Running head: PURSUING CLEAN ENERGY OPTIONS 1 Pursuing Clean Energy Options Gwynedd Mercy University SCI 2000: From Telescope to Microscope Thomas Becker PURSUING CLEAN ENERGY OPTIONS 2 Abstract In this document, the intent is to give an overview at the viability and emphasis on clean energy. There are five different venues of alternate energy sources, being thatÃ¢â¬ ¦show more contentÃ¢â¬ ¦Fossil fuels, with their extreme CO2 discharges and our unfortunate dependence on them, are still stimulating experts of better alternatives in focusing their efforts on clean energy. PURSUING CLEAN ENERGY OPTIONS 3 First of all, our country has experienced the decline of our natural resources, like tragic forest fires, the pollution of our water supply and damaging air pollution, not to mention food contamination. Anyone with any intelligence can overlook our growing environmental epidemic. Some people may not be aware of the severity of the problem, but most would agree that our communities need to be protected and preserved. This is why now scientists, financial advisors and economists are mutually concerned by the obvious dilemma in recognizing that our society is changing and needs to be redirected into a more stable, healthy and sustainable direction. There are the ignorant amongst us who placing all their attention on the economy, money and the job market while in observing the daily rise and fall of the ever changing stock market. It almost appears that they turn a blind eye of the inevitable energy crises. What should be all of our focus is how do we address our depleting ene rgy options? How theses growing limitations are looming over our head could affect our future prosperity and health. Maybe there is more concern than it appears where the expert

the Love Song of J. Alfred Prufrock launched T.S. EliotÃ¢â¬â¢s status as the influential poet of the twentieth century. The poem narrates the self-analysis of a man, Prufrock, who exposes the void and soulless quality of the modern world through his experiences. The morbid outlook of his life stems from his inability to find meaning in his existence. He is entrapped in a constant cycle of overwhelmingly negative emotions -- anxiety, hopelessness, and despair -- haunted by his fears and regrets. PrufrockÃ¢â¬â¢s thwarted desires and representation of a broken society both epitomizes the common frustrations of the modern individual and exemplifies the qualities of modernism. Modernist writings often portray a disorderly world that lacks meaning through fragmentations in form, meter, and images. PrufrockÃ¢â¬â¢s series of fractured encounters are better illustrated by EliotÃ¢â¬â¢s approach to imagery. Through images, Eliot creates a precise visualization of PrufrockÃ¢â¬â¢s Ã¢â¬ Å"disparate experiencesÃ¢â¬ that engages with readersÃ¢â¬â¢ physical senses. Despite PrufrockÃ¢â¬â¢s conflicting train of thoughts, Eliot astutely amalgamates them into Ã¢â¬Å"new wholesÃ¢â¬ to better portray PrufrockÃ¢â¬â¢s character and present the notion that meaning can be excavated from the ruins. Eliot tends to impose specific meanings onto the images in his poems. In his essay Tradition and the Individual Talent, we are able to better decipher the meanings as Eliot explains his approach on imagery.

Error Analysis Lab By: Lab Team 5 Introduction and Background: In the process of learning about the importance of measurement and data processing, lab teams were given prompts to design experiments as well as address the precision, accuracy, and error analysis within the experiment. Lab teams collaborated their data to find similarities and differences within their measurements. Through this process, students learned the importance of the amount of uncertainty as well as the different types of experimental errors that might have caused a margin of difference within the lab teams results. We will write a custom essay sample on Error Analysis Lab or any similar topic only for you Order Now Measurement and data processing is a topic discussed in IB Chemistry SL; it is important within the scientific community as it discusses the reliability of the data presented. Uncertainty is used to determine a range of a value in a measurement or instrument. Uncertainty of an analogue instrument is plus or minus half of the smallest division present; while uncertainty of a digital scale is plus or minus the smallest division present. To identify the amount of uncertainty, significant figures (the digits in measurement up to and including the first uncertain digit) are used. Certain rules are used to discover the number of significant figures in a value: * 1-9 are always significant * included zeroes (1009= 4 significant figures) * leading zeroes never count (0. 