History and Development of Air-conditioning Research Paper

History and Development of Air-conditioning - Research Paper Example A close ancestor to the modern air conditioner units made in 1902, by an American engineer by the name of Willis Carrier. The machine at that time called "Apparatus for Treating Air" and built for the Sackett-Wilhelms Lithographing and Publishing Co. in Brooklyn, New York. Chilled coils used in machines to reduce air and lower humidity to 55%. Although the apparatus made with enough precision that the humidity level desired was adjustable. ("History of Air Conditioning") The article explains how air conditioners started becoming a commercial product as it became increasingly in use for industrial purposes. The real breakthrough achieved when Carrier had the benign dielene together with a central compressor replacing the ammonia thus reducing the size of the unit. Willis Carrier's invention came late in the 1900s, but before that, several attempts to air conditioning existed. In 180 AD, Ding Huan discovered the first ventilation system that was fan powered. The fan passed air from cold water and the air then spread in the house manually (Paventi). Later fountain water used to power the engine of the fan, thus reducing manual labor. Apart from the cooling effect of the water, the air became humid too (Paventi). In 1820 Michael Faraday, a British scientist, made a compressor that used ammonia (Paventi). Exhaustion of the toxic ammonia fumes became difficult and thus the cooling effect was unsafe. However, up to date his compressing technology is still in use.

UC Essay Prompt Essay Prompt 1: Describe the world you come from — for example, your family, community or school — and tell us how your world has shaped your dreams and aspirations. The school that I come from, Campolindo High School, is one of the best high schools in the state. We were often told to not be worried about getting what we believe to be bad grades in the harder classes that we take because getting a B or sometimes even a C is equivalent to get an A in most other high schools. We have been told throughout high school that a high standard is expected of us, like receiving high scores on standardized tests like the SAT, ACT, AP exams, the CAHSEE, and the Star tests. We are also expected to behave a certain way outside of school because it has a reputation to uphold and all of us are linked to that reputation. I think that high standard from Campolindo has transferred and been engrained in life outside of school. From this point on in my life, I will expect only the best of myself because anything less than that isn’t worth the time or the effort and it just looks bad to other people as well. I don’t have to succeed all the time in everything that I do, but I must always learn from what I fail at so the next time I attempt it, I will succeed. Campolindo High School has opened up endless possibilities for my future and I am very excited to experience them. Prompt 2: Tell us about a personal quality, talent, accomplishment, contribution or experience that is important to you. What about this quality or accomplishment makes you proud and how does it relate to the person you are? Going to Hayward La Honda Music Camp is an experience that I will never forget. The camp feels like its cut off from the rest of the world, none of the problems from my life follow me to band camp. It’s a place where I forget all of my troubles for the week that I am there, a nice escape from reality. It’s also a place to meet fun and interesting new people. The campers who go there range from entering sixth grade to graduating high school. All the different levels of musicianship come together within several bands, orchestras, and even choir. Everyone always learns something about playing better because there is always someone who is better than them at La Honda. Band camp is the best place to hear strange stories as well as the best place to get stories to tell to friends at school, because everyone loves a story that starts out with â€Å"one time at band camp†. La Honda doesn’t just teach me how to play my oboe better; it teaches me how to grow as a person. I learn about teamwork and how to communicate with others with gestures and thoughts instead of words. I have also learned about disciplining myself, holding back impulses, thinking things through before I make a decision. All of these skills that I learn at band camp will not only help me when playing with a band or orchestra, but in all areas of my life. What I learn at band camp can’t be learned in my high school band. At high school, most of the people aren’t committed to making music, they take band because it’s an easy class to get a good grade in, their parents made them take it, it looks good for college, especially if they started in sixth or seventh grade, they can screw around with their friends during rehearsal, or they need at least one year of a performing arts class in order to graduate. At La Honda, everyone is there because they want to work together to create the most beautiful music that they can possible create. La Honda isn’t just about playing music though, it’s about making friendships and learning all kinds of skills that will last throughout your life.

