The National Multiple Sclerosis Society (as cited in Bishop Rumrill, 2015) states that the debilitating disease of multiple sclerosis (MS) impacts 2.3 million individuals around the world. This particular disease is considered chronic and typically worsens in severity over time, leading to an array of diverse symptoms that primarily diminish physical and cognitive abilities (Finlayson, Garcia, Cho, 2008). As a result of these impaired abilities, employment is one of the most prominent areas of daily life impacted (Bishop Rumrill, 2015). Don’t waste time! Our writers will create an original "The Impact of Multiple Sclerosis on Employment" essay for you Create order In fact, McFadden et al. (as cited in Bishop Rumrill, 2015) affirms that merely 20% of individuals with MS maintain their employment positions for 10 years post-diagnosis. This circumstance is troubling for individuals with MS due to the fact that employment is a significant aspect of a prosperous and fulfilling life (Institute of Medicine as cited in Bishop Rumrill, 2015). A thorough examination of the etiology and nature of deviation regarding MS will be conducted to identify how specific impairments are correlated to difficulties with employment maintenance. Etiology and Nature of Deviation MS is categorized as a disease of the central nervous system (CNS) marked by sporadic, repetitive occasions of inflammation (Lee Dunn as cited in Bishop Rumrill, 2015). In the beginning of disease onset, individuals with MS typically experience alternating periods of disease progression and regression (Cameron Klein, 2010). However, as time elapses, some individuals with MS experience an increase in symptom severity as inflammation heightens (Cameron Klein, 2010). The inflammation ultimately engenders demyelination of neuronal axons throughout various areas in the CNS including the brain, spinal cord, and optic nerves (Lee Dunn as cited in Bishop Rumrill, 2015). Myelin is composed of lipids and functions as an axonal covering that promotes enhanced speed and efficiency of electrical impulse conduction (Schapiro as cited in Bishop Rumrill, 2015). When the myelin covering is diminished and damaged through the presence of inflammation, electrical impulses sent between commun icating neurons decelerates (Bishop Rumrill, 2015). As a consequence of this impulse deceleration, the communication of information between neurons loses efficiency and can ultimately obstruct an array of physical, cognitive, sensory, and psychological processes in the body (Schapiro as cited in Bishop Rumrill, 2015). The exact etiology of MS is not factually declared (Bishop Rumrill, 2015). However, biological and environmental components present possible explanations regarding the likelihood of acquiring this disease (Bishop Rumrill, 2015). In addition, the body’s immune system may also contribute to the development of MS (Pakenham as cited in Bishop Rumrill, 2015). Pakenham (as cited in Bishop Rumrill, 2015) states that individuals with MS tend to have immune system responses that trigger T cells to attack the myelin of axons in the CNS. Impairment The symptoms that manifest from MS fluctuate between impacted individuals (Herndon as cited in Bishop Rumrill, 2015). Herndon (as cited in Bishop Rumrill, 2015) explains that the reason for symptom diversity within this population involves the differences in location and severity of the CNS damage. For instance, damage to the frontal and parietal lobes of the brain typically lead to psychological issues, while damage to the brainstem and spinal cord engender diminished physical abilities of the bodily limbs (Fraser, Clemmons, Bennett as cited in Bishop Rumrill, 2015). Two prevalent impairments resulting from MS involve cognitive dysfunction and fatigue (Bishop Rumrill, 2015). Chiaravalloti and DeLuca (as cited in Bishop Rumrill, 2015) state that cognitive dysfunction is found in up to 70% of individuals who suffer from MS. Although the degree and type of cognitive dysfunction differs from person to person, typical problems include challenges with memory recollection, atten tive abilities, and executive skills (Pakenham as cited in Bishop Rumrill, 2015). Fatigue, on the other hand, is present in 92% of individuals with the condition of MS (The Multiple Sclerosis Coalition as cited in Bishop Rumrill, 2015). The Multiple Sclerosis Council for Clinical Practice Guidelines (as cited in Andreasen, Stenager, Dalgas, 2011) explains that the presence of fatigue results in the diminished ability to execute functional activities of daily life. Therefore, individuals with MS who specifically possess cognitive impairments and fatigue struggle to preserve the physical and cognitive abilities required to execute employment duties and maintain occupational positions (Bishop Rumrill, 2015). In addition, these particular individuals face environmental hinderances that cause the maintenance of employment to be challenging to an even greater degree (Duggan, Fagan, Yateman as cited in Bishop Rumrill, 2015). As a result of these impairments, employment positions can be lost (Bishop Rumrill, 2015). This particular circumstance is difficult for this population since employment provides a sense of purpose, leads to essential social engagement, and secures financial means (Institute of Medicine as cited in Bishop Rumrill, 2015). Both cognitive dysfunction and fatigue represent only two out of many MS impairments that can lead to the loss of employment (Bishop Rumrill, 2015). Conclusion The globally-prevalent disease of MS leads to the diminishment of physical and cognitive abilities required to complete daily functional tasks (Finlayson, Garcia, Cho, 2008). As a result of functional limitations, employment becomes challenging for this population to maintain (Bishop Rumrill, 2015). This circumstance ultimately lessens the quality of life present within this particular population, eliminating an essential component of daily routine (Schiavolin et al. as cited in Bishop Rumrill, 2015).

Analysis Of Grace Nichols s The Fat Black Woman s Poem

Explore how one or more text/s critically reconsider representations of the raced and/or gendered body. The title of Grace Nichols’s collection of poem’s ‘The Fat Black Woman’s Poem’s’ portrays three social stereotypes within itself; being fat, being black, and being a woman. These definitions and portrayals of these social stereotypes can often be seen as controversial as Nichols’ poems represent an apparent attempt to challenge conventional white male definitions of black women, and also reinvent the identities of black women in new, unexpected and unfiltered ways. Nichols’s depicts the black female body as an empowering mechanism that can be used to express a person’s individuality and desires. This new depiction of the body that Nichols’ portrays emerges as an active medium that is constantly changing through various acts and diverse meanings as opposed to being signified by fixed cultural conventions. Nichols’ manages to represent the female body as an almost battleground between the forces of patriarchal control and feminine resistance. Nichols’ theme of female liberation can be seen to coincide with the views of French feminist theorists such as Julia Kristeva, Luce Irigaray and Hà ©là ¨ne Cixous. Nichols explores and celebrates various aspects of female identity and sexuality through the description and liberation of the female body.

Paragraph1: Why were tension and excitement created? Mercutio is not in a good mood but he is in argumentative mood, he seems angry. The audience is prepared for the fact that a fight is going to occur (tension and suspense are built). He tells Mercutio that if someone is in a bad mood, everything even an unimportant cause will end to a fight. Benvolio is warning Mercutio that because it is a hot day he is sure there will be a fight (and if we meet we shall not scape a brawl-Benvolio). He suggests Mercutio that they should go home. The strong use of vocabulary and personification here increases the tension. for now, these hot days, is the mad blood stirring, Benvolio). We know that a fight is inevitable.

Virtualisation Benefits and Challenges

Question: Discuss about the Virtualisation for Benefits and Challenges. Answer: Introduction: Liberty Wines biggest peril with regards the installed IT system was that it lacked the competency to meet with the increasing business. So much that the staff of the company were unable to respond within the stipulated time frame to the queries raised by the customers. The company is losing its clients because of the old IT system which is incapable of supporting the expansion of the business. Due to this it is affecting the companys competitive advantage. Server virtualisation had benefited Liberty Wines both in the business as well as the environment. With regards the latter the company was able to reduce the impact of the carbon foot print by 60 percent. Simply because the usage of the power got reduced substantially as well as the power usage also declined overall. Secondly, since virtualisation led to reduction of servers from ten to less than half i.e. three with an additional back-up server, the cost of office space and other fixed overhead expenditure also lowered. Further since there was a back-up server, the company was secured in case the main server created a problem (ISACA. 2010). The bureau FinCen was not caable enough to fight the various financial crimes taking place in USA prior to 2008 on time simply because the IT system installed was very old unable to support the increasing volume of data accumulation process and its analysis. It was also dependent upon offline system rather than switching to real time system which led to delay in processing and sharing of valuable facts and figures about a particular crime taking place. FinCen needs to upgrade its IT system which would even have the capacity to perform analytical tasks as well. Upgradation of its present system will ensure that the data and valuable information are processed without any loss of substantial time. The bureau launches a FinCen Query Web based App which is a search tool having the capacity to provide real time accessibility to 11 years data of BSA. Financial intelligence is places its reliance upon booming examination of the facts and figures which help in keeping a track of the various illegal activities and thus disrupting the same before it causes any harm. Due to same, FinCen has gained its importance in protecting the national security of a country. It ensures that all the illicit movements of terrorism and money laundering are traced well on time so that the nation is safe from any untoward consequences (Carozza, 2009). One of the reward winning financial crime that was found and disrupted as well by an associate of FinCen was the analysis of huge data by Ann Martin which highlighted the kind of illegitimate act hat was being undertaken between Mexico and USA. She made the crime come to surface about how the money of illegal money of USA was being converted from black to white with the help of some unscrupulous individuals of Mexico. The government appreciated the efforts of Ann (Partnership for Public Service. 2011). However, Ann confesses that the same was possible simply because of the enhanced IT system installed in the bureau which aided her to achieve goal successfully. References: Carozza,D. (2009).

