F. Scott Fitzgerald - A Timeless Writer Who Was a Man of His Time essays

F. Scott Fitzgerald - A Timeless Writer Who Was a Man of His Time essays F. Scott Fitzgerald is best known today as the author of the classic novel The Great Gatsby. The novel tells the story of Jay Gatsby, a poor and obscure Midwesterner who makes his fortune as a bootlegger to win the heart of his childhood sweetheart. One character says of Gatsby that he made himself up, in other words, that through creating a false personal mythology, by wearing fancy clothes, and buying fancy houses, Gatsby unsuccessfully tried to create a new identity for himself. The same could have been said of his creator, although unlike Gatsby, Fitzgerald had a far more ironic view of the world as a writer. He ironically chronicled Ivy League and elite Long Island society observed with wonder by the narrator of Fitzgeralds greatest book. Fitzgerald was born in the American heartland, in St. Paul Minnesota on September 24, 1896. His father Edward Fitzgerald was a failed furniture salesman and his mother Mary was an Irish immigrant. (Willet, 2006) Both were Catholic and thanks to his mothers inheritance, solidly middle-class, although it is said his father drank more at the office than he worked. The young Fitzgerald excelled as a writer at the Catholic school where he studied, but always felt somewhat out of his social element because of his mothers Irish birth when he ventured into the realms of the real St. Paul elite, such as at his local dancing school. (Martine, 1981, p.3) Fitzgerald got into Princeton but he was not particularly studious. He struggled academically. He wrote for the Princeton Triangle Club musicals, the Princeton Tiger humor magazine and the Nassau Literary Magazine. He was placed on academic probation. As he was unlikely to graduate he eventually dropped out of school to join the army. (Bruccoli, 1994) When the army stationed him near Montgomery, Alabama in 1918, Scott met and fell in love Zelda, who was later to become his wife. When he later proposed, Zelda initially rebuffed Fi...

IUPAC Atomic Weights of the Elements List

IUPAC Atomic Weights of the Elements List This is the 2013 list of atomic weights of the elements in increasing atomic number, as accepted by the IUPAC. The table is based on the Standard Atomic Weights Revised v2 (Sept 24,2013). The list includes the 2013  changes to the atomic weights of 19 elements: arsenic, beryllium, cadmium, cesium, cobalt, fluorine, gold, holmium, manganese, molybdenum, niobium, phosphorus, praseodymium, scandium,  selenium, thorium, thulium and yttrium. These values remain current until the IUPAC sees the need to revise them. Values given by the [a;b] notation highlights the range of atomic weights for the element. For these elements, the atomic weight is dependent on the physical and chemical history of the element. The interval reflects the minimum (a) and the maximum (b) values for the element.Values given in chevron brackets (e.g., Fm 257) are the mass numbers of the longest-lived isotope of elements that do not have stable nuclides. However, atomic weights are provided for Th, Pa, and U because these elements have a characteristic abundance in the earths crust. For detailed element facts, consult the  Periodic Table  for individual elements.

The effects of the 2008 financial crisis on the investment in the Gulf Research Paper - 1

The effects of the 2008 financial crisis on the investment in the Gulf area and Qatar - Research Paper Example While closely evaluating the investment activities of Gulf countries including Qatar during 2008 financial crisis and post-recession period, it seems that the global financial crisis did not affect the Gulf region’s investment sector much when compared to other regions. Recession 2008: Impact on the Arab Region The crisis affected most of the Arab region also causing a significant decline in financial markets. Despite the region’s potential economic sources like oil revenue, real estate investment, tourism, and housing, countries in the region became vulnerable to an economic slowdown albeit at a slower pace. The main reason was that the region’s economic activities did not involve productive actions which could reroute the wealth surplus into establishing strong industrial and human skill bases. Also, the region as a whole failed to absorb income and investment on a multiple basis. The results of the downturn were visible in the form of declining living standard s, increasing inequality, growing unemployment rate etc. Migrant workers were the most affected segment in almost every GCC country. The main investors in the region included but not limited to The Kuwait Investment Authority (KIA), the Abu Dhabi Investment Authority, Singapore GIC, the Saudi prince al-Waleed Bin Talal, Kuwait, and Qatar. The outcome for their investment in Corporates like Citigroup, Merrill Lynch, Barclays, and Credit Suisse was not satisfactory or even inflicted great loss on the investors. The crashes in the UK, U.S financial markets affected the Middle Eastern stock markets as well. On September 15th 2008, the Saudi Arabian stock market fell by 6.5%, Doha 7%, Kuwait 3% and Abu Dabi 4.35% (Casa Arabe). However, since the gulf region had already learned lessons from the recession of the 1980s and the oil price fall, they were prepared to confront the new downturn unlike many other developed nations. Evidently, the impacts of the 1980s’ price fall were more intense and rapid than the recent one. The bitter experiences of 1980s taught the GCC countries to respond more flexibly to the new crisis. The difference was that the strategic decisions taken recently were of long-term significance whereas the first ones involved rapid actions. Better fiscal policies and the private sectors’ less dependence on state spending also contributed to the relatively sustainable position of the region. The direct result of this strategy was that all rich GCC countries namely Qatar, Kuwait, and Saudi had sufficient overseas assets to carry out their annual programs at least for a short term. Post-Recession Scenario One of the post-recession trends in the Gulf investment sector is the boom of real estate market. When compared other sectors, investing in developed market real estate seemed secure and profitable for many Arab investors, among which Qatar held the prominent position. As Roubini reports, Qatar unlike its Emirati or Kuwaiti counterparts s ustained with lower loan growth, lower profitability and thereby weakening balance sheets (â€Å"Are there..†). The government bought â€Å"stakes in local banks, as well as property and equity holdings on the balance sheets of local banks† and the nation’s â€Å"sovereign wealth fund was among the first to return to significant foreign investment† (Roubini). In fact, the world overcame the issues of the 2008 recession, mainly led by Asian and Middle East countries. For instance, subsequent to the

