300 300-370 370+ 11. 27 4. 90 8. 16 12. 11 22. 16 9. 7 0. 731 0. 786 0. 806 0. 866 0. 866 0. 9542 range Yield (% of crude) Density Birla Institute of Technology & Science Pilani 333031 13 CDU PRE-HEAT TRAIN (HEAT EXCHANGE IN CDU) Birla Institute of Technology & Science Pilani 333031 14 3. 1 INTRODUCTION As we have seen the temperature of the Crude oil needs to increase to 354 oC in CDU. This section is a discussion on how this is achieved. Why Crude needs to be heated in CDU? The various components of crude oil have different sizes, weights and boiling temperatures. Crude Distillation Unit is used to strip this crude into various products using the difference in their boiling points.Therefore for distillation to take place the temperature of the Crude has to be elevated to around 354 oC so that all the fractions of cr ude oil can vaporize and get separated. How Temperature of Crude is increased in CDU? The Temperature increase of Crude oil consists of 2 major steps: 1. A 3 Stage Heat exchange (called CDU pre-heat train) of crude with product streams at high temperatures using shell & tube type heat exchangers. This step results in crude being supplied at 246 oC (elevated from ambient) to the next step ‘The atmospheric Furnace’. 2. The atmospheric furnace (C-1A) is then used to further elevate the temperature.Modes of heat transfer in furnace are both convective and radiative the crude coming out of the furnace has a temperature of around 354 oC and goes to the flash zone of main distillation column (CL-2). Furnace alone is not used because it would to too expensive and Energy consuming. By exchanging heat with products, the pre-heat train is serving twin purpose; The Crude is being heated at the same the temperatures of product streams of SRGO, RCO, KERO is brought down which was nee ded for their storage. This heat would have otherwise been wasted. Our point of discussion in this report is the First step i. e. The Heat exchanger Network’ which we will now study in detail. Birla Institute of Technology & Science Pilani 333031 15 3. 2 SHELL & TUBE HEAT EXCHANGER The Pre heat train uses shell & tube type heat exchager for heat transfer. ? It consist of two main things as its name implies Shell & Tubes ? The shell is a large vessel with a number of tubes inside it. ? The principle of operation: Two fluids of different temperatures are brought into close contact but they are not mixing with each other. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids.The temperature of the two fluids will tend to equalize. The heat is simply exchanged from one fluid to the other and vice versa. No energy is added or removed. Common types of shell and tube exchangers: Birla Institute of Technol ogy & Science Pilani 333031 16 3. 3 PRE-HEAT TRAIN: Description Our point of discussion in this report is first step of the 2 stages used for raising the temperature of crude i. e. the Heat exchanger network in which heat transfer occurs between crude and product streams of RCO, SRGO, and Kero 1. This network is also called the CDU pre-heat train.In this process the temperature of the crude is elevated form ambient conditions at which it is supplied from OM to 246oC. The heat needed for this is coming from the product streams which are at high temperatures. Dual purpose is served in this way: heating of crude as well as the cooling of product streams (needed for their storage). The pre-heat train is divided into three sections on the basis of temperature of crude flowing through them: 1. COLD section 2. MID section 3. HOT Section Shown below is the flow diagram of the CDU pre heat train (3. 3. 1): Birla Institute of Technology & Science Pilani 333031 17 1.Cold Section (before Desalt er): The crude from battery limit is pumped by pumps P-1/1A at about 15. 8 Kg/cm2 through a preheat train where it is heated to a temperature of 130 ? C before entering the Desalter (V-101). The following table shows the shell side & tube side streams of all exchanger in this section along with their inlet-outlet temperatures (3. 3. 2):Exchanger Service Shell Tube Total Surface area Heat Duty Temperature shell tube I O I O S-26 Gasoline Crude 300 x 1 2. 11 107 90 40 65 S-29 RCO Crude 171 x 1 0. 47 116 100 54 60. 3 S-12A Crude Kero 2 148 x 1 0. 92 60. 3 72. 6 130 82 S-27A/B Crude SRGO 183 x 2 1. 39 72. 5 0. 3 173 85 S-7 Kero 2 Crude 93 x1 1. 48 199 130 90. 3 109 S-11A/B RCO Crude 134 x 3 1. 49 165 115 109 122 2.

C. While the crude in Birla Institute of Technology & SciencePilani 333031 18 train B is preheated by SR kero circulating Reflux (CR) (in S-4A/B, S-12B) and RCO (in S-25A/B) to about 240 ? C. Desalted crude from both Train A and Train B streams are combined before entering the pre-topping column. Mixed preheat temperature achievable is around 238 ?

