nbsp;nbsp;nbsp;nbsp;nbsp;Throughout â€Å"The Catcher in the Rye†, Holden Caufield longs for intimacy with other human beings. One of Holden’s main problems is that he sees childhood as the ideal state of being. He thinks that all adults are phonies. nbsp;nbsp;nbsp;nbsp;nbsp;One of the first relationships that is mentioned in the story, is Holden’s relationship with D.B., his brother. Throughout his childhood, it is obvious that Holden has idolized his older brother.

He pays her, but sends her back without having sex with her. He feels depressed and sorry for her. The next morning Holden has a date with an old girlfriend, Sally Hayes. Here, Holden desperately wants to escape the phony, corrupt world, so he proclaims his love to her, and asks her to runaway with him. She tells him that he is crazy and leaves him.

When are you gonna grow up?† (Salinger 144). At the time, they were talking about sex, and Holden acted very childish by frequently asking questions, and by becoming obnoxious. He even commented on how his own sex life is lousy. Luce then commented, â€Å" Naturally. Your mind is immature (Salinger 147). nbsp;nbsp;nbsp;nbsp;nbsp;Although Holden is extremely cynical and struggles with relationships, he is not all bad. Inside he is moral and generous.

Looking right of religion, technology and military power, people from these nations began to claim the land and lock up new worlds of natural resources to meet their needs, that is why some decided to immigrate to the United States seeking freedom and the opportunity for economical improvements; but this search for improvement, among other things, only brought suffering and death to Native American tribes.

The signing of these treaties and the adoption of policies and laws gradually declined sovereignty of indigenous nations. In the 1830’s, Five Indians Nations lived in territories that many Americans thought it might be more profitable for breeding, however, Americans could not do anything, because these tribes had signed treaties with the federal government, which guaranteed them the right to live in their ancestral lands and maintain its sovereignty; and it is not surprising that these notions were not willing to give up their land and to negotiate new treaties. That is why President Andrew Jackson decided that a new federal policy would be necessary to remove the Indians from their lands. This policy was called Removal Act of 1830, and gave the president the right to remove the five nations from their ancestral lands against their will.

Marijuana Subculture free essay sample

The United States has an approved list of drugs that are considered legal and illegal that create adverse side effects and hold diverse political views. Marijuana is a substance that popular media holds in a negative undertone while other drugs such as valid and alcohol are supported, if not glorified. Popular media is a powerful tool that gathers a mass of people and provides all types of information.Some types of information are historical facts, tactics, entertainment, opinions, and biases which alter the state and views of those who access it. Marijuana has had an extremely controversial political view throughout history and is considered a gateway drug, enabling users to pursue stronger and dangerous substances. Although marijuana includes negative side effects, statistics prove it may be far less dangerous to people and those around them compared to legalized substances with higher danger percentages.The comparison and political attitudes of marijuana throughout history of the United States is what is examined in this paper to draw wariness to readers on the bias of intolerance towards marijuana. I plan on limiting my topic selection by choosing a limit of 3 substances to compare the statistics against and only recording major milestones that changed the way people viewed marijuana throughout American history. The underlying argument in this paper would be in the form of an ultimatum: legalize marijuana or criminality alcohol and prescription pain medicine.The American people may not know why exactly marijuana is considered illegal when neither side effects or symptoms cause fatalities or crime when entrusted against prescription pain pills that target teenagers to adults. Alcohol related accidents are also significantly higher than marijuana related stresses however it has been considered wrong, immoral, and illegal for close to a century in United States history. The medias portrayal of marijuana in movies and television shows has always been a carefree and adventurous approach. Movies such as Half Baked, Harold and Kumar Go to White Castle, and Pineapple Express depict the substance as a recreational tool that can enhance the quality of life and entertainment. Television shows such as That asss Show demonstrate an accurate depiction of marijuana use in the sasss which show a group of teenagers sitting around a circle smoking marijuana, giggling, and eating. Although the sasss was known for heavy drug use such as cocaine, L SD, and heroin, and the governments epic battle on the war on drugs, marijuana was considered to be a gateway drug which led to endless possibilities and dangers.Throughout the sasss and sasss, marijuana was portrayed in negative connotations after President Nixon had declared a war on all drugs which was intended for the crack and heroin epidemic however extended itself onto marijuana as well. After the new century, the media began anti-marijuana campaign commercials that would be targeted directly towards teenagers. Tests of sensation s eeking targeting evaluated the effectiveness of targeted televised public service announcement campaigns in reducing marijuana use among high sensation-seeking adolescents, (Palmer, Denoted, Larch, Hole, Stephenson, 2001).This study used a controlled interrupted time-series design method to match 2 communities where one county and campaign Was compared to another county and campaign. Personal interviews were inducted with 100 teenagers in a period of 32 months. The result proved the effectiveness of media towards adolescents. All 3 campaigns had reversed the trend of marijuana use. Televised campaigns that target a large group of people have an effective strategy in conveying a direct message and achieving its purpose.The message that is being portrayed however is based off of false assumptions and lack of scientific data. It is simply opinion however the message and the powerful tool of the media conveys a strong image to impose a crime on the substance. The portrayal of other legal drugs in the media such as alcohol and restriction pills is far more appealing to the human eye than marijuana. Alcohol is branded with trademarks and celebrity endorsements that promote an urban lifestyle.It conveys the message that it is chic and savvy to drink or that it can bring excitement to a social setting. Celebrities, fancy cars, sports athletes, musicians, and scantily clad women submit a message through media that drinking their alcohol will allow a persons environment or self-image to be enhanced. Prescription pills on the other hand are not mentioned much in the media at all. The amount of danger and the argental of addiction is at such a great risk for Americans however there are no repercussions taken by government or doctors.With the number of soccer moms, teenagers, and role models (athletes, etc. ) that are getting addicted to these substances, it is abnormal that the federal government hasnt taken action towards monitoring or screening these substances as they do with marijuana. Marijuana charges for possession and distribution cost tax payers unnecessary dollars to keep law enforcement active, house non criminal inmates, and fund anti;marijuana regulations.In contrast, the argental of income the government and private corporations receive from alcohol and prescription pills keeps skyrocketing yearly even though the damage done to people and those around them from these substances is rather substantial. The dangers and problems of both alcohol and prescriptions pills in comparison to marijuana have alarming statistics and percentages that make readers astonished as to why marijuana is illegal or why other substances are legal.Alcohol has a long history of being portrayed in media as a relaxing elixir after a long day at work or a method of unwinding. The role of alcohol in ivies and television are false impressions of what would happen in a social setting if you were to be drinking a certain alcohol or the how much better your time would be spent if you wer e drinking. Commercials and advertisements use models, cars, celebrities, sports, clubs, and entertainment to promote an image or brand that alcohol brings life, love, and lust to any party however the cold hard truth is that it is far from the perception it sells.This multi-million dollar industry prides itself on a fast growing industry that has the highest percentage Of users of a social drug in the United States. We do not need the brewers reminder that the absolute quantity of alcohol consumed has been steadily increasing at a rate of at least 7% per annum to be aware that it remains far and away the most widely-accepted social drug in this country, (Add, 1981 , p. 48). Prescription pills have not been much of a harmful substance until this decade.The recent increase in those prescribed with pain and given very high doses of pain medication has been astonishing. Although these substances are intended to target the pain, most pain killers given through a prescription are misused and soon become addictive. A minor toothache or certain back pain that may not require such high doses of medicine are being prescribed by doctors which is leading to numerous amounts of dangers. A local mother who is prescribed pain killers can also be accidentally distributing to her teenagers who may not need the medicine or know how to properly ingest it. The effect of alcohol and prescription pills are a deadly combination but are extremely popular among youth. The combination of both legal substances enhance the altered state of mind one would naturally get from consuming just one substance. Prescription pain killers have been the major focus study among teenagers in the past 5 years due to the availability of them compared to the frequency of its distribution now. The assumptions on health effects caused by marijuana have different results after several tests.Many may presume that marijuana causes an array of mental disorders and lack of control of the mind however, Mitch Early. Vines research proves no such case. In general, the drug is incapable Of creating an overdose. It can exacerbate the symptoms Of some mental disorders but does not appear to cause them. Data fail to show any Arizona-induced changes in brain structure, but long-term exposure to the drug alters the way the brain functions during complex tasks, (Earliness, 2002, p. 143).Issues such as mental illness, anxiety disorders, psychotic disorders, antisocial behavior are linked to the symptoms of marijuana and although it does not cause any exact disorder, it may enhance those symptoms. Marijuana is now medicinally researched to cure disorders such as insomnia, anorexia, and minor pain. Cancer patients also rely on marijuana to increase their appetite, decrease nerve pain, and combat minor pain (Goodwin, 2010). Marijuana is a substance that comes with many pretenses and opinions that may be based on scientific fact or public opinion portrayed through the media. The tests, evaluations, and studies examined in this paper provide adequate information to the reader in establishing a proper factual idea on what marijuana is, the portrayal of the substance in the media, what its effects and dangers are, and its comparison to other legalized substances that are much more harmful. Although the United States has slowly shown progress in decontaminating marijuana and accepting the medicinal uses for it n states such as California, there is an underlying common misconception that marijuana is a substance of great danger, civil disobedience, and rebellion.

