Essay on Dream Deferred in Song of Solomon -- Song Solomon essays

The American Dream Deferred in Song of Solomon   â Beginning with the principal African American scholarly works through the later victories, for example, Toni Morrison's Song of Solomon the subject of education is inseparably associated with opportunity and force. A closer examination, in any case, drives the peruser to another, less immediate, message demonstrating that maybe this confidence in education as a pathway to the American Dream of opportunity and social and money related achievement is opposing or, in any event, deficient in social and social terms. Along these lines, African American writing remakes the American Dream into a considerably progressively complex dream conceded.  Toni Morrison deconstructs the American Dream and the proficiency fantasy in The Song of Solomon by criticizing formal training and education while stressing oral family ancestry. A most obtrusive scorn of formal instruction goes to the peruser in the narrative of First Corinthians Dead, the main character in the novel to go to school. First Corinthians finds that instruction made her excessively rich (188), and that Bryn Mawr had done what a four-year portion of liberal training was intended to do: unfit her for 80% of the helpful work of the world, (189). At forty-two, First Corinthians is undeveloped, unmarried and unfulfilled, because of her advanced degree.  Milkman, then again, isn't sent to school and is at last instructed by the oral family ancestry uncovered by Pilate and the townspeople of Shalimar, Virginia. Milkman's opportunity comes simply after he breaks the chains of the American Dream legend his dad is slave to and searches out his history, his way of life, and his personality.  Milkman's dad, Macon Dead II, is sure that... ...eedom, autonomy and balance based on the effective exchange of ignorance, yet of a past filled with social and social disavowal. Such is the idea of the fantasy conceded.  WORKS CITED Blossom, Harold, ed. Current Critical Views: Toni Morrison. New York: Chelsea House Publishing, 1990. Graff, Harvey J.

Why Grammar Is Important

Clearly very few individuals acknowledge how significant syntax is. There are such a significant number of contractions thus much slang these days, it is difficult to recognize what individuals mean. I can’t even check how often I have needed to call somebody to ask them what they were discussing in an instant message since they didn’t utilize right accentuation and punctuation. I never paid consideration that a lot to language structure or accentuation either when I was in rudimentary and center school. In any case, since the time I have gotten to secondary school, I have become a syntax Nazi.Which carries me to this end, youngsters are being taught enough to be employed for work, they simply decide not to focus in class. Presently I realize that my decision sounds awful, so let me expand. Occupations ought not be so basic on who they decide to enlist; particularly when it is something as trivial as getting â€Å"to† and â€Å"too† stirred up. It relies u pon the activity however what sort of English training they ought to have. In the event that work doesn't require a lot of composing, why does it matter? Except if you are utilizing things like â€Å"YOLO† or â€Å"LOL† on your resume, at that point there is no problem.If work requires great English, at that point truly, I can see the issue. I should concede, in any case, that I have heard a few servers and clerks utilize some odd syntax. It makes you mull over the stuff to find a new line of work in today’s time. I comprehend that homophones can be confounding. Consider it, â€Å"here† and â€Å"hear†, â€Å"they’re†, â€Å"their†, and â€Å"there†. Is it just me, or do others understand that it isn't that difficult to understand the distinctions? As I stated, I have become a total language structure Nazi, I HATE seeing things like that. I went to there house and they’re hound bit me. † No, you went to thei r home and their pooch bit you. I swear, it seems as though individuals commit these bonehead errors intentionally. Something different that relatively few individuals know, language structure spares lives†¦ Moreover, faces. Take for example an announcement like this: â€Å"Lets it Grandma! † It ought to be, â€Å"Let’s eat, Grandma! † It is stunning how one basic comma can spare a dear old woman’s life. â€Å"Woman without her man is nothing. † Pardon me? Progressively like, â€Å"Woman: Without her, man is nothing. † That is better.Also, a touch of guidance for those attempting to sound amazing when they state, †I could mind less,† it’s, †I couldn’t care less. † By saying that you could mind less is suggesting that you do really mind. As should be obvious, language structure has a tremendous effect of our lives. It likewise is the premise of the contrast between what you need individuals to think you mean, and what they think you mean. So make life simple on everybody, utilize right syntax and spelling. Quit clubbing child seals. Or then again, quit clubbing, child seals. Keep in mind, sentence structure spares lives.

