The U-2 Program Was Started Because The U.S. Needed To Have Informatio

U2 The U-2 program was started because the U.S. needed to have information about the Soviet nuclear capacity (The Long Peace 197). Many people believed that the Soviet Union had many more missiles than the United States did (Mayday 154). The Democrats, especially Lyndon Johnson who was head of the Senate Military Preparedness Committee, believed that there was a missile gap between the U.S. and Soviet Union (Mayday 237). Khrushchev claimed that the Soviet Union was cranking missiles out like sausages (Mayday 152). Eisenhower did not want to start an arms race. He believed that the greatest threat to national security was to be frightened into an arms race which could lead to nuclear destruction (Mayday 152). In 1954 C.I.A. Director Allen Dulles said that there were serious shortcomings in the accuracy of our intelligence regarding Soviet military capabilities(The Long Peace 197). In response to this, Eisenhower set up a secret Technological Capabilities Panel to develop ways to American History

Learn More About Georg Ohm and Ohms Law

Learn More About Georg Ohm and Ohm's Law Georg Simon Ohm was born in 1787 in Erlangen, Germany. Ohm came from a Protestant family. His father, Johann Wolfgang Ohm, was a locksmith and his mother, Maria Elizabeth Beck, was the daughter of a tailor. Had Ohms brothers and sisters all survived he would have been one of a large family but, as was common back then, several of the children died young. Only two of Georgs siblings survived, his brother  Martin  who went on to become a well-known mathematician, and his sister Elizabeth Barbara. Although his parents had not been formally educated, Ohms father was a remarkable man who had educated himself and was able to give his sons an excellent education through his own teachings. Education and Early Work In 1805, Ohm entered the University of Erlangen and received a doctorate  and immediately joined the staff as a mathematics lecturer. After three semesters, Ohm gave up his university post. He could not see how he could attain a better status at Erlangen as prospects there were poor while he essentially lived in poverty in the lecturing post. The Bavarian government offered him a post as a teacher of mathematics and physics at a poor quality school in Bamberg and he took up the post there in January 1813. Ohm  wrote an elementary geometry book while teaching mathematics at several schools. Ohm began experimental work in a school physics laboratory after he had learned of the discovery of electromagnetism in 1820. In two important papers in 1826, Ohm gave a mathematical description of conduction in circuits modeled on Fouriers study of heat conduction. These papers continue Ohms deduction of results from experimental evidence and, particularly in the second, he was able to propose laws which went a long way to explaining results of others working on galvanic electricity. Ohm's Law Using the results of his experiments, Ohm was able to define the fundamental relationship between voltage, current, and resistance. What is now known  as Ohms law appeared in his most famous work, a book published in 1827 that gave his complete theory of  electricity. The equation I V/R is known as Ohm’s Law. It states that the amount of steady current through a material is directly proportional to the voltage across the material divided by the electrical resistance of the material. The ohm (R), a unit of electrical resistance, is equal to that of a conductor in which a current (I) of one ampere is produced by a potential of one volt (V) across its terminals. These fundamental relationships represent the true beginning of electrical circuit analysis. Current flows in an electric circuit in accordance with several definite laws. The basic law of current flow is Ohms law. Ohms law states that the amount of current flowing in a circuit made up of only resistors is related to the voltage on the circuit and the total resistance of the circuit. The law is usually expressed by the formula V IR (described in the above paragraph), where I is the current in amperes, V is voltage (in volts), and R is the resistance in ohms. The ohm, a unit of electrical resistance, is equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals.

Case Report - Assignment Example One major factor that has contributed to the emergence of Apple as the global market leader in consumer electronics is a paradigm shift that took the company in a whole new direction (Parr, 1992). The new paradigm is founded on the principle that an organization’s management must focus on two most important facts. Firstly, there is need to focus on finding out what is valuable for customers in terms of the products and services that an organization has to offer (Parr, 1992). Secondly the management has to be involved in the process of creating as well as continuous improvement of the organization’s super system (Parr, 1992). As such, Apple’s management has been effective in all these aspects in terms of bringing the company to a desired future as well as endearing itself to the customers. Therefore, Apple’s SWOT analysis from the case study can be assessed as follows, among the company’s strengths include having a well informed and robust management that has taken a leading role in driving forward the company’s agenda. Similarly, The Company has a huge workforce that is highly skilled and capable of implementing the firm’s strategic plan. On the other hand, the company’s operation has also faced challenges due to the company’s weaknesses, including its expensive products that are often out of reach for most customers. Furthermore, the company’s systems are incompatible with other available systems, making it quite difficult for one to adopt a new system from Apple. Among the company’s opportunities include the growing market share, ability t o maintain an innovative culture and the company’s position as the market leader. Conversely, several threats such as emerging competition and substitute products can also affect the company‘s