Added pressure of having time limits on math tests and exams also cause the levels of anxiety grow for many students. Where Does Math Anxiety Come From? Usually math anxiety stems from unpleasant experiences in mathematics. Typically math phobics have had math presented in such a fashion that it led to limited understanding. Unfortunately, math anxiety is often due to poor teaching and poor experiences in math which typically leads to math anxiety. Many of the students Ive encountered with math anxiety have demonstrated an over reliance on procedures in math as opposed to actually understanding the math. When one tries to memorize procedures, rules and routines without much understanding, the math is quickly forgotten and panic soon sets in. Think about your experiences with one concept - the division of fractions. You probably learned about reciprocals and inverses. In other words, Its not yours to reason why, just invert and multiply. Well, you memorized the rule and it works. Why does it work? Do you really understand why it works? Did anyone every use pizzas or math manipulatives to show you why it works? If not, you simply memo rized the procedure and that was that. Think of math as memorizing all the procedures - what if you forget a few? Therefore, with this type of strategy, a good memory will help, but, what if you dont have a good memory. Understanding the math is critical. Once students realize they can do the math, the whole notion of math anxiety can be overcome.

A Profitable Business Research Paper Example | Topics and Well Written Essays - 1250 words

A Profitable Business - Research Paper Example After adding up these costs, the value of unsold goods (closing stock) is deducted to give the cost of goods sold. When the COGS is deducted from total revenues from sales, the gross profit is achieved. Gross profit is also known as operating profit because it is a measure of the manufacturing operations of the business. Net profit is calculated after deducting general, selling and administrative expenses from the gross profit. These expenses include items like electricity expenses, depreciation, salaries of office staff, and other expenses related to the day to day running of the business (Pride, Hughes, and Kapoor 513). Sometimes, other income such as interest on loans, etc. is added to the gross profit. The net profit is a measure of the profitability of the business as it represents the amount that would be shared among the shareholders. For this reason, investors use net profit to determine the earnings per share (EPS) by dividing the net profit by the number of outstanding shar es. This tells investors how much return each share of the business earns for shareholders. 2. Misconceptions about Revenues and Expenses A common misconception new business owners have about revenues is that they are the same as profit. Revenues measure what a business received by selling its products. Profit is calculated after deducting expenses from revenues. ... Secondly, when accounting for business operations, the amount of revenue and expenses reported may differ. Under the cash-based accounting method, revenues and expenditures are identified when cash is collected or paid. But under the accrual accounting system, revenues and expenditures are identified when the right to receive or duty to pay has been established. The cash may be received at a later time. New business owners also sometimes fail to distinguish expenses from costs. For accounting purposes, cost is usually used to mean the price of a long-term benefit such as a fixed asset. On the other hand, expenses such as electricity payments and office stationery are payments in the course of the normal running of the business. Some new business owners also hold a misconception that all expenses involve payment of cash. In some cases, such as depreciation expense, there may be no payment of cash. Depreciation and amortization expenses simply involve the spreading of a cost over the p eriod during which the benefits of the cost are realized by the business. 3.

Otto Von Bismarck Term Paper Example | Topics and Well Written Essays - 750 words

Otto Von Bismarck - Term Paper Example First, after the defeat of Austria, it was expected that Otto Von Bismarck would make some demands for some territory from Austria, but instead, Otto Von Bismarck adapted the illogical strategy of failing to make such demands3. Otto Von Bismarck had sought excuses to start a war with Austria, by arguing that they had violated the Convention of Gastein4. Consequently, he charged the Prussian troops to attack Austria, but on realizing that the Austria troops were equally strong, he forged an alliance with Italy which was interested in some of the Austria’s territory in Venetia. This made the Austria’s army to be divided between fighting the Prussian troops and the Italian troops, thus losing the war. It is this illogical move that eventually resulted to the unification of Germany, through the unification of the German States, to combine forces in the Austro-Prussian War5. This is because, with the exclusion of Austria from Germany, then it was possible for Prussia to domi nate the German politics6. The other RealPolitik strategy applied by Otto Von Bismarck to achieve the unification of Germany was that of sustaining an enemy outlook with France. Otto Von Bismarck provoked France though trying to impose a German prince on the Spanish throne7. After the defeat of Austria, France perceived a united Germany as a major threat to the power politics in Europe, and thus made several attempts to unite with other territories such as Belgium and Luxemburg8. During such attempts, Otto Von Bismarck kept France advanced to the intrigues, but France did not win any of the territories, making France to be perceived as greedy and aggressive. This strategy was meant to ensure that the German states would unite under the Prussian authority, so that they would be offered protection against the perceived aggression from France9. Seeking to ensure that France would be seen as the aggressor against Germany, Otto Von Bismarck

