Beta blockers (β-blockers or BBs) were invented and designed by Sir James Black‚ who was a Nobel Prize winning scientist. Black designed beta blockers to counteract stimulated adrenergic effects. He demonstrated that‚ by blocking the cardiac beta-receptors‚ these agents could cause inhibitory effects on the sinus node (chronotropic effect)‚ atrioventricular node (dromotropic effect)‚ and on myocardial contractility (inotropic effect).1 It is important to note that not all beta receptors (β-receptors)

Fischer Esterification Kyle Peterson Chem. 243a Matt Judd‚ Sec. 25 Date Performed: 10/15/03 Abstract: The objective of this experiment is to efficiently perform a fischer esterification of 1-Hexanol to form water and hexyl acetate‚ and to confirm the esterification with a nuclear magnetic resonance (NMR) spectroscopy. It was found that 0.3963 grams hexyl acetate was formed with a percent yield of 33.2%. The product was confirmed using NMR‚ IR‚ and boiling point confirmation. Backround: A Fischer

Hans Fischer is a well known chemist who was awarded the Nobel Prize for chemistry in 1930. The animal’s’ natural coloring matter‚ tissue of plants‚ and red blood pigments is what Hans Fischer dedicated his scientific career to. Because Hans Fischer’s father was the director of the chemical dye‚ Hans was well acknowledged of the color of chemicals‚ which is known as the chemistry of color. Hans Fischer was one of the best chemist‚ because he was awarded the Nobel Prize‚ researched biological pigments

Calculating Beta for Compuware Corporation Financial websites tend to calculate beta on securities differently for publicly traded companies. Beta is merely an estimable measure of an assets’ risk in relation to the market. Because each website has their own underlying assumptions‚ they compute beta to have different values. In some cases‚ the variance in beta is as large as 0.50. To find out what underlying assumptions websites used to compute their betas‚ we performed a series of regression
