Project Essay The polymer will lose its high bendable strength as more water is animal units bonded together. Polyvinyl acetate is a rubbery synthetic polymer. This polymer is a component in glue. Mixing borax with polyvinyl acetate will cause it to cross-link and form slime. Cross-linking is a bond that links one polymer chain to another. (see diagram below). Borax, which is also, known as sodium borate is a non- toxic substance and has a wide-variety of uses. We need to use our knowledge of chemistry to explain the physical characteristics and chemical behavior of a particular material. Our objective in this experiment was to create a polymer ball that was both echo-friendly and nontoxic. Methods/Procedures The following items were used: -Polyvinyl alcohol -Sodium borate -Polyvinyl acetate solid -Starch During week one of our experiment we used all of the ingredients that were given to us. A 10:1 ratio between polyvinyl alcohol and sodium borate was used. We used this ratio because while conducting research, there was a similar experiment to the polymer ball and it said a 10:1 ratio was used. Ml of borax and ml of polyvinyl alcohol was poured into a mall beaker.

Ml of polyvinyl acetate was hen poured into the mixture. The mixture was stirred for 2-3 minutes. During week two we were supposed to tweak our mixture and also make our polymer ball resistant to the heat and cold because it was going to be shipped from Florida to New Mexico to Alaska. During this experiment we changed our experiment using less ingredients and less substances. The only ingredients used were the polyvinyl alcohol and the sodium borate. Ml of polyvinyl alcohol and ml of sodium borate were mixed in a mall beaker. The mixture was stirred until it started to thicken which took about 10-15 minutes. The mixture was taken out of the beaker, and rolled into a ball for about 5 minutes then put back in the beaker and let it sit for 20 minutes. After 20 minutes, the mixture became less sticky and was easier to roll into the shape of a ball. Since we were supposed to create a ball that was resistant to different climate temperatures, the polymer ball was split into two. Half of the ball would be in hot water and the other would be in ice. Results/Discussion When the Papa and sodium borate were mixed together, the mixture became very sticky and a lot of air bubbles were formed and the mixture also foamed. The mixture kook the shape of the beaker, but when it was taken out of the beaker and was left to sit on the table, the polymer would flatten out. This is called shape memory, materials that can remember their shape after a distortion occurs and can reconfigure its shape upon a stimulus. In the second week of this experiment we planned to not use starch, or polyvinyl polyvinyl acetate solid did nothing to our product. To test the polymer ball as to whether or not the ball could withstand different temperature climates. Two tests were performed. An ice bath test, and a boiling water test. One half of the ball was tinting in a beaker of ice. As soon as the polymer was placed in the beaker it started to steam and immediately it started to freeze. The p olymer also started to flatten out. When it was taken out of the ice it was very slippery and hard to grip. It was also difficult to roll into a ball. But, after it sat in room temperature it was easier to mold into a ball and still carried the bounce that a bouncy ball should have. In boiling water experiment, water was boiled in a beaker with the use of a Bunsen burner. After the water was boiling we placed the polymer ball into the water and it melted UT didnt fully dissolve in the water. There was a layer of the polymer ball floating in the water. We collected the layer and put the substance into a beaker. When the substance cooled down and was back to room temperature, the substance became very stretchy. The polymer could also be rolled back into a ball. Conclusion In conclusion, we were not able to create a polymer ball that would be able to withstand different climate changes, but were able to create the bouncy ball. The polymers we created did bounce although they were a little floppy and werent perfect spheres. The polymer stuck to all surfaces but was easy to pull off. It was moldable and easy to form. It couldnt be pulled apart or stretched, Just squished and squeezed. When the polyvinyl acetate solid was added to our first mixture it had glue like color and no changes were made to the substance. When you add borax solution to polymers like PA, it cross-links the two polymers together like a net. Depending on how much of each ingredient is mixed you can either make a mixture that is slimy or stretchy. By adding cornstarch the mixture will be able to bend and stretch the mix. Most plastics are polymers. For example PVC pipes is the continuous linking of the same molecule.

