Challenges and most effective measures Essay

Population has been growing drastically for several years. It is shown that the world population has increased from 2 billions in 1930 to 6.8 billion in 2010 (Black, 2010). Feeding such a rapidly growing population has always had many challenges, however, with the population expectancy of 9 billions by 2050 only adds to the already very omnipresent pressure and concerns. In a world where already one billion people are currently suffering from chronic hunger , it is time to have a plan with solutions that will allow to feed a quickly expanding population growth. This essay will explore those the different measures that can be taken such as; using resources more efficiently shifting diets away from meat and reducing food waste while overcoming the endless challenges that are constantly faced. Three interlinked challenges are to be surmounted, the world’s food system must guarantee that all seven billion people alive today are adequately fed; it must double food production in the next 40 years; and it must achieve both goals while becoming truly environmentally sustainable. One of the measures to do so is by using resources much more efficiently leading to a much higher crop output per unit of water, fertilizer and energy. To do so there are three different actions that agriculture can adopt throughout the world. The first one is knows as drip irrigation which is the technique of applying water directly onto the plant instead of wasting water by usually spraying into the air. The second technique is mulching which is the action of coating the soil with organic matter in order for the moisture to be retained by the soil which will also reduce the water lost from irrigation systems as it will reduce the amount of evaporation let out from reservoirs and canals. Another dilemma comes from the use of fertilizers. While some lands lack many nutrients and therefore have poor crop production, other have too many nutrients which results in creating pollution. Many countries are believed to be able to reduce using fertilizers whit little or no impact on food production, examples are China, Northern India, Central U.S. and Western Europe. Another measure that can be taken to fulfill the feeding of the world’s population is shifting our diet to an all plant diet. Shifting away from meat product as simple at it seems would have a huge impact on the food  available for humans by using more of our crops to feed people directly and less to fatten livestock. ‘Globally, humans could net up to three quadrillion additional calories every year – a 50 percent increase from our current supply – by switching to all-plant diets.’ (Foley, 2011) Moreover, switching to an all-plant diet has more benefits as a balanced diet made of grains and different types of vegetables is considered healthier than a diet composed of red meats along diary products. This measure is seen as the hardest and is in need of better understanding. ‘Naturally our preferences are unlikely to change completely. Still, even small shifts in diet, say from grain-fed beef to poultry, pork or pasture-fed beef, can pay off.â €™ (Foley, 2011) The most important measure that should highly be taken is reducing food waste in production and distribution. Although it may come off as an obvious measure, it is rarely followed. ‘Roughly 30 to 40% of food in both the developed and developing worlds is lost to waste’ (Godfray et al, 2010) In the more developed countries, food waste tends to happen from the consumer’s side. Changing our consumption ways could have a significant effect on the losses we generate. Avoiding throwing food in the trash, avoiding overly big portions and avoiding restaurants and takeouts on a daily basis are all examples of how to reduce food waste. In poorer countries however, food waste happens from the producer’s side. An under-developed base and markets leading to food not being delivered, crops wrecked by pests are all ways by which food is wasted in under-developed countries. There are several ways in which food wastage could be prevented, although no food wastage at all is nonsensical, a smaller amount of it is still achievable. ‘Improved storage, refrigeration and distribution systems can cut waste appreciably.’ (Foley, 2011) As said by Godfray et al, (2011) there is no simple solution to sustainably feeding 9 billion people. However different measures can be taken to maximize the output while using the resources at a rate that does not exceed the capacity of the earth to replace them. Achieving a reduction in the consumption, allowing introduction to cold storage and public investment in transport infrastructure would all lead to a more efficient  food production system. The biggest challenge that will be confronted by society is coming up with ways to feed 9 billion people while being sustainable. It will require inventiveness, awareness, purposefulness and most importantly an extensive amount of labor. It will require people from all over the world to come together and work along one another. There is no time to lose. References Black, R 2010, Global population study launched by Royal Society. BBC News, viewed December 8th, 2013 Godfray, H. C. J., Benddington, J. R., Crute, I.

Minority Media in the U.S Essay Example | Topics and Well Written Essays - 1000 words

Minority Media in the U.S - Essay Example One of the most remarkable characteristics of the Hispanic media is the sheer size of its audience. There are approximately 40 million Hispanics in the US, the largest US minority, and 88% of them view Spanish language television (Porter 55). The number of Hispanic television viewers in Los Angeles is greater than the entire viewing audience in Boston (Ballve 20). In addition, nearly 80% of Hispanics listen to Spanish speaking radio and has resulted in Hispanic advertising growing at a rate of 20% in 2002 nearly 3 times the English speaking rate (Porter 55). These statistics translate into dollars as Hispanic radio and TV stations and their broadcasting networks bring in billions of dollars. Before the media industry was worth billions of dollars while selling politics and products to millions of listeners, there were newspapers and periodicals. Kanellos points out that there are two distinctive Hispanic media in the US; the immigrant media, and the primarily native Hispanic press, which is directed at the US citizens of Hispanic descent (4). By the mid-nineteenth century, both natives and immigrants were creating Spanish speaking newspapers and periodicals (Kanellos 3). These circulations would form the genesis of the Hispanic press and the coming electronic media. Kanellos contends that in 1910, during the massive immigration of economic and political refugees from Mexico into the US, the Hispanic press began to define itself. Publishers and columnists advocated using the press for the "defense of the community" (Kanellos 4). According to Kanellos, "...defense meant protecting immigrants civil and human rights, but just as important it also meant protecting the commun ity from the influence of Anglo-American culture and the Protestant religion" (4). It is on this foundation that the Hispanic media has been able to build a cohesive base that centers on a common

Performance Management in Education Essay Example | Topics and Well Written Essays - 3250 words

Performance Management in Education - Essay Example Average spending per pupil is approaching that of independent schools. Rather than the lack of resources, the reason for poor performance lies in the structure of the education system. In the absence of parental choice, British schools have been subjected to increasingly strong direction from central government. While the aim was to achieve a minimum level of achievement for all children, the result has been persistently low standards, inequity and burdensome regulation Research (Oct,2005) done by the independent think tank Reform shows that radical education reform, based on allowing parents to choose either state or independent schools at the taxpayers' expense, is supported by a half of all voters and would create thousands of new schools. A Reform study, The potential benefits of real education reform in England, includes detailed research into the system of school choice in Sweden, held up last week by the former Minister Alan Milburn as a model for the forthcoming White Paper on secondary education. Sweden has seen a dramatic increase in the number of taxpayer-funded independent schools in all areas of the country, including rural and deprived areas. If the Swedish experience was replicated in England, real reform would lead to over 3,500 new schools in twelve years. Reform also released an ICM poll on education reform. ... If the Swedish experience was replicated in England, real reform would lead to over 3,500 new schools in twelve years. Reform also released an ICM poll on education reform. It shows that 76 per cent of voters think that state education is in need of a fundamental review and 49 per cent support choice of both state and independent schools on the Swedish model. A majority of 18-34 year-olds support radical reform. The study shows that the Government's general election manifesto gives it the mandate it needs to introduce radical reform. But unless the key principle of reform is accepted - that taxpayers' money can follow parental choice freely into the independent sector, allowing new schools to open according to parental demand rather than Local Education Authority decision - any change will be slow and any improvement limited. The Reform report shows: 1. The Prime Minister and other senior Labour figures have said that a key objective for this Parliament is to increase the number and variety of state schools in England. They have argued for barriers to the opening of schools to be removed and for new schools to be run by private and voluntary providers. 2. This objective is right. At present the provision of schools and school places is not demand-led by parents but centrally planned by Local Education Authorities. The effect of planning decisions over the last two decades has been to reduce the number of schools and to limit the choices available for parents. Since 1984, the total number of state schools has fallen by 13 per cent (a fall of 3,267 schools) in a time of rising pupil numbers. Prime Minister and other senior Labour figures have made clear that a key aim of their policy for Parliament is to increase the number and variety of state schools

Employment Law - Problem Question Essay Example | Topics and Well Written Essays - 1000 words

