Effects of divorce on children - Essay Example It is obvious that no parent likes to experience the divorce, so why would they want their child do experience it Regretfully, divorce is quite common in present-day society, but researchers have proved that there is a negative impact on the children and their future. A lot of children do not recover from a divorce and their inability to cope with it affects their relationships later on. When parents decide that they will have a divorce, it is not in happiness as most children seem to feel. A recently divorce man/woman will feel a loss concerning their spouse and their marriage. There is also a sense of relief that the faade is over and they can start healing themselves against the pain and suffering they were going through. For those people that do not have children is easier to avoid each other as they will have no strings attached and are in a sense 'free', but those with children need to adjust to their setting quickly and then help their children with the process and help them understand the reason so there are not negative effects of feelings. With or without the divorce, almost all parents want their child to do well but research again shows that children from divorced family do worse, some of them repeat a grade and have a 5% more chance of being expelled. Younger children become more dependent, demanding, unaffectionate and disobedient than children from patched families. They are terrified of being left alone or being unloved, therefore carrying these problems with them to school as well as start using drugs, get into violence, try to commit suicide and have children out of wedlock. Some children believe that they are the source of the divorce because of their misbehavior, due to which children just shut down and keep their feelings to themselves, losing the friends they have and creating a shell around them that doesn't let anyone in. Some effects of children in divorced families are: Being poor Problems in school - lower grades, being held back, dropping out Poor health Higher probability of abuse, mental illness, criminal behavior and early sexual activity Feeling of loss over one parent's absence due to divorce Risk of being abused Impulsive and impatient behavior Anger at others Oppositional, rebellious, defiant, or conduct problems Breaking rules and testing limits Destructive behavior Anger at self Self-blame or guilt Self-destructive or self-harming behavior Apathy or failure to accept responsibility Isolation and Withdrawal Becoming divorced themselves someday Yearly, over 1 million American children experience the tragedy of divorce, and half the children that are born within the year will have parents who will divorce before they turn 18. American society has to teach it citizens that marriage is the best surroundings in which to raise healthy, happy children who reach their potential and family is the essential item for a social well-being. The best thing that parents can do for their child while the divorce is to assure them that the divorce is not the child's fault and to tell them constantly assure them that they are loved by both parents and the relationship with either parent will not be

Severn Suzuki Article Essay Example for Free

Severn Suzuki Article Essay WE are responsible for our Planet Our planet Is getting more and more dirty. The earth Is full of waste and the temperature Is getting higher and higher. Would n It be nice to live on a clean and comfortable planet, where you can feel the nature with all its beatiful sections. Earth Summit, that is the name of a UN conference in 1992 met in Rio de Janeiro to consider the urgent need for development in developing countries. They are planning, not to destroy the ability of future generations to meet their own needs. Earth Summit wants all people to fix the lifestyle, maybe only a little bit, and save the orld. A girl named Severn Suzuki paid for the trip to Rio herself and wanted to let people think about our Situation with the earth and talked In a public speech to all people. She wants to change the habits of adults and children. Severn says, that she found fish with cancer. Is this the way we want to eat fish? We really have to think of what we can make better in waste seperation. So if for instance plastic is thrown in the sea, the fish will eat the plastic, and we eat the fish. Horrible! Another problem is the buying of unnecessary things. We buy and throw away. Why don t we think of what we really need? In my oplnlon the arguments from Severn Suzuki are still a big problem nowadays. Actually the problems got worse. If the society does not change their lifestyles, maybe we are all killer. Because we killed our children or grandchildren. Firstly the production of plastic and other nonbiodegradable waste increases. And secondly the waste seperation is not important for the people any more, because they do not realize the danger. To sum up we all have to work and clean our planet, f we want to live on the beatlful earth. We can not only use and use and giving nothing back to regenerate, so It Is on our planet.

Negative Aspects of IT on Social Communication

Negative Aspects of IT on Social Communication M2 Abuse of IT Now create additional blog pages that discuss the negative aspects of IT on social communication give examples and explanations using the headings underlined below please use your OWN words. Abuse of IT: Threats: This can range from hacking into someones computer to sending scamming emails designed to gather personal information. In many cases corporations and sell personal information for as little as 1p per person. This blog will explain different types of IT abuse and show examples of different real life situations. Cyber Bullying: This is the act of bullying or abusing a person using electronic devices such as a mobile phone, computers and tablets. Examples of cyberbullying include mean text messages or emails, rumors sent by email or posted on social networking sites, and embarrassing pictures, videos, websites, or fake profiles. One of the main problems with cyber bullying is the fact that it is consistent. Texts, emails and social network posts can be sent and uploaded at any time meaning the person be bullied cannot get away. With verbal and physical bullying the person can get away from it, buy staying in their home but cyber bullying is a consistent form of torture. One of the cyberbullying contenders is social networking sites like Facebook and Twitter. Once something is posted, it can be nearly impossible to remove as other people can screenshot it and then they will have it on their hard drive and can no longer be deleted. Cyberbullying has many effects on the person being bullied, these include: Drinking alcohol and using drugs Skipping school to avoid contact with the people bullying them Have lower self-esteem and get poor grades because of it Could lead to mental health problems In some cases, cyberbullying can lead to suicide. Cyberbullying has claimed many lives, such as the life of Hannah Smith 1999-2013. She was a 14-year old girl from lutterworth, Leicestershire, England, hanged herself in her bedroom on August 3rd, 2013. This is one of many cases in that people have ended their lives because of other people. The story tells us that this is a serious subject any should be reported instantly. Because people do not talk about it often ends badly but if you talk to someone it can, will be sorted, and can lead the bully in jail. https://www.stopbullying.gov/cyberbullying/what-is-it/ Spam: Spam is a form of advertising that you will receive unwillingly. This happen because at some point you gave your email address away on online forums, new groups etc. A spam email contains fake information and links that ask for Credit or Debit card information and personal information. Spam emails also come as a phishing email that disguise themselves as banks. They do this to get access to card details to take money out of your bank account. Spam is typically used to promote inexpensive pharmaceutical drugs, weight loss programs, job opportunities and online gambling.   These can lead to lose of personal information that companies can sell on so more people get access to your personal information and then you will receive more spam and fraudulent emails. Botnets is an example of a spamming technique used to command-and-control servers which collect email addresses and distribute spam emails. There are many warnings and news reports about fraud emails. There is a case of fake speeding ticket from Manchester. The police warned the public about the scam aimed at stealing bank details from businesses across the country. The email would invite people to click on a link that shows photographic evidence of the offence. http://searchsecurity.techtarget.com/definition/spam http://www.stokesentinel.co.uk/warning-about-bogus-8216-speeding-ticket-8217-email-claiming-to-be-from-greater-manchester-police-scam/story-29978636-detail/story.html Phishing: Phishing is a form of fraud in which the attacker tries to learn information such as login credentials or account information. Phishing emails can disguise themselves as official emails from banks to try to gather bankcard details to use. They send you to a fake copy of the official website. There is a large variety of new reports about phishing emails. There is a news report on the Mirror website about fraudsters send out fake court summons that when opened give the computer the virus called The Trojan Horse. This virus give the sender complete control over the computer from anywhere in the world and gives then access to a large amount of personal information. In another case, a man was jailed for a phishing fraud that was sent out to UK students to try to steal  £1.5m. Olajide Onikoyi, 29, of Hexagon Close, Blackley, Manchester, sent out emails asking them to update details on their students loans. He stole  £393,000 from 283 victims in total before he was caught. Phishing emails are as effective as they are http://searchsecurity.techtarget.com/definition/phishing http://www.mirror.co.uk/news/technology-science/technology/beware-cyber-fraudsters-sending-out-3114925 Denial of Service Attacks: This is a method of preventing a web server from providing a service by overwhelming it with so many requests that it is unable to cope. An example of this is that a criminal might try to blackmail a company by threatening to attack their website unless the company gives them money. In some cases, political websites are attacked as the attacker does not agree with the political view. Identity Theft: This is the fraudulent use of using other peoples names and personal information to gain access to loans, credit card numbers and other relevant information. This allows the thief to possibly take out loans and buy multiple items in your name which will cause problems for you as you could end up in debt. Gerald Barnbaum lost his pharmacist license after committing Medicaid fraud. He stole the identity of Dr. Gerald Barnes and practiced medicine under his name. A type 1 diabetic died under his care. Dr. Barnes even worked as a staff physician for a center that gave exams to FBI agents. Hes currently serving hard time. In this case the consequences were rather extreme however there are more extreme cases out there. The reported cases show us that this is a serious problem as unqualified people are pretending to be Doctors and other trained staff. http://www.huffingtonpost.com/robert-siciliano/10-unbelievable-identity_b_5239159.html Bibliography: https://www.stopbullying.gov/cyberbullying/what-is-it/ http://searchsecurity.techtarget.com/definition/spam http://www.stokesentinel.co.uk/warning-about-bogus-8216-speeding-ticket-8217-email-claiming-to-be-from-greater-manchester-police-scam/story-29978636-detail/story.html http://searchsecurity.techtarget.com/definition/phishing http://www.mirror.co.uk/news/technology-science/technology/beware-cyber-fraudsters-sending-out-3114925 http://www.huffingtonpost.com/robert-siciliano/10-unbelievable-identity_b_5239159.html

