Solar Photovoltaic Cells Essay -- Solar Energy Heat Sun essays

Solar Photovoltaic Cells Solar energy is a general term referring to any process that turns sunlight into energy. Two common forms of solar energy are used today: Solar photovoltaic cells and solar thermal technology. Solar thermal technology uses the heat generated from sunlight to create energy. Most commonly, this can be used to heat water for a house or other projects. Or, with increasing complexity, it can turn the heat into electricity. Unfortunately, much of this technology is too expensive and complex to be practical in the United States on any large scale. However, solar photovoltaic cells are a far more promising technology. They provide a simple way of turning light directly into energy. This paper will examine how this technology works on a basic level while accessing the possible benefits and problems this technology has. It will also examine possible technology in the future in an attempt to overcome these problems. How solar photovoltaic cells work: A photovoltaic cell uses semiconductor material to transform light into electrical energy. Photons from light hitting the material excite electrons, releasing them from their atoms into the material. Once electrons are excited, they are able to move freely within the material. The semi-conductor then serves to force the electrons in the desired directions. By creating a junction of a p and n type semiconductor, an electrical potential is created. The electrons move from the n-type to the p-type. Meanwhile, the positively charged atoms move from the p-type to the n-type. As a result, the n-type material gains a positive charge and the p-type gains a negative charge. When an electrical circuit connects the p-type and n-type ends, difference in e... ...rrent conventional energy. It has promising chances of reducing carbon dioxide emissions and thus reducing global warming. But, it sill cannot compete economically with current energy means and as a result, more research must be dedicated into the cause in order for its benefits to be fully realized.

Evaluate the accuracy of “The Clouds” in portraying the political, social, economic and religious life of people in the fifth century BC Athens

