The Global Fast-Food Industry

Colonel Harland Sanders joined his first establishment in Salt Lake City, Utah in 1952. In 1956 he sold the Corbin, Ky. eatery he possessed, and started bridging the United States to sell new establishments. Soon thereafter he sold his first worldwide establishment in Canada. By 1960 there were in excess of 200 Colonel Sanders Recipe Kentucky Fried Chicken (KFC) outlets. In 1963 incomes were over $500 million and the quantity of outlets had expanded to more than 300. In 1974 at 74 years old, he offered the business to Jack Massey and John Brown for $2 million, one of the extraordinary deals in business history. The Colonel remained on with the organization in a stately job, regularly assisting with opening new establishments. Earthy colored and Massey developed the business all through the United States throughout the following quite a while and in 1966 took the organization open, posting it on the New York Stock Exchange and the Colonel was permitted to buy the initial 100 offers. The year 1969 was a significant one throughout the entire existence of the organization with the principal significant infiltration into universal markets outside North America by procuring establishments in England and Japan. By 1971, there were in excess of 2400 establishments and 600 organization possessed eateries spread all through the United States and 47 different nations. 1971 turned into another key year in organization history with the offer of KFC to Heublein. This was Heublein†s first huge section into the café business and it didn't go easily. By 1977 café quality had declined and the Colonel was disturbed. Just around 20 new eateries were being opened every year. Accordingly, Heublein executed another system underlining clean eateries, item consistency across establishments and better help. Old establishment structures were renovated. In 1982 R. J. Reynolds Inc. (RJR), trying to enhance past the tobacco business, procured Heublein for $1.2 billion. KFC was productive and developing again, however Colonel Sanders never observed the final product of Heublein†s methodology in the late 1970†³s, in light of the fact that he passed on in 1980. RJR kept on running KFC as an independent business for quite a long while. In 1985 it procured Nabisco and in 1986, in anticipation of the resulting move to take RJR Nabisco private, it sold KFC to PepsiCo Inc. for $840 million, over the complaints of previous Heublein director, Stuart Watson. Additionally this year the Colonel Sanders Technical Center in Louisville, Kentucky was built up. The securing by PepsiCo was a critical defining moment in the company†s history. In past acquisitions by Heublein and RJR, KFC had been worked as a different element, in spite of the fact that in various manners. Heublein attempted to utilize its own directors to work KFC, while RJR embraced a totally uninvolved methodology. PepsiCo was looking to the securing of KFC to make some collaboration inside its different activities. As of late rebuilt into three significant divisions, soda pop, nibble nourishments and eateries, PepsiCo could cross-fertilize between divisions, for example by selling its sodas in cafés. PepsiCo†s culture was additionally very different than KFC. PepsiCo set a solid accentuation on representative presentation, while KFC†s culture was progressively laid-back in the southern custom. In 1991 a change was made that was to have unintended outcomes. Kentucky Fried Chicken chose to change their name to KFC for a few reasons, as per the site Snopes.com, A transition to de-stress â€Å"chicken† on the grounds that KFC intended to offer a fluctuated menu that included different sorts of food. (The Boston Chicken enterprise adopted a similar strategy for a similar explanation, changing their name of their retail food outlets to Boston Market.) A longing to wipe out the word â€Å"fried,† which has negative meanings to the undeniably wellbeing cognizant purchaser showcase. An ongoing pattern towards the contraction of long business titles, as exhibited by other organizations' utilizing abbreviated types of their names, for example, The International House of Pancakes (IHOP) and Howard Johnson's (HoJo). Because of this name change, bits of gossip later started coursing all through the web that the legislature had constrained KFC to change its name since it was done utilizing chickens. As per the talk, KFC was delivering a hereditarily modified chicken with more than the typical measure of extremities. Notwithstanding the way that a portion of these cases, for example, chickens without snouts, quills or feet, are past logical capacities, the gossipy tidbits have persevered. Throughout the following quite a while, KFC kept on succeeding and experience changes. It pulled together its procedure to build the traffic in singular establishments by extending the menu to speak to a bigger gathering of purchasers. In 1993 the organization added non-seared chicken to menus in the U.S. what's more, Australia, and in 1994 KFC authoritatively opened its 9,000th eatery on the planet, in Shanghai, China, and declared a $200 million speculation throughout the following four years for 200 eateries in 48 Chinese urban communities. 1995 saw the presentation of Colonel's Crispy Strips and Chunky Chicken Pot Pie. The first KFC café in Moscow was opened. In 1996 KFC presented Tender Roast chicken pieces and brought back one of the world's most perceived bundles, the basin, and in 1997 the organization presented Honey BBQ-seasoned Tender Roast, Spicy Buffalo Crispy Strips and Chicken Twister, which are wrapped up chicken and vegetables. Regardless of every one of these advancements and upgrades, PepsiCo had gotten progressively discontent with the eatery division. Maturing offices were requiring a significant part of the parent company†s income to be spent on renovating cafés and in this manner ignoring interest in the soda and nibble food organizations. While trying to come back to its underlying foundations, PepsiCo spun off the whole eatery division into a traded on an open market organization, Tricon Global Restaurants in October 1997. In May 2002, with the obtaining of A&W and Long John Silver's, Tricon changed its name to Yum!. One of the primary vital issues introduced for this situation is the subject of whether KFC should keep on growing universally and where. Since the beginning of its commencement, KFC has been included outside the United States, having extended to Canada in 1956 and afterward in a significant move in 1969, to Japan and England. Starting at 2000, of the thirty-five biggest inexpensive food chains, KFC was second just to McDonalds in the number nations entered. It is a field where KFC has had huge achievement and should keep on being included. Starting at 2001 KFC had in excess of 500 outlets in China contrasted with just around 400 for McDonald†s. KFC beat McDonald†s to China by five years, opening their first outlet in Beijing in 1987. Market reviews in China by AC Nielson have demonstrated an inclination for KFC over McDonald†s, both as far as items and the outlets themselves. Likewise, the Chinese have social predisposition for chicken over meat. This is positively a zone where KFC should keep on misusing its bit of leeway. Latin America is another worldwide region where KFC has a solid nearness. In the Central American, Caribbean and Mexican region, KFC is serious with McDonald†s and Burger King regarding number of outlets. It has an especially solid nearness in Mexico and the Caribbean. Just in the Southern piece of Latin America does KFC fall forcefully behind McDonald†s. With the appearance of the North American Free Trade Agreement (NAFTA) nature has changed in Mexico. An accommodating component is that one of KFC†s significant providers, Tyson Foods, has significant chicken offices in Mexico. The world of politics has changed with the appointment of Vicente Fox. KFC†s effectively solid nearness ought to be extended forcefully. They ought to likewise utilize this base in Mexico as a methods for contributing cash-flow to additionally grow the establishment base all through South America, so as to discredit a first-mover advantage by McDonald†s and Wendy†s. Establishment outlets require less capital than organization claimed cafés, and are in this manner a faster manner by which to grow. Anther key issue confronting KFC is the choice to establishment or extend by organization claimed cafés and whether to refranchise. The first system of Colonel Sanders and his prompt replacements was to establishment and not manufacture organization possessed eateries. This permitted them to become snappier than they would have if KFC had basically put resources into organization claimed eateries. This procedure proceeded until the acquisition of KFC by PepsiCo. Due to a conflict in corporate culture among KFC and PepsiCo, and the nearness of a solid franchisee bunch inside KFC, PepsiCo left on a procedure of repurchasing more fragile establishments and running them. At the hour of the side project of KFC and the café division into Tricon Restaurant Group in 1994, the level of organization claimed eateries was about 40%. After the side project, Tricon the executives started to strip of a considerable lot of the organization claimed outlets. This was the aftereffect of an adjustment in mentality with respect to Tricon the executives. They didn't put stock in supreme control of all parts of the nearby business and were eager to concede that the franchisees realized the neighborhood business better than they. Constantly 2000, the quantity of organization possessed outlets had dropped to 27%. As appeared in the SWOT examination beneath, there are various factors in the outer condition that KFC ought to consider while detailing and executing procedures. A portion of the more significant viewpoints are brand name mindfulness, worldwide market development, contracting assets accessible to outlets and assaults by lobbyist gatherings, for example, PETA. On the positive side, the brand name mindfulness is a huge resource for KFC. The move in 1996 to bring back the pail was probably the best choice in its history. Moreover, worldwide market development presents a gigantic chance to KFC to develop. They should expand on their current worldwide base and keep on developing establishments.