How to Write an Interesting Biography A biography is a written account of the series of events that make up a persons life. Some of those events are going to be pretty boring, so youll need to try to make your account as interesting as possible! Every student will write a biography at some point, but the level of detail and sophistication will differ. A fourth grade biography will be much different from a middle school-level biography or a high school or college-level biography. However, each biography will include the basic details. The first information you should gather in your research will include biographical details and facts. You must use a trustworthy resource to ensure that your information is accurate. Using research note cards, collect the following data, carefully recording the source for each piece of information: Including Basic Details Date and place of birth and deathFamily informationLifetime accomplishmentsMajor events of lifeEffects/impact on society, historical significance While this information is necessary to your project, these dry facts, on their own, dont really make a very good biography. Once youve found these basics, youll want to dig a little deeper. You choose a certain person because you think he or she is interesting, so you certainly dont want to burden your paper with an inventory of boring facts. Your goal is to impress your reader! Start off with great first sentence. Its a good idea to begin with a really interesting statement, a little-known fact, or really intriguing event. You should avoid starting out with a standard but boring line like: Meriwether Lewis was born in Virginia in 1774. Instead, try starting with something like this: Late one afternoon in October, 1809, Meriwether Lewis arrived at a small log cabin nestled deep in the Tennessee Mountains. By sunrise on the following day, he was dead, having suffered gunshot wounds to the head and chest. Youll have to make sure your beginning is motivating, but it should also be relevant. The next sentence or two should lead into your thesis statement, or main message of your biography. It was a tragic end to a life that had so deeply affected the course of history in the United States. Meriwether Lewis, a driven and often tormented soul, led an expedition of discovery that expanded a young nations economic potential, increased its scientific understanding, and enhanced its worldwide reputation. Now that youve created an impressive beginning, youll want to continue the flow. Find more intriguing details about the man and his work, and weave them into the composition. Examples of Interesting Details: Some people believed that Lewis and Clark would encounter elephants in the western wilderness, having misunderstood the wooly mammoth bones discovered in the United States.The expedition resulted in the discovery and description of 122 new animal species and subspecies.Lewis was a hypochondriac.His death is still an unsolved mystery, although it was ruled a suicide. You can find interesting facts by consulting diverse sources. Fill the body of your biography with material that gives insight into your subjects personality. For instance, in a biography about Meriwether Lewis, you would ask what traits or events motivated him to embark on such a monumental exercise. Questions to Consider in Your Biography: Was there something in your subjects childhood that shaped his/her personality?Was there a personality trait that drove him/her to succeed or impeded his progress?What adjectives would you use to describe him/her?What were some turning points in this life?What was his/her impact on history? Be sure to use transitional phrases and words to link your paragraphs and make your composition paragraphs flow. It is normal for good writers to re-arrange their sentences to create a better paper. The final paragraph will summarize your main points and re-assert your main claim about your subject. It should point out your main points, re-name the person youre writing about, but it should not repeat specific examples. As always, proofread your paper and check for errors. Create a bibliography and title page according to your teachers instructions. Consult a style guide for proper documentation.

The Benefits of the Education are Depended on Size Classes - Essay Example The more learning that is taken on within their stride, the better they become. This is a sign of learning something new everyday at a very little cost which is all the more welcome. It is a fact that small size classes are deemed as very healthy for the sake of any society in the world and there are no parallels as far as this understanding is reached upon. The society takes the benefits in such a situation and nearly everyone who is a part of it will benefit in one way or the other. When one focuses on how Japanese educational system works, one wonders if they follow the same pattern. On a closer look, there is research that supports the basis of large size classes within Japan which should speak what has been written earlier in terms of the disadvantages. Yet this is not true because Japanese are known to be more resilient in terms of their educational settings, which allows proper emphasis on education on the part of the students. The students are made to work in groups, which de dicates equal time and energies towards studies and thus no one feels left out of the related equation. It makes their tasks easier and the learning is immense under such scenarios (Tyre, 2011). As compared to Americans, Japanese are more focused and involve their own selves within education so that they can get the best results out of what they have studied for their long term success. In the end, it would be fair to state that both the STAR and SAGE studies have accounted for a number of benefits for the students from a global perspective. These benefits follow the dictum of providing health and happiness for the society as a whole. The students have taken on the advantages which is actually a good point if seen within the... This paper approves that the discussion centers on the aspect of the society, small size classes are able to support the poor students much better in terms of their socioeconomic living. It allows them to learn more and gain assistance from the educational domains because high costs of living are coming about with the passage of time. The more learning that is taken on within their stride, the better they become. This is a sign of learning something new everyday at a very little cost which is all the more welcome. It is a fact that small size classes are deemed as very healthy for the sake of any society in the world and there are no parallels as far as this understanding is reached upon. The society takes the benefits in such a situation and nearly everyone who is a part of it will benefit in one way or the other This essay makes a conclusion that it would be fair to state that both the STAR and SAGE studies have accounted for a number of benefits for the students from a global perspective. These benefits follow the dictum of providing health and happiness for the society as a whole. The students have taken on the advantages which is actually a good point if seen within the correct settings. Since the Japanese students are seen as helping one another, this point has become even stronger in terms of its collaboration debate. These are some of the more important details that have come about as far as knowing how size classes have affected the students in different parts of the world. What remains to be seen is which model is being followed to bring about prosperity in terms of education worldwide.

