Britain is a diverse and multicultural society Essay

Britain is a diverse and multicultural society - Essay Example Such people experience multiple problems and disabilities and are often in need of complex packages of treatment and social care. These are very often not forthcoming as and when required. This situation gives rise to many issues for the families of such aged and for the professionals who are supposed to care for them. Hospitals still maintain a discriminatory allocation of resources amongst various ailments affecting the old.For instance high quality care is provided in terms of inpatient hospice and palliative care for people with cancer, whereas dementia diagnoses suffer neglect mostly. Older people suffering from dementia pose complex problems and disabilities, and also need systems of care that require partnership and collaboration between different groups of care providers in differing settings. Health care systems must be reoriented to develop empathy laced health care services to meet the medical and social needs of this group. Effective care must reach into the hospital, int o people's homes and into nursing and residential homes within the community. This paper explores as to how multidisciplinary health care teams can improve care rendering systems, concerning dementia patients amongst old, by taking into account the physical, psychological and social aspects to improve discharge rates. Medical 2. Rationale Medical world has fully realized that dementia is a major problem. Specifically in individual patients of 65 or more years in age, there is substantial morbidity and mortality that is often managed badly; for the hospital there is delayed discharge and problems associated with nursing confused. And the incidence is very large in a globe that is fast ageing. Dementia debilitates 4% of people over the age of 70, which increases to an alarming 13% in case of those over the age of 80 (Hofman, 1991).More telling is the fact that the median length of survival from diagnosis to death is eight years, and during this time there is a progressive deterioration in ability and awareness. Many ethical issues become relevant as present medical systems get about the care of people with dementia who are, often, not even able to communicate their wishes (Albinsson & Strang, 2003). For instance, some current issues include the best use of antibiotics in the treatment of pneumonia and of feeding tubes for hydration and nutrition. However, less than 1% of patients in inpatient hospices have dementia as their primary diagnosis (Christakis, 1996).The enormity of the issue become clear as one considers that it is conservatively estimated that there are about 700,000 dementia patients in UK alone. It has been long established that the incidence of dementia increases with age and is thought to double every five to six years after the age of 65. The health and social care of dementia patients in UK costs a staggering 1bn and more annually. Some estimates project that by 2020 UK would have about one million dementia patients. Given the acuteness of the disease, given that it affects mostly old and that present system addresses the task inadequately it is only pertinent that this paper examines a multidisciplinary system which is

Newest Aircraft on Air Essay Example for Free

Newest Aircraft on Air Essay The F-35 varieties are designed to replace the older versions of aircrafts because these aircrafts that are used by the Armed Forces are susceptible to errors and risks, which are the common grounds for aircraft accidents. This research paper discusses the new technology behind the making of F-35 Lightning which has three (3) variants: (1) F-35A CTOL, (2) F-35B STOVL, and (3) F-35C CV. F-35 Lightning Design and Combat The F-35 Lightning is designed to take over the U.S. Air Force’s A-10 and F-16, the U. S. Navy’s F/A – 18, U.S. Marine Corps’ AV-8B Harriers and F/A -18, and U.K. Harrier GR.7 and Sea Harriers. The F-35 is also made for unusual air-to-air combat performance, and uses advance stealth to avoid being detected as it employs a powerful sensor in locating, targeting, and destroying multiple enemy fighter aircrafts. With the supersonic speed, F-35 has the most powerful engine among fighter planes and is capable of carrying weapons internally and avoiding aerodynamic drag of external stores to increase its agility reaching 9 g’s. In stealth mode, it can carry internal weapons load which includes two (2) 2,000 pound joint direct attack munitions (JDAMS) and two (2) advanced medium range air-to-air missiles (AMRAAM). The F-35 can be utilized in either close-in or long-range air-to-air combat. Variants F-35A Lightning Overview The F-35A (see Figure 1[i]) fits for the U.S. Air Force for the conventional takeoff and landing (CTOL) which uses a conventional runway for takeoff and landing. The internal capacity of fuel is around nine (9) tons which sustains an unrefueled range of at least 1,200 miles without external tanks. It also carries a 25 mm GAU-22/A cannon internally. The standard weapons load is two (2) AIM-120C air-to-air missiles and two (2) 2,000-pound GBU-31 JDAM guided weapons. In order to attain all air-to-ground and air-to-air ordnance, the internal weapons bay can be reconfigured. When the stealth is no longer needed in a mission, the F-35A pylons are brought with ordnance that gives the aircraft a weapons payload of at least 18,000 pounds. (Lockheed Martin) Features and Comparisons with Older Models The F-35A is able to exceed the performance of the F-16 due to several reasons: (1) stealth, (2) expanded range on internal fuel capacity, and (3) superior avionics. Also other features and abilities like the survival, effectiveness and support are dramatically improved in this aircraft. In comparison with the F-16, F-35A also includes an interior gun and a refueling container. The maneuver characteristics are the same with the F-16 with comparable instant and sustained â€Å"High-G† performance. On the other hand, unlike the F-16, the aircraft is stealthy and has the capability of first-look, first shot. The information gathered from sensors is put together or sorted out before being placed to the helmet-mounted or head-down displays. The aircraft also has advanced electronically scanned array radar. To add more, it also contains internal laser designator and infrared sensors. The range and payload for F-35A as mentioned above is highly greater than the older aircraft models. Design and Flight Tests The release of F-35A can surely improve the ability of the pilot in assisting in combat campaigns at longer ranges because of the large fuel capacity and the engine design which is single. As mentioned above the F-35A can carry more than 18,000 pounds of internal fuel and also can carry external fuel as well. This addresses the concern of increased combat scope and longer period spent on the base which is the experience on other aircrafts. For the flight tests, the Joint Strike Fighter X-35 demonstrator aircraft set a number of flight standards. The X-35A conventional take off and landing had a recorded 27 flights (highest), 27.4 flight hours (highest), 6 pilot checkouts (most), two cancelled flights (fewest) and a 6 1/3 flights per week(highest) in the first month of aircraft testing. The recording was established from October 2000 until August 2001. The first F-35 demonstrator aircraft left the Air Force’s runway in Plant 42, Palmdale, California on October 24, 2000 and reached Edward Air Force Base, California to begin the flight test program. On November 7, 2000, the F-35A was fueled from a KC-135 tanker for the first time and was able to record its longest flight of 2 hours and 50 minutes. It completed its test flight on November 22 2000 after finishing 27 flights in 30 days and achieving the first JSF supersonic flight the day before. It was brought back to Palmdale to be converted to STOVL F-35B. (Global Security) The U.S. Air Force is set to receive its first F-35 aircraft by 2008; however the initial operational capability (OIC) for the service will be available in 2011. F-35B Lightning Overview The F-35B (see Figure 2[ii]) is designed for the U.S. Marine Corps and the U.K. Royal Air Force and Royal Navy and is regarded as the world’s first short takeoff/vertical landing (STOVL) aircraft which has the ability to operate regularly at supersonic needs. This feature makes F-35B to operate from small ships, roads, and austere bases. It deploys near front-line combat zones which shrinks the distance greatly from the base to the target which also increases sortie rates while removing the need for logistics support. The internal fuel capacity of F-35B is seven (7) tons that provides unrefueled range of 900 miles without the use of external tanks. Its standard weapons load is two (2) AIM-120C air-to-air missiles and two (2) 1,000-pound GBU-32 JDAM guided weapons. It can also load six GBU-38 small-diameter bombs, and also huge choices of air-to-ground missiles, dispensers, and guided weapons. Same as F-35A, the internal weapons bay is reconfigurable for air-to-ground or air-to-air ordnance or a blend of both. If stealth is not required, F-35B external pylons are loaded with ordnance which gives the aircraft a weapons payload of more than 15,000 pounds. It is also recognized as the first STOVL stealth fighter. (Lockheed Martin) Comparison with other models The F-35B is said to replace the old AV-8B Harrier STOVL attack jets because of their support difficulties. According to Charles Davis (2006), the F-35B has a 25mm â€Å"missionized† gun which is put in the belly of the said aircraft and has a combat scope of at least 450NM. This combat radius is twice the specs of other STOVL fighters. The lift fan which is shaft-driven, including the vectoring rear exhaust nozzles provides power and abilities to the aircraft to (1) take-off in little distances, (2) increase speed reaching supersonic speeds in level flight, and (3) land vertically due to the lift-fan system. â€Å"The F-35Bs total vertical lifting thrust is about 39,700 pounds (the aircraft weighs about 30,000 pounds) which is more than 14,000 pounds greater than the engine alone would produce without the lift fan. The F-35B will be the worlds first operational supersonic STOVL aircraft today†. (Davis, 2006) This kind of aircraft that is going to be used by the U.S. Marines and the UK Royal Air Force is unique from the other kinds of aircraft because of its short takeoff/vertical landing capability. As mentioned in the first requirement for achieving this capability, the airplane must have more vertical lift than weight. The first requirement is regarded to have difficulties in achieving it. The airplane must have a smaller weight and have an increased thrust-to-weight ratio. The second requirement is fine controllability in every axis of the airplane at zero airspeed. The transition between up-and-away flight and hover must be carefully taken into consideration. Other critical factor that can affect the aircraft’s overall performance is â€Å"the airplanes hover footprint, which is the propulsion systems impact on the ground surface or carrier deck. The method in which thrust is developed is the key in producing a benign footprint†. (Global Security) Factors that must be considered are noise levels and heat effects on the deck and on the aircraft itself. Aside from the shaft-driven lift fan the aircraft has slightly shorter scope because the space utilized by the fan system for some of the fuel in the Air Force variant. Still, the aircraft has more than twice the range of an AV-8B on internal fuel and can carry a bigger payload. Pointing engine thrust directly down produces a tremendous amount of reflected energy, which results in all kinds of effects that make the life of the structures lessen. Acoustic considerations are material considerations because they affect material choices for the underside of the airplane as well as for structures and payloads attached to the airplane. The aircraft shares all of the electronic gear of the Air Force variant. Cockpit layout is also virtually indistinguishable, with the exception of a thrust-vector lever for the aerial mode. â€Å"The JSF X-35 demonstrator aircraft established a number of flight test standards from October 2000 through August 2001. The X-35B short takeoff vertical landing is the first and only aircraft in history to achieve a short-takeoff, level supersonic dash and vertical landing in a single flight. It is also first aircraft to incorporate and fly a shaft-driven lift-fan propulsion system. For the record, it has tallied 17 vertical takeoffs, 14 short takeoffs, 27 vertical landings, and five supersonic flights†. (Global Security) â€Å"The Department of Defense working groups and conferences started to question the community acceptance strategies for some new weapons systems. In particular, the Joint Strike Fighter (JSF) may face a variety of challenges in some possible beddown locations†. (Global Security) The aircraft generates an extraordinary amount of thrust from its single engine, which according to preliminary analyses, contributes to noise and air pollution. Investigations in San Diego, California revealed air quality limitations that may rule out unrestricted operation of the STOVL (Short Takeoff, Vertical Landing) version of the aircraft. And these will be acquired by the USMC. The highest thrust settings for the aircrafts F-119 engine will occur during transition to and from vertical flight. Noise and pollutant emissions, especially of Nitrogen oxides may exceed those encountered in any equivalent engine. On February 2004, there were some setbacks that occurred. As detailed design progressed, the weight estimates from early in the design phase were found to be unrealistic. The program leadership was soon faced with the harsh reality that the short takeoff/vertical landing (STOVL) variant would need to lose as much as 3,000 pounds to meet performance requirements. This was an unexpected negative development, and according to a few, the said fix will be either impossible or too costly and time-consuming. For the solution, the JSF constituted a re-plan phase in order to assess a number of issues pertaining to the aircraft design. (Davis, 2006) The Special Weapons and Tactics (SWAT) discovered a way of designing the STOVL F-35 that will meet or exceed its performance requirements. The team not only removed more than 3,000 pounds of unwanted estimated weight, but also improved the structure, improved the load paths and brought increased efficiencies to the overall aircraft. â€Å"The internal bays of the F-35B STOVL variant were redesigned in late 2004 and are now shorter and reduced in width, compared to the F-35A CTOL model†. (Lockheed Martin) â€Å"This was done to address the weight of the F-35B to meet other more important performance goals. As a result, the F-35B is no longer compatible with JSOW and 2,000-lb JDAM weapons. The largest weapon this F-35 variant can carry internally, as mentioned above, is the GBU-32 1,000-lb version of JDAM†. (Lockheed Martin)

