Batch Reactor As A Plant Engineering Essay
Batch Reactor As A Plant Engineering Essay What is a plant unit. All Equipment that make up a plant can be divided into 3 different categories or levels, the highest being the Plant as a whole, then the plant units and the lowest are the plant items. While the actual plant performs an overall production, the Plant unit refers to the main components of a Plant which perform a major production function of the Plant and without which the Plant can not continue its operations. A Plant unit is made up of items but it can be replaced as a whole (Anthony Kellyà ¢Ã¢â ¬Ã ¦) In this Plant, the Batch Reactor receives raw materials from the raw material storage, processes them for a certain amount of time then transfers them to the centrifuge feed vessel. From the above diagram, it is obvious that the Batch Reactor is a major component of the plant and from its function it is seen that the reactor must process the raw material for progress to be made to the next stage of production. I am therefore concluding this as my explanation as to why the Batch reactor is a plant unit. Explain Your Reasons For Concluding That This Unit Is Critical For Production. Several Factors determine how critical a piece of equipment is to production. They include: Will the Equipment affect safety in the plant? Will the Equipment not working cause downtime in the plant? How easily can the Equipment be maintained? What is the cost of this maintenance? What is the current situation of the Equipment? (Paul Wheelhouse) Now each of the factors can be used to examine the Batch Reactor and after which an educated decision can be made. The Batch Reactor affects the safety in the plant because its function involves the heating of chemicals under pressure and its failure might cause the leakage of these chemicals or at the worst lead to an explosion in the Plant. If the Batch Reactor was to stop working, there would be prolonged downtime until it is fixed; this is due to the fact that the Reactor performs a major function in the Plant without which further production would come to a halt. The Batch Reactor is made up of a number of different items, some of which can be run-to-failure, but for the most an established schedule of maintenance must be made for. Without such a schedule, maintenance would be most difficult to carry out. The cost of maintaining the Batch Reactor may vary but if is not properly attended to; one fault might lead to another even bigger one so the cost of maintaining might increase. The items in the Batch Reactor have a life plan which is currently not being kept to; this means the Equipment requires monitoring to avoid random failure or prolonged breakdown and downtime. On the account of the above facts, it is my belief that the Batch Reactor needs to be labelled as critical. Extract Any User Requirements For This Designated Unit From The Plant Description. Are There Any Production Windows? What are User requirements? This simply refers to the specifications that are inbuilt in a piece of equipment so that it might be able to fulfil the end users needs according to those tasks which it is used to perform. In line with the plant description given on this particular Batch Reactor, a number of user requirements can be ascertained and these are listed below: To receive 18te of raw materials from the raw material storage. To remain sealed and heat its contents through a preset temperature / time profile by use of a temperature control system consisting of a thermocouple in a temperature pocket, a temperature controller and a control valve. That the control valve regulates the supply of low pressure steam. That its temperature alarm signal when the temperature exceeds 1250C. That all safety relief valves work in event of an increase of temperature past the safety limit of 1250C. That the bottom run off valve opens when the operation is complete and releases the contents from the Batch reactor to the centrifuge feed vessel by the discharge pump. That the operation lasts 10 hours only. What is a production window? This is a period during production in which maintenance procedures can be carried out without causing a halt in production. With emphasis on the Batch reactor it can be seen that there is a production window and this can be explained below. While the batch reactor makes 18te of product every 10 hours, the centrifuge processes this product at a rate of 1.5te an hour i.e. it would have completely used up the 18te of product in 12 hours. Since it takes 10 hours for the batch reactor to work, this would give a 2 hour production window in which it can be properly maintained. Also depending on the capacity of the centrifuge storage vessel, it is possible for the batch reactor to work overtime filling this feed vessel up and then be switched off and maintained while the centrifuge is operated