The History Plays of Shakespeare Essay - 1900 Words
The term History Play is commonly used to denote the plays (whether tragedies or comedies) in which the action and the major themes of the play are primarily political rather than individual or social. Though Shakespeare did not distinguish between the genres of his plays, when the collected works of Shakespeare was published by his own colleagues in the Chamberlains- Kings company as the First Folio in 1623, the plays, the editors divided them into Comedies, Histories and Tragedies. Though some historical plays show the characteristics of tragedy or comedy, they are different from the regular tragedies and comedies in that they deal only with political matters without straying into other social or metaphysical matters. Thus onlyâ⬠¦show more contentâ⬠¦He often distorted chronology and events were condensed. But all these changes were aimed at an effective presentation for the stage and for a sense of veracity. Instead of a mere reproduction of facts, Shakespeare aimed in his history plays to represent a realistic picture of the past. The ten history plays of Shakespeare were divided into two groups of four plays each (the tetralogies) and two single plays unrelated to either group. The First History Cycle written in the early days of Shakespeares career consists of the three parts of Henry VI and Richard III. The Second History Cycle consisted of Richard II, Henry IV-Part 1, Henry IV Part 2 and Henry VI and was written late in his career. The two unrelated plays were King John and Henry VIII. Shakespeare wrote the two four-play sequences dealing with the full story of the Wars of the Roses. The minor tetralogy or the First History Cycle consisted of the three Henry VI plays and Richard III and dealt with the years between 1422 and 1485, from the death of Henry V to the deformed prince Richard III. The First History Cycle, written when Shakespeare was in his twenties lacked the dramatic structure of the Second History Cycle, therefore called the minor tetralogy.

Lean Six Sigma Principles On Improving Turnaround Times At...
Researchers Lamm, Eckel, and Amerine desired to explore the effectiveness of Lean Six Sigma principles on improving turnaround times at a busy U.S. infusion clinic. The team implemented a three-phase study in which they first analyzed turnaround times for a period of 12 months. Next, they implemented several Lean tools including a five-day Kaizen event to identify potential ways to reduce turn around times from 60 to the new goal of 45 minutes. During the last phase the researches implemented strategies identified during the Kaizen event. The study revealed positive results!

However, the researchers noted that sometimes changes where implemented without sufficient statistical evidence to support the change. Yet in other cases some statistical findings were over exaggerated. Therefore, they advise that care should be taken to determine the practicality of changes. This study provides the reader with enough evidence to support the use of Six Sigma in healthcare while highlighting some of the potential pitfalls of the methodology. The purpose of this study was to develop long-term solutions targeted at improving care outcomes in a high-risk Neurotrauma Intensive Care Unit (NTICU). The authors utilized Six Sigma strategies, specifically Define-Measure-Analyze-Control (DMAIC), to reduce central line use and curb central line-associated bloodstream infections (CLASBI). The driving factors for the study are increasing pressures from the Institute of Medicine and the Joint Commission to reduce hospital-associated infections. Initiatives derived from the use of Six Sigmaââ¬â¢s DMAIC process were responsible for reducing the NTICU CLASBI rate below national benchmarks. Ultimately, these initiatives resulted in a total savings of $204,092 in costs related to avoidable infections.

