Abstract This paper discusses white as a color and more specifically, white light. The paper describes the qualities of the color white and the multifaceted nature of existence and the way that it relates to significant chemical alterations in nature. The paper goes on to discuss the importance of white light to the scientific understanding of reflective light and the dimensions of other colors.
From the Paper "Dimensions of the Color White Outline I Introduction. White as a color is not often considered to have many dimensions or properties that are significant to either science or society. While white may carry with it the concept of "purity", the color itself is multifaceted and related to significant chemical alterations in nature. White light has been especially important to scientific understanding of reflective light and the dimensions of other colors. Scientifically white must possess certain chemical compounds in order to exist, and in the field of psychology, white speaks to individuals through subconscious messages about the world they live in."

Abstract In this essay, the writer points out that soil bacteria control the course of nitrogen, carbon, and phosphorus through ecosystems. Soil samples were taken from established sites, which have undergone existing long-term manipulations of temperature, nutrient and light availability. The writer discusses that the soil samples were found to contain bacteria through testing and are being studied to determine whether treatments known to affect plant communities also affect soil microbial biomass, activity, gene expression, and community composition as measured by terminal restriction fragment length polymorphisms.
From the Paper "Soil is an intricate and active biological system, and at times it is difficult to determine the composition of microbial communities in soil. Yet, the study requires a wide variety of methods, which includes methods of extracting DNA from soil suitable for PCR amplification to monitor GM rhizobia and extracting mRNA directly from soil to use in gene expression studies. Hydrocarbons seem to be a contaminated factor when isolating the soil samples in determining bacteria characterization. "Bacteria were isolated from contaminated soil with the media indicating several homolog similarities (researched the possibility of several bacteria names through DP database as determined by the program SIMILARITY_RANK (10)"."

The Analysis of Glass Fragments, 2005. This text describes the glass analysis relevant in forensic science. The classical approach of glass analysis (measurement of refractive index) proved. 2,025 words (approx. 8.1 pages), 5 sources, $ 80.95 »
Click here to show/hide summary
Abstract This text describes the glass analysis relevant to forensic science. The paper examines how the classical approach of glass analysis (measurement of refractive index) proved to be unreliable method for a glass sample manufactured after 1980. The most recent approach uses chemical analysis to determine trace and ultra trace elements in glass. The paper analyzes two modern methods of chemical analysis.
From the Paper "Glass fragments belong to the group of trace evidence, i.e. very small amounts of material that can link an item on which it was found with an otherwise unconnected source of it elsewhere. The traces of glass are frequently encountered on the crime scene. If the glass breakage occurred, the glass fragments are likely to be found on the objects or persons present at the scene. They can often be easily spotted because they are shiny particles (of course in the case of coloured glass the recognition is easier). Additionally they have irregular shapes hence they tend to remain attached to the material longer than the trace evidence with smooth surfaces."

Air Canada, 2005. A discussion on the deregulation of the airline industry in Canada. 2,250 words (approx. 9.0 pages), 2 sources, $ 89.95 »
Click here to show/hide summary
Abstract This paper answers three questions. The first question deals with deregulation and its effects on Air Canada The second question looks at the history of the industry and the future. The last question looks at interest groups.
From the Paper "Regulation is defined as, "an order issued by an executive authority of a government and having the force of law" (Anonymous 1999: 441). Deregulation is simply the process of removing regulations within an industry. Both regulation and deregulation have been and continue to be very important in Canadian industries. Traditionally the Canadian government has favoured regulating certain industries in order to protect them from competition from more competitive foreign competitors. This is the entire idea behind a Crown Corporation. "

Click here to show/hide summary
Abstract This paper focuses on a study that was conducted regarding the browning agents in mei liquor. It looks at how the study was the first in the research regarding fruit related liquors and was begun to determine the cause of discoloration in mei liquor after shelf life.
From the Paper "Shih-Chuan Liu, Hung-Min Chang, and James Swi-Bea Wu completed their research article, "A Study of the Mechanism of Browning in Mei Liqueur Using Model Solutions" for National Taiwan University in December 2002. The study focuses on the components of the browning agents in mei liqueur, and expands to consider discoloring in fruit liqueurs. The research is of scientific important because it aids in clarifying the elements in some acidic fruit products that cause the liqueur to become discolored over time. Determining whether this discoloration is caused by the preparation process, the elements within the main ingredients, or from contamination of the product is essential for food safety. Furthermore, the research benefits science in that it provides answers to inquiries relating to browning causes in liquor products for public knowledge, and product information."

Pesticides and Effects on Humans, 2005. This paper discusses pesticides and their effects on the human immune system. 900 words (approx. 3.6 pages), 4 sources, $ 35.95 »
Click here to show/hide summary
Abstract This paper discusses that science has proven that pesticides pose two separate yet related dangers. The writer notes that pesticides are everywhere in our environment and that children especially are exposed to them every day in their food and in the surfaces they touch. The writer points out that firstly, they cause various health problems, including cancer and that secondly, they attack the immune system. Thus, the writer shows that they not only create challenges for the immune system but they also make it unable to do its job.
From the Paper "Pesticides have served mankind since ancient times, mostly as insect repellents. More than fifteen hundred years before Christ, the Egyptians used natural preparations to get rid of fleas in their households. In the 1930s, a whole range of new products was developed to destroy or repel insects, rodents, fungi, weeds and other unwanted organisms. The most notorious of these new pesticides was DDT."

