  • Multiple Sclerosis A Research Paper
    Multiple Sclerosis A Research Paper Introduction Multiple Sclerosis By: Stephanie **** Multiple Sclerosis (MS) is a chronic, often disabling disease that randomly attacks the central nervous system (brain and spinal cord). The progress, severity and specific symptoms of the disease can not be predicted; symptoms may range from tingling and numbness to paralysis and blindness. MS is a devastating disease because people live with its unpredictable physical and emotional effects for the rest of the

It mostly deals with our behavior, as well as speech, movement, coordination, and basically any part of our life in general is associated with it. As we study the brain more and more over the last twenty years, we begin to discover more and more about it and its hundreds of thousands of complex and involved tasks.

    Managing People with AIDS Today, AIDS is the second leading cause of death among adults between the ages of 25 and 44. With more than half of the nation’s 126 million workers in this age group, managers cannot afford to ignore this deadly disease.

We have two opposite opinions fighting each other, those who are pro marijuana and those who are anti-marijuana. These two sides have been fighting on this issue for years.

  • Save the Rainforests
    Save the Rainforests The destruction of the rainforests is one of the most crucial environmental issues of our time. It is also one of the most misunderstood and neglected. There has been so much propaganda and publicity attached to this crisis that “Save the Rainforests” is becoming almost as cliché as “Save the Whales.” Why don’t we take this problem more seriously? Is it because we, as Americans, simply don’t understand the devastating, long-terms consequences that continued deforestation of

It’s been controversial because of the bad track record it has sustained over the years. Marijuana is considered to be a schedule one drug. That means that it has a high potential for abuse and lacks an acceptance for legal medical use, as it is clearly stated under the controlled substance act. It is estimated that 200,000,000 people have consumed the drug worldwi

    Multiple Sclerosis Multiple Sclerosis is a disease of the central nervous system, the nerves that make up the brain and spinal cord. This disease is commonly known as MS. Its cause is unknown, it cannot be prevented, and neither a cure or a safe and effective treatment has been able to halt its progression so far. It is not fatal, and much progress is being made in treating symptoms and identifying mechanisms that trigger this disease. Sclerosis comes from the Greek word skleros, which means har

Over the years there has been a huge "food fight" concerning the safety of NutraSweet and other artificial sweeteners. In the eyes of the consumer the safety of such products is questionable.

    Euthanasia13 Many people confronted with a terminal illness are confused about what they can do as a dying person. This is when euthanasia is often discussed. Deciding that this is the only option is a long drawn out process. Being that a large part of American society is of Christian beliefs, it is necessary to look at morality based on religion. The main pro-suicide argument deals completely within the issue of choice. If life is seen as a covenant, or temporary loan from God, the freedom to c