Crime and Dye Lab Essay Example for Free

Crime and Dye Lab Essay Light is usually viewed as a result of the heating of a substance. The higher the temperature at which the substance is heated, the greater the vibrations that lead to certain light intensity given off by the molecule. It is this same theory that suggests why steel glows red hot when heated to high enough temperatures. The process of light emissions can also be induces through other means. 1 One of such means termed fluorescence occurs when a substance can be induced into giving off light is through absorption of a photon through light or other means of radiations. During this process, electrons are excited from their standard state. The electrons jump from their highest unoccupied orbital (HUMO) into a certain level of the unoccupied orbital (LUMO). As the electrons loose energy, they fall back to a lower orbital, thus emitting light. 1, 2 During the process leading to fluorescence, a certain change could occur during the excitation of the electron, changing the spin of the electron as it gets excited. This change has to be undone as the electron goes back to its standard state. The emitting of light in this process is known as phosphorescence. The process of fluorescence is much faster than phosphorescence. This is due to the fact that in phosphorescence, the electron has to undergo an extra step of undoing its current spin. This process is thermodynamically unfavorable compared to fluorescence. 1, 2 The last means by which light could be generated is through chemiluminescence. In such a case a chemical reaction occurs, causing an excitation of the product. As this product decays into its standard state, light is emitted. This form of luminescent is different from the previous two in the sense that no absorption of light is required to induce the glow. The glow results from the product of the chemical reaction having to be in an exited state or of higher energy. 1 The process of photon absorption and emission is certain a phenomenon that plays a vital role in our society. Such importance is expressed during rescue operations, where victims can be easily found due to waving of a fluorescent material at night. It is evident that fluorescence becomes important when a thermally induced light emission is deemed impossible. 1, 2 Separation techniques were concepts that were important in the course of this experiment. One of such is through the means of UV Vis Spectrophotometer. The constituents of ink dyes can be determined using a spectrophotometer. By placing the dyes in the spec, various wavelength peaks will be obtained. These peaks can be used to find out the constituent colors making up the dye. Another important form of separation used during this experiment is chromatography. Chromatography utilizes the differences in polarity of substances as means of separation. Such is the case of a crime lab involving the finding of a pen used in writing on a piece of paper. If a pen out of four is used to write a note, the particular pen can be detected using chromatography. The dyes of all four inks and the unknown ink can be obtained. This ink can be run through a chromatograph column, allowing a solvent to run above the ink dyes, carrying them along. After a certain point the RF values of all the inks can be used to detect the particular ink. The RF value is the distance the ink travels divided by the distance travelled by the solvent. The ink with the same RF value as the unknown is the same ink used. Chromatography has a wide range of use. It use can be stretched from this as it can also be used to indicate the component amino acids found in various proteins. The protein can be run through the column, resulting in the various amino acids that make the protein, to be separated. 1, 2 Materials and Methods (Summarized from Lab Manual) 1 Procedure * Phosphorescence Two different polyaromatic acids, 1- naphthoic acid and 4-biphenylcarboxylic acid, were obtained and drops were added unto two filter paper. The solvents heated to dryness for 11 minutes using a hot plate on low heat. The filter papers were then placed under long and short wavelength ultraviolet lamps. Observation of the intensity and duration of glow were recorded. * Fluorescence Tonic water was poured into a beaker. Long and short wavelength UV lamp was shined above the beaker. Observations were recorded. Now, a beaker of water was taking to the UV lamp and was shined at the beaker. Observations were recorded. After, 3 drops of concentrated fluorescein solution was added into the beaker. The UV lamp was shined above the beaker and observations were recorded. * Chemiluminescence 2 mL of Tekrakis-(dimethylaminoethylene) was added into a small test tube. This test tube was taken to the UV lamp and shined at. Observations about the intensity and duration of glow were recorded. After, 1 mL of luminol in DMSO was added into five test tubes. Now, in each test tube fluorescein, rhodamine, rubrene and perylene solutions were added in 4 four of the five test tubes. Observation of the color of each solution was recorded. At this point, 1M NaOH was added into each test tube and was then shined with a UV lamp. Further observations were recorded. Finally 1 g of Al2O3 was added into four 250 mL Erlenmeyer flask. This was mixed with 1 mL of 3% H2O2. In each flask, perylene, tetracene (2,3-benanthracene), 9,10-Dipehenylanthracene, and rubrene were added respectively. Now, 1 mL of oxalic chloride was added in each flask and swirled. Observations were then recorded. * Crime Lab A water bath was heated and maintained at 650C. Now, scribbles were made on papers from each of the four pens. The paper with each scribble was cut into small pieces and placed into a marked test tube. Also, a scribble of an unknown pen was obtained. The paper was also cut into small pieces and placed in a test tube. 2 mL of methanol was added into each test tube and was placed in the hot bath for 5 minutes. The test tubes were allowed to cool, the color of the inks were recorded and poured into five cuvettes. Using a UV-Vis spectrophotometer, the wavelength peaks and absorbance of each ink solution were recorded. Four of the five dyes were then poured into new marked test tubes. The solutions were then boiled for 14 minutes until the there were less than 1 mL. The solutions were allowed to cool. Now, a 250 mL beaker was obtained. In it was added a small amount of methanol (less than half a centimeter in height). A filter paper was then obtained and cut towards the end (B.1). This was placed at the side of the beaker. Finally, an alumna plate was cut in the dimension of 8 x 4 cm. A line was drawn at a 1 cm height using a pencil. In this line, drops of the four inks were spotted. This plate was then leaned inside the end of the beaker (B.2). The plate was left in the solvent until it reached  ¾ of the way up. The height the inks and solvent reached up the plate was recorded.

The Guilt of Macbeth and Lady Macbeth Essay -- Macbeth essays

     Ã‚  Ã‚  Ã‚   Characters in the Shakespearean tragedy Macbeth scarcely feel guilt - with two exceptions: Macbeth and Lady Macbeth. In this essay let's consider their guilt-problem. In his book, On the Design of Shakespearean Tragedy, H. S. Wilson comments regarding the guilt of the protagonist: It is a subtler thing which constitutes the chief fascination that the play exercises upon us - this fear Macbeth feels, a fear not fully defined, for him or for us, a terrible anxiety that is a sense of guilt without becoming (recognizably, at least) a sense of sin. It is not a sense of sin because he refuses to recognize such a category; and, in his stubbornness, his savage defiance, it drives him on to more and more terrible acts. (74) Blanche Coles states in Shakespeare's Four Giants that, regarding guilt in the play: Briefly stated, and with elaborations to follow, Macbeth is the story of a kindly, upright man who was incited and goaded, by the woman he deeply loved, into committing a murder and then, because of his sensitive nature, was unable to bear the heavy burden of guilt that descended upon him as a result of that murder. (37) A.C. Bradley in Shakespearean Tragedy demonstrates the guilt of Macbeth from the very beginning: Precisely how far his mind was guilty may be a question; but no innocent man would have started, as he did, with a start of fear at the mere prophecy of a crown, or have conceived thereupon immediately the thought of murder. Either this thought was not new to him, or he had cherished at least some vaguer dishonourable dream, the instantaneous recurrence of which, at the moment of his hearing of prophecy, revealed to him an inward and terrifying guilt.

Is Google Making Us Stupid?

