The Strategies and Appropriate Solution - Essay Example He also decided to include a major restructuring in the firm’s administration and its operational activities. Under these conditions, the appointment of David Michels, in 1991, as a chief executive should be considered as justified. The experience of David Michels in the particular industry (ex-Executive Vice President of Hilton International, Deputy Chief Executive of Hilton U.K.) made him the most appropriate candidate for the particular position. One of the priorities of David Michel has been to examine and evaluate the performance of the company for the last three years (1990-1992). The results of this research were disappointed showing a loss (after tax) of 47.4m pounds for the year 1992 and a relevant loss per share of 47.3m pounds for the same year. For this reason, David Mitchel stated that â€Å"It was worse than I thought. I didn’t know the company had quite as many difficulties as it had. I don’t think the company knew all its difficulties†. The above statement of David Mitchel could lead to the following thoughts: a) David Michel was not appropriately informed in advance of the firm’s financial difficulties. In this case, Sir Robertson could be considered as having the responsibility for the inadequacy and inaccuracy of the information provided; b) David Mitchel would not be able to respond to the firm’s needs. More specifically, his statements could be considered as showing his inability to resolve the problems that the firm had the specific period of time. Again the choice of Sir Robertson could be strongly doubted. On the other hand, the possible responsibility of David Mitchel could exist to the extension that he did not provide accurate information regarding his skills and his competencies in the particular field. As for the strategies followed by Reo Stakis and his son, these should be evaluated throughout the firm’s operation since its establishment in 1947 in Glasgow. The strategic leadership followed by Sir Lewis and David Michels led gradually to the recovery of the firm. It should be noticed that in January 1993 shares in Stakes reached the price of 45 pence (a 4 pence increase comparing the price of the share in 1992). Although Sir Lewis was replaced in late 1992, his style of leadership proved to be extremely positive for the firm’s performance in the long term (in 1994 the pre-tax profits were increased to 10.4 million). It is due to his decisions that the firm managed to recover and becoming in January 1994 â€Å"a normal company, boring even† according to a statement of David Michels.   

Dangers in the Environment Essay Example for Free

Dangers in the Environment Essay The Dangers within the Environment are affecting our health to means that we wouldn’t believe. We destroy our planets ozone that affects and causes global warming. The pesticides, mercury and carbon dioxide that we release into the environment cause so many health problems to use and our children. It actually affects our children’s health more than it does to use. How can we do this to our environment knowing that it affects our health more and more. Dangers with in our Environment The dangers within the environment that affect our health are increasing day by day. The first thing that is we are doing to the environment is destroying our ozone layer. We are destroying the ozone layer by greenhouse gases. The way we treat our planet is going to affect our health and maybe even kill us because of the toxins and pollutants that we release into our environment. Certain types of pollutants that we release into the environment can cause us to have several complications with our health. The pesticides, mercury and carbon dioxide that we release into the environment cause so many health problems to use and our children. It is not hard to see what we are doing to our planet on a daily basis. There is so much research that shows how much even low level of air pollution affects our health. Carbon dioxide is what we breathe out of our lungs when exhaling. Carbon dioxide is released while we are driving our motor vehicles, using our lawn mowers, and etc. For the one gallon of gasoline that is used in our machines it causes 19. of carbon dioxide to distribute into our environment. Trees absorb the carbon dioxide from the air but if the tree is cut down, burned, or dies then the carbon dioxide will not be absorbed up. When a tree slowly rots then the carbon dioxide is slowly released back into the environment. The pesticides that are toxic to our health and our environment are chemical pesticides. The chemical pesticides that is more dangerous to be farmers, their family members, and other people who use the chemical pesticides. The pesticides are released into the air that we breathe in. The pesticides are left on the produce that they are sprayed on and then remain on the inside of the produce. The pesticides can be rinsed off, but they also can run off into springs, and large bodies of water. In which the pesticides can contaminate our water supply. In the world today everyone is at risk for simple reason that we are destroying our planet. Our world is at a total disaster at how we treat it and take care of it. Individuals that live in the world are at risk form pollutants and toxins that are in the environment that we breathe on a daily basis. The pesticides, mercury and carbon dioxide that we release into the environment cause so many health problems to use and our children. We need to take better care of our environment and worry about our health. People do not care about their health because if they did then they will not smoke cigarettes that affect their health and our environment. If we would save from driving all over the place in our vehicles when you could ride a bike or walk. It could help save our environment from pollutants being disbursed into the air that we breathe.

Mankind Is The Earths Biggest Threat Environmental Sciences Essay

Mankind Is The Earths Biggest Threat Environmental Sciences Essay Climate change brought about by global warming is one of the biggest threats to mankinds survival. Due to human activity the temperature of the earths surface has increased by about 1.4 °F during the last 90-100 years. Scientists have identified that greenhouse gases are the main reason we are experiencing global warming. The last government was attempting to combat climate change by setting annual targets for the reduction of carbon dioxide emissions until 2050 by placing duties on the Prime Minister regarding the reporting on and achievement of those targets; to specify procedures to be followed if the targets are not met; to specify certain functions of and provide certain powers to Members of Parliament with regard to ensuring carbon dioxide emissions are reduced and to set sectored reduction targets and targets for energy efficiency. This seems very easy in principal but in reality the government has failed since the Kyoto Protocol. One key area where they are failing is in th e housing sector as the aims are primarily focused on new homes rather than the existing housing stock. By the year 2050 there will be 21 million homes in need of an upgrade to reduce the carbon emissions being released into the atmosphere. In this dissertation we will examine the reasons for global warming and climate change, what government initiatives have been introduced and what solutions can, have and will be implemented to reduce carbon emissions with an emphasis on renewable technologies. Declaration I declare that the work contained in this dissertation is my own original work and that no part has been plagiarised from any source whatsoever. Where work, ideas or concepts have been taken or adapted from authors, these will be properly cited and referenced. This dissertation is approximately 10000 words in length.

Introduction Aim Objectives Research Methodology Literature Review Global Warming and Climate Change Energy Use Background to climate change mitigation The Kyoto Protocol European union context United Kingdom Context EU Directive Alternative and Renewable Energy Ground Source Heat Pumps Biomass Energy Solar Energy Types of Systems 5.1(a) Solar Hot Water Systems 5.1(b) Photovoltaics 6. Micro Combined Heat Power 7. Wind Energy Technology Introduction The government and industry must reduce their carbon emissions from the United Kingdoms domestic sector in order to meet their climate change targets. 30% of all the United Kingdoms energy comes from the domestic sector and in turn accounts 45% of all emissions. (2008 Energy Technologies Institute LLP-Part of the low carbon innovation group). By the year 2050 there will be approximately 32 million dwellings of which 21 million will require refurbishment as they will be the existing housing stock. The government have set a target of an 80% reduction in carbon emissions by 2050 and in order to achieve this goal they will have to install insulation, educate householders on ways to use energy more efficiently, use more low energy products and supply energy from renewable sources. Aim The main aim of this study is to examine ways to reduce carbon emissions from the United Kingdoms existing housing stock. Objectives The main objectives of this study to examine: A brief history of global warming and climate change What government legislation is in place to reduce carbon emissions The current energy efficiency of the United Kingdoms existing housing stock What contribution renewable energy can make towards reducing carbon emissions Research methodology The objectives outlined previously will give the reader a better understanding of the subject areas. The research carried out will be a 50 50 split between qualitative and quantitative research. Qualitative research is subjective in nature. It is research that cannot be measured because it is not based on facts. It is based on people beliefs, their feelings and their own personal opinions and experiences. (Naoum 2007 second edition) Quantitative research is objective in nature. It is research that is based on factual information that can be proven. It could be results from tests, surveys etc that can be analysed. (Naoum 2007 second edition) Primary literature is research that includes academic journal, published original work and technical papers. AND secondary literature sources are sources such as text books and newspaper articles ((Naoum 2007 second edition) Dissertation Structure The research into my aim and objective will provide a greater depth of understanding of each subject area. The study will give a background into the need for an energy efficient housing stock including looking at reasons for global warming and climate change. It will also discuss government initiatives and energy use in the domestic sector as well as the reasons why it is difficult to achieve the aims. The existing housing stock will be researched to ascertain their energy efficiency before and after refurbishment. Some of the primary literature I plan to use include; Kyoto Protocol to the United Nations Framework Convention on Climate Change The EUs Contribution to Shaping A Future Global Climate Change Regime The Sixth Environment Action Programme of the European Community 2002-2012 Our Energy Future Creating a Low Carbon Economy Action in the UK The UK Climate Change Programme European Buildings Directive Met office action on co2 Planning for micro renewables Renewable energy technologies, Scottish Executive, Development Department HM Government- Renewable Energy Strategy Some of the Secondary Sources I plan to use include; Environmental science in buildings 6th Edition (Randall McMullan) CIBSE Energy and carbon emissions regulations A guide to implementation The scope for reducing carbon emissions from housing (J.Henderson L. Shorrock) Literature Review Global warming and Climate Change People are the main cause of climate change. 40% of all co2 emissions come from greenhouse gases such as carbon dioxide and methane through energy use in the home, driving and air travel. Global climate change occurs naturally through oceans, changes in the earths orbit and the suns energy but there is evidence that the greenhouse effect is made worse by mans actions. What changes have been observed? global temperature increase: +0.75 °C over the past century with 2000-2010 the warmest decade on record rainfall patterns: wet regions of the world are getting wetter, and dry regions getting drier humidity: increases over the last  two to three  decades make extreme rainfall and flooding more likely warming oceans: temperature increases in the last 50 years in the Atlantic, Pacific and Indian oceans are not linked natural variations salinity: increased evaporation is making the Atlantic saltier in sub-tropical latitudes sea-ice: summer Arctic sea-ice is declining by 600,000 km ² per decade (the area of Madagascar), a long-term trend only explicable by human influences How the evidence stacks up Scientists have used sophisticated methods to identify these long-term changes, and to then consider: are these changes due to natural variability? (changes in energy from the sun, volcanic eruptions, or natural cycles such as El Nià ±o) if not, is there evidence that human activity could be to blame? Peter Stott, Head of Climate Monitoring and Attribution at the Met Office, said: The science reveals a consistent picture of global change that clearly bears the fingerprint of man-made greenhouse gas emissions. This shows the evidence of climate change has gone beyond temperature increases   it is now visible across our climate system and all regions of the planet. The average person thinks that the weather and climate change are the same but this is not the case. Weather is rain, hail, sleet, snow and wind with varying temperatures that change daily, where as climate change is a study of the weather and it changes over time. The greenhouse consequence is the natural process of the earths atmosphere allowing in some of the energy we receive from the sun (ultraviolet and visible light) and stopping it being transmitted back out into space (infrared radiation the greenhouse effect is the natural process. This makes the Earth warm enough for people to live. Although there have been quite stable levels of greenhouse gases for many years, industrial and domestic energy use has upset the balance with the evidence of climate change now being seen right across the planet with temperature increases and melting ice caps causing havoc with our eco-system. Energy Use Humans use energy such as coal, gas and oil everyday and everytime they do so carbon monoxide and other gases are absorbed by the atmosphere. The natural cycle was for the carbon dioxide to be reabsorbed by the plants and trees. However, we are burning so much fuel, and with humans cutting down our rainforests. the trees and plants can no longer cope. As the increased carbon dioxide levels rise they are being trapped within our atmosphere causing the temperature to rise. This is global warming. As the global temperature is rising daily we are seeing more floods and extreme weather such as tornados and hurricanes. To try to combat this we have to reduce the amount of fossil fuels we are using. (The Carbon

