August Ferdinand Mobius Essays - Number Theorists,

August Ferdinand Mobius August Ferdinand M?bius was born on November 17, 1790 in Schulpforta, Germany. (Then called Saxony.) He was the only child of Johann Heinrich Mobius, a dancing teacher. She was related to the famous Martin Luther, the man responsible for writing the document known as the 96 Thesis. M?bius himself was home schooled until he was thirteen. Showing an avid interest in mathematics, he went to college in Schulpforta, Germany in 1803. When M?bius graduated from college in 1809 he became a student at the university of Leipzig. Here he started to study law against the will of his family. However, halfway through his first year he realized that law did not fit his interests. He then switched to the study of mathematics, physics, and astronomy. During his time in college, some well-known mathematicians and astronomers influenced M?bius. It is said that his greatest influence was that of Karl Mollweide, his astronomy teacher. Mollweide is known for the trigonometric relations he discovered in 1807. M?bius then went to G?ttingen, Germany in 1813. Here he studied under Carl Friedrich Gauss. Gauss, like Mollweide, was also an astronomer. However, Gauss' main interests were mathematical. From G?ttingen M?bius went to Halle and studied under Johann Pfaff, Gauss' teacher. Pfaff taught him mainly mathematics. By the end of his studies, M?bius had established firm roots in both mathematics and astronomy. In 1816, M?bius was appointed to the chair of astronomy at Leipzig. He hoped to soon become a full professor. However, his hopes were abolished when it became clear that M?bius' ability to give an interesting lecture was not quite up to par. In fact, he had to advertise his lectures as being free just to get people to come to them. He was, however, offered other jobs as a proffessor in both mathematics and astronomy at other schools. He turned these jobs down due to his loyalty to Leipzig. In 1844, Mobius was offered professorship at the University of Jena. Seeing how they might lose Mobius, Leipzig granted him full professorship. Mobius was also an observer at the observatory at leipzig. He was also involved in the reconstruction of the observatory. He was supervisor of this project. In 1820 he married and would later have one daughter and two sons. In 1848 he became director of the observatory. On september 26, 1868, mobius died. One of the great mathematicians had passed. M?bius made many contributions to the world of mathematics. The M?bius strip, M?bius net, M?bius function, and Mobius inversion formula. He also wrote a paper entitled Uber eine besondere Art von Umkehrung der Reihen, which introduced the M?bius function. M?bius also focused on analytical geometry and was considered a pioneer in topology. He also wrote important papers contributing to theoretical astronomy. These papers included The Principles of Astronomy and The Elements of Celestrial Mechanics. M?bius is best known for his work in the area of topology. Topology can be divided into three main areas: point set topology, algebraic topology, and differrential topology. The first studies in the area of topology are acctually credited to Euclid, but M?bius did some major pioneering action also. His most famous topological discovery is the mobius stip. Have you ever wondered what that odd-looking shape on the bottom of recycleable products is? Probably not, why would you. But in case you have, it is a M?bius strip. The strip is a one sided band and apparently has no beginning or end. Thus it efficiently represents the recycling program. What is so special about this strip? First, it is one of the few one sided surfaces known to man. One can take a marker, start coloring anywhere on the strip, and color every visible part without lifting the marker. Second, one can make such a fascinating object anytime, anywhere. Simply take a long strip of paper, turn it 180 degrees, and attach the ends. It is that simple. The M?bius strip is just one of many important contributions made by M?bius to the math world. Without these contributions, we would miss out on important and fascinating information in both the areas of mathematics and astronomy. M?bius was truly one of history's greatest mathematicians Bibliography Bibliography http://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Mobius.html http://www.theriver.com/mobiusjewelry/tms.html wysiwyg://19/http://www.infoplease.com/ce6/people/A0833513.html Mathematics