Earthquakes and their Effects :: Environment, Science, Informative

An earthquake is a trembling or a shaking movement of the Earth's surface. The dictionary meaning of the word earthquake is â€Å"shaking and vibration at the surface of the earth resulting from underground movement along a fault plane of from volcanic activity†. The word earthquake is also widely used to indicate the source region itself. The solid earth is in slow but constant motion and earthquakes occur where the resulting stress exceeds the capacity of Earth materials to support it. Earthquakes produce various damaging effects to the areas they act upon. This includes damage to buildings and in worst cases the loss of human life. The effects of the rumbling produced by earthquakes usually leads to the destruction of structures such as buildings, bridges, and dams. They can also trigger landslides. Earthquakes have varied effects, including changes in geologic features, damage to man-made structures, and impact on human and animal life. Earthquakes often cause dramatic and geomorphological changes, including ground movements either vertical or horizontal along geologic fault traces, rising, dropping, and tilting of the ground surface, changes in the flow of groundwater. Besides producing floods and destroying buildings, earthquakes that take place under the ocean can sometimes cause tsunamis, or tidal waves. Tsunamis are high and long walls of water which travel at a very rapid rate. They are notorious for destroying entire populations and cities near coastlines. In 1896 Sanriku, Japan, with a population of 20,000, suffered such a fate. Several thousand stations monitor earthquakes all over the world. Each station contains an instrument, called a seismograph, used to detect arrival times and record seismic waves.

Davy Crockett Essay

Davy did many thing through out his childhood all the way up to his adulthood. Davy was born in Tennessee on August 17, 1786 . John crockett (davy’s father) sent Davy to work for a man who was taking a herd of cattle to Virginia at age 12. Davy helped the man drive cattle for over 200 miles from Tennessee to Virginia. The trip was a little over 2 weeks, and then Davy finely returned home. Soon after, the man Wanted Davy to keep working for him. Davy was homesick but he still said yes. About one month later Davy could not stand being away from his family. So he ran away from the mans house and headed home. At age 13 Davy set out on his own, and learned to become one of the worlds greatest/and craftiest backwoodsman around. Legend says that Davy was friends with a bear and could get a raccoon to come down from a tree by just grinning at it . At age 16 Davy moved back to Tennessee with his family. In 1811 Davy’s family moved to Tennessee. They made there home near what is now the border of Alabama. By 1813 the white men had made the native Americans very made. The native Americans were called the creeks. The reason for the creeks being made is because the white men took there land. The white men thought the creeks were going to attack so they attacked first. the creeks fought back against the white men. This started a war. Davy helped the creeks fight against the white men. When Davy got back from the creek war, Polly gave birth to a daughter. Polly died in the summer of 1815. In 1816 Davy married Elizabeth Patton to care for his two children, let alone her own three children. In 1816 Davy almost died of malaria, and in 1818 Davy becomes a â€Å"court referee† in Lawrence country, Tennessee. In 1821 David Crockett was elected to the state legislature at age 35. In 1827 David Crockett was elected to the House of Representatives in Congress. David Crockett served in congress from 1827-1831, and then he served in Congress again from 1833- 1835. when he was in Congress he often made speeches and told many of his adventures. Books came out filled with information and stories about Davy’s life. They even made a lay about Davy called the lion of the west in 1831. David Crockett and a congressman Thomas Chilton wrote a book about Davy’s life. Davy was a legend while he was still living, and still is a legend to this very day. in 1835 David Crockett moved to Texas. Texas was not a state when Davy moved there. Davy was now 49 years old and he wanted to explore the frontier . Davy joined the Texas army. David fought in the Texas revolution in 183 6. the Texas Revolution was over a Mexican government that ruled Texas. The people who lived in Texas wanted to be free from the Mexicans.