Existentialism (1344 words) Essay Example For Students
Existentialism (1344 words) Essay ExistentialismExistentialism is a philosophical movement that developed during the 19th and 20th centuries. One of the first things one may notice about existentialism is the confusion and disagreement of what it actually is. This is because those who developed it have conflicting ideas. Walter Kaufmann, one of the leading existential scholars says, Certainly, existentialism is not a school of thought nor reducible to any set of tenets. The three writers who appear invariably on every list of existentialists, Heidegger, and Sartre are not in agreement on essentials. By the time we consider adding Rilke, Kafka, and Camus, it becomes plain that one essential feature shared by all these men is their perfervid individualism. Therefore, a precise definition is impossible; however, it suggests one major theme: a stress on individual existence and the subsequent development of personal essence. Man is the only known being, according to existentialists, that defines itself merely through th e act of living. In other words, first you exist, and then the individual emerges as life decisions are made. Freedom of choice, through which each human being creates their own nature, is one of the basic themes. Because individuals are free to choose their own path, existentialists have argued that they must accept the risk and responsibility of their actions. 2Every person spends a lifetime changing his or her essence. Without life there can be no meaning; the search for meaning in existentialism is the search for self. In other words, we define ourselves by living; killing yourself would indicate you have chosen to have no meaning. Existentialists believe in living in fact fighting for life. Camus, Sartre, and Nietzsche were involved in various wars because they had a strong belief in fighting for the survival of their respective countries. In order to understand the current meaning of existentialism, one must first understand that the American view of existentialism was derived from the writings of political activists, not intellectual purists. Americans learned the term existential after World War II. The term is credited to Jean-Paul Sartre to describe his own philosophies, but it was actually coined by Kierkegaard when he described his existential dialectic. It was not until the late 1950s that the term was applied broadly to several divergent schools of thought. Existentialism maintains that life is a series of choices, creating stress. Few decisions are without any negative consequences. Some things are irrational or absurd, without explanation. If one makes a decision, he or she must follow through. Beyond this short list of concepts, the label existentialist is applied broadly. Even these concepts are not universal within existentialist writings, or at least the writings of people labeled as such. Blaise Pascal, for example, spent the last years of his life writing in support of predetermination, the theory that is better known as fate. 3First, there is the basic existentialist standpoint, that existence precedes essence. Man is a conscious subject, rather than a thing to be predicted or manipulated; he exists as a conscious being, and not in accordance with any definition, essence, generalization, or system. Existentialism says I am nothing but my own conscious existence. A second existentialist theme is that of anxiety, or the sense of anguish, a generalized uneasiness, and a fear or dread that is not directed to any specific object. Anguish is the dread of the emptiness of human existence. This theme is as old as Kierkegaard is within existentialism; it is the claim that anguish is the underlying, all-pervasive, universal condition of human existence. Existentialism agrees with certain ideas in Judaism and Christianity, which see human existence as fallen from grace, and humans have lived in suffering, guilt, and anxiety. This dark and depressing view of human life leads existentialists to reject ideas such as happiness, enlightenment optimism, a sense of well-being, since these can only reflect a superficial understanding of life, or a naive and foolish way of denying the despairing, tragic aspect of human existence. .u12b58e34cbc04cf0951e00ae9e4b7454 , .u12b58e34cbc04cf0951e00ae9e4b7454 .postImageUrl , .u12b58e34cbc04cf0951e00ae9e4b7454 .centered-text-area { min-height: 80px; position: relative; } .u12b58e34cbc04cf0951e00ae9e4b7454 , .u12b58e34cbc04cf0951e00ae9e4b7454:hover , .u12b58e34cbc04cf0951e00ae9e4b7454:visited , .u12b58e34cbc04cf0951e00ae9e4b7454:active { border:0!important; } .u12b58e34cbc04cf0951e00ae9e4b7454 .clearfix:after { content: ""; display: table; clear: both; } .u12b58e34cbc04cf0951e00ae9e4b7454 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u12b58e34cbc04cf0951e00ae9e4b7454:active , .u12b58e34cbc04cf0951e00ae9e4b7454:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u12b58e34cbc04cf0951e00ae9e4b7454 .centered-text-area { width: 100%; position: relative ; } .u12b58e34cbc04cf0951e00ae9e4b7454 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u12b58e34cbc04cf0951e00ae9e4b7454 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u12b58e34cbc04cf0951e00ae9e4b7454 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u12b58e34cbc04cf0951e00ae9e4b7454:hover .ctaButton { background-color: #34495E!important; } .u12b58e34cbc04cf0951e00ae9e4b7454 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u12b58e34cbc04cf0951e00ae9e4b7454 .u12b58e34cbc04cf0951e00ae9e4b7454-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u12b58e34cbc04cf0951e00ae9e4b7454:after { content: ""; display: block; clear: both; } READ: Aldous Huxley wrote Brave New World out of fear of EssayA third existentialist theme is that of absurdity. An existentialist would say I am my own existence, but this existence is absurd. To exist as a human being is inexplicable, and absurd. Each of us is simply here, thrown into this time and placebut why now? Why here? Kierkegaard asked. For no reason, without necessary connection, my life is an absurd fact. 4It is common for people to associate a lack of faith or secular beliefs with existential thought. Existentialism has little to do with faith or the lack thereof. Religion is merely another choice you make in weaving your essence. Existentialism is not a singular school of thought, devoid of any and all forms of faith. It may surprise laypersons that many of the existentialists were religious. Pascal and Kierkegaard were dedicated Christians. Pascal spent the end of his life in a monastery. Kierkegaard was a passionate Protestant, and supporter of Luthers teachings. Despite his famous (infamous?) God is dead quote, Nietzsche also appears to have been a believer in a Creator, though he branded organized religion as a manipulative tool to control the masses. He often insulted the Church merely to cause a stir. Some, notably Walter Kaufmann, call Nietzsche the anti-Christian existentialist, because he believed the organized Christian churches were the most destructive influences of his time. For clarification, Nietzsche did write that the Creator had no influence on humanity, which indicates a deistic view of creation. Nietzsche did not worry about the afterlife. Dostoevsky was Russian-Orthodox, to the point of being fanatical, though evidence shows that he did not live by these morals (he was a bad b oy, if you will). Kafka was Jewish, so he cannot be considered secular, either. His family was not as religious as Kafka himself might have liked, but when you take into consideration that his family died in concentration camps, it is obvious why his father might not have been very public with his faith. Hegel, the German idealist from whose theories many existentialists drew5from, (despite their vehement denials of his work) was very religious. He wrote that all authority must be derived from the divine right. Hegels system of ethics was based on the existence of a supreme creator and this creators will. We are then left with Camus and Sartre, and of these two, only Sartre can be seen to consistently deny any and all belief in a divine creator. Sartre was raised with religion, but World War II and the constant suffering of the world drove him away from faith. Many existentialists believe the greatest victory of the individual is to realize the absurdity of life and to accept it. In short, you live a miserable life, for which you may or may not be rewarded by a greater force. If this force exists, why do men suffer? If it does not exist, why not commit suicide and shorten your suffering? These questions indicate the confusion of existentialism. Personally, I agree with many of the basic tenets of existentialism. Personal accountability for the decisions and actions made seems to be something that is fading from public opinion. Excuses seem to be replacing responsibility. Existentialism is liberating for those of us who do not rely on fate, God, or chance to guide us through the path of life. One aspect that is questionable is our ability to continuously reinvent ourselves through our actions. While this is wholly possible, the vast majority of people stick to old ways of doing things, or follow others blindly. Despite encompassing a staggering range of philosophical, religious, and political ideologies, the underlying concepts of existentialism are simple. Mankind has free will. Life is a series of choices, creating stress. Few decisions are without any negative6consequences. Some things are irrational or absurd, without explanation. If one makes a decision, he or she must follow through. The decisions you make are whom you are, so decide accordingly. .u831dd39ae57eac9e35ecae632234fb8a , .u831dd39ae57eac9e35ecae632234fb8a .postImageUrl , .u831dd39ae57eac9e35ecae632234fb8a .centered-text-area { min-height: 80px; position: relative; } .u831dd39ae57eac9e35ecae632234fb8a , .u831dd39ae57eac9e35ecae632234fb8a:hover , .u831dd39ae57eac9e35ecae632234fb8a:visited , .u831dd39ae57eac9e35ecae632234fb8a:active { border:0!important; } .u831dd39ae57eac9e35ecae632234fb8a .clearfix:after { content: ""; display: table; clear: both; } .u831dd39ae57eac9e35ecae632234fb8a { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u831dd39ae57eac9e35ecae632234fb8a:active , .u831dd39ae57eac9e35ecae632234fb8a:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u831dd39ae57eac9e35ecae632234fb8a .centered-text-area { width: 100%; position: relative ; } .u831dd39ae57eac9e35ecae632234fb8a .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u831dd39ae57eac9e35ecae632234fb8a .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u831dd39ae57eac9e35ecae632234fb8a .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u831dd39ae57eac9e35ecae632234fb8a:hover .ctaButton { background-color: #34495E!important; } .u831dd39ae57eac9e35ecae632234fb8a .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u831dd39ae57eac9e35ecae632234fb8a .u831dd39ae57eac9e35ecae632234fb8a-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u831dd39ae57eac9e35ecae632234fb8a:after { content: ""; display: block; clear: both; } READ: Sexual Harassment in the Workplace EssayBibliographyWorks CitedGrene, Marjorie.