Basic Telescope Physical and Optical Characteristics Essay -- physics

Here you will find a variety of information on the optical characteristics of various types of telescopes as well as some of the basic underlying physics behind them. This includes some information that pertains to the preformance degredation of a telescope optical system (for instance, vignetting and air turbulance) and a few concepts of mirror design (the parabolic shape and over/under correction of the primary mirror). I'd recommend starting with the "Optical Paths" section so you can familiarize yourself with some of the basic types and concepts of several of the widely used telescope designs before reading the other sections. Optical Paths of Various Types of Telescopes Here is one of the most interesting parts of astronomy and star gazing: the equipment. There are four different types of basic telescope designs that are in use today. One of these, perhaps the most widely known, is the Refractor. The refracting telescope was first utilized for astronomy by Galileo Galilei in 1609, but it was invented by the German Dutch lens maker named Hans Lippershey in 1608 (Zoom Inventors and Inventions). There are also three other types of common telescopes. These include the Shmidt Cassegrain, Maksutov Cassegrain, and the Newtonian Reflector. In terms of design, they all have different advantages and disadvantages (including cost considerations) that have to be taken into account if one were to decide on a particular design to purchase. Ultimately, the physics behind the the different designs will have an effect in influencing a purchasing decision. But before the four different designs are discussed with greater detail, a few technical terms must be introduce d and defined.

Key Messages Of The National Education Policy Education Essay

Explain what challenges you think you might confront as a get downing instructor in trying to implement the National Education policy enterprise. National Education ( NE ) was introduced to Singapore Schools in 1997 to develop national coherence, cultivate the inherent aptitude for endurance as a state and instil in our pupils, assurance in our state ‘s hereafter. It besides emphasises on cultivating a sense of belonging and emotional rootedness to Singapore. Many programmes such as Community Involvement Programme ( CIP ) and Learning Journeys were designed to assist schools accomplish such aims and the duty of put to deathing these programmes falls on the instructors. As a beginning instructor, freshly introduced into the profession, challenges are faced in the effort to implement such enterprises. In my sentiment, one major challenge that I would meet is planing activities that infuses a sense of relevance in our pupils – allowing them understand that national coherence is a consequence of the uninterrupted attempts of every Singaporean, and they are a portion of the equation. These pupils were born in the epoch of political and economical stableness, where bulk grew up in environments run intoing their demands and carry throughing most of their wants. Hence, they have the inclination to take their security and wellbeing for granted, doing them unable to grok the battles faced by Singapore in keeping the current success and stableness and the demand for NE. For illustration, most schools in Singapore commemorate nucleus event, Racial Harmony Day through the showcasing of the diversified cultural costumes and playing of cultural games to enable their pupils ‘ in-depth cultural cognition of their equals. Yet, a bulk of them treat the recollection of the twenty-four hours as an chance for an interesting concert and a half-day school, and few genuinely understanding the implicit in principle behind the activities, allow entirely instil a sense of relevance. Amidst the current racial harmonious atmosphere between different racial groups, pupils are unable to gestate the thought of racial public violences, its ‘ impact on Singapore and the importance of racial harmoniousness in a society. They view information relayed through these events as irrelevant and doubt the possibility of the return of such incidents in the current Singapore. It is of a common apprehension that the six NE messages would ever stay as words on paper unless instructors inculcate them into pupils in an piquant mode. Therefore, as a get downing instructor with no anterior experience in the ingraining of NE messages, I feel that the undertaking of planing engaging, merriment and relevant activities would be enormous, with myself holding unequal cognition of the activity thoughts that pupils are receptive to. Instilling a sense of relevance in pupils would be a immense challenge as it is non an easy undertaking to alter pupils ‘ deeply-rooted thought from â€Å" the duty of keeping national coherence autumn merely on the grownups and authorities † to the thought that â€Å" national coherence is the duty of everyone, including pupils † . Students should be taught that societal coherence occurs because each and everyone put in attempt and play our portion in lending to the wellbeing of the state. The issue is relevant to both grownups and pupils. From my personal observation, about all Singapore Schools repeat the same NE programmes for their pupils every twelvemonth, differing merely at the activities to be completed at single degrees. As such, pupils were bored of it, and older pupils particularly, expressed cynicism, and were unresponsive to the programmes. Hence, I feel that the 2nd challenge that I would confront as a get downing instructor in the effort to put to death the enterprises is eliciting pupils ‘ involvement in the engagement of NE-related activities. Unlike the traditional topics that we were taught to learn in the instruction institute, NE is non merely another topic where pupils learn by conventional instruction methods. In fact, pupils understand the constructs in NE better when the activities are prosecuting, merriment and capture their attending. Although pupils reflected that programmes designed by the school ‘s NE commission were everyday, get downing instructors, including myself, are unable to plan and implement new thoughts in topographic point of old 1s, with bing NE models in schools. On the contrary, I would be expected to follow the guidelines and present a similar NE lesson. As a get downing instructor with limited learning experience and teaching methods accomplishments, I would miss the ability in transform these guidelines into prosecuting and interesting lessons on par as that of the experient instructors. Most experient instructors are able to present interesting NE lessons, transforming the repetitive, dull lesson into prosecuting sharing lessons while staying by the guidelines. They reflected on their past instruction experiences, gathered feedback from old batches of pupils, and modified their instruction teaching method consequently to appeal to pupils ‘ involvement. Therefore, pupils ‘ involvements in NE activities are aroused and they participate actively in it. On the other manus, get downing instructors enter schoolrooms today with high outlooks of ourselves and of our pupils. Our learning method would be influenced by single background and assorted learning theories. However, the deficiency of experience in the instruction field would impact the quality of the lesson bringing as I would be unable to accommodate to pupils ‘ demands. In add-on, I would be given to avoid diverting from the model to plan newer, more exciting lessons as I fear for botching the ba lance between merriment and content. After all, the intent of the NE lesson would be defeated if there is more merriment than content. To reason, the aims of NE could be attained through appropriate programmes and it is therefore highly of import to instill a sense of relevance in our pupils and to elicit their involvement in NE activities. When faced with challenges in the effort to implement the policies, get downing instructors should detect, persevere and seek for aid to get the better of them. Through these challenges, we would turn to go better pedagogues and in bend, supply the greatest benefits to the pupils.