Abortion: Different Sides :: Essays Papers

Abortion: Different Sides When the topic of abortion is brought up, many people have different opinions. The only way we can have a sense of how the situation feels and the circumstances are from someone who has experienced it themselves; the mother. Here is a true story from Becca and her fight for life: â€Å"I write to you as an abortion survivor. My mother went to a clinic at 22weeks to get rid of me, most were appalled that she waited so long. Well to make a long story short they gave her the saline solution...or gave it to me rather. I was burned and poisoned but it didn't kill me. She never went into labor and so she figured she had to carry me to term but it didn't matter. I was dead or so she thought. 25 weeks came and went [†¦] she felt me still kicking. So she went back, the doc found me still breathing and he offered a partial birth abortion. My mom said she needed to think on that one and so we went back home. At thirty weeks, she never went back and she was starting to wonder about me, wa s I even still alive? I wasn't kicking as much anymore. Well she went into labor at 35 weeks, average gestation and all. I was born, my skin was red and scarred, my hair was gone and I was blind...the salt solution burned my eyes. The nurses were mortified from what my mom tells me, said I looked like Freddy Kruger. I had to have a lung transplant because my right lung was too burned up to function right. I was taken home, eventually my scars cleared up but I never got my sight back. I'm glad in a way that I couldn't see, after what my mom had done to me I could never look her in the eye anyway and hold back the contempt. Time passed, I'm 22 and married with a sweet baby of my own. My son Tristan came to me on February 27, 2002 and was perfectly healthy. I have also had surgery on my eyes, my vision is blurry but I can see a world my mother never intended me to see (abortionTV). For more stories and cases, go to Abortion Stories. This story shows us how one instance can ruin someone ’s life and also turn it into a blessing.

Religious Allusions and Metaphorsâ€Martin Luther King Jr Essay

Martin Luther King, Jr., in his famous Letter from the Birmingham Jail, responds forcefully yet politely to a public statement made by eight Alabama clergymen in 1963. He defends his position as an African American and strongly defends racial equality, referencing countless sources and utilizing several literary devices. Most significantly, King uses frequent Biblical allusions and metaphors, not only to relate to the Clergymen and the people of Alabama, but also to display his passion for equality. For instance, when he speaks of just and unjust laws, he references the reasoning of Saint Thomas Aquinas, â€Å"To put in the words of Saint Thomas Aquinas, an unjust law is a human law that is not rooted in eternal and natural law. Any law that uplifts human personality is just. Any laws that degrades human personality is unjust†(King 180). King cites the book of Daniel when he discusses Shadrach, Meshach, and Abednego and the disobedience of a law for higher moral principle. King also relates himself to the Apostle Paul and his thriving effort to assist the men and women who call for his aid. After much further research I have gained new insight in why King used these metaphors as he did. Outside sources have helped me analyze the deeper meaning behind the allusions and understand the changes King was hoping to impose on the public and the Clergymen. King’s ideals are supported with his immense knowledge of the Bible, which make his connections extremely credible. King opens his letter by connecting himself with the Apostle Paul in an attempt to better associate with the Clergymen. â€Å"Just as the prophets of the eighth century B.C. left their villages and carried their â€Å"thus saith the Lord† far beyond the boundaries of their home towns, and just as the Apostle Paul left his village of Tarsus and carried the gospel of Jesus Christ to the far corners of the Greco-Roman world, so am I† (King 174). Upon first read of the â€Å"Letter† I clearly thought that King was using Biblical references simply to relate to the Clergymen on a level they could understand. Though King is, in a sense, trying to establish his credibility by using this allusion, there is a much more clandestine meaning. â€Å"Like The prophets of the eighth century and like St. Paul, King must leave home and respond to the call for aid† (Tiefenbrun 265). After researching Paul, I found why King used him in his letter. Paul was persecuted for spreading  Christianity. So much so that he was put in prison. While in prison he, like King, wrote many letters responding to the criticism he was receiving. Some of these letters were encouragement to the Christians of Corinth and later became the book of Corinthians in the Bible. Paul died as a martyr, fighting for his beliefs just as King did. Paul’s mention was an early warning to the Clergymen of what they were doing to King. If they continued their criticism and persecution, King will end up facing a grim future. At first read I thought King was only addressing the Clergymen as a response to their letter, but with further research I have uncovered an indirect public statement. In the Letter from Birmingham Jail, King discusses the story of Shadrach, Meshach, and Abednego, praising their act of civil disobedience. He states, â€Å"It was evidenced sublimely in the refusal of Shadrach, Meshach and Abednego to obey the laws of Nebuchadnezzar, on the ground that a higher moral law was at stake. It was practiced superbly by the early Christians, who were willing to face hungry lions and the excruciating pain of chopping blocks rather than submit to certain unjust laws of the Roman Empire† (King 180). In this statement King is reaching out the general public, encouraging them not to conform to a â€Å"false idol† of society. † Kings Biblical reference to Shadrach, Meshach, and Abednego creates an identity between the Alabama demonstrators’ form of civil disobedience and â€Å"the refusal of Shadrach, Meshach, and Abednego to obey the laws of Nebuchadnezzar, on the ground that a higher moral law was at sake† (Tiefenbrun 263). King uses Shadrach, Meshach, and Abednego to correlate his ideas of what a society could be not only to the ignorant people of Alabama but also to everyone willing to listen. Martin Luther King Jr. handpicked these events in Biblical history to more clearly represent what he is writing about and why he is so avidly defending his cause. He argues against repression and urges the public to defend their rights and resist the rut of conformity. Just reading Letter from Birmingham Jail won’t do it justice. Further researching the components of this letter have opened my eyes to what King was really portraying. King is pleading with the Clergymen to reconsider their prejudice against him and his beliefs. He is driving the public to become like him, and to become like  Paul stating that it is ok to be persecuted for your beliefs. He makes clear in hismessage that it will not be an easy task but it must be done in order to create an influential change in society. This change must be done now so that it can display its longstanding effects on the generations to come. Works Cited King, Martin Luther Jr. â€Å"Letter from Birmingham Jail.† A World of Ideas. Comp.