Our next guide discusses really useful pointers on properly writing a deductive essay. Before checking out that guide though, we want you to have a look at a sample essay on one of the topics mentioned above. Sample Deductive Essay: Health and Music. How Does One Affect the Other? Music can be used as a form of therapy to address many health issues. This is not just a hypothesis but rather a proven science which is being applied actively on patients. Heart disease, for example, can be remedied through musical activities. Through these activities, heart rate and pulse can be reduced, the respiratory rate can also be cut down while reducing blood pressure and maintaining it at healthier levels. Overall, all these reductions and improvements across the board considerably help people to effectively deal with coronary heart disease. Although itââ¬â¢s not proven that music can help people with psychological distress, as there is little evidence and the clinical significance is unfeasible, it can definitely improve overall heart health if a patient is listening to the concerto of Mozart or any song from popular music charts, their blood pressure reduces significantly while the heartââ¬â¢s resting rate goes down as well, and so do stress levels. Even in the case of neurological diseases, music can act as therapy and help people fight certain health disorders;à typically, disorders like amnesia, dementia, schizophrenia, mood disorders, Parkinsons disease, aphasia and Tourettes Syndrome all show improvements once the brain is exposed to music. In the case of stroke, music can be effective because it affects certain regions of the brain. music can effect emotions or improve their social interaction skills, which can ultimately be very beneficial to stroke victims. Music therapy can result in decreased depression and anxiety while elevating mood. All school of thoughts come together when it comes to this topic because both descriptive and experimental studies have successfully catalogued and documented various effects of music. These effects include environment awareness, quality of life, expression of feelings, responsiveness, awareness, socialization and positive association. Positive behavioral and social outcomes are caused by music therapy. You can also find some encouraging trends. A program was developed by Dan Cohen called ââ¬Å"The Music and Memory Programâ⬠. This program started when Mr. Cohen was nursing at a home in City Central, New York, where he provided the local residents with iPods. The success of the program led to the Shelley Donald Rubin Foundation which was funding it entirely in 2008. Because of this milestone, Cohen was able to test on a much larger scale. Later in 2010, the Music Memory Program went on to become an official non-profit organization and a documentary was also released called ââ¬Å"Alive Inside: A Story of Music and Memoryâ⬠, which was based on the Music Memory Program. That documentary helped the program gain wider support and awareness, because of a scene in the documentary where an Alzheimers patient miraculously awakes listening to songs of Cab Calloway, which was music from a time he could instantly relate to. After a preview of the documentary, it received a record 11 million views. Thanks to this documentary, it became a fact that there is, apparently, a direct connection between music and health.

Rating Minerals on Mohs Scale of Hardness
Rating Minerals on Mohs Scale of Hardness Mohs hardness scale was devised in 1812 by Friedrich Mohs and has been the same ever since, making it the oldest standard scale in geology. It is also perhaps the most useful single test for identifying andà describing minerals.à You use the Mohs hardness scale by testing an unknown mineral against one of the standard minerals. Whichever one scratches the other is harder, and if both scratch each other they are the same hardness. Understanding Mohs Hardness Scale The Mohs scale of hardness uses half-numbers, but nothing more precise for in-between hardnesses. For instance,à dolomite, which scratches calcite but not fluorite, has a Mohs hardness of 3à ½ or 3.5.à Mohs Hardness Mineral Name Chemical Formula 1 Talc Mg3Si4O10(OH)2 2 Gypsum CaSO4à ·2H2O 3 Calcite CaCO3 4 Fluorite CaF2 5 Apatite Ca5(PO4)3(F,Cl,OH) 6 Feldspar KAlSi3O8 ââ¬â NaAlSi3O8 ââ¬â CaAl2Si2O8 7 Quartz SiO2 8 Topaz Al2SiO4(F,OH)2 9 Corundum Al2O3 10 Diamond C There are a few handy objects that also help in using this scale. A fingernail is 2à ½, a penny (actually, any current U.S. coin) is just under 3, a knife blade is 5à ½, glass is 5à ½Ã and a good steel file is 6à ½.à Common sandpaper uses artificial corundum and is hardness 9; garnet paper is 7à ½. Manyà geologists just use a small kit featuring 9 standardà minerals and some of the above-mentioned objects; with the exception of diamond, all of the minerals on the scale are fairly common and inexpensive.à If you want to avoid the rare chance of a mineral impurity skewing your results (and dont mind spending some extra money), there are sets of hardness picks available specifically for the Mohs scale.à The Mohs scale is an ordinal scale, meaning that it isà not proportional.à In terms of absolute hardness, diamond (Mohs hardness 10) is actually four times harder than corundum (Mohs hardness 9) and six times harder than topaz (Mohs hardness 8).à For a field geologist, the scale works great.