using the previously stored produce in the centrifuge feed vessel. Extract Any Corporate Requirements for This Unit From The Plant Description. What are corporate requirements? These are the requirements which the upper management or Business sector of the company running plant desire from its industrial operations in order to make a suitable return on its investments (ROI). From the plant description the following corporate requirements can be made below: That its keeps to its scheduled annual shutdown period of 16 hours during week 40 each year. That all maintenance pertaining to the batch reactor abides by the permit to work system which controls all maintenance activities. That the batch reactor achieves a 25 year life and that the gearboxes achieve a 15 year life as well. That the batch reactor remains well-painted, clean and tidy at all times. Extract Any Legislative Requirements for This Unit From The Plant Description. What are legislative requirements? These are Plant requirements made by the Law, rules or regulations or the Country in which the Plant operates. They must be implemented in order for the plant to avoid sanctions or being shut down. In this particular plant description they include: That the Batch Reactor abides by the rules by the FDA and British pharmaceutical Society put in place for their license holders. All production and maintenance activities involving the Batch reactor comply with the Good Manufacturing practise (GMP). That the processes involving the Batch Reactor are as okayed by the quality standard ISO 9002. That the batch reactor conforms to the environmental standard ISO14000. That if used by the Pharmaceutical inspection team, the batch reactor must pass any risk-based inspections based on a DNV methodology that might be carried out. Comment On If Some of The tasks Designed For Shutdown Could be Done During Production Windows Or When The Plant Is Online. Could Any Of These Tasks Be Designated For Completion During Production Windows Be Completed Online? We have previous explained what production windows are and when a Plant is online refers to when the plant is carrying its usual operational procedures. From the work done previously in section 1.3, we now know that there is a definite 2 hour production window during which the batch reactor can be maintained while the centrifuge is working. In looking at the life plan for the batch reactor unit, there are a certain amount of tasks that could be done in 2 hours and should be moved from shut down to production window, these are: The replacement of the trim of the CV1 every 2 years. The pressure testing and inspection of the SV1 every 6 years. The visual check of the Agitator every 6 years. The SV2 pressure testing and inspection every 6 years. There is only one task put to be completed when there is a production window and it can be done while the Plant is online. This is the weekly visual check on the Agitator coupling, because if it is checked while online it might lead to the location of which wouldnt have being seen if the equipment was offline. Analyse The Recorded Jobs From The Computer Maintenance Management System (CMMS) For This Unit. Is There Any Evidence Which Confirms That The Life Plan Is Being Carried out? Is There Any Evidence To Say If The Life Plan Is Effective Or Not? What is a Life plan? All plant units or manufacturing stages in production are designed to have a certain life. To fulfil this, maintenance plans are put in place to achieve this expected equipment life and if possible, to exceed it. These maintenance plans are called Life plans. (Wheelhouse, 2008) On comparing the life plan of the batch reactor to the computer maintenance management system (CMMS) it can be seen that the life plan isnt being carried out. This is due to the factor that there is a remarkable difference between the standard time taken to maintain every single unit item in the reactor and the actual time the job was done in hours, meaning the maintenance done cannot be adequately planned for and could lead to excessive downtime. It can be seen that for this singular reason the life plan of the batch reactor is not capable of being effective. Use The Figures, Plant Description And The Data From The CMMS To Analyse The Unit Into Its Maintenance Causing Items. Using the figure 1 shown previously and the figure 2 shown directly above as well as the Life plan and the CMMS, the maintenance causing items can be broken down as done bel Batch Chemical Reactor CV1 Agitator Coupling Temperature controller Gearbox Motor bearing Oil seal Agitator Trim Agitator gear box Reactor Vessel Temperature sensor Pump Motor Pump bearing SV1 SV2 P1 V1 Vessel Jacket Figure 3: The Maintenance Causing Items in a Batch Chemical Reactor Develop your own life plan for these maintenance causing items using the task selection logic for Reliability Centred Maintenance.