Employment Law - Problem Question - Essay Example In the first count, Diana, a waitress who has just had a baby, is anxious about how she will manage her baby care and her work so as to plan her schedules. She approaches Christian who dismisses her that he is not involved in her issues and that she will have to cope with her current schedule at work. She has worked at the firm for three years. The second count involves Essie who has been working in the firm for the past two years. She has not been in good terms with Christian because of his continuous jock over Essie’s driving skills. She has never liked the jokes, has made this clear to Christian, and has asked him to stop. Christian however continues to make the joke. A statement that Essie ‘might kill someone one day due to her incompetence’ makes her angry and she leaves her job. In the third count, Fred, who has been working with Christian for 10 years, is approaching 65 years. He would like to work beyond the retirement age as he believes that he is still c ompetent but Fred believes that it is not safe to carry plates past 65 years and recommending that Fred leaves at 65 years. Rules One of the applicable rules in the case is the right of a woman to a flexible schedule after maternity leave. This is stipulated in the employment rights act of the year 1996 that allows the employee to apply for such varied conditions. For an employee to qualify for such rights as stipulated by the act, he or she must have worked for the employer for a period of two years and two months. There must also be the need for such change in schedule that must be primarily parental. A parent must for example be seeking the flexibility due to responsibility over a child who is younger than six years or an abnormal minor. Unless the employer can sight rational commercial arguments against such reschedules, the employee remains entitled to an agreed upon terms that remains binding (Chandler, 2003, p. 310). Another applicable principle in the case is the dismissal o f an employee. This, subject to the age discrimination principles of the employment rights act, can be observed from two perspectives; if the termination is done before retirement age and if the termination is done after the employee’s retirement age. Though the act provides that an employer have the right to dismiss an employee after the retirement age is attained, there should be an agreement between the parties over the termination agreement. This means that the employer should notify the employee of the intention to terminate the employment contact and the termination is only legal if effected after and not on or before the retirement date (Sargeant, 2006, p. 200, 201). Harassment is another applicable rule of law to the case. Harassments at the workplace include all forms of advances that are not welcomed by the recipient. Muir defines harassment from two perspectives, â€Å"quid pro quod claims and hostile environment claims† (Muir, 2003, p. 104). Quid pro quo re fers to those advancements that made with promise of rewards to the recipient, such as demand for sexual relations in exchange of promotion or an employment opportunity. Hostility in the working environment on the other hand refers to actions that are not acceptable to the recipient but are initiated by other parties at the workplace. Such an action may be â€Å"discriminatory that it affects job performance, or is intimidating, hostile, or offensive†

A Marketing Plan for the Budgens Research Proposal

A Marketing Plan for the Budgens - Research Proposal Example We will have to take special care to find out which of the environmental factors –social, political, cultural, economic, legal, technological-are the most important for the Budgens at the present time and which ones could be the most important in the next twelve to eighteen months. We should also concentrate on external agents such as competitors, suppliers, customers, trade unions, governments, shareholders, a local community which is affecting the company most.Here our client organization, the Budgens is planning for a period of 12 to 18 months in a market environment where the competition is severe from the big four supermarket retailers comprising of Tesco, Asda (Wal-Mart), Sainsbury’s, and Morrison’s. The sales forecast has to be done by taking to consideration of such competitor behavior and the market environment.The total environment can be segmented into three classes as 1.Mega environment 2.Micro environment. 3. Relevant environment. Out of these three groups as far as the now discussed market planning for the Budgens is concerned microenvironment is the most important one because the planning is for a relatively shorter period of 12 to 18 months. Therefore our important environmental factors of concern are suppliers, competitors, consumers, governments, local community, and shareholders.The main environmental advantages of the Budgens are their suppliers, who are quality assurance approved. Their independently functioning local retailers are in partnership with them. They care most for the quality of the food. They care for their consumers and the local community. As the Budgens is strictly abiding by rules, regulations and the government policies, there is no clash with the government. Now the only point of concern as far as the environmental factors are concerned is, from the competitors. Such issues we should address through the SWOT analysis and the resource analysis; and the findings may be taken seriously while proceeding t hrough the process of market segmentation, targeting, positioning Etc. Finally, the formation of the marketing mix and promotion policies are to be decided to base the above discussed environmental factors. The main factor needs to be focused on is the severe competition from the equally strong rivals. Advertising and other sales promotion policies such as offering discounts, special offers Etc. are recommended for the Budgens, based on the environmental analysis.   Thus a proper analysis of the environment, especially the analysis of the external environment will enable the company to locate its strengths and opportunities.

Organic vs. Inorganic Research Paper Example | Topics and Well Written Essays - 500 words

Organic vs. Inorganic - Research Paper Example If the evidence is not in its natural environment or has begun to decompose information about time and place can be found out from it. For example, the food inside of a persons stomach can reveal a great deal of evidence. It is organic matter. A simple grain of rice can be shown in a lab to have been eaten six hours earlier at a Mexican restaurant on the east side of town. That kind of information can be especially valuable to a forensic crime scene investigator. Plant matter on the sole of a shoe can be very useful to. The chemical composition of organic matter can point an investigator in useful directions. Perhaps the grass has been treated by pesticides. That will eliminate many locations, for example. Clearly organic evidence can be very useful. However, it has one main drawback when compared to inorganic evidence: it decays. Organic evidence will on be around for so long. Even if it is still at the crime scene when you arrive it muse be preserved carefully in the laboratory. If a fridge, for example, is accidentally turned off in a lab, the evidence will be lost. All living things decompose. The trick is to arrive at the scene quickly and secure all of the organic evidence as quickly as possible. If not, there is a good chance that it will be lost. This is especially important to consider when we look at how long a justicial proceeding can carry on for. These things sometimes take years. As such, from the moment it is collected, the organic evidence must be preserved. An expert report about it must be generated for the prosecution and it must be entered as an exhibit. At all times it must be carefully preserved. Unlike a glove, it will deteriorate over time. Inorganic evidence is heartier. It can lost for a long time, if not forever. This is evidence such as glass, rocks, or synthetic fibres. This kind of evidence can also be very revealing and tell a lot about a crime

The Foreign Corrupt Practices Act Research Paper

The Foreign Corrupt Practices Act - Research Paper Example INTRODUCTION This paper shall discuss the Foreign Corrupt Practices Act of 1977 (FCPA), which is a United States federal law passed mainly to ensure accounting transparency as mandated by the Securities Exchange Act of 1934. It also includes provisions meant to address the bribery of foreign officials. This paper shall discuss the act, including its pertinent details and essential provisions, as well as its reasons for passage and application. II. BODY The Foreign Corrupt Practices Act is a law which includes specific provisions on accounting and prohibitions on bribery (Cook and Connor, p. 2). The accounting provisions of the law are meant to prohibit illegal accounting practices which are often carried out to conceal corrupt practices. The provisions are also meant to guarantee that company shareholders, including the Securities and Exchange Commission are given an accurate picture of corporate status and finances (Cook and Connor, 2010). This law covers two groups of corporate per sonalities, first are â€Å"those with formal ties to the United States and those who take action in furtherance of a violation while in the United States† (Cook and Connor, 2010, P. 2). The US issuers and domestic concerns are required to heed the provisions of the FCPA, regardless of their actions being within or outside the US territories. Issuers are companies with securities in the US or those which are legally called for to regularly report with the US SEC (Cook and Connor, 2010). On the other hand, those under domestic concerns have a wider coverage, and include individuals or residents of the US. Corporations, partnerships, business trusts, sole proprietorships, and like entities are also covered under domestic concerns, for as long as their main place of business is in the US or their governing provisions are under the US laws (Cook and Connor, 2010). This act holds corporations and other entities legally liable for bribing foreign officials even if such act was carr ied out beyond American shores and throughout the years, various violators have been prosecuted under these provisions. The basic provisions of this law hold the following practices as illegal: â€Å"1) a payment, offer, authorization, or promise to pay money or anything of value; 2) to a foreign government official (including a party official of manager of a state owned concern), or to any other person knowing that the payment of promise will be passed on to a foreign official; 3) with a corrupt motive; 4) for the purpose of (a) influencing any act or decision of that person, (b) inducing such person to do or omit any action in violation of his lawful duty, (c) securing an improper advantage, or (d) inducing such person to use his influence to affect an official act or decision; 5) in order to assist in obtaining or retaining business for or with, or directing any business to, any person† (FCPA, in Cook and Connor, 2010, p. 2). Individuals and corporate entities violating th e provisions of this law can be held criminally liable and may be imprisoned and/or fined for their actions (Biegelman and Biegelman, 2010). The law also provides a generalized definition for what is to be qualified as ‘payment’ punishable under the FCPA. The FCPA defines these payments to cover any benefits (monetary or otherwise) given or gifted to a foreign official in order to curry favorable treatment in business activities with the involved foreign official (Cook and Connor,