Could Cannabis Cure Professor Ramos Blog

Could Cannabis Cure FDA Approves CBD Drug Epidiolex This video titled â€Å"FDA Approves CBD Drug Epidiolex† by Dean, from the YouTube channel called CBD School, was very informational and easy to understand and I gave it 8 out of 10 stars. It informs the viewer that a new cannabidiol (CBD) based medicine derived from the marijuana plant called Epidiolex was just approved by the FDA. It was developed by GW Pharmaceuticals to mainly treat two rare forms of epilepsy, Lennox-Gastaut syndrome and Dravet syndrome. These two types of epilepsy are frequently resistant to treatment yet cannabidiol has been showing promising signs for treatment. This approval will help not only the patients with this condition but also the cannabidiol industry as well to get more credible in the modern world of medicine. This video gave enough information for anyone to get a grasp of the main idea so then after it they could even watch more videos he has made or go look to the research itself. His demeanor was a little bit stiff yet he spoke clearly. He tried to repeat his topics so that we would not forget them during the middle of it which was helpful as well as talked about other cannabis products to plug his other videos into this one. That was a smart move because then you want to continue watching. Again, this video was 8 out of 10 stars and the only reason it got two below perfect was that it didn’t explain the scheduling for the DEA that much or about cannabidiol itself. So in addition to this video, here is some information I have gathered to piece the video together a bit more for those who don’t quite understand everything he is saying. First I want to explain what epilepsy is for those who have never heard of it or know very little about it. In an article about cannabidiol and epilepsy it defines epilepsy as, â€Å"uncontrolled seizures, which can be associated with poor quality of life and mental illness† which effects roughly 50 million people worldwide (Ali, Scheffer Sadleir 1). Yet as Ali et al. states, â€Å"The most severe group of childhood epilepsies are the developmental and epileptic encephalopathies (DEEs)†¦ devastating disorders are defined by frequent seizures and epileptiform abnormalities that result in severe cognitive and behavioral impairment† with about 24% of them dying within 20 years of being diagnosed (1). Dravet syndrome is a prototypic DEE so it stems from the more severe group of epilepsies which makes it harder to treat with regular antiepileptic drugs. In the results of one of the main studies of Epidiolex that was approved by the FDA reveals that, â€Å"This randomi zed, controlled trial showed that cannabidiol resulted in a greater reduction in convulsive seizure frequency than placebo among children and young adults with drug-resistant Dravet syndrome† (Devinsky, Ottin, et al., 2018). This is great news because it shows that these drug resistant syndromes have a weakness. Also, it is the small victories with cannabidiol that could lead to the rescheduling of this plant so we can find other medicinal ways that it could help the world. Now since the cannabis plant is still considered a Schedule One drug it was hard to get the FDA, let alone the DEA, to approve any medicine that was derived from this plant. What a does it mean to be a Schedule One drug? Well on the DEA website it states, â€Å"Schedule I drugs, substances, or chemicals are defined as drugs with no currently accepted medical use and a high potential for abuse. Some examples of Schedule I drugs are: heroin, lysergic acid diethylamide (LSD), marijuana (cannabis), 3,4-methylenedioxymethamphetamine (ecstasy), methaqualone, and peyote†. With the studies that have been proving that the cannabis plant has medicinal values it was only a matter of time before the FDA and DEA had to reconsider this scheduling. For those who do not know what cannabidiol is, let me give you a little background information. In an article about the safety and side effects of cannabidiol it states, â€Å"In contrast to D9-THC, it is nonintoxicating, but exerts a number of beneficial pharmacological effects. For instance, it is anxiolytic, anti-inflammatory, antiemetic, and antipsychotic. Moreover, neuroprotective properties have been shown†¦ could be used at high doses for the treatment of a variety of conditions ranging in psychiatric disorders such as schizophrenia and dementia, as well as diabetes and nausea† (Iffland Franjo 139) In other words, cannabidiol has been shown to have medically beneficial properties as well as being non-psychoactive. What that means is that unlike the tetrahydrocannabinol, THC, it does not get you â€Å"high†. Regarding this information it is easy to see why to most want to utilize this part of the cannabis plant for its medicinal purposes and why GW Pharmaceu ticals did just that. On their website it states, â€Å"GW has established a world leading position in the development of plant-derived cannabinoid therapeutics through its proven drug discovery and development processes, intellectual property portfolio and regulatory and manufacturing expertise†¦was founded in 1998 and is listed on the NASDAQ Global Market (GWPH). The company has operations in both the US and the UK†. With this company gaining recognition, I hope to see more products from them that could be used by others without epilepsy as well. Hopefully videos like this will help to keep spreading the word about all the medically beneficial ways that cannabis can help the world. That is another reason why I gave it such a high rating. Usually when you watch videos about cannabis, the person in it could be intoxicated from the THC and may not get to the point they are trying to make. In regards to this one I think he set a great example of how informational videos about cannabis should be. Easy to hear and easy to understand. Thanks Dean for the info!

