Aspirin essays

Aspirin essays Analgesics are compounds used to reduce pain, antipyretics are compounds used to reduce fever. One popular drug that does both is aspirin. Salicylic acid is reacted with acetic anhydride with the use of heat and sulfuric acid, which acts as a catalyst, to produce acetylsalicylic acid or commonly known as aspirin. This process is known as esterification. In the experiment, 2.0293 g of salicylic acid is used to react with 4.00 ml of acetic anhydride to produce 0.3565 g of acetylsalicylic acid giving rise to a 13.45 % yield. Salicylic acid is a simple aromatic carboxylic acid that became a key component of medical treatment throughout history, dating back to the Greeks (400 BC) and their use of willow tree bark. It was found in 1827 that the active agent in willow bark is an aromatic compound called salicin, which could be converted by reaction with water into salicyl alcohol and then oxidized to give salicylic acid. Felix Hoffman, working for Friedrich Baeyer and Company in 1883, acetylated salicylic acid and reduced the irritating side effects of salicylic acid in the mucous membrane of the stomach and made one of history's most popular drugs commonly referred to as aspirin (acetylsalicylic acid). Aspirin proved to be more effective in relieving pain and inflammation of rheumatoid arthritis. In a search for even more effective and less irritating analgesics and anti-inflammatory drugs, the Boots Pure Drug Company in England discovered ibuprofen. Soon thereafter, Syntex Corporation in US developed naproxen and Rhne-Poulenc in France developed ketoprofen. In the 1960s, it was discovered that aspirin acts as by inhibiting cyclooxygenase (COX), a key enzyme in the conversion of arachidonic acid to prostaglandins. The acetyl group of aspirin is transferrable to enzymes such as prostaglandin synthase. Acetylation of prostaglandin synthase inhibits its cyclooxygenase acti ...

Career Choice Project †Information Systems Current Issues Essay (300 Level Course)

Career Choice Project – Information Systems Current Issues Essay (300 Level Course) Free Online Research Papers Career Choice Project Information Systems Current Issues Essay (300 Level Course) After completing the Career Choice application provided by the Internship and Career Center, I was given many choices of jobs that would suite to my lifestyle as well as was able to choose jobs and research what I was interested in. Once Career Choice was completed, and it provided jobs that â€Å"suite to my lifestyle†, I disagreed with what was originally given. Once slowly working through it, and more data was taken from me, information on what jobs I would be interested in matched much more consistently to my ideas. The three jobs I found to most suite what I am interested in are Computer Network Telecommunications Technician, Computer Network Systems Administrator, and Engineer, Computer Systems. A Computer Network Telecommunication Technician (CNTT) includes the assistance to a network administrator dealing with hardware, software, or infrastructure to an information system. As this career does not require a bachelor’s degree, it would be just a start to moving up the chain of command. As the skills needed in this job are Technical, Computer literacy, and diagnosing I believe I am well prepared to do this job. As the work conditions are nearly equal to an eight to five job, not many overtime hours, but this comes with the basic salary of 30 – 35 thousand dollars per year. A Computer Network Systems Administrator (CNSA) is the knowledge to know what and when to install in an information system, as well as the capability to install and maintain. This career requires a bachelor’s degree in some type of information systems degree. Skills needed in this occupation would include Information Handling, Computer Literacy, and diagnosing. These three jobs also are included in what I believe I am capable of. As this position is a bit more time consuming, as well as the knowledge needed to take this position is more than the previous, the pay is higher. The salary for this occupation is 35 to 42 thousand a year. An Engineer of Computer Systems also known as a Systems Analyst is the occupation I am aiming for as a lifetime career. In this career, you would be in charge of handling the information data needs of users, inside and outside of your company. This position in today’s economy is growing rapidly. According to Career Choice, it is neither as high paying, nor as in demand as it really is. I am currently enrolled in a class on this subject of the information systems market. This is a very interesting subject, learning how to design and put in place everything from business processes to new technology. As this job is very much in demand in today’s economy, it is also not an easy one. Once the skill sets used in this occupation is part of my skill set, which I plan to retrieve from the first two previously described occupations. This occupation according to Career Choice requires knowledge in number computing, technical, computer literacy, and diagnosing. Each of the se skills are definitely needed, yet only real world experience can get you the skills needed to complete this occupation. The CNTT position as well as the CNSA position are very similar, and are very close in the chain of command, they both are jobs I consider to have at some point before I attempt at an Systems Analyst position. I do not believe I can fulfill my duties needed to be a Systems Analyst without the real world experience first. As I have been associated with the Information Systems world for years, I believe the base salaries given by Career Choice are low balled, and are much higher, especially with information systems degree. As the skill sets between the first two are similar, they are both similar to the third occupation. Luckily Career Choice came to the same conclusions of what I wanted to do with my life.

Learning Style Inventory Essay Example | Topics and Well Written Essays - 500 words

Learning Style Inventory - Essay Example Sometimes these questions seemed obvious or sometimes they were questions that begged for them to go deeper into the subject matter. If I was asking obvious questions I was asking because I needed clarification to make sure I was on the same page as the teacher. I am not a person that is quick to respond when there is a problem. The explanation of solitary learning style says that these people have a tendency to withdraw while they are solving a problem rather than talk to someone. This is the type of person I am which drives some of my friends crazy. I just like to think about things before I act on them. The classes I like most are those that allow me to do my own work in my own style. I do not like classes that have a set patter of things that have to be done and that expect you just to do the work without question. I like questioning and I learn more when the professors are patient and answer what I am asking. Many of my classes fit my learning style but to pick one it would have to be an English class that I had a couple of semesters ago. The teacher made English interesting because we were given a choice of projects around a theme. As an example, we were supposed to go out and look at a couple of stores and decide what they were "really" selling. Once we did this we were to write up a compare and contrast paper. The teacher was outgoing and during class time he had us reading very interesting short stories and commenting on them. His techniques matched my learning style because we were able to express ourselves in writing and he did not press those who did not talk in class. I t hought he was a very interesting person and I enjoyed his class very much. I found it interesting that security guards were one of the "common pursuits" that this learning style inventory suggested. I can see how it might be a profession where you would work by yourself but it still seems that you would be working around people and it would not be as solitary