Evolve - Article Example The worst decision that a company can make is to the same. However, maintaining the current business framework might have short-term benefits as it may help the company survive in the foreseen future. This however fails to generate the competitive advantage that is important for the long- term survival of the business. The bottom line is that companies need to change to ensure their prolonged survival through the recession. Companies are going through the worst recession in history and the only way they can survive through it is by changing the methods they use to carry out business. This also enables the company to gain a competitive advantage over its rivals in the market. Forces of globalization, increasing competition, changing customer needs and scarcity of resources have been mounting increasing pressure on businesses in the modern world to evolve (Pentilla, 2009). Generally, introducing and managing change in companies can be difficult. Therefore, companies need to be equipped with the necessary tools and adopt appropriate mechanisms effectively implement the change and adopt a new style of doing things. There are seven steps that can be followed by companies in the process to change their game. The first step is getting comfortable with the chaos in the current business environment. The forces of globalization and technological advancements lead to regular economic turbulence. This step begins by accepting that there is need to change the way things are done within an entity. It is important to note that there are continuous disruptions between periods of prosperity and economic downturns and companies cannot forecast when they are bound to occur. It is therefore important for companies to keep up with market trends and make relevant changes in their business model (Pentilla, 2009). The second step in effectively changing a companyÃ¢â¬â¢s game is by reevaluating the customersÃ¢â¬â¢ values. The economic recession has led to a drastic change in the

Information and Communication Technologies in Virgin Atlantic - Essay Example With emphasis on the airline industry, the emergence of internet and the subsequent development of extranets and intranets forced airlines to rethink their strategies on technological innovation and enhance their competitiveness in their market niche. The internet has proved a source of opportunity to tackle distribution costs and reengineer the structure of the airline industry (Alamdari and Mason, 2006:123). These technological innovations seek to monitor a wide range of business processes in the airlines, as well as identifying ways of improving these processes. This report examines the implementation of the online ticket booking by Virgin Atlantic Airways to achieve cost reduction and competitive advantage objectives. The report works on the assumption that the previous booking systems had flaws in efficiency and effectiveness, thus the company sort to redesign the booking process to attain some competitive edge against its competitors and increase its effectiveness and efficienc y in general (Olugbenga, 2006). Virgin Atlantic Airways Limited Virgin Atlantic Airways Limited, famously as simply Virgin Atlantic, is a British airline headquartered in West Sussex, England. The airline, founded in 1984, has become the second largest carrier in Britain serving the major cities in the world. Currently based in Manchester airport, Heathrow airports, and Gatwick in London, the airline operates long-haul services to more than thirty destinations worldwide, as far apart as Shanghai and Las Vegas. Virgin Atlantic enjoys huge popularity, receiving top business, trade, and consumer awards worldwide. The airline has credit for pioneering a range of innovations and setting new service standards, with its competitors seeking to follow the same... This essay stresses that for Virgin Atlantic to achieve competitive advantage in the airline industry, it needs to develop and implement innovative strategies to improve the sale of ticket, as this forms the primary source of income. The company may integrate ICT tools to achieve this, including developing an efficient booking system incorporated into the official website of the company. This paper makes a conclusion that ICT may support all business functions, thus integral in the efficient operation of the entire travel industry. ICT provides tools for searching for profitable and meaningful niche market segments and identify value added components for the services and products, as well as differentiate these services and products through special media to market segments. Flexibility and cost effectiveness are among the products of ICT in this process, as they are integral in cost efficiency maximization and cost reduction. The impact of ICT on the airlines industry is persuasive, as information forms the core foundation of the daily operations and the strategic management of organizations. This is evident from the implementation of Virgin Atlantic online ticket booking. The online service has significantly improved the services of the company in all levels of management. Subsequently, there has improvement in tickets sales, with increased efficiency and effectiven ess. At the strategic level, airlines must continuously assess all the external elements of the environment, as well as customersÃ¢â¬â¢ needs and competitors, and subsequently adapt to them to enhance their competitiveness

