Childhood Obesity in America Essay Example | Topics and Well Written Essays - 1000 words

Childhood Obesity in America - Essay Example To encourage healthy lifestyles among the American children, there is a need to have collaboration between parents and the education system to encourage healthy lifestyle among children though physical education and healthy diets in addition to the government introducing regulations on marketing of food meant for children consumption. Parents are the greatest contributors in childhood obesity due to their failure to control their children’s eating habits and engagement in physical activities. According to Parizkova and Hills, parents in modern US society have a tendency to prefer eating fast food in restaurants to cooking food at home while also allowing too much television watching by encouraging practices such as having bedroom televisions (396). It is important that parents encourage a healthy lifestyle for their children by cooking for them healthy meals at home. Cooking at home will ensure parents serve their children a balanced diet in addition to having enough portions per sitting. Additionally, limiting the number of hours children spent watching television will encourage other pass time activities such as outdoor games that are more physically engaging. Some people argue that parents can still acquire healthy meals in the restaurants by asking for healthy portions. Although this is partly true, pa rents can exercise more control over what their children consume by taking part in choosing ingredients as well as the process of cooking meals when it is done at home as opposed to in a restaurant. Therefore, preparing food at home becomes the best option when parents want their children to have a balance diet. The high level of childhood obesity in the US is not only as a result of a failure by parents to control the lifestyle of their children, it is also a failure of the education system to teach them about healthy living.

Why College Students in Metro Manila Take Up Part-Time Jobs Essay Example for Free

Why College Students in Metro Manila Take Up Part-Time Jobs Essay A part-time job is a form of labour where in one works fewer hours per week than that of someone who works at a full time job. Those who have part-time jobs work for less than thirty to thirty-five hours a week. May it be capable, post-graduate adults or under-aged students, the amount of people with part time jobs have increased over the past 20 years in most developed countries. â€Å"There are many reasons for working part time, including the desire to do so, having ones hours cut back by an employer and being unable to find a full-time job. † [] Many students work part time jobs to supply themselves with additional funds. Working part-time is ideal for students, since it allows them to balance their academic needs with their school needs. This is one of the things some students in High School look forward to when they graduate and step up to college, to have freedom and a preview of the world that is waiting for them once they graduate. They want a peek of the â€Å"real world† as some say, which is the world of adults, the working world. Though some are forced to go through with this as their economic status demands it, there are still many advantages when it comes to taking up part-time jobs. Collegiate students are given a bigger work load than any other department but many still go through with it despite their amount of tasks. It is because for many hardworking students, like ones who had graduated with many honours, it looks good on a resume. The employers usually see this as a good thing for they know that their candidate for employment can handle a large amount of work properly. With a good looking resume, it would not be that hard to get a job. Moreover, parents would like to give their children a sense of responsibility in which they tell their children to apply for part time jobs so as to let them experience what it feels like to have their own money to budget. Statement of the Problem This study aims to analyze the reasons why college students take up part time  jobs and how they manage their time. In a more detailed manner, it is to answer the following questions: 1. What are the reasons college students take up part time jobs? a. Is it an absolute necessity? 2. How much do they earn per week? 3. On what do they spend their money on? 4. Do they give part of their payment to their parents? a. How many percent? 5. Are they able to manage their time? a. How many hours a day do they work? b. Do they have other activities/responsibilities? 6. What motivates them to keep working? a. Who gave them the idea of applying for their jobs they have? 7. How long have they been working? Scope and Limitations The topic is about collegiate students with part time jobs. The study will be conducted to know how students of different schools in the collegiate department juggle their studies with part time jobs. The study will tell about how they cope with the sudden change in their habits and their time management. The study will also tackle the reasons why they took up their current jobs, if the job is a necessity or if it is of their own desire. The study is time pressured. The time to work on the study is seven months. The respondents will be various students of a few different colleges around the Cavite and Metro Manila area, School Year 2012-2013, who have a job that requires them to work for less than 39 hours a week. Significance of the Study The study is important to many current and upcoming fourth year students who are planning to take up a part time job in their collegiate years. It would help them to further understand the advantages and disadvantages of what they are hoping to get themselves into. This research will help them be sure of what they want. This would also help them find a way to manage their time once they are there. The study would also help the students already in college. It would help those with part time jobs feel easier knowing other people go through the same things they do. The study will also help them manage their time better. It would also help those collegiate students who do not have jobs. It would give them a better view. The study will give them a good, first person point of view insight. Furthermore, this study would also help teachers and parents to understand the stress and pressure the collegiate students with part time jobs go through. This study will open doors for them to be able to create a stronger family bond. Research Design 8. What are the reasons college students take up part time jobs? 9.

What is Philosophy? :: essays research papers

What is Philosophy?   Ã‚  Ã‚  Ã‚  Ã‚  I believe that Philosophy is the study of different ways of thinking. In philosophy, you should question everything and never take anything for face value. There are always two sides to every coin as there are different ways of looking at things, is what philosophy teaches us. In philosophy, you must throw off all the limitations you have set on yourself when dealing with how you view things and how things seem to be.   Ã‚  Ã‚  Ã‚  Ã‚  Reality is a big topic of discussion in philosophy. How you view things may not be how they really are. A schitzophrenicÕs reality is different from the reality of a Ã’saneÓ persons. Therefore I deem reality to be based on experiences, and perceptions. Something you deem to be wrong may be the same thing your friend deems to be right. So does this mean that there really is no one true reality?   Ã‚  Ã‚  Ã‚  Ã‚  In Philosophy, we learn that it is okay to doubt things that occur in our lives. It is not only okay but it is a natural response to something you are unclear or uncertain about. Sometimes, though, the build-up of doubt becomes too much for someone to handle so they become suicidal or just give up trying to think about it all together. When this happens, there is a tendency to become cynical, and this is a tragedy because then you feel like nothing is really worth trying to figure out.   Ã‚  Ã‚  Ã‚  Ã‚  Most of philosophy deals with the Ã’selfÓ. People are always trying to find out who they are; why theyÕre here; or how things relate to them. All of our lives are spent on a road of self discovery, seeing what the world has to offer us, and where our place really is. If we were to actually look closely, we would see that   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  page 2 we knew who we were all along, we just didnÕt realize it.

Martin Luther ; Henry VIII

The Catholic Church has begun to sell indulgences, a way to pay off sins to reduce time in purgatory, to raise money. A monk who is outraged by the pope tricking innocent worshipers into falling for his trap writes down a list of 95 reasons why the church has become corrupt by the light of a scroll and furiously hammers them to the door ofa German church. Meanwhile in England, a king is denied an annulment to his marriage.In a fit of anger, he removes the church's uthority and writes up his own religion for his land and people, with himself as to rule. A monk and a king; Martin Luther and King Henry VIII; two souls of polar opposites who broadened Europe's worldviews of religion with their gifts of Protestantism and the Anglican Church. Martin Luther, born in Germany in 1483, was a man of logic: he studied law, as guided by his father, but longed to learn about religion. One night in 1505, he was caught in a horrid lightning storm. He prayed to God, promising to become a monk if he l eft this storm alive and unharmed.He followed his word and taught peacefully. However, in 1 516, one of the catholic pope's commissioners was sent to Germany to sell and collect indulgences. This angered Luther because many of his people stopped attending church services, believing that since they had paid off indulgences, they had no need to ask forgiveness within the pews. He thought that since they would do this that they instead would spend more of an eternity in purgatory. On October 31, 1517, he began to write the 95 Theses, a list of reasons why the Catholic Church was corrupt in their intentions.He posted these onto the oor of his church with the intended audience to Just be the priest and a few others. However, because of the invention of the Printing Press, copies of Luther's works were printed and spread across Germany- eventually Europe and into the hands of the pope. People related to Luther's thoughts and this began Protestantism. Luther's journey wasn't over for him y et, though. After numerous warnings from the pope to take back what he had said, Pope Leo X excommunicated him in 1920. In 1521, Luther was called by a council of people, known as the Diet of Worms, for him to be tried as heretic.When he continued to stand by his word, he was declared an outlaw and went into hiding once returning to Germany. Meanwhile across the pond, Henry VIII had problems of his own. After taking the throne and marrying his brother's wife, he had the dilemma of being unable to have a son produced between them. Henry turned to the Pope for a marriage annulment, but was denied ofa divorce. Henry didn't want to hear ‘no' for an answer, so he called forth the Reformation Parliament to declare England to be no longer under the control of the Pope.The Acts of Parliament closed down the monasteries and put Henry in charge of the church, which was known as the Anglican Church. Out of his took the throne, Protestantism began to take root. It was not until when Henry s daughter, Mary, took the throne that England was returned to the Pope's authority. Luther never wanted to start a war against the church; he Just wanted them to let him and his beliefs in. In contrast, Henry wanted to show the church that he had the power and could do what he wanted.Henry desired to have a new church to control or his desires while Luther only wanted to help change the church (though this did not go in his favor). The Protestant Reformation combined both Luther and Henry VIII's works as well as other scholars. In the end, Europe, and even the world, would never be the same if it weren't for Martin Luther and Henry VIII making adaptions on their own. Without the Catholic Church putting up the walls for Henry or tainting the public to Luther, we would never have such diffusion between religions and cultures to add variety to our ancestors' everyday lives and ours.

Journal on Chapter One of Al Gore’s “The Assault on Reason” Essay

In the first chapter titled Politics of Fear of Al Gore’s Book, â€Å"The Assault on Reason,† the author basically dealt with one of the most prominent human emotions— fear. According to Gore, fear is the prime enemy of reason. When a person experiences fear of something or someone, his or her reasoning ability is shut down. In addition, Gore claims that fear also clouds a person’s judgment as it drives him or her to act recklessly or irrationally without considering all options available. Furthermore, Gore also pointed out in his book that fear does not only affect a single individual, but an entire nation as well. According to him, a nation crippled by fear is unable to act towards development and progress because it does not do anything to overcome that fear. On the other hand, based on Gore’s book, when a person views fear as a form of motivation for him or her, he or she would eventually act to overcome that fear and accomplish his or her goal. Generally, I agree with most of the arguments that Gore pointed out in the first chapter of his book, particularly on the areas where he related fear to politics. I believe that Gore was right in saying that there are times when people fail to distinguish between the illusionary fears and the legitimate or real ones. When this happens, people may find it extremely difficult to think rationally and plan their next move because their judgment is clouded and they are unable to listen to reason.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Furthermore, I also believe that Gore was correct when he claimed that the present administration in the United States as used the people’s fear, which spawned after the September 11 terrorist attacks in 2001, to manipulate various political processes and made people believe that   all Iraqi’s were the one’s responsible for the attacks. For me, I believe that it is wrong to think all Iraqis or Muslims are terrorists simply because their fellowmen may have committed heinous crimes. I believe this is the best example of the fear that has been plaguing US citizens since the 9/11 attacks. I also believe that the nation should first identify which fear is legitimate and which is not before exercising judgment.

