Baxter Manufacturing Essay Example for Free

Baxter Manufacturing Essay Baxter Manufacturing Company (BMC) is a metal stampings company. Its major customers include, Ford, General Motors, Honda of America, General Electric and Whirlpool. The company is made up of two divisions it makes brackets and other components that go into the finished product, they also make motor casings. BMC employees about 420 non-union employees and has been steadily growing for the last 6 years. They have been approached to build a factory in Mexico, and settled on building in Queretaro, which is about a 3-hour drive north of Mexico City. Don Collins, who is the MIS manager, felt that since a new plant was being built with top of the line equipment and computer systems that they might be able to implement a system upgrade for the entire company. One of the problems was that BMC wanted the new system implemented by the end of the year. Given the quick deadline they decided to focus on support for the Mexico plant, a felt that the following approaches: 1. Connect the Mexican plant to BMC’s existing systems through a high-speed communications line   2.  Contract through an application service provider (ASP) to provide systems support to the Mexican plant. 3. Employ a piecemeal solution where they would acquire a number of software packages that could run on the networked PC’s in Mexico that would serve the basic needs of the Mexican plant. (MIS) The task force team ran into difficulties with language and cultural differences, the mindset of the employees and Mexico and the long distances between them. They met with resistance and self pride from the Mexican employees and were unable to communicate effectively with them. Target As a result of the lack of communication and the language differences the task force decided to go with option 3. They were working on locating vendors to provide support and with basic language software to help the employees stateside. The main issues that they are having are support for the systems and training for the equipment. By outsourcing some or all of ts IT work to a company that is familiar with the language and culture it could help expedite the time of getting the plant operational. In addition developing a training program that could be taught companywide could help benefit the entire company. Proposal One of the main issues that BMC is looking for is international support. They are been unable to work directly with its own employees due to the language barrier that it faces. By using a company like Unisys, they could provide the infrastructure support, business service support and many other features. They offer support in English and Spanish and could help ease the burden of the local IT department. Unisys could also implement a Cloud, in which the entire company could use to help transfer information to and from different locations. â€Å"Business forces have caused IT to try to figure out how to provide flexible services faster, but, without large, up front investments. Unisys has a number of cloud solutions for providing the necessary flexibility and responsiveness needed to achieve significant business value. † (Unisys) A great deal of time has gone into the development of this plant, but an equal or greater part must be present in training of the employees. In order for the plant to be fully operational at the level that is required by MBC, a training program must be designed. They would benefit greatly by having management train with how BMC currently runs its operation. By also setting up a video conferencing line they could help problem solve over the computer and or phone lines helping eliminate the distance between the two plants.

Anti-Semitism Essay -- Prejudice Jewish Anti-Judaism Papers

Anti-Semitism Discrimination and prejudice have been in our world for as long as humans have themselves. Discrimination has caused problems in societies all throughout history. But despite all of the terrible things that have happened because of prejudice and discrimination, it continues to live on in our world today. Anti-Semitism, prejudice against Jews, is a form of discrimination that has caused perhaps the most problems throughout history. Many people describe anti-Semitism as more than simply "prejudice" or "discrimination" against Jews. It is often the result of hatred and despise of the Jews, resulting in persecution and destruction. Anti-Semitism can often occur because a religious group is trying to make itself look better (Anti-Judaism/Anti-Semitism). Jealousy and envy are also major causes of anti-Semitism. A study on anti-Semitism found that people who are anti-Semitic are likely to also have negative feelings about African-Americans, Immigrants, gays and lesbians, illegal aliens, and women (JCRC - Anti-Semitism). As have all prejudices, anti-Semitism has been around a long time. It has been around since the time of Christ. One of the first events that gave rise to anti-Semitism was the Crucifixion of Jesus Christ (Mrs. Hahn's Notes). Jews were considered the murderers of Christ. Because of this hatred towards Jews, Jerusalem was destroyed, killing over 1 million Jews who resided there (A Calendar of Jewish Persecution). Jews were also persecuted extensively throughout the Roman Empire. In 135 AD, Roman Emperor Hadrian declared Jerusalem a pagan city. He forbade Jews to practice circumcision, the reading of the Law, eating of unleavened bread at Passover, or any Jewish festival. In 315, Constantine the G... ...ll eventually be gone along with all prejudices. Bibliography: BIBLIOGRAPHY Anti-Judaism/Anti-Semitism.

“Let Him Have It”: How does the director encourage the audience to feel sympathy for Derek and his family?

