Nucleosynthesis essays

Nucleosynthesis essays The "big bang" which created the universe, only created the elements Hydrogen (H) and Helium (He) and possibly a very small amount of Lithium (Li). However, a glance at the periodic table of the elements shows that today (some 15 billion years after the big bang) there are at least 108 known elements. Every atom of every element heavier than Li has been produced since the big bang! The "factories" which make these elements are stars. "Nucleosynthesis" or the synthesis of nuclei, is the process by which stars (which start out consisting mostly of H and He) produce all other elements. The key is nuclear fusion, in which small nuclei are joined together to form a larger nucleus. (This contrasts with nuclear fission, in which a large nucleus breaks apart to form two smaller nuclei). Fusion requires an extremely large amount of energy (see fig. 1), and can typically only take place in the centers of stars. a) Low energy proton is strongly repelled by the 7Be nucleus.b) High energy proton moves so fast that it can strike the 7Be nucleus. Once the proton touches the nucleus, it has a chance to stick. If the proton sticks, the 7Be becomes a 8B nucleus.c) 8B is radioactive and changes into 8Be plus a positron (b+) and a neutrino (n). 8Be is itself radioactive, and almost immediately breaks into two 4He nuclei. Protons repel each other. This repulsion becomes stronger as the protons get closer together (just like when you try to stick two magnets together north to north, or south to south. Try this! As you push the magnets closer together, it becomes harder to do). However, if the protons can actually touch each other, they have a chance to stick together! This is because of the "strong nuclear force" which attracts nucleons (protons or neutrons) together, and is much stronger (at close range) than the "electromagnetic force" repulsion that makes protons repel other protons. (Magnets do not do this: two like poles wi...

The Future of Your Job Search Findings of Career Jam 2018

The Future of Your Job Search Findings of Career Jam 2018 What is Career Jam? Every year, I look forward to the Career Industry Trends released by the Career Thought Leaders Consortium. This week, the long-anticipated Findings of 2018 Career Jam: Where Experts Forecast the New the Next, was released! This report summarizes the findings of brainstorming sessions held on November 30, 2018 in the United States, Canada, Spain, Austria, and the United Kingdom. 2018 Career Jam participants brainstormed â€Å"best practices, innovations, trends, new programs, new processes, and other observations that are currently impacting or projected to impact, global employment, job search, and career management.† The sections that historically have most interested me in the report are â€Å"Career Marketing Messages Documents† and â€Å"Social Media Profiles†¦Ã¢â‚¬  which include resumes, cover letters, and LinkedIn profiles, as well as other career marketing communications. This year, the report is significantly shorter and more compact. The sections that most relate to resumes and LinkedIn profiles are â€Å"Artificial Intelligence (AI), Machine Learning Other Technology,† â€Å"Social Branding Sourcing,† and â€Å"Storytelling.† Here’s what the brainstormers have to say in these realms: Artificial Intelligence (AI), Machine Learning Other Technology Job seekers are becoming more aware of the role of technology in the hiring process. Everyone knows about ATS (Applicant Tracking Software) systems now, and they want keyword-optimized resumes. It’s likely that more platforms will emerge for job seekers to test keywords in resumes. One size resume does not fit all! Resumes must be adjusted for each application to improve keyword density and alignment to the specific target position. Issues of privacy and bias have arisen with the use of AI. These are starting to be addressed. Social Branding Sourcing Young professionals are ditching the resume! I don’t completely believe this, but certainly younger job seekers are making inroads toward applying to jobs solely through social media. In most cases, however, resumes are still requested. LinkedIn is King. Creating a strong presence on LinkedIn will increase your visibility and give you a leg up on the competition. The power of the platform simply can’t be ignored – even by older job seekers, who are increasingly embracing LinkedIn. I’m happy to report that the 14th  edition of How to Write a KILLER LinkedIn Profile is through the final editing stage and contains more robust information than ever on maximizing the power of LinkedIn! Watch out for announcements coming soon! LinkedIn keeps changing. What a headache! Thankfully, my new book addresses all the changes. LinkedIn is a prime place to nurture connections and network with alumni. Students especially are finding value in using alumni networks on LinkedIn. Not sure how to connect with alumni on LinkedIn? See my article, LinkedIn inMail Templates: Contacting Graduates of Your Alma Mater and check out the updated information in the 14th edition of KILLER! Facebook and Instagram are used by recruiters, but this is not resonating with job seekers in the US. Posts and interactions on social media are more important than ever. Computerized programs are scoring personality traits based on your activity on social media. So stay engaged in productive ways with relevant online content – especially on LinkedIn, where your search ranking is affected by your engagement [I added that last part]. Instagram is a good place to create a portfolio. Twitter is a good place to connect with influencers like journalists. Storytelling Online portfolios and personal websites are making a comeback. How interesting! Just yesterday, my self-publishing advisor was telling me he is creating a platform for job-seekers to post their resume to a personal website. Perhaps he’s caught a trend! Certainly, a website and online portfolio provide flexibility that a site like LinkedIn probably never will. By the same token, hard-copy portfolios will make you stand out and provide great interview material. Give the employer certificates, recommendations/testimonials, your most up-to-date resume, success stories, case studies, photos of projects, and other items that demonstrate your value, qualifications, and achievements. It’s more important than ever to communicate your story succinctly in your written documents. Attention spans aren’t getting any longer! So grab attention fast with a clear message. And remember, you need to engage humans while also keeping keywords in mind for the ATS systems. On the other hand, there’s a move away from the â€Å"elevator pitch.† People want to hear stories and to build relationships. Effective in-person networking is about more than a quick pitch. Be ready with stories for your interviews. Have an â€Å"arsenal† ready so you can pull the right one out of your hat. If you’ve done the right prep for your resume, these stories should be at your fingertips! â€Å"Grit† is prized. Grit and resilience are being valued more and more, so demonstrate yours! In Silicon Valley? Use slides. 10-slide â€Å"walking decks† are being used in place of resumes to provide a creative, holistic view of the candidate. Graphic design skills are required. Executive bios are subbing in for resumes for executives who are conducting a job search while employed. If you need a top-notch executive bio, please visit my Executive Bio Services page. To find out more trends, such as how age is being treated in the job market, the state of the gig economy, and how college degrees are being valued (or not), see the full white paper.