The Talented Tenth, by William Edward Burghardt [W.E.B.] DuBois, 1903 Essay

The Talented Tenth, by William Edward Burghardt [W.E.B.] DuBois, 1903 - Essay Example Furthermore, the viewpoint would most likely be somewhat anti-American – this is because he renounced his American citizenship towards the end of his life, and he also was decidedly anti-capitalist, becoming a member of the American Communist party while he still lived in America. All of this would point at a man who was not comfortable in his birth country, not comfortable with the economic circumstances of the country, not comfortable with the economic basis of the country's financial system, and not comfortable with whites, in general. Yet, he was also a person who was passionate about helping blacks become the best that they can be and passionate about assuring that blacks were economically, politically, and civilly on par with the whites in America.1 Discussion The document titled â€Å"The Talented Tenth,† which is the topic of this essay, is a primary source. While the book that features this particular writing, titled W.E.B. Du Bois Writings (1986), is a seconda ry source because the book itself was compiled by somebody other than W.E.B. DuBois. The article itself is primary because it was written by W.E.B. DuBois himself. If somebody had written about the ideas of W.E.B. DuBois, then this would be a secondary source. The actual writing is primary. The gist of the article is that the black race must be saved by ten percent of the black population, that is, the most talented among the population, and they must be developed so that they could become the best and lead the worst away from â€Å"contamination and death.†2 The problems and solutions of the article are complex. One of the problems is that there must be strict training for the talented tenth, and the object of training these men must be something other than economic or technical training.3 DuBois states that training these men only in economic or technical skills would be reductive and would not result in these individuals becoming men: â€Å"If we make money the object of man-training, we shall develop money-makers but not necessarily men; if we make technical skill the object of education, we may possess artisans but not, in nature, men.†4 The solution to this is that the men would attain higher education that would provide them a well-rounded education – education that would not only increase their intelligence but also their sympathy and their knowledge of the world. DuBois also wrote that prejudice, in general, is a problem. That the whites in America believe that the blacks who are talented and intelligent, who are leading the black race, are the exceptions. As a rule, according to the white race, the blacks are purveyors of â€Å"death, disease and crime.†5 The solution that DuBois proposes is that the best and most capable of the black youth would be schooled at the best colleges and universities. DuBois acknowledges that society has the potential to be â€Å"pulled down† by the worst elements of the black race, whic h would fulfill the white's view that the blacks are ruled by those who are the transmitters of crime, disease and death, but his solution is that the blacks must be lifted up through the talented few who will be trained at these colleges and universities. Judging from the biography of W.E.B. DuBois, the assumptions were mostly borne out through

Providing quality care - Essay Example In countless regions in the world, nursing programmes are aimed at increasing proficiencies that assist nurses in handling particular nursing/care needs (Fitzpatrick Kazer 2012, p. 54). This paper will examine some of the behaviours, attitudes, and abilities necessary to become a professional nurse, and some of the elements that are crucial in the nursing field. . The progress witnessed in different regions in terms of healthcare has seen the role of the nurses become a major game changer in the medical field. The nursing fraternity has a framework in which all the actions and duties are reflected that aid in the protection and assistance of all individuals in need of medical care. The ethical and professional behaviours that nursing personnel are meant to exhibit should also reflect the attitude and organizational culture of their respective organizations (Fry & Johstone 2008, p. 37). This is done to make sure that the nursing profession maintains the professionalism and attitude that is needed in catering to the needs of people in society, and the overall good of the medical practice. Nursing requires an individual to have what may be considered the 6Cs, which are; compassion, care, courage, commitment, competence, and communication. They assist nurses to engage positively and professionally with all those meant to be in their care. All these behaviours are crucial in nursing because they assist nurses in understanding their patients and treating them professionally (Goodman & Clenmow 2010, p. 57). Care defines how nurses are meant to carry out their duties. It needs to be constantly and consistently provided at every stage. Compassion is paramount when it comes to understanding the predicament in which their patients are in, and what may be done to assist them. Compassion looks into how care is delivered to those in need. Competence comes into play when a nurse understands and comprehends the nature of the individual in

