Nuclear Power Plant
The fundamentals of the disaster While describing recent events which took place in Japan, I would like to tell a few words about the nuclear basics. First of all, I have to point out that the situation with nuclear power plant was under control. In other words, there were no defects of the equipment; so, the risk to the public was minimal.Advertising We will write a custom essay sample on Nuclear Power Plant specifically for you for only $16.05 $11/page Learn More There is a need to clarify that atomic fission was used as a heat source; no fossil fuel was used. When speaking about atomic fission, one is to understand that I am talking about uranium. Of course, one can suppose that the risk was really great as everybody is familiar with the situation in Chernobyl. However, in this case the nuclear chain reaction had to be uncontrolled. Such situation with nuclear power plant in Japan was impossible. Another major risk was associated with the process of o verheating. Taking into account the risks, I have to state that the plant was protected from regrettable consequences. The cladding, the reactor vessel, the containment building, and a dry-wall building were the barriers to protect the nuclear power plant. It is also necessary to admit that Fukushima used the reactors BWRs. Of course, engineers had a plan to prevent the consequences of the earthquake. Keith Yost (2011) says that, ââ¬Å"During regular operation, this chimney would be filled with a liquid/steam bubble mixture from the boiling water ââ¬â in an emergency, this volume can be packed with surplus coolant, effectively raising the thermal capacitance of the reactor vesselâ⬠(para. 8). So, one may ask what happened. At Friday, when the earthquake took place, ââ¬Å"the reactor automatically inserted its control rods into the core and ceased the fission of the nuclear fuel. Reactor power was at 6.5 percent, and full cooling was in effectâ⬠(Yost, 2011, para. 9). Unfortunately, the on-site generators were wrecked by the earthquake. These destroyed generators couldnââ¬â¢t activate the coolant pumps. Further consequences are well-known. The effects of radiation leak When earthquake in Japan took place, some articles concerning radiation leak at the nuclear power plant appeared. They said that radiation levels were increasing; however, authorities stated that there was no danger. Another interesting position, I would like to disclose is the similarities between the Chernobyl disaster and the disaster in Japan. Generally, I would like to point out that there were no similarities between two situations, as the disaster of 1986 was a man-made one; while the situation with nuclear power plant belonged to natural disasters.Advertising Looking for essay on other technology?

Radiation destroys the gastrointestinal system, the blood system, the immune system, etc. Moreover, it can cause cancer and genetic mutations. Jamie Epstein (2011) is of the opinion that, ââ¬Å"radiation can cause many harsh consequences to any form of lifeââ¬âwhether it be human, plants or animalsâ⬠(para. 2). Radioactive materials have different span of life. For instance, ââ¬Å"Strontium-90 is only radioactive for 53 days, Uranium-235 in the environment will remain radioactive for over 700 million years, Uranium-238 will remain radioactive for 4.5 billion years, and Rubidium remains radioactive for 47 million yearsâ⬠(Epstein, 2011, para. 6). When speaking about the global meaning of the disaster, Stephen Brozac and Henry Bassman (2011) state that, The worldwide implications of the event are becoming apparent: though a major leak in a maintenance pit of the plant has been plugged, there is still a great likelihood that significant amounts of radioactive water will continue to be released into the Pacific Ocean; the worldwide Just-In-Time manufacturingAdvertising We will write a custom essay sample on Nuclear Power Plant specifically for you for only $16.05 $11/page Learn More cycle has been interrupted; and increased levels of radiation have been detected on the U.S. East Coast (para. 2). The importance of safety While speaking about nuclear power plant construction several aspects must be taken into account. So, it is necessary to consider the construction cost of building, the operating cost, the cost of waste disposal, and the cost of decommissioning. However, the most important point, which must be taken into consideration, is safety of nuclear power plants. The major safety components include control of radioactivity, maintenance of core cooling, and maintenance of barriers. The last component is extremely important to prevent the spreading of radiation. According to Nuclearinfo.ne t, radiation doses at nuclear power plant must be thoroughly controlled. ââ¬Å"Monitoring of individual doses and of the work environment, limit on the time a worker spends in areas with significant radiation levels, physical shielding, and the handling of equipment via remote in the core of the reactorâ⬠(Nuclearinfo.net, 2012, para. 9) are recognized to be the most important procedures, which prevent radiation doses rising. Of course, it is necessary to regulate the neutron flux. To reduce the level of the radioactivity, it is necessary to reduce the neutron flux. If there is no opportunity to use water to cool the system, sodium or sodium salts can replace water. Thus, the chemical elements will be used as a coolant. Finally, it is better to build nuclear power plants away from towns, cities or villages.Advertising Looking for essay on other technology? Let's see if we can help you!

