Essay --

Intense on lawbreakers, delicate on wrongdoing: force, drugs and the disappointment Over the ongoing past one of the serious issues has been that of contentions between the crooks and the general public all in all. There has been banter in regards to the realities whether we have dealt with the issues all the more apropos or not. Since there are sure ways of thinking that are of the supposition that we ought not go delicate on the wrongdoing side regardless or structure. It is this universe of the sorted out wrongdoing that is answerable for all the force misuse and the medications and they have caused, actuated and now and again paid off the individuals to carry the social framework to a stop. It is all their doing which can end up being unreasonably exorbitant for the individuals and the way of life just as for the economy all in all over the long haul. According to the contention point of view, the differential structure of social force essentially necessitates that prevailing gat herings to practice power over subordinate gatherings however is that actually the case? Truly we do require some type of predominance and the other over the timeframe however is that actually all that there is to life? In all actuality on the off chance that we take a gander at things this is the manner in which we have started to see things on the grounds that a greater and a superior society needs individuals to be increasingly open and they should be progressively able. They are the ones who need to take a gander at the things and it is dependent upon them to decipher the implications of the things in the strict sense. On the off chance that we begin to accept that the individuals will rule others and there are some who are accommodating and harmless and there would others say others are who are acceptable at administration and who are acceptable at controlling things is that the adequate motivation to permit them to do the things their way? As I would like to think it ought to never be that way essentially in light of the fact that the individuals who have the force ... ... move constantly. It is about the idea of dependence and the subordinate wrongdoing related with it, which causes such a significant number of individuals to get trapped in everything. Despite the fact that there has been a great deal of discussion about the treatment and recovery and the explanation behind that will be that it is altogether more affordable and progressively viable. Open wellbeing is something that is totally reliant on how well we can control the previously mentioned social wrongs on the grounds that before them it turns into an auxiliary thing. Imprisonment isn't generally the main arrangement that is accessible to the specialists since that may discourage the universe of sorted out wrongdoing however it doesn't strike at the very roots that it is established on. That is the entire target that we ought to abstain from going delicate on the universe of wrongdoing no matter what in the event that we need to get any opportunity of saving the holiness of things to c ome ages.

You cant really see anything in that picture. But what my friend had noticed was that several of the buildings had tiny stickers on them, picturing hacks that had happened on those buildings in the last few years. I was really entertained by this clever and subtle hack, so I took pictures. Ill also summarize the pictured hacks for you. Its been a while since the Hack Gallery was updated, and only a couple of these hacks have been put in it. Most of the hacks, youll notice, are cross-group, and the team working on the hack often included members of such groups as Jack Florey, James Tetazoo, the Order of Random Knights, the Western Hacking Organization, and/or no group at all.

Courts Have Developed And Limited Law For Psychiatric Victims - Free Essay Example