n this film â€Å"Let him have it† how does the director, Peter Medak, encourage the audience to feel sympathy for Derek Bentley and his family? Refer to three specific episodes from the film in you answer. â€Å"Let him have it† by Peter Medak is a very powerful film based on a controversial true story. The narrative is about a murder committed by Christopher Craig and Derek Bentley. Peter Medak, the Director, explained â€Å"I made this film to break hearts† and the way the scenes have been established and portrayed by the actors increase the emotional response of the viewer. The reason that this film is so effective is due to the amount of emotion and sympathy the Director portrays towards Derek Bentley. However, the film has a distinct bias towards Derek Bentley as it follows his characterisation compared to that of the other actors. Within this essay I will draw out the techniques the Director has uses to create a truly emotive production. I have chosen three episodes from the film where I believe the Director has emphasised the sympathy towards Derek and his family most effectively; the opening chapter, this depicts Derek when he was a young boy during World War II, the murder of the police officer, this is when Derek and Chris Craig attempt to break into a premises and the hanging. As the film opens it immediately provides the feeling of; sadness, sorrow, grief and unhappiness. The background to the credits are pitch black and the credits are written in old style, types set with white writing, establishing the feeling that the film is set in the past. The background music is sad, gentle and to some extent slightly emotional providing a sense of unhappiness. As the credits continue, the music gets louder and louder. This creates suspense in the audience, making the viewer believe that something is going to happen. The credits dissipate and then we can here bomb blasts, providing an indication that the first scene is going to be set during a war. This is effective because we can imagine the scene from the sound before we can view it. The first scene reveals the trauma suffered by people living in London during World War II. As the camera pans the set it shows the demolished houses and the devastated families with their personnel belongings scattered over the rubble. This creates a strong emotional response in the viewer for all of the people caught up in the air raid that has hit the street. The camera pans across a demolished house and the distraught family and then focuses into a body shot of a mother crying over her dead child. A lady calls for help, the attention is focused upon the lady shouting, â€Å"I have found him†, as they lift the rubble away, revealing Derek for the first time. The scene reveals a helpless, weak and vulnerable young boy surrounded by rubble and covered in dust. The Director increases the emotive effect of the scene by lighting the childs' face and zooming into the boy, which then reveals blood seeping out of his ear. The boy starts to shake and fit, this completed the effect the Director was aiming for, to create the initial sympathy for Derek. The trauma Derek experienced within the first scene could provide the reasons for his learning difficulties and disability. The Director has built this scene to explain to the audience what is happening to Derek and to create sympathy for him due to this incident, although at this stage it is unclear that he is suffering from. The Director has clearly identified this scene to underpin the whole film and I believe it provides a very descriptive and highly emotive start to the film. The film transports the viewer to when Derek was 19 years old, this is expertly delivered by focusing in on Derek in the rubble, followed by a close up of Derek as a teenager and pans out to show who he is with. The boys are about to break into an old persons shed, the mood is sad and sombre. The music is slow and deliberate, using the ‘miner keys' making this scene uncomfortable and provides the feeling that something bad is going to happen. Then you see the boys breaking into the old person's sheds, the lighting suggests Derek's innocence due to him being highlighted and the boys shadowed. The music gets louder and louder when the boys are vandalising the shed. Derek had no intentions of going into the old persons shed until one of the boys encouraged him, â€Å"Hoy Derek†. The Director is showing the audience how easily led and vulnerable Derek is whilst under the influence of others, which could be due to Derek's learning disability. It looks obvious throughout the scene that Derek is playing and he does not understand what he is doing wrong. He is trying to be part of the gang. During the scene Derek tries to eat the old person's supper that the other boys ruined with coffee, this is out of character for him and supports the conclusion that he is trying to fit in. When the man comes back the rest of the boys flee but Derek just freezes, he then starts fitting. This scene is powerful due to the high camera shot indicating his harmlessness and his lack of power. The Director uses this technique to establish sympathy for Derek, so you feel that he is just in the wrong place at the wrong time. The scene shows how the character of Derek is fragile and how easily he gives into peer pressure. This provides the impression of weakness within his character. The Director has again uses this scene to depict the major events that affect Derek's life and sets the scene of how Derek ends up in Kingswood Approved School (a young offender's institute) and raises the question as to whether it is his fault that he is in there. The scene has a big impact on the film; the audience would not feel as much sympathy for Derek because they may think that he was ill-disciplined and badly behaved for being in the institute. In the institute the music starts slowly to create sadness in the audience, as the camera tracks through the institute to a long shot of Derek in a long narrow corridor. This makes him look alone, harmless and sad as if he is waiting to be disciplined by the Head Master of the institute. The following scene is of Derek's father and the Head Warden in the office discussing Derek's low intelligence and his disability, epilepsy. This make the audience feel sympathy for Derek because he has been categorised and is not capable of fitting into a young offenders institute. Derek needs specialist help, which he never appears to receive. After Derek is released from the Institute he takes it upon himself to become reclusive and agoraphobic probably due to this being easier than facing life and its dangers. It takes allot of persuasion by his sister, whom he loves, to overcome this feeling and become more extravert. This also provides the audience with impression that he feels unwanted because of being rejected from the school. This could have resulted in how easy it was for Derek to join Chris's gang, because he felt wanted. Prior to the scene where Derek and Chris attempt to break in to the butchers shop, Derek is portrayed as someone who is trying to fit in and that is why he takes the keys to the shop. Throughout this scene there is clear evidence that Derek does not realise the potential implications of what he is doing, he believes he was only having fun. When Derek hands over the keys to Chris he comments, â€Å"you be in charge Chris,† as if he is a child. As they jump off the bus the boys play together, just like young children. Chris then hands a knuckle duster to Derek; he takes it like a child taking a new toy from his parents. This helped establishes to the audience that Derek's intention on the roof was not to kill but to just following the gang and try to be one of them, as portrayed in the gangster movies that the boys watched at the cinemas, prior to this scene. Chris applies a great deal of peer pressure to Derek, â€Å"are we going to do this or are you going to piss off too? † this shows how easily he is led by Chris. The Director shows a family observing Chris and Derek climbing up the fence, they immediately call the police. The audience is now aware that the police are coming; it also creates suspense, as you wonder what will happen to Derek and Chris if they get caught. The Director keeps switching to the police and their movements setting the scene for what is about to happen. The viewers can see the level of police presence surrounding the boys where as Chris and Derek are completely unaware as they are playing on the roof, running around like children catching each other in a school playground. When Derek and Chris are surrounded by the police, Derek exclaims, â€Å"my dad is going to kill me†, he could not think of anything worse than being reprimanded by his father. A police officer enters the roof and Derek struggles with Chris to try to prevent him shooting him, he warns the officer that Chris has a gun. Derek does not move when he was warned to stay still by the officer. It is at this stage when a critical point of the whole film is depicted, the officer asks Chris for the gun. Derek shouts to Chris â€Å"let him have it† meaning to give the gun to the officer; however Chris shoots the officer. Throughout this scene, Derek is portrayed as trying to help. The audience can feel sympathy for Derek because when he is trying to be of assistance but is being pushed around by the police. The audience do not feel as much sympathy for the policeman as they do for Derek because the viewer does not know about the officer's background, as we do with Derek, he is not characterised. The Director makes it very clear that Derek does intend to hurt or kill anyone and has no animosity towards the police officer. The Director shows a clear bias towards Derek in the way the scene is depicted. The audience could feel some sympathy for Chris because his brother has just been sent to prison; he shouted â€Å"you gave my brother twelve years†. It is effective when the Director shows a close up of all the policemen loading up their guns, and showing Chris loading his gun with six bullets, to show how outnumbered Chris is compared to the police. When the Police Officer was murdered, the Director includes a close up of all of the faces looking at the body, Derek was shocked, sad and stunned at what Chris had committed. When Derek walks towards the body he looks physically shaken, the viewer can feels a lot of sympathy towards him because he is genuinely sorry for the policemen. Derek knelt by the policeman's side, lowering himself down to his level, to show his respects towards the policeman. As the policemen take Derek away he does not resist arrest because it was never his intention to hurt anyone, after all he was just playing, or so he thought. In the third scene I have chosen, Derek and his family are awaiting the hanging. The Director creates a large amount of sympathy towards Derek and his family throughout the final episode. Once again the lighting and camera position is used to increase the emotive effect of the scenes. After Derek is taken down, following the court case, Derek and Chris are in two different cells looking at each other, this is the first time in the film where the Director places Derek in the shade. This is because he fared worse following the court case due to his age compared to that of Chris and he is facing execution. In the scene just prior to the hanging a light is tracked from the window through to the bath full of letters showing the support received for Derek's cause. The Director again is using this effect to show Derek's innocence, this creates sympathy in the audience as they know what is about to unfold and that it is unjust. When Derek's parents were informed that he should never have been tried in a court of law because of his mental age, the audience feel pity towards him because of what he went through in court, the stress of it all, when he should never have been there in the first place. The audience feels sympathy when he says â€Å"I am not afraid to die†; it gives the impression that he has given up and accepted the fact that he will die. It also emphasises the fact that he is still a child inside. The audience feels sorry for Mr. Bentley as the letter to the Queen is his last hope of saving his son. The Director has added this scene to depict the desperation of the Bentley family. During Derek's last conversation with his family he says goodbye as if he will never see them again, he tries to stay positive when his mum and dad are around â€Å"cheerio, see you tomorrow†. The music in this scene gradually gets louder to increase the emotion between the family also increases the sympathy towards Derek and his family, especially when you realise Derek can not touch or kiss his family for the last ever time before the hanging. They then place their hands together on either side of the glass barrier. Derek dictates his last words to a prison warden because he can not write for himself, he states in his letter to his mum â€Å"I tell you what mum, the truth has to come out, and when it does a lot of people will get hurt†. As Derek dictates this the camera gradually zooms in as he signs his name showing that he is struggling to spell his name and has the handwriting of a child. The Director chooses to show a scene where Derek's dad is in his bedroom holding his toy aeroplane, waiting for a verdict, this reminds us that Derek is mentally still a child. It makes you feel sorry for Derek because he is going to be executed for a crime that he would never be able to even conceive, never mind commit. You feel like they are hanging a child, an eleven year old child. What's more, in the scene the Director uses a close up of the officer scribing for Derek, the officer has a tear in his eye, as he sees the injustice unfolding. Within the execution scene there is a close up of the clock above the fireplace in the Bentleys house, this is very effective as it symbolises Derek's life ticking away. Mr. Bentley walks out into the middle of the street making him look small and helpless, like he has given up all hope. The street looks long and lonely, a postman walks up to Mr. Bentley giving him a pat on the back saying â€Å"this is all today† this shows the contrast in letters. A couple of days before there had been hundreds of letters being delivered, but now there was only one letter. This tells the audience that even Derek's supporters have given up on the possibility of a reprieve. As the clock is ticking away the camera delivers a high shot looking down on the family in the middle of their living room, hugging each other for comfort. The high shot makes them look helpless' you feel that there is nothing they can do to help Derek now. It makes the audience feel sorry for the family as they have tried everything they could; petitions, trying to get a retrial, writing to the queen etc, but in the end nothing had worked. The Director increases the sympathy for the family when he uses a close up of them crying together for Derek. This is jucsiposed to Derek saying his pray the Director shows the grieving and scared, sad Derek, to maximise the suspense and the sympathy for him and his family. Outside of the prison, protesters are singing hymns asking for God's mercy for Derek. The Director shows this shot of all the protestors singing, in front of the huge walls of the prison and a huge solid door. This shows that the protesters can't do anything for Derek but pray, sing and hope. This is creating sympathy for Derek because it is clear that everyone is on Derek's side even the officers inside the prison and the executioner. The executioner says to Derek â€Å"everything is going to be alright† to provide him with some encouragement. When it is time for the execution a clock is ticking, this links Derek's scene to his families scene, then the clock strikes 9 o'clock and Derek's breathing becomes louder. This is creating the tension in the audience, and also showing how nervous and scared Derek is towards the execution. Derek does not struggle or shout protesting his innocence, if the director didn't show this the audience would not feel as much sympathy for him. All the prison officers stopped working and after he was hung they bowed their heads showing their sadness for Derek. The protesters are now singing hymns for him as if they were at a funeral. When Derek is hung the camera closes in on his shoes in order to try to achieve the atmosphere, yet not showing the macabre hanging. The camera pans towards the light coming from the ceiling, as if Derek was escaping from the prison and going home or towards heaven. The camera flies over Derek's town into his bedroom and down the stairs, as if he was walking towards the living room to his family. The camera makes the audience feel like Derek is now a ghost or an angle. The camera zooms in towards Derek's family together in the middle of the living room. Then over their shoulders to the clock on the mantelpiece, it stops ticking. This sequence of camera shots maximises the sympathy towards Derek and his family and creates an overwhelming feeling of injustice. The Director used multiple techniques in the film to create sympathy for Derek and his family for example; panning, high shot, low shots, close ups, body shots, etc. The music throughout the film is similar, slow and, sad using the ‘minor key' to create a slightly uncomfortable feeling. The lighting of Derek and the people around him, for example, Derek was predominantly in the light when he was around Chris, this suggests his innocence. The cumulative effect of the techniques creates a powerful, highly effective and emotive film which provides the viewer with a compulsion to keep watching and till the conclusion. After the conclusion the viewer is left with a true feeling of injustice and sadness especially when you find out it is based on a true story.