à A professional mineralogist or metallurgist, however, might obtain absolute hardness by using aà sclerometer, which microscopically measures the width of a scratch made by a diamond.à Mineral Name Mohs Hardness Absolute Hardness Talc 1 1 Gypsum 2 2 Calcite 3 9 Fluorite 4 21 Apatite 5 48 Feldspar 6 72 Quartz 7 100 Topaz 8 200 Corundum 9 400 Diamond 10 1500 Mohs hardness is just one aspect of identifying minerals. You also need to consider luster, cleavage, crystalline form, color, and rock type to zero in on an exact identification. See this step-by-step guide to mineral identification to learn more. A minerals hardness is a reflection of its molecular structure - the spacing of the various atoms and the strength of the chemical bonds between them. The manufacture of Gorilla Glass used in smartphones, which is nearly hardness 9, is a good example of how this aspect of chemistry is related to hardness. Hardness is also an important consideration in gemstones. Dont rely on the Mohs scale to test rocks; it is strictly for minerals. The hardness of a rock depends on the exact minerals that make it up, particularly the mineral that cements it together. Edited by Brooks Mitchell

Advanced taxation Case Study Example | Topics and Well Written Essays - 2500 words
Advanced taxation - Case Study Example Lord Bolsover is quite wrong in his thinking that in the event of his death,all his belongings will be divided equally between his wife and son.He is also wrong in assuming that the income and assets of the married coupe are added together for tax purposes. The fact that he has not made any will so far will make his successors liable for inheritance tax in the event of his death.Present taxation system charges Inheritance Tax on any estate worth over 300,000 (for Tax year 2007 -2008). The value of estate is arrived at by adding up the value of every thing one owns including the share in jointly owned properties. The amount of large gifts made during the last 7 years before death will also be subjected to inheritance tax.Up to the value of 300,000 the estate is covered under 'nil rate band' and no IH tax is payable. Any value over the 'nil rate band' becomes taxable at a rate of 40 percent. Inheritance tax is to be paid out before the money and belongings of the deceased can be distri buted according to his/her will.Based on the above premise unless some tax planning is not done immediately, Lord Bolsover's estate would be subjected to inheritance tax. The following are some of the ways in which the incidence of Lord Bolsover's estate to inheritance tax could be mitigated.The 'nil rate band' is an effective saving in the value of the estate which would otherwise be subjected to inheritance tax.... Annual Exemption of 3000 which can be carried forward for one tax year, Marriage gifts exemption of 5000 to each of the children, 2500 to each of the grand children and 1000 to anyone (these gifts are exempted subject to the condition that the gift is made before the wedding day) and exemption of small gifts made to anyone up to a value of 250 during the tax year. All these gift exemptions have the effect of reducing the value of the estate that may be subjected to inheritance tax. 1.2 Making Direct Gifts: This is another way of mitigating the incidence of the inheritance tax on the estate of Lord Bolsover. However for using this method of tax avoidance there are two hitches which Lord Bolsover has to consider: He should live at least for 7 years to make the gifts exempt from tax He cannot have access to the monies gifted by him on his own accord. The important point to note here is that any gift made directly or into an absolute trust over and above the exempt gift allowance will be deemed as 'Potentially Exempt Transfers (PET) for a period of 7 years and until this period of 7 years the person making the gifts should remain alive to make the gifts eligible for exemption from inheritance tax. However the law allows the charging of the inheritance tax pro-rata depending on the year of death after the gifts or transfers are made, subject to the nil rate band of 300,000. This method of taxing pro-rata is known as Taper Relief which reduces the tax incidence by 20 percent every year after an initial period of 3 years. That means the reduction of tax rate will start from the fourth year before death onwards. But there are several other considerations like the time at which Lord Bolsover wants the beneficiaries to get the gifts, change in the circumstances of the

Successful Advertising Campaign Assignment Example | Topics and Well Written Essays - 500 words
