Einstein- Rosen Essay Example for Free

Einstein- Rosen EssayAccording to physicists worm holes which atomic number 18 withal referred to as bridge of Einstein- Rosen are space clip topological features that primarily puddle shortcut through time and space. A wormhole has a minimum of two communicates linked together by a unity throat. Matter travels from mouth to mouth through the connecting throat. Wormholes that are intra universe links locations universe, by simply bending the space time and by allowing travel between different locations of the universe at a faster rate than light could take in order to cover the same distance through the normal space (McElwee, Para 2). Wormhole practicable action has been proven through the use of radio waves which are capable of detecting the wormholes. The white hole theory helps to explain the wormhole theory. The white hole is opposite of the smutty hole, whereas the glum hole eats national up the white hole splits it up. The wormhole acts like a tunnel that connects the low-spirited hole to the white hole. Since the universe of discourse of black holes and white holes is proven by use of radio waves to detect them, then the wormholes also exists to link them through a tunnel (Sexton, Para 4).The wormholes are also comm and referred to as Schwarzschild wormholes they are bridges which are merely theoretical between space areas that are speculated to be in between the white holes and the black holes linking two universes. They only exists in equations especially those of Einstein. According to the equations the wormholes are found to be very unstable and would in fact fall instantly, the moment they are created. Other speculation also exists explaining that quasars are in fact white holes and not black holes which are super massive (McElwee, Para 5).It is not possible for the wormholes to exist since it is in fact impossible for a traveler to pass through the wormholes since it is not possible to pass a horizon in single direction. If non exot ic matter form the traveler, then the moment they reach at the middle of the wormhole then it is impossible to leave through the other side and over again it is not possible to leave using the entry route since the entry side must have been a black hole, this therefore, means that nothing freighter manage to escape once it has entered into the radius of the Schwarzschild.Thus the wormholes do not exist and are only a fiction feature and they can only be proven by theories with no pragmatical to prove their existence (Sexton, Para 5). Black holes are basically deformation of the continuum of space time that appears once there is an explosion of a star in the scale of supernova with its remains becoming the black holes and neutron of stars. The gravitational force pulling the black holes is very puissant and cannot tied(p) be withstood by thousands of suns masses. The white holes on the other hand are opposite to the black holes.Their work is to split matter into smaller pieces instead of eating as it is the case for the black holes (McElwee, Para 7). Theoretically the white holes are reverse to the black holes their being is implied by a solution of square root which is taken to be negative of the metric to the Schwarzschild. This metric is basically based on the time symmetry of general relativity. This implies that the scoop out definitions of white holes which can be taken to be technical are primarily black holes running in the reverse direction.This is location of space time which is not possible to reach instead of failing to escape (Kruglinski, Para 6). Conclusion The wormholes, black and white holes can only be explained theoretically even though it is possible to detect them by use of radio waves. Their existence therefore, remains theoretical as it is not supported by substantial practical evidence. But this cannot be taken to mean that they do not exist since more research work is being carried out and may be their existence might soon be reve aled practically.

JC Penney Advertising Essay Example for Free

JC Penney Advertising EssayAs time progresses, the globe, in terms of business is rather contracting. in that location is growing communication, interaction and exchange between different parts of the world. Technologies that were once thought of as a far sighted notion are without delay cosmos employ like household commodities and communication mediums that were once considered luxuries avail fitted to few are now necessities needed to prosper. And as the world is becoming much integrated and countries are becoming much than and more dependent on one another in terms of trade and business the concept of branding, ad and progress is becoming more prevalent and widespread. This paper will focus on the marketing of JC penny. It would elaborate on the print as well as online marketing. Moreover it would compare and contrast advertising of online and bricks and trench mortar companies. Discussion The demand for accountability of marketing is rising and excessively the pre ssure of having less absolute dollars to proceeding with so there is utmost need to be sharper, more purposeful and more targeted with marketing. JC Penney is a general retail brand that specializes in clothing, accessories and home furnishing.It has been rough for decades and has been catering the needs of consumers of all ages and backgrounds. JC Penneys main target audience at the present quantify is women as well as youngsters. JC Penney faced criticism for being a brand that accommodated only the high-end and older generation. However, they have been changing their brand image and have been successful in implementing an image that is portraying a more young and trendy vibe. It now focuses on providing products that have the characteristics of being conservative, traditional, modern or trendy.Fundamentally JC Penney has been escalated in the last years is through the fact that it has go from locoweed marketing to a more targeted approach. The few reasons for this change is that JC Penney believes that when business is difficult there is a lot greater chance of success with acquire the arms around the best customers and increasing frequency share of wallet and trips with the best customers then trying to recruit new-sprung(prenominal) customers in tough times that may not shopping the brand.JC Penney has managed to find ways to develop formats that allowed it to get more productivity out the money that is spend. It has also become more targeted in terms of customer selection through becoming much sharper about making sure the right customers get the right format in the right piece. (Fetterman, 2006) JC Penney is one of the brands that hold