Greek theatre has always been a significant constituent in the past and present Athenian society. Fifth Century BC Athenian society proposed numerous playwrights in their festivities honouring the god, Dionysus. Amongst the many crowd favourites was a legend to describe him in the least, Aristophanes. His works of satirical comedy are still celebrated and enjoyed today. One such example of his famous satirical works is â€Å"The Clouds†, written in 423BC. â€Å"The Clouds† is about a father, Strepsiades, who is in debt because of his son's expensive horse hobby. Strepsiades tries to convince his son, Pheidippides, to attend the â€Å"Thinkery† (a school for sophistry), to learn the art of double talk in the hope of outwitting his creditors in court. However, Pheidippides denies his father's request, so instead Strepsiades decides to enrol himself. Strepsiades' attempts to learn sophistry but fails miserably when his old age gets the best of him. Another attempt to encourage his son to enrol becomes successful and Pheidippides learns to double-talk from the teacher Socrates. This is later regretted when, at the climax of the story, Pheidippides uses double-talk to justify him beating his father. Strepsiades, out of anger and rage, then sets fire to the Thinkery. The main theme dealt with in the â€Å"The Clouds† is that of new versus old. Aristophanes challenges the radical thinkers like sophists and the imaginative thinkers like Socrates for oppressing the traditional values held and demoralising the youth. Another theme pertaining to â€Å"the clouds† is the confliction of religion and science. In fifth century BC, around the time when Aristophanes wrote the clouds, the commotion of â€Å"scientific theory† had just begun. With religion prevailing at the time, such atheistic thinking brought about by people like Socrates was firstly unlawful and secondly prone to ridicule by conservative figures such as Aristophanes. â€Å"The Clouds† is rather accurate in depicting Athenian life. However the perception of Socrates evident in the text is not parallel to that of Socrates in real life. Aristophanes, like many, linked Socrates with the rest of the Sophists for the reason that he was a philosophical thinker, that is, he came up with reasoning without relying on faith. However, Socrates, like Aristophanes rejected the ideas of the Sophists. The sophists argued that guiding principles of a society, such as justice and truth, varied according to the needs of men in a particular time and place. In teaching their students, the sophists emphasised the art of argumentative discussion and came to be associated with deceptive and hollow reasoning. This is depicted in the clouds where better argument represents traditional thinking and the worse argument depicts that of the sophists. Despite Aristophanes' rather critical portrayal of Socrates, the description of him as expressed through Pheidippides as † pale-faced charlatans, who haven't any shoes† is actually relatively true. Since Socrates wore simple apparel, and walked barefoot through the streets, his ideas and peculiarity made him an easy subject of derision and he was often thought of as a fraudulent figure. Socrates was also ridiculed for the fact he believed in one intelligent being as the creator of the universe. This went against the religious life of the Athenians. In â€Å"The Clouds†, Poseidon, god of horses is sworn on by Pheidippides and later again by Pasias (one of Strepsiades creditors) who also swears by Hermes and Zeus. These accounts are an accurate reflection the religious beliefs upheld by Athenian society. However, since â€Å"the clouds† is a satirical play, Aristophanes pokes fun at Socrates who is depicted to believe in the â€Å"vortex† as the ruler, not Zeus. This part of the play is not accurate, as it does not hold a factual purpose but rather that of entertainment and humour. Rather than just analysing â€Å"The Clouds† on its plot, a more comprehensive read of the text reveals further details on 5th century Athenian life, all of which are precise in information. For instance, it is apparent in the text that concepts such as creditors, debtors and interest, were already in use at the time. This shows that Athenian society had in place forms of financing that still exist today. Also, there is a clear depiction of the judicial system present at the time. It is evident in the text that when taking a person to court a deposit must be made and if the case was lost the deposit was forfeited. Other instances in which â€Å"The Clouds† has effectively portrayed Athenian life is through their currency, such as drachmas and obols and also in their legal system, when the Better Argument makes reference to the punishment of adultery, this being having a radish shoved up his anus and his pubic hair singed with hot ash. The people of the 5th century BC Athenian society were rather wealthy and could afford slaves. The polarisation of the two classes of people within society is portrayed rather well. This is evident with Strepsiades' servant Xanthias who lives an unpleasant life when compared to Pheidippides who indulges in the costly hobby of buying racehorses. This is further exemplified when Pheidippides mother insists to add -hippos (meaning horse) to Pheidippides name at birth so he could have the marks of the aristocratic classes. In conclusion, â€Å"The Clouds† is a satirical play and should not be taken for face value. However, his portrayal of issues and figures within the society give an accurate insight into some of the beliefs held by the general public and if treated carefully could be considered as reliable historical source. A serious theme underlies this comedy, namely: Ideas espoused by radical thinkers like the sophists and by highly imaginative thinkers like Socrates are undermining traditional values and corrupting the morals of youths. The sophists maintained that the guiding principles of a society, such as justice and truth, were relative concepts-that is, these principles changed according to the needs of men in a particular time and place. What was right and just in Athens was not necessarily right and just in another society. One man's virtue could be another man's vice. In teaching their students, the sophists emphasized the art of argumentative discourse and came to be associated with deceptive and specious reasoning, lampooned effectively in The Clouds. Another target of Aristophanes was Socrates, along with his associate, Chaerephon. Ironically, Socrates, like Aristophanes, renounced the methods and ideas of the sophists. Nevertheless, Socrates angered the establishment (1) by declaring that the validity of many long-standing precepts could not be proved by logical reasoning, (2) by rejecting the Olympian gods and sometimes speaking of a single intelligent being as the creator of the universe, and (3) by spreading â€Å"dangerous† ideas among young people. In addition, he alienated many Athenians because he was ugly and untidy (sometimes neglecting to bathe for a long while), wore simple apparel, and walked barefoot through the streets. Thus, his ideas and eccentricities made him a ripe subject for ridicule.