War in vieques Essay Example For Students

War in vieques Essay Why is the US Navy at Vieques, Puerto Rico? Puerto Rico: From Spanish Colony to American Military Bastion After 400 years of Spanish colonial rule, Puerto Rico became a possession of the United States as a direct result of the Spanish-American War of 1898. Right after the invasion the US established a military government, which lasted up to 1900; thereafter, the Foraker Act of 1900 authorized the President of the United States to appoint a civilian governor. In 1917 the Jones Act granted US citizenship to all island residents. In 1948 Puerto Ricans were allowed to elect their own home-grown governor for the very first time. Today, after 101 years of direct economic, political and military rule, Puerto Rico continues to be a US colony. Given its geographical position, Puerto Rico has always played a key strategic military role for the United States. Expropriation of Land for Regional Military Purposes In 1938 the US Navy began using the island-municipality of Vieques, right off the ea stern coast of Puerto Rico, for military practices. In 1941, during the height of WW II, the Navy initiated a campaign of forced expropriation of territory, which ultimately ended in their possession of over two thirds of the island’s most arable land, thereby displacing thousands of families and seriously jeopardizing their basic means of subsistence. The Navy arbitrarily set the price for the expropriated land giving the island residents very little say, if any, in the matter. Resistance became an exercise in futility, for the Navy issued the following ultimatum: Either you accept the price set by the Navy or prepare to be evicted, by force, if necessary, within 24 hours. The net effect of these policies was the clustering of the entire civilian population of Vieques into a small strip of land right in the middle of the island. Thus the US Navy took control of over 75% of this tiny island. 2. Legacy of the US Navy in Vieques: Economic Stagnation Vieques has a population of approximately 9,400 inhabitants. It has an unemployment rate of almost fifty percent (50%) by most conservative estimates. General Electric, which is one of the few large companies in Vieques, will end its operations this summer. Fishing is the only industry in the island of Vieques with any truly viable economic significance. This is obviously due to the Navy’s expropriation of the most fertile lands in the island that formerly sustained a respectable agricultural activity. Carlos Zenn, the former President of the Fishermen Association, said that when the US Navy ships enter the one-hundred-foot deep waters where the fishermen have their traps, â€Å"the ships’ propellers destroy the buoys that indicate where the traps are.† When that happens it is hard for them to find the nets. As a result, the nets stay at the bottom of the sea for eight or twelve months, attracting many fish that ultimately die in the traps. The US Department of Agriculture conducted a stud y of these traps and found that a single net collects from 4,500 to 5,000 pounds of fish in ten months, which poses a severe environmental threat to the fragile marine ecosystem in that region. In 1977, for example, the US Navy destroyed 131 traps. Ecological Damage The immediate effects of the bombings in Vieques are the destruction of delicate ecosystems in the island, which supports hundreds of species of plants and animals that are killed instantly upon the direct impact of the projectiles during military target practices. Furthermore, these bombings and military maneuvers lead to serious contamination of the environment due to toxic residues. In an article published in 1988, engineer and environmental consultant Rafael Cruz-Prez identified three ways in which the militarys bombings pollutes the environment in Vieques: (1) Chemicals in the Missiles’ explosive payloads, (2) Dust and rock particles released into the air as a result of the impact and/or explosion of missiles , and (3) Metallic residues left by missiles after they detonate, and the junk and scrap heap they use for target practice. According to information provided by the Navy, this material is never removed†¦Under the effects of additional explosions and sea breezes, metals are oxidized or decomposed, turning in accelerated fashion into leachates that pollute the environment, said Cruz-Prez in his article. He also referred to a scientific study by the Navy, which says that the sources of drinking water in Vieques Isabel Segunda village and Barrio Esperanza are polluted with toxic chemicals, like TNT, tetryl and RDX. Cruz-Prez commented that the study doesnt explain how these substances got to the water sources, located more than fourteen kilometers away from the shooting area. In the 70s, the US Environmental Protection Agency sampled Vieques air and soil. After studying the samples, the EPA determined that the air has unhealthy levels of particulate matter and the ground has iron l evels above normal. High Levels of Cancer Health Problems The people of Vieques suffer from high levels of cancer and other serious health problems. Studies carried out by the Puerto Rico Department of Health have shown that from 1985 to 1989 the rate of cancer in Vieques rose to 26 percent above the rest of PR. Rafael Rivera-Castao, a retired professor from the University of Puerto Ricos Medical Sciences Campus, has documented an increase in extremely rare diseases, like, for example, Scleroderma, lupus, thyroid deficiencies, and not-so-rare ones, like asthma, which is significantly affecting Vieques’ children. How can the children of Vieques get asthma if this is such a small island? The winds that blow in from the ocean are rich in iodine, which prevents asthma. The only possible cause is air pollution. We dont have factories here, the only source of air pollution here is the Navy, he has stated. 3. Struggle and Resistance The Struggle between David and Goliath Viequesâ⠂¬â„¢ fishermen are extremely courageous. They have confronted the warships at sea several times. In February of 1978, US admiral Robert Fanagan told the fisherman that they would not be allowed to fish during 3 weeks. All NATO countries had planned an intensive military maneuver along all of Vieques’ coastsline. Carlo Zenn informed him that they would protest. â€Å"Imagine me, a Puerto Rican fisherman, telling a US Navy admiral that we’re going to cause problems for them† he said. On February 6, 1978, fed-up with the Navy’s arrogance, the fishermen of Vieques took a desperate gamble. Forty fishing boats ‘invaded’ waters where target practice with live ammunition were about to begin. They were carrying out a struggle with the sling shot of David against the Goliath of NATO. They were successful detaining the maneuvers and awakening the support of the entire Puerto Rican nation. This activism at sea has won important victories for the people of Vieques during their struggle against the US Navy. Mount David After David Sanes Rodrguez’s death on April 19th, 1999, a group of civilians gathered in the area of the â€Å"accident† to protest the bombardments. This show of outrage and civil disobedience is a direct frontal challenge to the US Navy’s ill-gotten authority. On April 21st a group of 15 boats gathered at the place of the bombings, placed a large cross and named the area Mount David-in memory of Mr. Sanes. Mount David is a very dangerous place peppered with live ammunition on the ground. In spite of the this great dangers many people have organized protests behind the gates of the Navy’s restricted areas. All these protests have successfully detained the bombings since Sanes’ death. I know that there is a great danger said Pablo Connelly, one of the civilians protesting at Mount David. He adds: I know that the risks are great, but all the risks are worth it. I do this for my childr en and for the children of all Viequenses and I know that during the time that I remain here there is not going to fall a single bomb in Vieques.† .ud50d532e1f9cd11d9cfee8997adb36d1 , .ud50d532e1f9cd11d9cfee8997adb36d1 .postImageUrl , .ud50d532e1f9cd11d9cfee8997adb36d1 .centered-text-area { min-height: 80px; position: relative; } .ud50d532e1f9cd11d9cfee8997adb36d1 , .ud50d532e1f9cd11d9cfee8997adb36d1:hover , .ud50d532e1f9cd11d9cfee8997adb36d1:visited , .ud50d532e1f9cd11d9cfee8997adb36d1:active { border:0!important; } .ud50d532e1f9cd11d9cfee8997adb36d1 .clearfix:after { content: ""; display: table; clear: both; } .ud50d532e1f9cd11d9cfee8997adb36d1 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ud50d532e1f9cd11d9cfee8997adb36d1:active , .ud50d532e1f9cd11d9cfee8997adb36d1:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ud50d532e1f9cd11d9cfee8997adb36d1 .centered-text-area { width: 100%; position: relative ; } .ud50d532e1f9cd11d9cfee8997adb36d1 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ud50d532e1f9cd11d9cfee8997adb36d1 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ud50d532e1f9cd11d9cfee8997adb36d1 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ud50d532e1f9cd11d9cfee8997adb36d1:hover .ctaButton { background-color: #34495E!important; } .ud50d532e1f9cd11d9cfee8997adb36d1 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ud50d532e1f9cd11d9cfee8997adb36d1 .ud50d532e1f9cd11d9cfee8997adb36d1-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ud50d532e1f9cd11d9cfee8997adb36d1:after { content: ""; display: block; clear: both; } READ: Daily Life In Rome Essay We will write a custom essay on War in vieques specifically for you for only $16.38 $13.9/page Order now

Definition of Descent With Modification

Definition of Descent With Modification Descent with modification refers to the passing on of traits from parent organisms to their offspring. This passing on of traits is known as heredity, and the basic unit of heredity is the gene. Genes are the blueprints for making an organism, and, as such, hold information about its every conceivable aspect: its growth, development, behavior, appearance, physiology, and reproduction. Heredity and Evolution According to Charles Darwin, all species descended from only a few lifeforms that had been modified over time. This descent with modification, as he called it, forms the backbone of his Theory of Evolution, which posits that the development of new types of organisms from preexisting types of organisms over time is how certain species evolve. How It Works The passing on of genes is not always exact. Parts of the blueprints may be copied incorrectly, or in the case of organisms that undergo sexual reproduction, genes of one parent are combined with the genes of another parent organism. That is why children are not exact carbon copies of either of their parents. There are three basic concepts that are helpful in clarifying how descent with modification works: Genetic mutationIndividual (or natural) selectionEvolution of the population (or species as a whole) It is important to understand that genes and individuals do not evolve, only populations as a whole evolve. The process looks like this: Genes mutate and those mutations have consequences for the individuals within a species. Those individuals either thrive or die out due to their genetics. As a result, populations change (evolve) over time. Clarifying Natural Selection Many students confuse natural selection with descent with modification, so its worth repeating, and further clarifying, that natural selection is part of the process of evolution, but not the process itself. Natural selection comes into play, according to Darwin, when a species as a whole adapts to its environment, thanks to its specific genetic makeup. Say at some point in time two species of wolves lived in the Arctic: those with short, thin fur and those with long, thick fur. Those wolves with long, thick fur were genetically capable of living in the cold. Those with short, thin fur were not. Therefore, those wolves whose genetics allowed them to live successfully in their environment lived longer, bred more frequently, and passed on their genetics. They were naturally selected to thrive. Those wolves who were not genetically adapted to the cold eventually died out. Furthermore, natural selection doesnt create variation or give rise to new genetic traits- it selects for the genes already present in a population. In other words, the Arctic environment in which our wolves lived did not prompt a series of genetic traits that didnt already live in certain of the wolf individuals. New genetic strains are added to a population through mutation and horizontal gene transmission- e.g., the mechanism by which bacteria become immune to certain antibiotics- not natural selection. For instance, a bacterium inherits a gene for antibiotic resistance and therefore has a greater chance of survival. Natural selection then spreads that resistance through the population, forcing scientists to come up with a new antibiotic.