Psychology: Learning by Doing Essay

A news article entitled â€Å"Keeping your DNA fit: Researchers find exercise buffs have ‘younger’ cells† was released by The Philadelphia Inquirer at the Psychology News Report Section of the American Psychological Association online. The news article was about the newest study released last January 28, 2008 stating that exercise could slow down the aging process in human beings. The authors of the study concluded that the people who exercise more take a slower course of aging than those who have been â€Å"chronically sedentary† (Flam, 2008).   The authors supported this claim with the experiment they conducted involving 67 pairs of identical twins where one of the twins had a sedentary lifestyle while the other had been mostly active and exercises regularly (Flam, 2008). The term exercising regularly has been operationally defined as â€Å"more than three hours a week running, cycling, pumping iron, or other vigorous activity† (Flam, 2008). On the other hand, sedentary has been defined as â€Å"less than 16 minutes [of exercise] a week on the average† (Flam, 2008). The comparisons of the twin’s telomeres revealed that those twins who exercise more have longer telomeres. The telomere is the part of the DNA which becomes shorter when it divides (Flam, 2008). For the old people, the telomere becomes too short for the DNA to be capable of dividing and thus, it just shut downs the cells but it continues to exist (Flam, 2008). The research still continues for the authors to be able to refine the study because there is still the â€Å"chicken-and-egg question† of whether it is the exercise that enables the people to stay young or the healthy condition that enables people to exercise more (Flam, 2008). Further studies would need to be done with this as there might be differences in the capacity of people such as the twins. Though they may have the same set of genes, there is still a difference with the environment they live in that makes them a lot healthier than the other twin and enables them to exercise more such as the type and quality of food available and the levels of stress. Indeed, the most appropriate conclusion for the study is that exercise is one of the factors that slow down the rate of aging but is not the sole reason for the slow aging process (Flam, 2008).    The news article was able to identify the basic answers to basic questions. It poses the side of the research itself and the whereabouts but does not even provide the title and authors of the study. The lead author was mentioned but this could do little compared to having the title of the study itself. In addition to this, alternative views were not presented clearly. References Flam, F. (2008).

Sociological Aspects of the Article

Sociological Aspects of the Article The article written by Jennifer Saba describes the marketing strategies of the New York Times. It is stated that in the near future this organization will charge for full online access to the articles (Saba, unpaged). This article can be related to several sociological aspects: in particular, we need to speak about the so-called digital divide and cultural diffusion of information (Murray, Linden, Kendall, p 377, 72).Advertising We will write a custom essay sample on Sociological Aspects of the Article specifically for you for only $16.05 $11/page Learn More The paper aims to show how these concepts can throw a new light on the topic of the article. Additionally, it is necessary to explain the benefits of applying sociological concepts to these topics; namely, we need to show how the concepts of digital divide and cultural diffusion can explain the new tendencies in the evolution of mass media and Internet. For a very long time, Internet has been viewed as a tool that can provide equal opportunities to people, irrespective of their income level, nationality, race, gender, and so forth. Furthermore, Internet is often referred to as the technology which is able to more connected and most importantly less hostile to one another. Nonetheless, the evidence presented in this article indicates that social inequality permeates Internet as well. At this point, we should discuss such concept as digital divide. On the whole, this notion can be interpreted as inability of a certain group of people to have access to information (Murray, Linden, Kendall, p 377). It can be also defined as the gap in access online information (Compaine, 25). This difference can be observed both between and within countries. It is also possible to say that digital divide is directly proportionate to the degree of economic and social inequality in the country or in a certain geographic region. Therefore, successful implementation of the New York Times marketing strate gy can impact a great number of people in Canada, the United States, and all over the world. The commercialization of Internet will significantly widen knowledge divide and diminish the opportunities of many people. As a rule, this concept is usually used when we are speaking about technologies but in this case it is more applicable to information, itself. The decision, taken by the management of the New York Times, can lead to significant implications for online. Provided that this strategy will prove successful, many other newspapers will also require payment for the access to their websites, and in the near future it will be even more difficult for low-income population to find valuable information on the Web. Certainly, the New York Time has only launched the new marketing campaign and it may be soon abolished. One should take into consideration that in the future the New York Times already tried to implement such business model but it did not succeed (Saba, unpaged). Still, thi s attempt suggests that high quality information may eventually become less and less available to low-income people.Advertising Looking for essay on communications media? Let's see if we can help you! Get your first paper with 15% OFF Learn More Overall, by applying the concept of digital divide, one can better understand the development of the World Wide Web and mass media, in general. Certainly, this is just a hypothesis which still has to be substantiated; yet, it does not seem highly improbable especially in the light of the decision taken by the New York Times. In the previous section we have mentioned the so-called cultural diffusion. It can be understood as the transmission of social practices, ideas, and cultural items from society to another (Murray, Linden, Kendall, p 72). The Internet has made the world more connected and open to cultural differences. To some extent, the websites of such newspapers as the New York Times, Wall Street Journal, or E dmonton Journal can be regarded as the agents of cultural diffusion. For many people, especially those, who live in developing countries, these websites are the windows into a different culture. Apart from that, some people living in advanced countries may be unwilling to pay for monthly subscription. If different newspapers follow the example of the New York Time, the process of cultural diffusion will become significantly slower. These are the changes that people may expect. Of course, it is not likely that every newspaper will emulate this strategy but this possibility should not be overlooked. Overall, the application of these sociological concepts is a very fruitful exercise that can give deep insights into the future trends in the development of Internet. Such approach is more beneficial than the so-called â€Å"taken for granted understanding† since it enables the scholars to take a wider look at a certain problem. The application of sociological concepts is beneficial to that extent that it allows us a separate decision can impact the community. The article, written by Jennifer Saba, focuses only on the decisions of only one newspaper, the New York Times. However, it may have profound effects on the overall accessibility of online information and cultural diffusion. At the moment, we may be witnessing the process of commercialization of Internet and the new business model of the New York Times exemplifies this process. Compaine. Benjamin.

Geography Essay Sample Summer in Different Parts of the Globe

Geography Essay Sample Summer in Different Parts of the Globe Geography Essay Sample: Summer in Different Parts of the Globe If you are going to write a college paper, it’s a good idea to look at an example first. This will help you understand the structure of an essay and what needs to be included. Here is a geography essay sample for you to reference when you write your own geography masterpiece. Often, people think that summer is warm, and the sun is always shining. This is not always the case for summer varies in different places around the world. There is not one single definition of the season when it is looked at from a global standpoint. There is a handful of differences between each country’s summer season and what it looks like. If you live in the northern hemisphere, you know that summer occurs in June, July, and August. Those who live in the southern hemisphere experience summer in December, January, and February. Not every country has their summer season at the same time. This is one of the major differences between summers in different places around the world. Another variation in summer around the world is that some places get warmer and drier while others get warmer and wetter. Drier climates often go through droughts in the summertime, which cuts back on their crop production. Tropical areas are known to be more humid, which means that summer is the â€Å"wet season†. This is also the season where the most vegetation grows in tropical countries. Hong Kong has a sub-tropical climate, which means that they grow many of their crops during the summer season. Overall, there are a few cities that are hotter than all of the rest. Kuwait City, Karachi, and Ahvaz often reach the highest temperatures when compared to others. Particularly, in Kuwait City, the temperature might reach 44 degrees Celsius, which is equivalent to 111 degrees Fahrenheit. This is common during the summer months from June to August. This city, along with Karachi and Ahvaz, experiences more than a few negative effects from the hot weather. The citizens are prone to heatwaves and poor air circulation. In the summer season of 2017 in the United States, a few states had especially hot weather. These temperatures were between 119 and 125 degrees Fahrenheit or between 48 and 51 degrees Celsius. These specific temperatures were recorded in the southwest region, including California, Arizona, and Nevada. Arizona’s capital city, Phoenix, had reached the temperature of 120 degrees Fahrenheit three times in its history. The high temperatures proved to be deadly and even resulted in heat waves. Of course, this is not what summer looks like all around the globe. In New Zealand, there can sometimes be a lack of consistency when it comes to weather. New Zealand is located relatively close to Antarctica. Recently, in January of 2017, this country should have been experiencing its summer season. Instead, it was met with a â€Å"weather bomb† which led to flooding and snowing. This is not abnormal for the country, which is located in the southern hemisphere. They have endured extreme weather conditions prior to the 2017 weather bomb. Well, there are a lot of ways that summer can present itself throughout the world. There is not one correct route to describe summer because it can look different in each city or country. Some countries have mild summers, while others have very extreme ones. Even a country’s summer season timing can vary by its location in either the northern or southern hemisphere. References: Birch, H. (2015, July 22). Where is the worlds hottest city?

