Social scientists have studied it‚ lawyers have tried to fix it and post-feminist society is over it. But women are still outnumbered by men in math‚ science and engineering fields. Most overt discrimination against women in the sciences has been reduced or eliminated in recent decades through legal‚ academic‚ corporate and government measures. But a climate that is less than fully friendly to women remains‚ and its texture is often still so taken for granted that it tends to be invisible. The

more and more types of technology improvements are happening. Now‚ we have our cell phones‚ computers‚ video gaming system and the internet. “Many say that teens have taken laziness to a whole new level due to our increasing use of technology.” 2. According to Kathryn Hatter Aside from the technologies that really helped in making our teenagers become lazy‚ there are also other reasons. From Kathryn Hatter’s article‚ lack of motivation is one of the reasons why. “While some

Gay/Lesbian Families Adoption is an extremely sensitive subject‚(insert dash) especially for individuals who are Gay or Lesbian. There is much controversy on the topic. There are a variety of ways to which it isn’t possible for a couple to adopt. Infertility is becoming a greater problem in our time. In Gerald P. Mallon’s article‚ “Assessing Lesbian and Gay Prospective Foster and Adoptive Families: A Focus on the Home Study Process‚” in 2007. He introduces a few different ways gay men and lesbian

Diola; ladyjewellyndiola@yahoo.com Abstract Synthesis of 3‚4-dihydro-3-(p-methylphenyl)-1‚2-(2h)-benzoxazine involves the nucleophillic addition of the 1 °amine group upon the carbonyly group of the salicylaldehyde‚ the reduction of imine to amine and the addition of paraformaldehyde to proceed ring closure. The experiment prepared the product through Mannich reaction‚ a multicomponent condensation synthesis between ketone‚ aldehydes‚ enols and amines. Biosynthesis of benzoaxazines

Lab 3: Grignard Synthesis Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product.

Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic

living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding‚ through four nitrogen bases (adenine

individuals unskilled at chemistry they could result in serious bodily harm. MDMA ("Ecstasy") is a semi-synthetic compound which can be made relatively easily from available precursors. Synthesis instructions exist which can be followed by an amateur with very little knowledge of chemistry. However‚ people with less than 2 years of college chemistry experience would probably not be capable of sucessfully synthesizing MDMA‚ and would either botch it in the best case or kill themselves in the worst case