Ten Critical Steps for Risk Managers Essay Example | Topics and Well Written Essays - 750 words - 2

Ten Critical Steps for Risk Managers - Essay Example Argentina is one of the Latin American countries which have a high political risks associated with international business. These risks affect the way international business is done between Argentina and the rest of the world.According to World Bank (2001), managing political risk and other forms of risks associated with international business is something that can be very difficult for businesses. However, experts such as Thomas Cook (2012) have provided useful information regarding the ways in which international businesses can address these issues. For a country such as Argentina, the main issue for international business people to understand is the fact that this country is not stable politically. Countries which have not matured democratically such as Argentina have more and higher political risk and it is necessary for businesses to be able to address these risks in a more serious way. The following ten steps as developed by Cook can be used to manage political risk in Argentina . The first issue to for a manager to consider is selecting a risk insurance firm which is suited to the insurance needs of the business. According to Cook (2012), it is absolutely necessary for a manager to know that the underwriters who they choose are conversant in political risks in the country. In this regard, choosing an insurance broker in Argentina will concentrate on looking for an insurance broker who critically understands the political risks in the country not only in theory but also in practice.... In buying insurance, it is always necessary to understand the nature and extent of the risk involved (Cook, 2012). In this regard, it will be increasingly necessary to understand the political risks involved in Argentina and then look for an insurance provider who will guarantee these risks. It will be necessary to look for an insurance provider who clearly understands these risks and who is able to look at the way in which the business can be shielded from this kind of risk. Thirdly, the manager should consider combining risk and covering them with one insurance policy. There are a number of risks associated with doing international business in Argentina and this will require combining risks when buying an insurance policy. In this regard, it will be necessary to understand the various risks which can be combined in order to make sure that the business is well protected. For instance, apart from political risks, there are other non-political risks which must be looked at in this reg ard, instead of having a different policy for each risk; it could be useful to have one umbrella policy which will protect the business from all the risks. Fourth, constant communication about the contract after it has been put in place is also very important. This is because Argentina’s political environment is very volatile and therefore the nature and extent of political risks in Argentina keep changing over time. Fifthly, constant review and update of the insurance contract is necessary because political risks can change with regard to which regime is in power and also depending on seasons such as the electioneering season. With a country which does not have a concrete public policy, the nature of the governance is purely

Detroit Bankruptcy Essay Example | Topics and Well Written Essays - 1250 words

Detroit Bankruptcy - Essay Example The announcement of bankruptcy by Detroit is a prophesied case. The liquidation of a municipal’s assets cannot happen as a result of the request of a creditor. A municipality is under the state’s jurisdiction as it is defined by the state. The 10th Amendment of the4 American constitution reserves any power not defined by the constitution for the state. Declaration of bankruptcy rulings ate made in U.S. Bankruptcy courts under federal jurisdiction Many factors have indicated reduced financial activity in the city. The population of the city dropped from a 1.5 million figure in the city’s peak in the fifties to a current size of around 700,000 leaving the city a shadow of itself with tens of thousands of abandoned buildings ("How Detroit went broke - Economics - AEI"). This coupled with the deindustrialization of the city have largely affected the collection of the revenues in the city. However, the major contributor of the state of the city is the accounting of th e funds of the municipality. Legacy costs These are the bills of the municipality in the form of public employee pensions, healthcare, and other post employment benefits. The Government Accounting Standards Board (GASB) in 2006 required all local governments to report publicly OPEB liabilities but did not require the funding of the shortfalls of the OPEB liabilities (John Macomber). The city of Detroit uses 43% of the entire annual city revenue in making payments of this kind. This leaves only, 57% to run the city and cover the wage bill. In the last few decades, the percentage of the city’s revenue used in the settling of these bills has been on the rise with an estimation claiming the percentage will reach 65% in four years. These unfunded liabilities of the Detroit city funds have acted as a weight pulling down the city finances (How Detroit went broke). Half of the $18 billion debt is accounted in public employee retirement benefits, which are not funded. In 2012, the cit y spent $145 million on retiree health care benefits, which is greater by more than half of the $99 million used in 2000 ("How Detroit went broke - Economics - AEI"). The accounting methods relied in the evaluation of the finances of pensions of public employees allows rates of return that are overly optimistic on the supposed riskless pension to be assumed (How Detroit went broke). These also make it possible for the employer in the form of the city of Detroit, to contribute annual contributions that fall short of the required amount. These transform the guaranteed benefits such as pensions, into risky ones. The cause effect of these is a pension liability at a $3.5 billion level when appropriate accounting methods are used which is over 5 times the liability under the city’s accounting methods (John Macomber). This is not helped by the ratio of employees to retirees receiving pension, which stands at 2:1. Increased taxes After the post-war manufacturing and expansion, the c ity started losing revenue because of the high population decrease rates. In response, the city changed its accounting policies and imposed a 1% income tax on all corporations, residents, and non-residents. This aimed to cover the loss in revenues and maintain the city budget (How Detroit went broke). Over the years, the tax rate has been on the rise with the resident income tax doubling only six years after its establishment. A new utility tax came into being in 1971 aiming to maintain the services offered by the city as well as

Introduction to Health and Culture Essay Example | Topics and Well Written Essays - 500 words

Introduction to Health and Culture - Essay Example The Navajo people value their words as much as they value life because they believe that the words they utter will have a deeper impact on how their lives will go. They do not give out words easily and more often than not, other people find themselves waiting for 30 seconds or more just to hear what a member of the Navajo tribe has to say. And more often than not, this characteristic result to conflict or misunderstanding due to the fact that not all who converse with the Navajo people understands or even knows this trait. The doctors and other medical staffs, who have also graduated with a secret degree on Tact and Diplomacy together with their medical degree, are imbedded with deeper understanding and vast knowledge as to how to deal with different kinds of people. Treating a person from a different culture and with a different background is not prioritized in this aspect. As a person with a mission, healing people is the main goal. Doesn't matter who your patients are, what they a re and where they come from; as long as the service given is fair and just, the mission has been served well. Navajo people are also afraid of death; Also the same with everyone all over the world. That doesn't make them ignorant or simple.