Battle regarding evolution in public schools Essays

Battle regarding evolution in public schools Essays Battle regarding evolution in public schools Essay Battle regarding evolution in public schools Essay Essay Topic: The School for Scandal Many groups have tried to force their thoughts on the populace through schooling. Public school pupils, totaling in the 1000000s, seem a perfect, confined audience for the announcement of the thoughts of a few holier-than-thou groups. These groups have tried to act upon national thought by advancing their positions in the schoolroom, but this is non an acceptable method. A public school schoolroom is a topographic point for the passing of recognized cognition from an teacher to a pupil, non the topographic point for the thoughts of the nescient few to act upon the thought of the many. The local and province school boards serve as the cheque on the vocal few and find the course of study to be administered to the multitudes of pupils go toing category. Current scientific discipline course of study is widely accepted. Parents and communities have no ailments over their pupils larning about the categorization of animate beings and workss, chemical science, gravitation, cells, and organic structure procedures. The ailments are focused around the instruction of development, but for the many educated people in the field of biological science, development is a basic rule. Public school pupils must be exposed to this cardinal construct and be familiar with it. Evolution must be taught in schools since it is a scientific theoretical account that can non and should non be ignored. All other alternatives-creation scientific discipline, intelligent design, creationism, and others-are spiritual and have no topographic point in the public school schoolroom. Looking at the histor ical case in point and scientific credence, development is the lone theoretical account of life beginnings and patterned advance that should be taught in public schools. The conflict sing development in public schools has been traveling on for over a century. Charles Darwin published his book On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life in 1859. The conflict in the American tribunals over his thoughts being taught in school did non get down until after the bend of the century, nevertheless. The jobs began when fundamentalist Christians, or creationists, began to worry as they saw the figure of high school pupils explode to over two million between 1900 and 1920. [ 1 ] Darwin s evolutionary thoughts were now making more pupils than of all time. The Christians decided they needed to beef up their place in schools and initiated measures in several provinces to mandate the already present patterns of supplication and Bible reading. Along with these measures came antievolution Torahs. 1923 saw the first of a long line of measures doing it illegal to learn development in public schools. Ohio started things off with their measure that banned public school text editions that taught Darwinism. Florida s declaration of that same twelvemonth stated that it was improper and insurgent for public schools to Teach as true Darwinism or any hypothesis that links adult male in blood relationship to any signifier of lower life. [ 2 ] Tennessee followed suit in March 1925 when their le gislative assembly stated that it shall be improper for any instructor in any of the Universities, Conventions and all other public schools of the State which are supported in whole or in portion by the public school financess of the State, to learn any theory that denies the narrative of the Divine Creation of adult male as taught in the Bible, and to learn alternatively that adult male has descended from a lower order of animate beings. [ 3 ] Textbook publishing houses began to fear a diminution in gross revenues get downing about this clip and began to revise their editions to take all mentions to development and Darwinism. [ 4 ] Fundamentalist Christians had won their first conflict as the instruction of development was stunted across the state. Three provinces passed new antievolution statute law between 1925 and 1930 and by the 1930s, fundamentalist fastnesss in the South had established some signifier of antievolutionary policy, whether school board mandates or administrative opinions. [ 5 ] The antievolutionary feelings had spread, much to the hurt of scientific acquisition. Evolution shortly became forbidden in the public schools. Through the 1940s, instructors and decision makers worried about piquing parents and communities and therefore avoided the instruction of development. Textbooks continued to go forth out evolutionary thoughts. It was estimated that less than half of all high school scientific discipline instructors in the early 1940s taught anything about development. [ 6 ] 1947 marked the beginning of the terminal for fundamentalist Christians contending the war over development. The United States Supreme Court ruled that neither a province nor the federal authorities could go through any statute law aiding or giving penchant to a faith. The fundamentalists took another blow in 1948 in McCollum vs. Board of Education. The Court stated that Illinois affords sectarian groups an priceless assistance in that it helps to supply students for their spiritual categories through usage of the province s mandatory public school machinery. This is non separation of church and province. [ 7 ] This ended all spiritual direction in public schools. The Space Race of the 1950s spurred new ardor in scientific discipline instruction. Scientists and politicians likewise pushed for new biological science text editions, conveying development back to the schoolroom. Fundamentalists that had triumphed in the first one-fourth century were losing the war over development, conflict after conflict. After supplication and Bible reading were eliminated from the schoolroom in 1962 and 1963, development itself eventually made it to the Supreme Court in 1968. The new push for greater scientific discipline instruction triggered by Sputnik ran into a wall of antievolution Torahs. These Torahs prevented the enlargement of scientific, chiefly biological, cognition and new findings into the schoolroom. The instructor s brotherhood in Arkansas challenged the province jurisprudence and appealed the opinions until their instance landed in the Supreme Court. The Court found the Arkansas antievolution jurisprudence to be unconstitutional. [ 8 ] This efficaciously ended all Torahs forestalling development from being taught in public schools. Another loss for fundamentalists and a immense addition for pupils and scientific discipline. The creationists had been defeated repeatedly in the tribunals and could merely acquire their positions back in the schoolroom with a large interruption. Much to the irritation of the scientific community, this interruption came in the eightiess with the rise of equal clip measures. The fundamentalists were still smartly seeking to barricade the instruction of evolutionary biological science in the schools, or if that proved impossible, to demand equal clip for the instruction of creation scientific discipline, which was an effort to flex scientific informations to conform to one of the scriptural histories of creative activity and throw uncertainty on the finds of evolutionists. [ 9 ] In 1982, nevertheless, McLean vs. Arkansas Board of Education put an terminal to the creative activity scientific discipline effort though. A federal tribunal ruled that creative activity scientific discipline is non a scientific discipline at all, but a spiritual belief, and therefore non allowed in public school schoolrooms. [ 10 ] Another measure, passed in Louisiana in 1981, went to the Supreme Court in 1987, giving the Court an chance to reenforce the place against creative activity scientific discipline. The determination states that Louisiana s equal clip Act impermissibly endorses faith by progressing the spiritual belief that a supernatural being created world The Act s primary intent was to alter the public school scientific discipline course of study to supply persuasive advantage to a peculiar spiritual philosophy that rejects the factual footing of development in its entireness. Therefore, the Act is designed either to advance the theory of creative activity scientific discipline that embodies a peculiar spiritual dogma or to forbid the instruction of a scientific theory disfavored by certain spiritual religious orders. In either instance, the Act violates the First Amendment. [ 11 ] Creationists were unrelenting though. If they could non convey their ain version of the beginning and development of life into the schoolroom, they would seek their hardest to discredit development. In the mid-1990s, the thought of text edition disclaimers took clasp, particularly in the South. The Alabama State Board of Education voted in 1995 to necessitate an absurd one-page disclaimer to be pasted into every new biological science text edition. The disclaimer began, This text edition discusses development, a controversial theory some scientists present as a scientific account for the beginning of life things, such as workss, animate beings and worlds. No 1 was present when life foremost appeared on Earth. Therefore, any statement about life s beginnings should be considered as theory, non fact. [ 12 ] In 1994, the Tangipahoa Parish Board of Education in Louisiana required that the undermentioned disclaimer be read before the beginning of any lesson sing development: It is hereby recognized by the Tangipahoa Parish Board of Education, that the lesson to be presented, sing the beginning of life and affair, is known as the Scientific Theory of Evolution and should be presented to inform pupils of the scientific construct and non intended to act upon or deter the Biblical version of Creation or any other construct. It is farther recognized by the Board of Education that it is the basic right and privilege of each pupil to organize his/her ain sentiment or keep beliefs taught by parents on this really of import affair of the beginning of life and affair. Students are urged to exert critical thought and garner all information possible and closely examine each alternate toward organizing an sentiment. [ 13 ] The tribunals found these statements unacceptable. The National Science Teachers Association ( NSTA ) adopted as portion of their place on the instruction of development in 1997 that [ s ] cience text editions shall stress development as a consolidative construct. Publishers should non be required or volunteer to include disclaimers in text editions refering the nature and survey of development. [ 14 ] Thankfully, textbooks no longer come with a sacredly based spine that undermines the credibleness of development. Creationists have non given up-the contention continues today. In 1999, the Kansas State Board of Education voted to replace development, the large knock, and any mentions to an earth one million millions of old ages old with the Intelligent Design theory. Fortunately, this determination was overturned in 2001 when a new Board was elected. [ 15 ] Unfortunately, Kansas is non the lone province covering ill with development though. A national survey done by the Fordham Foundation in 2000 found that 12 provinces had useless or absent instruction of development, but Kansas was given the lone F- for making a scandalous occupation. [ 16 ] As one can see, the history of development in schools is disruptive. Different groups within the fundamentalist motion have tried, and failed, to set faith in schools. Since all options to development are sacredly based, they can non be included in the course of study. It seems clear though that development is the lone option that can lawfully be taught in schools. Throughout the conflict in the tribunals, the creationists have failed to understand what scientific discipline truly is. Harmonizing to Webster s lexicon, scientific discipline is cognition or a system of cognition covering general truths or the operation of general Torahs. [ 17 ] Evolution falls absolutely into this class. Evolutionary biological science is a cardinal scientific theory that provides a all right instance history of how scientific discipline is done. [ 18 ] It is non a topic that can be ignored and pupils must be exposed to it in school. In fact, it is important to the apprehension of many biological constructs and must be referred to throughout the course of study, which should reflect and learn scientific cognition, non the specific beliefs of an involvement group or organisation. Since scientific discipline is neither a spiritual dogma nor a portion of a belief system, one can non believe in development. Evolution is non a spiritual belief or credo. [ 19 ] One can, and should, accept the rule as scientifically accurate, but it is non something one can believe in or non. This is different from creative activity scientific discipline. Creation scientific discipline is non a scientific theoretical account because of its trust on the supernatural. It steps outside the scientific kingdom with its thoughts that are non of the natural universe itself. Foundations of Biology, a text edition from 1953, explains the scientific rejection of creationism this manner, the particular creative activity theory as a actual account of the life universe is non accepted as a sound biologic rule by most life scientists. Credence of this theory would virtually shut the door to farther research. [ 20 ] Besides, since the constructs of creative activity scientific discipline ca n non be seen or tested since they are based on scriptural histories, they do non fall into the field of scientific discipline. As stated in the National Science Education Standards and supported by the National Science Teacher s Association, accounts on how the natural universe alterations based on myths, personal beliefs, spiritual values, mystical inspiration, superstitious notion, or authorization may be personally utile and socially relevant, but they are non scientific. [ 21 ] Evolution, on the other manus, is based on discernible, testable grounds found in nature. Development is clearly scientific and has and will go on to be tested in assorted subjects and countries of survey. The occupation of the scientific discipline instructor is to supply the pupil with a full instruction of all scientific rules. Development is one of these rules, and a really of import one at that. Eugenie C. Scott, the executive manager of the National Center for Science Education put it this manner: The occupation of a scientific discipline instructor is to learn province of the art scientific discipline, and that means development. Students who do non understand development can non be said to be scientifically literate. [ 22 ] The NSTA supports the place that development is a major uniting construct of scientific discipline and should be included as portion of K-College scientific discipline models and course of study. [ 23 ] Pennsylvania s Academic Standards for Science and Technology adopted in 2002 concur. The province s Department of Education includes evolutionary constructs and theory as portion of the criterions that depict what pupils should cognize and be able to m ake by the terminal of 4th, 7th, 10th and 12th class. [ 24 ] The National Science Education Standards besides include development as a cardinal subject in life scientific discipline and biological science. The 9-12 class content criterions include the fact that natural choice and its evolutionary effects provide a scientific account for the dodo record of ancient life signifiers, every bit good as for the dramatic molecular similarities observed among the diverse species of life beings. [ 25 ] Textbooks from throughout the century, when they were lawfully allowed, devoted big subdivisions to development. General Biology from 1928 says, the development of life things is to the trained life scientist an established fact. To him the grounds in support of such a belief is every bit convincing as that underlying the phenomena of gravity and chemical affinity. [ 26 ] The text edition exhaustively explains the major facets of development theory and even explores controversial human de velopment. As one can see, legion organisations believe that pupils should be exposed to the best scientific cognition in biological science, every bit good as in all Fieldss of their instruction. Public school pupils need to larn the positions of modern scientists, non scriptural literalists. The National Academy of Sciences provinces that [ s ] cientists every bit good as pedagogues have concluded that evolution-and merely evolution-should be taught in scientific discipline categories because it is the lone scientific account for why the existence is the manner it is today. [ 27 ] The creationists are non satisfied with scientists and scientific organisations publicity of development. They merely do non believe that development in true. This is a immense false belief, but they use the theory versus fact statement to deny development s credibleness. They say that since it is called the Theory of Evolution it is non proven true and hence should non be taught in schools. The scientific community, nevertheless, disagrees. John A. Moore, Professor of Biology at the University of California, Riverside and textbook writer explains in his book Science as a Way of Knowing, The Foundations of Modern Biology, theory for a scientist may stand for the grandest synthesis of a big and of import organic structure of information about some related group of natural phenomena. [ 28 ] The scientific community accepts a theory as true after extended and thorough testing and experimentation. Theories are alterable with new grounds though. If parts of Darwin s expansive theor y of development are found to be false, the theory itself will non be tossed out. Those parts will merely be eliminated or replaced by more accurate or likely informations. General theories are neer disproved, merely improved, says Professor Moore. [ 29 ] The NSTA agrees. They say, [ T ] heories and other accounts change as [ the ] organic structure of scientific cognition alterations [ with ] new observations and finds. [ 30 ] Development can be a confusing topic, but [ m ] any misconceptions about the procedure of natural choice can be changed through direction. [ 31 ] The instructor needs to show the facts and guide pupils into accepting the truth that the grounds shows. The dodo and anatomical record grounds for consecutive alterations of the workss and animate beings through geologic clip, with more complex signifiers looking subsequently, is so overpowering that all one demands is to hold pupils analyze the facts. [ 32 ] This is non where the conversation sing development should stop, nevertheless. Teachers have to cover with the contention every bit good. When discoursing controversial issues such as development, normally it is non the facts under consideration that are controversial ; these are by and large good established. It is the reading of the facts for personal behaviour which may be controversial. [ 33 ] This helpful testimony was shared with instructors in the 1958 edition of a ushe r for learning high school scientific discipline called A Book of Methods. It goes on to state that much is gained by promoting pupils to talk out in expostulation to evolution and so patiently pulling from them the statement that the rule of development is what life scientists have developed as an account of the facts at manus. [ 34 ] Teachers can non anticipate to learn the topic with no expostulations and no inquiries. The pupils will all convey their personal values and beliefs with them to category and particularly sing development, will be really defensive of them. The instructor should explicate why lone development is taught and why options to evolution, including creative activity scientific discipline and intelligent design, are non presented. These options are non to be presented in category because they, and all other options, are sacredly based. Based on the case in point set by the Supreme Court, none of these religiously based theoretical accounts can be allowe d into the public school schoolroom. Development is doubtless indispensable to a complete apprehension of scientific discipline. Students will non hold a full position of the scientific universe if they do non larn development. But faith besides has its topographic point in society. It should non be ignored or silenced, but it merely can non be allowed into the sphere of the public school schoolroom. Religious thoughts and survey should be accepted for what they are, but they are non science. Teachers of scientific discipline can non convey alternate theoretical accounts of the patterned advance of life into the schoolroom. Some may experience that by making this, we deny pupils their academic freedom, but this is non so. They are free to research as much of creationism or intelligent design as they desire, but non in school. We can non deny our pupils the chance to larn the scientific findings about the astonishing patterned advance of life that has taken topographic point on this planet.

