I wanna you to ready that and answer those two question. I dont want you to ready from anywhere else just ready the article that I am going to send to you - Case Study Example Such materials become considered inappropriate for use in joints. Mechanical characteristics – these materials must exhibit characteristics which enhance the functioning of the particular component which they are used to make. Tensile strength of materials, for example, remains an important characteristic for materials used in making the femoral stem of the artificial joint. The mechanical characteristics are the main causes of failures commonly observed in these joints. Material density and reproducibility – this are an essential element of concern because of the need to make repairs to artificial joints that might be damaged. The prosthetic quality of the material must remain consistent in order to make repairing easy, should damage to the joint occur. Magnetism – when seeking to establish an appropriate material for artificial hip replacement materials it is important to consider the magnetism of the materials. Material utilized for this function should not exhibit any ferromagnetic behaviors (Gibbons, 33). This is mainly because of the requirements to use MRI spectroscopy to study the joint in future. Magnetic materials make this spectroscopy method inapplicable. Toxicity – artificial materials sometimes produce toxic substances which could affect the body parts. The reaction of some materials with the body parts commonly results in the generation of toxic substances which harm the body parts next to the artificial implant. Femoral stem – the femoral stem fits into the femur bone. There is need to make considerations of the corrosion characteristics of the materials which are utilized in the manufacturing of the femoral stem. Cobalt chromium and titanium are the major alloy components for the material which is utilized for making this component. This alloy remains highly resistant to corrosion and fatigue which results from increased use of the

Disclosure and Financial Reporting Essay Example | Topics and Well Written Essays - 2250 words

Disclosure and Financial Reporting - Essay Example It also helps the other market players to decide on mergers and acquisitions. Through disclosure of financial statements, the companies also endorse the financial information that has been sent to their regulating authorities like Securities and Exchange Commission (SEC). It is important to understand the key issues that affect the financial decisions of managers in disclosures and financial reporting. In this essay, the changes in regulations and standards that have improved the method of financial reporting and disclosure and the subsequent impacts on a company in terms of future cost, risk exposure and profits are being discussed. Several laws have been enacted and acts have been passed in different countries with the objective of making financial reporting and its disclosures more reliable and trustworthy. The objective of addressing the key issues is to ensure and protect the interest of the stakeholders and investors. One such act that addressed these issues is Sarbanes-Oxley A ct. It was first implemented for companies listed in NYSE and has now been spread all over the world. Sarbanes-Oxley Act has redefined and changed the ways of Corporate Governance of companies leading to efficient and transparent operations (Ambler, Massaro and  Stewart, 2005, p.38). ... Many investors had previously complained about the relevance and volume of financial information in their disclosures and were also unhappy of finding useful information in the disclosure and financial reporting by companies. In the above context, SOX was enacted in order to make it mandatory for companies to certify accuracy and relevance of the financial information disclosed by them. Non-adherence to SOX Act also earned penalties for the companies. The enactment of SOX has empowered the external auditors and has increased the role of oversight for the concerned Board of Directors. The change in role of the Board of directors has redefined corporate governance by making it stricter than earlier. Through efficient corporate governance, the companies were able to deal with the new system of laws and regulations and maintain healthy relationships with their stakeholders (Rao, 2000, p.42). The continuous monitoring of the board of directors helped in eliminating the misdeeds or misappr opriations in the part of corporate officers. As a result of these changes in regulation, the following key issues were addressed. Proper system of accounting and financial reporting was put in place which enabled disclosure of only and only relevant information to the stakeholders of the company. Secondly, flexible requirements were put in place for the companies to report relevant information for some specific circumstances. Thirdly, a judgment panel or framework was instituted to decide which information is pertinent with respect to specific situation faced by the companies. Fourthly, suitable techniques were adopted in order to make information more user-friendly and easy to find for the readers.

Another breakthrough was that of Charles Lindbergh who flew and completed a journey across the Atlantic Ocean in 1927. The United States postal service as well contributed to the aviation/airline growth. Kelly Airmail Act allowed transport mails from one destination to another in 1925. There was a major issue with increase in air collision which brought about an Act by the Federal Aviation Administration in 1958. Another discouraging issue was the increase in the price of fuel in the 1970s. During the early 1980s there another deregulation was introduced which brought about mergers of large carriers and growth of smaller ones.

(2003) SNAP SHOT OF SINGAPORE AIRLINE http://s3files.core77.com/blog/images/sa3803.jpg From www.google.com/singaporeairlineimages Comfort ability FIRST HAND DATA Through the means of email and telephone interview, I was able to collect the following first hand data directly from the public affairs department in Singapore from the 5th to the 9th of September 2009. Question 1: Since its establishment, Singapore Airlines has earned a reputation as an innovative market leader, combining quality products with excellent service. In brevity, please explain the history of Singapore airline since its early days from 1947 till date? Answer: A Brief History The Early Days Singapore Airlines history can be traced back to 1st May 1947, when a Malayan Airways Limited (MAL) Airspeed Consul took off from Singapore Kallang Airport on the first of three scheduled flights a week to Kuala Lumpur, Ipoh and Penang. Over the next five years, larger capacity DC-3 aircraft were introduced. This meant faster and more comfortable flights, and the extension of services further afield to destinations in Indonesia, Vietnam, Burma (now Myanmar), North Borneo (Sabah) and Sarawak. Inflight refreshments improved from the original thermos flask of iced water to sandwiches, biscuits and cold cuts plus a choice of hot and cold drinks, and alcoholic beverages served by a lone hostess. Known as female pursers, these hostesses are the forerunners of todays Singapore Girl. The 1950s 1960s More new aircraft were added to the fleet in the 1950s and 1960s, the period leading up to the jet age. Among these were the DC-4 Skymaster, Vickers Viscount, Lockheed Super Constellation, Bristol Britannia, Comet IV and Fokker F27. On 16 September 1963, the Federation of Malaysia was born and the Airline became known as Malaysian Airways Limited. In May 1966, it became Malaysia-Singapore Airlines (MSA). In 1968, for the first time, annual revenue hit S$100 million. The sarong kebaya uniform for air hostesses, designed by French couturier Pierre Balmain, was introduced and three B707s were added to the fleet. The Airlines Boeing age began in 1969 with the purchase of five B737-100s. The 1970s The 1970s got underway with a bang: on 2nd June 1971, MSAs first transcontinental flight took off for London. In 1972, MSA split up to become two new entities Singapore Airlines and Malaysian Airline System (MAS). The rest of the decade was devoted to growth and consolidation of the newly-established Singapore Airlines. The fleet was expanded to include B747s, B727s and DC10s. To provide more efficient ground services at Paya Lebar Airport, a subsidiary company, Singapore Airport Terminal Services (SATS) was set up. A B747 hangar and airfreight terminal was opened in 1977. The 1980s The move to the new Singapore Changi Airport from Paya Lebar on 1st July 1981 was a big event. Two years later, Airline House, Singapore Airlines corporate headquarters in the Changi Airfreight Centre, was officially opened. The first Singapore Airlines A300 Superbus went into service in February 1981 and the first B747-300 in May 1983. The first B757 and the first A310-200 arrived in November 1984. In 1989, Singapore Airlines became the first airline to operate a B747-400 on a commercial flight across the Pacific. Tradewinds, a Singapore Airlines subsidiary, became Singapores second airline in February 1989. It has since been renamed SilkAir and has an established network of 29 destinations in the region. The 1990s Singapore Airlines commenced operations from the new Terminal 2 at Singapore Changi Airport on 22 November 1990, with the arrival of SQ23 from Amsterdam. In September 1998, Singapore Airlines set new standards in air travel by unveiling a new suite of product and services worth S$500 million across all three classes of travel, offering customers enhanced standards of service on the ground and new levels of comfort, cuisine and entertainment in the air. In 1999, Singapore Airlines launched KrisFlyer, its first proprietary frequent flyer programme, which allows First, Business and Economy Class customers to earn mileage credits. The 2000s In February 2004, Singapore Airlines inaugurated its first Airbus 340-500 by setting a record for operating the worlds longest non-stop commercial flight from Singapore to Los Angeles. The Airline bettered the record barely half a year later, in July 2004, when it launched the non-stop Singapore to New York (Newark) flight. Singapore Airlines currently operates 77 Boeing 777s, consisting of 12 B777-300s, 19 B777-300ERs , 31 B777-200s and 15 B777-200ERs.

