Public Schools Vs. Canadian Schools - 1668 Words

While there are of coarse similarities between the residential school system and the Canadian pubic school system, there are many major differences. Residential schools were introduced back in the 1870’s, they were made to change the way native children spoke their languages and how they viewed their cultures. The residential school system in Canada was operated by the government, where the native children were aggressively forced away from their loved ones to participate in these schools (â€Å"1000 Conversations†). The government had a concept, where â€Å"they can civilize and Christianize Aboriginal people, whose traditional ways of life were seen as inferior or heathen† (Mccue). They aimed for the children aged of three to eighteen to†¦show more content†¦As they planned this idea with the churches across Canada, it became an unforgettable event for the native people. â€Å"The implementation of the Indian Act (1876), the government was required to provide Aboriginal youth with an education and to integrate them into Canadian society† (Miller). These schools changed the way native people lived in Canada. The children in these schools were abused and neglected everyday as a punishment. The reason for this is that the students would talk to other students in their native languages and this caused mayhem for teachers to abuse them in terrible ways. They were hit by sticks and they would use anything else as a weapon to teach them a lesson (Hanson). The treatment in these schools were awful that some were physically changed in appearance. The teachers would give them verbal abuse as well if they continue to do small mistakes. The treatments the children were given resulted in really high death toll rates (Hanson). As this continued the Canadian government wanted to â€Å"kill the Indian in the child† (Hanson) to modernize the native children. It was a rule of the government so they can have no native cultures left in the future and remove the unwanted languages of the past. While this is the case, students in the Canadian public schools were not treated horrifically, like the students were in the residential schools. Teachers had become more mature and gave

The Brightest Of Her Age - 1234 Words

The Brightest of Her Age: How Author JK Rowling Triumphed Over Poverty, Depression, and Became one of the Most Successful Authors in History Before Harry Potter was a best-selling novel, with a multimillion dollar business, a theme park, and several movies to its name, The Boy Who Lived was no more than an a couple of sentences, scribbled between the pages of a notebook. Long before her rise to fame, J.K. Rowling, author of history’s best-selling fantasy series, spent several years in as a single mother fighting her way out of poverty. Within the span of five years, Rowling went from relative poverty, to the world’s first, and only, billionaire who made her fortune from selling books. Hers is the literal rags to riches story. However, her tragic past hasn’t hindered Rowling in the slightest. In addition to publishing seven books in the Harry Potter series, two crime novels, and several tie-ins that expand the magical world of Harry Potter, Rowling has become an active philanthropist.

Outsourcing free essay sample

Use the theories of international trade and investment that have been presented in this chapter to help explain Brazil’s intentions and actions regarding the international information technology sector. International trade theory shows that nations will attain a higher level of living by specializing in goods for which they possess a comparative advantage and importing those for which they have a comparative disadvantage. For Brazil, they have launched an active campaign to build a strong international competitive position in the IT off-shoring business, trying to attract business that might otherwise be going to these other nations or regions. They have a sophisticated telecommunications and network availability. They also have a strong engineering school and capable of producing high quality technical graduates. Employee turnover is only about 20 percent, versus the 40 percent rate in India. They are only a single time zone difference from the east coast of the United States compare to the rest of the world.

The recommendation I would give the Brazilian government would offer scholarship to student in IT sector but with some form of contract. What I mean all these inner city or poor children who are smart but don’t have the means to pay for an education. Like the U. S. Army, you can sign up for a minimum of three years and get money for education. Well the government can offer that they will pay for their education, but when they graduate they will work the first three years for them. Start to offer more English speaking class for elementary school all the way up to the corporate business men. Brazil also has problems in term of crime and social inequality, especially in the big unban center such as Rio de Janerio and Sao Paula. In these two cities I would offer programs that will clean up the community. We know we have to start with one section at a time, so build community center that offer before and after school programs that would encourage children into the IT business. The government should also invest money in electrical engineer, since the country is prone to brownout and blackout problems. I believe if they invest in these things, in the future Brazil will be one of the top IT competitors in the global market.

Montaigne Essays - Philosophy, Epistemology, Epistemologists

Montaigne Montaigne in his Apology for Raymond Sebond begins his exploration into the human capacity for knowledge with this belief that only though God can one achieve true knowledge. God is the only infinite, all seeing, being with divine wisdom. He is not subject to the laws and rules of the human domain, and he exists in a realm outside of human comprehension. God is an unchanging, permanent being, and only from this state can the concept of truth propagate. Montaigne believes that the one tie that binds all truth is this idea of permanence. Montaigne even states, ?Truth must be the same everywhere? (xxvi). He insists that the only product of humanity that has withstood the test of time and has not changed since its inception was the Catholic Church. The dogma of the Catholic is categorized as, ?What has been held always, everywhere by all?. The strength in the Catholic faith comes from its static nature, which provides a source of truth for humanity. Catholic truth is in strict conformity with the existence of God, and knowledge can only come from an almighty source. Montaigne goes on to say that, ?No creature ever is: a creature is always shifting, changing, becoming.? Man embodies the idea of impermanence. He is fragmented, does not have divine reasoning abilities, and has a finite amount of time allotted to him. Human reasoning, which creates the concept of knowledge, is in direct confrontation with the qualities of truth. Plato Aristotle, and Sexius Empiricus all conceded the fact that when it comes to the human being, there is no exact standard of truth. All humans view the concept of truth differently, and thus, it can only be associated to an opinion. Like wise a mortal man cannot know everything there is to know about a certain being, or structure or thing. He cannot possibly know the inner workings of such thing only through the use of his senses, he can only for his own opinions. Opinions in a finite domain are susceptible to different interpretations and uncertainty, and what is true for one person does not necessarily have to hold true for another. Thus, the concept of truth derived by man is ridden with inconsistencies, all of which are in direct violation with the very definition of truth. Since the building block of human knowledge is this flawed truth, then human knowledge itself is flawed. Simply put, the concept of human knowledge is false and consequently knowledge cannot exist. Knowledge is just an opinion taken for the truth, and can be seen as only one side in an ever evolving story. Just think of what we considered the book of human knowledge today. No matter in what aspect of life one considers whether it be math, physics, biology, history, or computer science there is never really any truth. The book of knowledge is rewritten daily as new opinions enter the foray, and will never be as static or held as high as divine truth. Although we have established the fact the knowledge cannot exist from the human standpoint, it is this concept that all of mankind believes in most deeply. From a man's perspective, it is our knowledge, which sets us apart from the rest of the animal kingdom. The fact that we can communicate to each other the knowledge of our thoughts and ideas is the dividing line between man and beast. However, Montaigne is in strict disagreement with this rational and believes the only the inese sense of vanity displayed by all humanity separates men from the rest of the animals. Montaigne flatly states that, ?That of all vain things, Man is the most vain; that a man who dares to presume that he knows anything, does not even know what knowledge is? (Montaigne 13). He characterizes man as being the most vain of all his creatures because he clings to this notion of knowledge and that though this attainment of knowledge he perceives himself as enlightened. Montaigne then shows the absurdity of this claim by taking a hypothetical situation in which Man is in isolations with not outside help and stripped of the ?grace and knowledge of God? those things that are his power and the very