023= 2 significant figures) * trailing zeroes after the decimal count (1. 9850= 5 significant figures) Experimental errors are the difference between recorded value and generally accepted or literature value. There are two types of experimental errors: random and systematic errors. Random errors are caused by the readability of a measuring instrument, the effects of changes in the surroundings, insufficient data, and observer misinterpretation. Systematic errors are errors that can not be reduced by repeating experiments or careful experimental design. These errors are caused by poor experimental design as well as improper measurement techniques. Accuracy is the difference between the experimental value and the accepted value. The greater the accuracy, the smaller the systematic error. Precision is the reproducibility of the experimental value. The greater precision, the less the random uncertainties. Purpose: Design laboratories based upon ideas of accuracy, precision and error analysis through creating a procedure and addressing the prompts. Materials: * 13. 5 cm x 10 cm sheet of aluminum foil * Ruler * Balance * Laptop * Micrometer * Silver Cube of Unknown Solid * H2O (via sink) * Timer * Thermometer (in degrees Celsius) * 500 sheets of paper * Caliper * 100 mL graduated cylinder * 10 mL graduated cylinder * 25 mL flask Procedures and Methodologies: Station One (find volume, mass, and density of an unknown cube): 1 Find the height of the silver cube of unknown solid using the micrometer. 2 Find the length of the silver cube of unknown solid using the micrometer. 3 Find the width of the silver cube of unknown solid using the micrometer. Find the mass of the silver cube of unknown solid using the balance. 5 Using the measured length, width and height of the cube of unknown solid, calculate the volume of the cube. 6 Divide the mass of the cube by the volume to find the density of the cube. 7 Using the laptop, identify the type of metal based on the density. Station Two (find a way to measure 10. 5mL of water): 1 Using the 10 mL graduated cylinder, measure out 10 mL of water. 2 Pour the measured water into the 100 mL graduated cylinder. 3 Using the 10 mL graduated cylinder, measure 0. 5 mL of water. Pour the measured water into the 100 mL graduated cylinder, combining with the previously measured 10 mL of water. Station Three (measure the thickness of single sheet of paper and volume of 500 sheets): 1 Measure the height of the stack of paper with the ruler in millimeters (mm). 2 Measure the length of the stack of paper with the ruler in mm. 3 Measure the width of the stack of paper with the ruler in mm. 4 Calculate the volume of the stack of paper using the rulerÃ¢â¬â¢s dimensions in millimeters. 5 Calculate the thickness of one sheet of paper based on the rulerÃ¢â¬â¢s dimensions. Divide the height by number of sheets of paper [500 sheets]). 6 Repeat steps 1-5, instead using the caliper for measurements, but still measuring in millimeters. Station Four (calculate the volume of metal cylinder): 1 U sing the caliper, measure the height of the cylinder in millimeters. 2 Using the caliper, measure the diameter of the cylinderÃ¢â¬â¢s circle in millimeters. 3 Using the volume of a cylinder formula (pi x radius squared x height), calculate the volume of the cylinder. Station Five (Calculate the thickness of aluminum foil): 1 Using a laptop, determine the accepted density for aluminum. Using the electronic balance, measure the mass of the sheet of aluminum foil. 3 Divide the mass by the accepted density to determine the volume. 4 Using the ruler, measure the dimensions (length x width) of the sheet of aluminium. 5 Divide the volume by the dimensions of the aluminum to determine the thickness. Station Six (Measure the temperature of the sink water for 120 seconds): 1 Turn hot water knob on. 2 Hold thermometer under running water. 3 Record temperature at 60 seconds. 4 Record temperature at 90 seconds. 5 Record temperature at 120 seconds. 6 Remove thermometer from water. Station Seven (Determine the circumference, density, and identity of wire): 1 Using the micrometer, find the diameter of the of the wire 2 Multiply the diameter by pi (3. 14) to find the circumference of the wire 3 Using the ruler, find the length of the wire 4 Using the balance, find the mass of the wire 5 Multiply the circumference and the height of the wire to determine the volume 6 Divide mass by volume, to determine the density of the wire. 7 Using the laptop, identify the type of metal based on the density Data Collection: Station One- The results from measuring the volume, mass, and density of a unknown cube .