Masdar City An Example for Cleantech Innovation

Masdar City An Example for Cleantech Innovation © Shutterstock.com | LMspencerThe low-rise, mixed-use high development city that is Masdar and the pride of Abu Dhabi, is a wonderful example of existing and growing cleantech innovation. This article takes you through 1) introduction to Masdar, 2) features, 3) commercial occupants, 4) support and criticism, and 5) first private homes on the way.INTRODUCTION TO MASDAR CITYWhat is it?Masdar City is one of the few successful examples of arcology â€" structures incorporating architectural design principles for thickly populated habitats (hyperstructures) with the aim of minimizing environmental impact. The project depends on solar as well as other sources of renewable energy. The construction of the city was begun with the objective of creating it the world’s first completely sustainable, zero-emission city. The ambitious city was first announced in 2006 as a $18-22 billion project.How did it happen?The U.A.E President and ruler of Abu Dhabi, His Highness Sheikh Khalifa bin Zayed Al Nahyan, was aware that oil â€" the key source of Abu Dhabi’s wealth, would one day run out. So, he asked his advisers to develop a long-term plan that would enable the country to expand their economy away from hydrocarbons. The solution they arrived at was renewable energy. Abu Dhabi could be a part of the global energy campaign and make money from it too.The idea was to build a fully functional city, the making of which would trigger better local comprehension of and more investment in green technology and industry. Expertise in those industries would in the short term enable the Emirate to sell more of whatever remaining oil it had overseas, and in the long term, offer them considerable revenue. It was also expected that by providing office space to eco startups and housing a green-concentrating university, the city could function as an incubator for a fresh generation of Emirati greentech entrepreneurs. This in turn could help invigorate a local population used to big pay packe ts and subsidies and, it was hoped, additionally, boost Abu Dhabi’s international reputation.Who is handling the project? © Flickr | GDS InfographicsSultan Al Jaber, a young Emirati with an MBA, and an economics Ph.D. from Coventry University was entrusted with the massive task. As of December 2013, the 39-year-old was leading a team of 233, and doubling as a cabinet minister. In 2006, the team was just six-member strong. Masdar, an auxiliary of Mubadala Development Company is heading the project. The contract was awarded to design practice Foster with the team being led by Evenden (currently senior executive partner at the company).FEATURESSolar poweredMasdar is solar powered by way of a 54 acre (22-hectare) field of 87,777 solar panels. There are also solar panels on the city’s roofs. The initial plan was to power the whole city using on-site means such as rooftop solar panels. However, later, it was discovered that developing a solar field on the ground and in the center of the desert was more efficient. It was easier to make a man brush these solar panels on the ground rather than to have to acce ss individual buildings to clean the solar panels on their respective roofs.With respect to solar panels, blowing sand that sticks on the panels has come as an obstacle. So Masdar has been collaborating with other companies to build surfaces having smaller pores then those of sand particles to keep the sand particles from sticking. Work is also in progress towards coatings that repel bacteria and sand which could be used on solar panels and various other applications.According to Foster + Partners, the land around the city would contain photovoltaic and wind farms, plantations and research fields, enabling the community to be fully energy self-sufficient.Architecture and temperatureThe city’s construction resembles that of ancient Arab cities, and the temperature is cooler than the surrounding desert.This cleantech city has terracotta walls adorned with arabesque patterns. To people viewing the city from a distance, it appears to be a cube. Foster’s design team began their proje ct by touring ancient cities such as Muscat and Cairo to see what it was that kept these cities cool. They discovered that the solution these cities had to handle hot desert temperatures was narrower; shorter streets typically extending no more than 70 meters. The streets’ end buildings generate adequate wind turbulence to propel air upwards leading to a flushing effect that keeps the street cool. Following this model, the streets in Masdar are also short and narrow, and buildings are clustered together to form walkways and streets protected from the sun. A wind tower 45 meters high and modeled on conventional Arab designs sucks air from above and channels a cooling breeze through the city’s streets.The vertical faces of the buildings are clothed with screens that resemble a terracotta mesh. These screens keep the sun out while allowing entry to the breeze. The design of the walls (cushions of air restrict heat-radiation) has helped decrease demand for air-conditioning by an ama zing 55 percent. A cooling effect is also contributed by the site being at a raised level compared to the surrounding land. Owing to the distinct architecture that keeps the city cool, the temperature here usually seems 15 to 20 degrees less than what’s felt in the surrounding desert.Palmwood is used as an exterior wood (appears in features such as the entrance gates, doors, and screens) all through the city. Palmwood is a sustainable hardwood-substitute created by Pacific Green and utilizing plantation coconut palms that have ceased to bear fruit.BioFuelsWonderful development in biofuelsSaltwater fed desert plants could provide jet fuel for companies such as Etihad Airways and Boeing.No water taps or light switches to cut water and electricity use, green water management.Water and lighting are controlled by movement sensors that reduce water and electricity consumption by 55 and 51 percent electricity. In addition, about 80 percent of utilized water would be recycled.Waste water would be recycled as many times as it can be recycled and would be used for crop irrigation and other applications.PV (photovoltaic) panels are cleaned with water only twice a year. The remainder of the year, the cleaning is done manually with brooms.TransportationPractically car-free, walking is encouragedThe nearest rapid transport connections and amenities are at a maximum distance of 200 meters, thereby encouraging the practice of walking. Almost all cars have been replaced by a set of driverless electric vehicles that take residents around under the site.The first design banned automobiles, with the intention of accomplishing travel through PRT (Personal Rapid Transit) systems and public mass transit, with existing railways and roads linking to other locations outside the city. As per an amended design, public transport within the city would depend on means other than PRTs. Instead, there would be a combination of clean-energy vehicles and electric vehicles for mass transit wit hin the city. Most of the private vehicles would be limited to parking lots along the city’s perimeter. The emirate’s existing metro line and light rail would link the cleantech city’s center with a greater metropolitan area.Shams 1Possibly the most noteworthy of what Masdar has to offer is situated even further afield. This is Shams 1, the Middle East’s biggest solar plant and the world’s biggest CSP (concentrated solar plant) at 100MW with 258,000 mirrors and a huge (220 tons) custom-made 125 MW steam turbine produced by MAN. It is a 100MW solar field situated on a 2.5 square kilometer plot of land, 150 km southwest of Masdar. The solar field is so huge that even for a person looking from atop a sand dune situated 75 meters away, the site goes beyond his field of vision. Though the $600 million costing plant is situated outside Masdar City, it is an essential aspect of the project’s story. This plant is just one of a number of green tech projects that Masdar executed. The funding for Shams 1 comes from Masdar’s investment arm.Shams1 is ten times larger than Masdar City’s and functions differently. It has no panels, only curved five-meter-wide mirrored blades sparkling in the heat. Each of these blades reflects the sun’s 40-degree centigrade rays on to the center of a pipe of liquid. The considerable concentrated heat causes the liquid to be heated to a temperature of several hundred degrees celsius. The liquid is then pumped through an on-site station â€" the heat producing electricity that would save 175,000 tons of carbon dioxide each year. Finished at the beginning of 2013, the solar plant would take 20,000 Abu Dhabi homes off-grid.Masdar City Welcome Video COMMERCIAL OCCUPANTSMasdar InstituteThe Masdar Institute of Science and Technology (MIST), a graduate level research university concentrating on environmental sustainability, clean technology and alternative energy was the cleantech city’s first occupant. The Institute was responsib le for the engineering plans of the energy efficient city and is the focal point of research and development activities.MIST’s building, developed with the help of the Massachusetts Institute of Technology utilizes 70 percent less electricity and potable water than regular buildings of a similar size. It is also fitted with a metering system that continuously monitors power consumption. The campus has been designed in a manner that highlights the flexibility, modern materials, and the adoption of traditional architectural elements to enable an optimized blend of natural lighting and cooling to minimize energy requirements.By 2013, the institute was 336 student strong, of which 42 percent were from the U.A.E, and 35 percent were women. The faculty and students of the Masdar institute are involved in more than 300 joint projects with academia, government agencies, and private enterprises. Their research tends to center on smart grids and smart buildings, renewable energy, environmen tal engineering, electronics, water use and energy policy and planning.SiemensMasdar City is home to a regional headquarters for Siemens. Designed by the British architecture firm Sheppard Robson, the LEED platinum building is the most energy economizing in the whole of Abu Dhabi. It utilizes energy efficient and sustainable building techniques and materials.The 130,000 square-foot building has been constructed around the concept of a “box within a box.” The structure incorporates an airtight and highly insulated inner façade that insulates from the sun and a lightweight shading system made of aluminum on the exterior. Under the building, the plaza is funnel-shaped. This shape is useful for sucking winds blowing at the time, beneath the building. Thanks to the Venturi effect, a breeze moves through atria in the building structure, up to the building’s roof, cooling public spaces without energy expenses. In addition, the atria enable daylight to enter the building center so as to decrease the need for artificial lighting, thereby bringing down energy consumption further. All the building’s automation systems are from Siemens.The building has won several awards including the award for best office building (MIPIM Architectural Review Future Projects Awards 2012) and best office architecture (International Property Award Winners Arabia 2012).IRENAAs of May 2013, construction has begun for the headquarters of the International Renewable Energy Agency (IRENA) in Masdar City. The headquarters of IRENA, co-located with the Masdar headquarters, would generate renewable energy from the 1,000 square-meters rooftop photovoltaic solar panels to deliver renewable energy. The building would also incorporate systems to achieve water usage that is less than 50 percent that of a typical building in Abu Dhabi.The combined headquarters campus would comprise three buildings on the territory of the 32,000 square-meter complex. There would be a common community courtyard f or the buildings that would connect the offices to restaurants, shops and open areas.Incubator buildingThe Incubator building is perhaps the most futuristic of all structures in the city. A cuboid structure constructed around a central core that is fixed with drought-resistant plants, the building was made with recycled aluminum sheets and extrusions, and recycled structural steel in keeping with Masdar’s attempts to encourage a sustainable supply chain of materials. Dressed in colorful ceramic plates that assist the Incubator building with meeting Masdar’s strict energy requirements, it also functions as something of a huge mirror that reflects the surrounding campus.The Incubator building incorporates office and retail space to accommodate regional offices for multinationals, start-ups, and small-and-medium-sized enterprises. It was designed to house approximately fifty companies and to attract brilliant companies and people who would like to research and engineer sustainable water and energy projects in a free economic zone.Some of the prominent tenants in the building are Mitsubishi, General Electric (GE) and Schneider Electric. GE’s ecomagination center in Masdar City is the center’s first ever ecomagination center and also the first resident in the 10000 square meter, four storey Incubator building. The center offers exhibitions and training on water and energy efficiency.SUPPORT AND CRITICISMThe project is supported by many major entities including the U.S. government, the World Wide Fund for Nature (an international conservation charity), and Greenpeace. In response to the project’s dedication to zero waste, zero carbon and other environmentally friendly objectives, WWF and the sustainability group BioRegional have endorsed the city as an official One Planet Living Community. The Alliance to Save Energy honored the city with a 2012 EE Visionary Award in appreciation of the city’s contributions to the furthering of energy efficiency.Just as Masdar City has its advantages, it has its shortcomings too:The city has no affordable housing, so a considerable number of the city’s workforce have to drive to their jobs. The city’s only residents are the university’s students.Though Greenpeace supports the project, they emphasize that more importance should be attached to retrofitting already existing cities for greater sustainability rather than building new zero-carbon cities from scratch.Life in the city is not urban. There are just a small number of cafes, a bank, a travel agency and an organic supermarket. However, the cafes are dead outside of mealtimes and the only customers for the travel agents are the lecturers.Some skeptics are of the view that the city would only be representative of Abu Dhabi and that it would turn into a luxury option for the affluent.Another disadvantage is the inaccessibility of the cleantech city from central Abu Dhabi.Masdar: The City of the Future | Fully Charged FIRST PRIVATE HOMES ON T HE WAYAs per information from May 2014, Masdar is taking key steps to developing the cleantech city’s first private homes. The 500 new houses, to be designed by Woods Bagot promise to be super sustainable and completed within the next two years. As per a report from The National, the development has already been leased in full to educational establishments and corporations to be owned by Masdar. This plan is part of a bigger $15-18 billion development plan that would result in 2,000 homes to accommodate a maximum of 40,000 residents and 50,000 workers.It is likely that Masdar Institute educators and students, and representatives and blue collar workers of businesses (large and small) that set up shop in any of the six office plots, would take up residence in the new neighborhood. However, there would also be 750 homes available on the open market.The Masdar City project is expected to be completed in the period between 2020 and 2025.