Sample details Pages: 8 Words: 2270 Downloads: 4 Date added: 2017/06/26 Category Law Essay Type Critical essay Level High school Did you like this example? Critically analyse the way the courts have developed and limited the law in relation to claims for psychiatric harm by secondary victims Date authored: 24 th May, 2014. As Lord Steyn noted in his judgment in White and Others v. Chief Constable of South Yorkshire and Others, 1 the law on the recovery of compensation for psychiatric harm is: a patchwork quilt of distinctions which are difficult to justify What Lord Steyn meant by this is that; the law regarding claims for psychiatric harm has been developed in a piecemeal way through common law and can often be seen to conflict with itself in many areas.2 It is due to this that claims by secondary victims for psychiatric harm are often hard to assess as to their likely success and merit in a court of law. 3 There is also an argument that recent policy decisions by judges have overly restricted a secondary victims access to justice. First of all it is important to understand what is meant by the terms primary and secondary victims in relation to psychiatric harm and what the difference between these potential claimants is. Primary victims were first identified in Dulieu v White 4. Th is case established that a primary victim can recover damages for psychiatric injury stemming from actual physical injury or from a reasonable fear or apprehension of danger to their physical safety. This was expanded in Page v Smith5 Don’t waste time! Our writers will create an original "Courts Have Developed And Limited Law For Psychiatric Victims" essay for you Create order where it was held that if physical harm is foreseeable, the claimant can recover in respect of both physical and psychiatric harm, even where the latter is not in itself foreseeable. This reasoning was applied in Corr v IBC Vehicles Ltd6 where the House of Lords held that Corr was a primary victim and his psychiatric illness was the same ‘type of harm as his foreseeable physical injuries. His suicide was not an uncommon manifestation of depression. It could be argued that Lord Lloyds definition of a primary victim as a party who is within the zone of physical danger7 limits the primary victim category. However, Lord Hope in Grieves v FT Everard Sons8 cautioned against expanding this category for policy reasons and to prevent opening the potential floodgate for psychiatric harm claims. These same cautious policy considerations can also be seen when examining the secondary victim category and the criteria needed to make a claim as a secondary victim for psychiatric harm. There is also confusion among judges and claimants about which category a claimant may fall in to. 9 A secondary victim can be described as someone who is not personally at risk of physical injury but who suffers psychiatric injury as a result of witnessing someone else being harmed or endangered. One of the main policy considerations for this category of claimants is that the psychiatric injury suffered must be reasonably foreseeable in a person of ‘ordinary fortitude in the same circumstances. In Bourhill v Young10 the House of Lords rejected a claim on the grounds that the claimant was not herself in physical danger and that she was particularly susceptible to shock. It could be argued that this area of law should follow the thin skull rule established in Smith v Leech Brain Co11 and that just because a person is particularly susceptible to harm, this should not remove the defendants liability.12 Indeed, the modern approach set out in McLoughlin v OBrian 13 does not place so much emphasis on a persons fortitude but more on the principles of reasonable foreseeability or by independent policy-based factors. These factors include the closeness of the relationship between the claimant and accident v ictim, the proximity of the claimant to the accident itself and whether the shock was induced by what the claimant saw or experienced as opposed to what they were told after the event. It could be argued that this is a much fairer system as it allows for a more level playing field for claimants and that the (possibly outdated) notion of a persons fortitude is partially dispensed with. However, after this case the mood shifted towards a more restrictive approach in Alcock v Chief Constable of South Yorkshire Police. 14 This was a test case involving ten representatives of the friends and families of the victims of the Hillsborough disaster and it is from this case that many of the issues surrounding secondary victims arises. None of the claimants were able to recover as primary victims as they had not been directly involved in the disaster but the court had to consider whether they could recover as secondary victims. The Chief Constable of South Yorkshire Police admitted negligence in respect of those who had been killed or injured at Hillsborough but argued he did not owe a duty of care to those who had suffered psychiatric damage as a result of seeing or hearing the news of what had happened. The claims were rejected by the Court of Appeal and the House of Lords and Lord Oliver set out guidelines (known as Alcock control mechanisms) as to when a claim should be allowed. These related to the class of persons whose claim should be recognised, the proximity of the claimant to the accident a nd the means by which the shock is cause. This has severely limited the scope for who may be classed as a secondary victim and has arguably led to confusion and therefore a lack of parity in judgements.15 Firstly it must be shown that there is a ‘close tie of love and affection between the claimant and the accident victim. This is presumed in spouses; and parents and