While the mass and density were rather close in value, there was no close range in the measurement of the volume of the unknown cube. This can be seen in the graphs below. Some random errors that may have caused this lack of precision in finding the volume of the unknown cube are misreadings of the instruments, changes in the environment of the experiment, the number of significant figures used, and the experimenter approximating a reading. Station 2 (find a way to measure 10. 5mL of water) In this station, there were two identifies outliers. This included Group 2 and Group 3. They were identified as outliers because of the amount of uncertainty. This two groups had a rather small amount of uncertainty unlike the other four groups with identical amounts of uncertainty. This can be seen in the graph below. The error that would have caused the amount of uncertainty is systematic because water will have clinged to the sides of the graduated cylinder as it was emptying. Another reason it was a systematic error was the fact that too much water could have been added to the graduated cylinder as it was filled. Station 3 There is only one large outlier within this station. In measuring the volume, Group 2 measured the volume to be 6. 0 cm3 while all other groups said the volume was around 3000cm3. This is such a huge gap that it would not be counted as a valuable measurement. Errors that could have occurred in this lab could have been random like the mismeasurement of the volume. The error could have also occurred by the misinterpretation of the question or prompt given. Station 4 The outlier in this station is group 3 with a Station 5 Station 6 Station 7 Conclusion and Evaluation: In result of the preformed lab, our team learned the importance of determining error as well as preventing the majority of this error. The large range of results most likely was a result of systematic error. This can be concluded because there were no set directions for each station, and a different procedure could have been used by each lab team. Another source of error can be seen in the difference in sig figs used between groups. Random error most likely was a result of the unfamiliar tools that were used for the first time by many students. How to cite Error Analysis Lab, Essay examples

Prove cathartic Paper Aristotle wrote in Poetics that tragedy should contain incidents arousing pity and fear and thus prove cathartic for an audience. To what extent does the plot of Arthur Millers play, All My Sons allow for this? Arthur Miller (1915-2005) in All My Sons (1947), journeys the key concept of catharsis through the intricate character of Joe Keller; our tragic hero and his hubris flaw, the concept of Hamartia, the generating of pathos through language and most importantly the formula of tragedy, described by Aristotle, bringing about catharsis. All My Sons starts at the end of summer in suburban America, after World War Two. The events of the play, described by Miller, occur on a single set, the backyard of the Keller home, a secluded atmosphere, considerably the American Dream. Furthermore there stands the stump of an apple tree, as its trunk and branches lie toppled beside it1. Miller here, emotionally engages us into the play with the use of pathetic fallacy, increasing our emotions by building tension and giving opportunity to the futures of tragedy. The audience no longer feel safe behind the American Dream but instead are presented with a faade of respect, somewhere much sinister , preparing the audience for the upcoming tragedy. Miller uses this same technique again when Joe Keller, our protagonist, notifies: Gonna rain tonight. 2 Miller builds fear in the audience, suggesting something unpleasant about to happen. Nevertheless as the audience learn more about Joe Keller, we see that he is an ego-centric man, whose mental attitude does not go beyond his own sphere. Where society is dysfunctional, Kellers choice simply remains to ignore them and their changing platforms: heres a guy is lookin for two Newfoundland dogs. Now whats he want with two Newfoundland dogs? .

Perhaps different audiences react differently to Keller as a character. It is debatable that Keller does not understand the subtleties of life because he is lazy, selfish and his outlook is materialistic, therefore perchance building exasperation in the audience and receiving no compassion. Or perhaps as an audience we become harsh and forget to realise that Joe Keller is financially comfortable. But beyond this the audience still pity Kellers inertia as he struggles to move on. Similarly Kate Keller cannot move beyond the inertia she is trapped within. She is in denial about Larrys death which has driven her to spirituality, her emotional crutch: Hes not dead, so theres no argument! 4 This makes the audience pity her sub-conscious state and empathise with her hope for Larrys return. It could be argued as to what extent we can cope with her denial and her rejection of reality. Progression sees Miller introduce us to the bliss of hope, this is important to the cathartic journey, as we hope for some re-alignment of morality or achievement of justice. Hope is first presented through Frank Lubey, a superstitious character, who brings us closer towards catharsis through the melancholic life he lives and the hope he brings within the play for fellow characters, besides the hope the audience already bear: (Looks up at the sky) These stage directions are evidence of Franks hope and transcendence into a world of his own. Nevertheless, Chris Keller is a warm man who cares for his father and becomes Millers mouthpiece in demonstrating the world beyond the Keller home. He strives for independence and security but constantly gets held back from his parents and is put into an inertia of his own: every time I reach out for something I want, I have to pull back because other people will suffer. 