Problem or inefficiency in any of the critical exchanger has a severe effect on overall heat exchange process occurring in the crude distillation unit. The engineers need to see that these exchangers are working efficiently for smooth running of the process (Though efficiency monitoring is important for every exchanger but the most attention has to be paid for Critical heat exchangers).Criteria for Classification: 1. Fouling: is accumulation of unwanted material of heat exchanger surface is called fouling. Fouling is inevitable in heat exchanger but certain heat exchangers are more prone to fouling than others. The se exchangers foul in short intervals and need to be cleaned frequently. Their regular maintenance is very necessary for the heat exchange process. E. g. is S-11/C in hot section is prone to frequent fouling. 2. Large surface area: Some heat exchanger have a very large heat transfer area which means they have a large contribution in total heat exchange taking place.Their inefficiency or by-passing them would have a vital effect of final crude temperature. For example S-23 A/B in the mid section of heat exchanger trains. 3. Single heat exchanger in line: If a heat exchanger is single heat exchanger in the line like the one used in circulating reflux then it cannot be stopped or by-passed. For any maintenance work on them the whole unit has to shut down. Example is S16/9D. In next section the basic performance measurement calculations like heat, Duty, LMTD, Heat transfer coefficient is done for some of these critical heat exchangers.

With the rising costs of input like crude, power the process has to be designed to have maximum energy recovery so as to reduce the costs. Heat integration is one of the ways to achieve this. 1. MEANING Heat integration is technique for designing a process to minimise energy consumption and maximise heat recovery.Its part of the broader term ‘Process integration’ which is a holistic approach to process design which emphasizes the unity of the process and considers the interactions between different unit operations from the outset, rather than optimising them separately. 2. NEED FOR HEAT INTEGRATION Heat integration can lead to substantial reduction in the energy requirements of a process thus saving costs. It’s the answer to following questions: ? Are the existing processes as energy efficient as they should be? ? What changes can be made to increase energy efficiency without incurring any costs? What is the most important utility mix for the process? What investments can be made to increase energy efficiency? ? How to put energy efficiency & other targets like emission reduction, increasing plant capacity into one coherent strategic plan? 3. TOOLS FOR HEAT INTEGRATION ? Pinch Analysis The term pinch technology was introduced by Linnhoff to represent a set of the rmodynamics based tools that that guarantee minimum energy levels in design of heat exchanger networks. Pinch Technology provides a systematic methodology for energy saving in processes & total sites. Its prime objective is to provide energy saving by better process heat integration. Here are some of its key features:Birla Institute of Technology & Science Pilani 333031 30 1. Based on the first and second law of thermodynamics. 2. Pinch analysis is applicable for both new design as well as the retrofit systems. 3. It was developed for crude distillation systems but is now applicable to large number of process industries. 4. In addition to energy conservation Pinch technology provides general improvements 5. Some famous Pinch softwares are Pinch ExpressTM, Aspen PinchTM & SuperTargetTM ? Retrofit analysis Retrofit analysis is done to in old process processes to see what modifications suggested by pinch analysis are most suitable for the project.It looks into the optimization of the p rocess through energy capital trade off. In oil refining, retrofit designs are far more common than grass root applications. The retrofit targets are preferably achieved by re-using existing equipment more efficiently rather than installing new equipments and incurring new costs. 4. STEPS IN HEAT INTEGRATION Shown below are the different steps of heat integration (5. 1. 1) Birla Institute of Technology & Science Pilani 333031 31 5. 2 HEAT INTEGRATION IN CDU 1. IMPORTANCE OF HEAT INTEGRATION IN CDU Distillation is the largest single energy consumer in the Refinery.Large section of oil is spent in fuelling the CDU itself. It is energy intensive process as the temperature of the crude has to be elevated to a high temperature of 354 oC. This increase in temperature is achieved by exchanging heat in various heat exchangers between crude and streams of RCO, SR Gasoline, Kero 2 etc which are at high temperature. Heat integration focuses on achieving maximum energy recovery from these strea ms through an optimized HEN so that the crude can be supplied at highest possible temperature to the furnace, thus saving energy.A recent development in distillation technology has shown potential savings of up to 15-40 % through the heat? integrated exchanger network (pre-heat train) & distillation column. 2. HEAT INTEGRATION AT CDU GUWAHTI REFINEY What has been done? 1. The basis of heat integration in heat exchange process is putting process hot streams in thermal contact with process cold streams. We have already seen how product hot streams of RCO, SRGO etc at high temperature are used to exchange heat with the crude oil at low temperature. 2.Designing of an Optimized Heat Exchanger Network in pre-heat train using heat integration tools like pinch analysis & retrofit analysis in July 2010. This design allows maximum energy heat recovery. What can be done? 1. Using heat integrated distillation columns. HIDC can save energy by recovering excess heat from the rectifying section fo r usage in the stripping section. Birla Institute of Technology & Science Pilani 333031 32 2. Seeing the interactions of HEN and distillation column and applying combined heat integration for whole unit.