Examining Concepts Of Leadership And Reflection In Nursing Essay

Examining Concepts Of Leadership And Reflection In Nursing Essay Western (2008) says that, the term leadership has different meanings and we will aware of leadership when we see it. By the estimates of Durbin (2000), in academic literature there are 35,000 definitions for leadership (Pye,2005;P.32). According to Stodyill (1974;p.257), there are as many people tried to define the idea of leadership as many definitions of leadership as there are. Hemphil and Coons (1957,p.7) defined leadership as the behaviour of an individual directing the activities of a group toward a shared goal. Clark (2009) says that the change in the definition of leadership occurs according to the person, whom we ask to define the term. Houser and Player (2004) concluded in their study of a dozen nurse leaders as that, the nurse leaders have some common characteristics such as innovative, courageous, visionary, scholarly, resilient, creative, committed, responsive, and thoughtful. Tan (2006) suggests that the concept of leadership as, to influence a person or follower, to do what is critical to achieve societal and organizational goals. Nurses are particularly aware about the necessity of reflective practices among health care professionals (Duffy,2007;Manthey,2001, et al.). Same as that practice of reflective leadership have an equal importance in this profession (Deutsch and Sherwood,2008). Oestreich (2009) says that, reflective leaders must know about, how they are opening paths for clear communication and goal fulfilment, where they are in the progress of their own and organizational goals, and how they connect with others. Great leaders have to walk alone sometimes, such aloneness can facilitate reflection(Drucker,1996,p.9). Qualitative researchers says that , more distant reflection is possible through the observation of the participant. In a nutshell, both the individual leader, more than that the organization benefited by the reflective practices. LEADERSHIP CHARACTERISTICS According to Nanus,B (1985), integrity, passion, and vision are the fundamental characteristics of a good leader. Sociability, integrity, determination, self-confidence,and intelligence are the characteristics belong commonly to leaders (Stodgill,1948,1974). Research among 46 magnet hospitals clearly defined the value of leaders as they are knowledgeable and supportive, enthusiastic and visionary, have expectations and high standards, value professional development and education, demonstrate status and power in the organization, are responsive and visible, are active in professional associations and communicate openly (Mc Clure Hinshaw,2002;Scott et al,1999;Kramer,1990;Mc Clure,Poulin,et al,1983;Kramer Schmalenberg,2005). Murphy and DeBack (1991) identified nurse leader have leadership characteristics such as learning and taking initiative, designing organization structure, mastering change, and managing the dream. LEADERSHIP THEORIES Many leadership theories are useful to nursing (Burns,1985). By Patricia Kelly (2010) the major leadership theories classified in to the following approaches: Behavioural, contemporary, and contingency approaches. BEHAVIOURAL APPROACH In behavioural approach the leadership studies by Kurt Lewin et al.(1930) gave information about three widely existing leadership styles. That are autocratic, democratic, and laissez-faire leadership styles. Autocratic style of leadership the opportunity to make decisions centralized in the leader and the leader has the power to control and command the team members. In democratic style the team members have the authority to take decisions and there is a close inter personal relationship between the leader and the individual team members moreover there is sharing of opinions. By Lewin (1939) laissez-faire leaders postpone decision making and are characterized by freedom of behaviour. In this group the negative points are the low productivity and the feeling of dissatisfaction. CONTEMPORARY APPROACH This approach gave importance to the development of learning organizations and lead the process of transforming change. Charismatic theory, transformational leadership theory, knowledge workers, emotional intelligence, and wheatleys new science of leadership are under this approach (Kelly,P,2010). CONTINGENCY APPROACH In this theory the factors in the environment influences the leaders outcomes. This approaches include the situational theory of Hersey and Blanchard, Feilders contingency theory, path goal theory and the idea of substitutes for leadership Among these theories one theory that has become relevant to nursing is the transformational leadership theory (Burns,1985). Transformational leadership is defined as, One who inspires and empowers everyone with the vision of what could be possible(Hood,2010,p.460). The suggestion by IOM (2003,b) is that,the transformational leadership acts as a safety net for the patients. According to Clark (2009,p.17) transformational leadership and authentic leadership are the two different types of leadership styles significantly important for nurses. THE IMPORTANCE OF REFLECTIVE PRACTICE IN NURSING LEADERSHIP The maintenance of a personal professional profile is important for the attainment of maximum reflection in