Developments In Direct Reduced Iron

Developments In Direct Reduced Iron ( DRI )Direct reduced Fe ( DRI ) is produced through the solid province decrease of Fe oxides derived from Fe ore or electric discharge furnace ( EAF ) mulcts for the usage as a virgin Fe beginning in the EAF or basic O furnace ( BOF ) processes. Virgin Fe beginnings are needed in the EAF procedure to thin the remainders ( Cu, Ni, Cr, Mo, or Va ) nowadays from old steel doing operations in the bit steel used as the primary natural stuff used in the EAF. DRI is produced in many different procedures utilizing several different fuels and different provender stocks. The DRI processes use several reaction vass including shaft furnaces, rotary fireplace furnaces, fluidized bed reactors, traveling bed reactors, and rotary kilns. The fuels used in the procedures are chiefly coal or natural gas, these fuels are used to make a reduction ambiance and elevated temperature to make a more favourable reaction. The quality of the DRI is measured by the sum of meta llic Fe ( Fe or Fe3C ) is present in the merchandise. This figure is called metallization and is reported in a per centum of the entire mass of the merchandise. The merchandises of the DRI procedures are either pelletized into DRI or briquetted into hot briquetted Fe ( HBI ) . The decrease of the Fe ore or EAF mulcts takes topographic point in several reactions that cut down the Fe oxides to metallic Fe ( eq. 1 and 2 ) . The reduction gases are produced by burning natural gas or a C beginning so adding the heated burning merchandises to the reaction vass. Fe2O3 + 3H2 ( g ) > 2Fe + 3H2O ( combining weight. 1 ) Fe2O3 + 3CO ( g ) > 2Fe + 3CO2 ( combining weight. 2 ) Hydrogen and C monoxide are formed from burning natural gas, while merely C monoxide is formed when coal or coke is combusted. The difference between the procedures is how the provender stock is exposed to the burning gases. The most common type of reaction vas is the shaft furnace where the provender stock is fed into the top of the furnace so dropped through the vas to be exposed to the reduction gasses so extracted from the underside of the furnace. The conceiver of utilizing the shaft furnace for DRI production is the Midrex corporation and is known as the Midrex Process. The Midrex procedure uses a Reformed natural gas as the decrease gas and requires the usage of pelletized Fe ore as a provender stock. The natural gas is combusted in a reforming vas so fed into the shaft furnace where it is assorted with extra natural gas and O to make some more chemical energy for the procedure ( figure 1 ) . The fluke gas is so fed through a station burning chamber and the energy extracted from station burning is used to preheat the provender gas. This gas is so fed to a bag house where it is scrubbed before being reintroduced to the ambiance. This procedure creates chiefly DRI pellets due to the provender stock being pelletized Fe ore and at that place non being a demand to alter the geometry through briquetting. A mistake of the Midrex procedure is its dependance on pelletized ore. The procedure requires the provender stock to incorporate no more than 3 % mulcts. The DRI pellets produced have a high metallization of 95 % on norm, doing it the highest quality DRI. The usage of the station burning allows the Midrex procedure to derive the bulk of the available energy and is what has made it favourable for the bulk of world-wide DRI production A faster production method and 1 that has more flexibleness than the shaft furnace is the rotary fireplace furnace or the Fastmet procedure. The rotary fireplace furnace is a uninterrupted operation that feeds stuff into a revolving furnace that passes the stuff through the reduction atmosphere so removes the stuff near when it completes the full rotary motion ( figure 2 ) . Unlike the Midrex procedure the Fastmet procedure uses mulcts as a feedstock. This allows for the recycling of EAF mulcts and mill dust that would be otherwise disposed of as a risky stuff. The Fastmet procedure uses a C cut downing agent and O burners. The C can be from legion beginnings such as coal, C bearing wastes, and coke. The procedure is seldom run utilizing coke due to the high cost of the coke and the procedure being capable of running on lower quality C mixes. The procedure requires a pelletizing or a briquetting operation due to the provender stock being mulcts. The full procedure requires between si x and twelve proceedingss to finish. The rotary fireplace furnaces produce a direct reduced Fe with a metallization runing from 85-92 % depending on the quality of the provender stock. Fluidized bed reactors are a batch reactor that introduces the stuff into the reactor so the reduction gasses are fed into the underside of the vas with adequate force per unit area to drift the provender stuff. This natation of the provender stuff allows for all of the surface country of the stuff to be exposed to the reduction gasses. There are several signifiers of fluidized bed reactors being used in the market today. The difference between the reacting vass is the figure of responding vass and the type of fuel used to making the reduction gases. The first type of fluid bed reactor is the Finmet procedure using Fe ore mulcts or EAF dust as a provender stuff and natural gas as a cut downing fuel. This procedure uses up to a four phase reactor with the progressive phases utilizing a higher gas speed and a lower reaction clip to derive between 91 % and 93 % metallization ( figure 3 ) . The Finmet procedure requires a briquetting operation because the provender stock is mulcts but be cause of necessitating a high pureness natural gas fuel it produces a really low residuary HBI. The following two procedures, Circofer and Circored, both feature a two phase fluidized bed reactor with the first phase being a short keeping clip vas with a high gas speed and the 2nd phase a long keeping clip with a low gas speed ( figure 4 ) . The difference between the two is that the Circofer procedure uses metallurgical coal for a fuel while the Circored procedure uses natural gas. Both of these reach an mean 92 % metallization and provender pellets. Hsysla steel developed a traveling bed reactor to make DRI ( figure 5 ) . The Hyl procedure provenders lump Fe into the procedure and a high H content reformed natural gas. The high H is created by reforming with a nickle-based accelerator. The Hyl procedure uses an elevated temperature and force per unit area to increase the processing clip for the reactions. The high H and the elevated temperature and force per unit area create a high quality DRI with 93 % mean metallization. The concluding reactor vas is the Allis Chalmers controlled Atmosphere Reactor ( ACCAR ) . The ACCAR uses a counter flow rotary kiln. The rotary kiln procedure uses a low quality but extremely reactive coal to make cut downing gasses ( figure 6 ) . The rotary kiln produces a DRI with a 92 % metallization. The responding vas does non use any of the station burning in the procedure but station burning vass have been added to the procedure to make adequate energy to power the full installation and add some back to the grid. With DRI being produced in many different treating methods there are some cardinal characteristics that set some appart from the others. The rotary kiln, shaft furnace, and the traveling bed reactor vass produce the highest metallization. The rotary fireplace furnace has the fastest procedure clip. The most popular on the market right now is the Midrex shaft furnace with about 60 % of the market portion of DRI production ( table 1 ) . DRI is a stuff that EAF operations have come to depend on and will go on to increase usage due to the high cost of hog Fe and the continued recycling of bit steel.Table 1 ) Comparative sum-up of procedures as of 2008World Production Reactor Feed Type Reducing agent Average metallization Merchandises ACCAR 24.0 % Rotary Kiln pellets Low quality Coal 92 % Pellets and Energy FinMet 2.0 % Fluid bed reactor ore mulcts natural gas 91-93 % Briquettes Hyl 14.5 % Traveling bed reactor ball ore Coal 93 % Pellets or briquettes Midrex 58.2 % Shaft pellets natural gas 95 % Pellets Circofer 0.5 % two stage fluid bed ore mulcts Coal 92 % Pellets or briquettes Circored 0.5 % two stage fluid bed ore mulcts natural gas 92 % Pellets or briquettes Fastmet 0.4 % Rotary fireplace EAF dust/scrap Carbon 85-92 % BriquettesPlants CitedBresser, W. , & A ; Weber, P.

Situation analysis coca cola essays

Situation analysis coca cola essays More and more people worldwide have to deal with obesity these days. This is increase in obesity is probably caused by a change in behaviour of food and beverage consumption. Nowadays, we eat and drink faster and more, because of the fact that we can eat and drink everywhere, anytime. Vending machines, fast food restaurants, take away restaurants, etc. are all examples of the fact that food is everywhere. We also have less time to eat together with our family members and make time for healthy cooking, many people buy ready-made or instant products. Obesity is not only caused by consumption of an increased amount of calories, but also by a decreased amount of body-exercise, physical activity and sports. People have more and more desk jobs, less time to join a sports club, children play more on their computer instead of outside, more than 80% of the parents bring their children to school by car, etc. Experts agreed upon the cause of obesity, a combination of what is stated above; a chronicle imbalance between the number of calories consumed and the number of calories used.. People gain more weight if they eat more calories than they burn. Some people are in action a whole day, so that their metabolism is running at full capacity. Others sit at a desk to work, take the car for every movement and like to watch TV at night, they are less lucky. We will have to make important choices: eat healthier, do more exercise or a little bit of both of them. The main problem is that our energy equilibrium is off-balance! A measurement for overweight that is used worldwide is the BMI , when this ratio is between 25 and 29.9, we talk of overweight and if it is more than 30, we talk of obesity. At this moment, there are an estimated 300 million obese adults worldwide (BMI>30), up from 200 million in 1995. 700 million more are overweight (25

All My Sons2 essays

All My Sons2 essays All My Sons, a play by Arthur Miller, tells predominantly of the story of the Kellers. This play takes place after World War II, in the year 1947. It is a drama of actions and consequences and morality. This theme of actions and consequences is shown after Joe Keller ships out defective engine parts, which ultimately ends in the death of many pilots including that of his own son, Larry Keller, who kills himself in shame of his father s actions. Joe Keller had two sons, Chris and Larry, who is dead. Chris and his father, Joe, have opposing morals and viewpoints on many of the issues that govern their lives, primarily the issue of the shipment of the defective engine parts. Chriss criticism of Joe and his morals in juxtaposition to his own produces a revelation of Chriss true character and his character flaws. Chriss main criticisms of Joe, his father, chiefly deals with the shipment of the defective engine parts. Joe plays a major role in this play. He is shown as the antagonist, the one who through his bad decisions, ends up killing many innocent pilots who were only defending their country. In All My Sons, Miller complicates the story in that the father becomes flawed morally to such an extent that the outside forces function as reflections or testimonies of the essential inner weakness. (Martin, 9) As Yorks shows in his essay, through Joes loyalty to his business and his family, Joe betrays the larger loyalties of the global conflict [World War II] (21) by shipping out defective engine parts. Joe tries to defend his actions by saying, Who worked for nothin in that war? When they work for nothin, Ill work for nothin...its dollars and cents, nickels and dimes; war and peace, its nickels and dimes, whats clean? Half the Goddamn country is gotta go if I go! (Miller, 67) Joe claims to Chris that almost all the businesses inv...

Leadership Essay Example | Topics and Well Written Essays - 1000 words - 17

Leadership - Essay Example In our daily life, we often play the role of a leader whether or not we realize this. In this paper, I have analyzed my own style of leadership that prevails in a particular context. This paper first describes the scenario in which I have analyzed my style of leadership followed by a comprehensive discussion of the identified style of leadership. I used to play in a rock band as a lead guitarist. There were five members in my group. We used to record songs and I used to take active part in that activity. I used to tell my group members my opinions regarding the songs as well as their lyrics. Since our group also made songs, and I have good sense of poetry, I helped my group write the lyrics of the songs. Even now when my friends make a new song and record it, the first person they send its copy for a review and necessary alteration is me. This is because they believe in my abilities as a lyricist and trust me that I would give them honest advice. When I give advice, they change the songs accordingly. In the situation described above in which I help my friends in writing the lyrics of the songs or help them modify the lyrics they have written to make the songs perfect, I play the role of a servant leader. Robert Greenleaf coined the term â€Å"servant leader† in the 1970’s. Servant leader is a person that may not necessarily be formally identified as a leader. When an individual working at any level in an organization leads just by addressing the needs of the team, that person essentially plays the role of a servant leader. In my case, I used to meet the needs of my friends by giving them useful advice regarding their songs. Although by doing so, I helped them yet I was never recognized as a leader perhaps because I was their age and a friend to them. This made me their servant leader. A servant leader resembles a democratic leader in many ways since in such a leadership, the whole team plays a role in the decision-making. In my case, when I