History of Feral Rabbits in Australia

History of Feral Rabbits in Australia Rabbits are an invasive species that has caused immense ecological devastation to the continent of Australia for over 150 years. They procreate with uncontrollable velocity, consume cropland like locusts, and contribute significantly to soil erosion. Although some of the governments rabbit eradication methods have been successful in controlling their spread, the overall rabbit population in Australia is still well beyond sustainable means. History of Rabbits in Australia In 1859, a man named Thomas Austin, a landowner in Winchelsea, Victoria imported 24 wild rabbits from England and released them into the wild for sport hunting. Within a number of years, those 24 rabbits multiplied into millions. By the 1920s, less than 70 years since its introduction, the rabbit population in Australia ballooned to an estimated 10 billion, reproducing at a rate of 18 to 30 per single female rabbit per year. The rabbits started to migrate across Australia at a rate of 80 miles a year. After destroying two million acres of Victorias floral lands, they traversed across the states of New South Wales, South Australia, and Queensland. By 1890, rabbits were spotted all the way in Western Australia. Australia is an ideal location for the prolific rabbit. The winters are mild, so they are able to breed nearly year-round. There is an abundance of land with limited industrial development. Natural low vegetation provides them with shelter and food, and years of geographic isolation has left the continent with no natural predator for this new invasive species. Currently, the rabbit inhabits around 2.5 million square miles of Australia with an estimated population of over 200 million. Feral Australian Rabbits as Ecological Problem Despite its size, much of Australia is arid and not fully fit for agriculture. What fertile soil the continent has is now threatened by the rabbit. Excessive grazing by the rabbit has diminished vegetative cover, allowing wind to erode away top soil. Soil erosion affects revegetation and water absorption. Land with limited top soil can also lead to agricultural run-off and increased salinity. The livestock industry in Australia has been widely affected by the rabbit. As food yields decrease, so does the cattle and sheep population. To compensate, many farmers extend their livestock range and diet, farming a wider expanse of the land and thus further contributing to the problem. The agricultural industry in Australia has lost billions of dollars from the direct and indirect effects of the rabbit infestation. The introduction of the rabbit has also strained the native wildlife of Australia. Rabbits have been blamed for the destruction of the eremophila plant and various species of trees. Because rabbits will feed on seedlings, many trees are never able to reproduce, leading to local extinction. Additionally, due to direct competition for food and habitat, the population of many native animals such as the greater bilby and the pig-footed bandicoot has declined dramatically. Feral Rabbit Control Measures For much of the 19th century, the most common methods of feral rabbit control have been trapping and shooting. But between 1901 and 1907, the Australian government went with a national approach by building three rabbit-proof fences to protect the pastoral lands of Western Australia. The first fence stretched 1,138 miles vertically down the entire western side of the continent, starting from a point near Cape Keravdren in the north and ending in Starvation Harbor in the south. It is considered to be the worlds longest continuous standing fence. The second fence was built roughly parallel to the first, 55 - 100 miles further west, branching off from the original to the southern coast, stretching 724 miles. The final fence extends 160 miles horizontally from the second to the western coast of the country. Despite the enormity of the project, the fence was deemed unsuccessful, since many rabbits traversed over to the protected side during the construction period. Additionally, many have dug their way through the fence, as well. The Australian government also experimented with biological methods to control the feral rabbit population. In 1950, mosquitoes and fleas carrying the myxoma virus were released into the wild. This virus, found in South America, only affects rabbits. The release was highly successful, as an estimated 90-99 percent of the rabbit population in Australia was wiped out. Unfortunately, because mosquitoes and fleas do not typically inhabit arid areas, many of the rabbits living in the continents interior were not affected. A small percentage of the population also developed a natural genetic immunity to the virus and they continued to reproduce. Today, only about 40 percent of rabbits are still susceptible to this disease. To combat the reduced effectiveness of myxoma, flies carrying a rabbit hemorrhagic disease (RHD), was released in Australia in 1995. Unlike myxoma, RHD is able to infiltrate the arid areas. The disease helped reduced rabbit populations by 90 percent in arid zones. However, like myxomatosis, RHD is still limited by geography. Since its host is a fly, this disease has very little impact on the cooler, higher rainfall regions of coastal Australia where flies are less prevalent. Moreover, rabbits are beginning to develop resistance to this disease, as well. Today, many farmers still use conventional means of eradicating rabbits from their land. Although the rabbit population is a fraction of what it was in the early 1920s, it continues to burden the countrys eco- and agricultural systems. They have lived on Australia for over 150-years and until a perfect virus can be found, theyll probably be there for several hundred more.

Whats a Good PSAT Score for 2015

What's a Good PSAT Score for 2015 SAT / ACT Prep Online Guides and Tips With all the scoring changes on the redesigned College Board exams, what counts as a "good score" on the PSAT these days? There are a few factorsyou can use to define what's good: score percentiles, National Merit criteria, andyour own personal goals for the PSAT and the SAT. First, it's critical to understand how the PSAT is scored. This guide will review the scoring scale of the PSAT, along with National Merit Scholarship Corporation's Selection Index, so you know what counts as a goodPSAT score. To start off, let’s go over a few key PSAT terms that will help you understand the rest of this guide. PSAT Scoring Terms: A Glossary Before examiningthe scoring scale of the PSAT, let’s review a few important terms: scaled scores, section (or test) scores, raw scores, subscores, and National Merit Selection Index. By understanding the difference between these terms and how they relate to one another, you’ll have a clearer understanding of the rest of this articleas wefigure out what makes for a â€Å"good† score on the PSAT. Scaled scores: your overall PSAT scores, which fall between 320 and 1520. Math accounts for half of this score (160-760), and the Reading section and Writing and Language section account for the other half together (160-760). Section (or test) scores: your scores by section, which fall between 8 and 38. You’ll get three section scores, one for Math, one for Reading, and one for Writing and Language. Raw scores: the number of correct answers by section. Your maximum potential raw scores varyby section. Subscores:seven scores between 1 and 15 that tell you how you did on certain types of questions. The questions fall into these seven categories:Command of Evidence, Words in Context, Expression of Ideas, Standard English Conventions, Heart of Algebra, Problem Solving and Data Analysis, and Passport to Advanced Math. National Merit Selection Index: the scale used by the National Merit Scholarship Corporation to determine eligibility for Commended Scholar and Semifinalist. The Selection Index for the PSAT will fall between 48and 228. As you can see,you’ll get a lot of different scoreson your PSAT score report. Now that you have a preliminary sense of these terms, let’s look in more detail at how the PSAT scoring system works. How Is the PSAT Scored? As you read above, the PSAT has aminimum possible score of 320 and a maximum of 1520. Both the low and high end of this range are shifted about 80 points lower than the scoring scale of the SAT, to account for the fact that the PSAT is a somewhat easier test. Math isscored from 160 to 760, and Reading and Writing (technically called Writing and Language) isscored together from 160 to 760. Math makes up half the total score while the Reading and Writing sections will make up the other half together. You can think of the PSAT as half math and half verbal. While your final score will lump Reading and Writing together, you'll get a chance to see your performance on each the three separatesections. In addition to your overall scaled scores, you’ll get three section scores - one for Math, one for Reading, and one for Writing, that fall between 8 and 38. These numbers may feel a little random, but it’s actually pretty easy to convert from your section score to your scaled score. To get your math scaled score, just multiply your section score by 20. To get your Reading and Writing scaled score, add your section scores together and then multiply by 10. This chart gives you one hypothetical example of a student who got section scores of 28, 32, and 34 on Reading, Writing and Language, and Math, respectively: Test Test Score Section Score Total Score Reading 28 (28 + 32) * 10 = 600 600 + 680 = 1280 Writing and Language 32 Math 34 34 * 20 = 680 At the risk of making things more confusing, I'll quickly add that your score report shouldalso tell you your â€Å"raw score,† which is simply one point for each correct answer. Since there are 47 questions on Reading, you could get a max raw score of 47. On Math there are 48 questions, so you could get a max raw score of 48. Finally, on Writing, there are 44 questions, so you could get a max raw score of - you guessed it - 44. Again, your raw score simply reflects the number of questions you answered correctly. Then that raw score is converted to a section score and, finally, your scaled scores. Now that you have a sense of the PSAT’s scoring system, let’s consider our original question: what isa good PSAT score? What Makes for a Good PSAT Score? There are a few ways we can define â€Å"good.† First, we can look at the scores that rank in a high percentile compared to the scores of other test-takers. Second, we can look at what scores qualify for National Merit distinction and scholarships. And third, we can look at what your PSAT scores predict for your performance on the SAT. Let's start by reviewing how percentiles work and how you can predictthe strength of your PSAT scores. Want to improve your SAT score by 160points or your ACT score by 4 points?We've written a guide for each test about the top 5 strategies you must be using to have a shot at improving your score. Download it for free now: What Are PSAT Percentiles? Once you get your scores back, you'll see the different values described above - your raw scores, your section scores, and your scaled scores. Additionally, your score report will tell you your percentiles. Your score report will tell you two percentiles: the Nationally Representative Sample percentile and the User Percentile. Your Nationally Representative Sample percentile may look higher, since it confusingly includes projections for all students in a grade, even those who typically don'tthe PSAT. It seems that your User percentile will be the most reliable piece of data, since it only includes students whoare actually very likely to takethe PSAT. Therefore, the chart below gives you User percentiles, or for how your PSAT scores compare to other students in your grade who took the test. So how do percentiles work? They simply tell you the percentage of students compared to which you scored higher or the same. If your scaled scores land in the 80th percentile, for example, then you scored the same as or higher than 80% of other test-takers. The other 20% scored higher than you. Students' performance varieson Math, Reading, and Writing, so a score of 600 on Math, for example, may translate to a different percentile than the same score on Reading and Writing. Readon to see how scores from the new PSAT are expected to convert to User Percentiles. What PSAT Scores Will Rank in a High Percentile? This chart has the full list converting PSAT/NMSQT scaled scores to percentiles.This information is sourced fromCollege Board's dataon the PSAT administered in October 2015. As you read through the chart, notice thatyou don't have to have a perfect scaled score to make it into the top 99%. This is important if you're aiming for National Merit - you don't have to get a perfect score to make it into the top 1%.