RF Energy Harvesting - Literature review Example | Topics and Well Written Essays - 3000 words

RF Energy Harvesting - - Literature review Example Energy harvesting allows for recycling and harvesting of wasted ambient electromagnetic energy to cater for the energy requirements of devices suing wireless technology such as wireless personal area networks (WPANs), wireless local networks (WLANs) and Cellular networks. In RF energy harvesting, electrical power is transmitted from one location to another without the application of an artificial conductor. As such, there is a significant requirement for rectennas to be present in the circuit as they important in the harvesting of ambient RF power. The rectennas should be preconditioned for efficient energy harvesting by ensuring good performance at low incident power density, relative high rectification efficiency at wide bandwidth and arbitrary polarization. The advantage of harvesting energy using rectennas is in its ability to generate unlimited energy due to it unlimited lifetime without the need of replacement as in batteries. Furthermore, the energy generated is green and ther efore suitable or energy sustainability (Suh & Chang, 2002). The term rectenna refers to a rectifying antenna that serves to combine the functions of high efficient rectifier circuits and an antennae at microwave power transmission systems. Rectennas were developed with the aim of completing the wireless power transmission system. The purpose of the rectennas is to convert electromagnetic wave into DC power after being received. Rectennas can exists in the their simplest form where they consist of multiple receiving antennae elements that enter a low pass filter circuits that is usually terminated at certain rectifying diodes. In RF energy harvesting, a rectenna is used due to its desirable characteristics; the efficiency of energy harvesting resulting from conversion of microwave power to DC power can reach 85% and they can be designed to cater for different desirable frequencies capable of harvesting RF power that is easy to design and economical

Emperor Hadrian of Rome ordered its construction around ad 122. The wall extended 117 km from Solway Firth to the mouth of the Tyne River and was about 6 m high and about 2. 4 m wide. The wall also marked the frontier of Roman civil jurisdiction. A few sections of Hadrians Wall remain standing in present-day Great Britain. Island Holy Island, also called Lindisfarne, a small island off the coast of Northumberland, England, 5 sq km in area. Holy Island is connected with the mainland at low tide by a causeway. A monastery was established on Holy Island in 635 by Saint Aidan and a group of Celtic monks, who produced the elaborately decorated Lindisfarne Gospels. The island became the religious center of the Anglo-Saxon kingdom of Northumbria. In 1093 the monastery was reestablished by Benedictine monks from Durham, and the island has since been continuously occupied. Today, Holy Island is a bird sanctuary along with the neighboring rock islets of Farne.

How do the authors create atmosphere and tension in The Monkeys Paw Ess

How do the authors create atmosphere and tension in The Monkeys Paw and The Red Room? A ghost story is a story with intent to scare; it usually builds up tension and suspense by using a lot of intense, exaggerated words. Usually in a ghost story there is a typical dark and gloomy setting and an inhuman object almost always there is a non human force or a supernatural being in the story to give it a scare factor. Supernatural means a power above the forces of nature which implies that it is not human. In the time that the two stories were written, the belief in the supernatural was a lot different to those of today. They believed in such things as ghosts and witchcraft where as nowadays there are only some believers. This could be because they had less technology than today’s world so we have more evidence to whether they are or aren’t real The Monkey’s Paw is a story about a distant friend who has possession of a cursed shrivelled monkey’s paw that grants three wishes to each man that obtains it. Every wish comes true but little do they know that the wish that they asked for would backfire horrifically killing there only child. The Red Room is another story that was written in the 19th century. However different to The Monkey’s paw this story does not have a supernatural or inhuman power. The story is about a man that’s name is not told and his quest to stay in a supposedly haunted room but unluckily for him, the room possessed a far greater force than spirits or monsters but the very thing that eats away at a mans emotions-FEAR! The authors that wrote these stories use a lot of special techniques to make the audience scared and fearful; afterall the intent of the story is to scare people. Some o... ... they both play with your feelings and emotions. Both stories are written with the intent to scare and they do that. Also, they make you feel sad, disgusted and interested. I think that they do this by there powerful descriptions. And in which they use long and short sentences to build up the tension and atmosphere before the ending. Whilst studying the two books I have realise that to write a successful horror story you have to use all of the techniques and in my opinion the most important technique is descriptive language. When describing, you have to use powerful and meaningful words to give a clear visual picture and so the reader is reacting to the descriptions. I feel that if you have good descriptions then everything else will follow and if you draw the reader’s emotions in to the book then they will be more scared after the ending scare factor.

