Anisotropic compressive response of Stone-Thrower-Wales defects in graphene: A molecular dynamics study G. Rajasekaranï€ ª and Avinash Parashar Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee - 247667, India ABSTRACT: The mechanical properties of graphene sheet can be tailored with the help of topological defects. In this research article, the effects of Stone-Thrower-Wales (STW) defects on the mechanical properties of graphene sheet was investigated with the help of molecular dynamics (MD) based simulations. Authors has made an attempt to analyse the stress field developed in and around the vicinity of defect due to bond reorientation and further systematic evaluation has been carried out to study the effect of these stress fields against the applied axial compressive load. The results obtained with the pristine graphene were made to compare with the available open literature and the results were reported to be in good agreement with theoretical and experimental data. It was predicted that graphene with STW defect cannot able to bear compressive strength in zigzag direction, whereas on the other hand it was predicted that graphene sheet containing STW defect can bear higher compressive load in ar mchair direction, which shows an anisotropic response of STW defects in graphene. From the obtained results it can be observed that orientation of STW defects and the loading direction plays an important role to alter the strength ofShow MoreRelatedEffects Of Point And Line Defects On The Properties Of Graphene9719 Words   |  39 PagesEffect of Point and Line Defects on the Properties of Graphene: A Review Rajasekaran G, Prarthana Narayanan and Avinash Parashar* Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee - 247667, India * Corresponding author: E-Mail: drap1fme@iitr.ac.in, Ph: +91-1332-284801 ABSTRACT New materials with distinctive properties are arising and attracting the scientific community at regular intervals.

Comic Relief Free Essays

Kaylee King Per. 2 Comic Relief Shakespeare’s element of comic relief in his plays provides more than just mere pieces of entertainment for the groundlings; it allows a break from the dense and sometimes evil continuity of the play. Comic scenes provide relief to the audience while building up the intensity from earlier scenes. We will write a custom essay sample on Comic Relief or any similar topic only for you Order Now Sometimes appearing out of place within the play, the scenes and characters are still significant roles in advancing the play. In Shakespeare’s Hamlet comic relief is supplied throughout the plot through the character of Polonius. Polonius, a foolish old man with a lot to say, is able to produce the amount of relief necessary to his audience. With his long speeches and pleasing manner, Polonius sets a certain tone towards the entirety of the play. Time and time again he gives the old â€Å"when I was your age speech† and assumes the role of a parent to everyone, giving his unwanted and disregarded opinion. When a player about the death of Priam makes a deep and eloquent speech, Polonius interrupts by simply saying, â€Å"This is too long. † This being said was entirely ironic because of the long and seemingly pointless speeches that Polonius dishes out to anyone able to hear. Shakespeare’s use of Polonius as a comic character is significant towards the overall tone of the play. The depressing and death filled play needs a comic way to show its tragic nature through a sort of dark humor. Hamlet’s many remarks regarding death and old age towards Polonius is a prime example of this. Polonius being the foolish elderly man he is, provides an easy target for Hamlet so called ‘humor. ’ Jokes of murder and death, although humorous, provide an edge of darkness to the tone of Hamlet.