Compare and contrast between your Life plan with the one described previously, comment on any similarities and differences. There are a number of ways in which my Life plan differs from the one previously given but there are also ways in which both are similar. Some of them are as listed below: To begin, the first detail that can be noticed when comparing both life plans is that since I used the RCM selection logic, my life plan carries much more details as I included the functions, functional failures, failure modes, failure effect and criticality of each subsystem or item. This will be particularly useful in settling up priorities as the criticality of each subsystem is set at low, medium or high depending on the considerations of safety, performance and impact of the subsystem or item on the rest of the plant. I brainstormed and added more failure modes and their activities than had being previously discovered or had activities planned for in the previous life plan so as to further prepare maintenance personnel to be able to tackle these failures if and when they do occur. I changed the time frame for certain activities to take into consideration the new 2 hour production window that was discovered earlier. This will help reduce the amount tasks that are done during a shutdown and therefore cut down the downtime which the plant undergoes. I increased the amount of time to be used to accomplish most tasks due to the fact that in the previous life plan, insufficient time was allocated to these tasks so therefore they couldnt be planned or executed properly within the targets set for them. Now in terms of similarities, I observed that the preventive maintenance and condition monitoring carried out on the Batch Reactor had ensured breakdowns were kept to a minimum so bearing this in mind, I retained all the activities from the old life plan and continued using them for the various items. I also continued to carry out maintenance activities at the same frequency that was mapped out in the old life plan as I believe that the punctuality with which activities were carried out improved the reliability of the equipment. CHAPTER 2 Describe The Philosophy of Total Productive Maintenance. What is TPM? Total Productive Maintenance (TPM) refers to a management system for optimizing the productivity of manufacturing equipment through systematic equipment maintenance involving employees at all levels.à Under TPM, everyone is involved in keeping the equipment in good working order to minimize production losses from equipment repairs, assists, set-ups, and the like. (http://www.siliconfareast.com/tpm.htm). The goal of TPM is to increase production while at the same time boosting employee morale and job satisfaction. (Venkatesh. J) This is possible because there would be less downtime as TPM is carried out by the Operators on the items or machinery which they use as they, the maintainers and Designers work as a team towards the total elimination of equipment defects in the Plant (Paul Wheelhouse). History of TPM TPM is a Japanese idea that can be traced back to 1951 when preventive maintenance was introduced into Japan from the USA. Nippondenso, part of Toyota, was the first company in Japan to introduce plant wide preventive maintenance in 1960. In preventive maintenance operators produced goods using machines and the maintenance group was dedicated to the work of maintaining those machines. However with the high level of automation of Nippondenso, maintenance became a problem as so many more maintenance personnel were now required. So the management decided that the routine maintenance of equipment would now be carried out by the operators themselves. This is known as Autonomous maintenance, one of the features of TPM. The maintenance group then focussed only on maintenance works for upgrades. For pioneering TPM, Nippondenso became the 1st company to receive TPM certification (wikipedia). Why Use TPM? For TPM to be used in an Organisation, everyone from senior management to the operators on the floor must be carried along and made to understand why this particular system is being used. For this to happen effectively, the Motives, Objectives and benefits must be fully stated out and properly absorbed. The table below gives a generic illustration: Motives of TPM Adoption of life cycle approach for improving the overall performance of production equipment. Improving productivity by highly motivated workers which is achieved by job enlargement. The use of voluntary small group activities for identifying the cause of failure, possible plant and equipment modifications. Uniqueness of TPM The major difference between TPM and other concepts is that the operators are also made to involve in the maintenance process. The concept of I (Production operators) Operate, You (Maintenance department) fix is not followed. TPM Objectives Achieve Zero Defects, Zero Breakdown and Zero accidents in all functional areas of the organization. Involve people in all levels of organization. Form different teams to reduce defects and Self Maintenance. Direct benefits of TPM Increase