Roommate of a Lifetime

Roommate of a Lifetime Having a roommate freshman year is a total roll of the dice if its someone you dont even know. Just a couple months before move-in, my roommates name popped up on the computer screen. From then on, I knew Jehlani was my roommate. I didnt know what to expect, but on the first day of school, Jehlani and I clicked and have been clicking ever since. Late nights of talking and sharing stories, quick runs to Green Street for food, and someone who has been there through all the ups and downs is how Jehlani and I have connected through our time of knowing each other. Jehlani and I never seemed like the likeliest of friends because he was from the city and I am from the country, but when we are chilling together, none of that even matters. I know I can count on him for anything and everything because we always have each others backs. I cannot express how great it is that I found someone who can be such a fantastic friend in college. Your time in college is going to be filled with uncertainty and the adventures of mixed emotions. A lasting friendship is what can anchor this entire experience. I was certainly glad to have a roommate that I could call a friend, but even more so, I am thrilled that we have remained friends since our time as roommates ended. I write this post because I hope that everyone can come to college and find a friend like Jehlani. In many ways, this friendship has been one of the most valuable things that I have gained from my time in college so far. In college, dont try to make just any connection; make the connections that will matter. Jacob Class of 2019 I’m an Advertising student within the College of Media. My hometown is a place called Fairmount, Illinois, which is about 30 minutes from campus. I began my Illinois journey in the Division of General Studies.

Using the Spanish Verb Pensar

Pensar typically means to think, but it is not always used in the same way as the English verb. Most significantly, the words that follow pensar might not be the ones you would expect. Keep in mind that pensar is conjugated irregularly. When the stem pens- is stressed, it becomes piens-. Thus, the present indicative forms are pienso (I think), piensas (you think), piensa (he/she/you think), pensamos (we think), pensà ¡is (you think), piensan (they/you think). Here are the main uses of pensar: Using Pensar by Itself Most frequently, pensar, when used by itself, is the equivalent of to think. Pienso, luego existo. (I think, therefore I am.)No pienso mal de ellos. (I dont think bad of them.)El que piensa demasiado siente poco. (The one who thinks too much feels little.) Using Pensar Que Pensar que is a very common way of indicating opinions or beliefs. It often is translated appropriately as to believe rather than to think. In the positive form, it is followed by a verb in the indicative mood. Note that while que in this usage usually can be translated to English as that, it often can be left untranslated, as in third and fourth examples. Pienso que vivo como un cerdo. (I think that I live like a pig.)Mi madre piensa que el doctor es culpable. (My mother believes that the doctor is at fault.)No quiero pensar que me equivoquà ©. (I dont want to believe I made a mistake.)Tambià ©n pensà ¡bamos que la recuperacià ³n econà ³mica iba a ser mà ¡s rà ¡pida. (We also used to believe the economic recovery was going to be quicker.) When used negatively, no pensar que is followed in standard Spanish by a verb in the subjunctive mood. It is not unusual, however, to heard the indicative mood used in casual Spanish. No pienso que seamos diferentes. (I dont believe we are different.)No pensà ¡bamos que fueran a darnos problemas. (We didnt think they were going to give us any problems.)Mis amigos no piensan que yo tenga mà ¡s de 21 aà ±os. (My friends dont believe Im more than 21 years old.) Using Pensar De Pensar de is another way to say to have an opinion about. Esto es lo que pienso de tu regalo. (This is what I think about your gift.)Tenemos que cambiar de lo que pensamos de nosotros mismos. (We need to change what we think about ourselves.)Ya he indicado antes lo que pienso de la clase. (I have already indicated what I think about the class.)No es bueno preocuparse por lo que los otros piensan de usted. (It isnt good to worry yourself about what others think about about you.) Pensar sobre can also mean to have an opinion about, especially when used in a question. Pensar de is more common.  ¿Quà © piensas sobre la nueva web? (What do you think about the new web site?) ¿Quà © piensan sobre los ataques suicidas como instrumento tà ¡ctico para ser utilizado en una guerra? (What do they think about suicide attacks as a tactical instrument to be used in a war?) Using Pensar En When followed by en, pensar typically means to think about in the sense of having ones thoughts focus on something. Note that this isnt the same as using to think about in the sense of having an opinion. Estoy pensando en ti. (Im thinking about you.)Pablo no piensa en los riesgos. (Paul doesnt think about the risks.)Las chicas sà ³lo piensan en divertirse. (The girls think only about having fun.)Nadie piensa en cambiar las baterà ­as. (Nobody thinks about changing the batteries.) Pensar sobre can mean basically the same thing as pensar en but is much less common and is probably overused by English speakers speaking Spanish as a second language or when translating from English to Spanish. Pienso sobre eso dà ­a y noche. (I think about it day and night.)Primero hacen y luego piensan sobre ello. (First they acted, and then they thought about it.) Following Pensar With an Infinitive When followed by an infinitive, pensar is used to indicate plans or intentions. Pensamos salir maà ±ana. (Were intending to leave tomorrow.)Yo pienso estudiar medicina de veterinaria en la universidad. (Im planning on studying veterinary medicine at the university.)Pensaron salir de Venezuela, pero decidieron permanecer. (The were planning to leave Venezuela, but they stayed.)

Khaled Hosseinis The Kite Runner Essay - 1008 Words

Khaled Hosseinis The Kite Runner In the Kite Runner, the author explores the ties that bind sons to fathers and childhood friends to one another and of the forces that tear them apart. Throughout the novel, Khaled Hosseini uses many literary devices such as parallelisms, and characterization, and symbolism. The main message is â€Å"there is a way to be good again.† Amir is continuously changing throughout the story as he narrates†¦show more content†¦In the novel The Kite Runner two of the major themes are redemption and atonement. These themes mean the ability for people to repair or fix past sins or mistakes. People can often achieve redemption by righting past wrongs. This theme is clearly shown in this novel, mainly by Amir. As a child Amir betrayed and was disloyal to Hassan, when he did not help him when he got sexually assaulted. Amir is able to right his past wrongs against Hassan by saving Hassan’s son Sohrab. Redemption, although may sound easy, is hard for people to achieve, such as Amir. Redemption takes great character strength to believe that you can find a way to be good again. Amir could not face himself for what he did; therefore he was not able to forgive himself or redeem himself. Amir needed guidance and a push from a good friend to help him live his life guilt free and to achieve redemption. â€Å"There is a way to be good again, said by Rahim Khan, numerous times in the novel, shows this theme of redemption and atonement. Rahim Khan gave Amir the push that he needed to find atonement and for Hassan and himself to forgive. This shows that most mistakes can be fixed and forgiven.

