Paper Abstract: Technical discussion of toxic properties of various weapons. Purpose of producing physiological or physical effects on enemy forces. Modern origin in use of mustard gas in World War I. Describes blistering agents (vesicants), nerve gas, VX, Soman, B2, toxins and allergens. Treaties to prevent use of chemical weapons. The Geneva Protocol of 1925 and the Chemical Weapons Convention of 1993. Paper Introduction: Chemical weapons use the toxic properties of chemicals to produce physical or physiological effects, usually on enemy forces during wars (FAS-Introduction, 2001). Although they have been used throughout history, chemical weapons are thought of as originating during World War I with the use of mustard gas by both sides. In 1925, the Geneva Protocol was signed which prohibited the use of chemical weapons in warfare, but several nations who signed the pact, including the United States, did so with the proviso that they reserved the right to retaliate in kind if chemical weapons were used against them. Neither side used chemical weapons during World War II. Common agents in use are: the blood agents arsine, cyanogen chloride and hydrogen chloride; the choking agents chlorine, diphosgene, PFIB and phosgene; nerve agents GA (tabun), GB (sarin), GD (soman), GE, GF, V Read the Entire Essay.

Paper Introduction: CONSIDERING A MARKET FOR HUMAN ORGANS: A SUPPORTIVE POSITION ASSESSMENT In the United States, a country that regularly condemns human rights abuses, including trafficking in human organs, in other countries, amoral economists, politically conservative organizations that regularly condemn fetal cell research, and others who view “the market” as God (with a Capital G), promote the concept of a free market in human organs. The usual justification for this concept is that the non-market regulation of the collection and assignment of human body parts for transplant operations is a failure because it allows the development of an imbalance between the supply and the demand for human organs (Schiller 1). According to the proponents of a free market in human body p Read the Entire Essay. If this paper is not what you are looking for, you can search again: or We can write a Custom Essay for you. | ||

Paper Abstract: Discusses the notion of scientific discovery. Testing to ascertain whether a hypothesis is true or false. Examines the views of Thomas Kuhn and the "paradigm." Karl Popper's contention that deductive testing is true science and induction is false science. Rejection of Popper's and Kuhn's ideas by Imre Lakatos and Paul Feyerabend. Paper Introduction: True Science vs. Pseudo-Science Introduction and Purpose True science and pseudo-science, it has been argued, can be distinguished from one another by an examination of the nature of scientific discovery, with particular attention to the use of a rigorous methodology or test that allows one to ascertain whether a hypothesis is true or false. This brief essay will analyze this notion in light of the views of Kuhn, Popper, Lakatos, and Feyerabend and determine which of these views is most convincing. First, a systematic reconstruction of the basic ideas presented by Thomas Kuhn will be presented. Kuhn and the Paradigm Shift Thomas Kuhn (1996) describes a “paradigm” as an example of accepted scientific practice, including law, theory, application and instrumentati Read the Entire Essay.

Direct and indirect physical evidence. Implications for understanding long-term survival of Earth. Based on a 2002 article in the "Scientific American." Paper Introduction: The article under review is titled “Repeated Blows: Did Extraterrestrial Collisions Capable of Causing Widespread Extinctions Pound the Earth Not Once, But Twice—Or Even Several Times.” It was published in the March 2002 issue of the Scientific American. In this article, Becker described and discussed the validity of the recent research efforts to determine whether the collisions between gigantic asteroid rocks and the Earth could have triggered dramatic biological crises that transformed the planet and led to the extinction of living species. Essentially, this article focuses on how researchers have sought to find physical evidence to prove that asteroid impacts caused the great catastrophes including the extinction of the dinosaurs 65 million years ago and the Great Dying in which 90 percent of the planet’s species became extinct appro Read the Entire Essay.

Paper Introduction: The Scientific Revolution Generally, scholars date the beginning of the Scientific Revolution at the 1543 publication of Nicolas Copernicus’s “De Revolutionibus Orbium Coelestium,” in which he challenged the Ptolemiac universe and argued instead that the sun was the center of our solar system (Hooker). Over roughly the next 100 years, European scientists and philosophers would publish numerous texts that significantly altered, and today we say updated, understanding and knowledge in astronomy, biology, chemistry, human anatomy, mathematics, optics, philosophy, physics and zoology (Hooker). The foundations for these scientific advancements, however, came from Arabic translations of ancient Greek texts as well as other Islamic and Chinese Read the Entire Essay.