Latin American Woman Essay Example | Topics and Well Written Essays - 1000 words

Latin American Woman - Essay Example Generally the cases represented in this scenario are the low class, middle class or the upper class and the variety of the classes of people has a completely direct effect between the people, their relative powers and status in the society (Ninenth, 2002). In the actual life situations, the members of the upper class always have more political power and influence on the decisions made within the society compared to all the other classes of people. This people include the politicians and the wealthy and stable business individuals in the society and issues to do with major decisions in the society. This population is small and comprises of about 1 or 2 percent of the communities mostly born within this social class. The middle class individuals fall in a category of the society which clearly faces the most of contention in relation to the societal perception because it falls within the periphery of the high class and the middle class and can either ascend to the high class or descend to the low class members of the society. They form the people of white collar jobs and either is working or the individuals with stabilizing businesses with good capital able to sustain almost their entire capital needs and demands. It is generally believed especially in Latin America that the low class individuals and families are living in crime ridden areas with poor infrastructure. The areas are perceived to be having decaying environment with almost zero civil services and the poor characterisation of basic amenities. The low class members of the society are characterised by the homelessness and the rampant and wide spread characterisation of unemployment of the individuals within the society. (Galeano, 1999) The social classes of the individuals has a completely great repercussion on the lives of the individuals plus the lives of their children for example the individuals social class will probably determine the kind of school an individual attends or the kind of facilities he is to use especially for learning and recreation and this will have either a negative addition to his learning or general development especially of the young individuals. The variety of the classes also has effect on the health of an individual in relation to the attention he obtains from the medical personnel and the ability to pay for better and more efficient health services. The jobs also vary according to the classes, those individuals in the middle or upper classes are always enjoying greater freedom in their jobs whereas the individuals in the low classes face job opportunities with great constraints hence don’t have enough freedom of issues herein. The courts and policing are also biased in relation to the social classes in the society favouring mostly the middle and high classes in relation to the low class. The women in Latin America face a number of issues especially of socio economic aspects like the deprivation of their human rights to education and their genera l empowerment to ensure that they fully achieve the ultimate goal of life. In Latin America women make up to 50 % of the HIV/AIDS patients while globally the percentage of the affected males is higher than the females and the examination of the prevalence in the Latin America is showing that the prevalence and rations of the infection of women to men affected in Latin America is significantly narrowing down (Hillary, Karen, &

The Retention of Students in Higher Education Research Paper

The Retention of Students in Higher Education - Research Paper Example In such a context it is imperative that providers and students understand the factors which can help or hinder student success, so that time and energy are not wasted on negative outcomes and experiences. An important way of measuring student (and by implication also provider) success is to examine retention rates and explore reasons why some courses are, by this measure at least, more successful than others. This method has the advantage of being quantitative in terms of providing the raw data for the study, and qualitative in terms of exploring the underlying reasons for trends in this data. Criminal justice programmes are among the most popular choices for undergraduate students and they are offered in a wide range of public and private college and university settings. Popularity has its disadvantages, however, in that larger numbers of students can mean more pressure on resources, lower retention rates, and considerable wastage in the system. The purpose of this empirical study is first to gather data on the range of criminal justice programmes available in the UK and to analyze rates of retention on a comparative basis. This will establish a quantitative basis for further examination of underlying trends in this area and will highlight any variations that emerge. This factual information will be obtained from Funding Council records, department Chairs, and publicly available information from university and other websites and databases. The gathering of data alone provides only part of the picture, namely what is actually happening in terms of student retention on Crim inal Justice Courses in the UK.

Management in context Assignment Example | Topics and Well Written Essays - 1000 words

Management in context - Assignment Example According to the authors of this article, in order to avoid the negative connotation that have become associated with the title ‘manager,’ they have resorted to titles like professional, entrepreneur or project leader. The author not only expresses strong feelings about the behavior of managers but also condemns it, thereby calling for changes to be made on the responsibilities that go with this title. The way every context that the authors looks at the title is simple spellbinding, which therefore calls for serious research and analysis on management as a discipline in order to correct the situation (Brocklehurst, Grey and Sturdy, 2010). Surprises in JA2 Academicians and intellectuals in our business school are increasingly joining the chorus of castigating and condemning management practices which is a complete departure from the initial support that they exhibited on the management practice as we know it today. This article explores managers’ obsession with the so-called intellectual slavery with roots in explicit ideas that senior personnel in organization acquired in their respective business schools. According to the authors, the MBA has become a means of acquiring appropriate ways of management to gain self confidence for legitimate social privileges in senior management (Sturdy, Brocklehurst, Winstanley, et al, 2006). They are taught that managers cannot be trusted hence should maximize shareholder’ wealth in order to reconcile their interest and that of their employers (shareholder) as a way of overcoming the agency problems. This is particularly evident in cases where opportunities for application of management practices in organization are viewed as inappropriate within organizations. Therefore, tight monitoring should be an appropriate strategy of preventing people from pursuing opportunistic behavior at the expense of practices that are of the common good to the organization. It is in the context of this disparity that a regulatory framework should be devised as a mean of safeguarding the interests of the suppliers, customers, employees and most importantly, shareholder. The article however, points out the need to explore academic knowledge beyond that of transforming ideas of the discursive content to identify towards ideas associated with effective work .I suggest business school should provide moral theories inspired to free them from immoral responsibility by ensuring centrally based education in the organization. The evidence In both articles, authors defend their work by use of books, journals, web pages and research and study institution. According to Sturdy, Brocklehurst, Winstanley, et al (2006), there is more concern on the de-legitimization of a company as institutions and management as a profession. This will be brought about partly by the acceptance of these thoughts when ignored as vital elements of management. Several scholars have recently voiced their concern about the current state of management research and pedagogy. While training people on organization design focusing on transaction cost economics, it is imperative for trainers to ensure that there is firm monitoring as well as control of people so as to curb opportunistic behavior (Brocklehurst, Grey & Sturdy, 2010). Comparison The term management generally refers to

While usual measures of concern about crime repeatedly prove between 35 percent and 55 percent of the residents of England show some type of apprehension about becoming a victim, surveys tell that a considerable number of individuals in fact worry for their personal wellbeing on a daily basis. Contrary to usual perception, this level of fear has reduced since 1990s according to British Crime Surveys from 40% to 27% in 2003 in the United Kingdom. As a result, one can differentiate between fear and broader apprehension.

Literature review Essay Abstract: Supply chain Management has assumed a significant role in firms performance and has attracted serious research attention over the last few years. A literature review reveals a considerable spurt in research in theory and practice of SCM. Combining and informing on features of Supply Management and distribution Management. This integration has resulted in the concept of extended enterprise and the supply chain is now manifest as the collaborative supply chain across intercompany borders to maximize the value across the entire supply chain. A large number of research papers have been published in various journals in last two decades. In this paper an attempt is made to review the status of literature on Supply Chain Management. A literature classification scheme is proposed. A total of 588 articles from 13 refereed academic journals are classified into articles in five methodologies i.e. Exploratory, Normative, Methodology, Literature Review and Hypothesis testing. This literature review finds that exploratory type of research is mostly preferred it is expected that with the maturity of SCM the hypothesis testing method will pick up. The articles are further categorized in fifteen categories on the basis of content analysis. Based on this review, some possible research issues are identified. Keywords: SCM, Supply Chain strategy, Literature Review. those with average performance. 1. INTRODUCTION Traditionally, Supply Chain Management (SCM) has been a melting pot of various aspects, with influences from logistics and transportation, operations management and materials anddistribution management, marketing, as well as purchasing and information technology (IT). Ideally, the allencompassing philosophy of SCM embraces each of these functions to produce an overall supply chain strategy that ultimately enhances firm performance (Croom et al. 2000; Wisner and Tan 2000). In actuality, the literature is still very fragmented and although several studies purport to discuss supply chain issues, most of the existing research only examines one link of the chain, or most importantly only focuses on one ingredient in the supply chain performance mix. Six major movements can be observed in the evolution of supply chain management studies. Creation, Integration, Globalization, Specialization Phases One and Two, and SCM 2.0 These phases are given in Table 1. In the current competitive scenario supply chain management assumes a significant importance and calls for serious research attention, as companies are challenged with finding ways to meet ever-rising customer expectations at a manageable cost. To do so, businesses must search out which parts of their supply-chain process are not competitive, understand which customer needs are not being met, establish improvement goals, and rapidly implement necessary improvements. Previously manufacturers were the drivers of the supply chain managing the pace at which products were manufactured and distributed. Today, customers are calling the shots, and manufacturers are scrambling to meet customer demands for options/styles/ features, quick order fulfillment, and fast delivery. Manufacturing quality a long-time competitive differentiator is approaching parity across the board, so meeting customer’s specific demands for product delivery has emerged as the next critical opportunity for co mpetitive advantage. Companies that learn how to improve management of their supply chain will become the new success stories in the global market place.