Resistant Hypertension and the Role of Renal Denervation Research Paper

Resistant Hypertension and the Role of Renal Denervation - Research Paper Example Hypertension is a common problem worldwide and is one of the major causes of mortality and morbidity. It is associated with several complications like cardiovascular disease, stroke, retinopathy, and renal dysfunction. Elevated blood pressure which has been uncontrolled for a prolonged duration of time can lead to many changes in the structure, blood vessels and the conducting system of the heart. These changes can lead to the development of various conditions of the heart such as coronary artery disease, left ventricular hypertrophy, cardiac arrhythmias, and congestive heart failure. The pathophysiology of hypertensive heart disease is a complex interplay of various structural, neuroendocrine, hemodynamic, molecular and cellular factors (Riaz, 2007). These factors not only have a role in the development of hypertensive heart disease, they also are modulated by elevated blood pressure (Riaz, 2007). Persistent elevation of BP has adverse effects on the cardiac function and structure d ue to increased afterload and also due to vascular and neurohormonal changes (Riaz, 2007). Several medications and strategies have been developed to decrease blood pressure in patients with hypertension and despite these measures; hypertension continues to be a challenge for some patients. Hypertension not responding to routine medical treatment has been categorized as resistant hypertension. Resistant hypertension can be defined as that blood pressure that is above the estimated goal for the age and gender of the patient, despite concurrent use of at least 3 antihypertensive drugs of different mechanism of action, i.e., different classes of antihypertensive agents. Ideally, one of the antihypertensive agents should be a diuretic and optimal doses of the agents must be prescribed. Such a stringent definition is necessary to identify patients whose hypertension can be controlled by revising pharmacological treatment and also in whom identifiable causes of hypertension exist which whe n treated can reverse the need for high doses of antihypertensives.

Human Resources Information Systems - Assignment Example oll tax laws in the context of fast changing federal policies relating to payroll taxation (Payroll tax law is really cumbersome task when the payroll system is managed internally) Decreased accessibility – When the payroll system is managed by an external outsourcing provider, the firm’s payroll services information are stored on a server outside the organization. Hence, the company finds difficulty accessing payroll figures and other employee data as and when required In case of a mistake in payroll tax deductions, retirement plan deductions, sick leave compensation, or employee benefits, it is not possible to correct the mistake fast. This issue may lead to employee dissatisfaction Employee resistance to change may be the most important risk associated with integrating a new payroll system. Employees would worry about the efficiency of a new system as it relates to their salaries, compensation, and other benefits. Hence they are not likely to accept the change. In the words of Lambert (2005, pp.1165-1167), even a well developed payroll system may fail to perform flawlessly if it is not integrated properly. Undoubtedly, such a situation will certainly result in employee dissatisfaction, which in turn may hurt overall organizational productivity. Sometimes the company’s staff may not be informed of all features of the new payroll system, and therefore they would not be able to manage the system in an effective way. However, the project management team can minimize those risks to a great extent by implementing proper change management policies prior to the actual integration of the new payroll system. The project management team should closely work with the HR team to coordinate their activities and to ensure shared efforts to convince employees regarding the necessity of the change planned. In addition, the project management team must ensure that there are skilled and experienced personnel to handle the newly integrated system efficiently. A Gantt

