The People of the Kalahari Desert Part One Introduction, Location and Environment The people of the Kalahari desert are extraordinary people. For centuries their hunting and food gathering techniques have enabled them to survive in the difficult environment of the dry, hot and barren Kalahari desert. They are known as the Bushmen. Or the Kung or the Gikwe since Bushmen is rather discriminating because the Bushmen live among shrubs and trees and sand and such. The people of Kalahari Desert live
HYPERTENSION
HYPERTENSION
HYPERTENSION ************************************************************** Blood pressure Blood pressure is the force with which your heart pumps blood through the body. Occasional increases in blood pressure levels are not unusual. Hypertension Hypertension is high blood pressure. When heart beats (contracts and relaxes) it pumps out a certain volume of blood. The maximum arterial pressure, measured in mm Hg, determines the systolic reading and the lowest reading of this pressure is called t

Analysis Of The Chernobyl Meltdown
Analysis of the Chernobyl Meltdown On April 1986, Soviet's Union Chernobyl nuclear plant exploded letting out a massive amount of radiation that would debate of all Russian citizens for hundreds of years to come. At exactly 1:21 am. on April, 1986 inChernobyl, a city near the Pripiat River the No. 4 reactor exploded and released thirty to forty times the radiation of the Nagasaki and Hiroshima bombing. The exact causes of the explosion are not known , however scientists and researchers, under th
A ROSE FOR EMILY
A ROSE FOR EMILY
A ROSE FOR EMILY A Rose for Emily takes place after the Civil War and into the 1900?s in the town of Jefferson, Mississippi?a town very similar to the one in which William Faulkner spent most of his life. It is a story of the conflict between the old and the new South, the past and the present?with Emily and the things around her steadfastly representing the dying old traditions and the present expressed mostly through the words of the narrator but also through Homer Barron and the new board of
Active Transport
Active Transport
Active Transport Since the cell membrane is somewhat permeable to sodium ions, simple diffusion would result in a net movement of sodium ions into the cell, until the concentrations on the two sides of the membrane became equal. Sodium actually does diffuse into the cell rather freely, but as fast as it does so, the cell actively pumps it out again, against the concentration difference. The mechanism by which the cell pumps the sodium ions out is called active transport. Active transport require
Acid Rain
Acid Rain
Acid Rain Acid rain is a serious problem with disastrous effects. Each day this serious problem increases, many people believe that this issue is too small to deal with right now this issue should be met head on and solved before it is too late. In the following paragraphs I will be discussing the impact has on the wildlife and how our atmosphere is being destroyed by acid rain. CAUSES Acid rain is a cancer eating into the face of Eastern Canada and the North Eastern United States. In Canada, th
INTERNAL-COMBUSTION ENGINE
INTERNAL-COMBUSTION ENGINE
INTERNAL-COMBUSTION ENGINE INTRODUCTION Internal Combustion Engine, a heat engine in which the fuel is burned ( that is, united with oxygen ) within the confining space of the engine itself. This burning process releases large amounts of energy, which are transformed into work through the mechanism of the engine. This type of engine different from the steam engine, which process with an external combustion engine that fuel burned apart from the engine. The principal types of internal combustion

Concepts of Lifetime Fitness September 1, 1997 Homeostasis is the state of equilibrium in which the internal environment of the human body remains relatively constant. Two excellent examples of homeostasis are how the body maintains a constant temperature and blood pressure during strenuous physical activity or exercise. Although there are many other activities in the body that display homeostasis, I will only discuss these two. Temperature in the human body is usually kept at approximately 37 d

Synthesizing Artificial Organs: The Future of Transplantations Biomedical engineering is the marriage and offspring of engineering and medicine. As the name would suggest, the field revolves around developing and producing medical devices. A medical device, however, is a rather broad term in regards to this field beca use everything from catheters, to cochlear implants, to prosthetic arms falls under this category. In addition, an up and coming sub-field of biomedical engineering is that of tis

Blood Pressure The A ffects of Physical Activity on Blood Pressure Introduction The heart is a muscle that pumps blood into the body ' s organs and tissues. Blood is pumped out of the left side of the heart into the arteries - the blood vessels that carry the blood ' s oxygen and nutrients to your body. As the blood pumps out of the heart and into the arteries, it pushes against the artery walls. Blood pressure is the measurement of the pressure of the blood in the artery. Blood pressure measure