education and practice after the registration of a practitioner, by UKCC. The regularly recording of daily events and preplanned learning activities as a part of reflective process are the bias of this profile (UKCC,1997). One of the inevitable processes in clinical supervision is the reflection. Moreover, clinical supervision helps the practitioner to up bring the standard of care and thus it support in their practice (UKCC,1996). REFLECTION The concept of reflection is difficult to define (James Clarke,1994;Clarke et al., 1996). John Dewey (1933,p.9) defined the term reflection as active, persistent, and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends. By Dewey (1933) the application of scientific methods are possible through experimentation and reasoning and there by challenge and test out true beliefs. His studies influenced the educational ideas and work of Schon,D (1983,1987); Boyd Fales (1983); and Boud et al.(1985). According to Boyd Fales (1983) reflection is the process of internal examination and exploration of a concerned issue, by an event, that self clarify and creates meaning and resulted in a different conceptual perspective. In definitions of reflection, most of them support the ideas of intellectual skills and creativity development, self awareness raising, and new knowledge development (Hancoc k,P,1999). By Boud et al. (1985), to becoming a reflective practitioner, one should consider an issue, triggered by an experience, go back through it, and ponder over it and then they will get a new insight about that particular situation. TYPES OF REFLECTION Schon (1987) noticed two types of reflection in his studies. Reflection-on-action and reflection-in-action. He identified that practitioners use reflection, when they met with unique situations, when they may not be able to use previously learned theories or techniques by formal education. By the concept of his reflection-on-action, to develop as a practitioner or person, critical thinking and construction and reconstruction of events are important. On the other hand, by his reflection-in-action, action from a practitioner reshaped due to his thinking while he is doing it and with out disturbing it. SKILLS NECESSARY FOR REFLECTION By Atkins Murphy (1993) the skills such as description, synthesis, evaluation, judgement, critical analysis, and self-awareness are necessary for reflection. Front-runners in nursing have established some models of reflection, significantly those of Schon (1983,1987); Kolb (1984); Boud,Cohen et al.(1993); Boud,Keogh et al.(1985); and Johns (1992). Their levels of explanations are different, while the retrospective phenomenon of reflection has three fundamental processes. That are retrospection, reorientation, and self-evaluation (Quinn,F,M,).DATE MODELS OF REFLECTION à ¢Ã¢â€š ¬Ã‚ ¢ Reflective Practice was introduced by Donald Schon in his book The Reflective Practitioner in 1983.   There are different models of reflection in practice.   In that I would like to discuss about the two models of reflection Gibbs model, 1988 Johns model, 1995.      GIBBS MODEL OF REFLECTION 1988 Gibbs model is a cyclic process of reflection, in that a practitioner describes the experience and must evaluate and analysis of how they were feeling during the experience.   By the evaluation and analysis of the emotions associated with the situation give the practitioner a chance to understand the situation and come to a conclusion of what else could be done, or what other options could have been taken.   Most importantly,in Gibbs model of reflection the final stage is the formulation of action plan, that give an idea about what actions would be taken if the situation happened again (W http://en.wikipedia.org/wiki/Reflective_practice). JOHNS MODEL It is a structured mode of reflection that provides a practitioner with a guide to gain greater understanding.   In this model of reflection, reflection carried out through the act of sharing of emotions with colleague or a mentor and it provides a faster rate of learning than reflection alone.   In order to achieve reflection looking in on ones thoughts and emotions and looking out at the situation experienced are important steps in this model of reflection.   Mainly five patterns of learning are included in to the guided reflection, that are the practitioners analysis about the aesthetic, personal, ethical, empirical, and the reflexive elements experienced through the situation. REASONS TO PREFER JOHNS MODEL OVER GIBBS MODEL I think Johns model of reflection is better than that of Gibbs model because, in Johns model practitioner get an opportunity to share with a colleague or mentor, about their thoughts and emotions of their own and about the situation experienced.   It seems to me that by the sharing of emotions definitely, we will get a clear cut idea about the feelings of the self and about the situation in a faster rate. Looking in and looking out become easier when the structured questions shared between a colleague or an experienced person.   In Gibbs model of reflection, evaluation and analysis of the emotions associated with the situation experienced is important and there is no sharing of ideas or emotions with anybody.   I feel that with out the sharing of emotions reflection occurs in a slower rate.