In previous years, the Math section was slightly more competitive than Reading and Writing. Similarly, math getsnoticeably more competitive as you look at the lowest scores, and you would need 30 to 40 points higher in Math than in Reading and Writing to score in the 99th percentile. For the most part, though, both sections look like the same scores convert to more or less the same percentiles.At a few levels, Reading and Writing looks to be even more competitive than Math.Let's take a closer look at these percentiles totry to answer our original question of what makes a good score on the PSAT. The higher percentage, the better. What's a Good PSAT Score Based on Percentiles? Based on the chart above, an average PSAT score, or one that's right in the middle in the 50th percentile, is about 490 for both Reading and Writing and for Math. We can define good as being not just above average, but also as stronger than a significantmajority of other test-takers. Given that definition, these are approximately the scaled scores you need in each section to score in the 70th, 80th, 90th, and 99th percentiles. Percentile Reading and Writing Score Math Score Composite Score 70% 540 540 1080 80% 580 570 1150 90% 620 620 1240 99% 700 740 1440 As you can see, both sections convert to roughly the same percentiles except when you approach the 99th percentile. Then you'd need to score about 40 points higher in Mathto make it into the top 1%. Apart from scoring higher than other students, you might define a good score as one that qualifies for National Merit. Let's take a look at what you need to qualify. Want to improve your SAT score by 160points or your ACT score by 4 points?We've written a guide for each test about the top 5 strategies you must be using to have a shot at improving your score. Download it for free now: The original National Merit Scholar. What's a Good PSAT Score for National Merit? The percentiles in the chart above compare students all across the U.S who typically take the PSAT. To determine whether you qualify for National Merit, though, you actually have to look at how your scores compare to those of other students in your state. The National Merit Scholarship Corporation (NMSC) compares scores on a state to state basis. It names the top 3 to 4% of students Commended Scholar. To be named a National Merit Semifinalist, you have to score at the very top. National Merit Semifinalist distinction is given to the top 1%. The important thing to remember about National Merit is that it uses its own Selection Index. Since the PSAT changed its scoring system this year, this new Selection Index differs from that used in previous years. Before scrolling down to the chart below, read this next section to make sure you understand thePSAT Selection Index of today. Important: NMSC'sNew Selection Index National Merit has always used its own Selection Index, or scoring scale, to determine Commended Scholars and Semifinalists. In past years, this Selection Index looked a lot like PSAT scaled scores, so you may not have noticed. This year, though, it looks quite a bit different, even though it’s calculated in a similar way. As you read above, the PSATlumps together the Reading and Writing sections in one final scaled score. National Merit, however, still wants to consider these two sections, Reading and Writing, separately. Therefore, NMSClooks at your section scores rather than at your scaled score. It takes your Math section score, Reading section score, and Writing section score - all of which fall between 8 and 38 - adds them together, and then multiplies by 2. The NMSC Selection Index hasa scale between 48 and228. Confused yet? Let's look at an example. The Breakdown: NMSC’s New Selection Index Where does NMSC get this scale of 48 to 228? Let’s say you got minimum scores of 8 on each of the three PSAT sections. You could figure out your Selection Index by adding 8 + 8 + 8 (= 24) and then multiplying by 2 (= 48). That’s the lowest end of the Selection Index scale. What about the max Selection Index score of 228? You could get that with top section scores of 38 in all three sections. 38 + 38 + 38 = 114. Multiply that by 2, and you get 228. Now you can see that the Selection Index isn’t as random as it might have looked at first glance - it just relies on your PSAT section scores between 8 and 38, rather than your PSAT scaled scores between 160 and 760.You can also see why we took the time to go over all these terms at the beginning of the article! Based on reported data from individuals around the country, we've put together a list of every Selection Index cutoff across the United States for the PSAT in 2015. If you see any error with your state, let us know in the comments! Here are the qualifying scores from the old PSAT (2014 and earlier) and the new PSAT (2015 and later). State OldPSAT Cutoff New PSAT Cutoff Alabama 207 215 Alaska 210 213 Arizona 213 219 Arkansas 206 213 California 222 221 Colorado 213 218 Connecticut 220 220 Delaware 215 218 District of Columbia 224 222 Florida 211 217 Georgia 215 219 Hawaii 214 217 Idaho 211 214 Illinois 215 219 Indiana 212 217 Iowa 207 215 Kansas 213 217 Kentucky 210 215 Louisiana 208 214 Maine 212 214 Maryland 221 221 Massachusetts 223 222 Michigan 210 216 Minnesota 215 219 Mississippi 207 212 Missouri 209 216 Montana 206 210 Nebraska 209 215 Nevada 208 214 New Hampshire 212 216 New Jersey 224 222 New Mexico 210 213 New York 218 219 North Carolina 212 218 North Dakota 201 209 Ohio 213 217 Oklahoma 206 213 Oregon 217 219 Pennsylvania 216 218 Rhode Island 212 217 South Carolina 209 215 South Dakota 203 209 Tennessee 212 218 Texas 218 220 Utah 208 215 Vermont 213 215 Virginia 219 221 Washington 219 220 West Virginia 201 209 Wisconsin 208 215 Wyoming 204 209 Average 212 216 As you can see,New Jersey, DC, andMassachusetts require some of the highest scores to qualify. The average qualifying scores for all states isa little lower at around 216. If you haven't taken the PSAT yet and areserious about achieving excellent scores, then I'd recommend aiming for at least 2 to 5 points higher than these cutoffs, as the actual qualifying scores can vary from year to year. How can you figure out your target section scores? By understanding where the new Selection Index comes from, you can take our estimate for your state and simply work backwards. Let’s consider a few examples. How to Calculate Your Target Scores for National Merit As you read above, National Merit will take each of your section scores between 8 and 38, add them together, and multiply by 2. To figure out your target scores by section, take these steps and go through them in reverse. First, divide your state’s cutoff qualifying score by 2. Let’s say you live in New Jersey, and your cutoff will be an estimated 222. Divide that in half and you get 111 (222 / 2 = 111). Now, your section scores in Math, Reading, and Writing should add up to 111. Divide 111 by 3 and you’re looking at a 37in each section: 111 / 3 = 37. You could define your target scores as about 37 in each section - or a little higher to be safe. If you’re more confident in Math, then you could aim for a top math section score of 38. Then you’d have slightlymore wiggle room in Reading and Writing. Depending on your strengths and weaknesses, you can setyour target scores in theoptimal way. To review, you can define your target section scores by dividing your state’s cutoff in half. Then divide by 3 to get a sense of what you need in each section of the PSAT. Customize your target section scores from there. Of course, only a small number of students are actually aiming to score in the top 1%. You may very well be deciding what's a good PSAT score based on your own goals for the test, as well as for the SAT and ultimately, college. Pause for your quintessential collegiate building. What's a Good PSAT Score for Your College Plans? Even if you're not competing for National Merit, the PSAT still matters and is an important test along the path to college. It's valuable practice for the SAT and can help predict your SAT scores. The redesigned exams are very similar, with matching content and format and comparable scoring systems. By doing some research into the colleges you're interested in, you can figure out what you need to score on the SAT. Simply Google the name of your school, along with "average SAT scores." Most schools release data on the average SAT scores of accepted students, so you have a sense of what you need to be a competitive candidate. Then you can use your PSAT scores to determine where you're currently scoring and how much more you need to improve. Based on your target scores and time you can commit to prep, you can design a schedule to prep and raise your scores. The following is a rough estimate of how many hours you need to devote to studying to achieve certain score improvements on the PSAT. 0-50 SAT composite point improvement: 10 hours 50-100 point improvement: 20 hours 100-200 point improvement: 40 hours 200-300 point improvement: 80 hours 300-500 point improvement: 150 hours+ Whether or notyou've already taken the SAT, your PSAT score is a useful starting pointto measure your level and figure out where you need to go from there. Then you can make a study schedule to get yourself where you want to be. Finally, these are the most important points to remember when you take the PSAT and determine whether or not you're satisfied with your scores. Key Points to Remember If youtookthe PSAT in October 2015, you were kind of a College Board guinea pig. 2015 wasthe first year featuring the redesigned PSAT with a new scoring scale and Selection Index.Remember that the PSAT is now scored between 320 and 1520, which is a composite of the Math section and the Reading and Writing sections together. To score in the 70th percentile or above, you want to aim for at least a 540in Reading and Writing and a 540 in Math (or a composite of 1080). To qualify for National Merit, you'll need something like an impressive Selection Index score of214, or a section score around 35 to 36 in Math, Reading, and Writing. The PSAT is a valuable benchmark that you can use to plan your studying for the SAT. Make sure to check your PSAT scores right away to see if you need to take any further steps, like for National Merit, and to move forward with your SAT prep. What's Next?

Culture Essay Example | Topics and Well Written Essays - 1000 words - 4

Culture - Essay Example Under this spectrum, the paper will establish similarities and/or differences by exploring cultural or religious traditions, symbols, or beliefs from my cultural background. Findings depict that culture traverses along broad measures and as such, it can be or appear as a myriad of many things that ranges from the food people eat to the ways in which people dress. It can even seek to explain how to obtain and prepare the said food. There are large numbers of factors that influence an individual’s culture. However, common thoughts suggest that when one brings the issue of culture into a debate, culture becomes something that is very narrow and defined (Havilland 44). As such, certain people define it as simply an area in which one resides in. Note that, structures of a family that comprise of things such as habits of a community, expectations and gender roles can have great impact on the ways in which one looks upon another’s culture. The ethnic background of an individual or a group provides a stepping-stone towards regarding a particular type of culture. When grows in a family, he or she takes up after the ethnic background of the respective family. This means that, society influences someone’s cultural response towards laws, morals, and rules of that society. Following practices and adhering to rules of the given society shapes one’s way of life, which in turn explains his or her culture (Samovar, Porter, and McDaniel 102). Bear in mind that, when one becomes deviant of these rules and laws of the society as depicted by the culture, he or she is liable for punishment. With reference to this aspect, it becomes paramount for one to accept and learn the cultural laws and rules of the society that he lives in, in order to avoid unnecessary punishments (Havilland 61). Since our cultural baggage composes of a wide range of cultural belongings, our daily

Human Society and Environmental Issues Essay Example | Topics and Well Written Essays - 500 words

Human Society and Environmental Issues - Essay Example Environmental issues come up because different societies tend to live for themselves and no longer consider the welfare of other issues. One example of this is the ocean. The ocean is a universal property wherein different sea creatures reside. No matter how hard Australia protects migratory whales during seasons that such creatures are in their waters, it becomes useless if these mammals are not protected in the same scale once they go to the waters of South East Asia during summer time. In this sense, environmental issues could be minimized if the nations where migratory whales visit will enter into an agreement to equally protect these species. The physical resources of the world are somewhat made available for everybody. Thus the care and protection of which must be done on universal level. The ozone layer, the ocean, these are all not bound by territory, thus demands cooperation in terms of its protection. However, there are environmental issues that strictly demand the action of local governments. It is a universally accepted rule that resources found to one country belong to that same country. And if such country will create laws that will support logging without any clause on inter generational duty, then the international society cannot do much about it. This also goes with multi national corporations that pollute the air, but continuously operates because of the protection given by their host country. All environment issues are political issues because politics govern the relationship between the government and its people.