5 This is part of Millers plot where pathos allows the audience to feel emotions of pity evoked by Chriss helplessness and thus prove cathartic. The audience also fear as to what step Chris might take in the future because of his suffering: Ill get out. Ill get married and live some place else. Maybe in New York. 6 The audience also empathise with Chris, as the family secret prevents him from breaking free and therefore the audience hope for Chris life to be re-aligned and end happily with his marriage to Ann. However this news arouses trepidation in the audience and characters because they do not understand as to how Kate might react because of her fragile state and her stubborn will. This is evident through Kellers dialogue and Millers apprehensive language: Well, you want to be sure Mother isnt going to -7. At the very end of Act One the audience are left feeling a strong sense of fear for Joe Keller when he is made aware of George Deevers return. The audience understand Kellers vulnerability and his lack in understanding the complexities of life therefore he sees no harm in Georges return, but is it debateable as to whether Keller might know how much of a risk it could be on a sub-conscious level and as to what George might be here for? Miller has made this is evident through the stage directions, exemplifying the fear: (frightened, but angry): Yes, Im sure. The fear left with the audience to experience at the end of Act One becomes pivotal in the role of experiencing catharsis. Miller has instantaneously given us the opportunity to empathise with the characters and in turn fear for them thus we are given a sense of foreboding, vital for ultimately experiencing catharsis in any tragedy. In the opening stage directions of Act Two Miller, again, uses pathetic fallacy to suggest the progression in the plot and perhaps the catastrophe still to come suggested metaphorically by Miller: leaving stump standing alone 9 Though as the play progresses a growing sense of anxiety is created in the audience by Miller. We can see this through Sue Bayliss a character chosen by Miller to represent the wider community. This lets the audience fear even more for Joe Keller as a character because it becomes apparent that not everybody overlooks his guilt: Theres not a person on the block who doesnt know the truth. 10 In Act Two Miller finally decides to present a rush of emotions which soon psychologically engage the audience as well as the characters Chris, Ann and George. Millers use of short, forceful sentences build tension and anxiety in the audience that we soon become eager to reach some sort of resolution, where inner peace can be found. This is witnessed through Georges dialogue and we soon learn to identify with Georges character because we recognize his impatience to reach a cathartic ending: But the morning passed. No sign of Joe. So Dad called again. 11 Georges transcendental state also suggests trouble constructing an impression of fear upon the audience: (Calling as George pays no attention ). Considering Georges character we could deduce that he is a caricature used by Miller to start the tragedy and thus the journey to catharsis. After the anxiety we experience, Kates sudden entrance to the involvement of catharsis builds tension and hope for resolution. But then Miller entraps us into a network of terror once more when Kate slips her tongue disproving Kellers alibi, this brings hope for Chris and George as we, the audience, hope that they will find out the truth and move on out of the inertia: He hasnt been laid up in fifteen years.

Air Pollution in Almaty Essays Air Pollution in Almaty Paper Air Pollution in Almaty Paper who gave Very different answers. In the beginning of the survey, the Interviewers elicited from the respondent information about their driving habits and their vehicles as well as the degree to which air pollution bothers them. Then it was necessary to convey to the respondent a great deal of information about the pollution fees: information about the features of the basic plan, such as the technology and uses of the revenues. In order to keep the respondent engaged in the interview process, resented this information to respondents in questions of the form, Suppose dirty cars paid a higher rate than cleaner cars. Would you be more or less likely to support the fee policy? Structured interview were carried out to gain a more qualitative picture of the current situation of the transport system and air conditions in the city. The results of the questionnaires are presented first, followed by the quantitative results of the structured interview. Questionnaires were distributed among 20 students from SKIMP, who have cars, from September 25th to October 14th. Ten of the participants are male ND ten are female. All participants ranged from 18-22 years in age. In the survey there were 6 closed questions with multiple choice answers, but to know the individual approach of the person I made the last choice as your answer to the most questions. So the first question was: Are you satisfied with the condition of air in Alma? 63 % of students answered that they were not satisfied, while the rest answered yes. This proves that most Of people recognize their home air quality problems. The second question was about what is the major cause of air pollution in Alma. The majority of exponents (78%) agreed that vehicles contribute to pollution and that vehicle emissions are harmful to human health. The third question was: Do you see any success in implementation of transport programs to reduce air pollution in the city? Opinions were divided