the significance of being a brick and mortar store as well as an online retailer. Hence, it follows branding through all of the sources of mass media. It publishes magazines and postcards for the promotion of its products.It also advertises it products and offers through newspapers, tv set ads and online ads. Whe n comparing the online and print media usage it quoted by Mike Boylson the Executive Vice President and Chief Marketing officeholder of JC Penney that In the postcard you can deliver more of a sales message, or more of a discount message these postcards may drive the customers online to strike the full assortment online where as the larger brand books of JC Penny show a much richer sense of the style that they have and they portray fundamentally all different messages.The postcard includes the offer and a link to the website to go see the expanded content where as the book itself that goes out shows the product, the customer can then either come in the store or they can go online or place their order on the phone. Direct mail is very important because through versioning and through customer segmentation the company is able to send out more targeted messages that are highly accountable and are also able to track the results in direct mail to a degree that cannot be possible in a lot of the other traditional mass media used by JC Penney.JC Penney has been focusing a great deal over its brand image and has been trying to diversify and broaden its target audience. It has recently changed to a new brand motif Every day matters along with the new tag line, the company has been working on enhancing its customers services and the opening of several temporary promotional stores. JC Penney is focusing on increasing the popularity of its brick and mortar stores as well as its online retailing through providing customers with latest offers, discounts and showcasing their product line online for ease of access. Sloan, 2007) As the world is advancing so are the technologies and the ease with which communication is possible among all parts of the world. With the advent of the profit and the upscale increase in its popularity, there has been well-nigh nothing that is not available on the World Wide Web. The phenomenon of e-shopping emerged with the internet. The fact that customers could get what they want in the ease of their homes, increased the recognition of the internet and also of online shopping.There are numerous differences and similarities between online shopping and traditional shopping. But what holds more importance is the way the companies market their product online and how different it is from the marketing and promotion of brick and mortar companies. (Lowrey, 2008) Marketing over the internet is considered less costly, as it is holds a lower cost of distributing information on a global platform.More and more business are moving towards online retailing due to its outnumbered advantages in terms of cost, convenience and mobility of information over a great distance. One of the major focuses that companies including JC Penney is on the website. The success of online marketing is highly dependent over the outlook, design and the information provided by the website. Both the online companies as well as brick and mortar companies need to secern their target audience before they implement any marketing strategies.This lets them focus on the type of marketing tool they would benefit them. Brick and mortar companies offer a more traditional aspect of shopping and they also follow a traditional approach of marketing. This is mostly through mass media such as newspapers, television broadcast and magazines. With the passage of time, there are less and less companies that focus solely over brick and mortar business. Most companies are now available online as there is less overheads and larger audience prone to response through the internet.Conclusion In the end it is imperative to recognize the increasing importance of internet in business. Both, online retailing and brick and mortar companies hold their own set of characteristics that make them distinct. As the progress of online shopping is increasing there is still need for brick and mortar stores for traditional shoppers. Most companies, however, imply both the alter natives and hence, carry out their marketing accordingly.

Reflective Assessment on Mathematics and Calculus

Reflective Assessment on Mathematics and CalculusReattainment the calculus, relating it to real- livingMela AzizaBackgroundI reserve loved doing maths since I was in elementary school. However, this none changed a little bit when I was at secondary school. My math teacher asked me to memorise many formulas and principles related to advanced topics without have a go at iting when I brush aside social function those in my real-life. I thought that an advanced topic was really hard to arrest because it was commonly abstract concept. Consequently, a student like me would fetch difficulties how to make it concrete and connect it to the real world. In addition, my maths teacher only encouraged us to study mathematics hard in sight to achieve high scores in examinations. She r atomic number 18ly explained about the application of mathematics in our daily life. This situation made me less enjoyed tuition mathematics. For example, maculation I was learning calculus that I assume d as an advanced topic, I did not know when I privy use it in my life so that I was not motivated to learn it. At the term, I guessed calculus was useless. Calculus was just about rules, formulas, and calculations without knowing why I admitd to learn it. Therefore, this experience has been inspiring me in how I should teach my students in the future.I hoped to explain and show my students about how powerful and useful mathematics can be. Unfortunately, it was really hard to invent the connection between mathematics and daily activities, especially for the calculus. My students were questioning when they could use calculus in their life. I became confused and could not give the appropriate answer because I have not known the application of calculus that was relevant to my students life. I taught calculus exploitation the similar manner to my previous mathematics teacher, solving any kind of calculus questions from my own textbooks using the formulas or rules. However, I am interested in exploring and developing the public-service corporation of calculus in daily life because I want to raise answers for my own previous question, when I can use it. Hence, when getting the chance to add the developing subject knowledge course, I was excited to focus on or so calculus questions using real-life contexts.Solving