Urban Infrastructure in China

Urban Infrastructure in China This paper consists on of issues with public finance within the area of infrastructure. My focus is on Chinas development and how it is on the rise of becoming an economic dynamo. China is aiming to make its countrys global trade and capital flows a powerful force in worldwide management. I will be going into depth about the rapid increase in need for urban infrastructure and what China is doing to fulfill these needs. The issue of infrastructure funding has become more and more of an issue throughout the years. This paper will highlight the many advantages and issues that come with Chinas infrastructure funding. It will also further discuss the mechanisms that allow Chinas funding to flow smoothly throughout the local governments and the increase in how many citizens, administrators, and politicians are interested in increasing public participation in these public decisions (Susel, King, Feltey 1998). A. Introduction: Urban Infrastructure in China Infrastructure is the internal facilities of a country that make business activity possible, such as communication, transportation, and distribution networks, financial institutions and markets, and energy supply systems ( Businessdictionary 2017). Infrastructure, according to empirical and theoretical studies such as Agenor and Moreno Dodson (2006) and Anderson et al (2006), in Yingying Shis article, promotes growth through several channels. It has become one of the number one sources of enhancing factor productivity (2013). The public nature of infrastructure allows the government to use it as a monetary tool. However, the roles and effects infrastructure plays across countries varies extremely. The relationship the government and the private sector have is at the very center of the problem determining how to finance infrastructure. EIB PAPERS says, it is for the public policy to decide which types of infrastructure to put in place at which network size, to govern the planning and licensing activities and to set the regulatory framework, which determines inter alia the price of using the infrastructure services (EIB PAPERS). Chinas economic growth has caused the development of finance landscape to become very dynamic. With the hasty increase in the need for infrastructure Chinas biggest concern has become funding. This is affecting the welfare of the citizens, but is also persuading the progress of the society. According to Chengxin Cao and Zhirong Jerry Zhao, one of the most important reasons for the slower infrastructure growth is low government spending on infrastructure, which is caused by limited resources of urban infrastructure (2011).   Over the years, the main source of money was converted from mostly financial allocation and local taxes, to land transfer fees. This has caused China to pick up the speed on building infrastructure through their country. B. In Support of Urban Infrastructure in China China is todays number one country that is on the economic rise. It is expected to continue this for several decades. James F. Hoge Jr. states in his article A Global Power Shift in the Making that Chinas economic rise will continue if, it can manage the tremendous disruptions caused by rapid growth, such as internal migration from rural to urban areas, high levels of unemployment, massive bank debt, and pervasive corruption (2004). However, because of Chinas economic expansion it has become a major consumer of oil, metals, timbers, gas, and fish. This causing it to need more infrastructure. With new infrastructure projects put into place more citizens are becoming employed. According to M. Jae Moon, the idea of pay-for-performance has been adopted by many of the public agencies as a new means of enhancing motivation and improving organizational performance in the public sector under the performance management and recognition system (Moon 2000). With this put it place in motivates the workers in China to strive to achieve their goals with infrastructure. Jorge Martinez, Baoyun Qian, Shuilin Wang, Li Zhang, and Heng-fu Zou state, capital investment in infrastructure is the shared responsibility of the central government and sub-national governments, both levels playing equally important roles (2014). According to the World Bank (1995) in Yingying Shis article, Chinas infrastructure investment was about 6.5% of its GDP in 1993, well above the average level of 4% GDP for developing countries. By the year 2009, investment in infrastructure sectors, energy, transport and tele communications, water and sewage, etc, had reached to about 15% to 20% for the coastal provinces and municipalities (2013). Today Chinas new infrastructure consists of new expressways (one that is about two-thirds the length of the United States Interstate Highway  System), airports, railways, and rerouting its rivers. Their public sectors granted reforms gives the local governments autonomy on their own spending such as these new infrastructures being built. According to analysis by KPMG and Anne VanderMey, last year China invested $207 billion in road construction and upgrades (2013). The highway construction is an important part of Chinas efforts to create jobs, and helping transport supplies and goods from factories to ports. Many of Chinas economic goals hinge on efficient transport: The shift from rural to urban living has necessitated vast investments in transit, both in cities and the country (VanderMey 2013). With the increase in connectivity through China, they hope they will be able to tap into the immense spending potential of its growing middle class. Without China and its economic growth, the rest of the United States would not be the same. That is why it is a large asset for infrastructure to be put ahead of any other investment, because it is a necessity. The United States needs China to have more means of transportation and different paths, so that they can receive important goods. The nature of infrastructure investment, which requires large sunk costs and whose benefits in general cover a large number of people, is considered best with public provision (Shi 2013). C. Against