Dna Evidence And Its Repercussions - 1374 Words

We will examine the importance of DNA in the conviction of Tommie Lee Andrews and the significance of this decision in the United States Judicial System. We will discuss an overview of some of the essential elements in conducting utilizing this DNA evidence and its repercussions. This case signified the first time in the United Sates that DNA evidence was actually admissible in court proceedings during a criminal trial. In 1986, in a neighborhood around the Orlando, Florida area a series of violent rapes had the city on edge. One of the victim s names was Nancy Hodge, who was brutally raped at knifepoint by her attacker. She only briefly saw the attacker and was not able to immediately identify him due to his hands having covered her†¦show more content†¦Due to the brief period that Hodge had been allowed to see her attacker, the prosecution felt that stronger evidence was needed to prove a connection.

This relatively new forensic investigation technic involving the use of DNA fingerprinting was in its infancy and was pioneered by a British scientist might hold the answer to convicting the rapist. Because the mistrial of Andrews caught the prosecution off guard due to not having appropriate information or statistics of its viability, a new plan was needed. The prosecution felt that a stronger case against Andrews was needed to proceed in court. The prosecutor contacted a colleague familiar with principles of the DNA evidence in England for guidance. He then contacted a company in New York used to develop methods of DNA profiling or fingerprinting for assistance. Once the results of testing were completed in this case, it positively matched two of the six rapes being investigated.

Founding and History of the New Jersey Colony

John Cabot was the first European explorer to come into contact with the New Jersey shore. Henry Hudson also explored this area as he searched for the northwest passage. The area that would later be New Jersey was part of New Netherland. The Dutch West India Company gave Michael Pauw a patroonship in New Jersey. He called his land Pavonia. In 1640, a Swedish community was created in present-day New Jersey on the Delaware River. However, it is not until 1660 that the first permanent European settlement of Bergen was created.   The Motivation for Founding the New Jersey Colony In 1664, James, the Duke of York, received control of New Netherland. He sent a small English force to blockade the harbor at New Amsterdam. Peter Stuyvesant surrendered to the English without a fight. King Charles II had granted the lands between the Connecticut and Delaware Rivers to the Duke. He then granted land  to two of his friends, Lord Berkeley and Sir George Carteret, that would become New Jersey. The name of the colony comes from the Isle of Jersey, Carterets birthplace. The two advertised and promised settlers many benefits for colonizing including representative government and freedom of religion. The colony quickly grew. Richard Nicolls was made the governor of the area. He granted 400,000 acres to a group of Baptists, Quakers, and Puritans. These resulted in the creation of many towns including Elizabethtown and Piscataway. The Dukes Laws were issued that allowed for religious tolerance for all Protestants. In addition, a general assembly was created. Sale of West Jersey to the Quakers In 1674, Lord Berkeley sold his proprietorship to some Quakers. Carteret agrees to divide the territory so that those who bought Berkeleys proprietorship were given West Jersey while his heirs were given East Jersey. In West Jersey, a significant development was when the Quakers made it so that almost all adult males were able to vote.   In 1682, East Jersey was purchased by William Penn and a group of his associates and added with Delaware for administrative purposes. This meant that most of the land between the Maryland and New York colonies were administered by Quakers.   In 1702, East and West Jersey which were joined by the crown into one colony with an elected assembly.   New Jersey During the American Revolution   A number of major battles occurred within the New Jersey territory during the American Revolution. These battles included the Battle of Princeton, the Battle of Trenton, and the Battle of Monmouth.   Significant Events New Jersey is divided into East and West Jersey in 1674. It is reunited in 1702 when it becomes a royal colonyNew Jersey was the third state to ratify the ConstitutionNew Jersey was the first to ratify the Bill of Rights

Movie Review Free Essays

There were rules to be followed, and a person should not act differently from others. But in the end, everything changed when Sam and Suez finally decided to run away and lives on their own. After the upbringing, the whole community started to find the love, between Sam and Suez, harmful. We will write a custom essay sample on Movie Review or any similar topic only for you Order Now It caused the disruption within the stagnant plot of the story, in a way that they were different from what was usually considered correct by the norm. This disruption elevated the twists and turns of the events within the movie. Also because of this, the members of the community started to suffer, and started to find a solution on how to solve this disruption within the community. From living normal, he members of the community started to form this consciousness to each other that resulted to their own involvement in the love between Sam and Suez. However, this did not mean that the community itself as a whole started to form a unity instantly; it was only a step-by-step process that eventually led to the involvement and solidarity of the characters. The community as a whole created the status of each of the characters. It Implemented rules and regulations; from what Is right, to what Is wrong. These biases made by the society led to the corruption of each character that resulted in heir fixed role in the community. For example, the Khaki Scout Trainer was a Math Teacher but because of the community where he was in, he was forced to become a Trainer. Generally, by these biases made by the Community, the members within it started to view everything as normal, and began to be unconscious to others. In the division of the community. This showed that the bias led by the community as a whole produced a bias to an individual, and caused dissever of its member. When the community started to act, due to the subject of love between Sam and Suez, each character started to be involved. From Cam’s side of the story, his foster parents started to ignore their own responsibilities to him, unlike the Khaki Scout Trainer and the Island Police Officer, who were treating him as a family. And from Guy’s side of the story, her parents started to pay attention to her maturity due to her issues of rampaging, and being introvert from the rest of her schoolmates. These transformations made by each character showed the manifestation of the romantic convolutions of the two young characters. But as a whole community, this love between the two at first was not accepted because of their age. In the end, due to the early maturity of the young lovers little-by-little the community started to acknowledge their love, thus showed the transformation of the community from being stagnant to a community whose members were involved and united. In addition, the involvement of each character to the love between Sam and Suez, made the portrayal of each scene focused from the island’s community to each individual that involved themselves within the issue. The portrayal of each scene from the start of the movie was all about the community and the island itself. It focused on the stagnant community that deals tit their own problems. The people in New Penance had been following the rules and biases done by the community itself. It showed that the portrayal of the scene is on a slide manner that depicted one scene then shift to the other. It also described New Penance by showing the place, and by using a Journalist to give information. The way the Journalist’s report, at the start of the movie, is on a fixed manner. The journalist gave information, but the way his report portrayed was that his background was fixed and instantaneously shifting from one idea to the other. This showed that the movie at the start was in a state of stationary ideas that had been made by the community that had been adapted by its members. After the upbringing of the love between Sam and Suez, there was a sudden changed in how the scene had been portrayed. First, it focused more on the two- young lovers. The portrayal of each scene about the lovers transformed the scene from being stationary to being alive. There was a beginning of a conversation and showing of each other’s actions. Second, it also focused on the involvement of each character. By the time the upbringing happened; the community started to act, and by this action, the scene portrayal started to show the strengths and weaknesses of each character in the story. Lastly, it also dealt with the recovery of the way how it was presented at the start. At the end of the movie, on how the scene that had been being portrayed was the same on how the scene had been portrayed at the beginning. This showed that even though there was a transformation within the community as a whole, the depicting of the scene started and ended with the same portrayal. How to cite Movie Review, Papers