Thermoelectric generator

Plantation for providing the necessary infrastructure out this project successfully. I also thank Dry. S. Maryanne, Dean, School of Mechanical & Building Sciences for his support and continuously encouragement in completing the project. I express my genuine indebtedness to Mr.. C. Rammers Kumar, Senior Assai. Lecturer, School of Mechanical & Building Sciences whose whole hearted guidance and valuable suggestions throughout this project helped us in completing it successfully, without which the project would not have attained a fine and final shape.I would also like to express our gratitude to all faculty members of the school for their timely encouragement and thought provoking suggestion to pursue our work. Last but not he least, we would like to thank all those who were directly and indirectly helped us in completion of this project. CHAPTER: I 1. 0 Introduction Man's constant evolution couldn't have been possible without fuels. Society is putting more emphasis on the mobile transp ortation sector to achieve future goals of sustainability and on low thermal efficiencies of ICC engine.About 60% of heat-energy liberated during combustion of fuel is not utilized in producing useful work and getting dumped into the atmosphere daily. To achieve these goals, society needs to jump to a new method to recover the lost part of exhaust energy. The recovering of heat from exhaust gases in automobiles is a typical area of generating steam (or) electricity using W. H. R. B. * (or) Thermoelectric. It depends on the basic principle of ‘Speck Effect'.It would be useful to demonstrate the potential of thermoelectric generation in the automobile industry using Thermoelectric Generator (Tee's). A thermoelectric generator, which can be driven by the temperature difference, incorporates fins into a thermopile to conduct heat toward or away from the alternating spaces between adjacent layers of different types of thermoelectric material. Vehicles are becoming more electrified and the higher electrical demands under nearly all driving conditions are required.On board electrical energy management and storage systems are more prevalent. TEE'S provides source of additional electrical power without increasing fuel consumption. The study reveals that about 6% of the exhaust energy can be taped from the exhaust there by increasing the thermal efficiency. It can be used to increase the overall efficiency of the engine without increasing the fuel consumption and thus there would be a separate source of the electricity that a vehicle needs for keeping its battery charged and for erring all of its on-board electric circuits. W. H. R. B. = Waste heat recovery boiler 1. 1 Problem Specification To design and fabricate the Thermo Electric Generator and its various components. To test the TAG under various conditions when used on Marti 800 standing engine. 1. 2 Objective To design the TAG and its various components using Silkworms (CAD) designing software and to fabrica te the same using various manufacturing processes. Then the manufactured model is tested for efficiency , power output under various conditions when tested with Marti 800 standing engine.CHAPTER: II 2 Literature Survey 2. 1 Thermoelectric Principle The Thermoelectric principle though established for long back found application only to the field of sensor industry. But recent advances in materials, especially in semi conductors have paved way for applications to the field of power generation. This project studies the application of Thermo electrics as a waste heat recovery solution in vehicles and their potential for the future. 2. 2 Speck Effect The Speck effect is the conversion of temperature differences directly into electricity.This effect was first discovered, accidentally, by the German-Estonian physicist Thomas Johann Speck in 1821 . He found that a voltage existed between wow ends of a metal bar when a temperature difference AT existed in the bar. Fig. 1. 3 – Speck ef fect AS and SUB are the Speck coefficients of the metals A and B, and TTL and TO are the temperatures of the two Junctions. The Speck coefficients are non-linear, and depend on the conductors' absolute temperature, material, and molecular structure.If the Speck coefficients are effectively constant for the measured temperature range, the above formula can be approximated as: Thus, a thermocouple works by measuring the difference in potential caused by the dissimilar wires. It can be used to measure a temperature difference directly, or to assure an absolute temperature, by setting one end to a known temperature. Several thermocouples in series are called a thermopile. This is also the principle at work behind thermal diodes and thermoelectric generators (such as radioisotope thermoelectric generators or Arts) which are used for creating power from heat differentials. . 3 Semiconductor Based Thermoelectric Though the thermo-electric principle was established in the early 19th century , it was only after mid-20th Century advancements in semiconductor technology, however, that practical applications for thermoelectric devices became feasible. Semi- inducting materials, (in conjunction with copper inter-connecting pads), have been found to offer the best combination of Speck coefficient, electrical resistively, and thermal conductivity.Semi-conducting materials provide another benefit, the ability to use electrons or â€Å"holes† (the absence of an electron in a crystal matrix) to conduct current. This last property is useful in assembling many thermoelectric Junctions in series to reduce the overall current flow in the device to manageable levels. 2. 4 Thermoelectric Modules (TEEMS) Bismuth Telluride-based thermoelectric modules are designed primarily for cooling r combined cooling and heating applications where electrical power creates a temperature difference across the module.By using the modules â€Å"in reverse,† however, whereby a temperature d ifferential is applied across the faces of the module, it is possible to generate electrical power. Although power output and generation efficiency are presently low, useful power often may be obtained where a source of heat is available. 2. 5 Teems for Power Generation Thermoelectric (ET) energy conversion for power generation is based on the â€Å"Speck effect†, where a temperature difference, TTS-TTS, across two dissimilar legs of nonconductor material produces a voltage, Avocado.This voltage is equal to the Speck coefficient of the material, a, times the temperature difference across the device. The dissimilar legs of semiconductor material, one p-type and one n-type, are called a thermoelectric couple. The p- and n-legs are Joined by an electrically conducting material at the p-n Junction. A thermoelectric module consists of a series of p-n couples, which are connected electrically in series and thermally in parallel. Electrically insulating material separates the electr ical connectors from the heat source and sink.When a temperature gradient is applied across the couple, the negatively charged electrons, e-, in the n-leg and the positively charged holes, h+, in the p-leg move from the heat source to the heat sink, conducting heat to the cold base. This flow of electrons and holes causes separation in an initially uniform charge carrier distribution, which results in a current flow, l, in the couple. A thermoelectric module used for power generation has certain similarities to a conventional thermocouple. With no load, the open circuit voltage as measured between points a and b is: V = a.AT Where: V is the output voltage from the couple (generator) in volts a is the average Speck coefficient in volts/K AT is the temperature difference across the couple in K where When a load is connected to the thermoelectric couple the output voltage (V) drops as a result of internal generator resistance. The current through the load is: ‘load = (a . I is th e generator output current in amperes RCA is the average internal resistance of the thermoelectric couple in ohms the load resistance in ohms The total heat input to the couple (Sq) is: Sq The . L) – (0. 5. 12 . + (KC .CAT) Sq is the heat input in watts Kc is the thermal conductance of the couple in watts/K couple in K 2. 6 Module Selection The is the hot side of the The selection of the appropriate module for power generation with required voltage and current output was done on the basis of literature survey and was found that bismuth telluride module best suited to our condition because of its high efficiency and high operating temperature. Bismuth Telluride module was used because of its easy availability, low cost and low operating temperature range with a considerable efficiency.Material used for fabricating the outer frame is Cast Iron of 5 mm thickness, Cast Iron is used because of its cheap and easy availability. Outer Frame structure made on Solid Works Real time out er frame Full Assembly of the Chamber After the frame was manufactured, it was connected to the main setup as shown low, The setup included the catalytic converter attached to the Marti 800 engine. The inlet to the frame (TAG) is attached to the exit of the catalytic converter and the exit of the frame is to release the final exhaust gas to the atmosphere through a pipe.Here heat energy is converted into electric energy using thermoelectric module and therefore two plates are used in this experimental setup one is hot which is in direct contact with the exhaust gases flowing through the frame on one side and the other side of hot plate modules are placed and the other plate is cold plate which is assembled with cooling chamber as shown below, Hot plate used here is Aluminum of 5 mm thickness, one of which side is connected to frame exposed to exhaust gases directly.The picture below is the hot plate when modules are attached to it with the interface pads in between to increase the t hermal conductivity and to reduce the thermal resistance between the plate and the module. The cold plate which is assembled with cooling chamber is shown below, After connecting all this plates and module the entire frame structure is made to stand connected to the engine as shown above in one of the figure, and below shows he final completed set up with the exhaust pipe connected to the frame.

Columbus and the Discovery of America essays

Columbus and the Discovery of America essays Columbus discovery of America and that of his travel to the East Indies by the Cape of Good Hope, are the two most unpleasant and significant events that have impacted modern civilization as we know it. By Columbus discovering America, he conquered, enslaved other cultures, destroyed lands, introduced disease and caused extinction, alteration of species and the destruction of the environment. Columbus is above all a villain of the modern age. Columbus alone was responsible for the enslavement and genocide of the people he had encountered in the new world that he had discovered. Upon his arrival in the Cape of Hope, he kidnapped twelve of the Arawaks and brought them back to Spain to learn Spanish. Exactly one year later, Columbus returned with the captives to the Cape of Hope and enslaved its first nations people in order to acquire its silver and gold. As Columbus demanded a quotient of gold for every day, those who refused or committed criminal offenses had their ears and noses severed off. As this continued to happen, the Arawaks became enraged and resisted. Columbus fought back by releasing his attack dogs that viciously tore apart and slaughtered the Arawak tribe. He then captured 1,500 natives and took them to Spain. Five hundred died on the voyage. While in Spain, it was demanded of the remaining captured tribe members to pay respects to the Queen Isabella and those who refused had their hands hacked off. The Ki ng later stated that the Arawaks had chosen their own fate and many women committed suicide and murdered their own children. Columbus and his crew brought disease over to the new land. Within the next fifty years, over 3,000,000 Arawaks died because they did not have the same immunities to these diseases as the Spaniards (ex. the common cold, small pox). Before the disease that the Spaniards exposed to the natives, the Arawaks had particularly good health. Specific diseases that were s...