Social Change In Pakistan Pakistan enters the second decade of the 21st Century as a majority middle class society, indicating an increasing social and economic mobilityÃ Ã and therefore demand for new services and for global relationships. This process of social change from Feudal to Civil society is fraught with complications creating institutional vacuum that distorts the social change process and makes the change slow and reducing societys competitive advantage vis-Ã -vis other societies. One of the major impact is that about 60% of the middle class comprises of low income households who earn between Rs.5000 (US$60) and Rs.25000 (US$300). The low income households are highly vulnerable to slipping below the poverty line, have little or no citizenship rights and political voice and depend on informal sector for housing, employment, finance, transportation and social services. The second impact is the massive environmental degradation and pollution due to unregulated production and exploitation of natural resources. Now with more than 70% of the population below 30 years of ages, and the ever increasing demand for services and low level of energy production and infrastructure development, Pakistani society faces a crisis of competitiveness to benefit from the social change process. Also Pakistan has been carved out of the Indian sub continent where the Central Asian Tribal society and the Indian Caste based society meet. On right bank of the Indus River, especially in the North Western Frontier Province (NWFP) and the upper reaches of Balochistan, bordering with Afghanistan, the society has a strong tribal nature. Of the 9% of Pakistans 168.8 million persons living on the right bank, 23% are middle class and the urban proportion is 20%. On the left bank of the Indus River where the caste societal structure is crumbling, 64% of the population is middle class and the urban proportion is near to 40%. The violence accompanying the societal change evident in 16th century Britain, and in 18th and 19th century Europe and America that ushered in a constitutional government and abolished slavery and fiefdoms, is now taking place on the right bank of Indus River. One reason for the delayed change is the existence of the tribal institutions that is strongly conservative i n nature, values survival, and has the capacity to maintain subsistence economy based on natural resources and wars to capture neighboring resources. The closing in of the borders is forcing the tribal society to change, but there is a strong resistance given the foreign aid it receives. The Caste based society; mainly feudal in nature has undergone considerable change since British colonization of the Indian subcontinent triggered the change from Feudal to Civil society in the Mid-Nineteenth century. The British were able to trigger the change because the Civil society structure they brought was more advancedÃ Ã than the Feudal, and it was in an advanced stage of development in BritainÃ Ã . The Colonization process started a process of capture of resources (restraining the locals from its use), its massive conversion into capital, and its transfer to Britain for its Industrial development. This process was facilitated by technological innovation and marginalized the local communities directly dependent on them. To help the British in this process they created a cadre of people i.e. educated them, gave them political and administrative powers and enabled them to become economic agents. The English Speaking elite that emerged through a century of British rule continue to play key role in the transfer of resources from Pakistan to global market at the cost of local population. These elite hold key position in Government, academia, businesses and military. They create nexus to marginalize other sections of the society from developing and partner with external forces to exploit the countrys human, financial and natural resources. They influence government policies and prevent low income groups from legitimizing their social, economic and political assets. And therefore, restricts the society from developing new services and institutions and keeps the low income dependent on mafia for services. This process like virus corrupts all new reforms and innovations and kills them before they can institutionalize. To maintain the status quo, they capture benefits from development projects and malign citizen organizations from bringing about social change. After the Aryans invaded the subcontinent and pushed the Dravidian society to retreat, they established the Caste structure that gave the highest position to the priest class, secondary positions to warriors and traders, and relegated the non-Aryan to a position of slavery and outcasts. This society grew and developed and consolidated the feudal mindset. Muslim invasion of the subcontinent created a historical schism in the existing society and divided it into two nations. Being invaders and rulers, the Muslims could not be relegated to the slave status and at the same time the Muslims coming from a tribal society could not enforce a new structure on the existing more advanced social structure. During the Moghul rule, attempts were made to bring the nations together but to no avail. As the British opened doors to social and economic mobility, the secondary castes were quick in entering the elite circle, while the Muslims because of their elite nature alienated themselves from the dev elopment process and even opposed the process. Within the Muslims developed orthodoxy and conservative forced entrenched themselves as leaders. During the British rule, the caste system began to weaken but the Hindu-Muslim schism widened. On the eve of partition, Bengal and Punjab were divided and mass migration took place. The violence that took place during Partition and the forceful capture of Muslim states and part of Kashmir further heightened the Hindu-Muslim divide. Governance in Pakistans therefore developed as a reaction to Indian hostility and gave legitimacy and support to Conservative rule in Pakistan. In