Jewish Philosophy And Social Work Essays - Emotions, Loneliness

Jewish Philosophy And Social Work Jewish Social Philosophy For centuries, mankind as a whole has always desired or searched for love at some given point if not for their entire life span. Love is a concept that while the dictionary will give you various definitions, can not really be defined, but rather felt. Even if we believe we are experiencing feelings of love at some point, there is no guarantee that the experience then is an ever-lasting true love. Love grows and changes throughout ones life starting hopefully with ones parents leading to peers, and on to life partners. Over time, many philosophers have looked into this topic, trying to explain and break down what exactly the concept is. It is the object of this paper to look at both Soleveichick as well as Maimonedes, and apply their views to both a modern day perspective and social work. Love being a concept that has been around since the beginning of time according to some may have been a divine idea. If you look at the way Soleveichick breaks down the character of first man into Adam I and Adam II, I think my point can be clearly seen. According to Soleveichick it seems that Adam I is the utilitarian character by action and attitude, I will return to him later. Adam II on the other had is an existential character by his nature. By that it seems to mean that Adam II in the case of love would be the more romantic character, the one which many at some point of life desire this type of a loving relationship. This is the character where love comes truly within; it is a spiritual kind of love, where one really needs nothing in return but the love itself. In todays standards these are the people one would just buy flowers for, take long walks on the beach with, as well as exploring and experiencing issues as well as acts of intimacy with. These are the people we desire as life partners (does not necessarily have to be for a marital type of relationship.) at times. I know that from my personal experience at this point in my life I am having my first experience of true love other than the parental one I had. The person I am referring to is now my fianc?e. The feeling I have towards her are ones of total joy which run through my body, that words can not do justice. It is that burning desire within to constantly see, be with, and hold on to her. For me I believe that it is mostly an Adam II type of a relationship we are having. Of course love in this manner for different people can have different feelings as well as meanings, after all every man has their own characters. Another thing derived from the character of Adam II that it was Gods intention to find someone they love and eventually spend the rest of their lives with this person. Maybe God was even saying in a way that one can not go through life and be complete without a partner. I quote in Genes is (chapter 2 vs.22-23) and he took one of his sides and he filled in flesh in its place. Then Hashem, God fashioned the side that he had taken from man into a woman. Not only did this end first mans utilitarian loneliness, it also may have been showing us how we should feel about a loved one. The second person whether she was actually created from the first persons rib or side is unimportant. What one can derive from this is that not only was there a creation made at this point but a strong bondage as well, bonding man to his fellow man. Scripture seems to be saying that when we love someone it should be as if they are in fact a part of ourselves, as if they are physically attached to us. It seems Gods doing the creation in this manner was giving an important message. It seems to be saying that an individual can not lead a healthy, comfortable life without sharing it with love ones. We see that first

Impact of Aids in Africa essays

Impact of Aids in Africa essays By the end of 1996 the estimated number of people living with HIV/AIDS in the world was 22.6 million. Of that number, 14 million, accounting for nearly two-thirds of the total, were in sub-Saharan Africa (Wehrwein, 2000). Nearly two decades into the outbreak, the epidemic has spread throughout the sub region. While the epidemic has apparently peaked in parts of Uganda and the Democratic Republic of Congo it is still rising in parts of Kenya and Southern Africa and is yet to become a major problem in most countries in West Africa. Clearly, HIV/AIDS has become a major public health problem and human crisis in Africa, straining heavily on health care and social service resources far beyond the capability of these sub-Sahara African countries (Wehrwein, 2000). In Africa, HIV/AIDS account for more than 50% of all adult admissions to hospitals, in addition to a significant number of pediatric admissions. The overall effect of HIV/AIDS on the social infrastructure in sub-Sahara Africa is staggering. Africa is seriously handicapped to deal with this disease. Most of the African government policies and programs are not adequately addressing the peoples need to combat this disease. Presently, the disease has overwhelmed the public health system in Africa. The social environment in Africa offers very little support for individuals infected with HIV/AIDS. Africa is seriously disadvantaged when it comes to establishing adequate programs that will address the needs of pregnant mothers/women infected with HIV, childr en born with HIV, and orphans who live in Africa. Since many economies in African countries are in flux, it is very difficult to determine the impact of AIDS on each countrys economy. However, it has been documented that this disease has multiple and complex effects on sustainable human development in sub-Sahara Africa. Due to the diseases erosion of the human resource base, the countries of Africa have...