On 15 October 2007, Singapore Airlines took delivery of the worlds first A380 at the Airbus Headquarters in Toulouse. Singapore Airlines was the first airline to operate out of Changi Airport Terminal 3 in January 2008. The Airline currently operates out of both the new terminal and Terminal 2. In May 2008, Singapore Airlines created history again by being the first carrier to operate an all-Business Class service between Asia and the USA with its launch of all-Business class non-stop flights from Singapore to New York (Newark). Three months later, in August 2008, the Airline introduced this all-Business Class non-stop service to Los Angeles. On 21 January 2009, Singapore Airlines received the first of 19 new A330-300 aircraft in Toulouse, France. The aircraft is configured in a two class layout, with 30 new Business Class seats, and 255 Economy Class seats.

Claydon, T Knowledge level system The knowledge level is to help the organisation in discovering, organising, and to integrate new and existing knowledge in to the business. Controlling the flow of paper work should be employed in this level as well. A classical planning system in terms of models of problem solving should be carried out properly and accurately. A high level of information system design is needed at this level. In the knowledge level, a biometric system can be employed in order to monitor the staffs attendance and for security purpose. This system would reduce the level of insecurity and intruders or unauthorised access into the company. The use of SAP (system Anwendungen und produkte) can be employed in Singapore airline to manage the system at the operational level. SAP is system software used to manage the system database.

Management level system The purpose of management level is to monitor and control, decision making, and administrative activities by middle managers. The management level is the decision support system unit where management information system should be used to carry out sales management, inventory control, annual budgeting and relocation analysis. is4 (By Lachlan Mackinnin and Phil Trinder) The management should be able to analyse regional sales, schedule production in such a way that time and cost of production will be will be managed by telling the production facility what to make with which staff, and on which equipment. This is done by using production scheduling tools. An inventory control system can be used, which is integrated package of software and hardware used in controlling the companys stock. The management level of SIA should be able to analyse cost quantitatively in order to decide whether to follow a course of action or not. In terms of pricing or profitability, the management should be able to conduct a proper profitability analysis in order to provide invaluable evidence concerning the earning potential of the company. Innovative system This level is being managed by senior managers to tackle and address strategic issues and long term trends. Senior managers do not only tackle issues within the organisation, they look into the external environment as well.

A Woman Who Is a Person in Kate Chopins The Story of an Hour Essay

A Woman Who Is a Person in The Story of an Hour  Ã‚     Ã‚   In her book, The Faces of Eve, Judith Fryer writes, "In the last year of the nineteenth century a woman succeeded where men had failed: Kate Chopin created . . . a woman who is a person." Chopin’s short story, "The Story of an Hour," openly portrays the true feelings of a woman who feels trapped inside her marriage. In the period in which she lived, there were only two alternatives for her to achieve the much desired personal freedom—either she or her husband must die! Chopin’s story was controversial from the beginning. It was rejected for publication by both Vogue and Century magazines as "a threat to family and home." Vogue later published the story only after another of Chopin’s stories did well publicly. "The Story of an Hour" begins with Louise Mallard being gently informed of her husband’s death in a train accident. Sister Josephine was careful not to upset Louise too greatly because of the latter’s heart trouble. Did Mrs. Mallard suffer from an actual physical ailment or an emotional, psychological trauma? I lean toward the second theory. Louise felt trapped inside her marriage—having no personal freedom—and the only way she could express this was through a physical illness. Mrs. Mallard weeps with "sudden, wild abandonment" and then disappears to be alone. Mrs. Mallard’s sister Josephine and Mr. Mallard’s friend Richards believe she needs to be alone in her grief. She retreats to a comfortable chair in front of an open window—a place the reader is led to believe she frequently spends time in. As physical exhaustion overtakes her, Mrs. Mallard can do nothing but gaze at the scenes taking place outside the window. Strangely, the things she sees are not ... ... or her husband? Now that Louise had tasted freedom, she could not bear the thought of returning to her dreary life. In the split second that she realized her husband was alive and any hope she had freedom was gone, Louise’s heart decided what must be done. He was alive, therefore she must die.

