Tigers
Tigers The tiger is part of the kingdom Animalia, phylum Chordata, class Carnivora, family Felidae, subfamily Panthernae, genus/species Panthera tigris. Tigers have round pupils and yellow irises (except for the blue eyes of white tigers). Due to a retinal adaptation that reflects light back to the retina, the night vision of tigers is six times better than that of humans. Like domestic cats, tiger claws are retractable. Tiger scratches on trees serve as t...

Tourette Syndrome
Tourette Syndrome Tourette Syndrome How would you feel if you were diagnosed with a disease that has baffled scientists for centuries? If your entire social life was destroyed due to this disease which may worsen as time goes by. But worst of all about being diagnosed with this disease is the fact that there is no cure. My guess is you wouldn�t be too happy. You would probably become very depressed, violent, and cut yourself out from any social activities. If you felt this way, you ...

Transmission of Aids
Transmission of Aids INTRODUCTION As we all know, AIDS (Acquired Immune Deficiency Syndrome) is a fatal infection caused by the Human Immunodeficiency Virus (HIV). The virus attacks the body's immune system and, over a period of time, destroys it. This disables the body's ability to fight off infections by other germs and the growth of cancers, eventually resulting in death. HOW IS HIV SPREAD? HIV is spread through the exchange of bodily fluids, which contain a high large amount of...

Types Of Microphones
Types Of Microphones Types Of Microphones Basically this section that I read told about different types of microphones, what they can do and what they can not do. It told us that microphones were contained metal diaphragms that vibrate when the sound waves hit them, the vibrations are converted into electric impulses by back plates or coils. The impulses can be amplified, and recorded on the videotape, and can be recorded and stored there for editing along with the pictures. Next the...

The Use of Pollen Analysis in
The Use of Pollen Analysis in The remains of ancient plants can provide a wealth of archaeological information about a site, with many methods being available to the archaeologist engaged in extracting this data. Perhaps one of the most widely-known of these techniques, possibly because of its attractive nature, is pollen analysis - a technique developed in the early years of the twentieth century by, like so many archaeological techniques, a geologist -- the Norwegian Lennart van Post. To...

The Y2K Problem
The Y2K Problem The Y2K Problem!!! What is Y2k? In one sentence, Y2k is "...the inability of computer programs at the year 2000 to interpret the correct century from a recorded or calculated date having only two digits to indicate the year".[Center for Computer Systems Engineering] What does that mean? It means that many of our computer systems, although sensitive to date and time, have been programmed with a piece missing -- the century portion of the date. These systems were crea...

The physics of a crystal
The physics of a crystal The Physics of a Crystal Most simple chemical compounds consist of crystals. If you were to examine a lump of crystalline material very closely, you would be able to see tiny individual crystals. All crystals have a definite geometric shape, determined by the way the atoms are linked together. Mineralogists recognize 32 different classes of crystal, which are grouped into seven crystal systems. Crystal systems are described by their axis, which are imaginary ...

The prospect of cold fusion
The prospect of cold fusion The Prospect of Cold fusion In March of 1989, Drs. Martin Fleischmann and Stanley Pons first announced that they had discovered a way of producing heat from metals supersaturated with heavy water. Thus at the University of Utah, cold fusion was discovered. In the weeks following this announcement many other scientists tried to replicate the same experiment, with little result. After many scientists and Universities came up empty handed, the possibility of c...

What is this great event that would have such an impact on the world that it could end civilization? The problem is a simple computer bug refereed to as the Y2K bug but its ramifications could be immense. This computer bug has been predicted to impact the world anywhere from a minor problem to the end of a civilization. Whiche...

The Effects of Acid Rain on Lakes and Trees
The Effects of Acid Rain on Lakes and Trees The Effects of Acid Rain on Lakes and Trees Acid rain has long been argued by society�s most formidable minds. It indirectly destroys ecosystems that surround forests and lakes (Taylor, 26). People need to make decisions dealing with the destruction of nature and the role acid rain plays in it. Acid rain destroys millions of forests and lakes (Taylor, 26 ). Studies show that acid rain is one of the largest contributing...

The General Effects of Fire on
The General Effects of Fire on The General Effects of Fire on Wildlife Abstract: Fire is an important part of many ecosystems and helps maintain the condition of habitats for wildlife. The effect of fire depends upon many factors, varying from the type of wildlife to their different habitats. Fire affects ungulates through positive, but often, short-lived improvements in diets by allowing ungulates to consume new plant growth. Fire mediates species interactions thereby reducing con...