children (this can be rebutted) but not presumed in siblings and other relatives (they must prove this tie exists). It could be considered that this is unfair and overly limiting. Asking a sibling to prove they had a close relationship to a victim could be argued to be emotionally damaging, especially considering the claimant may already be suffering from a psychiatric illness due to the death of a loved one. Conversely, presuming this relationship between parents and children may not be the correct approach. A claimant who did not have a particularly close tie to a parent may attempt to make a spurious claim based on this policy. Secondly a claimant must prove their proximity to an accident or happen upon its immediate aftermath to have a successful claim. However, cases have shown that this policy rule may be overly subjective and is not applied evenly or fairly across all cases. For example in Mcloughlin 16 it was agreed that witnessing the victims injuries two hours after the event was enough to establish proximity. However, in Alcock17 it was deemed that witnessing the aftermath nine hours after the event was not sufficient to establish proximity and therefore establish a claim. The later case of Galli-Atkinson v Seghal18 allowed a mothers claim for psychiatric harm saying the aftermath could be viewed as being made up of different parts – the visit to the scene and the hospital morgue. These three differing judgements show that Lord Steyns patchwork comment to be accurate when dealing with secondary victims. Thirdly there is the requirement that there must be immediate perception and shock. That is to say that the harm must be sustained as a result of the sudden and direct appreciation of a shocking or horrifying event rather than as the result of a continuous process of dealing with or responding to such events. Potentially conflicting judgments can also be seen here which may overly limit the scope for potential claimants. In Sion v Hampstead Health Authority19 it was ruled that a father did not satisfy the immediate perception requirement as he watched his son die over a fourteen day period. However in Walters v North Glamorgan NHS Trust20 a mother was allowed to recover for damages after the death of her baby son. The Court held that the aftermath wasnt confined to one moment in time and the thirty six hour period could be classed as a single horrifying event. Limiting claims in this way could be considered very unfair. Not everyone is affected by events in the same way and is it fair to say that because someone took a long time to die means that a claimant has suffered less psychiatric harm because of this? 21 It could be argued that in fact, they may have suffered more psychiatric harm due to the prolonged nature of the events. Other potential secondary victims have also seen their scope for claiming limited in recent cases; for example, psychiatric harm suffered by emergency service workers and rescuers. In the past the judi ciary have tended to allow claims for rescuers.22 However in White 23 the House of Lords held that neither a rescuer nor an employee was placed in any special position in relation to recovery for psychiatric harm by virtue of being a rescuer or employee. This therefore limited claims for recovery for psychiatric harm. It could be argued that emergency services personnel should be limited in their scope for claiming psychiatric damage as they would have known and accepted the risk by entering in to this line of work. However, establishing a blanket approach may limit their access to justice for extremely horrific events resulting in psychiatric harm. Claims for witnessing self harm have also been limited. Where a claimant suffers psychiatric harm after witnessing the defendant negligently injure himself public policy grounds have been used to deny recovery for damages. 24 There have been calls for legislative intervention. The Law Commission Report on Liability for Recovery f or Psychiatric Illnesses 1998 25 concentrated on the position of secondary victims recognising the flood gates arguments. It suggested the ‘control mechanisms in Alcock should be modified by restricting the criteria of proximity and concentrating on the requirement of a close tie of love and affection. The Law Commission recommended a fixed list of relationships where a close tie would be conclusively proved. It also recommended the abolition of the requirement of a sudden shock and that it should include negligently inflicted psychiatric injury that had developed over a number of years. The Commission also wanted liability for situations where the defendants actions in imperilling themselves caused the claimants psychiatric illness. They incorporated a draft bill (Draft Negligence (Psychiatric Illness) Bill) and attached it to the Report but Parliament has yet pass this in to legislation. In conclusion then, while it is fair to say that not everyone should be able to claim for witnessing an accident, as it would lead to an overwhelming number of cases, there is an argument that the courts may have overly limited the scope under which a secondary victim can claim. The proximity considerations, closeness of relationship and immediate perception requirements have been shown to be potentially over limiting and unfair. Judgements could also be said to be inconsistent and this makes it difficult for the public to have confidence in the court system. It is likely that legislation is needed to codify existing case law to allow for a fairer system with greater parity and consistency. However, the fact that sixteen years have passed since the initial draft stage of legislation aimed at solving the problems, shows that this is not a priority for recent governments.