Mark Ratners Concepts of Molecular Electronics

Mark Ratners Concepts of Molecular Electronics Mark Ratner  and  The Basis of the Future: Molecular Electronics Levent BahadÄ ±rhan KarakuÃ…Å ¸ 2. Introduction Mark Ratner, He is professor of chemistry and professor of materials science and engineering at Northwestern University. He studies the theory of fundamental chemical processes related to nanoscale application. Ratner is a member of the Internatioanal Academy of Quantum Molecular Science also, His lectures subjects were â€Å"Transport in molecular Junctions†and â€Å"Nano and Energy† at Stanfort University at 2009. I choose Mark Ratner because, Topic of Nano technology and energy generation are important on the sustainable energy. High capaticy batteries, high technology solar cells, etc. besides; new tech-power plants or storages These topics to be studied for me. In short, Quantum mechanics and Nano technology are always interested me[20]. 2.1. Education He graduated from Harvard University department of chemistry at 1964. Then, He started Ph.D. in chemistry from Nortwestern University and working with G. Ludwig hofaker. Ratner first lecture chemistry at New York University from 1970 until 1974[20] 2.2. Career Development He worked may extended period of time in israel and he worked with lots of scientists, including form Tel Aviv University and University of Jesursalem. Also Rater works international association, particularly in Netherlands and Denmark[20] 3. Fields 3.1 Molecular Electronics (Primary field) Molecular electronics increased interest in as of late, induced spawning by information technology may reach it computability limits in a several years. [1-2]. In order to molecular electronics to become a valued alternative to silicon researces, It will not be enough to generated molecular electronic devices with distinguished characteristics, but proper circuit and architectural solution will be needed. When lots of effort has given to the demonstration of electronic functionalities of one molecules and organic filmsi research at the circuit and system level is still in its beginning[5-9]. Investigation on single molecules or nanotube based devices prospect to keep Moore’s law alive once miniaturisation of silicon-based structures becomes useless. As first proposed by Aviram and Ratner [10]. One can imagine to squeeze whole nonlinear circuit elements such as transistors or diodes into single molecules. In principle, suchlike devices could be importantly faster and smaller th an end of the routemap solid state electron devices[11]. 3.1.1 Why molecular electronics? Intrinsically entire electronic processes in nature, from photosynthesis to signal transduction, occur in molecular structures. For electronic epplications, molecular structure have four major advantages: Size: The size scale of molecules is between 1 and 100nm, a scale that permits functional nano-structures with attendant advantages in efficiency, cost and power dissipation. Assembly and recognition: One can exploit secific internolcular interaction to from structures with nano-scale self assembly. Molecular recognition can be used to chance electronic attitutde, providing both swithing and sensing capabilities on the one molecule scale. Dynamical stereochemistry: lots of molecules gave multiple distinct stable conformations or isomers. Such geometric isomers can gave distinct optical and electronic properties. For instance, the retinal one switches between more than one stable structures, a process that transduces light into a chemoelectrical pulse and allows vision. Synthetic tailorability: with choice of character and geometry, ona can extensively vary a transport of the molecule, binding, structural and optical properties. The instrument of molecular synthesis are extremely developed.[12] [http://www.nanowerk.com/nanotechnology/reports/reportpdf/report52.pdf] 3.1.2 Electrode The molecule electrode interface is a severely significant component of a molecular junction. It might limit current flow or completely modify the measured electrical response of the junction. Lots of experimental platforms for constructiong molecular electronic devices are founded on practical comsideration. This approach is in numerous ways the boon and the disaster of the field. For instance, the sulfur gold bond is a fabulous chemical hangle for forming self assembled, forceful organic monolayers on metal surfaces. Other technics such as using a scanning probe tip a cÄ ±ntact the molecule are frequently employed in part. Becuse that avoid processing steps that can damage or unexpecteably modify the molecular component. Optimally the couice of electrode materials would be based not on the easy of production or measurement, but rather on first principles considerations of molecule electrode interactions. On the other hand, in state of the art for the theory of molecule electrode interfaces is very elemantary. [http://www.nanowerk.com/nanotechnology/reports/reportpdf/report52.pdf] 3.1.3 DNA Consider a protein that spans a cell membrane and shuttles information across that membrane. The protein self assembles and self orients in the membrane; it also might switch between two forms, only one of that will transmit the chemicalsignal. Proteins are big molecues and indeed a specific molecular size is required to achieve such a rich combination of properties. The rotaxane molecule shown large and comples, but it is indeed efficiently and small designed, given the set of mechanical, chemical, and electronic properties that have been built into it[16]. Quite likely, transport in DNA junctions will show that the molecule or at least naturally occuring DNA is actually a wide bandgap semiconductor characterized by localized hole hopping between the low energy guanine cytosine pairs. Also guanin yields the most stable positive ion. Because the band gap is wide, DNA seems colourless and long range coherent charge motion is improbable[17]. 3.1.4 Circuit Architecture The potential of chemical synthesis to design specific and maybe even useful device behaviors is rapidly being realised. The following question, what sorts of circuit architectures can most take advantage of molecular electronics, is nowadays receiving rather a bit of attention both from computer scientists and from researchers; progress towerd indentifying and constructing working molecular electronics circutry has advanced fastly[13]. 3.1.5 The Future The primary challenges of realizing a true molecular electronics technology are wintry. Controlled fabriaction to within specified tolerances and its expermental verification is a exclusive problem. Self assembly schemes based on molecular recognition will be viral for that work. Absolutely reproducible measurments of junction conductance are only beginning in laboratories at Cornell, Harvard, Delft, Purdue and karlsruhe Universities and at the Naval research laboratory and same centers. A lot of the technology targets of molecular electronics, such as the computational applications duscussed, should perhaps be viewed as drivers for steering the field forward and for defining the critical and rate limiting challenges that must be overcome[14]. 3.2 Electron transport in molecular wire junctions Molecular conductance junction are structures in that unimolecules or minor groups of molecules conduct electrical current between one than one electrodes In such junctions, the linkage between the molecule and the electrodes very affects the current boltage characteristics. Considering theoretical and several experimental advances, including the understanding of basic systems, there is still limited correspondence between theoretical and experimental studies of these systems[18]. 3.3 Mesoscopic features of charge Generation in organic semiconductors Over the past twenty years, organic materials gave been extremly investigated by countless research groups for implementation in organic photo voltaic(OPV) devices. The organic semi conductors is protrusive by their potential low cost and facile tunability, making organic photovoltaic devices a knowledfe gap in our common understanding of materials, so boyh the time scale and lenght scale (fento to microsecond and nano to micrometer) proper to OPV functionality occupy a challenging a impressive space between the traditional regimes of quantum mechanics and solid state physics[19]. 4. Conclusion Ratner lead up lots of field, research centre and laboratories foremost; International Business Machines (IBM) and The defense Advanced Research Projects Agency (DARPA). Also, He described his experiences as an organizing member; a member of the board of directors and being on steering and selectrion committee. The significance of gaving a staff at research centre and proposal some thoughts on the future nanotechnology. Once for all, Ratner have a part in many today’s technology References [1] J. R.

Basketball Essay -- essays research papers

WHY THE NBA DREAM IS RUINING COLLEGE BASKETBALL   Ã‚  Ã‚  Ã‚  Ã‚  The National Basketball Association is a corporate powerhouse with installments in nearly every major city in the United States. With the exception of European soccer, professional basketball generates more money per season than any other sport in the world. NBA superstars carry as much authority in the entertainment business as the most popular actors, comedians, and musicians. Even the guys who are last off the bench are making more money in one season than the average middle-class worker makes in five years. Corporate America sells its images, logos, slogans, ideas, and viable goods by employing NBA stars to speak publicly on-behalf of their materials. More and more NBA players are showing up in commercials, in magazine ads, on billboards, and in movies. They have their own radio talk shows, their own clothing and shoe lines, their own video games, and even their own restaurants. Essentially, turning pro opens the door to a lifestyle of undeniable prestige, com fort, and public adornment. NBA players can commit the harshest of criminal violations and get off with minimal penalties. NBA players can have just about any woman they want! Enough said. Thankfully, it takes an incredible amount of skill and determination to make it as a professional basketball player. In the last twenty-five years only a handful of high-school athletes have skipped college and gone straight to the big show. Some of these young men built enduring careers and some were washed out before they reached the legal drinking age of 21. Some made it to the hall-of-fame and some remain in the hall-of-shame. Nevertheless, in the past five years there has been an upsurge in the number of high-school athletes who have chosen to forego college and enter the draft. Debate and discussion over this topic as been heated as of late. College coaches argue against professional coaches, writers and reporters argue against sporting agents and advertising executives, and parents squabble with their blue-chip prospects. Supporters of this trend say high-school athletes have the right to select their own path, while their opponents argue that high-school athletes miss-out on a remarkable education opportunity by overlooking the college experience. Clearly, the NBA has no intention of preventing high-school athletes from enterin... ...all. The level of play at the highest level should not suffer because young guys do not know the ins and outs of the game. They should also put a pay-cap on the potential salaries of such under-aged athletes, and agents should be completely removed from the decision making process. None of these things will ever happen though because the NBA makes too much money off its young stars. Sports marketing is already a multimillion dollar business, and agents continue to claw into middle school gyms across the country looking for the next Kobi or Kwame. Moreover, with a game that continues to evolve around its new talent each year, raw flair draws in sponsors, advertisers, and marketers. The public loves to see the young versus the old, and the NBA loves to make money off these kind of situations. So long as colleges are not paying their athletes, which many do in forms of scholarships and performance incentives, college basketball will continue to lose its battle against the NBAâ€℠¢s appeal to young athletes. In this society education is no longer the most rewarding stable of success, instead it’s how many rings you have on your finger and how many video games you have named in your honor.

Emily Dickinson’s Success is Counted Sweetest Essay

Emily Dickinson’s â€Å"Success is Counted Sweetest† has been penned in iambic trimeter with the exception of the first two lines of the second stanza. The poem highlights aphoristic truths that are universal. In the first stanza, Emily Dickinson endeavors to define the true essence of success. The general impression is that success can be ‘counted’ by only those who have experienced it numerous times. Nevertheless, it is more precisely evaluated or counted by those who have never succeeded as they can apprehend its true value. In another poem, â€Å"I Had Been Hungry, All the Years†, Emily Dickinson writes that â€Å"Hunger-was a way / Of Persons outside Windows- / The Entering-takes away-â€Å". For the true experience of life, failures are inevitable. For, what we learn from our failures, success can never teach us. The alliteration with the repetition of the ‘s’ sound lays emphasis on ‘success’. Success also tastes sweeter to the person who has persevered very hard for it, than to a person who has found success effortlessly. The former is also more thankful to God, and cherishes his accomplishment. The word ‘nectar’ here implies water. However, it is perception that renders it ‘nectar’. To the thirsty ones with parched throats, a drop of water tastes as sweet as nectar. Here ‘sorest’ is utilized with reference to its old meaning ,that is ‘greatest’.Only the one in the direst need, can treasure any sort of sanction. Not one of all the purple host Who took the flag to-day Can tell the definition, So clear, of victory! Some people define success by virtue of positions that they acquire and assume in life. The poetess asserts how none of the purple leaders who took the flag to-day could describe what victory actually meant. The act of victory in such a stance of winning a battle is limited to the act of taking away a flag. It also points to the worldly act of hoisting a flag. Arundhati Roy in â€Å"The End of Imagination† toys with the word ‘successful’.She echoes how the meaning of the word ‘successful’ depends upon perception. For instance,a soldier who dies at war is deemed by others to be ‘unsuccessful’.Roy points out that it does not necassarily mean that the soldier is in any way ‘unfulfilled’. The poetess highlights the word ‘to-day’ to underline the presentness and transiency of the situation. ‘Purple’ is the colour of royalty because the fine clothes/robes of kings and emperors were dyed purple; and also connotes ‘blood’. It was the trend that dynasties ruled over some countries .Being born to a royal family, one could never realize how difficult it was to achieve that position as it naturally came to them as a heirloom .Shakespeare said: Some are born great, some achieve greatness, and some have greatness thrust upon ’em. (Twelfth Night Quote Act ii. Scene 5.)Of these,only those who achieve it comprehend its worth according to Dickinson. As he, defeated, dying, On whose forbidden ear The distant strains of triumph Burst agonized and clear! In the above lines, the poetess exemplifies the frenzy of success, that one loses consciousness in. He loses the ability to evaluate himself objectively. In such a context, the person who loses the battle and is dying can perceive it better. The dying man’s ears are not ‘forbidden’. The figure of speech utilized here is a’ transferred epithet’ .Rather what is forbidden to his ears is the sound of success, as he belonged to the defeated side. He is successful in that he can realize the futility of war, and the meaningless of success as the speaker in Wilfred Owen’s â€Å"Strange Meeting’ does. The word ‘strain’ in â€Å"strains of triumphs’ may be used as a pun in the above phrase. Here,the victory may also be ‘strained’. The idea of distance and defeat is suggested by the alliteration of the ‘d’ sound. Moreover, the one who is caught in the noise and fury of success cannot ,in fact hear its sound. The one who serenely lies away can perceive it better. It does not manifest itself subtly, but does† Burst agonized and clear!† Rukhaya, M. (2012, October 07).

