INTRODUCTION The purpose of this project paper is to highlight the chemistry and science of the very curious material: Kevlar®. Our aim is to create a very informative piece of writing that can be of reference to our project subject‚ when in need. Upon taking up this project we conducted some very superficial research initially. Our research led us to believe that Kevlar® is a rather well known material that has been used in bullet proof vests for the last couple of decades. In addition to

Kristine Thomas Professor Lee Bio 120-171 November 25‚ 2012 “Alternative cancer treatments” Is radiation therapy and chemotherapy the best resources out for the fight against cancer?” Cancer has been around for most of human history. Evidence of cancer has been discovered in fossilized bone tumors‚ as well as in human mummies from ancient Egypt. Western medicine has made great discoveries toward cancer treatment‚ but I often wonder

coefficient of 6.22 x 106 sq cm/mole (5). Protein was determined by the method of Stadtman et al (14). In preliminary experiments‚ the well known fact that the respiration of S. faecalis is not inhibitedl by cyanide (9‚ 11) was confirmed using 0.001NM HCN. Following this‚ the effect of oxygen concentration on the oxygen consumption of whole cells was determined manometrically. The respiratory rates in vessels gassed with 5‚ 20 and 100 % O2 showed only slight differences‚ whether the vessels were gassed
