Nuclear Power Essays (2330 words) - Nuclear Technology,

Nuclear Power The world's natural resources are being consumed at an alarming rate. As these resources diminish , people will be seeking alternative sources by which to generate electricity for heat and light . The only practical short term solution for the energy-crisis is nuclear power. Nuclear power, however is not as safe as burning coal, gas or oil in a factory it is in fact , much more dangerous, There are dangers associated with a nuclear power plant which far out weigh the benefits to society as a whole and in part to the community living and working around the power plant . About 20 percent of our nation's total electrical consumption per year is supplied by nuclear power from the 100 or so nuclear power plants throughout the country . Even though atomic power has been in use for over 50 years it was primarily a tool of war and destruction when the war ended need for atomic bombs diminished . The scientists who created the weapons were out of jobs . They then turned this destructive power into huge plants generating clean and cheap electricity for the country . It was called progress. Progress also brought with it sickness , mutations , cancer and eventually death to those exposed to high levels of radiation . Government declared that nuclear power is safe and efficient . Also have big Oil corporations who have a lot of money invested in nuclear power and want to see as many plants as possible put into and kept in operation . The truth is that accidents do happen at nuclear power plants and at other facilities all the time . An accident at a nuclear power plant has the potential to be much more devastating than an accident at a coal or gas plant because of the radiation that could be released . An example of this is Three Mile Island in Pennsylvania where there was a partial core meltdown in march of 1979 and an acceptable amount of radiation escaped into the atmosphere . However no amount of radiation is acceptable if released as a result of an accident at a nuclear power plant . Is Nuclear Power necessary ? Today many Americans adopt lifestyles that are based on energy in-efficient devices . These include large automobiles and electric appliances that require electricity from energy-intense industrial processes . The public is doing all it can to force nuclear power plants into production by wasting electricity and the resources which are used to produce it ( coal , oil , gas) and by failing to recycle . Nuclear power has been promoted world-wide as economically advantageous and necessary to replace fossil fuels as the means of energy production in the 21st century . However this is untrue . There are many other economically viable and environmentally safe methods of producing energy .These include solar power , hydroelectric power and wind power . Today one fifth of the world's total energy production either comes from either wind ,water or solar power . It is estimated that by the year 2000 forty percent of the world's energy production will be from sources other than fossil fuels or nuclear power .It is estimated that to meet , via nuclear power a quarter of the projected U.S. primary power demand in the year 2000 that the US would have to order a new nuclear power plant to be built every five days to compensate for the irradication of the coal , oil and gas powered plants . On the other hand if all U. S. nuclear power plants were shut down now , it would not make any difference at all . The existing electrical backup systems have reserves of power that can more than make up for the loss of the nuclear power plants . The nuclear power plants that are in use today are no more than large plants serving no purpose at all and endangering many peoples lives . Is Nuclear Power worth the risks ? With any large energy producing facility there are risks . The risks posed by a nuclear power plant however , are far greater than those posed by any other . Meltdowns, cancer ,

Nihonium Facts - Element 113 or Nh

Nihonium Facts - Element 113 or Nh Nihonium is a radioactive synthetic element with the symbol Nh and atomic number 113. Because of its position on the periodic table, the element is expected to be a solid metal at room temperature. The discovery of element 113 was made official in 2016. To date, few atoms of the element have been produced, so little is known about its properties. Nihonium Basic Facts Symbol: Nh Atomic Number: 113 Element Classification: Metal Phase: probably solid Discovered By: Yuri Oganessian et al., Joint Institute of Nuclear Research in Dubna, Russia (2004). Confirmation in 2012 by Japan. Nihonium Physical Data Atomic Weight: [286] Source: Scientists used a cyclotron to fire a rare calcium isotope at an americium target. Element 115 (moscovium) was created when the calcium and americium nuclei fused. The moscovium persisted for less than one-tenth of a second before decaying into element 113 (nihonium), which persisted for over a second. Name Origin: Scientists at Japans RIKEN Nishina Center for Accelerator-Based Science proposed the element name. The name comes from the Japanese name for Japan (nihon) together with the -ium element suffix that is used for metals. Electronic Configuration: [Rn] 5f14 6d10 7s2 7p1 Element Group: group 13, boron group, p-block element Element Period: period 7 Melting Point:  700  K  Ã¢â‚¬â€¹(430  Ã‚ °C, ​810  Ã‚ °F)  (predicted) Boiling Point:  1430  K ​(1130  Ã‚ °C, ​2070  Ã‚ °F)  (predicted) Density:  16  g/cm3  (predicted near room temperature) Heat of Fusion: 7.61 kJ/mol (predicted) Heat of Vaporization: 139 kJ/mol (predicted) Oxidation States:  Ã¢Ë†â€™1,  1,  3, 5  Ã¢â‚¬â€¹(predicted) Atomic Radius: 170 picometers Isotopes: There are no known natural isotopes of nihonium. Radioactive isotopes have been produced by fusing atomic nuclei or else from the decay of heavier elements. Isotopes have atomic masses 278 and 282-286. All known isotopes decay via alpha decay. Toxicity: There is no known or expected biological role for element 113 in organisms. Its radioactivity makes it toxic.