calculus worrysI started my independent learning by solving the max box problem given by my personal tutor (see Appendix A). This problem about the paper which has side a, consequently I was instructed to make a box by cutting a square with side x from each of the four corners. I have to puzzle the value of x so that I can make the biggest box. I tried to find the x value for creating the biggest box by doing some algebraic equations and finally, I obtained the pattern for finding the x value. Finding out the answer gave me an opportunity to relate it to the concept of differentiation. It was a new thing for me and when I searched on the int ernet, found it was popular in teaching and learning mathematics related to the calculus topic. However, I did not know why I found Indonesian mathematics teachers rarely used this practical question while teaching the concept of differentiation.Next, I moved to how to introduce the first principle of differentiation, f(x), from expire f(x). I started by drawing a graph of the bureau, then formulated gradient of devil adjacent points using the gradient of a straight line and sterilise concept (see Appendix B). Finally, I found that the first differential coefficient equals with the gradients of a point from the affaire. Then, I tried similar calculations for some different functions, and finally, I complete the pattern of the first derivative. While doing this, I was thinking which I should teach first, gradient or differentiation, in effect to make students understand where the first derivative comes. Furthermore, a noticeable point for me by solving this problem, I was aw are that as a teacher I can teach mathematics through using algorithmic/algebraic/analytic/calculating, visual (image/graph), and inductive (pattern) thinking. For example, when finding the maximum value of the function, I acquired the same answer by using cardinal different methods, graphing and calculating.In addition, I explored how to draw the graph of the first derivatives of different functions by using gradient concept (see Appendix C). I drew both common and uncommon functions. I felt those were interesting and challenging because I could create the graph of the first and the second derivative just by face at the graph of the original function. However, when I want to find the first derivative function, I have to calculate using an algebraic method. Although I could not get directly what the function of the first derivative f(x) through drawing, I could differentiate when the function reached maximum value, (when f (x) f (x) 0), and neither maximum nor nominal value (wh en f (x) = 0), for instance, f(x)= x3-6x2+12x-5 having an inflexion point (see Figure 1).I also tried to find the gradient of uncommon functions such(prenominal) as an absolute function (f(x)=x) by plotting the graph manually and checking it using software GSP (The Geometers Sketchpad), then I found that there was a point on the xfunction that cannot be differentiated (non-differentiable point) that was when x = 0, but for different points, those were differentiable (see Figure 2).Furthermore, I explored six common mistakes (Cipra, 2013) that students made in doing calculus related to how they answer some routine problems and understand a concept of finding the area of function by integral concept (see Appendix D). The students mostly just calculated the area using formula without drawing the function so that occasionally they found a detrimental area. The area entrust be never negative. The students should know that the area above x-axis will be positive because y-axis values are always positive while the area below x-axis will be negative because of y-axis negative values (Stewart, 2016). Hence, students have to multiply the area of function below x-axis with negative (-) in favour of becoming a positive area.ReflectionDuring this course, I relearned calculus concept by solving some problems. I felt back a find of doing mathematics when solving the problems both routine and real-life problems. This sense made me excited to find the solutions for any problem that I faced. I became aware that abstract concepts cannot be separated from calculus. Although routine problems are commonly abstract, students will be able to learn the importance of symbol concepts in calculus through solving these problems. I also tried to connect calculus by solving some real-life problems which use real-life contexts and can be reckond as daily experiences (Gravemeijer Doorman, 1999), for instance, the max box problem that can be connected to a manufacturer. aft(prenominal ) doing some real-life problems, I agree that these problems should be taught in the schoolroom (Gainsburg, 2008). Teachers are able to use these problems to enhance students motivation and to develop reasoning as advantageously as problem-solving skills of students in learning mathematics (Karako Alacac, 2015). Therefore, the teachers will be able to make mathematics become more meaningful for their students through real-life problems.On the other hand, I think not all real-life problems are practicable for students because the problems do not relate to their life directly. I have done some problems from some websites and a textbook of calculus (SMP, 1973), but not all problems were relevant to a real context and could be solved. I encountered there was a problem when some facts are lay offed in order to make students understand the question easily. A problem which is relevant to one students life may not be relevant for others. Therefore, teachers should check the effectivenes s of the problems by asking students first (Burkhardt, 1981), and then they will notice the good problems that can be used in the future. In addition, calculus is advanced knowledge for most students because they find it difficult to concretise so that occasionally it should remain abstract (Wilensky, 1991). Furthermore, teachers need to consider the time when they give the students real-life problems. They cannot give them these problems for every meeting because they also should provide opportunities to students for learning all calculus concepts, both concrete and abstract. Thus, most teachers assumed the nature of mathematics topic and the time may become limitations for connecting it to the real-world (Karako Alacac, 2015).Teachers can motivate students to think inductively in learning mathematics. They may involve students to find the first derivative pattern by using the gradient of a straight line and limit concept. They should not give a pattern f(xn) =nxn-1 directly to st udents when introducing differentiation, but they ask students to establish the first derivative pattern by their own