.... to use as a saw. A small round twig, a centimeter thick, from a local deciduous tree was used as the wood subject. The exact species of the tree is unknown; however, it was a very hard wood and a light brown/tan color. Initially, medium pressure was used on the flake and it was moved in bi-directional strokes across the stick. After about thirty strokes, the use edge angle prohibited the flake from cutting further in to the stick. The cut was roughly three millimeters deep and three quarters millimeters wide. It could be determined that a tool, in t .....

.... the background material, a great deal of questions may arise as to how exactly this disease is spread from person to person and what conditions promote infection. For example, one may wish to investigate the following: 1) Mycobacterium leprae as yet to be cultured in laboratory media? Why? 2) Why is leprosy so prevalent in some parts of the world (i.e. India) but not in others? 3) How does leprosy become so widespread in a population? 4) Despite the discovery of drug treatments, why are over million people still infected? 5) Is there a genetic predisposi .....

.... to 50 eggs. The eggs are very small and deposited in cracks and crevices. A female normally lays less than 100 eggs during her life span . Under ideal conditions, the eggs hatch in two weeks, but may take up to two months to hatch. The young nymphs are very much like the adults except for size. Several years are required before they are sexually mature, and they must mate after each molt if viable eggs are to be produced. Populations do not build up rapidly because of their slow development rate and the small number of eggs laid. ECONOMIC IMPORTANCE: Silverf .....

.... ratio from the experimental you find the error. Error is the deviation of the experimental ratio from the accepted ratio. After I had the error I could go on to find the percentage error. The equation I used was, error divided by the accepted ratio times 100. For example, if I took the error of the experimental ratio for the paper towels, which was 0.12. I took that and divided it by the accepted ratio giving me .03821651. Then I multiplied that by 100 giving me about 3.14. Using these steps I found the percentage error for all of the objects measured. T .....

.... that respectively encode the viral DNA-polymerase, envelope protein, pre-core protein (which is processed to viral capsid) and protein X. The function of protein X is not clear but it may be involved in the activation of host cell genes and the development of cancer. Hepatitis B is a serious public health problem that affects people of all ages in the United States and around the world. Each year, more than 240,000 people contract hepatitis B in the United States. A highly infectious virus that attacks the liver causes the disease. (HBV) infection can lead to severe illness, liver damage, and, in some case .....

.... the acids fall to the earth in any form it will have large impact on the growth or the preservation of certain wildlife. NO DEFENCE Areas in Ontario mainly southern regions that are near the Great Lakes, such substances as limestone or other known antacids can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre©Cambrian Shield, with quartzite or granite based geology and little top soil, there is not enough buffering capacity to neutralize even small amounts of aci .....

.... social cirles. Alcohol penetraes all ages, educational, occupational, and socioeconomical boundaries. Each year it is estimated that ten percent of all deaths are related to alcohol abuse. Am astonishing fifty percent of all major automobile accidents, and murders are associated with alcohol. On and on the statistics point to the enormous dangers of alcohol, yet it is a legalized drug. As bleak as this problems seems to be on society as a whole, it is also rueful for the poor soul who is alcohol dependent. The life span of the alcoholic is about ten years s .....