Policies to Reduce Unemployment Essay Example | Topics and Well Written Essays - 2500 words

Policies to Reduce Unemployment - Essay Example It's with this in mind that the government of the UK has to change tactic in order to enable companies to remain in business and create job opportunities despite the economic recession The number of people in full time employment fell drastically between 2007 and 2009 (Arnold 2001). The rate of loosing jobs is alarming. About the same number of jobs lost the previous year were lost in just four months last year from October 2008 to the beginning of the year 2009. it better to make the assumption that those who lost their jobs were those who were being paid well from their professional expertise and could still be living on their bonuses. The number of people unemployed but actively seeking employment has increased by about one million, other people appears to have opted for part time jobs and as a result the number of part-time employees has increased by almost 1.3 million. Some people have already given up (Gilbody 1998). By the beginning of the new millennium, (the year 2000) the world was very different from the way it was in the 1900s. The United Kingdom underwent a massive change. The labour party of United Kingdom had won its second term to serve again in office. In the beginning of the year 2001, the government wanted to have enough money to be spent on public services especially the national health services which was being under funded by then (Arnold 2001). The economic growth rates have been quite stable operating at about 2-3% since the beginning of the millennium. Inflation has not been a problem to the economy of the British government. The bank of England has been able to regulate the interest rates therefore managing to stabilize the economy of Britain. The pound has maintained a stable increase in value reaching a minimum rate of 1.37 dollars against the US dollar in 2001 and rising again to about a rate of one pound going for two dollars (Arnold 2001). With the emergence of the current economic recession, the number of people loosing jobs has caused a serious setback or rather it's an impediment to the banks lending, prevention of debt deflation strategies to be implemented and to renew output growth (Gilbody 1998). There has also been a wave of rising defaults all concentrating in the riskier parts of the banks loaning documents; buy to let loans, subprine mortgages and lending money to private equity enterprise as well as the management of financial asset acquisition among other activities, Europa Publications Staff (2003). Intervention to Support Economy It's very correct to stick to the conventional parts of lending schemes as advised by senior bankers since they have been performing well till now. The problems have only emerged on the financing side of bank's balance sheets and other particular aspects of the lending side. In other parts, the process of risk management on the ability to lend has performed convincingly fine. The amount of loss encountered rose in regions where systems for management of risks and credit control schemes are purposively overridden by senior managers anxious to take over the market share or produce mortgages for the packaging as a section of the model known as

Analysis Of My Antonia Essay Example | Topics and Well Written Essays - 750 words

Analysis Of My Antonia - Essay Example But as the story progresses and he comes to understand the reality of the situation, he shows his appreciation for immigrants like Antonia by stating –‘One result of this family solidarity was that the foreign farmers in our county were the first to become prosperous". As Jim blossoms in his youth, he undergoes a lot of changes in his life especially the areas where his personal life is concerned. His experiences in the West are interwoven with his academic education which is what makes the story all the more interesting.Antonia to Jim is someone whom he respects and loves a lot. In fact, Jim’s memoir is titled ‘My Antonia’ and is dedicated to her, proving the depth of his admiration and love for her. His memoir is not just about the story of his childhood and his experiences but it focuses on Antonia and what she had meant to him. The beauty of this memoir lies in the ambiguity of love. Jim’s feelings and emotions towards Antonia are very stro ng and though he does admit his deep love for her, yet it does not explicitly advertise it. Jim takes pride in her strong physical appearance and her sexual appeal, but he is also very protective of her, from the other ‘creepy guys’ in the neighborhood. However, now and then he is filled with flashes of passion and this is evident when he tries to kiss her one night near the gate, while Antonia jokingly pushes him away. But, whatever his feelings were towards Antonia, it had a great impact on him for the rest of his life.... Jim takes pride in her strong physical appearance and her sexual appeal, but he is also very protective of her, from the other ‘creepy guys’ in the neighborhood. However, now and then he is filled with flashes of passion and this is evident when he tries to kiss her one night near the gate, while Antonia jokingly pushes him away. But, whatever his feelings were towards Antonia, it had a great impact on him for the rest of his life. The following lines testify Jim’s feelings for Antonia -"I'd have liked to have you for a sweetheart, or a wife, or my mother or my sister – anything that a woman can be to a man" (4.4.7).   Antonia’s influence over Jim helps to change his life. The impact is clearly evident when Jim states -"You influence my likes and dislikes, all my tastes, hundreds of times when I don't realize it. You really are a part of me" (4.4.7) Both Antonia and Jim have opposing characteristics. While Antonia is strong and decisive, Jim is mor e emotional, passive and indecisive. All the above points show that Antonia represents a part of his past which was simple, pure and innocent. Representing yet another part of his life which is his adolescence and adulthood is the character of Mr. Shimerda who was the father of Antonia, Marek, Ambrosch, and Yulka well. He was an intelligent and dignified gentleman who loved his life in Bohemia and hated his new life in America. Mr. Shimerda became heart broken because he could not adjust to the hard life on the farm. Jim took a great liking to Mr. Shimerda because he understood the sadness and exhaustion that he was experiencing by feeling alone in this world. Jim admired Mr. Shimerda and was

The Lone Ranger and Tonto Fistfight in Heaven Essay

The Lone Ranger and Tonto Fistfight in Heaven - Essay Example However Sherman Alexie doesn’t get satirical at all. He in his simple tones and simple style puts across the reader as what happened in the lives of his people. His metaphors although strong don’t overwhelm the reader. These metaphors come from his background, the culture he has been brought up in and the traditions and stories passed on from one generation to another. The thesis for analysis for this essay is the style of Sherman Alexie’s writing style which is literal and metaphorical, human and natural with a mix of reality and fantasy. The powerful use of metaphors and subtle hint towards magical realism gives a very special effect to the art of Sherman Alexie’s story telling. From the perspective of literature, they present many stories under one title. Some stories are kept in the background but their effects are seen on the characters and stories on the foreground, while some stories may go hand in hand in one story presented. Although the reader is reading many stories in one story, the main thread is not lost, which is what makes Sherman Alexie’s writing style unique and captivating. ... The party that is going on in the house is a vain attempt to fill the house with colours and laughter. In the same story Victor also states about the abject poverty during the festival time and his father being penniless to buy gifts for the family and the friends. The scene when Victor sees his father pulling out his wallet continuously, examining it as if there is miraculously going to be some money inside and keeping it back in the pocket touches every reader. It gives a very powerful picture in a very simple language. During other hurricanes broadcast on the news, Victor had seen crazy people tie themselves to trees on the beach. Those people wanted to feel the force of the hurricane first hand, wanted it to be like an amusement ride, but the thin ropes were broken and the people were broken. Sometimes the trees themselves were pulled from the ground and both the trees and the people tied to the trees were carried away. (Every Little Hurricane) Victor sees people hanging on, thin king that the hurricane will pass. He also talks about the people who were not party to the war, maybe by their own will or by situation, but they were affected alike by the war. He talks about people who tie themselves to trees to watch the hurricane, to feel it. Not all people participating in the action had a high end motive like sacrifice for the people and all, but they did participate in what was going on. Pulling out of trees indicates that whatever we stick to as a solid ground or possibly fundamental also gets shaken from the roots. The events and occurrences around you are so strong that they uproot you and change your direction altogether. One big hurricane in the story gives way to other little

Management Change Case Study Example | Topics and Well Written Essays - 3000 words

Management Change - Case Study Example In considering the movement of an organization from one country to another, the impact of the international environment has to be considered primarily as the organizational structure is highly influenced by the international marketing environment. In this discussion we focus on the nature of the organizational structure and the impact of the international environment on the company that is analysed here and would also discuss the cultural and non cultural factors that seem to affect an organization that shifts base from one country to another (Axinn and Matthissens, 2006). We examine the organizational structure, also the international environment and business environment on international marketing strategies. The implementation of the marketing mix is also considered along with the effects of internationalization and movements of a company from one country to another (Axinn and Matthissens, 2006; Balmer, 2006). ... The focus is on understanding the dynamics and relationship between the origin and destination markets. The four elements of marketing mix consist of the marketing tactics and deals with price, place, product and promotion. These four Ps are the basic elements of marketing but recent theories on 7Ps have added people, process and physical evidence in the marketing mix (Balmer 2006, Gronroos 1993). These elements are important as what customers and buyers get will depend on the combination of the suitability of the price, the quality or acceptability of the product in the market, promotional services done to sell the product and the place in which the product is being sold. Thus some major issues in marketing success relate to the place in which a product is launched or promoted and if the environment is suitable for the product then it would be considered as successful in terms of place, as the place is in accordance with the expectations of the company if the product sold and the ma rketing techniques used are commensurate with the needs of the environment or social conditions. As place defines the social environment, it is an important ingredient in the success of any marketing program and is a part of the marketing tool as the place will show the marketing environment to be considered as also issues such as how far the local environment is suitable for launch or marketing of the product (Gronroos, 1993; Balmer, 2006). The place involves the cultural as well as social values, the lifestyle of the people, the preferences of the surrounding locals and residents, and the geographical or environmental factors that can affect the sale of a product