Analysis of Mental Shortcuts Essay Example for Free

Analysis of Mental Shortcuts Essay Being creatures gifted with reason, people are always thinking and trying to rationalize things. For each person and situation, there are different kinds of ways of thinking or mental shortcuts. One of them is Representativeness heuristic. This refers to the way a person thinks according to his insticnts and past experiences. Unlike other modes of thinking, representativeness heuristic consumes less time. It does not involve much cognitive activity. In this mode of thinking, people tend to refer to the past for decision making and judgment of occurences or events (Akent et al, 2007). Another type of type of heuristic is the anchoring and adjustment heuristic. This type of heuristic greatly relies on an anchor or initial opinion or thought about a certain object, place, or situation. Despite having other evidence before the judgment, the judgment and the trail of thought of the person remains to be hanging on to the initial thought. Unlike representativeness heuristic, this mode of thinking is slower in that more opinions are gathere before a decision is made and the rationalization concluded (Akent et al, 2007). The third kind of heuristic is the availability heuristic. This type of heuristic make use of examples for making a decision or judging an event or occurence. In addition, availability heuristic the frequency of an event may be predicted through the said example. As compared to the first two kinds of heuristic, this may be slower as there is a need to gather enough examples as basis for decision to be made. If there are no examples at hand, another mode of thinking may be utilized(Akent et al, 2007). If carefully analyzed, these modes of thinking are all faster as compared to the normal flow of thought in a persons mind. However, if measured and checked for results, all can be accurate and fast given a specific situation. For instance, the availability heuristic is faster if there are examples at hand. However, without them the other types of heuristic will prove to be more accurate and faster. Thus, all three mental shortcust prove to be helpful in a particular situation in life but not in its entirety. References Elliot Aronson, Timothy D. Wilson, and Robin M. Akert. (2007).

And Then There Were None :: essays research papers

I recently read a mystery book by the name of "And Then There Were None" by Agatha Christie. I read this book because I have read other books by Agatha Christie that were pretty well written. Ten people are invited to an island, called "Indian Island",by letters that were signed by people they had met before. When they got to the island, they found out that their host, U.N.Owen, had not arrived yet. At dinner, they heard a voice, accusing each of them of a murder, which they were all guilty of. After one of them is killed, according to the first verse of a poem that is framed above each of their beds called "Ten Little Indians", they figure out that the murderer is one of them! As more people are killed off, one by one, the group narrows the suspect list down, until only one is left alive but she figured that she would never get off the islan anyway, and she hung herself from the ceiling by putting a noose around her neck and kicking the chair away on which she was standing, but she was not the killer. One of the mysteries to this book was, of course, who killed all of the innocent people. Another mystery was that every time another person was killed a little indian figure would disappear from the edges of a serving plate. One more mystery was that every murder followed, in order, the famous poem "Ten Little Indians", which reads: Ten little Indian boys went out to dine; One chocked his self and then there were nine. Nine Indian boys sat up very late; One overslept himself then there were eight. Eight Indian boys traveling in Devon; One said he'd stay there then there were seven. Seven Indian boys chopping up sticks; One chopped himself in halves then there were six. Six Indian boys playing with a hive; A bumble-bee stung one then there were five. Five Indian boys going in for law; One got in Chancery then there were four. Four Indian boys going out to sea; A red herring swallowed one then there were three. Three Indian boys walking in the zoo; A big bear hugged one then there were two. Two Indian boys sitting in the sun; One got all frizzled up then

Tablet Computer Market Analysis (Economics)