self. In addition, I found that teachers are able to use a slope of zero (f(x)=0) for tally out what is the maximum or minimum value of the function quickly. However, teachers also have to ask students to check the graph or the second derivative of the function to find the exact category of the x value (maximum, minimum, or inflexion point). Hence, as a mathematics teacher, I should deem some factors before decision making an effective teaching method that encourages my students to understand calculus concepts easily.I assumed that using technology can make sense of calculus for students. I considered using GSP while teaching to draw a graph of the function and to look closer whether the function can be differentiated for every point. Furthermore, I think that mathematics teachers may be able to explore any kind of calculus questions on websites such ashttps//www.m ath.ucdavis.edu andhttp//www.dqime.uni-dortmund.de which I assert as resources for finding real-life mathematics problems using the English language. However, teachers who come from non-native-English-speaking countries should be careful in understanding the meaning of the problems because there was a specific English term of mathematics that sounds foreign or synonymous. For instance, I was confused to distinguish between two words that felt to be synonyms like capacity and volume. I firstly thought that those two words had similar meaning, however, capacity related to how much liquid held while volume related to how many materials needed (solid) in the container. Teachers also may correct examples of the calculus projects and the application of calculus videos that are provided on the internet. Personally, I obtained the new perspective by watch some videos showing activities that teachers did like creating a classify project related to the application of calculus. However, te achers should consider about the time because doing a project or watching a video will be time-consuming.Teachers require looking at why students made the mistakes and analysed what they should do to prevent similar mistakes among students. Students solve calculus problems using algorithms involving symbol concepts but they commonly forget to crosscheck the use of the symbol in their works. As a result, they made mistakes in using symbols which are shown in Appendix D. Furthermore, visual thinking is an important skill to abandon mistakes in finding solutions for calculus problems especially to find the area of the function. It happened because they did not draw the graph of the function. Meanwhile, students only will be able to identify the perplex of the graph either above or below the x-axis when they look the graph directly. Hence, teachers should be more aware that algebraic, symbol, and drawing the graph or visualisation are crucial concepts in learning calculus.Implementatio n in IndonesiaOne of the reasons why I wanted to explore the usefulness of mathematics and how to teach it in the classroom is the aim of teaching mathematics in Indonesia. Indonesia has adopted RME (Realistic Mathematics Education) from the Netherlands, and then known as PMRI (Pendidikan Matematika Realistik Indonesia) which correlates to teaching mathematics in real contexts and emphasises the application of mathematics (Sembiring, 2008). However, RME does not mean teachers have to involve the students in real activities but create a meaningful learning activity so that students can imagine it like they do reality (Van den Drijvers, 2014). Even though some previous researchers found that the implementation of PMRI in Indonesia had positive effects on students mathematics achievement (Armanto, 2002 Fauzan, 2002), Indonesia has not made relevant PMRI curriculum materials (Sembiring, 2008). Therefore, Indonesia still needs to develop some resources related to the implementation of P MRI.In addition, Indonesian mathematics teachers aptitude itself will be a difficulty in implementing teaching mathematics in real contexts. Although one of their concerns is connecting mathematics to the real world in order to encourage students to deal with their daily life problems (Zamroni, 2000), some of them are only able to teach instrumental understanding (Skemp, 1976) in the classroom so that students learn calculus as formulas without realising how they use it. Students just follow teachers instruction memorising formulas, understanding the examples, and then solving the exercises. Undeniably, students own negative perspectives on mathematics, including the calculus, are due to this fact. Thus, teachers should find ways to improve these students perspectives in order to enhance their understanding and achievement in mathematics.Mathematics teachers can develop realistically applied mathematics in the classroom through the collection of realistic problems (Burkhardt, 1981) that provide an opportunity for students to apply their mathematical skills. Personally, there are some real-life problems that Indonesian teachers can use such as Max box. I am curious what will happen when I and other teachers use this problem before introducing calculus to the students, maybe, we will fill in kinds of methods from the students that we have never imagined before. Furthermore, Indonesian mathematics teachers should explore resources on the internet and use software like GSP in order to stimulate students sense of learning calculus. However, they may encounter further difficulty in using GSP or e-based learning method because not all of them can operate it and not every school has technological equipment as well as internet connection. Another point that Indonesian mathematics teachers should deem is students common mistakes in learning calculus. Teachers should be aware that students have to check their own work to find the mistakes because if they check by thems elves, they likely will not repeat the same mistake. Teachers also have to check their students mistakes to analyse the reasons, then reviewing and correcting the misconceptions that student have from the mistakes.ConclusionDespite the fact that it is common that students feel calculus is difficult to be understood, solved and applied, I think there will be some solutions that teachers can do such as giving both realistic and unrealistic problems, using software, and watching application of calculus on videos. Besides these ways being likely to motivate and encourage students to learn calculus, these ways also can stimulate students using it in their real-life. However, teachers have to consider the practical problems for students and keep giving some routine problems to look closer what some misconceptions or mistakes that they made in doing calculus.