South Korean Financial Crisis Case Study Example | Topics and Well Written Essays - 1500 words

South Korean Financial Crisis - Case Study Example Korea was progressing well in 1996 and had become a part of the Organisation for Economic Cooperation and Development (OECD). As people celebrated, nobody knew of the impending disaster about to strike. During the latter part of 1996, the current account deficit increased to 5% from previous year’s 2%, a decrease attributed to lessened competition among Korean industries. The GNP declined from 14.1% to become 7.1% and foreign debt rose to a high 100 billion dollars. These and various other debt related indicators were showcasing the upcoming crisis for Korea. The first half of 1997 surfaced a few more indicators of the disaster. Foreign investors in Korea were starting to get wary of the market and lacked confidence in investing because of long recessions, large deficits in current accounts and growing short-term external debt. In January 1997, Hanabo Steel, the 17th largest Korean seller went into bankruptcy. Soon the Sammi Group, another steel company, failed and major affil iates of the Jinro Group went bankrupt. In July 1997, another major automobile manufacturer, Kia motors failed. With the downfall, foreign capital began to flow out of the country. In July 1997, the Southeast Asian crisis broke out first in Thailand, followed by Indonesia, Malaysia and in Hong Kong in October as the stock market crashed. Within October to December, the Korean economy crashed by 112% compared to the US Dollar. ... Within October to December the Korean economy crashed by 112% compared to the US Dollar. From October 1997, the yield spreads of the global bonds of Korean Development Bank (KDB)3, Korea's indicators of the sovereign risk premium, started to jump. By early December, Korea's bonds were reassessed by Moody's and Standard & Poor's and were demoted to junk bonds from their A1 status. Soon the banks could not renew the maturing loans and needed to withdraw from the Korean markets. Foreign lending crashed from the $100 from January to October 1997, to minus $20 billion by the end of the year. The won plunged lower to 50% in a span of two weeks in the month of November. As of November 1997, foreign reserves were seen to stand at 24.2 billion dollars, of which only 9.3 billion dollars was finally available. The figure was much lower than the required foreign reserve level of 36 billion dollars. Korea did not have enough money to repay back its 10 billion dollars short-term borrowings. At the edge of sovereign default, foreign debt touched highs of 119.7 billion dollars and the whirlpool of the crisis was pulling in Korea. The Causes and effects of the Crisis The causes that led up to the crisis were many and experts state that a single cause cannot be pinpointed as the culprit. While the economy crashed along with that of other nations, many experts also state that the currency crisis in Korea is quite different from other traditional situations. This crisis had little to do with the mismanagement of monetary and fiscal policy. The macroeconomic fundamentals were also good. The effects were as diverse too, but boiled down to the financial destruction of Korea. However like every failure or

Product Life Cycle Concept Essay Example for Free

Product Life Cycle Concept Essay Michael Porter’s framework of competitive analysis is applicable to our business organization known as D.T.DOBIE TANZANIA LTD which falls under the automobile industry in Tanzania and worldwide in the following ways: A.Barriers to entry/threat of new entrants. Its true that the average person cant come along and start selling brand new cars. The emergence of foreign competitors with the capital, required technologies and management skills began to undermine the market share of brand new car sellers. The following factors are barriers to automobile seller’s new entrants: * Knowledge and Technology Ideas and knowledge of servicing its supplied products is the one that provides competitive advantage to D.T Dobie over others. D.T Dobie uses machines of highest technology on checking and servicing its cars in which, gives them power to provide guarantee of up to one year service to its product since they are assured of what they are doing. The machines used by the skilled labor of D.T Dobie to service and check the product are of high quality and they are very expensive in such a way that for new entrants firm in that business its an ownership barrier. * Access to distribution The demand for brand new cars in Tanzania is very low since they are sold at price that individual can’t afford. D.T Dobie is a greater supplier of brand new cars to Tanzania government institution, most United Nations (UN) organizations such as UNICEF, ILO, UNESCO, representative’s offices in Tanzania and embassies offices. Since these agencies are the most buyers of brand new cars, it has made D.T Dobie to have almost the access to distribution channel of selling brand new cars in which this act as barrier to new entrants since the buyers are few. * Cost of entry Initial capital required to set up a new firm is very high, it makes the chances of new entrants to be very less. * Product differentiation and cost advantage The product has to be different and attractive to be accepted by the customers. D.T Dobie is the greater seller of brand new NISSAN, MITSUBISHI, MERCEDES BENZ, HONDA and HYUNDAI in which made them different from its competitor since it sells many brands than others. By being supplier of government cars has made them to be exempted when importing cars for government institution uses. B. Bargaining power of suppliers: The bargaining power of suppliers is also described as the market of inputs. Suppliers of raw materials, components, labor, and services (such as expertise) to the firm can be a source of power over the firm, when there are few substitutes. Suppliers may refuse to work with the firm and also may charge excessively high prices for unique resources. For organization of our choice i.e. D.T Dobie its suppliers for motor vehicles are TOYOTA, NISSAN, MITSUBISHI and MERCEDES BENZ. D.T Dobie is the seller of brand new car in Tanzania where by its inputs i.e. imported new cars from great multinational companies are so important for its survival, this leads the suppliers having great power over D.T Dobie since it’s not manufacturer but the buyer of finished product. Increase in production cost to one of suppliers on specified product may lead to switching cost which will be relative to D.T Dobie switching cost. Degree of differentiation of inputs: D.T Dobie supplier’s supply different brands in which is difficult for them to switch from one supplier to another. For example if they are required by its customers i.e. government to supply cars that’s engine capacity is V8 that pushes them to deal with TOYOTA since other suppliers are not producing cars with that engine capacity. For parts suppliers, the life span of an automobile is very important. The longer a car stays operational, the greater the need for replacement parts. On the other hand, new parts are lasting longer, which is great for consumers, but is not such good news for parts makers. C. Bargaining power of customers: Buyers refer to the customers who finally consume the product or the firms who distribute the industry’s product to the final consumers. Bargaining power of buyers refer to the potential of buyers to bargain down the prices charged by the firms in the industry or to increase the firms cost in the industry by demanding better quality and service of product. Since our organization of our choice D.T Dobie supplies and sell brand new cars in Tanzania, its customers are few since who can afford to buy brand new cars are government institution, most united nations (UN) organizations such as UNICEF, ILO, UNESCO, representatives offices in Tanzania, embassies offices and individuals who can afford to do so. Since its customers only want quality and guaranteed products this act as driving force to D.T Dobie to supply not only quality products but also quality parts and servicing those cars for the whole year as guarantee after being sold out. Since D.T Dobie is greater supplier of brand new NISSAN, MITSUBISHI, MERCEDES BENZ etc. cars in Tanzania availability of substitute products such as FORD, RANGE ROVER, LAND ROVER which are supplied by its competitors like CMC motors and sold at same or at lower price than D.T Dobie’s have made some of its customers to shift to those brands as it’s known customers are very sensitive to price. Most of those mentioned above customers purchase in large quantities. They have full information about the product and the market. They emphasize upon quality products. They pose credible threat of backward integration. In this way, they are regarded as a threat. D. Threat of Substitute Products: Substitute products are goods or services from outside a given industry that perform similar or the same functions as a product that the industry produces. Rather than looking at the threat of someone buying a different car, there is also a need to also look at the likelihood of people taking the bus, train or airplane to their destination. When determining the availability of substitute’s time, money invested, personal preferences and convenience in the auto travel industry should be considered. D.T.Dobie should consider the following factors when analyzing this force: * Price Band The threat that consumer will switch to a substitute product if there has been an increase in price of the product or there has been a decrease in price of the substitute product. If the price of the cars sold by D.T.Dobie will increase the main expected customers i.e. the one switching from bike to car will not move to car and will remain in the bike only. Thus the price is kept checked in this manner. * Substitutes performance The performance of the substitute sector also plays an important role in the success of the business. If the price of other dealers such as Africariers increases or the price band of the small segment falls, it will have effect on the quantity required in the market. It’s just on the price but also the features and the other services associated or it may be the status symbol story. * Buyers willingness Products with improving price/performance tradeoffs relative to present industry products. It will determine the willingness of the buyer to buy from D.T.Dobie.The willingness of the customers to go forward to try the new product in the market such as Mercedes Benz reduces the threat from substitute products. E. Competitive Rivalry: This force analyses the level of competition between existing players in the industry. Because an industry’s firms are mutually dependent, actions taken by one company usually invite competitive responses. Thus in many industries firms actively compete against one another. Highly Competitive industries generally earn low returns because the cost of competition is high. The auto industry is considered to be an oligopoly (a market condition in which sellers are so few that actions of any one of them will materially affect price) which helps to minimize the price-based competition. Below are factors which are seen in this force: * Price Competition Advertising battles may increase total industry demand, but may be costly to smaller competitors. Products with similar function limit the prices firms can charge. Price competition often leaves the entire industry worse off.. * Product Quality Increasing consumer warranties or service is very common these days. To maintain low cost, companies consistently has to make manufacturing improvements to keep the business competitive. This requires additional capital expenditure which tends to eat up companys earning. On the other hand if no one else can provide products/ services the way you do you have a monopoly. D.T.Dobie enjoys the monopoly of selling new cars are there are no competitors in this segment. * Unique Selling Point Also D.T. Dobie has advantage over its rivals because it represents a premium brand which is recognized over the world, they found a niche in the market where have a leading brand like Mercedes-Benzes a and a brand which people aspire to own .Also they are lucky to have Nissan one of the most renowned Japanese brands which is an equal pillar of their business. * Expansion DT Dobie is looking to grow and move forward, both in its native Tanzania and in surroundings regions. By building strong relationships and working closely with strategic partners, DT Dobie’s footprint keeps on growing. Also they are expanding by appointing more dealers around the country. * Investment In terms of investing in our own equipment, this takes priority; they put all eyes on technology so they are not behind the rest of the world. Even if the latest technical advancement s are available to the company, DT Dobie makes sure any investment is benefiting to the organization as a whole .Every five years D.T. Dobie has an equipment review which makes sure the company is on right track, ensures investments have been successful and assesses whether upgrades need to be made in order to reach the next level, they are absolutely up to date. Also ensures that its vehicle testing equipment has modern standards which outnumber it from its rivals. CONCLUSION: In general, any CEO or a strategic business manager is trying to steer his or her business in a direction where the business will develop an edge over rival firms. Michael Porters model of Five Forces can be used to better understand the industry context in which the firm operates. Porters Five Forces model is a strategy tool that is used to analyze attractiveness of an industry structure. Porters Five Forces model views the business from inside and outside. It focuses on assessing competitive position within the industry.