How to Start an After School Club
How to Start an After School Club A childs education does not take place only in the classroom, during regular school hours. The home, the playground, and the school campus, in general, can all be invaluable settings for a childs personal and scholastic growth. One way to enhance a students school experience is through extracurricular activities such as clubs. At the elementary school level, some appropriate, enjoyable, and educationally beneficial themes might be: Creative WritingBooks and ReadingChess and Other Board GamesOutdoor SportsCollecting and Other HobbiesMusic, Drama, and ChorusArts and Crafts (knitting, drawing, etc.)Anything else that fits the interests of your schools population Or, consider starting a club about the latest fad (for example, Pokemon a few years ago). Even though these extremely popular fads can also be annoying to adults, theres no denying that they do inspire boundless passion in the imaginations of a wide range of children. Perhaps, a Pokemon club could involve creative writing, original games, books, and songs about those colorful little creatures. Surely such a club would be bursting with enthusiastic young members! Now, once youve decided on the topic, consider the technicalities of starting a new club on campus. Here are some things to consider once youve determined the type of club youd like to start at your elementary school campus: Get permission from the schools administration to start the club on campus. Also, designate the time, place, and supervising adult(s) for the club. Look for commitment and set it in stone, if possible.Determine the age group that would be included as members of the club. Perhaps kindergarteners are too young? Would sixth graders be too cool for the concept? Narrow down your target population, and youll simplify the process right off the bat.Take an informal survey of how many students might be interested. Maybe you could place a half-sheet of paper in the teachers mailboxes, asking them to take a show of hands in their classroom.Depending on the results of the informal survey, you might want to consider placing a limit on the number of members to be initially accepted to the club. Consider the number of adults that will be able to attend the meetings to supervise and help out consistently. Your club will fail to meet its objectives if there are too many kids to handle effectively. Speaking of objectives, what are yours? Why will your club exist and what will it set out to accomplish? You have two choices here: either you, as the adult facilitator, can determine the goals all on your own or, at the clubs first session, you can lead a discussion of club goals and use student input to list them.Design a permission slip to hand out to parents, as well as an application if you are having one. An after-school activity requires parent permission, so follow your schools rules to the letter on this topic.Ã Make a concrete plan for the first day and subsequent sessions, as possible. Its not worth holding a club meeting if it is disorganized and, as the adult supervisor, its your job to provide structure and direction. The number one principle in starting and coordinating a club at the elementary school level is to have fun! Give your students a positive and worthwhile first experience with extracurricular involvement. By creating a fun and functional school club, you will be setting your students on the path to a happy and fulfilled an academic career in middle school, high school, and beyond!

Burkes Contributions to Rhetoric
This paper discusses Kenneth Burkes contributions to rhetoric and its importance as a communicative tool. This paper examines the history of rhetoric and its significance in early Greek and Roman civilizations that coincided with creation of democracy and the importance of public speech. It then shows Kenneth Burkes contribution to the new rhetoric as an argumentative weapon and his influence on the post-modern deconstructionism. Table of Contents 1. Introduction 2. Section One: The Preceding Conversation 3. Section Two: Contribution to the Conversation 4. Section Three: Effect on the Conversation 5. Conclusion From the paper: `The word `rhetoric` has an old fashioned air about it. It calls up images of schoolrooms with children in ruffled collars and Latin grammars and not a laptop in sight for several centuries. But rhetoric is as alive as is language itself, and this paper examines the importance of rhetorical studies in helping each of us to become the best writers and speakers ` the best communicators ` that we can be. A historical study of changes models and standards in rhetoric can also provide us not only with a sense of how linguistic and especially English style has changed over the years as well as illuminating how our conception of language and its structure and function have changed as well. This paper engages in such an examination by focusing on the work of Kenneth Burke. We begin with a brief overview of the life of this man whose rhetorical work we will then examine.`