Business and the economy Essay Example For Students

Business and the economy Essay Task 1Discuss whether firms like Rechem should be allowed to import chemical waste from overseas to be disposed of here in the U.K. ANALYSIS Rechem have thirty years of experience in solving environmental problems caused by a wide range of hazardous and toxic materials. Their range of services included the following:Waste ManagementLogisticsIncinerationProject ManagementRecyclingEnvironmental Monitoring (See APPENDIX A)DISCUSSIONNot all Countries in the World have the ability or the technology to safely dispose of chemical waste such as polychlorinated biphenyls (PCBs). It may be argued that it is more desirable and safer to move the waste to another country for disposal. The alternative of storing the waste for long periods of time may result in serious problems and consequently cause pollution effecting living organisms beyond the host countries borders. There has been instances where one countrys pollution problems in turn pollute neibouring countries such as Mercury used in manufacturing process eventually leaking into river systems (This happened between Canada and the United States). Another example is acid rain caused by burning fossil fuels without capturing or burning off the chemicals that cause acid rain, for example, UKs industrial plants affecting the forests of Germany and Scandinavia. Chemical pollution has no boundaries, dumping chemical in the North Sea by the northern European countries not only destroys the food chain in that area, but, with tidal and ocean currents, this pollution can affect organisms and eventually human beings on the other side of the globe. Pros:- of firms like Rechem importing disposing chemical waste:1. Helps the environment because it discourages landfills. 2. It breaks chemicals down at high temperatures not a low normal temperatures which can be dangerous. 3. It can break down PCBs which are extremely dangerous. 4. Brings money into the British economy. 5. Supplies jobs for workers. 6. Licences for this type of disposal is limited and helps the environmental factor of other countries that do not have this process and have to resort to landfills or burning the waste at dangerously low temperatures like, America and Germany. 7. In the eighties many articles on green companies and industries featured Rechem 8. Rechem were praised by the Minister for the Environment at the time as true friends of the earth9. Rechem were acknowledged as a world leader in the safe incineration of dangerous chemicals. Cons:- of firms like Rechem importing disposing chemical waste:1. Britain is taking other countries and disposing of it for them and the sub product of the incineration product is released into British air. 2. The research to test if it is fully liable is limited and seems to be on a trial and error basis. 3. Profit and shareprices seem more important than environmental issues. 4. The world is more environmentally aware. 5. Bad press as stories circulated about babies being born with eye malformations and also diseased cattle near Rechem plants. 6. The Daily Telegraph reported that tests on foliage samples near the South Wales Rechem plant showed PVBs to be 50-100 times the pollution inspectorates advisory limit. 7. A Welsh Water Authority document stated that the Pontypool plant had discharged up to 82 times the permitted levels of lead, copper, zinc and nickel into the sewers. 8. Trouble of removing bad press scars about the safety of disposing chemicals without discharging polluted air and that it can dispose of the ash and residue without contaminating the locality. 9. PCBs are highly dangerous and are believed to cause cancer and damage to the liver. 10. Contaminated cargoes of PCB would have to be transported to the treatment plant on the road sea and air, any accidents in these situations would be disastrous and puts the British people and wildlife in a precarious situation. 11. Dock workers and employees refused to handle PCBs from Canada. 12. Most of Britains larger ports refused to handle PCB material. Economics of Importation of Chemical Waste Rechem have been fortunate in the market of disposal of chemical waste due to booming demand for this service where capacity could not be increased quickly due to planning permission restrictions at home and abroad. By year end March 1988, Rechem made a profit of 4.5M out of a turnover of 13.4M, which equals a 33.5% profit, the first years profit on a turnover of 19.5M was 45% at 8.8M. We can conclude that there are huge profits to be made in this area. Rechem have completed a floatation on the stock market selling 2.6m shares therefore increasing their exposure to external pressure groups. Another factor to consider is Balancing internal and external expectations. Internally, a business usually needs to make a profit for shareholders, managers and other stakeholders. Externally, the business has to contend with selling products in the face of competition and the regulatory influences exerted by governments. It also has to take into consideration the interests of external stakeholders and the pressures from a variety of other independent factors. Failing to take heed of organised pressure groups such as Friends of the Earth, the National Anti-Vivisection Society and Greenpeace may lead to the worst possible outcome a consumer boycott, perhaps on a international scale. Banks and Investment Bodies like Pension Funds and individuals (public) are now paying more attention to their exposure to environmental risk and investors are starting to show concern about risks posed by companies with poor environmental records. Task 2Not all pressure group activity is as highly publicised as that of greenpeace. What other forms does it take and what is its purpose. ANALYSISA pressure group is really an agent of activity representing an interest group. Interest groups would, in the main, like to influence the Government, rather than to become the Government. Clearly this can change, as with the emergence of green interest groups who have fought elections on environmental and other issues. However, the majority of interest groups do not make this transition, concentrating instead on putting pressure on Government on particular issues, or carrying out other activities. The Confederation of British Industry (CBI) acts as an interest and pressure group, but also carries out work in research and training. Forms of Pressure Groups1. Greenpeace2. Friends of the Earth3. National Trust4. Royal Society for Nature Conservation5. Civic Trust6. The Media (Newspapers, Television, etc.)7. Wildlife Trusts (RSPB, etc.)8. The local community (Residents, Farmers, etc.)9. Government/National Local council/government 10. Trade Unions (represent Employees, and other aspects, Dock Workers.)11. Professional Associations12. Consumer Groups13. Businesses14. Anti-Incineration Campaigners Communities Against Toxics (CATs), UK and Norwegian and British Green Parties fighting with waste incineratorsPurpose of listed Forms of Pressure Groups The Media To present the concerning public with fact based stories on economy and environmental issues and anything that is endangering the environment or the British public and analyse the activities of possible dangerous companies or industries. Wildlife Trusts Look into anything that could upset the environmental balance and effect the surrounding wildlife, to make sure waters are not being polluted that will kill fish and animals that food source is in the rivers and thus affects the whole food cycle. Medical Marijuana EssayThe long term impact on the health of the countries in the grip of the haze- Indonesia, Malaysia, Thailand, the Philippines, Singapore, Papua New Guinea and Thailand is impossible to gauge. City-dwellers in South-East Asia have long been used to breathing a noxious cocktail of car-exhaust fumes and industrial pollutants. Those with existing respiratory illnesses, eye and skin irritations and heart complaints will now find their conditions severely aggravated. But those free of such disease may start developing them. There seems little that the authorities can do. One Malaysian minister suggested that two million people should be moved out of harms way, but this idea was dismissed as being impractical. Another proposal was to sprinkle water from the skyscrapers to dissolve the soot. Ordinary people have resorted to the few countermeasures available to them. They lock themselves indoors whenever possible and the price of surgical masks has more than doubled since the smog discended. An official said fires continued to burn in Indonesia. For this reason, the haze was not expected to clear at least until the north-east monsoon in November. More than 1,000 Malaysian fire-fighters have been deployed in Sumatra to help Indonesia battle the blazes, which has caused the blanket of smog over Indonesia. Other problems have happened to Malaysia since the smog caused by forest fires in Indonesia like the collapsing stock market, free-falling currency and the subsequent cancelling of several government backed mega-projects like, the Commonwealth Games, which promised to be the biggest in its 68-year history. Financial CostsCurrency crises and slumps on the stock markets in several countries showed that the Asian Tigers, some of the worlds fastest-growing economies, are no longer roaring. The skyscrapers in the Malaysian capital Kuala Lumpur, symbols of the regions wealth, were barely visible and the Petronas Twin Towers, the worlds tallest building, was just a ghostly form in the mist. And with factories throughout the region having to scale down activity, the world economy could also be hit, with prices rising in the electronics industry, which the region dominates. Tour operators are offering alternative holidays and refunds to hundreds of holidaymakers who were due to travel to South-East Asia, which was still blanketed in smog caused by the forest fires in Indonesia. The tourist industry would be severely damaged as people would be declined to visited a country so heavily polluted and this will mean less foreign income and could result in unemployment and unrest. The Malaysian ringgit and Indonesian rupiah hit an all time low in September as currency dealers began to fear the economic consequences for the regions of the forest fires in Indonesia which have covered much of South-East Asia in a noxious smog. The Ringgit had fallen 20% since July, closed at 3.1800, down from 3.1300 against the dollar. The rupiah fell from 3,100 to 3,220. The fires have affected tourism as well as investor sentiment, which was already low, Peter Von Maydell, currency economist at investment bank UBS, said, But the economic fundamentals in these countries remain extremely poor in any case Intemperate remarks by the Malaysian foreign minister, Adbuliah Ahmad Badwi, did not help the currencies. He said the regional economic crisis was precipitated by currency speculators..driven by sheer greed. The only positive aspect in the region was the Thai baht remained steady at 35.50 to the dollar after the Bangkok parliament approved reforms to the constitution on which the $17 billion IMF loan package to the country is independent. In November 1997 Thailands squabbling and discredited parliament produced its fifth prime minister in as many years. While this was happening Chuanpis Charoenigam was selling one of her nine Mercedes-Benz at a flea market in Bangkok. The former property broker was unimpressed by this attempt to prevent Thailand once the worlds fastest-growing economy from becoming Asias biggest economic embarrassment. A former banker was selling two Mercedes: Buy both for $100,000 (60,000 pounds) and get this small passenger plane for free!. Another dispossessed estate agent was selling off his wine cellar. Bottles of Chateau Lafite 1981, one of the best vintages of the century, were going for 30 pounds each. These luxuries are the casualties of an economic crisis which has seen the baht devalued by 50 per cent. Factories close, tens of thousands of people lose their jobs and the International Monetary Fund spends more than 10 million pounds on an aid package that has not worked. The turmoil is a fa r cry from the brash confidence of what was Asias slickest Tiger economy. Previously the country was taking annual growth of eight per cent for granted, a new Mercedes showroom was opening every other week and skyscrapers rose like souffls out of the polluted logjam. Now the souffl has collapsed with vengeance, and Thailand, a country without state welfare, is bracing itself for full-blown recession. President Suharto of Indonesia shut 16 banks in an attempt to convince the IMF that it is serious about cleaning up its economy and especially its corrupt banking sector. Prime minister Chavalit Yongchaiyudh presided over a borrowing binge which produced a domino-effect of bad loans. Billions of dollars, provided at cheap rates by western banks eager to cash in on the Thai economic miracle, have been pumped into finance companies controlled by the friends of those in power. Most of the money had gone into costly but unnecessary construction projects. The cheap easy loans failed to take into account that Thailands economic fundamentals had become fundamentally unsound. It is that that caused the disastrous run on the baht in June and triggered the currency crisis in South-East Asia.

