Abstract The experiment involved constructing a microphone from the materials given to us. Our group was supposed to make as sensitive microphone as possible. This laboratory was also intended to introduce the concept of sensor materials which can be made to act as electric sense organs. Our group has lost the competition, but even so by the end of the lab we understood how the microphone works and was able to construct it and test it using the Lab VIEW program. Introduction A real microphone consists of a diaphragm that is connected to a magnet. Sound waves vibrate the diaphragm and move the magnet in and out. The magnet is inside a coil of wire. When the magnet moves inside a coil of wire ...

Airline Terrorism Whether we would like to admit it or not, aircraft terrorism is a very real and deadly subject. Inside nothing more than a small suitcase, a carefully assembled explosive can bring an ending to the lives of countless men, women, and children, with no preference or regard to age, sex, and religion. In a single moment and flash, families are torn apart as their loved ones become victims of terrorism. As the airline price wars have continued to rage, the amount of fliers increase at phenomenal rates. The airports are filled to maximum capacity with people all interested in just surviving the long lines and finally finding relaxation in their aircraft seats with the help of a c ...

... industry. Consumers are now demanding lower prices and more luxuries in their cars. To deal with this consumer demand, auto manufacturers have begun by lowering employee pay rolls, replacing employees with machines and more capable workers to improve productivity, and many times merge with other companies to better compete in the market. Production growth has been about 2-3 percent for the past few years in the auto industry, and hopefully will continue by implementing new cost efficient procedures. American industries, competing in the international markets, face the problem of a strong dollar compared to the weaker currencies of foreign nations. This means that American cars to foreign ...

Biased Judgement Our society interpret a person's outer appearance as a reflection of their inner- self. This is likely due to Heuristics. In the case of representativeness heuristic, a judgement regarding the person would be determined by the by the outward clues that the person reflected of themselves. One outward clue is the appearance of a person. If a person is neat in appearance and dressed in something like gothic-garb (black clothes and makeup). A person dressed in such a way could be judged as dark and extreme. This would be a fair assumption given that the person dressed in such a manner is in control of their appearance and desires to exude such an image. Arguments can be made to ...

Black Gold Texas Tea Trevor MacKenzie Black Gold the Texas Tea In this paper I will touch on topics of oil prices, the demise and growth of oil companies large and small and international oil regulators, natural oil deposits and their locations and life expectancy, and the future of the oil industry and all it effects. I have chosen to write on this topic because of personal interest in the worlds biggest resource, oil. In past years I have thought of how the modern world revolves around certain elements and ideas, one of these is oil. I wanted to try to get answers to questions I have had about How long can we keep extracting oil from the Earth? and How will people overcome a worldwide comp ...

... inclination i of the system, and several important things can be calculated. The mass function f(M) = M2^3 sin i / (M1 +M2)^2 gives a relation between the masses of the two bodies, and the semi-major axis a1=AM2/(M1+M2)^2 sin i (where A is the separation of the centers of mass) gives the size of the orbit, which can also be related to the rotational velocities of the stars. A spectroscopic binary with no visible companion would be a candidate for a black hole, and if the dim star's mass is determined to be greater than that of the visible star, it would be a promising candidate. However, this method consists of many uncertainties. Although there were no hard cases for black holes any sci ...

Blood is a fluid substance that circulates in the arteries and veins of the body. Blood is bright red or scarlet when it has been oxygenated in the lungs and passes into the arteries; it becomes bluish red when it has given up its oxygen to nourish the tissues of the body and is returning to the lungs through the veins and the tiny vessels called capillaries. In the lungs, the blood gives up the carbon dioxide wastes it has taken from the tissues, receives a new supply of oxygen, and begins a new cycle. This movement of blood is brought about by the coordinate activity of the heart, lungs, and blood vessels. Blood is composed of a yellowish fluid, called plasma, in which are suspended the mi ...

Business Evaluation Business evaluation The subject that I interviewed was Mike Anderson from Allstate Insurance. Mike is an agent who owns his own office and has his own employees but at the same time is also an employee himself for the Allstate Corporation. The nature of Allstate is the sales of different lines of insurance policies. Mike's office is very service oriented although they are in the sales business. He classifies his office as a retail business with the explanation that he is selling something that is not provided directly by him, rather by the company, and because what he is selling is being bought. Allstate is a company that has many people that work for it. Each of these em ...

Cancer Treatment There are many ways to treat cancer. In fact, when you enter "cancer treatments" into any web browser you will find millions of web sites on how to treat cancer. Some examples of these treatments are chemotherapy, oxygen therapy, vitamin D therapy, food therapy, immunotherapy, and many others. Certain types of therapies go with certain types of cancers. For example, vitamin D therapy goes with breast cancer and immunotherapy goes with colon cancer. Cancer has taken the lives of millions of people and I believe it is important to inform people of what treatments are circulating in the medical profession. The human genome project's goal is to map and sequence the tens of thous ...

