Louis Pasteur essays

Louis Pasteur essays My report is about Louis Pasteur and about the things he invented and/or discovered. About who he is and about hes life. I am also going to talk about why the things were invented and/or discovered. Louis Pasteur was born December 27, 1822, in Dole, France. He was the son of a tanner. In 1867 Pasteur left his job of director of scientific studies to focus on his research. In1868, a brain stroke partially paralyzed Pasteur, despite his poor health, he continued his work. Pasteur died in 1895 and was buried in a tomb at Ecole Normale. Pasteur came up with numerous medications and scientific discoveries. He changed hospital practices to help prevent the spread of disease by microbes. He discovered that diluted forms of microbes could be used for immunization against more virulent forms of microbes. Pasteur find that rabies were transmitted by agents so small they could dot be seen under a microscope revealing the world of viruses. He developed a vaccine to keep dogs from getting rabies and to treat humans that get bitten by dogs with rabies. Pasteur developed pasteurization to pre vent harmful microbes perishable food products use heat to destroy microbe with out destroying food. Louis Pasteur discovered rabies on Monday January 6,1885. So that people who do get rabies can get rid of them. They wouldnt have to worry about getting sick and maybe even dieing. And they can also get rid of the rabies if the dogs get them. That way they dont give them to anything or anybody. I talked about Louis Pasteur throughout my report and about the things he invented and/or discovered. He invented the cure for rabies. He discovered rabies in the year of 1885. ...

Make the Most of Your Tactile Learning Style

Make the Most of Your Tactile Learning Style According to some educational theorists, there are as many as nine different types of intelligence and multiple styles of learning. Tactile or kinesthetic learners are those who learn through experiencing and doing things. How Tactile Learners Learn Tactile learners like to experience the world and act out events. To remember a phone number, tactile learners may remember the pattern of their fingers as they  press the numbers on a phone or keypad. Tactile learners can remember complicated directions once theyve acted them out. Look over these traits to see if they sound familiar to you. You may be a tactile learner if you are someone who: Is good at sportsCan’t sit still for longIs not great at spellingDoes not have great handwritingLikes science labStudies with loud music onLikes adventure books, moviesLikes role-playingTakes breaks when studyingBuilds modelsIs involved in martial arts or danceIs fidgety during lectures Challenges for Tactile Learners Because tactile learners learn best through movement, they may become bored more quickly than other students while listening to a class lecture. They may also find it difficult to focus on long lectures, write extended essays, or read for extended periods of time. Study Tips for Tactile Learners An active study is good for every student. But it is especially important for the tactile learner to use active study strategies when preparing for a school exam. Tactile learners need to be actively involved as they receive and process new information. Kinesthetic learners can benefit from: Studying in short blocks of timeRole-playingTaking lab classesTaking field trips or visiting museumsStudying with othersUsing memory gamesUsing flashcards to memorizeUsing a smart pen for taking notes. A smartpen records audio content that takes place while the student is taking notes. That means that students can go back to review class notes and listen to any lecture that took place as the student recorded notes.Acting out the topics, stories, and subjects they study. For example, activities like reacting to the past enable students to immerse themselves in the topics and experience subjects they study.   Tactile learners may choose to use the Journey Method for memorizing new information (mentally placing concepts in a location). Learning games and group activities are good tactics for the tactile learner. The more active this student can be during study time, the more information that study is likely to retain. When preparing for an exam of any type, the tactile learner should practice writing a test essay (make up your own essay questions). Write the first essay using the textbook as a guide, then practice the essay several times in preparation for test day. Opportunities for Tactile Learners Certain types of classes are likely to appeal to tactile learners. For example, tactile learners will thrive in the sciences that include a lab experience. They are also likely to do well in classes that combine hands-on and conceptual learning such as: Culinary artsHome economicsEarly childhood developmentTheater or other performing artsVisual arts (sculpture, for example)Engineering If you are a tactile learner in a high school or college setting, consider choosing electives or a major that makes the most of your strengths.