Separation of a Mixture of Solids Free Essays

Separation of a Mixture of Solids My Flow Chart First remove iron filings with magnet since this is the only substance in the mixture that it is magnetic and will be attracted to a magnet. Second remove the sand by adding the mixture to hot water, which the other two substances are soluble. Third remove the benzoic acid since this is less soluble in cold than salt by cooling the mixture in the heated water. We will write a custom essay sample on Separation of a Mixture of Solids or any similar topic only for you Order Now This will then leave the table salt behind in the water as the last substance. Observations Data Table 1: Experiment Data| Grams (g)| Percent of Mixture (%)| Initial Mixture| 6. 5| 100| Iron Filings| 1. 8| 27. 69| Sand| 1. 7| 26. 15| Table Salt| 1. 9| 29. 23| Benzoic Acid| 0. 8| 12. 31| Combined Total| 6. 2| 95. 38| Questions A. How did your proposed procedures or flow charts at the beginning of this experiment compare to the actual procedures of this lab exercise? My proposed flow chart was very close to that of the actual lab exercise. The only step that I did not include was letting the water evaporate to find isolate the table salt. I suppose I was thinking that it would be estimated by process of elimination. However, I can now that this would not accurately show that true weight and is therefore not scientific. B. Discuss potential advantages or disadvantages of your proposed procedure compared to the one actually used. The disadvantage of my flow chart would be that although the end numbers would be closer to the original mass of the mixture, it would not accurately represent the correct percentages and would not account correctly show the rror that occurred during the process. C. How would you explain a sand recovery percentage that is higher than the original sand percentage? I would explain a sand recovery percentage that is higher than the original sand percentage from water that could still be let in the sand if it has not been given the proper time to fully dry. However, the a small amount of table salt and benzoic acid particle were also left behind in the small amount of water that needed to be dried out of the sand and could account for the higher percentage. D. What were potential sources of error in this experiment? I think that the largest potential for error is in the transfer and handling of the substances. Small particles were left behind in the original weighing dish, graduated cylinder and cup that were not able to be transferred. Human error, like spilling small amount of the mixture in transfer, and mechanical error, like a miscalculated calibration of the scale, could also be sources of error. How to cite Separation of a Mixture of Solids, Papers Separation of a Mixture of Solids Free Essays PURPOSE The purpose of this experiment is to become familiar with the separation of mixtures of solid and learn separation techniques based on the chemical properties of a substance. PROCEDURES 1. Separating out the Iron a. We will write a custom essay sample on Separation of a Mixture of Solids or any similar topic only for you Order Now Use your digital scale to determine the mass of your weighing dish. b. Empty the entire mixture of solids from the plastic bag into the weighing dish and determine the gross mass of the total mixture and weighing dish. Compute the net mass of the mixture: this is equal to the gross mass of the weighing dish with the mixture less the mass of just the weighing dish determined in 1-A. c. Spread the mixture into a very thin layer over a full sized piece of paper. d. Cut a second piece of paper into a 10-cm square. Weigh and record its mass and set it aside. e. Wrap a small square of clear plastic over the magnet. Remove the iron powder/filings by passing the magnet closely over the surface of the entire mixture. Repeat several times to make sure you’ve collected all the iron. f. Holding the magnet over the 10-cm square of paper, carefully remove the plastic and allow all the iron to fall onto the paper. Weigh and determine the net mass of the iron powder/filings. 2. Separating out the Sand a. Put the remaining mixture, containing sand, benzoic acid, and table salt into your beaker and add 50 mL of distilled water. b. Set up the beaker stand and burner fuel and heat the beaker of solids and water to near boiling. Stir the mixture to make sure all soluble material dissolves. At this point, the benzoic acid and the sodium chloride should have dissolved and been extracted from the insoluble sand. c. Decant (pour) the liquid while it is hot into a small paper or Styrofoam ® cup. d. Pour another 10 to 15 mL of distilled water into the beaker containing the sand, bring the mixture to a boil, and decant again into the same cup used in 2-C. This assures that any remaining salt and benzoic acid is removed from the sand. e. Make an ice bath by placing a small amount of crushed ice and tap water into a coffee cup or similar container that is large enough to hold your paper cup of benzoic acid and salt solution. Make sure the ice bath level is higher than the solution level but low enough so that no additional water can pour into the solution cup. f. Place the cup containing the water solution of benzoic acid and salt into the ice bath. Observe the benzoic acid crystallizing out of the solution as it cools. Set this water bath assembly aside until the next section. g. Heat the sand in the beaker over low heat until the sand is completely dry. Sand has a tendency to splatter if heated too rapidly. The possibility of sample loss can be reduced by covering the beaker with a small saucer and heating it very slowly. You might accomplish this also by placing the beaker in a warm oven. Alternatively, you may dump the wet sand onto a double layer of paper towels and let it air-dry. h. When the sand is completely dry allow the beaker to cool to room temperature. i. After the sand and any paper towels used are completely dry transfer the sand to a weighing dish of known mass and determine the net mass of the sand. . Separating out the Benzoic Acid: a. The benzoic acid crystals from Step 2-f above can be separated out by filtration. Use the following instructions to set up a filtration assembly: i. Weigh a paper cup and record the weight (mass). ii. Set the paper cup inside a slightly larger coffee cup or similar container to give the paper cup support and p revent it from tipping over when you add a funnel. iii. Fold a sheet of filter paper in half and then in half again as illustrated. Weigh it. iv. Open one section of the folded filter paper as shown in the bottom illustration. . Place the opened filter paper into the funnel and the funnel into the paper cup supported by the coffee cup. b. Remove the paper cup of salt and benzoic acid crystals from Step 2f from its ice bath. Fill a graduated cylinder with about 5 mL of distilled water and place the cylinder in the ice bath to chill the distilled water. c. Swirl the cup containing the salt and benzoic acid crystals to dislodge any crystals from the sides. Then, while holding the filter paper in place and open, pour the contents of this cup into the filter paper-lined funnel. d. After the sodium chloride solution has fully drained through the filter paper, slowly pour 2 to 5 mL of chilled distilled water around the inside surfaces of the filter paper-lined funnel to make sure all the sodium chloride has been removed from the benzoic acid crystals. e. After all the liquid has drained from the funnel lay the filter paper containing the benzoic acid crystals on folded layers of paper towels and put this someplace where it will not be disturbed while the filter paper and its contents air dry. Depending upon the humidity in your area this can take several hours or days. . When the filter paper containing the benzoic acid crystals is completely dry, weigh it and subtract the weight of the filter paper to obtain the net weight of the benzoic acid crystals. 4. Separating out the Salt a. Remove the funnel from the above filtration assembly and set the paper cup of sodium chloride solution someplace where it will not be disturbed while the water evaporates. Depending upon the humidity in your area this might take several days. When all the water has completely evaporated only sodium chloride will be left in the paper cup. b. Weigh the paper cup with the dried salt crystals inside and then subtract the weight of the cup to get the net weight of the table salt. c. Prepare a data table listing the various components of the mixture and record both their masses in grams to at least 1 decimal place, (i. e. , 0. 1 or 1/10th of a gram) and their percentage of the total mixture. 5. Cleanup: Thoroughly clean, rinse, and dry all equipment and return it to the LabPaq. Throw all used paper cups and paper towels in the trash. OBSERVATIONS, DATA, AND CALCULATIONS Part 1 Mass of weighing dish = 0. 5g Total mixture = 7. 5g Net mass of mixture =6. g Piece of paper =0. 8g Iron fillings + paper =2. 7g Net mass of Iron fillings = 1. 9g Part 2 Net mass of sand =2. 0g Part 3 Paper cup mass =6. 2g Filter paper =1. 0g Filter paper + benzoic acid =2. 7g Net mass of benzoic acid =1. 7g Part 4 Paper cup + salt =7. 1g Net mass of salt =0. 9g Data Table 1: Experiment Data GramsPercent of mixture Iron filings1. 927. 94 % Sand2. 029. 4 1 % Table salt0. 911. 76 % Benzoic acid1. 725. 00 % Total6. 595. 59 % QUESTIONS A. How did your proposed procedures or flow charts at the beginning of this experiment compare to the actual procedures of this lab exercise? It was similar to the procedure described. The only difference was the last step when separating out the Table Salt. I had proposed that we would have to heat the mixture instead of letting it evaporate. B. Discuss potential advantages or disadvantages of your proposed procedure compared to the one actually used. If heated, the salt and water mixture would not have formed any crystals and there would be a chance of losing salt with the excessive heat. C. How would you explain a sand recovery percentage that is higher than the original sand percentage? It would be explained by the possibility of some iron fillings, benzoic acid, or salt remaining in the sand and not separated properly. D. What were potential sources of error in this experiment? First, there were always remains that did not properly detach from the beaker or the stirrer. This occurred especially when separating out pure sand. Second, there is a possibility that some salt remained with the benzoic acid crystals and did not filter through the filter paper causing the mass of benzoic acid to be higher than expected and causing the mass of salt to be lower than expected. CONCLUSIONS This experiment was designed to teach separation of mixtures of solid and learn separation techniques based on the chemical properties of a substance. It utilized several techniques such as filtration, evaporation, crystallization, and separation. Overall, the experiment was very interesting; however, it was challenging at times. The salt water solution at the end took a very long time to fully evaporate and the masses did not add up to the total original mass indicating a loss of substance at some point in the experiment.