Stress-Related Illness Essay Example | Topics and Well Written Essays - 1500 words

Stress-Related Illness - Essay Example As the discussion stresses the school owners and directress have entrusted Kelly with the role of training new teachers with the quality of teaching she is known for. She is likewise head of the Parent Involvement Program of the school. Her many duties at work, on top of preparing for her own preschool class and her homemaker role at home has been taking its toll on Kelly. For the past month, she has complained of recurrent migraines, stomach pains and general body malaise. Generally, stress is what one feels when the demands on his life exceed his ability to meet those demands. The stressor may be external, such as the death of someone close to the individual or a sudden change in activity level. Or, it may be an internal stressor such as an illness. This paper outlines that in Kelly’s case, her stressors are: overload of work duties, work-life imbalance, her own personality traits and the personalities of the people she works with. The interplay of stressors and the consistent experience of high amounts in one’s life can often lead to burnout. The term â€Å"burnout† is a relatively new term, first coined in 1974 by Herbert Freudenberger, in his book, â€Å"Burnout: The High Cost of High Achievement†. He originally defined ‘burnout’ as, â€Å"the extinction of motivation or incentive, especially where ones devotion to a cause or relationship fails to produce the desired results.† While burnout is not a recognized clinical psychiatric or psychological disorder, there are some similar features between burnout and diagnosable conditions such as depression, anxiety disorders or mood disorders. Depleted Physical Energy: Prolonged stress can be physically draining, causing one to feel tired much of the time, or no longer have the energy she once did. Getting out of bed to face another day of the same gets more difficult.

Market Failure and Government Intervention Essay

Market Failure and Government Intervention - Essay Example Market failure is a situation that describes a situation where the effects of demand and supply do not allocate their resources appropriately. This will, therefore, lead to a situation that defines market failure as a marketplace where the unauthorized price system leads to an extremely high or low allocation of resources for specific economic activities. Market failure is always inherent to the market and consequently causes the market equilibrium allocation to be inadequate. In relation to the theorem of welfare economics, there is a possibility that under absolute conditions the allocation of resources in the long-run competitive equilibrium is efficient. Unfortunately, most of the markets always fail in the allocation of various economic and environmental resources thus making the overall allocation of resources inadequate. Adam Smith’s invisible hand is always a major principle in the allocation of resources. Various economists always refer these types of problems to approve the role for government intervention. A prominent economist once urged that existence of a free market always find it challenging to do away with the need for the government (Aldridge, 2005). In a situation where the positive externalities extremely exceed private benefits, the good produced or services provide become non-profitable in the market context, there will be always some benefits associated with goods or services that are allocated free. For example, one puts security lights in his or her compound to light the compound and neighbors use the light too to light their compounds free. The problem is that the market system cannot easily supply goods or services provided that are jointly consumed (Besanko, 2011). Consequently, for a market to work appropriately a two-party agreement is quite preferable. When non-paying parties cannot easily be excluded from the benefits of goods or services where the problem of the free rider arises. Good examples for such a situation include street lighting, roads, bridges, and drainage systems.

Is television a boon or a bane Essay Example | Topics and Well Written Essays - 500 words

Is television a boon or a bane - Essay Example The theme of the article revolves around the change our society, attitudes and priorities have undergone along with the percolation of television, internet and media in our lives. Joshua feels that our present space is becoming increasingly "virtual" than "real" like it was in the earlier days. We are no longer "with" ourselves, our loved ones and our surroundings rather, we are more focused and bothered about global issues, politics, entertainment , natural calamities in distant continents and so on . Although it is commendable to be aware of what is happening on our planet, it does not make our neighborhood problems or our loved ones' sorrows any less important. Joshua aptly sums up the scenario in a single statement- "the more we rely on our video window, the less relation there is between where we are and what we know and experience, the less there's a relationship between where we are and who we are". Television has broken down all barriers between men and women, adult and children, ethnic groups and nations. Today, if one does not have enough money to travel to exotic places, the option of clicking the remote and switching to a travel program is always there. Children of all ages are exposed to things that their earlier day's counterparts had not even heard of.

Assignment - Essay Example In addition, Lorcaserin is used by patients exhibiting at least one weight-related health problem such as hypertension and type-2 diabetes. In 2006, Phase III of the lorcaserin development program was started, and this involved three main trials: Behavioral Modification and Lorcaserin for Overweight and Obesity Management (BLOOM) trial, Behavioral Modification and Lorcaserin Second Study for Obesity Management (BLOSSOM) trial and the Behavioral Modification and Lorcaserin for Overweight and Obesity Management in Diabetes Mellitus (BLOOM-DM) trial (Bays, 2011). In general, all these trials showed that the participants showed weight reduction of between 5 and 10%. In all these trials, weight loss was observed after 52 weeks from the period of administering the drug. Overall, this drug has been found to be effective in reducing weigh in patients with and without the type-2 diabetes (Bays, 2011). In addition, the three trials also revealed that most of the patients involved in the study were satisfied with the performance of the drug. Since lorcaserin appears to be ell received by both patients and clinicians, it does offer an alternative to surgery. Despite the impressive results noted in the trials, a number of side-effects are associated with the use of lorcaserin. These include headache, nausea, dizziness, upper respiratory tract infections and nasopharyngitis (DiNicolantonio, et al 2014). In addition, there is concern that the use of lorcaserin is associated with increased incidences of depression. There is need for further analysis and understanding of the degree to which lorcaserin contributes to these side effects and how they can be minimized. Obesity is a big issue across the world. It is a major health concern because of the chronic illnesses associated with it. This brochure is therefore intended to enlighten adults, mainly between the ages of 18 and 65 years, on this new development in the treatment of

Risk Management Essay Example | Topics and Well Written Essays - 3000 words

Risk Management - Essay Example The three main management risks that the Company faces are (i) procurement risk; (ii) Human Resources Management risk; (iii) and, accounting risk. These three kinds of risks are common to large chain store like Wal-Mart (Zsidisin, 2008). Wal-Mart has employed improved management strategies to deal with the problems caused by these risks. As an international organization, Wal-Mart constantly faces the challenge of maintaining cohesion among its employees who are multiracial and multicultural employees. This has been a serious issue that Wal-Mart tries its best to grapple with since it began its globalization drive. Similarly, there are perpetual worries about risks inherent in the procurement and the computation of yearly financial accounting. These three operational risks are broadly described below. 2 Current Risk Management Process Since the nature of the risks is dynamic, Wal-Mart has always come up with the appropriate approach to identify, respond, monitor and mitigate or contro l the three forms of risks highlighted in the foregoing. Through efficient management procedure and principles, Wal-Mart has been able to keep its operational risks under control—some of the approaches utilized by the organization is described as follows: (i) Human Resource Management Risk:-Wal-Mart faces many risks arising from its sometimes inefficient human resources management. A few of human resources problems that have threatened Wal-Mart’s brand in recent years is the odd practice of treating women unequally with their male counterparts, subtle racial discrimination and also the policy of refusing jobs or promotion to employees that have on-the-job life-threatening injury (Spedding and Rose, 2007). This problem has caused the organization millions of dollars in legal damages over the years. As a result of this, Wal-Mart has implemented an effective approach to handle this brand-destroying risk. (ii) Procurement risk:- Wal-Mart also confronts incessant procuremen t risk like every other chain store that receive supplies from different kinds of suppliers. There are risks associated with the sources and quality of the supplies that are sold to customers. Are they from legal or counterfeit sources? Have the suppliers utilized illegal labor (like in China) to produce the goods? Are the 3 goods of highest quality consumable by people in other countries? Are there any standards that are laid down to encourage suppliers to think about consumers’ delight rather than insane profitability? (McCullough et al., 2008). (iii) Accounting Risk:- Chain stores always experience huge risk in computing all their financial transactions that would be presented in their yearly annual reports due to human errors, market forces and the improper utilization of accounting software. This problem has been recognized as a serious risk an organization must make efforts to mitigate (Chorafas, 2007). Other causes of financial risk include but not restricted to unstab le exchange rates (especially for a multinational), volatility in the financial markets, and accounting risks sparked by business risk (Chorafas, 2007). The flowchart below explains how Wal-Mart typically handles the three risks described above. Flowchart: Risk identification, response, monitoring, and control. (a) Identification: Risk managers or officers are distributed to each department to discover any claims of racial or gender inequality among Wal-Mart

Macroeconomics and Microeconomics - Interest Rate Assignment

Macroeconomics and Microeconomics - Interest Rate - Assignment Example A developed money market is essential to the development of an economy as it provides the sources of finance to carry out the necessary business transactions. Firstly, it provides the cash required on a short term basis to finance the working capital requirements of businesses and entire industries. Lenders can borrow the money from financial institutions to finance their necessary transactions and thus the money market allows the economy to keep running. It also helps to keep the financial institutions self sufficient as the institutions can recall their loans at any point if they need it. Money market instruments are significant for the central bank because it regulates and controls its monetary policy by increasing or decreasing the money market rates. It also provides the finances to the government who may issue treasury bills in order to finance its spending. (Importance of Money Markets) The money market rate is called the federal funds rate in the USA which is the lending of a vailable funds from one institution to another on a short term basis. Q2) The above figure shows the graph of the U.S. Federal Funds rate and the Treasury Bill rate over a period from 1991 to 2009. The interest rates of money market funds usually tend to move in the same way as the future interest rates are based on the expectations. The year 1991 began with the federal fund rate and treasury bill rate set at 5.69% and 5.41% and was on a constant decrease until the year 1993, after which it began to rise and more or less maintained the same level until the year 2000. In the year 2001, the terrorist attacks in U.S. badly damaged the confidence in the economy and the people, both local and foreign, were not willing to invest in the U.S., therefore the federal bank and the government reduced the interest rates in order to encourage the spending. The interest rate encouraged the potential investors to increase the borrowing and the investments along with decrease the savings. The govern ment, in 2004, increased the interest rates gradually and increased it constantly on a quarterly basis. After the interest rates reached a point of 4.5% to 5% in the year 2006, the world was hit by the recession and the central banks had to lower the interest rates to once again encourage the spending and investments in the U.S. economy to limit the recessionary impact on the economy. The government and the central bank still had to decrease the interest rates due to the recession and reached a low point of 0.16% in 2009. Q3) The above graph shows the money market rate and the treasury bill rate in Bahrain over the time period from 1991 to 2009. Again both the curves move in the same direction as they are based on the same expectations. The interest rates of Bahrain move in a direction similar to that of the U.S. because the currency of Bahrain Dinar is pegged to the U.S. Dollar. The Bahrain Monetary Agency (BMA) regulates the interest rates on a quarterly basis keeping the national and international indicators into consideration. The year 1991 began with a declining interest rate which was restored in 1993, similar to the case in the U.S. and the interest rates were more or less stable with only a few changes in it. This was the time when there was stability in the world throughout. However, in 2001 after the terrorist attacks, the economies throughout the world took a big hit especially the U.S. economy that had to lower the interest rates drastically until 2004. The same was followed by the Bahrain government

