Sigmund Freud s Theory Of Psychology - 1283 Words

Sigmund Freud (1856-1939), is a pioneer in the field of psychology in various ways. His dedication to his field helped shape the minds of many nineteen-century contemporary schools of thought. Most notably, Freud’s work in psychoanalytic theory, according to Tan (2011) earned him the title of, â€Å"father of psychoanalysis† (p. 322). Moreover, Tan Taykeyesu (2011) report that Freud’s genius is not just in psychoanalysis, but also when we â€Å"think Oedipus complex, infantile sexuality, and repression† (p. 322). His work is purposeful even in today’s therapeutic setting as Edwards Edwards (2010) argue as a â€Å"form of energy source† (p. 221). Still, Freud had his critics that argue his work was simply quackery built upon a heap of a mindaltering drug such as cocaine, and his Freudian psychoanalytic theory unworthy of acclamation (Friedman, 2011, p. 301). The purpose of this paper is not to argue Freud as an imposter, but provide still, another historical perspective of his life and relevant contributions in today’s therapeutic setting, and his school of thought as a useful psychoanalytical theory. Who was Sigmund Freud? According to Tan Taykeyesu (2011), Freud was born May 6, 1856 in Freiberg, Moravia to a wool merchant and an adoring and attentive mother. He had five siblings, but his mother treated Freud exceptionally well, placing his needs above his siblings.

Various methods of formal and informal observation of students during their learning, examinations and quizzes, performance on assignments, projects and presentations are used to gather this information. Lecturers advise that there should be a plan for assessment at programme, course and lesson level, which is often overlooked. As Pratt (1998) stated, to make sure student achievements and grades reflect the learning outcomes established, assessments must be carefully planned, conducted, subject to continuous analysis, evaluation and enhancement. Learning outcomes (knowledge and competence of students), assessment, and teaching are all parts of an integrated whole. Assessment is believed to be essential to the teaching process in delivery and experience of the curriculum.

Deviant Behavior and Drug Abuse Samples †MyAssignmenthelp.com

Question: Discuss about the Deviant Behavior and Drug Abuse. Answer: Tobacco smoking Deviant behavior can be defined as behavior that does not conform to the norms and values of the society. Deviant behavior often elicits a negative response. Deviant behavior can be categorized as voluntary, involuntary, formal and informal (Goode 2015, 23 ). Tobacco smoking has been prevalent practice in the society for thousands of years. It is needless to say that tobacco smoking cause harm to the individual who smokes it as well as to the people who are exposed to the smoke (Goode 2015, 45). Thus it can be considered to be a deviant behavior as it poses a threat to the public health and economy. As assessed by the World Health Organization Smoking tobacco is no longer a social problem on national level but a social problem on the global level. Cigarette smoking also is not illegal in most countries of the world but is not religiously desirable. Thus Cigarette smoking is not as deviant as other illicit drugs. Tobacco smoking can be defined to be culturally patterned. It can be red efined as a social activity (Rubington Weinberg 2016, 15). Cigarette smoking can be said to promote interaction among the people. Illicit Drug abuse Drug abuse can be considered to be a severe form of deviant activity as it poses a serious threat to all the members of a society. Drug abuse exists in multiple levels of the society. Drug abuse generally takes a toll on the communities, social institutions and families (Atkinson 2014, 17). Human beings are prone to become victims of drug abuse and are likely to get addicted to the same. Thus the phenomenon of drug abuse can be considered to be inherently connected to the origin of culture and the society. According to the strain theory of deviance as devised by Robert K Merton it can be said that individuals get addicted to drug abuse due to failure to achieve the social goals by socially acceptable means (Downes, Rock and McLaughlin 2016, 41). According to the theory as devised by Robert it can be said that individuals who get addicted to drugs accept such drug addiction as their fate. Comparison between the two deviant activities Thus after analyzing the deviant activities of smoking as well as illicit drug abuse, it can be stated that smoking is perceived to be less harmful to the society than illicit drug abuse. Smoking however is not desirable, is socially acceptable in most countries (Murph 2015, 12). Cigarette smoking has also been perceived to promote or encourage social interaction between people. However, the harmful effects of smoking are not to be undermined. Smoking although not considered to be serious deviant activity, is the cause of the most number of deaths all over the world. Illicit drug abuse can be considered to be a far more serious form of a deviant activity. The consequences of drug abuse are detrimental to the society (Hirschi 2018, 12). Illicit drug abuse is strictly forbidden and illegal in most countries of the world. Illicit drug abuse adversely affects the society as teenagers can get easily victims of drug addiction. Illicit drug abuse often promotes degenerate behavior among ind ividuals and also is closely associated with antisocial activity.

The United States themselves are essentially the greatest poem. Here is not merely a nation, but a teeming nation of nations (741).

A LAN is a way of connecting multiple computers together in an arrangement which allows the computers to communicate freely with one another. With the dawn of multiplayer computer games, LANs have become increasingly popular as a way to play head-to-head with others without suffering with the effect known as "lag".

When someone has lag they have a high latency, or a greater amount of time for one computer to send a message to another computer (Xavier). Exactly when LAN parties started, no one knows exactly.

Bilingual education benefits everyone Essay Example | Topics and Well Written Essays - 500 words

Bilingual education benefits everyone - Essay Example The political shifts of the 20th century greatly curtailed bilingual efforts and recent political views against it have raised the issue once again. Advocates of an English only system have pointed to the need for national identity, but this approach has led to the sink or swim attitude of educating our students and the effect on the student and society can be detrimental and the cost is certainly high. Students need to progress into our language as well as our society. With a bilingual program, students are taught the desired English, yet have the chance to explore other subjects in their native tongue. This keeps the student on pace and their additional knowledge aids in the learning of English. If a student gets left behind in the sciences, math, or current events due to a lack of English skills, that student will not develop the necessary skills and requirements at an important point in their education. Students who are not struggling with the language barrier are more interested and involved with the material and subsequently perform better. Bilingual education is not a replacement for English, it is a valuable addition to the curriculum. Bilingual education not only provides the only workable approach to teaching non-English speaking students, it also has advantages.

Low-risk 1 - Essay Example (Dr. Andrew Wood) Puritans were people were very impressive and were greatly determined to make an impact on the new generation. The puritans were Englishmen who emerged from the Elizabethan era. They were hopeful and cheerful people who had a â€Å"Can-Do† attitude and were willing to accept any challenge with great courage. The puritans whenever they used to have a problem with other people or some influential powers they would sort out the matter through negotiations and in accordance with the teachings of Christianity. The main and only purpose of the Puritans was just prayer and nothing else. To them the solution to every problem was in the teachings of God. For them their faith did not just meant going to Sunday mass but it was more than that, they were close to God in almost every way of their life. Due to their Biblical Christianity they suffered a lot as they were treated very badly by the established Church and the English Crown. In short the Puritans were people who were cheerful ha ving great faith in God which they passed it to their children no matter what the consequences were. (Gavin Finley) "Noe man is made more honorable than another or more wealthy &c., out of any particular and singular respect to himself, but for the glory of his creator and the common good of the creature, man" (p. 1).