Modifications within a species. Darwin's empirical observations and findings in the ORIGIN OF SPECIES. Critical views of Darwin's methodology by his contemporaries. Impact of Darwin's scientific contributions to modern thought. Paper Introduction: Charles Darwin roamed the earth by land and by sea during a time in which preeminent and pervasive religious and scientific dogma defended a similar principle: that Creation by one supreme deity accounted for all life on this planet. From this, a hallowed belief in the fixity of the species followed logically and irrevocably. No surprise then, that Darwin’s hypothesis of natural selection was met by such staunch resistance from such a broad swathe of detractors. His arguments, though logically deduced from a catalog of exhaustive research, were viewed as unscientific, and therefore inconclusive. Utilizing natural selection as the principle mechanism which drives the evolution of all species, Darwin was challenging more than scientific methodology, however. His contr Read the Entire Essay.

Neurochemistry research. Paper Introduction: The March 16, 2002 issue of The Economist makes reference to the infamous thinking computer “HAL” that was introduced in 1969 in the Stanley Kubrik film “2001: A Space Odyssey”. It declares: “2001 has come and gone, and there is still no sign of a HAL-like computer”(AI 68). And this is true. The Artificial Intelligence products of today seem at times to have fallen a bit short of the HAL/AI prototype imagined by Kubrik in 1969, and at times AI seems to have developed quite a bit more radically than expected. Robots produced by world-renowned electronics and automotive makers such as Sony and Honda have wowed the public not so much with the abilities of the robots they have produced as with the four to five-figure pricetags that are customarily attached to them.

Paper Abstract: His contributions to the field of chemistry. His original work in thermodynamics and valence theory. His academic background and career as a faculty member at MIT and U.C. Berkeley. His scientific research and theories of electrons bonding in pairs and the role of isotopes in chemistry and physics. Paper Introduction: Scientist Gilbert Newton Lewis' reputation lies in his extensive contributions to the field of chemistry. Lewis was born in Weymouth, Massachusetts on October 23, 1875. He was schooled at home by his parents in his early years, and at age 14, entered the University of Nebraska. After three years there, he transferred to Harvard College. After receiving his baccalaureate degree at Harvard, he taught for a year at Phillips Andover Academy before returning to Harvard to study for his doctorate (Harris, 1999). Lewis earned his Ph.D. at the age of 24 under the supervision of T. W. Richards, who trained him in experimental techniques and careful measurements. His thesis topic was on the thermodynamics of zinc and cadmium amalgams, at a time when physical chemistry was just beginning to be recognized as a branch of science. (Harris, 1999).

How neutotransmitters are involved in the development of emotional disorders. Cites studies on how exercise contributes to physiological and psychological well-being. The role of exercise in helping indivuals regain control over their emotions. Paper Introduction: Stress, anxiety, and depression tend to be interactive and are often viewed as negative characteristics of human behavior. Though these emotions and responses have developed as a protective mechanism and originate from needed evolutionary characteristics, they tend to get out of control and work to create conditions, which move the individual away from homeostasis. The brain is made up of cellular connections mediated by chemical messengers called neurotransmitters. These same neurotransmitters are involved in the development of depression, stress and anxiety related disorders in otherwise healthy individuals. Returning these individuals to a state of chemical and emotional equilibrium can be achieved through the introduction of their respective medications and as recent studi Read the Entire Essay.

Darwin's evidence & observations & theory of common descent. Religious & secular beliefs of Darwin's time. Paper Introduction: When Darwin published his book, Origin of Species, he sparked off a huge debate between the authority of science and that of religion. The debate continues even today. This paper will look at Darwin=s theory of cause and change, and the corresponding religious viewpoint. According to the philosophy of natural theology widely accepted in England in Darwin=s time, God had designed, and looked after, every species and its numerous adaptations (Mayr, 1991, p. 14). Darwin could not accept this explanation of the enormous diversity and adaption he observed. His own observations were also in conflict with the belief of the theologians in a perfect world. He questioned why all the species from former periods were extinct if they were perfect. To Darwin, creation as described in the bible was contradicted by al Read the Entire Essay.

Paper Abstract: Examaines how fact & theory interact in Darwin's writings on coral reef formation. Paper Introduction: Coral reefs are composed of a myriad of individual coral polyps which are living creatures encased in calcaceous shells, and reefs cover approximately one percent of the earth=s surface (http://www.library.thinkquest.org/25713/corals.html). They are the world=s second most productive ecosystem behind rain forests. As they develop, coral reefs characteristically sink into the water, and the reef goes from being a fringing reef to being a barrier reef, to becoming an atoll. This paper will look at how fact and theory interact in Darwin=s discussions and writings on coral reefs.

