Abstract
The paper explains that buffer solutions are solutions that resist a change in pH when a small amount of a strong acid or base is present. The paper looks at acidic and alkaline buffer solutions and shows how buffer solutions act according to LaChatelier's principle of equilibrium and stress. The paper explains the role of buffer solutions in our blood and also shows how the existence of buffer solutions affects how our bodies can withstand the stresses of mundane processes, such as metabolism and physical exertion, or deprivation of physiological necessities, such as water, food or oxygen.
From the Paper
"It is important that the homeostatic condition in our bodies is maintained; a balance between components of acidic and basic compositions must exist to avoid any detrimental effects on bodily functions. This balance reflects in the pH of bodily components, such as in blood. Normally, blood has a pH of 7.4; any change in blood pH by as little as 1 pH can result to coma and multi-organ dysfunction (Minnesota State University sec. 4). Metabolic processes can result in pH changes, while bodily stresses such as being in a hypoxic condition, being engaged in physical exertion, or starvation can also result in pH alterations. Proteins and genetic materials in the body can denature when they are forced to exist in extreme pH environments. However, the presence of buffer solutions ensures that drastic changes and consequent catastrophic effects will be avoided."

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 paper explains the hypotheses of this project, which are: (1) Little can be done to impact a solution's floppy disk speed, (2) SCSI disks no longer affect performance, and (3) much can be done to affect a system's 10th-percentile instruction rate. The author reports, running "Sackbut" on commodity operating systems, such as LeOS and Minix, the experiments proved that exo-kernelizing the saturated online algorithms was more effective than monitoring them. This paper concludes that the author's system sets a precedent for the visualization of robots, and it is expected that cryptographers will improve on Sackbut for years to come. Tables.

From the Paper
"Contrarily, this solution is fraught with difficulty, largely due to digital-to-analog converters. Predictably, Sackbut constructs fiber-optic cables. Existing constant-time and classical heuristics use extensible technology to develop the intuitive unification of the partition table and the Turing machine. We view steganography as following a cycle of four phases: synthesis, construction, storage, and emulation. Such a hypothesis is entirely an unfortunate mission but has ample historical precedence. The basic tenet of this solution is the important unification of linked lists and A* search. Combined with the Ethernet, such a claim constructs an analysis of the transistor."

"Does Selective Attention (mechanism that further processes information in a prespeech memory buffer) inhibit the processing of unattended information or is there a cognitive mechanism that automatically processes input even if humans are not attending to it? The research attempts to answer this question through an exploration of the effects of auditory color-word interference on a visual Stroop interference task with a spoken response.
The context within which the conducted research can best be understood begins with some early work in the field conducted ... In this early work where subjects monitored (selectively attended to) input, Broadbent found that (1) ... "

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.

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
"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 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
"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
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."