Explorations of Tessellated forms for Architectural Application - Dissertation Example Trends in the Australian housing market are discussed, with connections drawn to emerging technologies as a means of expediting architecture and the mechanical process of construction. The principles of tessellation and 3-D printing will be discussed with proposed applications for architectural usage, as well as a discussion on the ramifications for the construction market. Table of Contents Introduction †¦p. 4 Literature Review †¦ p. 7 Conclusion †¦..p. 20 References †¦ p. 22 Introduction Architecture is among the principal forms of cultural expression available to any society, and represents a vital synthesis between technology, aesthetics, and the way in which a society perceives itself. Part of this perception is dependent upon the ability to adapt to modern technological realities and adapting to them accordingly. This investigation includes two new technological dimensions applied to theories of architecture to provide a new predictive element for the future growth of the design and construction principles inherent in architecture. The design principles upon which the urban landscape depends touch every aspect of modern life, from the aesthetics involved in fashion or jewelry, to the functional tools developed for mechanical or surgical work, similar design elements and technological solutions are applied which can inform urban design and architectural theories that shake our living societies. Design, architecture, and art in general form and intersect that will be informed by new advances described during the course of this analysis to create potential for a new dimension of design techniques applicable not only in architecture, but throughout a wide range of disciplines. This study will explore a possible future of architecture made available through the adaptation of two relatively novel scientific concepts: 3-D printing and tessellation. In a broad sense, the theories of tessellation will be explored at length, combined with the ne w potentials inherent in 3-D printing, which will be explored as a functional mechanism. The theoretical principles of tessellation are applicable to the technology of 3-D printing, and this investigation will explore possible developments of this design system for use in architecture. In terms of current trends in Australian architecture, it is necessary to remain cognizant of the aftereffects of the recent global financial crisis, however these international financial issues have affected Australia somewhat less than other countries. Regardless, it is inevitable that an interconnected global economy will still impact every advanced economy. Markets affecting new buildings and home design are nonetheless influenced by international issues, and as a result demand exists for structural flexibility as well as quality (Zenere, 2013). A trend towards increased flexibility underscores the need for a revision of old assumptions, and an adaptation of new technologies to meet the diversity of human needs with a greater range of options than in the past. Renewed interest in a flexibility of options will create a demand for novelty in terms of architectural design options, as old standards are revised to make way for the new economy. In addition to flexibility there is a demand for uniqueness within the reasonable boundaries of domestic comfort. Zenere (2013) describes a modern Australian home market where customers are interested in airy spaces with ample illumination and adaptability in terms of its overall design, in order to accommodate flexible living conditions. The modern economic circumstances prevailing throughout much of the industrialized world creates a social dynamic which

Ancient civilization Essay Example for Free

Ancient civilization Essay Ancient civilization was characterized with a culture that was rich in content, and embraced all aspects of human life. Religion for instance was so much emphasized as the basic support to human life. Assyrian winged protective deities were Egyptian religious figures. The chapel of Sekhem-ank-ptah is another unique aspect of history and has its weight on the wall hangings which had various writing inscribed on them. Lamassu, which is also known as lama is one of the Assyrian deities which had an obligation of protecting the people. This religious power existed between C883-613 in the Assyrian territory. The religious wall hangings found in the chapel of sekhen-ank-ptah has close similarity to Lama. All of them existed to in the ancient days with the wall hangings dating back to 2450 to 2350 BC. The region of existence of the wall hangings was however Sakkara in the late dynasty 5 (Tomasi, M. 2006). The two unique powers had varying representations. Lama was displayed as a large bull with horns and was always placed as a monument at the entrance of palaces. The gender of Lama was of the form of human males. Great artists always confirmed that the Assyrian deities with wings were actually apotropaic figures. Wall hangings on the other hands were made using thick papyrus which was obtained from swamps, lots of drawings were posted on the wall hangings and these drawings had various interpretations of divine nature. One similarity however is the material used to make them. All were made using sacred items. Lamassa represented a standing figure and served as a servant to a superior god. This meant that all visitors of the superior god were welcomed by the lame. Lama also had one great duty of protecting people against evil forces. The wall hangings on the other hands acted as a reminder of the baths to be taken in life. Some parts of the wall; hanging represented the process of giving offerings in church. The pictures had diagrams of animals in motion. Al these had interpretation. For example, the wall hanging on butchers at work and that showing plants in the field had an interpretation that the people were mainly farmers. Generosity in terms of giving food is also an output obtained form this diagram. The ancient Assyrian people believed in these symbols of deity and followed the beliefs carefully. Any violation of the precepts was believed to bring curses both then and the generation that followed