EC180 Economics Assignment Tablet Computers Market Table of Contents Table of Contents2 Brief Introduction3 1. Factors affecting Demand4 2. Price and Income Elasticity6 3. Price Discrimination8 4. Fixed and Variable costs9 5. Scale Economies10 7. Market Structure12 8. Barriers to Entry13 Summary and Conclusion14 References14 Brief Introduction In this report, the market of ‘Tablet Computers’ will be analysed. ‘A  tablet computer is a complete  mobile computer, larger than a mobile phone or  personal digital assistant, integrated into a flat  touch screen  and primarily operated by touching the screen’ Editors PC magazine (2010).These products are gaining increased popularity in today’s world. Apple, Microsoft and Lenova are already in this market, with Apple’s popular product, the ‘I pad’ leading the market share. This relatively new market `will be thoroughly investigated using various microeconomic theories and findings . 1. Factors affecting Demand In economics, demand is defined by  the desire to own anything, the ability to pay for it, and the willingness to pay (Sullivan & Sheffrin,2003a) The diagram below shows the demand curve. Factors affecting demand would cause a shift in the demand curve.An increase in demand will cause an outward shift to the demand curve (D1 > D2), thus increasing the market equilibrium price. A decrease in demand on the other hand will cause an inward shift of the demand curve ( D1 > D3), decreasing the market equilibrium price. The diagram proves the ‘Law of Demand’ which states that quantity demanded for a good decreases as the prices increases. The following are the factors that affect the demand of a good or service. * Price * Income * Substitutes: Price of substitutes * Trend * Number of consumers in the market/ populationPrice: One of the main factors affecting demand would be the Price of the product or service. There is an inverse relationship be tween the price of the product and it’s quantity demanded. As the â€Å"Law of Demand† says, the quantity demanded for a product decreases as it’s price increases. Therefore the higher the price of tablet computers the lower the quantity demanded. Income: Another major factor which affects the demand for a good would be consumers’ income. The higher the income, the higher the demand as consumers will have more disposable income.Tablet computers are a relatively pricey and a luxurious good, therefore only consumers with a relatively high income will be able to afford them. Price of substitutes: The price of substitutes of this product would also be a factor affecting the demand for the product. A substitute good offers the same services to the consumer as good A, if the price of a substitute good would increase, the demand for the original good would increase as consumers want to pay the least they can for the same product. Therefore an increase in the pri ce of for e. g. Laptops would cause an increase in the demand for Tablet computers. 2.Price and Income Elasticity Price elasticity of demand measures the relationship between a change in quantity demanded and a change in the Price. It shows the percentage change in quantity demanded caused by a percentage change in price. This can show the extent of movement along the demand curve. PED = % Change in quantity demanded % Change in price There are a number of factors which can influence the price elasticity of a good: Availability of substitutes- One major factor of influencing the price elasticity of a good would be the availability of its substitutes. The greater the availability, the greater the elasticity.The availability of substitutes like Laptops and Desktops in this market is quite high, therefore tablet computers have a high price elasticity. Necessity or Luxury- Luxury products tend to have a greater elasticity as consumers don’t actually ‘need’ them. Neca ssity products on the other hand like ‘tobbacco’ or ‘petrol’ for certain consumers can have a very low elasticity as consumers will be willing to pay a higher price. Tablet computers are a luxurious good, therefore they have a greater price elasticity than for example petrol which could be regarded as a ‘neccassity’ good in today’s world for certain consumers.Proportion of income required by the item – The higher the proportion of income required by the product, the higher the elasticity will tend to be. This is because consumers will be more careful and hesitant to purchase a good which would acquire the majority of their disposable income. The price of tablet computers can range from around ? 300 to ? 650. Income elasticity of demand  measures the relationship between a change in quantity demanded and a change in income. It is measured by the following formulae: YED = % Change in quantity demanded % Change in consumer’s income Normal goods’ have a positive income elasticity of demand, this means that an increase in income will lead to an increase the quantity demanded as well. ‘Inferior goods’ on the other hand have a negative income elasticity of demand. An increase in income will lead to a fall in the quantity demanded for the product/service. Tablet computers are a normal good therefore it will have a positive income elasticity of demand. They can also be considered a luxorious good therefore the demand responds by rising more than proportionate to a change in income. The income elasticity of demand ill be more than +1 so demand for tablet computers would be elastic relative to income. 3. Price Discrimination As cited by Krugman (2003b, p142) ‘Price discrimination exists when sales of identical goods or services are transacted at different  prices  from the same provider. ’ Firms often use price discrimination as a method of maximizing profits. However there are two main conditions for discriminatory pricing to work 1) Differences in the Price elasticity of Demand between markets: There must be a different price elasticity of demand from each group of consumers.Firms can then charge a higher price to the group with a price inelastic demand and a relatively lower price on the other hand to the group with a more price elastic demand. 2) Barriers to prevent consumers to switch suppliers: There must be certain barriers to prevent consumers from switching from one supplier to another if the other supplier is offering the same good at a lower price. One common price discrimination method the firm could use for the sale of tablet computers would be the ‘third degree (multi-market) Price discrimination.This method involves charging different prices for the same product in different segments of the market, it is linked directly to consumers’ willingness and ability to pay for a good or service. The market can be separated by geogra phy, so a higher price can be charged to overseas markets if demand is more price inelastic than in home. In today’s knowledge world, many firms use the internet to price discriminate. Many websites can gather enough information about consumers and their buying habits to give sellers an opportunity for discriminatory pricing.One example of this would be Dell, ‘which charges different prices for the same product on its web pages, often depending on whether the buyer is a state or local government, or a small business. ’ In this case the same method can be applied to the sale of the tablet computers. 4. Fixed and Variable costs Fixed costs are costs to a business that are constant, they do not vary with the quantity of product/service produced. Variable costs are costs to a business that actually do vary with the quantity of product/service product. Fixed + Variable costs = Total costs Fixed costs: * Land purchased for production of goods, for e. . an industrial fa ctory * Salaries of staff paid on monthly rates, independent of how many hours the employees work. * Advertising: Marketing Campaign for launch of product. * Electrical equipment like lighting or air conditioning which may be kept running even in periods of low activity. Variable costs: * Cost of Raw materials * Salaries of staff paid on an hourly basis, hours can be varied therefore it is a variable cost. * Electrical equipment, as the company grows, the more the plant will be run therefore more electricity will get used which makes this a variable cost. 5. Scale EconomiesEconomies of scale in economics, refers to the cost advantages that an enterprise obtains due to expansion. A firm can experience reduced averaged costs in the long run by increasing output or ‘expansion’. There are 5 types of internal economies of scale. 