Urban Infrastructure in China Chinas economy is rapidly growing and changing every single day. To keep up with the changes money must be involved. One of the main challenges still facing Chinas fiscal  system is the important local differences in fiscal resources across their sub-national governments. Regional disparities could be, to some extent, interpreted as the necessary cost to achieve other goals of economic reforms such as economic development and growth and more sub national autonomy; however, the costs of these disparities also have increased and could now  exceed the potential benefits (Martinez, Qian, Wang, Zhang, Zou 2014). It has become hard for local government to be able to finance all of Chinas expenditures (infrastructure), in fact, at the county level and central areas on the country they are in debt. The central government has tried to enforce the administration of extra-budgetary revenues and make efforts to reduce illegal fees and add-ons. Because of this, extra-budgetary income and off- budgetary income have become major sources of incomes for Chinas local governments. According to Chinas 1994 Budget Law, local governments are forbidden from borrowing in the capital market. However, given the still limited direct financing and indirect financing through intergovernmental transfers much of the actual financing of these sub-national governments spending is through borrowing (Martinez, Qian, Wang, Zhang, Zou 2014). Although borrowing money to help build infrastructure is a positive thing it is also very negative because it puts China more and more in debt each time a road or plane is built. In result, inefficient and risky projects arise that may not yield long run benefits and my not be plausible given the current and projected local economic conditions (Shi 2013). We do not see it but several of the local governments in China are in a serious money crisis. This has caused a  negative impact on the quality and quantity of basic public services for China. Many people believe that China has weak organizations of budget implementation, does not have c ontrol on  their budgets, and that the financing model that upkeeps government-led infrastructure development is not supportable D. Critique of both sides: Money for Infrastructure in China? Almost everyone in the United States can agree that China is on its way to becoming the number one largest country that everyone depends on. In fact, from 2013 to 2015 China was the worlds largest exporter. China is currently Americas biggest banker. The question is however,  should China continue to receive money to continue building infrastructure in their country. According to John Bachmann and Joe Burnett, infrastructure has opened the door to socio-economic development in China. Economic growth- facilitated in part by roads, water and power investments- has helped pull roughly 700 million people above the poverty line in the last 20 year (2012). Not only is building infrastructure allowing each country to interact with one another, but it is also helping China citizens which is a very big deal. The money that is coming from Chinas local governments is being put towards something beneficial. China has been able to succeed in infrastructure building because of its centralized po litical system. Each level is responsible for the higher level of government. So, if one level of government believes that money needs to be put towards a certain part of infrastructure, another part of the government can look and see if this would be a useful investment. The role of infrastructure changes depending on the economic conditions for instance: Infrastructure investment has shifted from accommodating to the growth of an export oriented economy to a fiscal stimulus tool in the lagging area. China has indeed been leading other developing countries in infrastructure building. Infrastructure investment  has become one of the most important pillars of Chinas growing export-oriented and investment led economy (Shi 2013). While infrastructure financing in China can be beneficial to China and other countries it can also have a negative effect. Like I discussed earlier in my paper, debt is a major issue when it comes  to infrastructure financing. China normally has received its financing from government loaning and land-transfer revenues, but as revenues reduce, risks for the local governments have risen. According to Zuo Kun, Chinas Ministry of Finance is working to promote the PPP model in infrastructure projects by identifying the respective rights, obligations, risks, and revenues of both public-and private-sector partners (2014). The government hopes with this plan that they can build beneficial partnerships with the private sector and public projects. E. Conclusion As individuals, we are all given the freedom to voice our own opinions on topics such as infrastructure financing. On this topic, I believe that China should continue to be given money to proceed with their processes on building new and improved infrastructure. If the United States wants to continue to grow economically then we must benefit from China by supporting them one hundred percent. China may have public finance issues that are occurring within their government but with the help from the PPP mode and private investments in joint ownership the government debt will hopefully begin to decrease and will help solve other financing issues. China is striving to create more and more means of infrastructure to help every nation possible and to help with this, the central government is determined to improve the urban infrastructure in any way, they see possible. I believe that for a country like China, who has built its economic growth on such low-quality equipment, is an achievement on its own. Looking towards the future, China should continue its five-year plan, Going Global Strategy. According to WWF this plan, encourages Chinese companies to invest overseas (2017). This  will help China save money and not put it to waste. I look forward to seeing China continue to grow economically helping each country in any way they can. References Bachmann, J., Burnett, J.

