Reasons for United States Possible Attack on Iran Essay Example for Free

Reasons for United States Possible Attack on Iran Essay The topic on the possibility of United States launching a military attack against Iran has dominated much news for several years since the Bush administration and during which some quarters speculated that such an attack would be ordered before the administration left office. As early as 2005, a number of articles had started revealing the imminent plans by Pentagon to order military operations against Iran. While people and the media may speculate and give their opinions about many aspects of the imminent war, the most important issue to understand is the reasons which may spark the attack. It is therefore the objective of this paper to discuss the reasons why US would engage in a military land war with Iran. 2. 0 The Euro-Based Oil Bourse This is one of the major reasons which revolve around the plan by Tehran government in 2005 and 2006 to start competing with the New York Mercantile Exchange (NYMEX), the largest physical commodity futures exchange in the world based in New York and the London based International Petroleum Exchange (IPE) by using the euro-dominated oil trading mechanism (Clark, 2004). The logic behind this is that by using this mechanism in international oil trades, the euro is going to take dominance and establish a firm ground which will serve to overshadow the strength of the U. S dollar in the global oil market. The U. S government therefore considers this a real threat by Tehran government which warrants intervention to protect the dollar from being toppled off from its long term monopoly in the critical international oil market. It is worth noting that lack of an oil pricing standard that is euro-dominated also referred to oil â€Å"marker† in the oil trading industry is one of the technical challenges facing the euro-based trading system in oil transactions. The oil markers currently in operation today are the U. S dollar dominated which include Norway Brent crude, West Texas Intermediate crude, and the UAE Dubai crude. In the spring of 2003, Iran laid down a requirement that all the transactions for its Asian and European oil exports be conducted using the euro currency though the pricing of oil was still predominantly controlled by the dollar. Following an official announcement in 2004 that Iran had intentions to develop an Iranian oil Bourse, it raised the concerns that a stiff competition would ensue between the Iranian oil bourse and the U. S owned NYME and the IPE (Clark, 2004). The macroeconomic implications of such a development would cause a shift in the international commerce in both Middle East and the European Union which is the largest importer of oil from OPEC producers. Consequently, the financial hegemony enjoyed by the IPE and NYMEX would be greatly challenged and thus the U. S is likely to avoid this through military action. 3. 0 The Ambitious Nuclear Program of Iran The Tehran’s nuclear ambition is another possible reason as to why the U. S may launch a land military attack on Iran. This has been seen from the latest series of sanctions on Iran by the Obama administration which mainly targets the Islamic Revolutionary Guards Corps which is the most powerful social, political and economic institution in Iran. The organization also has a large number of companies and banks and therefore makes it an appropriate target for these sanctions (LANDLER COOPER, 2010). However, the critical thing to focus on with regard to this issue is whether these sanctions have the capacity to compel Iran to halt its nuclear program. If the history of political and economic sanctions against countries is anything to go by, then Iran may not change its course despite the sanctions and this may lead to war. The reason for the sanctions is to â€Å"contain† Tehran which depicts a link which leads from diplomatic pressure to military action (Nadal, 2010). Tehran views this threat as real considering that its two neighbors to the west and to the east have a large number of U. S troops. 4. 0 Conclusion A possible military action on Iran by the US cannot be overlooked since the reasons surrounding this possibility would also have major effects on the economy and the security of the US. Considering the economic problems facing the US, the attempts by Iran to establish the euro-based oil bourse may seem as an attempt to suppress the dollar in the international oil market. The nuclear program also would threaten the security not only of the US but also of the world if it is not either regulated or completely halted. To aver the nuclear weapons development, Washington ought to try and alter the perceptions of threat harbored by Iran against America. References Clark, W. (2004).