Political Parties and the Facebook Founder

Political Parties and the Facebook Founder Mark Zuckerberg says hes neither a Democrat nor a Republican. But his social media network, Facebook, has played a huge role in American politics, particularly the election of Donald Trump in 2016. Zuckerberg Isnt Affiliated With a Major Party Zuckerberg is registered to vote in Santa Clara County, California, but does not identify himself as being affiliated with the Republican, Democrat or any other party, according to a 2013 report in the Wall Street Journal. I think its hard to affiliate as being either a Democrat or a Republican. Im pro knowledge economy, Zuckerberg said in September 2016. Facebook Political Action Committee The Facebook cofounder  and his companys  political action committee  have  given tens of  thousands of dollars to political candidates of both parties in recent years, a relatively small amount relative to the vast sums of money flowing through the election process. Yet the billionaire’s spending on campaigns does not tell us much  about his political affiliation, a topic of much speculation. Zuckerberg is a major contributor to Facebook’s political-action committee, called Facebook Inc. PAC. He’s given $25,000 to the PAC since 2011, according to federal records. The Facebook PAC raised nearly $350,000 in the 2012 election cycle. It spent $277,675 supporting federal candidates; Facebook spent more on Republicans ($144,000) than it did on Democrats ($125,000).   In the 2016 elections, Facebook PAC spent $517,000 supporting federal candidates. In all, 56 percent went to Republicans and 44 percent went to Democrats. In the 2018 election cycle, Facebook PAC spent $278,000 supporting candidates for federal office, mostly on Republicans, records show. Zuckerberg did, however, give his largest one-time donation to the Democratic Party in San Francisco in 2015 when he cut a check for $10,000, according to Federal Election Commission records. He has sharply criticized President Trumps Republican immigration policies, saying he was concerned about the impact of the presidents first executive orders. We need to keep this country safe, but we should do that by focusing on people who actually pose a threat, Zuckerberg wrote on his Facebook page. Expanding the focus of law enforcement beyond people who are real threats would make all Americans less safe by diverting resources, while millions of undocumented folks who dont pose a threat will live in fear of deportation. Zuckerbergs large donation to Democrats and his criticism of Trump have led some to the conclusion that the Facebook CEO is a Democrat. But Zuckerberg did not contribute to anyone in the 2016 congressional or presidential races, not even Democrat Hillary Clinton. He also stayed out of the 2018 midterm elections, records show. But Zuckerberg and Facebook have  nonetheless come under intense scrutiny for the social networks outsized influence on American political discourse, in particular its role in the 2016 election. Campaign Contributions to Republicans and Democrats Zuckerberg himself has contributed to:   Sean Eldridge: Zuckerberg contributed the maximum $5,200 to the Republican House candidate’s campaign committee in 2013. Eldridge is husband of Facebook co-founder Chris Hughes, according to the National Journal.Orrin G. Hatch: Zuckerberg contributed the maximum $5,200 to the Republican senator from Utah’s campaign committee in 2013.Marco Rubio: Zuckerberg contributed the maximum $5,200 to the Republican senator from Florida’s campaign committee in 2013.Paul D. Ryan: Zuckerberg contributed $2,600 to the failed 2012 Republican vice presidential nominee and House member in 2014.Charles E. Schumer: Zuckerberg contributed the maximum $5,200 to the Democratic senator from New York’s campaign committee in 2013.Cory Booker:  Zuckerberg also contributed $7,800 in 2013 to the  prominent member of the Democratic Party and senator  who is widely believed to be a leading candidate for president as soon as 2020. But  Zuckerberg  sought and received a full ref und for unexplained reasons. Facebooks Role in the 2016 Election Facebook has drawn fire not for its or its founders campaign contributions, however, but for its business practices. The company has been criticized for allowing partisan third parties (one of which had ties to the Trump campaign) to collect data about users, and for allowing its platform to serve as a tool for Russian groups seeking to sow discord among the American electorate. Zuckerberg was called to testify in his own defense before members of Congress who had express concern for user privacy. The companys largest controversy to date has been the disclosure, first reported by The New York Times, that a political consulting firm harvested the data of tens of millions of Facebook users, information that was later used to build psychological profiles of potential voters in 2016. The firm, Cambridge Analytica, worked for the Trump campaign in 2016. Its misuse of the data prompted internal investigations by Facebook and the suspension of about 200 apps. Facebook was also hammered by policymakers for allowing the  proliferation of misinformation, often called fake news, across its platform- misinformation that was designed to disrupt the election process, government officials have said. A  Kremlin-backed firm called the  Internet Research Agency purchased thousands of derogatory Facebook ads as part of its operations to interfere in elections and political processes,† federal prosecutors allege. Facebook did little, if anything, to discourage the spread of misinformation before and during the campaign. Zuckerberg and Facebook launched efforts to take down fake accounts and misinformation. The social media cofounder told members of Congress the company previously didnt take a broad enough view of our responsibility, and that was a big mistake. It was my mistake, and Im sorry. I started Facebook, I run it, and Im responsible for what happens here. Political Advocacy Zuckerberg is among the tech leaders behind FWD.us, or Forward U.S. The group is organized as a 501(c)(4) social welfare organization under Internal Revenue Service code. That means it can spend money on electioneering or make contributions to super PACs without naming individual donors. FWD.us spent $600,000 on lobbying for immigration reform in 2013, according to the Center For Responsive Politics in Washington. The group’s primary mission is to get policy makers to pass comprehensive immigration reform that includes, among other tenets, a pathway to citizenship for the estimated 11 million undocumented immigrants currently living in the United States who do not have legal status. Zuckerberg and many tech leaders are lobbying Congress to pass measures that would allow for more temporary visas to be issued to high-skilled workers. The contributions to individual members of congress or candidates listed above are examples of his support for those who back immigration reform. Zuckerberg, though he personally has contributed to Republican political campaigns, has said the FWD.us is nonpartisan. â€Å"We will work with members of Congress from both parties, the administration and state and local officials,† Zuckerberg wrote in The Washington Post. â€Å"We will use online and offline advocacy tools to build support for policy changes, and we will strongly support those willing to take the tough stands necessary to promote these policies in Washington.†

Biochemistry science field Research Paper Example | Topics and Well Written Essays - 2500 words

Biochemistry science field - Research Paper Example Therefore, it may be hypothesized that the use of cartilage in the promotion of endochondral regeneration of bones may leverage normal development and repair sequences resulting in a properly vascularized regenerate capable of integrating with the host tissues. Various tests have demonstrated that cartilage grafts are able to support the regeneration of vascularized and integrated bone tissues in vivo, while lineage tracing experiments have revealed graft derived regenerates. Mesenchymal stem cells are actually the pluripotent cells existing in numerous adult human tissues, for example bone marrow and adipose as well as synovial tissues, and since they originate from the mesoderm, they differentiate to become bones and cartilage as well as muscles and adipose tissues (Nolta, 2006). Mesenchymal stem cells from embryonic sources have demonstrated probabilities in science while at the same time creating a considerable amount of controversy. As a consequence, numerous researchers have put emphasis on adult stem cells or those isolated from human adults that may be transplanted in to tissues that are damaged. As a result of their multi-potent capability, mesenchymal stem cell lineages have been employed with success in animal models in the regeneration of articular cartilage and in human models in the regeneration of bones. Research done recently has shown that articular cartilage can be repaired through percutaneous introduction of mesenchymal stem cells. Th is paper aims at explaining how bone and cartilage can be differentiated from stem cells as well as considering the current research and development of this discipline. An experiment that sought to investigate conditions that can stimulate stem cells to differentiate into fat of bone cells while being encapsulated by hydrogels was conducted with polymer networks, which could simulate various conditions where the stem cells grow naturally. The first step in growing the new cartilage involved initiating