It is essential to note that Coca-Cola serves various ages of individuals: Both the old and young person’s utilize the brand. Coca-Cola is widely spread around the world. The activities of Coca-Cola transcend bias even in low-income countries. The countries, under Coca-Cola service stretch from USA, Canada, Europe, Asia and Africa. The company’s headquarters manage a global channel of distribution. In turn, it produces diverse brands out of the traditional domain of soda brands (Hirschey, 2008).

In close relation to this, SWOT analysis addresses the loopholes to achieving an edge in beverage market. In addition, it addresses challenges and inevitable threats it faces from the markets and competitive field. The company possesses notable strengths. To begin with, Coca-Cola shares a long history of serving the beverage world. This is contrary to companies that feel out of the competitive field. Each emerging generation of customers are willing to identify with the brand. The brand name is a robust force that traverses across groups and countries. This help in the fact that individuals can easily relate to the brand without relating the same to a specific group’s link (Inkpen & Ramaswany, 2006). The company utilizes an effective advertising method of various t ypes to harness customer base. The company faces a weakness of offering almost similar products just as other beverage companies. Despite its strength, the brand loses out to other popular brands such as Pepsi.

How significant were the neandertals to the evolution of anatomically Essay

How significant were the neandertals to the evolution of anatomically modern humans - Essay Example Neandertal fossils date back to 130 000- 30 000 BP throughout the region of Eurasia. Their fossils were morphologically different from modern man in that they were ruggedly built with thick chest (Lahr 130). The Neandertals were very strong and muscular; an adaptation that helped them to survive in tough conditions. According to Hublin, the Neandertals spent most of their lives in caves given that their reign was during a period of long glacial maximum. Although referred to as ancient cavemen, recent archaeological studies have pointed out that the Neandertals were intelligent considering the fact they used stone tools and sometimes fire. (Ponced et al,13767). Thus, new evidence suggests that although the Neandertals were slightly physically different from the anatomically modern man, both shared a lot of characteristics. According to Roebroeks, anatomically modern man came into direct contact with the Neandertals about fifty thousand years ago (p. 438). The neandertals and modern ma n were forced to compete for the resources available like food and locations (Mellars 103). However, the highly specialized morphology of the Neandertals began working to their disadvantage due the climatic changes. There is no conclusive evidence to ascertain whether modern man was more evolve than the neandertals at this point in history. However, the discovery of cultural items associated with early modern man suggest that indeed, neandertals were less evolved in comparison (Hardy 35). Since both the neandertals and modern man shared diets, the competition for food grew fierce with time. Eventually, the neandertals were pushed towards harsh and less fertile environment which heralded their demise. It should be noted that modern man and neandertals were very similar. Research by Currat pointed out that modern man and neandertals had similar cultures (p. 15129). For instance, both were cognizant of the significance of death and tools of trade were inherited. Although they both had had significant morphological differences, their genetic distinction could still allow for mating to produce offspring that was viable. The possibility of interbreeding between modern man and neandertals may offer insight into the similar traits between the two (Weaver et al 464) . The gene of microcephalin is archeologically attributed to neandertal man. This trait was absent in modern man genome up to approximately one million years ago. Its presence in anatomically modern man thus points out to interbreeding with the neandertals. The gene that allowed for more brain development and intelligence was critical for the existence and survival of modern man (Ponced 1365). This gene was rapidly propagated through the modern man by positive selection and it is now present in a majority of the world population. Thus, it is evident that neandertals passed on some superior genes of brain development to modern man which contributed significantly to their evolution. The intelligence gene was advantageous to the progress and survival of anatomically modern man in a dynamic world. According to Blow et al, further research into the DNA of Neandertals has indicated compellingly that in deed anatomically modern man and neandertals interbred (1367). This conclusion was reached after the study found out that modern man had a gene that helped to develop resistance to virus that was previously found in

High and low culture Term Paper Example | Topics and Well Written Essays - 2000 words

High and low culture - Term Paper Example In order to understand the history and the relationship between the high and the low culture it would be necessary to refer to their basic characteristics. In accordance with Inglis, the term ‘low culture’ is used in order to describe ‘cultural products which exhibit qualities that are the opposite of great art’. However, at this point, the following problem appears: which would be the criteria on which the evaluation of a piece of art as of ‘high’ or ‘low’ culture would be based? It is explained that the views of people on art and quality can be differentiated. Works of art which are considered as of low quality for a particular individual may be regarded as exceptional by another person, i.e. subjectivity when referring to high or low culture cannot be avoided. At the same time, low culture has been related to the characteristics/ background of the creator, meaning that culture produced by people belonging in disadvantage minorities is likely to be considered as ‘low’ even if its quality is significant. On the other hand, it is made clear that the distance between high c ulture and everyday life is not so high as believed. It is noted that high culture can be used, at the same level as the low culture, for understanding the cultural trends of people within a particular society. On the other hand, Ferrarotti notes that the differentiation between the high and the low culture – also known as popular culture – reflects ‘the dichotomy between articulated culture and culture conceived of as a mode of life.

Homework - Article Example ool, and the selected classes are handled by the same teacher and the exercises given to them were also the same, to attain uniformity in the analysis. The study has a rationale relating to the efficacy of homework in cases were family involvement is ensured. This had been studied previously by many researchers, but this particular study interrogates three situations where 1. the students are not prompted to involve their family in homework, 2. the students are prompted to involve their family in homework and 3. the students and teachers are prompted to involve the parents in homework. The research has further significance in the theoretical and application level, as it tackles different issues related to the performance of students with reference to the involvement of their families in their homework. The literature is reviewed extensively, linking the research to Project Head Start, which involves studies related to involving parents in homework. Moreover, sufficient insights are drawn from pioneer researchers like Epstein and Bronfenbrenner. Moreover, the study cortically evaluates previous research and points out the areas where more studies have to emerge. The study justifies the need for studying the problem and elaborates its scope in related fields. The previous studies are incorporated in the analysis, but the study remains original. There are four clearly defined research questions relating to the significance of prompts in the involvement of family members in mathematics homework, the way this affects homework in other subjects, the relationship between family involvement and student achievement and the relationship of all these with regard to the selected family variables including parent education level, family structure and family size. The hypotheses are consistent with theory and known facts, as evidenced by the way they are linked to previous research and established facts. They are testable, and suitable testing methods are applied. They bring