Avro Arrow

Avro Arrow Since the dawn of mankind, humans have always wanted to conquer the skies. After the Wright Brothers first flight, mankind has dreamed of bigger and better aircrafts. Shortly after World War ll a company named Avro Aircraft Limited was assigned the job by the Royal Canadian Air Force to build supersonic twin engine interceptor which could defend Canada against Soviet Bombers during the Cold War. With a plant in Milton, Ontario and 14 000 employees, Avro Aircraft Limited built and manufactured ones of the greatest planes in aviation history.The plane was a masterpiece; it flew at nearly mach 2 and had futuristic technologies which would match up to planes from today. The Avro Arrow program turned out to be a huge waste of the effort and money, as it was cancelled less than a year later. There can be many reasons why it was cancelled but the biggest was the immense pressure put on Diefenbaker by President Eisenhower and the United States Air Force. Other reasons could be bec ause of its huge price tag, a new emerging era of anti-aircraft technologies, or the fact that it had many little flaws in its design.Terminating the Avro Arrow program was the right and smarter thing to do by Prime Minister John Diefenbaker and his Conservative Government. The Avro Arrow was a Canadian marvel but came with a huge price tag. The program cost hundreds of millions of more than the estimated price. Originally the Royal Canadian Air Force wanted 40 aircrafts for an estimated $118 million but, the price tag for the interceptor rose from 2 million to 12, and at the same time demand for interceptors fell as the world entered the age of long-range missiles.When Prime Minister John Diefenbaker cancelled the program the price tag stood at $247 million for the aircraft and $132 million for the Iroquois engines. A total cost of $374 million for a bunch of scrap metal. Clearly the project wasn’t worth as much as they were spending. The company’s estimations were wa y off and the project turned out to cost one-eighteenth of the total national budget, which was money that the government didn’t have to spare and could have used for cheaper alternative defensive mechanisms.In the mid 50’s the world was entering a new era of anti-aircraft missile technologies and smarter missiles were being invented. As Canada was busily trying to find buyers for the Avro Arrow, the Americans were also hard at work trying to sell their BOMARC missiles. When Canada tried to sell the Arrow to the Americans, they tried to sell their BOMARC missiles to Canada. Unfortunately, Canada failed to sell the Avro Arrow to any nation. Instead the newly elected Conservatives cancelled the Avro Arrow program and decided to buy $200 million worth of BOMARC missiles.With the purchase of the missiles, the Canadians signed the NORAD (North American Air Defense) agreement which made Canada a partner in command and control when it came to attacks and threats in Canadian/A merican airspace. Also it gave RCAF a chance to learn and share secret Air Defense information with the USAF. The BOMARC missile had the same range as the Avro Arrows. The difference was that the missiles were much cheaper and were a more feasible option for the Canadian air-force and the government’s budget.The Avro Arrow had flaws in its design which didn’t let it be at one hundred percent. One of the major flaws that the Arrow had was its limited fuel capacity. It could only carry approximately 10 000 lbs of jet fuel, which meant it had very limited range. The range was such a concern that the Royal Canadian Air Force had to build many special airfields in the North because the Air-force was worried that if the Avro Arrow went on a mission, it would be able to return by refueling in the airfields because it wouldn’t have enough fuel to go and comeback on one tank full.The plane also couldn’t pass some RCAF regulations which meant spending millions more just to fix the issues. The major problems were with the avionics and fire-control of the aircrafts. There were some minor incidences as well, during flight testing the landing gears failed during two separate occasions making the RCAF questioning the aircrafts capabilities. A lot of these problems left the Avro Arrow ineffective during many scenarios.Clearly it was smarter to invest in missiles which could get the job done easier and would cost less than half the price of the existing program. Cancelling the Avro Arrow program was a better and more economically stable decision by John Diefenbaker and his government. The program cost way too much money for our nation to afford. The program turned out to be a complete disaster and a huge waste of time and money.With a new era of anti-aircraft technologies emerging, the government found missiles to be much cheaper than interceptors and just as effective. With the BOMARC missiles we also got a bonus by having the Americans as our part nered Allies with whom we could share our defense techniques with. Due to the complications with the designs the Avro Arrow had many problems too expensive to solve with the existing price tag. The government clearly made the right and smarter decision by cancelling the Avro Arrow program.