Problem Statement And Methodology Engineering Essay

Problem Statement And Methodology Engineering Essay Refrigeration or Cooling may be defined as the process of removing heat. This process may be accomplished by using one of the refrigeration systems; vapor compression, absorption or thermoelectric refrigeration systems. The first two systems need high and low pressure sides of a working fluid to complete the refrigeration cycle. The thermoelectric refrigeration system, however, uses electrons rather than refrigerant as a heat carrier. (Davis, 2005) Thermoelectric coolers are greatly needed, particularly for the developing countries situation where long life and low maintenance are needed. In this aspect, thermoelectrics cannot be challenged, in spite of the fact that their coefficient performance is not as high as for a vapor compression cycle. Thermoelectric refrigerators have the advantages of being small, lightweight, rugged, reliable, and insensitive to orientation, noiseless, portable and low cost in mass production. (Davis, 2005) Thermoelectric cooler has been widely used in military, aerospace, instrument, and industrial or commercial products, as a cooling device for specific purposes. This technology has existed for about 40 years. (Riffat, 2000) Many researchers are concerned about the physical properties of the thermoelectric material and the manufacturing technique of thermoelectric modules. In addition to the improvement of the thermoelectric material and module, the system analysis of a thermoelectric refrigerator is equally important in designing a high-performance thermoelectric refrigerator. (Huang, 2000) The heat flux generated in the processor chip is rising day by day at a very fast rate with development because of reduction in CPU sizes and large amount of heat load generated at the chip. Consequently, it is becoming a challenging task for researchers to handle such enormous amounts of heat fluxes. Moores had proved that number of transistors on a integrated circuit is increasing exponentially year after year .So heat load in the CPU also increases at the same rate with the increase in the speed moreover the size of the chip today which we normally talk about is of the order of mm which is in turn making problem more complicated. The high heat generation inside the CPU may result in slowing down the computation speed, failure of the processor chip, gate oxide breakdown, effect on screen resolution and many more electrical failures as well as mechanical failures (Davis, 2005) Presently in CPU very complicated designs of air cooled heat sinks are used which dissipates heat to the surroundings by flowing large volumes of air. These heat sinks have two major shortcomings. Due to space constrains air should be thrown at very high velocities and to maintain such velocities big size fan has to be used. Also, the air flowing at high velocities creates a lot of noise. Moreover, in air cooled units there is no active cooling device so we cant go below the ambient temperature. As a result working at high speeds in the hot ambient conditions had become extremely difficult. Chip cooling is one of the bottlenecks in the high density electronics. There is need of some better cooling techniques for the same. So, now a day researchers are working a lot on liquid cooled systems, because they have nearly 10 times (Davis, 2005) the heat transfer coefficient than that of air cooled ones. In water based liquid cooling systems, the heat is pumped to water block by some cooling device from which water takes away the heat to finally throw it in the surroundings . The most commonly used device to pump heat to water block in such system is TEC (Thermoelectric coolers). TEC consumes their own power and cool down the chip by extracting the heat from it and transferring it to the water block. Water runs inside the channel in the water block and takes away the heat from it. The hot water is further cooled in the condenser. With the help of Thermoelectric water cooling system the chip temperature can be easily made to go below ambient temperature which is not possible by the existing systems, and thus the CPU can be made to operate at high speeds and higher loads in even hot ambient conditions. Thus TEC have potential opportunities for chip cooling and can prove very effective if a proper system is developed for the same. 1.2 Problem statement Chip cooling is one of the bottlenecks in high density electronics. An enormous amount of heat flux is generated by the modern processor chip. Nowadays many complicated designs of air cooled heat sinks are used, but off late the heat fluxes have attained such a level that to handle them very large volume flow rate of air is required. So due to space constraint, in order to achieve large flow rates, air should be blown at very high velocities which in turn result in increased levels of noise. Another major disadvantage of air cooling is that we cant go below ambient temperature and as a consequence, tendency of chip failure in the computers working in ambient condition of about 35 °C 45 °C increases a lot. For all these reasons it has become apparent that the heat fluxes have reached such a level that air cooling cant handle them efficiently. Thus the present scenario necessitates the use of active cooling devices. Thermoelectric coolers having the ability to cool below ambient and having advantage of being compact, light weight, free of moving parts and precise temperature control have high potentials for chip cooling. It is known that the temperature of the thermoelectric module is the main criterion for its reliability and performance. The temperature rise of the hot side above ambient is dependent on the thermal resistance of the path that the heat sink. Reducing the thermal resistance of the heat sink contributes to the reduction of the thermal resistance of the path and hence an increase in the performance. So a liquid heat exchanger with spiral flow passage having dimples is used. Dimples result in effective heat transfer by creating turbulence and thus enhancing the performance of the system. 1.3 Research Objectives Understanding the basics of Thermoelectric coolers, working of Thermoelectric Cooling Systems and parameters that governs the performance of such systems Design, fabrication and development of an efficient thermoelectric cooling system for computer chips Carrying out experimentation and analysis of the performance of the developed system 1.4 Methodology 1.5 Work Plan These are some of the important tasks that would be performed during this research Understanding the basic concepts of thermoelectric cooling Study of the existing CPU cooling techniques Literature review regarding the topic and study about the effect due dimples along the flow of water Deciding the various parameters for which system has to be designed Deciding about the thermoelectric module which will produce the desired cooling effect Design of the experimental set up and identification of the various equipments to be required Market survey for all the required equipments Procurement of the equipments Design and fabrication of the dimpled water block Design and fabrication of the heat exchanger Preparation of the experimental set up Carrying out experiments and obtaining the results Analysis of results Checking out the performance of the thermoelectric module used Comparison of the designed water block with some commercially existing water block Discussions and conclusion Report writing 1.6 Expected Outcomes An understanding of the application of thermoelectric cooling systems would be developed. Important advantages of the thermoelectric cooling systems in current scenario of high density electronics would be presented. The complete thermoelectric cooling unit for CPU chip would be designed, fabricated and tested for the desired loads Chapter 2: LITERATURE REVIEW 2.1 The History of Thermoelectrics In 1821, Thomas Seebeck discovered that a continuously flowing current is created when two wires of different materials are joined together and heated at one end. This idea is known as the Seebeck Effect (Figure 1.1). The Seebeck effect has two main applications including temperature measurement and power generation. (Global Techno Scan, nd) Figure 1.1 Seebeck Effect S= dV / dT; S is the Seebeck Coefficient with units of Volts/K S is positive when the direction of electric current is same as the direction of thermal current In 1834, a French watchmaker and part time physicist, Jean Peltier found that an electrical current would produce a temperature gradient at the junction of two dissimilar metals. This effect is known as the Peltier Effect. This idea forms the basis for the thermoelectric refrigerator (Global Techno Scan, nd) Figure 1.2 Negative Peltier effect a) For à Ã… ¸ When current is allowed to pass through n-type semiconductor shown in above circuit, high energy electrons move from right to left resulting in cooling of far end. Thermal current and electric current flow in opposite directions (Global Techno Scan, nd) Figure 1.3 Positive Peltier effect b) For à Ã… ¸ >0; Positive Peltier coefficient When current is allowed to pass through p-type semiconductor shown in above circuit, high energy holes move from left to right resulting in heating of far end. Thermal current and electric current flow in same direction (Global Techno Scan, nd) q=à Ã… ¸*j, where q is thermal current density (Heat flux) and j is electrical current density. Also, à Ã… ¸= S*T (Volts) Peltier coefficient Where, T is the Absolute Temperature Scottish scientist William Thomson (later Lord Kelvin) discovered in 1854 that if a temperature difference exists between any two points of a current carrying conductor, heat is either evolved or absorbed depending upon the material. If such a circuit absorbs heat, then heat may be evolved if the direction of the current or of the temperature gradient is reversed. 2.2 Thermoelectric Refrigeration A thermoelectric device is one that operates on a circuit that incorporates both thermal and electrical effects to convert heat energy into electrical energy or electrical energy to a temperature gradient. Thermoelectric elements perform the same cooling function as Freon -based vapor compression or absorption refrigerators. Energy is taken from a region thereby reducing its temperature. The energy is than rejected to a heat sink region with a higher temperature. Thermoelectric elements are in a totally solid state, while vapor cycle devices have moving mechanical parts that require a working fluid (Tellurex, nd) Thermoelectric modules are small, sturdy, quiet heat pumps operated by a DC power source. They usually last about 200,000 hours in heating mode or about 20 years if left on cooling mode. When power is supplied, the surface where heat energy is absorbed becomes cold; the opposite surface where heat energy is released becomes hot. If the polarity of current flow through the module is reversed, the cold side will become the hot side and vice-versa. Thermoelectric modules can also be used as thermocouples for temperature measurement or as generators to supply power to spacecrafts and electrical equipment. (Tellurex, nd) Thermoelectric devices can also be used as refrigerators on the bases of the Peltier effect. To create a thermoelectric refrigerator, heat is absorbed from a refrigerated space and than rejected to a warmer environment. The difference between these two quantities is the net electrical work that needs to be supplied. These refrigerators are not overly popular because they have a low coefficient of performance. The coefficient of performance for thermoelectric refrigerators can be calculated by dividing the cooling effect by the work input. (Tellurex, nd) 2.3 Semiconductors The semiconductor materials are N and P type, and are so named because either they have more electrons than necessary to complete a perfect molecular lattice structure (N-type) or not enough electrons to complete a lattice structure (P-type). The extra electrons in the N-type material and the holes left in the P-type material are called carriers and they are the agents that move the heat energy from the cold to the hot junction. Heat absorbed at the cold junction is pumped to the hot junction at a rate proportional to carrier current passing through the circuit and the number of couples. Good thermoelectric semiconductor materials such as bismuth telluride greatly impede conventional heat conduction from hot to cold areas, yet provide an easy flow for the carriers. In addition, these materials have carriers with a capacity for transferring more heat. Since semiconductors were found to have large Seebeck coefficients, good electrical conductivities, and poor thermal conductivities, on e has made a breakthrough in the use of the Peltier-effect in thermoelectric devices to produce refrigeration. Currently, thermoelectric refrigerators, made of semiconductor, materials, have many interesting applications because of their small size, simplicity, quietness and reliability. 2.4 Basic Working Principle of Thermoelectric Coolers Thermoelectric coolers are semiconductor devices which works on the principle of Peltier effect (Haung, 2005) i.e. when a current is passed between the junctions of two dissimilar materials then a temperature difference is created between the two junctions. In thermoelectric coolers we have a P type and an N type semiconductor connected together when we pass the current, at the cold junction electrons travel from P side to N side as P type being at lower energy level and N type at higher energy level. So when electron travels it absorbs energy at the cold side. Similarly at the hot side electron travels from N side to P side thereby releasing the energy. And in this way a temperature gradient is established between hot side and cold side (Haung, 2005) 2.5 Advantages of Thermoelectric Coolers Thermoelectric coolers have some unique advantages over other cooling systems. The various advantages are (Chien, 2004) Ideal for localized cooling due to small size Highly controllable cooling power Convenient power supply Precise temperature control Sub-ambient cooling capacity Spot cooling Compact, Quite, and free of moving parts Low maintenance 2.6 A typical thermoelectric cooling system: Fig. 1 shows working of a thermoelectric system. The heating and cooling functions of the thermoelectric system can be interchanged by reversing the polarity of the direct current applied to it. Capacity control in a thermoelectric system can be achieved by varying the voltage applied to the couples either by a variable voltage control or by switching series and parallel circuits. As the voltage drops, the temperature difference between the hot and cold side is reduced. (Chien, 2004) On the cold side of the module we have the heat source from which heat is to be removed and on the hot side we have a heat sink which finally throws the heat into the ambient. Design of the heat sink is an important parameter for improving the performance of the thermoelectric module. For many applications, the advantages of TEC outweigh its main disadvantage of low coefficient of performance. (Chien, 2004) Figure 2.1 Thermoelectric cooler (Chien, 2004) 2.7 Thermal Parameters Governing Performance of TEC The selection of a thermoelectric for a particular application is mainly dependent on the three important parameters. These are temperature of the hot surface (Th), the temperature of the cold surface (Tc) and the amount of heat to be extracted at the cold side of the module (Qc) (Haung, 2005). The heat sink is attached at the hot side of the module where the heat gets released when the DC power is applied to the module. The hot side temperature of the module while using a air cooled heat sink whether natural or forced convection, can be found out using below equations (Haung, 2005) Th = Tamb + Rth(Qh) (1.1) Qh = Qc + Qp (1.2) The temperatures rise above ambient, of the hot side, takes place because of the thermal resistance of the heat. If we know the thermal resistance of the heat sink then the general estimates of the rise in temperature above ambient are as stated below: (Haung, 2005) 20 °C to 40 °C in case of Natural Convection 10 °C to 15 °C in case of Forced Convection 2 °C to 5 °C in case of Liquid Cooling (In this case is the rise above the liquid coolant temperature) The performance coefficient for a thermoelectric cooling system can be calculated with the help of the following equation: 2.8 Application of thermoelectric cooling TEC (Thermoelectric Cooler) is different from conventional compression refrigeration; there are no moving parts. Since there are no moving parts, there is nothing to wear out and nothing is generating noise. There is no refrigerant to contain so the problem of handling a two-phase change over is simplified. Pressure tight tubing is replaced by electrical wiring. There is no ozone layer hazard (Melcor, nd). Thermoelectric coolers offer the potential to enhance the cooling of electronic module packages to reduce chip operating temperatures or to allow higher module powers. Thermoelectric coolers also offer the advantages of being compact, reliable, and their degree of cooling may be controlled by the current supplied. Unfortunately, compared to vapor-compression refrigeration, they are limited in the heat flux that they can accommodate and exhibit a lower coefficient of performance (COP). These two limitations have generally limited thermoelectrics to niche. The thermoelectric coolers are used in the electronics of the cruise missile, critical equipment on aircraft, critical camera components in a pod aircraft navigation system and many military applications. Thermoelectric coolers provide compact heat exchangers that are not attitude-sensitive and do not contain excessive tubing and fittings that can be susceptible to vibration 2.9 Previous Work done at International level Till today air coolers are meeting the needs of CPU cooling, with the increased size of heat sinks and an increase in fan speed. The typical resistance of air coolers with high fan speeds is 0.2 °C/W (Bar Cohen, 2000). But with further increase in the heat flux, air cooling techniques seems to be diminishing because of the limitations already mentioned. The next best solution to the problem is the use of liquid cooling techniques as the liquids have relatively very high convective heat transfer coefficients then air and thus minimizing the thermal resistance. The liquid cooling systems involves water block for efficient heat transfer to the liquid. Experiments have been carried out by mounting water blocks directly over the CPU chip and they have shown to be very efficient then the air cooled techniques. With the use of direct water-cooling techniques the chip temperature can be kept at 30 °C for an ambient condition of 25 °C with a CPU load of 60W whereas with air cooling it goes to 45 °C (Bar Cohen, 2000). But with the development of thermoelectric coolers it had made possible to take the chip temperature even below ambient. Thermoelectric Coolers have unique advantages over other cooling devices Chein and Huang (2004) studied usage of thermoelectric cooler for electronic cooling. The cooling capacity, junction temperature, coefficient of performance (COP) of TEC and the required heat sink resistance at the hot side were computed. They found that the cooling capacity could be increased as Tc is increased and ΆT is reduced. The maximum cooling capacity and chip junction temperature obtained were 207 W and 88 °C, respectively. The required heat sink resistance on TEC hot side was found to be .054 °C/W. A micro channel heat sink ( with size of 55mm x 55mm with channel width of 0.3 mm) using water or air as coolant was also demonstrated to meet the low thermal heat sink resistance requirement for TEC operated at maximum cooling capacity conditions. Huang et al in 2005 studied the distribution of temperature for a thermoelectric cooler under the effects of Joule heating, Fourier Heat conduction, Thomson effect and convection and radiation heat transfer. They tried to enalyze and explore some of the important things like Thomson effects influence on the distribution of temperature, on the amount of heat that flows back to the cold side, the maximum temperature difference attained and the maximum amount of heat extracted etc. They finally concluded that other than improving the thermoelectric materials for increasing the cooling efficiency of the module the other possible way is to take the advantage of Thomson effect this also helps in improving the cooling efficiency. Researches are already going on for incorporating thermoelectric water cooling systems for the CPU. The key factor in using such kind of systems is to have highly efficient water blocks with low thermal resistances and to have thermoelectric modules with proper Qmax. Many complicated water block design exist in the present market. The typical thermal resistances of the water blocks used presently for such systems are 0.08 °C/W (Bar Cohen, 2000).