I hold my duty as i hold my soul both to my God Essay Example for Free

I hold my duty as i hold my soul both to my God Essay Polonius statement, found in Act Two, Scene Two, reflects the symmetry and order of the society he lives in. He inhabits a world of certainty and medieval convention. The play can be seen to challenge the statement, both in the action and in the characters, particularly in the character of Hamlet himself. It is Hamlet, the renaissance man of the play, whose controversial attitude is constantly seen to challenge the medieval certainties that could still be seen in Jacobean society. Value was placed on duty to the monarch and to God; the institution of marriage was sacred and scientific reasoning was absolute and definite. All these things are challenged in Shakespeares Hamlet. The social and cultural climate of Jacobean society was such that certainties and conventions were held in high esteem- Shakespeares Hamlet is written in the context of, for example, the social hierarchy of the time, the medieval court, and religion. All of these are challenged in the play by both the characters and the plot. Even the very form of the statement challenges these certainties, for the couplet is a chiasmus- the symmetrical structure reflects the very nature of the society in which Polonius lives. In Shakespeares time society was beginning to ask some of the questions which Shakespeare addresses through the character of Hamlet. Most people embraced a rational, scientific line of thinking Elizabethans were not always heavily superstitious. For example, in Act one, Scene one, Horatio expresses doubt at the existence of the ghost: Before my God, I might not this believe Without the sensible and true avouch Of mine own eyes. They also began to question the old hierarchy and the natural order of things- such as God and gracious king upon the dawn of the Renaissance. The idea of society as a fixed structure and everything being ordained in the world was indeed a strong certainty. Hamlet has a clear vision of things as they are he is a realist, a Renaissance man, unlike characters such as Claudius and Polonius who Shakespeare portrays to be lacking in vision. Shakespeare shows the court to be full of people who think that all these things are absolute simply because they have always been a certain way. Hamlet is also the main vehicle through which Shakespeare conveys his views. Hamlet has indeed been brought up with medieval and religious certainties too. Or that the everlasting had not fixd His canon gainst self- slaughter. A modern audience may very well see Hamlet as being rather tame- a twenty-first century rebel would not acknowledge proprieties such as the divine ban on suicide- but Hamlet seeks more than revenge. He is a melancholy individual, who searches for the answers to some of these questions; through the title statement, Shakespeare challenges his contemporary audience and the modern audience to question these certainties too. Hamlets clear vision is in direct contrast to the other characters, in the sense that he is the only character who is prepared to question these certainties and to try and define, in a sense, what the true meaning of life is, what it is all about. Shakespeare challenges the statement of duty to God and king by implying, through the character of Hamlet that life is underpinned by something other than the monarch and the church. Hamlet is totally aware of the beauty of the world yet at the same time has a pessimistic outlook on the gifts of man as we are all destined to die anyway: What piece of work is a man, How noble in reason, how infinite in faculties, in form and moving how express and admirable, in action how like an angel, in apprehension how like a god: and yet to me what is this quintessence of dust? The character of Polonius is underpinned by values such as duty to God and king- this is illustrated not only in Act Two Scene Two but also in Act One Scene Three: This above all : to thine own self be true, As it must follow the night the day Thou canst not then be false to any man. This quotation illustrates a simplistic outlook on life. The main way in which Shakespeare challenges this outlook is, ironically, in Polonius death. In Act Three, scene four, Polonius is casually and ignominiously killed by Hamlet : O, I am slain. Polonius expresses surprise as much as anything, while Hamlet s words reinforce the irony of Polonius self- importance: I took thee for thy better. Take thy fortune: Thou findst to be too busy in some danger. Polonius is clearly at home in this ordered society and shows a passive acceptance of the status quo. He has a simple medieval outlook on life and clearly values his duty to his God and king; however, he dies by ridiculous accident. Although throughout his life he has clearly endeavoured to serve these two entities to the best of his ability, he still dies an unnatural, brutal death. Shakespeare is therefore illustrating the irrelevance that these values have to life, both in Shakespeares era and now. The statement which Polonius makes in Act Two Scene Two about duty to God and King allows the reader to infer a lot about the character of Polonius and the world in which he lives- he does not seek new experience. These medieval certainties are also challenged in the character of Claudius. He is obviously not on the side of God- indeed, he seems to contradict the very reasoning of the church by the brutal manner in which he murders the king. It is ironic therefore that he seems to declare himself king by divine right as he actually dies with a guilty conscience: Theres such divinity doth hedge a king That treason can but peep to what it would, Acts little of his will. Here it appears that Claudius has conveniently forgotten exactly how he became king. Shakespeare is challenging the idea of kingship. He is showing the court to be full of people who think things are the way they are because they have always been done that way, such as Polonius, Gertrude, Claudius, and Rosencrantz and Guildenstern. The character of Claudius highlights the corruption of the medieval court. The intrigue and machiavellian machinations of the court are self justifying to all these people; for example, Rosencrantz and Guildenstern deceive Hamlet and go behind his back simply because they are serving their king. In Shakespeares time deception and violence were commonplace if they would benefit the king. Although Claudius seems to take the moral high-ground throughout the play he has no good intentions toward Hamlet at all. Shakespeares Hamlet also challenges the institution of marriage- it is shown in the conduct of Gertrude and Claudius not be a sacred union but a justification for excessive promiscuity. Hamlet is distraught by his mothers rapid re- marriage to his uncle after his fathers death: To post with such dexterity to incestuous sheets. Shakespeare invites us then to question the notion of a stable royal marriage, and the values that society had then and the values we have now. Hamlet is disgusted by their sexual excesses and, moreover feels he has been tainted by them: O that this too too sullied flesh would melt, Thaw and resolve itself into a dew. Shakespeare is challenging the morality of the royal marriage- the fact that Gertrude marries the kings own brother shortly after his death seems to suggest the absence of love. In Hamlet, the degree of emotion and true respect in marriage is shown to be weak- it is easily overruled by lust, as the ghost of the previous king states: Let not the royal bed of Denmark be. A couch for luxury and damned incest. Hamlet is an unconventional revenge tragedy- Shakespeare subverts the genre. Hamlet is reluctant to take revenge whereas Laertes is hot- headed, impulsive and ready to avenge the murder of Polonius: It warms the very sickness in my heart That I shall live and tell him to his teeth, Thus diest thou. Shakespeare undermines the concept further by showing that Hamlet is not in fact a coward- his ideas are slightly more subtle. He is indeed hesitant about avenging his fathers murder- he passes up an opportunity to kill Claudius in Act Three, scene four, as he does not want to kill him in an act of redemption. This goes against the traditional idea of medieval and Jacobean revenge: A villain kills my father, and for that To heaven. Why, this is hire and salary, not revenge. This is a challenge to the genre because Hamlet is prepared to bide his time in order to achieve the perfect murder- he wont be spontaneous and impulsive. This is shown by the fact that he passes up an opportunity to kill Claudius. Shakespeares Hamlet has a good degree of relevance to life in the twenty- first century. Although some of the major themes, such as the court and incest, are no longer applicable to modern life, we can relate to some of the underlying themes such as love, sorrow and resentment; we can relate to the emotional distress. Reasoning in Medieval Denmark where the play is set nor indeed in Jacobean society is not so different to our reasoning today- the majority of people today may not believe in ghosts but characters in the play, such as Horatio, and some people in Jacobean society do not believe in ghosts either. In Act one, scene five, Hamlet makes this very thought- provoking comment to Horatio: There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy. We have our certainties today- in the form of scientific reasoning; but our certainties are equally open and capable of being challenged. One of the main themes in Hamlet is death- we are still uncertain about what happens after we die. The character of Hamlet himself has a romantic, post modernist way of thinking; everything is relative and there are no certainties- only thoughts: Nothing is good or bad. Thinking makes it so. In a sense here Hamlet can be compared to the Romantics. Keats wrote in the context of Shakespeare: Twixt damnation and impassiond clay. (On Sitting Down To Read King Lear) This in a sense is what underpins Shakespeares Hamlet- the idea that whatever certainties are held in any given era will always be questionable, and open to discussion. Our certainties will always be challenged because nothing is definite, or absolute. This romantic concept is based on the idea that this is what life is about- challenging certainties in order to try and discover the ineffable truth about this world and the next.

John Strachan, First Bishop of Toronto - The Holy Terror :: Canadian Canada History

John Strachan: The Holy Terror Many individuals appear to have honourable intentions but often their objectives are flawed. John Strachan lived through and influenced many key events of Canadian history. He was a highly esteemed teacher of wealthy Loyalist children, a pastoral leader during the War of 1812, a supporter of education, a member of the government, he played a prime role in the Rebellions of 1837 and he eventually rose to become the first Bishop of Toronto. John Strachan had a highly Loyalist view towards the governing of Upper Canada; he was especially faithful to the betterment of the Church of England. Strachan was in favour of a purely British Upper Canada or at least one run according to British standards. Although Strachan believed that the best way was the British way, many individuals in Upper Canada disagreed. Strachan's attempts to monopolize all opportunities in favour of the British caused public uproar and debate. His controversial role in government was regarded by some as unnecessary and ungodly since he was a supposed man of God. His manipulation of events were protested but usually accepted; his skills of influencing were uncontested. John Strachan used his powerful status to negatively influence Upper Canadian society. John Strachan's harmful intentions are evident in his supporting of the monopolization of the clergy reserves, controlling of non-British immigration, lobbying strictly for Anglican education in schools, his manipulation of the government and his poor reputation amongst the public. John Strachan believed that the Anglican control of the clergy reserves was necessary in order to ensure a truly British Upper Canadian society. For example, the Constitution Act 1791 stated that one-seventh of land in Upper Canada was to be reserved for the "Protestant Clergy". In a letter to the Bishop of Quebec, Jacob Mountain, Strachan stated, "The words 'Protestant Clergy'...refer exclusively to the Clergy of the Church of England" (Henderson b 86). Strachan refused to acknowledge other Christian denominations because he wanted to ensure the future of the Anglican Church and Anglican educational ideals. When the bishop came to visit in 1820, he established John Strachan as the chairman of the Clergy Corporation; he was made responsible to collect and manage all revenue made from the clergy reserves. For four years, Strachan was in charge of a vast amount of wealth until the Presbyterians launched protests declaring that they had a right to the land.

A Marxist Reading of Shakespeares Coriolanus Essay -- Coriolanus Essa

A Marxist Reading of Coriolanus      Ã‚  Ã‚   One popular dissecting instrument of any Shakespearean character is the modern tool of psychoanalysis. Many of Shakespeare's great tragic heroes-Macbeth, Hamlet, King Lear, and Othello, to name a few-have all been understood by this method of plying back and interpreting the layers of motivation and desire that constitute every individual. Add to this list Shakespeare's Roman warrior Coriolanus. His strong maternal ties coupled with his aggressive and intractable nature have been ideal fodder for modern psychoanalytic interpretation. This interpretation, however, falls within a larger, political context. For despite the fact that Coriolanus is a tragedy largely because of the foibles of its title character, its first and most lasting impression is that it is a political play. Indeed, the opening scene presents the audience with a rebellious throng of plebeians hungry for grain that is being hoarded by the patricians. When Menenius, a patrician mouthpiece, enters the scen e a dialectic is immediately established, and the members of the audience inexorably find themselves on one side or the other of this dialectic, depending, most likely, on their particular station in life.    The English nobility that viewed this play in Shakespeare's time undoubtedly found Menenius' fable of the belly compelling, in which the belly-representing the patricians-is said to be a distribution centre that may initially receive all the flour (nourishment), but parcels it out evenly to the various limbs, and organs-representing all other classes of the republic-leaving itself only the bran. I doubt the audience in the pit found this body trope very persuasive, especially since this play was initially per... ...bject of our misery, is as an / inventory to particularize their abundance; our / sufferance is a gain to them" (I.i.16-18). By rioting for grain and then banishing Coriolanus, the citizens are taking what limited steps are available to people of their class to effect change and receive recognition of their voices. Their insurrection will indeed throw forth greater themes, one of which will be emancipation.    Works Cited Appignanesi, Richard. (1976). Marx for Beginners.