The year 1991 began with the federal fund rate and treasury bill rate set at 5.69% and 5.41% and was on a constant decrease until the year 1993, after which it began to rise and more or less maintained the same level until the year 2000. In the year 2001, the terrorist attacks in U.S. badly damaged the confidence in the economy and the people, both local and foreign, were not willing to invest in the U.S., therefore the federal bank and the government reduced the interest rates in order to encourage the spending. The interest rate encouraged the potential investors to increase the borrowing and the investments along with decrease the savings. The govern ment, in 2004, increased the interest rates gradually and increased it constantly on a quarterly basis. After the interest rates reached a point of 4.5% to 5% in the year 2006, the world was hit by the recession and the central banks had to lower the interest rates to once again encourage the spending and investments in the U.S. economy to limit the recessionary impact on the economy. The government and the central bank still had to decrease the interest rates due to the recession and reached a low point of 0.16% in 2009. Q3) The above graph shows the money market rate and the treasury bill rate in Bahrain over the time period from 1991 to 2009. Again both the curves move in the same direction as they are based on the same expectations. The interest rates of Bahrain move in a direction similar to that of the U.S. because the currency of Bahrain Dinar is pegged to the U.S. Dollar. The Bahrain Monetary Agency (BMA) regulates the interest rates on a quarterly basis keeping the national and international indicators into consideration. The year 1991 began with a declining interest rate which was restored in 1993, similar to the case in the U.S. and the interest rates were more or less stable with only a few changes in it. This was the time when there was stability in the world throughout. However, in 2001 after the terrorist attacks, the economies throughout the world took a big hit especially the U.S. economy that had to lower the interest rates drastically until 2004. The same was followed by the Bahrain government

The impact on Life Expectancy Essay Example for Free

The impact on Life Expectancy Essay AIDS has also caused the life expectancy rate to fall by 5 years since the start in 1900s. In Swaziland life expectancy has fallen to 33 which would have been 66 if there was no AIDS. Life expectancy also affects child mortality as there are many children who are born with the infection. Adults between the age group of 20 and 49 years are the worst affected. This group is about 60% of the sub-Saharan population which has increased from 20% between 1985 and 1900. This affects the prime working years of an adults life. This also removes the very people who could be responding to treatments and healthcare. The Economic Impact AIDS has affected the human development by impacting laborers, households and companies. It therefore damages the economy and the country finds it difficult to handle the epidemic. HIV and AIDS reduces the labour supply and increases mortality and illnesses. The government income also falls, tax revenues are cut and they are forced to spend more on dealing with the spread of the economy. The epidemic affects diversification of industries, exports and foreign investments which is very important for a country’s progress. Most of the countries struggle to meet their economic measures because they are still struggling with the epidemic as their GDP is affected which builds over a period of time. The ARV coverage of the drug needs to expand and reach more people than the economic growth rate will not reduce that fast. The Future impact of HIV/AIDS In future the aids epidemic will continue to expand because work in progress has not been able to sufficiently arrest the spread of the crisis. Domestic as well as international agencies are doing their best to extend healthcare and treatment to the millions affected with aids worldwide. Many people affected with AIDS are still not receiving the necessary treatments and campaigns have been unsuccessful in preventing new infections. The progress of the general development of infrastructure largely depends on problems such as poverty and poor public health. The main barrier to Africa’s progress and development is the impact of AIDS on all areas of functionality as discussed before. Africa can look forward to the future only if they can prevent and treat the HIV AIDS epidemic effectively and also care for the people affected by it. Science and Research According to UNAIDS Following are some of the steps in research that is being undertaken to prevent the spread of the HIV AIDS epidemic. The area of biomedical research makes use of humans to test drugs, vaccines and techniques that can be used to cure the epidemic. There are many ethical issues that is attached to it as complexities and advances in the research takes place. The 1964, Declaration of Helsinki sets out ethical guidelines and code of conduct for the research involved such as the use of animals for testing. The use of female condom, help prevent unwanted pregnancies, sexually transmitted diseases including the spread of HIV. These cheaper brands available have the capacity to be accepted and utilized worldwide. Male circumcision also helps in reducing the spread of sexually transmitted diseases from men to women if it is implemented in the safe way where there is consent. Research also involves the development of microbicide which is a gel or cream which can be applied to the vagina giving women greater control when men don’t want to use condoms. These microbicides will help prevent unwanted pregnancies as well will prevent the spread of the HIV. The other area of research is the use of vaccines. However there are many laboratories and companies involved in its development and are working towards making a breakthrough in the field. Conclusion The impact of the HIV AIDS epidemic is not only restricted to sub-Saharan and African countries but it is an international crisis. The international community along with research companies needs to get more involved in preventing the spread of the epidemic as well as the rehabilitation of the patients that are affected. We need to work more aggressively to arrest the disaster that is waiting to spread across the globe. Works Cited AVERT. ORG. Impact of HIV AIDS on Africa.