Fight Club Essay -- Film Movie

This movie is mainly about a narrators search for meaning and the fight to find freedom from a meaningless way of life. It setting is in suburbia, an abandoned house located in a major large city. Ed Norton, plays the nameless narrator, Brad Pitt, is Tyler Dunden, and Helena Boaham Carter is Marla Singer, the three main characters. David Fincher directs this film in 1999, which adapted it from the novel written by Chuck Palahnuik. It begins depicting Edward Norton, the narrator, working for an insurance company as a representative, who produces evidence for recalling automobiles. He lives in a 15 story, glass front condominium, with the best expensive furniture, designer clothes and a totally empty way of life. Society has yet to understand how employment can influence a person life experiences. His first experience in solving his problem is to seek medical advice for insomnia, which is not the answer. He was advised by his doctor to really see pain, participate in is a group of men who have testicular cancer and really experience pain. This begins his phony search and fix to his search for a painless life. He portrays his self as a cancer survivor, and creates an identity to fill his emptiness, and thus ends up attending seven groups a week. He then meets Bob, who is later killed because of his participation in a bombing of a coffee house. During this process the narrator meets the chain smoking, Marla Singer. Confronted with realization, they were both liars and looking in the mirror irritated him, Marla and the narrator agreed to a plan not to be at the same group, and they could both also avoid self-reflection and contact at the same time. These groups lead the narrator into finding his ?cave and finding t... ... up, Marla and the narrator holding hands and he says ?you met me at a very strange time in my life.? The last song is ?Where is my Mind It also can be a symbol representing the narrators search for his true identity. This movie is sending a message to society about what can happen in a world of confused, angry men. Its points to the hypocrisy of the general public which promotes enforcements of movie ratings, gun control but drops its children off the see ?The Matrix?. In my opinion, this is a good movie for college students, who are studying in Sociology, Mental Health or Nursing Careers. This assignment required many skills, to understand the information you required. This information was hidden in the plot so distinctly a freshman student could have easily missed it. I think this movie would be a challenge for upper level college students.

Distance Learning Essay -- Essays Papers

Distance Learning In recent years, there has been a trend in the way that many major institutions of higher learning have been teaching their students. This change of pace in the education world is what is known as distance learning. Distance learning is the form of schooling that can be done over the Internet, and never actually being forced to be present in a classroom or even on the campus. According to Joel Snell, correspondence courses were the predecessors to what we now know as distance learning (258). Many people say that distance education is the future of our nations’ education, however there are many arguments against the wide spread establishment of distance learning programs. Although distance learning may seem like a bright future for education, nevertheless, it will never be as successful as campus learning, because every student must be self-driven and also highly motivated, the lack of access to libraries and other sources of information, and also face-to-face inter action is necessary for a good education. Many people think that distance learning is a perfect fit for men and women working on their master’s while still maintaining a job. When a person enters the real world and gets a job, they will not always have a lot of time on their hands that would allow them to go to classes. The ability to take their classes at anytime possible is one of the most appealing factors for distance learners (Flanagan). Another reason as to why distance learning is a perfect match for men and women taking classes while working is the motivation factor. Both Snell and Mariani agree that in order for a person to succeed in distance education, they must be highly motivated, which does not describe the ... ...he newest equipment today will just give you out-dated equipment a few months after the initial implementation (Porter 41-42). Based entirely upon the facts that are presented in so many academic sources, distance education programs are hard to implement as well as to maintain, so that it why that many fail, and they are not widely accepted in today’s day.