Scientific Literacy And The Frankenstein Monster English Literature Essay Essay Example

Scientific Literacy And The Frankenstein Monster English Literature Essay Essay Example Scientific Literacy And The Frankenstein Monster English Literature Essay Essay Scientific Literacy And The Frankenstein Monster English Literature Essay Essay Essay Topic: Frankenstein Scientific literacy is the ability to grok scientific constructs which are of import in doing single determinations and take parting in activities that are good for the societal, political and economic personal businesss of the society. It encompasses inquiring inquiries and happening replies to affairs that may originate due to curiosity about mundane life. To acquire an penetration in scientific literacy, an person should be able to read as much scientific works as he or she can in order to do an informed determination about certain phenomena in the existent universe. Harmonizing to Lee Gentry ( 2000 ) a society with a high figure of scientifically illiterate people is at a disadvantage because such people will non understand things that go on around them because most of the things that affect our life have either a technological or scientific background. Therefore illiterate people will non be able to even debate on issues impacting the environment, technology and medical defence proposals. Harmonizing to Dr Phil Science literacy enables an single to understand the universe around him through observation of the critical factors around him or her. Science literacy enables people who have done scientific discipline to be able to understand the current universe that is driven by scientific discipline and engineering. This literacy enables an person to be able to separate between fact and guess which will be really utile in separating the truth in media and political sphere. This book interested me because of what the author handles his authorship from the beginning of the book to the terminal. This book has a batch of pragmatism which I like so much ands in add-on the book is a Gothic novel which I like so much. Another ground that made my choose this book is when I was with my uncle and as he finished watching another film called the lamia, and I started visualising the stormy and dark dark and this gave me the impulse of desiring to read this book. My uncle was really enthusiastic when he was speaking about this book and this excessively encouraged me to travel and look for this book because I wanted the written version and non the film version of the book.Infact the transcript of the book that I have now is the fist I read during my 5th class and it is still in good status as if it was still new. Another ground that made me take this book is that I have been making a batch of research on monster, lamias and wolves but I had non done so much on the Frankenstein monster and his Godhead and this prompted me to travel and look for this book to be able to cognize more about these monsters. Before I read this book I did non understand the superior ability and strength of the monsters coupled with their power to make excess ordinary things. There are so many things that excite me about this book including the fact that the author has foremost because the author has done the authorship in the best manner that he could in covering with the horror narrative in order to convey about the significance he wished to. The incorporation of the monster universe into the existent universe of human existences makes the book an interesting work to read due to the struggle between existent human beings and the monster universe What the writer eventually latched onto when she found her narrative was nt a shade narrative at all. Using thoughts of Erasmus Darwin s, she succeeded in making the first echt science-fiction narrative. Through the unreal creative activity of life by utilizing scientific procedures and clearly saying its effects the author is able to capture the attending of the readers. The original Preface ( which, harmonizing to Mary Shelley, is the work of her hubby, poet Percy Shelley ) makes the science footing clear, as opposed to a supernatural one. This is another difference in how I approached Frankenstein this clip that I read it: I paid more attending to its science-fiction premiss alongside its open Romanticism and its interaction with the abandon of human nature and the existent natural states. Although Victor Frankenstein, a immature medical pupil and non a physician as frequently portrayed in other media, is the nominal hero and the storyteller who tells his narrative to the captain of a ship trapped in north-polar ice, I feel small understanding for him. Even as his friends and household dice at the monster s custodies, I felt a awful disfavor for Frankenstein because he shows such moral cowardliness. It is nt merely that he backs off from his creative activity, declining to take duty for life he created, and therefore estranging it. He besides refuses to step frontward when the amah Justine gets unjustly accused of slaying Frankenstein s youngest brother. Victor knows the monster did the title, but justifies his refusal to state anything about it behind the weak alibi that the jurisprudence will take attention of it. Victor merely takes action when it s excessively late and his devastation of the monster s possible mate-based on a fright of them propagating a clump of ugly children-really puts me on the monster s side. I really experience better about Peter Cushing s cold, barbarous murderer version of Victor Frankenstein in the Hammer Films ; at least he stood up for what he believed in. It s impossible non to experience for the Frankenstein Monster ; he speaks as us, people who wonder what our being, merely his calamity is more specific, and he can happen a focal point for his fury: Accursed Godhead! Why did you organize a monster so horrid that even you turned from me in disgust? God, in commiseration, made adult male beautiful and alluring, after his ain image, but my signifier is a foul type of yours, more horrid even from the really resemblance. Satan had his compassions, chap Satans, to look up to and promote him, but I am lone and abhorred It interested me how much the monster resembles the modern stalker scoundrel seen in films and literary thrillers: a character of relentless cunning that Hunts and torments the supporter, able to look anyplace he chooses and inflict hurting. Although Frankenstein does nt dismay the manner it must hold when it was foremost published, it does incorporate intense suspense as the monster tracks down Victor s loved 1s ( I will be with you on your nuptials dark! ) and so eludes him in a passionate pursuit to the terminals of the Earth. While reading the novel, I noticed a few topographic points where Del Toro could graft on a dark action narrative into the events. The long pursuit into the ice has many topographic points where the monster could turn aside and acquire involved in some absorbing adventures. AndaˆÂ ¦ what if the monster does nt perpetrate suicide as he says he will at the terminal? Where might he hold gone, and what would he hold to make to happen a manner into human society? I truly hope Guillermo Del Toro gets his opportunity to turn to these thoughts, and hopefully with Doug Jones in the portion of the Monster. My suggestion for Victor Frankenstein, if he appears in the film, is James McAvoy. The most important thing that I have learnt from this book is that inanimate things can be used efficaciously to stand for certain properties that are characteristic of human existences in the existent universe fro case the author presents a close connexion between the existent people and human like animals like monsters. Another thing that can be learnt from this book is that there is a important relationship between scientific discipline and nature because what is predicted by scientific discipline automatically happens because scientific discipline is all about existent life since it s a manifestation of nature. A good illustration is when the monster appears as a craft character that is merely after torturing its victims. This is besides characteristic of existent universe human existences who can make something bad to person whom they feel have offended them. It can hence be concluded that the novel is a good manifestation of the direct relationship between fiction and existent universe because the big portion of this book is all about fabricated characters that represent existent human characters. It should be an encouragement to our citizens to read plants of fiction about scientific discipline in order to acquire an penetration into the scientific cognition that will assist them to be able to do statements particularly when argument about scientific affairs is made in the public sphere.

Emergency Medical Services - Research Paper Example It is necessary to immediately begin appropriate resuscitation and at the same time arranging for possible hospital care. Clinically, the presentation of a patient with cardiac arrest is that of sudden loss of consciousness accompanied by loss of pulsation in any major artery such as femoral or carotid. The speed of pre-hospital care is the key since even very minor delays may adversely affect prognosis (Ewy, 2007). It has been recommended that the time taken to assess the circulation in such patients should not exceed more than 10 seconds, and wasting time for noting other confirmatory clinical features would be waste of time without any contribution to the diagnosis.

Gay Marriage Essay Example | Topics and Well Written Essays - 1250 words - 1

Gay Marriage - Essay Example Massachusetts became the first state to legalize marriage between same-sex couples on May 17, 2004, as a result of a November 2003 decision by the state’s highest court that denying gay and lesbian couples the right to marry violated the state’s constitution. (Smith, 2005:2) Though homosexuality has been being practiced for centuries in almost all parts of the earth, both explicitly or secretly, and men and women belonging to various age groups get indulged into it, yet an overwhelming majority of human societies apparently denounce the same provided it challenges the moral values prevailing in the culture as well as unrestricted permission of the same may put the reproduction system as well as survival of human race at grave jeopardy. Marriage’s role in upholding respect for the transmission of human life is the first event in procreation. Humans undergo unprecedented challenges to that respect because of new techno-science that opens up unprecedented modes of t ransmission of life. (Somerville, 2003:3) The religious leaders including rabbis, monks, priests and bishops particularly condemn and censure same sex relations and marriage due to the very reality that the Scriptures do not allow it at any cost. According to Bible, if a man also lies with mankind, as he lieth with a woman; both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them. (Leviticus, 20:13) It is therefore, the Abrahamic faiths, including Judaism, Christianity and Islam, rebuke gay sex without granting any space to this activity. Though several western countries, having Christians in majority, have displayed relaxation to voluntary gay sex, yet the Muslim states are still reluctant to bestow such rights upon their subjects. They cite the example of the people of Prophet Lot, tale of whom has manifestly been narrated in the Holy Qur’an, who were pelted with stones from the heavens and destroyed en masses for transgr essing from the right path for openly developing male-male relationships and thus ignoring their women and putting reproduction at stake subsequently. (Al-Aaraf: 80-82)Â  Moreover, other conservative faiths including Hinduism and Confucianism also denounce gay marriage on religious grounds, without giving slightest way to the same. Gay sexual union observes opposition beyond religion too, as a large proportion of scholars, thinkers and philosophers consider it as the violation of morality and thus perversion in the real sense. They declare homosexuals as mentally retarded patients, who are undergoing psychological and emotional collapse or disorder because of some deprivation or incident they have undergone in their past. They are of the opinion that the children who were ransacked, abused and molested could turn as murderers, child molesters, pederasts and rapist as well while adopting criminal line on becoming grown ups. It is therefore the homosexuality cannot be tolerated or ne glected as a curse for society. The price of toleration of serious deviance from a society’s constitutive morality is the loss of a distinctive form of interpersonal integration in community understood as something worthwhile for its own sake. (George, 1993:65). The opposition of gay rights is not confined to the