Research Paper Puerto Rico

Juan David Vivas Professor Holt ENC – 1102 Honors English Final Research Paper La ficcion y la realidad en Seva â€Å"Seva: History of the first U. S. invasion of the island of Puerto Rico that took place in May 1898,† is a story written by Dr. Luis Lopez Nieves that defies the boundaries of truth and fiction. This story was published on December 23, 1983 in the supplement of the newspaper â€Å"Red Clarity†. A story that was able to leave a legacy behind. This legacy created an atmosphere of questions and answers among the people in the island.The devastation that puertorricans felt over the words they were reading were caused by a simple proofreading error, arose much confusion where people were desperate for answers, and the perfection of how Seva was written made it impossible to be questioned. Before I continue on informing about this dreadful story, it is important that I state several historical facts in order to accept the authors full credentials and obt ain a better grasp of the story. Luis Lopez Nieves was born on January 17, 1950 in Washington, DC, from Puerto Rican parents.As early as seven years old he moved to the capital of Puerto Rico and at fifteen years of age began his studies at the University of Puerto Rico, Rio Piedras campus. The most luxurious university to study at that time. During his second year he was in Greenwich Village, an artistic and bohemian neighborhood of New York (Ciudsv. com/Datos). At twenty years of age he returned to the University of Puerto Rico and in 1973 graduated with a degree in general studies with concentrations in Comparative Literature and Hispanic Studies.Then he moved to the University of New York at Stony Brook, where he began his Master's degree in Hispanic Studies with a grant from the Ford Foundation. In 1980 he received a doctorate in Philosophy specializing in Comparative Literature and sets a precedent by being the first student to deliver a novel as a doctoral thesis: The Prince Alexander excessive happiness. Lopez Nieves is the author of the novels The Silence of Galileo, published in June 2009 and The heart of Voltaire, published in December 2005 (Ciudsv. om/Datos). This writer is also known for his excellent work as a storyteller with his books of short stories entitled The real death of Juan Ponce de Leon, published in April 2000, Writing for Rafa, published in 1987 and Seva. The week this story was published, the people of Puerto Rico were shocked to learn that the first U. S. invasion of Puerto Rico did not occur July 25, 1898 by the town of Guanica but that it happened on May 5th on the coast of the village that no longer exists called Seva (Ciudsv. com/Datos).That day, the 2,000 troops of General Nelson Miles was ambushed by 721 patriotic â€Å"savaenos† that resisted the American attack on the island and finally defeated the troops of General Miles. Actually it was not a historic victory but a great literary epic written by Luis Lopez Nieves (Ciudsv. com/Libros). A clarification that seemed to be absent on the published story of Seva in the newspaper Clarity caused much controversy in Puerto Rico since people were misled to believe the events occurred were true. The reaction was strong but confused. A harrowing mixture of joy, anger and pain.Joy because finally the old hated myth was destroyed of the alleged docility of puertorricans, their supine alleged delivery to the conquerors. At last, after many years of historical ignorance, puertorricans began to learn a few episodes of their true and heroic epic. Anger because such a vile act as the slaughter of Seva, and the total eradication of the people by the invaders, with good reason (Ciudsv. com/Libros). Pain because the people more courageous than ever, heroic even Lares, lay murdered, buried and forgotten under the planes, buildings and nuclear missiles of the naval base at Roosevelt Roads.After the Seva news, reports were confirmed that in Naguabo, Ceiba, Guayanill a, Rio Piedras, San Sebastian and several committees were organized within hours. The first committee was intended to find Don Ignacio Martinez, the only survivor of the slaughter of Seva: â€Å"My life has changed forever because last January 17 after 14 months of searching disheartened, I finally found the child-without-ear-left: Don Ignacio Martinez. When the Slaughter of Seva was 9 years old (and not 7 as I had estimated) and now has 92, but looks much younger. (Seva, 45)   Another committee was organized to dig in the Roosevelt Roads naval base at any cost until they found the remains of Seva, â€Å"The People Martyr†. In addition to the committees, a prominent psychologist met with the governor of Puerto Rico, Carlos Romero Barcelo, and demanded an investigation to give the whereabouts of Dr. Victor Cabanas. The Governor, given the facts, he was obliged to study the events. This reaction from readers and patriots is admirable, but there was a problem: Seva is a story , the result of a deep dissatisfaction with Luis Lopez Nieves history of Puerto Rico (Ciudsv. om/Datos). The newspaper