Charles Dickens :: GCSE English Literature Coursework

Charles Dickens (1812-1870) is one of the greatest and most popular writers in the history of literature. In his novels, Dickens combines masterly storytelling, humor, pathos, and irony with sharp social criticism and acute observation of people and places, both real and imagined. On February 7, 1812, in Portsmouth, England, Charles Dickens was born to John and Elizabeth Dickens. Charles was the second of eight children. He spent most of his childhood in London, the setting for many of his novels. He lived in a middle-classed family that, but his father was incapable of managing his own finances. Dickens started school at the age of nine, but his education was interrupted when his father was imprisoned for debt in 1824. He was then forced to work at Warren’s Blacking Factory, a shoe-polish factory, to support himself. His experiences of trying to survive in the slums of England haunted him all of his life, and he would later devote many of his books to the retelling of his experiences. Dickens was saved from this situation when his father was released from prison. From 1825 to 1827, Dickens again attended school for two years of formal schooling at Wellington House Academy in Hamstead. For the most part, however, he was self-educated. In 1827, dickens took a job as a legal clerk. By 1829, he had become a free-lance reporter at Doctor’s Commons Courts. He had become a very successful shorthand reporter of Parliamentary debates in the House of Commons and began work as a reporter for a newspaper, in 1832. During his time as a reporter he would develop his skills to write very detailed and factual-like stories. In 1833, Dickens published his first of a series of original descriptive sketches of daily life in London. By 1834, he and adopted the pseudonym â€Å"Boz.† His Sketches by Boz was published in 1836. During that year he would marry Catherine Hogarth on April 2, 1836. In 1836, Charles dickens published his first novel The Posthumous Papers of the Pickwick Club. The success of the Pickwick Papers made him famous. At the same time it influenced the publishing industry in Great Britain, being issued in an unusual form, that of inexpensive monthly installments that would run in literary magazines.

Free Companies :: Essays Papers

Free Companies In 1337 hostilities erupted between France and England that would continue, with brief times of peace, until 1453. This war, which lasted for over a century, would latter be known as The Hundred Years' War. One of the terms that originated during this war were bands of mercenaries formed in France called Free Companies. To understand Free Companies fully one must first look at the Hundred Years War for explanation. "The Hundred Years War was the last great medieval war." (http://www.cfcsc.dnd.ca/links/milhist/100.html) Not only was this war between kings, but lesser nobles too were fighting for their own interests, while they fought for their country. Looking back two centuries earlier can be seen as the true cause for this war. When Duke William of Normandy conquered England in 1066, he did so as a subject of the French King. The French speaking English Kings to follow gained more and more land from the English. But the English King still ruled two French provinces, Gascony and Guyenne. In the 14th century, the French king Philip VI demanded that the English return these provinces to the French. When Edward III denied Philip VI of this, saying that Philip's claim to the French thrown was not as strong as Edward's own right to rule both France and England, war broke out. Because the kings and nobles were not wealthy enough to maintain armies permanently, and the ancient system of raising troops through feudal obligation had, for the time being, fallen apart, the most effective armies were made up of mercenaries. The definition of mercenaries given by the Oxford American Dictionary is "professional soldiers serving a foreign country." These professional, paid troops became a popular practice through out Europe in the 14th century. Both Knights and commoners under arms were eager to take the money of anyone wishing to raise an army. The English were the first of these two countries to use this practice. Free Companies were formed by the English to fight in France.
