Alcohol Facts and statistics ( www.niaaa.nih.gov-2012 ) Global Burden of alcohol abuse‚ In 2012‚ 3.3 million deaths‚ or 5.9 percent of all global deaths (7.6 percent for men and 4 percent for women)‚ were attributable to alcohol consumption.. Alcohol contributes to over 200 diseases and injury-related health conditions‚ most notably alcohol dependence‚ liver cirrhosis‚ cancers‚ and injuries. In 2012‚ alcohol accounted for 5.1 percent of disability adjusted life years (DALYs) worldwide. Globally‚

Presence of Alu element within PV92 on chromosome 18 in a mixed ethnical population and its connection with humans’ ancestral origins By Shiyu Song Biology 155Q LAB-A: 14:30-17:30 Dr. Jacob April 17th 2013 Abstract The Alu insertion (+) within PV92 on chromosome 16 usually reflects a person’s ancestral origin. This study aimed to find the correlation between the presences of Alu insertion (+) within PV92 on chromosome 16 within a population. We used PCR to detect the Alu insertions

Mr. Mihordea Motion of Atoms and Molecules lab summary In this lab the standard heat of combustion of magnesium was calculated by using the calorimeter. Also‚ the point of combustion of magnesium was to see how much heat would be released from fireworks such as sparklers. The concept of this lab was to find the difference in temperature from the beginning to end of combustion of magnesium and calculate the standard heat

Ketchup Lab Report Problem: People visiting fast food restaurants complained that ketchup was dripping onto their fingers and clothes. What could we do to insure that the ketchup will not drop all over the customers? Hypothesis: If I put one ketchup packet in a hotter bath then it will move faster down the styrofoam plate. Independent Variable: The temperature Dependent Variable: The viscosity of the ketchup’s “runniness” Constants: The type of ketchup

determination of these forces is not practical but the presence of the forces can be allowed for by using a property known as the coefficient of restitution. The coefficient of restitution is the ratio of speeds of a falling object‚ from when it hits a given surface to when it leaves the surface. In laymen’s terms‚ the coefficient of restitution is a measure of bounciness. It basically is a property of collisions and depends upon the materials that are colliding. In this experiment‚ the coefficient

Maria Martinez Anatomy and physiology II TTH 2:20 “Demonstrating the Importance of Surfactant: Lab Report” Introduction Surfactant is an essential component for the respiratory system to function properly. This experiment was administrated to help us understand better the role of surfactant in the alveolar system. Surfactant is a detergent-like substance produced by the Type II alveolar cells in the alveoli. Surfactant is produced to make it easier for people to breath by reducing the surface

The classroom light was our control cup during the lab. Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general. As I did more research on photosynthesis‚ the Calvin Cycle‚ wavelengths and pigments required for a proper equation

The purpose of the lab was to measure the effectiveness of antacids at neutralizing excess stomach acid. A neutralization reaction is when an acid and a base react to form water and salt. To illustrate‚ H+ hydrogen ions from the acid react with the hydroxide ions OH- from the base. Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion

Exocytosis Lab Report Rough Draft Abstract: In Paramecium caudatum‚ trichocysts are 10^3 secretory vesicles that are released from the cytoplasm. We first observed how the presence of Alcian blue dye triggers normal secretion of trichocysts‚ and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is