Learning Outcome Peg Feeding Nursing Essay

Learning Outcome Peg Feeding Nursing EssayIn this contemplative essay I am going to discuss a acquirement outcome in which I bind become competent to practice. To reflect on my learning outcome I am going to use up Gibbs reflective model (1988). The Gibbs reflective model is a well known and used model in reflective practice. It consists six steps which I go away describe step by step as my essay will progress. In the nursing care process it is a responsibility of a defy to provide holistic care to the patient who is under our care. Our focus is to en suitable them to cope, pr character, solve or alleviate the problem from which they are suffering and not able to carry out their normal life. Our aim is to help and teach patients how to meet their daily needs in other ways. The learning outcome I have chosen to reflect is ramification feeding which is an alternative way to provide nutrition to a patient who is not able to obtain nutrition finished the mouth.The first step of Gi bbs reflective cycle is a description of the event. One service user in my placement area whom I will holler Mrs. P to admit her confidentiality (NMC 2008) is suffering from progressive supranuclear palsy, a condition in which as the condition progresses patient losses abilities i.e. Swallowing, speech, maintaining balance, eye movement. As a conduce of this condition she developed dysphagia and it was not possible to maintain her nutrition via oral intake. Thus, multidisciplinary team and family decided to place her on PEG feeding. PEG tube is more appropriate than nasogastric tube for long term feeding as it ward offs delays in feeding and discomfort associated with displacement (National Collaborating Centre for Acute Care 2006). During my placement unitary of the nurses asks me to go and give her water through the PEG tube. Although I did it onward in my country I was familiar with it but I didnt practice for a long time and as I have seen the condition of Mrs. P. I wasnt confident to carry out the task. I discussed it with my teach and we decide that I scum bag take it as a learning outcome during my training to make myself competent with PEG feeding skill.As I am going into the mo stage of Gibbs reflective model (1988) in which I will discuss about my thoughts and feelings. When the nurse asked me to give the water via PEG tube, at first I was feeling myself stupid to ask for help thinking that what impression I will make on that nurse. This feeling came into my mind as a vector sum of a thought that I am a registered nurse in my country so I should know this. But I lost my dominance when I went in Mrs.Ps room and observed her condition i.e. Slurring speech, problem with balance, mobility problem and pain in her neck. So I decide to ask the nurse to answer the task and I in addition observed it. While she was giving her feed, I found that she was coughing a lot and wasnt comfortable. Which I thought was due to her sic and the nurse explain ed me and justify my thought that it is because of her condition. I was not satisfied with her explanations and as a supervised practice nurse I wasnt able to oppose her. I decide to read more about the PEG feeding and discussed it with my mentor.The third stage of the Gibbs model (1988) of reflection is an evaluation which requires the practitioner to consider the life-threatening and pretty things about the event. The patient should be conditioned where the patient can sit up as much as possible in a supported midline position (Dougherty and lister 2008) while giving PEG feeding. The nurse who gave feeding didnt correct Mrs. Ps position as she was in a semi practiced position. Furthermore, before starting and at the end of the feeding, she didnt clean the tip of the tube. The tip of the tube should be cleaned daily with water and a small brush (Loser et al.2005). However, the good practice I observed that nurse informed the procedure to Mrs. P which is important according to the NMC (2008) to make her understand the procedure and give her consent. In addition, to annul tube adhering to the stoma skin rotate it 360 degree (Bumpers et al, 2003). The other important thing my mentor discussed with me was administration of medication through the PEG tube. According to BAPEN (2003a), neer add medication directly to the eternal feed to avoid interaction between medicine and feed and flush the tube after administration to avoid tube blockage. During the discussion about PEG feeding with my mentor I found that other things to consider with PEG feedings are management of the tube, patient position and checks to carry out before feed and it is very important to avoid complications. In my placement area only Mrs. P has got PEG tube. So my mentor discussed with me that there are many indications for PEG tube insertion according to the patients conditions so it is important to learn about the specific needs of that patient before performing the procedure. She discu ssed some scenario cases with me to understand more about it. This helped me to understand different aspects of the PEG tubeThe next stage of the Gibbs reflective cycle (1988) is an analysis of the event where reflector has to make sense of the event. I will analyze it by exploring the skill and looking into the evidence. The PEG feeding is a method of giving nutrients to maintain an optimal nutritional support (National Collaborating Centre for Acute Care 2006). Clinical trials have proven that there are very rare complications with PEG tubes, such as leakage (Riera et al. 2002). Through evaluation of this event I have been competent to give PEG feeding and care of the tube. The reasons for Mrs. Ps coughing explained by the nurse was from her daily ascertain working with her which could be right but what I found from the references was different and evidence based. So I learned from experience and through experience (Burnard 2002). It has boosted my confidence to challenge others views regarding my practice.According to stage five of Gibbs model (1988), I conclude from that every nurse does not find the alike evidence based reasons for the problem but if I am practicing safe and based on evidence then my practice is safe. In the future I will make sure that I am confident and competent to perform the task and have evidence based explanation of the situations. From this particular learning outcome I have learned about a PEG feeding procedure and the care of the PEG tubeThe last stage of Gibbs reflective model (1988) is the action plan. My action plan for the future practice is to read more references and literatures regarding PEG feeding. There will be many different conditions regarding PEG tube in my future practice so it is necessary for me to look for more information on this particular subject to make myself excel. I also request my mentor to book me for a study day to learn more about this skill.