Funeral Oration and Old Oligarch Essay Example | Topics and Well Written Essays - 500 words

Funeral Oration and Old Oligarch - Essay Example In the wake of the Peloponnesian War, scores of Athenian soldiers were pressed into duty who they readily endured the hardships of warfare. Though acknowledging their bravery and sense of duty, Pericles notes that one individual’s words cannot sufficiently capture the magnitude of their feat. Pericles goes on to mention how the very foundation of the Athenian kingdom was based on valour and patriotism. He cites the example of martyrs from previous generations to identify this tradition. Pericles assures the audience that the great courage exhibited and the great human loss thus incurred was not in vain. The city of Athens is a crown jewel of civilization and culture. According to Pericles, the endeavour to protect the sanctity of this great city from marauding invaders was a noble project, for, in consequence, it protects the institutions of democracy within the city. His elogà © then is not just for the recently martyred, but also for their exemplary forbears and the proud democratic traditions that the city stands for. He concludes his speech by exhorting the audience to live up to the standards of the martyrs as well as uphold the spirit of democracy that Athens has become synonymous with. The Old Oligarch takes a totally different view of Athens, especially its Constitution. He reckons that democracy can easily lead to mob-rule. The author believes that the aristocracy is endowed by nature with qualities necessary for leadership. Taking away the reigns from them could so easily lead to disintegration of law and order. Their privilege in acquiring sound education is a valuable asset for statecraft. Likewise, the material abundance into which the aristocracy are born lends them skills for managing the economy of the city. Pseudo-Xenophon worries that if the poor are given a voice in public affairs the natural order of the

Greek or Shakespearean Essay Example for Free

Greek or Shakespearean Essay The essential component to any tragedy, Greek or Shakespearean, is a protagonist with a fatal flaw. In Greek tragedy this is called hamartia. This Latin term translates directly into the word â€Å"flaw† but is usually used to describe an excess of a personality trait virtue or vice. The protagonists fatal flaw pushes the the plot and action of the tragedy forward. It is this tragic flaw, which leads to the eventual downfall of the character, his circumstances, and the denouement of the drama. In examining the bulk of the literatures protagonists, no other character embodies the essential role of the flawed protagonist like Hamlet. Hamlets fatal flaw is his idealism. Only once Hamlet overcomes his idealism is he able to seek his revenge. The climax of the play occurs with Hamlets realization that the world is not as it seems and that he must shrug off his idealistic values and avenge his fathers murder Act 3, scene 4. In Shakespeares Hamlet, act 3 scene 4, is a pivotal scene within the play. The scene begins in the Queens chamber, as Hamlet slams the door open, with sword in hand. They engage in a dialogue of riddles combined with Hamlets mishandling of the weapon makes the Queen uneasy. Hamlet is upset at the Queen for marrying his fathers brother. The Queen screams Thou wilt not murder me? Help, ho! and as Polonius responds, Hamlet promptly shoves his sword into the curtain where Polonius hides and swiftly kills him. Hamlet wonders if it was the King, half hoping that it was Claudius, who Hamlet has been trying to kill the whole play. He fantasies about killing him, in the previous scene, he states In th incestuous pleasure of his bed. Hamlet is consumed by the idea of Claudius and Gertrude making love. Once he knows that he only killed Polonius he continues to scold him mother. She responds In th incestuous pleasure of his bed and Hamlet replies A bloody deed. Almost as bad, good mother, As kill a king and marry with his brother. Again Hamlet contrasts the two brothers that Gertrude has become involved with. Hamlet must avenge his fathers death. In doing so he must not only kill Claudius but also resurrect his father. He does this by outlining how his fathers good qualities compare to his uncles bad qualities. Hamlet laments: Look here upon this picture, and on this, The counterfeit presentment of two brothers. See what a grace was seated on this brow, Hyperions curls, the front of Jove himself,. . . This was your husband. Look you now what follows. Here is your husband, like a mildewd ear Blasting his wholesome brother. Hamlet contrasts the two brothers which he claims are completely the opposite. Hamlet believes that Gertrude might has mistaken one for the other. Hamlet continues to verbally assault his mother. Much of what he says is a rephrasing of Hamlets first solioquy, frailty thy name is woman as well as Hamlet aggressive behavior toward Ophelia in the nun scene. Act 3, scene 4 is the part of the play when the climax happens. Hamlet must first confront the cause of this murder, Queen Gertrude. It is within in this scene that Hamlet gets his first taste of vengenance and murder when he easily kills Polonius. After this murder, Hamlet decides he can and must kill his fathers murderer, Claudius. However, Hamlets leaves his mother alone because his fathers ghost appears and advises Hamlet to Leave her to heaven. Hamlet respects and loves his father in life and also in death and adheres to the ghosts advice. Hamlets goal is to bring back his fathers reign not just by pointing out Claudius faults but also by humiliating his mother and her new world to trash. Hamlet continues: Have you eyes? Could you on this fair mountain leave to feed And batten on this moor? Ha, have you eyes? Hamlet is trying to convince his mother give up her new life with Claudius, to find her loyalty to her dead husband, and back to the way things used to be. Hamlet takes the role of scourge and minister, and tells her she can redeem herself from being a whore to being the good wife she used to be. Hamlet advises her to leave Claudius, â€Å"the moor† and climbs up on her dead husbands â€Å"mountain†. Hamlet explains â€Å" throw away the worser part of your cleft heart, Hamlet instructs her, And live the purer with the other half. However, Hamlet, as much as he wants to love his mother, can not get past his belief that she is responsible for his fathers death. It is important to note that this scene takes place in the Queens bedroom. The conversation symbolized Hamlet and Gertrude essentially â€Å"in bed† together and hints to a sexual relationship. Hamlet speaks like a jealous lover chastising his girlfriend for sleeping with a different man and making their bed â€Å"enseamed†. The Queen is extremely upset and actually asks Hamlet to help her figure out what to do. At this point when Hamlet should have told her to confess, he urges her to stop her relationship with Claudius, Not this, by no means, that I bid you do: Let the bloat king tempt you again to bed (Act III, sc iv). It is in the moment that Hamlet allows his emotion to dominate over his intellect that Claudius was killed. He is consumed by the thoughts of his fathers demise and is haunted by the knowledge that his fathers soul will not be able to rest until his death is avenged. Hamlet willfully concludes, My thoughts be bloody or be nothing worth (Act IV sc iv). It is then that Hamlet finally had the ability to suppress his idealistic nature, and do what is right. The murder is not a well planned scheme and occurs in the heat of the moment. Hamlet, after the murder of Claudius never once wavers in his decision. He has done what is right and believes that There is a special providence in the fall of a sparrow (Act V sc ii). Hamlet is able to do anything but take vengeance upon the man who did away with his father and has taken his father’s place with his mother. The pain which should have caused him to take immediate revenge was replaced by pity for himself. It is Hamlets idealistic nature that creates the ultimate theme and driving force behind all the rising action, falling action, and resolution of this tragedy as well as the death of his mother. The way in which Hamlet views his mother, father, and Claudius is finally revealed in Act 3, scene 4. Once Hamlet is able to be honest about his feelings, he is able to finally seek revenge for his fathers murder. This scene is pivotal to denouement of the play and essential to Hamlets transformation from a boy to man who embodies the important qualities which were cherished and expect by an Elizabethan audiences.

