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 this particular
shape, could not be used as an effective saw. However, use-wear patterns

Flourescence In-situ Hybridisation And Its Advantages
Number of words: 235 | Number of pages: 1.... instead
of amniotic fluid. The problem with amniocentesis is it uses a hollow needle to
take fluid from the mother's uterus. The needle could damage the developing
fetus if not inserted properly. Another advantage of FISH is that the parents
get a much quicker test result than amniocentesis. After the sample is taken,
amniocentesis can take up to three weeks before a test can be administered.
With FISH, a same day result is given, which is much more convenient to the
parents. Additionally, FISH is a simpler process. It uses specially prepared
molecules which bind to specific regions of DNA. To find a particular gene, the
exam .....

Acid Rain
Number of words: 1273 | Number of pages: 5.... southern regions that are near the Great Lakes, such
substances as limestone or other known antacids can neutralize acids entering

little top soil, there is not enough buffering capacity to neutralize even small
amounts of acid falling on the soil and the lakes. Therefore over time, the
basic environment shifts from an alkaline to a acidic one. This is why many
lakes in the Muskoka, Haliburton, Algonquin, Parry Sound and Manitoulin
districts could lose their fisheries if sulphur .....