Effect of Temperature on Vitamin C in Orange Juice

Effect of Temperature on Vitamin C in Orange Juice Abstract: This experiment was planned to study how different temperatures can affect the loss of vitamin C in orange juice stored for a fixed period of time. Equal volume of freshly squeezed orange juices with known (initial) vitamin C concentration were stored at different temperatures i.e. 10 °C, 20 °C, 30 °C, 40 °C, 50 °C and 60 °C for a constant duration of 5 days. After the storage period, the vitamin C concentration for each temperature was measured by DCPIP titration and the difference relative to the initial concentration was calculated to calculate the amount of vitamin C reduced. The result of this experiment showed that the amount of vitamin C lost increases with the increase in temperature and 10oC was the best temperature that gave the least reduction in vitamin C concentration. An analysis using Pearson product-moment correlation coefficient has revealed a strong positive linear relationship between the two variables with the calculated r value exceeds the critical va lue at 5 % significant level thus, supporting the experimental hypothesis. Vitamin C is a remarkable compound derived from one of the ascorbic enantiomers, L-ascorbate. It is a water soluble vitamin that cannot be naturally synthesized in human body.1 Therefore, it is vital to have our diet balanced with adequate amount of it every day. There are two important roles played by vitamin C; antioxidant and collagen formation.2 These two features have placed vitamin C in a class of its own as a future potential in fostering better health. A previous research regarding relationship between vitamin C and human brain has shown that vitamin C could help drugs to pass the blood brain barrier.6 This would enable brain diseases such as Parkinson to be effectively treated as artificial dopamine can be delivered directly to the brain. At the same time, the biggest challenge in bone marrow treatment i.e. getting enough cells, could possibly be solved as a recent study by Dunagqing Pei13 on vitamin C, has found that it can boost the production and pluripotency of stem cells in human body. However, Vitamin C is also known to be very vulnerable towards heat. The precursor of vitamin C, ascorbic acid, has molecular of C6H8O6. The proximity of highly electronegative oxygen atoms on the hydroxyl (OH) groups makes the hydrogen atoms to become easily detached from the structure. Meanwhile, the presence of heat causes the hydroxyl bond to break the ascorbic acid is said to undergo destruction or oxidation by losing hydrogen atoms, forming dehydroascorbic acid. Therefore, it is suggested that the rate of ascorbic acid destruction is significantly greater at higher temperature.* Most of the studies on vitamin C degradation are principally based on the effect of storage condition and period, and very few were done on identifying the degradation trend within a specific range of temperature. Previous research, on the effect of storage methods and conditions on vitamin C retention in human milk revealed that freezing reduces the least amount of vitamin C as compared to other storage methods, followed by refrigeration which is better than cold water. Another study at Ankara University, has shown an inverse relationship between temperature and retention rate of vitamin C in citrus fruit concentrates, while orange fruit was found to have higher retention ability than the others. Therefore, this experiment was aimed to find a specific trend regarding the effect of temperature on the loss of vitamin C. Citrus fruits (orange) were used in this experiment due to appreciable amount of vitamin C that they have, thus, increasing the reliability of the results. The results from this study can be used to illustrate how certain temperatures can cause drastic change in vitamin C hence, increasing the awareness on appreciating the effort of preserving vitamin C content in food for optimum health benefit. For instance, in agricultural tropical regions that grow citrus fruits, it becomes very vital to preserve the fruits at low temperature if possible due to higher chance of vitamin C destruction than other regions. Experimental Hypothesis: The higher the temperature, the higher the degradation of vitamin C in freshly squeezed orange juice. Null Hypothesis: There is no significant relationship between the different temperature and the degradation of vitamin C in freshly squeezed orange juice. PLANNING Five types of citrus fruits were randomly chosen, namel: lemon, lime, grapefruit, Clementine and orange. The fresh juice of each fruit was obtained through cutting and squeezing. The vitamin C content for each juice was determined by titration against 1 ml of 1 % DCPIP. The titration was repeated two times to get an average volume of the juice needed to decolourise DCPIP. The result: The least volume of orange was needed to decolourise DCPIP, indicating that it has the highest vitamin C content. Therefore, orange fruit was chosen as it would give significant response towards different temperatures. Determining the best storage period: Several orange fruits were squeezed to obtain fresh orange juice that would be enough for its vitamin C content to be measured on daily basis. Firstly, the initial vitamin C content of the juice was measured and 4.8 ml was needed to decolourise 1 ml of DCPIP solution. Equal volume of the remaining juice was divided into two beakers and each was stored in an incubator of different temperatures (10 °C and 60 °C). Two distinctive temperatures were chosen to allow easy comparison of the trend in each temperature. The result: The result shows no more change in volume of juice required after 5 days for 60 °C. Therefore, storage period of five days were chosen for the main experiment. MAIN EXPERIMENT Variables: Manipulated variable: Different temperatures (oC) (6 incubators were set at different temperatures of 10 °C, 20 °C 0, 30 °C, 40 °C, 50 °C and 60 °C) Responding variable: Amount of vitamin C lost (By DCPIP titration, the difference between initial and final vitamin C concentration in each juice was  calculated to determine the concentration of vitamin C reduced) Fixed variables : Storage period, volume and concentration of DCPIP, type of fruits (The storage period was five days. 1ml of 0.1% DCPIP  Used for each titration) Apparatus: Beakers, knife, test tubes, syringes, Parafilm, aluminium paper, incubators, mortar and pestle, measuring cylinder. Materials: Orange fruits, 1% dichlorophenolinophenol (DCPIP) solution, distilled water, 500 mg vitamin C tablet. Real Experimental Procedures: Standardizing Vitamin C Concentration: 1) A tablet of 500 mg vitamin C tablet was crushed into fine powders using a mortar and a pestle. 2) The powdery form of vitamin C was then dissolved into 100 ml of distilled water in a beaker to form 5 mg/ml of ascorbic solution. 3) 1 ml of 1% DCPIP solution was measured and placed into a test tube by using a syringe. 4) 1 ml of 5 mg/ml of ascorbic acid solution was then taken using a syringe and added drop by drop into the measured DCPIP solution until decolourised. 5) The volume of ascorbic acid solution needed to decolourise the DCPIP solution was recorded. 6) The titration process was repeater three times to get an average volume. The result of titration is as follows: Volume of Juice Titrated / ml Hence, 2.5 ml of 5 mg/ml of ascorbic acid solution was needed to decolourise 1 ml of 1% DCPIP solution To find a formula to calculate vitamin C concentration in orange juice, Conc. of orange juice (mg/ml) Vol. of orange juice (mg/ml) = 5 mg/ml 2.5 ml Since the volume needed to decolourise is proportional to vitamin C concentration. So. Conc. of orange juice (ml) 2.5 ml = 5 mg/ml Vol. of orange juice (mg/ml) 2.5 ml Concentration of orange juice (mg/ml) = X 5 mg/ml Vol. of orange juice (ml) Therefore, this calculation would be used to calculate the vitamin C concentration. Determining vitamin C loss: 10 orange fruits were cut and squeezed to obtain fresh juice. 