How to Study for SAT Subject Tests 5 Expert Tips

How to Study for SAT Subject Tests 5 Expert Tips SAT / ACT Prep Online Guides and Tips Are you taking an SAT Subject Test soon and want to know how to be well prepared on exam day? You've come to the right place! In this guide, I explain everything you need to know about how to study for SAT Subject Tests, including which exam(s) you should take, the five most important steps for preparing for a Subject Test, and additional tips to help you maximize your score. This guide can be used to help you prepare for any and all of the 20 different Subject Tests offered, so let’s get started! Introduction to SAT Subject Tests Before we get into how to prepare for SAT Subject Tests, let’s go over some basic information on them. SAT Subject Tests are meant to measure your knowledge and skills in a specific area. This is in contrast to the ACT and regular SAT, both of which assess multiple subject areas.Some colleges require or recommend that you submit Subject Test scores when you apply to that school so they canget a better idea of your academic abilities. Each SAT Subject Test is an hour long, has 50-95 multiple-choice questions, and isscored on a scale of 200-800. SAT Subject Tests are offered several times a year, on all the same dates as the general SAT except for March. This means that SATSubject Tests are offered in the following months annually: May June August October November December However, not every Subject Test is available on every date. Check out our guide to learn the exact dates each Subject Test is offered.In most cases, you can take up to three Subject Tests in one day. Which SAT Subject Tests Should You Take? Before you can begin preparing for SAT Subject Tests, you need to decide which ones to take. The College Board offers 20 different SAT Subject Tests infive main areas. Here is the full list: English Literature History US History World History Languages Chinese with Listening French French with Listening German German with Listening Italian Japanese with Listening Korean with Listening Latin Modern Hebrew Spanish Spanish with Listening Mathematics Mathematics Level 1 Mathematics Level 2 Science Biology E/M Chemistry Physics The most important factor when deciding which Subject Test to take iswhat the colleges you’re thinking of applying to require or recommend. Some schools want you to take Subject Tests in the area you plan on majoring in, whereas others want one Subject Test score from Math/Science and another from Literature/History to show that you’re well rounded. In addition, some schools require or recommend only one Subject Test score, whereas others expect two or three. Be sure to research this information before you begin studying so you don’t end up preparing for and taking a Subject Test you didn’t actually need to take! The other factor to consider is which subject areas you are best in and/or enjoy the most.For example, if you did well in your chemistry class at school and need a science SAT Subject Test, you might want to consider the Chemistry Subject Test. Finally, it’s often easier to do well on Subject Tests that are closely related to classes you've already taken, especially AP classes. If you just took AP World History and studied a lot for the AP exam, you might not need to do much studying at all in order to prepare for the World History SAT Subject Test, especially if you take it in May right after your class ends. How to Study for SAT Subject Tests After you’ve figured out which SAT Subject Test you’ll be taking, follow these five steps in order to prepare for the exam. These steps cover everything you need to do from the time you begin studying up until test day. Step 1: Take an Initial Practice Test One of the first things you should do istakea full-length practice exam for the Subject Test you’re planning to take.Once finished, complete and score your practice exam to see how well you did. For more tips on how to find high-quality practice exams and how to take a practice test most effectively, check out the "How to Use Practice SAT Subject Tests Effectively" section below. Aim to get higher than the average score for that SAT Subject Testfor the most competitive school you’re applying to.You can sometimesfind average Subject Test scores on the admissions page of a school’s website. If you can’t find this information, though, consider contacting the school directly. You can also check outthe average score for each Subject Test. Ourguide shows you how well test takers do on each SAT Subject Test. But ifyou’re applying to a particularly competitive school, you’ll likely have to aim higher than just the average test score depicted on the chart. Try to aim for the top 25% of test takers, or even the top 5% if you’re applying totop-tier schools. Step 2: Decide How Much You Want to Study Once you have your practice test score, see how far it is from the goal score you’re aiming for. If your practice test score is pretty close to the score you’re hoping to get on the real Subject Test, you might only need to do light studying between now and the exam. If you have some ground to gain, you’ll likely want to do some more serious preparation. Keep reading to find out exactly what you'll need to do. Step 3: Gather the Materials You Need Now, it’s time to start gathering the materials you need to prepare for your SAT Subject Test.Study materials can include class notes as well as review books specifically focusing on the Subject Test you're taking.There are a lot of review books out there, but some of the most popular are those produced by Barron’s, Kaplan, and The Princeton Review. The College Board also offersofficial study books for some of the more popular Subject Tests, such as Math Level 1, Math Level 2, US History, and World History. However, these books are mostly just practice exams and explanations of answers as opposed to thorough content reviews. Visit the College Board's online store for a full list of SAT Subject Test study guides(or scroll down to the next section!). Alternatively, you might want to buyThe Official Study Guide for All SAT Subject Tests, which (as you probably guessed) providesan overview of the Subject Tests, quality practice questions, and one full-length practice test per exam.At present, the book sells for around $10 on Amazon. Finally, we at PrepScholar have created specific study guides to help you prepare for the Biology, Chemistry, Literature, Physics, US History, and World HistorySAT Subject Tests. Step 4: Create a Study Plan Developing a prep plan is important because it helps you commit to study times and track your progress.Try to set aside the same time to study each week, such as 2-4 pm on Sundays or 5-6:30 pm on Tuesdays and Thursdays.This will make it easier to remember when to study and allow you to plan other activities around your prep sessions. You should also