Looking At Wireless Power Transmission Information Technology Essay

Looking At Wireless Power Transmission Information Technology Essay Wireless power transmission is the process of transmitting electrical energy to an electrical load, from a source emitting power without interconnecting wires. The wireless transfer of electromagnetic energy as in different forms like audio format, video format and data format is common nowadays but wireless power transfer technology is still years ahead. Even though the idea was developed 100s of years ago and scientists are still working on the topic an efficient way for wireless transfer of power is yet to be developed. The development of highly efficient WPT technology will be a breakthrough in the history of wireless transmission as it allows lots of portable devices to be charged without plugging on to a socket or docked to a charging station. The development of WPT serves to be useful in many ways, as transmission of power in hazardous environment is inefficient and dangerous. The WPT differs from the wireless transmission of telecommunication signals as the WPT takes into consideration the efficiency parameter where as in the latter the energy parameter is significant only if the signal is distorted in such away that it cannot be distinguished. The WPT is economical if and only if the receiver receives the same amount of energy transmitted by the source. The direct induction method is the most common method used for the WPT and is being used for short distance WPT, but it had disadvantages and was overcome by later technologies developed like the resonant magnetic induction method, electromagnetic radiation methods like microwaves and lasers. The modern era where the ideology of high efficiency in practical circuits comes to existence, the WPT technology proves wrong due to the low efficiency of the developed technologies. The WPT technology in industries by electromagnetic radiation is possibly only remote in the design and most of the industries are looking forward for better designs for better efficiency in power transfer. Most of such design lags the property of safe human environment for living and the economical barriers. A design of WPT system which overcomes these factors is still to be worked out and is being experimented throughout the world. Why Wireless Power Transmission (WPT)? The studies throughout the world has proven that most of the electrical energy transfer is done through the interconnection wires and lots of energy is lost during the transmission due to various internal and external factors like the resistance of the wires the material of the conduction wires, the size of the wires, the atmospheric conditions like temperature, humidity etc. On an average basis the loss of power due to transmission through wires is calculated to exceed to be more than 30%. This is where the WPT comes into action , the WPT is highly reliable, fast , low cost for the maintenance and can also be used for short range and long range distance transmissions. These factors pop-in the idea for WPT. History of WPT The WPT history can be traced from the early 19th century. The first electromagnet was developed in the year 1825 by William Sturgeon which paved the way for the discovery of principles of magnetic induction in the year 1831. This was followed by the demonstration of transmission and reception of electrical energy without wires to connect the point of origin and termination by Nicholas Joseph Callan using the above two developments. These experiments even though demonstrated was successful but in practical cases was always kept under suspicion which was due to the interpretance that it was not possible for long distance transmission and fear of safety. The invention of transmission of very and ultra high frequency radio waves dedicated to Heinrich Hertz followed the revolutionary development of the wireless electricity transfer by Nikola Tesla in the year 1891, on which he took the patent-ship for illuminating the bulbs wirelessly. Nikola Tesla is called as the pioneer of the induction techniques as his technique was based on induction method. His vision of WORLD WIRELESS SYSTEM which inculcated the idea of people accessing the free energy. He even planned to set working a 187 feet tall tower for broadcasting energy but was put down due to lack of funds. The experimentation in early 20th century was successful in transmitting power over a distance wirelessly but was not able solve the problem of power loss due to hindrances. In the 19th century WPT passed through various phases of technological developments. Even after 100 years the idea of Tesla is being used by the MIT scientists led by Soljacic for their project named WiTricity. Different technologies of WPT Near-field techniques: The techniques for short distance transmission of power wirelessly. Mostly the induction methods are used for near-fields. These techniques are as follows. (1)Inductive coupling Electromagnetic induction is a process whereby a conductor placed in a changing magnetic field results in the production of voltage across a conducting plate. This voltage in-turn generates an electrical current called the induced current because the current on the second conductor is induced by the first. In the inductive coupling technique the primary and the secondary are not connected by wires but the energy is transferred by mutual induction. Mutual induction refers to the generation of EMF in circuit due to a change of current in nearby circuit. Electromagnetic increases with the increase in current, the voltage in the conducting plate responsible for the magnetic fields and also the increase in the frequency. The energy is transmitted from the conducting plates which is responsible for the fields to another conductor termed the secondary where the fields impinge on. A part of the energy on the primary is passed inductively through space decreasing the energy in the primary and imparting energy into the secondary. High frequency currents are not liable to pass the current for long distances but transfers energy by induction rapidly to the adjacent or neighboring conductors. Lower the frequency of the current less preponderant becomes the effects of induction. The phenomenon is classified more local, if the energy decreases rapidly in the circuit causing the current in the circuit to die-out. In the space outside the conductor the phenomena results in dielectric stress and steady magnetic condition for continuous current and alternating for alternating current input. For the telecommunication channels the magnetic and electric fields outside conductor is only considered for the transmitting and receiving of messages. Transformer working is the simplest example for WPT. A current which is varying in the primary generates a varying magnetic flux in the core of the transformer which results in the varying magnetic field in the secondary. This field induces a varying voltage or EMF(electromotive force) in the secondary. This is termed as mutual induction. It should be noted that most of the energy transferring devices are usually air-cored. There are many examples of air-cored devices, such as the wireless charging pads, electric brushes etc. Induction coupling is the underlying principle of charging of an electric toothbrush. The input current through the primary winding creates a magnetic flux thus a magnetic field. When the toothbrush is placed in the charger, a current is induced in the secondary by the magnetic field, which is connected to the batter of the brush and thus recharges the battery. The wireless charging of the portable devices of great advantage as it is comfortable to use, shock proof and less usage of wires which is more economical. The figure() shows the picture of an wirelessly charged toothbrush. The principle to recharge several devices at a time is similar to that of the charging of electric brush. The Splashpower recharging mat and Edisions Electric PowerDesk are few examples. The WCP (wireless charging pads) are devices that are devised for the charging the battery automatically when placed on it. There is no connection with the wires between the charging pad and the device battery to be charged. The technique of induction to transfer energy is utilized in this and air acts as core. Resonance Inductive Coupling It is the combination of resonance principles along with the inductive coupling principles. When a relatively low frequency close to the same frequency of vibration as the natural frequency of system being resonated produces large amplitude of vibration it is called resonance. Two objects or bodies are made to strongly interact with each other during the time of resonance. It is also noted that an objects physical structure determines the natural frequency of vibration of the object. Objects vibrate more easily at resonant frequency than at other frequencies. We know that magnetic flux developed due to the passage of current in the primary creates a magnetic field which induces an EMF in the secondary and thus current was the principle of inductive coupling. Working principles of Resonance Inductive Coupling. The coil in the fig() provides the inductance when the circuit is supplied with voltage. The induction takes place in a slight different manner when the electromagnetic fields surrounding the coils start to resonate in the similar frequencies. The inductor used here is a curved coil wire. We also see a capacitance plate attached to each end of the coil to hold the charge, that is a capacitance, is connected in parallel to the coil on both sides that is the primary and the secondary coil. When electricity is passed through the coil the coil begins to resonate. The resonating frequency is the product of the capacitance of the plates and the inductance of the coil. Electricity which travels alongside the electromagnetic wave tunnels from the source coil to the target coil, if both of the resonant frequencies are the same, where resonance is a function of the product of the capacitance connected in parallel and the inductance of the coil. Loss of energy or power due to radiation is negligible in this case. If the two coils to be linked are out of range of one another, there occurs no transmission of power as the fields are not strong enough to affect the surroundings. This is the same affect when two coils which are resonating at different frequencies exists. Considering two coils resonating at the same frequency to be in the same range, energy streams moves from the transmitting to the recipetant. This theory also provides the functionality of more than one receiving coil in the same range operating at the same resonant frequency to function. This type of energy is termed as NON-RADIATIVE ENERGY TRANSFER as it involves the static fields surrounding the coils more than the fields spreading in all directions. Advantages of Resonance Inductive Coupling (RIC) over Inductive Coupling Compared to inductive coupling the efficiency of RIC is very high. The range of RIC is much greater than compared to the inductive coupling, range for inductive coupling is below 5 cm whereas for the RIC it in the range of few meters. The directivity of the RIC is larger compared to the inductive coupling. RIC can implemented in one-to-many format, but the implementation of inductive coupling is generally one-on-one format. The devices implemented using RIC are easily portable compared to that of the inductive coupling gadgets. This is because of the small size of the component structure and the ease to use. Air Ionization Ionization of air refers to the process of imparting charges that is negative or positive charge to the air molecules by the application of high voltage. In this method of transferring the electricity, the charged particles that are the anions or cations move from the source to the target terminal through the atmosphere, by imparting charges to the air molecules. This technique even though seems to be simple in construction, it is the most toughest and un-economical method of transfer of power in the near field techniques. The disadvantages are really more in this technique because minimum field strength of 2.11 Megavolt is required to transfer the electricity over a distance of 1 meter, which is very high potential difference to be created. There should be a static atmospheric condition for this technique to be implemented and mostly the dust particles in the atmosphere can also affect the transfer of electric power, from one terminal to the other terminal. The natural example is the lightening which occurs. So taking into consideration all the negative points which overcome the advantages, it can be concluded that Air ionization method for wireless energy transfer is not feasible for implementation. Advantages of near-field techniques The absence of wires is being considered as the greatest advantage. There is no presence of e-waste. The need for battery is suppressed to a certain extent. Efficient energy transfer using the RIC up-to a distance of few meters is possible. The methods are harmless, if the strength of the fields used are under safety levels prescribed by the standards prescribed. The maintenance cost is considerably low for the devices in the near field techniques. Disadvantages of near-field techniques One of the main disadvantages of the near-field techniques is the distance. This technique implies the wireless transfer of energy only for a short distance. It has to be taken care of that, the strength of the fields developed should be below the safety level so that it does not affect the human safety. The initial capital for setting the circuit is considerably high. The tuning of the RIC circuit is a difficult task and consumes more time. The signals to the supply should be having high frequency because the induction is proportional to the frequency of the signal supply. The air ionization process for the near-field technique is not a feasible technique that can be implemented for the wireless transmission of energy. Far-field techniques for wireless power transmission Far-field techniques for WPT refer to transfer of power from one terminal to another terminal which is kept far apart. The techniques used for near-field transfer are not viable because the efficiency will be tending to zero or almost zero if implemented by those techniques. That is the power received at the receiving terminal will be zero. There are mainly two types of techniques used for the energy transfer in far-field techniques they are as follows Microwave wireless power transfer The electromagnetic waves that are arranged in between the infrared spectrum and the radio wave spectrum are termed as microwave. Their frequency ranges in from 300 Mega hertz to 300 Giga hertz. They are used for a wide range of applications such as Bluetooth, wifi, microwave Owen etc. The frequency range of microwave is in between 1 and 40 GHz which is generally used for applications. For long distance transfer of power, microwave is one of the best medium used. The microwave band is generally used because antennas of convenient sizes that are able to transmit and receive the microwave signals and also the metal waveguides for carrying the radio power works are available. Besides this the technologies in electronics where millimeter waveband is required the microwave proves to be helpful. This is because in millimeter wavelengths the radio waves are attenuated while the microwaves are not. The microwave was used for transmission of power for various applications such as running of the unmanned helicopter developed by Americans, powering