Google is an internet search engine that allows users to find information on any given topic. Google was created in 1996 and has been one of the fastest growing sites ever since. Google makes it possible for any information that is needed to be available at the click of a button. Some people think Google is the best thing since sliced bread, but Nicholas Carr has another opinion. Personally, Carr thinks it could be dangerous to our minds having so much technology at our fingertips. If we go back to the early days, when the Internet was not available, people had to research deeper than they do now.They spent hours and hours in a library, searching through books and newspapers. As time progressed, society started developing and new inventions were made. Friedrich Nietzsche started using a typewriter after his vision started failing, and his writings began to change. He went from â€Å"arguments to aphorisms, from thoughts to puns, from rhetoric to telegram style† (Carr 636-67). Frederick Taylor â€Å"created a set of precise instructions† that would have â€Å"maximum speed, maximum efficiency, and maximum output† for factories to use around the world (Carr 638).Taylor’s â€Å"system† made factory’s productivity soar. With these new ideas and inventions, the world began to change and now has come to a place where everything is relied on by the Net. â€Å"It’s becoming our map and our clock, our printing press and our typewriter, our calculator and our telephone, and our radio and TV† (Carr 638). Carr relates to the changes the Net brings to our lives. He says, â€Å"the Net is becoming†¦the conduct for most of the information that flows through my eyes and ears and into my mind† (634).He has stopped doing all the hard, time-consuming work that was once required to do as a writer. Using the Internet is the easy solution to finding out anything you need to know and Carr believes it is changing how his mind focuses and takes in information from any articles or essays he reads. The amount of time that a person stays on the Internet could have a negative effect on them. A person searching for information on the Net should limit themselves to a certain amount of time on it.Moderation is the key to protecting yourself and your brain from becoming completely dependent on the Net. Carr even confesses that he spends more time on the Net now than he ever has. Obviously, the Net is not completely awful. It helps find information so much faster and has articles so much easier to read. But, if we let the Internet reteach our brains how to think then we will have a problem. Carr is basically warning us that if we do not moderate our time on the Internet then the Internet will begin to control our mind and thoughts. Is Google Making Us Stupid? â€Å"Is Google Making Us Stupid? † In the article, â€Å"Is Google Making Us Stupid? ,† Nicholas Carr implies that he notices that something is causing his brain to change. He realizes that he is not thinking the way he used to think, especially during reading. While reading in the past, he explains how he would be able to engage in long articles or books, but now finds his concentration drifting away after just a couple of pages. He began to realize these differences since he has started utilizing the internet.Carr aims to convince his readers that our brains are trying to move at the same rates as the internet, skimming rather than completely soaking in new information. The internet is creating a new method of learning, much different from the traditional book or printed way of learning. Carr supports his belief by describing how intellectual activities are being replaced by technology, the development of the â€Å"one best method†, and Google’s motive to make the internet more accessible.Carr begins his essay with the example of Friedrich Nietzsche and his story of the typewriter. Friedrich Nietzsche was a 19th-century German philosopher, poet, composer, and classical philologist. He suffered from dementia after becoming paralyzed from a stroke. Losing his ability to write by hand, Nietzsche bought a typewriter and was able to write again. Carr uses him as an example because it showed how even though using the typewriter efficiently allowed him to write again, it changed the form and skill of his writing.Nietzsche was reprogrammed, but this time with a lesser software. This example shows that Carr is clever and witty with his comparisons. He provides another example that timekeeping instruments are taking place of our biological clock and people are relying on the clock rather than their own senses. This example corresponds with Carr’s belief that intellectual activities are being replaced by technology, or being reprogram med. Following his idea of reprogramming, Carr explains the development of the â€Å"one best method† created by Frederick Winslow Taylor.Taylor used this method to determine how each worker can use his time wisely enough to get their job done in the shortest amount of time. This example foreshadows another example that Carr uses later in his essay. This system that Taylor created directly relates to the structure of the internet today. It is apparent to the reader that internet programmers are trying to find the â€Å"one best method† to make all the information that one person could need as accessible as possible, in the quickest manner. Google is the internet at it’s finest.The final point that Carr discusses is Google’s effort to try to make the internet as accessible as possible because the faster we can use it, the faster they can market information that appeals to us individually. This is how Carr uses Taylor’s system to support the topic th at is at issue today. Carr explains how the co-founders of Google are pushing to make their search engine into an artificial intelligence. This addition in the paper intrigues the reader, making them curious about how far this will actually go.The point that Carr is trying to get across is that the skepticism on the development of writing and the invention of the printer, differs from the skepticism that we have today about the internet. Reading and writing causes our knowledge to expand into detail, while the internet causes our knowledge to expand into topics. Due to the assumptions that browsing the internet makes it hard to demand your full concentration for long periods of time, people are starting to feel as if they are becoming stupid.

It’s becoming our map and our clock, our printing press and our typewriter, our calculator and our telephone, and our radio and TV,† Writes Nicholas Carr in his article, Is Google Making Us Stupid? In Carr’s article, he examines the controversial issue of whether the intensive use of the Internet affects the human mind. Today, the Internet has become apart of and has affected a myriad amount of homes all around the world. From social networking, research, and even online shopping, the Internet is the main used device everywhere.When it comes to the Internet, the one thing that immediately comes to mind is the most common search engine, Google. Google is the most common multilingual and used search engine in the worldwide web, handling more than three billion searches each day. Many people think of Google as a gateway to the entire Internet. Goo gle helps people to get answers to questions without intellectually challenging themselves. This search engine has helped, and still does, many people around the world to research articles, tools for business; to contact one another, and many other life-applied sources in less than 1 second.Having Google grant us an effortless method in researching essentially anything helps us become unintelligent or in other words, stupid.

The effort given into researching through textbooks about the topic vs. using Google does help us gain more knowledge by helping memorize and understand the topic more efficiently and clearly. As in school for researching to prove a specific topic, teachers occasionally have a preference of not using a search engine since we never know what is true and to avoid plagiarism. Google on the other hand, would give us the answer even in detail, but we do not know if it is the right answer.Everything on the Internet is not always true. Google can, as well, make us intelligent. To become universally familiar with technology and how it is improving everyday can help us all with our lives in the future.

What is the main claim/thesis?The main claim, or thesis, is that the more dependent we become with computers and other technology, the more our own intelligence declines and the more brain-dead we become. According to Kubrick’s dark prophecy, by using this technology to understand different aspects of the world, we are generating artificial intelligence.What are the means of support for the claim?The means of support Carr uses are personal testimonies, examples, and appeal to logic and value. He uses himself as a support because he admits to being a victim of his argument, he says â€Å"for more than a decade now, I’ve been spending a lot of time online, searching and surfing and sometimes adding to the great databases of the internet. A few Google searches, some quick clicks, and I’ve got the fact or quote I was after.† By stating this, he is showing how easy it is to become caught up in the convenience of the internet.He uses himself as an example becaus e most Americans can relate, and understand where he is coming from. Everyone knows that Google, or other internet search engines, make gathering information easy, however many do not realize what it is doing to their brains. Carr uses fact and an example of research done by scholars of the University College London, who were a part of a five year research project to explain how much our research habits have changed over the years. Carr’s writing causes reader’s to use logic and values when thinking about how often they use the internet, and what they are using it for.Do the support strategies sufficiently prove the thesis?The support strategies that Carr uses support his thesis to an extent. He explains how technology is ruining our brains, but he also contradicts himself by pointing out how regularly American’s use technology, and how often we need it for everyday tasks. His support strategies may have been better if he used more facts, or research done on why technology is destroying our brains with artificial intelligence.â€Å"The human brain is just an outdated computer that needs a faster processor and a bigger hard drive†, this statement Carr makes contradicts his argument in a way because it shows that since we have access to bigger hard drives and fast processors outside  of our brain, we should be using it. He does not intend to sound hypocritical; however his way of appealing to logic goes against his argument because as humans, we have come to accept the new forms of technology and the fact it could be destroying our brains.How does the argument address opposing claims? Are those claims sufficiently refuted? The argument addresses opposing claims in a logical way. Carr gets personal with the readers, in a way that they understand what he is talking about and where he is coming from. The opposing claim, being we need technology, was not addressed on a level where humans will go against using it. He explains that by usi ng the internet, we are gaining artificial knowledge, but losing our real knowledge.I think there are some people who will be shocked by this and by reading about how technology is changing us, but for the most part I think America has become okay with the idea that our brains are decreasing, while our use of Google is increasing. We have accepted the fact that soon we will be full of ‘fake intelligence.’ Does the argument concede to outside positions? What is the effect of those concessions? The argument Carr makes puts the outside position into perspective. The concessions show that Carr acknowledges, and has an open mind to the opinion of others. He values that American’s do need some basic technology, and that it can be very useful, while he also states that it can come to be a problem when it controls our lives. Does the writer define the issue correctly?The writer does define the issue, as the more dependent we become on technology the more brain-dead we be come, correctly. He does a good job of explaining what is happening, and the different psychology and neurology effects the internet has.What is the warranting assumption?The warranting assumption is that by only depending on technology and internet for our understanding of the world, our real intelligence is likely to decrease, while we gain artificial intelligence.Is the assumption acceptable or arguable?This assumption is questionable, because while there is evidence showing more people are depending on technology, there could also be arguments that some internet sites increase our intelligence. Can I prove the assumption is incorrect?Yes, there are ways to prove that technology is helpful, and has a positive effect on society. For example, without the improvements in technology we would not have the information or access to advances in energy, medicine, cures for diseases, or education.What else does the author of the argument assume?Carr assumes that all people have access to n ewer technology. He believes that it is common for everyone in the workplace to have new cell phones, and computers. He also assumes that humans depend on technology for everything, which is why Americans have become more oblivious to things happening around them. He believes that everyone will fall into the trap of internet, and in a way will become hypnotized by it, when in reality, many people may not even have access to the internet or the new technology.