Pakistan, conservative forces created a nexus between Pakistans Muslim identity and security issue to oppose liberalizing civil society. With the setting in of the Afghan War, Pakistani conservatives received massive support that went into strengthening conservative elements and strengthening sectarian differences. The conservative elements weakened the governance structure through creation of sectarian politics, support to militancy and suppressing all other forms of political and cultural forums. They marked development as threat to Muslim identity and supported violent means to distort development, especially education, population planning and political participation. The conservatives saw the educated and emancipated young women aggressively seeking social and economic freedom and creating new aspirations, connections and symbols of expressions as a major threat, and have launched a movement to contain and regulate the emerging new woman. The backlash has been in the name of r eligion and to maintain family honor and social values. The conservatives have put up all sort of hurdles to block womens mobility, education, employment, freedom of expression (especially public appearance) and decision making. The reactions range from domestic tensions to honor killings and to preventing new women from voting and participating in political activities. Conservative forces at all levels have tried to keep the women domesticated and out of public realm to the extent of engaging in terrorism and creating human insecurity. The new women, not to be contained are sacrificing her life, honor and property to realize the new found dreams and freedom. Her greatest assistance comes from Civil societies in more advanced stage of development, and presently with more than 70% of the population below 30 years of age in Pakistan, she is poised to overcome the conservative forces with the help of foreign institutions to establish Civil society in Pakistan. In Punjab, after Independence, the immigrant Muslims settled in cities and small towns and today forms the backbone of the middle class. Even though large number of migrants was from rural areas or carried a Feudal mindset, but the migration changed them and they were forced to accept a middle class lifestyle. The Punjabis therefore participated in the market based process and took an edge given the historical discrimination facing other communities. The lower castes because of the historical discriminations began entry as the agricultural revolution mechanization, financing of agricultural inputs, land reforms, road and communication development, etc forced the feudal to release stranglehold. Coupled with Industrial production and development of urban services, agricultural revolution also set into motion rural to urban migration and the centralization of political power in cities. The middle class started developing in cities, but with Feudal order sustaining the values and mindset, the new middle class remained Feudal. The change process manifested itself in the political agenda of the seventies and in the Pakistani constitution of 1973 that recognized the people as citizens with rights and stimulated the growth of working class. It tried to decimate the edge enjoyed by the elite through nationalization and encouraging the peasants to participate in the emerging construction, transportation and communication industries. Subsequently, the low income group or working class earning a monthly household income below Rs.25,000 (US$300) and above the national poverty line of Rs.5000 (US$60) emerged as force. In addition to new migration to urban areas, the low income group also comprises of a middle class in rural areas. This group even today however has little or no access to formal sector services and citizenship rights. Consequently, they acquire these services housing, finance, transport, employment, etc. through informal sector and collaborate with mafia and interest groups to access citizenship rights and seek protection from law enforcing agencies. The low income households over time has improved its income and status with the help of informal sector and in the process strengthened the mafia and created new interest groups transporters association, informal money lenders, land mafia and land grabbers, etc. The low income households are estimated to be more than 60% in Karachi, Pakistans biggest city and in higher proportions in other urban and rural settlements. These households are most vulnerable to edging below the poverty line because of dependence on a single earner who is susceptible to health risks, human rights violations and accidents. Conclusions Summarily, the social change in Pakistan from a tribal and caste based society to Civil society is reflected in the rise of the low income groups. And this most obvious in the left bank of River Indus where rural and urban middle class are in majority. The new women are leading the social change process at a very high cost. The process however is not complete and fraught with violence. In the process of change, though middle class are in majority and increasing in number but their aspirations and demands are not finding a political expression. Three complications in the social change process have created an institutional vacuumÃ Ã : As a result of the complications in the social change process, development remains small and scattered. Big development projects marginalize the target groups, lead to elite capture of development benefits and destruction of public goods and formation of duplicate institutions. Small pilots develop into models but fail to scale up. Institutional vacuum maintains the demand for social mobilization, awareness raising and training, making development inefficient and unsustainable.