Successful Advertising Campaign - Assignment Example The adage gained consumerââ¬â¢s liking as something motivational, positive, individualistic, and neutral on the issue of either winning or losing. It is just about doing and people simply love that as a strategic bandwagon technique in marketing. Nike had also topped in television and print broadcast thus gaining massive ground from the market consumers specially those coming from the youth or young adults who are consistent in demonstrating their zeal in life. Reports mentioned that Nike got the sale of $800 million in 1988 and consistently grew a decade later into $ 9.2 billion. ââ¬Å"Just Do It!â⬠drives the people to run, exercise, wind up, and enjoy everything that relates to life. It evokes certain zeal that deconstructed the notion of hindrances, barriers, and possible losses there is in life. The productââ¬â¢s adage, which wrapped its corporate brand, stirred such emotional meaning to consumers and the market. Aside from dominating its presence in all multimedia advertisement centers of the country, Nikeââ¬â¢s consumers became also its marketing advertisers by indirectly introducing the products to those who have not yet purchased it. They recreated the product and thus facilitated in making the product as a youthsââ¬â¢ fashion fad and fashion statement. The company likewise was able to establish the best branding strategy. Carefully planned and genuinely sensitive to the increasing individualism of consumers, the company won the hearts and minds of the market, including the essential fact that they were successfully able to make their own product subscribers as ambassador of a superior product. They completed the leverage by dominating in the market competition. Rigorous advertising and the ability to be consistently visible in the market made the product legendary for purchasers. The brand and its adage became the replica of their lives and an advice for those

Basic Electronics Essay Example for Free
Basic Electronics Essay The p-n junction is a homojunction between a p-type and an n-type semiconductor. It acts as a diode, which can serve in electronics as a rectifier, logic gate, voltage regulator (Zener diode), switching or tuner (varactor diode); and in optoelectronics as a light-emitting diode (LED), laser diode, photodetector, or solar cell. In a relatively simplified view of semiconductor materials, we can envision a semiconductor as having two types of charge carriers-holes and free electrons which travel in opposite directions when the semiconductor is subject to an external electric field, giving rise to a net flow of current in the direction of the electric field. Figure 1 illustrates the concept. A p-n junction consists of a p-type and n-type section of the same semiconductor materials in metallurgical contact. The p-type region has an abundance of holes (majority carriers) and a few mobile electrons (minority carriers); the n-type region has an abundance of mobile electrons and a few holes (Fig. 2). Both charge carriers are in continuous random thermal motion in all directions. Fig. 2. Energy levels and carrier concentrations for a p-type and n-type semiconductor before contact. 1 When a section of p-type material and a section of n-type material are brought in contact to form a pn junction, a number of interesting properties arise. The pn junction forms the basis of the semiconductor diode. Electrons and holes diffuse from areas of high concentration toward areas of low concentration. Thus, electrons diffuse from the n-region to the p-region. , leaving behind positively charged ionized donor atoms. In the p-region the electrons recombine with the abundant holes. Similarly, holes diffuse from the p-region into the n-region, leaving behind negatively charged ionized acceptor atoms. In the n-region the holes recombine with the abundant mobile electrons. This diffusion process does not continue indefinitely, however, because it causes a disruption of the charge balance in the two regions. As a result, a narrow region on both sides of the junction becomes nearly depleted of the mobile charge carriers. This region is called the depletion layer. It contains only the fixed charges (positive ions on the n-side and negative ions on the p-side). The thickness of the depletion layer in each region is inversely proportional to the concentration of dopants in the region. The net effect is that, the depletion region sees a separation of charge, giving rise to an electric field pointing from the n side to the p side. The fixed charges create an electric field in the depletion layer that points from the n-side towards the p-side of the junction. The charge separation therefore causes a contact potential (also known as built-in potential) to exist at the junction. This built-in field obstructs the diffusion of further mobile carriers through the junction region. An equilibrium condition is established that results in a net contact potential difference Vo between the two sides of the depletion layer, with the n-side exhibiting a higher potential than the p-side. This contact potential is typically on the order of a few tenths of a volt and depends on the material (about 0. 5 to 0. 7 V for silicon). The built-in potential provides a lower potential energy for an electron on the n-side relative to the p-side. As a result, the energy bands bend as shown in Fig. 3. In thermal equilibrium there is only a single Fermi function for the entire structure so that the Fermi levels in the p- and the n-regions must align. No net current flows across the junction. The currents associated with the diffusion and built-in field (drift current) cancel for both the electrons and holes. Fig. 3. A p-n junction in the Thermal equilibrium at T gt; 0? K. The depletion-layer, energy-band diagram, and concentrations (on a logarithmic scale) of the mobile electrons n(x) and holes p(x) are shown as a functions of the position x. The built-in potential difference V corresponds to the energy eV where e is the electron charge. 