Abstract
This paper discusses quantum tunneling, which is a function of quantum-mechanical activity in the instance where a particle moves against potential energy and appears on the other side of the energy barrier. The paper describes the theory behind quantum tunneling. It focuses on the Esaki diode and looks at its potential uses now and in the future.
From the Paper
"While the Esaki diode has not been widely used, its application is nearing widespread use in computers. The diode circuits have been developed and crash programs have been implemented by major computer makers in order to apply it to communications equipment. Yet there still is resistance to the use of these phenomenal little circuits, where currents may be reversed. Some designers and engineers prefer transistors. Proven circuits and solid-state technology that is already acceptable seem to be sufficient, they say. But interest in the diode is so great that they are being forced to try to apply this not-so-new technology to obtain ultra-high speed and ultra-low power consumption in the computer industry. The diode phenomenon dominated 1960 Physics Conferences."

Abstract
This paper discusses the development of quantum mechanics, illustrating its background which began with the classical theory of the atom, continued to Bohr's simple atomic theory, and was developed further with de Broglie's wave theory, Heisenberg's uncertainty principle and Schrodinger's equation. To further investigate the development of quantum mechanics, each of these stages are looked at in more detail, showing the main ideas that each stage added to the understanding of the atom. This paper shows that quantum mechanics is based on the combination of the ideas of many scientists, with the final acceptance of quantum theory occurring when Schrodinger's equation tied together previous theories and allowed them to be applied to subatomic particles.
From the Paper
"The classical theory of the atom is based on the model of an atom being made up of a positive nucleus containing protons and neutrons with negatively charged electrons orbiting around this nucleus. This model was first proposed by Rutherford in 1911 who described the atom saying, "Most of the volume of the atom is empty space in which electrons move around the nucleus." This basic model of the atom has been expanded on and used to determine how chemicals react with each other, the charges of chemicals and the physical properties of chemicals. While this has involved expanding the theory, the basic understanding of the structure remains the same."

Abstract
This paper examines how quantum cryptography is a fast growing form of encryption that is not based upon the difficulty of mathematical algorithms and instead employs quantum physics to encrypt information on the physical level. It emphasizes the need for an innovative cipher as well as the need to inform the IT community regarding the commercial application of quantum cryptography. It also provides a broad overview of the quantum cryptographic protocol and operation using fiber optic media.
From the Paper
"The integrity of information between sender and receiver relies upon secure channels and more importantly the ability to protect the information from unauthorized recipients. The transmission of information can be compromised when a third party listens in on the transmission media measuring the physical object. Consequently, the eavesdropper can effectively intercept the contents of a communication. Certain types of classical cryptography have proven vulnerable to the interception of data and the incident can remain undetected during the entire transmission. This idea of a man-in-the-middle attack on communication media using quantum cryptography is not possible due to the laws of quantum mechanics. Quantum superposition's and quantum entanglement are two properties of quantum physics used to detect eavesdropping. "

From the Paper
"The fact that statistical physics can be taken as a particular type of statistical inference does not seem to play too much of a theoretical role in physics today. It is perhaps the strong suggestion of subjectivity associated with the concept of inference that determines physicists to rely mostly upon kinetic basis of statistical laws. However, recognized or not, the statistical inference has played a very important part in such fundamental problems like building physical concepts. One illustrative example is the concept of quantum. Originally related to the frequency property of light, it was in time explained as associated with its particle properties, then with the temperature of light. All these properties can be traced logically back to the particular type of statistics which is fundamental for the ensembles characterizing the black body radiation. More than this, that very type of statistics is essential in the contemporary sophisticated descriptions of the squeezed states and their related concepts. This essay presents details of the statistics involved in the history of quantum, and the essential points of this history."