Beowulf Essays - Beowulf, Geats, English-language Films, Free Essays

Beowulf Essays - Beowulf, Geats, English-language Films, Free Essays Beowulf The story of Beowulf is one of courage, nobility, and heroism. Beowulf possesses each of these attributes both as a young prince and an elder king. These qualities allow him to become the honored king that he was, yet they also lead to his death. His actions are to be viewed as a precedent for young princes and future kings. Clearly every young prince inspires to earn enough respect to become king in their latter years. Beowulf first earns this respect when he sails to Herot to kill Grendel, the monster that has been keeping the soldiers out of their home. Upon arrival in Herot, Beowulf brags of his past accomplishments, in order to earn some respect from Hrothgar and his men. In my youth I have set about many brave deeds?I had bound five, destroyed a family of giants, and at night in the waves slain water-monsters, suffered great pain, avenged an affliction of the Weater-Geats on those who had asked for trouble- ground enemies to bits. And now alone I shall settle affairs with Grendel, the monster, the demon. (Page 32) While this beast has killed many of Hrothgar?s men, Beowulf vows to destroy him with his bare hands. Even after doing as he so promised, Beowulf has still not finished his duties. The following day, he is faced with another challenge; killing Grendel?s angry mother. When Beowulf is asked to perform this task, he accepts whole heatedly , as he sees it as another chance to gain fame, "Let him who may get glory before death: that is best for the warrior after he has gone from life."(page 45) Once again, Beowulf returns successful in his battle with the monster, only to increase his popularity within his people. These courageous and heroic deeds are expected of any young or aging prince. Clearly Beowulf?s brave encounters with these monsters show his king and followers that he is worthy of becoming a fearless leader. However, his ability to rule goes beyond those feats in battle. Beowulf was showered with gifts of gold and riches for his tremendous achievements of killing the monsters. This is where his manner is shown to be one of strong moral. While he could have easily kept them all for himself, Beowulf gives his rewards to his king, Higlac; as he was instructed to do. In addition, Beowulf declined his first offering at the throne. His sense of morality and loyalty to Higlac tells him that it is only right for Higlac?s son to take the throne before himself. These decent acts should be wisely followed by a young prince. When Beowulf accepts the role of King of the Geats, he does not change as a person or as a warrior. Once again, a monster is brought to the attention of Beowulf, this time in his own land. Even in his old age, Beowulf vows to fight this dragon on his own. Yet this battle was not to be fought for his own fame, yet for the safety of his people. Beowulf attacks the dragon as he had done so many times in the past, in hope of a victory. However, he quickly learns that his strength and armor are no match for the fire breathing dragon. As the fight comes to a close, Beowulf lies dying on the ground, with all but one man left to his aid. Although the dragon was defeated, the Geats lost their honorable king. He died doing what any good leader would, defending his land and people. Beowulf?s mistake was to let his ego take over, as he tried to take on the dragon alone. This is especially notable for a young prince to follow. While it is necessary to be brave and courageous, a prince of king must know his own limitations in order to succeed.

Why do women have facial hair or body hair. What is causing this Research Paper

Why do women have facial hair or body hair. What is causing this phenomena. Can it be cured or changed - Research Paper Example All people have hormones in their bodies that stimulate growth of their bodies and facial hair. It hence depends on the level of hormones secreted, the number of the hair follicles in an individual’s body, and how sensitive they are to be stimulated for growth. Any other conditions or substances introduced into the body that trigger overproduction of the hormones could contribute to excess body and facial hair. This is normally associated to the male gender for its masculine effect. However, women also produce the sex hormone in their adrenal glands and ovaries. Androgen aids in production of oestrogen that serves a greater role in female sexual desires, emotions and satisfaction. Testosterone and adrenal androgens are the main types of the hormone in women; they are released into the blood stream and also produced at the body tissues (body fats and skin) after conversion of dehydroepiandrosterone (DHEA) and androstenedione (A) into androgens at the cells, skin, and hair follicles (Monash University, 2010, p.1). Male bodies produce more of the androgen hormone than women, which is necessary for development of their masculine features (muscles, deep voice, body hair on their chest, inner thighs, arms and lower abdomen and facial hair like mustache and beards among others). Similarly, a high level production of androgen (testosterone) hormone in excess would stimulate excess facial and body hair production in women among other masculine features, a condition termed Hirsutism (Jacoby and Youngson, 2005, p. 2196). As a result, the highly sensitive parts to androgen in women’s bodies have stimulated thick and darker hair growth. This is because the hair follicles in those parts are more sensitive and the higher the number of the follicles, the more the excessive hair on their bodies. Certain diets affect the production of testosterone hormone in a woman’s body. Diets that contain zinc minerals can help to activate testosterone production,

Landmarks in Humanities Second Edition by Gloria K. Fiero Research Paper

Landmarks in Humanities Second Edition by Gloria K. Fiero - Research Paper Example The irony of the beginning and the end of the end of Rome is that the mythic man who built Rome, Romulus, is the name of the last emperor to rule over the state of Rome. Romulus Augustulus was the last emperor of Rome, his reign ending in 476 BCE when Flavius Odoacer deposed the emperor in the name of Constantinople (Illustrated History of the Roman Empire). This change is most often considered the moment that marks the end of ancient Rome and the beginning of the Western European Middle Ages (Schafer and Cohen 100). According to what is known about the last emperor, he was merely a teenager when his empire fell and was allowed to live, retired to the region of Naples with an annual pension. The power of the emperor had run so low that the new regime felt no threat from his living presence (Sass, Weigand, Pearson and Hattikudur 111). The problem with considering the ‘Fall of Rome’ is in determining exactly when Rome fell. If Rome is considered a concept more than a place, the fall of the empire might not have actually occurred until 1453 when Constantinople fell. If it is considered a place, the fall happened much earlier than the date of the deposing of Romulus Augustulus and occurred when Emperor Constantine moved the capital from Rome to Bosporus in Constantinople in 330CE. The only reason that it is considered to have fallen in 476BCE is because the line of emperors was broken during that event, but the fall of the Roman Empire can be considered through a vast number of events which makes the Empire either a short event in history or a very long event in history, spanning more than a millennia (Cunningham and Reich 108). Rome was a phenomenon that has yet to be truly rivaled since its time. At its height, the empire of Rome was spread from Hadrian’s Wall in Briton to the River Euphrates in Western Asia. According to Heather â€Å"interconnected fortress systems, strategic road networks, and professional, highly trained armies both