Marketing MA Management and International Business Essay -- Business a

Marketing MA Management and International Business Introduction CRM is a term for methodologists, technologies and e-commerce capabilities -used by companies to manage customer relationships. (Foss, 2001:1) It is also called customer management, customer care and sometimes customer centricity or customer-centric management. (Brown, 2000:1) All the names and definitions of CRM have customer, as its core-it is the management of customer relationships, which attempts to revolutionize marketing and reshape entire business models. To survive and grow the business must make a profit. To make a profit it has to find people who are willing to pay more for its products/services than they cost. Therefore profit comes from customers. All Profit comes from customers So if no profit=no business And no customers=no profit Then no customers=no business Therefore customers ARE the business The idea of CRM is not new-it was the way the local shopkeeper treated his customer-he knew him, knew what was happening in his life, what he was buying, (one to one marketing?) etc. What is new though is that nowadays the retailers try to establish dialog with tens of thousands or even millions of customers in an attempt to understand them better, their individual needs and maximise the lifetime value of this relationship. In this respect it is not ‘revolution’ of marketing, but rather ‘evolution’. The old model of doing business is back into action but armed with technology and different schemes to reach the customer and retain them for life. The four types of CRM programmes, described by Stanley (2000) are aimed at enabling the company to win back customers, who have defected or are planning to, (Win Back or Save), to create loyalty among customers (Retail Loyalty), to up-sell or cross sell services to these customers (Cross Sell/Up-Sell) and to prospect for new customers (Prospecting) Retail Loyalty "Loyalty is a feeling or attitude of devoted attachment and affection; or the act of binding oneself (intellectually or emotionally) to a course of action. (http://dictionary.reference.com) In everyday life loyalty implies emotional commitment to family and friends, fidelity in marriage. It also suggests monogamy-one choice above all others.

Hersey’s Purpose in Writing Hiroshima

John Hersey was born in China on June 17th, 1914. John Hersey wrote the book Hiroshima on August 31, 1946. The book is about six survivors from the bombing of Hiroshima. The survivors was: Mrs. Hatsuy Nakamura, Dr. Terufumi Sasaki, Father Wilhelm Kleinsorge, Toshiko Sasaki, Dr. Masakazu Fujii, and Reverend Kiyoshi Tanimoto. These survivors were very strong people. They had to live off any resources that were left. Hersey wrote the book to tell the effects of the nuclear weapon. So he chose those 6 people. He described the pain that was visible. He also told about how much destruction the bomb had caused. Hersey also told the readers about how many people had died and te conditions they were in. The bomb caused exscrutiating burns all over their body. Many of the people that didn't die from the bomb was sickened with nausea, headaches, diarrhea, malaise, fever and other symptoms. It killed ninety-five per cent of the people within a half-mile of the center, and many thousands who were farther away. Hersey explained in the book the moment that the bomb was dropped on Hiroshima.Hiroshima was also written to tell about the rumors that were going around about what had just happened in their town. The book also explained how the bomb surviors was able to put their lives back together with all their injuries and the scarceless resources. It also tells about how all the survivors had to work together to survive. Hersey also tells the readers about how the survivors are today. He found out that two were dead. Another was a nun. One of them had started touring the U.S.A for money so he could rebuild his church. Another had become a surgeon in his own clinic. No description about the last survivor. So as you can see the book Hiroshima was very helpful. It helped see the effects of the bomb. Also, it helped described the pain that it caused outside of the body and inside. It also gives assistance to the scientist to see how much destruction in the a town that the bomb had caused.

Cardiac case studies Essay

CS 2: 15 points K.R. is a 46-year-old man admitted to the emergency department with unremitting chest discomfort. The pain started while he was shoveling snow from his walkway. He had experienced chest discomfort with activity previously, but the pain had subsided with rest and he sought no medical help. This time the pain did not subside and became increasingly severe, radiating to his left arm and lower jaw. In the emergency department, an ECG and cardiac enzymes were obtained. The cardiac monitor showed sinus tachycardia with occasional premature ventricular complexes. K.R. was treated with 2 L nasal oxygen, tissue plasminogen activator, sublingual nitroglycerin, and IV morphine sulfate. When he was pain free, he was transferred to the cardiac unit for monitoring. Discussion Questions 1.What changes in â€Å"cardiac enzymes† would be consistent with a diagnosis of MI? Troponins(I and T specific to cardiac muscle cells), elevated between 4-6 hours after the inset of an acute MI and remains elevated for 8-12 days. Myoglobin-level increase within 1-4 hours after the onset of chest pain and highly sensitive but not very specific. 2.What is the most common precipitating event for MI? In the most cases of MI plaque rupture followed by thrombus formation at the site is the precipitating event. 3.What is the rationale for using tissue plasminogen activator in the management of ACS? Tissue plasminogen activator if fibrin specific. It binds to the fibrin of fresh clots and the resulting compound converts adjacent plasminogen into plasmin creating localized thrombolysis. 4.Why are morphine and nitroglycerin used to manage ischemic chest pain? It’s a high priority to truce myocardial stimulation by the sympathetic nervous system. Morphine sulfate reduces anxiety and catecholamine secretion and it can reduces preload. And nitroglycerin decreases preload and reduces MVO2. CS 3 15 points: C.J. is a 16-year-old high school student who is in the  clinic for a sports physical prior to beginning basketball practice. He has no known significant medical history, takes no medications, and has no allergies. A review of systems reveals only that C.J. gets â€Å"winded† earlier than most boys on the team. He attributes this to needing to get in better shape. The physical exam is unremarkable except for a grade III systolic murmur heard over the entire precordium. An echocardiogram and cardiac cath reveals a ventricular septal defect (VSD) with moderate pulmonary hypertension.Discussion Questions 1.A VSD is usually an acyanotic defect. Why is this?  The blood being shunted is oxygenated blood from the left ventricle shunted to the right because pressures on the left are higher. 2.What is the mechanism and significance of pulmonary hypertension? The mechanism of pulmonary hypertension is due to increased blood volume within the pulmonary circuit form the VSD. Pressure is the product of CO and vascular resistance. From this case pressure is high secondary to increased CO and the primary pulmonary hypertension, the cause is increased pulmonary vascular resistance. Pulmonary hypertension can lead to cor pulmonale and right-sided heart failure. 3.What other disorders besides VSD can produce a systolic murmur? How can character of the murmur and pattern of radiation be used to differentiate among these etiologic factors? Systolic murmurs can be produced by mitral valve prolapse, aortic or pulmonary stenosis, and mitral or tricuspid regurgitation. Heart sounds are produced in some different areas of the heart and have different characteristics: Aortic stenosis- right second intercostal space, mid systolic, crescendo decrescendo and radiates to the neck. 4.Is it necessary to close a VSD? What are the common complications of untreated VSD? No, it is mot always imperative to close VSDs spending on patient’s age,size of defect and degree of shunt. Common complications include- pulmonary hypertension, cardiomegaly, atrial dysrhythmia and right sided heart failure. Reference Richard N. Fogoros, M.D. Heart Disease Expert. About health.