Formal And Informal Assessment And Evaluation Education Essay

Appraisal and rating has become critical issues particularly in the field of learning and larning ; it requires alert consideration by every instruction practician in any educational establishment. This is besides the country where many instructors sink into the pool of confusion. But it has its cardinal map, which is to roll up information on the accomplishment of every single pupil and judge their mundane advancement. In other words, it serve critical function in the procedure of effectual instruction and acquisition. Therefore, this essay will explicate my apprehension of appraisal and rating from the positions of development, formal, informal, particular demands, and criterions in brief. However, to make this, we foremost need to specify appraisal and rating. The word appraisal is derived from the Latin word ‘assidere ‘ significance ‘to sit beside ‘ . It is obvious that simple tone of this phrase is comforting, and it suggests common assurance and apprehension. So, it indirectly tells that being of positive association between appraisal and the procedure of instruction and acquisition in schools is necessary. By and big, appraisal is a procedure of roll uping information relation to some identified purposes and aims involved with pupils ‘ advancement and accomplishment in the procedure of instruction and acquisition. More specifically, schoolroom appraisal refers to the procedure of assemblage, entering, construing, utilizing and pass oning information about their advancement and accomplishment during the development of cognition, constructs, accomplishments and attitudes. Harmonizing to Lloyd-Jones and Bray ( 1986 ) appraisal is referred to the procedure in which certain quality of a pupil ‘s instruction is measured, by the instructor, an tester or the pupil. It is means to mensurate worthiness of pupils ‘ public presentation. Assessment, hence, involves much more than proving. It is an on-going procedure that encompasses many formal and informal activities intended to analyze and better instruction and acquisition in all countries of the course of study. On the other manus, rating is more or less defined as the procedure of judging comparative virtue, value, or worthiness of educational plans, or techniques by utilizing realistic information generated through appraisal. It helps in updating the nature and grade of acquisition ; plays polar function in curricular determination devising ; and it favour better links between acquisition, and the purposes and aims of learning. Furthermore, it creates strong bond between larning and the environments in which larning takes topographic point. Therefore, in educational scene, appraisal and rating seeks grounds that the acquisition activities designed for pupils are effectual.Appraisal and Evaluation from the position of developmentWhy do we measure and measure? This is the first inquiry that knocks in my head whenever I look assessment and rating from an angle of development. Generally, instructors plays critical function in developmental appraisal and rating of pupils ‘ acquisition and plans for many grounds: First, appraisal and rating aid instructors and pupil matter decision makers to heighten their apprehension of the demands of a persistently changing pupil population. In add-on, it will assist in placing developmental holds in pupils and to develop schemes for intercession. For that, I would prefer to utilize the construct of incorporate theoretical account of kid development. It is because the theoretical account covers up all developmental countries such as sensory, behavioral, linguistic communication, motor, perceptual, societal cognitive and emotional accomplishments. So it can besides be used to better holistic development of pupils as a pupil, ego, and valuable citizen of the state as it reflects their personality every bit good as their grade of accomplishment in the field of acquisition. Second, appraisal is besides meant to develop efficient educational institutional programs and policies to run into pupils ‘ developmental demands and acquisition manners. They are important for progressing the quality and easy handiness of plans and services. Third, we can non avoid its greatest part in course of study development. Through appraisal and rating, we will be able to assist course of study developers for make up one's minding how we might better classs and programmes. At the same clip, as a instructor we can lend in making alteration on course of study, class stuffs, learning methodological analysiss, etc. It is because assessment consequences can specially supply a powerful rational for procuring scaffold for course of study alterations, development and reappraisal.Formal and Informal Assessment and EvaluationA formal appraisal is besides sometimes known as summational appraisal. And it is by and large assessed in the signifier of quiz, trial, or paper and is graded based on how good pupil is able to execute. A summational appraisal is usually carried out at the terminal of unit or faculty. Furthermore, formal appraisals are categorized into criterion-referenced trials and norm-referenced trials. Criterion-referencing is assessment based on certain standard or rule, and norm-referencing is graded appraisal based on the comparings of scholars ‘ accomplishment against one another from clip to clip. I prefer more of standard citing method than norm-referencing because it can be used to judge pupils ‘ accomplishment and advancement on a series of cardinal standards set based on moderately expected acquisition results and aims. Whereas, norm-referencing is based on the hypothesis, that a more or less similar scope of human public presentation can be anticipated for any pupil group. On the other manus, Informal appraisal is referred as formative trial, and it is a uninterrupted procedure of appraisal and rating. Feedback plays critical function here as it allows both scholars and instructors to measure acquisition and topographic point out the countries for betterment. But which one could be the best signifier of appraisal, formal or informal? In my sentiment, the usage of informal appraisals is best for the overall acquisition. It facilitate instructors to assess pupils through a scope of classroom-based activities, place pupils failing so and at that place and get down work for the betterment, instead than waiting at the last minute like informal appraisal.Appraisal and Evaluation for particular demands pupilsStudents ‘ holding jobs such as: motor, lingual, cognitive, behavioral, organisational, address and physical disablements are normally referred as particular needs pupils, and it besides includes talented pupils. They should non be left out without normal instruction. Particular agreements or particular demands adjustments should be offered to them in order to prosecute their academic ends and accomplish a higher degree of personal autonomy. Similarly they besides need to be evaluated and identified their strengths, failings and give guiding rules to do effectual advancement in achieving their academic ends. Other than instructors and equals, pupils ‘ household should affect in it. So, I feel that, by constructing an confederation with their parents ; obtaining pupils ‘ developmental history and current household experience ; and discoursing issues with them would assist greatly for turn toing challenges in steering particular needs pupils to win like other normal pupils. Furthermore, rating will be holistic and addresses all facets of operation. For that we should non bury to take pupils ‘ single acquisition manners into history as all pupils do non hold same learning capableness and ways. Sometimes pupils with particular demands are integrated in regular schoolrooms because the chief thought of appraisal and rating in this field itself is to see whether a pupil is able to accommodate, do advancement and met aims in normal category like normal pupils. Assessment indicates whether the pupil learned the stuffs intended and what are some of the drawbacks countries to be improved. So schools and teacher must give all pupils an equal chance to instruction. Infect, they should supply counteractive aid to particular needs pupils. Never the less, we as a instructor, in order to choose instruction plan and activities suited for our pupils, we must carefully measure our options and see the particular needs of our handicapped pupils. Standards based Assessment and Evaluation Here, it includes two types of educational criterions, a content criterion and a public presentation criterion. A content criterion defines the cognition, constructs, and accomplishments get at each class degree, while public presentation criterion province the degree of public presentation that is considered acceptable alining to the benchmark set by the instructors. Standards-based appraisal and rating is meant to place pupils with different gait and capablenesss in acquisition, so that we can plan schemes to assist them and do all of them achieve and maestro to the degree that they are required to retain certain benchmark in acquisition. Understanding ‘Standardized Test ‘ and its features is necessary when we discuss about appraisal and rating from the position of criterion as it is one of the instrument required in standard appraisal and rating procedure. Range of cognition and apprehension in specific topic is being assessed through standardised testing on pupils. And it is a snapshot in clip where appraisals are administered and scored in the same manner for all pupils. For illustration, multiple-choice inquiries and written responses to be answered within a given clip frame are illustrations of standard trial. That means pupils are non allowed to utilize outer resources or mentions in order to finish the trial. Their public presentation on these trials decides whether they will be promoted or non from one class to the following. And this is what about every school territory now administers it. However, it is of import for us non to acquire confused of Standardized trials with the criterions motion, which approve definite grade-level content and public presentation criterions in chief topic sphere. Frequently, regulated unvarying trials are non associated with province and territory content criterions, and these causes perceptibly lose of connexion between what is being taught and what is being tested. So as a instructor we have to treat our learning harmonizing to the course of study. The standard rating will enable other school betterment program and undertakings, and to convey progress alterations in course of study and teaching method, and incorporation of new appraisals. So standardised appraisal and rating is uniformly regulated trial which it refers to when every pupil at a peculiar class degree has to undergo the same trial with same inquiry, at same clip frame in same twelvemonth throughout the state. In the nutshell, we would happen that the descriptions given in above paragraphs are all positions from different positions constructed by speculating the both particular needs pupils and normal pupil as an active in structuring their ain acquisition in the context of societal interaction ; function of educational establishments and instructors in set uping the kid ‘s phase of development in any facet of acquisition, and that information collected through assorted appraisal and rating methods will so be used to ‘scaffold ‘ the following acquisition and course of study development.