Nanotechnology and microfabrication Essay Example | Topics and Well Written Essays - 1000 words

Nanotechnology and microfabrication - Essay Example Due to carbon’s wide applications, it is not surprising that it is also a key component in the rising field of nanotechnology. Beside its natural occurrence in the form of graphite and diamond, carbon exists in the nanostructured forms of fullerenes or buckyballs and in carbon nanotubes. The beauty of carbon nanotubes formed by carbon atoms is that they are twofold stronger than steel but weigh six times less. Carbon nanotubes are allotropes of carbon that have been first constructed by S. Iijima in 1991. These are significantly extended thin cylinders and large macromolecules of carbon with unique features in their shape, size and physical properties as well as having the highest ratio up to 28,000,000 between length and diameter (Zheng, 2004). This is larger than any other material in the world. They can be envisioned by taking a mass of graphite into consideration that is rolled into a cylinder shown as Appendix-I figure (i) on page 6. These fascinating structures have flashed world wide great excitement and appraisal during last few years. Currently a huge amount of money is being spent on these carbon nanotubes to improve the understanding of their properties. Still its physical characteristics are being discovered and controversial results are being obtained. The development and research on synthesis methods is considered as a vital step to the future outlook of carbon nanotechnolog y. The structure of a carbon nanotube can be envisioned by taking a mass of graphite into consideration that is rolled into a cylinder as shown in figure (i) on page 6. Nanotubes, on the basis of the direction of hexagons, are classified as zigzag, armchair or chiral and are shown as Appendix-I figure (ii) on page 6. There are two types of carbon nanotube i.e. single-walled nanotubes (SWNT) and multi-walled nanotubes (MWNT). Generally SWNT are composed of a diameter close to1 nanometer while the tube length that can have a length millions of times longer and are excellent

Annotated Bibliography Example Even though the article has a narrow perspective on leadership topic as a whole, its detailed focus on transformational leadership is critical in having a better understanding of this style of leadership. In this view, this article is important for the research in organizational leadership as it gives sufficient information pertaining to transformational leadership style. Emery, C. R., & Barker, K. J. (2007). THE EFFECT OF TRANSACTIONAL AND TRANSFORMATIONAL LEADERSHIP STYLES ON THE ORGANIZATIONAL COMMITMENT AND JOB SATISFACTION OF CUSTOMER CONTACT PERSONNEL. Journal of Organizational Culture, Communications & Conflict, 11(1). Emery and Barker (2007) explore the effects of transactional and transformational leadership styles on organizational commitment and job satisfaction. Starting from the definition of these two leadership styles, the article gives a stepwise comparison of the two leadership styles. Organizational commitment is depicted as a crucial aspect in enhanced performance, reduced employee turnover, and general job satisfaction as employee feel well motivated. Similarly, customers tend to be satisfied when they perceive that the leadership style in the organization pays direct attention to their needs. Therefore, apart from giving information relating to the effect of the two leadership styles, the article helps the reader understand the preferable leadership style. In this book, Kotter (2008) discusses the concepts of leadership and management in details. His primary focus is to help the readers distinguish leadership from management by radically analyzing them. Using a systematic approach, the author manages to indicate that not all managers are leaders as a significant portion of them fail to acknowledge the factor or rather attributes of a good leader.