summer lovin ??

summer lovin ?? As of one week ago, it is officially summer!!!01 and oh boy does the weather know it... i swear it jumped like 5 degrees celsius as soon as the solstice came around Heres what Im up to :D In like November/December (which seems so long ago now), the concept of summer wasnt real to me. I couldnt visualize my actual self having a summer, only what The Ideal Nonexistent MIT Student would be doing in my place. So I applied to some fancy-dancy computer science internships and got some much-less-fancy rejection emails. (Which wasnt too surprising, given my relative lack of related experience.) This did not particularly get me down, however, because over the winter break I realized that it was my actual self, and not the Ideal MIT Student, who would be existing this summer. And my actual self really wanted to go home for the summer. Like, REALLY wanted to go home. I missed my parents, my house, my city, my dog, my friends So I googled for the email addresses of some professors at the university near home, sent out cold emails aka begged strangers for a job, and three Skype interviews later, here I am! It turns out that me and my very weird and variegated resume (programming, Latin, linguistics) are just right for a very particular project: looking at DEEDS, or the *clears throat* Documents of Early England Data Set. Heres a real contract! The picture is from the French book Les Pratiques de LÉcrit Dans Les Abbayes Cisterciennes, and the caption in French is describing the subject of the contract (some land being given to monks from Pontigny). The background is that in medieval England, every time a contract was drawn up for land or property transfer, it was monks who did the writing (since, uh, writing is hard if you are a peasant). They wrote in Latin, of course, on vellum.02 aka pieces of animal skin Over time, the vellum fell apart, and all the little pieces of it were hard to keep track of. The contracts were recopied into big paper books, or cartularies, full of lots of different contracts, about different people and places and things. So although we still have the Latin words themselves, a lot of the original info about the contracts (say, when they were written, where, or by whom) has been lost. Enter: natural language processing! My job is to work together with some other people with different skillsets and backgrounds03 for example, statistics! i know no statistics, but hot diggity am i very rapidly figuring some out. to try to analyze the wording of the contracts and draw some useful conclusions. Did different orders of monks each have some words or phrases that were particular to them? What does that tell us about those orders (perhaps geographical location, or something about their values or faith)? Maybe right now youre thinking wow, that sounds really boring (like one of my friends said after I told him about my summer job you know who you are! ;) But I think its just the coolest thing ?? I get to write code, attempt and fail to translate medieval Latin,04 its actually pretty different from classical Latin in terms of vocabulary, and much less well documented -- if anyone knows of a good dictionary, plssss hit me up! and learn a bit of history too along the way. And you know what? Except for all the sitting,05 oh my god, so much sitting, im actually developing back problems having a job is pretty dang awesome. This is not a particularly Hot Take, but wow getting to go home at 5 pm and have the rest of the night to yourself, rather than having psets and essays and quiz prep follow you home, is incredible. I get to cook dinner with my parents! Or go out with my friends! My mom and I are lifting weights at the YMCA together, and I think Im going to start running with my dad.06 we run at the nearby high school track, and public school only just got out for the summer My city is such a beautiful place: filled with flowers and buildings and people. Time passes differently here, although just as weirdly: at MIT the days are slow because they are full, and the weeks are fast because I am tired. Here, the days are slow because they are empty (or, you know, emptier) and the weeks are fast because I am content. At MIT, Im happy Im always learning, moving forward, making progress, feeling satisfied but here, my forward pace has slowed.07 although not stopped -- i have learned SO MUCH about real-world programming in the past few weeks that my classes could never have taught me I am warmed by the sun, and like molasses, my time drips sloooooowly off the giant spoon of the universe. There is much more ahead of me: the fall, new classes, a new room, catching up with MIT friends but for now there is lunch in the sun with friends, a small dog who welcomes me home each night, cooking with my family and coding with a purpose, and life is very, very good.