Sydney Kpundeh Professor Couch Introduction to Philosophy 1101 February 23, 2013 Artificial Intelligence The year is 2013 and technology dominates our day and age. Our society is turning to one that requires some sort of technology to survive. One may argue that a lot of people have cell phones or know how to use one. That can range from a ten year old child, to an eighty-five year old grandmother. One may also argue that most households have either a television or computer or even both in most cases.The use of technology in people’s lives is growing and therefore the demand for technological products. Children are addicted to playing games on their PlayStation or texting their buddies and their parents are busy sending emails and checking stocks on their iPads’. With this steady growth in usage of technology in people’s lives, the demand for these machines is also growing. Competitors selling these machines compete to make their products better than the rest of the sellers, constantly keeping them updated and in tune with what people would want to see in these machines and what they need from them.For example, let us look at â€Å"SIRI,† which is software developed by the company Apple. It is an intelligent personal assistant which is used in Apple products. Siri is given a woman’s voice and uses it to answer questions, make recommendations, and perform actions by delegating requests to a set of Web services. Most machines in this generation are equipped with this personal assistant ability or something very similar. This new recent development in machines has stirred a very interesting debate amongst philosophers.That debate is whether or not machines have the ability to think. Alan Turning, who was a computer scientist, wrote a 950 page paper in the 1950s, about a way to test whether machines can actually think. It became known as the Turning Test for Thinking Machines. In his paper Turning also outlines some objections peo ple had to machine intelligence. Christopher Evans was also a computer scientist and he also wrote a paper entitled, â€Å"Can Machines think† in which he summarizes Turnings objections, comments on them, and also gives his own opinion on the subject. In this paper, I will ocus on two of his objections to the thesis that machines can think that Evans considers and replies to, and I will explain my side on those issues. The first objection is the Theological objection—â€Å"Man is a creation of God, and has been given a soul and the power of conscious thought. Machines are not spiritual beings, have no soul and thus must be incapable of thought† (Evans 221). This argument objects to the thesis that machines can think. Evans leans on what Turning already pointed out in his paper, that this objection puts an unwarranted restriction on God. Why shouldn’t he give machines souls and allow them to think if he wanted to? † (Evans 221). Evan replies by sayin g that this is irrefutable. If we define thinking as something that only man can do and something that only God has the power to grant, then machines cannot think because God created man with the ability to think. Man created machines but since man does not have the same powers as God, they are not able to give these machines the ability to think. Therefore machines cannot think. I am a strong believer in God and I believe he created all living creatures on this earth, along with humans and the ground we inhabit.Everything else that we see now in the world is a byproduct of those 3 things and therefore not a creation by God. That means that they do not have the same functions as the things created by God. Thought is one of those functions. A building was created by man and nobody would argue that a building has the ability to even speak yet alone think. Machines, like computers, iPods, iPhones, PlayStations, etc. , were all created by Man. Therefore just like a building, there shoul d not even be a debate about whether or not they have the ability to think.Just like how building designs have become more sophisticated, machines have also had significant advances from when they were first created. However all of these new developments are additions by humans and they have nothing to do with the primary functions of the building or machine. Buildings are still made to keep things in and keep things out. Machines are made for entertainment and to help our lives as humans run smoother. Nothing has changed. I agree strongly with Evans on this point which rejects the idea that machines can think, and believe he makes a good argument.The second objection is the Unpredictability objection- â€Å"Computers are created by humans according to a set of rules and operate according to carefully scripted programs which themselves are sets of rules. So if you wanted to, you could work out exactly what a computer was going to do at any particular time† (Evans 223). That b eing said, computers therefore are totally predictable. Humans however, are unpredictable and do not operate according to a set of rules. Therefore because humans are unpredictable, they are capable of error, which cannot be said about the predictable machines.The fact that machines are incapable of error and every one of their moves are predictable means that they do not have the ability to think. Evans replies by rejecting this thought. He says that machines nowadays are more complex and dynamic that they can surprise us and make mistakes. Although they are programmed in most of their actions, some still have the ability to re-program themselves and therefore can be unpredictable. Consequently, Evans argues that in this aspect machines have the ability to think. I disagree with Evans on this reply because I do not think he makes a strong argument.I will use the Siri example mentioned earlier to help support my position. Siri was programmed by Apple and all of Siri’s functio ns and response have been thought out and tested, and therefore predictable. However, it is impossible to predict everything that Siri says. Siri can surprise people because its response, even though they are predicted, caters to the user’s personality, interest, and likes. Siri saves and takes a note of every action you perform on your phone, or Apple product. If you constantly search for close McDonalds in the area and then ask Siri for example, what do I feel like eating today? It is highly probable that Siri is going to respond McDonalds. That does not mean Siri is thinking. It just means that is was programmed to study your search habits and interests. Siri could also say Wendy’s, because it knows you like fast food and Wendy’s has the same type of food as McDonalds, but it knows you always eat McDonald’s and could use something different to eat. That again does not mean that Siri is thinking, it just means it is programmed to sort through your likes and habits, and decided to suggest something which was not what ost people would have predicted. This is just another reason why I believe machines cannot think. This debate is a very intriguing one. Previous generations probably would turn in their graves if they actually knew that we were spending time and money debating and researching the thought of machines having the ability to think. However now the time being the 21st century and with all the technology advances that comes with living in this age, it is a very plausible debate.The thesis and the common belief now is that these new machines, from phones to cars, think on their own but like Evans, I disagree with this argument. Although there can be valid cases for machines thinking on their own, and Evans even agrees with the norm on some occasions, there still is not enough evidence today to turn that claim into a fact. Evans makes very strong cases for why they still cannot think, cases that I have commented on above and s tated my view, but in the end it goes down to the fundamental definition of the word â€Å"think†.Webster’s dictionary defines the word think as –â€Å"have a particular opinion, belief, or idea about someone or something: â€Å"she thought that nothing would be the same again. † Based on that definition alone machines cannot have their own opinions or beliefs about something. A car cannot, for example, not feel like driving today so it refuses to start. Therefore machines cannot think and they will never gain the ability to think because you cannot give someone or something an opinion.

Silicones And Solar Power Engineering Essay

AbstractionThis study aims to discourse the subject of solar power and silicones. In that it aims to discourse the development of solar energy extraction engineering over the clip period of fifteenth Century BC to show twenty-four hours. Besides included in this study are brief treatments of the types of solar aggregators presently in usage and the developing engineerings in this field. It further addresses the subject of silicones. First it will dissect the formation of silicones. The assorted procedures involved in the industry, and polish of Silicones.