Finally, a conclusion will be provided to summarise all research findings and mentioned business management issues / problems. Before critically analysing the functions and management issues in a global business to identify ways to reduce risk and improve organisational effectiveness, I first would like to throw light over what we mean by efficiency and effectiveness. Organisational efficiency refers to the capability of a business enterprise to produce maximum output with the help of same available sources. In other words, it could be defined as an ability to produce same level of output with fewer sources. The world has become a global village after the contemporary developments and advancements in information technology and communication networks. These recent advancements and improvements in media networks and advertising have greatly affected the attitudes, beliefs, behaviours, lifestyles and perceptions. At the same time, this has also created many business opportunities for enterprises. In fact, many businesses have gone global and have become transnational, multinational or supranational corporations with operations all across the world. Companies today are expanding their operations all across the globe to target a large group of potential customers who are heavily exposed to media, and who now have relatively similar lifestyles (inclination towards a white collar job, brands, facilities, luxuries etc). On the other hand, customers have also become very demanding, since they seek value and are inclined towards new and innovative products. In short, it could be said that busines ses have to deal with a large diverse group of customers who have both willingness and ability towards different innovative and existing products. Businesses usually have many different international market entry

Comparing Eastern and Western Management Styles

Comparing Eastern and Western Management Styles Nowadays, organizations exist in the competitive business environment where theres rapid development which lead to high failure rate and difficult to stand up among the strong competitive environment. Turbulent business environment caused lots of organizations to face bankruptcy; however, there are still many successful organizations which have great success through their hard work. For those successful organizations, the main objectives are to maximum their competitive advantage and increase their market shares in the market place. However, such aim cannot be accomplish without the combination of instrumental and conceptual knowledge in their management practices. In fact, every successful organization needs competent people who have the all- around knowledge of leadership. Every business has a person to lead the organization to achieve success. The ability of this person to lead is essential to sustain the performance and growth of any businesses. Such person is sometimes seen as a charismatic leader, or even a competent manager can help to growth a business by manage the employees and operation effectively. In fact, the person who was seen as a leader of the organization is mostly the CEO of that organization, the decision and every single action that the CEO take will have massive impact on every single employee within the organization. The ability of a CEO to become a leader is essential in today competitive environment since CEO which has the ability to lead and create follower can create a vision for the organization and every people in that organization will be unite to achieve that vision. Mullins (2005) and Huczynski Buchanan (2007) also pointed out the important of leadership existing in the organizations. Hence, this essay will focus on the instrumental and conceptual knowledge of leadership by comparing two leaders from different culture and situation. 1.0 Introduction to Leadership Leaders are perceived as the heart of a business which inspire the whole organization and create vision for that particular business. Leadership is no longer a new word in the organization, but it is still a controversial word that many scholars concern with, because of the role we assume it plays in the organization is crucial. And there is always lack of the competent leadership in the society. In that case, lots of authors and scholars define the term of leadership through their understanding. In 1950, through long times study, Stogdill defined the term of leadership as the process of influencing the activities of an organized group in its efforts towards goal- setting and goal achievement (cited in Huczynski Buchanan, 2007: p. 716). According to Robbins Decenzo (2005: p. 240), leader may be defined as persons with managerial and personal power who can influence others to perform actions beyond those that could be dictated by those persons formal (position) authority alone. Moreover, as leader in the recent year, their responsibility is coordinating the others and followers at most of the time. From goal focus to human behaviour focus, or from autocratic leaders to democratic leaders, they all demonstrated that leadership is more and more important for any organizations. Leaders versus Managers However, there are distinguishing between leaders and managers which we should realize before analysing the leadership within the organization. Some argue that manager is not a leader, but the roles of a manager require them to become a leader (Huczynski Buchanan, 2007). As Robbins Decenzo (2005: p. 244) suggest not all leaders are managers, nor are all managers leaders. There are differences between a manager and a leader, manager manage but a leader lead. Robbins Decenzo (2005: p. 239) defined manager as persons whose influence on others is limited to the appointed managerial authority of their positions to reward and punish. Manager manage the rules, follow the procedures and manage everything according to the system and structure establish by the company, they manage the people by the power and authority they have, people are managed not because of the manager, it is because the authority and power that the manager have. However, some argue that leader can create follower and make people to believe without any power or authority, people are willing to follow the leader on their own behalf and will (Huczynski Buchanan, 2007). Thus, there are no clear line that separate a manager and a leader, a CEO can have the characteristic of both which make them more competences to manage and lead the company to a greater success. It is undeniable that in today competitive environment, both leading and managing role are critical success factor for a CEO to have in order to achieve greater achievement (Kyle, 2004; Kotter, 2001). As De Wit Meyer (2004: p. 497) argue, Every leader must perform some managerial functions, even though every manager cannot take a leadership role. Wit Meyer (2010) argues that: the leader controls the allocation of the attention focus of the participants in the organization in any organization where managers dominate, structured rules tend to influence the allocation of attention, but the leader will try to capture the attention focus of the participants so that their attention is allocated to the areas that the leader considers important. Leaders to Discuss and Compare This paper will discover two successful leaders Jeff Bezos from the west and Akio Toyoda from the east by comparing their leadership style and other aspects related to leadership in order to discover the differences of leadership in different culture and background. Jeff Bezos from the West Jeff Bezos is the founder, president, chief executive officer and chairman of the board of Amazon.com (New York Daily News, 2008). He founded Amazon.com in 1994, and launched in 1995. As a founder and CEO of Amazon.com, Jeff Bezos is a pioneer in e-commerce (Spiro, 2009). As shown in Fair (2002): At the end of 1999, Amazon had raked in over a billion dollars in sales à ¢Ã¢â€š ¬Ã‚ ¦ in 2001, Amazon reported a fiscal loss of $1.4 billion, and had laid off over 200 workers in the last year à ¢Ã¢â€š ¬Ã‚ ¦ Instead of giving up, Bezos had an idea: recruit other companies to sell their products online through Amazon as well. The idea worked. Companies such as Target, Toys R Us, Old Navy, and many others have agreed to sell their items through Amazon. Although Amazon is not directly responsible for inventory through these companies, they do get part of the sales, creating a profit for all involved. Since the inception of the idea, Amazon is now back on its feet and remains one of the most popular online vendors in the world today. Akio Toyoda from the East According to Los Angeles Times, 2009: Toyota tapped Akio Toyoda, grandson of the Japanese automakers founder, as president of Toyota à ¢Ã¢â€š ¬Ã‚ ¦ The U.S.-educated Toyoda, 52, is the first founding family member to take the helm at Japans No. 1 automaker in 14 years. He promised a reaffirmation of the companys core principles, such as valuing ideas from the ranks a management approach called kaizen, [also known as Toyota Production System] that has made Toyotas production methods famous in industry circles around the world. 2.0 Comparison of Leadership Style and Culture 2.1 Participative Leadership Style and Charismatic Theory Jeff Bezos is more like a charismatic leader that practiced participative leadership style. Although he faced some obstacle in the early years, he managed to overcome the entire problem and bring Amazon to become one of the most innovative companies in the e-commerce industry. He launched Amazon.com and being persistent in persuading his aspiration, one of the characteristic of leader as describe by Mullins (2005). Jeff Bezos has the criteria as a charismatic leader as he has the ability to create a vision for the future and make everyone within Amazon believe in his visions that make him a charismatic leader. A vision should create enthusiasm, bringing energy and commitment to the organization (Robbins Decenzo, 2005: p. 246), while Ingbretsen (n. d.) argues that a charismatic leader has the ability to articulate a vision that touches an emotional chord with an audience. Jeff Bezos manages to lead people by making them believe that his innovative idea of online bookstore will be a s uccess. He had prove his vision are achievable and people believe in him since he lead everyone in the company to work hard and achieve the goal and objective to become the innovative player within the e-commerce industry, and people believe in him since he managed to turn the situation of Amazon around. As Robbins Decenzo (2005: p. 247) suggest, Charisma leadership appears to be most appropriate when the followers task has an ideological component or when the environment involves a high degree of stress and uncertainty. However, based on the other perspective that goes against charismatic theory, Raelin (2003) suggest that follower will follow the charismatic leader is just because the publicity make the leader look so powerful and great. The fancy packaging with the help from