Gratitude Quotes That Come Straight From the Heart

Gratitude Quotes That Come Straight From the Heart Jean Baptiste Massieu, the famous deaf educator, made a statement that is now considered a French proverb. He said, Gratitude is the memory of the heart. Indeed, appreciation comes when you feel grateful from the depths of your heart. The head keeps an account of all the benefits you received and gave. But the heart records the feelings of appreciation, humility, and generosity that one feels when someone showers you with kindness. In addition, gratitude and empathy are some of the attitudes that can help you achieve happiness, according to five psychology studies that can help restore your faith in humanity.   Express Gratitude at Every Opportunity Even a small act of kindness deserves a thanks. You cannot weigh the nobility of the act against intentions to decide whether or not to show your gratitude. So what if your friend helped you get a job only because he wanted you to return the favor? So what if you think that he could have helped you get a better job? It is your moral obligation to express gratitude. In the words of Alfred Painter, saying thank you is more than good manners. It is good spirituality. Ralph Marston Make it a habit to tell people thank you. To express your appreciation sincerely and without the expectation of anything in return. Truly appreciate those around you, and you’ll soon find many others around you. Truly appreciate life, and you’ll find that you have more of it. Maya Angelou I want to thank you, Lord, for life and all that’s in it. Thank you for the day and for the hour, and the minute. Toni Mont To say thank you is in recognition of humanity. Joseph Adisson Gratitude is the best attitude. There is not a more pleasing exercise of the mind than gratitude. It is accompanied with such an inward satisfaction that the duty is sufficiently rewarded by the performance. Fred De Witt Van Amburgh None is more impoverished than the one who has no gratitude. Gratitude is a currency that we can mint for ourselves, and spend without fear of bankruptcy. Edwin Arlington Robinson Two kinds of gratitude: The sudden kind we feel for what we take; the larger kind we feel for what we give. Lionel Hampton Gratitude is when memory is stored in the heart and not in the mind. Oscar Wilde The smallest act of kindness is worth more than the grandest intention. James Matthew Barrie Those who bring sunshine to the lives of others cannot keep it from themselves. Gordon T. Watts The depth and the willingness with which we serve is a direct reflection of our gratitude. John Wooden Things turn out best for people who make the best of the way things turn out. John F. Kennedy As we express our gratitude, we must never forget that the highest appreciation is not to utter words, but to live by them. Alice Walker Thank you is the best prayer that anyone could say. I say that one a lot. Thank you expresses extreme gratitude, humility, understanding. Courtland Milloy Nothing purchased can come close to the renewed sense of gratitude for having family and friends. Benjamin Franklin To the generous mind, the heaviest debt is that of gratitude, when it is not in our power to repay it. Ralph H. Blum There is a calmness to a life lived in gratitude, a quiet joy. Melody Beattie Gratitude unlocks the fullness of life. It turns what we have into enough, and more. It turns denial into acceptance, chaos to order, confusion to clarity. It can turn a meal into a feast, a house into a home, a stranger into a friend. Terri Guillemets As each day comes to us refreshed and anew, so does my gratitude renew itself daily. The breaking of the sun over the horizon is my grateful heart dawning upon a blessed world. G. B. Stern Silent gratitude isnt much use to anyone.

Free Essays on Merwin

The Language of Nature W.S. Merwin’s poems are of great lyrical intensity, concerned with darkness and light, the seasons, and the passing of time across landscapes. His lyrics capture the spiritual heartbreak of our time. He illustrates the bittersweet joys of vanishing wilderness in Native Trees, anger at our political wrong-doings in Term, and the emotions that memory can generate in Hearing the Names of the Valley’s. Merwin uses trees as a symbol of identity, specifically Hawaiian identity, in Native Trees. The first line states, â€Å"Neither my father or mother knew the names of the trees where I was born† (pg. 1). The child is curious to know about his culture and past, in which knowing these things forms identity. By asking questions about the trees, the child can have a greater sense of his identity. The parents do not answer his questions about the trees because they do not know the answers to them. â€Å"Both my father and mother said they never knew† (pg. 1). The reason to why they might not know the answers may be that the parents have never questioned the â€Å"trees† as their child does. It appears that they have accepted the deterioration of their Hawaiian identity while their child longs to find it. â€Å"There were no questions, They had forgotten†. The attention of their fingers were focused on the surfaces of furniture (pg. 1). Merwin portrays trees to be more than just a habitat of the land but as important as one’s identity. Merwin conveys, in the simplicity of language, a sense of political urgency using nature to represent the loss of the Hawaiian’s land. Merwin expressed the idea that nature was a part of everyone and the moment that you decided to harm a part of nature, you were, in actuality, destroying a part of yourself (video in class). In Term, the road, once walked upon by generations of men, represents Hawaii’s land. The people that have taken away this land cannot see that it is more than...

How to become a good leader Essay Example | Topics and Well Written Essays - 2250 words

How to become a good leader - Essay Example A lot of researches have been done to understand the definition and essence of leadership, to identify the differences between the managers and the leaders. Management of organizational behavior defines leaders as the "Men and women who saw the need for action, believed in what they were doing, inspired others and, in spite of incredible odds, changed the world." (Hersey, Blanchard & Johnson, 1). Many theories and meanings of leaders and leadership have been developed throughout the world. All these theories have not been providing with same results however they do agree on certain grounds. All the theories agree that a leader has a clear set of goals and is capable of setting examples. He is a person with strong beliefs and vision for the future. A leader bravely voices his opinions and takes actions on his beliefs and passions. Leadership is a quality or ability that a person possesses to influence and guide others. There are various theories that define and explain leadership. The major ones are the Trait theory, Behavioral theory, Contingency theory and the Transformational theory. The Traits theory identifies certain traits or behavior in a person. This theory believes that human are born with the traits of becoming a leader. The theory suggests that if a person posses the specified traits he is a leader. The Behavioral theory suggests that leaders have a specific behavior towards their followers and that makes them distinct from others. This theory specifies the style and the behavior of the leaders. The contingency theory acts as the critic of the above theories and specifies that the styles and the traits of the individuals can be different in different dynamic situations. This theory suggests that the leaders are defined by their activities and abilities. The characteristics or the behaviors cannot be defined or specified. The transformational theory stresses on the effective interaction of the leaders with their

In particular, the paper will focus on the process of policies development in South African higher education system while discussing the responses of higher education institutions regarding the alterations in the mode of curricula after policy developments in the country. Lastly, the researcher will put efforts to conclude the paper while proposing some recommendations that will be beneficial for the higher education system in the coming years. In addition, it is anticipation that such discussion and deliberation on higher education system of South Africa and its process of education policies formation will enlighten readers with differences in the policy formulation and its implementation in real scenarios. Furthermore, this paper will provide critical observations that will enable the experts in prioritise future educational policies Analysis of the literature (Johnson, 1996) has indicated that since beginning, public institutions have been dominating the higher education system in South Africa; however, since a decade, there has been an increment in the number of private institutions, an indication of successful policy alteration implementation. Moreover, there have been reports (Bitzer, 2009) of private-public partnerships as well in the same sector that points toward the growth of the higher education system. In particular, besides public institutions, according to the statistics of the year 2004, private educational institutions had approximately eighty-five thousand students in different academic programs all over the country (Bitzer, 2009). In addition, foreign educational institutions have also begun to operate in South African that is another indication of success in the policy

Managing Diversity Assignment Example | Topics and Well Written Essays - 2500 words

Managing Diversity - Assignment Example Successful organisations take pride in implementing diversity at work places and they devote some resources as well for taking care of this challenge. The changing demographics of UK further compound this challenge. There are a large number of ethnic minorities in UK, and a recent study projects that, by 2020 half of UK's population will be over-50, and a third of those between 50 and retirement age will be classified as disabled. Government of UK has also realized the need for paying more attention towards the diversity in the society and managing it. The 'Commission for Equality and Human Rights (CEHR)' has been set up by the Equality Act 2006, which emphasizes2 that 'Equality, diversity, and respect for the human rights and dignity of every man, woman and child are core values that define our lives in Britain.' The vision for the CEHR is based on the Government's view that equality is not a minority concern - it matters to every citizen. The commission will be fully functional by October 2007. While the spirit behind this act has got an overwhelming support from HR practitioners, apprehensions3 are also expressed by many speakers during a conference on race, held in London in November 2006. while HR professionals are taking a sigh of relief that the legislative mess of dealing with 35 Acts, 52 statutory instruments and 13 codes of practice on equality issues will be over with the implementation of CEHR, there are other speakers during this conference, who believe that racial concerns will slip down the agenda once they become just one part of the body's work, as it gears up to fight discrimination on seven fronts. A survey4 of 112 HR practitioners by Personnel Today's sister publication IRS Employment Review, shows that respondents hope the CEHR will make things simpler. It is worthwhile here to note that implementation of any law in letter and spirit depends on the intentions of the organisation and how seriously it values the corporate social responsibility. Therefore CEHR will have more of a guiding and nudging role in carrying out the tasks. In fact the survey findings also point out that 81% respondents would be happy if the commission just issued advice on good practice and tools for employers, rather than carry out investigations (40%) and legal enforcement (31%). Diversity Strategy and Organisational Effectiveness The global economy has made it almost mandatory for international corporations that an effective strategy is adopted for managing the diversity. Companies are moving towards flatter organizational structures, and the global economy is allowing the movement of the workforce across national boundaries, effective interaction amongst diverse workers becomes more critical for the smooth organizational functioning. In fact now that debate has started whether the concept of 'managing diversity; forms an alternative to 'equal opportunities' based on gender bias. In the UK, human resource practitioners and academics alike are becoming more aware of the emergence of managing diversity. There is now a view that, after twenty years of the '