Political Context of Social Policy Assignment Example | Topics and Well Written Essays - 750 words

Political Context of Social Policy - Assignment Example According to the discussion  social policies are those which are designed and developed to respond to the social issues of a society. These policies are formed by the government or by private organizations in order to fulfill the social needs of the disadvantaged citizens. Social policies are mostly developed for the betterment of the society and to benefit human welfare. However, there are many agencies that are set up to design social policies by the government.  This paper highlights that  it is not only important for the government agencies to look at the social needs before implementing a policy, but also important to consider the political environment of the society before a policy is implemented. Political parties hold great importance in a society and they play the role of major stakeholders in public welfare policies. The political environment determines whether the political parties approve the social policies or not because if they don’t, it might result in di sturbance in the society. In order to make sure that the social policy is effective and successful, the agencies must take the consent of the political parties and consider the political environment. A distressed political environment in the society would rather result in a negative effect of the policy.  There are several stakeholders that need to be involved in the technical discussions and considerations of implementing a social policy. These stakeholders may be government authorities, ministers, political parties, citizens, and the targeted population.

Palm oil Essay Example | Topics and Well Written Essays - 500 words

Palm oil - Essay Example The UK is the wealthy nation which dominates the poor nation of Indonesia which has an abundance of cheap labour and land on which palm oil can be grown successfully. Instead of development, the production of palm oil in Indonesia takes place at a cost to the indigenous people and to the environment. The benefits derived from the production of palm oil also accrue mainly to the developed country at the expense of the relatively undeveloped Indonesia where land which should be preserved for the protection of the environment and biodiversity is being burnt in order to supply palm oil cheaply to Tesda’s supermarket chain and other company’s. Instead of development Indonesia is faced with displacement of its people and depletion of its resources. The soot from burning has affected the operations of the airline industry and will therefore have a negative effect on the economic development of the country. The preservation of the environment is important in the development of any country. The burning of the forests will have dire environmental consequences for the people of Indonesia. With the increasing and negative effects of climate change countries around the world are taking the necessary steps to reduce the emission of greenhouse gases in the atmosphere while this is taken place in Indonesia. These events indicate that Tesda has not adopted a model for corporate social responsibility with all the negative events including corruption, lack of dialogue between groups affected by the production of palm oil and poor labour standards employed. These along with the death of persons who speak for their rights are unacceptable. The stakeholders that have legitimate claims on Tesda are the indigenous people of Indonesia whose lives have been negatively affected by plantations in which Tesda has a stake, the people who work on these plantations, suppliers to its processing plant in the Netherlands and

Judicial Review Research Paper Example | Topics and Well Written Essays - 1000 words

Judicial Review - Research Paper Example The increasing relevance and growth of judicial review is as a result of the growth of the administrative functions and powers in the modern world and can be understood from a historical perspective. The period before 19th century was characterized by a societal mode of life known as laissez faire which connotes total individual freedom, contractual freedom, a free individual enterprise which diminish the government control and functions. In a laissez faire society the role of the state is negative and is limited to defending the country especially from external aggression. The advent of industrial revolution in the 19th century manifested that the bargaining power of individuals was not equal and that un-controlled bargaining power would lead to exploitation of poor majority by the rich minority. This makes it important for the State’s intervention in individual matters. The state thus took more positive and active role in matters which affected the citizens directly. This le ad to the birth of the Social Welfare State, whose advent led to a phenomenal increase in scope and content of the functions and powers of the State. The state from then on, through the machinery of state corporations and executive arm, took over a very large portion of what was matters of private individuals and started to profoundly control what remained in the private domain. (Jain, 3) an administrative law author summarised the functions of the state in a social welfare system as follows: â€Å"†¦Ã¢â‚¬ ¦.the state today pervades every aspect of human life; it runs buses, railways and postal services; it undertakes socio-economic planning, improves slums, plans urban and rural life, looks after health, societal morals and education of the people, generates electricity, works mines and operates key and important industries; acts as an active instrument of socio-economic policy, regulates individual life and freedom to a large extent; benefits its citizens and imposes social control and regulation over private enterprise.† A state has three organs which are the judiciary, the executive and the legislature which perform independent and different functions. Increase in the state functions would obviously mean increase in work for all state organs. But this is not the case as the largest range of the powers and functions of the state has been taken by the executive arm which is also known as the administrative arm of the state. In the modern times the executive arm performs functions which are ex facie and which belong to the other organs of the state. The executive performs the legislative power by making a plethora of rules, orders, by-laws and regulations. This is designated as subordinate or delegated legislation. The executive also performs adjudicative powers over disputes through the commissions, tribunals and many other quasi- judicial bodies which have diversified jurisdiction, structure, powers and procedures. They make binding decisions li ke those of ordinary courts. The reason for subsidiary legislation is that the legislature lacks time and expertise to handle the mass all the legislative detail required to govern a state. The

Abraham Maslow Research Paper Example | Topics and Well Written Essays - 3750 words

Abraham Maslow - Research Paper Example Though he focused on political and religious material, but worked thru issues about senses, imagination, knowledge, language, and passions. Other contemporary philosophers (Munger, 2003) like Rene Descartes, Baruch Spinoza, and G.W. Leibinz contributed in this progress by studying human mind’s relation to the body. Further development in psychology stressed interaction of physiology to psychology. Later development established psychology as science, and concluded that mental activity could be quantified thru research. Charles Darwin using the concept of principles of natural selection brought further development in psychology. Contribution of principles of the unconscious mind by Sigmund Freud laid the foundation of psychoanalytical model. Different fields of sciences, like education, anthropology, and medicine borrowed this model in their disciplines. In the 1920s and 30s American Psychologist John B. Watson (Munger, 2003) introduced a concept in psychology where he explained animal and human behavior thru environmental stimuli. According to his suggestion, psychology should involve solely with sensory stimuli and behavioral response. Others at the same time suggested that psychology should investigate human thought and behavior as a whole, instead of breaking it down into isolated instances of stimulus and response. The aforementioned discussion points out that psychology is a discipline that studies behavior of humans and other animals in their interaction with the surrounding world. Traditional concept of psychology is perceived thru restoring imbalanced mental activity to a normal condition. Traditional psychology did not pay much attention to the concept of human potential that conceals what humans can become. In other words, traditional psychology paid remarkably little attention to the psychological development of human, how to generalize it, and what mechanisms controls it. In the 1950s and 60s Abraham Maslow and Carl Rogers developed a new conc ept of psychology (Boeree) that considered the psychological growth of people who are properly adjusted. This method is named as Humanistic Psychology, which asserts people make rational, conscious decisions regarding their lives and suggests that individuals tend to reach toward their greatest potential only after solving issues related to specific needs. Thus, this theory incorporates the possibility of human actualization into its practice. The aim of this work is to examine the life of Abraham Maslow, his concept of the model of human needs, its interpretation, analysis, and application. Abraham Maslow: Highlights from Biography Abraham Maslow, a son of Jewish Immigrant from Russia was born on April 1, 1908 in Brooklyn, New York and died in California on June 8, 1970 (â€Å"Abraham Maslow†).