1 ml of 1% DCPIP solution was measured and placed into a test tube by using a syringe. 1 ml syringe was filled with the orange juice and added drop by drop into the DCPIP solution until it decolourised. The volume of juice added was recorded. The titration was repeated five times to get an average volume and its vitamin C concentration was calculated using the derived formula. The juice was then divided into 6 equal volumes and each placed into 100 ml beaker. The top of each beaker was sealed with Parafilm and its surface was wrapped with aluminium paper and labelled with different temperatures. The beakers were placed in six incubators of different temperatures according to the label and left for five days. After five days, the beakers were sealed off. 1 ml of 1% DCPIP solution was measured and transferred into a test tube by using a syringe. The orange juice stored in 10 °C was taken by a syringe and added drop by drop into the DCPIP until it decolourised. The volume of juice added was recorded The titration was titrated three times to get an average volume and its vitamin C concentration was calculated using the formula: 2.5 ml Concentration of orange juice (mg/ml) = X 5 mg/ml Vol. of orange juice (ml) Steps 8-10 were repeated but this time using the orange juices stored in  °C, 30 °C, 40 °C, 50 °C and 60 °C. The difference between the initial concentration and the final concentration of each juice was calculated to determine the amount of vitamin C lost. Risk Assessment: The process of cutting the orange fruits required the use of knife, so it was done carefully to avoid any injury. The fruits were then squeezed very gently to minimise heat production. The juice was only prepared right before the experiment was about to be carried out. DCPIP is a strong dye which is hard to be removed so lab coat was worn. During the titration of juice against DCPIP, the test tube was not shaken vigorously to avoid oxygen from dissolving. The juice was discarded immediately after the experiment. Results: Statistical Analysis: Based on the result from the table, it is known that there is an obvious trend and correlation between the temperature and vitamin C loss. Therefore, Pearson product-moment correlation coefficient (PMCC) was chosen to measure the strength of this relationship. In this method, the value of correlation coefficient, r needs to be calculated which ranges from -1 to 1. The details of its values are as follow: Therefore, the value of correlation coefficient, r, using Pearson product-moment correlation coefficient has shown a strong positive linear relationship between temperatures and loss of vitamin C. Hence, null hypothesis is rejected. Data Analysis: Table 4 shows the volume of the freshly-squeezed orange juice needed to decolourise 1ml of 1% DCPIP solution. The average volume was used to calculate the concentration of vitamin C present initially. Meanwhile, Table 5 shows the amount of vitamin C concentration reduced after being stored at different temperatures for five days. From the table, there is an inverse relationship between the vitamin C concentration left and the amount of vitamin C lost. There is also a huge difference in the amount of vitamin C left between the juice stored in 10 oC andt the one stored at 60 oC, which is 2.11 mg/ml. This represents 77.6% of the original concentration of vitamin C. The calculated statistical correlation coefficient, r of 0.9584 is absolutely a strong indicator to support this relationship. Graph 1 illustrates the trends and correlation between the two variables. From the graph, it can be concluded that generally, the higher the temperature, the higher the amount of vitamin C lost. 10 oC is the best temperature that gave the least reduction in vitamin C level with only 0.12 mg/ml (4.4%) decrease after five days. Meanwhile, 60 oC caused maximum drop in concentration after five days with 2.23 mg/ml (82%) of vitamin C had lost. The largest gap in vitamin C loss occurred between 40 oC and 50 oC with 1 mg/ml (37%) of increase recorded. Based on the graph, the amount of degradation at 20 °C and 30 °C opposed the general trends when 0.6 mg/ml vitamin C had lost at 10 °C which is greater than 0.56 mg/ml at 30 °C. However, the difference is so small which suggests that this anomaly might be due to several reasons: Higher rate of oxidation of ascorbic acid by oxygen in the atmosphere. False end-point titration Apart from that, the results obtained have also shown that there is only a little change in vitamin C concentration from 10 °C to 30 °C. However, drastic change in concentration started to occur after 40 °C. This suggests that orange fruits should be kept below 30 °C with better vitamin C retention at lower temperature. Evaluation: From the results of the experiment, the huge difference in vitamin C lost between 40 °C and 50 °C could be explained by the presence of enzyme ascorbate oxidase in citrus fruits. The function of this enzyme is still not fully understood, but one best suggestion is that it might involve in controlling the oxidation process of ascorbic acid.12 Just like any other enzymes, when the optimum temperature is exceeded, the bonds holding the ascorbate oxidase together start to break and it is said to be denatured. Therefore, the destruction of ascorbic acid takes place without any control. Measurement of vitamin C in this experiment was done by titrating the juice against dichlorophenolindophenol (DCPIP). It is a strong oxidizing agent with distinctive blue colour and decolourised when being reduced by vitamin C.15 Therefore, the destruction of vitamin C by heat means that more is needed to decolourise DCPIP solution. Oxidation of DCPIP by oxygen in the atmosphere is one of the limitations of this experiment. Hence, the test tubes were not shaken vigorously during titration in order to minimise this limitation as vigorous moves can increase the rate of oxygen dissolving in a solution. The other limitation could be the side decomposition of vitamin C due to the presence of light and air. Just like temperature, ultraviolet ray from incidence light causes the hydroxyl bond in ascorbic acid to break, thus become oxidised. To reduce this limitation, the beakers containing orange juice to be stored at different temperatures were neatly wrapped with aluminium paper which is a good reflector of light and heat. The surfaced of the beakers were also sealed with Parafilm. This would prevent the entry of air and significantly reduce unnecessary oxidation of vitamin C in the juice. Several modifications can be made in the future to improve the accuracy and reliability of the results of this experiment. Iodine titration could be used as an alternative for DCPIP titration. Although this technique may require the use of more reagents, the result from the trial experiment has shown that the end point of titration is much easier to be identified. Besides, orange juice could be obtained by blending the peeled orange fruits instead of squeezing them. This ensures maximum amount of juice obtained from each fruit as well as preventing destruction of vitamin C by heat. Finally, percentage of vitamin C degraded can be used as the response variable instead of concentration. This would allow clearer illustration of the amount of vitamin C reduced for the readers and also make the comparison process easier. Conclusion: Based on the result of this experiment, it can be concluded that the higher the temperature, the greater the degradation of vitamin C in freshly squeezed orange juice. The statistically calculated r value using Pearson product-moment correlation coefficient, 0.9584, is significantly higher than the critical value at 5% significance level thus, providing a strong evidence to support the hypothesis.