Consumer Securities Trading in United States

The following is an in depth look at the effects the Internet has had on trading securities in the United States. Its purpose is to define the impact of the Internet by determining specific changes in the structure of the trading market as a result of the numerous online brokerages that have surfaced in the past few years. A brief look at traditional brokerages and market characteristics prior to the advent of the Internet provides a foundation with which to measure many of its impacts. The arrival of the online brokerage model has not only introduced an entirely new vehicle with which to trade securities, but it also beginning to effect the way traditional brokerages view their own business models. Specifically, it appears that both the online/discount model and full service model of brokerages will both succeed in the next few years, with the top firms exhibiting characteristics somewhere between the two extremes. New Ameritrade television commercials debuted early this year with a twenty-something-year-old punk extolling the virtues of his new brokerage account to various business men and women. Perhaps the witty E*trade commercial featuring monkeys that first aired during the 2000 Super Bowl was more notable. These commercials are quite a contrast to the traditional brokerage commercials of Merrill Lynch, Morgan Stanley Dean Witter, and Fidelity among others. This contrast is for good reason. Online brokerages have uprooted the traditional model of consumer securities trading and have attracted a critical mass of followers. Before brokerage fees were deregulated 1975, eliminating fixed commissions, trading was something only done by the wealthy. Since then, fees have dropped considerably among the full-service firms making it possible for more and more people to manage portfolios. Until 1995 there was still a fundamental restraint for many consumers: access to timely and accurate information at any time from their own computer. With the arrival of online brokerages in 1995 came a slew of options for investors, new and old, to access an abundance of information and research, and to initiate their own trades all at considerably discounted fees. According to Deutsche Banc, as of 2Q00, online brokerage accounts represented approximately 25% of all accounts in the United States. Furthermore, by 2003, online brokerage accounts are estimated to control 50% of the brokerage market. The online model has already attracted nearly 20 million investors, initiating an increase in overall trading volume. An brief examination of the brokerage industry pre-arrival of the Internet and an in depth look at the brokerage industry now illuminates the many differences and possible implications for the future of consumer securities trading in the United States. Traditional brokerages have been operating freely since 1975. The deregulation of brokerage fees at this time allowed new firms to enter the market, marking the first major alteration in the way Wall Street traditionally offered its services. Before 1975, the market consisted solely of â€Å"full service† firms, those firms who offer trading, research, and financial advice through brokers or financial advisors at a considerable fee. After fees were deregulated, â€Å"discount† firms began to appear, offering consumers smaller fees, but at the cost of less research and financial advice. The market slowly split between these two types of business models, but they were fundamentally similar for 20 years: generate revenue by providing consumers the ability to trade and receive financial advice based upon firm research. The concept of having a broker, or financial advisor who acts as an agent for consumers, was the prevailing idea of stock trading in between 1975 and 1995. Many of those who had portfolios would leave its management entirely up to their brokers, others would call periodically for advice, and some would be actively co-managing their portfolios with the broker. The prevailing model for securities trading was still professionally managed, although different levels of management and cost evolved at this time. Wall Street was altered again in 1995, probably more significantly than in 1975, when securities trading and the Internet converged. According to the Securities Industry Association, K. Aufhasuer & Company was the first to execute securities trading online in 1994. However, it was not until 1995 that the first online brokerages debuted their new business model. Momentum mounted quickly, as many investors flocked to the lure of extremely discounted prices and quick trade execution. Without the â€Å"brick and mortar† presence typical of the traditional brokerages and a significantly less extensive network of research and financial advice, online brokerages can offer transactions at fractions of the costs of traditional brokerages, even of the traditional discounters. The first online investors were, and still are, predominantly â€Å"a mix of young, first-time investors and older, more experience ones,† according to a McKinsey & Company study. When online brokerages first surfaced, they introduced an entirely unique channel for delivering securities trading to consumers. No other brokerage firms offered the ability to trade securities over the Internet; it was exclusively reserved for those companies referred to as â€Å"online brokerages. † This has changed however over the past couple of years. Traditional full-service brokerages are beginning to adopt their own online components. The two most frequently cited reasons for the scramble of full service firms to enter the online market were customer pressure, and the fear of asset flight to online brokerages, according to a Deloitte & Touche Survey. The ability to distinguish these early online brokerages from full service firms is no longer a matter of whether or not they offer online services. The distinguishing feature now is between the cost of their services, segregating firms into a classification again of â€Å"discount† or â€Å"full service. In a sense, the online model has redefined â€Å"discount,† moving the discount brokerage to a much further extreme. Indeed, it is true that most of the firms that are classified today simply as â€Å"discount† are founded on an online business model or have quickly adopted online capabilities, but many of the full service firms, as mentioned, are turning to the online channel in hopes of competing with the discounters. Therefore, when an â€Å"online brokerage† is referred to, it implies both the discount firms and the few full service firms with online capabilities. The evolution of the online brokerage market has been explosive in growth, catapulting from just one online brokerage in 1995 to an estimated 170 in 2000, totaling 19. 5 million online accounts (refer to Figure 1 below). The first online brokerages to emerge were predominantly â€Å"deep† discount, followed by mid discount firms, and finally some of the traditional discount incumbents adopted an online strategy and are now classified as mid-tier firms. To illustrate this trend, consider the emergence of 5 of today's top 6 online brokerages: In 1996, two major deep discount firms emerged, Datek and Ameritrade. Over the next two years, two major mid-discount firms appeared, E*trade and DLJdirect. In 1998, Charles Schwab made their presence felt in the online market which was one of the few traditional discount firms before the online model developed. Fidelity quickly followed suit. This upsurge of online brokerages and the trend for some of the traditional brokerages to go online has had some lasting effects on the securities trading market, which will be explored in the next two sections. The impact of online brokerages is manifested in nearly every aspect of the securities trading market today. Trading volume increase is one of the largest impacts, as a result of the ease and availability of trading that online accounts bring to consumers. It is worth examining the numbers to determine if the large increases in trading volume are actually a result of online accounts, or merely pure correlation with a booming bull market. Over the past decade, the volume of shares traded on the NASDAQ stock market has grown at a compound annual rate of 26%, but since the arrival of online brokerages in 1995, it has grown at a rate of 30%. Although this is not an enormous increase, it is certainly quite significant. To look at it in another light, online accounts represented 15% of all brokerage accounts in the US, but more than 37% of the trading volume. Based upon past experience in the stock market, it may seem that this increase in trading volume is an entirely productive result. However, much of the trading volume from online accounts is a result of day trading, which raises concerns with the SEC. Day trading was not possible before online brokerages made it possible to quickly and effectively trade securities multiple times daily. It is a speculative business, more so than the traditional brokerage business. As Deloitte & Touche describes it, â€Å"Customers usually [trade] in and out of several securities positions every day hoping to earn a positive spread on their transactions. † The SEC is responsible for maintaining fair and orderly markets, to protect investors, and to enforce securities laws that were established upon principles that day trading discards. According to a Deloitte & Touche survey, 62% of discount firms said they would offer services to day traders versus 0% at full service firms. Most online brokerages recognize that day traders make up an integral portion of their customer base, and do not wish to sacrifice the relationship. Day trading is one negative result of the advent of online brokerages that will remain a challenge for some time to come. Another notable consequence of online brokerages is the further development of after hours trading. The New York Stock Exchange first expanded its hours to â€Å"off hours† trading in 1991. The NYSE added a modest extension extending the after hours from 4pm to 5:15pm. It is now possible, with an online account to trade at any time. This can be advantageous to many investors in giving them more flexibility regarding time availability and for investors overseas who have holdings in US securities and cannot trade at regularly scheduled hours. After hours trading in 1999 represented 50% of all online transactions. Online brokerages have improved execution time quite dramatically to an average of 20 seconds per trade versus nearly 60 seconds for full service firms. In addition to improved execution time, the reliability and accuracy of online executions at discount firms is generally considered to be far superior to full service firms' online counterparts. The reasons most frequently cited for this are two-fold. First, most discount firms are built upon an online model, it is their core competency, allowing them to devote all of their efforts to perfect the core of their business model. Discount firms rely on trade volume for revenue, not asset accumulation, so it is imperative that their trade execution is the best that it can be. The second reason for superior trade execution at discount firms is that full service firms simply do not devote the same technological resources to their online channel. Full service firms focus primarily on performing cutting edge research, and providing sound financial advice through its network of brokers. The speed and reliability in execution at discount firms has been one of the top attractions of investors, along with largely discounted prices. The online brokerage market has also greatly impacted the availability of brokerage services to those who were previously unreachable. This hinges upon Internet penetration in the US, which is approaching 120 million active adult Internet users, or a penetration rate of 50%. As was mentioned previously, the first investors to move online were mainly those who were brand new to securities trading, or those who were experienced enough to feel confident trading with little or no professional advice. Most of them brought below average asset values online. In fact, in mid-1999, although online accounts represented 15% of all brokerage accounts, they only represented 5% of the total assets. As stated previously, these accounts also accounted 37% of the trading volume. That would indicate that the online brokerages do not focus on producing revenue through asset accumulation, but through trading volume. This has some major implications to be discussed in the next session. The majority of discount firms rely on trading volume to create revenue through their online offerings. This means they depend on accumulating customers who trade frequently in order to collect fees for trades made. Trade volume has been increasing quite dramatically over the past few, as the percentage of online trades increases as a proportion of total. This bodes well for the online brokerages who are accumulating customers, although those players who are at the bottom of the pack will likely fall out soon. The market is remarkably consolidated after just 4 years in existence. In fact, the top ten online brokerages comprise 90% of the online assets and accounts, and the top 4 comprise 86%. Those brokerages who are having a tough time accumulating customers and trade volume even while the online brokerage market is hot, will likely fall out soon. Referring back to Figure 1, it can be seen that the number of online brokerage firms is expected to decrease over the next few years while the number of online accounts increases. The online industry is consolidating quickly while continuing to grow. Although there is still a large disparity between discount firms and full service firms in terms of how they operate and what they offer, this is likely to change in the coming years. Already, the trend for full service firms to go online is in motion, and there are even some discount firms that are beginning to complement their trading services with plans for banking, insurance, and bill payment services. Currently, discount firms have approximately 74% of their transactions online versus 18% online at full service firms. In a Deloitte & Touche survey, 100% of full service firms said they planned to use online trading to enter new businesses, create alliances, or shift the business model, and 74% of discount firms said they planned to add additional services that are typically offered only by full service firms. It appears that the two extremes in brokerage services are headed towards a common middle ground. As the author of the Deloitte & Touche study put it, â€Å"the distinction between discount brokers and full service firms is becoming less evident. There is distinct evidence that the brokerages that will prevail in the next decade will have features of both a discount brokerage and a full service brokerage. A 50/50 hybrid model of online and full service could prevail, but it is more likely that the future constituents will be based on one core competency (online vs. full service) and have significant characteristics of its counterpart. This is because each business model appeals to different segments of the population. It is generally agreed that full service firms have a distinct advantage in advertising dollars and brand equity, and appeal to investors with more money and/or less knowledge of investing. Online brokerages appeal generally to investors with less money and/or more knowledge of investing. At this point in time, they are quite distinct, but the gap is closing. Another salient example of this phenomenon is that the top focus of current marketing strategies for 18% of online brokerages is to build brand equity, a la the full service firms. Each model, discount and full service, is moving to a common ground. The question that now stands is, who will win out? It is not an easy task to predict the future, or the future of brokerage services in the United States for that matter. One thing is for sure: the online channel will succeed. The top brokerages of the future will certainly incorporate online components very significantly. Those that will continue to succeed will be able to be flexible and adjust to the changing demands of consumers and technology, just as the top firms today are able to embrace the online channel. As Deloitte & Touche put it, â€Å"firms that cannot be innovative will find themselves niche players or acquisition targets. â€Å"