The Jovian Planets
The Jovian Planets The Jovian Planets Far beyond Earth in the solar nebula lies an ice belt and beyond that lay the four Jovian planets. They are Jupiter, Saturn, Uranus and Neptune. Jovian means "Jupiter- like" in which the rest of the jovian planets do coincide with the name. Uranus Neptune and Saturn, all carry the same traits as Jupiter. The jovian planets are large gas giants that contain mainly a thick atmosphere of Hydrogen and helium. These planets do not have solid surfaces,...

Technology and the future of w
Technology and the future of w Technology and the Future of Work Every society creates an idealised image of the future - a vision that serves as a beacon to direct the imagination and energy of its people. The Ancient Jewish nation prayed for deliverance to a promised land of milk and honey. Later, Christian clerics held out the promise of eternal salvation in the heavenly kingdom. In the modern age, the idea of a future technological utopia has served as the guiding light of...

The Aging Process
The Aging Process The Aging Process Why should the human body give out after 70, 80, or even 120 years? Why are older people more susceptible to disease, more inclined to have impaired vision and hearing, and likely to lose some of the physical and mental capacity they once enjoyed? There are no fully satisfactory answers to these questions. Although we are mortal, it is entirely possible that one day humans could live much longer. The present potential life span for humans is said to...

The Atomic Theory
The Atomic Theory The Atomic Theory In this report I will give a history on the development of the atomic theory. I will cover some of the most important dates in the development of atomic theory. An atom was first thought of by the Ancient Greeks who believed that matter was made of smaller particles called elements. The name they gave to these particles was the atom. In 1776 the man known as "The Father of Atomic Theory", John Dalton was born in England. He is known a...

The Critical Role of informati
The Critical Role of informati The Critical Role of Information Systems Today�s information systems are both technical and social in nature. Management must understand the importance of information within the organization. It is management�s job to understand how information is collected, processed, and distributed. We are all extremely affected by information systems and must be willing to understand and work with them. Our global economy does not allow us to depend on face to ...

Sickle Cell Anemia
Sickle Cell Anemia Sickles Cell Anemia in Children (10 pgs) In 1904 a hospital intern at The Presbyterian Hospital in Chicago Illinois, Dr. Earnest Irons, who was the first physician to describe sickle cells, wrote a report on Walter Clement Noel�s blood. Also in 1904, Dr. James B. Herrick, a Chicago Physician, treated a twenty- year-old college student from the West Indian islands of Grenada. The young man went to Herrick complaining of shortness of breath, heart problems, abnormal...

Taking the Pill Depression and
Taking the Pill Depression and Taking the Pill: Depression and Social Stigma Depression is widespread in today's society and is called 'the common cold of mental health problems.' But despite its prevalence, people are wary about the use of a pill in order to chase the blues away. Some even liken anti-depressants to Soma as depicted in Aldous Huxley's Brave New World. Soma is the perfect pleasure drug that provides a mindless, inauthentic happiness, which makes people comfortable...

Technology The End of Mankind
Technology The End of Mankind Technology: The End of Mankind TECHNOLOGY The human race is slowly, but surely, contributing to its own demise. This sub-conscious suicide is being carried out in more than one way, but the most apparent one is technology. Technology is advancing at a pace so rapid that it will eventually lead to the self-extinction of the human race. The most current and pressing issue that falls into this category is the infamous Y2K bug. This is the virus...

Quantum Computing
Quantum Computing Fury of the Quantum Fist Quantum mechanics will be our most powerful tool in the world of tomorrow. For those of you that did not know this, quantum mechanics is a physics system or theory using the assumption that energy exists in discrete units. It is probably no exaggeration to say that quantum mechanics is the most successful scientific theory in history. This has been a great success, but in spite of the fact the origins of the quantum theory stretch back nearly a...

Rustproofing
Rustproofing One method used to prevent rust, is to insulate the metal from moisture and oxygen by covering it with protective chemical layers or paint. This method is effective as long as the protective surface is not damaged, for example, stone chips, scratches, abrasions in the joints. In real terms this is not possible and where damage occurs, no matter how small, rust will occur. It is also impossible to cover every area on the vehicle with this method and hard to reach places are left...

Rutherford
Rutherford Ernest Rutherford was born in Nelson, New Zealand. Rutherford demonstrated his abilities as a scientist early on while working on his B.Sc. at the University of New Zealand in 1894. He showed that the magnetization can be removed from a magnetized iron needle by dissolving the surface layer of the metal in acid. He began work at Cambridge in 1895 and was a professor at the University of Manchester from 1907 on. It is during this time period that Rutherford made his m...