1. Technical: Only large firms can afford to invest into expensive quality machinery. This makes them more cost effective by making use of large sca le capital technology which brings down cost per unit. New entrants generally don’t have that much capital to start off with, therefore suffer with high production costs and lower efficiency. . Purchasing: This is when firms buy large quantity of raw materials and get them in a lower cost per unit. Large firms in this market like Apple can buy their raw materials in bulk and get discounts from suppliers, thus achieving low production costs. 3. Financial: Larger firms are usually believed to be more trust worthy by the financial markets. They are able to negotiate cheaper finance deals and therefore get better deals at banks. Banks prefer to do business with larger experienced firms as they usually take a bigger loan therefore banks get a bigger interest.Smaller banks on the other hand can face higher rates of interest on loans. 4. Marketing: Large firms can afford the most effective and expensive types of Marketing whereas new entrant firms could find it difficult to raise en ough capital to compete with promotional and marketing methods. At times, incumbent firms can deliberately invest heavily on advertising making it difficult for the new entrants to survive in the market. This is known as ‘market power theory of advertising’ (Moffatt,2008)  . 5. Managerial: Large businesses can have specialist managers in every area.This can lead to much more efficiency therefore lower costs. The market for Tablet computers has an oligopolistic market structure, where a few large firms dominate the market (this is explained in further detail in section 7 of this report). Therefore large firms like Apple, IBM and Microsoft will enjoy the benefits of Economies of scale to a high extent making it difficult for new entrants to survive in the market. 6. Minimum efficient scale and Diseconomies of Scale The minimum efficient scale achieves production of a good at the lower possible point on it’s LRAC curve.Long run average costs are minimized at this point, and it is not possible for the firm to produce the good at any lower cost. The efficiency is maximized at this point. The MES can be used to determine the most likely market structure of the market. For example, if the MES is small compared to the overall size of the market, then will then be a large number of firms in the market. The market will be more contestable and firms would behave in more of a perfectly competitive manner. (Carlton and Perloff, 2005) Diseconomies of scale occur when a business grows so large that the costs per unit increase.This often only happens in extremely large scale production. A business can experience difficulty in communication as it expands. There are more workers and more managers. Communication has to be passed down many levels of hierarchy; therefore messages can be distorted leading to workers being unsure of what they have to do. Multi-national firms have production in different countries which also makes communication more difficult wi thin the business. To avoid this problem very large businesses often de-merge and break themselves into smaller units.Workers down the order can feel demotivated playing a small role in a very large firm. They can feel unimportant which eventually leads to more sick days off and therefore decreasing efficiency of labour. In the case for the tablet computer market, there are already very large incumbent firms like Apple and Microsoft who have grown and diversified themselves into different markets. These firms are so large that it is likely that they have diseconomies of scale. New entrants can therefore see this as an opportunity. The diagram below illustrates Economies and Diseconomies of scale.It is however important to understand that not all firms will experience diseconomies of scale. Therefore it is possible the LRAC (Long Run Average Costs) curve is just downward sloping. 7. Market Structure Market structure are the competitive characteristics of the market. They are used to determine the potential for profits and market efficiency. There are four main types of market structures:  perfect competition,  monopoly,oligopoly, and  monopolistic competition. ’ The market structure of a firm is determined by various factors.A summary of the four basic types of markets in and their key characteristics is shown below using this table. Charectristics| Perfect Competition| Oligopoly| Monopoly| Monopolistic Competition| Number of firms| Many| Few| One| Many| Type of product| Homogenous| Differentiated | Limited| Differentiated| Barriers to entry| None| High| High | None| Economic Efficiency| High | Low | Low | Low| After analysing the tablet computer market and its characteristics, the market structure of tablet computers seems to be oligopolistic. An oligopoly is a market structure in which a market is dominated by a small number of sellers.The tablet computer market currently seems to be dominated by large firms like Apple, Lenova/IBM, HP who own a l arge percentage of the market share. As mentioned earlier in this report, the barriers to entry in this market are fairly high which is one of the characteristics of an oligopolistic market. At the moment, 8. Barriers to Entry Barriers to entry are obstacles that make it difficult for new entrants to enter the market. The higher the barriers to entry, the lower the threat of competition. The main barriers for the tablet computers market would be the following: 1.Economies of Scale: As mentioned previously in Section 5 of this report, economies of scale could also be a barrier to entry in this market. Large incumbent firms like Apple and Microsoft have significant cost advantages which allow them to produce their tablet computers at lower costs than small or new entrant firms. Therefore new entrants would have lower profit margins making it difficult to survive in the market. 2. Customer Loyalty: Another advantage the incumbent firms would have in this market would be having customer loyalty.Large firms like Apple and Microsoft already have existing customers in the market who are loyal to their brand. Especially with the presence of Apple which definitely has high customer loyalty. This would make it extremely difficult for a new firm to enter the market as many of the consumers would still rather stick a trust and more experience brand. 3. Sunk Costs: One major barrier to entry would be the existence of ‘Sunk Costs’ in this market. Sunk costs are the costs to a business which cannot be regained when exiting a market.A new entrant to the tablet computers market would have to invest heavily in Advertising and Promotion methods. In case the firm doesn’t succeed and decided to exit the market, the cost of this investment cannot be retrieved. The sunk costs involved in this market could be high due to large incumbent firms like Microsoft and Apple’s existence. 4. Advertising – Apart from advertising being a sunk cost, it can also play another role in make it difficult for new entrants. This was explained in Section 5 of this report ( Market power theory of advertising ) 5. Patents Summary and ConclusionThe market for tablet computers is an oligopolistic market. Large firms like Apple, HP an IBM seem to be owning the majority of the market share which could it make it very difficult for new firms to enter and survive in the market. The market is also relatively elastic which could limit profits. In addition the existence of high barriers to entry and economies of scale benefits enjoyed by incumbent firms will not help new entrants. Price discrimination is possible for this product, however only to a certain extent.