Creative writing Essay

‘Now this is a story all about me, when my life got twist turn upside down, if you like to take a minute just reading right here, I’ll write you how I became a prince of a town called New Jersey’ could you find a word that rhymes with New Jersey? ‘In East London I’m born and raised on a playground is where I’ve spent the most of my days chilling out, relaxing all cool and all kicking some football outside of school when a couple of guys, they were up to no good started making trouble in my neighbourhood I got in one little fight and my mum got scared and said â€Å"you’re moving with your aunt and uncle in New Jersey here, have this Hershey’ that kind of rhymes. If you didn’t know Hershey is a chocolate bar that is sold in America. Although I would like to think that I was the fresh prince, my story didn’t exactly start out like that. Instead of my parents sending me to my relatives because of academic problems, I went because I have been nagging them for a really long time. I’m not saying that my academic level was reaching its fullest potential before I went, but the main reason I went was to have a taste of things to come. For as long as I can remember I have always wanted to live in one of those semi-detached American houses with the large front garden, golden retriever, two kids and a large garage. When most people watch American films they are focused on the storyline, but when I watch them not only am I watching the story, but also at the back of my mind I am constantly absorbing the American background. Finally in the summer of 2000 July 3rd, I got the chance to have a taste of my dream. Even though it was just a small taste, it was enough to last me however long it will take to finally move there. When my parents did decide that it was o. k. to send me there, it was there idea of making me have a taste of the ‘real world’. There idea of a taste of the ‘real world’ was my idea of a taste of a dream. At the time I had just finished my GCSE’s, and my grades were not that great. My parents had planned that America would change my course; I guess it did in the end but my biggest change was with my personality. When I did return I felt more confident, independent, funny and larger (thanks to those large American portions of food). Everything leading up to the day I left flew by and before I knew it I was in the airport sitting at the waiting room with my dad. I remember my dad being really calm and cool about everything, he never really got sad in front of me especially with good-by’s. He told me stories about when he went to New York for the first time: ‘Now this is a story all about your dad, back in the day I also was bad, Your old man also had the American dream, thinking that it would be so cool and supreme, I stayed there for a while to learn the truth, that America was best lived in the movies, ‘what a poof! ‘ I never knew my dad could rap, looks as though he has a problem with finishing it as well. To sum up my dads rap; he also had the American dream being brought up on James Dean movies. Throughout his teenage years he had dreamt up an image of what America would be like, unfortunately when he stayed there, it did not match his dream. That is how my dad tells the story, but I think there’s something he is not telling me. I also believe that my parents don’t want me to live far away from them because they regret moving far away from their parents when they were younger. On the plane, I sat next to an empty seat, which wasn’t bad as I wasn’t really good with the airplane conversations. I travelled on Virgin Atlantic and the in-flight entertainment was great, they had a video screen in front of each seat with which I could play games, watch films and programmes. Anyway back onto America, I remember as we approached the New York coast I heard a passenger in the seat in front of me, â€Å"look there’s the statue of liberty† I looked to my right out of the window and saw her. She was a bit smaller then I had imagined (in Ghostbusters 2 she was huge! ), and she was green. I never actually realised that she was green before; I always thought she was grey. I wasn’t disappointed though; looking at the New York skyline for the first time was great. However I still felt as though I was in England, maybe it would change when we land. After I collected my luggage, I went through the inspection terminal where policemen checked your passports. I found this strange but the strangest was to come, when I reached the gate where my aunt would be waiting for me. Oh yeah if I didn’t mention it before, I would be staying with my auntie there, like my parents were really going to let me stay there by myself. Anyway along with the story, the last time I saw my aunt was when she visited England when I was 2 so†¦ I was the first out into the arrival room and there was a crowd so large I felt like I was in one of those ‘where’s Wally’ books. I looked at the crowd and then a man taped my shoulder and pointed out my aunt to me. They were waving out to me trying to get my attention with a big sign with my name on it. I said thanks to the first American I made contact with and walked over to them. We did the usually Portuguese custom and did the kiss on the cheeks thing. I originally thought that communication between us would be easy, but boy did I wish I brought my translator. They could barely understand me, and the fact that my ears were still popped from the plane journey didn’t help either. I felt like a deaf, posh Wally (as in Where’s Wally). The next day when I woke up, I had that weird feeling when I wake up in a different room and don’t know where I am (it was like that film Memento). Then I got up and looked at the picture of ‘the statue of liberty’ on the desk and remembered when I was on the plane. I woke up to Independence Day and before I knew it I was on my way to a barbecue. It was a beautiful sunny day and boy was it hot! I wore light cloths but it was way hotter then I thought it would be. When I arrived there I met ‘The Martins’, they suited the typical average American household family everything apart from the golden retriever. Not that my aunt and uncle didn’t suit the typical American household image, but they lived in an apartment which was more like an episode of ‘Friends’. At the barbecue I ‘piged’ out big time, I don’t think I have ever eaten so much in such a small time. I even got to drink my first bottle of Budweiser, I never really liked beer but after that I had chosen my favourite drink. I had also bonded really well with Bruno Martin and his friend Chris. Bruno showed me his loft that he lived in under his house; he had his own shower, living room. After the barbecue we went for a drive in the city, on my second day I was already in New York. We drove around for a while, but there was too much traffic so we had to stop and park near the Brooklyn Bridge (it was in the end of ‘Godzilla’). From there we watched the fireworks, there were lots of people that were watching with us. After that we finally drove into the city and walked around in ‘Time Square’ (too many films too mention). I have never seen so many people from different countries in one place. That night I slept well knowing that when I wake up tomorrow I will definitely know where I am. A couple of weeks later I went out with Bruno and Chris again for a whole day out. First up was a visit to his high school, where we would play baseball on the field. I was looking forward to seeing what his school looked like, after all those years of seeing a typical American high school in TV programmes. It was huge and the sports facilities were expensive. They had a huge football field (as in American football), and three outdoor tennis courts! It made the sports facilities back at my school look basic. We played baseball on the field, which is when I began to really feel American. Bruno and Chris were impressed with my skills, especially as I had hit more home runs then both of them. After that we went to the beach, which is when I began to feel as though I was David Hassolhof in an episode of Bay watch. The weeks generally flew by, however there were some bad weeks when things were just going all wrong. When my aunt leaves for work each morning she would leave something that I could pop in the microwave. I however was not to sure on the rules of using a microwave and used a non-microwave plastic container to re-heat some chicken from the night before. I was just watching TV eagerly anticipating my meal, when I smelt smoke. I rushed into the kitchen; smoke was everywhere, opened the microwave and saw that the container had melted with the chicken inside it! I threw it into the bin opened all the windows and turned the A/C to full power. I went for the air conditioner, hoping that I could diminish the smell of burnt plastic. When my aunt returned from work she could smell the burnt plastic straight away but thought that maybe the dogs litter tray needed to be cleaned out. I actually thought that I might get away with it until my mum realised the burn stain in the microwave, DUM DUM DUMM (that was meant to be when in movies when something bad happens). She caught and shouted at me for having both the windows open and the A/C on. If you think that was bad, that is nothing compared to when I was taking Pepper (our dog) for a walk and a huge dog attacked him. That was really scary, the owner of the big scary dog, couldn’t even release his own dog. The dogs jaws were looked tightly on Pepper’s neck all I could was watch. Luckily Pepper survived and was treated for minor bite wounds. Towards the end of my visit my vacation began to look up greatly. I visited New York more often and went on the Statue of Liberty and on the World Trade Centres. I remember when I went to the twin towers the tour guide on the lift told us that the lift was travelling at 30 mph (or something like that) and I could feel my feet feel light as we got closer to the top. The top three floors were accessible to tourists including the roof. To get to the roof you would take a escalator, all you could see when you were going up was bright blue sky and I felt as though when the escalator reached the top I would go over the edge. When I finally plucked up the courage to get on the roof the view was beautiful. You could see for miles, all the wonders of New York were in view from one place. When I returned showing my photos from the roof, my friends thought that I was on a helicopter. On my visit to the big green woman, I actually realised clearly how large she was up-close. I thought about how long she has been there for, everything she would have seen. Throughout seeing all the sites a common image would occur to me of re-visiting these sites when I move to America. For me New York was a place to visit not to live in. I have always wanted to live in the house from Home Alone, which is set in Chicago. I have always like the Christmassy look. Returning back to England was weird as when I went to America. Once again no-body could understand me (by now I have an American accent), I had to get use to the money as well. The weird thing about America is that when you get use to it you don’t even realise that you are living in America. Although you are use to it, you still notice differences here and there. My American dream is still there, its just a matter of until I make it into reality.