Fetal Alcohol Syndrome Essay Example | Topics and Well Written Essays - 2500 words

Fetal Alcohol Syndrome - Essay Example If a woman drinks alcohol during her pregnancy, there are high chances that her baby can be born with FAS, which is a lifelong condition that causes physical and mental disabilities. In today's world where socializing is considered an important part of life, several times women in their reproductive age expose themselves to alcohol. As a consequence, knowingly or unknowingly alcohol abuse is the leading cause of mental retardation in the western world. The amount and timing of alcohol use by the pregnant women determine the type and extent of resulting birth defects. FAS is characterized by Holoprosencephaly which is a condition that is linked with failure of the brain to divide into two hemispheres. This condition is generally associated with neuro-developmental and facial abnormalities. Additionally, there are also possibilities of associated abnormalities of the corpus callosum, the brainstem and the cerebellum, particularly the anterior portion of the vermis. Children with FAS may also suffer due to absence of olfactory lobes, hypoplasia of the hippocampus and abnormal or absent basal ganglia; usually hypoplastic or absent caudate nuclei. According to the results of the positron emission tomography scans, abnormalities is seen in glucose metabolism, especially in the anterior caudate nucleus and the vermis of the cerebellum, even in the absence of overt structural abnormalities (Canadian PaediatricSociety, 2007). There is lack of proper data on the exact prevalence of FAS/atypical FAS. According to studies conducted by Abel (1995), it is estimated that the overall incidence of FAS at 0.97/1000 (0.097%) live births and 43/1000 (4.3%) among babies of heavy drinkers. Based on three population studies, Sampson et al. (1997) estimated the incidence of FAS to be between 2.8/1000 and 4.8/1000 live births, and the incidence of a combination of FAS and ARND to be at least 9.1/1000 live births. In yet another statistic it is said that though all races are vulnerable to FAS, it is excessively higher among American Indian offspring (Aase, 1981). It is also estimated that each year in the United States, 1 in every 750 infants is born with a pattern of physical, developmental, and functional problems is due to fetal alcohol syndrome (FAS), while another 40,000 are born with fetal alcohol effects (FAE) (KidsHealth, 2007). It is important to note that variation in these rates depends on the population studied and the surveillance methods used which may be different for different research groups. In yet another study conducted by CDC show FAS rates ranging from 0.2 to 1.5 per 1,000 live births in different parts of the United States. Besides, other FASDs are thought to occur roughly three times as often as FAS (Centers for Disease Control and Prevention, 2006). Historical Perspective of Fetal Alcohol Syndrome It is interesting to note that concerns have surrounded the consumption of alcohol during pregnancy since biblical times. However, Dr. William Sullivan, a Liverpool prison physician noted higher rates of stillbirth for 120 alcoholic female prisoners than their sober female relatives in 1899. This is the earliest known observation of possible links between maternal alcohol use and fetal damage. He also pointed out that the causal agent was alcohol use (Sullivan, 1899). A case study was conducted by Henry H. Goddard who belonged to one of

StarBurst Technologies Case Study Example | Topics and Well Written Essays - 2500 words

StarBurst Technologies - Case Study Example Quality techniques and quality assessment tools are also suggested in this article. StarBurst Technologies (ST) has their name in the field of technology especially in the market of MP4. Their last product has marketed so well that it provided the required capital for the investment in their new project. That product was Stroll-a device through which all directions to the computer can be given through voice. It was designed to work at the place of mouse. They were going to launch another product which was a mega project too. But this time there are threats to the company's reputation. Their plants in Australia and Asia were not working at per satisfactory level of quality. The rejected Stroll units were running at 43 percent which is enough ratios to effect the reputation of ST. ST is facing problems of bad reputation as well as some quality issues were also faced by some suppliers. Some of the suppliers were found to be not working as per requirement of their job and others need more understanding their job. The above all situations were in the mind of the Operations Director (OD) and he was thinking to resolve these issues. He was satisfied on one aspect of the issue that they have four weeks to set all the issues. 1- ST's suppliers have a number of problems that need fixing. ... 3- There are a number of quality issues highlighted and it is not possible to change all the suppliers, so the only way is to improve how some suppliers work. Provide recommendations for the quality technique a supplier could adopt and why. 4- Having selected the quality technique the need is now to make recommendations on their quality assessment tools that can be used in assessing the issues and problems. 5- State the assumptions made on any aspect of the article. The main problem described in the report is the working behavior of suppliers of the company. It is the fact that it is hard to change the all supplier structure. Rather there should be a planned, well define guideline for system of work of the suppliers to be followed. One to One Market Strategy It is an approach more than a sales approach. It is also called one component, one supplier, one market strategy. It means to identify the customers' needs and then provide the services to one customer at a time. Clearly one supplier will deal with one customer at a moment of time. This strategy aims to recognize the customers' requirements, their complaints and issues on which they want the company to improve its services or products. The basic concept behind this strategy is to concentrate on the customers rather than products or services. It is strongly recommended to identify the company's customers. In customer identification, usually two types of customers are found: 1- A customer who switches to any other company in seek of bargain. 2- A customer who does not switch to any other company rather wants to get a product meeting his/her requirements from the same

McBride Financial Services Governance Evaluation Essay

McBride Financial Services Governance Evaluation - Essay Example The organization is experiencing many challenges at the initial stage since it is a private and small firm. The chief executive officer, Mr. Hugh, is one of the key impediments to the accomplishment of the firm objective, since he is the proprietor of the firm and, as a result, there is a tendency of putting his own interests first. McBride being the chairman of the board and a chief executive officer will have a considerable manipulation of the decision made by the board of directors as well as the management team (Maimako, 2010). This is because being the head of the two organs he can object to a decision that is unfavorable to his own interest. Commercial analysts have criticized the organization for its inability to comply with the rules of investment and borrowing funds from beltway investment. Beltway investment emphasizes that all the firms that seek any assistance from it must comply with all the requirements of investment, failure to which the application of the assistance w ill be null and void. The management of McBride investment is willing to obey and follow all the requirements of Beltway Investments. The management strategy of beltway investment seems to have some doubtful professional standards though McBride seriously opposes the perception. Beltway investment grants firm the freedom to manage their own style. It emphasizes the universal standards of corporate governance and any equity-based compensation plans in line with the achievement of the firm’s objectives. There should be no any form of discrimination. Even though McBride is seeking to fully comply with beltway investment he insists that his decision on the directors and the management method are to be followed. He further insinuates that the firm will manage their finances in their own way to meet the firm’s objectives. McBride financial services will not entertain interference in its affairs. They think that external entities will jeopardize the firm’s operations a nd thwart the achievement of the set goals, (Tricker, 2009). Challenges of McBride financial services MacBride financial services have many challenges since it is a new firm as well as the brokerage firm. In line with corporate governance, the firm has to comply with the international standards where best practices and the formal laws are to be observed. In a nutshell, the problems of the firm are natural since the management organ of the firm has adopted practices that are not within the global standards of corporate governance. McBride financial services are faced with the problem of personnel recruitment. The organization depends on personnel appointed by McBride. These appointments are of doubtful standards since they are based on personal relationships instead of professional qualifications. The decisions to be made by the management organs are so critical and the people to be employed are supposed to be of immense integrity. This means they should undergo a thorough recruitmen t process to get the best. The policy of Mr. Hugh on appointment is that he appoints individuals who go by what he says, and does what he expects of them. This might not work well for the firm's strategic objectives. In the event that the firm experiences by the administrative problem, it will be extremely difficult for them to solve them internally. (Hirschey, & Makhija, 2004).