Nuclear Power Advantages and Disadvantages

thermo atomic Power Advantages and DisadvantagesThe title question of my case study is Should thermo atomic Power be Banned. I gestate chosen this question as I mean it is a key topic at this present fleck in life, with a confirm by of information about it in the media, much(prenominal) as on the news and in the papers each day. Also it is almostthing that lead affect the life in which we live in the future. So beca substance abuse of these fences it is something that wad need to be aw be of and need to actu eachy understand what thermo thermo thermonuclear top executive is and how it is affecting us or is going to affect us in the years to come.Evidence forOne major problem that could occur with nuclear function is that in that location is always the risk that on that point could be a escape of hot fluids, which will have a massive impact on the milieu and its surroundings. These radioactive fluids that may leak from the forcefulness stations fuel spring back sidecers and in truth harmful illnesses in humans. So for this reason people will believe that yes, nuclear power should be banned, especi tout ensembley those people living around or near a nuclear power station, or those that have clam up relatives that may be bear upon if something alike(p) this were to happen.-I hold that this is a reliable piece of information as it is a very valid reason, and plunder be found elsewhere on the internet, on various early(a) directs which proves to us that separate people atomic number 18 in addition victimisation this information as licence for their arguments, so we should as well.Evidence againstA reason against banning Nuclear power is that it provides a flowerpot of our energy solutions, and can be used to bear electricity and to power ships, so therefore we need nuclear power to continue doing these things, and if we were to get exempt of it then we would only have to resort to purpose an another(prenominal) way of provid ing this energy, which is only going to cost even more money, on top of what wed already be paying to get rid of the nuclear power plants that exist at this moment in time.. Without the use of the ships that are powered by the nuclear power, we would have a lot of problem in transporting goods such as food and material from one charge to another.(http//uk.answers.yahoo.com/question/index?qid=20090121112744AAxRJTv)25th September 2010, 1030. I think that this is a genuinely reliable source of information in the respect that it is a reasonable argument for why we shouldnt ban nuclear power. Although this may in any case be enchantn as not so reliable as it is written by a member of the public, someone that may not have a lot of knowledge on the topic, but has heard bits about it. Besides that fact, I agree with this argument against banning nuclear power so therefore am going to use it as evidence in my case study.SCIENCE BEHIND NUCLEAR POWERNuclear power is made and generated by u sing uranium. Uranium is a metal that is mined in various different parts of the world. Most on worlds Uranium is mined from Australia, Canada and Kazakhstan.The first ever large nuclear power station was opened in 1956, in England in the city of Cumbria at a place c aloneed Calder H whole.There are a do of military ships and submarines that contain nuclear power plants as their engines in read for them to keep up and running.Nuclear power produces approximately 11% of the worlds energy source and can produce very large amounts of energy from only a small amount of fuel. As well as this there isnt all the befoulment along with it like there is when you burn fossil fuels.(This can therefore be seen as an argument against banning nuclear power plants as there is the intense of fossil fuels that is taking place which are producing greater amounts of pollution than what nuclear power stations are giving off.)The equation above shows us what happens in a nuclear power plant and the stages in which it goes through before it reaches our homes and provides us with the energy sources that we use in everyday life.It is in the Nuclear fission where the Uranium is used, this starts off the process for nuclear power to be generated. Nuclear fission is the process of atoms splitting, so when a heavy nucleus such as Uranium splits into two smaller, lighter nuclei. In this reaction, the strong nuclear force which is the attractive force, is acting on the electrostatic force which is the repulsive force, these can be knocked out of balance on each other when they gain the energy from either a photon or a neutron. The two forces are affected by the gain of this other element and will try to act on each other to regain the state in which they were in, but in nuclear fission the electrostatic force will gain more power than the nuclear force, therefore causing it to repel and for the nucleus to split apart, also releasing energy as it does so.To make this slightly easier to understand, imagine a load of marbles in a rough circle shape on a flat tabletop (this is going to be representing the original atoms nucleus, where all the forcing are acting the same on one another and are equal, so all the marbles/atoms are stable). What if I were to then throw or roll another marble into this group of stable marbles? All the marbles would dust apart and move out into the space around them, this marble that is macrocosm rolled into them is acting as the photon or neutron that is being gained in the nucleus. This is unbalancing the forces and causing the atoms to all move around as they react to the change that is taking place, but seeing as all the marbles move out, and away from each other shows to us that the repelling force has gained more control, as the attractive force wasnt able to keep them all together, and this is exactly what happens in nuclear fission.(http//library.thinkquest.org/17940/texts/fission/fission.html)(http//physics.about.com/od/glossar y/g/nuclearfission.htm)Both of the sites above were visited on the 30th January 2011, 1515.-I think that both of these sites are reliable sites to use as evidence in my case study, and one of them is a site specifically focusing on physics topics and gives very scientific definitions to certain topics involved in physics. Also the other site is made by university students, that did a study on nuclear fission and how it takes place, they then put all their information together on this site for other students to look at and use if they need the information required. I have combined the information from both websites to give an overall example of how nuclear fission takes place and what it involves.Nuclear power that is made by Uranium is not renewable, this means that once we have dug up the Earths supply of Uranium there will be no other way of getting any more, so once its gone its gone.There are several advantages and disadvantages to nuclear power these includeNuclear power costs roughly the same amount as coal, so in that respect its not too expensive, so this is an advantage.Although, millions of pound has to be spent each year to supply the safety that is required in a power