All rights reserved The six stage evolutionary era depicts that in a particular era which strategy was emphasized. For instance in the sixth era information Technology was given priority and IT enabled supply chain was the burning issue. In the 1990s industries began to focus on â€Å"core competencies† and adopted a specialization model. Companies abandoned vertical integration, sold off non-core operations, and outsourced those functions to other companies. Web 2. 0 is defined as a trend in the use of the World Wide Web that is meant to increase creativity, information sharing, and collaboration among users. The term supply chain management was first coined by an American industry consultant in the early 1980s. However the concept of supply chain in management, was of great importance long before in the early 20th century, especially by the creation of the assembly line. This era of supply chain management studies was highlighted with the development of Electronic Data Interchange (EDI) systems in the 1960s and developed through the 1990s by the introduction of Enterprise Resource Planning (ERP) systems. This era is characterized by the globalization of supply chain management in organizations with the goal of increasing competitive advantage, creating more value-added, and reducing costs through global sourcing Specialization within the supply chain began in the 1980s with the inception of transportation brokerages, warehouse management, and non asset based carriers and has matured beyond transportation and logistics into aspects of supply planning, collaboration, execution and performance management. presents various connotations given by various researchers; then a literature classification scheme is explained and a research agenda is suggested after identifying the gaps between theory and practice of SCM. SCM research has included a number of literature reviews and historical studies published in the top scholarly journals in the fields of logistics, logistic   management, purchasing and SCM (Croom et al. 2000; Carter and Ellram 2003; Rungtusanatham et al. 2003). SCM literature reviews have also been done in the past. However, for the most part these reviews have been descriptive (offering basic frequencies for topics covered etc.) or normative. Given the increasing focus on SCM in both academic and practitioner literature streams, a review of the concepts, topics, analysis methods and levels of analysis across thirteen academic journals was undertaken. This research investigates the history of the SCM literature looking at the various trends and developments in the field

Behaviour Management of Crying Toddler in Dentistry

Behaviour Management of Crying Toddler in Dentistry Management of Sobbing Tot In A Pediatric Dental Office- A Review ABSTRACT The most common way by which child expresses fear and anxiety is by crying at dental office. Proper knowledge and understanding is required to deliver effective dental treatment to a child by the application of various behavioral management techniques. Treating a crying child is one of the most demanding and tiring situation encountered in dentistry. Behavior management in a crying child is a comprehensive continuous methodology targeted to build relationship between child, parent and doctor aimed at eliminating fear and anxiety and ultimately building trust. This article was aimed to review the various reasons for stimulation of cry of child in dental office and behavior techniques employed by the dentist for proper management of the child. Key Words-Anxiety, Behavior Management, Fear INTRODUCTION Behavior management is a comprehensive continous methodology targeted to build relationship between child, parent and doctor aimed at eliminating fear and anxiety and ultimately building trust. As most of the young children do not cooperate during dental procedures, thus a dentist plays a crucial role to forestall a positive dental attitude, to guide the child through their dental experience and to perform quality treatment safely. 1 Children and young adults and indeed all patients, exhibit some form of anxiety or fear when about to receive dental care. Many factors have been proposed as contributory to children’s anxiety about dental procedures which include the dental clinic environment, equipments, past dental treatment experience and the attitude of the dental staff. To address these causative factors, various behavior management strategies are being practiced which including verbal and non- verbal communication, tell show do distraction , presence or absence of parents in the surgery, modeling, audio visual aids , positive reinforcement , visual aids, physical restraints, HOME(Hand over Mouth) technique, sedation, general anesthesia etc. 2 Dental anxietyand fear has been a constant dynamic of the child patient. 2 A child patient tends to be anxious and fearful during dental treatment due to previous traumatic experience in dental office or during hospitalization for other purposes. It is very difficult to carry out any dental procedure if a child is uncooperative in dental office. It is crucial that a dentist must understand and share the feelings of a child and show concern before starting any treatment.3 Treating a crying child is one of the most taxing and difficult job for a dentist due to unanticipated attitude of a child during treatment. Delivery of effective dental treatment in a crying child requires incorporation of various behavior modification techniques. Thus acquisition of skills that allow a dentist to handle such â€Å"uncontrollable† situations in the best possible way is of utmost importance. A dentist should take a child’s cry as an advantage rather than a drawback as crying is a mode of expression of the personality traits, hence should be used as a diagnostic tool.3 Dental fear and anxiety is a dilemma concerning pediatric patients, their parents, and dental professionals. Its prevalence in children and adolescents ranges from five percent to twenty percent. Fearful pediatric patients often tend to be uncooperative during dental visits. This renders treatment difficult or even impossible, causes occupational stress among dental staff, and increase the chance of discord between dental professionals and patients or their parents. Dental fear and anxiety are the main cause of dental avoidance that leads to deterioration of ones oral health and may impair ones psychosocial functioning and quality of life. 4 Dental Fear: Dental fear is defined as an unpleasant emotion caused by the threat of danger, pain, or harm during dental treatment. 5 It is characterized by change in body physiological symptoms due to changes in cardiovascular and respiratory systems. The response of a child usually occurs by a real or imagined threat to his own safety. The patient readies himself in a fight or flight stance to either escape the stimulus or stands and conquer it. Rachman’s model of fear acquisitioning is one of the most accepted theor, which is supported by several studies. This theory has proposed that fear might develop through three pathways: direct conditioning (classical conditioning), vicarious conditioning (modelling), and information/ instruction. The second and third pathways are manifestations of indirect fear acquisition.3 Dental Anxiety: Anxiety is a feeling of worry, nervousness, or unease about something with an uncertain outcome. Dental anxiety is defined as â€Å"an abnormal fear of visiting the dentist for any dental procedure and unjustified anxiety over dental procedures† and may have psychological, cognitive and behavioral consequences. Dental anxiety may be a problem in childhood as it is associated with poor oral health outcomes and an increased dependence on costly specialist dental services. Children who show more anxious behavior have a greater chance of having dental diseases as compared to children who are non-anxious in the dental office. Dentists need to understand the anxiety of the child and implement procedures that enhance a feeling of control which include giving child’s choices, helping within treatment or otherwise manipulating dental objects and acknowledging the child’s experience.4 Due to less communication skills exhibited by children, they are not able to properly express their fears and anxieties. When children cannot manage, they attempt to escape the upcoming event. This ultimately leads to crying of a child which also is a way of a child to show their anxiety and discomfort. 3,4 Different anxieties and fears that children have about visiting the dentist are: Mostly children are anxious during a new experience. There is uncertainty about what is going to happen which increases the child’s restlessness. Past negative experiences associated with medical treatment may be co-related with more anxiousness in dental treatment as well. Previous fearful dental visits have also been related to poor behaviour at subsequent visits. The parents who are unable to contain their own dental anxieties, make the child more conscious. Mass mediaandcartoonsalso contribute to the negative image of dentist which may lead to development of dental fear. Management of Crying child during Dental Treatment Successful treatment of a disruptive child depends partially upon selection of an appropriate behavior management technique. Each child possess different behavior pattern on visiting the dentist. For managing a child in dental office various factors have to be seen like -the type of behavior, the child’s anxiety, age of the child, child rearing techniques, personality variables, parental attitudes toward behavior management techniques, dental treatment to be rendered and the legal implications.6 Behavior management is of children in clinics is an integral part of pediatric dentistry. It is not just the application of individual technique formulated to deal with individuals but rather a comprehensive methodology meant to build a relationship between patient and dental professional. Behavior guidance is based on scientific principles but also requires skills in communication, coaching, tolerance, and active listening. The aim of the behavior management is to instill a positive dental attitude on patient, alleviate fear and anxiety, deliver quality dental care, build a trusting relationship between dentist, child, and parent and create long term interest on patient’s part so as to facilitate ongoing prevention and improved dental health in the future. Since the child may enter the dental office with some fear and anxiety, the first objective of the dentist should be to put the child at his ease and make him realize that this experience is not unusual. It is better to have morning appointments for patients and dentist should be realistic and reasonable to the child. This may help in developing a positive attitude of the child towards the dentist. Parents exert a significant influence on the behavior of their children. Most of the characteristics of the child like behavior, personality, anxiety and reaction to stress are directly influenced by parent’s characteristics. Parents should be educated before their child’s visit as it may be helpful in promoting a positive dental experience. Behavior Guidance is a continuum of interaction involving the dentist, the dental team, the patient and the parent directed towards communication and education which ultimately builds trust and allays fear and anxiety. Both non pharmacological and pharmacological behavior guidance techniques may be used by dental health care providers in providing oral health care for infants, children, adoles ­cents, and persons with special health care needs. Some of the behavior modifications techniques include:- Communication and communicative guidance First objective in successful management of a crying child is to establish communication. By involving the child in communication, the dentist not only learns about the patient but also helps in relaxing the patient. The fear and anxiety of the child demands that each step should be explained. Appropriate use of commands may help the child develop a positive attitude toward oral health Distraction Distraction is a newer method of behavior management of diverting the child’s attention from sounds or sight of dental treatment, thereby reducing anxiety. Audio or Audiovisual distraction will help in eliminating dental sounds and sight of the dental treatment, hence helping in gaining control of the child. Voice control Another modification of behavior modification in crying child is controlled alteration of voice volume, tone, or pace to influence and direct the crying child’s behavior. It helps the dentist to gain the patient’s attention and compliance and to avert negative behavior. Positive reinforcement Positive reinforcement is an effective technique to reward desired behaviors and, thus, strengthen the recurrence of those behaviors. If a child stops crying or show good behavior he should be rewarded with tokens or toys. Tell-show-do Tell-show-do technique can help in modifying the behavior of a crying child. It is the cornerstone of behavior management given by Addleston in 1959. The technique involves the dentist telling the child what is going to be done in words the child can understand. Second, the dentist demonstrates the child exactly how the procedure will be conducted and then, without deviating from the explanation and demonstration, completion of the procedure. Conscious Sedation Nitrous oxide/oxygen inhalation helps in providing a minimally depressed level of consciousness which helps in reducing anxiety and enhancing effective communication in a crying child. Its onset of action is rapid and the child responds appropriately to physical stimulation and verbal commands. The effects are reversible and recovery is rapid and complete. But before giving conscious sedation, proper diagnosis and treatment planning must be done. 6 Other techniques include hand-over-mouth exercise (HOME) and medical immobilization. The behaviors of the dentist and dental staff members play an important role in behavior guidance of the pediatric patient. Successful behavior management enables the oral health team to perform quality treatment safely and efficiently and to nurture a positive dental attitude in the child. 6 Knowing that pain is not the only reason for a child to cry during dental treatment will help parents and dentists to understand why a child’s behavior is managed a certain way. As the children learn to cope with the dental situation, the crying usually eases up. The learning process varies in every child. The role of the pediatric dentist is to help the child to get through his dental experiences so that the child may develop a positive attitude towards dentistry. CONCLUSION The most common emotional upsets exhibited during dental treatment are anxiety and fear and the most common way a child expresses fear is by crying at the dental ofà ¯Ã‚ ¬Ã‚ ce. The pediatric dentist can use an appropriate behavior management technique to make the child cooperative throughout the dental procedure and can help the child to develop a positive attitude towards dentistry. 1