Importance of Oedipus and Teiresias’ Conversation Essay

Oedipus Rex, a classic Greek play, was written almost 2500 years ago by a famous playwright named Sophocles. The play focuses on finding Laius’ killer but through the process, Oedipus finds out who he truthfully is. In Scene one lines 284-448 Oedipus is speaking to Teiresias a blind prophet, he asks Teiresias to reveal Laius’ killer. This passage has defining characteristics that are important to the play as a whole, which can be simply conveyed on stage. This passage helps develop and make the play more intriguing by showing how blind to the truth Oedipus really is. Before the beginning of the play Oedipus saves the people of Thebes from the curse of the Sphinx and becomes king virtually overnight. He proclaims his name proudly as though it were itself a healing charm â€Å"I have come myself to hear you-/ I, Oedipus, who bear the famous name.†(Prologue 9-10) what Oedipus does not realize is that he had killed Laius son of Labdakos on the way to the Sphinx. The play is based on finding the killer of Laius. Oedipus wants justice done and for the murderer to be banished from Thebes. Oedipus does what he can to make this happen. This includes a conversation with Teiresias. The passage starts off when a boy leads in the blind prophet Teiresias to Oedipus. Oedipus then begins to beg Teiresias to reveal who Laius’ murderer is, but Teiresias answers only that he knows the truth but wishes he did not. Puzzled at first, then angry, Oedipus insists that Teiresias tell Thebes Thebes what he knows. Provoked by the anger and insults of Oedipus, Teiresias begins to hint at his knowledge. Finally, when Oedipus furiously accuses Teiresias of the murder, Teiresias tells Oedipus that Oedipus himself is the curse on Thebes that he is in search for. Oedipus dares Teiresias to say it again, and so Teiresias calls Oedipus the murderer. Oedipus criticizes Teiresias powers wildly and insults his blindness by saying â€Å"You child of endless night! You can not hurt me or anyone who sees the light† (Scene I, line 359-360), but Teiresias only responds that the insults will eventually be turned on Oedipus by all of Thebes. Driven into a fury by the accusation, Oedipus proceeds to concoct a story that Creon and Teiresias are conspiring to overthrow him. The leader of the Chorus asks Oedipus to calm down, but Teiresias only taunts Oedipus further, by saying † I can say that you, with both your eyes, are blind: You can not see the wretchedness of your life, Nor in whose house you live, nor with whom. Who are your father and mother? Can you tell me? You do not even know the blind wrongs that you have done them, on earth and the world below.† (Scene I, line 399-404) This statement both infuriates and intrigues Oedipus, who asks for the truth of his parentage. Teiresias answers only in riddles, saying that the murderer of Laius will turn out to be both brother and father to his children, both son and husband to his mother. Teiresias is then led out by his page and Oedipus enters the palace. Oedipus remains blind to the truth until he can deny it no longer. As Teiresias told Oedipus: â€Å"To the children with whom the murderer lives now he will be/ Brother and father-the very same; to her/ who bore him, son and husband- the very same.† (Scene 1, line 441-444) When it became evident to Oedipus that he had killed Laius his father and married his mother Jocasta his life took a turn for the worst. It is at this point in the play where Oedipus learns that knowledge and a vision of his past, which brings evil, pain, and suffering into his life. Oedipus is not worried just for himself but also for his children who will now have to live in shame of their father. In the ending scenes of the play Oedipus takes Jocasta’s broach and punctures his eyes making him blind to all that was around him. This is ironic because in the passage in scene two Oedipus could see with all his eyes, but his mind was ignorant to the truth, and even though Teiresias was physically blind, he was always able to see what Oedipus refused to. The incident involving Oedipus and Teiresias shows how the power of ones mind can far exceed any physical ability of knowing the truth. Within this scene there are many different ways the script can be interpreted. Sophocles is not to explicit with written stage direction so  there is room for some  imagination. The scene starts off with Oedipus in centre stage and Teiresias being led to him by a page. Oedipus costuming is elaborate and of many colours, while Teiresias is a simple man dressed in brown, with a cane used to help guide him. Oedipus is higher on stage then Teiresias it is almost as if Oedipus is speaking down to Teiresias. During their conversation, Oedipus becomes desperate to find the murderer of Lauis and slowly comes down from the stage closer to Teiresias. As Oedipus is doing this his fate is slowly being diminished. He is slowly walking towards the truth that Teiresias holds. When Teiresias tells Oedipus the truth that he is in search for Oedipus becomes upset and says to Teiresias â€Å"Damnation/ Take you! Out of this place! Out of my sight!† (Scene I, line 418-419) Oedipus would start to show his power at this point by forcing himself on Teiresias and throwing his hands in the air displaying his anger. Teiresias being blind would not see all of this anger. As Oedipus gets fed up with the situation he asks for Teiresias to leave and enters the palace. Even though this play was written 2500 years ago, Oedipus Rex is still a play in which one can relate to. Many people in society today are blind when is comes to their past and to certain events which affects them in a negative way. People think that the only was to conquer this blindness is to seek out the truths that they are looking for, whether it is in their past or their present. Oedipus’ conversation with Teiresias has the defining characteristics of blindness and sight that help develop the play as a whole. The script does not give much stage direction which leaves room for the reader to use their imagination. All these components of the passage add to the understanding of the passage and the play as a whole.