A Review Of Acheson Report Health Essay

A Review Of Acheson Report Health Essay The report also calls for more funding support to schools in deprived areas, better nutrition and the concept of health-promoting schools. Benefit levels for providing nutritional meals to children should be increased and food should be more affordable for fulfilling nutritional needs of children. The report also focuses on smoking and drinking problems urging for restrictions on smoking in public places, a ban on tobacco advertising and promotion, mass educational initiatives, increases in the price of tobacco and the prescriptions for nicotine replacement therapy. The Acheson report also suggests close links between health and mortality rates. The Acheson report has been instrumental in shaping, directing and implementing several changes in the NHS Health policy. Several studies and research reports have been published on the impact and influence of the Acheson report on changes within health care policy. The Acheson report identified three crucial areas on social gradient and health inequalities and suggested that: a high priority should be given to the health of families with children; all policies likely to have an impact on health should be evaluated in terms of their impact on health inequalities; steps should be taken to reduce income inequalities and improve the living standards of poor households. The Acheson Report and UK Health Policies The Acheson Report 1998, an Independent Inquiry into Inequalities in Health was similar to the Black Report 1980 and can be considered as a Department of Health review of the evidence on inequalities in health in England. The Department of Health has responded to the Acheson report by taking an official course of action. The Department of Health mentions that tackling health inequalities is a top priority for the Government, and is focused on narrowing the health gap between disadvantaged groups, communities and the rest of the country, and on improving health overall. The strategy for addressing this problems is published in, Tackling Health Inequalities: A Programme for Action that lays the foundations for meeting the Governments target to reduce the health gap on infant mortality and life expectancy by 2010.A programme for action include a three-year plan for tackling health inequalities and to help local organisations improve the way services are delivered to disadvantaged groups. The programme for action in response to the Acheson report is based on: Supporting families, mothers and children Engaging Communities and Individuals Preventing Illness and providing Effective treatment and Care Addressing the underlying determinants of health The Acheson report suggests that socioeconomic inequalities in health and expectation of life have been found in England for many years and there have been data identifying differences in longevity by ones socioeconomic position. Inequalities of health are measured in terms of mortality, life expectancy or health status and could be categorised by socioeconomic status, ethnic group or gender. The Acheson report suggested that there are differences in the health status of mothers, babies, people of lower socioeconomic status and people who smoke or drink heavily. The report definitely shows that death rates are falling in England and the rates have fallen since 1896. Thus life expectancy seems to have risen in the last few years although healthy life expectancy has not been rising. In fact the proportion of people with long standing illness has risen from 15 percent to 22 percent (Acheson Report, 1998). The Acheson report thus gave new insights on health policies and identified issues that contribute to an increased rate of mortality and possible ill health. It identified several socioeconomic determinants including income distribution and household below average income, education, employment, housing, homelessness, public sector, transport and health related behaviour. Following the report, the Choosing Health White Paper given by the Department of Health sets out the key principles for supporting the public to make healthier and more informed choices in regards to their health. Through the paper, the Government has provided information and practical support to get people motivated and improve emotional well-being and also provide access to services to encourage people to make healthy choices. The government has also drawn up a food and health action plan that focuses on the ways that better health can be achieved through better nutrition at all stages of life and for different groups in society, recognising and addressing different needs, particularly those of disadvantaged groups (Choosing Health, DH, 2004). The government has also set up the Health Improvement Plan and a new NHS plan for tackling health inequalities 81% of people in higher socio-economic groups consider themselves to be in good health now, compared with 61% of people in the lowest groups 76% of people in the higher groups expect to be in good health in 10 years time, compared to 53% of people in the lowest groups (DH, 2004). Putting forward the NHS improvement plan, the Government reiterated the NHS commitment that the NHS is motivated to prevent disease and improve health in general. The Government policies are focused on the fact that inequalities in health cannot be accepted and the fundamental objective is to create healthier choices for disadvantaged groups. The NHS Improvement plan was laid down in 2004 to not only counter health inequalities but also provide better quality of care to patients and provide safer and more effective