Stonehendge :: Architecture History Art Essays

Stonehendge When you think of Stonehenge, you think of the Ancient Druid Civilization that supposedly built it, this is in fact not true. In this essay, I will show you the building of one of the most amazing art forms in history, as well as give some insight on legend. Certainly the best known of all megalithic sites, Stonehenge stands in isolation on the undulating chalk of Salisbury Plain, west of Amesbury, between the busy A303 and A344 roads. At first sight, this unique and enigmatic site appears smaller than imagined, but the tallest upright stone is 6.7m (22ft) high, with another 2.4m (8ft) below ground. The outermost element of the site is the Avenue that runs straight down a gentle slope for 530m (560yds) into Stonehenge Bottom. The Avenue consists of twin banks about 12m (40ft) apart with internal ditches, and it begins at the entrance to the earthwork enclosure. Here is the Heel Stone, a large upright unworked sarsen (hard sandstone) that lies immediately adjacent to the A344 road. It is worth noting that the nearest source of stones of the size represented by the large sarsens at Stonehenge is on the Marlborough Downs, about 30km (18mi) to the NE. One may only imagine how these stones had been moved; it only seems logical that these stones (the heaviest of which weighs about 45 tons) were transported on some type of sledge. Moving inwards from the Heel Stone is an earthwork enclosure that consists of a ditch and an interior bank, the height of which was calculated by Professor Atkinson as being about 1.8m (6ft). It is known that there were at least two entrances, the one now visible (facing NE) and one to the south. Lying within the entrance is an unworked and now recumbent sarsen stone, stained a rusty red caused by rainwater acting on iron, and known as the Slaughter Stone. Arranged around the inner edge of the earthwork bank were originally four small uprights: the Station Stones, of which two are still visible. Immediately adjacent to the bank is a ring of 56 pits, known as the Aubrey Holes, marked by circular concrete spots. The area between the inner edge of the bank and the outermost stone settings includes at least two further settings of pits: the Y and Z holes. On the central area of the site, there are the stone settings, the sophisticated arrangements that set Stonehenge apart from any other prehistoric monument in Europe.

VILLAMAYOR GR&SEC: VI-MALINIS TEACHER:MR:PENIDA A  detergent  is a  surfactant  or a mixture of surfactants with â€Å"cleaning properties in dilute solutions. â€Å"[1]  These substances are usually alkylbenzenesulfonates, a family of compounds that are similar to  soap  but are more soluble in  hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxyl (of soap) to bind to calcium and other ions found in hard water.In most household contexts, the term  detergent  by itself refers specifically to  laundry detergent  or  dish detergent, as opposed to  hand soapor other types of cleaning agents. Detergents are commonly available as powders or concentrated solutions. Detergents, like soaps, work because they are  amph iphilic: partlyhydrophilic  (polar) and partly  hydrophobic  (non-polar). Their dual nature facilitates the mixture of hydrophobic compounds (like oil and grease) with water. Because air is not hydrophilic, detergents are also  foaming agents  to varying degrees.Pesticides  are substances or mixture of substances intended for preventing, destroying, repelling or mitigating any  pest. [1]  Pesticides are a special kind of products for crop protection. Crop protection products in general protect plants from damaging influences such as weeds, diseases or insects. A pesticide is generally a  chemical  or biological agent (such as a  virus,  bacterium,  antimicrobial  or  disinfectant) that through its effect deters, incapacitates, kills or otherwise discourages pests.Target pests can includeinsects, plant  pathogens, weeds,  molluscs,  birds,  mammals,  fish, nematodes (roundworms), and  microbes  that destroy property, cause nuisance, spread disease or are  vectors  for disease. Disinfectants  are substances that are applied to non-living objects to destroy  microorganismsthat are living on the objects. [1]  Disinfection does not necessarily kill all microorganisms, especially resistant  bacterial spores; it is less effective than  sterilisation, which is an extreme physical and/or chemical process that kills all types of life. 1]  Disinfectants are different from other  antimicrobial agents  such as  antibiotics, which destroy microorganisms within the body, and  antiseptics, which destroy microorganisms on living  tissue.Disinfectants are also different from  biocides  Ã¢â‚¬â€ the latter are intended to destroy all forms of life, not just microorganisms. Disinfectants work by destroying the cell wall of microbes or interfering with the metabolism. A  preservative  is a naturally occurring or synthetically produced substance that is added to products such as foods,pharmaceuticals, pai nts, biological samples, wood, etc. o prevent  decomposition  by  microbial  growth or by undesirable  chemicalchanges. Food additives  are substances added to food to preserve flavor or enhance its taste and appearance. Some additives have been used for centuries; for example, preserving food by  pickling  (with  vinegar),  salting, as with  bacon, preserving  sweets  or using  sulfur dioxide  as in some  wines. With the advent of processed foods in the second half of the 20th century, many more additives have been introduced, of both natural and artificial origin.Medicine  is the  applied science  or practice of the  diagnosis,  treatment, and prevention ofdisease. [1]  It encompasses a variety of  health care  practices evolved to maintain and restore  health  by the  prevention  and  treatment  of  illness  in  human beings. Contemporary medicine applies  health science,  biomedical research, and  medical te chnology  to  diagnose  and treat injury and disease, typically through  medication  orsurgery, but also through therapies as diverse as  psychotherapy,  external splints & traction,  prostheses,  biologics,  ionizing radiation  and others.Bleach  has been serialized in the Japanese manga anthology  Weekly Shonen JumpsincAugust 2001, and has been collected into 56  tankobon  volumes as of September 2012. Since its publication,  Bleach  has spawned a  media franchise  that includes ananimated  television series  that was produced by  Studio Pierrot  in Japan from 2004 to 2012, two  original video animations, four animated feature films, seven  rock musicals, and  numerous video games, as well as many types of  Bleach-related  merchandise.Petroleum jelly,  petrolatum,  white petrolatum  or  soft paraffin,  CAS number  8009-03-8, is a  semi-solid  mixture of  hydrocarbons  (with  carbon  numbers mainly higher than 25),[1]  originally promoted as a topical  ointment  for its healing properties. Its folkloric medicinal value as a â€Å"cure-all† has since been limited by better scientific understanding of appropriate and inappropriate uses (see  uses  below). However, it is recognized by the U. S. Food and Drug Administration  (FDA) as an approved  over-the-counter  (OTC)  skin  protectant, and remains widely used in  cosmetic  skin care.Aluminium foil  is  aluminium  prepared in thin  metal leaves, with a thickness less than 0. 2 millimetres (8  mils), thinner gauges down to 6  Ã‚ µm (0. 2  mils) are also commonly used. [1]  In the USA, foils are commonly gauged in  mils. Standard household foil is typically 0. 016 millimetres (0. 6  mils) thick and heavy duty household foil is typically 0. 024 millimetres (0. 9  mils). The  foil  is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are so metimes  laminated  to other materials such asplastics  or  paper  to make them more useful.Aluminium foilsupplanted  tin foil  in the mid 20th century. Corn starch is used as a  thickening agent  in  soups  and liquid-based foods, such assauces,  gravies  and  custards  by mixing it with a cold liquid to form a paste or slurry. It is sometimes preferred over  flour  because it forms a  translucent  mixture, rather than anopaque  one. As the starch is heated, the molecular chains unravel, allowing them to collide with other starch chains to form a mesh, thickening the liquid (Starch gelatinization).

