This paper discusses how "green" cars are designed to reduce emissions, thereby lessening problems of ever-increasing air pollution, which causes asthma and lung cancer.
Abstract This paper explains that "green" cars are vehicles that drive just like any other vehicle, except they are at least 90% cleaner-burning than the standard vehicle on the road, thereby emitting a lower amount of pollutants into the air. The author points out that the most popular models, which are mass-produced on the market right now, are called 'hybrids' because these vehicles have hybrid motors that use a mix of a gasoline engine and electric motor with a large battery that keeps energy flowing to the electric motor with no need to "plug" it in to recharge; when the cars get to "cruising" speed, they switch to the electric motor, letting it do most of the work. The paper stresses the financial benefits, which add to the environmental and health reasons to buying a "green" car; the actual purchase price does not vary too much from the regular gas-burning model, and the savings annually in gas can be tremendous.

From the Paper "While companies like Honda and Toyota are more aggressively bringing hybrids to market, GM decided last year to focus its most advanced hybrid technology on its largest, least-fuel-efficient, high-volume vehicles models. It plans for them to reach showrooms in 2007. The Toyota Prius and Honda Civic Hybrids have been rated at averaging 60 miles per gallon, which has captured the attention of many producers, designers, engineers and consumers. This is encouraging because automakers are taking notice of the problems with our environment and actually coming up with ways to help fight for the cause."
Abstract This paper explains, starting from the basics, what genetic engineering actually is, and how it is carried out. It details its uses in society and explains the risks involved and how to overcome them. Ethics and social values are included in the discussion.

From the Paper "Restrictions have become less severe over the years, and genetic engineering is being applied more and more as public approval is constantly being sought. Nevertheless, this does not diminish the potential dangers of creating transgenic organisms. For example, consider the use of genetically modified organisms - GMO's - in the general environment, such as crop plants. Can such organisms be used safely? Suppose the pollen of these plants are transferred to wild relatives, thus injecting the gene into a different species. These plants may now act as weeds, and if the crop plants were engineered to be herbicide-resistant, then the weed will be similarly so. When a new type of oilseed rape resistant to the herbicide Basta was produced by the Belgian company 'Plant Genetic Systems' in 1994, there were concerns that rapeseed would act as a weed in hedgerows and would be impossible to control with Basta."
Abstract This paper examines how the various forecasting methods have their differences and similarities. Some are based on hard data, such as past sales figures and surveys, while another may simply use assumptions. It looks at how, with the ever changing market trends careful considerations must be given to any style of forecasting that is used and how the type of forecast method used depends on which area of the market a company is in.

Conclusion
From the Paper "The clothing industry utilizes forecasting methods that contain both assumptions and past data. Clothing styles change on a regular basis and rely on one constant, what is pleasing to the public's eye. Over the past few decades clothing styles focus on the amount of skin that is reviled and how the cloths show off the body's figure. Many people feel that wearing a certain outfit they saw in a magazine or commercial will look just as good on themselves. In other words: the clothes make the person. Some people believe that people who are obese or have very bad skin should not be wearing garments such as mini-skirts, plunging neck lines, shorts or mid-drifts. "
Abstract This paper explains that, to reduce America's dependence on foreign oil, it is necessary to phase out the conventional internal combustion engine (ICE) gasoline engine; however, for now, gasoline must continue to be a widely used fuel in order to keep the gasoline industry of America strong. The author points out that, as oil prices continue to rise, hybrid automobiles (gas engine with electric motors complimenting them) seem to be the near-term solution. The paper relates that the next viable solution to the pollution problem posed by ICE is hydrogen (H2) and fuel cell technology; a fuel cell combines H2 and oxygen to create power through the by-product of this chemical reaction without the pollution problem.
From the Paper "Another way to save fuel with out using new engine technology is described in Wald's work on pg.1-2, and was developed by the EPA. It uses current engines to pressurize a hydraulic tank to 5,00psi.. The built up pressure is then used to drive a turbine, which drives the wheels. Lab tests show a 60-70% gain in fuel efficiency. This technology is currently in use by John M. Hewitt of Memphis Tennessee. John is using a Chevy s-10 pickup engine (less than 100hp) to pressurize the tank and is getting better than 100mpg. Ford has said they are working with the EPA to make a SUV with this technology."
From the Paper "Why is human cloning viewed as a bad (unethical) thing?? The only thing that is holding the possibilities back is the fact that some people, actually a lot of people, do not approve of cloning in the least bit. It is stated that "one (a clone) will lose the sense of human possibility in freely creating one's own future" (28), constantly haunted by their earlier twin. Also argued by the Nation Bioethics Advisory Committee is the fact that cloned children have a high chance of low self esteem, wondering their value because they were cloned instead of conceived. On page 21 in the book, it states some of main benefits. The biggest benefit is the fact that people can be cloned, and the embryos can be frozen and gestated for organ harvesting. This would be a huge advance in science, as many people in need of organ transplants will not get them and will die. With organ harvesting, there could be an unlimited supply of "spare parts" to increase the length of life. There is a possible legislation of using cloning as the first step to cure Parkinson's disease.
Abstract This paper differentiates between the dangerous slab avalanche, and the often harmless powder avalanche. It explains what weather conditions contribute to the worst avalanches. It also examines the significant impacts avalanches have on the environment and shows certain preventative techniques to protect and limit the damages and deaths caused by avalanches.
From the Paper "There are two types of avalanches; powder avalanches and slab avalanches. In very cold, dry weather, light powdery snow grains don"t stick together. If this snow is pushed down the slope, it forms a powder avalanche, which swirls along like an enormous white cloud. Normally these avalanches aren"t that dangerous as there isn?t much snow in them, they are also easy to get away from, most of the time. The slab avalanche is the most dangerous, and causes the most damage. A slab avalanche starts off as a solid chunk of frozen snow about the size of a soccer field and about 30 feet thick ( McClung, David and Schaerer, Peter, 129). It usually forms on sunny days that are followed by frosty nights and snow that melts and freezes again. These slabs are cracked, commonly by the edge of a ski, and break into many different thick pieces that haul down the slope, taking out whatever is in its path."