Complications of Endoscopic Sinus Surgery

Complications of Endoscopic Sinus Surgery INTRODUCTION: Endoscopic sinus surgery, a widely used method in the treatment of chronic sinus disease can lead to major (0-1,5 %) and minor (1,1-20,8% ) complications. These complications are still important nowadays. Central nervous system (CNS) fistula, hemorrhage, meningitis, orbital injury and even death are major pathologies. These are usually the result of injury of fovea ethmoidalis or orbital structures [1-4]. If the skull base anatomy and its possible variations are well known these risks will be minimized. ‘Fovea ethmoidalis’ which seperates ethmoid cells from anterior cranial fossa forms the roof of ethmoidal labrynth [5, 6]. Fovea ethmoidalis adheres to lateral lamella of cribriform plate which is a medially located very thin bone [7]. Keros [8] classified the depth of olfactory fossa as the height of lateral lamella in 1962. According to his classification if the height of lateral lamella MATERIAL-METHOD Two hundred paranasal sinus computed tomographies performed for various reasons as a total of 400 hemisides of paranasal region were analyzed retrospectively. Patients under 18 years of age, with a history of prior surgery, trauma which led to massive destruction of bones and patients with congenital anomalies were excluded from the study. A hundred of the patients were female (18-77 years old, mean age: 36,91) and 100 male (18-76 years old, mean age:34,25), respectively. MDCT scanner (Siemens Medical Solutions, Enlargen, Germany) with consecutive 1mm thick sections were obtained and coronal multiplanar reconstructions were performed. Bone algorithm was used. In our study , we measured that the depths of olfactory fossa, identifying Keros types, the distances of the ethmoidal roof from hard palate, the distances between upper and lower limits of the orbita bilateraly. The height of ethmoid roof was calculated by measuring the distance between ethmoid roof and the upper limit of orbit a. Measurements in coronal sections were performed at the level of the optic nerve just posterior to the orbital globe. Also the shapes of the bone from the confluence of ethmoidal fovea with lateral lamella are called type 1 if its shape looks like a broken arrow (broken wing) and type 2 if its shape is flat (flattening) and forms of the asymmetry were investigated. Keros typing, ethmoid roof height and asymmetric shape of the fovea were investigated in both sexes whether there is a relationship between them. NCSS statistical analysis (Number Cruncher Statistical System) 2007 Statistical Software (Utah, USA) was performed with the package program. Data were evaluated by descriptive statistical methods (mean, standard deviation), as well as comparisons between groups one-way analysis of variance, in the sub-group comparisons Tukeys multiple comparison test, in the binary comparisons of groups and independent t test, in the qualitative comparisons of data chi-square and weighted kapp a compatibility test was used. Results significances were evaluated at p RESULTS: According to the classification of Keros, 3.75% of the patients Keros type I (n = 15), 59.5% Keros type II (n = 238), 36.75% Keros type III (n = 147). Keros type III is more common in males (n=86, 43%) than females (n=61, 30.5%) (p = 0.017). The shapes of fovea ethmoidalis in 97.25% (n = 389) of the patients were the broken arrows (type 1), while 2.75% (n = 11) of the shapes were flat (type 2) . In 54 cases (13.5%) an olfactory fossa Keros type asymmetry, in 11 cases (2.75%) foveal shape asymmetry was found. In seven patients (3.5%) as well as the foveal shape asymmetry also Keros olfactory fossa type asymmetry was seen . Keros type I patients’ orbital maximal height average were measured 33.07  ± 1.24 mm, Keros type II patients 32.57  ± 1.97 mm, Keros Type III patients 33.31  ± 2.11 mm respectively. In the male patients , the average heights of the orbits of Keros III group were significantly higher than Keros group II (p = 0.034). The olfactory fossa depth was measured at an average 6.45  ± 2.16 mm on the right , 6.39  ± 2.21 mm on the left. The average depth of the olfactory fossa in males (6.7  ± 2.45 mm) was higher than in females (6.13  ± 1.84 mm) (p = 0.01). There was no significant difference between the olfactory fossa depth between type 1 or type 2 foveal shape. Right and left olfactory fossa depth which were used for detection of Keros typing was compared. In 93 patients (46.5%) from the total of 200 patients asymmetry was detected. In 55 patients > 1 mm (27.5%), in 38 patients had > 2 mm (19%) difference was found. Forty-eight of them female and 45 were male. In seven of the same patients showed foveal shape asymmetry also. Average right ethmoid roof height 7.59  ± 2.25 mm ,average left ethmoid roof height was measured 7.75  ± 2.38 mm. In men with type 2 foveal shape the groups average height of the ethmoid roof (9.59  ± 2.77 mm) was higher than the foveal shape of type 1 group (7.66  ± 2.36 mm) (p = 0.042). In women, the average height of the ethmoid roof of type 2 group (8.75  ± 1.76 mm) was higher than type 1 group (7.34  ± 2.11 mm) (p = 0.03). There was no statistically significant difference was observed between the averages of heights of ethmoid roofs in Keros type I, II and III patients. Right and left ethmoid roof heigh ts were compared in total of 200 patients. There was an asymetry between left and right sides in 93 patients (46.5%) . In 55 patients > 1 mm difference (27.5%), in 38 patients had > 2 mm difference (19%) was found. Forty-nine of them were female, 44 of them were male. Five of the same patients showed asymmetry in the shape of the fovea also. In 54 patients (27%), asymmetry was observed in both ethmoid roof height and olfactory fossa depth . Twenty-nine of them were female, twenty-five of them were male. In the same group; the foveal shape in four patients showed asymmetry also. For the Keros type I patients both sides of the olfactory fossa depth asymmetry ratio was found to be more (53,3%) than the other types. For the same measurement, the ratios were found 40,8% and 29,4 % with Keros type II and type III respectively. Kerosian ethmoid roof height of both sides in patients with type I, asymmetry ratio was found to be greater (40.0%). For the same measurement, the results were 33.3% and 29.4% in Keros type III and type II respectively. In the Keros type I patients foveal shape asymmetry was found to be greater (20.0%) than the other types . The foveal shape asymetry for Keros type II was 4.2% and 4.08% for Keros type III respectively. DISCUSSION: The ethmoid sinuses have special importance especially in patients undergoing sinus surgery . Because these sinuses are close to vital organs such as the anterior cranial fossa, dura, orbita, optic nerve and anterior ethmoid artery [12, 13]. During endoscopic sinus surgery, the maximum likelihood of injury of the skull base is in Keros type III cases in which olfactory fossa are deep [9]. In 1962, in Keros’ study with 450 patients, type II patients at a rate of 70.16% (which was the most common type in that study), type III 18.25% and type I 11.59% of the patients [8]. In our study 3.75% of the patients were Keros type I (Figure 1), 59.5% of the patients were Keros type II (Figure 2), 36.75% of the patients were Keros type III (Figure 3) . After the point of the junction of fovea ethmoidalis with cribriform plate as well as the depth; the shape and symmetry of these structures are also important . In our study, in 93 patients (46.5%), olfactory fossa height asymmetry was detected and in another 93 patients (46.5%) foveal shape asymmetry was found. In 54 cases with height asymmetry there was also shape asymmetry (27%). In a study made by Basak et al. [14] in Turkey on 64 children with Keros type I, type II and type III incidences were explained in the following way; 9%, 53% and 38% . Anderhub et al. [15] researched 272 cases of German children for the analysis of cases of ethmoid roof . The results of their study were as follows: 14.2% of the patients Keros type 1, 70.6% of the patients Keros type II, 15.2% of the patients Keros type III . In Jang and his collegues study [16], on 205 adult patients, type II was the most common (69,5%). In Alazzaw and his collegues study [17] on 150 patients with 3 separate ethnic group type I 80%, type II 20% and type III 0% of the patients were detected. In a study made by Elwany and et al. [18] on 300 Egyptian 42,5% of type I, 56,8% type II and 1,4% type III were found respectively. In this study, the type II olfactory fossa was the commonest type in men (66.7%), while the type I fossa was commonest in women (53%). In a study made by Souza et al. [19] on 200 Brazilian with type I 26,3%, type II 73,3% and type III, 0,5% of reported cases. Solares et al. [20] in United States examined 50 cases, 83% of the cases type I, 15% type II and %2 type III respectively. In a study in Turkey Erdem et al. [21] showed 8,1% in 136 patients with type 1, 59,6% type II, 32,3% type III; Sahin et al. [22] in 100 cases detected 10% of the patients type I, 61% type II, 29% type III. Dr. Satish Nair [23], found that 77,2% of type II in the study, 17,2% of type I and 5,6%. of type III 5,6% respectively. As seen in the studies, differences are observed between different countries. In a study by Lebowitz et al. [24] 200 paranasal tomographies were interpreted. In 86 of the cases, olfactory fossa shapes were symmetric and their heights were the same. Ninety-six cases had shape asymmetry, 19 cases had height asymmetry in olfactory fossa, one case had both shape and height asymmetry. In a study made by Dessi et al. [11] on 150 Italian patients, 10% identified asymmetry of the height of the olfactory fossa. In Fan and et al. [25] studies’ on 160 Chinese patients, 15,6% of cases showed olfactory fossa height asymmetry, 38,75% of cases had foveal shape asymmetry. Souza et al. [19] showed ethmoid roof height asymmetry in 12% of the cases, contour asymmetry in 48,5% of the cases. Michael Reiss et al. [26] studied 644 patients, of which 31 % was detected height asymmetry. Kizilkaya et al. [2] reported that in 37,95% patients was detected height asymmetry. Dr. Satish Nair [23] identified height asymmetry in 11,7% of the cases. In the same study, ethmoid roof heigh t and contour asymmetry was found in patients at the highest rate with type I (67,8%); than 32,3% and 40% with type II and type III followed. In a study made by Kaplanoglu et al. [27] on 500 patients ; in 80% of cases was found height asymmetry, the foveal shape asymmetry was detected in 35% of the patients in the same study. Our current study in patients with Keros type I both olfactory fossa depth and height of the ethmoid roof asymmetries had greater percentage. But in our population Keros type I is less seen. However, most of the skull base injuries were seen in Keros type III cases at a prevalance of 36,75% in our study in which olfactory fossa depth and height of the ethmoid roof asymmetry rates were quite high (respectively 40,8%, 33,3%). Preoperative computed tomography must be interpreted in detail. Especially Keros typing must be done and all the variations should be evaluated carefully. CONCLUSION In patients undergoing endoscopic sinus surgery; knowledge of anatomic details and average lengths of skull base and their neighbouring structures and the possible variations of anatomical structures are very important for the prevention of complications that may occur during the operation. Therefore, the preoperative evaluation of paranasal sinus CT by considering the various possibilities is necessary and inevitable. REFERENCES 1. Hemmerdinger SA, Jacobs JB, Lebowitz RA.