She ran up the wooden staircase Essay Example for Free

She ran up the wooden staircase Essay It is an odd case this. Peterson had a motive I understand his mother was rich, perhaps he wanted his inheritance quickly so he could marry the girl as is good and proper. The girl has a motive Lady Peterson had a rather low opinion of her. I am rather inclined to think of Miss Smith she had opportunity, and motive. Is it a pure coincidence she came down on the same day as the lady was discovered dead? I somehow think not. It must be her that letter proves it! That is an odd occurrence. Of course, there is the possibility she forged it herself to gain sympathy, but I somehow I think not, he paused. I saw the familiar pipe slip out from underneath his cloak and into his mouth. However, supposing she did the deed, and the purpose was to marry Edward Peterson, staging a quarrel with said man seems rather pointless. It was two mornings later when I received an early morning phone call from Holmes that brought me out of my slumber. Hello? I said tentatively. Watson, we are going to visit Miss Smith, my friend said matter-of-factly, without introducing himself or apologising for waking me up what must have been five am, if not earlier. So it was that I found myself on the train to visit the woman I suspected of murder. I was sitting by the window, doing the crossword in The Times, all the while aware of Holmes watching me as a child watches the ants that scurry across the garden path. Tell me, Watson, what would you say if I told you who the murderer was, right here, right now? he asked, an amused expression on his face. You know? I cried. Then why are we visiting the young lady at this hour? No no, my dear Watson, I was merely speculating, Holmes finished, and neither of us said a word until the train reached the station that was to be our destination. Come Watson, my friend said in his usual brisk manner. We will get a horse and carriage from here to the ladys house. She is staying with a friend or so she says in her letter. A letter? I cried incredulously. She sent you a letter! Why hadnt he mentioned this before? The girl believes her life is in danger. She is frightened, understandably so. It is my job to help her, he stated matter-of-factly. Yes but- I stopped. The horse and carriage had arrived, and I followed Holmes clambering in to it. Of course, she may be mistaken, he continued, but it may prove a valuable clue. Rose Smith was staying in a small house with her friend, who was introduced to us as Helena. It was a pretty, country cottage, not the sort I would expect Miss Smith to be staying in. Im going for a walk, Helena announced shortly, as she picked up a raincoat and closed the door behind her. Good luck Rosie! So, Miss Smith, Holmes said, You wrote to me because you believe your life to be in danger. Why? Gosh, you do get to the point quickly, dont you? Miss Smith laughed nervously. Ill start from the beginning. I met Ed Mr Peterson, that is at a dance. He was there with a friend who happened to be a friend of a friend of a cousin of mine. So we were both at this party, and I must admit, it wasnt what lady Victoria would approve of. Shes dreadfully serious, you know! Very traditional. Oh shes a dear, but so interfering. Ed and I got talking and well, we fell in love. His mother threatened to disinherit him if we kept seeing each other, but then, quite out of the blue, she gives us another chance, and invites me to stay for a little while. He came to collect me from the station, and on the way back to the house, he proposed to me! Oh I was so happy, it was a dream comes true. But now it look like there wont be a wedding after all, she said, as she broke down in tears. I noticed on her forearm lay a large purple bruise as I reached my hand out to comfort her. Whats that? I asked suddenly. Oh nothing, she muttered. Let me tell you what happened when you received the letter from Edward Holmes began. So it was from him, she cried. Even as I wrote to you I hoped it was someone else. There are many names beginning with E Egbert, Emily, Ellie. Why him? I saw a sudden look come into Holmes eyes he knew whom the murderer was. I could tell by the excited glint the dark black pupils had taken on. One more thing, Miss Smith, Holmes said as he showed her the picture we had seen in the ladys room. Its Ed! she cried. Excellent! he said, as he left the room. Excellent. NOT FROM WATSONS NARRATIVE Tell me, Mr Peterson, did your mother spill her tea the day she died? Holmes asked. Why, yes, yes she did. And Rose gave her hers, I think. She doesnt like tea anyway. AFTERWARDS BY WATSON So how did you find out? I asked. I must admit, it had me fooled. Id never have guessed. Well, it was quite simple really Watson. The entire crime rotated around the stain. That one spill held the key to the entire murder. Once I knew who had spilt the cup, the whole mystery came together like a well-knitted scarf. But how? I know I must be terribly ignorant not to see, but how? You see, I know that Lady Peterson spilt the tea. Miss Smith then gave the Lady her mug, which she drank. Lady Peterson later died, and I think I can safely assume it was that mug that was poisoned. We therefore have two options. Either Miss Smith poisoned the tea or the tea was already poisoned when Miss Smith took it! You mean, Miss Smith was the intended victim! I do indeed, Holmes smiled. You see, one of the housemaids had entertained a liking for Edward Peterson for many years. She steals photos of him; she spends extra time tidying his quarters, and she is in fact, quite infatuated. So when Miss Smith appears, our admirer is jealous. Later, she hears her love proposing to this girl, and decides something must be done before her love marries this stranger. In the tea, she slips a strychnine tablet into one of the mugs. But then her plan fails. Instead of her hated rival taking the tea, her employer, the kindly woman who has the power to stop this marriage, dies. I sat in stunned silence for a few seconds, unable to speak. But why then, the flower, the letter? I asked. Our murderer has a somewhat romantic mind jealous women often do. She thinks miss smith is the perfect suspect. Miss smith, who happens to be named Rose. Hence the flower. A silly, girlish touch really. The clue does not point to Rose, but to someone who would be willing to spring the crime on her. Of course! I exclaimed. And the letter? Well that was simple, although I must admit I was nearly fooled. Who was the maid girl who served us our tea, Watson? Why, err, of course Ellie, I believe! Ellie Pierce, in fact! the genius pointed out. Our mystery EP! Brilliant, I really dont know how you do it, Holmes. Brilliant! Elementary, my dear Watson. Elementary!