Indian  mathematics  reached Baghdad, a major early center of Islam, about ad 800. Supported by the ruling caliphs and wealthy individuals, translators in Baghdad produced Arabic versions of Greek and Indian mathematical works. The need for translations was stimulated by mathematical research in the Islamic world. Islamic mathematics also served religion in that it proved useful in dividing inheritances according to Islamic law; in predicting the time of the new moon, when the next month began; and in determining the direction to Mecca for the orientation of mosques and of daily prayers, which were delivered facing Mecca. Recent research paints a new picture of the debt that we owe to Arabic/Islamic mathematics. Certainly many of the ideas which were previously thought to have been brilliant new conceptions due to European mathematicians of the sixteenth, seventeenth and eighteenth centuries are now known to have been developed by Arabic/Islamic mathematicians around four centuries earlier. In many respects the mathematics studied today is far closer in style to that of the Arabic/Islamic contribution than to that of the Greeks. There is a widely held view that, after a brilliant period for mathematics when the Greeks laid the foundations for modern mathematics, there was a period of stagnation before the Europeans took over where the Greeks left off at the beginning of the sixteenth century. The common perception of the period of 1000 years or so between the ancient Greeks and the European Renaissance is that little happened in the world of mathematics except that some Arabic translations of Greek texts were made which preserved the Greek learning so that it was available to the Europeans at the beginning of the sixteenth century. That such views should be generally held is of no surprise. Many leading historians of mathematics have contributed to the perception by either omitting any mention of Arabic/Islamic mathematics in the historical development of the subject or with statements such as that made by Duhem in :- †¦ Arabic science only reproduced the teachings received from Greek science. Before we proceed it is worth trying to define the period that this article covers and give an overall description to cover the mathematicians who contributed. The period we cover is easy to describe: it stretches from the end of the eighth century to about the middle of the fifteenth century. Giving a description to cover the mathematicians who contributed, however, is much harder. The works and are on â€Å"Islamic mathematics†, similar to which uses the title the â€Å"Muslim contribution to mathematics†. Other authors try the description â€Å"Arabic mathematics†. However, certainly not all the mathematicians we wish to include were Muslims; some were Jews, some Christians, some of other faiths. Nor were all these mathematicians Arabs, but for convenience we will call our topic â€Å"Arab mathematics†. We should emphasize that the translations into Arabic at this time were made by scientists and mathematicians such as those named above, not by language experts ignorant of mathematics, and the need for the translations was stimulated by the most advanced research of the time. It is important to realize that the translating was not done for its own sake, but was done as part of the current research effort. Of Euclid's works, the Elements, the Data, the Optics, the Phaenomena, and On Divisions were translated. Of Archimedes' works only two – Sphere and Cylinder and Measurement of the Circle – are known to have been translated, but these were sufficient to stimulate independent researches from the 9th to the 15th century. On the other hand, virtually all of Apollonius's works were translated, and of Diophantus and Menelaus one book each, the Arithmetica and the Sphaerica, respectively, were translated into Arabic. Finally, the translation of Ptolemy's Almagest furnished important astronomical material. †¦ Diocles' treatise on mirrors, Theodosius's Spherics, Pappus's work on mechanics, Ptolemy's Planisphaerium, and Hypsicles' treatises on regular polyhedra (the so-called Books XIV and XV of Euclid's Elements) †¦ Perhaps one of the most significant advances made by Arabic mathematics began at this time with the work of al-Khwarizmi, namely the beginnings of algebra. It is important to understand just how significant this new idea was. It was a revolutionary ove away from the Greek concept of mathematics which was essentially geometry. Algebra was a unifying theory which allowed rational numbers, irrational numbers, geometrical magnitudes, etc. , to all is treated as â€Å"algebraic objects†. It gave mathematics a whole new development path so much broader in concept to that which had existed before, and provided a vehicle for future development of the subject. Another important aspect of the introduction of algebraic ideas was that it allowed mathematics to be applied to itself in a way which had not happened before. Al-Khwarizmi's successors undertook a systematic application of arithmetic to algebra, algebra to arithmetic, both to trigonometry, algebra to the Euclidean theory of numbers, algebra to geometry, and geometry to algebra. This was how the creation of polynomial algebra, combinatorial analysis, and numerical analysis, the numerical solution of equations, the new elementary theory of numbers, and the geometric construction of equations arose. Let us follow the development of algebra for a moment and look at al-Khwarizmi's successors. About forty years after al-Khwarizmi is the work of al-Mahani (born 820), who conceived the idea of reducing geometrical problems such as duplicating the cube to problems in algebra. Abu Kamil (born 850) forms an important link in the development of algebra between al-Khwarizmi and al-Karaji. Despite not using symbols, but writing powers of x in words, he had begun to understand what we would write in symbols as xn. xm = xm+n. Let us remark that symbols did not appear in Arabic mathematics until much later. Ibn al-Banna and al-Qalasadi used symbols in the 15th century and, although we do not know exactly when their use began, we know that symbols were used at least a century before this. Al-Karaji (born 953) is seen by many as the first person to completely free algebra from geometrical operations and to replace them with the arithmetical type of operations which are at the core of algebra today. He was first to define the monomials x, x2, x3, †¦ and 1/x, 1/x2, 1/x3, †¦ and to give rules for products of any two of these. He started a school of algebra which flourished for several hundreds of years. Al-Samawal, nearly 200 years later, was an important member of al-Karaji's school. Al-Samawal (born 1130) was the first to give the new topic of algebra a precise description when he wrote that it was concerned:- †¦ with operating on unknowns using all the arithmetical tools, in the same way as the arithmetician operates on the known. Omar Khayyam (born 1048) gave a complete classification of cubic equations with geometric solutions found by means of intersecting conic sections. Khayyam also wrote that he hoped to give a full description of the algebraic solution of cubic equations in a later work . If the opportunity arises and I can succeed, I shall give all these fourteen forms with all their branches and cases, and how to distinguish whatever is possible or impossible so that a paper, containing elements which are greatly useful in this art will be prepared. Sharaf al-Din al-Tusi (born 1135), although almost exactly the same age as al-Samawal, does not follow the general development that came through al-Karaji's school of algebra but rather follows Khayyam's application of algebra to geometry. He wrote a treatise on cubic equations. .. represents an essential contribution to another algebra which aimed to study curves by means of equations, thus inaugurating the beginning of algebraic geometry. Let us give other examples of the development of Arabic mathematics. Returning to the House of Wisdom in Baghdad in the 9th century, one mathematician who was educated there by the Banu Musa brothers was Thabit ibn Qurra (born 836). He made many contributions to mathematics, but let u s consider for the moment consider his contributions to number theory. He discovered a beautiful theorem which allowed pairs of amicable numbers to be found, that is two numbers such that each is the sum of the proper divisors of the other. Al-Baghdadi (born 980) looked at a slight variant of Thabit ibn Qurra's theorem, while al-Haytham (born 965) seems to have been the first to attempt to classify all even perfect numbers (numbers equal to the sum of their proper divisors) as those of the form 2k-1(2k – 1) where 2k – 1 is prime. Al-Haytham, is also the first person that we know to state Wilson's theorem, namely that if p is prime then 1+ (p-1)! is divisible by p. It is unclear whether he knew how to prove this result. It is called Wilson's theorem because of a comment made by Waring in 1770 that John Wilson had noticed the result. There is no evidence that John Wilson knew how to prove it and most certainly Waring did not. Lagrange gave the first proof in 1771 and it should be noticed that it is more than 750 years after al-Haytham before number theory surpasses this achievement of Arabic mathematics. Continuing the story of amicable numbers, from which we have taken a diversion, it is worth noting that they play a large role in Arabic mathematics. Al-Farisi (born 1260) gave a new proof of Thabit ibn Qurra's theorem, introducing important new ideas concerning factorisation and combinatorial methods. He also gave the pair of amicable numbers 17296, 18416 which have been attributed to Euler, but we know that these were known earlier than al-Farisi, perhaps even by Thabit ibn Qurra himself. Although outside our time range for Arabic mathematics in this article, it is worth noting that in the 17th century the Arabic mathematician Mohammed Baqir Yazdi gave the pair of amicable number 9,363,584 and 9,437,056 still many years before Euler's contribution. C. Arabian Mathematics/ Islamic Mathematics In  the  9th  century  Arab mathematician al-Khwarizmi wrote a systematic introduction to algebra, Kitab al-jabr w’al Muqabalah (Book of Restoring and Balancing). The English word algebra comes from al-jabr in the treatise’s title. Al-Khwarizmi’s algebra was founded on Brahmagupta’s work, which he duly credited, and showed the influence of Babylonian and Greek mathematics as well. A 12th-century Latin translation of al-Khwarizmi’s treatise was crucial for the later development of algebra in Europe. Al-Khwarizmi’s name is the source of the word algorithm. By  the  year  900  the  acquisition of past mathematics was complete, and Muslim scholars began to build on what they had acquired. Alhazen, an outstanding Arab scientist of the late 900s and early 1000s, produced algebraic solutions of quadratic and cubic equations. Al-Karaji in the 10th and early 11th century completed the algebra of polynomials (mathematical expressions that are the sum of a number of terms) of al-Khwarizmi. He included polynomials with an infinite number of terms. Later  scholars,  including 12th-century Persian mathematician Omar Khayyam, solved certain cubic equations geometrically by using conic sections. Arab astronomers contributed the tangent and cotangent to trigonometry. Geometers such as Ibrahim ibn Sinan in the 10th century continued Archimedes’s investigations of areas and volumes, and Kamal al-Din and others applied the theory of conic sections to solve problems in optics. Astronomer Nasir al-Din al-Tusi created the mathematical disciplines of plane and spherical trigonometry in the 13th century and was the first to treat trigonometry separately from astronomy. Finally, a number of Muslim mathematicians made important discoveries in the theory of numbers, while others explained a ariety of numerical methods for solving equations. Many  of  the  ancient  Greek works on mathematics were preserved during the middle Ages through Arabic translations and commentaries. Europe acquired much of this learning during the 12th century, when Greek and Arabic works were translated into Latin, then the written language of educated Europeans. These Arabic works, together with the Greek classics, were responsible for the growth of mathematics in the West during the late middle Ages.