productivity and OPE (Overall Plant Efficiency ) by 1.5 or 2 times. Rectify customer complaints. Reduce the manufacturing cost by 30%. Satisfy the customers needs by 100 % (Delivering the right quantity at the right time, in the required quality.) Reduce accidents. Follow pollution control measures. Indirect benefits of TPM Higher confidence level among the employees. Keep the work place clean, neat and attractive. Favourable change in the attitude of the operators. Achieve goals by working as team. Horizontal deployment of a new concept in all areas of the organization. Share knowledge and experience. The workers get a feeling of owning the machine. Figure 4 .TPM table Source: An Introduction to Total Productive Maintenance (Venkatesh. J) For TPM to start properly, the OEE (Overall Equipment Effectiveness) should be calculated and a loss analysis performed to give both a baseline for continuous upgrading and ascertain the improvement priorities. This will allow the operator/core maintenance team to prioritize and then tackle the 6 classic losses of: Breakdowns Set-ups and changeovers Running at reduced speeds Minor stops and idling Quality defects, scrap, yield and rework Starting up losses The above losses add to the direct costs. Implementation of TPM attacks these and other direct (visible) costs as well as indirect (hidden) costs and follows each step in the production and supply chain from Management to the human resources to the Machine to the process, then to suppliers and finally to the customers (Willmott and McCarthy). Components of TPM Figure 4: Pillars of TPM Source: An Introduction to Total Productive Maintenance (Venkatesh. J) As shown above, TPM is made up of 8 main aspects which when combined present the full TPM package. They are: The 5 S which are primarily the foundation of TPM and involve organising the workplace. These are sorting, systematising, sweeping, standardising and self-discipline. Autonomous maintenance which refers to the operators handling most or in cases all of the maintenance concerning the machines which they operate. Kobetsu Kaizen means small improvements or changes for the better of the organisation. Planned maintenance entails scheduled maintenance which is done to ensure trouble free machines and equipments producing defect free products for total customer satisfaction. Quality maintenance is aimed at providing customer satisfaction by providing the highest quality through defect free manufacturing. Training to give employees a multi skilled edge. Office TPM to ensure administrative efficiency as well. Safety, health and environmental awareness to ensure zero accidents, zero health damages and zero fires (Venkatesh. J). Describe a Case Study Where TPM has been successfully applied The case study which I wish to use is that of RHP Bearings. This RHP Bearings branch which is in Blackburn, manufactures cast iron bearing housings for a variety of uses from agricultural machinery to fairground rides, and is one of seven RHP manufacturing sites in Europe owned by Japanese group NSK, the worlds second largest bearings manufacturer. How TPM was carried out. NSK acquired RHP in 1990, when the Blackburn site was under the imminent threat of closure because of high costs and the subsequent lack of competitiveness. Employing a staff of 93, TPM was then introduced to the site in 1993 but it didnt see much success till 1996 due to the fact that the earlier efforts to drive TPM had been largely theoretical and the workforce faded to see its relevance to the everyday running of the plant. In 1996 a maintenance company was brought in to do a scoping study of the plant, conduct a workshop and support two pilot TPM projects. The Plant Manager and the TPM facilitator then began to implement measures to ensure TPM was made directly relevant to the jobs of the staff. Operators were sent off to climb over their machines and log problems through a detailed condition appraisal, to establish a foundation for future TPM improvements. TPM was piloted on two key machines, the PGM core making machine in the foundry and the Shiftnal sphering machine in the machine shop, using a detailed seven-step TPM implementation programme: Collection and calculation of Overall Equipment Effectiveness (OEE) Data Assessing the six losses Criticality assessment and condition appraisal Risk assessment Refurbishment plan Asset care and best practice routines Regular review for problem solving TPM is applied to machines of all ages from new to 30 years old, ensuring that older machinery is brought up to modern specification and newer machinery is kept in as-new condition. The TPM was applied at the site by 9 different equipment teams focusing on specific machinery and involving 60% of the workforce. These teams included operators, maintainers, quality technicians and group leaders also drawing on help from personnel with specialist skills when necessary. Each Team developed a standard routine for their respective machines using: Autonomous Maintenance System (AMS) boards which show a schematic of the machine then tags with labels to show losses