The High Voltage Electricity Transmission Network Engineering Essay

The High Voltage Electricity Transmission Network Engineering Essay It is well known to many people that high voltage electricity transmission network represents the backbone of the whole regional power supply scheme in the country. The main purpose of this research is analyzing the most frequent common failures in the HV transmission lines and understanding the actual reasons behind these failures in the transmission network of a private electrical company in the Sultanate of Oman named OETC Oman Electricity Transmission Company. The business of that company is providing, developing and governing the Electrical Transmission System in the Sultanate of Oman. The data presented and information provided hereafter shall be considered extremely confidential and hence the assignment information is intended only for the use of this assignment and shall not be distributed to any other party without permission from the original source. In the start, the assignment firstly provides a brief explanation about the company and its role of electricity distribution. Then, it further analyzes different types of equipment failures that are encountered with HV network operation and reported by a local company. It sums up on general findings, results, conclusion and the recommendation regarding future maintenance. Electricity supply Oman Electricity Transmission Company OETC operates, organizes and maintains the majority HV transmission system in which electrical power is transmitted through 220kV and 132kV transmission lines to load centers in Muscat Governorate and the regions of Dakhliyah, Batinah, Dhahirah and Sharqiyah. It dispatches power from all Centrally Dispatched Generation Stations owned by the following companies: (1). 1. Ghubrah Power Desalination Station 2. Rusail Power Station 3. Wadi Jizzi Power Station 4. Manah Power Station 5. Al Kamil Power Station 6. Barka Power Desalination Station 7. Sohar Power Station The power transmitted by the company is delivered to the following distribution companies, which are licensed to distribute and supply power in a range lower than 132kV voltage (i.e. 66kV, 33kV,11kV and 0.415kV): 1. Muscat Electricity Distribution Company (MEDC) for Muscat area 2. Mazoon Electricity Company (MZEC) for South Batinah, Dakhliyah and Sharqiyah regions 3. Majan Electricity Company (MJEC) for North Batinah and Dhahirah regions Fundamentals of Power Generation and Transmission After the electricity leaves a power generation (1), the voltage is increased at a step-up grid substation (2). Subsequently, the energy travels along a transmission line to the area where the power is needed (3). Once there, the voltage is decreased, or stepped-down, at another primary substation (4), and a distribution power line (5) carries the electricity until it reaches a home or business (8). (1) Fig -1 Electrical Power System (1) Overhead Lines The main components of the HV high voltage power transmission are; the overhead towers, conductors, insulators, lightning arrestors, CVT CT and cable sealing ends. It has been well recognized since the starting of electric power generation that overhead transmission lines (OHL) have represented the most important component for the electric power transmission and distribution. The over head transmission line generally dedicated for high voltage range, while the buried type (underground cables) are commonly used in lower voltage range for the distribution purpose. However, in Oman, both systems are used in various applications depending on the cost, development conditions and topography constraints. OETC has planned, designed and erected overhead power lines for various voltage levels in many parts of the sultanate of Oman. Line voltage Selection According to IEC 60038 there are standard voltage ranges used for the electric power transmission and distribution. The following are the main voltage levels For 3-phase AC power supply: -Low voltage range from 220v up to 1 kV AC Medium voltage range from 1 kV to 36 kV AC High voltage range from 52 kV to 765 kV AC) and higher Generally the Low-voltage transmission and distribution networks serve households and other small business consumers. Networks on the medium-voltage level usually supply larger buildings and settlements, industrial plants and other large consumers; the power supply capacity is typically less than 10 MVA per circuit. The high voltage ranges up to 145 kV are usually used for sub-transmission of the electric power regionally, and also feed the medium-voltage electric network. This level is frequently selected to support the medium-voltage level even when electric power is lower than 10 MVA. Moreover, some of high-voltage transmission lines are also used to transmit the electric power from medium size power plants, like hydro power plants on water streams, channel or rivers, and provide electric power for large-scale units, such as considerable power plants or steel factories. The bandwidth of electrical transported power corresponds to the broad range of utilization, but it rarely exceeds 100 MVA per circuit, while the surge impedance load is 35 MVA (approximately). In most European countries, the high voltage lines of 245 kV were greatly used in interconnection of power supply systems and this before the 420 kV level was brought to this purpose. Nowadays, the usage of 245 kV lines is decreased to some extent due to the availability of the 420 kV transmission network. The 420 kV level represents the highest operation voltage used for AC transmission in Central Europe. It typically interconnects the power supply systems and transmits the energy over long distances. Some 420 kV lines connect the national grids of the individual European countries enabling interconnected network operation (UCTE = Union for the Co-ordination of Transmission of Electricity) throughout Europe. Large power plants such as nuclear stations feed directly into the 420 kV network. The thermal capacity of the 420 kV circuits may reach 2,000 MVA, with a surge impedance load of approximately 600 MVA and a transmission capacity up to 1,200 MVA.[SIEMENS Power Engineering Guide 2 009]11 Selection of conductors and earth wires Electric conductors are the main important part in the overhead power line network and they must be selected carefully for the electric transmission lines because this will ensure economical and reliable transmission and contribute directly to the total line costs. Therefore, to achieve better economic solution, aluminum and its alloys have been used as conducting materials for power lines due to the favorable price, the low weight and the necessity of certain minimum cross-sections. On the other side, aluminum is a very corrosive metal. But when a dense oxide layer is formed it can stop further corrosion. Therefore, up to a certain level, aluminum conductors are well-suited for areas in which corrosion is an issue, such as humid climate in areas located near coastal zone. Generally, there are a number of different designs in use for aluminum conductors. As an advantage, All-aluminum conductors (AAC) have the highest conductivity for a given cross-section; however, they possess relat ively low mechanical strength, which limits their installation to short spans and low tensile forces. To increase the mechanical strength, aluminum wires are made of mixing with other alloys like aluminum-magnesium-silicon alloys. In this way, the strength can be increased approximately twice that of pure aluminum. But practically, all-aluminum and aluminum alloy conductors have exhibited some susceptibility to vibrations. To solve this problem, compound conductors with a steel core, so-called aluminum conductor, steel-reinforced (ACSR), can avoid this disadvantage. The ratio between aluminum and steel ranges from 4.3:1 to 11:1. An aluminum-to-steel ratio of 6.0 or 7.7 provides an economical solution. Conductors with a ratio of 4.3 should be used for lines installed in regions with heavy wind and ice loads. Conductors with a ratio higher than 7.7 provide higher conductivity. But because of lower conductor strength, the sags are bigger, which requires higher towers. Experience has shown that ACSR conductors, just like aluminum and aluminum alloy conductors, provide the most economical solution and offer a life span greater than 40 years. Conductors are selected according to electrical, thermal, mechanical and economic aspects. The electric resistance as a result of the conducting material and its cross-section is the most important feature affecting the voltage drop and the energy losses along the line and, therefore, the transmission costs. The cross-section has to be selected so that the permissible temperatures will not be exceeded during normal operation as well as under short-circuit condition. With increasing cross-section, the line costs increase, while the costs for losses decrease. Depending on the length of the line and the power to be transmitted, a cross-section can be determined that results in the lowest transmission costs. The heat balance of ohmic losses and solar radiation against convection and radiation determines the conductor temperature. A current density of 0.5 to 1.0 A/mm2 based on the aluminum cross-section has proven to be an economical solution in most cases. [SIEMENS Power Engineering Guide 2009] (9) The table below shows the characteristics of AC overhead lines (data refer to a one circuit of a double-circuit line) Table -1 characteristic of AC overhead lines (9) High-voltage results in correspondingly high-voltage gradients at the conductors surface, and in corona-related effects such as visible discharges, radio interference, audible noise and energy losses. When selecting the conductors, the AC voltage gradient has to be limited to values between 15 and 17 kV/cm. Since the sound of the audible noise of DC lines is mainly caused at the positive pole and this sound differs from those of AC lines, the subjective feeling differs as well. Therefore, the maximum surface voltage gradient of DC lines is higher than the gradient for AC lines. A maximum value of 25 kV/cm is recommended. The line voltage and the conductor diameter are one of the main factors that infl uence the surface voltage gradient. In order to keep this gradient below the limit value, the conductor can be divided into subconductors. This results in an equivalent conductor diameter that is bigger than the diameter of a single conductor with the same cross-section. This aspect is important for lines with voltages of 245 kV and above. Therefore, so-called bundle conductors are mainly adopted for extra-high-voltage lines. Table 2.5-2 shows typical conductor configurations for AC lines. From a mechanical point of view, the conductors have to be designed for everyday conditions and for maximum loa ds exerted on the conductor by wind and ice. As a rough figure, an everyday stress of approximately 20 % of the conductor rated tensile stress can be adopted, resulting in a limited risk of conductor damage. The maximum working tensile stress should be limited to approximately 40 % of the rated tensile stress. Earth wires, also called shield wire or earth wire, can protect a line against direct lightning strikes and improve system behavior in the event of short-circuits; therefore, lines with single-phase voltages of 110 kV and above are usually equipped with earth wires. Earth wires made of ACSR conductors with a sufficiently high aluminum cross-section satisfy both requirements. Since the beginning of the 1990s, more and more earth wires for extra-high-voltage overhead power lines have been executed as optical earth wires (OPGW). This type of earth wire combines the functions just described for the typical earth wire with the additional facility for large data transfer capacity vi a optical fi bers that are integrated into the OPGW. Such data transfer is essential for the communication between two converter stations within an HVDC interconnection or for remote controlling of power stations. The OPGW in such a case becomes the major communication link within the interconnection. OPGW are mainly designed in one or more layers of aluminum alloy and/or aluminum-clad steel wires. One-layer designs are used in areas with low keraunic levels (small amount of possible lightning strikes per year) and small short-circuit levels. [SIEMENS Power Engineering Guide 2009](9) Selection of insulators Usually, insulators in the overhead line are subject to electrical and mechanical stresses, because they have to isolate the conductors form potential to earth and must provide physical supports. Therefore, Insulators must be capable of withstanding these stresses under all conditions encountered in a transmission line. Normally, the electrical stresses result from: The steady-state operating power-frequency voltage (highest operation voltage of the system) Temporary over voltages occurred at specific power frequency Switching and lightning over voltages Chapter -2 Introduction Electrical insulators are very critical and important component in the electric power systems such as distribution transmission lines. Previously, the electrical insulators which is made of ceramic and glass materials. But in 1963, a polymeric insulator were developed and its improvements in design and manufacturing in the modern years have made it attractive to utilities. polymeric insulator consists of a fibreglass core rod covered by weather-sheds or skirts of polymer such as silicone rubber, equipped with metal end fittings. It is also called composite insulators, which means made of at least two insulating parts a core and housing equipped with end fittings. Polymeric insulators have many advantages over the ceramic and glass insulators such as good performance in contaminated environment, light weight, easy handling, maintenance free, and considerably low cost etc. Because of these properties it is gaining popularity worldwide and replacing the conventional ceramic and glass insulators in many countries. Therefore, our research shall focus the light on the silicon rubber insulator and the main advantages can be achieved by using such type of electrical insulators. The following is a comparison showing the different factors between ceramic and composite insulators. FACTORS CERAMIC COMPOSITE Resistance to flashovers in Polluted atmosphere. Low High Resistance to puncture Puncturable (Class: B insulators) Not puncturable Resistance to Cracking and Erosion in Polluted atmosphere.