The Life of Saddam Hussein Essay Example for Free

The Life of Saddam Hussein Essay Saddam Hussein was born on April 28th 1937 in Al-Awja, a small Iraqi town. At a young age Hussain fled from his abusive father to live with his uncle who was a devoted Sunni Muslim. His uncle had Saddam attend a nationalist secondary school and after graduating Hussein studied law for three years but didnt earn a degree until he was older. At the age of 20 Hussein joined the Arab Ba’ath Socialist Party also known as ABSP. After receiving six months of jail time 5 years previous for political activities against the government he was again sentenced to jail for being part of ABSP. But while in jail Hussein was elected part of the ABSP’s Pan-Arab National Leadership. Saddam later would escape from jail and rise through the Ba’ath Party ranks. He earned a degree in law from Baghdad university which helped him become a powerful politician who was known for being â€Å"effective and progressive†. In 1972, he began developing a chemical weapons program and signed a treaty with the USSR for their friendship and cooperation. Throughout the 1970’s, Saddam Hussein led his nation through urbanization by providing electricity to rural Iraq and also developing national infrastructure. Hussein also helped his image grow when creating a state of the art public health system which was considered to be one of the best in the Middle East at the time. Hussein continued his accomplishments when being elected assistant secretary general of the National Pan- Arab Leadership. In the year 1979 Saddam earns three create accomplishments to his resume. First off, he was elected president of his homeland. Second, he was elected secretary general of the regional leadership of Ba’ath. Lastly, he was elected chairman of the Revolution Command Council. The 1970’s can be argued to be Saddams best decade before destroying his image throughout the world. After becoming president in 1979 Hussein started a war with neighboring Iran in 1980 after invading one of Iran’s oil provinces. It only took a year or two before Saddam used the chemical weapons produced from his chemical weapons program which began in 1972 to kill thousands of innocent people. Hussein showed his ruthless leadership when it came to those who were possible threats when Dr. Ibrahim (A man who was responsible for the death of a patient, and was later arrested) was found disassembled when delivered to his wife. Hussein once again displayed his cruelty when using his chemical weapons once again in 1988 in a Kurdish town killing 5,000 civilians. Soon after the war ended in a stalemate leaving both countries economies in ruins after borrowing tens of billions of dollars from other nations. In 1990, Saddam invaded the oil rich and prospering Kuwait so that Iraq could sell the oil to help pay back their debt. Hussein argued that Kuwait was â€Å"historically an integral part of Iraq. † After invading Kuwait Saddam merged the two countries on August 2nd. The invasion of Kuwait started a Gulf War which lasted only a year. In 2002 Saddam Hussein was elected president for the 5th straight time winning 99 percent of the vote in a noncompetitive poll. A year later Hussin denies inspectors to search for any nuclear weapons in his country. Ultimately Bush gave Saddam and ultimatum for him and his two sons Uday and Qusay to flee the country in 48 hours or the U. S. will use force. Saddam stood his ground and told the U. S. moved in with Operation Iraqi Freedom. Iraqs capital was soon taken over forcing the nations president to flee. Nine months later Saddam Hussein was captured by coalition forces and handed over to the Iraqi government. Hussein was first trialed in July of 2004 for the death of about 150 Shi’a. On October 19th trial began in Iraq, Hussein refused to show his face or reconize the authority of the court. A second trial opened up in 2006 after charges of genocide. On the 5th of November Saddam Hussein was convicted of the charges and is sentenced to death by hanging. Two others were also convicted and given the same punishment. Saddam Hussein was hung on December 30th 2006 at the age of 69. Saddam Hussein wasn’t always known for being a cruel and evil leader. During his 20’s and 30’s he helped his country prosper and urbanize. He donated money to farmers, brought electricity to most of Iraq, and many other notable contributions to his country and the Middle East. When Saddam Hussein became president that is when things started to go down hill for his reputation of being caring for his country. The beginning half of Saddam Hussein’s life can be inspirational, but the second half can be classified as evil and an example of what leaders can do when feared by most of the world.

