... 100,000 deaths annually in the United States, and although the number shows little sign of declining, the rate per 100,000 population has decreased since the early 1980s. Accidents, mostly due to drunken driving, accounted for 24 percent of these deaths in 1992. Alcohol-related homicide and suicide accounted for 11 and 8 percent. Certain types of cancer that are partly attributable to alcohol, such as those of the esophagus, larynx, and oral cavity, contributed another 17 percent. About 9 percent due to alcohol-related stroke. Many studies have been made about attitudes toward drinking in different societies. Various surveys show that subgroups within a society or culture do not all have ...

American Dream America, our great country, is strong, powerful, and influential. Americans exemplify positive values, selflessness, hospitality, and the American way of life. The mighty oak tree that stands taller, bigger, and older than all others best represents this grand country. Each part of the tree illustrates a facet of our nation. Shapely emerald leaves covering the tree symbolize the values many Americans hold concerning themselves, others, and their nation. Leaves help the tree grow and flourish just as our value of caring for our neighbors help us to unite and become more successful as a whole. The beautiful shade and distinct shape of these leaves make the tree more attractive a ...

An estimated 146,000 Americans died of lung cancer in 1992, and 90 percent of these deaths were caused by cigarette smoking. Smoking is responsible for about 30 percent of all cancer deaths annually in the United States more than 155,000 each year. If smoking-related cancers could be eliminated from our society, we would see a significant decline in the annual cancer death rate instead of small but steady increases. Since 1964, the year of the Surgeon General's first report on the health risks of cigarette smoking, strong evidence of the association between smoking and cancer has accumulated. Countless studies have proved that smoking causes lung cancer, and we now know that it substantially ...

Animal Species Living creatures on Earth need three basic things in order to survive: the ability to eat, breath, and reproduce. All animals are able to do so. Animals are divided into species, among these species are: Mammals, Reptiles, Arthropods, and Aves. Mammals, also known as Mammalia, come from Latin meaning mamma breast. They are called this due to the fact that Mammals are the only animals which have mammary glands, which enable them to nourish their young solely on milk secreted from these glands. Mammals are warm blooded, and all, except for marine mammals, are mostly or completely covered with hair. Mammals give birth to live young, however, there are a few rare exceptions to thi ...

Animal Testing Traditionally, animals have been used to ensure the safety of our consumer products and drugs. Yet around the world, scientists, regulators and animal protectionists work together to develop alternatives to their use. The use of animals in the life sciences dates back to ancient Greece and the earliest medical experiments. To learn about swallowing, physicians cut open into the throat of a living pig. To study the beating heart, they cut open into its chest. For centuries physicians and researchers used animals to enhance their knowledge about how the various organs and systems of the body functioned, as well as to hone their surgical skills. As long as animals have been used ...

... The land around the lakes was fertile but not large enough to produce food for the population, which expanded steadily as the empire grew. To make more land suitable for farming, the Aztec developed irrigation systems, formed terraces on hillsides, and used fertilizer to enrich the soil. Their most important agricultural technique, however, was to reclaim swampy land around the lakes by creating chinampas, or artificial islands that are known popularly as floating gardens. To make the chinampas, the Aztec dug canals through the marshy shores and islands, then heaped the mud on huge mats made of woven reeds. They anchored the mats by tying them to posts driven into the lake bed and plant ...

In 1882 Robert Koch discovered that the connection between human and animal Tuberculosis actually were established. When Koch realized that children were becoming infected from contaminated cows milk most nations brought out legal instruments designed to remove chronically infected animals and take a look at the public health aspect of the problem. The Disease Mycobacterium bovis is the bacterium that caus ...

I will be covering general information about the bear such as their size, weight, color, food, etc., but I will concentrate mainly on the hibernating cycle of the black bear. There are from 400,000 to 750,00 black bears in North America, and they weigh from 130 to 660 pounds with a body length of 50 to 75 inches. Their colors vary from black, chocolate brown, cinnamon brown, pale blue (known as glacier bears) to white. Black bears will often have a brown muzzle and may have a lighter color patch on its chest.

Cave Art At the foot of a cliff in the Ardche Gorges, in south-eastern France, amateur speleologists discovered the world's oldest painted prehistoric cave. Discovered on December 18, 1994, this cave features art that dates back thirty-one thousand years. Jean-Marie Chauvet, Eliette Brunel-Deschamps and Christian Hillaire, were the amateurs who discovered the cave that has come to be known simply as the Chauvet cave. The explorers were in Vallon-Pont-d'Arc, France some thirty feet below ground. While exploring a cave, they were intrigued by a draft of air. They followed the draft to the source and discovered a cavity. This cavity then led to a vast network of galleries and rooms. The explore ...

Circuit Breaker Abstract A circuit breaker was examined to determine how it works. Basically, it is designed to disconnect the current if the current passing through the breaker is higher than the allowable current. Its main parts consist of a switch, connecting pads, and the disconnect device. Since the breaker consists of many individual parts, the only improvement found was to combine some of the parts into a single part. Introduction Our group dissected a thirty-amp household Circuit-breaker. Its purpose is to protect electrical appliances from being damaged though excessive currents. A circuit breaker limits the amount of current that may safely enter a household electrical system via a ...

Clinical Chemistry In Medicine Of the diagnostic methods available to veterinarians, the clinical chemistry test has developed into a valuable aid for localizing pathologic conditions. This test is actually a collection of specially selected individual tests. With just a small amount of whole blood or serum, many body systems can be analyzed. Some of the more common screenings give information about the function of the kidneys, liver, and pancreas and about muscle and bone disease. There are many blood chemistry tests available to doctors. This paper covers the some of the more common tests. Blood urea nitrogen (BUN) is an end-product of protein metabolism. Like most of the other molecules i ...

Hair follicle testing is a drug testing method that is perhaps, less demeaning, less invasive, and less likely to be tampered with than the well-known urine test. Although, it is more reliable than urine testing it has its problems that need to be addressed. It is necessary for one to understand how hair grows to be able to understand the testing procedure. Hair grows within a small cavity known as the hair follicle. Hair growth occurs when cells divide in the matrix near the bottom o ...

First we had to get a 95% full part. These parts were weighed before the hold pressure was added. The hold pressure was added and parts were weighed with the high, low, and optimum hold pressure. We also recorded the peak cavity pressure max, min, average, and standard deviation for the optimum parts. This procedure was repeated for the same mold with one blocked cavity ...