treatment. The NHS Improvement Plan set out modernisation and health plans putting patients and service users first through more personalised care; a focus on the whole of health and well-being, not only illness; and further devolution of decision-making to local organisations. (DH, 2004) According to the Government report and Action Plan laid out in then Choosing Health White paper the nutritional priorities were given as follows: increase in the average consumption of a variety of fruit and vegetables increase in the average intake of dietary fibre to 18 grams per day reducing average intake of salt to 6 grams per day reduce average intake of saturated fat maintaining the current trends in reducing average intake of total fat reducing the average intake of added sugar (Choosing Health White paper, 2004) The Government took several steps to ensure that the recommendations of the Acheson report is considered for any further changes within the NHS. Accordingly major steps have been taken to ensure consumer awareness on the consumption of healthy foods and development of good food habits. Reducing the proportion of fat, salt in the diet has been recommended and retailers and caterers have been asked introduce healthier range of foods and offer such foods in convenient stores, centre locations and in remote areas of the city. In a plan to tackle health inequalities, the Government has focused on many plans including Offer people personal health plans with support from the NHS. Recruit NHS health trainers to provide advice and support for people to develop their personal health plans. Provide services in the areas of highest need. Offer disabled people the option of taking up a health check. (DH, 2004) Considering the Acheson report on the exaggerated problems of health care among pregnant women and children, the government has also provided eligible pregnant women with vouchers that can be exchanged for fresh fruit and vegetables, milk and infant formula through a new scheme called Healthy Start. A Sure Start scheme is also in place for providing training, guidance and support for early years to children. Practitioners encourage changes in parental behaviour and improve the social and emotional development and physical health of children in the early years. Community Parental Support Projects are also in place that involves training of lead workers in 500 communities. Healthy Schools programmes are encouraged to target deprived schools including Pupil Referral Units. The Government has promoted the concept of healthy schools by 2006, working towards a healthy school status by 2009. The concept of Healthy schools, Sure Start and the Concept for providing Parental Support as well as providing people with personal health plans are some of the steps that the government has taken to ensure the promotion of health. Some of the objectives of the Action Plan have been given as follows. Following the Acheson report, the government focus has shifted from the one aimed to meet national targets to a different approach that could be given as follows: standards are the main driver for continuous improvements in quality; there are fewer national targets; there is greater scope for addressing local priorities; incentives are in place to support the system; and all organisations locally play their part in service modernisation. (Care Standards Planning Framework, 2004). Research Studies We discuss several studies which deal with the Acheson report. Oliver and Nutbeam (2003) point out that health inequalities has been considered seriously for an approach to improve health care and government policies have been developed to explicitly address existing health inequalities that has become an important issue since Labour has returned to power in 1997. The development of health inequalities policies, have been critically examined to assess how such policies could or should be developed. The authors point out that progress in the development of health inequality policies has been made although the progress is less than expected or ideal. Kisely and Jones (1997) have written on the issues of public health ten years after the Acheson report. They point out that the issue of communicable disease control and the role of public health medicine is of considerable concern in the light of outbreaks and NHS reorganisations. The Acheson report seems to have highlighted several issues in this regard. Yet as Kisely and Jones the Reports findings have yet to be fully implemented. The paper calls for a further review of public health function and should include the removal of the specialty from management costs, and the clarification standardisation of the roles of the Director of Public Health (DPH), CPHM and other members of the multi-disciplinary public health team (Kisely and Jones, 1997). Possible organisational implications for a public health approach have also been suggested. Tarlov (1999) has delineated four conceptual frameworks providing the bases for constructing public policy strategies for improving population health and this include: (1) Determinants of population health. (2) Complex systems: (3) An intervention framework for population health improvement. (4) Public policy development process with two phases of public consensus and policy action. The Acheson report can be judged in this context and has provided both a consensus and a policy framework. Back to: Essay Examples Conclusion: The research studies and analysis of the Acheson report suggests that the 1998 Acheson report has been extremely influential in shaping Health care policies in the UK and reducing inequalities in health.