Solutions to Reduce The Risk of CTS
Ergonomic Guidelines for CTS
Effects of Other Risk Factors
From the Paper
"The Occupational Safety and Health Administration organization has looked at Carpal Tunnel syndrome for many years and has developed a list of guidelines for employers to use when trying to prevent the occurrence of the syndrome in their workforce. At this time it is not mandatory to comply with the guidelines but employers who do so will find they have a reduced incidence of claims which in the long run will be extremely cost effective. In addition by implementing the guidelines set out by OSHA on a voluntary basis it will help reduce the claims thereby encouraging OSHA not to mandate but to allow voluntary participation in the guideline implementations.
The one thing that OSHA does want to mandate is what happens to a worker who has been diagnosed by a physician as having Carpal Tunnel Syndrome. "

»
Click here to show/hide summary
Abstract
This paper examines how carpal tunnel syndrome has become one of the most hotly discussed issues facing workplace technology in the 1990s and how as computers become increasingly omnipresent in offices worldwide, and as the workweek continues to become more hectic and fast-paced, requiring more labor hours, employees soon spend most of their days in front of a computer terminal. Apart from the discomfort to the employee of the syndrome, it also discusses how human resource offices should indeed be aware that carpal tunnel syndrome, can for the most part be prevented and thus avoid substantial expenses to the firm, the insurer and the employee, as well as possible legal costs.
From the Paper
"The syndrome is usually caused by excess pressure upon the median nerve caused by scarred tissue, repetitive finger motions, tendon sheath inflammation, fractured forearms, or sprain or dislocation occurring in the wrist. Although carpal tunnel syndrome may be hypothetically caused by other factors, such as obesity and pregnancy, the ailment is most often found in individuals who work at their computer terminals excessively, with long hours of typing, and thus put their hands and wrists at risk of swelling and undue pressure. Although carpal tunnel syndrome is "usually curable" (3) through surgery or self-relaxation techniques such as the taking of breaks to relieve stress, the syndrome can potentially lead to such effects as partial or complete paralysis or numbness of the affected hand and wrist.

Abstract
This paper looks at the differences between two new technologies, quantum and biological computing, examining how they can be used in different fields. It examines problems experienced in the development of these computing techniques but also shows how much of an impact they would have on current technology. The writer explains that instead of using microchips, a quantum computer uses a liquid of appropriate molecule which is more accurate.
From the Paper
"Quantum and Biological computing are two technologies which are on the forefront of advancement in computers today. Both technologies are relatively in their infancy, but so far there have been a good amount of promising results in both research and prototypical experimentation. The reason behind the quest for a different type of computing system is not simply for the purpose of advancement for the sake of advancement; but rather because conventional microchips are nearing the apex of their computation ability for certain applications. There is a lot of competition in the field of quantum computing, both for the financial gain, and scientific breakthroughs which would result in a practical quantum computer. The field of Biological computing is one which does not hold the promise of quantum computing, as far as practical application; But does open new doors into the realm of computing without being tied to digital circuits and all the limitations they possess. Conventional computers can be improved by further miniaturization of circuits, but the major roadblock is that transistors and electrical wiring can ultimately only be made as slim as the width of one atom. Once again business and science are teaming up in order to benefit each other, and bring about the next great evolution in computing technology."

Abstract
This paper discusses the philosophical and psychological themes and meaning in Ernesto Sabato's novel, "The Tunnel". The paper explains how the symbolism in the story and Sabato's narrative technique convey both the complex thoughts of the protagonist and the message of the story that man is incapable of controlling the circumstances in which he is thrown, nor can he alter his future.
From the Paper
"The story begins with Castel in prison for the murder of Maria Iribarne, the woman he loved passionately. The narrative is not complex and the author has used rather simple and direct techniques to convey the issues troubling the highly complex mind of the protagonist. Since the protagonist and his thoughts are highly complex, the author has tried his best to keep the narrative simple in order not to confuse the reader too much. The confession of the crime appears very early in the novel when the " protagonist introduces himself in these words: "It should be sufficient to say that I am Juan Pablo Castel, the painter who killed Maria Iribarne.'' (Sabato p.09)."