Countering Terrorism Countering Terrorism There are currently more than 1500 terrorist organizations and groups being monitored in the United States. Terrorists by definition kill people and destroy property in order to advance a political agenda. We must make every effort to protect American citizens from these attacks. In the future that will require both state of the art measures to monitor terrorist activities and the movement of materials used for these activities, but also response scenarios in the event of an actual incident. The United States has consistently set a good example of no negotiations with terrorists and attempting to bring alleged terrorists to trial. We need to support ...

... lled. We memorize information so much more easily if we are able to see the whole picture and understand it to the extent that we are able to organize it. Organizing material makes learning easier because by understanding something it reduces the amount of information to be remembered. That is because we think of the elements of an idea as constituents in an interconnected whole. We then enter the package whole into memory rather than it's separate components. By integrating and unifying the information with past knowledge it reduces the effort needed to remember whatever information needs to be learned. With this knowledge at hand I have finally answered a question I have tormented my g ...

Ethology The biological study of animal behavior is called Ethology. All behavior is a reaction to a stimulus. John B. Watson influenced animal behavior in the twentieth century. He published a book in 1924 called Behaviorism. Jakob von Uexkull and O. Heinroth started a school that taught about animal behavior. There are two categories of animal behavior: "genetically determined" or "environmentally determined." Animal behavior is the different ways that animals do different things, such as hunting. An example of this would be how a lion hides in the grass to hunt their prey. Some of these are instinct or they must learn from their parents or the hard way. Examples of animal behavior When a ...

Evolution Of Labor Unions What is clearly evident is that the working people of America have had to unite in struggle to achieve the gains that they have accumulated during this century. Improvements did not come easily. Organizing unions, winning the right to representation, using the collective bargaining process as the core of their activities, struggling against bias and discrimination, the working men and women of America have built a trade union movement of formidable proportions. Labor in America has correctly been described as a stabilizing force in the national economy and a bulwark of our democratic society. Furthermore, the gains that unions have been able to achieve have brought ...

Freedom Versus Safety More Freedom or Safety -- What Would You Choose? Where does one draw the line between individual freedom and the safety of the community? Recent tragedies in high schools around the country show a great increase in teen violence. The worst part it that these acts of violence arent just fights and shootings; they are planned mass murders in our high schools. No more poignant example brings into focus the question of individual freedom and safety for the school community. Does individual freedom mean that students can bring whatever they want, including weapons, to school? Does safety of the school community mean that students must be searched or go through metal detector ...

Georges Charpak Georges Charpak, a French citizen, was born on August 1, 1924 in Poland. Charpak's family moved from Poland to Paris when he was seven years old. During World War II Charpak served in the resistance and was imprisoned by Vichy authorities in 1943. In 1944 he was deported to the Nazi concentration camp at Dachau, where he remained until the camp was liberated in 1945. Charpak became a French citizen in 1946. He received a Ph.D. in 1955 from the College de France, Paris, where he worked in the laboratory of Frdric Joliot-Curie. In 1959 he joined the staff of European Laboratory for Particle Physics at CERN in Geneva and in 1984 also became Joliot-Curie professor at the School o ...

Gun Laws States from Michigan to Nebraska to California, as well as the federal government, are considering new rules on letting law-abiding citizens carry guns. Does allowing citizens to carry concealed handguns deter violent crimes? Or does this cause otherwise law-abiding citizens to harm each other? Thirty-one states now have guaranteed their citizens the right to carry concealed handguns if applicants do not have a criminal record or a history of significant mental illness. So what have the results been? The numbers tell the story Using the FBI's crime-rate data for all 3,054 U.S. counties by year from 1977 to 1992, I co-authored a study in the January 1997 Journal of Legal Studies. We ...

... ning guns is not the answer to solving school violence. Large inner city schools have metal detectors at the doors but sometimes that doesn't stop all the potentially harmful objects from entering the school. It is a step in the right direction but not all schools need them so desperately or can't afford them. For now, we need to try to deal with it as it comes and maybe educate the teachers on what to do in different types of terrorist attacks. Attacks on abortion clinics are terroristic too. I am not going to get in hard on my beliefs because that is not the topic and it could be a whole other paper in its self. I want to say that I am firmly against the idea of abortion and my views m ...

INDUSTRY STUDIES QUESTION 1. (a) Student -centred learning could be described as student-independence learning. The student has to some degree the ability to choose the time and place of study, the methods and order of studies and can vary his pace of study as well as the length of his studies to suit his needs. Student-centred learning puts the students needs to a large extent first. Having a learner-centred approach gives students options in the pace of study, the method of delivery of courses (e.g satellite, mixed mode, tutorial support classes), order of study, composition of courses to suit individual needs. Open by dictionary definition means: unconfined, without barriers, accessible. ...

Cadmium represents approximately 0.009% of a PC by weight 16. Based on the total number of disposed PC's in Canada in 2000, this translates to 2.0 tons of cadmium.