Y2k Bug Essays - Calendars, Software Bugs, COBOL, Hazards

Y2k Bug Essays - Calendars, Software Bugs, COBOL, Hazards Y2k Bug David Eggleston Review of Literature 2/24/99 Teri Ferguson Y2K Bug The turn of the century is rapidly approaching. This should be a time of high hopes for the future; the United States has advanced in all sorts of technology. The United States has advanced a great deal with computers, which are able to automate many difficult jobs, calculate extravagant equations, and make life easier for most people. The computer is an amazing tool allowing the United States to excel in the world. But, computers can also be the loadstone of the United States in the year 2000. The computer bug commonly known as Y2K can cause this. Y2K will cause a computers date registry to read 00 in which the computer will interpret 1900. Many people have their own opinions about how this will effect the United States and to what degree it will be effected, if the United States will be effected at all. A writer for Time Magazine states that there are wide ranges of people that are being effected in different ways by the Y2K problem. The author describes how many people are preparing for the worst and that some of those people believe that the Biblical Armageddon will arrive in the year 2000. It was stated that the Y2K problem is just another thing to keep people entertained. This was described by how the movie industry moved from spy movies such as James Bond at the end of the cold war to more sci-fi movies such as Godzilla because there was no real world problem. The purpose of this article is to simply point out that there is an actual problem with the Y2K phenomenon in order to make people aware that there are dangers even if it is just in the form of doomsayers. These points of the author are strong enough and realistic enough to make the problem known to the people but does not display any idea one way or the other. A marketing organization known as Arial Marketing posted a contingency plan on the internet that gives a view that there is going to be a strong enough problem with Y2K that one must prepare for it. This argument is supported by a few quotes from officials and high-ranking people in their respective fields. Arial Marketing made this posting slanting toward the fact that there will definitely be a problem with Y2K. Arial Marketing has even posted bad and a worst case preparation table. The purpose of this site is to tell people that their will be a Y2K problem and that in order to help people prepare for a situation Eggleston 2 two. This opinion is a strong one that is well presented and cautious with the quotes from many people backing it up. In The Year 2000 Problem: The Year the Earth Stands Still Written by a one Gary North, Gary North clearly argues his own opinion about the Y2K problem. He really does not support his case by any facts other than his strong determination to make sure that everyone knows his point of view. The point of view that he tends to support is one of terrible visions of the absolute worst case scenario of the Y2K problem. He does not have any other kind of opinion of anything less and is quite sure of the idea that the world will crash because of the Y2K problem. The purpose of this article is to display Gary Norths opinion of the Y2K problem in order to get people to prepare for the worst. The argument that Gary North has presented is a weak one for he has only state opinionated facts and has not supported this argument with any hard evidence. In just under a year the year 2000 will arrive with many hopes but it will also arrive with a Y2K bug. This bug will definitely effect some things, and maybe effect major things. The only thing that the people can do is simply prepare for the worst and hope for the best. Many organizations and even the government of the United States are working and hacking at this problem. Many organizations are making headway and will be ready to great the new millennium; others will most

'Module nursing vs centralized nursing station. Meeting the patients Research Paper

'Module nursing vs centralized nursing station. Meeting the patients needs - Research Paper Example However, on a personal basis I personally think this field has far more pros and they more then just outweigh the cons of being a part of this profession. The most positive point about being in this profession is that it gives you the power to make a positive difference in the life of the patients that you supervise. Many a times there are patients who cant even move on their own or are too lonely to discuss anything. In such times, being a nurse not only gives you the power to take care of such a patient, but it also gives you immense satisfaction to see the patient is recovering due to your efforts. This satisfaction that is derived from nursing is one of the biggest pros of this profession (American Nursing Association, 2010). Yet another factor which makes professional nursing practice so attractive is the amount of compensation it pays off. Professional nursing is one of the most well paid professions in the United States ; it allows you to make sufficient money to allow you to live a tension and trouble free life. Add to that the added advantage of having a lot of options to work as a nurse. There are many places which demand nurses but some of the most major ones include clinics, hospitals, old homes, long terms care houses and institutions which carry out clinical trial studies (Parker & Smith, 2010). There are also some legal implications which need to be followed in the field or professional nursing. To start off, the need for having a nursing license is a prerequisite for anyone wanting to perform duties as a nurse. After that there are laws designed by the parliament which need to be followed by nursing professionals and complied with. Examples of such laws include The Nurse Practice Acts and the federal statute called the ANA. The Nurse Practice Acts was designed to define the limitations of nursing practice in each state of America. Similarly, there are many other legal commandments which