plant, this is because if they were to take the chance and something went wrong like a nuclear accident, then this would result in a major disaster.The making of nuclear power does not give off a plenty or carbon dioxide, so therefore we can be sure that this is not contributing to the greenhouse effect that is causing global warming, unlike the burning of fossil fuels which do contribute to this, so this then puts nuclear power at an advantage.Also, as mentioned previously, huge amounts of energy can be made by just a small amount of fuel. With only small amounts of waste being produced, once again putting nuclear power at an advantage. proverb that, although there isnt much waste being produced, that that is produced is extremely dangerous and would have to be stored, sealed up and buried for thousands of years to allow the radioactivity to cease away. During this time it has to be kept far away from any potential natural disasters such as Earthquakes, Volcanic eruptions, flooding and terrorist attacks. This can be very difficult at times.Another disadvantage is that in the 1990s was the fastest growing source of power in most of the world. However, in 2005 this then deteriorated to being the second slowest growing source of power throughout the world.(http//www.darvill.clara.net/altenerg/nuclear.htm)30thJanuary 2011, 1700.-This is a website purely based of evidence for and against nuclear power, and its advantages and disadvantages, it has lots of information unaccompanied on nuclear power, which makes it a reliable source of evidence to be used.There are many different reasons and opinions to why people think nuclear power should be banned, some of which are due to things that have happened previously, and if were to happen again could cause a massive upr oar throughout the world. Others are what people are scared could happen, and because of this they believe that nuclear power should be banned.Here are some examples of previous accidents that have happened involving nuclear power, which could be a reason influencing peoples decisions on whether or not this should be bannedMarch 28, 1979Near Harrisburg, Pennsylvania, Americas worst nuclear accident occurred. A partial meltdown of one of the reactors constrained the evacuation of the residents after radioactive splatter escaped into the atmosphere.The radioactive gas that got released into the atmosphere is a cause to cancer in the human body, and as we all know, cancer kills very easily It may take 20 years or so, for the residents to even realise that they have cancer, as it takes time to affect and the gas in the atmosphere lingers for years.April 26, 1986The worlds worst nuclear accident occurred after an explosion and fire at the Chernobyl nuclear power plant. It released radi ation over much of Europe. thirty-one people died in the immediate aftermath of the explosion. Hundreds of thousands of residents were moved from the area and a similar number are believed to have suffered from the effects of radiation exposure.As you can see already from this 31 innocent people died from a nuclear power accident, thats hundreds of people left without a family member, and what if this was to happen again, but this time it could be even worse, and possibly even more people killed. Also from this event, thousands and thousands of people were once again exposed to the radiation which can cause cancerous cells in our bodies, which could lead to a number of deaths years down the line, all from this one accident that happened because of nuclear power.(http//www.atomicarchive.com/Reports/Japan/Accidents.shtml)25th September 2010, 1930.-This website is a university website, which is very factual and all its points appear to be logical and authoritative, also the fact that its scientists writing the points and information only gives us more reason to believe its true and reliable.Many risks are taken when using nuclear power, there is always the risk of a meltdown occurring, or even a leakage of radioactive waste. There is also a risk to the workers safety and well-being as storing waste from nuclear reactors can be a problem in some cases. A nuclear meltdown is when the cooling systems fail, and the nuclear reactors reach such a temperature that they melt straight through the reactor or damage the reactor wall. With this melting, then allows the spread of radioactivity, which as before can cause great damage in the human body. There is also the chance of contamination at bottom the environment if there was to be a leakage of radioactive waste in that area. Radioactive waste, if gotten into the workers at a nuclear power plant, can also poison them, which furthermore, would take their life.On the other hand, there are also many reasons as to why peo ple believe that nuclear power shouldnt be banned, some of which are listed belowNuclear power generation does emit relatively low amounts of carbon dioxide (CO2). The emissions of green house gases and therefore the contribution of nuclear power plants to global warming is therefore relatively little.This technology is readily available it does not have to be developed first.It is possible to generate a high amount of electrical energy in one single plant.(http//timeforchange.org/pros-and-cons-of-nuclear-power-and-sustainability)28th October 2010, 1735.-I think that this is a reliable website to get information from as it is based on the pros and cons of nuclear power, and what needs to be done to make a change, and what needs to stay the same. It cannot be edited or changed by anyone other than the creators, and the creators are have done a lot of research to make the website to the high standard of what it is now.In 2005, approximately 6.3% of the earths energy supply relied on n uclear power, and gradually over the years, this has increased slightly to 14% in 2009. It also provided 15% of the worlds electricity in 2005 and again in 2009. If we were to ban nuclear power then there would have to be other ways in which this supply of electricity was formed, and therefore more money is going to have to be spent out in order for this supply of electricity.As you can see from the statements above, it clearly states that nuclear power can generate a lot of electrical energy in just one single plant, and with there being 440 plants across the world this would cost an awful lot of money to get rid of and then replace the energy and electricity in which it supplies us with.Nuclear power also provides for ships and submarines, which we need to transport food and goods from country to country, without these ships we would have to find another way of transporting the items, say if we were to use a plane for example, then this would only be adding to global warming which is another issue know world-wide.(http//www.world-nuclear.org/info/inf01.html)27th September 2010, 1835.