A small fraction of the smuggled goods and illegal services may nevertheless be included in official trade statistics through dummy shipments or dummy declarations that serve to conceal the illegal nature of the activities. Balance of trade Balance of trade represents a difference in value for import and export for a country. A country has demand for an import when domestic quantity demanded exceeds domestic quantity supplied, or when the price of the good (or service) on the world market is less than the price on the domestic market. The balance of trade, usually denoted NX, is the difference between the value of the goods (and services) a country exports and the value of the goods the country imports: NX = X − I, or equivalently I = X − NX A trade deficit occurs when imports are large relative to exports. Imports are impacted principally by a countrys income and its productive resources. For example, the US imports oil from Canada even though the US has oil and Canada uses oil. However, consumers in the US are willing to pay more for the marginal barrel of oil than Canadian consumers are, because there is more oil demanded in the US than there is oil produced.

General Characteristics of Battered Woman Syndrome

Battered Woman Syndrome An estimated 1.3 million women are victims of physical assault by an intimate partner each year. A surfacing psychological condition known as Battered Woman Syndrome (BWS), develops after experiencing physical and emotional abuse over an extended period of time. BWS has been subcategorized as a form of post-traumatic stress disorder, proving that it is indeed, a very serious and severe condition. Battered Woman Syndrome causes severe, emotional and psychological trauma in women after prolonged abuse in an intimate relationship; the number of Battered Woman cases in America is rising each year and it is necessary that more attention be brought to its significance as well as the victims being effected. More†¦show more content†¦Women stay because sometimes, they have nowhere left to go. She stays because she believes that maybe, the man she once loved will stop the abuse. Women stay in these abusive relationships because they are trapped and they are helpless. The question is not why do these women stay, but why do these men feel the obligation and audacity to batter them. Even when the cycle of abuse seems endless, however, there are ways to help and treat a victim of domestic violence or more so, a battered woman. First of all, safety must be established. For a battered woman, even hinting towards divorce or a break-up with the batterer can be the most unsafe time. Secondly, a treatment plan and or trauma therapy should be considered to ensure a safe recovery for the victim of abuse. Therapy can be a very powerful tool in helping victims heal after abuse.