Houseflies in the Public Market Essay Example

Houseflies in the Public Market Essay Example Houseflies in the Public Market Paper Houseflies in the Public Market Paper Houseflies in the Public Market: Is there any life force presence in the air that accelerates the number of houseflies in the area? In relation to this, bare exposed meat and fish contribute the number of these species? By observing, obviously, there are large numbers of houseflies flew freely in the wet section of public market. They love to travel everywhere where bare meats and fish are exposed. They adore smelly places in every corner. Hypothesis and predictions: commonly protective windows and doors screens are practiced in the house to prevent houseflies. Their favorite hang-out is itchy odorous places. They accelerate most in open area where they can fly freely and past. However there is a high possibility that bare exposed meats and fish contaminate microscopic disease organisms. Houseflies might be the one of disease-carrier organisms Experimenting practiced and results:   A group of wide-mounted jars with a piece of raw materials (piece of broth) are subjected in different variations covers. Control group placed with sealed cover on the lid. The experimental group placed exposed and the other with top cover clothe on the lid of the jar. The results, jar with exposed lids has a large number of houseflies in the container. Jar with lid cover of clothe the houseflies gathered in the lid cover but none inside the container. Contrast to the sealed jar no houseflies had seen in the container. Testing: Different set-up, the raw material (broth) used in the experiment were boiled and sterilized, the containers/jars placed with different mouth shapes. Altogether the broth and jars were cooled and fresh, and placed in well-conditioned room. The set-up is different than before, control group were placed exposed. Experiment group placed with different mouth shaped.   As the result, specimen in control group spoiled in contrast to the experiment group. Under microscopic examinations, it found out that spoiled specimen exhibit bacteria contamination that causes odor and cloud forming in the specimen. Conclusion: the test shows no signs of life force presence in air that produce organisms only same organisms can produce identical organisms. No such explanations that bare exposed foods can produce houseflies rather they are one of disease carrier.   Each organism has specific habitat where they can survive, and accelerate. Appropriate habitat is the only place where organisms can produce and multiply safely and successfully. Biology is a science that affects our life every single moment and constantly in process. Earth is the only island of life.   Billion of years ago, from one single cell life spread across to the surfaced of the earth. It is very amazing to think how life formed. As generations past, many discoveries are followed in the wonders of life. The genius mind of Linnaeus discovered the two kingdoms, plants and animals. Today with the help of advance technology, six kingdoms are discovered and added. The six kingdoms: Plants, Animals, Protist, Fungi, Archaebacteria and Eubacteria. They classified and placed based on cell type, characteristics, and number of cells present in their body. Eukaryotes and prokaryotes are the ancestor of six kingdoms. Whereas two kingdoms under prokaryotes and four kingdoms into eukaryotes.

Are students have changed Essay Example for Free

Are students have changed Essay Our students have changed radically. Today’s students are no longer the people our educational system was designed to teach. (Prensky,2001). Prensky further stated that children in the 21st century are classified as Net-gen, and digital-gen but the most useful description Prensky found for these children is Digital Natives. This is evident because in the 21st century children as young as three years are mastering the uses of computers, videogames, internets, tablets, mobile phones and other technological devices. According to Janssen (n. d) digital native is an individual who was born after the widespread adoption of digital technology. Technology is so advance and useful to students it seems like they get so addicted to it and felt like they can’t do without it and the other hand it helps students to improve in learning. Three changes that are seen with the first century learner regards to technology, they are more dependent on technology, misuse of information and unlimited thinking skills. Firstly, the internet is known as one of the greatest invention of modern age; a gateway that is magical to resources, information and communication unlike anything we previous dreamed of. It is claimed by many that it is the greatest single technological advance for education, as it opens opportunities for studying, learning and discovering. But as time goes by and the first generation of students grows up with modern internet technology from birth to teenage years, questions have been asking are children being dependent on technology. The internet provides students with  enormous advantage of a world of information at their finger tip. A single tap of the finger on the keyboard can deliver a hundred of articles under a second; far hours from when students would spend time spinning through library books and journals in days passed by. With the ease of access, the internet comes with disadvantages such as false and incorrect information that is easily distributed and can be difficult to trace sources and support the information. On, on the other side the volume of research materials online can make students to find information they need too easy, allowing them to compile these information by copying and pasting without understanding and analysing the information they are sifting through at all. While students from twent y years and beyond would have to read and absorb a huge amount of information such as putting together a report on tree frogs. These students have to use different sources for each part of the project; while on the other hand digital natives would discover everything needed to know by the internet site, picking up a little knowledge in the process. According to Jannsen (n.d) people believes that children who are digital natives think differently due to their early exposure to technology and have become accustom to using technology to solve the repetitive tasks that form the basis of traditional learning With the rise of different technology, and the fantastic way that produce communication from mobile phones to iPods to Skype and face book, modern students have become available to a wealth of education opportunities. Pupils from Jamaica can now hold an online debate with a class of their contemporaries in United States and others, interactive group webpage, class blogs, and programs that design interactive online animations which allowed educational communication to form. The reliance on the mobile phones and the laptops is taking toll on areas in education such as literacy and writing skills. This is said to be suffering as children write less and more text message expression take preference over their grammar. Also the suffering of simple communication skills and understanding of personal interaction as young people spend more time online communicating using their keyboards rather face to face contact. The reliance of such method for communication can cause students to form unhealthy relationships with others, concerned about critics that was said, and open up possibilities of cyber-bullying that is very dangerous and persecution of people online. Secondly, the expansion of the use and easy  availability of technology makes it easy for society to do negative activities that often violates the law. The main problems are the misuse of copyright, distribution of forbidden materials, violation of privacy or personal data and other serious activities. This activity can be seen in education field where the increase of plagiarism among students. Students can find information on the internet free and plagiarize other’s work whether if it is intentionally or without realising it. According to Lindemann C(2013) among students in grades 7-12, 21% have turned in a paper downloaded from the Internet. More than a third (38%) copied text from a website. The more students rely on the internet such as Google and Wikipedia answers to answer their home work questions, they are required to use less of their minds to come up with independent thoughts and opinions. Instead they simple click, copy and paste. Plagiarism is not the only way of cheating. The internet is not the only way; students can used other technology such as mp3 players, mobile phones, calculators and other technologies. In gaining information using phones this can be done by emails, texts, Bluetooth, as well as phone calls. According to Takahashi (2011) many educators perceive them a slacking more formal ICT skills. The availability and ease of use of technology makes cheating possible. The environment opens possibilities for academic dishonesty which can be difficult to discover. Students find simple and fast way to get through their studies, such way is to share materials, results, papers, information about exams. A majority of website offers a variety of finished work materials for essays, seminar papers, reports, and even degree works, answers to test for final exams in bachelor or master courses. These website are made for students to upload their work voluntary and the provider usually do not get benefit from the sites; while some sites will offer small benefit for uploading the work. Downloading the work can also be free without registration, if not unless the provider creates a user account or a fee. The reason why students plagiarize is the overload of information. The more information you have leads to the first step towards good school paper. Technology is used by teachers and professionals to increase the quality of leaning. The growth and progress in ICT changes education compare to decades ago and introduce methods that increase in students learning. From this students need to learn how to deal with information for assignments,  work tasks, research tasks and other information problems. Thirdly, technology affects students thinking skill. According to Wolpert S (2009) as technology has played a bigger role in our lives, our skills in critical thinking and analysis have declines, while our visual have improved. Thinking is the ability to reflect, draw on conclusions, knowledge, reason and insight. It is what makes students communicate, build, create and become civilized. Thinking is based from learning, observing, remembering, questioning, arguing, judging and others. The exposure of technology as changes learners. Because of students’ brain still developing and malleable, the exposure of technology causes digital natives brain to be wire in ways different from previous generation. Reading encouraged the brain to be focused and imaginative; but pleasure for reading has decline in young people which enhances thinking and creates imagination that visual media such as video games, television cannot. The using of visual media will allow students to process information better but most don’t allow students to get the time to reflect, analyze or imagine. Reading develops reflection, imagination, critical thinking as well as the development of vocabulary. Through reading, these skills are developed. Students today are more visual literacy and are less print literacy thus many students are not being seen reading often and reading for pleasure. Technology strengthens student’s ability to scan information quickly and efficiently. An impl ication for teaching and learning is that workshops or seminars should be implemented for teachers so that they receive training to know how to integrate the different types of technology into their lessons and make learning more engaging for students. As we know that student gravitates to technology and we are living in 21st century. Attending these workshops teachers are able to know more about each technology such as the usage, programs and others. They are able to monitor the technology by themselves and by doing so they are able to carry out the lesson effectively and stimulate children learning. One implication for policy makers is that in order for the teachers to integrate the technology in the classroom to meet the need of his students, firstly you should provide or equipped the schools with the necessary technology. Without these, teachers will unable to do so, which he or she wants to; so that her students can grasp the concepts well. For the school to be equipped policy makers should also develop an infrastructure to  place the technologies. Provide the necessary security and to eliminate outdated hardware and software and replace them with up to date as the years are passing by. â€Å"When technology integration in the classroom is seamless and thoughtful, students not only become more engaged, the y begin to take more control over their own learning†. (Hertz 2014). Technology integration is the use of technology in the classroom that helps to carry out learning concepts and to manage the class, such technology are computers, overhead projectors, digital cameras, internet, tape recorders, and CD-ROMs. Digital camera is a great application in the classroom as it allows collecting and documenting exciting events in the environment. Integrating digital camera properly can help to link lessons to student’s lives. For example class letter, development of stories and community based research. Cameras can be share between classes and capture images quickly and easily, in which pictures provide important context for children learning experience. Images that are culturally relevant can be a very powerful strategy for students to learn about their community. For example teaching about vocabulary, teachers can send students outdoor with the digital camera to take pictures of events, objects or actions that represent the vocabulary that was discussed . Students can be asked to write sentences or paragraph highlighting new vocabulary. Which is a very excited way for students to increase their vocabulary and become better readers; and teachers could give students the opportunity to take pictures of events or actions that reflect in a story that was read to them, downloading pictures from the computer then allowed children to write a sentence or paragraph about each picture. Having students to take pictures of the story event or action will help them to relate what they reading to their own lives in their community. Digital camera can be used to do storytelling which produces narrated short films using music, photos and voices. The grade 3 lesson â€Å"who are the people in my community†, students and teachers can take a walk within the community with the camera and take pictures of community helpers and write sentences about each role within the community. The teacher and students can produce their story by downloading the pictures on the computer using programs such as Photo-Story, Windows Movie Maker, Powe rPoint, that include narration for each. The tape recorder and boom box can be used to engage student and help save time. One activity for the whole class is teachers can use a student to  become the classroom DJ. Using a microphone, the student announces the topic of the day’s lesson. With a book in hand students can read along with their teacher during reading time. Students can even listen to a recording of their teacher who record the book tape before. The boom box can be used to create electronic portfolio that showcase student’s best work and the learning progress during a time period. By doing this teachers can record the students reading or thinking process when solving a problem, a video clip of his or her oral presentation and a CD with the child digital story. The tape recorder can be used to record student’s reading of a text at regular intervals which is assessed at each interval and strategies plan to improve the reading fluency. The overhead projector is a display system that is used to present images, videos, texts to students. It helps to carry out concepts and for students to grasp concepts by which it stimulates learning by watching videos, interactive games and retrieving texts which aid in the development of different learning styles such as audio and visual learners. The teacher faces the students while the notes that are prepared previously revealed. The lesson becomes engaging and students are attentive or focus and not only that but the teacher becomes more efficient by sharing and creating reusable work. . An example of how teachers can make the projector a part of her lesson is if a teacher is trying to bring across the lesson of the topic family to a grade two class, students will watch a video of the family then have a discussion with the teacher, from the video students will define the term family in their own words. Students will use family related terms seen in the video to write at least five sentences. The family related terms are like: grandmother, brother and sister.