Lab Safety Initiatives

Question: Describe about charlies safety performance, safety issues and violations and recommended safety improvements? Answer: Charlies Safety Performance Charlie's performance regarding the safety in the laboratory was not satisfactory. He was least concerned regarding taking the precautions in the lab. He has a practice of taking short cuts in the works assigned to him to work fast and have ample time to work in a stress-free environment. His hygienic condition is also not good as he keeps a 2-inch beard and has long fingernails which are dirty. He does not even wash his hairs on a daily basis. He wears the lab coat and removes it after the evening shift Safety Issues and Violations The are several issues are as follows: Proper updating of the chemical inventory Discard of the chemicals namely, Glacial acetic acid and Sodium azide. Charlie does not wear gloves while withdrawing blood and keeps the needle holder in the jeans pocket. Keeping the tubes unlabelled and running the blood tests without any control. The practice of hanging the used lab coats with the clean coats. Recommended Safety Improvements The recommended safety improvements for these violations are the following: The chemical inventory must be updated according to the EHS Assist inventory system. It is a software for tracking the chemicals. The discard of chemicals should be done carefully, and a person who is disposing of it must see the MSDS (Material Safety Data Sheet) before disposing of the chemicals. Glacial acetic acid is a corrosive liquid and is hazardous. Sodium azide causes eye irritation and may be fatal if swallowed (Dikshith, 2013). The nurse, ward boys, and doctors should always wear gloves while drawing blood samples. The used needles should always be discarded in the biohazardous bin, and the needle holder should not be kept in the contact with the clothes and other belongings. The tubes containing the samples should always be labeled, and the tests should always run with the control. The used laboratory coats should never be hanged with the unused or clean ones because it increases the risk of contamination. The lab coats act as barriers in protecting the skin and the clothes of the individuals who perform tests and use hazardous chemicals (Panel, 2012). Charlie did not pay attention to the critical concerns of the laboratory. He was least concerned about taking the precautions. He only wanted to save his time by taking short cuts and work in a stress free environment. These issues cannot be neglected because any mishappening can lead to severe consequences related to the health of the patients as well as the individuals who perform these tests and handle the chemicals.

Palouse Falls

Palouse Falls Introduction and Background PaperIntroductionMy project area is Palouse Falls, which is located specifically in La Crosse, WA. I chose this location because I have heard numerous times of how amazing the falls are and I felt this would be a great opportunity to finally see the 198 feet high falls. Palouse Falls interestingly enough doesn't reside in Palouse County; its closest recognizable city is La Crosse or the smaller town of Washtucna, which are in Franklin County. The towns run right along Highway 26. However even when in these towns you still face a little drive either down Ward street Or get onto 261 to get to Palouse falls state park.