No maintenance is required Weight More 10% to 35% of Ceramic Insulator Resistance to breakage and Vandalism Breakable in Vandalism prone areas Unbreakable Artificial Pollution Test Mandatory Not applicable Power Arc Test Mandatory Not mandatory Table -1 comparison different factors between ceramic and composite insulators (10). Insulator types There are various insulator designs used in different applications, depending on the requirements and the application with certain insulator types: Cap-and-pin insulators (fig.2) are made of porcelain or pre-stressed glass. The individual units are connected by fittings of malleable cast iron or forged iron. The insulating bodies are not puncture-proof, which is the reason for a relatively high number of insulator failures. In Central Europe, long-rod insulators made from aluminous porcelain (fig.3) are most frequently adopted. These insulators are puncture-proof. Failures under operation are extremely rare. Long-rod insulators show superior behavior, especially in polluted areas. Because porcelain is a brittle material, porcelain long-rod insulators should be protected from bending loads by suitable fittings. Composite insulators are the third major type of insulator for overhead power line applications (fig.4). This insulator type provides superior performance and reliability, particularly because of improvements over the last 20 years, and has been in service for more than 30 years. Fig -2 Cap and pin (disc insulator) (9) Fig -3 Long-rod insulator with clevis cap (9) Fig -4 Glass fibre reinforced composite insulator with ball and socket fittings (Lapp insulator) (9) The composite insulator is made of a glass fiber reinforced epoxy rod. The glass fibers applied are ECR glass fibers that are resistant to brittle fracture (ECR = electrical grade corrosion resistant glass fibers). In order to avoid brittle fracture, the glass fiber rod must additionally be sealed very carefully and durably against moisture. This is done by application of silicone rubber. Nowadays, high temperature vulcanized (HTV) silicone is used. The silicone rubber has two functions within this insulator type: Sealing the glass fiber rod Molding into insulator sheds to establish the required insulation Metal fittings are compressed onto the glass fiber rod at both ends of the insulator, either with a ball socket or clevis connection fitting. Since the 1980s, compression fittings have been the prevailing type. The sealing of the area between fitting and silicone housing protecting the rod is most important, and is nowadays done with special silicone elastomer, which offers after vulcanization the characteristic of a sticky solid, similar to a fluid of high viscosity. Advantages of the composite long-rod insulator are: Light weight, less volume and less damages Shorter string length compared to cap-and-pin and porcelain long-rod insulator strings Up to 765 kV AC and 600 kV DC, only one unit of insulator (practical length is only limited by the ability of the production line) is required High mechanical strength Vandalism resistance High performance in polluted areas, based on the hydrophobicity (water repellency) of the silicone rubber Advantages of hydrophobicity are: Silicone rubber offers outstanding hydrophobicity over the long term; most other polymeric housing material will loose this property over time Silicone rubber is able to recover its hydrophobicity after a temporary loss of it The silicone rubber insulator is able to make pollution layers on its surface water-repellent, too (hydrophobicity transfer) Low surface conductivity, even with a polluted surface and very low leakage currents, even under wetted conditions. Insulator string sets Suspension insulator sets carry the conductor weight, including additional loads such as ice and wind, and are arranged more or less vertically. There are I-shaped (fig.5a) and V-shaped sets in use. Tension insulator sets (fig.5b, fig.5c) terminate the conductors and are arranged in the direction of the conductors. They are loaded by the conductor tensile force and have to be rated accordingly. Multiple single, double, triple or more sets handle the mechanical loadings and the design requirements. Fig -5a; I-shaped suspension insulator set for 245 kV (11) T Fig -5b&c; Double tension insulator set for 245 kV (Elevation, Top Plan, bottom) (9) The general electrical layout of insulation is ruled by the voltages to be withstood and the pollution to which the insulation is subjected. The standards IEC 60071-1 and IEC 60071-2 as well as the technical report IEC 60815, which provides four pollution classes, give guidance for the design of the insulation. Because IEC 60815 is applicable to AC lines, it should be noted that the creepage distances recommended are based on the phase-to-phase AC voltage (UL-L). When transferring these creepage distances recommended by IEC 60815 to a DC line, it should be noted that the DC voltage is a pole-to-earth value (UL-E). Therefore, these creepage distances have to be multiplied by the factor à ¢Ã‹â€ Ã… ¡3. Furthermore, it should be noted that the AC voltage value refers to a mean value, while the DC voltage is comparable to a peak value, which requires a further multiplication with factor à ¢Ã‹â€ Ã… ¡2. Insulators under DC voltage operation are subjected to more unfavorable conditions tha n they are under AC, due to a higher collection of surface contamination caused by the constant unidirectional electric field. Therefore, a DC pollution factor has to be applied. Table shown with figure 5a shows specific creepage distances for different insulator materials under AC and DC application, and is based on industry experience published by power supply companies in South Africa and China. The results shown were confirmed by an experienced insulator manufacturer in Germany. The correction factors shown are valid for porcelain insulators only. When taking composite insulators into consideration, an additional reduction factor of 0.75 can be applied. The values for a DC system must be seen as a guideline only, that must be verified on a case-by-case basis for new HVDC projects. To handle switching and lightning overvoltages, the insulator sets have to be designed with respect to insulation coordination according to IEC 60071-1 and IEC 60071-2. These design aspects determine the gap between the earthed fi ttings and the live part. However, for HVDC application, switching impulse levels are of minor important because circuit-breaker operations from AC lines do not occur on DC back-to-back lines. Such lines are controlled via their valve control systems. In order to coordinate the insulation in a proper way, it is recommended to apply and use the same SIL and BIL as is used for the equivalent AC insulation (determined by the arcing distance). [SIEMENS Power Engineering Guide 2009](9) Selection and design of supports Together with the line voltage, the number of circuits (AC) or poles (DC) and type of conductors, the configuration of the circuits poles determines the design of overhead power lines. Additionally, lightning protection by earth wires, the terrain and the available space at the tower sites have to be considered. In densely populated areas like Central Europe, the width of right-of-way and the space for the tower sites are limited. In the case of extra-high-voltages, the conductor configuration affects the electrical characteristics, the electrical and magnetic field and the transmission capacity of the line. Very often there are contradicting requirements, such as a tower height as low as possible and a narrow right-of-way, which can only be met by compromises. The minimum clearance of the conductors depends on the voltage and the conductor sag. In ice-prone areas, conductors should not be arranged vertically, in order to avoid conductor clashing after ice shedding. For low-voltage and medium-voltage lines, horizontal conductor configurations prevail; these configurations feature line post insulators as well as suspension insulators. Poles made of wood, concrete or steel are preferred. Fig.6 shows some typical line configurations. Earth wires are omitted at this voltage level. For high-voltage and extra-high-voltage power lines, a large variety of configurations are available that depend on the number of circuits (AC) or poles (DC) and on local conditions. Due to the very limited right-of-way, more or less all high voltage AC lines in Central Europe comprise at least two circuits. Fig.7 shows a series of typical tower configurations. Arrangement e is called the Danube configuration and is often adopted. It represents a fair compromise with respect to width of right-of-way, tower height and line costs. For AC lines comprising more than two circuits, there are many possibilities for configuring the supports. In the case of circuits with differing voltages, those circuits with the lower voltage should be arranged in the lowermost position (fig7g). DC lines are mechanically designed according to the normal practice for typical AC lines. The differences from AC Line layout are the: Conductor configuration Electric field requirements Insulation design For DC lines, two basic outlines (monopole and bipole), with variations should be considered. Fig.7i-l show examples for HVDC line configurations that are valid for all voltage levels. The arrangements of insulators depend on the application of a support within the line. Suspension towers support the conductors in straight-line sections and at small angles. This tower type offers the lowest costs; special attention should therefore be paid to using this tower type as often as possible. Angle towers have to carry the conductor tensile forces at angle points of the line. The tension insulator sets permanently transfer high forces from the conductors to the supports. Finally, dead-end towers are used at the terminations of a transmission line. They carry the total conductor tensile forces on the line side (even under unbalanced load condition, e.g., when conductors of one tower side are broken) and a reduced tension into the substations (slack span). Fig.6 Configuration of Medium voltage supports Various loading conditions specified in the respective national and international standards have to be met when designing towers. The climatic conditions, the earthquake requirements and other local environmental factors are the next determining factors for the tower design. When designing the support, a number of conditions have to be considered. High wind and ice loads cause the maximum forces to act on suspension towers. In ice-prone areas, unbalanced conductor tensile forces can result in torsional loading. Additionally, special loading conditions are adopted for the purpose of failure containment, that is, to limit the extent of damage. Finally, provisions have to be made for construction and maintenance. Depending on voltage level and the acting forces of the overhead line, differing designs and materials are adopted. Poles made of wood, concrete or steel are very often used for low voltage and medium-voltage lines. Towers with lattice steel design, however, prevail at voltage levels of 110 kV and above (fig.7). Guyed lattice steel structures are used in some parts of the world for high-voltage AC and DC lines. Such design requires a relatively fl at topography and a secure environment where there is no threat from vandalism and theft. Guyed lattice steel structures offer a substantial amount of cost savings with respect to tower weight and foundation quantities. However, a wider right-of-way has to be considered. Foundations for the supports Usually, overhead power line supports are installed on concrete foundations. The foundations have to sustain the overall weight of the tower and should be designed in accordance with the local or international standard applicable for the particular projct. Fig. 7;(a-h) Tower configurations for AC high-voltage lines. (i-l) Tower configurations for DC high-voltage lines The selection of foundation types and the design is decided by the: Total weight resulting from tower Location and Soil conditions Accessibility to the line route Availability of machinery Constraints of the particular country and the site Concrete blocks or concrete piers are in use for poles that exert bending moments on the foundation. For towers with four legs, a foundation is provided for each individual leg. Pad and chimney and concrete block foundations require good bearing soil conditions without groundwater. Driven or augured piles and piers are adopted for low-bearing soil, for sites with bearing soil at a greater depth and for high groundwater level. In case of groundwater, the soil conditions must permit pile driving. Concrete slabs can be used for good bearing soil, when subsoil and groundwater level prohibit pad and chimney foundations as well as piles. Fig. 8; Foundations for four-legged towers Route selection and tower spotting Selection of route and planning represent increasingly difficult tasks, because the right-of-way for transmission lines is limited and many aspects and interests have to be considered. Route selection and approval depend on the statutory conditions and procedures prevailing in the country of the project. Route selection nowadays involves preliminary desktop studies with a variety of route alternatives, environmental impact studies, community communication hearings and acceptance approval from the local authorities.