Lorraine Hansberrys A Raisin In The Sun :: essays research papers

Ronils Review of A Raisin in the Sun. This is probably the first play I've ever seen that I REALLY HEATED. A Raisin in the Sun The Madison Repertory Theatre has produced many plays by African American playwrights recently, such as last year's From the Mississippi Delta, but their most recent, Lorraine Hansberry's A Raisin in the Sun is certainly one of the veryWorst. The play starts in a darkened living room. Ruth Younger wakes her family on a Friday morning. Her father-in-law has recently died, and the family is awaiting the arrival of the insurance money. Her husband, Walter, has plans to use it to buy a liquor store, but wife doesn't believe he belongs in business. Beneatha, Walter's sister daughter, hopes to use the money for her tuition for medical school. Walter's mother, Lena (Mama), plans to use the money for a house for the family. On top of all this, Ruth has discovered that she is pregnant. In an effort to find a true identity, Beneatha has shunned her mother's religious beliefs and has taken an interest in Asagai, a Nigerian student. Asagai brings her a tribal drum recording and a robe from his country. Beneatha is also being pursued by another suitor. George Murchison, a student belonging to the upper class also has an interest in her, and regards her embracement of African culture as childish. After the money arrives, Mama leaves to "take care of some business." When she returns, she announces just what it was that she did do: she has bought the family a house...in Clybourne Park, an all-white neighborhood. Mama then entrusts the rest of the money to Walter, to invest in his sister's education, and to put the rest into a savings account under his name. Walter promises his son Travis a great future, and promptly invests it in his liquor store. While packing, the family is visited by Karl Linder from the Clyborne Park Community Improvement Association, and a white man. Linder explains that the Younger family might not be welcomed in Clybourne Park, and might be better off living in a black neighborhood. "It has nothing to do with racial prejudice," he explains. To make matters worse, Bobo, Walter's friend comes to say that the third member of their team, who had been entrusted with all the money is gone. Period. In desperation, Walter calls Linder to buy the house back, but after a talk with