FORTRAN History of a Programming Language

FORTRAN (or formula translation) was the first high-level programming language (software) invented by John Backus for IBM in 1954, released commercially in 1957. Fortran is still used today for programming scientific and mathematical applications. Fortran began as a digital code interpreter for the IBM 701 and was originally named Speedcoding. John Backus wanted a programming language that was closer in appearance to human language, which is the definition of a high-level language, other high language programs include Ada, Algol, BASIC, COBOL, C, C, LISP, Pascal, and Prolog. Generations of Codes The first generation of codes used to program the functions of a computer was called machine language or machine code. Machine code is the language a computer really understands on a machine level, being a sequence of 0s and 1s that the computers controls interpret as instructions electrically.The second generation of code was called assembly language. Assembly language turns the sequences of 0s and 1s into human words like add. Assembly language is always translated back into machine code by programs called assemblers.The third generation of code was called high-level language or HLL, which has human sounding words and syntax (like words in a sentence). In order for the computer to understand any HLL, a compiler translates the high-level language into either assembly language or machine code. All programming languages need to be eventually translated into machine code for a computer to use the instructions they contain. John Backus and IBM I really didnt know what the hell I wanted to do with my life... I said no, I couldnt. I looked sloppy and disheveled. But she insisted and so I did. I took a test and did OK. John Backus on his experience interviewing for IBM. John Backus headed the IBM team of researchers at the Watson Scientific Laboratory that invented Fortran. On the IBM team were the notable names of scientists like Sheldon F. Best, Harlan Herrick (who ran the first successful Fortran program), Peter Sheridan, Roy Nutt, Robert Nelson, Irving Ziller, Richard Goldberg, Lois Haibt, and David Sayre. The IBM team didnt invent HLL or the idea of compiling programming language into machine code, but Fortran was the first successful HLL and the Fortran I compiler holds the record for translating code for over 20 years. The first computer to run the first compiler was the IBM 704, which John Backus helped design. Fortran Today Fortran is now over forty years old and remains the top language in scientific and industrial programming—of course, it has constantly been updated. The invention of Fortran began a $24 million dollar computer software industry and began the development of other high-level programming languages. Fortran has been used for programming video games, air traffic control systems, payroll calculations, numerous scientific and military applications, and parallel computer research. John Backus won the 1993 National Academy of Engineerings Charles Stark Draper Prize, the highest national prize awarded in engineering, for the invention of Fortran.

