Free Essays on Louis Pasteur

Louis Pasteur Louis Pasteur was an example of a truly gifted person who made many wildly diverse discoveries in many different areas of science. He was a world-renowned French chemist and biologist whose work covered the way for branches of science and medicine such as stereochemistry, microbiology, virology, immunology, and molecular biology. He also proved the germ theory of disease, invented the process of pasteurization, fermentation, and developed vaccines for many diseases, including rabies. Pasteur was born on December 27, 1822 in Dole, France, and grew up in the small town of Arbois. As a young boy, Pasteur showed no particular interest in science. His talents were mainly drawing and painting. During his youth, he developed an ambition to become a teacher. During his studies to become a teacher, a chemistry professor, Monsieur Jean-Baptist Dumas, fascinated him. He decided that he wanted to learn to teach chemistry and physics, just like his favorite professor. (Debre, P. Louis Pasteur.) In 1847 he earned a doctorate at the Ecole Normale in Paris, with a focus on both physics and chemistry. Becoming an assistant to one of his teachers, he began research that led to a significant discovery. He found that a beam of polarized light was rotated to either the right or the left as it passed through a pure solution of naturally produced organic nutrients, whereas when polarized light was passed through a solution of artificially synthesized organic nutrients, no rotation took place. If bacteria or other microorganisms were placed in the latter solution, then after a while it would also rotate light to the right or left. From this, he concluded that organic molecules exist in one of two forms, â€Å"left-handed† or â€Å"right-handed† forms. After spending several years researching and teaching at Dijon and Strasbourg, Pasteur moved in 1854 to the University of Lille, where he became the professor of chemistry and dean ... Free Essays on Louis Pasteur Free Essays on Louis Pasteur Louis Pasteur: Greatest Achievements Louis Pasteur was one of the most important scientists of our time. The foundation of our knowledge about health and disease comes from the discoveries of this one man. He made many discoveries and solutions for problems of the every day life that are still in effect today. Pasteur was born on December 27, 1822 in a little town called Dà ´le in the foothills of the Jura Mountains of eastern France. When he was five years old his family moved to Arbois where he grew up with his father, mother, and three sisters. While attending primary school Pasteur was only an average student. Some considered him to be slow because he worked so hard on an exercise problem to make sure that he had the right answer. While in high school Monsieur Romanet, Pasteur’s principal, became interested in Pasteur and began to help him with his studies. With this encouragement Pasteur became a very good student. The principal suggested that he aim to attend Ecole Normale in Paris where he could become a professor at one of the great universities, however his father felt that this was far-fetched and preferred that Pasteur attend a more local school (Burton, 5-7). Although his father had other plans for him, Pasteur had the opportunity to attend a preparatory school in Paris before going on to Ecole Normale, however when he got to Paris he became very homesick and his father soon arrived to take him home. After returning to Arbois Pasteur attended a local school named Besancon where he worked very hard and became one of the top students in his class. In 1842 Pasteur passed the admission tests to attend Ecole Normale however he was rated fifteenth of twenty-two candidates and this was not good enough to satisfy him. He continued to study and finally in 1843 Pasteur sailed through his admission tests and was awarded fourth place among the other candidates (Burton, 7-11). Although Pasteur is sometimes considered to be th... Free Essays on Louis Pasteur LOUIS PASTEUR There is a time in every man's life when he looks to his God, when he looks at his life, when he wonders how he will be remembered. It can happen with age or with tragedy or closeness of death. I am lying here at age 45, not able to feel my left side. Not knowing if this stroke that has befallen me will end my life before the mysteries that I have unlocked can be resolved. I have asked God throughout my life to be able to "...bring a little stone to the frail and ill assured edifice of our knowledge of those deep mysteries of Life and Death where all our intellects have so lamentably failed." (Vallery-Radot, 88) Death is more familiar to me than I care to think... three of my daughters.. .my father.." I have been thinking all day of the marks of affection I have had from him. For thirty years I had been in his constant care, I owe everything to him. When I was young he kept me from bad company and instilled into me the habit of working and the most loyal and best filled life. He was far above his position (tanner) both in mind and in character. The touching part of his affection for me is that it was never mixed with ambition...and yet, I am sure that some of the success in my scientific career must have filled him with joy and pride..."(Vallery-Radot, 119) Science...it is my life..it has brought me a deepness of pleasure that I have always known yet never realized. I remember when I was working on the tartrates, tartaric acid and racemic acid or paratartrate. Tartaric acid was known to rotate light to the right, whereas paratartrate, odly enough, did not affect light in the least. "The fortunate idea came to me to orient my crystals with reference to a plane perpendicular to the observer, and then I noticed that the confused mass of crystals of paratartrate could be divided into two groups according to the orientation of their facets of symmetry. In one group, the facet of symmetry nearer my body was inclined to my r...