-I believe this graph to be a reliable source of evidence as it is from a website specifically center on the use of nuclear power all over the world, in various different countries. Also it is not biased in any way, and it wholly based on facts and figures rather than opinions, so therefore this is a reliable piece of information to be used in this case study.As you can see from the graph above, most of the large MEDC (More Economically Developed) countries reply on nuclear power as a source of energy and electricity. Although there are other ways of them getting their energy supply, with the loss of nuclear power, they would only have to increase one or more of their other supplies in order to make up for what they have lost from the lack of nuclear power.SHOULD NUCLEAR POWER BE BANNED?Taking into account both sides of the argument, we can see that there are many reasons for n uclear power being banned, just as well as reasons for nuclear power to not be banned. The primary(prenominal) reason that people believe nuclear power should be banned is that there is always the risk of a spillage of nuclear gases, or a leak in the power stations, which would have a great impact on humans health. The main reason as too why nuclear power shouldnt be banned is that it provides a huge amount of the worlds energy and electricity source.As you can see from the for and against arguments on the previous pages, I think that overall the benefit of nuclear power outweighs the risk so therefore nuclear power SHOULDNT be banned, and I think this becauseto get rid of all the nuclear power stations over the world would cost an awful lot of money for the governments and thats money that could be put to a better use elsewhere. Also after paying out to get rid of the nuclear power plants throughout the earth, we would then also have to pay for other methods of providing the elect ricity and energy resources that these plants provided, it would be easier and more efficient to just spend the money into finding more ways in which we can prevent a leakage at a power plant and how we would handle such a situation, if another one were to occur. Nuclear power plays too big a percentage in everyday life, we just take it for granted and dont actually realise how much we do rely on it.Furthermore, as for the number of deaths that have occurred from nuclear power accidents there are so many things nowadays that could kill people, we just try not to look at them in that way, for instance there could be a massive pile-up on a motorway and kill a numerous amount of drivers, passengers and general citizens, but that doesnt mean that people are going to stop driving does it? So why should nuclear power be banned because of the risk of there being a fault that could cause deaths among humans? The workers in nuclear power plants, are fully aware of the risks they take every day and the risks of the radiation, but safety measures are in place to protect these workers from getting harmed, and they are trained of what to do in the case of emergency, so therefore its entirely down to them to do the job or not, at no point are they being forced to work under such conditions that are putting themselves at risk.

Neurobiology of Aging and the Diagnosis of Generalized Degenerative Dis

The neurological deficits of aging may be viewed from a organic evolutional perspective. That is, the decline in functional efficiency and deterioration of highly narrow down non-dividing neuronal cells is the mop up point of a maturation process that occurs throughout adult life. Involution to senescence is a normal, inevitable, and inexorable physiological march the end phase of which is expressed in generally predictable and specifically unpredictable ways. The earliest of these developmental changes occurs long before senescence and the effects of these physiological events quiet accumulate toward expression late in life. There is a relationship between chronological age and the developmental dimensions of human life, including behavior and intelligence. This relationship begins at conception, and is at that point the only moment when in that location is exact correspondence between chronology and development. Afterwards, behavior or structural differentiation have shifting persona points one with some structural differentiation or performance milestone already achieved, the other with the time chronology (age) of the organism. Development refers to a continuum of lifelong biological and psychological processes. Neurological development along the biological scale is swift and complex during the prenatal period and small units of time constitute considerable change. In infancy, there is less neurological change as compared to prenatal development, but it is considerably more than those changes that occur in adult life. Indeed, in adult life, neurological development largely constitutes a diminution in function. Nonetheless, until the onset of senescence, in the absence of organic brain pathology, psychological development and learning co... ...otein and the neurofibrillary pathology of Alzheimers disease.

The Fellowship of Christian Athletes :: Expository Essays

The Fellowship of Christian Athletes Back in my high school, one day pop of the month was dedicated to student-led clubs. On these so-called club days, most kids will go to any club just to get out of class. Some sole(a) clubs, such as the Chess club, would look down on this. These groups would happily kick some kids, but there was one club happy to listen everyone who came the Fellowship of Christian Athletes. The little exposure to Christianity found at this club was all that some kids would get and the moderators of my schools club knew this. Little by little, this is FCAs nation-wide goal to change the world into knowing Jesus Christ. This non-profit organization is responsible for everything from small club meetings in middle schools, high schools, and colleges, to massive summer camps. The Fellowship of Christian Athletess website lists the groups mission which is to present the challenge and adventure of receiving Jesus Christ as Savior and Lord, serving Him in their relationships and in the fellowship of the church to athletes and coaches and all whom they influence (FCA). No matter whether on the court or in a group-led bible study, FCA focuses on this mission. FCAs home website is www.fca.org. This site is very well done and contains an abundance of information, such as the organizations values Our relationships will demonstrate steadfast consignment to Jesus Christ and His Word through integrity, serving, teamwork and excellence. FCAs goal of Integrity states that we will demonstrate Christ-like wholeness, privately, and publicly. For the goal of serving, we will model Jesus example of serving. As for Teamwork, we will hold our unity in Christ in all our relationships. Lastly, for excellence we will honor and glorify God in all we do (FCA). FCAs aggressive style of doctrine is pretty effective. Since 1954, the Fellowship of Christian Athletes has been challenging coaches and athletes on the professional, coll ege, high school, junior high and youth levels to use the powerful medium of sportswoman to impact the world for Jesus Christ. FCA is the largest interdenominational, school-based, Christian sports organization in America. FCA focuses on serving local communities by equipping, empowering and encouraging people to make a going for Christ.