Advertisements Based on Fear Mongering Essay Example | Topics and Well Written Essays - 1500 words

Advertisements Based on Fear Mongering - Essay Example Recently advertisers have also started using ‘fear’ for selling products. Fear is an emotion that led people to make emotional choices. For instance, disinfectant advertisements showing the harmful effects bacteria may cause to humans (Tyagi & Kumar, 2004). The fear phenomenon works wonders. People get afraid of some things, or conditions get easily directed to buy the advertised products instead of getting inspired by the qualities only. Such advertising is also known as ‘shockvertising’ (Wells et al., 2011). On the other hand, the other method of advertising is by using ‘flattery’. Sometimes advertisers flatter the viewers by appreciating their choices, thoughts and notions on particular matters and then introduce the products that complement the viewers and provoke them for buying the advertised products (Armstrong, 2010). Either fear or flattery, both has found to be very effective depending on the type of the product and theme of the advert isement. In order to present the products or services to the audiences the advertisers select a suitable theme and based on it a narrative is written. The advertisement is filmed by using techniques of mise-en-scene, sound and editing to focus on highlighting the product feature to appeal maximum customers and meet the ultimate goal that is to raise the sales of the product. In this paper the Coca-Cola recent advertisement ‘Holidays are Coming’ will be analyzed based on the techniques (mise en scene, sound, editing and narrative) used in the advertisement (Coca-Cola Company, 2014). Coca-Cola rejoiced its customers by launching its classic ‘Holidays are Coming’ TV advertisement in order to celebrate Christmas (Coca Cola, 2014). The advertisement shows how seeing the huge sparkling Coca-Cola truck on the streets of their towns excites people. The commercial created hype for people of all ages including children, youth and adults as they would be a part of the campaign  when the truck would come to their towns and cities. The marketing director of Coca-Cola (UK) Zoe Howorth described the advertisement strategy as, â€Å"Coca-Cola has been spreading happiness in people on the Christmas event since long through its vibrant campaigns and Holidays are coming to the advertisement.