JetBlue - Case Study Coursework Example | Topics and Well Written Essays - 4000 words

JetBlue - Case Study - Coursework Example To analyze the strength and stability of the sales revenue earned by the company over the years, ratio analysis will be useful. Thus in this case study ratio analysis is applied for evaluating the increase in net revenue in relation to increased operating expenses. â€Å"Profitability reflects the final result of business operations.† (Chandra, 77). In order to identify the profitability of a company, gross profit ratio analysis and net profit ratio analysis have to be undertaken. The trend in the gross profit ratio of the company over the years shows that there is an increase in its gross profit. From a loss of about $21188000 in the starting year of 2000, JetBlue earned a gross profit rate of 8.366 % in the next year itself. This shows that the company has a high potential to overcome its financial challenges. In the year 2002, the gross profit ratio had increased to 16.528%. The half year performance of JetBlue shows a gross profit ratio of 18.07%. But after that in the next half year there occurred a slight decline in gross profit ratio can be seen. It is 17.32 %. The gross profit rate graph of the company shows signs of significant increase. Net profit ratio analysis of JetBlue further shows that the operating performance is considerably improving. In the initial year, the company has incurred operating loss of $ 21330000. In the next year, company earned net profit of $ 38537000. The net profit ratio in the year2001 is 12.027%. In 2002, it decreased to 8.64%. During the first half of 2003, it again increased to 9.76 % and in the next half year it further increased to 11.977%. Thus, the net profit ratio of JetBlue is not found to be stable in nature. The ratio analysis on sales revenue shows that there is fluctuation in the net profit of the company over the past three years. This is due to higher operating costs resulting from increased interest expenses and increased taxation charges. â€Å"Financial risk can be measured from operating

Distributive Justice ( healthcare ethics) Case Study

Distributive Justice ( healthcare ethics) - Case Study Example So, finally, the Krampitz family is absolved, their doctor is absolved. Who, then, is guilty for the lapse There is also the uneasy question doing its round in the mind - what were all the healthcare organizations doing while the Krampitz were busy sending out ads with their request On going through the guiding principles declared by some healthcare organizations one is led to except better vigilance from them. To quote a few, these are the quotes expressed by some of them: "I envision The Center as a guardian for the voiceless and as an educator. I fervently believe that although we may never evolve into a 'cash rich' organization, we must always remain rich in voice." (http://www.healthcare-ethics.org)1 "Hospitals such as UCLA Medical Center that develop and provide cutting edge medicine need a mechanism to balance complicated medical and ethical issues" said Dr. Neil Wenger, the center's director and a UCLA professor of medicine and health services research. "Academic medical centers often confront complex life and death questions. We must help patients and their families through the process of negotiating difficult ethical decisions. This center builds on our ethics consultation service by promulgating innovative research, providing opportunities for creative policy development and enhancing the knowledge and activities of doctors, nurses, social workers, chaplains and medical students in addressing ethical issues at the patients' bedside." (http://www.healthcare.ucla.edu)2 Now, keeping in mind the Todd Krampitz incidence, and the well-meaning claims put up by different healthcare organizations, it is very difficult to be judgmental either way because it involves ethics on the one hand, and the precious life of a patient, on the other. At the outset, it must be clarified that the issue requires dispassionate deliberations. Todd Krampitz's life is precious to him and his family. Then there is one other patient among 17000, who is equally or more desperate for a liver transplant. Then there are ethics showing Todd Krampitz had circumvented the system for his own selfish purpose. Lack of Communication Ultimately, the whole issue boils down to one disappointing possibility. Lack of communication. Todd Krampitz did not realize the seriousness of the situation, being desperate to solve his own problem. His doctor was mostly likely unaware of the need to check up on the issues of ethics. After all, how many doctors will busy themselves on questions of ethics in so serious a situation as a failed liver. Will a lawyer go checking up with every accused to see how innocent he is before taking up the most deserving case Who should be blamed If anyone is to blame, then it is the system. The system has not been created which

The objectives of the lesson plan include focusing on the values of responsibility, care, compassion, respect and sustainability. The key learning areas here include art, society & environment and science. The first activity includes thinking about water in a session. Students can  think and generate questions on the topic such as: What is water? Where does it come from? How it is stored and used? Is there enough availability of water for the humanity? Questions like these can certainly generate a lot of curiosity among children and help them in knowing its value and appropriate use. The thinking session will be followed by questions and queries discussed by students among themselves. They will be asked to write their ideas on the board. This activity asks students to identify ways of using water resources. Several pictures and short movies are shown to students and questions are asked based on water usage, responsible usage and conservation of water. Students are to visit the school campus and ask to note down the ways of water usage on a sheet of paper. Students will come to know the overall water usage from different sources such as drink taps, kitchen, gardening water, staff rooms and toilets. After this, they will categorize all what they have seen inside the school campus. The curriculum will move ahead with two activities covered in the