The controlling of liquid level is essential in most industrial processes such as: food processing, nuclear power plants, water purification systems, industrial chemical processing, boilers etc. Although, most industrial problems such as: controlling the speed of motor, or fluid level in a tank, or temperature of the furnace are due to the installation of control process when the control concepts had not been properly understood (Dutton et al., 1997). However, the ingenuity of control engineer can often overcome these challenges by producing a well-behaved piece of equipment. Mostly, proportional-integral-derivative (PID) controllers are used for liquid level control in most applications and can be applied to many industrial processes and mechanical systems. PID controllers proven to be a perfect controller for simple and linear processes, but when it comes to controlling of non-linear and multivariable processes, the controller parameters have to be continuously adjusted (Bhuvaneswari et al., 2008). In process control systems, nonlinearity is the rule rather than the exception. Most control loops such as pressure, temperature, composition, etc., are significantly nonlinear. This may be because of nonlinearity due to control valves, or on account of variations in process gain, time constant, and dead time, as discussed in (McMillan et al, 1994). Therefore, the study of control system has contributed to huge impact positively to our modern day development. A plant can be controlled manually or automatically and the control system consists of a plant with its actuators, sensors and a controller. Manual controlling process of a plant cannot be as accurately enough compared to automatic control. An automatic controller is made up of device, electronic circuit, computer, or mechanical linkage etc. The interface between the plant and the controller requires actuators (control elements) to provide control action. In instrumentation, detectors and sensors (measurement elements) are needed to provide information about the plant status to the controller (Golten and Verwer, 1991). However, the most important characteristic of a plant is its stability, which indicates that a system can be control smoothly without undue oscillation or overcorrection. The behaviour and performance of a control system depends on the interaction of the entire element. The difference between the set-point and the actual value of the variable is called error. Another important characteristic of a control system is how quickly it can respond to an error and correct it. The smaller the error, the better it would be for the control system. The basic types of process control are open loop and closed loop system. + The open loop system has no feedback because it has no sensor to sense the fluid level in the tank. While the closed loop system is characterised by a sensor and a feedback signal which carries information from the measurement device to the comparator. Typical actuators used in liquid level control systems include pumps, motorised valve, on-off valves, etc. In addition, level sensors such as displacement float, capacitance probe, pressure sensor (Bateson, 1999), etc., provide liquid level measurement for the purpose of feedback control. In a closed loop feedback control system, the forward path transfer function is G(s) representing the process or plant being controlled together with any controller dynamics. The feedback path transfer function, H(s), represents the measurement system or transducer which provides the feedback signal (Golten and Verwer, 1991). The overall transfer function relating the controlled variable Qo to the desired value or reference, Qi is Qi Qo Figure 1: Closed loop block diagram Hence, the procedure of deriving the equation above can be found in the appendix page. In addition, the prime objective of feedback control systems is to minimise the differences between the output and the reference input since this represents the error. The control system should be quick as possible in reducing this error to zero (or to some reasonable low value) when there is either a disturbance or change in reference value (Golten and Verwer, 1991). Feedback has similar advantages when applied to automatic control system, it has the ability of controlling a system that deals with unexpected disturbances that might occur within the system and adapt to changes in the plant. Therefore, with the advancement of electronics and its applications, the understanding of close loop control system increased rapidly, since feedback amplifier is essential (Healey, 1975). A simple control system is used to maintain a constant water level in a tank, example of such is toilet systems in various homes. The swinging arm attached to the input valve of the WC water tank allows water to flow into the tank until the float rises to a point that closes the valve. When the water level is low in the tank, the swinging arm moves downwards which allows more water to flow into the tank. This continues until the swinging arm returns to its initial state. This is a simple and effective level control system for water tank. Another level of control system is a steam boiler where the level of the water in the boiler must be maintained between certain limits; otherwise, it may lead to serious damage to the boiler and building as well as cause hazard to the building occupants (Miller et al, 2004). Water gages serves as a means of measurement level in the boiler. In an engineering context, the addition of control systems must be justified in terms of their profitability, or environment safety. A control system must be effective and efficient, and remain so throughout the life of the plant (Dutton et al., 1997). The performance of a system is often expressed in terms of their parameters such as: speed of response, stability and steady-state error. A good speed of response may often be achieved at the expense of steady state error and stability (Premier, 2008)  [1]  . Stability is one of the most important characteristics in any system. For a system to be stable, the system components must be appropriatel y sized for the application and the system must be correctly adjusted (tuned). The objectives of this project is to investigate the control of water level in non-linear water tank which is fed by a centrifugal pump and discharges to a sump tank through a valve. The tank is a V shaped tank which has a straight wall. The system inflow would be adjusted alongside with the control signal to the outlet valve and the outlet pump during the simulation. Furthermore, the project task includes designing a proportional (P) only and proportional + integral (PI) controller for a specific operating point and implementing it as an analogue s-domain system. The objectives would be accomplished by examining the dynamics of the water tank, modelling it from first principles and by applying step tests to identify the system model at various operating points. The diagram below shows the equipment used to carry out the experiment. Figure 2: Water tank level control system Figure 4: Block diagram of V Shaped Tank system AIM To characterise a new V tank Conduct identification and control experimentation Comparing it with an existing replicate system OBJECTIVE Relating level control to industrial applications. Understanding the dynamics of water tank, modelling it from first principle Application of step-test to identify the system model at various operating points. Designing a proportional + integral controller for specific operating point. 1.1 EXPERIMENT COMPONENTS In order to perform the laboratory experiment on process plant (V-tank), the experimental components used are: amplifier, sensor transducer, water tank, valve, and pump which are discussed below. 1.1.1 AMPLIFIER The amplifier is a very important part of any control system. Basically, it is used to deliver an output signal which is larger, in a prescribed way, than the input signal. A good designed amplifier mostly requires that the input impedance should be large so that the source is not loaded, and the output impedance should be small so that the power element can be easily driven (Anand Zmood, 1995)  [2]  . An amplifier could be referred to as the signal conditioner use in this experiment. An am In pulse width modulation (PWM) the amplitude and repetition rate remain constant, and the width of the pulse is varied according to the modulation signal amplitude (Parr, 1996)  [3]   Pulse Width Modulated (PWM) signals are increasingly being used to drive continuous actuators such as d.c. motor, hydraulic servos and a.c. motor. If the switching frequency of the PWM amplifier is sufficiently high in relation to the actuator time constants, then the signals will be average around the value (Olsson Piani, 1992)  [4]  . The motor is driven by a Pulse Width Modulated (PWM) power amplifier, which supplies power to the motor proportional to a voltage signal from the controller. Pulses are produces at regular intervals, the duration or width of the pulse being proportional to the size of the voltage at each of the times concerned (Bolton, 1991)  [5]  . The reason why pulse width modulation is used is that conventional power amplifiers would simply burn at high power levels. The advantage of switching is that the solid-state devices are not continuously loaded with high power and therefore their power dissipation is low. This fact makes PWM amplifier very efficient. In PWM amplifier, the switching can be directly controlled from the digital output ports of a computer. 1.1.2 SENSOR In virtually every engineering application, there is the need to measure some physical quantities, such as displacements, speeds, forces, pressures, temperatures, stresses, flows and so on. These measurements are performed using this physical device called sensors, which are capable of converting a physical quantity to a more readily manipulated electrical quantity (Onwubolu, 2005). A sensor could be referred to as transducer. Although, there are different kinds of liquid level transducers which are used in variety of control applications with different function such as: float-type liquid level transducers, hydrostatic pressure liquid level transducers, capacitance probes, and so on. But with respect to this project, the pressure transducer will be the point of focus. The pressure transducer is used to measure the height (or head) level in the tank For a sensor to function effectively there is a need for signal conditioner and a display system. This signal conditional obtains signal from the sensor and manipulates it into a condition which are suitable either for display, or control system usefulness. Hence, a display system shows the output readings from the signal conditional (Bolton, 1999)  [6]  . Since the dynamic and static characteristics of the sensor or measuring element affect the indication of the actual value of the output variable, then the sensor plays an important role in determining the overall performance of the control system. The sensor usually determines the transfer function in the feedback path. If the time constants of a sensor are negligibly small compared with other time constants of the control system, the transfer function of the sensor simply becomes constant (Ogata, K., 1997). In selecting a good transducer with respect to its performance and system measurement, certain criteria had to be fulfilled. The accuracy of the transducer to which it has been calibrated, its response to error within the system, its stability i.e. the ability of the transducer to give the same output reading when used to measure a constant input over a period of time, etc (Bolton, 2008)  [7]  . 