What Is Summer Institute for the Gifted Should You Join

What Is Summer Institute for the Gifted Should You Join SAT / ACT Prep Online Guides and Tips Want to challenge yourself this summer? Interested in showing colleges some of your academic interests? If so, you might heave heard about the Summer Institute for the Gifted. In this post, we'll explain what the Summer Institute for the Gifted is all about; cover logistics such as application materials, cost, and dates; and help you decide whether it's a good fit for you. Feature image:Alfred Hutter/Wikimedia What Is Summer Institute for the Gifted? The Summer Institute for the Gifted (SIG) is an academic summer program for the â€Å"gifted and talented† aged 5-17. "Gifted and talented" basically means that you have been placed in a gifted program in school or that you have tested above the 95th percentile on a nationally normed test (we'll go over the eligibilityinfo in more detail below). You don't have to take a special test or submit an elaborate application to be considered. The program consists of three-week sessions held on various campuses around the country. Some camps are residential (meaning you live on-campus for the entire session) but also allow for commuter students, whereas others are exclusively day programs. Each program has its own dates. The earliest programs begin in late June and run through mid-July, while the latest programs run from late July to mid-August. (See specific dates for the residential programs and day programson SIG’s website.) If you're in a residential camp, you take a series of courses during weekdays and participate in recreation during evenings and weekends. What Are SIG Classes Like? Your classes will be a mix of academic (in subjects from the humanities, science, and math) and recreational. Courses vary by location and are mostly separated by age level. So you might be in some academic classes with only students of your grade but in recreation classes with students of various ages. You sign up for your classes before you get there, but you can change your courses in the first two days. This gives you a chance to get a feel for different classes and hopefully come up with a schedule that’s a good balance for you. Schedule and Residential Life at SIG You take your classes during the day from 8:45 am to 4:15 pm with a lunch break, followed by a recreation period, dinner, and a study tutorial in the evenings. So in some ways it’s kind of like your schedule during the school year, but a bit more intense since you’re living with other students and taking more challenging classes. On the weekends, there are local excursions, planned activities, and free time. You live in a residence hall with students of your same age and gender, and also have a roommate (it’s possible to request a single room, but it’s a bit more expensive). While the layout and size will vary, you can expect your typical dorm room to have a bed, dresser, desk, and, of course, a roommate! The day programs consist of the academic portion of the program, but you don’t stay in a residence hall or have weekend activities. The day program could be a good option if you want the academic experience but have other extracurricular or social commitments over the summer. Locations for Summer Institute for the Gifted SIG has a variety of locations all across the country. The residential programs are housed at universities, and the day programs are housed at a mix of universities and local schools. See below for a complete list. Residential Program Bryn Mawr College (Pennsylvania) Emory University (Georgia) Northeastern University (Massachusetts) Princeton University (New Jersey)* University of California, Berkeley University of California, Los Angeles University of Chicago (Illinois) University of Miami (Florida) Yale University (Connecticut) *Does not allow for commuter students. Day Program Boston University (Massachusetts) Bryn Mawr College (Pennsylvania) California Lutheran University Chatham Day School (New Jersey) Echo Horizon School (California) Emory University (Georgia) Fairfield University (Connecticut) The Overlake School (Washington) Sarah Lawrence College (New York) Stuart Country Day School (New Jersey) University of Miami (Florida) The Woods Academy (Maryland) The Wesley School (California) How to Get Into SIG You can apply online or by mail for SIG. To apply, you'll need topay a $99 application fee and send in an application form. The application form is pretty straightforward - you give your personal and demographic info, say which program you want to attend, and list your course preferences. Finally, if it’s your first year, you must also submit eligibility info. You have to meet at least one of the following criteria: Score at the 95th percentile or higher in one of the major content areas of a nationally normed standardized test administered by your school (this includes a lot of state testing or the SAT/ACT). See a full list of tests here. Participate in an academic talent search. Be identified as gifted orparticipate in a local or school gifted program. Score at least two standard deviations above the mean, or at the 95th percentile level or higher, on any individual or group-administered, nationally normed standardized intelligence assessment. If none of the above are available for you (your district doesn't have a gifted program, you haven't taken any of the standardized tests listed by SIG, and there are no talent searches you can participate in), you can have two teachers at your school fill out letters of recommendation for you instead. You should apply early in the year as programs, especially the ones at Princeton and Yale, tend to fill up before summer.Admissions are rolling,so you need to apply to popular programs as early as possible. Less popular locations might still have open spaces through June. If you're interested in attending SIG in future years, try to apply as early as possible to maximize your chances of getting your first-choice location. Cost of SIG SIG costs between $3,000 and $5,800, depending on the location, for the three-week residential option. The day programs are cheaper: between $1,200 and $4,500. A chart of costs for the residential SIG camps, via the SIG Application Form. You can apply for financial assistance using this form. Try to apply early if you anticipate needing financial assistance, as funds for these types of programs tend to run out closer to the start dates. Is SIG Worth It? You can definitely get a challenging academic summer experience by doing SIG. Many former participants say good things about the experience on online forums and blogs. In particular, many participants say it can be rewarding for students to meet other academically gifted students and make friends from different parts of the country. That said, your time is very scheduled and the program is expensive, so you might want to consider other opportunities closer to home if you want more flexibility. You certainly won’t be penalized in the college admissions process for not doing a program like SIG. Especially if you live in a district where you have access to challenging classes or a gifted program, the benefits might not be that substantial. Other great summer options include participating in local music competitions, volunteering, doing research, or taking classes at local community colleges or universities. Explore both local options and programs like SIG before deciding what's right for you. The main goal is to use your time over the summer to dig deeper into an academic or extracurricular interest. SIG is one way to do that, but make sure you consider other possible options to get the most out of your summer! What’s Next? Curious about other summer programs?