Discuss How the Passage Contributes to the Portrayl of Faustus as a Tragic Hero Essay

Discuss how the passage contributes to the portrayal of Faustus as a tragic hero, paying particular attention to Marlowe’s use of language. Marlowe uses language in the passage from Act Five, Scene One to portray Faustus as a tragic hero, his use of the techniques; enjambment, metaphors and rhythm show this portray. Marlowe uses enjambement to show Faustus as a tragic hero because he now regrets his choice to sell his soul this is shown in line 86-87, ‘whose sweet embracing may extinguish clean these thoughts that do dissuade me from my vow’ although Marlowe has written these as an attempt to blackmail Mephistopheles, the use of enjambement makes the line sound rushed which makes it sound more like a desperate plea thus showing how much Faustus regrets his decision, since this is near the end of the play this is suggesting that Faustus fears eternal suffering rather than actual remorse. Faustus asks for Helen to come to him to be his ‘paramour’ this suggests that Faustus is using his sexual desire in order to ‘shut out the truth that he cannot face’ again showing his fears of eternal suffering this shows Faustus as a tragic hero because he now regrets selling his soul to Lucifer and he can do nothing to stop his fate. Marlowe uses metaphors in order to show Faustus as a tragic hero as he shows Faustus’s desire to win back his soul even though he will not prevail. In line 95, ‘her lips suck forth my soul. See where it flies! shows Faustus desire to be free as flying is used as a connotation for freedom however the line also foreshadows the ending of the play as he is dragged in to hell, showing that Faustus is a tragic hero as he desires control over his soul again but will not be triumphant. The line 102-103 ‘yea I will wound Achilles in the heel and then return to Helen for a kiss’ is a metaphor used to show Faust us’s desire to win in the battle with Lucifer. Marlowe uses Achilles who had one weakness to show Faustus’s struggle and his desire to regain control of his soul in order to avoid eternal suffering thus depicting Faustus as a tragic hero. Marlowe uses rhythm of the play to show how quickly Faustus’s fate approaches him. In lines 98-99 Marlowe uses the image of a fast paced war to show Faustus will not win the battle for his soul ‘I will be Paris, and for love thee instead of Troy shall Wittenberg be sacked’ Faustus compares himself to Paris who was defeated in the battle of Troy, this foreshadows the ending of the play as it is Faustus who loses the battle for his conscience as it is now too late to repent. Marlowe also uses enjambement in this line to show the fast paced rhythm the way one line tumbles into the next shows time speeding up showing Faustus as a tragic hero. Marlowe uses certain techniques in language in order to portray Faustus as a tragic hero as he cannot change his fate even though he wishes to through enjambement, metaphors and rhythm.

Free sample - Usage of Internet and Email. translation missing

Usage of Internet and Email. Usage of Internet and EmailNowadays it is very difficult to imagine modern world without computer technologies and using of computer programs as practically every sphere of our life is connected with them. Computers and Internet constitute rather big part of business life, as it is very difficult to control work without computers and Internet (Soong, 2010, p. 15).   It is understood that with the appearance and development of Internet, it became one of the most effective methods of influence, controlling and sharing information. Internet and everything that is connected with cyber industry affect people greatly. Such democratization of Internet and IT technologies means people are able to share their points of view and visions of certain problems despite their geographical location (Hatchen, 2000, p. 34). People can share messages by means of internet with the high speeds because they are shared by means social networks. It means that everyone is struggling for attention and place in a media environment. This environment now is cramped with information. Needless to say, that modern society is very dependent upon Internet and popular networks that became inevitable part of life of every user.   Every day life is hard to imagine without Internet and IT technologies. With their help, it is easier to tell the public about technological improvements and events from social and political spheres.   Whatever the reason or interest is, any person has the opportunity to transmit a message through the Internet and this massage can be potentially heard by thousand of people all over the world. This means of taking information is very hard to substitute. I am a current employee of the company dealing with the development and delivery of the trade equipment. In our company, the use of Internet and corporate email has become an inevitable part of the working process. The use of e-mails as a means of sharing information and communication becomes very popular in any company or organization, as this is a very simple process requiring minimum time and strengths. This means of communication and sharing the data and information is very popular and widely spread from the point of view convenience and time-consumption. The development of Internet and its implementation made the process of communication easier and faster. It gained great popularity among the employees, as Internet allows being aware of the information necessary for the production process and communication. As usual, every company is provided with the personal server that is able to serve the consumers of the company, where every employee is provided with the personal corporate e-mail address in order to communicate and share messages within the company (Kirshenbaum, 2009, p. 23). As a rule, the content of the shared information and emails is strictly controlled by the management of the or ganization in order to prevent frauds, viruses and leakage of personal and corporate information. In this case, the companies make use of the privacy policy. One of the main aims of such policy is to prevent computers from the illegal access, use of information by the third persons and fraud and viruses invasions. In my company, this kind of policy is provided by means of computers’ protection from outside users. The IT managers entitled to use the personal information of the employees to protect it from illegal utilization. It is one of the most popular and reliable measures, as not every employee can distinguish potential danger and see that the E-mail box, containing his or her personal information, stored in his computer was broken and used. There are a lot of measures the companies should take to protect and guard their networks. A good safety plan outlining essential safety measures is required for quick reply and disaster revival. Auditing, tracking and constant monito ring of the network should be conducted to distinguish leaks and intrusions. Moreover, different kinds of firewalls and other appliances of software and hardware can become helpful for discouraging network intruders. A great number of companies use some regulations and laws that are developed to protect personal information of the employees stored in their computers. This is the email privacy used by very company on the legal basis. Email privacy was elaborated by the US government and is derived from the Fourth Amendment to the U.S. Constitution. This policy is governed by the standard of reasonable expectation of privacy. According t this policy, the managerial of every American company is able to control e-mail and Internet use of the employees during their working hours. Moreover, the regulations of the privacy policy presupposes constant monitoring of email boxes and websites visited by he employees within working day. Most employers make their employees sign a computer and network use policy that usually sets forth that their email should be to be used merely for business purposes and entitles the employer to monitor usage of email and computer.   This agreement usually deprives an employ ee of any rational expectation of privacy, and means that the emails of the employees are fair game for the employer to seek through.   Employers, disparate from law enforcement, do not have many obstacles averting them from checking the emails of the employers. It is only a matter of business as the employees should take into account the fact that theory can cause difficulties to their business, that is why, the main aim of the agreement of privacy policy is to protect the company, but not to adversely modify the rights of the employees (Levmore and Nussbaum, 2010, p. 45). Privacy policy measures are forwarded to protect company from illegal usage and leakage of business information through the emails of its employees. Every company should control usage of Internet usage and content of email messaging. It is regulated by the current legislation and every employee should stick to the laws of privacy policy. The employees realize that the privacy policy is very significant for the both, them and their company. It is an inevitable part of the policy of every company used to prevent the leakage of company’s information and preserve the order within the organization. As usual, privacy policy does not have any negative effect on the employees. Indeed, it makes them more careful and watchful concerning the problem of security and privacy, as privacy at work is a half of success of every organization.