The Final purpose of this study is to discourse the possible usage of silicones in PV faculties, in peculiar their usage as a coating for solar panels. Besides it aims to reason that the usage of silicones will lengthen the life of solar faculties by giving equal protection to the solar cells. The study is based on research carried out relevant to the subjects above mentioned. Research was carried out utilizing assorted web sites, a TCE article and books, subsequently referenced in the study. The consequence of this study is the research carried out on the subject. The chief decision of this study is the recommendation for the hereafter usage of silicones in the production of PV faculties.IntroductionThe topic of this study is to analyze the subject of solar power and potency for silicones in the country. The chief job being handled in this study is whether the usage of silicones is a executable method for bettering the life anticipation of solar faculties. Solar energy is a topic really much in current treatment as renewable energy Begins to be viewed with more favors, due to the frights of a possible deficit of fossil fuels, and an increased fright of the inauspicious effects of the combustion of these fuels. The intent of this papers is to foreground the possibility of solar energy as being a feasible beginning of energy in the hereafter and to foreground the betterments that can be made to solar cells, and thereby solar faculties by utilizing silicones as portion of their industry. The range of this papers extends to a brief treatment of the development of solar energy engineering over the clip period of fifteenth Century BC to show twenty-four hours. It besides briefly trades with the subject of the formation of silicones and their current usage. The research for this subject was carried out over a period of 10 hebdomads.Theory: Solar EnergyHistoryThere is a popular belief that solar power has merely been around for the past four or five decennaries. But in world it has been around for much longer. Let us get down with the earliest reference of the usage of the Sun for the benefits of adult male, in the fifteenth Century BC. Though it may be nil more than a myth, there is reference of the â€Å" Sounding Statues † of the Egyptian Pharaoh Amenkotep III. He claimed that his statues operated when the air in their base bases expanded after exposure to sunshine. Another possible myth sing the usage of solar power is 212 BC. In one of the most dramatic of early applications of solar energy it is said that the Grecian mastermind Archimedes. Harmonizing to legend he used a â€Å" Burning mirror † mirror to put the ships of the occupying Roman ships alight. He did this while they were still about 121.4 ft off. From Archimedes we move into the seventeenth Century AD The first application of solar energy after the autumn of the Roman Empire was in 1615. Salomon de Caux constructed the first device to be categorized as a â€Å" solar engine † . He constructed a device made of glass lenses, a supporting frame and an air-tight metal vas incorporating H2O and air. Its map was merely to bring forth a little H2O fountain when the air heated up during operation. It was considered more a plaything than a workhorse device. The physicist Athanasius Kircher ( 1601-1608 ) experimented during the mid 17th century with mirrors. He attempted to put fire to wood at a distance in an attempt to animate the so 1,800 twelvemonth old technique of Archimedes. Where Kircher worked with mirrors, a German mathematician, Ehrenfried Von Tschirnhaus ( 1651-1708 ) focused his work on lens type concentrators. He designed and constructed lenses up to about 30 inches in diameter. Using these he was capable of runing ceramic stuffs with concentrated sunshine. With this we take leave of the 17th century and switch our focal point to the eighteenth century. One of the most active figures in the eighteenth century with respects to solar energy was a Gallic scientist, George Louis Lecrec Buffon ( 1707-1788 ) . He was responsible for a series of multiple-mirror solar furnaces, the largest consisting of some 360 little planar mirrors, all separately focussed on a common point. In 1747, in the Gallic Royal Gardens, Buffon used 168 mirrors to light a heap of wood from a distance of about 195 ft. Buffon concluded that Archimedes could in fact have set fire to the Roman ships, but he estimated that he could non hold done so from a distance greater than 150ft. He based this decision about strictly on the premise that Archimedes was utilizing engineering far inferior to his ain, and hence could non hold equalled his ain device. Regardless of Buffon ‘s â€Å" decision † the inquiry sing Archimedes ‘ â€Å" Burning Mirror † still remains open. In 1977 D. L. Simms wrote in â€Å" Burning Question † Scientific Am. 236 ( 6 ) :64 ( 1977 ) 2, that â€Å" there are ample historical, scientific, and military evidences for reasoning that Archimedes did non utilize a combustion mirror as a arm of war â€Å" . Simms felt that Archimedes would hold been capable of ciphering the radiant flux necessary to make the occupation, and that Archimedes would non hold used a method of such low chance of success. Claude Poillet, a Gallic mathematician-scientist was one of the first people to concern himself with mensurating sunlight strength. He estimated that â€Å" the useable energy from the Sun per square pace of the Earth ‘s surface between the equator and about 43A ° N or S latitude was about 1/6 thermic unit per second, which corresponds to about one HP † 3. A Swiss naturalist, Nicholas de Saussure ( 1740-1799 ) , conducted the first recorded experiments in utilizing solar beams for cookery intents. His solar oven was called a â€Å" heat box † . Its composing consisted of multiple detached glass screens positioned over a blackened surface. The underside and sides of it were surrounded with insularity. It was recorded to hold achieved a temperature of 320A °F. The nineteenth century brought away a somewhat different solar oven. It was introduced by an English uranologist, John Fredrick Herschel. He built as little solar oven while on a trip to Africa ‘s Cape of Good Hope. It was constructed of mahogany painted black. He so buried it in the sand for intents of insularity. The lone portion of it left exposed was a dual glazed screen. This served to minimise heat loss from the top, while still allowing in sunshine. The oven is reported to hold reached a maximal temperature of 240A °F 1. In 1839 A. Edmund Becquerel, a Gallic physicist foremost discovered the photovoltaic consequence while experimenting with metal home bases. He discovered that some stuffs were photoconductive and could make little electrical charges when exposed to light4. However the first photovoltaic cell was non built until 1882, by an American discoverer Charles Fritts. He coated the semiconducting material Se with an highly thin bed of gold to organize the junctions5. One of the most fecund â€Å" solar energy innovators † was a Gallic Physics professor Augustin Mouchot ( 1825-1911 ) . Mouchot was responsible for originating 20 old ages of authorities funded experimentation with reflector type concentrators in 1860. His attempts in the field led to the construct, design and building of the first reflector devices based on the form of a abbreviated cone. These devices are now known as axicons. They were intended to concentrate sunlight along the cardinal axis of the cone instead than its predecessor devices which were designed to concentrate visible radiation to a individual point focal point. Mouchot built several solar powered steam engines between 1864 and 1882. Mouchot ‘s reflectors were built of â€Å" silver plated sheet metals, appropriately mounted so that the full device could be easy turned to follow the place of the Sun. The collection surfaces ( of a typical Mouchot assembly ) had an country of 40ft2 and was connected to a boiler which received about 87 % of the Sun ‘s heat † 3.Due to the available engineering of the clip the devices were connected to extremely inefficient steam engines, which yielded overall low public presentation. Though the eighteenth century brought the greatest organic structure of work on the solar energy forepart and the nineteenth century saw the superb Mouchot and his innovation of the abbreviated cone shaped reflector. It was the twentieth century that brought solar energy engineering to new degrees of variegation. In 1900 and 1911, patents were issued for sub-atmospheric-pressure solar engines, to E. H. McHenry. These engines used working fluids to bring forth power. Water was used to roll up heat and â€Å" a on the job fluid of lower boiling point than H2O ( was used ) to drive † 1.E. C. Ketcham received a patent for a similar system in 1905. The two- fluid system was introduced to avoid the low efficiency jobs which had been observed by Mouchot. The first experiments with level home base aggregators began in 1902. They were carried out by H. E. Willsie and John Boyle, Jr. The level home base device was a really shallow box with a black internal surface, a clear glass screen home base. The device was cooled by some signifier of transportation fluid flow normally H2O. This type of device does non concentrate sunshine as do lens-type and mirror type aggregators. However it is able to roll up and use diffuse sunshine every bit good as direct radiation, therefore their device was able to run over more widely changing conditions conditions. It was reported that though their device was built utilizing petroleum stuffs, its public presentation was such that â€Å" even in cold natural October conditions ( temperatures ) were high plenty to zap sulfur dioxide for the engine. â€Å" 1 In 1907 research began on level home base aggregators by Frank Schuman, of Philadelphia. Again, like Willsie and Boyle, H2O was used as the heat transportation fluid and a 2nd fluid was used to drive a steam engine. The fluid used was ether. His installing was located in Tacony, Pennsylvania, and included 1200ft2 of aggregation surface. The engine developed 3.5 horsepower, with a boiler temperature of 240A ° F. Encouraged by the public presentation of his units Shuman founded the Eastern Sun Power Company Limited in 1908.Types of Solar Collectors Presently in UseFlat Plate Collectorhypertext transfer protocol: //www.solarserver.com/uploads/pics/flachkollektor-e.gif A level home base aggregator consists of an absorber, a transparent screen, a frame, and insularity. 6 Traditionally an iron-poor solar safety glass is used as a transparent screen. This is because it transmits a great sum of the short-wave visible radiation spectrum. Simultaneously, merely really small of the heat emitted by the absorber escapes the screen due to the nursery consequence. Besides the transparent screen prevents wind and breezes from transporting the collected heat off, by convection. Together with the frame, the screen protects the absorber from inauspicious conditions conditions.6 Typical frame stuffs include aluminum and galvanized steel, and on occasion frames are made of fibreglass-reinforced plastic. The intent of the insularity at the dorsum of the absorber and on the side walls is to decrease the heat loss through conductivity. Usually insularity is polyurethane froth or mineral wool, sometimes mineral fiber insulating stuffs like glass wool, stone wool, and fiberglass is used. Heat loss can be reduced within the frame by convection air can be pumped out of the aggregator tubing. Such aggregators can so be called evacuated- tubing aggregators. These must be re-evacuated one time every one to three years.6 This brings us to the subject of evacuated tubing aggregators.Evacuated Tube Collectorshypertext transfer protocol: //www.solarserver.com/typo3temp/pics/5fb2adc895.gif In this type of vacuity aggregator, the absorber strip is located in an evacuated and force per unit area cogent evidence glass tubing. The heat transportation fluid flow through the absorber straight in a U-tube or in counter-current in a tubing in tubing system. The solar aggregator is composed of several serially interconnected, or tubes connected to each other via manifold. 6 A heat pipe aggregator incorporates a particular fluid which begins to zap even at low temperatures. The steam rises in the single heat pipes and warms up the carries fluid in the chief pipe by agencies of a heat money changer. The condensed liquid so flux back into the base of the heat pipe. The pipes must be angled at a specific angle above the horizontal to guarantee that optimum degrees of the procedure of evaporating and distilling maps. There are two types of aggregator connexion to the solar circulation system. Either the heat money changer extends straight into the manifold, and called a â€Å" wet connexion † , or it is connected to the manifold by a heat- conducting stuff, and called a â€Å" dry connexion † . A â€Å" dry connexion † allows the exchange of single tubings without necessitating the voidance of the full system of its fluid. Evacuated tubings offer the advantage that they work expeditiously. An advantage offered by evacuated tubings is that they work expeditiously with high absorber temperatures and with low radiation. Higher temperatures besides may be obtained for applications such as hot H2O warming, steam production, and air conditioning.6Solar panelhypertext transfer protocol: //upload.wikimedia.org/wikipedia/commons/thumb/e/ee/Photovoltaic_panel_at_the_National_Solar_Energy_Center_in_Israel.jpg/220px-Photovoltaic_panel_at_the_National_Solar_Energy_Center_in_Israel.jpg ( PV cellsA connected together in a solar panel. ) A solar panel is a aggregation of interrelated solar cells which are besides known as photovoltaic cells. Solar panels can besides be used as constituents of larger photovoltaic systems used to bring forth and provide electrical power for commercial and domestic applications. Due to the fact that a individual solar cell can merely bring forth a limited sum of power, many installings contain a several panels. A typical photovoltaic system contains an array of solar panels, an inverter, complecting wires and a battery. 11Photovoltaic CellsPhotovoltaicsA ( PV ) is a method of bring forthing electrical power by convertingA solar radiation intoA direct current electricityA utilizing semiconductorsA that exhibit the photovoltaic consequence. 