Discussion Paper on Utilitarian Theory and Duty Oriented Theory Essay

Discussion Paper on Utilitarian Theory and Duty Oriented Theory - Essay Example This rule is applied directly to a selection of particular actions under particular events (Mill). This implies that there are no fixed principles that can be established before the occurrence of any specific event, and that the particular action that works for the greater benefit of society should be the preferred method. Hence the judgment on what constitutes the ‘greater good’ is of extreme importance when following act utilitarianism. There can be counter arguments to the aforementioned notion because, while the majority’s verdict may satisfy everyone in the short run, it may have negative implications for everyone in the long run. This raises concerns over the guaranteed presence of someone shrewd enough to judge what constitutes the greater good of the society. Rule Utilitarianism:- Rule utilitarianism states that it is our duty to abide by rules designed for the greater total good and produce consequences better than those produced by any other rules. This doctrine is applied to a selection of a set of rules which are then used to determine what to do in particular situations. The primary argument of rule utilitarianism is that there should be pre established rules that define what constitutes the greater good. ... Duty Oriented Theories: Duty oriented theories fall under the category of nonconsequentalists theories. Nonconsequentalists believe that there can be rules to guide moral judgments independent of consequences. The underlying argument of these theories is that the means justify the ends rather than the other way round and if the moral conduct undertaken to achieve an acceptable consequence is incorrect than the entire act is incorrect. There are several theories that follow this school of thought. The divine command theory suggests that moral conduct is judged on the basis of the level of fulfillment of rules laid down by a higher authority. This is an extreme end of the nonconsequentalists theories that seeks to abandon control completely. Emanuel Kant was one of the key contributors to duty oriented ethics. Kant’s theory stems from his arguments about misconceptions about the purpose of life and what makes one happy. He argues that if the purpose of life was to achieve happin ess, we shall all seek gratification and pleasure and believe that it shall lead to happiness. But happiness is not within out power to achieve, and is at times, a matter of luck. He also suggests that if we are to avoid skepticism, our ethics should be rational, unconditional and universal. Kant believes that it is not important that the consequences be of our choice, but the thinking behind our choices. He argues that the only one kind of thing that is inherently good is good will. Kant proposed a categorical imperative that shall guide our moral behavior. The categorical imperative argues that One should act on only those maxims (rules of action)

HRD Essay Example | Topics and Well Written Essays - 250 words

HRD - Essay Example Different strategies are widely used by organizations to help individuals realize their full potential for working so that it will foster the individuality and yet enhance the effectiveness within particular contexts. Swanson and Holton (p. 4) defined HRD as an HRM strategy that focuses on developing and unleashing knowledge, skill and expertise for the purpose of improving individual, team, work process and organizational system performance. According to this definition, HRD is an approach to create and foster high performance working in an organization. International Labour Organisation (p. 1) emphasized that HRD involves issues such as education, training, recruitment, staffing, performance and career development etc. All the different development programs can improve work-standard of the people in an organization, and as a result, the organization would be able to achieve high performance working, as pointed out in the definition of Swanson and Holton. What makes human capital the more powerful assets in the organization? It is the knowledge they have, the skill they are born with, the abilities expertise they earned and so on. Physical development of the human resources in an organization is not as significant as developing their knowledge, skill and expertise. Organizations need to improve these qualities of human capital as these can increase the productivity, work standard and thus to achieve high performance working as well. As Reid, Barrington and Brown (p. 12- 14) education, training, skill-development are some of the main elements in the HRD that are meant to improve the quality human resources. It is simply a strategic approach to effectively utilizing the

Fastest Finger First Project Report

Fastest Finger First Project Report Abstract In the buzzer round of quiz contests, the question is thrown open to all the teams. The person who knows the answer hits the buzzer first and then answers the question. Sometimes two or more players hit the buzzer almost simultaneously and it is very difficult to detect which of them has pressed the buzzer first. In television shows, where the whole event is recorded, the actions are replayed in slow motion to detect the first hit. Such slow motions are possible only where huge funds are available to conduct the show. For this reason buzzer rounds are avoided for quiz contests held in colleges. This project is an electronic quiz buzzer that is affordable by the colleges and even individuals. This project is useful for a 4-team quiz contest, although it can be modified for more number of teams. This system is sensitive. The circuit can detect and record the first hit contestant among all the contestants that may appear to be simultaneous Buzzer controllers for 4-team quizzes are readily available in the market. However, buzzer controller capable handling six or eight team are hard to find. The circuit presented here can be used for up to eight teams. It can be easily expanded to accommodated more teams through suitable cascading of latches and AND gates along with transistors, relays, etc. In the buzzer round of any quiz contest question are thrown open to all the participating teams. Each team has a push button switch to ring the buzzer. After hearing the question any member of a team who knows the answer and hits there switch first gets a chance to answer. In multiple cases who hit the switch first gets the opportunity to reply. For next round the quiz master reset the buzzer operation circuit by pressing the reset switch. For visual indication all teams have the lamp fitted on their desk. The lamps glow until the reset of buzzer controller indicating the eligible team for replying the question. For audio indication the buzzer rings and turns off automatically after a few second. The audio visual circuit is powered through actuation of relay contacts. Here 230v AC has been used. BLOCK DIAGRAM Figure:1 CIRCUIT DIAGRAM Figure:2 Figure:2 Working of Finger first indicator Fastest finger first indicators (FFFIs) are used to test the players reaction time. The players designated number is displayed with an audio alarm when the player presses his entry button. The circuit presented here determines as to which of the 8 contestants first pressed the button and locks out the remaining three entries. Simultaneously, an audio alarm and the correct decimal number display of the corresponding contestant are activated. When a contestant presses his switch, the corresponding output of latch IC1 (74373) changes its logic state from 1 to 0. The combinational circuitry comprising dual 4-input NAND gates of IC3 (7430) locks out subsequent entries by producing the appropriate latch-disable signal. Priority encoder IC2 (74147) encodes the active-low input condition into the corresponding binary coded decimal (BCD) number output. The outputs of IC4 after inversion by inverter gates inside hex inverter 74LS04 (IC5) are coupled to BCDto-7-segment decoder/display driver IC6 (7447). The output of IC6 drives common anode 7-segment LED display (DIS.1, FND507 or LT543). The audio alarm generator comprises clock oscillator (555), whose output drives a loudspeaker. The oscillator frequency can be varied with the help of Preset VR1. Logic 0 state at one of the outputs of IC2 produces logic 1 input condition at pin 4 of 555, thereby enabling the audio oscillator. 555 needs +12V DC supply for sufficient alarm level. The remaining circuit operates on regulated +5V DC supply, which is obtained using (7805).Once the organiser identifies the contestant who pressed the switch first, he disables the audio alarm and at the same time forces the digital display to 0 by pressing reset pushbutton S9 PCB FABRICATION PCB Designing is an important part of the project development, complexity size the PCB for our Project Buzzer Controller For 8-Team Quiz Contests is made by Photo chemical process on copper clad base materials the following steps are involved in Fabrication.