Global Warming And Its Effects On The World - 1074 Words

It would be a rare week indeed without hearing about global warming on the television or radio, or reading about it in the newspaper or an online blog. There have been many opinions from an abundance of points of view on the subject. Scientists, politicians, and environmentalists have all weighed in on the debate, and each of them is passionate about their beliefs. Some issues brought about due to global warming are polar ice caps melting, glaciers receding more and more each year, and rising ocean levels. These problems can lead to dwindling food supplies, fewer drinking water sources, and coastal flooding, to name a few (Miller 58). Essentially, the primary issue with global warming is whether humans are causing the planet’s climate to warm to damaging levels. Contrary to what the mainstream and social media would lead people to believe, global warming is most likely a natural cycle that planet Earth witnesses. Considering that politicizing global warming has become a national distraction, much of the discussion has become vague as to what is even at the core of the debate. To comprehend the debate about global warming, one needs to understand the definition of global warming. Global warming is the average temperature increase of the Earth’s oceans and atmosphere over the last century.

Subjects to Citizens Locke, the Enlightenment Free Essays

The idea of people as citizens rather than as subjects originates in 16th century Europe, during the Early Modern Period. During this period, European social order was in a state of flux as the rule of kings was confronted with a persistent and determined challenges defined by social forces that were pushing for more secular and democratic governments. There were both individuals and events that today may be seen as powerful drivers of those forces, and among them are John Locke, the Enlightenment, and the French Revolution. We will write a custom essay sample on Subjects to Citizens: Locke, the Enlightenment or any similar topic only for you Order Now As such a force, the Enlightenment, which began during the mid-17th century and remained a major political and philosophical phenomenon until approximately 1800, had tremendous impact in the rise and triumph of democracy over monarchy. The Enlightenment was catalyzed by the persistent discourse of a number of philosophers and historians, one of the foremost of which was John Locke. The magnitude of change introduced by the Enlightenment is rendered more clearly when viewing that period in context of the preceding era—the Medieval Period, during which the rule of kings prevailed, sustained by an embedded religious institutions that qualified the lineages of kings for ruler ship through divine ordainment. The Church enjoyed considerable reciprocity from the crowns by doing so, because rulers recognized the equity that religion held in the minds of their â€Å"subjects†, and found value in making mutually beneficial agreements with the church to preserve this closed loop cycle of maintaining and preserving a rigid social order. The losers of course were the â€Å"subjects† of those kingdoms, who ultimately had little say in who ruled them, and who were indoctrinated into a life of mute slavery and poverty, deprived of both education as well as the right to imagine upward social mobility, much less the access to opportunities to actually pursue such improved quality of life. It was the endpoint of these social dynamics, and the progressive deterioration of social responsibility throughout the dual leadership trees of church and crown, that catalyzed the French Revolution during the last decade of the 18th century. The French Revolution, in a nutshell, was the revolt of the long repressed peasantry against what they rightfully recognized as a corrupt governmental power cartel defined by the closed loop relationships between the crown and the Church. The French Revolution really punctuates the spirit of the Enlightenment, because the Enlightenment was all about waking people up to the notion that they had a right to select their leaders and that anybody was capable of exercising reason and logic in doing so, and most importantly that exercising those capacities was a much better answer to society’s problems than continuing to rely on superstitious belief in the right of a lineage of kings to continue ruling despite worsening social conditions. It was not until the French Revolution however that the Enlightenment really manifested full force. John Locke died nearly a century before the French Revolution, but he played a key role in developing the philosophies that activated and drove the Enlightenment, particularly through his composition of the Two Treatises. In these documents, he makes an effort to refute the notion that people do not have the capacity or knowledge or political understanding to select their own rulers. Locke’s philosophical arguments here really took those of opposing contemporaries like Sir Robert Filmer, whose viewpoints closely reflect the social order maintained by pre-Enlightenment establishment. Filmer’s Patriarcha: The Natural Power of Kings Defended Against the Unnatural Liberty of the People, a composition that presented arguments supporting the pre-existing social order of monarchic rule. The prevailing establishment justified monarchic rule through a number of arguments, both sociological and religious. Among these, they did so by arguing that a nation is like a family, with the population as the children as the king as the parent. Another argument was that to share the power of leadership in a democratic manner would be to invite and embrace the breakdown of social ethics, presumably because the natural disposition of a populace is to chafe under rules and laws and to desire more freedom, and that the endpoint of this would be excessive liberties, the deterioration of morality and ultimately the rise of an era where selfish and unjust rulers would take power. Rulers believed that the population simply could not, nor would they ever in a sustainable manner be capable of, responsibly selecting its own leaders. Locke challenged these ideas by introducing the concept of the Commonwealth, which would be defined by a social contract whereby the members of the Commonwealth participate in surrendering a certain level of liberty in order to ensure the stability of society and the preservation of the community. This surrender would only be the minimum required to preserve the peace, safety and security of the commonwealth, and part of this would involve the implementation of a democratic or republican system by which citizens would have at least a representative body in the government to ensure their needs were addressed. Notably, this was a key factor that activated in the French peasantry a desire to overthrow the First and Second estates, which they felt were taxing them without caring for their needs or interests.

