Abstract This paper describes a chemistry experiment exploring the carbonate/bicarbonate buffer system. The paper explains how the testing of the buffer was conducted and discusses the reaction of the individual ingredients, sodium carbonate and sodium bicarbonate, to the addition of acid or base. The paper also explores the reaction of the combined solution to acid and base.
Abstract This paper explains the buffer systems in the human body. It specifically focuses on the role of the buffer systems in maintaining proper body pH. The paper explains the effect on the bodily systems if changes occur to shift the balance of acid-base systems to a range that is out of the norm. The paper looks at various cations and ions in the body and their function.

From the Paper "Buffers and buffer reactions are one of the most important reactions in the human body. The body has a limited tolerance for changes in pH. The ability to maintain proper pH can present as a primary cause of concern, or it can represent a secondary complication. The most common problem associated with pH shifts are heart arrythmias and pulmonary problems. The six chemicals discussed in this research are the most important ones for maintenance of proper pH. However, there are many others that play a minor role. Understanding how the body maintains homeostasis is one of the most important concepts that any medical professional can know."
Abstract This study discusses the impacts of buffer widths of less than 50 feet on the populations of the common Pacific Tree Frog, Psuedacris Regilla. It looks at the problem at hand and discusses ways that this environmental concern can be solved.
From the Paper "Buffers are one way to protect the environment and demonstrate a commitment to conservation. They're best described as a small area or strip of land in permanent vegetation that's designed to slow water runoff, improve water and air quality, provide shelter and stabilize riparian areas. There are several types of buffers including wetlands and a Riparian corridor. Riparian Buffers are streamside plantings of trees, shrubs and grasses that can intercept pollutants from both surface and shallow groundwater before they reach a river or stream. Riparian buffers provide habitat for wildlife and enhance fish habitat by, among other things, reducing water temperature. Wetlands are lands on which water covers the soil or is present either at or near the surface of the soil or within the root zone, all year or for varying periods of time during the year, including during the growing season."

From the Paper "Modern personal computers are multi-user, multitasking systems. A user is no longer forced to wait for a given process to complete before attempting to start the next process. With the introduction of time slicing, the Central Processing Unit (CPU) of the computer can have its time divided up and shared between numbers of different processes. However the concept of multitasking brings with it the problems associated with managing the computer's memory. The operating system, in the case of this report, Microsoft Windows NT has the responsibility of distributing the available memory between applications or processes effectively, as well a number of other functions."
Abstract This paper answers some question on respiratory anatomy and physiology. It looks at lung function, how blood concentrations of CO2 affect blood pH, tidal volume, sensory receptors, and buffers.
From the Paper "When the diaphragm contracts it becomes flatter and drops and increases the volume of the thoracic cavity. The parietal and visceral layers of the pleura adhere to each other because of an attraction between the water molecules in the serous fluid between the two layers. This increases the volume of the thoracic cavity and causes the lungs to expand their volume. The intra-pleural pressure is less than the pressure within the lungs which also contributes to lung expansion. During labored breathing the external intercostal muscles and other muscles..."
Abstract This paper explains that Turkey's potential membership in the European Union (EU) underscores its role in the region and throughout the international community, especially as Europe becomes increasingly Islamized and as the unrest in the Middle East remains at a boiling point. The author presents, in addition to the literature review, case studies of the continuing unrest between the Palestinians and Israelis and the Danish religious cartoon controversy featuring pictures of the Islamic prophet, as examples of Turkey's increasing importance in the region and in the global geopolitical sphere. The paper states that international observers believe that Turkey represents the West's best chances for securing a mediating influence in the region and for developing a cultural, political, religious and geographic buffer between themselves and the increasingly hostile nature of many factions in the Middle East. The paper includes several long quotations.

Conclusion
From the Paper "For example, when the Western European Union was designated as the defense component of the EU by the Maastricht Treaty, which came into force in 1993, the intention was for the organization to serve as a bridge between the EU and NATO. Because membership in the WEU was restricted to EU member states only, opportunities for states to achieve "associate membership" and "associate partnership" in the EU were introduced in order to involve non-EU members in this emerging framework in an attempt to forge the WEU into a more inclusive and relevant organization."