the outer space vehicles etc. There are mainly three steps involved in the transmission and reception of power by MPT. Step1: The conversion of electrical energy into microwave. After this process the microwave is emitted with very-high power emitters called the cavity magnetrons. Step2: The microwave is then captured using a rectenna. The rectenna is a combinational circuit consisting of rectifier and an antenna. Step3: Microwave energy is converted to electrical by the rectenna. In the process of transmitting microwave, the AC supply needs to be converted to DC as it is not possible to convert the AC directly to microwave. The process of conversion of DC to microwave is done by magnetron. The magnetron is a highly powered vacuum tube structure that is responsible for the production of coherent microwaves. The rectenna can also be called as rectifying antennae as it converts the microwave directly into DC electricity. Rectenna consists of elements that are sorted in multi element array and consists of pattern reflector element mesh to give directionality. It is easily constructed by placing Schottky diode in between the antennae dipoles. The DC is converted back in the next process using an inverter circuit. Considering the receiver to be a photovoltaic cell, the microwave system for earthbound applications exceeding an area limit of diameter size 10 Km the arrays in the receiving station has large power levels in total , limiting the exposure of electromagne tic radiations which is considered for human safety. A density of power equals to or less than 1mW/cm2 is considered safe for human environment, and with this density of power for a diameter of 10 km 750 megawatts of power can be generated. This standard value is utilized by several modern power plants in the world. Laser transmission of power A device emitting electromagnetic radiation by the process of optical amplification on the basis of stimulated emission is termed as laser. Laser has high directivity and high degree of temporal and spatial coherence which is a unique property of laser that cannot be attained by any other technologies. The laser beams does not get dispersed for long during the time of transmission. The disadvantage of the laser is that it gets attenuated while propagating through the atmosphere because of hindrance due to the dust particles prevailing in the atmosphere. The receiver designed for the laser power transmitter and receiver is simple in design and construction. The laser system is a cost efficient system due to the simple design and structure. These points form positive side for the implementation of the laser system. The receiver in the case of laser system is a photovoltaic cell. The laser system is mainly used when electromagnetic radiation in the spectrum near to visible region that is 10s of nm or microns are to be transmitted, power is transmitted changing electricity in the form of laser beams and then projected onto a photo-voltaic cell which acts as the receiver. The receiver then turns it back to electricity. This is called the power beaming mechanism. This is so called because power is forced or beamed at the receiving end to convert the power into useful electric energy. The fig() shows the concept how laser is used for transferring the power to an object in the sky. Here it represents flying objects battery being charged by controlled transmission of laser beams, tracking the object with the help of the radar, and powering the target with the help of laser generating source. Comparison of Laser and Microwave techniques Laser method requires antennae of smaller sizes compared to that of the microwave technique of power transfer. Microwaves interferes with each other where as laser is highly monochromatic and does not interfere (two frequencies used for microwave power transfer are 2.45GHz and 5.4 GHz). Laser gets attenuated and also diffracted due to the particles present in the atmosphere, but microwave is resistant to this. Transmission of energy over a long range is possible due to property of collimated monochromatic propagation of wave-front in lasers but the range of microwave is small considered to lasers. The receiver size of the laser technique is small considered to the microwave method because of the compact size of the photovoltaic components. The laser beams does not affect or interfere the normal radio communication due to the large difference in their wavelengths, but microwave as it has wavelengths closer to that of the radio communication channel wavelength the possibility of interference is more. The photovoltaic cells in the laser receiver is not as efficient as in the microwave receiver as in laser, only 40%-50% efficiency is only acquired. Advantages of far-field energy transfer Far-field energy transfer is more efficient. The need for setting substations, grids etc are eliminated due to the large distance transfer ability. These systems require less maintenance cost compared to the wired system of energy transfer. The systems become more and more effective if the transmitter and the receiver are along the line of sight. This system can be implemented in remote locations where access is difficult. Disadvantages of far-field energy transfer techniques This is radiative in nature so the losses are prevalent due to the radiations. In order to be more effective in working the transmitting and receiving stations must be in line of sight. When lasers are used: (1) conversion to electrical energy is inefficient at the receiver. (2)absorption loss is high due to the atmospheric particles which causes attenuation and diffraction in lasers(3) difficult to use in human environment. When microwaves are used (1) interference of two power signals (2) standards should considered for the sake of healthy living environment. Applications Near-field energy transfer Electric automobile charging The automobiles running on electricity are more common nowadays as it more environmental friendly, but the storage capacity of these vehicles are limited as it cannot afford huge batteries, so similar to the petroleum bunks, rises the concept of recharging stations. But these recharging stations cannot afford large number of plug-ins, as the density of vehicles increases besides it is a waste of time working with plug-ins in this busy and fast world, so wireless recharging of the vehicles is done in these situations to avoid waste of time and energy by near-field techniques, besides all these many vehicles can be recharged at a time using resonance inductive coupling. Consumer electronics In the world of consumer electronics, the technology changes are really fast. Each technology brings in more compacability and introduces more functionality into the products being manufactured. Such a world essentially requires the introduction of the wireless charging, because it reduces the cost of the wires plugged on to it, increases the reliability of use of the equipment, reduces the total size of the equipment and increases the ease of portability etc. Inductive coupling or resonance Inductive coupling techniques prove to be useful in these cases. Example is electronic toothbrush charger, splash power recharging mat etc. Industrial applications In industries there are processes involving high temperature, hazardous environment created by chemical reactions etc. In such an environment if wires are used for the transfer of electricity if required, it is highly inefficient and at times dangerous, so in such cases only the wireless transfer of electricity is possible, the methods of inductive coupling and resonance inductive coupling proves to be efficient because the hazardous environment or the high temperature does not affect the transfer of energy wirelessly. Far-field energy transfer Solar power satellites In this era of growing need of energy, our mother earth with all its resources may not be able to supply enough energy for the utilization for mankind, besides the energy earned from coal, oil etc are causing pollution besides this, these non renewable sources of energy. So in order to satisfy human needs one of the latest technologies for energy harvesting is the solar power satellites. These are machineries working on the basis of the microwave and laser power transmission methods. These helps to efficiently make use of the solar energy, and are placed in geostationary orbits for the efficient working. Solar energy is captured using the solar cells on the satellite; where in 400 million photocells are present in each solar power satellite. The energy is converted to microwaves or laser and transmitted to the earth and received at the earth station using the rectenna or photovoltaic cell converts it into electrical energy. The efficiency of the microwave system is more than 95% usually, but for the laser power transfer system the efficiency is around 40% to 50%. The diagram in the fig() shows the working of the solar power satellite and how it transfers power from the supply terminal to the receiver terminal by microwave method of power transfer. This is also called BEAMING DOWN process. Energy to remote areas In remote location that is places that cannot be accessed easily by people, the transfer of energy by using grids are considered to be waste of money, time and energy. In such cases the transfer of energy through wireless media is only possible. Certain factories which produce hazardous wastes, confidential or secret services offices and plants of nations etc are sometimes located in remote locations are the examples. There are villages to be supplied with electricity located in remote locations government of nations are planning and implementing far-field techniques of power transfer to meet these tasks. Energy broadcasting globally The concept of energy broadcasting globally had bought in nations to work together in projects dealing with more efficiently trapping of solar energy to power up their resources. As solar energy is renewable source and available in plenty the only step left behind is more efficient way of trapping the solar energy. The achievement of this would certainly result in reducing the crisis of energy, and to broadcast the energy globally. One of the famous projects undertaken is based on Kalams (former Indian president) vision which calls in the program for space-farming to contribute substantially for the global energy broadcasting. One such proposal is Pan African e- network. Projects established on the basis of wireless power transfer. Wi-Tricity This was a project done in Massachusetts Institute of Technology on wireless transfer of energy based on the resonance inductive coupling method. The team was led by Marin Soljacic. The team was able to transfer energy wirelessly for a distance of 2m. The coils used for the experiment was helical in shape and they never used any capacitor in the experiment. The energy received at the receiving terminal was almost 40% of the total input power from the supply. The frequencies used for the transmission of power were 1MHz and 10MHz. The field strengths were safer at 1 MHz frequency for the human environment. The usage of 10MHz frequency, created fields of strength above the ICNIRP (International Commission on Non-Ionizing Radiation Protection) standards. Rectenna in US The rectenna build in USA worked on the microwave method of wireless energy transfer. The rectenna which was spread over one and half mile in was diameter was able to generate electric power of 5000MW. The range of frequency of microwave used is compactable to the ICNIRP standards. Alaska 21 WPT can be used for supplying power to rural areas. Alaska 21 project was presented in the year 1993, for supplying power to villages in Alaska. The other sources of energy were not possible to be used because of the limited infrastructure. The price estimate of $40/kWh was done for energy produced by other sources, which is too high to accommodate. Even cabling to this area was not possible due to extremes of climatic conditions. So a pilot project was conducted which was passed on WPT, not only to supply energy but also to avoid pollution. The system consisted of 2.45 GHz design array and could bridge around 1 to 15 miles. Present status is unknown. Grand Basin project This project aims in supplying electricity to an isolated mountain village in the remote area of the La Reunion Island. This project was developed for making Grand Basin to a tourist village. The project was given complete support by CNES, which is the French space centre. WPT was used as the underlying basis of the project. Planning to build a microwave link which operates at 2.45GHz frequency working over a distance of 700 meters delivers 10kW and had an efficiency of 57%. The whole system worked in combination with the photovoltaic panels and the batteries. Capital of 1 million dollars for 10 kW was proposed and the project was put down. WPT Demonstration in Hawaii In the year 2008 on moth of May a demonstration based on WPT was held on the islands of Hawaii. The demonstration was organized by one of the US based companies named Managed Energy Technologies. They were able to demonstrate wireless power transfer up to a distance of 148 km. They were only able to transfer 20 watts of power, which would barely light a fluorescent lamp, because most of the energy were lost during the time of transmission. The limitation of this demonstration was not the science but the capital involved. This project involved less than a million dollar. If the company could have afforded more number of solar panels and more phased transmitter array and receivers more than 60% of efficiency could have been acquired. Munich electronica exploration The Munich ELECTRONICA exhibition organized by the automotive, embedded, electronica and the ZEVI forums in the month of November from 9th to 12th in Germany was a real trade off for the electronics products. There were 2595 companies participating in the exchange and almost 70000 visitors took part in the exhibition. The exhibition is being conducted every two years alternatively to the Productronica. There were participation of various companies dealing with different types of electronic goods like the displays, connectors and interconnects, semiconductors, automotive, sensors, passive components, assemblies and sub-systems, wireless, embedded systems, power supplies, test and measurement etc. It is one of the best places where we come to know about different technologies, products and even test the new product to confirm our expectation. The fair also is business area where companies come for advertising and selling their products. I was able to visit stalls of 37 companies dealin g with power supply devices and gathered informations which I was able to present on the topic wireless transfer of power. Certain companies were doing research works on this topic but were not able to introduce their products because certain defects were yet to be cleared before manufacturing. Companies visited RRC Solutions The company was established in the year 1989, with the excellent management has become one of the leading companies in the supplier of power supplies and battery chargers. It has a good platform for the professional applications in medical, industrial, military and consumer products. The company has good wealth of expertise engineers creating new and innovative ideas. The company has its branches in various locations of the world with its headquarters in south west Germany. Its branches are located in USA, Japan, China, Hong Kong etc The companys products involve battery chargers, power supplies, integrated system solutions, products