Reflection on Hamlet Essay Example

Reflection on Hamlet Essay In regards to the Shakespearean play Hamlet, over the years as interpretations of a variety of elements have changed the structures, features and the timeless issues have remained similar in content. These timeless issues are untouched by context as the human condition and the quest for satisfaction has remained unfaltering. In relation to context there are two major differing contexts in which the play can be viewed. These are the Elizabethan viewpoint and that of todays society. To the Elizabethan audience the play of Hamlet was a text of moral instruction whilst the context of todays society is that Hamlet is the study of the individual. This essay will outline what has been learnt throughout the course of Hamlet with references to the two main differing contexts. The Elizabethan context conveys a theme of Christian Redemptive message where Gods plan always prevails no matter what obstacles were presented. Therefore sin was punished and virtue rewarded. My understanding of this is in Hamlet it is that of rationalizing of behavior before impulsive action that affirms the values of the era.

This shows Hamlets journey through the Christian message. Although the character of Hamlet procrastinates it is justified by his duty to God and religion. Through the quotes of or that the everlasting shows his devotion to God and fails to commit suicide. Another example is whilst Claudius is praying; although he fails to repent Hamlet is unable to murder him (whilst seeking vengeance) because Claudius appears to be repenting his sins. Hamlet is the study of the individual and how they attempt to balance internal desires and external pressures. Regardless of time/place the individual will always struggle with the balance of internal vs. external pressures. This is also apparent in Hamlet as the character Hamlet is unable to commit suicide as he has a duty to God. gainst self-slaughter. And thus he fails to suppress his internal desires too end it right now. Through humanity it is clear that there are many issues the individual face, these include suicide, duty, death and individuality/reality. These pressures provide the characters with a mean to express their viewpoints. In regards to the play, the characters of Polonius has suppressed his internal desires and replaced it with that of external pressures. He tells everybody what they want to hear as thus enables his own desires to be satisfied in an obscure manner. The quote very much like a whale, shows this and enables the audience to see the contrast in his character. The play has remained relevant over the years as the elements of human nature have remained constant. These elements include, quest for individuality, quest to understand death, quest for balance in life, pressures exerted on us both by internal and external forces. As human beings develop there is always a pursuit for satisfaction in life, the belief that there is something more to life than our selves. This is also apparent in the play Hamlet. When an audience member dwells upon the ideas that are present within the play, such as suicide, duty, illusion, death/heaven/hell, love, faith/religion it is clear that your personal understanding will make you question and re-think you ideas about them. To conclude it is clear that throughout time the themes, structure and relevance of the play has remained constant. The ever-changing values of the audience have changed, shifting the ideas that they bring forth thus creating new meanings. Although the play Hamlet can be seen in a variety of manners it is apparent that through the exploration of the characters/themes many new understandings of things in your own day to day life such as death/duty/reality enable us to perceive them in a more in-depth manner.