Find MBA Case Studies From Top Business Schools

Find MBA Case Studies From Top Business Schools Many business schools use the case method to teach MBA students how to analyze business problems and develop solutions from a leadership perspective. The case method involves presenting students with case studies, also known as cases, that document a  real-life business situation or imagined business scenario. Cases typically present a problem, issue, or challenge that must be addressed or solved for a business to prosper. For example, a case might present a problem like: ABC Company needs to increase sales substantially over the next several years to attract potential buyers.U-Rent-Stuff wants to expand but is not sure whether they want to own the locations or franchise them.Ralphies BBQ, a two-person company that makes spices for BBQ products, needs to figure out how to increase production from 1,000 bottles a month to 10,000 bottles a month. As a business student. you are asked to read the case, analyze the problems that are presented, evaluate underlying issues, and present solutions that address the problem that was presented. Your analysis should include a realistic solution as well as an explanation as to why this solution is the best fit for the problem and the organizations goal. Your reasoning should be supported with evidence that has been gathered through outside research.  Finally, your analysis should include  specific strategies for accomplishing the solution you have proposed.   Where to Find MBA Case Studies The following business schools publish either abstracts or full MBA case studies online. Some of these case studies are free. Others can be downloaded and purchased for a small fee.   Harvard Business School Cases - Harvard offers thousands of case studies on every business topic imaginable.Darden Business Case Studies - Thousands of MBA case studies from the Darden Graduate School of Business Administration at the University of Virginia.Stanford Case Studies - A searchable database of MBA case studies from Stanfords Graduate School of Business.Babson College Case Studies - A large collection of business case studies from the Babson faculty.IMD Case Studies - 50 years of case studies from the IMD faculty and research staff. Using Case Studies Familiarizing yourself with  case studies  is a good way to prepare for business school. This will help you familiarize yourself with various components of a case study and allow you to practice putting yourself in the role of a business owner or manager. As you are reading through cases, you should learn how to identify relevant facts and key problems. Be sure to take notes so that you have a list of items and potential solutions that can be researched when you are done reading the case. As you are developing your solutions, make a list of pros and cons for each solution, and above all, make sure the solutions are realistic.

Nutrition Science with menu I created Assignment - 1

Nutrition Science with menu I created - Assignment Example When ordering, you will not order partial cases. For example, if you need 8 No 10 cans, order two cases. Plan a one-day menu including serving sizes from the foods listed at the end of this document. When a food is portioned to be an individual serving in the list included in this assignment, use that as the serving size. For example, dry, uncooked cereal is on the list in single serving boxes/cartons that range from 0.75 to 1.375 ounces. If you use one of them as a menu item, the serving size will be the same as the weight on the list. For other foods, Table 2.4 (12th edition) in Food for Fifty or 4.1 (13th Edition) is very helpful in determining some serving sizes. For example, nearly all vegetables, which are typically portioned with a number 8 dipper, i.e.,  ½ cup, are listed in the table as being a 3 oz portion. This means they weigh 3 oz. This does not mean 3 fluid ounces. USE FORM 1 FOR YOUR MENU PLAN. Failure to use the form will result in a 5 point deduction. You will need to prepare a purchase order for the foods and ingredients you need to serve your newly planned menu to 50 people. Use the attached form, FORMAT FOR DETERMINING PURCHASE INFORMATION, Form 2. The list of foods includes the price. It will also indicate the size of an institutional package/case and the contents of the case. 1. Using FORM 2, list all the menu items including any ingredients you will need to make the menu item in the first column. For example, in the sample, for scrambled eggs, both eggs and milk are listed. Then in the second column, list the amount you will need to make 50 servings. If you need a partial can or package please indicate that in the column titled Quantity to serve 50. If the product comes in 1 oz or approximately 1 oz (cereal) or 4 or 6 oz portions (juice, pudding, yogurt, etc), indicate in the â€Å"Quantity to serve

