... cover the Exxon people’s taping.14 As bad as the Valdez disaster was, Exxon made five billion dollars of revenue during the 1989 operating year. Of that, they spent three billion over the next several years on the clean up. During the cleanup, Exxon employed the assistance of 12,000 people and 1,385 ships and planes. They recovered a little over 2.6 million gallons of oil from Prince William Sound over the cleanup period. The estimated number of dead birds was 33,126 along with 138 eagles and 980 otters. Usually, when we are thinking of oil pollution what comes to mind is maybe a disastrous oil tanker spill somewhere in an ocean that ends up killing thousand upon ...

... Adenosine deaminase (ADA) deficiency, a severe combined immune deficiency, also known as the "Boy in the Bubble disease." ADA deficiency is a result of inheriting two copies of the defective ADA gene. Possession of a normal gene leads to the continuous, regular production of ADA in cells throughout the body. Without at least one properly functioning gene, children have no way of converting deoxyadenosine (a waste product) into inosine. This leads to the rapid build-up of deoxyadenosine in the system, which becomes phosphorlyzed into a toxic triphosphate, which kills T-cells. The result is an almost complete failure of the immune system and early death. Previ ...

... attention. Arthritis is not exclusive to the elderly; more than 30,000 Canadian children already have some form of it, and another 1,000,000 with the disease between 30 and 50 years of age. Climate and weather has little, if anything, to do with the disease other than a psychological impact on the course of the disease. And, arthritis is a disease for which something can be done. Types As I have already stated, there are more than 115 different types of arthritis. I will include the six most common forms in this report. Osteoarthritis Osteoarthritis is the most common form of arthritis in Canada. This type is also referred to as "degenerative jo ...

... what made these animals move to Tasmania which the never reached. es donÕt form packs like other wild dogs, they either live alone or in small families. es mate for life and mate once a year. The families have home territories that they rarely leave. families may co-operate to catch large animals. es chase their prey. They wear them out in a long chase because they arenÕt very fast runners. Large animals are chased until the es can catch them or until the weaker ones drop back. es donÕt always get their prey, however kangaroos can lean back on their tails and kick hard enough to rip open a Õs stomach. The gestation period of the is about 63 days, an ...

... do not possess gills flaps like a fish so a shark must continuously move in order to obtain enough oxygen to survey. The large teeth of a shark are evolutionarily derived from jagged skin scales. Which are apparent on shark’s ancestor’s Placodermi class. The digestion system of a shark contains a “spiral valve” intestinal system, which increases the surface area and lengthens the time food is digested in the unusually short intestine system of a shark. Sharks sexually reproduce. Unlike a shark, rays have flattened bodies so they can hide themselves in the sand at the bottom of any shallow water area and wait for a meal. Rays also have a ...

... their mouths. They have a small head, with a straight snout and cleft upper lip with bristly hairs. Adults can grow up to 15ft (4.6 meters) but they usually only grow to about 10 feet. They weigh an average of 1300 pounds. Manatees live in small family groups sometimes up to herds of 15-20. After a gestation of up to 6 months, usually a single pinkish calf is born. Manatees ferquently communicate by muzzle to muzzle contact and when alarmed they emit chripy squeaks. The number of manatees has been reduced over the past several years due to heavy hunting for their hides, meat, and blubber oil. Some governments, including the United States, have placed the m ...

... in North America this year. Such crops are expected to triple in use worldwide in the next few years, he writes. The projections quoted by Prof. Mitchell may not materialize. The European Union will not accept GM products, and this is causing horrendous marketing problems for North American farmers. It is becoming obvious we cannot force Europeans to take such products, even though Canada and the U.S. are using the World Trade Organization (WTO) in an effort to do so. Most large European and British supermarket chains have removed GE products from their shelves, and the largest European food processors (Nestle and Unilever) will no longer use GM products. All t ...

... and ranged from six to ten interviews for each subject. The questions asked focused on the subject's life accounts in their post adolescent years. The interviews focused on topics such as the men's background (education, religion, political beliefs) and major events or turning points in their lives. Levinson's concept of life structure (the men's socio-cultural world, their participation in their world and various aspects of themselves) is the major component in Levinson's theory. The life structure for each person evolves through the developmental stages as people's age. Two key concepts in Levinson's model are the stable period and the trans ...

... the years there has been a growing focus on biological etiology. Combinations of psychotherapeutic and medical treatments, as well as comprehensive educational treatment provide the best care and placement of both adults and children afflicted with . Adult psychotic disturbances were noted in the early twentieth-century classifications of mental disorders (Nelson, Israel, 1997). The descriptions and classifications of these disturbances, however, were confusing and controversial. Kraeplin set the basis for modern classification. He used the terms dementia, a belief that progressive deterioration occurred, and praecox, meaning the disorders began early. Late ...

... is the table and the balls, and the law then implies that the total momentum of the balls just before they collide is the total momentum just after the collision. Therefore if the masses of two colliding objects are known, the velocity and the velocity of the other before the collision, you can calculate the final velocity of this second object after it has collided. To obtain an exact answer however, we must find out what type of collision takes place, whether it is elastic or not elastic. The type of collision is characterized by what is called the coefficient of restitution. This quantity is approximately constant for a collision between two given ...