Sigmund Freud Essay

Sigmund Freud has investigated the Psychoanalytic Theory (1856-1939). This theory caused great inconvenience when delivered and accepted a systematic war because Freud revealed the importance and impact of human sexual impulses stressing that culture is built over their oppression. The Psychology of Conflict is one of the basic principles in the Psychoanalytic theory which sees the function of the mind as the expression of conflicting powers. Some of these forces are conscious but the key is unconscious. This conflict reflects a contradiction in dual nature of someone as a biological and social creature. During the development and socialisation of the individual it is inevitable to experience frustration anger, frustration and conflict / inconsistency (conflict). The Pleasure principle is another basic principle of psychoanalytic theory is that human psychology governed by the tendency of man craves pleasure and avoids the pain. The primary experience pleasure and pain play an import ant role in structuring of human personality. The Freud was first modern psychologist who gave importance to childhood. The sources of the ribs are always beyond the region of the conscious. They repulsed outside the conscious because they have painful character. Another basic principle of the psychoanalytic theory of personality is precisely this topographical perspective. Namely that every mental element judged on how accessible is the conscious. The conscious is only a small piece of psychic resources we have. Another basic principle is determinism. The events that occur in the human mind are not accidental, occasional or disconnected. The thoughts, feelings, impulses coming into consciousness are a chain of causally connected events, associated with some previous experience in life. Several of the links are unconscious. Another key element that sees the psychoanalytic theory. Personality is the dynamic view that that there are sexual sprints instinct of life (life oriented libidinal impulses – EROS) and aggressive momenta death instinct (destructive, death, aggressive impulses – THANATOS) that irritate and cause the mind to work with, act, to change. Because of their biological base these forces have called instincts or impulses (drives). Finally, another principle of psychoanalytic theory of personality is genetic point of view, namely that the birth of contrasts / conflicts, personality traits of neurotic symptoms and general psychological structure of man can be found at major events of childhood that created desires and imaginations. The roots  of psychological structures are born in fantasies and desires of childhood. The human soul consists of three concepts: the ego is the reservoir of mental energy – we are born with it which includes all biological instincts of hunger , thirst, sexual satisfaction, which give strength and direction to human behaviour. The ego begins to evolve after birth and occurs around the 6th month. The role of the ego is to mediate between that of reality, and the superego. That’s why we say that the ego operates on the reality principle and is conscious. The super- ego is the structure of personality that represents the moral principles of society as conveyed in person from their parents – is what we call conscience- and the source of obligations. Apart from the super – conscious ego has another piece of the ego-ideal. The Id and the super- ego are constantly in a fight. When ego cannot find a solution to reconcile the desires of the Id and the super-ego, anxiety is created. Stress is a warning message that ego does not succeed in his role. A group of neo- Freudian psychoanalysts were called ‘analysts of the Ego’ (Karen Horney, Anna Freud, Erik Erikson, etc. ) who gave greater importance to me and less to that . As it’s known, Freud argued that the ego is a mere intermediary that seeks to satisfy the needs and impulses of that without disrupting or to conflict with the superego. But according to analysts of the Ego , the one no longer seen as the superpower of mental structure and I treated like a force that has the ability to control the environment and to choose the time and manner in which satisfy the impulses of the id. The ego is considered capable to create and achieve satisfactory targets chos en by the individual. So between the instinctual drives, external conditions and Act inserted the thought that controls both the internal energy as and reactions of the individual to the external environment. A second new direction influenced psychoanalytic thinking emphasizes the importance of social relationships to explain the formation of personality. So instead of seeing human nature as the result of conflicts around the momenta of him, seeing it more as the result of the child’s relationship with other important people in his life . This direction is reflected in the modern psychoanalytic method called Theory of the relationship with the object or object relations (Object Relations Theory – Melanie Klein, Heinz Kohut). This theory emphasizes the relative adhesion (attachment) of the baby, especially the mother, and the importance of the quality of these early  attachments for the development of the ego of the child, feelings about oneself and developing interpersonal relationships in later life. So theorists of the relationship with the object they see the relationship with parents as an important determinant of the direction taken by the personality of the individual. Apart from these two directions of psychoanalytic thought seeing two of their colleagues nearby Freud, who came into conflict with him, to create their own schools. Jung disagreed with Freud about the nature of the subconscious. Jung believed that the unconscious is not just a reservoir of forbidden impulses and repressed memories, but also the source of our drive for pleasure and creativity. Jung also believed that within us there is a struggle of opposing forces. Every man has a passive – a feminine nature and dynamics â⠂¬â€œ masculine nature. Each one of us also has elements of introversion and extroversion. Also, there is a struggle between the face we present to others (persona) and private self-image (anima / animus). According to Jung, the work of every man is to be able to unite these opposing forces. The Adler disagreed with Freud because he believed that the main force mobilization in human life is not the satisfaction of sexual momenta, but the effort for supremacy. By this meant the interior searching for perfection. Adler said that all children are born with a deep sense of inferiority because of their small size, natural weaknesses and lack of knowledge and power in the world of adults. First used the term inferiority complex. Adler believed that the way parents relate to their children has a significant effect on the child’s ability to overcome these feelings of inferiority and succeed in later life. So Adler saw personality as deeply influenced by the quality of raw social relations. Also important psychoanalytic thought is that Karen Horney saw this adult personality as shaped by childhood experiences, but, unlike Freud, she gave this emphasis on social relationships – especially with parents – instead of solving contradictions of Him . The Horney tal ked about feelings † basic anxiety  » (basic anxiety) and  «basic hostility  » (basic hostility). When parents behave indifferently, derogatory and instability, the child feels insecure and helpless experiencing basic anxiety. These feelings, according to Horney are accompanied by a deeper feeling of resentment towards parents- basic hostility. Because this hostility cannot be expressed directly, because the child needs and fears his parents, repelled and leads to  feelings of worthlessness and anxiety. This tension between basic hostility and basic anxiety leads the child, and later neurotic adult, adopt one of the following 3 stops social interactions; An action towards other, an action against others and an action away from others. When moving towards the other, the person succumbs to others and is always anxious to please them in order to gain approval and love. The person moving against the other is trying to find confidence through domination. The goal of the person who moves away from others is to protect himself, to find safety in the distance, the removal. So he never wants to create close relationships. All these protective mechanisms create many interpersonal problems.