equally. Less than 50 percent agreed, but 54 percent of students claimed that the entire available budget didnt return to the public. The fourth question was about the cause of failure of these programs. Approximately 52% do not believe that taxes are spent wisely, 30% of respondents considered that the cause of this were corruption r stealing government money by civil servants, and 18 % of respondents answered that they did not think about it before and they do not care about it . The fifth question: M/hat must be done to make the ecological situation of Alma better? There must be much more green plants in the city (36%). The number of cars must be reduced (24%). The traffic must be limited (20%) We can do nothing already (13%). O not know (7%). The sixth question, can you use public transport as an alternative to using private car? 87% of students said no, the rest yes. It is obvious that there are no good alternatives to using ears. People are selfish and for them comfort comes above all else. However for the same question but with addition point, the results of answers were definitely different. Can you use pu blic transport as an alternative to using a private car? (if government improves the condition of public transport, and the prices increase, because of the cost of changes in quality) 72 % answered no, the rest responded yes. As internet makes our life easier to communicate, I conducted the flogger interview by asking questions related to my topic to Alma Deputy Akin (Mayor) Victor Telephoned. Victor Telephoned is a Deputy Akin of Alma since April 2008. He is at age 63 and has 44 years of work experience in building and construction management. First of all, I sent him a letter where I introduced myself and briefly explained my reason for writing. Then I asked interesting questions related to my topic. The office of Deputy Mayor quickly sent some answers to my questions. However in my opinion answers were quite formal. The first question was concerning the increasing number of cars in the city. There are currently more than 500,000 vehicles registered in Alma. What actions have been ken by local authorities to reduce this number? Doltishness answer was that on 1 July 201 1 the government of Astrakhan established preferential tariffs on the import of cars by individuals for personal use. In other words, the new law indicates that taxes on import cars have been increased. And certainly it leads to decreasing number of import cars. Then interviewee answered on the second question that was about new transport programs in Alma. Telephoned responded that they strengthened control over the quality of motor fuel, emission standards and technical inspection of vehicles ND improved transport infrastructure to reduce automobiles burden on the city. He stated : In the last 3 years alone, 7 new interchanges, tunnels, and the first section of Eastern bypass were built. And works in these directions will continue. When Telephoned was asked a question about the quality of air in the city, he explained that they plan to purchase 200 modern trolleybuses, launch a large-scale project on creation of light rail system through a mechanism of state- private partnership. In addition, the interviewee showed his strong position in favor of using natural gas by transport vehicles: There are 200 uses working on compressed natural gas, 50 of which serve the city routes have been already purchased. After this response, I was most concerned about the use of natural gas instead of diesel fuel. So the next question was how they plan to implement this transport strategy. The mayor explained that the mayors office intends to economically encourage owners Of private cars to use natural gas. He stated: Legal persons, buying gas instead of diesel fuel pay half less. One can count himself: the cost of using gas is 14. 85 tinge per one km. At the same time at using diesel fuel one has to pay 24. 4 tinge, and 29 tinge if your car works on gasoline. Obviously, the natural gas has advantage. However Alma has a weak transport policy which favors automobiles rather than public transport. And it is clear that if people used their cars less this would help to prevent the greenhouse effect. So the next question I asked the deputy akin was when conditions of the public transport will improve. Because it is no secret how many problems drivers of private passenger vehicles make on the roads. In addition, there are still a lot of complaints about the quality of passenger service, rude inductors and the unsightly appearance of the buses. On this question the mayor claims that Traffic Police Department of Internal Affairs regularly conduct raids to detect and prevent violations of passengers and traffic rules by drivers of public transport. By finding facts police impose administrative fines, and not only for drivers but also for managers and executives of enterprises and carriers. Road safety engineering courses and customer service trainings are held daily with the drivers of public transport in the city. In conclusion, despite intense regulatory efforts to reduce vehicle emissions ever the past twenty years, emissions from vehicles continue to be major source of air pollution problems in the financial capital of Astrakhan. By surveying local people from Alma about vehicle pollution, it was clear that people who have become too reliant on cars can cause many problems. Moreover, what Object to is that the view Of Deputy Mayor about success the implementation of transport strategies particularly does not coincide with opinions of students. However, it is important to mention that the levels of us port transport strategies by students were significantly affected by the design features of plans. The survey results clearly