affecting availability, performance and quality. These labels are then used to generate TPM agendas for team meetings. TPM step notices which illustrate the machines progress in TPM seven step programme. Mainpac database which is used to gather machine performance details and calculate the OEE. Key performance indicators which the teams use to accesses their improvement and progress in areas of waste sand, Gas emissions, Kaizen, Customer returns, lost time incidents, injurious accidents, Audit and product conformance. Each team then has an activity board covering subjects such as milestone activities and previous days conformance result among others. To ensure TPM succeeded, Teams had to dedicate substantial time to carrying out laid down activities and held meetings as needed. Benefits of TPM Implementing TPM had both direct and indirect effect on the production system a combination of which generated major savings at RHP, Blackburn. Major Site-wide benefits were scored in the following areas: à ¢Ã¢â¬Å¡Ã ¬400,000 running costs saved Unit cost reduced by 21% Scrap reduced by 8% Attracting increased capital investment currently at 15% of turnover and Customer returns reduced by 11% Increased customer satisfaction Improved safety record Environmental and quality awards Improvement in staff morale The two key machines (The Shiftnal sphering and the PGM core making machine) also had major total cost saving OEE improvements as well as other time saving and cost reduction achievements making the TPM well worth it (Willmott and McCarthy). Reliability Centred Maintenance (RCM) As Applied in a Section of a Plant What is RCM? RCM is a method for developing and selecting maintenance alternatives based on safety, operational and economical criteria. RCM employs a system perspective in its analyses of system functions, failures of functions and prevention of these functions (Jones, R.B). So RCM requires in-depth of the machinery, detailing all logic problems and their maintenance solutions and as such can be quite time consuming, for this reason it is usually used only on the critical equipment. The use of RCM methodology requires that 7 questions be answered: What are the functions of the Asset? What are the functional failures? What causes the functional failures? What happens when the failure occurs? How much does each failure matter? Can we predict or prevent failure and should we be doing so? How should we manage the failure if prediction or prevention is not an option?(Paul Wheelhouse) Now in order to answer the above questions, a System analysis process is used to begin RCM on any section of the plant. This System process will implement several steps, all of which define and characterize RCM and will methodically delineate the information required for the maintenance: Step 1. System selection and Information collection: Taking decisions as to what level of the plant at which to do the RCM and also choosing this system or section based on criticality i.e. based on function and impact on plant and environment. Step 2. System Boundary Definition: This involves creating an accurate list of what is or is not part of the section so an accurate list of components can identified and to establish what comes in and what leaves the System(IN and OUT interfaces). This is necessary to ensure the accuracy of the Systems analysis process. Step 3. System description and functional Block diagram: This is used to identify and document the essential details of a system that are needed to perform the remaining steps in a thorough and technical fashion. The five separate items are developed in this step: System Description Functional Block Diagram IN/OUT interfaces System Component list Equipment history Step 4. System Functions and Functional failures: involves classifying each OUT interface of the system into its functions and identifying the failures which might hinder these functions. Step 5. Failure Mode and Effect analysis (FMEA): involves analyzing each component failure to discover which have the potential to disruption their function and then detailing what exactly these effects could be. This is done using functional failure-equipment matrix. Step 6. Logic (Decision) Tree Analysis (LTA): the failure modes which pass through effects analysis will now go through this process. The purpose of this step is to further prioritize the emphasis and resources that should be devoted to each failure mode on the basis that all Authority (TVA). TVA is a power production plant wholly owed by the US government and equipment, functions and failures are not the same. The LTA identifies the failure modes in 3 aspects: Safety Downtime Economics (Finance) Step 7. Task selection: In this step, applicable maintenance tasks which are most effective to combat the detailed failure modes are listed, at the same time decisions on whether to run-to-failure or design out

Burqas Should Not Be Banned
