Abstract
This paper examines three issues concerning the metabolism of ethanol, one of the major forms of alcohol, and then compares how the ethanol found in beer is metabolized to how the ethanol found in the over-the-counter cold suppressant, Nyquil, gets metabolized.
From the Paper
"Although this research project concerns the metabolism of ethanol, one of the three major forms of alcohol, the major topic will discuss three distinct yet similar issues concerning the metabolism of ethanol. The first issue is the means by which the liver metabolizes ethanol the second and third issues discuss the variances involved when comparing how ethanol found in beer is metabolized with the ethanol found in one of the more popular cough suppressants. For simplicity and clarity the cough syrup being used in this study is Nyquil...."

Abstract
This paper explores the progress of ethanol as a fuel derived from renewable crops. It particularly focuses on cellulosic ethanol, which can be produced from agricultural, municipal and forestry waste, corn stalks, sawdust and waste paper. The paper discusses all of these options, as well as the viability of being able to produce enough to significantly reduce the United States dependence on foreign oil.
Table of Contents:
History of Ethanol
Current Uses of Ethanol
Arguments For and Against Ethanol as a Major Alternative Fuel
Retooling for Ethanol
Conclusion
From the Paper
"United States would require an "area of energy crops as large as the current area of food crops grown in the United States. Additional land use of this magnitude would be staggering and contentious" (p. 18). According to Haroon S. Kheshgi, an engineer for EXXonMobil Research, nothing will replace petroleum because to run an average U. S. car with corn-derived ethanol for a year would require 14 acres of cropland--about nine times more land than is needed to feed one person the same length of time. Aside from the fact that Kheshgi is invested in the oil industry, this argument, does not consider the use of agricultural waste products as the source or use of the by-products of distilling ethanol. If the land were still used to grow food, and the wastes were used for ethanol, benefits to the environment would be great. Also, if hydrogen power is the ultimate goal, ethanol could be "part of a transition strategy for shifting from today's internal combustion engine technology to tomorrow's hydrogen-based engines" (Issues in Science & Technology, 2002, p. 17)."

From the Paper
"Not only is petroleum a depleting resource, but vehicle emissions running on petroleum have created a pollution problem in the United States and most of the industrialized world. These emissions have increased the green house gases in the earth's atmosphere and in turn have led to global warming. Billionaire businessman Ted Turner has helped bring this issue to the forefront of the energy debate, stating, "'I think dealing with climate change is going to be the biggest single challenge humanity has ever faced, and we're facing it now'" (Dittrick, 2007, p. 26)."

Abstract
This paper discusses the production of bio-ethanol fuel as an alternative to fossil fuels, in Brazil. The paper begins by giving a summary of the political and economic background of Brazil and goes on to describe why the production of bio-ethanol has been so successful in Brazil. The paper presents the pros and cons of bio-ethanol production and concludes that, at this stage, the advantages of producing ethanol for fuel use appear to outweigh the disadvantages.
From the Paper
"Overall, the advantages of producing ethanol for fuel use appear to outweigh the disadvantages, which at this stage, are believed to be manageable. The first benefit is the decrease of the net output of the greenhouse gas carbon dioxide in the atmosphere, since the amount of carbon dioxide released in the manufacture would be cyclically absorbed in the production of the new fuel crops (Wikipedia 2006). The burning of fossil fuels brings up massive amounts of carbon dioxide into the atmosphere without creating damage. But this advantage can be derived only from agricultural ethanol, not petroleum ethanol. It is also assumed that production processes, like distillation and fertilizer production, would not exact large amounts of energy and done without using fossil fuels (Wikipedia)."

Abstract
Discusses benefits of ethanol as a renewable fuel & valuable resource. Fuel Cell technology. Internal combustion engine & exhaust problems of air pollution. Expansion of ethanol use. "Flex-fuel" vehicles. How fuel cells work. Effect on environment. Need to use ethanol as a fuel resource, not as a waste product.
From the Paper
"Ethanol, once considered a hazardous waste product of many industrial processes is no longer viewed in that light. Now, it is a valuable resource, much sought after, particular in fuel cell technology (Ethanol as a renewable fuel, 2000). The internal combustion engine gains its energy from the heat released during the combustion of the non-reacted working fluids, the oxidizer-fuel mixer (Britannica, 2000). The process occurs within the engine, and is a part of the thermodynamic cycle of the device. Useful work generated by the internal combustion engine results from the hot, gaseous products of combustion acting on moving surfaces of the engine, such as the face of a piston, a turbine blade, or a nozzle.
The most common example of the internal combustion engine, the intermittent combustion engine, is characterized by periodic..."

Conclusion
From the Paper
"Pearlstein, the author of the article, reports that the price for ethanol has reached an all time high of $2.90 per gallon which is twice as high as a year ago. With the manufacturing cost around $1.25 per gallon, the operating margin exceeds 50%. Ethanol is a colorless, volatile alcohol derived from the fermentation of grains and sugars or by the hydration of ethylene. Ethanol can serve as an environmentally friendly substitute for gasoline. Many oil companies are exploring options for production of ethanol to mix it with gasoline to reduce costs. Data indicate that adding ethanol to gasoline would reduce current prices at the pump by 30 cents per gallon (Donaldson, 2006 12)."