Elizabeth Gaskell and Industrialization Essay

Two of Elizabeth Gaskell’s novels—North and South and Mary Barton—provide a critical insight into the author’s attempt at probing the issues surrounding industrialization in Victorian England. Apart from the fact that both novels feature female characters as protagonists, they also highlight the classic struggle between rich and poor classes in the face of an emerging industrial society. Without losing track of the flow of the stories’ plots, Gaskell is able to incorporate the vital aspects of industrialization. In North and South, Elizabeth Gaskell writes about the struggles of the urban working class in industrial England, specifically in its northern regions, during the 19th century in contrast to the lifestyles of those who live in the wealthier south. Because the story is shown from the perspective of the heroine, Margaret Hale, Gaskell is able to display the other side of the stereotypes attributed to women during the 19th century. For the most part, women at that time were barely able to face their personal circumstances and address them on their own. Margaret Hale, however, defies the notion that women largely depend on men just to live. She initially resists that belief by rejecting romantic proposals—a move that shows how she is in control of her life—and displays it at its highest when she throws her arms around John Thornton in an effort to protect him from the angry mob. The latter indicates that it is not always women who seek the protection of men because women can also protect men even at the expense of such women. As Patsy Stoneman indicates in her book Elizabeth Gaskell, â€Å"[Margaret Hale] confronts the fact that men of all classes are governed, in the public sphere, by a masculine code,† a code that effectively prevents the characteristic of tenderness attributed to females (Stoneman, p. 86). Margaret’s willingness to protect Thornton does not only imbibe the thought that women are tender and should not be harmed. It also presents the idea that women—especially those who are considered outsiders to industrial areas such as Milton—can also learn to sympathize with the people who are working under poverty. The incident in the story where the workers were in a strike against Thornton, the local mill owner, also underlines the idea that an outsider can relate to the woes and conditions of the workers more than those who are directly involved in the industrial system. Another interesting aspect of Gaskell’s thematic exploration of industrialization in North and South is how she was able to reunite, in a manner of speaking, the classes considered as polar opposites. As Dorice Williams Elliott observes in her article: â€Å"the novel bases its case for women’s mediation between classes on an analogy between marriage and class cooperation† (Elliott, p. 25). The presence of the outsider, Margaret, in the industrial town makes it possible for the marriage between the classes to commence. Margaret became no less than a person who paved the way for the better understanding between the rich and poor divide although her presence alone did not entirely dissolve the prevalent disparity. Elliott’s observation that Margaret’s mediation led to class cooperation simply reaffirms the idea that ‘class cooperation† in itself still presumes differences between social classes. In Mary Barton, the disparities between the rich and the poor classes take the shape of the story of a father who seeks to protect his daughter from becoming a fallen woman. Like Margaret Hale in North and South, the story revolves around the life and struggles of Mary Barton in Victorian England. John Barton, Mary’s father, is a millworker who lost most of the members of his family except Mary. One interesting part of the story is when John shot Henry Carson, the son of a rich mill owner. Being someone who deeply questions the wealth disparities between rich and poor—largely because he was â€Å"chairman at many a Trade’s Union meeting; a friend of delegates,† someone who was â€Å"ambitious of being a delegate himself† and a â€Å"Chartist† who was â€Å"ready to do anything for his order† (Gaskell, p. 25)—John’s murder of Henry symbolizes how the members of the poor class sometimes grow desperate. The story is ingenious in the sense that it perfectly subsumes the issues surrounding industrialization in Victorian England into the tale of a woman’s quest for love. Mary Barton is a classic example of how Gaskell effectively writes about the problems caused by industrialization in Victorian England without losing sight of the story’s plot. Despite the debates as to whether Gaskell’s novels genuinely reflect the true nature of the Victorian English society during the onset of the industrial period, it should be reminded that what her novels do is to give a fictional account of the problems people face when dealing with people from another social class. Susan Morgan writes that â€Å"the criterion of likelihood is an inappropriate approach to Gaskell’s work† (Morgan, p. 44). For example, â€Å"it may have well been unlikely in Manchester for relations between worker and employer to find solutions through individual friendships† (Morgan, p. 44). Whatever reasons there may be as to why Gaskell wrote as she did, it is enough to note that North and South and Mary Barton capture the struggles of fictional characters in the face of industrialization. The novels may be fiction at best, yet the circumstance they suggests—the epic divide between rich and poor—remains as real today as it once was.
