Teacher Interview Essay Example for Free

Teacher Interview Essay For this project I decided to interview my high school football coach from Brewster Washington Ed Ashworth, who teaches English. I asked a verity of questions to help get an understanding of what it take to become a teacher and to just get a better idea of it all. The first question I asked was, How much time outside of school do you spend on your job? â€Å"Well between grading papers and making lesson plans for class and other materials, probably about 16-20 hours a week. About and hour before school and a couple hours here and there after school, plus weekends. † he said. Next question I asked was, How do you come up with the lesson plans? â€Å"Its not easy to come up with lesson plans all the time, I try to make the assignments interesting so the students dont get bored of the same thing. I there is something that is fascinating outside of class that I think I can incorporate into class I try to do that, weather its something on the news or something going on with the school so the students can speak their mind, thats usually makes it more fun for them. † said Mr.Ashworth. Next I asked, What do you do with a failing student? And a student with behavior problems? â€Å"I try to make sure I am send grade checks home to there parents, I also ask the students if they need extra help of if the need to stay after class for some one on one learning. And for the behavior problem kids I usually send the student outside and have a discussion and let the student they need to get their act together. † he said . Then I asked, What are additional duties besides teaching in the classroom? â€Å"Teachers meetings, parent meetings, Homework grading and tests, Also advising the students they are assigned to make sure they are on track for graduation. † says Ashworth. Next I asked, Whats the most rewarding part about teaching? â€Å"The most rewarding part would have to be when you see a student turn things around, going from not trying in school to doing good in the class because they realize that school is important for there future. † he said. The last question I asked was, What made you choose to be a teacher? â€Å"I had a couple teachers that really made an impacted in my life and I ever since then I know I wanted to be a teacher to help kids and to make an impact in their lives. † I learned a lot from the interview with Mr. Ashworth, hearing what he had to say about teach just making me wanna be a teacher even more than before. The very last quote he said is the one thats going to stick with me, because I had a couple of teachers that made an impact in my life as well and its a big part of why I want to become a teacher to help kids and to maybe change their lives.

Elie Wiesel :: essays research papers

Near the end of Elie Wiesel’s time in the concentration camps, Wiesel began to question many things. He had questioned G-d, not because he believed in him so much, but because he almost had no belief left. He also questioned himself when thoughts of leaving his father came to mind. Had Wiesel left his father, life would surely have been easier for him to survive. But throughout all these immoral thoughts going through his head, he â€Å"had done well to forget† them. (87)   Ã‚  Ã‚  Ã‚  Ã‚  His time in the Holocaust left him questioning G-d many times. Wiesel went from a religious young man to a near atheist adult by the end of his torturous time at the camps. Wiesel felt that G-d was powerless and silent during the Holocaust. G-d wasn’t going to save anyone this time. The only people who were going to get out of this alive were the ones who were physically and mentally strong enough. Wiesel was lucky enough to be one of the very few who made it out to tell his story. However, he still watched as his mother and sister were taken away to the crematory and his father died in his bed.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Wiesel’s weakest point mentally was when he heard that Rabbi Eliahoo’s son abandoned him during the death march from Buna. He also heard that a nameless child beat his father to death for a small portion of bread. It was there an then that he gave minor consideration to getting rid of his father. It is the brutality of the entire Holocaust that led Rabbi Eliahoo’s son and the unnamed child to do such things to their fathers. A father/son bond is one of the strongest bonds known to man. But, for both children, their own survival came first. Eventually, Wiesel was forced to make the same kind of decision. He had taken some of his father’s food during the last couple of nights he was living because he knew that he would most likely die anyway. He gave up hope on his father just like the others.

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

Review Of The Defense Of Globalisation - 1216 Words

BOOK REVIEW : â€Å"IN DEFENSE OF GLOBALISATION† INTRODUCTION: The subject of globalization can trigger a wide range of responses when brought up in a discussion. To its supporters, globalization represents advancement, monetary development, and promotes a better future. To its critics, it connotes greed, exploitation, and corruption. These assorted qualities of perspectives is maybe due to the way that globalization is naturally intricate and includes distinctive financial and social subtleties at different national and worldwide levels. Understanding globalization, in this manner, obliges one to perceive how these variables interrelate and impact each other. One text that makes a successful job of investigating these complex connections is Jagdish Bhagwati s â€Å"In Defense of Globalization.† Bhagwati, a Columbia University economics professor and author of numerous books on trade, makes all the right economic arguments, however without the flurry of factual connections frequently used to put forth the defense. Rather, he recounts the narrative of how globalization has conveyed a superior way of life in less developed nations, and how experiments with different avenues regarding protectionist import substitution policies have deliberately failed. However unlike numerous other texts on this subject, Bhagwati s presentation does not address the issue from a principally emotional point of view.