Darwin Natural Selection Essay Example | Topics and Well Written Essays - 750 words

Darwin Natural Selection - Essay Example As the paper highlights  one of the issues that creationists and individuals that believe in intelligent design point to as a shortcoming of natural selection is with respect to those organisms or systems that are highly complex and in which partial inadequacy of function would preclude natural selection.   One such system would be that of the human eye; arguably one of the most complex mechanisms that exists within nature.   However, Darwin, and those that support him would point to the fact that the need to see would be evidenced through many of the different states of eyesight that exist from the most basic caterpillars to the most advanced mammals.   Although it is true that the theory itself exist on something of an extension basis, the understanding and believe that the validity and truth of the statement ultimately exists as a function of its existence, there are a number of moral parallels and understandings that can be constructed via immoral understanding of specifi cally what Darwin’s theory entails.This paper outlines that  without the four a higher power, morality and another itself is constrained only with regards to the way in which humanity seeks to buy morality within the current context. In other words, natural selection in and of itself is a process by which furtherance of species is sure by the natural and â€Å"blind† process that nature engages to select those which will most likely carry on genes further the process of reproduction.

Studied male behaviour Essay Example for Free

Studied male behaviour Essay One type of gender bias is alpha bias. This is the tendency to exaggerate differences between males and females. An example of this is heightening the value of women (e.g. Gilligans theory of moral development), and a contrasting example is devaluing them (e.g. Freuds theory of psychosexual development, which says that women develop inferior superegos). Another type of gender bias is beta bias, which is the tendency to overlook differences or exaggerate similarities between the sexes. This was an issue in Kohlbergs theory of the development of moral understanding, as his classifications were largely based on justice-based morality for both men and women, when it may be that women have different moral values. Many psychological studies have been criticised for being androcentric. An example of this is Milgrams (1963) research into obedience. This bias was particularly methodological: he used only male participants, meaning that it is possible that the findings only apply to males and do not generalise to females. This criticism is supported by a replica study by Kilham Mann (1974), who used both male and female participants, 16% of the female participants obeyed and administered the full shock, compared with 40% of the males. This significant difference was overlooked by Milgrams study as he only studied male behaviour. Both of these pieces of research were conducted in a laboratory setting, which is criticised by feminists for being a male-dominated environment that disadvantages women and feminine behaviour: this may have influenced how some of the participants in both studies acted, in that they may have otherwise acted differently if the setting was more natural. The feminist criticism would suggest that, in Kilham Manns study, less women would obey in real life; however this criticism may itself be criticised for alpha bias and reductionism, since it may be too simplistic to characterise behaviours and settings as masculine or feminine. A theory criticised for its alpha bias is the sociobiological theory of interpersonal attraction. The theory states that males and females look for different characteristics in either sex, and will emphasise certain aspects of their own characteristics in order to attract a partner of the opposite sex. Dunbar (1995) compared around 900 lonely hearts advertisements from four newspapers in the United States, and found that 42% of males sought physically attractive characteristics in their partner, compared to 22% of women; and 50% of females adv ertised their own physical attraction, compared with 34% of males. Their conclusion was that the theory was supported and, while this is true to a certain extent, it overlooks the fact that the theory holds true for a maximum of 50% of participants. That is, it was not all males and no females who said that they sought a physically attractive partner. The research therefore demonstrates the alpha bias of both the theory and Dunbars conclusions. In addition, the sample and setting of the theory may produce alpha bias. It may be that dating agencies augment gender differences in order to optimise success rates, even if this is not representative of real life. Subsequently, people submitting their own advertisements may conform to this norm of augmenting their own gender, therefore leading to a biased sample and, therefore, biased results. This research could be improved by using a more representative sample, such as using a random sample from a wide range of places for a questionnaire. This is especially important since the sociobiological theory is an evolutionary theory, in that it assumes that our desires are innate: it is therefore important to gain a sample from multiple cultures. Numerous other theories and research have been criticised for their gender bias. Freuds psychosexual theory of development is particularly vulnerable to this criticism, as it is androcentric. He claimed that women have inferior superegos to men because they do not have a penis, leading to penis envy which would never be fully resolved. In other words, the theory suggests that femininity is a sort of failed masculinity. This is contrary to the widely accepted idea that women and men, despite their differences, are equal; and even Freud (1925) admitted his gender bias, saying that we must not allow ourselves to regard the two sexes in completely equal in position and worth. In reaction to this, Homey (1926) said that it did not make sense that women would envy a mans penis, instead envying their higher social status (at the time). Horney also coined the term womb envy, which describes a mans envy of women for their ability to have children, therefore providing a less androcentric view by indicating that men and women are different and envy each others positive characteristics. Kohlbergs (1976) theory of moral development has been criticised for beta bias and androcentricism. In his research, he presented participants with moral dilemmas and categorised them with respect to how much they had matured morally based on their responses to the questions subsequently asked. However, this may be seen as androcentric due to the criteria required for categorisation: the dilemmas were based on abstract principles of justice, which Gillian (1982) proposed was an inherently male method of thinking. This meant that Kohlbergs findings classified most women as being morally inferior to men because of the beta bias of the theory. Gilligan (1982), instead, proposed that womens morals are based on care and relationships, whilst those of men are based on justice. However, this theory shows alpha bias, and the existance of this bias is demonstrated by her own findings that roughly as many women base their morals on justice as on care. In fact, Walker (1984) found, in a meta-analysis of 108 studies, that only 8 studies showed overall gender differences in morality (which, ironically, displays beta-bias).  It may be that the alpha- and beta-bias in such studies arise due to a lack of explanation of individual differences, as it is rarely the case that there are no differences between men and women, or that men and women are completely different.