0 0 2 The Biased p-n Junction An externally applied potential will alter the potential difference between the p- and n-regions. This in turn will modify the flow of majority carriers, so that the junction can be used as a ââ¬Å"gateâ⬠. If the junction is forward biased by applying a positive voltage V to the p-region (Fig. 4), its potential is increased with respect to the n-region, so that an electric field is produced in a direction opposite to that of the built-in field. The presence of the external bias voltage causes a departure from equilibrium and a misalignment of the Fermi levels in the p- and n-regions, as well as in the depletion layer. The presence of the two Fermi levels in the depletion layer, Efc and Efv represents a state of quasi-equilibrium. Fig. 4. Energy band diagram and carrier concentrations for a forward-biased p-n junction. In effect, then, if one were to connect the two terminals of the p-n junction to form a closed circuit, two currents would be present. First, a small current, called reverse saturation current, is, exists because of the presence of the contact potential and the associated electric field. In addition, it also happens that holes and free electrons with sufficient thermal energy can cross the junction. This current across the junction flows opposite to the reverse saturation current and is called diffusion current. Of course, if a hole from the p side enters, it is quite likely that it will quickly recombine with one of the n-type carriers on the n side. (Fig. 4) The net effect of the forward bias is to reduce the height of the potential-energy hill by an amount eV. The majority carrier current turns out to increase by an exponential factor exp(eV/kT). So that the net current becomes i = isexp(eV/kT) ââ¬â is, where is is nearly a constant. The excess majority carrier holes and electrons that enter the n and p regions, respectively, become minority carriers and recombine with the local majority carriers. To explain the mechanism of reverse conduction, one needs to visualize the phenomenon of avalanche breakdown. When a very large negative bias is applied to the p-n junction, sufficient energy is imparted to charge carriers that reverse current can flow, well beyond the normal reverse, saturation current. In addition, because of the large electric field, electrons are energized to such levels that if they collide with other charge carriers at a lower energy level, some of their energy is transferred to the carriers with low energy, 4 and these can now contribute to the reverse conduction process, as well. This process is called impact ionization. Now, these new carriers may also have enough energy to energize other lowenergy electrons by impact ionization, so that once a sufficiently high reverse bias is provided, this process of conduction takes place very much like an avalanche: a single electron can ionize several others. Fig. 6. The reverse breakdown region The phenomenon of Zener breakdown is related to avalanche breakdown. It is usually achieved by means of heavily doped regions in the neighbourhood of the metal-semiconductor junction (the ohmic contact) . The high density of charge carriers provides the means for a substantial reverse breakdown current to be sustained at a much lower specific voltage than normal diode, at a nearly constant reverse bias known as the Zener voltage, Vz. This phenomenon is very useful in applications where one would like to hold some load voltage constant for example, in voltage regulators. The response time of a p-n junction to a dynamic (ac) applied voltage is determined by solving the set of differential equations governing the processes of electrons and hole diffusion, drift (under the influence of the built-in and external electric fields), and recombination. These effects are important for determining the speed at which the diode can be operated. They may be conveniently modeled by two capacitances, a junction capacitance and diffusion capacitance, in parallel with an ideal diode. The junction capacitance for the time necessary to change the fixed positive and negative charges stored in the depletion layer when the applied voltage changes. The thickness l of the depletion layer turns out to be proportional to v(Vo-V); it therefore increases under the reverse-bias conditions (negative V) and decreases under the forward-bias conditions (positive V). The junction capacitance C=?A/l (where A is the area of the junction) is therefore inversely proportional to v(VoV). The junction capacitance of a reverse-biased diode is smaller (and the RC response time is therefore shorter) than that of a forward-biased diode. The dependence of C on V is used to make voltage-variable capacitors (varactors). 5 Experiment l(a) : i-v characteristics of a semiconductor diode Procedure Connect the diode according to the circuit diagram as shown in Fig. 8. Fig 8 Vary the voltage V on the power supply between 0-30V. Alternately, the second concept is that the blocking action of an inductor stops the a. c. portion while the d. c. portion passes without much attenuation. Note: For filtering, large capacitance (hundreds to tens of hundreds microfarad) is needed. These are generally electrolytic capacitors, which consist of a repeating sandwich of aluminum sheets and a conducting paste, rolled into a cylinder for miminmun size. The aluminum sheets are polarized to form thin layers of aluminum oxide, a dielectric insulating material. The thinner the the dielectric the higher the capacitance will be.