Hero Honda Success Free Essays

‘Motorcycles are a hit in rural areas’ Monday, April 15, 2002 Many continue to be surprised at the ability of India ‘s 2-wheeler segment to buck the present recessionary trend in the economy. What, they ask themselves, accounts for such resilience: competitive pricing? Quality? Technology? Or, is it ready availability? Mr. Brijmohan Lall Munjal, chairman, Hero Group of Companies, addresses some of these issues in an interview with Soumya Kanti Mitra. We will write a custom essay sample on Hero Honda Success or any similar topic only for you Order Now What makes the 2-wheeler segment so impervious to demand fluctuations? A 2-wheeler is the most necessary consumer durable good owned by lower Middle, and middle class, households. There is multiple ownership of this product in such households. Firstly, there is an income effect that influences 2-wheeler demand. Per Capita GDP growth of 3. 7 per cent per annum has been pushing households up into higher income brackets. The push effect is more in lower and middle- income groups – hence the increased demand. It also links up with the higher contributions of the service sector to GDP; the income impact of that has been greater on lower income households. A second major reason is the inadequate public transport. The percentage of people who use public transport has fallen from 85 per cent to 75. Entry-level transport options like two- and three-wheelers have mostly filled this gap. They have also become a sort of necessity and thus do not show heavy fluctuations in demand. Increased demand for two-wheelers from households has also led financial institutions to increase credit in a sustained way in the last three or four years. That too has imparted stability to this item, compared to others. A good proportion of sales owes to replacement demand. Are motorcycles gaining an edge over scooters? What is your experience as a market leader? There are few fresh issues with scooters. Firstly, the technology was dated. Secondly, most were two-stroke vehicles, less fuel-efficient compared to motorcycles. The only advantage was that one could carry along a spare tyre. But motor- cycles have been preferred in rural areas for better ground clearance, larger wheels and better suspension. They can easily be used on rough roads. Scooters are preferred in urban segments. New generation vehicles with four-stroke engines may soon hit the market and that will boost the sagging scooter market. For the last two years scooters sales have been less than a million per annum. Are you, and others in the industry, planning changes in output and investment? Considering the developments in household incomes and transport requirements we believe that the average annual growth of 2-wheelers for the next three years should be of around 8-10 per cent. There is over-capacity, but investments may be made in individual instances. The demand for motorcycles, however, is expected to grow by 15-18 per cent. That should attract investments. Abroad, certain top-end models in BMW’s, Honda’s or Ducati’s ranges have actually become ‘lifestyle’ statements for executives. Do you see anything like that happening in India ? The next 2-3 years may see a small beginning with the introduction of high-end motorcycles. But the concept is too early for India . We do not have nice roads where the customer can ride such high-end bikes. With affordability not being widespread, who will manufacture to cater to such small volumes? We may see some inroads after imports get fully liberalised, but I think it is early days for that. Are exports from the sector under siege owing to the international slowdown? That could be a major factor. Also, there is over capacity in most countries in the 2- wheeler industry. Markets in Latin America and Africa are impacted, while intra- Asian trade is very competitive. How to cite Hero Honda Success, Papers

