Heroin A Long Dark Path
.... significant ways. It does not destroy body organs, like the liver or kidney, the way alcohol does. That is why heroin dependency can last for years. Second, an abuser usually does not die from the symptoms experienced from the withdrawal although it may often feel like the user’s body is being torn from the inside out. This is so unpleasant it drives many addicts back for another hit. The deaths associated with heroin are from overdosing rather than withdrawal. These so-called good differences are now .....

Crystals
.... by crystallization, and the entire boiling mass stiffens as the viscosity increases and the quantity of crystals grows. These two factors determine the termination of the strike, since the deposition of sugar on the growing crystals is impeded more and more as the mother liquor becomes more impure and more viscous.
The concentration of sucrose probably exceeds the saturation point by a considerable degree before crystallization begins. When this critical condition is reached, significantly large nu .....

Basic Discription Of Microbiology
.... pathogen is a disease-producing organism.
They also describe microbes as organisms that are often too small to be seen without the aid of a microscope. Microbes, also known as microorganisms, can be broken down into four classifications that are bacteria, viruses, fungi, and protozoa.
Prescott, Harley & Klein (1990) describe bacteria as prokaryotic cells (cells that lack a true membrane enclosed nucleus). Bacteria are both small and simple in structure; they usually are between o.5 and 5 .....

.... held up a five-pound bag of sugar on national television last month to show how, with an equivalent amount of anthrax, Iraq could eliminate at least half the population of Washington. The US Law Enforcement Assistance Administration reported in March 1977 that a single ounce of anthrax introduced into the air-conditioning system of a domed stadium could infect 70-80,000 spectators within an hour (Hardy 1998). In January 1998, the Center for Disease Control declared that an epidemic hit Miami, Florid .....

Biology Term Paper - Tigers
.... tails to communicate with other tigers.
Where did tigers come from? Tigers (and all other carnivores) are descended from civet-like animals called miacids that lived during the age of the dinosaurs about 60 million years ago. These small mammals, with long bodies and short flexible limbs, evolved over millions of years into several hundred different species, including cats, bears, dogs and weasels. Approximately 37 cat species exist today, including Panthera tigris, the tiger. Tigers evolved in ea .....

There are a many answers to that question but the main ones are:
Ø For agricultural purposes eg space for building. (overpopulation)
Trees are logged for the purpose of space. In this day and age the human race is multiplying and therefore we require more space to expand cites and build more houses. To do this world government cut down any forests in their way.
Ø Industrial \ commercial purposes
Big industries also contribute to deforestation. EG "Macdonald's uses 800 square miles .....

Bipolar Disorder

suicide. The manic episodes are characterized by elevated or irritable mood, increased
energy, decreased need for sleep, poor judgment and insight, and often reckless or
irresponsible behavior. Bipolar affective disorder affects approximately one percent of the
population (approximately three million people) in the United States. It is presented by
both males and females. Bipolar disorder involves episodes of mania a .....

However Rowland and Molina did a marvelous job of defending their results and explaining the significance of these dangerous CFCs to other scientists, government officials, and the press. Eventually the CFC use in aerosols was banned in the US in 1978. However the total ban of the use of CFCs was almost impossible for Rowland and Molina due to scientific confusion and the arrival of the antienviornmental Reagan administration. Another problem that they soon realized was that for example .....

Caustic potash (potassium hydroxide) can be used instead of caustic soda (sodium hydroxide)but is more expensive. The base used to come from wood ash containing potassium carbonate which formed potash as this was not plentiful it made soap a luxury. The cheapest source of the ester is animal and vegetable fats and oils.

After a crude oil is spilled in a marine environment, many processes follow.
Typical crude has a density of about 0.85, more or less, and this factor combined with winds, wave action, and currents leads to spreading, which is very rapid during the first 24 hours. D .....

To put this in perspective, that is approximately 4 football stadiums filled to the top with oil. That is just every year…and this has been going on for more than a decade. In total, 45 million tons of oil in the past ten years that have been put into the oceans. There are several ways that oil ends up in the oceans. One method is through drilling accidents and .....

The tiger lives in several lairs. In one of them the female brings her cubs into the world. From the time they are 8 weeks old, they join their mother on the hunt. At 6 months, they have learned how to kill. They can feed themselves when they are 16 months old.

Fatigue usually sets in with the onset of lactic acid production. Oxygen is carried to the muscle by two delivery systems. Three percent of oxygen is carried in plasma and ninety-seven percent is in hemoglobin, the principal protein in erythrocytes (red blood cells). If hemoglobin amounts are increased, this will lead to increased oxygen levels that can be transpo .....

Around 15 to 20 billion years ago, time began. The points that were to become the universe exploded in the primeval fireball called the Big Bang. The exact nature of this explosion may never be known. However, recent theoretical breakthroughs, based on the principles of quantum theory, have suggested that space, and the matter within it, mas .....