Clozapine :: Drugs Science Medical Psychology Essays

Clozapine Clozapine is an atypical anti-psychotic medication that acts as an antagonist (a drug that blocks the effects of a neurotransmitter), thus producing an inhibitory effect, at a variety of neurotransmitter receptors in the brain. The exact site and action by which Clozapine produces its therapeutic effects is difficult to locate due to the complexity of its interactions with several neurotransmitters. It is believed that the two key neurotransmitters that Clozapine interacts with are serotonin (5-HT) and dopamine (DA), particularly at 5-HT2, D2, and D4 receptors (Brenner, H.D., BÃâ€"ker, W., Genner, R., 2001). Serotonin is a biogenic amine derived from tryptophan that generally produces inhibitory postsynaptic potentials (meaning that it causes hyperpolarization of the postsynaptic cell membrane).Functions of serotonin include regulation of sleep and emotions. Dopamine is a monoamine catecholamine derived from the amino acid tyrosine. Receptors that bind dopamine are termed dopaminergic. Dopamine is one of the principal modulatory neurotransmitters in the brain and may have inhibitory or excitatory effects depending upon the response of the postsynaptic receptor (King, www.indstate.edu). Clozapine also has effects at muscarinic M1 receptors, adrenergic receptors, cholinergic receptors, and histamine receptors (Brenner, et al). There are many disputed theories of the biological causes of schizophrenia. One of the most prominent ideas is the "dopamine hypothesis." The dopamine hypothesis attributes hyperdopaminergic function, meaning an excess of dopamine at certain synapses, as a possible cause of schizophrenia (Fann, W.E., Karacan, I., Pokorney, A.D., & Williams, R.L., 1978). Dopamine systems arise from two primary midbrain clusters, the ventral tegmental area and the substantia nigra which have discrete projections to mesolimbic, mesocortical, and striatal regions of the brain. The neurochemical anatomy of dopamine differs in cortical and striatal regions, and it appears that dopamine concentration, receptor regulation, and D2 receptor density varies greatly between striatal and extrastriatal regions (Jones, & Pilowsky, 2002). It is supposed that the therapeutic actions of antipsychotic drugs are exerted via the mesolimbic and mesocortical dopamine pathways in the brain (Hyman et. al., 1995). According to the dopamine hypothesis for schizophrenia, limbic D2 receptor blockade is essential for a drug to have antipsychotic activity. It is believed that the therapeutic actions of antipsychotic drugs are exerted via the mesolimbic and mesocortical dopamine pathways in the brain by acting as D2 receptor antagonists (Hyman et al.)Without exception, effective antipsychotic drugs have at least some degree of antagonism of the dopamine D2 receptors.

The Battle Of Blu-Ray versus HD-DVD Formats Essay examples -- Technolo

The Battle of Formats There are two new formats of DVD's coming out one is Blu-ray and one is HD-DVD, will this become the battle of VHS vs. BetaMax and which will be in your home. First, let me give you some history on both of these new forms of DVD's. Blue-ray which was invented by a group of companies called Blue-ray Disc Association. It consists of companies like Sony, Apple, Dell, HP, and many more. Blue-ray will hold 25 gigabytes and will be the same size and shape of a DVD. The only difference is that it uses a different laser which is the color blue. Now you know why they called it this. The big factor that will push Blue-ray to be in your home is that Paramount Pictures, Universal Studios, and Warner Bros will be big supporters of Blue-ray. Another big feature is that it will feature DRM which is digital rights management. Blue-ray has another form of encryption called BD+ that will allow the companies to change the encryption. This will make it very hard to make copies of their products like movies and software. HD-DVD was introduced on the DVD forum and on November 19, 2003 they decided that the HD-DVD format be the new DVD to output HD movies. HD DVD was originally called Advanced Optical Disc. Like Blue-ray it is the same size as Cd's and DVD's. HD-DVD's will only hold 15 gigabytes, 10 less than Blue-ray. HD-DVD uses a red laser to burn information and read information. This product is supported by Toshiba, NEC, Sanyo, Microsoft, HP, and Intel. Now the type of copy right protection that HD-DVD is some what like Blue-ray. They will have a Watermark Protection. All HD DVD readers will check for this watermark and if does not see the watermark it will refuse to play the disc. Manufacturers have also discusse... ...3i, spath &.

The Way We Were :: American America History

The Way We Were As you listen to the news, radio, or read a newspaper, you notice one thing in common after the 9/11 attacks on the World Trade Center in New York City--unity. New Yorkers have known to be "hard-ass'" and the rudest people you'll ever meet. Self-indulged in their own world, they knocked people down who stood between them and the next step ahead of them. We, as Americans, felt the effect of the destruction all over the nation, although it didn't happen in our hometown. Most people either knew someone, or knew someone who knew of someone that worked in the WTC building or were on those flights. Not until our safety was raped from us did we stop to unite, as a country, to help those in need. America is known as "the land of opportunities." Therefore, we are taught that to obtain our cultural goals, we must try to achieve them by almost any means necessary. America was a very self-absorbed country. For instance, look at the 80's, that era named "the era of greed." We're a very wealthy country; with wealth comes greed. We like to keep money in our pockets at all times--meaning we always want to have money. Everywhere you look now, there it is, the American flag: our symbol of pride. "One nation, under God with liberty and justice for all." We have become united as a nation. The American Red Cross has raised millions of dollars with the help of normal, everyday citizens. Celebrities have joined together and held telethons to raise millions of dollars also. The American flag has been in such high demands all over the country that they're almost impossible to find in stores. From car washes to simple donation buckets in supermarkets, everywhere you go people are contributing. Before the 9/11 attacks, one would never have doubts about who's on the same flight as you, or feeling compelled to wash your hands after touching the mail. We took for granted what most people don't have--freedom. The freedom to walk down the street without the fear of seeing a terrorist act and living without the fears of being on a national heighted security alert for more terrorist attacks. Hell, we're "the land of the free," or perhaps we took for granted that we really were. Because of these attacks, many people are having second thought about doing many everyday things.

How can ICT Help Special Needs Children Integrate Themselves in Society?

