THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes In Altitude Have A
THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in altitude have a profound effect on the human body. The body attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its complex chemical systems. Any change from this homeostasis is a change away from the optimal operating environment. The body attempts to correct this imbalance. One such imbalance is the effect of increasing altitude on the body's ability to provide adequate oxygen to be utiliz...

Radioactive Wastes, Must For The Protection Of Mankind Be Stored Or Di
Radioactive wastes, must for the protection of mankind be stored or disposed in such a manner that isolation from the biosphere is assured until they have decayed to innocuous levels. If this is not done, the world could face severe physical problems to living species living on this planet. Some atoms can disintegrate spontaneously. As they do, they emit ionizing radiation. Atoms having this property are called radioactive. By far the greatest number of uses for radioactivity in Canada relate n...

These are some of the dreams that have come with the invention of virtual reality. With the introduction of computers, numerous applications have been enhanced or created. The newest technology that is being tapped is that of artificial reality, or virtual reality (VR). When Morton Heilig first got a patent for his Sensorama Simulator i...

Why Do Teens Contemplate To Suicide?
Why Do Teens Contemplate To Suicide? Why do Teens Contemplate to Suicide? As the third largest cause of death between the ages of 15 and 24, the adolescent suicide rate has tripled since 1960. This is the only age group in which an increase has occurred over the last three decades. While there are approximately 10,000 reported teen suicides annually, it is estimated that the number of teen suicides is actually three to four times that number when unreported deaths and ?suicide equivalents? are a...

Crystals
Crystals Crystals What is a crystal? A crystal is a solid substance with definite geometric shapes and molecules that are arranged in a repeating pattern (Compton?s ). Crystals have fixed angles between its faces, which have distinct edges. If the faces of a crystal can reflect light, then it will sparkle (Stangle). Crystals have constant angles because of the regular arrangement of its particles. There are seven types of crystals: cubic, tetragonal, orthorhombic, hexagonal, trigonal, monoclinic...

Love Leads To Death
Love Leads To Death Love = Death What happens when two people fall in love? We may think of love as a sweet heart throbbing fairy tail situation, but in reality, unexpected dreadful circumstances often occur. As a couple falls helplessly in love, they become sexually active. Because of this intimate, uncontrollable love, a couple, with extremely high endodorphine levels may make a poor choice about contraceptives. This poor choice may result in a STD or even the life-concluding virus, HIV/AIDS. ...

Living Thing Biology
Living Thing Biology Living things make up the world as we know it. Living things are involved in our life constantly, seeing that we are alive. There are five characteristics that are common to all living things. Living things are made up of one or more cells. Each cell is made up of living matter and is separated by a barrier that encloses the cell from its surroundings. However, there are many different kinds of cells that make up living things. A single cell can be one organism. These organ...

Chemicals Analysis
Chemicals Analysis Phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi) form a group of four elements in Group 5A of the periodic table. They exhibit increasing metallic properties going down the group. Nitrogen (N), which heads the group, is a colorless, odorless, and tasteless gas. Phosphorus is a highly reactive nonmetal, arsenic and antimony are poisonous metalloids, and bismuth is a true metal. Because of the arrangement of the outer electrons in their atoms, each of these element...

Protein Synthesis
Protein Synthesis The process of Protein Synthesis involves many parts of the cell. Unlike other similar productions, this process is very complex and precise and therefore must be done in proper sequence to work effectively. The slightest error during this process could cause the action to experience difficulty or even fail. For example, in the production of starch, glucose molecules are combined to be stored and eventually utilized as usable chemical energy. The cell can break down the starch...

Silicon
Silicon Silicon is an essential element in humans, found in significant concentrations in hair, bone, epidermis and dental enamel. It is also the second most abundant element on the earth's crust, constituting about 28% by weight.(cite) Many foods and beverages, including certain vegetables, grains, rice, and beer have been shown to contain significant amounts of silicon. Silicone is a synthetic form of silicon and includes 40% silicon by weight. The silicones are synthetic polymers and are not...

Dna
Dna What is DNA? Nucleic acid is a complex molecule found in all cells. There are two types of nucleic acids, deoxyribononucleic acid (DNA) and ribonucleic acid (RNA). DNA is found mainly in the nucleus of cells. RNA may be found throughout the cell. Even bacterial cells which do not have a nucleus, contain both DNA and RNA. Viruses, however, have only RNA or only DNA. DNA plays a vital role in heredity and cell development. It is the substance in genes, the hereditary material that determines a...

Computer Crime
Computer Crime Computer Crime Billions of dollars in losses have already been discovered. Billions more have gone undetected. Trillions will be stolen, most without detection, by the emerging master criminal of the twenty-first century--the computer crime offender. Worst of all, anyone who is computer literate can become a computer criminal. He or she is everyman, everywoman, or even everychild. The crime itself will often be virtual in nature--sometimes recorded, more often not--occurring only ...

Cells Of The Human Body
Cells Of The Human Body Cells are the basic living units of all plants and animals. The cell is the structural and functional unit of all living organisms. There are a wide variety of cell types, such as nerve, muscle, bone, fat, and blood cells. Each cell type has many characteristics, which are important to the normal function of the body as a whole. One of the important reasons for maintaining hemostasis is to keep the trillions of cells that form the body functioning normally. An averaged si...