Name: Sophie Griffith-Allen Section 1 – Know the employment rights and responsibilities of the employee and employer 1. Identify four main points that would be included in a contract of employment. If possible, use an example contract to support your answer (feel free to obscure any confidential information). In a contract of employment there are certain details which need to be included about the employer and employee, such as their names. Other information that must be included are about the job itself, such as job title, date of employment, duties and responsibilities that are expected from the employee. At Morrisons a probationary period of 13 weeks is included in a contract of employment and the employees contracted hours of work per week. 2a) List three key points of legislation that affect employers in a business  environment. Health and safety Act 1974 Copyright designs and patents Act 1988- Copyright refers to laws that control the use of the work of a creator, such as an artist or author. For a copyright to apply to a piece of work it must be an original idea of their own that is put to use. Data protection Act 1998 2b) List three key points of legislation that affect employees in a business environment. †¢ Pensions- Are very important for employees as the government think that people aren’t saving enough money towards pensions, as of 2012 pensions will undergo a considerable amount of change. †¢ Pay-there is lots of legislation about employee pay. Some examples include: The Equality Act 2010 which contains measures to protect women from being paid less than men for doing the same job. †¢ The National Minimum Wage Act 1998 an Act that was introduced to prevent very low pay. †¢ Employment rights and responsibilities- ‘Employees are expected to carry out their work in a way that has regard to the safety of others. Employers are expected to abide by a range of requirements governing such aspects as providing safe machinery and equipment, carrying out regular health and safety checks, ensuring the training of employees in health and safety issues, and carrying out a risk assessment to assess the dangers of particular work activities.’ http://businesscasestudies.co.uk/business-theory/people/rights-and-responsibilities-of-employers-and-employees.html#axzz2ENr4by5I 3. Identify a range of places where a person can find information on employment rights and responsibilities. You should identify at least two internal and two external sources of information. Sources of information where a person can find information on employment  rights and responsibilities are internal sources, such as books and documents held within the organisation, informed colleagues and line managers. Another source of information is external which are found outside of an organisation, such as libraries, the government, equality and human rights commission. 4. Describe how representative bodies can support employees. Representative bodies are one of the ways that employees can receive help and support in the work place. The best known examples of representative bodies are trade unions, which are a large organisation that represent the interests of their membership, they can offer assistance through work based representatives and they will also have regional and national expertise that they can use. Union representatives have a right to paid time to help employees, some of the areas where they can support employees are health and safety, workforce agreement, pensions, information and consultation representation. 5. Briefly describe employer and employee responsibilities for equality and diversity in a business environment. You should give at least two employer responsibilities and two employee responsibilities. If possible, provide relevant equality and diversity procedures from your workplace (or place of study) to support your answer. These documents should be annotated to highlight the relevant sections. In any organisation it is important for everyone to be treated equally. Employees and employers should be treated in a fair way and to be given equal opportunities. This is why there are certain responsibilities to be followed by employees and employers to prevent discrimination, such as people who are doing the same job equally well should all be rewarded fairly. It is morally right to treat people fairly and to avoid unfair discrimination. To prevent discriminatory and unfair behaviour there have  been many laws put in place. Both employers and employees should make sure that inappropriate labelling, stereotyping and prejudice do not influence the way an organisation operates. ‘At Morrisons the issue of equality and diversity are taken very seriously. They recruit, develop and keep the most talented people regardless of gender, race, disability, age sexual orientation, religion and nationality. Morrisons is dedicated to being an equal opportunities employer and support all employees to make the best of their skills’. ‘’Our policy aims to ensure that no job applicant or employee receives less favourable treatment. We will treat staff, potential staff and the public fairly and with dignity’’. 6. Briefly explain the benefits of making sure equality and diversity procedures are followed in a business environment. Your answer should include one benefit for the employer, one benefit for the employee and one benefit for the overall organisation. Benefits of making sure equality and diversity procedures are followed in a business environment are: Employer: Reduces the incidence of bullying and harassment. Employee: Employees will want to work harder, they feel valued, happier and more efficient. It will increase the chance of open competition for opportunities. Overall organisation: As employees are treated with equality organisations will be more successful. Helps to maintain morale and motivation of the workforce leading to increased quality of products, overall it will become more of a successful organisation. Section 2 – Understand the purpose of health, safety and security procedures  in a business environment 1. Identify employer and employee responsibilities for health, safety and security. If possible, provide relevant health, safety and security policies / documents from your workplace (or place of study) to support your answer. These documents should be annotated to highlight the relevant sections. Employers and employees in any organisation have a legal duty that the working environments are safe and secure. The health and safety Act should be followed at all times. Employer responsibilities: Are to provide a secure, healthy and safe workplace that is free from hazards recognised by the organisation. Ensure that employees have safe tools, equipment and materials. Ensure that equipment provided is always properly maintained. Employers must report any fatal accidents. Employers must provide employees with accurate training and medical examinations when required. Employees responsibilities: Are to inform employers of any hazards that have accrued in the workplace. Report job-related accidents that result to injuries and illnesses. Follow the regulations of health and safety that are set by the employer. Familiarise and obey with the organisations standards. ‘Morrisons are committed to achieving and maintaining the highest standards of health, safety and security standards across the company. All staff at Morrisons receives regular health and safety training. There are many rules that all staff at Morrisons must follow in order to prevent any harm not only to staff but to their customers as well, such as always checking floor surfaces are clean with no spillages etc. Morrisons makes sure that there are always staff present that are first aid qualified in case of any incidents or accidents that have taken place. If any accidents or incidents  did occur within Morrisons all staff recognise that they must be reported as soon as possible.’ 2. Explain the purpose of following health, safety and security procedures in a business environment. The purpose of following health, safety and security procedures in a business environment include: Ensuring the safety and welfare of the individual and others is kept at all times. Ensuring the business/organisation is following relevant legislation. 3. Describe three different ways of maintaining a safe and secure business environment. Ensuring all employees have the necessary safety equipment. Taking time to find where health, safety and security responsibilities lie. To promote a safe working environment is to make sure that safety equipment used by employees is often maintained. Workers must always wear suitable clothing given for the job.