Manfred Ewald who was the head of Olympic sport committee in East Germany, and Dr. Manfred Hoeppner who was the sports doctor at that time, were responsible about giving the athletes banned substances intentionally without their knowledge. This results in severe complications in the athlete’s health such as liver dysfunction, cancer, hormonal changes and infertility. From 1966 and on, many doctors and coaches in East German follow a plan which was sponsored by the government known as â€Å"systematic and overall doping in competitive sports†. After the collapse of East German and Berlin Wall fall in 1989, many athletes confessed about the pills and injections that were given to them. Kornelia Ender, Barbara Krause and Carola Nitschke were three of the thousands of East German athletes who had provided with steroids. Heidi Kreiger was also one of the athletes that was provided with steroids heavily and this was the main reason that force her to make sex-alteration operation. 2. Pan American Games in 1983 IOC included testosterone in the banned list in 1983 and it was the first endogenous substance to be tested at that time. The test was based on measuring the testosterone to epitestosterone (T/E) ratio. (1) The first drug testing for steroids was at the Pan America Games in Caracas and Venezuela in 1983. Around 15 athletes were caught at these games. Jeff Michaels, the American weightlifter, and Guy Greavette, the Canadian weightlifter, were tested positive for steroids. They returned their medals and being suspended for 2 years. (5,7) Many athletes of the U.S track-and-field team withdrew from the game rather than being captured. (7) 3. Ben Johnson’s scandal In 1988, the Canadian Ben Johnson was stripped of his gold medal at 100 meters after he has been tested positive for the anabolic steroid stanozolol at Seoul Olympics. Johnson has been banned from competition for 2 years.(7) 4. Michelle Smith: the Irish swimmer(5,7) In 1998, the Olympic champion swimmer Michelle Smith was tested positive for banned substance at her home through out-of-competition testing. The test was positive for alcohol in an amount that would be fatal if taken by an athlete. So FINA, the international governing body for swimming, concluded that the urine sample was treated with alcohol as a masking agent and Smith has been suspended for four years. 5. Chinese swim team(5,7) The Chinese national swim team has been used anabolic steroids, erythropoietin and human growth hormone in the last 15 years. In 1992 Barcelona Olympics and 1994 world championships, china won a high number of gold medals. In world swimming championships, a world records was set by women swimmers, and this causes suspect that they were using drugs. In 1994 at Asian Games, eleven athletes were caught as drug abusers for dihydrotestosterone. Since 1990,over 40 Chinese swimmers were tested positive for abused drugs and at that time china reached the peak for drug abuse over the swimming countries. 6. Tour de France(5) Doping by cyclists arises since 1967 after Simpson death at Tour de France due to amphetamine misuse. Drug abuse by cyclists continues and in summer 1998, the Festina cycling team was pushed out from the competition at Tour de France after the French Officials found EPO in their masseur’s car. After investigations, six of Festina’s nine riders confessed that they had taken abused drugs. Later on, the leader also has failed drug tests for anabolic steroids. Also in 2002, Stefano Garzelli, the leader of the Vini Caldirola team, has failed drug test for probenecid, a diuretic which is used as a masking agent. Also in the same year at Tour de France, the Spanish cyclist Igor Gonzalez de Galdeano, was tested positive for anti-asthmatic drug. In January 2004, two cyclists in the Cofidis team, which is one of the top teams in france, were caught as drug abusers for EPO and amphetamines. 7. Steroids in baseball (5) In 2002, a report was published by the Sports Illustrated and the National League MVP Ken Caminiti stated that â€Å"at least half the guys are using steroids.† In 2003, the Major League Baseball revealed that around 7% of 1438 tests on all players were positive for steroids. 8. Doping in skiing(5) Drug abuse in cross-country skiing has been spread for years especially with EPO. In 2001 world championships in Finland, six finish skiers have failed drug test for HES which is a plasma volume expander. Three skiers at the Salt Lake Games were tested positive for the drug Darbepoetin which is a synthetic compound of the natural hormone EPO. Two of these athletes Olga Danilova and Larissa Lazutina were Russian medalists but later on, they were stripped of their medals and the gold medal was awarded to the Canadian Beckie Scott who ended third. 9. BALCO scandal BALCO is Bay Area Laboratory Cooperative which is a company that provides nutritional supplements. Victor Conte built BALCO in 1984 and he followed a system for analyzing urine and blood in order to prescribe supplements that replace vitamin and mineral deficiencies. Tetrahydrogestrinone is one of banned substances that was used by BALCO and was undetected by drug testing. THG or â€Å"The Clear† is an anabolic steroid that can reduce fatigue during training and can increase the muscle mass. In 2003, the USADA, United States Anti-Doping Agency, developed a test for THG after receiving a syringe from anonymous (US track coach Trever Graham) containing THG and claiming that most athletes are using this drug. Don Catlin, succeeded in developing the test and he tested the urine samples that were taken from athletes at the US championships and numerous tests came back positive for THG(8,9). Athletes that were involved in BALCO scandal were Kelli White, Marion Jones, C.J.Hunter, Tim Montgomery, baseball star Barry bonds, and NFL’s Bill Romanowski, and Dwain Chambers. In 2004, Dwain Chambers who was the European 100m championship at that time was banned from competition for 2 years. 100m and 200m Champion kelli white was banned for 2 years as well. USADA convicted BALCO, for the distribution of THG. In 2005, Victor Conte was jailed for four months. Greg Anderson (Barry Bond’s trainer) was jailed for three months.(9,10,11,12) 10. Ma’s runners Ma Junren was the coach for the world female championships runners(13). In 1993, Ma’s Chinese female runners won three gold medals at the World Track and Field championships in Stuttgart and also in 1997 they set world records. From that time there was suspicion that the runners were using banned substances(13,15). A doping scandal for Ma’s runners arose before the 2000 summer Sydney Olympic(14,15). Top runners like Liquing Song and Lili Yin had failed drug test for testosterone during an out-of competition testing in 2000 and the Ma’s Chinese runners were evicted from the Olympic team(13,15). History of drug testing: Doping was also done for race horses not and only for humans. The first drug test was done for alkaloids on the saliva of horses in 1910 by a Russian Chemist in Vienna.(1,2) Drug testing on human urine started in 1950s after the wide spread abuse of amphetamines. (7) After British Tommy Simpson death from amphetamine abuse at Tour de France in 1967, IOC established the Medical Commission and a list of banned substances was established by the IOC. Professor Beckett was a member in the Medical Commission at that time and he developed methods for detection of stimulants ,i.e. drugs that were used† in competition†. (3,7) Methods of Beckett for drug testing were first used in 1968 at Mexico City Olympic competition and these tests were for non-steroidal drugs (narcotic analgesics and stimulants) and there was no tests for anabolic steroids.(7)(3). The first formal drug testing programmes for narcotics and stimulants was in 1972 at Munich Olympics. These tests were done at the competition periods. The abuse of Anabolic steroids became prevalent in 1970s and its use was banned in 1974 by the IOC and added to the list in 1975(1) p313. The first formal steroid testing program occurred in 1976 at Montreal Olympics using radioimmunoassay screening for detection its presence and GCMS for confirmation. (7,19) In and out of competition testing: At first testing programmes were based on tests during the competition periods. But later on it was recognized that these tests were of limited value to catch up the cheats. Athletes learn how to defeat the testing programmes by calculating the clearance time of the drug in the body so they could avoid its use before the competition periods. Form here came the â€Å"out -of -competition† testing programmes to catch the cheats for drug abuse. â€Å"Out of competition testing† started in late 1970s. The first out of competition testing was conducted in 1977 by Norway and in UK, it started in early 1980s. However, the â€Å"out- of -competition† testing did not expand globally until the establishment of WADA in 2000. WADA established out-of-competition testing programmes and it was followed globally from that time.(1) p314-315 Classification of Abused Drugs Doping classes and methods examples Anabolic steroids Testosterone, nandrolone (discussed later Blood Doping blood transfusion(discussed later) Stimulants Amphetamine, ephedrine, cocaine, caffeine Narcotics Morphine, Methadone, Codeine Peptide and glycoprotein hormones Human growth hormone, corticotrophin, human chorionic gonadotrophin, erythro poietin Diuretics and masking agents Acetazolamide, Furesamide, Probencid Beta- blockers Atenolol, Propanolol, Metoprolol Atenolol, Propanolol, Metoprolol Anabolic steroids (discussed later) Blood Dopping (Blood Transfusions) ( discussed later) Central Nervous System Stimulants Athletes often use stimulants to enhance alertness and reduce fatigue i.e. increase physical and mental performance.1p41. These are more used on the day of competition to reduce the sensitivity to pain of athletes if they got injured; however, nowadays they are used during training to increase training time. Amphetamines Amphetamine is a synthetic compound (1920), it was developed as an appetite suppressant and for treatment of narcolepsy, to fight fatigue and to enhance alertness, but later it was withdrawn from clinical use due to the development of tolerance. P42 Methamphetamine is very addictive stimulant, related to amphetamine with more longer lasting and toxic effects on the CNS. Mechanism of action: These are indirectly acting sympathomimetic amine. They enter neurons and act presynaptically to release stores of noradrenaline, and dopamine from nerve endings; they also block noradrenaline and dopamine transporter reuptake and inhibit MAO. They include Dexamphetamine, Methamphetamine, Phenmetrazine, and methylphenidate. Routes of administration: Amphetamine can be administered orally, nasally, and intravenously. Amphetamine itself is not very effective if smoked. Methamphetamine is smokable form and it is becoming increasingly popular as a drug of abuse. Effects of Amphetamines in Sport: Athletes often use amphetamine to reduce fatigue, increase alertness and concentration, increase euphoria and to tolerate painful injuries.p42. p72 Side Effects: The most important side effect is heart stroke.p72. Amphetamines cause peripheral vasoconstriction and thus increase blood pressure. The body overheats and cannot regain its temperature resulting in dehydration.1.p42 The second side effect is that the euphoric action may affect the awareness of athletes and thus they fall in misjudgements. Cases of amphetamine abuse: Amphetamine use was spread around the time of the Second World War, to decrease fatigue of the troops. Later, its use was spread among athletes in 1940s and 1950s. 1.p30. its use atarted to be controlled under the UK Misuse of Drugs Act 1971. In 1960, the cyclist, Knud Jenson, died due to amphetamine abuse in the intense summer heat of Rome Olympics.1p72-30 In 1967 Tour de France, the British cyclist, Tommy Simpson, died as a result of amphetamine abuse while climbing the infamous Mont Ventoux. His death was due to cardiac arrest.1p72 In 1997,American Footballers, (Clarkson and Thompson), withdrew from play due to amphetamine abuse which was taken to tolerate injuries.1p72 Effect on behaviour Mandell (1979), Golding(1981) In 2002, the British skier Alain Baxter, had lost his Olympic bronze medal and he was banned from skiing from March until June, due to positive test of Methamphetamine( l-form which is found in OTC vicks inhaler. IOC test do not distinguish between l- and d- form. D-form is used as performance –enhancing drug. Later on, Baxter’s name was cleared as being a drug cheater and it was approved that the drug was l- form.(16,17,18) Ecstasy It is a synthetic amphetamine derivative. It was synthesized in 1914 as an appetite suppressant. It has stimulant amphetamine like properties, now commonly used in dance clubs but it may be misused by athletes. In UK, it was classified as an illegal substance since 1977, and in USA its use was under control since 1985. Since 1990, there were no reports for ecstasy misuse by athletes.p73 Ephedrine and related compounds Ephedrine is a natural product occurring in the plant genus Ephedra. Phyenylpropanolamine and pseudoephedrine are synthetics. These are used to treat cold symptoms as bronchodilators.1.p73.p42. Mechanism of action It has sympathomimetic action. These deplete noradrenalin from neuronal storage sites resulting in indirect effect on sympathetic neurons and CNS.1.p73 Routes of administration Ephedrine and phenylpropanolamine are found in cold medications (in UK and USA) which are taken orally. Phenylpropanolamine is now prohibited by US authorities. 