From the Paper "Asynchronous Transfer Mode is a digital technique for high speed switching. The unit of multiplexing and switching is a cell which comprises a short fixed length information packet with a fixed length header to carry signalling information. By offering access at the cell level, information from many sources with widely differing activity patterns and transmission rates can be interleaved on a single transmission link or switched through an ATM node. As in other packet switching environments capacity is used only when it is needed."
Abstract This essay is a discussion of the reasons the Cold War began. The author describes the intentions of Stalin, Churchill, Roosevelt, and Truman and discusses whether the Cold War actually began over Europe or Asia.
From the Paper:
"Throughout the Big Three negotiations during World War II, Franklin Roosevelt was determined to work with the Soviet Union. In order to guarantee Soviet adherence to the principle of unconditional surrender and to secure their participation in the war in the Pacific, Roosevelt, often against Churchill's wishes, worked to accommodate Stalin's desire for security. Hoping to establish a postwar order in which both the US and USSR would not feel threatened, Roosevelt agreed to a buffer zone of friendly states around the Soviet Union."
Abstract The paper deals with a very detailed investigation into how the kinetics of a reaction changes from alterationss in pH, the concerntration of reactants and the addition of a catlyst in a homogenous solution. Also included is the most effective, yet efficient manner, of determining the rate of the reaction including detailed mathematical calculations. There is a lot of experimental data as evidence included and a detailed practical guide of how the investigation was undertaken and numerous discussions.This paper is essential as a reference for those studying reaction kinetics.
From the Paper "Investigate the kinetics of the above reaction and thus attempt to find a rate equation for the reaction and also establishing the best method to determine the rate of the reaction. I will do this by varying the concentrations of Iodide ions, H+ ions and Hydrogen Peroxide to generate the rate equation, I will also try to find the effect of a catalyst: Molybdate ion on the rate of reaction and also if the amount of catalyst is relevant in a homogenous reaction. The rate will be found using the iodine clock reaction and also by the use of a pH meter and a colorimeter, and these methods will be assessed to help determine the best method of analysis."

Food sources of phosphorous and calcium. Low calcium levels and osteoporosis. Postmenopausal, Senile and Juvenile osteoporosis. Hormone deficiencies. Treatment of osteoporosis; effective factors.
From the Paper "Calcium and phosphate metabolism, and bone disease
Calcium is responsible for several bodily functions which include muscle contraction, nerve impulse conduction, blood clotting, cellular communications, skin differentiation, and the functioning of many enzymes (Altruis Biomedical Network, 2001; Berkow, Beers and Fletcher, 1997). Calcium is found mainly in the bones, but some is also present in cells and in the bloodstream. The amount of calcium present in cells and in the blood is controlled very precisely by two hormones: calcitonin and parathyroid hormone. Cacitonin is produced by cells in the thyroid and parathyroid glands and the thymus. It lowers blood calcium levels by promoting the uptake of calcium by bone. Parathyroid hormone is produced by the parathyroid glands, four small glands located on the thyroid glands in the neck."
Abstract In "The American Occupation of Japan: The Origins of the Cold War in Asia", Michael Schaller discusses how American foreign policy toward Japan prioritized that country's position in the Cold War. The overall objective of American foreign policy makers was to use Japan as a buffer against communism in Asia.
Abstract This essay examines how advertising exploits women for the sake of selling products. There are certain stereotypical portrayals of women in advertisements. These are designed to sell products as well as to send certain values to the culture. In many respects, this is about how capitalism, which is the buffer to the advertising industry, needs to define and control the desires of its consumers.
Abstract This essay will seek to define how advertising in Western society exploits women for the sake of selling products. The objective is to demonstrate how print advertisements make this phenomenon transparently clear. There are certain stereotypical portrayals of women in advertisements. These are designed to sell products as well as to send certain values to the culture. The paper will argue that capitalism, which is the buffer to the advertising industry, needs to define and control the desires of its consumers. Thus, the focus will be on how certain cultural values, on which capitalism is built, need to be taught to the consumers of the society. Advertisers, therefore, need to shape as well as attract the tastes of consumers. Advertisements that include women, in other words, reinforce and justify the cultural values of female subservience -- a subservience that capitalism demands.
Abstract The paper argues that Shakespeare's heroines were vital and constructive protagonists; they were fully realized, independent, and capable beings. Through the presentation of such examples of females within the framework of the comic, Shakespeare was able to argue for a re-evaluation of gender norms and stereotypes at a safe distance. The writer explains that the comic framework served as a type of buffer, allowing him to castigate his society without coming under attack for doing so because, in the end, he was writing comedy.
From the Paper "Shakespeare's comedies, possibly due to the unfailing tendency to unfairly contrast them to his tragedies and historical dramas, have never received the critical attention they deserve. His body of comedies, according to Milton Crane, contain some of Shakespeare's most insightful comments regarding human nature and society in addition to some of his most quotable and profound lines (68-69). Nevertheless, and in comparison to the attention given the other Shakespearian works/genres, his comedies have received comparatively scant attention. While Crane forwards explanatory theories, two in particular stand out. According to the first theory, Shakespeare's comedies are underappreciated because they do not subscribe to any set ad established definition of comedy. They rarely elicit laughter and, as Crane contends, are "sensible and serious" even as they are lighthearted (68). What this means is that according to the predominant critical view, as explained by Crane, critics have been unable to truly accept Shakespeare's comedies as comedies because they are not the thoroughly humorous, farcical or satirical works that they tend to categorize comedies as being. Instead, they are, at one and the same time, lighthearted and sensible and, tragic and comic, thereby defying any categorization (68). Consequently, the failure of Shakespearian comedies to fit neatly into predefined conceptions of comedy have enforced their comparison to his other works, with the result being that his comedies end up being dismissed as lightweights within the totality of his works (68-69). It is because of this that Shakespeare's comedies have not received the attention awarded to his other works."