The Outsiders Essays (389 words) - A Day No Pigs Would Die, Film

The Outsiders Essays (389 words) - A Day No Pigs Would Die, Film The Outsiders A Day No Pigs Would Die Robert Newton Peck The book took place in rural Vermont with a young Shaker boy named Rob Peck. The novel was basically about this boy going through joyful and trying times in his youth, and his friendship with his pet pig named Pinky. Robert Peck was the main character, he was loving towards Pinky and he was obedient,( he knew if he wasnt, hed be in big trouble.) Throughout the book you could tell that his emotions were opening up more, now that he had a pet to love and take care of, yet he still held back some of his feelings. His father, Haven, was a good Shaker man and was a great neighbor. He cared for his son but was still stern in his own way, but he had to be, after all, he was a Shaker. Their neighbor, Benjamin Tanner, was grateful for Rob delivering The finest oxen in the county. Pinky was a gift from Mr. Tanner. To show his appreciation, he pulled out a pig from underneath his jacket and gave it to Rob. The theme of the book was traveling from boyhood to manhood and how quickly it came about. Through the short time the book took place, Rob turned from a boy into the man he is now. I think the first turning point was the death of Pinky and how he reacted towards that. The second instance was the death of his father and how he took it so well and even dug his fathers grave. When pinky died, he had a conversation that showed him turning into a man. He said, Oh, Papa. My hearts broke. So is mine, said Papa. But Im thankful youre a man. The second passage in the book describing manhood, is after Haven killed Pinky and said, Thats what being a man is all about, boy. Its just doing whats got to be done. Overall I liked this book, however, I didnt like the beginning. The author described the pain so well that I cringed as I read the passage about Apron. I even felt sad about the dog getting weaseled. The book was written well and the story was good, but Im just thankful that I didnt have to grow up that way. Bibliography none

Quebrada Jaguay - Terminal Pleistocene Archaeology

Quebrada Jaguay - Terminal Pleistocene Archaeology Quebrada Jaguay (designated QJ-280 by its excavator) is a multi-component archaeological site, located on an  alluvial terrace within the coastal desert of southern Peru, on the north bank an ephemeral stream near the town of Caman. At the time of its earliest occupation, it was about 7-8 kilometers (4-5 miles) in from the Peruvian coast and today is about 40 meters (130 feet) above sea level. The site was a fishing community, with a Terminal Pleistocene occupation date between about 13,000 and 11,400 calendar years ago (cal BP), based on a large suite of radiocarbon dates. Terminal Pleistocene sites are known in  Andean chronology as Preceramic Period I). The site is one of about 60 sites which have been found along the coast of Peru in this region, but it is the only one containing the Jaguay Phase occupations, and it is the earliest site in the region found to date (as of 2008, Sandweiss). The closest site with the same date is Quebrada Tacahuay, some 230 km (140 miles) to the south. It, like Quebrada Jaguay, is a seasonally-occupied fishing village: and those sites and many others extending from Alaska to Chile support the Pacific Coast Migration Model for the original colonization of the Americas. Chronology Late Preceramic Period, 4000 cal BP, Manos PhaseHiatus, 4000-8000 cal BPEarly Middle Preceramic Period, 8000-10,600 cal BP, Machas PhaseEarly Preceramic Period, 11,400-13,000 cal BP, Jaguay Phase During the Jaguay phase, the site was a seasonally-occupied coastal base camp for hunter-gatherers and fishermen who targeted mostly drum fish (Sciaenae, corvina or sea bass family), wedge clams (Mesodesma donancium), and freshwater and/or marine crustaceans. The occupations apparently were confined to the late winter/early summer months; the rest of the year, the people are believed to have moved inland and hunted terrestrial animals. Based on the size of the fish, the people were net fishing: the Machas phase occupations contain a few specimens of knotted cordage. The only terrestrial animals recovered from the site were small rodents, which were not likely food for the residents. Houses during the Jaguay phase were rectangular, based on the identification of postholes, and contained hearths; the houses were reconstructed several times in the same location but slightly different positions, evidence for seasonal occupations. Food remains and abundant lithic debitage were also recovered, but there were almost no finished tools. Poorly preserved plant remains were restricted to a few prickly pear cactus (Opuntia) seeds. The vast majority of the raw material for the stone tools (lithics) were local, but Alca obsidian identified by Instrumental Neutron Activation Analysis had been brought from its Pucuncho basin source in the Andean highlands some 130 km (80 mi) away and 3000 m (9800 ft) higher in elevation. Machas Phase The Machas Phase occupation at the site contains neither prickly pear nor obsidian: and during this period there are many more such villages in the region. The Machas phase occupation included several bottle gourd rind fragments; and a single semi-subterranean house, about 5 m (16 ft) in diameter and built with a foundation of mud and stone. It may have been roofed with wood or other organic material; it had a central hearth. The house depression is filled with a shell midden, and the house was also built on top of another shell midden. Archaeological Discovery Quebrada Jaguay was discovered by Frà ©dà ©ric Engel in 1970, as part of his investigations into the preceramic epoch along the coastline. Engel dated charcoal from one of his test pits, which came back to a remarkable 11,800 cal bp, unheard of at the time: in 1970, any site in the Americas older than 11,200 was considered heresy. Excavations were conducted at the site by Daniel Sandweiss in the 1990s, with a team of Peruvian, Canadian and U.S archaeologists. Sources Sandweiss DH. 2008.