1.p74 Effect of Ephedrine in Sport Ephedrine is misused by athletes for its euphoric action.1p42. Athletes try to misuse ephedrine because its use could be negotiated due to its presence in the over-the-counter medication.1p42 Side effects The main side effect is the cardiac arrthythmias. Cases of Ephedrine abuse Pseudoephedrine, phenylpropanolamine, and phenylephrine were removed from WADA list for banned substances in 2004, but they are still controlled by WADA for athlete’s misuse. Ephedrine is still on the banned list.1p76 In 1972 Olympics, the US swimmer, De Mont, was banned due to urinary ephedrine positive test in which he declared that its presence due to a medicine.1p76 In 1988, Linford Christie, at Seoul, was tested positive for cold cure substance, and he was nearly to lose his silver medal. Cocaine Cocaine was a component of Coca-Cola until it was classified as an illegal drug and it was removed in 1903.(1)The main therapeutic effect is its use as a local anaesthetic. Mechanism of action Cocaine exerts its sympathomimetic central effects by inhibiting the reuptake of noradrenaline, dopamine, and 5-HT into presynaptic terminals of the mesolimbic reward/pleasure pathway. Routes of administration â€Å"Snorting† is the most common route of administration of cocaine. The powder is drawn up to the noise, and is absorbed through the nasal epithelium into the blood. It reaches the brain within about three minutes. It can also administered by intravenous injection, reaching the brain in 15 seconds and the effects last for 15 minutes. Crack cocaine is smoked in a pipe, absorbed rapidly in the lungs and reaching the brain in about 5 seconds. Effects of cocaine is sport It was misused in sport due to its euphoric effect and due to reduction of fatigue. Side effects Its side effects are: tachycardia, hypertension and at high dosage, tremors and seizures may occur. Cardiotoxic metabolite may result due to concomitant use of cocaine with alcohol and anabolic steroids. Reported cases of cocaine misuse Len Bias, the US basketball player, and Don Rogers, the American footballer died from cocaine abuse.(1) Caffeine Caffeine is the most popular used drug which is found in many beverages like coffee, tea and soft drinks. Caffeine was banned by IOC but then it was withdrawn from the list by WADA in January 2004. However, its use is still monitored by WADA. Quantitative measurement for caffeine in the urine was established in 1984 at the Olympic Games in Sarajevo and Los Angeles. IOC set the level in the urine at 15 micrograms per millilitre and then in 1988, it was decreased to 12micrograms per millilitre. Studies showed that 1000mg doses of caffeine are required to excrete caffeine in the urine at levels more than 12 micrograms per millilitre. Routes of administration It is taken as tablets or injections(1) Effects of caffeine in sport High doses are required in sport to decrease fatigue and increase concentration.(1) Side effects tremors Narcotic analgesics These are called opiates. Raw opium contains morphine and codeine which have strong analgesic properties. Drugs that are usually misused are: Morphine, heroin, and methadone. All opiates were banned by IOC except dextromethorphan, pholcodeine, and diphenoxylate. Codeine was first banned but because many sports federation had refused that so it was then removed from the list due to its presence in many over-the-counter medications. Mechanism of action: Opiates bind to specific opiate receptors in the brain and spinal cord, and also interact with endogenous opiate peptides, enkephalins and endorphins, in mediating emotional highs and in the process of addiction.p(1)-23 Routes of administration Opiates are taken orally, by injection or by inhalation. Effects of narcotic analgesics in sport These are used for their euphoric and analgesic actions. They are used to mimic the injury during training or competition. Side effects These include vomiting, diarrhea, dry mouth, skin itching, loss of concentration, drowsiness, comas, and addiction. At high doses it may cause respiratory depression.(1) p24,,BBC Diuretics and other masking agents Diuretics are drugs that are used by people to remove fluid in order to decrease blood pressure. Examples are: furesamide, acetazolamide and chlorthalidone. Effects of diuretics in sport Diuretics are misused in sport to overcome the side effect fluid retention that is cause by athletes misusing anabolic steroids. They are also used to lower the athlete’s weight in sports that competition occurs in weight groups. P46red and BBC. Also diuretics are used to increase the flow of urine and hence increase the rate of excretion of abused drug or its metabolite in the urine so the abused drug could not be detected. Side effects These include: muscle cramps, dehydration, headache, nausea and kidney damage. Probenecid is used as making agent to disguise the presence of banned drugs and their metabolites by inhibiting the excretion of these through the kidney.p47 red. Probenecid is no more used because the use of gas chromatography and mass spectrometry can detect its presence and catch up the cheats. Beta blockers These were added to the list of doping classes in 1985. But because of its therapeutic use, the IOC in 1993 added them in the â€Å"classes of drugs subject to certain restrictions â€Å"part . They were used by athletes to increase their performance by increasing the cardiac output increasing blood flow to muscles.p-48-49 red Peptide and glycoprotein hormones These are natural substance that are produced by the body.BBC –doping I sport Effects in sport Corticotrophin: it induces the release of the adrenal corticosteroids thus mimic the pain after injury. (1)p47 Human Growth hormone(HGH) and chorionic gonadotrophin( HCG) : it has anabolic effect, so it increases size and strength of muscles. BBc Erythropoietin: it is a peptide hormonep48(1). It increases red blood cell production thus increasing the oxygen transfer by blood ,ie. Increase in the performance .BBC. Side effects HGH has main side effect that is, it may cause acromegaly.BBC EPO has main side effect that is, it may thicken the blood, resulting in heart attacks.BBC Chemical and physical manipulation It is the changing of urine sample by using substances or procedures in order to conceal the detection of a banned substance. Examples of manipulation are: the use of other’s urine, use of vinegar to affect the urine, epitestosterone to alter the ratio. BBC news,doping Anabolic Steroids What are Anabolic steroids? Testosterone was isolated in 1935.(2)p52. It is an endogenous steroidal hormone male hormone produced by testes in men. steroid 7. It is synthesized from cholesterol like all other steroidal hormones. Steroid 7. Epitestosterone is a testosterone isomer and found in a small ratio with respect to testosterone. Steroid7. Testosterone is responsible for the androgenic and anabolic effects.steroid7. The androgenic functions of testosterone are responsible for the modifications in the primary sexual male features. Steroid7. , while the anabolic effects are responsible for enhancing muscle growth, protein synthesis and erythrocytes. steroid 7. Anabolic steroids are group of synthetic modified derivatives of testosterone. steoid 10. When administered, they bind to the androgen receptors which are found in the prostate, skeletal muscle and central nervous system to give their mechanism of action. Their structure is developed and modified to improve the anabolic effects with decreased androgenic effects. steroid 10 Routes of administration Anabolic steroids are administered orally or intramuscularly. Nowadays, athletes are using transdermal patches, sublingual tablets, nasal sprays, and dermatological gels of testosterone to escape positive tests(2). P 3 Why do athletes misuse anabolic steroids Athletes use anabolic steroids due to their anabolic effects, so they are used due to its positive effect on the skeletal muscle tissues. They are used to increase strength and muscle size. They are also used to increase body weight, protein metabolism and collagen synthesis. Steoird 6 and 35 . Some athletes use anabolic steroids because they â€Å"want to be big†. steroid 7. Side effects Cardiovascular effects: Anabolic steroids ingestion results in severe coronary heart disease. They reduce high density lipoprotein (HDL) and increase low density lipoprotein (LDL). Steroid 25- steroid 7. resulting in atherosclerosis. Increase heart stroke Anabolic steroids increase blood clotting and thus favouring thrombosis resulting in heart attacks. steroid 26 Liver problems Oral anabolic steroids results in cholestatic hepatitis and jaundice. steorid 7,26 Also increase in the liver enzymes( aspartate amino transferase, alanine amino transferase and lactate dehydrogenase) is encountered with the use of steroids. steroid 37 Sexual side effects High doses of anabolics in a study by Holma, shows that the sperm counts decreased by 73% and azoospermia occurred for 3 individuals i.e affecting fertility. Steroid 7 They affect secretion of the reproductive hormones like testosterone and thus reducing libido due to decrease level of luteinizing hormone (LH) and follicle stimulating hormone(FSH).sterodi 37. Anabolic steroids abuse may result in prostate cancer. Steroid 37 Gynaecomastia It is the enlargement of the mammary tissues in men due to transfer of androgens to estradiol and estrone. steroid 7,37 Psychological effects A study in USA showed that anabolic steroids revealed changes in mood such as mania and depression. steorid7 Other side effects include: hyperinsulinemia, hypertension, tendon damage, steroid 26. edema, muscle spasm, acne hirsutism, and deepening of voice. Steroid 35 History of anabolic steroids misuse and drug testing The use of banned substances such as caffeine, cocaine and strychnine started during the 19th century in most of the sport events like cycling, swimming, and distance running. steroid 26. The abuse of steroids in sport started in 1950s by the soviet weightlifting teams.p54 green,steroid26. In 1960 Olympic Games, anabolic steroids use was restricted to Soviet weightlifting, but by 1964, their use is increased in all strength sports. p45 green. 7. Anabolics use became more common in most sports in 1972 Olympic Games. Steroid 26 Anabolic steroids use has been banned by medical commission of IOC in 1974 and has been added to the list of banned substances of IOC in 1975.steroid 10, 7 Although the first formal testing was introduced in 1972 Munich Olympics, there was no testing for anabolic steroids (7). P4. The first formal test for anabolic steroid was in 1976 Montreal Summer Olympics(7). First positive tests for steroids were in 1976 Montreal Olympics, in which 8 athletes, seven weightlifters and one female athlete in a field event were caught for steroid abuse(7).p75., while no positive tests were reported in 1980 Moscow Olympic Games. Anabolic androgenic steroids are one of the most widely used drugs by athletes to enhance their performance and physical appearance. Steroid 6. Their use extends to be not among professional athletes but also among high school male and female students. Steroid 26 WADA accredited laboratories published statistics form 1993 till 2003 and this showed that anabolic steroids are the most widely used banned substances.p32.red. 1993 1994 2001 2002 2003 stimulants 22.8% 24% 15.4% 14.9% 19% Anabolic steroids 59.9% 50.5% 40.1% 36.8% 32.1% Unlike amphetamines and other stimulants which were taken on the day of competition ( which causes sudden death due to cardiac arrest), anabolic steroids are administered during the training exercise and not before the competition periods. P31 red. they are taken in cycles with duration of six- twelve weeks, and usually 2-3 cycles are taken in a year. Steroid7. The introduction of the â€Å"out of competition† testing programmes limited the use of the anabolic steroids. P46 red Systematic doping: biggest scandal One of the biggest scandals for steroid abuse was in the German Democratic Republic, they were used from 1965 to 1989 and this allows the East German to win many medals. Coaches and doctors in East Germany follow a programme for systematic doping with steroids. In 1965, a pharmaceutical company had developed chlor-substituted derivative of methandrostenolone (Oral-Turbinabol R), and from 1968 GRD started to introduce it to female athletes in the Olympic Games. Steroid 40 Detection of anabolic steroids: Detection of urinary anabolic steroid by radioimmunoassay Drug testing was based on radioimmunoassay screening of urine samples from athletes for detection of banned substances and then gas chromatography/mass spectrometry for confirmation the positive tests (7). Testing at that time was insensitive and not selective due to the fact that testing was done during competition periods and anabolic steroids were usually taken for long periods, so athletes used to quit these drugs at competition periods so their level will decrease in the urine and could not be detected and the tests would give false negative (19). Detection of urinary anabolic steroids by GC/MS, measuring testosterone to epitestosterone (T/E ratio) Drug testing at that time could not differentiate between endogenous testosterone and synthetic anabolics.steroid7. Testosterone was introduced in the banned list of IOC in 1983, it was the first endogenous substance to be banned, after the discovery of the detection method in 1982. p35red. In 1984 Olympic Games, all urine samples from athletes were screened by GC/MS for detection and identification. The T/E ra