1.1.3 WATER TANK Water tank is a The tank characteristics are non linear depending on the operating point and are such that tank level surface is a function of the level. Figure 5: Tank fluid level system The objective of the controller in the level control process is to maintain a level set point at a given value and be able to accept new set point values dynamically and this level control system must be controlled by the proper controller. In considering the top section of the tank as shown in fig. 5 above, the flow-rate can be calculated using Bernoullis equation. From Bernoullis law the flow through a valve q (m3s-1) is related to the pressure head across the valve h (m) by the following equation, in which g is the acceleration due to gravity, Cd is the coefficient of discharge (m2) (Dutton et al., 1997). Modelling the Tank The tank can be modelled from first principles with the provision of certain assumptions. For the sake of simplicity, it is possible to consider the top section of the tank with parallel sides and then extend this model to deal with the whole tank. The prismatic section of the tank can be considered to be a simple rectangular tank with an inflow Q and an outflow, QL as in Figure 2. By considering conservation of matter, we can say that the flow into the tank must be equal to the flow out plus the flow converted into a change in level. but if then 1.1.4 VALVE Control valves are commonly encountered elements in process plant and the equation that describes their flow behaviour are nonlinear. Other nonlinear effects may exist because of the valve characteristic and the equipment surrounding the value. Control valves are used to regulate the flow rate of fluid in a system. The control of flow rate can be achieved by varying the size of the passage through which the fluid flows (Stenerson, 2004)  [8]  . The control valve modulates the flow of a fluid by introducing a variable area aperture into the pipeline. The volumetric flow rate, Q, of a particular liquid through a valve is proportional to the pressure drop across it, à ¢Ã‹â€ Ã¢â‚¬  P. Thus, let kv be the valve coefficient which is the function of the valve opening or lift, h. in order to avoid dimensionality, the lift, h is defined as a fractional lift, i.e. when h is 1 the control valve is fully open, and when the h is 0 the value is shut. 1.1.5 VANE PUMP In selecting a pump for a specific task, there are certain factors that needs to be considered such as: the height at which the pump will be moving the liquid to, the speed that is required, and the pressure flow at the pumps outlet. A pump is a mechanical device that changes mechanical power into fluid power. Positive displacement (PD) pumps perform work by expanding and then compressing a cavity, space, or moveable boundary within the pump. In most cases, these pumps actually captured the liquid and transport it through the pump to the discharge nozzle (Bachus Custodio, 2003)  [9]  . However, the flow through PD pump is mostly a function of the speed of the driver or motor. A D.C motor drives the pump at a constant speed in most cases so that the delivery would be constant, i.e. the flow Q is normally constant (Healey, 1975). The pressure or head that a PD pump can generate is mostly a function of the thickness of the casing and strength of the associated accompanying parts (seals, hoses gaskets). In addition, a PD pump has been designed to have some strict tolerance parts. This strict tolerance controls the flow, and pressure that these pumps can generate. The ability to pressurize the fluid to higher pressures will depend on the tolerance of the components within the pump. Hence, the closer the pumps tolerance, the higher the capabilities would be (Brumbach Clade, 2003).  [10]  Furthermore, there are three types of positive displacement pumps in use nowadays which are: vane pump, gear pump and the piston pump. These kinds of pump had different similarities depending on their performance but based on this task it would be concentrated on vane pump. Vane pump are used in hydraulic systems. When the rotor rotates the pumps vanes in a counter clockwise direction which caused the vanes to slide in and out of their slots within the pump housing, a large amount of fluid would be carried from the inlet to the outlet (Onwubolu, 2005)  [11]  . This results from the eccentricity of the centre of the rotor with respect to that of the housing. Figure 3: Vane Pump 1.1.5.1 PUMP TEST In order to examine the pumps accuracy, a test was carried out on the pump. The pump was used to move water from one container to the other within a time limit. Using the laboratory scale machine, the empty container was measured to weighs 0.585Kg. However, the pump was tested at different voltage supplied to the pump from 1v 10v at every one minute and then measured the filled container to know the actual weight. The reading was measured in kilogram (kg) which was converted to litres per minute. The conversion was 1kg to 1litre at a constant time. The outcome of the pump testing experiment could be seen in the graph below. Graph 1: Outcome of Pump Testing Graph In addition, the pump testing results obtained from the graph above shows that the pump was not functioning perfectly. The inaccuracy of the pumps efficiency is as a result of imbalance modified vanes inside the pump. The actual dimension of the vane inside the pump was 8mm inner diameter, 52mm outside diameter and 22mm thickness. The out diameter of the vane was cut-down or modified to roughly about 40mm for the vane to rotate easily within the casing. Hence, the graphs shape should be linear and not the linear curve shape in graph 1. From this experiment, it was observed that at any increase in voltage supplied to the pump; there will be large amount of pressure increase from the flow outlet and vice versa. Pump Figure 4: Modified Vane Size Figure 5: Actual Vane Size 2. LITERATURE REVIEW Literature review 3. CONTROLLER A controller is a device which monitors and influences the operational condition of a given dynamical system. In closed loop control system, a controller is used to compare the output of a system with the required condition and convert the error into a control action designed to reduce error. The error might be as a result of some changes in the conditions being controlled or because of changes in the set value. Most industrial controllers use electricity or pressurized fluid such as oil or air as power sources. Controllers may also be classified according to the kind of power employed in their operation, such as pneumatic controllers, hydraulic controllers, or electronic controllers. For this kind of controllers to be used for a particular task, it must be based on the nature of the plant and the operating conditions (Ogata, K., 1997)  [12]  . 3.1 P ONLY With proportional control the change in the controller output from the set point value is proportional to the error (Bolton, 1991)  [13]  . This means that the correction of the control element such as valve will receive signal which depends on the size of the correction required. Although, a system with a proportional control may have a steady state offset (or drop) in response to a constant reference input and may not be entirely capable of rejecting a constant disturbance (Mutambara, 1999). For higher order systems, large values of the proportional feedback gain will typically lead to instability. For most systems there is an upper limit on the proportional feedback gain in order to achieve a well damped stable response, and this limit may still have an unacceptable steady state error. Therefore, there is a limit on how much the errors can be reduced by using proportional feedback only. One of the ways to improve the steady state accuracy of the control system is to introduce integral control. Set point Error Process variable Amplifier Actuator signal Plant 3.2 P+I CONTROLLER The primary reason for integral control is to reduce or eliminate constant steady state errors within the plant or system. Several limitations of proportional control are resolved by integral control. The steady state response to this class of load disturbance is completely eliminated. Thus, as long as the system remains stable, the system output equals the desired output regardless of the value of KP and its dynamic response (Mutambara, 1999)  [14]  . If the designer wishes to increase the dynamic speed of response with large integral gain, then the response of the system becomes very oscillatory. Hence, in order to avoid this oscillatory behaviour of the system then both proportional and integral control should be used at the same time. Set point Error Process variable Amplifier Actuator signal 3.3 PID CONTROLLER Most industrial processes are controlled using proportional-integral-derivative (PID) controllers. The popularity of PID controllers can be attributed to their good performance in wide range of operating conditions and partly to their functional simplicity, which make it easy to operate (Dorf and Bishop, 2005)  [15]  . PID controllers are so effective that its controlling ability are standard in processing industries such as petroleum, refining, etc. In order to design a particular control loop system, the constants value of KP, KI and KD had to be adjusted to an acceptable performance. Increasing KP and KI tends to reduce system errors but may not be capable of also producing adequate stability, while increasing KD tends to improve stability. The combination of the three control components in this system yields complete control over the system dynamics. The proportional-integral-derivation (PID) controller provides both an acceptable degree of error reduction and an acceptable stability and damping. 4. METHODOLOGY 4.1 STEP-TEST EXPERIMENT The first part of the laboratory experiment involves determining the theoretical model at various level (h) of the water tank which include the prismatic bottom of the tank, the V shaped section and the top parallel sides of the tank. The water level in the tank was measured by a pressure sensor which was calibrated in the instrumentation laboratory prior to the experiment which showed that the pressure transducer produced a voltage signal proportional to the head. To start this experiment, the centrifugal pump was switched on and the Lab View step input programme was opened. The centrifugal pump was used to fill the water tank from a rectangular sump tank and also ensuring that there was enough water in the sump tank to perform the experiment. Although, the control valve was ensured to be fully open so that there would be continuous flow of water from the sump tank into the main tank as a result of constant running of the pump. After warming up the pump for some time, the pump bias was then set on the Lab View program to 1.3 volts (constantly) were the water is just about to start dropping into the tank. Using one second sampling time, the step volt was increased repeatedly by an additional 0.1 volts each time the head (h) settles from 0v 0.1v, 0.1v 0.2v, and so on. As a result of increases in voltage, the water level would be increased as well in the tank. Once the water level reached the top of the tank, in order to prevent the water from overflowing the step volt was reduced back to zero volt (0v) which allows the water to be empty back into the sump tank from the main tank and data or result was collected from the PC. 4.2 P ONLY EXPERIMENT In order to perform the P only experiment, the proportional gain has to be calculated to get the accurate value that would be input into the system. The proportional gain value can then be input into the LabVIEW package to run the experiment. The set point can be changed form one point to another to see how the plant would responds to the sudden changes to increase in set point The second part of the experiment entailed the design of the P only controller and P + I controller. As regards to the P only controller, once the values of the steady state gain and time constant were found from the initial step input experiment, the next step was to design a P only controller which will give closed loop dynamics 1/3 that of the open loop plant, which was then used to calculate the values of Kp at known head (h). Having calculated the Kp values, the pump was then switched on and allowed to warm up, also the Lab View P only controller programme was initiated. With the pump warmed up the Kp value was then entered into the P only controller programme alongside the same value for the pump bias and the sample time used in the previous experiment, i.e. 1.28 volts and 1 seconds respectively. The P only controller programme was allowed to run and the results for the sensor output (volts), the error (e) and the control effort were recorded and retrieved. 4.3 P+I EXPERIMENT Finally to control the level of water in the tank and eliminate the steady state error the Proportional Integral Controller experiment was initiated, the hf (design level to which the tank is to be controlled) was defined and further derivation resulted in two unknowns, Kp and TI. The values for Kp and TI were then calculated for, then input into the Proportional Integral Controller program and allowed to run with a sample time of 1 seconds. The results for the sensor output (volts), the error (e) and the controller output were recorded and retrieved. 5.