The Main Character in a Christmas Carol free essay sample

The main character in A Christmas Carol is named Ebenezer Scrooge. Scrooge is a stereotype of those who had power over those who didnt. Throughout the opening stave the character of Scrooge is established and it is quite clear what he is like. For example Dickens describes the character of Scrooge: No wind that blew was bitterer than he. This use of metaphors tells the reader a lot about the character Scrooge, and that he does not have a very good attitude or personality.This is shown especially because in the winter streets of London it is very cold and for Scrooge to be more bitter than the cold air just says that he is a mean and horrible person. Ebenezer Scrooge continues his stingy, greedy ways on Christmas Eve. He rejects a Christmas dinner invitation, and all the good tidings of the holiday, from his jolly nephew, Fred; he yells at charity workers; and he overworks his employee, Bob Cratchit. We will write a custom essay sample on The Main Character in a Christmas Carol or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page At night, Scrooges former business partner Jacob Marley, dead for seven years, visits him in the form of a ghost. Marleys spirit has been wandering since he died as punishment for being consumed with business and not with people while alive. He has come to warn Scrooge and perhaps save him from the same fate. He tells him Three Spirits will come to him over the next three nights: the Ghost of Christmas Past, the Ghost of Christmas Present, and the Ghost of Christmas Yet to Come.The first Spirit; The ghost of Christmas past, in my opinion, is extremely meaningful as it personifies memory. For example It was a strange figure like a child: yet not so like a child as like an old man. So the spirits description suggests to us that the character Scrooges childhood experiences can come back to him if he allows them to. Also the spirit is described here as: from the crown of its head there sprung a bright clear jet of light.Remembering that the ghost of Christmas past is the personification of memory this light symbolizes the illumination that comes from ones past and the cap the spirit wears symbolizes the ability everyone has to extinguish the light of memory, if he or she choose to do so, however at the end of stave two Scrooge tried to remove memories from the past but was unsuccessful: though Scrooge pressed it down with all his might, he could not hide the light: which screamed form under it. That quote also shows Dickens intelligent use of words because if you Screamed you are trying to escape.The other phrase Dickens used to describe the ghost of Christmas past is: Its hair which hung about its neck and down its back, was white as if with age;and The arms were very long and muscular; the hands the same. Both of these quotes compliment Dickens use of imagery as they give you a clear picture in your mind of what the spirits properties are. One other phrase in the story Dickens wrote was: It wore a tunic of the purest white; and round it waist was bound a lustrous belt, the sheen of which was beautiful. This says one thing, and that is that memory is pure, it cant be modified and its free from any influence to change. When the character, Scrooge meets the first spirit, the spirit starts to show Scrooge his past. Scrooge is taken to a country field and Scrooge himself recognizes the place as it was where he spent his childhood. Good heaven said Scrooge, clasping his hands together, as he looked about him. I was bred in this place. I was a boy here! There is an overwhelming flood of sensory connection with the place; this even brings a tremble to Scrooges lip and a tear to his cheek. This is evidence that in a moment, the past has become more alive to Scrooge than ever before.This shows already a big change in the character Scrooge has happened because this same character who could spare no time over his deceased business partner now tremble at the confronting memories of his youth. This evidence tell the reader that in a short time Scrooge has learnt lessons and that potentially as the story goes on Scrooge will learn more vital lessons. Of the many film versions of Charles Dickenss A Christmas Carol, the 1951 with Alastair Sim as Scrooge is the most faithful to the spirit of the book. It is, indeed, THE Christmas classic.This movie captures all the things that A Christmas Carol is supposed to be. Watching Alastair Sim interpret the role of Scrooge and then looking at other actors, I see his incredible facial expressions, the loss of soul that haunts him, the vulnerability, the loss of love from his once betrothed, and the terrible loneliness suffered at the hands of a vengeful father and the loss of his kind and loving sister, Fan. Scrooge is shown to be calculating at every point in time, but seems to know that in many ways he is wrong. His greed becomes his mistress and he cant forsake her. Greed seems to be a repetitive them in this story. The scene I remember most is how Scrooges greed drives away Belle, the young woman he loves. She cannot stay with him because he has made profit his main priority and she wont be second priority in his life. Scrooge really is so interested in his own profit that he doesnt make her stay with him because he realizes that she is right about his priorities. Because money is all that matters to him, money is all he is left with. Belle marries and has a family while Scrooge grows old, and rich, alone. However, there is as much greed as there is regret in this story. For example, when Scrooge learns that Tiny Tim will die if the future is unaltered, Scrooge is saddened. But when the Ghost of Christmas Present reminds him that when the collectors came to ask for a donation for the poor, Scrooge told them that those who were dying should go ahead and do it to decrease the population. Looking at Tiny Tim makes him realize that he was wrong to make such a statement and that those he might well consider an unnecessary surplus, could very well be those like Tim. The Ghost of Christmas Present once again uses Scrooges own words to make him regret his previous disrespect towards the poor.The ghost warns Scrooge that Want and Ignorance must be fought against or else the world is doomed and it is part of Scrooges duty to help fight against these social ills. Seeing these hideous monsters personified makes Scrooge realize how important it is to rid society of these self-created problems. Watching this movie is like reading the book and picturing it in your head. Charles Dicken’s message in A Christmas Carol is more relevant than it’s ever been. Mankind is our business and it’s important to practice kindness and compassion all of the days of the year and not just one.