Abstract This is a detailed descriptive, persuasive paper about the effects of genetically modified crops. The author discusses genetic engineering and clearly defines many difficult biological terms, and how the Food and Drug Administration plays a major role in the legalization of genetically modified crops.
From the Paper "Genetically engineered crops have killed dozens of people throughout the United States of America and Europe , and have harmed thousands of others. Governments of the world should outlaw genetically modified agricultural products to ensure that no other lives will be susceptible to the same type of danger. Scientists first designed genetically altered crops to resist herbicides. Genetically modified crops were also not intended for human consumption. In fact, they were intended for better yields, resistance to herbicides, and cheaper feed for livestock, such as cattle, sheep, poultry, etc. The FDA is now investigating genetically modified crops to see if they should ban them in the United States of America ."

Abstract In this paper the author takes an in-depth look at the history of engineering education and the ways that engineering, and engineering schools, continue to improve life. The author investigates why engineering schools began to assume greater importance in the second half of the 19th century in the United States and considers the historical context of engineering and engineering education.
From the paper:
?As people's understanding of the ways in which the physical world is constructed increased over time, engineering developed a number of subfields that addressed the various problems inherent in different materials and different applications. Thus developed the traditional four primary engineering subdivisions: civil, mechanical, electrical, and chemical. Over time specific educational programs would develop to train engineers in each of these subfields.?

Abstract This paper discusses in detail the safety of the Suburban Utility Vehicle (or SUV). The author uses the science of physics and engineering and the relationship between a car's relative mass and center of gravity to understand to understand the problems. The author states that increasing the track width is the only way to make the vehicles more stable but that may modify the appearance of the car.
From the Paper "What can be done to remedy these concerns over the Wrangler's design? To answer this question, one must do more than simply understand more about the safety features of this particular vehicle or of SUVs in general. One must turn to the science of physics and engineering and the relationship between a car's relative mass and center of gravity to understand what the risks are for each vehicle and how best to potentially remedy those risk. Or, to put the question in another way, if Einstein were an auto mechanic, what type of Jeep Wrangler would he like to be riding in? How might he modify the vehicle's design?"
Abstract This paper introduces and discusses the atomic bombs that were dropped on Japan to end World War II. It examines how the bombs were developed, the use of the bombs and what their effect has been on the world.
From the Paper "Numerous scientists contributed to the development of the atomic bomb with discoveries in several areas, such as physics, mathematics, radium, and more. Albert Einstein's E=mc2 helped physicists discover the speed and mass of atoms, and Eve Curie's discovery of radium gave them the material to make the bomb. The discoveries went on and on for several decades, and eventually, scientists realized they could create a devastating weapon."
Abstract The treatment of wastewater is divided into three main categories: Primary treatment, secondary treatment and tertiary treatment, where each stage contains several steps. This paper examines this purification and treatment process and explains each stage step-by-step.
From the Paper "The primary treatment stage involves the removal of physical contamination which includes grit, grease and solid particles. The first stage in this is a screening process, which filters our large particles. The next stage is grit removal, this is a settling stage where grit is allowed to settle out of the water under low flow conditions (Manahan 226). The final stage of the primary treatment is grease removal, which is achieved by allowing the wastewater to settle, with the grease materials floating on top. This top layer is then scraped off."
From the Paper "The Technological Development & Application of the Machine Gun
This research traces the technological development and application of the machine gun. John Ellis wrote The Social History of the Machine Gun from a general perspective of the development and application of technology. Ellis worried, however, because machine guns, to use his words, head become an "indispensable aid" not only to soldiers and the police, but also to terrorists.
For better or worse, the technology of the machine gun is now a part of human existence. The insinuation of machine technology into human society began in 1884, when the first effective fully automatic machine gun was developed and patented in the United States by Hiram Maxim. Multi-barreled weapons, such as the Gatling Gun, had been used earlier in the..."
Abstract This paper argues for and against the use of genetic engineering from a number of perspectives. It shows that, even though God has given man the knowledge to manipulate genes in such a way as to eliminate almost any blemish, the question remains whether this is the right thing to do. The paper mentions that, on the one hand, the scientific potential is mindboggling; but on the other hand, many fear that the power of eliminating certain types of genes, could be blown out of proportion.
From the Paper "The alteration of the genetic structure of any organism is done by means of Genetic engineering that provides characters beneficial or pleasing to the individual performing the alternation. In other words it is a treatment of the DNA or RNA pool (Sarah. 2002). For instance, the most greatly well known example of genetic engineering is the sheep Dolly that was cloned in the year 1996. Here, in order to create Dolly, the scientists took out cells from the udder of a pregnant, six year old ewe and then these cells were put into not related host eggs that had their DNA separated. Thus, as an alternate of creating one fertilized egg, a reproduction or a duplicate of an adult animal was made (Sarah. 2002)."