Green Energy Means Renewable Energy Environmental Sciences Essay

Green Energy Means Renewable Energy Environmental Sciences Essay Green energy means renewable energy that is vast alternative for the use of fossil fuels such as petroleum. Other conventional method used to provide electricity is such as geothermal, biomass, ocean, solar, wind, hydro, hydrogen fuel cells and etc. Biomass energy is derived from the wastes and animal dung either by burning it or just leaving the wastes to lay off by itself to get biofuel or biogas. Ocean energy is gained from the sea and there are two types of them such as thermal energy and mechanical energy. Hydrogen must go through reformation process or electrolysis process to be able to use for the fuel cells to provide electricity. The objective of the project is to choose seven types of renewable energies and explain its applications and advantages in detail. 1. Introduction Green energy is sustainable energy, which means meeting the needs of the present without compromising the future[2]. These alternative energy sources are said to be not harmful to humans and environment and also arenon polluting energy sources. It basically reduces pollution and the impact on the environment that the existing energy source is causing now and in the past by conventional energy sources such as fossil fuel, coal and wood. These are non renewable energy sources, also known as the brown energy[1]. These sources are mainly used in the production of electricity, heating and fuel for boilers. They cause excessive amount of pollutants, such as carbon monoxide and nitrogen oxides, together with particles that could harm humans. These pollutants are the main contributors to the greenhouse gases that cause global warning. Brown energy are also types of sources that are typically reducing on our earth, which means it could not be re-produced to be used in future. The main aim for this study on green energy is to literate the reader on what is green energy and the importance of these energy to substitute our current conventional energy resources. These report is also to identify the main types of green energies available for the current technology practised in our world today with the history of energy development that brought to the practice of green energy. 2. Green Energy Sources of green energy come from the nature itself, being free to be harvested. They are mainly derived from the sun (solar power), wind and water. Wind turbines have been used since old times to grind grains, where the term windmill is derived from. A more expensive source would come from nuclear and bioenergy (biofuel and biogas). Nuclear power is also categorized in green energy as it does not produce greenhouse gases. Waste from nuclear power plants are problematic and dangerous to be handled as it takes hundreds to thousands of years to decay before reaching the level that is not harmful to humans, plants and the animals. But in order to completely wipe out the usage of fossil fuels to produce electricity, the number of nuclear plants has to be increased so that greenhouse gases emissions can be cut down massively.[3] Energy from sun, wind and water are continuous but inconsistent. Rainy days that could affect solar power production and droughts that would affect water levels in dams are the main drawbacks of these energy sources. As renewable energy is sometimes inconsistent, excellent storage capacity is needed to store energy that are produced. It is usually windier in the night time, but the demand would be lesser. Nuclear plants generate so much power at a particular time that they cannot be used at once. So large battery banks are required in order to mesh with the electricity system and provide a consistent power supply. 2.1 History of Energy Development The history of energy consumption of human being dates back to 3000 BC where the Mesopotamians used petroleum to caulk ships and to build roads. Coals were used during the Bronze Age to heat up iron and shape them, as well as in the Roman culture. This long history of non-renewable energy usage has urged the emergence of green energy to replace them in order to keep the future generation safe.[4] 2000 B.C. Crude oil was used to light lamps and heat up homes by the Chinese. 200 B.C. Salt produced from brine using natural gas from underground by Chinese. 600 B.C. Static Electricity found by Thales of Miletus by rubbing amber. 250 400 A.D. First water-powered Mills built by the Romans 600 A.D. Greek Fire was invented by the Persians and Arabs, a form of burning liquid used greatly in the Byzantine Empire as weapon. 500 900 A.D Windmills were built to pump water and grind grains by the Persians. Late 1500s Coal was imported greatly by US, up to 108,000 tons until the 1800s. 1700s A kite that transmitted electricity through its wet cord was found by Ben Franklin. A breakthrough in electricity discovery. 1800-1826 US had the first electric utility. Mid 1800s-1950 Wood as the primary source of fuel, but decreased after the shift back to coal. 1870-1880 Gas and alcohol using first combustion engine. First U.S. power plant to produce electricity opened (Thomas Edisons Pearl Street Station) 1888 First wind turbine generating electricity in Cleveland, Ohio. Early 1900s Geothermal used to produce electricity commercially by the Italians 1938 Nuclear Fission discovered by the Germans. 1940-1950 The Atomic Energy Act implementation and the first electricity were produced by using nuclear power. 1950s First silicon solar cell was invented (solar photovoltaic). 1960s National Environmental Policy Act and Clean Air Act in US implementation to protect the environment and reduce pollution. 1970s Department of Energy (DOE) were formed. Water from power plant was controlled with Clean Water Act in 1972. 1974 Development of renewable energy was initiated and supported by the National Renewable Energy Laboratory. 1980s First wind farm built in the United States.2.2 Giga watts of power produced in California. 1990s Natural gas was used in almost 50percent of homes in US for heating. Towards the Greener Solution Till 2007, 24 states adopted policies for increasing the production of renewable energy. 2.2 Importance of Green Energy Research from scientific evidence are showing that what this present generation is doing will impact the environment in the next 50 100 years. The fact that only one earth is known by human being urges government and private sectors to find solutions to reduce pollution and having a lifestyle that is more eco-friendly. A few reasons on why green energy is important. Non renewable fossil fuels burning are causing greenhouse gases that cause global warming. Carbon dioxide, methane and nitrogen oxides are released into the atmosphere, dissolving into raindrops and causing acid rains. Acid rains damages crops, plants and forests. Aquatic organisms are also affected by this as lakes and rivers pH levels are altered. Human built structures such as steel bridges, marble statues and limestone buildings are being eroded by acid rain.[10] Figure 3 is a pie chart showing the anthropogenic greenhouse gas emissions in the U.S. by gas type. Fossil fuels such as oil and coal are also supply that is not endless. Sooner or later the supply will vanish and unavailable for future generations. Wind, water and solar energy are constant, sustainable and 100 percent clean energy. It does not cause negative impact on environment such as pollutant and waste. This energy type is free as well. Humans would benefits in health as reduced pollutants would provide cleaner and more breathable air. Lands would be saved as waste management is not necessary. Cleaner water for domestic usage and aquatic organism a would be available. Jobs opportunity would arise in rural areas as most renewable energy plants are located far from cities. Regional development also would benefit from this.[8][9] 3. Types of Green Energy 3.1 Biomass Biomass is derived from farm wastes, animal wastes, plant oils, crops and some kind of garbage [11]. Energy that is generated from the wastes is called bio power or bioenergy [11]. Biomass can be processed further to obtain biofuels or burned directly to obtain bioenergy[11]. The energy obtained from burning the wastes can be converted into heat, electricity and mechanical energy [1]. 3.1.1 Types of biofuels Solid form its obtained from the burning of organic material such as animal wastes, wood, grain and other types of garbages [11]. Liquid form- its obtained straight from the plant and does not involves any burning of material [1]. Biodiesel can be taken as an example for this type of form. It is extracted from vegetable oils or animal fats [11]. Gas form its obtained from organic waste such as dead plant and animal wastes when the organic material breakdown naturally without the need of oxygen [12]. Biogases consist of methane that is essential in terms of natural gas [12]. 3.1.2 Application of biomass Widely used in transportation in the form of gases Electricity generation plants Gas produced from the biomass gasifier must be cleaned first before cooling it down and use it as a fuel to run an IC engine that is coupled together with the generator [13]. Heat application Biomass is used as a fuel to provide energy for the fuel-fired furnace that is often used for high end outputs such as[13 ]: Forging furnace Ovens Kilns Dryers Small boilers Direct fire process heater Re-rolling mills 3.1.3 Benefits of biomass energy Biogases that are used as fuels gives more mileage for cheaper price compared to fossil fuels Energy from biomass has got no ending to it since human throw wastes in daily basis and animals also constantly produce muck Energy gained from burning the wastes releases carbon dioxide to the atmosphere and the carbon dioxide that is released from the burning is useful for the plants in terms of photosynthesis process. Each country has their wastes in terms of plants, animals dung and garbages, these materials is available locally. This can reduce the need for foreign investors in the country thus improve the nation economically as well Biomass in mass production can reduce the increase in global temperature significantly. 3.2 Ocean energy Ocean energy is gained from the sea. There are two types of energy gained from the ocean such as thermal energy and mechanical energy [15]. Thermal energy is gained by the difference in temperature between the warmer surface of the ocean and the deep cold ocean water [15]. Mechanical energy is gained from tidal and wave that is used to rotate the turbine to provide electricity in most of the power plants available [15]. 3.2.1 Types of energy gained 3.2.2 Thermal energy The difference between the temperatures should be around 38 Degree Fahrenheit in order to build a power plant that can fully utilize this temperature difference to make energy [16]. There are 3 types of cycles involved in electricity conversion system from the heat energy such as: Closed cycle The heat at the surface of the ocean water is used to vaporize an ammonia type of fluid which has low boiling point and the vapor expands to turn the turbine to produce electricity [15]. Open cycle The sea water in this case is kept at low pressure in order to force it to boil at low temperature and the steam produced from the sea water is then used to rotate the turbine to activate the generator to produce electricity[15]. Hybrid The combination of both open and closed cycles is used to rotate the turbine in a most economical way [15] 3.2.3 Mechanical energy Tidal energy its gained as the earth rotates and the gravitational pull of the moon. The principle of tidal energy is when the tides is at high point the water is trapped in the dam and as the tides began to reach the low point, the trapped water is released to rotate the turbine at high speed to generate electricity[15]. The concept is similar to hydroelectric power plants [6]. Wave energy Existing kinetic energy from the movement of the waves is used to power up the turbine [15]. The concept is simple that the waves from the ocean comes into the chamber from the right, as the rise of the waves will force the air to release from the chamber and the released air is the one that will rotate the turbine to provide electricity as shown in the figure 1 below[16]. The higher the waves, higher are the rotation of the turbine. http://www.energyquest.ca.gov/story_old/images/chap14_wave_2007.gif Application of wave energy [16] 3.3 Hydrogen and fuel cells energy Hydrogen best identified as the simplest component [18]. One proton and one electron are the sub elements inside an atom of hydrogen [18]. It has a limitation is that it doesnt appear by its own in the earth. Hydrogen atom always combined together with other elements such as water [17][18]. The molecular weight of hydrogen is 1kmol and the lightest weigh among all the other natural components available in earth. Hydrogen can be separated from hydrocarbon by heating process and this is called reformation process [18]. Electric current also used to separate hydrogen from water and the separation process is called electrolysis [18]. Fuel cells function is to convert hydrogen to electricity directly without any other processes in between [18]. Reformation of methanol, gasoline and natural gas can provide hydrogen for the usage of fuel cells [18]. Methanol can be used directly for some fuel cells without any reformation process [18]. 