The Market Education Assignment Example | Topics and Well Written Essays - 1500 words
The Market Education - Assignment Example This essay stresses that the market plays a major role in ensuring that the force of demand is equivalent to that of supply. In the case of museums, museum visits represent demand, while the number of available museums and museum services represent the supply. In a market, there is the aspect of price mechanism, which involves an interaction between the buyers and sellers, in order to determine the market price. Nonetheless, the market price is determined by the supply and demand in the market. Therefore, when prices rise, the demand falls, and when the prices fall, the demand rises. On the other hand, the market equilibrium price is achieved when there is a balance between the force of supply and that of demand. In this case, there results a balance in production and consumption of goods and services. Prices in a market economy can act as an incentive to entice buyers to purchase more goods. This report makes a conclusion that a demographic demand pattern for museum visits mainly depends on various aspects. First, the type of museum determines the type of visitors visiting it. The season also influences the nature of visits and types of visitors. For instance, Art museums might have many visitors, who are older, while science centers might receive visits from younger visitors. Furthermore, like art museums, historic sites and history museums might have older visitors. On the other hand, children museums are known to have the youngest visitors, as compared to art museums, history museums, and science centers.... Nonetheless, the entry fee to museums might be determined, depending on the level of demand. Therefore, at peak periods, when there are many tourists and domestic visitors, museums will increase their entry fees. 3. Museum Visits and Demographic Demand Pattern A demographic demand pattern for museum visits mainly depends on various aspects. First, the type of museum determines the type of visitors visiting it. Additionally, the season also influences the nature of visits and types of visitors. For instance, Art museums might have many visitors, who are older, while science centers might receive visits from younger visitors. Furthermore, like art museums, historic sites and history museums might have older visitors. On the other hand, children museums are known to have the youngest visitors, as compared to art museums, history museums, and science centers (Museum Audience Insight Web). 4. Shifts in Demand and Supply in Museum Visits Demand and supply with regard to museums is influenc ed by different factors. First, the national economy influences both the demand and supply of museum visits. During periods of recession, the amount of museum visits will decrease considerably (American Alliance of Museums Web). This is because, the purchasing power of consumers decrease, thus their spending on leisure and culture also decreases. The second aspect is that of entry or admission fee to museums. When the entry fee is increased, the demand will go down, but when the entry fee is lowered, the demand will increase, thus more museum visits. It can also be argued that the interest of people in their culture influences the demand in this market. The more interested people

Pfizer Case study Example | Topics and Well Written Essays - 250 words
Pfizer - Case Study Example In this way, without a lineup of potential breakthroughs in the pipes, the level to which the firm can continue to rely on cash cows that are soon to go off patent is severely constrained. As yet another example of the focus that the firm had on the development and introduction of runaway successes such as Lipitor, the firm had positioned itself as primarily a research and development organization that was hopefully able to introduce profitable drugs into the market on a regular basis as a means of ensuring that the profitability and cash flow of the company stayed intact. However, this positioning strategy was out of sync with market demands due to the fact that the rapidly evolving nature of other competitors meant that lower cost research and development was being performed by a host of competitors; thereby greatly reducing the profit margin and potential profit margins that such a runaway discovery such as Lipitor could yield. As a way to formulate strategy, the firm sought to integrate OTC markets and generic branding to its repertoire; however, the main money supply for the firm was still tasked towards developing new drug lines. This of course did not support t he strategic vision that leadership espoused. Though the strategic vision was sound, the lack of funding meant that it was not fully able to respond to the markets and the completive environment in which it hoped to

Global Education and Local Communities :: Teaching Learning Schooling Papers
Global Education and Local Communities Let me begin with a summary of what I am going to say. Cyberspace is a new kind of reality, in some crucial respects less real, but in some respects more real, than the space of face-to-face encounters and of physical documents. Signs in cyberspace might be quite unconnected to any real-life states of affairs, they might be quite abstract, but often they are much less abstract than, say, signs in a printed book. As I will endeavour to show, communication in the world of printed books is, characteristically, the communication of abstract meanings among members of an abstract society, such as a modern nation. The communication of knowledge in an interactive audiovisual medium is less dependent on an extended process of education in some national - i.e. literary - language than was the communication of abstract, typographical knowledge in earlier ages. Successful navigation in cyberspace does however presuppose some specific training leading to appropriate combinations of technical skil ls and literary skills, the latter normally encompassing both a rudimentary English and one's mother tongue. Working out how in fact such a combination of skills can be taught and acquired, and exploring the ways in which local communities can form a suitable learning environment, are the goals of an ongoing research program in Hungary; I conclude by sketching some essentials of this program. The Ontology of Cyberspace In some crucial respects cyberspace is, obviously, less real than the space of face-to-face connections. One should recall here GÃ ©rard Raulet's profound study "The New Utopia", written in the 1980s, pointing to the spurious idea of "supplanting places by spaces", and to the gap separating symbolic "interactivity" from actual social interaction.[1] And one should recall the essentially consistent findings of an impressive array of empirical investigations showing that telecommunications, however dense and multidimensional the networks, do not have the effectiveness, let alone the emotional impact, of face-to-face encounters. Until the late seventies, such investigations focused, understandably, on the effects of the telephone. What they found was that although telephone contacts did of course make a difference when no other contacts were available, [2] the former, as contrasted with face-to-face contacts, had no great propensity to create new linkages. Telephone contacts are effect ive if they can rely on background information from earlier personal meetings, and if they are regularly reinforced by such.[3] The same pattern still holds when e-mail and teleconferencing enter.