set weekly or monthly goals you hope to accomplish. This will help track your progress and ensure you’re where you need to be. Example goals include things such as "I want to understand properties of functions by the end of the week," or "I want to raise my score 20 points by the end of the month." Be sure to also schedule time to take practice tests and track your progress. Ideally, you’ll take at least two practice tests before the real deal, with one at the beginning of your studying and one at the end. If you’re studying a lot or over a long period of time, you might want to schedule one or more additional practice tests during the middle of your studying. Step 5: Start Studying! Now, it’s time to get down to business and begin studying! When you’re reviewing material, your best bet is usually to use your prep book as your main resource,and use your class notes for any topics you want more in-depth information on. Trying to review all your class notes for a subject can be very time consuming and possibly not that helpful if your class didn’t focus on the same topics the Subject Test focuses on. Prep books, on the other hand, are specifically designed to focus exactly on what the Subject Test covers.Below, we give you more information about how to use practice tests as well asfinal tips for studying for SAT Subject Tests. How to Use Practice SAT Subject Tests Effectively Practice tests are one of the most important tools in helping you reach your SAT Subject Test score goals, so you want to use them wisely. These three guidelines will help you do just this. Stick With High-Quality Tests Your practice test results are only as good as the quality of the practice test itself.If your practice test isn’t very similar to the real Subject Test, you won’t be getting an accurate idea of how well you’re scoring or what skills you should improve. Practice tests from the College Board are the best sources to use since you can be sure they’ll give you a good idea of the real exam. As I mentioned above, the College Board'sThe Official Study Guide for All SAT Subject Testsincludes one previously administered exam for each of the 20 Subject Tests. So if you’re planning to take multiple Subject Tests, this is a great resource to use. There are also official prep books for the seven following SAT Subject Tests: Math Level 1 Math Level 2 US History World History Chemistry Biology Physics Unofficial practice books that are still high quality include those produced by Barron’s, Kaplan, and The Princeton Review. There are other resources out there, too, so it can help to go to a bookstore and flip through a few books or read online reviews to decide which resource is best for you. Take the Test Under Real Test Conditions In order to get the most accurate idea of where you're currently scoring on your SAT Subject Test, you need to make sure your practice test conditions are as realistic as possible.This means taking the test in one sitting, timed (each Subject Test is an hour), and with no distractions. Track Your Progress Tracking your practice test scores over time is one of the best ways to see whether and where you’ve made improvements. Almost every practice test has instructions on how to calculate your score, but if you get confused, you can alwayscheck out our guide for a review.Unlike the general SAT, for SAT Subject Testsyou lose a fraction of a point for each question you answer incorrectly, so too many random guesses could very well bring down your score. Here's how scoring works for Subject Tests(all the Subject Tests except the foreign language tests have five answer choices. Foreign languages tests have four answer choices): You get 1 point for each correct answer. A fraction of a point is subtracted for wrong answers: 1/4 point is subtracted for five-choice questions. 1/3 point is subtracted for four-choice questions. 1/2 point is subtracted for three-choice questions. No points are deducted for questions left blank. If yourfinal score is a fraction, it's rounded to the nearest whole number - 1/2 or more is rounded up; less than 1/2 is rounded down. If you aren’t improving as much as you want to, try using different prep resources or changing up the way you study. It might be helpful to focus more on taking practice tests, study at a different time or day, or use other study methods such as flashcards. 3 Tips for Getting Your Best SAT Subject Test Score Now that we've thoroughly covered the basics of how to study for SAT Subject Tests, here are three advanced tips to helpyou get your best score. Know Your Learning Style There is no one-size-fits-all study plan, and the best way to see the results you want is to use your learning style to your advantage.Maybe you’re a visual learner and need to see diagrams, charts, and images for the information you’re learning to sink in. Or perhaps you’re an auditory learner and learn best with audiobooks or podcasts. You might already know what your learning style is, but, if not, try out different methods of studying and see which work best. You can also alter the day of the week, time of day, and length of time you study to see if that makes any difference. Don't Passively Study It might be easiest to let your eyes drift over the pages you’re studying, but this rarely gets you the results you want.Try to make your studying as active as possible. This might mean drawing diagrams, making flashcards, having a friend quiz you, or even just pausing every few minutes to review what you’ve read and ensure you’re actually retaining the information. The less passive your studying is, the more likely you are to see significant improvements. Zero In on the Areas and Skills You Need to Improve When preparing for an SAT Subject Test, make sure you’re spending most of your time on the areas and skills you need to improve the most. If you’re studying for the World History Subject Test and are solid on European history but struggle with Asian history, don’t spend an equal amount of time reviewing Europe and Asia. Instead, you’ll want to spend more time focusing on important Asian events, periods, and people, and only come back to Europe for a quick, occasional review to make sure you still remember everything. By spending the majority of your time on the areas where you have the most room to improve, you’ll likely see score improvements more quickly. Summary: How to Study for SAT Subject Tests If you want to get top scores, you have to understand how to prepare for SAT Subject Tests.Follow these five steps in order to be well prepared for any Subject Test: Take an initial practice test Decide how much you need to study Gather the materials you need Create a study plan Start studying! Additionally, remember to use your practice tests effectively, practice active studying, and focus most of your time on the areas you need to make the biggest improvements in. What's Next?