media had made the charismatic leader look like a legend, a myth that everyone believe is true. Levesque McNeil (2003, p. 215) strongly argue that as followers interact, they begin to define a social reality of leadership representing special mythical qualities endowed only by very special people. Raelin believes that followers are predisposed to look for a cause and a leader for whom they can become true believers (2003, p. 66). The critics for charismatic leader are that without massive publicity, there will be no charismatic leader; people will not recognize that leader at all. If Jeff Bezos is not good at making himself high profile by attending conferences, posting his own comment or opinions on the web, attending public events, accept a lot of interview and so on which make him highly expose to the media and make publicity for himself and the company as well, there will be no quoted as a charismatic leader for him. He was being quoted as a charismatic leader as people know what he done through the media and all the fancy publicity which make him look as great as a hero. There are many leaders around the world, even if we do not know their names or what great things that they have done, it didnt make them less an effective or great leader. Charismatic is not the only recognition for a great leader, people recognize the leader that they respect within their heart, even without the media spreading that lea der legend, people will still respect that leader, even he or she is not a charismatic leader. Indeed, some of the most significant CEO in the history of the visionary companies did not have the personality traits of the archetypal high-profile, charismatic leader (Forster, 2005, p. 30). 2.2 Autocratic and Collaborative Leadership Style On the other hand, Akio Toyoda practiced the autocratic leadership style and until now, the belief of autocratic leadership style still remain within the organization and most managerial level personnel practiced the same autocratic leadership style to manage their people. The main reason autocratic is effective at Toyota mostly based on the power-cultural that Japan always have. Akio Toyoda as president of Toyota is reaffirming its commitment to collaborative culture and methods (Rosen, 2009). Although being autocratic, Akio Toyoda practiced Genchi genbutsu or see it for yourself fits squarely into collaborative culture and methods of Toyota (Liker, 2004). As leaders, Akio Toyoda suggests that manager needed to hold themselves accountable for all their decisions, which they required their people to execute very quickly. Collaborative leadership and autocratic style of Akio Toyoda doesnt make him stay away from their unique kaizen production method, but to collaborate more with the implementation of lean production plant which was known as the Toyota Production System (Liker, 2004). Toyota Production System distinguished from its competitors and hard to duplicate since it is underpinned by just-in-time delivery (JIT); product quality; employee flexibility and the elimination of waste. This unique lean production system was buttressed by principle such as teamwork, continuous improvement, quality circles and employee development. 2.3 Traits Theory Although both leaders practiced different leadership style, they have their own personality traits that made them a great leader. First of all, based on the instrumental knowledge, the traits theory also call traits- spotting is argued even in recent years, for the reason of that leader is nature born or make. Although, there are thousands of successful leaders existing in the world, all of them have their own traits which can be summarize as six leadership traits including ambition and energy, desire to lead, honesty and integrity, self- confidence, intelligence and job- relevant knowledge. Hence, instrumental knowledge indicated that the traits are the distinguishing personal characteristics of a leader through six leadership traits (Robbins Decenzo, 2005: p. 256). However, not every leader has all of the personal traits instead of maybe some of them. And lots of examples tell us that leader with different traits also can obtain successful in every area. For instance, Jeff Bezos a nd Akio Toyoda have total different characteristics and personal traits, but both of them acquired big successful in the business world. However, in contrast with the instrumental knowledge, the conceptual knowledge holds that it is difficult to identify whether any people is naturally born with trait, or they might just gain those ability through their life experience and learn from it. Besides, different countries which have different culture will need leader with different characteristic. Thus, every leader which is required in different country will need to have different trait. For example, people from the Western countries and people from the Eastern country will have different culture or ways of doing things (Hofstede, n. d.). Thus, different leadership style need to be implement in different countries, if that particular countries are afraid of uncertainty and have a high level of avoidance for confusion, such as China, Japan and others, the Autocratic style might be more appropriate. Therefore, there is no one universally accepted set of traits for all leaders. Every single individual are different, their abi lity and skills, knowledge and experience will be different as well and they will be accepted in the mind of different people which appreciate their traits. 2.4 Behavioural Theory The most popular behavior style theory should be Blake and Moutons Grid which is based on the idea that different in leadership approach are a function of concern for people and concern for production emerged during the 1960s (Doyle Smith, 2001). According to behavioral theory, it is easy to find out which style the leaders are belonging to by identifying the behavior. For example, leadership styles are another important aspect from the management process where different country will have different management style. Huczynski Buchanan (2007) suggest that leader cannot use the same leadership style in their various locations around the world due to the cultural and behavior differences. Japanese leadership style differs from those in the U.S and the most common is that Japanese (Akio Toyoda) and U.S (Jeff Bezos) leader have a basically different philosophy of managing people. For example, Jeff Bezos is heavily individual-orientated and will praised individual with great performance in front of everyone. However, a Japanese saying is, the nail that sticks out gets hammered down which mean that no individual should stand out from the group. Giving out individual reward system in Japan could embarrass a Japanese worker and is not accepted at Japan. Western motivation models are culturally individualistic, applying them to a collectivistic culture is probably inappropriate. As Fujisawa, co-founder of Honda Motor Company stated, Japanese and American management is 95% the same and differs in all important aspects (Keeley, 2001, p. 18; Erez Gati, 2004). U.S leadership style is not appropriate at Japan where the Japanese employees are unable to accept or tolerate participative and individual orientated leadership style. Mintzberg Westly (2001) suggest that Japanese worker dislike emphasize on individual performance and more toward group-orientation, and will felt appreciate if their leader can pay some attention to them at work and also concern a little bit about their personal life, like what Akio Toyoda did as a leader at Toyota. Akio Toyoda was more willing to allow poor performance to continue for a time so that those who were involved would learn from their mistake and to harvest loyalty among employees. The example above clearly showed that there are clearly different ways to work in different culture and it is important for leader to understand such differences and manage the employees based on their own culture. Huczynski Buchanan (2007) argues that leadership styles vary from company to company. There are many different styles of leadership that can bring success to an organization but organization has to make sure that their leadership style is right for the business. Which leadership styles to practice depend on many factors, but the most determine factors that has the biggest influence on management style will definitely be culture and behavior. 2.5 Contingency Theory and Hofstedes Five Cultural Dimensions Fiedler and his associates bring out the contingency theory which combines leadership style and situation during 1960s. In Fielders model, the good performance of the group depends on the interaction of the leadership style and the favorable situation, and a good leadership must be flexible and adaptable in order to appropriate different situation within the organization no matter how hard or soft situation (Huczynski Buchanan, 2007). Thus, there is no single style of leadership which can match to all situations; even the most effective leadership behavior should depend on the situational factors. Hofstede (n. d.) commented that: Western countries have characteristics of high individualism, medium uncertainty avoidance, high masculinity, low to medium power distance, and low long-term orientation. [Thus, based on the situation, it is best for Jeff Bezos to practiced participative leadership style in USA. On the other hand, eastern countries such as Japan] was found to have characteristics of low individualism, high uncertainty avoidance, high masculinity, high power distance, and high long-term orientation Hence, it is more appropriate for Akio Toyoda to practiced autocratic leadership style to suit the cultural and situation at Japan. In order to compare the different culture of USA and Japan, Hofstedes Cultural Dimensions of USA and Japan will be as the following (Hofstede, n. d.): Source: Geert Hofstede, Cultural Dimensions, www.geert-hofstede.com 3.0 Conclusion In conclusion, it is undeniable that Jeff Bezos is a great CEO which made Amazon a famous and innovative online company globally. However, it is too narrow to believe that charismatic leader is everything since Akio Toyoda is still a great leader without being a charismatic leader. Jeff Bezos is a charismatic leader, it might be his style to be one, but charismatic leader style is not suitable for everyone or in different culture, background and country, it might not be essential. Therefore, there is no one universal accepted leadership style that is the most effective one. Great leader are not only charismatic leader, anyone who was seen as a great leader, no matter what his leadership style was, is nothing less an effective leader if they were not quoted as one. Thus, culture differences play a significant role whereby leaders must consistently aware of the cultural change and react to the situation in order to lead their staff with the most appropriate type of leadership. Without acknowledging to the aforesaid, one will never be a good leader.