Who can turn the world on with her smile? One person stands out. A TV legend and an American icon: Mary Tyler Moore. Mary was born in Flatbush on December 29, 1973 to Irish-Catholic parents. Mary's family was neither rich nor poor. As a child, she attended St. Rose de Lima Parochial School. Her family moved to Los Angeles when she was only ten years old. When she became older, she became a popular actress. Through the years, Mary Tyler Moore has remained as popular as ever. With recent movies such as "Flirting With Disaster" and "Payback". But it wasn't always so easy for her. She started out as the leggy secretary, Sam on "Richard Diamond, Private Detective" in 1957, where you could only see her legs. In 1961, Mary got her biggest break yet, playing Laura Petrie, the wife of Rob on "The Dick Van Dyke Show". Mary played her part well for the next six years. During this time, she was awarded two Emmy's. In 1966, the show was taken off and Mary was left without a job. In 1967, Mary went on to play the part of Miss Dorothy in the Oscar winning, "Thoroughly Modern Millie". She played along side Julie Andrews and Carol Channing. In a survey taken by 97 people who had seen the movie, "Thoroughly Modern Millie" ranked a 7.7 out of on the rating scale, where 10 is the highest and 1 is the lowest. The number 10 received the highest number of votes (29). Through the years, Mary appeared in other movies, which did little for her career. Then, in 1969, she appeared with Dick Van Dyke in a special "How To Succeed in the 70's Without Really Trying" which appeared on CBS on April 13, 1969. It was this show that rekindled the network's interest in Mary Tyler Moore. CBS is reported to have said, "My God, we've discovered a star". CBS wanted Mary for a series. At the time, they felt that they needed to explain to the audience why a 30 year old woman had not been married. In a way, it demonstrated how limited the public's thinking was at the time, with respect to women. At first, the studio suggested a divorcee. Mary loved the idea, but the network soon decided that the viewing audience would think that Mary had divorced Dick Van Dyke. At first it was so frustrating to executives that they considered giving up on the series completely. On January 10, 1970,... ...eople will say "Can you believe people used to eat animals?". Mary Tyler Moore recently wrote her autobiography, which is entitled, "After All". Her biography proves that Mary Tyler Moore and Mary Richards are not much alike. She breaks new ground when she talks about her struggle with drugs and the pain of trying to help her brother commit suicide. Mary's latest feature film, "Flirting With Disaster", starring Ben Stiller and Patricia Arquette, shows a new side of Mary. The film teeters on the edge for most viewers who are used to the Ã¢â¬ËMary Richards' side of Mary Tyler Moore. Ms. Moore, on the other hand, thinks otherwise. "The characters are married adults and there's nothing actually explicitly shown. It's always over the back of the head and nothing is seen." After bit parts and lead roles, Mary Tyler Moore shows that she has had her share of ups and downs. Her production company, "Mary Tyler Moore", has produced many popular television sitcoms, and today, Mary is one of the wealthiest women in show business. In 1996 Mary was crowned Queen of Brooklyn, showing that she truly did "Make It After All"