Religion and Society Article Assignment. Articles used ââ¬â 3A and 3B. The Burqa. Sylvie Maclean. A Burqa is an article of clothing that is generally considered as a religious statement. The Burqa consists of full robes and a mesh veil over the eyes. There are other options of robes that can be worn including the Hijab and the Niqab, where the eyes remain uncovered. According to come interpretations of the Islamic sacred text ââ¬â the Koran (Qurââ¬â¢an) ââ¬â women must wear a full veil in order to be modest. Many Muslims wear the Burqa because it is symbolises and is a part of their spiritual journey, so they wear it by choice.While others wear the Burqa because they believe they have to, as it is one of the commandments of god to dress modestly. There are many Muslims who choose not to wear the Burqa at all. They may opt for a simple headscarf and normal clothing; they also can wear the Hijab or Niqab. But then again there are many Muslims who choose to dress in norma l clothes, therefore bringing no attention to their religion. Not wearing the headscarf or robes does not make a person any more religious, nor does wearing the Burqa make someone more religious than another Muslim who is not wearing any religious clothing at all.Just through reading articles A and B, we see that there is a lot of controversy involved in this topic, and something I would like to address is how we have the right to tell others how to dress when their clothing choice brings no harm upon us and is a completely individual and personal choice. Image Source: http://www. hopeitw. com/knowledge/abaya-niqab-burqachadordupatta-hijab/#sthash. OXN8dy8O. dpbs Image Source: http://www. hopeitw. com/knowledge/abaya-niqab-burqachadordupatta-hijab/#sthash. OXN8dy8O. dpbs Throughout article A ââ¬ËWhy Iââ¬â¢m proud to wear the Burqaââ¬â¢ we see examples of the controversies over the banning in France.The author ââ¬â Oumkheyr ââ¬â is a Muslim woman who wears the full B urqa by choice, and is being strongly threatened by the French Government where a ban of Burqas may soon be implemented. Oumkheyr says ââ¬Å"I really believe that France is scared of Muslims, which is the motivation for this law, but people shouldn't generalize as not all Muslims are the same. Yes, some have done terrible things, but it is done in the name of man, never in the name of God. â⬠But, although in the Koran there are verses that say some hateful things like ââ¬Å"slay them wherever you catch themâ⬠(Quran 2:191), these quotes are taken completely out of context.The rest of that particular quote is as follows ââ¬Å"fight in the cause of God those who fight you, but do not transgress limits; for God loves not transgressors. And slay them wherever you catch them, and turn them out from where they have turned you out; for tumult and oppression are worse than slaughterâ⬠¦ But if they cease, God is Oft-forgiving, Most Mercifulâ⬠¦ If they cease, let there b e no hostility except to those who practice oppressionâ⬠(2:190-193). The Koran gives messages of hope, faith and peace.Itââ¬â¢s easy to take something out of context and quote it, but it means that what was originally being said loses all meaning. Linking back to the Burqa ban, maybe the French government would stop being so scared of muslims if someone actually bothered to read the full quote. Oumkheyr makes some very strong points in her article, that everyone should take into consideration when deciding their personal opinion of the Burqa ban proposal. The second article, ââ¬ËThe Burqa is a war on womenââ¬â¢ addresses the reasoning for a ban. The author ââ¬â Virginia Haussegger ââ¬â has successfully outlined the views of many non-muslims.Within the first two lines Ms Haussegger has already accused the Burqa of subjectifying women, and stated that the reason for wearing the Burqa is what ââ¬ËGod Demandsââ¬â¢. What the author doesnââ¬â¢t seem to real ise is that for the majority of muslims, wearing the Burqa is a personal choice, and most say they donââ¬â¢t think it is a ââ¬Ëdemandââ¬â¢ as such, but more of a way to become more in touch with god and the rest of their religion. Some Islamic tectsstate that women should dress modestly, but wearing the Burqa is the individualsââ¬â¢ decision, and it reflects on the individualsââ¬â¢ values and beliefs about the word ââ¬Ëmodestyââ¬â¢.This article brings up many points about equality. Saying that while ââ¬Ëmen roam free while women wear a sackcloth that dehumanises them. Although it is true that Muslim men do not walk around shrouded head to toe, this is for a reason that Haussegger seems to have forgotten: womenââ¬â¢s bodies are constantly being subjectified and having their bodies sexualized, and men are not. Although this is not necersarily the ââ¬Ëpolitically correctââ¬â¢ thing to say, it is the truth, and wearing the Burqa is a way for this to stop .The author does have some very valid points on the subject of actual legitimacy of the commandment about the Burqa, but even if the Koran does not state ââ¬ËWomen must cover their face and bodies to hide from public viewââ¬â¢, the Burqa, Hijab, and Niqab are just clothes. By reading these articles it is clear to see that both authors are fighting for the rights of Muslim women. Although Virginia Haussegger clearly believes that by wearing the Burqa