Netflixs "recommender system" is a software program that is designed to learn about users by gathering data about them and drawing conclusions. â€Å"Machine learning† employs Artificial intelligence to recognize the needs of customers that uses the services of a particular company (Newitz, 2009). Computers can now supply the information that was used to be provided by individuals. Artificial Intelligence is the pillar behind Maps, Siri, and Passbook; gadgets are now able to do great things without help from users (Jackson, 2012). Rather than requesting users to rate products on a five-star scale, Netflix’s recommendation systems need to ask them to evaluate products in pairs; it will offer a correct representation of preferences of consumers. Besides recommending movies, Netflix needs to diversify and support music and games. Music and games are lucrative areas that will benefit the company. Users should be afforded an opportunity to offer feedback on how to improve the recommendation system. Netflix can offer a platform where users can give feedback on the effectiveness of the system. The three changes must be included in the system as part of the platform. Jackson, E. (2012). Whats Going To Be Apples Next Killer Product? Not a New iPhone- Artificial Intelligence.

Toyota Case Study Example | Topics and Well Written Essays - 750 words

Toyota - Case Study Example The instability serves to make fuel efficiency a more significant decision factor for vehicle consumers, increasing the desirability of the plug in hybrid. Certain consumers may see purchasing a plug in hybrid as a move that reduces dependence on foreign oil and one that serves to bolster US independence while reducing the bargaining power in adversarial governments. The entry level and middle level market segments are very sensitive to price and vehicle durability. Toyota has been able to translate its cost advantage into vehicles with higher, more attractive content and longer life than GM. He further adds that Toyota's Camry and Corolla, and derivatives of those cars have been able to dominate their market spaces they set the standard others must follow and they establish the price thresholds. Professor Peter Morici, School of Business at the University of Maryland and former Chief Economist at the US International Trade Commission remarks that Toyota enjoys much lower labor costs in the US and benefits from an undervalued yen for cars made in Japan. In the US, this comes to about $2500 per vehicle (Rossiter, 1998). In 2008 and 2009, a series of shocking economic events hit the world and Toyota. Toyota had been sprinting toward Vision 2010 of 15% market share, adding new products, building plants, deploying trainers from Japan, and focusing o n how to feed growth. To add insult to injury, the Japanese yen strengthened by 15% from July to December of 2008, and so every car shipped from Japan to the US cost 15% more. Ultimately, this led to the first loss in over 50 years of over $5 bn (Toyota Motor Corporation, 1997) Social Factors Also, Toyota has to overcome a string of problems. They include: ensuring quality and managing a sprawling network of manufacturing and sales. In spite of them Toyota plans to set-up its plants in the US, where it has to deal with labor-related issues, which its rivals are facing (Yadin, 1994). The American patriotic feeling may put the Japanese company into troubles. The US native slogan 'Wake Up America and Buy American'. Challenges the company sales in US market. Toyota, however, has taken great pains to identify itself as an American company by building plants in the south. Toyota had already earned the trust of their existing American customers (Rosen, 2000). Technological Factors Toyota is producing dominant cars from its highly efficient production system led by an efficient assembly line. It has built a reputation for technological leadership as well, most notably with the hybrid and fuel-efficient cars, such as the Corolla and Yaris and gas-electric hybrid Prius, which became big hits because of surging gas prices (The Telegraph, n. d.). Armed with cost and quality, Toyota is proud to say that its Toyota Production System (TPS)' is the key for its success. Prof. Jim Matheson of Stanford University says "The process needs low-cost and quality, and Toyota is a role model example of how to use cost and quality to get on the playing field" (Fitzgerald, 2000). Its success has been helped by