A power amplifier

A power amplifier Introduction: A power amplifier is an electronic device that changes the magnitude of a signal. It is usually used to transfer high power to a low output load such as speakers where there load is about 8 ohms [1]. The relationship between the output and input is called the transfer function. An important aspect of the amplifier is the gain. The gain is the ratio between input and output whether this input is current, voltage or power. Therefore, the gain does not have a unit. The quality of the amplifier is determined by many aspects, which are gain, bandwidth, efficiency, linearity, noise and others. As one of these characteristics increase the others may decrease. Therefore, the amplifier will be designed to meet the required specifications determined by the application for which it will be used for. The various designs of the amplifiers are classified into many types which include A,B,C,D and some other types derived by combining the basic ones such as class AB which is obtained from class A and class B pertaining to their efficiency and linearity [1]. Ideally, power amplifiers are supposed to deliver 100% of the power to the load. However, as some of the power dissipates in the components of the amplifier, hence we do not have ideal power amplifiers. It is found that the linearity has an inverse relationship to the efficiency of the amplifier. The classes A, B and C power amplifiers are considered inefficient but linear whereas the other types are considered efficient but more complex than the basic types. Class A power amplifiers are least efficient than the others. The efficiency of class B is much higher than class A, however, class C has the highest efficiency level compared to class A and B [2]. The scope of this paper is to discuss class B power amplifier in details. Class B power amplifier: This class of amplifier was developed in order to improve class A power amplifiers, which have low efficiency rating. [1-3] shows and explains the internal design, the efficiency, the advantages and disadvantages, and the applications of class B power amplifiers. Internal circuit and operation: To get a sufficiently good amplification of the input waveform in the output, a push-pull class B power amplifier configuration must be used. This configuration is based on two transistors. The term push-pull comes from the fact that two transistors in a class B amplifier conduct in alternating half-cycles of the input [1]. Moreover, there are two types of push-pull configurations, one with transformers and one without transformers [2]. A balanced centre tapped input transformer is used to split the incoming waveform signal into two equal cycles that are 180 degrees out of phase with each other. Another center-tapped output transformer is used to recombine the signals. If the transformer is ideal we can get two collector currents that flow in opposite directions, hence no magnetization of the transformer core takes place which in turn minimizes the distortion in between the two signals. Both transistors used are of NPN transistor type where their emitter terminals are connected together [2]. discusses the mechanism in which the circuit works. Primarily, when no input signal is present, both transistors are biased at cutoff. When a signal is present during the positive half cycle, the transistors base inputs are in anti-phase to each other which causes transistor TR1to become biased above cutoff due to the positive base input that drives a large collector current, while TR2 is still biased at cutoff as the base current will go negative, making the collector current decrease by an equal amount of the increase in the collector current in TR1. This will result in an amplified positive-output half cycle. When the input signal is in the negative half cycle, the same procedure is done but in opposite, resulting in TR1 returning to the cutoff state while TR2 start building until it becomes biased above cutoff. This will result in an amplified negative-output half cycle. The half cycles combine to produce an output amplified 360 degrees signal with distortion. This effect is the push-pull effect. Advantages and Disadvantages of Class B power amplifier: Class B amplifiers have an advantage over class A amplifiers which is that the collector current is zero when the input signal to amplifier is zero that cause no power dissipation in the quiescent condition which leads to higher efficiency [1]. The main goal of using power amplifiers is to generate maximum AC power to the load, while consuming the minimum DC power possible from the supply. The efficiency of class B amplifiers in all types may reach up to 75% which is much higher than class A amplifiers [2]. The equation shown above is used to calculate the percentage efficiency of all power amplifiers. Pout is the power delivered to the load and PDC is the power taken from the supply. Class B amplifiers has one main disadvantage which is the high distortion that occurs in the output signal. This type of distortion is called the crossover distortion [2]. This distortion occurs when the transistors are switching over from one to another. Each transistor requires minimum voltage VBE which is about 0.7V to conduct. When one transistor is turning off by having VBE less than 0.7V and the other transistor is turning on but still the input voltage is not greater than VBE, the resulting is a zero voltage â€Å"flat spot† on the output wave shape as it crosses over from one half of the waveform to the other [2, 3].According to [2], the crossover distortion cause a reduction in the overall peak to peak value of the output waveform causing the maximum power output to be reduced. Hence, class B power amplifiers today are not used in many applications; it is only used as an audio amplifier. There are many ways to get rid of crossover distortion effect, but the most commo n one is to bias both the transistors at a point slightly above their cut-off point [1, 2]. This will lead us to class AB Amplifier circuit which is out of this paper scope. Application: The cost of class B amplifier is not high; therefore it is used in low budget designs. Furthermore, it is used in designs where the quality of the sound is not important because of the distortion it provides [3]. However, class B amplifier is preferred in designing audio power amplifiers [3]. [3] reveals that most of the time the music will be low so the signal will act as if it is in class A region. This means that the distortion will not be that bad. Moreover, the distortion can be minimized by using a negative feedback loop [3]. [3] also emphasizes that the sound power produced by this amplifier is huge and it can be run without heat sinks. Conclusion: This research was conducted in order to investigate the properties of class B power amplifier. First an overview about power amplifiers was considered in order to develop a better understanding about the reasons behind classifying them to many types. It was found that each class has its own application which it suits for. This is determined according to many aspects such as linearity and efficiency which are inversely proportional. Class B was found to be higher in efficiency compared to class A but less in linearity. Looking into the configuration of class B, it was found that class B amplifier has two possible configurations, one with a transformer and the other without the transformer. Both configurations works with two transistors where each one conducts for a half cycle (180 degrees), which gives the opportunity to the other transistor to cool. However, the configuration where the amplifier does not have a transformer is more efficient because less energy is lost in elements as a result of eliminating the transformer core. Class B amplifier was found to be used in low cost designs and designs where the clarity of the voice is not important. The crossover distortion can be removed by using a negative feedback loop or bias both transistors at a point slightly above their cut-off point, which is the idea of class AB power amplifier.