indicate that good structured transport strategies and introducing pollution fees on motor vehicles in Alma can attract majority public support. The results also indicate where support and opposition to these plans may be found to aid in targeting publicity and informational campaigns. Finally, I think examination of these statistical results may be useful in the development of pollution fee programs to present to the public. Chapter 5 Conclusion The main objectives Of this project were to discover the causes Of a weak transport policy in Alma. As was described in survey chapter, research indicates that urban planning is a new trend in city programmer, which will help to develop Alma as a multicultural city and thus to reduce travel distance. These programmer also include buses working on gas and blouses. However, there is a concern over whether the political power will be strong enough to implement this long term task. By surveying local people from Alma about vehicles pollution, it was clear that people became too reliant on car that can cause many problems. Moreover, the view of Deputy Mayor about success implementation of transport strategies particularly does not coincide with opinions of students. However, it is important to mention that the levels of support transport strategies by students were significantly affected by the design features of plans. Reading different articles found out that road pricing is an essential part of any solution. Take for example case in London, congestion charging was introduced in order to reduce traffic congestion, and despite some weaknesses and high costs the scheme has achieved its main targets reduce of air pollution. Second solution is the development of strong public transport as an alternative travel mode to the car. And third solution is investment of all venues from the pricing scheme in the transport sector. However, Alma is an city from developing economy, the implementation of road pricing in a city with poor public transport and a bureaucratic and ineffective taxation policy would not bring desirable effects in congestion and urban pollution reduction problems. Therefore all we need to do to reduce the problem is simply to be less wasteful. People can make less air pollution just by doing every day small things like drive less, more walk or use the bike. One can say it will definitely improve the protection of the environment as well as human health.

How to Make a Sparkler - Easy Homemade Firework Sparklers are a handheld fireworks that dont explode (pyrotechnic devices). They are easy to make, plus you can use your knowledge of chemistry to make colored sparks. Difficulty: Average Time Required: minutes to make, several hours drying time What You Need to Make a Sparkler Iron wires or wooden sticks300 parts potassium chlorateÃ 60 parts aluminum fines, flitter, or granules2 parts charcoal10% dextrin in water solution500 parts strontium nitrate (optional, for red color)60 parts barium nitrate (optional, for green color) How to Make the Homemade Sparkler Mix the dry ingredients with enough dextrin solution to make a moist slurry. Include the strontium nitrate if you want a red sparkler or the barium nitrate if you want a green sparkler.Dip the wires or sticks in the sparkler mixture. Be sure to leave enough uncoated space at one end to safely grasp the finished sparkler.Allow the mixture to dry completely before igniting the sparkler.Store sparklers away from heat or flame, and protected from high humidity. Tips Parts are by weight.Be certain the sparkler is out and cooled before discarding it. This is easily accomplished by dipping the stick in a bucket of water.Firework use is restricted or prohibited in some areas. Please check your local laws before igniting homemade or purchased sparklers. SourceÃ is L.P.

Atrial Fibrillation - Article Example Possible causes that give rise to AF include comorbidities like hypertension, coronary ischemia, heart failure and obstructive sleep apnoea. The characteristic features of electrical remodelling are alterations in atrial refractoriness, atrial conduction and sinus node function. This happens very quickly and is considered possible to reverse. Loss of contractility results from the contractile remodelling that happens in AF and like electrical remodelling happens very quickly. Reduction in the release of systolic calcium ions is believed to contribute to this change. Myolysis or the loss of sarcomeres is also a likely candidate for this change. The consequences of contractile remodelling are thrombus formation and atrial dilation. Advance of AF may be caused by contractile remodelling through the coexistence of multiple wavelets. Reversing contractility changes takes longer than in the case of reversing electrical remodelling changes possible because of the time involved in the replacement of lost sarcomeres. Persistent AF has been associated with the structural changes within the atria. Many of these changes are consider ed to be irreversible. Evidence from animal studies suggests that these changes occur more slowly than the changes that occur from electrical and contractile remodelling and primarily reflect dedifferentiation. The striking changes seen in animal models are increased cell size, myolysis, and the collection of glycogen around the nucleus of the cell. From the limited data from humans there is indication that degenerative changes may occur (Cohen & Naccarelli, 2008). Management of AF is a three pronged strategy. The first is of the prongs is anticoagulation. Use of anticoagulation is guided by the CHAD scoring system set forth by the American College of Cardiology, American Heart Association, and the European Society of cardiology. When the AF patient has any one of these