The War of Americans Free Essays

Over the course of the last half-century the U. S. has enjoyed unprecedented power in every aspect whether it be politically, economically, militarily, or by any other means. We will write a custom essay sample on The War of Americans or any similar topic only for you Order Now In its dominance of world politics since WWII, the U. S. has been able to cast its influence around the globe. However, the U. S. experienced a gradual decline in its sovereignty over the course of this era as well. A prime example was in 1973 when OPEC raised oil prices drastically over the course of the next two years. â€Å"OPEC†s ability to increase at will the world price of its precious product highlighted the industrial world†s dependence on foreign sources of energy. (Keylor, p. 346) Being a sovereign nation requires not being subject to external forces, being able to conduct an independent foreign policy, and being able to control events within your own borders. Today, U. S. sovereignty continues to decline for a number of reasons. The only question is whether it is healthy or harmful for the U. S. to do so. The first reason why U. S. sovereignty is declining is due to what is known as interdependence. This phenomenon developed after WWII with the creation of the UN, GATT, the IMF and other such intergovernmental organizations. All of these served to create linkages between the major nations of the world in the postwar era. Membership in such organizations makes the U. S. subject to international law. Rosecrance†s identification of the trading state signifies the shift away from geopolitical influence and towards a global economy. Both the roles of international trade and foreign investment have increasingly become a greater element of U. S. economic importance. Additionally, the tying together of economies from around the world has lead to an increase in economic warfare. The increased use of economic sanctions and other such measures can be contributed to their perceived effectiveness in obtaining foreign policy goals. The U. S. integration into the world economy leaves it susceptible to the economic decisions of its trading partners and providers of raw materials. Reliance on import and export goods is an essential part of the U. S. economy. This can be seen in every day life. Just think about how much gas prices have increased recently as the result of a few nations restricting their oil supplies in order to raise prices. While the countries responsible for this could all be readily defeated by the U. S. in war, the U. S. is powerless to combat their practices. Aside from its place in the world market, the proliferation of weapons of mass destruction also serves to limit the sovereignty of the U. S. First off, new nuclear powers, which would likely include a number of aggressive authoritarian states, will lack the resources to manage the elaborate command and control capabilities required. â€Å"Even if hostile countries somehow catch up in an arms race, their military organizations and cultures are unlikely to catch up in the competence race for management, technology assimilation, and combat command skills. (Betts, p. 29) In addition to proliferation of nuclear weapons, there is also wide concern among U. S. leaders about the spread and development of biological weapons. The rise of religious nationalism and anti-U. S. sentiments in nations such as Iraq give cause for concern to the U. S. that an attack using biological weapons is possible. â€Å"One simple fact should worry Americans more about biological than about nuclear or chemical arms: unlike either of the other two, biological weapons combine maximum destructiveness and easy availability. † (Betts, p. 32) Even more threatening to U. S. sovereignty is the treat of terrorist attack to our nation†s soil. The proliferation of the aforementioned weapons is worrisome to U. S. officials that a horrendous nuclear of biological terrorist attack is feasible. The possibility of such and attack places a serious hindrance on the U. S. ability to protect its citizens within its borders. Conspirators of such an attack could be based within the U. S. or abroad, which makes it increasingly difficult to guard against. Additionally, it is impossible to deter such a course of action. When a nation is attacked, the government behind the attack is readily identified and a counterattack can be undertaken. However, when it is unknown as to who is behind the attack, it makes it impossible to deter it from occurring since â€Å"retaliation requires knowledge of who has launched an attack and the address at which they reside. † (Betts, p. 34) Such concerns have increased since the end of the Cold War as there is widespread doubt surrounding the degree of control Russia used in disposing of their nuclear weapons. The information revolution also poses a serious threat to U. S. overeignty. The increasing opportunities for interaction through technological advances in communications and transportation make information more readily accessible. The strong reliance on the behalf of the U. S. on information infrastructure makes it vulnerable to attack. (Wriston, p. 179) â€Å"The smallest nation, terrorist group, or drug cartel could hire a computer programmer to plant a Trojan horse virus in software, take down a vital network, or cause a missile to misfire†¦ The United States† increasing reliance on massive networks may make it more, not less vulnerable. † (Wriston, p. 80) As with the problem of an armed terrorist attack, it is extremely difficult to determine who is responsible for a break-in of a private, supposedly secure, U. S. government web page. Fortunately, we have not yet witnessed any such form of information warfare; however, imagining the form it might take and protecting against it has become the preoccupation of a presidential commission and numerous task forces. (Wriston, p. 179) Despite the erosion of U. S. sovereignty, it is still by far the most powerful nation in the world today. I for one would welcome the erosion of U. S. overeignty since it furthers interdependence in world politics and serves to perpetuate world peace. The greater the economies of the world are intertwined, the less likely it is that a nation will go to war with another that it is linked to by a web of transnational relationships. It may also be in the best interests of the U. S. to lose some of its sovereignty since the world is moving towards civilizational entities (Western, African, Islamic, etc. ) as identified by Samuel Huntington. (Huntington) If he is correct in his prediction, then the U. S. is better off belonging to one of these civilizations rather than standing alone. How to cite The War of Americans, Essay examples