Epilepsy And The Blood Type Diet :: Biology Essays Research Papers

Epilepsy And The Blood Type Diet Are people with certain blood types more susceptible to chronic seizures than others? Can a simple diet reverse this medical condition? And why didn't anybody think of this before? There's a myriad of fad diets out these days: Atkins, the fruit juice diet, Russian Air Force diet, and the Zone to name a few. However, the most recent craze is, "The Blood Type Diet", based on the book, Eat Right 4 Your Type by Doctor Peter D'Adamo. The diet focuses on an individual's genetic makeup (blood type) in determining which foods are best digested. D'Adamo heads up the Institute for Human Individuality (IfHi), which "seeks to foster research in the expanding area of human nutrigenomics. The science of nutrigenomics (naturopathic medicine) seeks to provide a molecular understanding for how common dietary chemicals affect health by altering the expression or structure of an individual's genetic makeup" (1). On the website, the "five basic tenets of nutrigenomics" are listed as: 1. Improper diets are risk factors for disease. 2. Dietary chemicals alter gene expression and/or change genome structure. 3. The degree to which diet influences the balance between healthy and disease states may depend on an individual's genetic makeup. 4. Some diet-regulated genes (and their normal, common variants) are likely to play a role in the onset, incidence, progression, and/or severity of chronic diseases. 5. "Intelligent nutrition" - that is, diets based upon genetics, nutritional requirements and status - prevents and mitigates chronic diseases. (1). The Blood Type Diet is founded upon the microscopic observation of how ABO types break down different foods, suggesting that one person's nourishment may be another's poison. The book examines the demographic distributions of different blood types, and proposes that "the variations, strengths and weaknesses of each blood group can be seen as part of humanity's continual process of acclimating to different environmental challenges" (2). D'Adamo asserts that blood groups "evolved as migratory mutations," with type O being the most "ancient" of the ABO group, and housing the largest population (40-45%), second to type A (35-40%), dwindling in B (4-11%), with the rarest being AB (0-2%). People with type O blood (hunter-gatherers) are encouraged to be carnivores, while type A's can survive solely as vegetarians. Explaining the origin and spread of blood type B, D'Adamo states, "Two basic blood group B population patterns emerged out of the Neolithic revolution in Asia: an agrarian, relati vely sedentary population located in the south and east, and the wandering nomadic societies of the north and west" (2).

Ontela Picdeck Essay

Ontela PicDeck creative approach to have cellular customers have the ability to automatically have pictures and videos directly sent to their computer. This reduces time needed and simplifying the strenuous act of doing it manually. The U. S mobile phone service industry earned 150 billion dollars in 2007 and growing. This technology has potential of playing a role in that with critiquing the marketing strategy they have approached the market with. It is essential for a better marketing strategy for Ontela to show customers so they can better understand the benefits and how to efficiently utilize it. The qualitative research segments best defined the customer expectations. Sarah, the parent, loved the fact the pictures â€Å"just appear â€Å"on the computer automatically. Steve, the young professional, looked to not always have to lug around the digital camera. Instead have a phone that can take care of both jobs. Regina, the teen, expectation exceeded both Steve and Sarah, but still within the abilities of PicDeck. Regina wanted to manage her pictures from her phone and monitor the pictures for her social networking sites. Herzberg’s 2-factor theory can be used in this instance. Using this theory to understand and distinguishing what motivates the purchase while staying â€Å"relevant†. In other words you must keep up with the recent trends like the social networking wave. These three segments all produce various expectations but all acknowledged the expectations of a simplified and quicker method to transferring pictures. These segments age groups and lifestyles greatly vary so the solution to market them must be more specified to that target group. The improvement of creating a more knowledgeable customer base will require a critiqued advertising campaign. In the case of Regina, advertising within the social networking programs like Facebook and MySpace. This advertising will catch the attention of these teen and inform them of the product. Specifically push the simplicity, timeliness, and how the pictures are still stored even when your cellular device is lost. For the younger generation and phones being a huge commodity, phones are constantly being stolen and lost. If interpreted right, then the teen will approach their parents to have their plan changed to include PicDeck. Then the parent will be informed and furthering the utterfly effect of a strict advertising scheme to the teenage target customers. This is how Sarah would be notified. Social is a major influence in customer behavior through family, friends, and reference groups. All play as contributors to trusting a buy of a product. Continuously for people who aren’t very tech savvy like Sarah and Steve; they do though always have an email and usually check it frequentl y. So a mass email to the entire customer base informing them of the new product. Steve would be influenced more by the occupation. Besides using this program for personal use, Steve would use this for his real estate job. To be successful in a job market like Steve’s you must influence your work with newer technology so you may keep up with competitors. â€Å"With PicDeck, work assignments are accomplished more efficiently and simply†, statements like this boost the products equity and what customers like Steve would want to hear. For a product to blossom you must target the younger generation first. With constant technology improvements it’s hard for the older generation to keep up. The younger generation is constantly working with the new technologies so you inform the younger generation and it will spread to older generations. Ontela has created an inferior product and now need to raise awareness of the tech advances this product has influenced. The magazine Telephony stated PicDeck to be â€Å"helping the bridge the gap between phone and PC†. Continuous advertising is needed in magazines for the working class people to involve this program into their workplace. For instance putting an ad in the magazine SkyMall. The magazine you see on every flight you’re on. This can target a business class customer base because the individuals who travel most are individuals travelling on business. And this is the only reading material on the plane.

Free Essays on Social Capital

Introduction Social capital has commonly been studied in recent years from the perspective of sociology and political science. Through the various different works of Robert Putnam, Francis Fukuyama, and James Coleman, as well as others, the complexity of social capital has been broken down to people’s relationships and the values which they hold with each other. Social capital has been regarded as a useful element in democratic governance (Putnam) and economic stability in countries (Fukuyama). Trust has become a main element in the development of social capital. Civic engagement, social networking, and participation in public organizations help boost social capital, but these trends are on the decline in America. Many theorists believe this is the reason for our lack of trust in the government. If the people do not place trust in each other, than how can they trust the people which they elect into office. This is the very concept in which I developed my hypothesis: In comparing individuals, people who place more trust in others are more likely to trust their government than are people who place less trust in each other. The independent variable for this experiment will be the level of trust placed in others by people and the dependent variable will be the trust placed in the government by the people. The relationship between the two variables should have a positive correlation if the hypothesis is correct. There have been many studies conducted by both sociologists and political scientists concerning these two variables and its effects on social capital.

marx and tocqueville essays

marx and tocqueville essays To understand what Marx and deTocquiville ;two of the great social thinkers of all time, believed, you have to understand what was going on at the time. They were living in the peak of the Industrial Revolution. The cities that housed this revolution were overflowing with factories and people. People who were once country folk decided to come out to the cities in search for a better life. These working class people were also known as proletariats. Another aspect was what were these people thinking? They had there minds set on the right thing, a better life, but what made them think they would live a fair life? Liberalism was The bourgeoisie, or higher class believed in this ideology, and it rubbed off on the working class. Liberals believed in a constitutional government, equality of opportunity, and laissez faire economics. They believed in self interest, freedom, and privacy. So why then were the working class people poorer than when they were in the country, lived in slums and shacks, and worked terrible hard hours? This is where Karl Marx comes in. Marx saw that the proletariats had no rights. He thought that they lacked political power and government protection. He felt that it wasnt fair for the upper class to control the means of production and business in general, when the working class was doing all the hard work. He said that the working class was the class that had to bear all the burdens of society without enjoying its advantages. Materialism was also a factor in this class struggle. It proved that the class struggle could not be evaded. After studying the social classes in America, he came to believe that classes were not bad at all. He was impressed by the general equality of conditions among the people. He thought that the democracy that was in America at ...