Political science - Essay Example The Supreme Court is a political institution like the other branches of the government such as the executive thus cannot be relied upon to make decisions on the original intention of the bill of rights. Supreme Court decisions and interpretation of the constitution is not always wrong, but the political influences experienced results to an opinion that reflects the current political tide (Garry 30). There is no explicit wording in the constitution or bill of rights that applies on to the federal government. The Constitution applies universally to all citizens and institutions in the whole nation and so do the bill of rights. The constitution and the bill of rights are thus inseparable and apply universally to the federal government, state or local authority governments. Article VI, Section 2 of the constitution is clear on the intention of those who framed the constitution since it states that ‘the constitution shall be Supreme law of land, and judges in every state shall be bound by the constitution’. Since the constitution framers implied that the judges in every state must obey the laws regardless of any contradictory state laws, it is clear that the intention was to limit the powers of both levels of government and protect the rights of all citizens in the country (Garry 67). From the ten amendments, it is only the first amendment that states that ‘Congress shall make not law’, but none of the other articles Congress shall not make such laws. It is clear from the other nine amendments that this are constitutional general statements that protect the rights of all citizens against excessive powers of federal, local and state governments. The first amendment was worded differently due to the prevailing political units and inhabitants in every state since most states were bound by religion and origin (Garry 123). The bill of rights does not intend to restrict government powers since historically there was no federal militia

Population Growth and Its Effect on Global Warming Research Paper

Population Growth and Its Effect on Global Warming - Research Paper Example , this brief essay will attempt to briefly analyze this monolithic problem in terms of the exponential growth in human population that has been evidenced over the past 200 years. Furthermore, a determination will be sought to be made with regards to the question of whether human action or natural causes best explain the climate fluctuations that planet earth has recently been chronicling. Lastly, as a function of the previous points of discussion and analysis, the author will attempt to proscribe a reasonable and performable set of steps and solutions which both the scientific community and the world at large could and should seek to employ as a function of ameliorating the stress on planet earth and the issues at hand. Furthermore, as a means of bringing such an understanding about, the analysis will also rely upon relevant scientific publications on the topic as well as verifiable statistics and charts concerning overall levels of climate change and corresponding increases in CO2 e missions by humans over the past several decades. However, noting the global climate change is an issue is not, in and of itself sufficient. As such, the analysis will also consider the rapidly increasing demand that fossil fuels have been projected to assume over the next several decades and posit a potential alternative to further environmental degredation at the hands of seemingly ever expanding human populations. Firstly, there is the point of view that strongly believes that the swings in climate change are the direct result of the presence of high amounts of human CO2 in the atmosphere that is causing a greenhouse effect on the planet and thereby causing world temperatures to rise. Prima fascia of this argument is the belief that human CO2 emissions are responsible for the changes to the global climate. It follows therefore that those which ascribe to this point of view are the most vehement that drastic and immediate changes to the manner in which human beings interact

It is important for internal and external stakeholders to know the organization reality in detailed fashion. To get the detailed information there is no substitute of accounting. It indicates that accounting does communicate reality to the stakeholders. Financial communication is the most important factor on the basis of which investment related decisions are being made. Investors invest their moneys on the basis of proper information. That information is being communicated with the help of accounting. According to the framework of Burchell, if uncertainties of

The Policies of Alexander Hamilton and Andrew Jackson Essay

The Policies of Alexander Hamilton and Andrew Jackson - Essay Example He also has a high regard towards the upper-class and educated men as the fittest to become the country’s leaders. Opposing the political views of Hamilton is Jackson’s democratic-republicanism. He stressed out the ordinary people’s right to vote and the first president to represent all Americans, regardless of their social standing (â€Å"The Presidency†). He is known to be Hamilton’s critic who contradicts federalism ideals. He regarded Hamilton’s views as elitist and idealistic. Relationship to Modern America Today, the American Federal government is a combination of two political views. It takes Hamilton’s view on the independence of government branches and Jackson’s idealism on suffrage. States also are given freedom provided that they also follow the national law. In other words, today’s politics resemble both political views. First, the elitist perspective of Hamilton is still surviving, although discouraged by mod ern thought. Many of the politicians today are with high educational background and came from influential families. Second, Jefferson’s state independence is practiced. State leaders are given the freedom to revise existing laws or to make laws not found with the rest of the states (e.g. legal drinking age). Economic Views By the end of the American Revolution, the country has to face a tremendous economic problem. There is an estimated $54 million debt of the United States while it only has barely half of the amount as their asset (â€Å"Alexander Hamilton’s†). Clearly, there is a huge deficit in the country’s economic budget. To address this problem, Alexander Hamilton was given the task to regulate all forms of economic activities until it stabilizes. As young as he was at that time, he regarded taxation and debt management as a two-way street to economic stability. He proposed that all states should be imposed by appropriate taxes for debt payment. Al though states that are already debt-free at that time resisted against this proposal, it is still pursued and became successful. The next move by Hamilton was to establish the Bank of the United States as â€Å"modeled from the Bank of England† (â€Å"Alexander Hamilton’s†) to take care of the collected taxes. While concerned with the nation’s debt payment, unlike Hamilton, Jackson disagrees with imposing taxes on states and became an advocate of the Laissez-Faire economy. This means to say that states are free to make international economic relations and other local economic activities without the imposition of taxes or the intervention of the national government (Ambrose and Martin 33). Despite the success of Hamilton's implementation of taxes and debt management, Jackson believes that an economy is better off without the presence of both. Since his younger years, Jackson hated debt in general, more so with national debt (Smith).

Summary, Plot, Moral Values, Themes the Call of the Wild Essay Example for Free

Summary, Plot, Moral Values, Themes the Call of the Wild Essay Summary: Buck, the lead character, is a much loved and pampered dog living a comfortable life on a ranch under the loving care of his owner, a wealthy judge who makes his pet want for nothing. Then one day, Bucks life takes a dramatic turn when hes sold off by an unscrupulous servant to pay a debt. He travels in a cage for the first time and is sold in Alaska, where dog-sleds are the primary mode of transportation. Buck has to quickly adapt to his new life as a sled dog and learn how to survive in a dog-eat-dog world where the competition is tough and often deadly. The basic comforts he had hitherto taken for granted, namely abundant food and warm shelter, are replaced by the bare necessities for survival which have to be fought for tooth and claw. Buck learns quickly, his physique and natural intelligence standing him in good stead, all the while improving as a sled dog and ultimately deposing the pack leader, his arch enemy: Spitz. His life changes sharply yet again, as he is sold off to Hal and his wife, people who know nothing about sledding or caring for animals till at last he is rescued by a kind and loving man, his last master: John Thornton. At last Buck finds a master who loves him besides caring for or pampering him. However this happiness is not built to last, his master is murdered by the vicious Yee-Hats, a tribe of brutal savages. In the midst of his anguish, Buck has to find his true self, he has to listen to the Call of the Wild and to answer it to go leaping towards his destiny Get this e-book now at a very low price.

Valid until Sep 22, 2012 Social/Historical context: The book was published in 1903, the time of the gold rushes and adventures in vast, unexplored tracts of land. A time before the full use of machinery and sophisticated technology, when often, dog sleds and carts were the only means of communication in the wilderness. Londons masterpiece, as it is often hailed to be, explores the heart of those yet-primitive societies on the edges of civilization, through the minds of their beasts. Writing Style: The book is written as a third-person narrative, continually following the central character and from the point of view of the central character. The language is extremely simple and lucid, and combined with a gripping plot, the book is easy to follow and hence suited for younger as well as seasoned readers. London has explored society from a dogs perspective. However the deeper, darker messages of unbound greed, ambition and ultimately the necessity of adaptability to change are easy to spot. There is an innocence in the way the author has attempted to capture the scene from a dogs point of view, this adds to the simple charm of the book. My Thoughts: One of my early classics, I read this for the first time when I was 9 and I loved it because I loved animals as all children of that age do. Now, when I reminisce about it I relate, with an adult mind, to the other themes in the book. I cannot help but wonder at the complexity of the layers, so deep yet so simply structured. A timeless tale for all and sundry.