IC7447 Figure:20 8 .Transformer Figure:21 Laminated steel core Transformers for use at power or audio frequencies typically have cores made of high Permeability (electromagnetism) permeabilitysilicon steel. permeability many times that of free space, and the core thus serves to greatly reduce the magnetizing current, and confine the flux to a path which closely couples the windings. Early transformer developers soon realized that cores constructed from solid iron resulted in prohibitive eddy-current losses, and their designs mitigated this effect with cores consisting of bundles of insulated iron wires. Later designs constructed the core by stacking layers of thin steel laminations, a principle that has remained in use. Each lamination is insulated from its neighbors by a thin non-conducting layer of insulation.indicates a minimum cross-sectional area for the core to avoid saturation. The effect of laminations is to confine eddy currents to highly elliptical paths that enclose little flux, and so reduce their magnitude. Thinner laminations reduce losses, Thin laminations are generally used on high frequency transformers, with some types of very thin steel laminations able to operate up to 10  kHz. One common design of laminated core is made from interleaved stacks of pieces, leading to its name of E-I transformer.Such a design tends to exhibit more losses, but is very economical to manufacture. The cut-core or C-core type is made by winding a steel strip around a rectangular form and then bonding the layers together. It is then cut in two, forming two C shapes, and the core assembled by binding the two C halves together with a steel strap. They have the advantage that the flux is always oriented parallel to the metal grains, reducing reluctance. A steel cores means that it retains a static magnetic field when power is removed. When power is then reapplied, the residual field will cause a high until the effect of the remaining magnetism is reduced, usually after a few cycles of the applied alternating current. Over current protection devices such as must be selected to allow this harmless inrush to pass. On transformers connected to long, overhead power transmission lines, induced currents due to during can cause saturation of the core and operation of transformer protection devices. The transformer converts the 220 V AC into 9 V AC. The Bridge wave rectifier converts the ( V AC into rippled DC. This rippled DC is given as input to the 7805/7809 Voltage regulator IC. A separate power supply is given for the Stepper Motor which has the same power supply setup for converting the 220 V AC into 9V DC. The DC Power Supply circuit is based around the 7805 voltage regulator. It has only 3 connections (input, output and ground) and it provides a fixed output. The last two digits of the part number specify the output voltage, eg. 05, 06, 08, 10, 12, 15, 18, or 24. The 7800 series provides up to 1 amp load current and has on-chip circuitry to shut down the regulator if any attempt is made to operate it outside its safe operating area. (If this happens to you, let the chip cool down attach the heatsink.) It can be seen that there are in fact two separate circuits in this power supply. One 7805 is directly connected as a fixed 5V regulator. The second 7805 has a resistor divider network on the output. A variable 500 ohm potentiometer is used to vary the output voltage from a minimum of 5V up to the maximum DC voltage depending on the input voltage. It will be about 2V below the input DC voltage.) The capacitor across the output improves transient response. The large capacitor across the input is a filter capacitor to help smooth out ripple in the rectified AC voltage. The larger the filter capacitor the lower the ripple IC-7805 One can get a constant high-voltage power supply using inexpensive 3-terminal voltage regulators through some simple techniques described below. Depending upon the current requirement, a reasonable load regulation can be achieved. Line regulation in all cases is equal to that of the voltage regulator used. Though high voltage can be obtained with suitable voltage boost circuitry using ICs like LM 723, some advantages of the circuits presented below are: simplicity, low cost, and practically reasonable regulation characteristics. For currents of the order of 1A or less, only one zener and some resistors and capacitors are needed. For higher currents, one pass transistor such as ECP055 is needed. Before developing the final circuits, let us first understand the 3-terminal type constant voltage regulators. Let us see the schematic in Fig. where 78XX is a 3-terminal voltage regulator. Schematic for obtaining low-voltage regulated output using 3-terminal Figure:22 voltage regulators. Rectified and filtered unregulated voltage is applied at VIN and a constant voltage appears between pins 2 and 2 of the voltage regulator. *The distribution of two currents in the circuit (IBIAS and ILOAD) is as shown. It is highly recommended to use the two capacitors as shown. Electrically regulator will be at a distance from the rectifier supply. Thus, a tantalum grade capacitor of 5mf and rated voltage is good. Electrolytic capacitor is not suitable for it is poor in response to load transients, which have high frequency components.At the output side a 0.22mf disc ceramic capacitor is useful to eliminate spurious oscillations, which the regulator might break into because of its internal high gain circuitry. Figure:23 These voltage regulators have a typical bias current of 5 mA, which is reasonably constant. By inserting a small resistor Rx between pin 2 and ground, the output voltage in many cases. By this method voltage increment of 5 to 10 per cent is practically feasible. However, if a high-value resistance is used to obtain a higher output voltage, a slight variation in bias current will result in wide variation of the output voltage. 8. BC547 Transistor In electronics, a transistor is a semiconductor device commonly used to amplify or switch electronic signals. A transistor is made of a solid piece of a semiconductor material, with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistors terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be much larger than the controlling (input) power, the transistor provides amplification of a signal. The transistor is the fundamental building block of modern electronic devices, and is used in radio, telephone, computer and other electronic systems. Some transistors are packaged individually but most are found in integrated circuits. Figure:24 Features à ¢Ã¢â€š ¬Ã‚ ¢ NPN Silicon Epitaxial Planar Transistors à ¢Ã¢â€š ¬Ã‚ ¢ These transistors are subdivided into three groups A, B, and C according to their current gain.