Presidential Paper Research Example | Topics and Well Written Essays - 1250 words

Presidential - Research Paper Example He was instilled with a sense of charity and the importance of giving to others (Morris, 1979). Throughout his childhood, he struggled with many illnesses that he had to overcome (Miller, 1994). That spirit of conquering whatever he was faced with would stick with him throughout his life, making him an exceptional leader and a person of great accomplishment. Theodore Roosevelt would have been known for his many accomplishments, even if he hadn’t become President. In terms of government office, Mr. Roosevelt held many public offices prior to being elected President. He was an assemblyman for the state of New York and governor of New York as well. He was also the Police Commissioner of New York City, a U.S. Civil Service Commissioner, a sheriff in the Dakota Territory, Assistant Secretary of the Navy and Colonel of the Rough Riders and Vice President of the United States (Roosevelt, 2012). This was all accomplished before he became President when he was 42. During his career, he also ran for Mayor of New York, but was not elected. Teddy Roosevelt was the nation’s first environmental President. Those before him did not have any type of effort towards the environment. President Roosevelt protected 230 million acres of land while he was in office (Roosevelt, 2012). This 230 million acres included 150 National Forests, 51 bird reservations, 5 National Parks, 18 National Monuments and four game preserves (Roosevelt, 2012). The fact that in the early 1900’s he thought to preserve land is impressive considering that those dedicated lands still exist today. He also made land preservation and conservation a topic for consideration which had not previously been of interest to the people and to the government. Now, in 2012, political campaigns always include opinions about the environment and conservation. It is

The Joint Intelligence Committee model Essay Example | Topics and Well Written Essays - 3500 words

The Joint Intelligence Committee model - Essay Example The most sparkling thing with the Joint Intelligence Committee is that the committee has managed to maneuver all the critics and scandals that are likely to occur in such a remarkable organization and of high value. According to Aldrich (1992, pp.112) Joint Intelligence Committee is a success that the British government has enjoyed for a long period of time. With time, the Joint Intelligence Committee has attained the label of the government’s flagship. Other researchers have traced the reports of the Britain’s central intelligence in the quest for looking for information that answers all questions that pertain to the Joint Intelligence Committee. In fact, other analysts have made a great attempt to trace the works of the Joint Intelligence Committee’s former chairman, all in an endeavor to understand their records and thoughts on the Committee. This essay will undertake a detailed research on the Joint Intelligence Committee by analyzing the works of various analysts who have undertaken a great percentage of their time to conduct a detailed research on the project. For an understanding of the project, it is important to evaluate the parallel systems in other countries, to comprehend the effectiveness of the Committee. In as much the Joint Intelligence Committee has recorded massive failures whilst in its operations, notable- the onset and closing stages of the cold war- it is important that, both sides of the operations are weighed to avoid bias wile taking the final conclusion. For instance, if the Joint Intelligence Committee is judged on the basis that, it was able to predict the attack of the Soviet bomb to the Britons by 1954, but occurred by 1949, would be taking a harsh stand on the ability of the Joint Intelligence Committee to create a situation whereby they are able to come up with workable solutions on the validi ty and reliability of the committee. 2.0. Brief history on the Joint Intelligence Committee (JIC) The Joint Intelligence Committee (JIC) has had the longest history prior to its establishment. Grant (2009, pp.178) indicates that, the Joint Intelligence Committee (JIC) traces its roots to the early 1940s. During this period, the Committee played the role of a synchronizing the founder chiefs of the organizations in order to, have a stable base of operation. The major proponents of this Committee included, the directors and delegates of persons with intelligence form various governments’ settings like, UKs army, navy, Economic warfare as well as, the coordinator of information. The growth and development of the Joint Intelligence Committee (JIC) was hastened by the 1947 National Security Amendment that made room for refurbishing the outmoded approach. It is after 1947, that the Committee witnessed hastened growth with the incorporation of persons with ideas on the advancing int elligence in all forms of the Committees’ systems and departments. For instance, it is at this time that, the Committee aimed at creating a situation whereby military intelligence is combined. However, the Committee did not manage to create a unified military intelligence attributes from Phythian’s (2005, pp.654) argument that, no evidence has been documented on the Committees’ statistics that national intelligence estimations are vivid. In response, research conducted by Aldrich (1992, pp.98), indicates that, the committee had to conduct a series of meetings in an attempt to alleviate the hitches that were present in the system as well as, allocating specific roles to various members of the committee.

Research Proposal - Essay Example For instance, IBM is availing opportunities to enable managers to obtain necessary skills as well as an orientation for coping with the different culture (Okoro, 2013). According to Kawar (2012), cross-cultural communication can be defined as the study of how people of different cultural background can communicate with each in relation to same or different topics. Kawar (2012) also, addresses that today cross-cultural communication is essential for international business due to the development of global business, internet and technology (Kawar, 2012). Okoro (2013), also addresses that cross cultural communication is essential in international business for conducting the different needs of IBM effectively with the use of advanced technologies and internet. Through the cross-cultural communication, managers at IBM Limited can communicate with the people belonging from different cultures. In addition, it can effectively gain insight into the different operations that needs to be undertaken for conducting successful international business (Okoro, 2013). According to Guang & Trotter (2012), for the enhancement of successful international business, there should be collaboration between various departments at Coal India Limited and the cross-cultural communication. However, Guang & Trotter (2012), in his article does not cover what types of problem a manager can face in the process of communicating with people of foreign countries while travelling abroad for the first time. Therefore, there should be further research related to the sele cted topic to mitigate the number of gaps. These gaps should be identified to develop potential solutions through which the problem can be solved (Guang & Trotter, 2012). On the other hand, Matthews & Thakkar (2012) comments, there should be effective communication among the managers and juniors employees to reduce the organizational problem and chances of grapevine in communication could be reduced largely.

Social media negative impact on teenagers Essay Example for Free

Social media negative impact on teenagers Essay Many types of social media display a ‘bad boy’ image which consists of addiction to substance abuse (drugs and alcohol), violence, emphasis on luxurious material possessions and lack of moral values. It is this ‘bad boy’ image that severely impacts the minds of teenagers. It is very common to find a video of a celebrity portraying a character that is addicted to substance abuse. For instance, Youtube is filled with plenty of music videos, movies and pictures that display celebrities with numerous addictions to substance abuse. Examples of such celebrities include, Nicolas Cage (alcohol addict) in the movie Leaving Las Vegas and Leonardo DiCaprio (drug addict) in the movie The Basketball Diaries. When a celebrity plays a fictional role of an addict, many teenagers pick up the addiction. Teenagers tend to think that such types of addictions are ‘cool’ as their icons engage in such addictions. In addition, social media portray a lot of violence that amuse teenagers. For instance, cp24.com shows videos and pictures of gangsters and thieves shedding blood of innocent people. In such situations, culprits are often seen settling problems through violence rather than through peace. Teenagers pick up on this depiction of brutality and think that it is better to solve a conflict through violence in order to gain a popular image in society. Also, social media is actively engaged in promoting exquisite materialistic goods. For instance, Facebook displays many pictures of celebrities endorsing expensive products. Examples of such endorsements include Michael Schumacher (Ferrari, Lamborghini) and Jessica Simpson (Gucci, Prada). Teenagers that look up to their icons come to the conclusion that in order to be popular one must acquire such luxurious goods. Moreover, social media places a great emphasis on acting immorally. For example, etonline.com shows real life situations of celebrities lying, stealing, and taking part in scandalous affairs. Teenagers are often taken into believing that such irresponsible acts are normal and expected to be followed. Thus, it is fairly evident that social media plays a vital role in exerting a strong negative influence on teenagers.