Purpose Of Compaction: Types Of Compaction

Purpose Of Compaction: Types Of Compaction Soil compaction is one of the most critical components in the construction of highway embankments, earth dams, foundations and many other engineering structure. Soil must be compacted to their unit weights, increase the strength characteristic which increase the bearing capacity of foundations constructed over them. Soil is compacted by removing air and water from its pore space. Compaction is a change in soil structure, not just an increase in soil density. Healthy soils have a diversity of pore sizes, while compacted soils have mostly small pores. In general, Soil compaction is defined as the method of mechanically increasing the density of soil. In construction, this is a significant part of the building process. Almost all types of building sites and construction projects utilize mechanical compaction techniques. During the compaction process soil partials are pushed closer together. This reduces the size of pores, the continuity of pores, and the size and stability of aggregates. Only under severe compaction will aggregates break down.This soil density chart shows properly compacted soil. Purpose of soil Compaction: The principal reason for compacting soil is to reduce subsequent settlement under working loads. Also in a construction material, the significant engineering properties of soil are its shear strength, its compressibility, and its permeability. Compaction of the soil generally increases its shear strength, decreases its compressibility, and decreases its permeability. in addition, compaction reduces the voids ratio making it more difficult for water to flow through soil. This is important if the soil is being used to retain water such as would be required for an earth dams. So we conclude that there are four reasons to compact the soil: Increase load-bearing capacity. Prevent soil settlement. Provides stability . Reduce water seepage, swilling and construction. Poor compaction can lead to unwanted results. Figure: result of poor compaction Types of compaction: There are four types of compaction that are commonly used on soil and/or asphalt: Vibration Impact Kneading Pressure Each of these types is carried out using one of two types of forces: static or vibratory. Static force relies on the weight of a machine to apply downward pressure on soil, thus compressing the soil particles. Adding weights to, or removing them from, the compaction machine can adjust the amount of pressure. Although effective, static compaction is best suited for the upper soil layers. The types of compaction that fall under static are kneading and pressure.Padfeet on a Caterpillar CP563 Vibratory force, on the other hand, uses mechanically driven force to apply downward pressure in addition to the weight of a machine. The mechanically driven force is an applied vibratory force that rotates the eccentric weight of a piston and spring combination. Compactors achieve compaction through the use of delivering rapid blows, or impacts, to the surface. This is effective in that it not only compacts the top layers, but the deeper layers as well. With vibration, the particles are set in motion and moved closer together to form a high density Compaction soil types: Different types of compaction are best suited for different soil types and conditions. This is because of the underlying density and moisture that different soil types are able to retain. Soil types are classified in three soil groups, with consideration to grain sizes. These types are: Cohesive Granular Cohesive and granular Cohesive In cohesive soils, such as clay, the particles contain characteristics that make them easily stick together so compaction can be achieved by high impact, which forces the air out of the particles, pushing them together. Granular Granular soils include sand, gravel, and other particles that typically range in size from 0.003 to 0.08 inches (0.008 to 0.2 cm). Because granular soils have good water-draining properties, they are able to obtain high density when fully dry or saturated. Granular is best compacted by shaking or vibrating the particles. Any type of vibratory equipment is best suited for this type. Depending on the type of granular soil, different degrees of vibration are required. Granular and Cohesive Often, soils are a mixture of both granular and cohesive, requiring more precise compaction equipment. Equipment should be chosen on the basis of the soil in the mix that is present in the highest percentage. Some materials, such as asphalt, require both vibration and static pressure to be compacted effectively. Machinery uses frequency and amplitude to apply a force for compaction. Frequency is the measure of the speed of the eccentric shaft rotation, or of the jumping of the machine, quantifiable by vibrations per minute (vpm). Amplitude measures the maximum movement of a vibrating body from its axis in one direction Field Tests: It is important to know and control the soil density during compaction. Following are common field tests to determine on the spot if compaction densities are being reached. Sand Cone Test (ASTM D1556-90): A small hole (6 x 6 deep) is dug in the compacted material to be tested. The soil is removed and weighed, then dried and weighed again to determine its moisture content. A soils moisture is figured as a percentage. The specific volume of the hole is determined by filling it with calibrated dry sand from a jar and cone device. The dry weight of the soil removed is divided by the volume of sand needed to fill the hole. This gives us the density of the compacted soil in lbs per cubic foot. This density is compared to the maximum Proctor density obtained earlier, which gives us the relative density of the soil that was just compacted. Nuclear Density (ASTM D2292-91): Nuclear Density meters are a quick and fairly accurate way of determining density and moisture content. The meter uses a radioactive isotope source (Cesium 137) at the soil surface (backscatter) or from a probe placed into the soil (direct transmission). The isotope source gives off photons (usually Gamma rays) which radiate back to the maters detectors on the bottom of the unit. Dense soil absorbs more radiation than loose soil and the readings reflect overall density. Water content (ASTM D3017) can also be read, all within a few minutes. A relative Proctor density with the compaction results from the test. How the Nuclear Density test works How the Sand Cone test works FACTORS AFFECTING COMPACTION IN THE FIELD: Compaction of a particular soil is affected by following given factors: MOISTURE CONTENT Proper control of moisture content in soil is necessary for achieving desired density. Maximum density with minimum compacting effort can be achieved by compaction of soil near its OMC (Optimum Moisture Content). If natural moisture content of the soil is less than OMC, calculated amount of water should be added to soil with sprinkler attached to water tanker and mixed with soil by motor grader for uniform moisture content. When soil is too wet, it is required to be dried by aeration to reach up to OMC. Moisture content of the soil is vital to proper compaction SOIL TYPE Type of soil has a great influence on its compaction characteristics. Normally, heavy clays, clays and silt offer higher resistance to compaction where as sandy soils and coarse grained or gravelly soils are amenable for easy compaction. The coarse-grained soils yield higher densities in comparison to clays. A well-graded soil can be compacted to higher density. LAYER THICKNESS The more the thickness of layer of earth subjected to field compaction, the less the energy input per unit weight of soil and hence, less is the compaction under each pass of the roller. Suitable thickness of soil of each layer is necessary to achieve uniform thickness. Layer thickness depends upon type of soil involved and type of roller, its weight and contact pressure of its drums. Normally, 200-300 mm layer thickness is optimum in the field for achieving homogeneous compaction. CONTACT PRESSURE Contact pressure depends on the weight of the roller wheel and the contact area. In case of pneumatic roller, the tyre inflation pressure also determines the contact pressure in addition to wheel load. A higher contact pressure increases the dry density and lowers the optimum moisture content SPEED OF ROLLING Speed of rolling has a very important bearing on the roller output. The greater the speed of rolling, the more the length of embankment that can be compacted in one day. Speed was found to be a significant factor for vibratory rollers because its number of vibrations per minute is not related to its forward speed. Therefore, the slower the speed of travel, the more vibrations at a given point and lesser number of pass required to attain a given density. TYPE OF COMPACTING EQUIPMENTS A large variety of mechanical equipments is available for compaction of soil but soil type and moisture condition will often dictate the type of equipments and method of use. Some important compacting equipment are given below: 1. Light compacting equipments (Rammers/Plate compactors) 2. Smooth wheel rollers 3. Sheepsfoot rollers 4. Pneumatic tyred rollers 5. Vibratory rollers 6. Grid rollers 2003 Dynapac CC122 Tandem Vibratory Smooth Drum Roller .

It is used for support of structural entities such as building foundations, roadways, walkways, and earth retaining structures to name a few. In general, the preselected soil should have adequate strength, be relatively incompressible so that future settlement is not significant, be stable against volume change as water content or other factors vary, be durable and safe against deterioration, and possess prop Refrances: Das, Braja M.