Huygens Principle of Diffraction

Huygens Principle of Diffraction Huygens principle of wave analysis helps you understand the movements of waves around objects. The behavior of waves can sometimes be counterintuitive. Its easy to think about waves as if they just move in a straight line, but we have good evidence that this is often simply not true. For example, if someone shouts, the sound spreads out in all directions from that person. But if theyre in a kitchen with only one door and they shout, the wave heading toward the door into the dining room goes through that door, but the rest of the sound hits the wall. If the dining room is L-shaped, and someone is in a living room that is around a corner and through another door, they will still hear the shout. If the sound were moving in a straight line from the person who shouted, this would be impossible because thered be no way for the sound to move around the corner. This question was tackled by  Christiaan Huygens (1629-1695), a man who was also known for the creation of some of the  first mechanical clocks  and his work in this area had an influence on Sir Isaac Newton  as he developed his particle theory of light. Huygens Principle Definition The Huygens principle of wave analysis  basically states that: Every point of a wave front may be considered the source of secondary wavelets that spread out in all directions with a speed equal to the speed of propagation of the waves.What this means is that when you have a wave, you can view the edge of the wave as actually creating a series of circular waves. These waves combine together in most cases to just continue the propagation, but in some cases there are significant observable effects. The wavefront can be viewed as the line tangent to all of these circular waves. These results can be obtained separately from Maxwells equations, though Huygens principle (which came first) is a useful model and is often convenient for calculations of wave phenomena. It is intriguing that Huygens work preceded that of James Clerk Maxwell by about two centuries, and yet seemed to anticipate it, without the solid theoretical basis that Maxwell provided. Amperes law and Faradays law predict that every point in an electromagnetic wave acts as a source of the continuing wave, which is perfectly in line with Huygens analysis. Huygens Principle and Diffraction When light goes through an aperture (an opening within a barrier), every point of the light wave within the aperture can be viewed as creating a circular wave which propagates outward from the aperture. The aperture, therefore, is treated as creating a new wave source, which propagates in the form of a circular wavefront. The center of the wavefront has greater intensity, with a fading of intensity as the edges are approached. It explains the diffraction observed, and why the light through an aperture does not create a perfect image of the aperture on a screen. The edges spread out based on this principle. An example of this principle at work is common to everyday life. If someone is in another room and calls towards  you, the sound seems to be coming from the doorway (unless you have very thin walls). Huygens Principle and Reflection/Refraction The laws of reflection and refraction can both be derived from Huygens principle. Points along the wavefront are treated as sources along the surface of the refractive medium, at which point the overall wave bends based upon the new medium. The effect of both reflection and refraction is to change the direction of the independent waves that are emitted by the point sources. The results of the rigorous calculations are identical to what is obtained from Newtons geometric optics (such as Snells law of refraction), which was derived under  a particle principle of light- although Newtons method is less elegant in its explanation of diffraction.

Analysis Of City Of God - Essay Example However, the government strives to put up with the bulging population pressure by establishing a housing project in the outskirts of Rio. Nevertheless, the demand is so high and with housing being considered a luxury by a section of the citizenry, slums start to develop in the city.Global cities are defined as cities with huge impacts and influence on the development of the global economy. Rio de Janeiro is one of the global cities as depicted in the film ‘The City of God'. During the 1960s, Rio was experiencing rapid economic progress and had numerous economic activities. This was largely attributed to the city's beauty, cultural diversity, attractive beaches and the globally renowned landmarks. Therefore, the city attracted a huge number of tourists leading to increased business and expansion. However, Rio, like all other global cities experienced varying challenges which ranged from insecurity, huge gaps between the affluent and the underprivileged in society among other pro blems. Resultantly, this is one of the reasons why urban planning in global cities is a difficult activity.Education is a crucial tool for personal development and intellectual growth. A nation that invests wisely in education easily manages to move ahead in most aspects of its development such as the economy. In the ‘City of God', people are quite ignorant and skeptical of embracing education despite being accessible to them. For some, however, they are eager and cooperative in trying to attain formal education.

Site Contamination - Derby Pride Park Research Paper

Site Contamination - Derby Pride Park - Research Paper Example The paper tells that soil pollution is a very critical health related issue. Both soil pollution and groundwater pollution adversely affect the health of humans, plants, and marine life. â€Å"Soil contamination can also affect those who touch it†. If we talk about groundwater pollution, we can say that it is even more dangerous because it directly affects human as well as marine life. Discharged water contains such substances, which are very harmful for the health of human beings. Before going to propose a site decontamination plan for the Derby Pride Park, let us get a brief overview of sources of contamination and some methods to decontaminate the polluted sites. There are various sources of contamination production. These sources include food, dietary supplements which are very rare, drugs, industrial discharge from chemical industries, pesticides that come from farming areas, and various detergents and fertilizers. â€Å"The potable water becomes wastewater after it gets contaminated with natural or synthetic microbiological compounds†. Groundwater from the neighboring fields is also a source of contamination. â€Å"Groundwater moves slowly and continuously through the open spaces in soil and rock†. Another major source of contamination is those chemical processes, which are used to take out the required minerals from rocks because raw material containing the minerals is often stored in impure and contaminated surfaces, which results in contamination of minerals. So it is strictly advised to keep the surfaces clean on which the raw material is to be placed. Remediation Remediation means decontamination of the polluted sites. The process of