Abstract
The paper discusses how economic issues, such as escalating oil prices, and environmental problems, such as global warming, can potentially be addressed by the ethanol market. The paper looks at arguments for and against this source of energy. The paper maintains that global research and development are necessary in order to determine the true benefits and dangers of replacing conventional fuels with ethanol compounds.
From the Paper
"According to Eckhart, there are three main drivers for the general renewable energy market, and for the ethanol market specifically. These include environmental concerns, economic factors, and national energy consumption trends. In terms of the environment, air, land and water pollution is fast becoming a crisis. According to environmentalists, no time can be wasted to research renewable energy sources. The environmental driver is likely to become increasingly urgent over the next decades, increasing the need for renewable and cleaner energy sources."

Abstract
The paper discusses the possibilities of using ethanol as an alternative fuel in vehicles. It examines the chemical composition, procedure of preparation and blending, as well as the pros and cons of using the substance, from an economic, environmental and practical point of view.
From the Paper
"Any biological feedstocks that contain certain amounts of sugar or any material that can be converted into sugars such as cellulose and starch can be used to produce ethanol. Some examples could be sugar and sugar cane. Starch containing feedstocks such as corn can also be converted into sugar. A plant is significantly composed of a substance called cellulose which is a form of starch that can also be converted into sugar but with greater difficulty compared to the regular starch."

Conclusion
From the Paper
"Hydrogen is one of the many competitors looking to replace gasoline at the pumps. It has many advantages over an ethanol fuel, hydrogen requires less heat to ignite than ethanol, which means that more energy is used for powering the vehicle as opposed to igniting the fuel. (2006) In addition, its flame gives off much less radiant heat than a hydrocarbons flame, yet the flame is just as hot. (2006) Hydrogen's energy produced per unit of mass is larger than that of hydrocarbon fuels by a factor of 2.8. (Snyder, 2006). The higher specific energy means that the car can produce more heat energy for the same amount of fuel mass."

From the Paper
"In patients with acquired immune deficiency syndrome (AIDS), also affected by myocardial infarction or undergoing surgical procedures, the severity of the several complications that could develop is associated with acute ischemia reperfusion injury (Redmond et al., 2000, Van Tol and Hendricks, 2001). This makes it relevant to target an efficient potential treatment method in myocardial ischemia reperfusion injury, with particular reference to patience with AIDS. Moderate consumption of ethanol is known to offer myocardial protective effects (Sacco et al, 1999). Furthermore, Miyamae, et al, 1997, suggest that regular ethanol consumption could also offer protection in ischemia reperfusion injury. "

Abstract
This paper is a technical report on a laboratory experiment on surface tension measurements using the Du Nuoy ring. Samples are pure water, ethanol solution, and 1.5N NaCl. Calculations for the correction factor and other necessary values are included in the discussion.
From the Paper
"The Du Nuoy ring is the most commonly used apparatus for surface tension measurements. The group used pieces of paper to determine the weight needed to depress the lever arm to zero. For the experiment proper, the ring was thoroughly cleaned and flamed to red heat for a few seconds. The vernier was turned to zero reading and the lever arm made to just touch the zero indicator. The ring was made to contact the surface of the liquid and was carefully submerged until good contact is established. This was then slowly recovered from the liquid by careful downward movement of the platform and of the thumbscrew. It is important that the lever arm is kept at the zero indicator until the ring is detached from the liquid."

Abstract
The paper discusses how, with the problems in foreign policy and the volatile situation in the Middle East, it is important to reduce the U.S. dependency on foreign nations for oil with regard to vehicle use. The paper maintains that the time has come to use alternative means of fuel and suggests ethanol technology for transportation needs. The paper explains that supporters of ethanol technology believe the effort is worth the end result, since the use of ethanol is environmentally friendly and will provide business for the domestic farmer because it uses surplus agricultural crops.
From the Paper
"As gasoline prices continue to rise and Americans become increasingly frustrated at the pumps attention is turning to finding a way to decrease US dependency on foreign nations for oil. Gasoline is at an all time high. The nation is at war and an underlying concern about this war as well as other conflicts within the Middle East is the dependency on oil for vehicle use that the United States has allowed to occur. With the problems in foreign policy, and the volatile situation in the middle east it is important to reduce the US dependency on foreign nations for oil with regards to vehicle use. The time has come to improve and use the ethanol technology for transportation needs in America."

From the Paper
"It is well known that most of the medicines in the world are derived from plants. For many years plants have been investigated in an effort to help boost the human immune system, and accelerate the recovery process from infectious diseases. Panax ginseng is a notable traditional herbal medicine that has been utilized by the Chinese for thousands of years [1]. Although there have not been extensive studies of ginseng's benefits to the immune system [3], the plant's capacity on the function of leukocytes has been under study [3]. The use of ginseng as a medicine has been gaining popularity in the west [4], much of this is because of studies that have linked it to prevention of cancer [5]. It is believe that much of the beneficiary components of ginseng are because of ginsenosides, a various group of steroidal saponins, which are able to target and affect a large number of tissues [4]."