Clarity, stunned by the events caused by the story he was obliged to publish an apology: â€Å"The text Seva: History of the first U. S. invasion of the island of Puerto Rico took place in May 1898, published in the last edition of In Red, is a story. The same has caused shock and alarm in parts of the country because it suggests a major historical discovery. While some read the text as a story, it seems that most of our readers thought it was a sensational historical article, the product of a thorough investigation and risky.But this is a story and nothing else but a story that became the product of imagination and the combination of literary resources of its author, Luis Lopez Nieves. † The immense controversy that caused Seva took the complete simplicity of just â€Å"another† column in the newspaper to have immediate government intervention to find answers. It rose over the whole story that threatens to take folkloric proportions. In sectors of intellectual, artistic, and academic independence of the country there was another issue this week. At parties, businesses, libraries and homes continually arose gatherings and discussions on the Slaughter of Seva.Attitudes towards the story begin in the euphoria (â€Å"Seva is a rallying cry,† says Ferdinand Quintana, Guayanilla musician). Several crosses appeared in front of the Roosevelt Roads naval base with the inscription: â€Å"Seva Lives! â€Å"(Seviv. com/criticas). The â€Å"Capitolio News Agency† (The white house of Puerto Rico) assigned the reporter Jennifer Wolfe to travel immediately to Washington with the intention of interviewing Peggy Ann Miles, the granddaughter of General Nelson Miles that received Dr. Victor Cabins with â€Å"biscuits, tea and very polite words†, a person that does not exist (Ciudsv. om/Datos). The poet Jose Manuel Torres Sant iago confirmed that following the clarification of the magazine Clarity to the effect that Seva was a story, many in Guayanilla and San Sebastian protested and refused to believe it was said then that Seva Editorial reality and fiction. Many refused to believe that Seva was a story and chose to stay with the version of Luis Lopez Nieves. A prominent nationalist claims to know a veterinarian who, in turn, had an uncle who spoke of Seva. â€Å"Its Ceiba,† the vet told his uncle. â€Å"No,† he replied, â€Å"I do not speak of Ceiba but of Seva†.This nationalist seemed very concerned and said that Seva is a reality. He resists, moreover, to believe that Don Ignacio Martinez is a fictitious entity created by Luis Lopez Nieves (Seva, p. 58). Fortunately, in the same way that people were wrong or did not understand the satire of Lopez Nieves, there were people who understood. A famous guayanillense wrote the following note with the real meaning of the story: â€Å"Sev a is for me a reality of all Puerto Ricans, regardless of political positions, that could happen or has happened in our town that is still suffering the same symptoms of the past.But as long as men determined as Seva, Puerto Rico will have a firm hope, of all Puerto Ricans who believe in the values that the country means for everyone. Although they do not deserve to have benefits and come to mourn for what they have not earned or deserved. But we are all too ‘Ay Bendito’ that we forgive him. † (January 9, 1984, Jose Eugenio Rivera Castagnet) The elaborate and well detailed of the context in Seva presented the story so well that it was extremely difficult to determine fact from fiction.For the first time an author was able to take a story that was not true but because of historical events, it seemed as if it had happened exactly as stated (Seviv. com/critocas). This work is extraordinary. This paper published by Luis Lopez Nieves is a hit. It is an invitation to de lve into the history of Puerto Rico, for Seva is not far from the truth. Among the readers of Clarity are probably the most sophisticated, better informed and more critical of the island: professors and university students, boxes on the left, lawyers, labor leaders, and professionals (Ciudsv. om/Libros). The author wanted to share with the people the truth that good fiction reveals: the truth about puertorricans. That is, it looks like people get an immediate sense of patriotism to see how a town was erased from history. Puerto Rican’s know the abuses that the American people rushed against Puerto Rico, the problem is that they forget or are given a blind eye when they give their coupons, housing and entertainment, among other things. They think that to swim against the current is comprehensive and to swim along is demeaning and insulting for the soul and freedom.So they are undecided and have a lifestyle like if nothing is happening around them (Ciudsv. com/Datos). We find r eality hard to believe and accept. The fiction on the other hand can easily be taken as true. How else can one explain that a publicity stunt by the author of Seva: The True Story of the American invasion in 1898 has caused such a stir, mostly clarifications and explanations from the area called the country's intelligence?