12 On exposure to light electromotive force or a corresponding electric current is created in a stuff. The photovoltaic consequence is straight related to the photoelectric consequence. But the two procedures are different and should ever be distinguished. In the photoelectric consequence, negatrons are ejected from a stuff ‘s surface upon exposure to radiation of a sufficient energy. In the photovoltaic consequence nevertheless there is a difference. The negatrons generated are transferred between different sets within the stuff ( i.e. from the cornice to conduction sets ) , ensuing in the physique up of a electromotive force between two electrodes. In most photovoltaic applications the radiation, is sunlight and due to this ground the devices are known as solar cells. In the instance of a p-n junction solar cell, upon light the stuff creates an electric current as aroused negatrons and the staying holes are swept in different waies by constitutional electric field of the depletion part. Photovoltaic power coevals employsA solar panelsA composed of a figure of cells incorporating a photovoltaic stuff. Materials soon used for photovoltaics include monocrystaline Si, polycrystalline Si, formless Si, Cd telluride, and Cu In selenide/sulphide. P V Cell diagram Solar panels use light energy, i.e. photons, from the Sun to bring forth electricity utilizing the photovoltaic consequence. The burden transporting member of a faculty can either be the top bed or the back bed. 11 The modern photovoltaic cell was developed in 1954 atA Bell Laboratories.A This extremely efficient solar cell was foremost developed byA Daryl Chapin, A Calvin Souther FullerA and Gerald Pearson in 1954 utilizing a diffused Si p-n junction. The interrelated solar cells are normally embedded in crystalline ethene vinyl ethanoate, fitted with an aluminium or chromium steel steel frame and covered with crystalline glass on the front side to do a solar faculty. The bulk of solar faculties use wafer-based crystalline silicone cells or thin-film cells based on Cd telluride or Si. The cells must so be connected electrically to one another and to the remainder of the system. These electrical connexions can be made in two ways. They are made either in series to accomplish a coveted end product electromotive force and/ or in parallel to supply a coveted current beginning capableness. A Silicones can be used in two applications during the fabrication procedure. First they are used for sealing the cell into the frame and secondly as an alternate method to ethylene vinyl ethanoate for encapsulating the solar cell.Coevalss of Solar cellsIn the last few old ages several new photovoltaic engineerings have been researched, with an purpose to happening as effectual alternate to silicon-based solar cells. The research and development in this country by and large aims to supply higher efficiency and lower costs per W of electricity generated. Some in the solar cell industry place different â€Å" coevalss † of solar cell engineering. First coevals solar cells: Solar cells made o semiconducting p-n junctions. Second coevals: Solar cells: Solar cells based on first coevals cells bur focussed on cut downing the cost f the same by using thin movie engineerings. Third coevals: The 3rd coevals is slightly equivocal in the engineerings that it encompasses. Generally it tends to include among others, PV cell systems utilizing multi-layer ( tandem ) cells made of formless Si or Ga arsenide, non-semiconductor engineerings ( including polymer-based cells and biomimetics ) , while more theoretical developments are still in consideration. These include frequence transition, hot- bearer effects and other multiple-carrier expulsion, quantum point engineerings, dye-synthesized solar cells and upconversion engineerings. Presently the theoretical upper bound of the transition of sunshine to electricity is 33 % for a standard solar cell. But the Carnot bound for the same is about 95 % . This opens up a window of chance for heightening the efficiency of solar cells two or three times provided that assorted constructs can be put into usage for bettering efficiency without bearing high costs. These cell engineerings have the possible to get the better of the Shockley-Queisser bound of 31-41 % power efficiency for individual bandgap solar cells. This is what has been attempted by 3rd coevals solar cells, alternate stuffs to tackle the solar energy. 10 Innovalight is one of the Bay Area-based Startups that have pioneered the development of silicon nanoink-based solar cells. Beginnings claim, lab efficiencies are every bit high as 36 % .Current Use of Solar PowerPresently Solar energy is going progressively popular due to its sustainability, its little demand for care and its long term cost-effectiveness. 8 Presently the energy collected via the Sun is put to many utilizations. The chief beingWaterPart of the solar energy harnessed is used to pump H2O in distant countries. In peculiar it is used to power off-grid desalinization workss. Industry Solar energy has been used to power Television and wireless repeater Stationss, which are automated Stationss that transmit signals ) . It is besides used to power beacons, buoys and aircraft warning visible radiations on edifices and other constructions. Heat Solar energy can be used to heat residential places, whereby the energy is used to heat the H2O supply and, peculiarly in Florida, swimming pools are heated in this mode. â€Å" A photovoltaic cell is installed on the roof to roll up solar energy and is used to warm a heat transportation fluid that is used to heat the H2O itself. †Transportation systemâ€Å" Increasingly, solar energy is being used to power public transit vehicles such as coachs, streetcars and light-rails. Plans for solar-powered coach shelters are in the plants every bit good † .Consumer MerchandisesSmall appliance, such as reckoners and tickers, frequently use solar energy. Life Span Current solar cells have as effectual life span of approximately 20 to 25 old ages. Their value and electrical power end product lessenings steadily over clip. This occurs due to have on and rupture of usage. As the outer protective coating of glass wears off the internal constituents go more susceptible to damage.20Theory: SiliconesSiliconesDefinition: SiliconesA are inert, man-made compounds with a broad assortment of signifiers and utilizations. They are typically heat-resistant andA rubber-like. 13FormationSilicones are formed by the transition of chlorosilane monomers into polymer merchandises. This normally involves 2-4 procedures Hydrolysis plus killing Acid decrease of the hydrolysate In some instances Conversion of hydrolysate to cyclic oligomers Polymerization Equilibration Or Bodying of the hydrolysate to cyclic oligomers Depriving Devolatilization Or Solvent remotion Hydrolysis is a chemical reaction in the procedure of which molecules of H2O are split into hydrogen cat-ions ( H+ , referred to asA protons for convenience ) and hydroxide anions ( OHa?’ ) , in the procedure of the chemical mechanism.A This is a type of reaction used to interrupt down certain polymers, specifically those made by a step-growth polymerisation. Such a procedure is normally catalysed either acerb or base. A common acid used is sulfuric acid ( H2SO4 ) , and a common base used is sodium hydrated oxide ( NaOH ) . 14, 15Silicon ProductionSilicon does non be on its ain in nature. Generally it is bonded with O, organizing stuffs such as sand and vitreous silica and granite stone. The silicon- O bond in vitreous silica is reputably so stable it can merely be broken by white heat. 9Silicon manufacturers cut down top-quality vitreous silica sand to elemental Si via a carbo-thermic smelting procedure: Formula for cut downing sand to elemental Si This reaction occurs in an electric furnace at & lt ; 1,400A °C ( & lt ; 2,600A °F ) . In it the C monoxide gas ( g ) leaves the furnace so the Si can non respond with the C to organize Si dioxide. The liquefied elemental Si, which is about 99 per centum pure, is so cooled and broken into balls. When used in silicone production, the Si is ground into a all right pulverization to increase the surface country available for reactions.Methylchloride productionMethylchloride is produced by distilling methyl alcohol with hydrochloric acid: Formula for distilling methyl alcohol with hydrochloric acid to bring forth methylchloride Two methyl groups ( CH3 ) must attach to each Si atom to bring forth one molecule of dimethyldichlorosilane. Dimethyldichlorosilane is the basicA silicone edifice block. 9Synthesization of chlorosilanesChlorosilanes are synthesized in a fluid bed reactor at temperatures runing from 250 to 300A °C ( 482 to 572A °F ) and at force per unit areas of 1 to 5 bars. The methyl chloride ( CH3Cl ) flows through a fluidized bed of Si metal powder.9 The reaction, is catalyzed by a copper-based accelerator, generates a complex mix of methyl chlorosilanes: Formula for the chlorosilanes synthesis reaction The methyl chlorosilane mix contains: A big sum of dimethyldichlorosilane ( Me2SiCl2 ) – the primaryA edifice block A moderate sum of methyltrichlorosilane ( MeSiCl3 ) Some trimethylchlorosilane ( Me3SiCl ) A little sum of methyldichlorosilane ( MeHSiCl2 ) Plus smaller sums of other silanes The chlorosilanes are so separated from one another through the procedure ofA distillment.Distillation of chlorosilanesDistillation is a procedure in which a liquid undergoes two stage alterations. One in which it transforms from a liquid to a gas and a 2nd where it reforms into a liquid. Each of the chlorosilanes produced during theA synthesisA phase has a alone boiling point. These boiling points are used to purify the chlorosilanes from one another based on the figure of Cl atoms attached to the molecule. Because the boiling points of the assorted chlorosilanes are so near together, really tall distillment columns are required to divide them. Once separated, the chlorosilanes are ready to be turned into utile siloxanes through the procedure ofA hydrolysis and condensation.9Hydrolysation and Condensation of ChlorosilanesFirst H2O is added to dimethyldichlorosilane ( the principal chlorosilane ) , as this done the two react to organize disilanol and hydrochloric acid. This occurs because O feels a greater attractive force for Si than Cl ; and chlorine feels a greater attractive force for H than O ( Me = CH3 ) . 9 demand elevations text The disilanols formed are unstable and strongly attracted to one another. These are so catalyzed by the hydrochloric acid, where they condense into polydimethylsiloxanes -which are molecules incorporating a anchor of Si atoms bonded to oxygen atoms. Hydrolysis and condensation occur spontaneously, at the same time, and really rapidly. These reactions are a regular â€Å" ageless chemical science machine, † ensuing in a mixture of: Cyclic ringsA ( with 3-6 reiterating SiO units ) Linear chainsA ( with 30-50 reiterating SiO units ) The cyclic and additive oligomers ( mini-polymers ) are separated from one another and distilled into cuts based on the figure of SiO units in the concatenation. Some are used as they are ( cyclosiloxane and low-molecular-weightA silicone fluids, for illustration ) . But the bulk are furtherA polymerized and finishedA to make a broad array of stuffs with an astonishing scope of public presentation capabilities.16Silicone PropertiesSilicones can be considered a molecular loanblend between glass and organic additive polymers. In which if as Si atom is bonded merely to oxygen atoms the construction formed is an inorganic glass called a Q-type Si. If one O atom is replaced with an R-group, such as a methyl, ethyl or phenyl, so a rosin or silesquioxane, or T-type Si, is formed. This type of stuff is more flexible than a Q-type stuff. Hereafter if two O atoms are replaced by organic groups, so the ensuing stuff formed is a really flexible additive polymer, known as D-type Si.19 This increased flexibleness found with diminishing cross-linking consequences in a low glass passage of the additive polymers. Due to this low glass passage silicones typically besides have a low modulus one time formulated and cured, specifically when compared to organic polymers. The modulus in additive silicones can be rather low by and large due to low crosslink denseness and in this signifier silicones frequently function to alleviate emphasis due a mismatch of coefficients of thermic enlargement, between two constituents in many applications. 19Derived MerchandisesLubricants: Silicones are used to deduce a dry-set lubricator is delivered with a dissolver bearer to perforate the mechanism. The solvent evaporates go forthing a clear movie that lubricates but does non pull soil and grit every bit much as traditional â€Å" moisture † lubricator. Assorted silicones are used as several types of lubricating oils. They are used for bike ironss, air-soft gun parts and a broad sc ope of other mechanisms. Poting: Potting is a procedure InA electronics in which a complete circuit assembly is filled with a solid compound for opposition to floor, and quiver, and for exclusion of wet and caustic agents.17 Silicone is frequently used as a potting agent. Encasing electronic equipment in this mode improves the stableness of the equipment against, mechanical daze, electrical daze, radiation, and quiver. Other utilizations of silicone include Rainproof coatings: Silicone movies can be applied to silica-based substrates like glass used as a signifier of insularity. Fabrics may be coated or impregnated with silicone to organize a strong, rainproof complex such asA silnylon. Besides silicone caulk can be used as a basic sealer against H2O and air penetration.http: //upload.wikimedia.org/wikipedia/commons/thumb/3/37/Caulking.jpg/160px-Caulking.jpgSilicones as Solar EncapsulantsLED, Photovoltaic and other light sensitive devices require UV stable non yellowing encapsulants for protection and improved light transmittal. Optically Clear Silicones are best suited to this type of operation. These can be found in different scopes of hardness, viscousness, mix ratio, room temperature remedy, and heat remedy. This allows them to be adaptable and to run efficaciously in different conditions.Protection offered by SiliconesSolar cells are presently being implemented in parts every bit diverse as Germany and the Sahara. In consequence this means that the silicones need to be able to offer protection against really diverse inauspicious climes. Silicones need to be able to protect against the effects of sustained rain showers such as those happening in Asia, during monsoon season, while besides being able to prolong continual harm caused by desert air currents. Following this Protection is besides required from the effects of continual alterations in the clime. One illustration of the gradual wear of stuff is due to Aeolian or wind eroding. This type of eroding occurs about chiefly in the desert, where many industrial graduated table solar workss are installed.18ConsequencesFrom my research I have gathered that: Current solar engineering relies to a great extent on p-n junction photovoltaic cells. The current coevals of solar engineering is being implemented across Europe, in the United States of America, and major plants are being carried out in the African comeuppances. Current solar cells use a glass window glass as a screen for the external screen of the solar cell. The mean life span for a solar cell is between 20 and 25 old ages. Silicones have the advantage of being really versatile in their formation. They can be formed to accommodate the environment in which they will be implemented. There is possible in the current solar cell market for silicones to be used as screens, or coatings for PV faculties.DecisionsWhy Silicones and the PV faculty assembly market are perfect for each other:Mechanical belongingss that stay about changeless over a broad scope of temperatures & A ; remain about changeless over a broad scope of temperatures. UV stableness Low Equilibrium wet content Electrical insularity Fire opposition Hi degree of adhesion Optical transparence Silicones are an ideal merchandise household to run into the demands in the PV faculty assembly market. Their citations include mechanical belongingss that remain about changeless over a broad scope of temperatures, and remain stable even after long periods of exposure at high temperatures. UV stableness, low equilibrium wet content, electrical insularity, and fire opposition are built-in in silicones due to their chemical nature. In add-on to this decently formulated silicone preparations can exhibit really fast remedy rates, high degree of adhesion to many hard- to stick-to substances, and optical transparence. All of these contribute to high lastingness in out-of-door exposure, and higher efficiency due to more effectual usage o the visible radiation from the solar spectrum. In the UV-visible wavelength part silicones are extremely crystalline, this makes them ideal campaigners for cell encapsulants. They can be formulated to hold low modulus and be stress alleviating piece besides holding first-class adhesion to the glass and cell substrates.RecommendationsFrom my research carried out in this country of survey it is my recommendation that silicones be used as the criterion method for encapsulating PV cells, and thereby PV faculties. The current PV cells comprise chiefly of p-n junction solar cells, the general layout and design of which was discussed earlier in the study. Silicones would do a really suited covering/ encapsulant for these types of solar faculties as they can be formed into extremely flexible stuff that can easy surface the outer bed of the faculty. Once on the stuff the silicone can so be hardened/ solidified to organize a lasting coating on the PV faculty. The silicone coating can so efficaciously protect the constituents of the PV faculty from external harm caused by corrosion. This efficaciously means protection from the effects o weather corrosion, such as wear and tear caused by the rain, Sun etc†¦ †¦ As silicones offer protection from all of the above they are ideally situated to be used as solar encapsulants.