women are being further objectified, both authors agree that what we wear is our choice and no one elses.Muslims live by their holy text and if the individual interprets its commandments to believe that to be a good muslim you must wear the burqa, then that it their choice, and freedom of choice is a human right that we should all have. What Haussegger sadly doesnââ¬â¢t appear to understand is that no matter how a Muslim chooses to dress, their beliefs are the same and they are living by the same god, so banning one article of c lothing cannot change how the individual will behave.My opinion on the Burqa is that although the outfit may be somewhat demeaning, it is a personal choice that I will never fully understand. Now that I have done further research into the topic I understand the choices and decisions that are made when the Burqa is concerned, and I am definitely more open to other peopleââ¬â¢s opinions. I think it is completely unreasonable for non-muslims to call a ban on the Burqa as it is a human right that we are free to express ourselves however we see fit, and if this is how some Muslims choose to express their religion, then good for them.Form| Title| URL| Date accessed| Article| Should Burqas Be Banned? | http://middleeast. about. com/u/ua/religionsectarianism/burqa-hijab-ban. htm| 14/03/2013| Book| Islam beliefs and teachings| Written by Ghulam Sarwar| 20/03/2013| Article| We too should ban the Burqa| http://www. telegraph. co. uk/comment/columnists/allison-pearson/8449101/We-too-should-b an-the-burka. html| 23/03/2013| Article| Europe must not ban the burka| http://www. guardian. co. uk/commentisfree/2010/mar/08/europe-ban-burqa-veil|

The Spread of the Plague - 1671 Words
The word plague means a dangerous disease that quickly spreads and causes death. Alexander Yersin identified the cause of the bubonic plague. He discovered that the disease was being caused by a deadly bacterium which he named after himself, Yersinia pestis. Yersin worked with a scientist named Pasteur in France to develop a treatment to fight the plague. Yersin was the first to suggest that rats and fleas were the main cause for the spreading of the plague. Symptoms of the plague emerge after one to seven days which include fever, swelling in the regional lymph nodes in the groin, armpit, or neck. In most cases the bacterium spread to the bloodstream and central nervous system resulting in death 100 percent of the time. There are actually three types of plague; the most common was the bubonic plague. ââ¬Å"The disease in humans has three clinical forms: bubonic pneumonic and septicemia. The Bubonic plague is the best known form in popular lore, and indeed it constitutes about three -fourths of plague casesâ⬠(Encyclopedia Britannica 3). The bubonic plague is the blame for causing the Black Death of the fourteenth century. The symptoms of the bubonic plague strike rapidly within two to five days of being bitten by a flea or rat. The first stage of symptoms includes; fever, chills, severe headache, sore throat, and muscle aches. The second stage of symptoms include; vomiting, diarrhea, seizures, and respiratory failure.

Existentialism In Being Zack Morris, By Chuck Klosterman
The article, ââ¬Å"Being Zack Morris,â⬠by Chuck Klosterman seeks to show how humans look at the world existentially through the show Saved by the Bell. Existentialism means affirming or implying the existence of a thing. Klosterman used Saved by the Bell to not only show how most of reality is not real but to show how humans interpret or apply their own meaning objectively. Saved by the Bell was a fictional show about high school students. ââ¬Å"The writers of Saved by the Bell always seemed to suggest that most adolescents are exactly the same and exist solely as props for the popular kids, which was probably true at most American high schools.â⬠(140) What happens when one looks at culture that is ultimately not real as being representative ofâ⬠¦show more contentâ⬠¦Ã¢â¬Å"Youââ¬â¢d think Zackââ¬â¢s unconventional relationship with an authority figure would be the least of Joelââ¬â¢s concerns.â⬠(141) Surprisingly it was his only ever complaint on a show where Zack could pause time and ââ¬Å"oil was discovered under the football teamââ¬â¢s goalpost.â⬠(141) The intriguing part of Joel and humans as a whole is not having an aesthetic perspective every once in a while; but, rather his distinction between what seems real and what is not.

What the student would expect (i.e. stereotypical ending) the show would perform. The episode where the cast goes to a party and Zack decides to drink and drive is an example of this. ââ¬Å"If these kids drink and drive, they will have to have a bad accident- but no one will actually die, because we all deserve a second chance.â⬠(143) NBCââ¬â¢s purpose of this episode was to teach kids to not drink and drive. Existentially, students took it as you can drink and drive and only face minor consequences. After all, all the members of the cast survived. ââ¬Å"People tend to be more impressed by the packaging of the jewel case than the songs themselves, and they end up