The Human Resources Department Changing Role - Affirmative Action, Research Paper

The Human Resources Department Changing Role - Affirmative Action, Californias Prop 209, and the emerging trend of Cultural Diversity - Research Paper Example Prior to Affirmative Action, African Americans, Asian Americans, women, and other minority groups found it doubly hard to find jobs. Discrimination of the minority groups and women can be based on the individuals’ color, gender, national origin or religious beliefs. Affirmative action violations include discrimination on the basis of employees’ promotion, salary, or other work benefits. Likewise, universities refused to accept African American students and students from other minority groups. The police force implemented discrimination in the hiring of police officers. Affirmative action requires all schools to allocate a certain percentage of the total student population to minority groups. Affirmative Action offers preference to job applicants or employees belonging to the female gender, non-white job applicants, and the job applicants’ ethnicity. Under the act, the disparate impact computation was launched (Holzer, H., David, N.,, 2010). A survey conducted in 2005 shows that more than 50 percent of the people favor the support for the minority groups’ desire to have equal job opportunities for women. The same research shows that more men prefer the implementation of the Affirmative Action provisions than women (Myersetal, 2007). For example, the University of California’s school of medicine allocated a quota of 16 of the total available student enrollment slots to the minorities and women enrollment applicants. When Allan Bakke tried to enroll in the school, Bakke passed the medical school entrance tests. However, he could not be accepted because the 16 enrollment slots were reserved for the minorities and women school enrollment hopefuls. Bakke sought the United States Court’s intervention. The court required the school to accept Bakke’s enrollment on the ground that Bakke’s constitution right to equal

Structural analysing Essay Example | Topics and Well Written Essays - 1750 words

Structural analysing - Essay Example Today, an SEM has become an indispensible instrument for any R&D or production set up dealing with advanced materials science. In the subsequent sections interaction of electrons with matter, basic principles of electron microscopy, architecture and working of scanning electron microscope, different attachments to an SEM and applications of SEM in materials science will be discussed in brief with special emphasis on specifications of a modern SEM. Interaction of Electrons with Matter Electrons as a probe are extremely versatile as they generate a wide range of signals which can be detected and processed to get useful and meaningful insight about surface topography, microstructure, microchemistry and micro-texture of the material being probed. Different kinds of signal generated as a result of interaction of electron probe are shown in Fig. 1 [1]. Fig. 1: Schematic Drawing Showing Electron – Matter Interaction When thickness of the specimen is less than ~ 100 nm only then the i ncident electron beam is able be pass through it and generate different kind of transmitted signals. However, the transmitted signals are relevant for Transmission Electron Microscope (TEM) and not for Scanning Electron Microscope (SEM); therefore, we will not discuss about transmitted signals here. Among the reflected signals secondary electrons (SE) and Back Scattered Electrons (BSE) are relevant for SEM for imaging and characteristic X-rays are useful for chemical analysis in SEM. Besides, BSE is also useful in micro-texture analysis using Electron Back Scattered Diffraction (EBSD) attachment. Therefore, we will limit our focus to these signals only. Secondary Electrons (SE) These are low energy electrons (less than 50 eV) generated after the incident beam hits the substrate. Back Scattered Electrons (BSE) These are high energy electrons (more than 50 eV up to beam energy) generated after the incident beam hits the substrate. Characteristic X-Rays When electron beam strikes the s pecimen, it knocks out the inner shell electrons and the vacancy thus created is immediately filled by an electron from higher shells. This electronic transition leads to generation of X-rays which are characteristics of the element. Thus these X-rays can be used for micro-chemical analysis using Energy Dispersive Spectroscopy (EDS) and / or Wavelength Dispersive Spectroscopy (WDS). Basic Architecture of SEM Basic architecture of an SEM is presented in Fig. 2 [2]. It is a column always under vacuum consisting of different subcomponents. It consists of an electron gun or electron source. This can be different types, which will be discussed afterwards. This is followed by condenser lenses to focus the beam. There are apertures in the path to allow only and an aperture to allow only the useful (central) portion of the beam to the subsequent stages. The focused beam is double scanned and made to pass through an aperture to fall onto the specimen. The beam is scanned over the specimen in a raster and the generated signals – secondary or back scattered electrons are collected, amplified and again scanned in a raster onto a CRT screen in synchronized manner. Thus image is formed pixel by pixel. The magnification is ratio of

Physician Billing research paper Example | Topics and Well Written Essays - 750 words

Physician Billing - Research Paper Example A more specific term comes out of medical billing is the physician billing which has eight potholes: previsit process, patient check-in process, charge capture and entry process, claim process, payment posting process, account follow-up process, denial management process, and patient collections process (Walker, Larch, and Woodcock, 2004). Each pothole must be avoided at all cost to ensure the smoothness and speed of the billing process. Physician Billing In all types of businesses and professional practices, transactions are inevitable and the one giving the service will get to earn from his efforts while satisfying the needs of the clients. Nobody can deny that money is a need to be able to facilitate exchange and to allow anyone to purchase his needs and wants. In the process of transactions, billing is a primary concern. According to Business Dictionary (n.d.), billing is the â€Å"process of generating an invoice to recover sales price from the customer and is also called Invoi cing.† In the process, the business earns revenue wherein profits are made and the expenses of the business for the service are also covered. In other words, invoicing is important that the organization facilitates the process of getting paid after the service or product is delivered to the client which includes having billing accounts. In that way, invoices are matched with the orders, efforts, and transaction records and for tracking the payments (Silverston, 2001). In the medical field, business is inevitable as hospitals and healthcare providers need to earn revenue to cover their operating expenses. For physicians, they need to earn profit from their expertise by assisting people with their physical ailments. For that reason, medical billing comes to life. Medical billing involves coding as the process is made to assist the physicians in processing insurance and medical claims effectively. The process involves handling patient invoices and taking care of reimbursements. T he reimbursement process contains the medical procedures and services rendered by medical doctors. As the processing of the billing becomes a career, a number code system had been created to assist the encoders in inputting the data with ease as numbers represent certain disease or injury. A software assists the medical billing representatives in recording the procedures and let the insurance software interpret the code flawlessly. In that process, reimbursement is quick and physicians get their professional fee promptly. As medical billers do the job, they must understand the technicalities in the medical field like terminology, disease, anatomy and many more. They must be dependable in terms of knowledge, skills, and job habits and must have the knowhow when it comes to technicalities in invoicing (McGarry, 2003, p. 82). For those who plan to become a medical biller or choose medical billing as a career, they need to understand the basics and not just the definition of the work. F or some, medical billing is considered as business since they do the stuff at home and online. They are not employees that need to go to work in hospitals or offices everyday with scheduled fix time. Since technology has been advancing rapidly in the past years, internet becomes a powerful tool to start a business or career without leaving the house. The trend nowadays is the electronic medical billing that requires a personal computer to perform the tasks. It is