The Liquid Ring Pump

The Liquid Ring Pump The performance of a two-stage liquid ring pump with water as the sealant liquid was investigated under stand-alone conditions. The parameters varied in this experiment were the cooling water flowrate and inlet air volumetric flowrate which affects the sealant water temperature and pumping speed respectively. Pressure and temperature readings were taken to calculate the compression work and efficiency across the liquid ring pump. It was found that efficiency improved at higher cooling water flowrates and lower sealant water flowrates. As the inlet air mass flowrate was increased, it was also observed that the suction pressure, pumping speed, and compression work increased. These trends compare well to similar investigations done in literature. Assumptions made to describe the performance of the LRP were isothermal compression, ideal gas, dry air as inlet gas, and no loss of energy to the surroundings. Energy balance done across the liquid ring pump showed an agreement to literature ( 1) that isothermal compression was found to be more thermodynamically efficient compared to an adiabatic process. Further work can be done by investigating he pumps performance using different sealant liquids, inlet gas moisture content, and in conjunction with reflux/reboiler and reflux/condenser. Problem Statement Morton Labs Inc. has commissioned an independent evaluation of their liquid ring pump rig. They would like a report on the performance of the pump under a wide set of conditions and its suitability to operate with the Reboiler/Condenser and Reflux/Condenser rigs in their plant. Group A3 was required to plan and carry out experiments that can provide data for such evaluation. The evaluation should include mass and energy balance calculations, performance data and an analysis and description of the behaviour of the pump as well as any suitable model. You will have access to their facility and will be shown how to operate the equipment. Introduction The concept of vacuum has long been the subject of interest of philosophers since the times of the Ancient Greeks due to its profound uniqueness and was recreated by physical means with the creation of what can now be described as the first vacuum pump by Otto von Guericke in 1650. (2) Vacuum pumps have been steadily improved and advanced since then but it was not until huge advances in the late 19th and early 20th century paved the path to what would become a vital organ in several industries such as chemical, pharmaceutical and food industries. (2) In a typical paper mill for example, vacuum is mainly used to assist the removal of water in wire drainage and pressing sections in addition to several other purposes. (3) For such an industry, liquid ring vacuum pumps are utilized in order to create the vacuum needed for the mentioned processes. (4) In order to produce vacuums in the most efficient manner, the behaviour and performance of liquid ring pumps needs to be studied in order to reduce costs of operation and reduce energy consumption. Several investigations such as those by Powle and Kar (4) and Chilvers and Love (5) on measuring the behaviour of liquid ring pumps have been conducted due to the importance of determining performance. The objective of this set of experiments is to determine the performance of the 2 phase Hicks Hargreaves SLR type liquid ring pump the located on the B-floor of the Morton Laboratory. Performance can be described by varying flow conditions of the sealant water and cooling water supplied to the liquid ring pump and taking pressure and temperature measurements accordingly. This report will start by describing the operation of liquid ring pumps and the technical theory used to describe their performance, followed by the experimental plan and the methodology. The data collected will then be analysed in order to create trends describing the compression work and the isothermal efficiency of the pump in question. The report will be concluded by suggesting possible areas to be further studied in addition to answering the objective of the experiment. Background Liquid Ring Pump (LRP) The liquid ring pump operates as a vacuum pump using liquid as a compressing agent. It consists of a metal cylindrical body containing an impeller and blades set off centre with respect to the central line of the pump. The liquid ring pump must then be partially filled with a liquid which will act as the sealant and results in forming a vacuum. This is illustrated in figure 1A. The sealant liquid can be either water, oil or a solvent, depending on the application of the pump. When the impeller starts to rotate it throws the liquid in the pump against the walls by centrifugal force. This will cause the impeller blades closest to the wall to be completely submerged in the liquid sealant and the impeller blades furthest away from the wall create a void space with the liquid ring. This is because the impeller is set off centre. This void space sealed off by the liquid and the impeller can be seen by looking at figure 1B. As the impeller rotates anti-clockwise from the top to the bottom, the area of void between the impeller and liquid sealant expands. This creates a suction force which draws gaseous fluid into the pump inlet, as the impeller carries on rotating anti-clockwise from the bottom to the top the liquid is forced closer to the impeller compressing the void space and creating a compression force which pushes the gaseous fluid out of the pump outlet along with a little bit of the liquid sealant, this is because the liquid is highly turbulent inside the pump. (6) A two stage liquid ring pump is the same as described above but with two cycles in series; so that the outlet from the first stage is the inlet of the second stage. Typical values of the vacuum pressure in a two stage pump decreases to 25 mmHg from 35mmHg in a single stage pump. This shows it is much more efficient at creating the desired low vacuum which ranges from 22.5mmHg to 750mmHg. (B) (A)Figure 1: Illustration of liquid ring pump operation (7) Liquid ring pumps are commonly used on reflux / condenser and reboiler / condenser systems. One such system is the removal of air from steam surface condensers and other industrial processes. The liquid ring pump would be employed to evacuate air and any non-condensable gases from a condenser; the gas removal is done to eliminate the insulating effect of the gases present which affects the heat transfer between the steam and cooling medium. This greatly improves the efficiency of the heat transfer system and results in a smaller condenser surface area required, therefore saving space and costs of running a larger condenser. Typically for running such systems a two-stage liquid ring pump would be favoured to create a hogging operation. The first stage of the pump is used to evacuate the air from the condenser at very high pressures and then the second stage is used to optimize the efficiency of the pump and reduce the amount of peak power required. (8) Vacuum pumps are important units in plants that are involved in many applications like processing food, plastic processes, medical process that requires, etc. There are three types of vacuum pumps which can be concluded as molecular pumps which use very high speed jet of fluid, positive displacement pumps that enlarge the cavity and seal it off in frequent and entrapment pumps that traps fluid in solids. A liquid ring pump falls under the displacement pumps category, however there difference that distinguishes it from other displacement pumps. This is due to a liquid ring being formed, it creates a high convective heat and mass transfer phenomenon which dissipates the thermal effect of compression and achieves near isothermal behaviour. The effect of instantaneous convective heat and mass transfer is so rapid that the gas outlet temperature is noted to be close to the sealant inlet temperature almost instantaneously. Because of this effect the discharge temperature remains roughly co nstant, and since the volumetric flowrate also remains nearly constant then with high suction pressure the mass discharge can be enhanced. This causes the liquid ring pump to have faster evacuation during start up and faster turnaround during cycling. (1) Liquid ring pumps can use a variety of liquids, water is the most common, and the choice is generally related to the pressure you wish to be operating at. Oil is also commonly used as a liquid sealant, since oil has a very low vapour pressure; it is typically used in air-cooled systems. The liquid ring pump is also ideally suited for solvent recovery such as toluene provided the cooling water keeps the vapour pressure of the sealant down to produce the required vacuum. Ionic fluids also can be used to reduce the pressure from about 70mbar to below 1mbar. (9) Cavitation is considered a major issue that is associated with liquid ring pumps due to the fluid environment creating low pressures. At very low pressure, 35 mmHg, water boils at 31.7 CËÅ ¡. Therefore, it is essential to keep the sealant at low temperatures by supplying a cooling water flowrate to the system. Inertial cavitation is caused when the pressure falls below the vapour pressure and cause bubbles to form. These bubbles then start to collapse due to the high pressure of the surrounding medium as the pump starts to compress. As the bubble is collapsing the pressure and temperature inside rapidly start to increase, the bubble will eventually collapse, and this releases the gas into the surrounding liquid with a violent mechanism where the energy is released in a shock-wave. This can cause a series of craters and holes along the impeller this can reduce efficiency of the pump and can be seen in figure [2]. Figure [2]: Cavitation We can see the region of cavitation caused by the outlet water temperature, absolute suction pressure and air flowrate illustrated in figure [3] below. Figure [3] Figure [3] shows how a pump can operate within a safe region and then be carried into the cavitation region with only an increase in temperature. The graph also shows how the liquid in the pump vaporizes under certain conditions. For our experiment it makes sense to control the safe operation of the pump by supplying a cooling water stream. This will keep the temperature down and out of the cavitation region. It is also easier to control as the air flowrate depends on the rig that the liquid ring pump may be connected up to. And the suction pressure will have local variation within the pump. (10) Orifice meter for determining air flowrates The flowmeter used by the DeltaV software in the control room, was used to provide data on inlet air flowrates into the liquid ring pump and was unfortunately faulty. This meant the real time recordings of air flowrates could not be supplied. Thus, calibration of the orifice meter was necessary to determine the inlet air flowrates. Figure ?: Orifice meterA square-edged orifice with radius taps was used to calibrate the inlet air flowrate into the Liquid ring pump. Pressure tappings attached to mercury manometers were located one pipe diameter upstream and one-half pipe diameter downstream from the orifice plate as shown in Figure ?. Bernoullis equation for incompressible, inviscid flow along a streamline (11) without shaft work: Where is the inlet pressure (upstream pressure in this case), Pa is the outlet pressure (downstream pressure in this case), Pa are the inlet and outlet velocity respectively, m s-1 is the density of the fluid, kg m-3 is the gravity acceleration, m s-2 , are the inlet and outlet elevation respectively, m The continuity equation gives (11) Where and are the inlet and outlet cross-sectional area respectively, m2 The volumetric air flowrate across the orifice plate can be expressed by substituting Eq.