Employability Skills:An Update :: Employer Work Job Essays

Employability Skills: An Update This project has been funded at least in part with Federal funds from the U.S. Department of Education under Contract No. ED-99-CO-0013. The content of this publication does not necessarily reflect the views or policies of the U.S. Department of Education nor does mention of trade names, commercial products, or organizations imply endorsement by the U.S. Government. Digests may be freely reproduced and are available at http://ericacve.org/fulltext.asp. What skills do employers want? How do these skills match those that youth and adults are developing through their school and work experiences? How can education and training programs prepare individuals to enter a rapidly changing workplace? These and other questions are examined in this Digest that explores skills currently needed for employment. Since 1986 the authors of no fewer than six ERIC Digests and one Trends and Issues Alert have sifted through an increasingly prolific literature base to investigate the evolving topic of employability skills. The dual challenges of competing in a world market and rapid technological advancements have necessitated a redesign of the workplace into an innovative work environment known as the high-performance workplace. This environment requires a behavior and orientation toward work that go beyond step-by-step task performance. It expects workers at all levels to solve problems, create ways to improve the methods they use, and engage effectively with their coworkers (Bailey 1997; Packer 1998). Knowledge workers who demonstrate this highly skilled, adaptive blend of technical and human relations ability are recognized by employers as their primary competitive edge. Job-specific technical skills in a given field are no longer sufficient as employers scramble to fill an increasing number of interdependent jobs (Askov and Gordon 1999; Murnane and Levy 1996). Many U.S. and international authors point out the importance of continuously developing skills beyond those required for a specific job, and they identify employability skills that enable individuals to prove their value to an organization as the key to job survival. The volume of major studies undertaken in the past 2 decades to identify and describe employability skills underscores their criticality. (For a listing of some of these authors, organizations, and studies, see the references.) There are many definitions of the phrase employability skills. The following updated definition is representative of a synthesis of definitions as they have evolved over time: Employability skills are transferable core skill groups that represent essential functional and enabling knowledge, skills, and attitudes required by the 21st century workplace.