Dbq- Scientific Revolution
DBQ ââ¬â The Scientific Revolution The Scientific Revolution of the sixteen and seventeenth century were affected greatly from the contributions of the opposing voice and ideas of the Church and their disagreement with the uprising of scientific studies. Despite the rejection from the Church, the Scientific Revolution was heavily influenced by those in society who felt differently, and believed the benefits the Scientific Revolution would bring. This view however, was unequally agreed in when it came to the view of it politically.Still during the sixteenth and seventeenth century, religious and the Church played a great role in the ways of people. Till the time of the Scientific Revolution, many things were not questioned, but once scientists began to question the traditional beliefs, many people of the church were outraged and spoke openly against it. Even people like Copernicus, who was the great contributor to the heliocentric idea, denied himself and submitted to the church e ven dedicating a part of his book to Pope III which showed his fear and actions in pleasing the pope to avoid condemnation. doc. 1) His situation greatly exemplified how the Scientific Revolution although was growing but many times stunted because of fear from the disapproval from the Church. Italian monk Giovanni Ciampoli also expressed his disapproval in a letter to Galileo stating with much urgency that the nature of the world should just be left alone for the Scripture to explain it and that man should not go about their ways to reason why. (doc. 3) Similar to Copernicus, Walter Charleton a English doctor and natural philosopher who studied the balance of science and religious.He makes it clear that science is only possible with religion. Although he does not completely push the idea of scientific studies, he does believe it is only possible with the power of God. (doc. 8) The conclusion as you interpret out of Charleton is that no matter what man upholds through science or idea s are not sufficient enough to differ or oppose what God determines it to be. The views of secular people and society also bought about significant influence upon the Scientific Revolution, but just on the other side of the scale.Francis Bacon, a English philosopher of science made it evident in his advocacy of science. In fact, in the document, he expresses his eagerness of the goal people need to bring achievement in human society. (doc. 4) The document shows that despite the lack of support from the church was given, many people chose to stray away tradition and venture out into new ideas. Another document that poses the same suggestion as Bacon as to improving the community of scientific studies was that of Henry Oldenbury, Secretary of the English Royal Society in his letter to Johannes Hevelius.Oldenbury emphasizes the need in cooperation, and that scientists shouldnââ¬â¢t just focus on oneââ¬â¢s study, put into consideration with the studies of others to develop the edu cation of science. (doc. 6) Oldenbury in saying ââ¬Å"friendship among learned men is a great aid to the investigation and elucidation of the truthâ⬠only shows him hinting that a society of scientist should be raised. Both Bacon and Oldenbury were men during the seventeenth century who viewed science as a way to improve and enhance society, but others had a different view.Margaret Cavendishââ¬â¢s Observations on Experimental, shows her demand in questioning why women were not allowed to be a part of the revolution and contribute as men could, and her willingness in building upon the study of natural philosophy of women if she were allowed. (doc. 9) Her partake showââ¬â¢s that the influences of the Scientific Revolution did not solely come from different men of different social communities, but it had even spread to the other gender, which shows involvement. Political figures serve as a voice and power of the people in their society. In this case, politics took a great p art in the uprise of the Scientific Revolution.Document 5 is a letter from French monk Marin Mersenne to his noble patron in which he asks for the approval of his patron on his statements based on his experiments. His letter expresses a sense of meekness and humbleness Mersenne has for his patrons. He feels pressure in doing things correctly for his patrons, and is hindered from sharing what he has experimented on without winning the approval from his patrons. The power of political figures still remained throughout the sixteenth and seventeenth century, which from this document, shows how some studies were hindered because of the political authority.Political influences on scientific studies included personal beliefs on how scientific research should be controlled and suppressed. Thomas Hobbes, an English philosopher believed that any scientific findings that would interfere with the authority of rulers should be rid of. (doc. 7) Hobbes, a strong believer in an absolute monarch emp hasized the power of rulers to overpower the research of scientists. Unlike other documents, the depiction of the drawing that commemorated Louis XIVââ¬â¢s visit to the French Royal Academy, although not a very reliable source still portrayed how Louis XIVââ¬â¢s support in the scientific studies.Since a ruler takes up such a huge part in a country, the people of the country, in this case France, would naturally follow in the steps of their ruler. Louis XIV from this painting wouldââ¬â¢ve initiated a message that showed The work of scientists were affected by religious, social, and political ideas and influences in the sixteenth and seventeenth century. All these affected in ways that encouraged the study of science, while others felt that all scientific research should be stopped and suppressed.

Using French Verbs with Prepositions
In English, many verbs require a certain preposition in order for the meaning of the verb to be complete, such as to look at, to take care of, etc. The same is true in French, but unfortunately, the prepositions required for French verbs are often not the same as the ones required by their English counterparts. In addition, some verbs that require a preposition in English dont take one in French, and vice versa. Deà andà à à are by far the most common French prepositions for verbs. Because there are so many, these are divided into those that are followed by an infinitive and those that are followed by an indirect object. à à infinitiveà à indirect objectdeà infinitivedeà indirect object Some verbs have a different meaning depending on whether they are followed byà à à orà de, while other verbs require both prepositions:à à à and/orà de The expressionsà cestà andà il està have their own rules about which preposition follows:à cestà /à il està prepositions. Note:à There are also constructions with no verb à à à orà deà infinitive, a structure known asà passive infinitive. Whileà à à andà deà are the most common prepositions required after verbs, there are others as well: contredansenparpoursurvers And finally, a number of French verbs dont require a preposition whereas their English equivalents do: no prepositionà infinitiveno prepositionà direct object Some French learners find it helpful to memorize lists of verbs by the prepositions they require, as provided above, while others prefer a master list ofà alphabetized verbs.