A simple constant pressure calorimeter was produced out of two styroform cups. The cups were covered with a plastic lid with a hole in centre. While erformiing the acid-base neutralization reaction, the temperature of both acid and base were measure using PH metre temperature probe. The temperature were about each other. When HCl was added to NaOH no visible change was observed while adding the acid. But the temperature of the soluction was rise after the acid was added. This showed that the reaction between HCl and NaOH was exothermic reaction. after that mass of the final solution was measured. The second objective was to find the heat of the reaction per mole of calcium metal, while following the hess’s law provided in the lab manual. This was done in two different trials. First the calcium metal was added to 50.0 ml of 1.0M HCl and then 50ml of water. When calcium was added to HCl it reacted vigorously creating bubbles. The highest temperature recorded was almost double the initial temperature. When water was added to this solution, no visible change was observed, but temperature was dropped by 10 degC. The overall process was still an exothermic reaction the heat of the reaction was calculated to be -190.372 KJ/mole In the second trial, the calcium was first added to water. This reaction was similar to the first one. Calcium reacted with the water vigorously. The temperature of the solution was increased showing that is was exothermic reaction. when HCl was added to this solution the temperature was dropped by 3.6 degC. Which was less than the first case. The heat of the raction waw calculated to be -213.81 KJ/mole. The closeness o fthe both results can be explained by the fact that heat of the reaction is a state function, and does not depend on the path of the reaction. this also increases the confidence in the result. The final objective of the reaction was to determine the heat of dissociation of the unknown salt, and thus find the unknown salt by comparing the heat of dissotiation to the heat dissolution of possible salts. This unknown salt code C was white powder form. When unknown salt was added to water, temperature raise by 7.1 degC. This reaction showed that this was a exothermic reaction. the average enthalpy of dissolution of the unknown salt C was calculated to be -764.67 J/g. This value of enthalpy of dissolution corresponded to the calculated value of Lithium chloride, LiCl. A number of experiment errors could have affected the data collected, which includes the accuracy and precission of the instruments used environment conditions. The graduated cylinder was used to measure liquids was accurate to only one decimal place, or could only round the value to .0 or to .5. the measuring balance used to weigh had had high accuracy up to three decimal place, dispite that there was difference in the total weigh of the soluction in all three trials. This shows that may be weighing machine was not accurate. it is also possible that when solution was shaked to mix the reactant some of the solution lost or may be was left over on the cover lid. Or into the walls of cups and glass container. While doing the experiment some liquid was spilled that could be that reason for the difference in the weight. The volume of the solution could be measured by burettes or pipetts for higher accuracy. Overall the results of the experiment calculations were really promising and confident based on the fact that they folled the theory of the experiment. Conclusion: A calorimeter was prepared. The heat capacity of calorimeter was calculated to be 29.73 J/deg C. The heat reaction calcium was found to be -190.372 KJ/mole and -213.81 KJ/mole, in the two trials. the unknown salt had -764.67 J/g salt. The unknown salt C was found to be Lithium chloride. Results of this experiment is promissign and confident. References: Olmsted, john 3; Williams, greg; burk Robert c.