How Material Things Contribute Towards Differences on a Street Essay
Taking into consideration that ââ¬Ëdifference is not the same as inequalityââ¬â¢ (Blakeley et al., 2009, p. 24), this essay intends to look at KÃâ" and outline how the material things contribute towards differences with reference to City Road; deriving from the premise that the material assets of a street can generate either an inclusive or exclusive interaction, favouring some and not others. Kà ¶nigsalle, known by its nickname, ââ¬Å"Kà ¶, is the most beloved upscale commercial street in Germany (Welt online, 2010). On one side of the street we have stores from the most expensive brands in the world and on the other, a mix of baroque buildings which host a different number of businesses. Being seen walking along or visiting its stores is denotative of a unique social status. Everything along the Kà ¶ is designed to be in accordance to and promote an upscale social lifestyle. The material things on City Road, while performing a more literal function, also contribute to tangible objective differences when favouring, for example, pedestrians over drivers (e.g. the red tarmac offers pedestrians an extra safety measure when crossing, while taking away space from the drivers); parking is also a critical matter, generating therefore, economic consequences for the local shops (ââ¬ËMaterial Livesââ¬â¢, 2009, scene 1). Another relevant point is the fact that, City Road social appearance, along with its material assets usage, changes considerably throughout the day, making it almost a different street by nightfall (e.g. from a busy commercial street during the day to a ââ¬Ëparty havenââ¬â¢ at night, when it is taken over by young adults) (ââ¬ËMaking social lives on City Roadââ¬â¢, 2009, Scene 8). Such an absolute change does not occur on the Kà ¶. On the Kà ¶, the very same material things, should not only perform the most frugal of the functions, but also be in accordance to what the street stands for, thus, being an active part of the process of creating objective tangible differences -like in City Road, as well as, subjective ones. Kà ¶ supports its image by providing the necessary visible and invisible infrastructure to sustain a busy, high-octane upscale atmosphere: The street signage is visible; there are several crossing points; clearly marked sidewalks, tarmacs and lanes favour the mobility of handicapped individuals as well as bicycles and pedestrians without deterring traffic; it is well lit; the buildings and facades are well taken care of; litter bins are everywhere and one will, for example, find plenty of parking possibilities, which as a result, allows the individual to visit the stores and restaurants and feel safe. Altogether, the material things are in perfect apparent symbiosis with its users. Separately, each material asset on the Kà ¶ objectively indicates them as being part of a regular commercial street just like City Road. When looking at them altogether, the ensemble creates a striking subjective difference. To better illustrate how the material things on both streets subjectively enforces a certain type of behaviour and attitude, take the example of an individual walking down the street wearing shorts, tank-top and flip-flops. On City Road, this individual would most likely not even be noticed. The same individual walking down the Kà ¶, would be regarded as conspicuous. The same can be applied to the type of cars circulating on the Kà ¶ or City Road, a Ferrari on the Kà ¶ would be taken for granted while on City Road it would probably stand out. Another example to consider is parking. Though there are many parking slots and options, the prices around the Kà ¶ are up to 80% more expensive than other streets in Dà ¼sseldorf (RP Online, 2011), hence, favouring the visit of the more affluent layer of the community over the lesser one. There is no sign on the Kà ¶ telling who is welcomed or not; objectively speaking everyone is welcomed, but its material things are invested with such a subjective meaning, that they set the pace and shape of the local social life, creating therefore, an alluring environment which itself dictates a whole gamut of social patterns that are absorbed and followed by the local community, consequently contributing towards differences. While City Road reveals a more inclusive image, Kà ¶ conversely manifests a more exclusive one. As we can see, each street is similar in various aspects and are designed and structured to cater and favour a specific type of person, business or activity and its material things corroborate such a process by subjectively or objectively embedding certain social patterns which will then be adopted by their users.
