Aspirin Aspirin is a salicylate‚ also known as a non steroidal anti-inflammatory drug (NSAID). It is the generic name of acetylsalicylic acid and is used clinically to treat fever‚ pain and inflammation as it works by preventing the formation of prostaglandin. Prostaglandin is the active agent that is responsible for the sensitisation at the nerve endings. It can be administered orally‚ rectally or by intravenous route.

The Melting Pot Is The United States of America the “melting pot” of the world? A melting pot is “a place where races‚ theories‚ etc.‚ are mixed.” (The Oxford Dictionary) Many immigrants come to the United States for the same basic reason: A better way of life. These same immigrants envision their dreams of success‚ freedom and happiness coming true. Without different cultures coming together learning from one another‚ many of today’s modern marvels would not exist. A good example of this is

October 17 & October 24‚ 2012 How is Aspirin Made? This lab is about synthesizing aspirin using a hotplate to heat the reaction. It involved vacuum filtration‚ recrystallization‚ and comparing the properties of aspirin with salicylic aspirin. The first thing we did in this lab was make a hot-water bath by putting a beaker with water on a hot plate. After measuring out 2.1 grams of salicylic acid and 3 ml of acetic anhydride‚ we mixed the two together‚ along with 3 drops of sulfuric acid. We

Darnell Shaw Lab Extra Credit Hippocrates of Cas (460-377 B.C.)‚ The Healer‚ noted that chewing leaves of willow (Salix) reduced pain‚ and he prescribed this remedy for women in labor. The Healer certainly did not discover this drug‚ which was used for centuries earlier in European folk medicine. Ancient Egyptians took an infusion of dried myrtle leaves to treat muscle pain. The myrtle leaves were also found to contain salicylic acid. Two Italians‚ Brugnatelli and Fontana‚ had in fact already

spring and summer is the principal melting energy source. Most operational procedures for snow melt prediction rely on ambient air temperature as the index of the energy available for melt. The temperature index is usually used to characterize the level of the energy balance because it is superior to other simple methods for the full energy balance at the snow surface. As long as snow remains bright‚ the sunshine bounces off and is not retained to cause any melting. Two factors other than sunshine

Determination In “The Glass Castle” we see many different possibilities pertaining to Maslow’s Hierarchy of Needs. We see the father‚ Rex and one of the daughters‚ Maureen‚ who fall victim to Maslow. Then there’s Jeanette and the mother‚ Rose Mary who have both seemed to achieve self-actualization regardless of their hardships. Traditionally‚ Maslow’s Hierarchy is thought to be achieved by working up from the bottom of the pyramid to get to the top. However‚ in “The Glass Castle” this is not particularly

This paper is a full determination for certain chemicals and their boiling points. It lists some already but given the atomic numbers of any material this project includes a conversion and calculation chart to find the freezing point of most any material. GOOD LUCK! Abstract: In this lab we determined the freezing point‚ and Kf‚ of pure 2‚4‚dichloralbenzne as well as a 2‚4‚dichloralbenzne/biphenyl solution. We used this information to determine the molar mass of an unknown (#24) by the 3rd step

IB1 Chemistry Practical #8 ANALYSIS OF ASPIRIN TABLETS For a long time the bark of the willow tree (salix alba) was used as a traditional medicine to relieve the fever symptoms of malaria. In the 1860’s chemists showed that the active ingredient in willow bark is salicylic acid (2-hydroxybenzoic acid) and by 1870 salicylic acid was in wide use as a pain killer (analgesic) and fever depressant (antipyretic). However‚ because it is a relatively strong acid‚ salicylic acid has the undesirable side effect

It should stress the information of little side effects compared to other analgesic medicine. Both the retail price and the trade price should be lower than Tylenol. Segmentation and targeting: Datril should target on aspirin users. Datril potential clients could be 1) people currently using aspirin 2) people currently