Gmos and Organic Food

October 30 2012 Similarities and Discrepancies between GMOs and Organic Products encompass analyzation Why spend more money on organic food? Why are GMO products lasting longer? These are commonly asked questions which will be explained. By the definition of GMO products, they encompass alimentary products grown from seeds that have been genetically altered. Organic products are those that are grown under the traditional way, without any intervention of Bio-engineering, and also without the usage of chemicals, known as pesticides.The Author, Michael Pollan in both, â€Å"Omnivore’s Dilemma† and â€Å"In Defense of Food† makes an extensive and detailed analyzation of the production of food now days. The big corporations (farms) are now known as manufacturing factories; where practically all the elements of their production process are strictly controlled. This highly technological system reduces the nutritional value of their products and in many cases their flavo r as well, but it guarantees high volumes and longer shelf life of the products.An example of a food that would be known as a GMO would be tomatoes, which would be less healthy and again it wouldn’t taste the same as an organic one. Organic products are grown by small farmers according to old farming techniques. These products do not need the addition of micronutrients like GMOs; they maintain all the nutritional values and the original taste. Unfortunately, small farmers can not satisfy the demand that the market needs, let alone, the prices are higher. For example, if you were to sell organic tomatoes, you would have to need to sell them locally.If a company such as organic valley were to be ship organic products from California to New York, with them having shorter expiration date, they would end up going bad. It would be hard for everyone to have the budget to buy and eat organic food; even expensive restaurants don’t use organic food. So, what is better? Feeding a large growing population with GMO products; or to go back to square one, and run the risk of not having enough supply and have the prices skyrocket. At the end of the day, people will eat more GMO food for not everyone has money to buy organic food.

Media Landscape in the World

Media Landscape in the World The New Modern Media October 12, 2012 The New Modern Media Watching TV while having morning coffee, listening radio on the way to work, checking Facebook before work, tweeting in the lunch break, and googling information related to work; that is the way the new modern media has changed our lives. To understand the term modern media more, Debashis Aikat(n. d. ), Associate Professor and Media Futurist, has come up with a definition, â€Å"Modern media refers to mass communication characteristic of recent times, or the contemporary communication relating to a recently developed or advanced technology(Aikat, n. . )† So that basically means that modern media is the media which is connected to new technologies. Nowadays that is so easy to access different kinds of modern media; however, this new type of media continuously excludes different groups of people. We are used to say that is so easy to access the internet. Just take your computer, tablet, or Sm artphone and you are connected. Wait! How many people are not able to do that? To have the connection, the basic thing we need is electricity. We need to charge all of the devices in order to use them.According to a newspaper Arabia 2000, in the year 2011 about 20 percent of world’s population still lived without electricity(Arabia 2000, 2011). So these people are totally excluded from the modern media. Actually, the number is even bigger. Because electricity is just the basic thing we need. But there are people who have electricity, but they cannot afford the devices to be connected to internet. Some could argue that all kind of media cost, and old media is even more expensive because, for instance, newspapers do not have that much of information but cost almost a dollar a day.There is a difference if you have to pay a dollar whenever you decide to have a newspaper or you have to spend a few hundred dollars for device, and then you have to get the internet connection, and of course pay for electricity. Not only people with a low income are excluded from access to new media. Age and religion can be the reason why people stick to old media as well. If I ask my grandma to turn off my computer, she would get scared because she would see that computer is not connected to electricity but still works.She is used to see calculator which has to be connected to electricity. There are many older people who have no ideas how to use new devices. Martin Beckford(2011), the journalist of the news website â€Å"The Telegraph† in his article writes, â€Å"A charity report found that older people have trouble getting information about public services, such as details of libraries and public transport, because so much of it is kept online(Beckfors, 2011). † This article truly shows that because of the changes in media older people are isolated from the world.People could say that when the next generation gets old, that is not going to be a problem anymore. I do not agree with that. Technology changes even faster than people get older. These are the people who do not know how to use devices, but there are also people whose believes do not allow using new technology. For example, in some places in the world we can still find groups of people called Amish people. These people do not use new technologies at all. The reason is their religion and believes. It is not expensive to reach people by using media as long as they share the same characteristics.For example, that is not hard to get some information if you speak English, Russian, or French. But if information needs to be translated in the language which is not that popular, companies are not willing to spend money for that. So let’s look at the country called Latvia: small country with a few million people, and with their own language. Recently â€Å"The National Latvian News Agency LETA† posted the article about the findings of scientists’ group called â€Å"MET A-NET† which is made by 60 research centers in 34 countries.Findings showed that Latvian language with other 20 European languages are going to disappear because of the fact that new devices are not supporting these languages(LETA, 2012). That means that if you do not know other, more popular, language you cannot chose the Smartphone you want. Or you have to learn the language, but that takes time, and modern media is not waiting, it is already here. In brief, world is changing so does media. The new media allows to reach people in a very fast way, but there are still groups of people who would not get the message.It is connecting billions of people and the same time forgetting billions of people. After my research I strongly believe that my theses statement in proved, and the new modern media is excluding people with different languages, believes, ages, and financial levels.