discuss why some skin disorder essays

discuss why some skin disorder essays Discuss why some skin disorders can show a mosaic pattern of expression and others do not? In May 1998, an international symposium was held in Marburg, Germany, to discuss the growing research interest in Mosaicism in Human Skin. At this symposium, the work of Alfred Blaschko and Rudolf Happle was recognized for its contribution to the field [2]. In 1901, Blaschko wrote his seminal paper on what became known as Blaschko lines, a set of fountain-like patterns on the back, whorls on the abdomen and linear stripes on the limbs. He proposed that these lines had their origins in embryonic development and in 1977, Happle linked these lines to a dateable embryonic event; X-inactivation. [9] The last 30 years has seen an increasing interest in this field, with proposed theories of X-linked skin diseases and the definition of the term mosaicism to categorize them. A genetic mosaic is an organism composed of two or more genetically different populations of cells that originate from one genetically homogenous zygote. The incredible diversity of cutaneous patterns have been classified into four categories; the line of Blaschko, the checkerboard pattern, the phylloid pattern and a patchy pattern without midline separation. The causes of these forms of mosaic expression have two major classes indicative of their genetic mechanism. Functional mosaicism results from the Lyon effect of X-inactivation. Genomic mosaicism is a product of autosomal mutations that may be lethal or non-lethal. [3] Table 1 from Moss summarises many of the mosaic linear dermatoses. [7] Some X-linked skin diseases are found predominantly in females as the mutation exerts a lethal effect on hemizygous male embryos. [8] Such diseases, like incontinentia pigmenti, focal dermal hypoplasia, X-linked dominant chondrodysplasia punctata, oral-facial-digital syndrome type I and CHILD syndrome are a few examples of X-linked male-lethal mutations. Females are usually carriers and sh...

Ways to Reduce Fluoride Exposure

Ways to Reduce Fluoride Exposure If youre looking to reduce your intake of fluorine and fluoride (one is the element, one is the ion, both are toxic), it may help you to know what everyday products contain them and what steps you can take to limit your exposure: Dont drink unfiltered public water. Assume its fluoridated unless you know otherwise. Most home water filters will not remove fluoride.Dont take fluoride supplements.Try to limit drinking soda because its generally made with fluoridated water. Reconstituted fruit juice, beer, and wine also tend to be made with fluoridated water. Read labels on bottled beverages and look for water purifed using reverse osmosis or distillation. If those processes are not specifically named, assume the water is fluoridated.Read the label on bottled water. Again, look for water purified using reverse osmosis or distillation.Consider using unfluoridated toothpaste.Avoid drinking black or red tea. Black and red tea come from two different types of plants, but both leaves naturally contain high amounts of fluorine. If you drink tea, brew it yourself, using unfluoridated water.Choose organic fruits and vegetables since the US National Organic Program does not permit the use of the pesticides that leave high fluoride residues. Expect tinned fish and canned food items to contain fluoride.Avoid or limit your consumption of mechanically deboned chicken in any form, including chicken nuggets, canned chicken, and baby food. Traces of fluoride (from bones) remain from the deboning process.Fluoride may be used as a preservative in many products.Sometimes you will be able to see this on the product label.Avoid black or red rock salt or items containing black or red rock salt.Avoid using chewing tobacco.Avoid long term use of medications that contain fluorine.If you use a fluoridated toothpaste, rinse your mouth with water after brushing your teeth.If you need anesthesia, ask your doctor about options using drugs that do not contain fluorine.Avoid overheating teflon pans while cooking, as some of the teflon (a fluorine compound) may be released into the air.