Diabetes A Major Public Health Issue Health Essay

Diabetes A Major Public Health Issue Health Essay According to current estimates about 366 million people have diabetes in 2011 all over world. It has been projected that by 2030 this will have risen to 552 million. The number of people with type 2 diabetes is increasing throughout the globe. Among them about 80% of people with diabetes live in low- and middle-income countries. The majority of people with diabetes lie in the age group of 40 to 59 years of age. Almost half of this population, 183 million people (50%) is undiagnosed. Diabetes caused 4.6 million deaths in 2011. 78,000 children develop type 1 diabetes every year. India has become the global capital for both the kinds of disease- Communicable as well as NCD or life-style diseases. There is this double burden of disease. The major diseases in the NCDs are Diabetes, CHD and Hypertension. These three diseases alone cause more than 400 deaths per million population in a year. Among them Diabetes demands the major concern because it is intricately related to the development of the two other factors (increases the risk of) CHD and Hypertension. There is also an increasing trend of obesity world-wide which also adds to the development of Diabetes as a risk factor. It is the fourth or fifth leading cause of death in the most high-income countries and it is taking the form of an epidemic in many developing as well. Diabetes has become one of the most challenging health problems of this century. There have been many studies since the last two decades which confirm that the low and middle income countries are going to face the greatest burden of this disease. The governments and public health planners of many developing countries including India still remain ignorant of this upcoming health evil. The magnitude of this disease has serious implications in terms of its economic burden in its treatment and loss in terms of wage and deteriorated quality of work by people affected by Diabetes. This can drastically influence the growth of a country especially developing countries like India. Global Prevalence of Diabetes and projection till 2030global-diabetes.png Numbers of people with diabetes (in millions) for 2000 and 2010 (top and middle values, respectively), and the percentage increase wed.png Source- Nature | Vol. 414 | 13 December 2001 | www.nature.com There have been reports of increasing cases of Myocardial Infarction even in very young patients among the Juvenile diabetes cases. It is a far more disabling than generally considered, it drastically decreases ones stamina and working capacity. As it is a multisystem disorder it influences other sensory functions as well such as Diabetic retinopathy (hampering vision), Diabetic nephropathy (causing renal disease and failure), Diabetic neuropathy (including diabetic foot) and many other complications. The presentation of classical symptoms of polydypsia, polyphagia, polyuria is not always the picture of diabetes. It is only seen in few classical cases. So, it is often diagnosed during routine test or examination done when patient had presented for some other disease or illness. The lack of awareness among people about this disease is of major concern. Due to this many cases go undetected. India has imitated the Western ways of lifestyle and hence illnesses such as obesity and diabetes are increasing day by day. In 2011, India had 62.4 million people with type 2 diabetes, compared with 50.8 million cases in 2010, according to the International Diabetes Federation (IDF) and the Madras Diabetes Research Foundation. The nationwide prevalence of diabetes in India now tops 9%, and is as high as 20% in the relatively prosperous southern cities. By 2030, the IDF predicts, India will have 100 million people with diabetes. Another matter of great concern is the fact that the onset of type 2 diabetes tends to affect people in the West in their 40s and 50s, whereas the disease strikes Indians at a much younger age. Even young people of 25 years of age are being diagnosed with the disease, a trend that threatens to seriously hamper the countrys economic development. The rise of type 2 diabetes in India was in fact foreseen by some scientists and health experts. Till1980s, the urban prevalence of diabetes was at least double the rural prevalence. But this picture of diabetes has changed significantly over time and has spread out of urban cities into the countryside and majority of rural areas. Type 2 Diabetes constitutes more than 90 % of the whole diabetes cases in any country including India. It has a wide variety of determinants and risk factors associated with it, which need to be known and focused during policy formulation to address Diabetes. Aetiological determinants and risk factors of type 2 diabetes Genetic factors Genetic markers, family history, thrifty gene(s) Demographic characteristics Sex, age, ethnicity Behavioural- and lifestyle-related risk factors Obesity (including distribution of obesity and duration) Physical inactivity Diet Stress Westernization, urbanization, modernization Metabolic determinants and intermediate risk categories of type 2 diabetes Impaired glucose tolerance Insulin resistance Pregnancy-related determinants (parity, gestational diabetes, diabetes in offspring of women with diabetes during pregnancy, intra-uterine mal or over nutrition) Source- Nature | Vol. 414 | 13 December 2001 | Www.Nature.Com Villages in wealthier southern states like Tamil Nadu and Kerala are seeing prevalence hit double digits, which is enormous. If it was confined to affluent India, you could still put a lid on it, but now its rising quickly all over the country. as per Nikhil Tandon, an endocrinologist at the All India Institute of Medical Sciences in New Delhi. There is also a considerable genetic propensity towards Diabetes in the Asian population particularly in India. india diabtes.png AIMS OBJECTIVES Diabetes has yet not been recognized in our country as a major public health issue, although the morbidity and mortality and hence economic burden and loss due to it is much higher than that caused by many other communicable or other diseases such as AIDS or