Overview of Marketing and Information Systems II Research Paper

Overview of Marketing and Information Systems II - Research Paper Example hnique and the procedure that are used for gathering, designing, analyzing and presenting the information that can be used in making the decision of marketing (Wrenn & Et. Al., 2006). Consumers are not only the purchaser of economic goods but they are the main fulcrum of business who adopts potential of free services, philosophies or ideas. Consumer behavior is basically a decision making process that the individuals engage themselves in when making a decision with regards to acquiring, evaluating, using or disposal of the goods after usage (Tyagi, 2004). The tutorial begins with the definition of marketing as well as the short history of marketing. The business buying behavior has been taught in the next section which tries to focus about the business market primarily and it comprises of the organizations that are basically into manufacturing, distribution of the product and services. It is because of the huge market which has been successful in drawing attention of thousands of companies. The tutorial proposes that the understanding of the business market is quite easier in comparison to the understanding of the consumer market. In case of consumer market, there is need to build a recognizable brand which is not very important in case of business market. But there are many cases which prove that business buying is more important than consumer buying. Therefore in this section called business buying behavior, the tutorial tries to focus more on the characteristics of business buying behavior. The tutorial also teaches what exactly s upply chain is. It teaches that supply chain is mostly involved in activities relating to creation of the product and delivery to the final consumers. The tutorial also emphasizes upon the ways to deal with the customers effectively and to understand the buying behavior of the customers and the methods employed by the companies to understand the decision process of the consumer. It also discusses the various factor that affect the