3.3.1 Applications of hydrogen and fuel cells NASA used liquid nitrogen as a fuel for the space shuttles and other rockets. Liquid nitrogen does not emit any harmful material after the combustion [18]. The product of the conversion by hydrogen fuel cells is pure water that is used as drinking water by the astronauts [18]. Hydrogen powered vehicles is among the growing applications of energy since hydrogen fuel cells capable of providing power for buses[21]. Fuel cells also can provide electricity for a residential housing area that is big as a traditional AC unit [21]. It can operate 24 hours a day and 7 days a week. 3.3.2 Advantages of fuel cells Efficient conversion of energy from hydrogen to electricity without any combustion taking place and the byproduct is water[19][20] The noise level created from an operation of a fuel cell relatively much more quiet than the conventional motors[20] Easier maintenance since less moving parts[20] Life span is longer than a battery since it has no memory effect when its refueled[10] The source for fuel cells are hydrogen and it is available with water[20] Can reduce the nations usage of fossil fuels since fossil fuels come at higher price than hydrogen that is naturally available in the earth [20]. 3.4 Geothermal Energy Geothermal energy is a form of thermal energy stored by generation of heat from radioactive decay of minerals occurring inside the earth (80 percent) and from the original formation of the planet (20 percent).[6] Due to the temperature differences between the earth core and surface, continuous heat transfer occurs from the core to surface. Radioactive decaying of natural materials such as uranium and potassium that occurs at the core creates a temperature reaching over 5000 degree Celsius and very high pressure.[7] This high temperature and pressure causes melting of surrounding cooler rocks and these results in the formation of magma. This magma then heats up the rocks and water in the crust which can go up tp 370 degree Celsius.[6] In the range of 10kilometers of earth surface contains heat energy that is 50000 times more than all the oil and natural gas sources in the world.[7] The typical place that usually spots geothermal activities is regions with active volcanic activities. T his usually occurs at places where the earth crust is thin enough to let the heat out. Earthquake and magma movements breaks up the rocks covering and allows water to circulate, producing natural hot springs and geysers as the heated up water reaches the surface. As these hot and pressured water forms a reservoir type of containment underground, wells are usually constructed to harvest electricity or heat. 3.4.1 Applications Steam produced from the reservoir containing pressured and hot water are usually used to power turbines in power plants that generates electricity (Steam Turbine), while other power plants uses the hot water in the reservoir to boil a working fluid that vaporizes and moves a turbine. Heat produced by hot water near to the earth surface can be directly used for heating purpose. The applications that utilizes these direct heat includes heating buildings and homes purpose, growing plants in greenhouses, drying crops, heating water at fish farms, and also in pasteurizing milk processes at milk industries. This is done by using geothermal heat pumps. There is also formation of hot dry rocks, usually 4-10kilometers from earth surface. Technologies is existing to inject cold water onto these hot dry rocks, circulating them through the cracks of the rocks and drawing back the heat from another well located at the end of the water circuit.[5] http://www.bbc.co.uk/schools/gcsebitesize/science/images/131_geothermal_energy.gif Water pumped down through injection well and collected at production well. http://www.ucsusa.org/assets/images/ce/geopower3.gif How geothermal heat used to power turbines. 3.5 Hydropower Hydro means water, so hydropower basically is the power that derived from the force of moving water and generates electricity at damn by water falling throughout the turbines. [22] The fall of water and movement is part of a constant ordinary cycle known as water cycle. Water in the earths ocean and rivers evaporates by energy from the sun and draws it ascendant as water vapour. Once the water vapour reached the cooler air in atmosphere, it automatically abbreviates and forms as clouds. [23] Hence, the moisture fall to earth as rain and fill the water in oceans and rivers. The moving of water from higher ground to the lower ground with the gravitational force and it drives the water extremely powerful to assist generates electricity for daily usage of human being.[23] Hydropower is a one of the worlds biggest source of renewable energy and play important role or facing challenges during period of climate vary. [24] Hydropower also is considering clean energy source because it does no t release any toxins to damage the environment. [25] Figure 3.1: Water cycle diagram 3.5.1 Types of Hydropower Hydropower is primarily used to generate electricity. There are few types of hydropower which is common usage in world. Micro hydro: provide few hundred kilowatts to remote villages, homes and small industries.[26] Pumped-storage hydroelectricity: stores the water that has been pumped during low demand and generates it when demand is high.[26] Run-of-the-river hydroelectricity: it will capture the kinetic energy in rivers without using dams.[26] Conventional hydroelectricity: power comes from the potential energy of dammed and water drives the turbine to generate electricity.[27] The most common type of hydropower that has been used is conventional hydroelectricity known as hydroelectricity power plant which is uses a dam on a river to store water in a reservoir. This power station is usually placed in hill areas so can build dams easily and can obtain larger water reservoir and generate huge quantity of electricity. [28] 3.5.2 How is hydroelectricity power produced?http://cwc.gov.in/Kids%20Corner_files/hydropower.gif Figure 3.2: Simple Hydropower station diagram In hydropower station, the potential energy that stored in body of water at a given height is converted to kinetic energy which is used to rotate the turbine and produce electricity. [28] In the generation of electricity by using hydroelectric power, water is accumulated or stock up at higher level and guide descending through large pipes to lower level known as penstock. [29] Once the water reaches the end of the penstock with higher pressure it will hits and drives the turbine to create mechanical energy from kinetic energy. Turbines rotate the connected to shaft which is turn the generator and change mechanical energy to electrical energy. [9] Inside the generator there is rotor that covers by turbine. Large electromagnets are attached to the rotor located within coils of copper wires called as stator. Flow of electrons is formed in the coils of stator when a generator rotor spins the magnets. [31] This produces electricity that can be step up in voltage through the station transformers and centre cross transmission lines. Therefore, transmission line conducts electricity from hydropower plant to the distribution system. There are certain advantages and disadvantag es of using hydroelectric power station: Advantages It is constantly renewable remaining to the habitual nature of the hydrologic cycle. The water that been used for generation of electricity can be utilize for irrigation, boating and fishing, kayaking and etc. Fuel is not burned so there is minimal pollution and no waste is produced Using water to run the power plant that provided free by nature Disadvantages Only at limited places hydropower plant can be constructed. Dams are expensive to build. Possibility of dam collapsing 3.6 Solar energy Solar energy is the radiant energy emitted by the Sun that is converted into thermal or electricity energy for homes and industry usage. The amount of energy falling on the earth is given by the solar constant, but very little use has been made of solar energy. [32] Renewable and sustainable energy source such as solar energy make use of it around the world to produce electricity for number of different purpose and its use is both environmentally-friendly and cost-effective over the long term. There are varieties of technologies that have been used to take benefits of solar energy. Types of technologies such as photovoltaic system is common have been used to develop solar energy for daily and powering numerous applications. [33] Photovoltaic system (PV) is solar cells or panels directly convert sunlight into electricity. [34] The conversion of sunlight directly into electricity (DC) will be done by solar cells. Electricity from solar cells is stored in the battery for instant or future usage and where an inverter is required to change the Direct Current (DC) to Alternating Current (AC) to power the most AC appliances. [35] Photovoltaic system solar cell made of semiconducting materials that related to those used in computer chips. Once the rays are engaged by these materials, the solar energy knocks electrons loose from the atoms, via allowing the electrons to flow through the material to produce electricity. This process of converting light (photon) to electricity (voltages) is called as photovoltaic (PV) effect. [36] The simple of photovoltaic (PV) system illustrated in figure below that can explain about it.A diagram of how the components of a PV system interact with each other. Figure: Simple Photovoltaic (PV) system with components The electricity that generated can be stored or directly utilize by photovoltaic standalone system, or a huge electricity grid powered supplied by central generation plants (photovoltaic grid-tied system), or else joint with single or numerous domestic electricity generations to supply into small grid (photovoltaic hybrid system). [37] Supplying of DC and/or AC electrical load that operate independently of the electric utility grid is designed by standalone photovoltaic system. Direct-coupled system is of the simplest type of standalone photovoltaic system that the DC output of a module or array is directly connected to a DC load (figure). [38] When there is no electrical energy stored in batteries in direct-coupled system, the load can operates during the sunlight. So, common applications that used for example water pumps, ventilation fans and small circulation pumps for solar thermal water heating systems are appropriate. [38]A diagram of a stand-alone photovoltaic system. Figure: Direct coupled PV system Hybrid system only integrates more than one generating source, which may use an engine-generator, wind, or utility power as a supplementary power source. Initially the battery store is recharged by the photovoltaic system once insufficient the generator charges the batteries. Solar Hybrid System Figure: Photovoltaic hybrid system Grid tie photovoltaic system is deliberate to work with utility grid power. Direct Current (DC) power from the Photovoltaic array into Alternating Current (AC) power is converted by the inverter. AC appliances or local utility company can make use of the direct AC power.Solar Grid-Tie System Figure: Photovoltaic Grid Tie system 3.7 Wind Energy Wind energy is the renewable power or energy which comes from the air that flowing across the earths surface. Wind energy is a converted form of solar energy. [40] Wind is exist due to uneven heats of the atmosphere by sun, the irregularity of the earths landscape and rotation of the earth.[41] Movement of air from region of higher pressure level to region of lower pressure level is also known as wind. When hot air increases, the atmospheric pressure will reduce at earths exterior, and the cooler air will travel in to fill up the void. In fact, flow of wind patterns are personalized by earth landscape, vegetative cover and bodies of water. One of the fastest growing sources of electricity and fastest growing markets in the world today is wind energy because is green power, sustainable, affordable, and economic development. [42] In wind turbines there are consist of horizontal and vertical axis wind turbines been designed for rotation function. 3.7.1 How a wind energy or wind turbine is work? Terms of wind energy or else wind power illustrate the generation of mechanical power or electricity by using wind. Air has mass when it is in motion, and it contains the energy of that motion, known as kinetic energy. [40] Therefore wind turbines are usually use to harvest the kinetic energy and convert it by using inverter into utilizable which can provide electricity for home, business applications and for sale to utilities. Wind turbine also produce mechanical energy that harvested from kinetic energy to drive machinery, for instance grinding grain and pumping water, the device called as windmill or wind pump in rural place. wind energy diagram Most common method to generate electricity is by using wind turbines. Figure 1 is explaining the simple understand on working principle of wind turbines. Explanation from the figure 1, wind will turn the large turbine blades; the turning energy will spins a generator shaft and produces electricity. The electricity that produced by wind turbine is Direct Current (DC) and it cannot use because household appliances and use Alternating Current (AC). Hence, inverters connect to wind turbines to the mains power of a building and used to convert the DC electricity into useable AC electricity. [43] Small-scale of wind energy does not use inverters, as an alternative using the wind energy electricity can be charge batteries, connected to buildings main power or else connected to national power grid. [44] Advantages There are no fossil or fuels required to generate electricity [45] Wind energy does not pollute at all so does not harm environment or discharge any toxic gases[7] Wind energy directly can be used as mechanical energy[47] Disadvantages Once there is no wind, solar energy or geothermal energy use as alternative way to generate electricity [48] Need expensive storage throughout peak production time.[49] Requires large scale area to build wind farm.[49] 4. Conclusion Green energy is the only visible solution so that the future generations are not compromised