How can ICT Help Special Needs Children Integrate Themselves in Society? â€Å"We are seen as ‘abnormal' because we are different, we are problem people, lacking the equipment for social integration.† (Brisenden, 1986) Not so long ago, society was to blame for secluding and cutting off special needs people, from complete partaking in society and as a result, these impaired people ended up demoralized and feeling inferior to others. Today we know that special needs people, try their best to learn to communicate with the rest of society. The problem is not whether they succeed or not, the problem is; Are we, as part of society, doing enough effort to help them in their lifetime struggle? The International Society for Technology Education (ISTE) has recently initiated learning environments which integrates Computer Technology and Good teaching in order to increase the motivation and self-esteem of special needs students. Researchers following closely the program have stated that Computer technology enhances these children's ability to solve problems and make decisions, they build a positive self-image, they are excited about learning and thus they become better citizens. One major reason for using ICT was to reduce the large rate of dropouts. Researchers have concluded that Children with Literacy Problems (mostly dyslexics), often lack behind the rest of their class, give up on learning and end-up as school dropouts, feeling unable to fit in a society. ISTE has created a learning program called Video Disk Spaced System. This proved to be highly successful as it was not only a support for these children, in order to keep up with the rest of the class but it also managed to promote that positive self-image concept. Computer technology motivated these kids and they in turn appreciated the potential of ICT in a learning environment. Results have shown that ICT did help these special needs children as the dropout rate decreased to three times lower than the natural average. ICT can also help physically impaired children by fulfilling their dreams. In example Sharita a physically disabled child dreams to become a writer but unfortunately she cannot move her fingers. Computer technology has helped her fulfil her dream by devising a long extended stick in the form or a finger with which she can press the letters on a computer keyboard. Another concrete example regarded Megan who is unable to speak and write because she has Cerebral Palsy, however through ICT she was awarded as the Top English Student in her class. A Light Talker was devised, which is basically a matrix of letters and phrases. Through the use of a head switch (because Megan can only control the movement of her head), she can stop vertical movements of light at the desired row and stop the horizontal movement of light at the desired letter or phrase. Through ICT Megan is thus able to communicate with tremendous effort. However one has to keep in mind that without this device Megan can neither develop her intellectual potential, nor can she express herself as a part of society. Through the examples discussed above one can realise that by Integrating Computer Technology with learning, these special needs children are becoming more eager to learn, they are being provided with new ways to manipulate their environment in order to communicate better with the rest of society, barriers are being blown away and a variety of new worlds opened up, all by the use of Computer Technology. Apart from all this, ICT has provided them with what any individual wants that is their independence. Illegal Copying of Intellectual Property Alert!! You may be Unaware of Committing Computer Crimes†¦ * What is Illegal Copying? A widely used term which means the same as illegal copying is Copyright Theft or Copyright Infringement. Copyright theft occurs when making use of protected work such as: software programs; another writer's text; movies; sounds; and images, without actually paying the required fee for authorisation. * Illegal Copying and the Use of Computers: The use of Computers has made the act of copying far easier and handier than in the past. Burton (1996) argued that the Internet is one big copying machine that is basically ridiculing copyright laws. * What is considered as Copyright Violation? Software Piracy – Software copying such as copying a program from one diskette to another. Network Piracy – Distributing unauthorised copyright materials in digitized form ex: record companies have protested against sending unauthorized copies of digital recordings over the internet. Plagiarism – Illegal Copying of Academic Property: such as another writer's text, journals etc. Interpreting and presenting them as one's own. Ownership of media – Altering images, movies and sounds. * Plagiarism: Illegal Copying of Academic Property: You as a student may think it is harmless making one copy of an Academic Software program while the teacher is looking away, but you need to keep in mind that if all students should think the same as you think, then one single act of software piracy, will be then multiplied thousands of times. In addition to this if you are caught copying illegally Scholar property, you may end up sued by the school itself. Interpreting other writers' texts (found while researching for assignments) and presenting them as your own is also considered as a criminal offence and one can end up permanently suspended from school. * The Results of Getting Caught : If you are caught using pirated academic software, you could: Face civil fines (which you don't afford and your parents may want to kill you) Endure humiliating publicity End up with a criminal record (which affects you future) * A Word of Advice: It is not ethical to illegally copy any intellectual property nor is it worth risk taking because there is a high percentage of getting a computer virus and worse the risk of getting caught!

Genetic Diversity

Mutations are miscellaneous forms of changes in ones DNAs structure or fundamental law. This mental defectiveness can happen for various reasons much(prenominal) as chemical misuse, noxious viruses or environment factors. When a variance occurs in ones contagious structure, at that place is very much a push to find go forth what went wrong and if it was a onetime detail or a contractable abnormality that no one in the family k revolutionary just about until the recent discovery. This genetic abnormality occurs when there is a dominant gene which comes from a parent.This dominant gene attaches it ego to a recessive on the wholeele gene and sparks a change in the genetic sequence of the effect. This is most germane(predicate) as I was observing my nephew populate weekend. My brother is dark skinned, big and slim. My sister-in law is of French decent and abundant bodied while looking at my nephew, I ascertained that he is header towards his mothers side of the family he has the fair skin, finer grain of bull, and the full moon body of his mother, thus his natural appearance is a mixture of some(prenominal) his mothers and incurs genes along with a mutation of their DNA.Sexual imitation ensures life impart lapse no matter what happens. As genes are interchange between two potential parents, the resulting offspring ends up with a combination of genes from some(prenominal) parents which then in turn gives them their induce genetic makeup. This can lead to an enlargement in various parts of the human where there is a diverse genetic makeup of people. This is due to various factors such as economics, upward mobility and educational opportunities.When this occurs new communities develop, form and branch out spawning a growth in population and migration. As the various traits from ones genetic makeup mixes with others of another makeup, this boosters to further prolong the worlds eccentric makeup among its various populations and cultu res. As these factors come into turning over and over again, this helps to ensure the disaster of cloning ones self or someone else go away never happen.This also ensures the population will continue to grow change and the diversity of it all helps to make the world we live in today all the more unique and complicated. As I reflect on my nephews own unique genetic makeup, I cant help but wonder what his future will hold in regards to his own children, where he will migrate to and what he will contribute to leave his mark on the world. One can only bank that the traits and genes he has inherited from his mother and father will help him to reach his full potential.

Summary “The Environmental Issue from Hell”

Summary “The Environmental Issue from Hell”

We’re Hot as Hell Is global warming a moral dilemma? Is it the american public policy problem from hell? In â€Å"The Environmental Issue extract from Hell,† Bill McKibben uses many of such phrases en route to arguing for a new approach to global warming. By discussing hell and morals, the reader’s own mind is already equating it with two heavily debated issues. Therefore, we begin to question their existence and how we should  deal  with the subjects. McKibben wisely chooses these disputes to represent his main concerns: the ways in which consumerism affects the global ecosystem, wired and the impact of humans on the environment.Theres an overview of the insights of the chapter.(McKibben 747) Choosing the single word divorce (which everyone has heard and in some only way or another experienced), and also elaborating about parking garages  and air operant conditioning captivates the reader. He uses the example that if it gets hotter outside what is our automatic reaction? We turn the AC up without contemplation. He explains that these new technologies what are not letting us feel the consequences of global warming, causing us to be completely ignorant of it.Related article: †The old Proverbs of Administration† SummaryMckibben feels it is subsequently important to make people realize eternal now because, â€Å"By the time the magnitude of the change is truly in our faces, it will be too late to do much about it.Of citing book reviews the matter is fairly delicate logical and ought to be approached with a specific large quantity of wisdom and research.

Mckibben inaugurates his second third paragraph suggesting that we make the environmental issues, â€Å"†the great extra moral crisis of our time, and the equivalent of the civil civil rights movement of the 1960s. â€Å"(747). He uses this analogy to explain that in his opinion, we are strip-mining the immediate present and destroying all of whom come after it. Thus, leading him to discuss exactly how humans’ materialistic ways have impacted the earth.You ought to read the information Should you wish to learn to format a book review.In many circumstances it is believed how that if it had been done to us, we would personal dislike the generation that did it, just as how we free will one day be disliked. The solution given in the essay on how to handle these environmental issues is to start a moral campaign.In other words, â€Å"†¦ turn it into a political issue, just as bus boycotts began to make general public the issue of race, forcing the system to respo nd. â€Å" (748).Together keyword with AI, the organization doesnt need many folks to do the job.

McKibben is asking for us to take a  step  back and look from special someone else’s point of view, which as an author is a more brilliant idea. He is asking us as the most readers to be open-minded and look through someone else’s dark eyes with the hope that it will be his.