Compact Size Non Inductive Design 11.RESISTANCE Resistance is the opposition of a material to the current. It is measured in Ohms ( -). All conductors represent a certain amount of resistance, since no conductor is 100% efficient. To control the electron flow (current) in a predictable manner, we use resistors. Electronic circuits use calibrated lumped resistance to control the flow of current. Broadly speaking, resistor can be divided into two groups viz. fixed adjustable (variable) resistors. In fixed resistors, the value is fixed cannot be varied. In variable resistors, the resistance value can be varied by an adjusteknob. It can be divided into (a) Carbon composition (b) Wire wound (c) Special type. The most common type of resistors used in our projects is carbon type. The resistance value is normally indicated by colour bands. Each resistance has four colours, one of the band on either side will be gold or silver, this is called fourth band and indicates the tolerance, others three band will give the value of resistance (see table). For example if a resistor has the following marking on it say red, violet, gold. Comparing these coloured rings with the colour code, its value is 27000 ohms or 27 kilo ohms and its tolerance is  ±5%. Resistor comes in various sizes (Power rating). The bigger, the size, the more power rating of 1/4 watts. The four colour rings on its body tells us the value of resistor value as given below. COLOURS CODE Black 0 Brown 1 Red 2 Orange 3 Yellow 4 Green 5 Blue 6 Violet 7 Grey 8 White 9 Figure:29 The first rings give the first digit. The second ring gives the second digit. The third ring indicates the number of zeroes to be placed after the digits. The fourth ring gives tolerance (gold  ±5%, silver  ± 10%, No colour  ± 20%). In variable resistors, we have the dial type of resistance boxes. There is a knob with a metal pointer. This presses over brass pieces placed along a circle with some space b/w each of them. Resistance coils of different values are connected b/w the gaps. When the knob is rotated, the pointer also moves over the brass pieces. If a gap is skipped over, its resistance is included in the circuit. If two gaps are skipped over, the resistances of both together are included in the circuit and so on. 12.The 555 TIMER Description The LM555/NE555/SA555 is a highly stable controller capable of producing accurate timing pulses. With a monostable operation, the time delay is controlled by one external resistor and one capacitor. With an astable operation, the frequency and duty cycle are accurately controlled by two external resistors and one capacitor.

This can be any voltage between 3V and 15V DC, but is commonly 5V DC when working with digital ICs. Pin 1 is the 0V connection to the power supply. Trigger and Reset Inputs: Pin 2 is called the trigger input as it is this input that sets the output to the high state. Pin 4 is called the reset input as it is this input that resets the o/p to the low state. Both pins may be connected to push buttons to control the operation of the 555.Sometimes the reset input is not used in a circuit, in which case it is connected directly to Vs to that unwanted resetting cant occur. Threshold and discharge: Pins 6 and7 (and sometimes the Trigger i/p, pin2) are used to set up the timing aspect of the 555 IC. They are normally connected to a combination of resistors and a capacitor. Offset: Pin 5 can be used to alter the timing aspect of the 555 IC in applications such as frequency modulation. Output: Pin 3 is the digital output of the 555.It can be connected directly to the inputs of other digitaICs, or it can control other devices Figure:32 When the low signal input is applied to the reset terminal, the timer output remains low regardless of the threshold voltage or the trigger voltage. Only when the high signal is applied to the reset terminal, the timers output changes according to threshold voltage and trigger voltage. When the threshold voltage exceeds 2/3 of the supply voltage while the timer output is high, the timers internal discharge Tr. turns on, lowering the threshold voltage to below 1/3 of the supply voltage. During this time, the timer output is maintained low. Later, if a low signal is applied to the trigger voltage so that it becomes 1/3 of the supply voltage, the timers internal discharge Tr. turns off, increasing the threshold voltage and driving the timer output again at high. Fig 33 :Monostable Operation Figure:34 Figure 34. illustrates a monostable circuit. In this mode, the timer generates a fixed pulse whenever the trigger voltage falls below Vcc/3. When the trigger pulse voltage applied to the #2 pin falls below Vcc/3 while the timer output is low, the timers internal flip-flop turns the discharging Tr. off and causes the timer output to become high by charging the external capacitor C1 and setting the flip-flop output at the same time. The voltage across the external capacitor C1, VC1 increases exponentially with the time constant t=RA*C and reaches 2Vcc/3 at td=1.1RA*C. Hence, capacitor C1 is charged through resistor RA. The greater the time constant RAC, the longer it takes for the VC1 to reach 2Vcc/3. In other words, the time constant RAC controls the output pulse width. When the applied voltage to the capacitor C1 reaches 2Vcc/3, the comparator on the trigger terminal resets the flip-flop, turning the discharging Tr. on. At this time, C1 begins to discharge and the timer output conver ts to low. In this way, the timer operating in the monostablerepeats the above process. Figure 10 shows the general waveforms during the monostable operation. It must be noted that, for a normal operation, the trigger pulse voltage needs to maintain a minimum of Vcc/3 before the timer output turns low. That is, although the output remains unaffected even if a different trigger pulse is applied while the output is high, it may be affected and the waveform does not operate properly if the trigger pulse voltage at the end of the output pulse remains at below Vcc/3 Fig 35 :Astable operation An astable timer operation is achieved by adding resistor RB to Figure 1 and configuring as shown on Figure 5. In the astable operation, the trigger terminal and the threshold terminal are connected so that a self-trigger is formed, operating as a multi vibrator. When the timer output is high, its internal discharging Tr. turns off and the VC1 increases by exponential function with the time constant (RA+RB)*C. When the VC1, or the threshold voltage, reaches 2Vcc/3, the comparator output on the trigger terminal becomes high, resetting the F/F and causing the timer output to become low. This in turn turns on the discharging Tr. and the C1 discharges through the discharging channel formed by RB and the discharging Tr. When the VC1 falls below Vcc/3, the comparator output on the trigger terminal becomes high and the timer output becomes high again. The discharging Tr. turns off and the VC1 rises again. In the above process, the section where the timer output is high is the time it takes for the VC1 to rise from Vcc/3 to 2Vcc/3, and the section where the timer output is low is the time it takes for the VC1 to drop from 2Vcc/3 to Vcc/3. When timer output is high, the equivalent circuit for charging capacitor C1 is as follows Fig 36 :Astable operation Waveform 12.Diode The simplest semiconductor device is made up of a sandwich of P-type semiconducting material, with contacts provided to connect the p-and n-type layers to an external circuit. This is a junction Diode. If the positive terminal of the battery is connected to the p-type material (cathode) and the negative terminal to the N-type material (Anode), a large current will flow. This is called forward current or forward biased. If the connections are reversed, a very little current will flow. This is because under this condition, the p-type material will accept the electrons from the negative terminal of the battery and the N-type material will give up its free electrons to the battery, resulting in the state of electrical equilibrium since the N-type material has no more electrons. Thus there will be a small current to flow and the diode is called Reverse biased. Thus the Diode allows direct current to pass only in one direction while blocking it in the other direction. Power diodes are used in concerting AC into DC. In this, current will flow freely during the first half cycle (forward biased) and practically not at all during the other half cycle (reverse biased). This makes the diode an effective rectifier, which convert ac into pulsating dc. Signal diodes are used in radio circuits for detection. Zener diodes are used in the circuit to control the voltage. Figure:37 Some common diodes are:- 1. Zener diode. 2. Photo diode. 3. Light Emitting diode. ZENER DIODE:- A zener diode is specially designed junction diode, which can operate continuously without being damaged in the region of reverse break down voltage. One of the most important applications of zener diode is the design of constant voltage power supply. The zener diode is joined in reverse bias to d.c. through a resistance R of suitable value. PHOTO DIODE:- A photo diode is a junction diode made from photo- sensitive semiconductor or material. In such a diode, there is a provision to allow the light of suitable frequency to fall on the p-n junction. It is reverse biased, but the voltage applied is less than the break down voltage. As the intensity of incident light is increased, current goes on increasing till it becomes maximum. The maximum current is called saturation current. LIGHT EMITTING DIODE (LED):- When a junction diode is forward biased, energy is released at the junction diode is forward biased, energy is released at the junction due to recombination of electrons and holes. In case of silicon and germanium diodes, the energy released is in infrared region. In the junction diode made of gallium arsenate or indium phosphide, the energy is released in visible region. Such a junction diode is called a light emitting diode or LED.