Wordsmith and The Gold Mountain Coat

The poem â€Å"Wordsmith† is talking about a boys father who is constantly working on their house. To perfect it. It mentions how he â€Å" he fills and smooths and sands as filling in all of the empty crevices. † While the boy is watching though I can sense some sadness, maybe for the fact that his father spends more time on the house rather than with him. He might feel as if the imperfections of the house are more important then him. The short story â€Å"The Gold Mountain Coat† is about a father named Sam sing. Sam has an rugged appearance it states that he rarely smiled or even talked for the matter. Sam has two sons Ken and john. He was proud of the fact that when he was unable to look after the chines restaurant anymore he would have to sons to take over. Sam seems very unfriendly. He never visited the other family with his son. His life seemed to be devoted to the restaurant rather that to his family. The similarities between the fathers in the â€Å"Wordsmith† and â€Å"The Gold Mountain Coat† would have to be that they both work very hard. I think that they do it for their families. To show that they care deeply and want to provide a nice place to live and help sustain a good life. In â€Å"Wordsmith† is says that the fathers â€Å"love keeps him moving from room to room†, meaning that he does it out of love although it may come off as if he doesn’t care. In â€Å"The Gold Mountain Coat† it shows that he actually has a lot of love for his family and works hard to provide for them even though it may not seem as it and that the sons are afraid of him. When john asked for a second coat for him and his brother and that his son could grow into it Sam said yes. I think that shows a lot of love. Both fathers are very caring and both do everything out of love.

Amyotrophic Lateral Sclerosis is a disease that affects the Nervous system as well as the Muscular System as well, this disease is defined as a progressive neurodegenerative disease that affects the nerve cells in the brain and the spinal cord. A-myo-trophic is a Greek term when translated it means â€Å"No muscle Nourishment†. This lack of nourishment causes a reaction within the muscles leading to their eventual break down, otherwise known as â€Å"atrophies† which is a simple term meaning that the muscle wastes away. When looking at the term â€Å"Lateral†, this is in reference to the section of spinal cord in which the nerves are being affected. While this area degenerates it will lead to eventual scarring and hardening within this region (this is†¦show more content†¦(Lights,2016),(ALS,2016) The Brain and the Spinal Cord are both components of the nervous system. The nervous system is what carries messages from the brain to the spinal cord and then sends these messages to various locations within the body. The nervous system is comprised of two systems, the first being the Central nervous system. The Central Nervous system is comprised of two main components which are the brain and the spinal cord. The second being the Peripheral Nervous System which is comprised of the autonomic and somatic nervous systems. The Brain is divided into four main parts, the brain stem, the cerebellum, the cerebrum and the diencephalon. Within the brain there are two types of matter the Brain Grey matter, which is responsible for receiving and storing impulses (cell neurons are located in the grey matter), and White Brain Matter, which carries the impulses sent by the Grey Brain Matter. The brain stem is what connects the brain to the spinal cord and is otherwise known as the medulla oblon gata. There are other components that comprise the nervous system such as meninges (Three layers of membrane that cover the brain and spinal cord, they act as protection to the brain and spinal cord against bacteria and microorganisms) and neurons which are comprised of

The Use Of Cognitive Behavioral Therapy ( Cbt ) - 1543 Words

This brief proposes three policy options that show the most promise for reducing depression in college students which are: increased state funding of programs that use cognitive behavioral therapy (CBT), expansion of mental health benefits legislation to non-parity states and school-based student health plans, and voluntary regulation of collaborative care models on college campuses through increased state funding linked to mental health outcomes. Policy Option 1- Selective prevention program of CBT The Coping with Stress (CWS) course has been developed as a youth at risk group program using CBT that empowers students to reduce maladaptive negative thinking in small group contexts administered by social workers and psychologists [14]. In an effectiveness study, the CWS participants â€Å"reported fewer depressive symptoms† and one-year later only â€Å"9.3% of the teens in the CWS program [were diagnosed for] major depression, compared with 28.8% of the teens in the control† [14]. A follow-up test is scheduled to determine the longitudinal effects of CWS programs and CBT approaches to youth depression [14]. CBT shows short-term effectiveness and can increase student academic performance and future employment productivity [6,15]. Estimated impact: This policy is expected to produce up to a 50% reduction in depressive symptoms in adult participants and will reduce the probability of psychosis transition among depressed students to about 10%, compared with 23.8% in regular careShow MoreRelatedCognitive Psychology : Cognitive Behavioral Therapy1447 Words   |  6 PagesCognitive Behavioral Therapy Djiedjorm Doe (Dede) Middlesex Community College Cognitive behavioral therapy, commonly known as CBT, is a systematic process by which we learn to change our negative thought into more positive ones.