STDs, for which there are well formulated programs. But there are no such programs or targeted approach to tackle this very prominent deterrent of health in our country, Diabetes. There is almost no health care accessibility and availability dedicated in this regard in public scale. They are primarily excluded from government policies and decision making process. Not much work or studies have been conducted on the prevalence of Diabetes in India, especially rural India. There is a need to assess the real magnitude of this urgent problem which demands special concern in form of targeted policies and programs and screening. The aim of my study is to highlight the immediate need of recognition of Diabetes as a major public-health co ncern and formulation of strategies, Policies and programs concerning Diabetes in India. RECOMMENDATIONS (1) Studies need to be conducted to determine the level of awareness and knowledge about diabetes at the community level in different parts of India. As we know IEC is very important for any community or mass scale program to be successful. It is also important in view of the Sickness behavior and the sick role played by the individuals. Creating awareness among the people will make them come up for the screening and a better turn up for treatment in early stage which will significantly reduce the loss due to the disease to the person and state as a whole. (2) More studies and research required to identify the risk factors for diabetes, the relationship between anthropometric measures and diabetes risk and estimate the burden of diabetes in this rural Indian population with an objective to identify target areas for future healthcare planning. (3) Screening programs need to be formulated in the mass scale and many rounds of such screening will be required to assess the real magnitude of the problem in Indian population, so that, resources are used accordingly for planning of policies and programs. These data will be extremely important for planning the public health policies especially the envisaged National Diabetic Control Program. (4) Tracing the exact pattern of the disease in the population and its demographic pattern is essential. Some of the recent studies have identified increasing cases of juvenile diabetes and there is detection of more and more cases in the lower marginalized and poorer section of population (Diabetes was once believed to be disease of elites, those of the rich sections of population associated with over eating, obesity etc). Now the picture of disease is changing which needs to be traced and addressed in the following policies for diabetes control and prevention. Research should also be directed in the direction to identify the most appropriate test for screening purpose, as the results depend on the test employed to a significant degree, especially when employed for mass screening. (5) Clear cut policy outlines to tackle with the complications of Diabetes- The complications due to Diabetes can be even more disabling and in some cases even fatal. So it is very important to make clear cut policy outlines to tackle with the complications of Diabetes and its prevention. Measures should aim at intensive control of blood glucose to prevent the retinal, renal and neuropathic complications of diabetes. There is a concealed burden of Impaired Glucose Tolerance. The possibility of preventing type 2 diabetes by interventions that affect the lifestyles of subjects at high risk for the disease have focused on people with impaired glucose tolerance (IGT). It affects at least 200 million people worldwide. Approximately 40% of subjects progress to diabetes over 5-10 years, but some revert to normal or remain IGT. So, it is very essential to take this group of individuals into consideration. (6) Formation of a separate body under Ministry of Health and Family Welfare as Diabetes Control Organization or so to tackle with Diabetes in an integrated and comprehensive way throughout the country. Formulation of Control and Prevention Programs to be implemented in each state. Prior to this there should be formation of an Expert group to assess the actual prevalence and exact demographic characteristics of Diabetes in different regions of India. (7) Reinforcing legislative changes such as increased taxation of certain unhealthy foods to promote healthy diet. Although it is difficult but such steps may help to a great extent. CONCLUSION A much more integrated approach is needed to have a significant impact on the diabetes epidemic in India. Type 2 diabetes is not merely a disease but reflection of a much bigger problem, that is, the effect of environmental and lifestyle changes on human health. We need well integrated policies for education of the mass through IEC. The major proportion of Diabetes cases in India is Type-2 which is preventable. It is a huge threat to public health and in absence of interventions there would be great loss. Thus prevention of diabetes and its micro- and macro-vascular complications should be an essential component of future public health strategies for all nations. An essential and immediate need is the formation of multidisciplinary national encompassing all parties that can help address and control the underlying socioeconomic causes that have led to the diabetes epidemic. ANNEXURE Recent studies have highlighted the potential for intervention in IGT subjects to reduce progression to type 2 diabetes. One such study is the recently completed Diabetes Prevention Program in the United States. Diabetes education is necessary to control Diabetes. It includes diabetes self-management education (DSME) and diabetes self-management training (DSMT). It helps people to modify their behavior and hence mange the disease. Healthy People 2010 objective regarding diabetes education- At least 60 percent of persons with diabetes should receive formal diabetes education in order to attain considerable level of awareness in the community as per the American Association of Diabetes Educators. List of Stake holders- Govt. of India, Ministry of health and Family Welfare. State Governments. NGOs and other organizations Media for awareness. Family of Diabetic patients.