Paper Abstract: Examines the social & economic impact of 3 recent major storms: Hurricane Andrew (1992), Hurricane Opal (1995), & Hurricane Marilyn (1995). Paper Introduction: Each year, portions of the United States are battered by the high winds and rains of hurricanes. These storms can cause massive damage depending on the speed of the winds and the precise areas of land where the storms come ashore. These storms are carefully tacked by various scientific and governmental entities which measure the speed of the wind, the direction of the storm, and the course of the devastation wrought by them. During the hurricane season, there are likely to be a succession of such storms which fortunately do not usually assault the same locales and which may also miss the land altogether or dissipate before reaching land. An analysis of three recent storms will show the sort of devastation they can bring. Probably the major storm of 1992 was Hurricane Andrew, which left behind considerable devastation in Florida and other regions so th Read the Entire Essay.

Science and its "logic" is often presented as the ultimate arbiter of truth and value. However there are perspectives quite critical of this "immaculate conception" of science and the scientific method. The analysis which follows will focus on the insights of Paul K.

Paper Abstract: Discusses some of the ethical concerns raised by the advances in cloning during 1997. Focuses on the possibilities of human cloning. Paper Introduction: Cloning has been much on the news of late with the announcement of the cloning first of sheep and then of cattle and even a monkey. The latter event in particular has made people more concerned about the possibility of human cloning. Medical experimentation on human beings is often a necessary component in medical discovery and progress, and the medical establishment recognizes this fact as well as the many dangers that come with such experimentation. As a result, the profession has developed stringent and specific regulations and requirements for allowing such testing, including the requirement for informed consent by the subjects of such experiments. Human experiments have been conducted without such consent and without other safeguards to protect either the subjects of the research or the integrity of the research itself, which only undercuts the ability of the profe Read the Entire Essay.

Paper Abstract: Discusses the rise of new scientific ideas in the 16th, 17th, & 18th centuries. Compares the Thomistic theories that preceded that era with the theories of Descartes, Newton, Locke, & Rousseau. Paper Introduction: The new scientific ideas of the 16th, 17th, and 18th centuries challenged the prevailing assumptions of the Aristotelian/Christian paradigm. Thomas Kuhn states that competing paradigms are "incommensurable," meaning they lack a common base for comparison. A paradigm in this sense is a shared set of understandings. Kuhn is attempting to explain the value, meaning, and nature of what he calls normal science, meaning research that is firmly based upon one or more past scientific achievements, or the achievements that some particular scientific community accepts for a time and that supplies the foundation for that community. Paradigms are achievements sharing two characteristics Kuhn identifies as essential: 1) their achievement was sufficiently unprecedented to attract an enduring group of adherents away from competing modes of scientific activ Read the Entire Essay.

Paper Abstract: Examines the health care reform debate of 1993-94. Discusses various strategies to change public attitudes, including the social change, rational-empirical, & power-coercive models. Paper Introduction: Background Americans believe they are facing a crisis in health care marked by rising costs for providing health care along with an increase in the number of people who are either uninsured or under-insured. This problem has long been ignored by policymakers, but recently President Clinton has put the issue in the forefront of political debate and has spurred a flurry of suggestions. The administration has put forward a health care plan, and the Republicans have responded with a health care initiative of their own. The problem itself has been well documented. In the last 15 years, the number of uninsured Americans has grown, and most estimates in 1991 place the number lacking public or private coverage at between 31 and 36 million.

Paper Abstract: Describes the types of stones that are categorized under the geological heading of corundum. The stones discussed are the ruby and the sapphire. Paper Introduction: The ruby is one of the two stones categorized under the heading of corundum-- sapphire is the other. Ruby and sapphire may appear to be quite different but are in fact color varieties of the same mineral, chemically and physically the same, differing only in the amount of impurities they contain. It is in fact the chemical impurities that give them their value, for pure corundum is colorless. Corundum is a relatively abundant mineral. It is surpassed only by diamonds in hardness, so tons are mined each year to be used as an abrasive. The hardness contributes as well to the value of the gems consisting of this mineral. Corundum is composed of two light elements, aluminum and oxygen, and the close packing of these elements along with the strong bonding of the atoms are what give the gems their hardness and specific gravity.

