Abstract
This paper reports on experiments addressing the issue of developing synthetic analogs of erythropoietin, a protein hormone produced by the kidney that stimulates the production of red blood cells. The hormone is given to patients suffering from kidney failure when they develop anemia, which occurs primarily because their production of erythropoietin is abnormally low. The company has produced an analog that stimulates red blood cell production and so mimics the action of erythropoietin. The analog has been derived from bone marrow cells in culture. The product may be called Redgen. The current research is a test on Redgen to characterize its activity and signaling pathway.

Abstract
This paper explains that synthetic diamonds have the same unique qualities as natural diamonds, hardness, density, superlative strength, and thermal conductivity. The author points out that synthetic diamonds are created in a laboratory, avoiding the high costs of mining, transportation, foreign taxes, and tariff issues. The paper relates that the future of synthetic diamonds is limitless, especially their use as radiation sensors, light emitters, and unwettable coatings.
From the Paper
"In addition to the time saved, there is also a cost issue. Natural diamonds are produced in a limited number of countries, including Australia, Botswana, Russia, and Congo Republic. There is only one mine found in the United States. Since Americans are the consumers of over 50 percent of the world?s diamonds, this produces a costly problem. The costs of mining in foreign countries are high. According to De Beers mine, a leading producer of natural diamonds in South America, 250 tons of ore would need to be excavated to find one stone that would be large enough to equal a one-carat diamond."

Abstract
The following is an essay and analysis on W.V. Quine's central arguments in his work titled "Two Dogmas of Empiricism". In particular, this paper will focus on the argument that maintains that there can be no analytic truths with out some consideration of synthetic variables as well. In short, it is argued that synthetic factors have a determining impact in shaping what we have traditionally regarded as 'analytic'. Thus, a consideration and analysis of what Quine regards as 'analytic' and 'synthetic' becomes a central concern.

Abstract
This paper examines the development of the use of synthetic diamonds as gemstones, rather than primarily for industrial purposes. The paper approaches this issue from several angles. These include the current nature of the market and the demand for synthetics, the chemical vapor deposition (CVD) manufacturing process and the differences between these and natural diamonds.
From the Paper
"Synthetic diamonds, according to some, represent the future of the diamond industry, if not in whole then at least in part. The demand for diamonds combined with rising costs has caused manufacturers and consumers to look for other options to meet their fine gemstone needs. Simply put, there are only so many natural diamonds to go around. As a material, diamonds take an exceedingly long time for nature's pressures to create. Synthetic diamonds offer the possibility of diamond production on demand, rather than an industry that is subject entirely to the whims of mining and the possibility of unearthing new stores of this finite limited resource. Demand for diamonds in general is up, even though supplies of the gem have dropped significantly. The result is excellent market conditions for the viable emergence of a synthetic diamond industry."

Synthetic A Priori Knowledge, 2002.
An analysis of Kant?s theory of synthetic a priori knowledge and a comparison of Kant's beliefs to Hume?s beliefs.

Abstract
This paper discusses and compares analytic and synthetic judgement. The writer describes Kant's belief that all knowledge begins with experience, and that both experience and knowledge combine to give the reasons for why things happen. The paper draws comparisons between this idea and that of Hume, relating Hume's belief that events have explanations as to why they happen, an action brings a reaction.
From the Paper
"Kant states how the reading of David Hume changes his thoughts and how it directed his investigations in the field of speculative philosophy. Kant wanted a ?Copernican Revolution? in the response to Hume. ?A recognition that the appearance of the external world depends in some measure upon the position and movement of its observers? is a response called ?Copernican Revolution? (Kemerling 1). Kant wanted to move beyond the rationalist but he did not agree with the empiricists either."

Analytical and Synthetic Cubism, 2004.
A discussion on the terms analytical Cubism and synthetic Cubism with reference to the work of Pablo Picasso and Georges Braque.
2,117 words (approx. 8.5 pages), 8 sources, MLA, £ 46.95
»
Click here to show/hide summary
Abstract
This paper explains that Cubism is the process of passage from a bar-baric dis-symmetry to an advanced abstract geometry. The paper then looks at how the the term analytical Cubism refers to Picasso and Braque's work of 1910 through early 1912 and how the term synthetic Cubism refers to their work of later 1912 through 1914. It also examines the objective contributions of Picasso and Braque to the development of modern art, particularly towards abstraction.
From the Paper
"By 1909, Picasso, working in close collaboration with Georges Braque, had invented Cubism, a kind of painting more sculptural than any before, since it presented simultaneously more than one view of the subject. Indeed, Picasso had definitely renounced the traditional chia roscuro - the technique of evoking three-dimensional form by reproducing the way that incident light plays across it, producing a sequence of highlights and shadows. Picasso apparently considered chiaroscuro a "dishonest" way of representing three-dimensional form; he therefore turned to faceting as a means of describing three-dimensional form without using conventional shading. After the dematerialization of form in Impressionism, and the flattening of form in Post-Impres sionism, this restoration of a sense of sculptural solidity (without a return to conventional real ism) was a major achievement.

"The Way to Produce Synthetic Cocaine
Introduction: History
Relative to medical usage, a stimulant is defined to be an agent that arouses organic activity, strengthens the action of the heart, increases vitality, and promotes a sense of well being. Cocaine is one of the most powerful stimulants found in nature (Future of drug use, 1997).
Cocaine was organically derived from the coca plant found throughout South America. The first use of the coca plant for its stimulant properties can be traced to the ancient Incas in Peru. Called the "divine plant," Inca nobility and priests chewed the leaves of the coca plant in order to achieve a trance state of consciousness during religious ceremonies. Later, common people began to chew the leaves in order to reduce fatigue..."