History of Nazi Germany :: World War II History

History of Nazi Germany National Socialism between 1920 and 1945 can best be described as an era of constant change. Hitler's enrollment in the German Worker's Party provided him the foundation needed to propel his idealistic views of anti-Semitism and Aryan superiority. Soon after Hitler's enrollment the party's name was changed to the National Socialist German Worker's Party and in the summer of 1921 his talents as an orator and propagandist enabled him to take over the leadership of the Nazi Party. Hitler's initial following - stemmed from German hyper-inflation and devaluation of the mark - included unemployed workers and the lower class, his keen ability to organize rallies to hear his speeches were instrumental in raising monies for the Nazi Party. Although the majority of his followers shared his dislike of the Weimar Republic's liberal democracy and anti-Semitic agenda, his party support, due to it's small size, was limited to the Bavarian region of German, this would prove to be a limiting factor w hen Hitler attempted to seize control of the provincial Bavarian government during his Beer Hall Putsch in November 1923. Hitler's ill-fated attempt of treason proved to work to his advantage; thus, giving him national status as a patriot and a hero in the eyes of many. As a result, Hitler served 9 months in prison for the Beer Hall Putsch and wrote a book titled Mein Kampf (My Struggle) outlining his vision for the future Germany. By late 1924 Hitler was release on parole, after serving a portion his five year sentence, and quickly regained control of the Nazi Party, noting that any future seizure must come by legal measures through Parliamentary elections. Faced with a temporary improvement of the German economy by the Weimar Republic's ability to secure loans and investments (mostly from America), Hitler was forced to wait until economic conditions worsened to propel his Nazi agenda. In 1929 Hitler finally got his chance, the American stock market crash of 1929 affected nearly every nation in the world and German prosperity soon came to an end as a result of the Great Depression, vast unemployment and hunger that followed. President Hindenburg's Weimar Republic soon found itself obligated to repay debts owed to countries that once provided assistance during times of prosperity. Discontented German people wanted change and Bruening (Chancellor) believed that a stable parliament majority for his party could deliver the change required, so new elections were held.