From typical values of 0.61-0.65 (12), was used as the initial guess for iterations to take place. After three iterations, the values of between the corresponding iterations differ within an order of 10-6 and at the third iteration were used for calculations in this report. Where did the valve come from? Relate to diagram? 2,5,8,11 what? Figure 2: Calibration of inlet air mass flowrates across orifice plate give similar trend and magnitude for varying cooling water flowrates Figure 2 indicates that the varying cooling water flowrates do not affect the air mass flowrates across the orifice plate. Thus, the inlet air mass flowrates depends only on the number of turns on Valve 11.6. Average inlet air mass flowrates for cooling water at 2, 5, 8, and 11 kg h-1 were used to produce the following equation in Figure 3 which will be the calibration used in this experiment. Figure 3: Calibration of averaged inlet mass air flowrate across orifice plate Assumptions Temperature Factor Figure 4: Double Stage Pump (13) The suction pressure created falls within the range of approximately 106 to 531 torr while the temperature of sealant water used entered the pump at approximately 55 °F. These conditions fall within a region where the gradient of the graph is very gentle and the value of the temperature factor is around 1.0. Therefore, the temperature factor to be applied to the flowrate of sealant water is approximately the same even as inlet pressure changes. Also, even as the cooling water flowrate was changed, the sealant water temperature was observed to remain around 55 °F. The temperature factor to be applied would not be greatly affected by either of the two operating variables, namely the cooling water flowrate and the inlet air mass flowrate which affects the suction pressure. Since the temperature factor is approximately 1.0, it can be assumed that the mass flowrate of sealant water entering the pump and leaving the pump to be the same, making the vaporisation of air negligible. This a ssumption is investigated by performing a mass balance across the pump taking into account vaporisation of air during the compression process. Inlet air It is assumed that the inlet air into the Liquid ring pump contains no moisture, thus we refer to the inlet air as dry air. The heat exchanger is assumed to have 100% efficiency in heat transfer between the pump, sealant water, and cooling water streams. Assuming no heat loss to the surroundings, the compression work done by the pump is equal to the heat gained by the cooling water in the heat exchanger. For the purpose of calculating efficiency of the Liquid ring pump for this experiment, it is found to be more to calculate compression work from the cooling water heat gain. Steady State Vapour pressure Vapour pressure refers to the pressure in the gas phase when the liquid and gas phase of a system are in equilibrium. The vapour pressure of the sealant liquid into the Liquid ring pump plays an important role in determining the pump capacity. At higher temperatures of sealant liquid, the vapour pressure increases and more vaporisation occurs, causing a lower flowrate of air into the pump which results in low pump capacity. Although it might seem that maximum cooling of the sealant water might be a good idea, care must be taken that the sealant water temperature do not fall so low that cavitation might occur in the Liquid ring pump. [more on cavitation in limitations section] In this experiment, the temperature of the sealant liquid is varied by changing the cooling water flowrates. The relationship between vapour pressure and pump capacity is investigated. From Antoines equation, the vapour pressure of a liquid within a range of temperature can be determined (14) Where T is the temperature, K is the saturation vapour pressure, mmHg are constants for specific materials. For an air-water system, the standard Antoine coefficients are A=8.05573, B=1723.64, C=233.076  °C, valid between temperatures of 0.01  °C and 373.98  °C. (15) A relationship between the vapour pressure and temperature can be obtained from the Clausius-Clapeyron equation (16) Where T1 and T2 are temperatures at condition state 1 and state 2 respectively, K and are vapour pressures at T1 and T2 respectively, Pa is the heat of vaporisation, kJ/kg Isothermal System work done across T2 to T4 equals T7 to T6 T4,6,7? The compression process of a liquid ring pump can be approximated to an isothermal operation at inlet sealant water temperatures. (1) During compression, mechanical energy is converted to compression work and dissipated as thermal energy. The liquid ring formed in the pump provides high heat convection and mass transfer which dissipates the thermal energy, creating a near-isothermal operation. This phenomenon occurs in such a short time scale that the system reaches equilibrium rapidly, and the outlet gas temperature approximates the inlet sealant liquid temperature. Mallick (1) describes this as an achievement of highest degree of thermodynamic efficiency of compression. [Need temperatures to prove this] Compression work From the First Law of Thermodynamics, isothermal compression work of an ideal gas can be expressed by (16) Where W is work, J P is absolute pressure, Pa V is total volume of the system, m3 Assuming ideal gas behaviour applies (verify this!), Where m is mass, kg V1 is the inlet volume, m3 V2 is the outlet volume, m3 R is the gas constant, Pa m3 kg-1 K-1 T is the temperature, K For an isothermal system (17) PV = constant Where Wc is the compression work, J Equation ? is divided by time t, to express the compression work, Substituting = m/t = à Ã‚  Where is the mass flowrate, kg s-1 t is time, s And equation ? in equation ?, the compression work of a vacuum pump at any pressure P, for an isothermal system can be derived to be (4): Where is the pumping speed of the liquid ring pump is the theoretical power consumed for an isothermal process, kW Pump efficiency The efficiency of the liquid ring pump is a vital factor in deciding the suitability of the pump for its purpose. Through experimental investigation, we varied cooling water flow rate and air mass flow rate to determine the condition where the liquid ring pump is the most efficient. From theory, we have assumed an isothermal operating condition which leads us to calculating the efficiency, of the pump as: Where Wiso,c is defined as the compression work done under isothermal conditions Wactual,c is defined as the enthalpy gain and Wactual,c = m Cp ΆT.

Figure 5: Title (19) 3.0 Mass and energy balance 3.1 Mass balance During compression in the liquid ring pump, mechanical work is converted to thermal energy and dissipated, potentially vaporising the sealant water used for compression. Assuming the inlet air is dry air with no water content, the mass balance across the LRP is: Mass balance on the gas component Assuming This can be rearranged to give Where is the humidity ratio obtained from the psychometric chart for the air-water system at standard atmospheric pressure (20).