This came from the title of a book, Hidab al-jabr wal-muqubala, written in Baghdad about 825 A. D. by the Arab mathematician Mohammed ibn-Musa al-Khowarizmi. The words jabr (JAH-ber) and muqubalah (moo-KAH-ba-lah) were used by al-Khowarizmi to designate two basic operations in solving equations. Jabr was to transpose subtracted terms to the other side of the equation. Muqubalah was to cancel like terms on opposite sides of the equation. In fact, the title has been translated to mean â€Å"science of restoration (or reunion) and opposition† or â€Å"science of transposition and cancellation† and â€Å"The Book of Completion and Cancellation† or â€Å"The Book of Restoration and Balancing. † Jabr is used in the step where x – 2 = 12 becomes x = 14. The left-side of the first equation, where x is lessened by 2, is â€Å"restored† or â€Å"completed† back to x in the second equation. Muqabalah takes us from x + y = y + 7 to x = 7 by â€Å"cancelling† or â€Å"balancing† the two sides of the equation. Eventually the muqabalah was left behind, and this type of math became known as algebra in many languages. It is interesting to note that the word al-jabr used non-mathematically made its way into Europe through the Moors of Spain. There an algebrista is a bonesetter, or â€Å"restorer† of bones. A barber of medieval times called himself an algebrista since barbers often did bone-setting and bloodletting on the side. Hence the red and white striped barber poles of today. II. Insights The Arabian contributions to Mathematics are much used around the world. Their Mathematics shows a perfect way to represent numbers and problems, in a way to make it clearer and easier to understand. They have discovered many things about mathematics and formulated many formulas that are widely used today. I learned from this research that Arabs mathematics started when Indian mathematics reached Baghdad and translated it into Arabic. They improved and studied Mathematics and formulated many things. They become more famous when they discovered Algebra and improved it. Many Arabian mathematicians became famous because of their contributions on Mathematics. Many ancient Greeks works on mathematics were preserved through Arabic translations and commentaries. I am enlightened about the origin of what are we studying now in Mathematics. Now I know that majority of our lessons in mathematics came from Arabians not from Greeks. I also learned that many mathematicians contributed on different branches and techniques on mathematics and it take so much time for them to explore and improve mathematics.

Al-Khwarizmi’s algebra was founded on Brahmagupta’s work, which he duly credited, and showed the influence of Babylonian and Greek mathematics as well. A 12th-century Latin translation of al-Khwarizmi’s treatise was crucial for the later development of algebra in Europe. Al-Khwarizmi’s name is the source of the word algorithm. By  the  year  900  the  acquisition of past mathematics was complete, and Muslim scholars began to build on what they had acquired. Alhazen, an outstanding Arab scientist of the late 900s and early 1000s, produced algebraic solutions of quadratic and cubic equations. Al-Karaji in the 10th and early 11th century completed the algebra of polynomials (mathematical expressions that are the sum of a number of terms) of al-Khwarizmi. He included polynomials with an infinite number of terms. Later  scholars,  including 12th-century Persian mathematician Omar Khayyam, solved certain cubic equations geometrically by using conic sections. Arab astronomers contributed the tangent and cotangent to trigonometry. Geometers such as Ibrahim ibn Sinan in the 10th century continued Archimedes’s investigations of areas and volumes, and Kamal al-Din and others applied the theory of conic sections to solve problems in optics. Astronomer Nasir al-Din al-Tusi created the mathematical disciplines of plane and spherical trigonometry in the 13th century and was the first to treat trigonometry separately from astronomy. Finally, a number of Muslim mathematicians made important discoveries in the theory of numbers, while others explained a ariety of numerical methods for solving equations. Many  of  the  ancient  Greek works on mathematics were preserved during the middle Ages through Arabic translations and commentaries. Europe acquired much of this learning during the 12th century, when Greek and Arabic works were translated into Latin, then the written language of educated Europeans. These Arabic works, together with the Greek classics, were responsible for the growth of mathematics in the West during the late middle Ages.

This came from the title of a book, Hidab al-jabr wal-muqubala, written in Baghdad about 825 A. D. by the Arab mathematician Mohammed ibn-Musa al-Khowarizmi. The words jabr (JAH-ber) and muqubalah (moo-KAH-ba-lah) were used by al-Khowarizmi to designate two basic operations in solving equations. Jabr was to transpose subtracted terms to the other side of the equation. Muqubalah was to cancel like terms on opposite sides of the equation. In fact, the title has been translated to mean â€Å"science of restoration (or reunion) and opposition† or â€Å"science of transposition and cancellation† and â€Å"The Book of Completion and Cancellation† or â€Å"The Book of Restoration and Balancing. † Jabr is used in the step where x – 2 = 12 becomes x = 14. The left-side of the first equation, where x is lessened by 2, is â€Å"restored† or â€Å"completed† back to x in the second equation. Muqabalah takes us from x + y = y + 7 to x = 7 by â€Å"cancelling† or â€Å"balancing† the two sides of the equation. Eventually the muqabalah was left behind, and this type of math became known as algebra in many languages. It is interesting to note that the word al-jabr used non-mathematically made its way into Europe through the Moors of Spain. There an algebrista is a bonesetter, or â€Å"restorer† of bones. A barber of medieval times called himself an algebrista since barbers often did bone-setting and bloodletting on the side. Hence the red and white striped barber poles of today. II. Insights The Arabian contributions to Mathematics are much used around the world. Their Mathematics shows a perfect way to represent numbers and problems, in a way to make it clearer and easier to understand. They have discovered many things about mathematics and formulated many formulas that are widely used today. I learned from this research that Arabs mathematics started when Indian mathematics reached Baghdad and translated it into Arabic. They improved and studied Mathematics and formulated many things. They become more famous when they discovered Algebra and improved it. Many Arabian mathematicians became famous because of their contributions on Mathematics. Many ancient Greeks works on mathematics were preserved through Arabic translations and commentaries. I am enlightened about the origin of what are we studying now in Mathematics. Now I know that majority of our lessons in mathematics came from Arabians not from Greeks. I also learned that many mathematicians contributed on different branches and techniques on mathematics and it take so much time for them to explore and improve mathematics.