Cause/Effect of immigration reform free essay sample

What is the first thing that comes to mind when you think of immigration? What is the United States’ current Immigration Policy? Would you even think that it is considered to be one of the most debatable topics today? Nowadays, many people decide to immigrate to have a better life for themselves and their families. Immigration reform, as it has been called, had been tried during the past years by our very own Congress. Obviously, administrations efforts failed because, currently, illegal immigration is still a platform. Why would anyone expect that immigration reform would be accomplished this time around? The illegal problem will solve itself over time. Illegal immigration is a serious problem in the United States and is one of the most controversial issues. During the 1980s and 1990s, illegal immigration was a round-the-clock issue for â€Å"political debate,† as immigrants continued to immigrate to the United States, mainly through Canada and Mexico. We will write a custom essay sample on Cause/Effect of immigration reform or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In the beginning of the 1960s, immigration reform had heightened because of the civil rights movement going on in the United States. According to U. S. Immigration Since 1965 published on history. Com, the reason for change is that â€Å"immigration [is] based on the national-origins quota system in place since the 1920s, under which each nationality [is] assigned a quota based on its representation in past U. S. census figures. † In the year 1996, Congress issued two reforms that â€Å"addressed border enforcement and the use of social programs by immigrants. † Most recently, since the tragic event of 9/11, the Homeland Security Act of 2002 founded by the DHS (Department of Homeland Security), â€Å"which took over many immigration services and enforcement functions formerly performed by the Immigration and Naturalization Service (INS)† (U.  S. Immigration Since 1965). There are many causes of immigration to the United States. The United States has been described as a nation of immigrants, where people of many different races, religions, and cultures have mixed together to form a society. According to Root Causes of MigrationFact Sheet published on wear eoneamerica. org, the main reason for immigration is â€Å"poverty†, wars, social disagreement, political disorder, and â€Å"economic hardship. † On the other hand, Top Seven Reasons Why People Immigrate, published on immigration.  net. in on July 9, 2009, states the top seven reasons for immigration is a â€Å"financially secured future, high standard living, education, start of a series, political reasons, needs for different personalities, and a soul mate. † For example if someone is wanting a financially secured future they would emigrate to a country that has â€Å"higher wages† and a better future. Moreover, a job that has increased pay or a living situation that is far better than the one in their original country. To explain the â€Å"start of a series† reason, the website says that once a family or friend sends letters or postcards to someone in another country of how good they are doing, then that person will want to go there as well. For the political reasons, some people think they do not have enough political freedom. Some come to the U. S. to get political rights and others for a better living atmosphere. Furthermore, they immigrate to other countries in search of altering to their citizenship for a â€Å"new identity† (Top Seven Reasons Why People Immigrate). Illegal immigrants entering the United States have played a major impact on the quality of life in our economy. Positive effects include taking jobs that Americans would not normally want, such as â€Å"retail, cleaning, food preparation, construction, and other services. † In doing this, they help the economy make affordable â€Å"priced goods† and raise the actual wages of most Americans (Griswold). Also, immigrants start their own businesses. According to the Partnership for a New American Economy, in 2011, immigrants started 28 percent of businesses. More importantly they make jobs for Americans. Furthermore, immigrants raise the requirements for â€Å"local consumer goods. † The 2010 American Community Survey states that â€Å"immigrants earned a total of $1. 1 trillion, and the Immigration Policy Center estimates that the purchasing power of Latinos and Asians, many of whom are immigrants, alone will reach $1. 5 trillion and $775 billion, respectively, by 2015† (Immigration and the Economy). All in all, maybe immigrants are not as bad as everyone thinks. For centuries, people have come across the United States borders from foreign countries hoping for a better life wanting to live in the land of opportunity to make something of themselves; this is why we have major problems with illegal immigration. Immigration negatively impacts our country so much that â€Å"the CBO estimated that federal spending would increase $53. 6 billion during the period 2007- 2016 if the legislation became law, primarily because of increases in refundable tax credits and Medicaid spending. † This cost is compared to the gains of the U. S.  economy from a more diverse supply of workers and a wider range of more affordable goods and services for genuine Americans. Expanded illegal immigration has also been accused for congested roads, full hospitals, public schools, and packed prisons. On a national level this has been overemphasized by advocates of immigration reform, but can be a real problem at the local level. â€Å"[A]lthough the fiscal impact of a typical immigrant and his or her descendants is strongly positive at the federal level, it is negative at the state and local level,† expressed the 1997 National Research Council study. By stating this, it shows that there will be a higher net cost of the state government in billions (Griswold). Many of the problems associated with illegal immigration could be solved if the existing laws in the books were enforced. To some, it might seem like an impossible task to stop the flow of illegal immigrants across the border, but many could probably be discouraged to cross the border illegally if our government was strictly enforcing the law. From the early 1900s the government has witnessed and tried to help with the illegal immigration and the immigration reform.