Substituting the relation And Where h is the specific enthalpy, kJ kg-1 The energy balance equation reduces to Which is Where and are the inlet and outlet mass flowrates respectively, kg s-1 and are inlet and outlet specific enthalpy respectively, kJ kg-1 Methodology Apparatus Figure 6: Process Flow Diagram of Experimental Set-up Liquid Ring Pump Sealant Water Tank Scrubber Thermocouples Mercury Manometers Rotameter Orifice Plate DeltaV system Experimental design Firstly, we identified two operating variables that could be varied to investigate the performance of the pump. The two variables are the inlet air flowrate and the storage tank cooling water flowrate. The inlet air flowrate could be manipulated by a flow control valve over a range of 8 to 70 turns. By calculating the pressure drop across an orifice plate and plotting a calibration curve, we were able to get the mass flowrate associated with the number of turns on the valve. The storage tank cooling water could be manipulated over a range of 0.5 to 12.5 m3h-1. The adjacent flowmeter gives a measurement of the cooling water flowrate into the heat exchanger around the sealant water storage tank. A full set of measurements were taken to obtain pressure, flowrate and temperature data as we changed the operating variables. Pressure data was obtained for the pressure drop across the orifice plate, and the suction, interstage and outlet pressures for the pump through mercury manometers. Flowrate data was taken from a rotameter that measured the volumetric flowrate of the sealant water. Temperature data was extracted by the DeltaV logging software in the control room. Experimental Procedure The following procedure was conducted over two experimental runs. Through repeating the procedure, we were able to test the reproducibility of our results and reduce the effect of random errors on our results. Set and maintain cooling water flowrate at 2m3hr-1. Starting with the maximum air flowrate at 70 turns we waited for steady state to be achieved before taking the manometer readings for suction, interstage, outlet, orifice plate and rotameter readings for the sealant water flowrate. The air flowrate was then decreased to 60 turns followed by 50, 40, 30, 20 and 10 turns, all the while ensuring that steady state is reached before taking the readings. The full range of measurements from 70 to 10 turns for the inlet air flowrate was similarly taken at cooling water flowrates of 5, 8 and 11m3hr-1. Limitations In determining if the system is at steady state, the flowrate readings that can be monitored from the control room will provide good indication once the rate stabilises. However, the range of the flowmeter is limited beyond 119m3/hr (between 40 and 50 turns on V11.6). Therefore, the mercury manometer that reads the pressure drop across the orifice plate should be used to determine steady state after 40 turns on V11.6. A calibration curve will be plotted to relate the inlet air flowrate and the pressure drop across the orifice plate for mass flow calculations. Also, the flowmeter was faulty on our second run which meant that we would have to solely depend on our calibration curve to determine the inlet air mass flowrate at any number of turns. Analysis of results In the investigation of the performance of the two stage liquid ring pump, we ran the pump under different operating conditions by varying two variables; the air mass flowrates into the pump and cooling water flowrates. Pressures of the suction, interstage and outlet of the pump were measured and used to evaluate the pumps performance at different conditions, hence determining the efficiency of the pump. As the behaviour of inlet air mass flowrate, sealant water flowrate, suction pressure, compression work and pumping speed showed almost identical trends for different cooling water flowrates, an average of the four measurements were used. Sealant Liquid The sealant liquid used in the experiment is water and the compressed fluid is air. Before starting the run, the pump is filled with a specific level of water to ensure that there is sufficient sealant liquid to create vacuum. As the sealant fluid shares the same space in the pump as the fluid to be compressed, it would be expected that as the flowrate of the latter is increased, the flowrate of the sealant liquid decreases. Figure 7: Average Sealant Water Flowrate vs Inlet Air Mass Flowrate From figure 7, it can be seen that as the inlet air mass flowrate increases, the sealant water flowrate into the pump decreases. This is in line with the expected trend since the compressed air occupies a much greater volume in the pump at higher air mass flowrates. Suction Pressure Vacuum is created by the liquid ring pump due to the pressure difference between the source and the pump inlet. In the experiment, the source is air at atmospheric pressure and the inlet pressure is the suction pressure created by the pump. A low suction pressure would translate to a big pressure difference, creating vacuum. (21) Figure 8: The average inlet air mass flowrate for varying cooling water flowrates was plotted against suction pressure Figure 8: shows the trend we obtained where suction pressure increases as inlet air flowrate is increased. This shows that at lower air flowrates, more vacuum is created at a low suction pressure. As the air flowrate is increased, the ability to create vacuum decreases resulting in a higher vacuum pressure. Figure 9: The relationship between dry air capacity and suction pressure at a temperature of 20  °C obtained from literature. (22) As it is assumed that dry air is used and that its density remains constant throughout, the experimental results in Figure 8 can be compared to results obtained from literature in Figure 9. A similar trend is observed where there is the suction pressure is greater as the dry air capacity increases. Figure 10: Table categorising the degree of vacuum according to the absolute pressure of operation. (23) This experiment operates within a range of suction pressures which averages to approximately (1.41-6.00) x104 Pa abs. From figure 10, the range categorises the liquid ring pump as one that creates low vacuum. Low vacuum is sufficient in many industrial applications such as distillation in the petrochemical industry which keeps the liquid ring pump as a relevant piece of plant equipment. Compression Work (Sample calculations for a cooling water flowrate of 11 m3h-1 at 30 numbers of turns) shifted to appendix To calculate compression work under isothermal conditions, we can use Equation 3.7.11 Figure 12: shows that greater compression work is done by the pump with increasing suction pressure. From figure 12(above), it can be seen that greater compression work is done with increasing suction pressure. Based on the inlet air mass flowrate that we used, the suction pressure we created with the pump ranges from ~106 to 531 torr. The graph of the suction pressure against compression work shows a similar trend to literature values shown below in figure 11(below) for the same range. Figure 11: Effect of suction pressure compression work (4) Removed figure 13 Effect of Inlet Pressure on Pumping Speed Figure 15: Pumping Speed at different temperatures of sealant liquid (4) It can be seen from the graph Figure 15 that the change in pumping speed gradually becomes smaller. The inlet pressure (suction pressure) that we obtained from varying the inlet air mass flowrate falls within the range of around 106 to 531 torr. Therefore, we should obtain the same trend of pumping speed with increasing inlet pressure. Figure 16: Pumping speed changes with increasing suction pressure Replaced the graph with a newer one showing the right denotation for units on the y axis Figure 16 shows that the experimental results obtained agree with results obtained from literature. With increasing inlet pressure, the pumping speed increases while the gradient of the graph decreases. 5.5 Efficiency Figure 17: Plot of Isothermal Efficiency Vs Sealant Water Mass Flowrate Figure 17 shows that isothermal efficiency decreases with increasing sealent water flowrate. This result agrees with theory as we know from theory, the efficiency of the pump is affected by the vacuum capacity, and with an increase in sealent water flowrate, more vapour will be formed from the increased amount of sealent water forming the ring-liquid when the vacuum pressure approaches the vapour pressure of the sealent liquid. The increase in vapour volume released from the increase in sealent water will decrease the vacuum capacity and therefore reducing efficiency. Figure18: Plot of Efficiency Vs Cooling Water Flowrate Figure 18 shows that a higher cooling water flowrate will result in higher efficiency. The above trend is derived from the isothermal efficiency of the system at a fixed sealant water flowrate of 0.27 kg s-1. The cooling water flowrate is related to the enthalpy gain of the sealant water and consequently the isothermal efficiency. A higher flowrate would mean that the enthalpy gain is lower and that isothermal efficiency is higher which can be seen from equation 2.8.1. From the above results we can therefore conclude that the liquid ring pump is most efficient at the highest cooling water flowrate and a sealant water flowrate of 0.27 kg s-1 which translates to air flowrate at 60 turns flowing into the pump.