Paper Abstract: Technical examination of methods of reduction, history, phase diagrams, density, hardening, more. Paper Introduction: METHODS OF REDUCING POROSITY IN BRASS Introduction. Brass is an alloy of copper and zinc. It has been said that the measurable density of any pure metal(s), whose density(ies) are well-known, will always be less than their analytically computable densities--or their "true" densities (7:196). Why? A lack of maximal density, or some porosity, must exist in the metals' lattice structure or must be introduced in the alloying process. Explored here are methods metallurgists may use to minimize porosity in brass. Brass. A useful alloy of two metals, copper and zinc (9:166), brass has been formed for cultural uses and ornamentation since the 13th century BC (1:9).

Paper Abstract: Examines history of discoveries & inventions related to electricity & its practical applications, from 16th Cent. to nuclear energy, fiber optics & superconductors. Paper Introduction: Electricity is such an integral part of daily living that it is difficult to imagine a time when it did not "exist" a time when there were no lights, no computers, no phones, and no appliances. A time when everyday tasks like laundry, cooking, and vacuuming were not made easy with mechanics run by electricity. However, such a time did exist. But with the observations and experiments of curious and intelligent scientific figures, electricity was discovered and harnessed. Awareness of electricity dates back to the Greeks who discovered that amber, when rubbed, attracted lightweight particles such as straw (Dunsheath, p. 1). However, the value of this force was not determined until much later when scientists began to study it in more depth and invent equipment that could measure and capture it. Read the Entire Essay.

Paper Abstract: Analyzes negative & positive portrayals of scientists & their preoccupations in "Contact," "Pi," "Jurassic Park," "Absent-Minded Professor," "Insignificance,' more. Paper Introduction: The depiction of science and scientists in films and other popular media has long been characterized either by fear and anxiety at scientists' potential power or by wild acclaim for their accomplishments. In both cases, however, the popular reaction is based largely on incomprehension. There are variations on the basic stereotypes of the mad and the benignly inspired scientist, however, and filmmakers tend to express general societal concerns in their choice of type. In addition, filmed representations of scientists tend to repeat or reinforce popular misconceptions about the nature of their work and goals. Thus the choice of any of the mad, evil, kindly, distracted, driven, and inspired characters who populate films about scientists often depends on what, in general, people believe scientists hope to do.

Paper Abstract: Examines arguments attempting to support or discount theory of the origins of universe. Paper Introduction: BACKGROUND The Big Bang Theory is an explanation for the beginning of the universe. The universe today is expanding, as can be seen in the way all matter is moving outward. Tracing this movement back through time takes all matter to a single point, leading to the view that at one time all matter was concentrated in a singularity which for some unknown reason exploded, throwing all material now seen in the universe outward from that central point. There are various corollaries to this theory, such as the issue of whether the expanding universe will continue to expand forever or will eventually reach an end point and fall back on itself. There are also various consequences of the Big Bang which can be used to determine if the theory has validity. A number of researchers have examined aspects of the Big Bang theory and developed ideas r Read the Entire Essay.

Paper Abstract: Examines nature & functions of proteins & special intake requirements of male & female athletes for exercise activities, effects of deficiency. Paper Introduction: Proteins perform a wide variety of important functions in humans (Devlin, 1997, p. 24). These functions can be grouped into dynamic and structural. Dynamic functions include transport, metabolic control, contraction, and catalysis of chemical transformations. In their structural functions, proteins provide the matrix for bone and connective tissue, giving structure and form to the human organism. An athlete who is building muscle mass can have twice the protein intake requirement of the average person (Dolby, 1998). With American athletes, it is rare to find a protein lack since the average American already consumes two to three times the daily requirement for protein. This paper will look at the protein intake requirement of athletes, both male and female, for various types of exercise activities. Read the Entire Essay.

Paper Abstract: Definition, general principles, apparatus used, sampling, types, conductivity detectors. Paper Introduction: Gas chromatography is a method for the separation and analysis of complex mixtures of volatile organic and inorganic compounds (1:666). Most compounds with boiling points less than 250oC (480oF) can be analyzed using this technique. This paper will describe the apparatus used for gas chromatography, the principles on which it works, how a thermal conductivity detector works in gas chromatography, and whether or not it can be used with a sample of potassium t-butoxide. General Principles of Gas Chromatography There are two types of gas chromatography: gas-liquid chromatography, where the sorbent is a nonvolatile liquid called the stationary liquid phase, coated as a thin layer on an inert, granular solid support; and gas-solid chromatography, where the sorbent is a granular solid of large surface area (1:666).