Xanthine Oxidase, 2005. This paper examines the substance xanthine oxidase and looks at its potential functions in biology and medicine. 2,700 words (approx. 10.8 pages), 10 sources, $ 106.95 »
Click here to show/hide summary
Abstract This paper briefly explores the xanthine oxidase enzyme, its impact upon the body, and the research which has explored how and why this enzyme functions. The writer discusses that due to the easy accessibility of xanthine oxidase in cow's milk, this enzyme has been the subject of numerous studies for more than a century. However, the writer points out that despite this heavy level of scrutiny, xanthine oxidase is still not fully understood. This paper explores the literature which reflects upon past studies into xanthine oxidase and current research and potential applications for this substance.
From the Paper "The basic construction of xanthine oxidase has been extensively documented and is understood: This enzyme functions as a dehydrogenase which converts hypoxanthine to xanthine, and converts xanthine into uric acid. The conversion of hypoxanthine to xanthine alters the hypoxanthine, a purine, into a degraded purine, which then is further degraded into uric acid which is then passed from the system. Granell et al stress that: Under [normal] physiologic conditions, the enzyme exists mainly as xanthine dehydrogenase (XDH), a form that uses NAD^+ as electron acceptor. Nevertheless, under certain circumstances, XDH can be converted to xanthine oxidase (XOD) by limited proteolytic cleavage. XOD uses molecular oxygen as electron acceptor and consequently generates the superoxide anion, a molecule that participates in the generation of other reactive oxygen species including hydrogen peroxide, hydroxyl radical and peroxynitrite."

Matrices, 2005. This paper present a study of the theory of matrices that includes its history, development and uses. 900 words (approx. 3.6 pages), 2 sources, $ 35.95 »
Click here to show/hide summary
Abstract This paper discusses the theory of matrices, how it was developed, how it changed, some of the applications for which it has been used, and other aspects of the issue. The writer notes how the underlying ideas are ancient and began with the Babylonians and Chinese and then resurfaced in the seventeenth century with the world of Cayley and others. Further the writer points out that the theory of matrices has led to uses in physics, chemistry, and economics as well as mathematics.
From the Paper "Matrices are a means of visualizing mathematical concepts and relationships in graphic form. A matrix is a rectangular set of elements viewed as a single entity, identified by the number of rows and columns of which it is made. Matrices can be added or multiplied on the basis of an algebra of matrices, and one application of this sort of operation is seen in vector analysis and in the solving of systems of linear equations. The basis for the matrix is found in the Cartesian system of Rene Descartes, whose contribution to mathematics was in the development of analytical geometry, closely tied with the development of the Cartesian system of mapping on a grid or graph, for Descartes saw that a function or polynomial can be represented graphically by points."

Hydrogen Fuel, 2005. This paper discusses hydrogen and examines its use as an alternative source of fuel. 900 words (approx. 3.6 pages), 6 sources, $ 35.95 »
Click here to show/hide summary
Abstract This paper concerns the alternative fuel hydrogen. The writer notes how this fuel is produced and looks at some of the problems of making it practical for use in automobiles and other vehicles. The writer explains that storage is a major issue, because hydrogen takes up four items the space of a comparable fast energy source. Some of the research being conducted to correct this situation is noted, including new materials for storage.
From the Paper "There are many reasons to embrace the demand for alternative fuels. The current state of the world's ongoing energy crisis, of the demand for fossil fuel and of the constant fighting over oil in the middle east, are all current events that are related to oil and fuel. However, we should also look to the future for the true reasons for using alternative fuels. The emissions from power plants, refineries and automobiles are causing global warming and irreversible damage to the ozone. This is why it is so important for scientists, engineers and researchers to break down the fossil fuel barrier and replace it with alternative fuels, one of which is hydrogen."

"Food for Sloth" by Carol Krenz, 2005. This paper discusses the article "Food for Sloth" by Carol Krenz, which discusses the way carbohydrates and sugar effect the brain. 1,125 words (approx. 4.5 pages), 1 source, $ 44.95 »
Click here to show/hide summary
Abstract This paper explains that Carol Krenz' research explores the way sugar and carbohydrates stimulate differing parts of the brain. The author points out that, by realizing the soothing powers of both sugar and carbohydrates, there can be little doubt that both offer a solution to depression in the winter. The paper relates that, by keeping a balance of both of these necessary dietary factors, relief from depression can be found without hazardous health problems, which each one may provide singularly.
From the Paper "The article "Food for Sloth" by Carol Krenz begins with an argument that presents the similarities between comfort' foods and hibernation foods. This manner of food related analysis present the dietary and psychological process that leads to excessive sugar and carbohydrates in the winter months. The beginning pars of the article tell how human beings have a tendency to eat more sugars due to the normative depressive states that occur between December and March. The article then begins to discuss the indifference between comfort foods and hibernation that exist, but not without the 'poisoning' that sugar and carbohydrates can impart on the human body in a singular manner."

Desalinization, 2005. The paper discusses desalinization as a means of meeting the world demand for water. 2,475 words (approx. 9.9 pages), 8 sources, $ 97.95 »
Click here to show/hide summary
Abstract This paper examines desalinization as a process of removing salt from sea water so that it can be used for drinking, watering crops or industrial processes. The author points out that, because water is so important to the very existence of life, the methods used in its allocation and distribution can't be ignored. The paper looks at two methods of desalinization.
From the Paper "Water is a very valuable resource. Water is essential for every organism on the planet in one form or another. Human's are no exception to this rule. For example Stephen Brooks and Lydia Milijan in Water Policy say, Water is essential for human life. We require water to sustain our lives, and about 83 per cent of our blood is water. Water helps digest our food, take in oxygen, transport body wastes, and control body temperature (Brooks and Milijan 262). The fact that water is so important to the very existence of life means that the methods used in its allocation and distribution can't be ignored."