Strategic Management in a Global Environment Assignment - 5

Strategic Management in a Global Environment - Assignment Example The paper tells that good governance means that all the authority and power is used in the most convenient way to uplift the performance of the institution without necessarily exploiting all the stakeholders and available resources. The secret of success lies in the power of the management team to utilize the strengths, weaknesses, opportunities, and threats to place the institution in a better functioning state. Good governance provides clear direction for the business institution. Transparency, fairness, accountability, planning, monitoring, and vigilance are the main building blocks of good governance. There is increased investment, boosted investor confidence, as well as interest. There is fairness in handling all stakeholders especially when there is good governance in a company. Good governance also strengthens the competiveness of the company besides making it cruise through the constant economic crises. Another benefit is scrapping off corruption and fund embezzlement, good g overnance has better strategies for conducting quality assurance programmes and giving comprehensive feedback for improvement in areas of weakness. The other side is bad governance; this is the true opposite of good governance. There lacks fairness, equity, responsiveness, transparency, effectiveness, and efficiency, in bad governance. In most case, bad governance precedes the downfall of a company. This means that the company is unable to survive the harsh and overwhelming market competition. Furthermore, many funds are misappropriated through lack of monitoring and evaluation. Bad governance is almost synonymous with poor planning and inadequate preparedness.

Understanding Microeconomics Issues Essay Example | Topics and Well Written Essays - 1000 words

Understanding Microeconomics Issues - Essay Example The essay "Understanding Microeconomics Issues" talks about the important role of microeconomics in the understanding of the relationship between the consumer, the producer and the trend in the market. There are important issues that must be understood in microeconomics and they include supply and demand, utility, and market failure and competition. All these issues are important to the understanding of the relationship between the consumer, the producer and the trend in the market. Their relationship provides the key to the understanding of economics. As goods and services are produced for sale, there are a number of factors that play a role in determining the prices at which the products will be sold. The backbone of any market economy and the most significant concept in economics is the supply and demand. Demand can be described as the quantity of a product or the services that are desired by the consumers. The amount of product that the people are willing to buy at a given price is the quantity demanded and its relationship with the price is referred to as demand relationship. Supply is described as the quantity of product and services that the market can offer. The amount of product that the producers are willing to supply at a certain price is the quantity supplied and its relationship with the price is referred to as supply relationship. An increase in the price of a commodity is accompanied by an inverse relationship in the quantity demanded, if all the other factors are held constant.