Vibratory Rock Tumbler Instructions

Vibratory Rock Tumbler Instructions Vibrating or vibratory rock tumblers, such as those made by Raytech and Tagit, can polish rocks in a fraction of the time required by rotary tumblers. They also result in polished stones that retain the shape of the rough material, as opposed to the rounded shapes obtained by rotary tumbling. On the other hand, vibratory tumblers tend to be a bit more expensive than their rotary counterparts. However, if time is money and you want to retain more of the shape and size of the original material, then a vibratory tumbler may be just what you need. Vibratory Rock Tumbling Materials List A vibratory tumbler.Rocks. You will get better results with a mixed load that includes both small and large rocks.Filler. Plastic pellets are great, but you can use small rocks having the same or lesser hardness as your load.Silicon carbide grit, pre-polish and polish (e.g., tin oxide, cerium oxide, diamond).Soap flakes (not detergent). Ivory soap flakes are recommended. How To Use a Vibratory Rock Tumbler Fill the bowl of the tumbler about 3/4 full with your rock.If you do not have sufficient rock to fill the bowl to the 3/4 level, then add plastic pellets or other filler.Add the required amount of SiC (silicon carbide) grit and water. See the table below to get a sense of how much is needed. If you have the instruction manual that came with the tumbler, start out with those quantities. Keep records, so if you make changes you will know the effect the changes had on the polishing.Place the lid on the tumbler and run the vibrator. Let it run for a day or so and make certain that a slurry is forming. Evaporation will occur, especially if the external temperature is hot, so you may need to add water from time to time to maintain the slurry consistency.When the rock has achieved the desired smoothness and roundness, remove the load and rinse the bowl and the rocks thoroughly with water.Return the rock to the bowl, add a tablespoon of soap flakes, and fill the bowl with water to the top of the rocks. Vibrate the mixture for about half an hour. Rinse the rocks and the bowl. Repeat this step two more times. Return the rocks to the bowl and proceed to the next polishing step with the next grit (see the Table).After the final polish step, perform the washing/rinsing process and allow the stones to dry. Here are some conditions, intended for a 2.5 lb tumbler. You can adjust the quantities for your specific needs. The duration for each step is approximate - check your load and keep records to find the conditions that work best for you. Experiment with different polishing compounds to find the type that works best for your stones.

Helpful Tips for a Perfect Polish Make a balanced load that includes for large and small rocks. For a 2.5 lb bowl, sizes from 1/8 to 1 work well.A proper slurry is needed to get the best polish in the least time. If there is too little water, then the thickness of the mixture will prevent proper movement, thus slowing the polishing action. Too much water results in too thin of a slurry, which will result in a much longer time to achieve a polish. The grit may settle out of the mixture altogether.Never wash grit down the drain! While it doesnt typically present an environmental hazard, theres a good chance it will cause a clog that cant be removed using chemicals.Plastic pellets may be rinsed and reused, but you cannot reuse grit. Are you looking for information on using your tumbler to polish jewelry or metal components? Heres what you need to do.

Civilians in Vietnam Tim O Br essays

Civilians in Vietnam Tim O' Br essays If I Die in a Combat Zone, a chilling depiction of what life was like in the war between the armed forces of the USA and the Vietnamese in the late 60s and early 70s. The way the soldiers lived their lives, minute by minute, not day by day is a chilling insight as to what life was like as a soldier in the way. Was it fair to say that the soldiers of the USA mistreated civilians of the Vietnamese decent or that what they did was just part of being a soldier? Tim O Brien is not only a veteran of the war but is also the author of the novel If I Die in a Combat Zone.