Private and Public Notes of a Native Son Essay -- James Baldwin

The Private and Public Notes of a Native Son The middle of the twentieth century saw the height of the civil rights struggle of African Americans. Amid this tumultuous era rose up a generation of prominent African American writers, and among them was James Baldwin. In â€Å"Notes of a Native Son,† an essay that he wrote more than a decade after his father died, Baldwin recalls and reflects on his troubled interaction with his father, a man whom he has hated all his life. His vivid narration of his father and his personal encounters around the time his father died reveals the evolution of his view on the racial issues in America. Baldwin extensively draws on his past experience as an embodiment of the public experience shared by many other people to make a strong case for his argument. James Baldwin never fails to express his disgust for his father. Not far into the essay, he reminds the reader of the two race riots in 1943, and he mockingly describes this state of instability and social discontent that coincided his father’s death as â€Å"a corrective for the pride of his eldest son† (63). According to Baldwin, not only did his father always fail to establish contact with people, including his children, he attempted to keep his children from contact with the outside world. He forbid his children to play Louis Armstrong’s records, distrusted all white people, and constantly associated his children’s friends with the devil. Although he had good intentions, he never managed to convert them into pleasing deeds, and he, in Baldwin’s own words, â€Å"treated almost everybody on our block with a most charitable asperity† (67). Baldwin’s mental image of his father is little short than that of a tyrant. This com parison is ... ...hich, in his case, were his dead father and his new born sister. To believe in unimportant things such as skin color will only led to one’s destruction, because, as he comments, â€Å"hatred, which could destroy so much, never failed to destroy the man who hated.† (84). He maintains that accepting things as they are while at the same fighting with one’s full strength against injustice are two conflict ideas that one has to hold in mind. Baldwin does not intend to teach his moral discovery to the reader as an absolute truth. In fact, he concedes that he too has questions that the future will answer. However, supported by his narration and analysis of his private and the public experiences, he makes a strong argument. Works Cited Baldwin, James. â€Å"Notes of a Native Son.† 1995.