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

There are two main designs of telescopes

Astronomy can be defined as the study of all electromagnetic radiation from outer space. This definition encompasses the nature of the field, that the objects actually under study – the planets, stars, galaxies, et. al – are quite unreachable and such, information and knowledge we have of them stems not from direct experimentation but from observation of their emitted radiation.For most of astronomy’s history, that radiation was in the form of light and the primary tool for gathering and observing that light was the human eye. Without any aids, early astronomers such as Tycho Brahe, the Mayans and the Egyptians were able to develop a very detailed understanding of the stars and their motions.Ever since Galileo pointed his telescope towards the heavens, astronomy has been revolutionized. Far from being a study of celestial motions, astronomy evolved to the study of the actual celestial objects. The telescope allowed for direct observation of these specks of light traveling in the velvet sky.Moreover, the telescope allowed us to see what is impossible to perceive with the naked eye. Even the most basic telescope available today can reveal craters on the moon, or the moons of Jupiter and the rings of Saturn.There are two main designs of telescopes – reflecting and refracting. A telescope’s main function is to do one thing – gather light and focus it to one point. Refractor telescopes do this using lenses – curved pieces of glass which light passes through. The type of lens used by refractor telescopes are convex lenses which make parallel rays of light (emanating from the astronomical object) converge to a single point.The path of the light gets bent as it passes through the lens resulting in all the light rays being focused to a single point. In the case of reflecting telescopes, light is focused through the use of curved mirrors. Light being reflected by the mirror is directed to a single point. The shape of mirro rs used in reflector telescopes can include parabolas, hyperbolic and elliptical curves depending on the specific design of the reflector telescope.Today, the largest telescopes are all reflector telescopes. This is because to some inherent advantages in reflector telescopes. First, we need to realize that a telescope is a very precise optical device. With a reflector telescope, we only need to have one very precisely made side – the mirrored side of the glass reflector. Compare this to a lens where light has to pass through.A lens would have two surfaces which need to be perfectly polished, resulting in twice the amount of effort. Couple this with the fact that most contemporary refractor designs rely on multiple lenses to correct for optical aberrations. Secondly, reflector telescopes are more structurally sound at large sizes. Since light does not have to pass through the mirror, a support structure can be placed directly underneath the mirror.The support structure would b e much harder to create for a refractor telescope. Firstly, the shape of the convex lenses means that it is heaviest at the center. Secondly, even if it is heaviest at the center, the support structure can only be made at the edges due to the need for light to pass through the lens.As we said earlier, the primary purpose of a telescope is to gather light. A common misconception is that telescopes are used to simply make far away things look nearer, that is a telescope is supposed to magnify the view of objects. The magnification of a telescope is not a function of a telescope itself but a function of the telescope’s focal length and the focal length of the eyepiece used in viewing.The magnification is equal to the focal length of the telescope divided by the focal length of the eyepiece. This means that a single telescope can have many different magnifications depending on the eyepiece used. One might be tempted to think that telescopes can have infinite magnification simply by using eyepieces with shorter focal length.In reality, the highest magnification for a telescope is around 50 x the aperture (the diameter of the telescope’s objective optical element) in inches. This limitation is due to several factors. First, high magnifications will result in a dimmer image. Secondly, aberrations in the atmosphere and optical train become more obvious with high magnifications.Secondly, there is a limit to magnification as optical limitations would place a threshold on the available resolution produced by the telescope. Any magnification beyond this threshold only produces empty magnification as not additional detail can be resolved.The ability of the telescope to resolve details is inversely proportional to its aperture. This is set by the Rayleigh, Dawes and Sparrow’s limit which all say that the limiting resolution of an optical system is some factor divided by the diameter of the optic. Simply put, the larger the telescope, the higher its reso lving power.

Role Of The Dental Nurse And Measuring And Recording Root...

Q4) During a root canal treatment how do you assist the operator in measuring and recording root length? Why is this necessary? There are few ways how to measure length of root like placing single file in the root and taking radiograph or using apex locator. The role of the dental nurse is to make sure all necessary instruments and equipment are ready for appointment. What needs to be ready for radiograph method: x-ray machine + all chemicals for processing (if manual processing is used) or laser scanner (digital processing) + film; ruler, different lengths of files; file holder with sponge. What needs to be ready for apex locator method: apex locator with all wires and; different lengths of files; file holder with sponge. During procedure nurse is usually passing instruments, making sure equipment is set up and ready to go, assisting with taking radiographs, taking care about patient’s escort during taking radiographs, making sure patient is comfortable and calm, processing x-rays, also working length have to be recorded in the patient notes either paper or digital or both Correct length should be recorded for following reasons: - To be sure right size of gutta percha is choose in order to fill whole length of root canal except 2mm at the apex - For the second stage of root canal= it’s not necessary to re-measuring canal - Prevent perforating apex as this can lead to further problems - For the other dentist to be able take patient over - For the future references in theShow MoreRelatedHuman Resources Management150900 Words   |  604 PagesManagement After you have read this chapter, you should be able to: ââ€"  Identify four major HR challenges currently facing organizations and managers.