Project maangement - Essay Example This paper will evaluate the various reasons why organizations are using Project Management to achieve their strategic objectives. It will focus on the view of projects as investments rather than being likened to investments. The paper will evaluate the application of the various doctrines of strategic project management that project managers use to accomplish the strategic objectives. Project management generally takes the form of a decision tree (Fig. 1). Goodwin and Wright, (2009) observe that after developing the strategic objectives, the managers evaluate the current situation or status of the organization. This is a starting point that is necessary to determine the next course of action. Project management is therefore preferred because it answers the question of whether the organization has attained its maximum capacity (Chapman and Ward, 2003). If not, the managers engage in assessing the constraints to establish if their cause is known or not. From this point, if the causes of the constraints are known, ways of alleviating them can be determined. If they are not known, investigations are undertaken. Such procedures help organizations to apply a straightforward approach to solving problems (Kendrick, 2009). Many contemporary organizations undertake different projects depending on their significance to organizational productivity (Dale et al. 2007). In many situations, different departments in the organization come up with projects that compete for the available finances. They have different impacts on the overall organizational performance and priorities need to be set depending on the organizational needs. Project management is significant in making strategic choices to support the projects that need immediate attention as well as those that can be implemented in future (Kemp, 2006). Strategic project management integrates major organizational processes of strategic planning, tactical setting of

Fukushima Nuclear Plant Disaster Research Paper

Fukushima Nuclear Plant Disaster - Research Paper Example If left unchecked, these can result in casualties equaling or even exceeding the body count of the previous natural disasters. This being the case, this study intends to take a look at the specifics of the incident – what occurred, as well as how and why. Concluding the study shall be a brief reflection on the incident and its immediate and distant aftermath. Table of Contents Abstract 2 Introduction 4 The Disaster 5 Radiation – The Deadly Consequences 8 Reflection 14 Conclusion 15 References 16 Introduction The disaster that occurred at the Fukushima I Nuclear Power Plant last March came right on the heels of the then-recent earthquake and tsunami that rocked the nation. The said occurrence was a consequence of these natural calamities, and was in fact joined by other nuclear accidents all over Japan. However, the one in Fukushima stands out as the largest. In fact, the magnitude of the disaster is said to be comparable to the tragedy at Chernobyl decades ago (Thomson- Reuters, 2011). The comparison to Chernobyl came courtesy of experts on the subject, which should say something on how catastrophic the Fukushima incident was. On the International Nuclear Event Scale, its rating was a 7, exactly the same as that of Chernobyl, whereas the Mile Island Disaster trailed behind at 5. As shall be explained below, the Japanese government tried to dismiss and downplay the incident to extent, but was eventually forced to concede to its magnitude. Fortunately, casualties resulting from the immediate disaster were relatively few. For sure, the natural calamities that preceded the disaster claimed over 9,000 more lives than the accident at Fukushima. Even then, the latter was still hardly equivalent to a slap on the wrist. The death toll immediately following the disaster numbered at 47. Two of these were Fukushima plant workers unlucky enough to get caught in it, and who sustained multiple external injuries before ultimately dying of blood loss. The other 45 who perished had been patients at an evacuated hospital in Futaba, and who had mostly been suffering from dehydration and starvation. Unfortunately, though, the relatively low immediate body count might be balanced out by an even bigger death toll if things are left the way they are now. As with the disaster at Chernobyl – and, more to the point, the bombings of Hiroshima and Nagasaki – the area remains irradiated, and cleanup efforts continue up till today. The threat of radiation is arguably the most terrifying thing to have come out of the disaster. The other consequences which have resulted from the accident cannot be seen by human eyes. However, these are unmistakably there, and can in fact result in a much higher body count if left unchecked. Even as it is now, the constant threat of being irradiated has rendered numerous surrounding villages and neighborhoods uninhabitable, which by itself is already a monumental setback for the unlucky ones living there (Maeda, 2011). The Disaster As already noted, the Fukushima disaster ranks among the biggest nuclear catastrophes in recent history, easily at par with or even exceeding what happened at Chernobyl (Thomson-Reuters, 2011) though still on a somewhat lower scale compared to the Nagasaki and Hiroshima bombs. Considering that multiple reactors were involved at Fukushima, in contrast with