Abstract
This essay explains the basis of Quantum Mechanic Theory of the atom, which describes the behavior of electrons in atoms & molecules. The author examines this theory and provides a detailed analysis of it.
From the Paper
"The Quantum Mechanics Theory describes the behavior of electrons in atoms & molecules. Quantum Mechanics is also referred to as Wave Mechanics. The theory of quantum mechanics tells us that in the atom, electron waves are standing waves. This theory was devised by Max Planck in 1901. He stated that light is emitted by the atoms of a luminous body in separate packets or bundles of energy called quanta or photons. One or more of the electrons revolving about the nucleus of an atom can be made to jump from one orbit to another. As they do so one or more photons are emitted. This energy radiates from the luminous body as electromagnetic waves. The energy content of a photon determines the length and frequency of the wave. Wave mechanics views the probability of finding an electron at a given point in space."

From the Paper
"Quantum Corporation was founded in 1980 in California and since then has managed to capture a significant portion of the digital and analog storage media market. At the start of the year 2000, for example, the company already employed 6,300 employees and showed no indication that growth wasn't an inevitable part of the company's future. Quantum operated with extreme authority in the market, providing storage media for all the major PC manufacturers, not to mention storage solutions to others such as the makers of TiVo. To give some perspective, in the year 2000, Quantum managed to ship 30 million desktop drives, retained its title as the market share leader for the seventh year in a row, and captured 24% of the total market (McAfee 2)."

Abstract
The author begins the paper with an account of a panic attack he suffered. He then goes into the definition of panic disorder and the similar disorder anxiety disorder. He lists the symptoms, treatment, and general statistics of the two disorders. Paper includes pie graph with explanation of the statistics.
From the Paper
"According to the National Institute of Mental Health, Panic Disorder is characterized by unexpected and repeated episodes of intense fear accompanied by physical symptoms that may include chest pain, heart palpitations, shortness of breath, dizziness or abdominal distress (Facts). The first panic attack is usually the worst, especially if it is accompanied by severe physical symptoms. It is very similar to a heart attack, and since a person's mind goes into complete induced chaos and fear during such an attack people tend to think the worst, that the end is coming. Panic Disorder is a kind of severe anxiety disorder."

"Carpal Tunnel Syndrome: A Review
Introduction: Definition, Wrist Anatomy, Symptoms, Diagnosis, and Frequency of Occurrence
This research reviews carpal tunnel syndrome. Carpal tunnel syndrome in a medical context is a nerve entrapment disorder (Carpi, 1989). The tendons connecting the fingers to arm muscles pass through a small opening in the wrist, and they are surrounded by synovial sheaths. The synovial sheaths are thin, fluid-filled sacs, which swell when the tendons are overused. The swelling squeezes the median nerve against the wrist bone, or carpal ligament. The wrist is a freely movable joint in which the carpal bones glide across one another. Movement of the bonds is restricted by ligaments. The median nerve provides sensation to the entire hand, and pressure on the nerve causes..."

Abstract
This paper explains how scientists have developed a computer that processes information running on DNA. It discusses how the computer is so microscopic it can't be seen by the human eye. The implications for the future are tremendous, and it is now feasible to believe that sometime in the future, man will become part human and part computer. It discusses how the technology that scientists are currently developing may allow tiny computers to analyze, assess and correct biochemical abnormalities before they manifest themselves as problems.
From the Paper
"Test Tube computers came about as the idea that a computer can be so small that "a trillion of it's kind can fit into a test tube." The idea was developed by researchers at the Weizmann Institute in Israel, who developed a nano-computer that consists of DNA and DNA-processing enzymes which are dissolved in a liquid (Noble, 2001). DNA has always functioned as somewhat of a mini computer, and strands of DNA are so small they can't be detected by the human eye. The discovery has lead researchers to believe that it is possible to perhaps develop a device that is "capable of processing DNA inside of the human body, finding abnormalities and creating healing drugs" (Noble, 2001). A momentous occasional in revolutionary history."