Synthetic Methods for Enantiomers of Drugs, 2002.
An analysis of the various methods of producing pure enatiomeric drugs.

Abstract
This paper discusses how ever since the ?Thalidomide? incidence last century there has been an ever-increasing amount of resources injected into optical isomeric research and in attaining pure enantiomeric products. It shows how due to different stereochemical characteristics, different isomers will have different interactions with biological receptors in the body, giving rise to different actions. A resultant undesirable effect is therefore inherently possible upon the consumption of chiral drugs, for that reason it is imperative that the end drug mixture is as entiomerically pure as possible. It describes the 3 basic methodologies for single enantiomers: chirality pool, kinetic resolution and asymmetric synthesis and examines the basis of and the techniques of separating them.
From the Paper
"One way of the use of chirality pool molecules merely requires the maintenance of pre-existing chirality throughout a synthesis, with transformation of other parts of the molecule by formation of new chemical bonds or inter-conversion of functional groups. Otherwise, utilising chirality pool can afford a so-called ?control element? for the creation of new stereogenic centres by ?substrate-directable? reactions. Such reactions may involve complete transfer of chirality from one region to another intra-molecularly.[1]"

Abstract
This paper describes Plato's presentation of the kind knowledge that is necessary for a philosopher king. This paper states that the Cave Analogy is used to compare the effect and the lack of knowledge on human nature and the responsibility, which accompanies education. The author feels that there is a distinct parallel between Plato?s Cave Analogy and the modern world particularly the many individuals who live in poverty and ignorance and the subjugation of women in certain countries.
From the Paper
"Plato describes the cave as an underground dwelling with an entrance up at a distance. The men that live there are chained. They can only see in front of them. (They represent the uneducated). A fire that provides them light, but it is above and behind them. Between the light and them is a path that has a low wall alongside it. Men carry all sorts of things along the wall. But, the chained men only see the shadows casted by the fire and believe the shadows to be the real objects. (This is the world of shadows)."

Abstract
This paper discusses nucleoside analogues as used in chemotherapy and antiviral therapy. The different types of nucleotide analogues are outlined by structure. The transportation of these drugs across the lipid membrane, intracellular metabolism (activation) and mechanism of action are also discussed. The last portion discusses anti-retro viral and chemotherapeutic uses of some agents as outlined above, resistance and counter-resistance factors.
From the Paper
"Structure and different groups of nucleoside analogues. Nucleoside analogues are synthetic drugs that mimic certain nucleosides found intracellularly, specifically the cell nucleus and mitochondria. These drugs are mostly used in oncologic therapy as well as antiviral therapy. Their general mechanism of action relies on their ability to insinuate themselves into replicating strands of DNA or transcribed RNA, taking the place of the nucleoside they are derived from. This has the effect of halting DNA or RNA synthesis, halting viral replication and in some cases, triggering apoptosis. In either case, this consequently results in slowing down and stopping tumor cell or viral replication."

Abstract
This paper examines the positive benefits to be derived from a phone company switching from analog technology to digital technology - especially in its central offices. The paper reviews the financial gains to be made as well as the customer service benefits and suggests that companies not already on the digital bandwagon had best do so in the near future.
From the Paper
"The benefits of digital telephone technology versus analog telephone technology are not necessarily obvious, but they are present and they deserve exposition. The following paper will examine the benefits that would accrue to a telephone company if it were to switch from analog technology in its central offices to digital technology. More specifically, the paper will examine the financial benefits and the customer service benefits to be derived insofar as benefits in these areas are benefits that will most impact the future success and prosperity of any telephone company. Among other things, the following paper will look closely at the technological innovations of the new digital technology. "

Abstract
This paper reviews a lab report on three experiments testing a new product called Redgen, meant to mirror the action of erythropoietin, a protein made by the kidney to stimulate the production of red blood cells. The paper discusses how having developed Redgen, the company now has to test it and to demonstrate that it is analogous to erythropoietin and provides similar benefits to the patient. To demonstrate this, the paper reviews three experiments that have been conducted to show the different aspects of the product and ways in which Redgen acts as effectively as erythropoietin.
From the Paper
"To develop a synthetic analog for erythropoietin, a protein made by the kidney to stimulate the production of red blood cells. Use: The hormone serves in the treatment of kidney failure, for some patients develop anemia when their production of erythropoietin diminishes. Treatment: To allow for treating this condition, the company has developed a product called Redgen to achieve the same benefits as erythropoietin by imitating the action of that hormone. Redgen is acquired from bone marrow cells in culture. "

Abstract
"This paper examines the legal issues surrounding the use of the additive MTBE, methyl tertiary butyl ether, a synthetic chemical mandated for use as a gasoline oxygenate. The additive has the effect of reducing carbon monoxide emissions by assuring more complete fuel combustion. The additive is used because of growing public concern over air quality. However, the fact that MTBE is effective in reducing automobile emissions has been overshadowed by the fact that the substance is now found more frequently in groundwater and surface waters across the United States. "
From the Paper
Methyl tertiary butyl ether (MTBE) is a synthetic chemical mandated for use as a gasoline oxygenate. The additive has the effect of reducing carbon monoxide emissions by assuring more complete fuel combustion. The additive is used because of growing public concern over air quality. However, the fact that MTBE is effective in reducing automobile emissions has been overshadowed by the fact that the substance is now found more frequently in groundwater and surface waters across the United States. Because of this unintended consequence, and because of the health hazards posed by the MTBE itself, regulators became more concerned about the environmental impact of MTBEs. Such an impact occurs for several reasons: M MTBE tends to degrade very slowly. M Due to the dipole nature of its ether bond, it is highly soluble in water. M It does not easily absorb onto the aquifer matrix. M Retardation of MTBE is therefore minimal.