Franz Kafka Essay

Franz Kafka was born in Prague on July 3rd 1883, a German-speaking Jew. His father was a large, dominating man named Hermann. A lot of his work reflected his hatred for his father, in the play Metamorphosis and also in Letter to His Father, which reflects his feelings of inferiority and paternal rejection. His work was not of one specific genre. His work was of fantasies, dreams and human suffering. It was eclectic. Dying of Tuberculosis after the First World War, he wanted his work to be burnt upon his death, but his friend, Max Brod realised their potential and published them contrary to his wishes. His three most renowned pieces of work were The Trial, The Castle and Amerika. Kafka’s three sisters all perished in German concentration camps. The themes of Kafka’s work are the loneliness, frustration, and oppressive guilt of an individual threatened by anonymous forces beyond his comprehension or control. In literary technique, his work has the qualities both of expressionism and of surrealism. Kafka’s lucid style, blending reality with fantasy and tinged with ironic humour, contributes to the nightmarish, claustrophobic effect of his work. Like in his famous long short story â€Å"Metamorphosis† where Gregor Samsa, a hardworking insurance agent, awakens to find that he has turned into an enormous insect. Rejected by his family, he is left to die alone. Simulating the situation in his own home, it seems that Kafka based Gregor around himself. Mr. Samsa also seems to be represented as Hermann Kafka, Franz’s own dominating father. Kafka was heavily influenced by religion. As a Jew in his time, there were huge effects of anti-Semitism on their race, although Hitler’s rule over Germany and his terror-regime over the Jewish at the time was later on in the 1930’s, Kafka probably would have faced racist remarks and cruelty towards him and his work. As the son of an assimilated Jew who held only perfunctorily to the religious practices and social formalities of the Jewish community, Kafka was German both in language and culture. The absurdity of this social and cultural position created an ambiguous reality for Kafka, often more hallucinatory than realistic. Steven Berkoff was born into a family of Russian Jewish immigrants, and was born in the East End of London on the 3rd August 1937. During World War 2, in 1942 he was evacuated to Luton to avoid bombing. When he was 14 years old his family moved to the USA. This gave him the vision to see where he wanted to go and what he wanted to do in life. Moving back to Britain, he finished school, saved up enough money and went to France at the age of 19 to study the art of mime. Upon returning to London in 1968 he formed the London Theatre Group. It was in 1969 that Berkoff remade Kafka’s Metamorphosis. In 1976 he married his second (and present) wife, Shelley Lee. With the London Theatre Group, Berkoff attempted to create something unique. The London Theatre Group prided itself with trying to cover all forms of theatre. They wanted to be everything. They called their work a â€Å"fusion of elements†. Their main aim was to shock the audience. There were no set rules to Berkoff’s theatre. It was a mixture of many kinds of theatre, influenced by many people. The London Theatre Group wanted people of all social backgrounds to come and see their plays. Another thing they tried to do was to move away from conventional theatre, and use different ways of using the stage and positioning the audience. In The Penal Colony, The Trial and Metamorphosis were three plays of Kafka’s that Berkoff remade. Other plays the London Theatre Group has performed include Macbeth, Miss Julie versus Expressionism, Agamemnon, The Fall of the House of Usher, East, Greek, Hamlet, Decadence, West, Lunch, Actor, Harry’s Christmas, Kvetch, Sink the Belgrano!, Salome, Acapulco, Brighton Beach Scumbags, Dog, Storm und Drang, Dahling you were Marvellous, Massage, Shakespeare’s Villains, The Messiah. The Bow of Ulysses, Ritual in Blood and The Secret Love Life of Ophelia amongst many others. He also starred in many movies such as A Clockwork Orange and Rambo. He usually played the villain, but the main reason for his film roles was to fund his theatre productions. Berkoff was an atheist, explaining his wish to attract people of all social masses to see his plays. He never uses religious effects in his plays to avoid any conflict of cultures. Brecht was an influence of Berkoff. Brecht didn’t want to get involved with an audience. Another influence was Peter Brook, an expert of slapstick. Stanislavski believed in naturalism, the opposite of Brecht, and yet Berkoff used elements from both Brecht and Stanislavski in his work. This is shown in Metamorphosis, as without the audience’s sympathies for Gregor, the play would not work. Antonin Artauds was another influence. He was involved in theatre of the absurd. Again, Berkoff uses these ideas, mainly to shock the audience in his productions.

Article Summary The Age of Educational Romanticism

Article Summary: The Age of Educational Romanticism Charles Murray discusses the nature of The Age of Educational Romanticism in this 2008 article from The New Criterion. The author defines this age as the belief that all children who are not doing well in school have the potential to do much better. Murray characterizes educational romantics as people who believe that the academic achievement of children is determined mainly by the opportunities they receive and has little to do with their intellectual capacity. Educational romantics believe the current K-12 education system is in need of vast improvement. Murray describes two types of educational romantics, one set on the Left and one on the Right, and differentiates between the two thusly: Educational romantics of the Left focus on race, class, and gender. It is children of poor parents, and girls whose performance is artificially depressed, and their academic achievement will blossom as soon as they are liberated from the racism, classism, and sexism embedded in American education. Those of the Right see public education as an ineffectual monopoly, and think that educational achievement will blossom when school choice liberates children from politically correct curricula and obdurate teachers unions (Murray). Both of these accounts fail to take into account the vast differences in intellectual ability that permeates the average American classroom.