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

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

Society and Femininity Essay -- American Literature Essays

Society and Femininity: Triumph of the Human Spirit Very few novels in American Literature can earn the title of timeless. These novels transcend the ages, because they possess a greater meaning. Their stories teach people about life, the glory of the human soul, and all it can endure to overcome. Three novels in particular get to the very heart of feminine struggle. Though they touch not on women’s struggle to vote, they reach the higher plain of women’s struggle to be seen as who they are and not what society wants them to be. To Kill a Mockingbird, The Color Purple and The Bluest Eye all deal with the topic of women trying to overcome society. Although these novels were written in the mid to later half of the twentieth century, they go back to a time when the Great Depression was touching all walks of human life. Each of the main characters in these novels does not fit society’s view of femininity during the time period. Although the main characters in the three stories do not fit society’s idea of femininity, they each, in their own way, overcome this and show a greater beauty of strength. All three main characters in each of these stories fail to fulfill society’s idea of beauty and femininity. The lead character of To Kill a Mockingbird, Scout, is a nine year old tomboy, during a time when girls aren’t supposed to be tomboys. She receives much criticism by her aunt and many others for not being the ideal young little girl. Harper Lee, the author, expresses through the view point of Scout, â€Å"Aunt Alexandra was fanatical on the subject of my attire. I could not possibly hope to be a lady if I wore breeches, then I said I could do nothing in a dress, she said I wasn’t supposed to be doing things that requi... ... is not willing to give up the fight by her amazing desire to want that child to live. Although the book does not show Claudia in adulthood, one can envision her as the epitome of a strong woman. These three main characters defy society because of their strength. These books become timeless because of the female characters. Each novel defies the expectations of society in its own way. They exemplify women who rise above the average to become greater than what most people are. The novels show the female spirit in all its glory; they portray its strengths and ability to overcome obstacles. Works Cited Lee, Harper. To Kill a Mockingbird. 1960. 40th Anniversary Ed.

Reaction between Valine and Serine

A DNA (deoxyribonucleic acid) is composed of 4 different bases; adenine (A), guanine (G), cytosine (C) and thymine (T). Applying these 4 bases it may contain thousands of sequences within a single strand. Each of these bases makes a specific pairing with a corresponding base whereby the double helix structure is synthesised. This interaction is called base-paring and the complementary base pairs are; T pairs only with A and C only with G. Through this simple coding language, the DNA carries and represents its vast genetic information.Through a process called transcription, the genetic information of DNA is copied to form an intermediary molecule termed ribonucleic acid (RNA/messenger RNA). This formation is synthesised in the same way as DNA replication. However this process occurs only on one DNA strand called template strand. Thus the mRNA is only a single strand with 4 bases; adenine (A), guanine (G), cytosine (C) and uracil (U). The base-pairing rules are,DNAmRNAGC CG TA AUThis w ill be synthesised through enzyme RNA polymerase and happens in the nucleus of the cell.This transcribed mRNA consist the genetic code, which is used to generate proteins in the following process called translation. This code is comprised of triplets that specifies an amino acid (e.g. AUG for methionine) and named as codon. These codons are recognised by transfer RNA. T-RNA can bind specific amino acid on one side by means of enzymes and has got an anticodon consists of triplets on the other side. Each amino acid has got its own tRNA. The 1st mRNA codon will be always AUG, the start codon. Once the 2nd  amino acid is bound to the 1st one, the 1st tRNA will be released and the 3rd one follows. This process is repeated until the so-called stop-codon in the mRNA terminates the growing protein synthesis. The completed protein is then released and takes its own characteristic shape. This process occurs in the cytosol of the cell.The four-character language of DNA/mRNA can be converted into 20-character language of protein. However there are 64 combinations of mRNA codons as there are 4 possibilities for the 1st codon and 4 for the 2nd and 4 for the 3rd (4 x 4 x 4 = 64). Certainly there are many codons for many amino acids; however some are not, for instant stop-/start codons.