Differentiate Between Stress And Strain Engineering Essay

Differentiate Between Stress And Strain Engineering Essay When stretching a material, the length changes and the strain become positive. More strain means that more stress to the object once compress. When the material is compressed, the length changes and strain becomes negative. This obeys to the law of the stresses where go together with these strains, tensile stresses being positive and compressive stresses negative. http://studentweb.usq.edu.au/home/w0036795/etassgn_4/images_unit02/unit2_image36.gif Figure above shows the relationship between stress and stain as the stress is directly proportional to strain. There is a relationship where the force applied and the object changing in physical shape. It has revealed that the elastic behavior can be defined thru some relations with the form that the physical state changes is small in related to the original. This relationship can defined as Hookes Law ( F = -kx) Question 2 Pyrometer is used for measuring temperature. Discuss in details four principal techniques for the measurement of temperature. State the typical applications of different types of pyrometers A pyrometer used to measures heat from an object which has visible in bright or radiant. Pyrometers consider as thermometers where scientists use it to define the heat and heat type given out from an object. The critical variation between a pyrometer and other types of thermometers is the radiant levels on or after the heated objects are typically far too hot for interaction. That is why pyrometers have visual scanners that measure the heat. Four principal techniques for measurement of temperature. IR Pyrometers for Surface Temperatures The spectrum lies at wavelengths longer than light however shorter than microwaves or measuring system. IR pyrometers usually operate with wavelengths from two to twenty microns, reckoning on the material being measured. Plancks law states that the emissive power of a black body contains a spectral distribution reliant on the body temperature. This can be a well-known matter, thus there are numerous strategies to avoid this matter with variable target emissivity. IR Gas Temperature Pyrometers IR pyrometer functional at a wavelength consistent to the combustion emitted products, such as CO2 gas radiation (at 4.26 or 4.5 microns) can measure average gas temperature. This method needs gas to be combusted, meanwhile air not having a sturdy IR emission peaks. All fossil fuels produce CO2 after when it burnt, so this method is appropriate to oil and propane fired furnaces, but not for electrically heated furnaces. The temperature of the gas stately is the radiation temperature of the CO2 gases in the field of view of the lens, so choice of lens and placement is significant. 2 IR pyrometers must be located on opposite sides of the furnace to portion this temperature inhomogeneity. Whatever that blocks the assessment of the lens (as soot or dust), air penetration (less CO2 to measure temperatures) or huge differences in gas temperature with time can create the average temperature signal too strident to use straight in a control system. ACOUSTIC PYROMETERS Acoustic pyrometers is a method where used to measure the temperature of gases created on the temperature reliance of the speed of sound. The speed of sound diverges through the square root of the total gas temperature. This method stretches an average temperature completed an identified path length if the gas composition is identified and continuous. Guileless acoustical pyrometry uses the time of flight statistics for the leading wave front to reach the receiver. This is suitable on behalf of an average gas temperature for one path. The wavelengths may exist to be enormous, for instance, presumptuous a sound velocity of 880 m/s at a frequency of 500 Hz stretches a wavelength of 1.8 m. Ruptures of air can remain the basis of sound, giving an informal to connect, low-maintenance instrument. Numerous paths can be selected, which can be examined to provide 2D isothermal maps of furnace temperature problematic to crop by other resources for gas temperatures of 1650Â °C. Advantages of a coustical pyrometry embrace modest and rough equipment for industrial environments, numerous paths subsequently a single transmitter for a least amount of holes in the furnace walls for 2D temperature mapping, low operating costs and proven technology. Suction pyrometers Suction pyrometers are a method where suction is used to appeal the hot combustion gases past a thermocouple at a great velocity to decrease the fault in gas temperature measurements. Radiation shields reduce the thermal effects of radiation. Suction pyrometers are still the best industrial apparatuses for measuring combustion gas temperatures, for instance, they are used for impermanent gas temperature measurements at a specific position or for calibration of other temperature measurement apparatus. The micro suction pyrometer has been established to evade countless of the disadvantages of the suction pyrometer. Main disadvantages with micro suction pyrometers comprise their lesser accurateness and additional brittle construction comparative to conservative suction pyrometers. Types of pyrometers Broadband Pyrometer The broadband pyrometer is used to record the broadband wavelengths of radiation, typically about 0.3 microns. However furthermost repeatedly used, they can have big mistakes in readings. Subsequently they are merely registering a minor quantity of an object heat. Everything from water vapor to dust can produce a reading error. Optical Pyrometers An optical pyrometer let a scientist to observe heat though all pyrometers are optical in the sense they can recite an objects heat from a distance. An optical pyrometer is used to measures the heat infrared wavelengths and straight displays the manipulator the object heat distribution. Additional pyrometers typically have a screen to shows the results of an optical scan. An optical pyrometer can act lie a telescope where the scientists can look over a lens and see the infrared wavelengths of an object. Optical pyrometers are one of the oldest pyrometer types and are able to see the wavelength levels up to 0.65 microns. Radiation Pyrometer A radiation pyrometer is used to determine pure radiation wavelengths. The device contains an optical scanner that can perceive 0.7 to 20 microns on the range of wavelength, the overall range for radioactive heat. The optical scanner lightens the burden of scientists in measuring the radiation levels without putting the pyrometer up to the object, where it can endanger the person in charge to expose to radiation. Question 3 Draw the functional block diagram of Electrocardiography (ECG) machines and explain each in details. From the functional block diagram, answer the following: 1. What (electrically) is being measured? 2. How is the electrical signal capture? What is the sensor? How does it work? Draw a complete circuit to represent the functional block diagram What is ECG? An electrocardiogram or ECG is used to measure and analyzed electrical recording of the heart and even used to investigate heart disease. British physiologist Augustus D. Waller is the creator of electrocardiography and published the first human electrocardiogram in the year 1887. Dutch physiologist Willem Einthoven, who transformed this inquisitive physiologic phenomenon into a crucial clinical recording device, was awarded a Nobel prize in medicine. Block diagram of ECG http://edge.rit.edu/content/OldEDGE/public/Archives/P05903/WebsitePics/ECGsetup.JPG When the heart depolarizes, its suitable (and quite precise) to denote the electrical activity as a dipole which a vector between two point charges. A vector has both a size (magnitude), and a direction. The potential diverges around the volume conductor. This applies to all intra-cardiac events, so the vector (or axis) for P waves, the QRS complex, T waves, and so on. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEinpswj9DBqjb_6Yj-c-N4-krVsMM9xAZvVXiCmeypjjyepPcHBpahF9GNrA11jE9zN7k9D2vZOryBCVgInsw2ir3heDfrHaEW0g4h_S0A8PzeMaAVmupO9gwdbHZt6yoWKn5nZZjINsts/s1600/3-lead_ecg-signal+measurement.jpg The electrocardiogram, or ECG is a surface measurement of the electrical potential produced by electrical action in cardiac tissue. Current flow in ion form and signals shrinkage of cardiac muscle fibers foremost to the hearts pumping activity. The human heart can also be considered as a large muscle where the beating is just contraction of muscles. Consequently contractions of the heart create a potential. The measurement of the potential created by cardiac muscle is called as electrocardiology. Types of electric is being measured a) Bipolar leads: The position point located on one limb, the `sensing electrode can be on another limb. The leads are mark as I, II, and III. b) Unipolar leads: The position point located in some leads that joined together, and the sensing lead is located on one limb. These leads are predictably increased, in that the position lead on the limb sensed is disconnected from the other two. c) The V leads : The position where lengthen across the precordium, V1 in the fourth right interspace, V2 4th left, V4 at the apex (5th interspace, midclavicular line), V3 halfway in between V2 and V4, and V5 V6 in the 5th interspace at the anterior and mid axillary lines correspondingly. These electrode leads are usually connected to potential differences devices between selected electrodes to create the specific ECG tracings. Majority of the ECG leads are bipolar leads (e.g., standard limb leads) that apply a single positive and a single negative electrode amongst which electrical potentials are measured. Unipolar leads (augmented leads and chest leads) consist os single positive recording electrode and apply a blend of the other electrodes to assist as a merged negative electrode. Typically, once an ECG is recorded, all leads are recorded instantaneously, normally called as 12-lead ECG. How is the electrical signal capture? What is the sensor? How does it work? Cardiac electrical potential wave forms (voltages created through the heart as its chambers contract) are measured by the PASCO CI-6539A EKG (Electrocardiogram) Sensor. The sensor contains of the electronics box by a cable for connecting to the PASCO computer interface through a five pin DIN analog connector. 3 electrode leads pass in the electronics box on the side opposite the cable that assigns to the interface. The sensor signal is conveyed from side to side an opto-isloation circuit. An isolation transformer is used to transfer the sensors power. Question 5 Explain in detail idea of industrial voltage to frequency converters and frequency to voltage converters using an operational amplifier. Voltage to frequency converter The voltage-to-frequency converter is a converter which delivers an output frequency precisely relative to its input voltage. The digital open-collector frequency output is well-matched through all mutual logic families. Its adding input features give the VFC32 outstanding noise resistance and small nonlinearity. Complete output frequency is determined by an exterior capacitor and resistor. Open-collector logic output is gain from the frequency output terminal. A pull-up resistor is typically connected to a 5V logic supply to generate normal logic-level pulses. Though, it connected to some power supply (+VCC). Production pulses obligate a continuous period and positive-going throughout the oneshot period. Current flowing in the open-collector output transistor proceeds by the common terminal. The terminal must be linked to logic ground. Frequency to voltage conversion The capacitive-coupled response network C3, R6 and R7 let typical 5V logic levels to activate the comparator input. The comparator causes the one-shot on the dropping control of the frequency input pulses. Beginning voltage of the comparator is about -0.7V. 5V logic levels having less waveform for frequency input, the comparator is activated by regulating the voltage divider of R6/R7 to a lower voltage. C2 smoothens the output voltage waveform. Greater values of C2 decrease the wrinkle in the output voltage. Lesser values of C2 let the output voltage to resolve quicker in response to a modification in input frequency. Resistor R1 can be pared to attain the preferred output voltage at the complete input frequency. The signal response current is equivalent to VIN/R1. This current is combined by response op amp and C2, creating a descending ramping integrator output voltage. Once the integrator output slopes to the verge of the comparator, the one-shot is activated. The 1mA reference cu rrent is swapped to the integrator input throughout the one-shot length, producing the integrator production ramp rising. Subsequently the one-shot period, the integrator again ramps descending. The fluctuation procedure forces a long-term stability of charge (or average current) between the input signal current and the reference current. Question 6 Describe the purpose and basic operation principle of differential pressure flow meters. Differentiate between orifice plate, venturi, nozzle and pitot tube. Differential pressure flow meters It is the control of fluid flow rate by interpretation the pressure loss thru a pipe restriction is possibly the greatest where usually used flow measurement method in industrialized uses (Figure 2-1). The descent of pressure created by a extensive variability of geometrical restrictions have been well considered over the years. These primary or head flow elements originate in a extensive diversity of configurations, all with exact application assets and flaws. Differences on the refrain of differential pressure (d/p) flow measurement http://www.omega.com/literature/transactions/volume4/images/07_Fig_01_l.GIF Orifice plates http://www.omega.com/literature/transactions/volume4/images/07_Fig_04_l.GIF In clean liquid, gas, and steam service, orifice plates are generally used. It is obtainable for entirely pipe sizes, very economical for gauging flows in bigger pipes (over 6 diameter). Numerous standards organizations permitted the orifice plates as is used for the supervision the transfer of liquids and gases. The orifice flow calculations used today still fluctuate from each other, though the numerous standards organizations are operational to accept a solitary, generally accepted orifice flow calculation. User can select the flow equation thru orifice sizing program. Even though it is a modest device, the orifice plate can be considered as a precision instrument. Orifice plates are fairly sensitive to a change of error-inducing situations. Precision in the drag controls, the excellence of the connection, and the state of the plate itself regulate the routine. Installation influences embrace tap position and state, form of the process pipe, capability of straight pipe innings, ga sket intrusion, misalignment of pipe and orifice drags, and lead line design. Other adverse conditions comprise the corrosion or erosion of the pipes, dirt, and grease or secondary phase deposits on either orifice surface. http://www.omega.com/literature/transactions/volume4/images/07_Fig_06_l.GIF Venture tube http://www.omega.com/literature/transactions/volume4/images/07_Fig_07_l.GIF The venturi tubes is quite expensive, so they are mainly used for greater flows or on further tough or difficult flow applications. Venturis are not sensitive to velocity outline properties and consequently need fewer straight pipe run than an orifice. The character of scrubbing act of the flow through the tube creates the device resistant to corrosion, erosion, and interior scale build up. Due to high initial cost, the owner still is promising as the savings in fitting and functioning and maintenance costs. Flow element is long which considered by a narrowing inlet and a deviating outlet. The entrance is used to determine the inlet pressure, while the throat section is to measure the static pressure. The pressure taps nourish into a joint annular chamber, as long as an average pressure analysis over the whole perimeter of the element. The venturi is partial in its use to clean, non-corrosive liquids and gases. The great instability and the absence of holes in which material can gath er create flow tubes well suitable for slurry and mud services. But, maintenance costs can be high if air removal cant stop persisting of the pressure taps and lead lines. Plunger-like devices (vent cleaners) can be connected to occasionally eliminate accumulation from interior openings, even though the meter is online. Flow nozzle http://www.omega.com/literature/transactions/volume4/images/07_Fig_09_l.GIF The flow nozzle can be said it is more stable than the orifice plate, mainly in greater or higher temperature and higher velocity services as compared to orifice plates. It used to determine high flow rates of superheated vapor. The flow nozzle also having a better flow capacity than the orifice plate and needs a lesser first investment than a venturi tube, but also delivers lesser pressure recovery. A main disadvantage of the nozzle is that it is harder to change than the orifice except it can be detached as part of a spool unit. Flow nozzles preserve their accuracy for long periods, even in tough service. Flow nozzles can be very accurate way to determine gas flows. As soon as the gas velocity influences the speed of sound in the throat, the velocity cant surge any more and a overcome flow condition is extended. Pitot Tubes http://www.omega.com/literature/transactions/volume4/images/07_Fig.12_l.GIF Pitot tube is one of the simple in design flow sensors where it is used to measure varied range of flow measurement applications. Normally, it is used in air speed in racing cars and air force fighter jets. Pitot tubes also used to analyze air flow in pipes, ducts, and stacks, and liquid flow in pipes, weirs, and open channels in industrial applications. The accuracy and range capability are moderately low, while pitot tubes are modest, dependable, low-cost, and suitable for a diversity of environmental situations, plus tremendously high temperatures and a wide range of pressures.
