Essay Sample Is Nuclear Energy Really Safe

Nuclear energy has a lot of myths and it makes people wonder if it’s really safe or not for nature and all living beings. Greenpeace representatives are sure that there’s no place for nuclear energy and nuclear pollution in this word. If we don’t see something with our eyes, it doesn’t mean it doesn’t exist. However, nuclear energy is cheap and it’s popular in many countries nowadays. Considering the environmental effects of nuclear power plants can give the true answer to the popular question regarding the safety. The dangers of nuclear power plants We all can remember or find the information online about the tragedy in Chernobyl where thousands of people suffered from so-called safe nuclear power. The radiation killed people and it was just the result of the release of the nuclear materials in the air because of an explosion. People were there and most of them didn’t survive. There’s always a chance of a huge catastrophe on any nuclear plant. There are no nuclear power plant safety systems that are used globally. There are no firm solutions that could guarantee the safety and the stable operation of all the nuclear plants in the world. No matter what country you live in. It doesn’t matter if you don’t have nuclear plants in your city or even state. The radioactive dust and clouds will reach you at any part of the globe and they will fall down on the ground in a form of rain drops. Nothing can clean the ground and the things from radioactive parts. How does the plant work? Is nuclear power safe for the environment? They all produce wastes that are radioactive. The wastes are buried under the ground in special boxes and containers. However, these wastes leak into the ground and kill everything around. The consequence of the leakage can be very sad if there are any water bodies on or under the surface of the ground. Radioactive parts don’t smell and you cannot see them. The safety of nuclear power plants Radioactive parts surround us all the time. If we take the territory of the US and its residents, they get less of half of one percent of the radiation from nuclear plants. People can get radiation from: Coal; Flights in airplanes; Bananas and fruits. And you can get more radiation from these things than from nuclear power. It’s obvious that a working plant cannot hurt anyone. Modern configurations and designs of the plants let them work stable and smooth. An explosion cannot happen thanks to dozens of preventive tools and techniques that are used on every plant. A plant is not a bomb anyhow. A regular nuclear plant doesn’t emit any harmful gasses or other wastes during its workflow. It doesn’t require using other types of energy and it saves the atmosphere. Other plants producing energy provide more harm of the environment. It’s safe as there are no facts of injuring a single worker at the plants on the territory of the US for the last fifty years. So working there is at the same level of safety as working in a regular office. Real environmental benefits of nuclear energy A great benefit is recycling the wastes that nuclear plants produce. About 90-95% of them can be recycled and this makes the nuclear energy safe and secure for the environment. There are a lot of myths concerning the wastes and that they leak into the ground and spoil everything around. It’s not true. If we take all the wastes that have been produced on the territory of the US for the last fifty years, we will be able to put them on one football field. There are no wastes and no emissions into the air. Is nuclear power clean? The answer is obvious now. If more people could get reliable information about the nuclear power and the work of the plants, they wouldn’t be so afraid of it. However, the safety also depends on the smooth and clear workflow of the staff that works on the plant. The reason for the explosion in Chernobyl in 1986 was a mistake made by the personnel. Many Americans are afraid that they will have to experience one more Chernobyl in the future. There are no real reasons to worry about as the type of the reactor that is used in the US differs from the type of the reactor that was used in Chernobyl. That type was only used on the territory of the Soviet Union, so the safety of the equipment that is used in the US is also of high quality. Is nuclear power safe? Yes or No? There cannot be one answer as opinions of different organizations and different people are not the same. Greenpeace representatives are sure that nuclear power is an obsolete thing that shouldn’t be used in the modern world. And there are opinions and proofs that nuclear plants don’t pollute the air and it’s one of the cheapest variants to produce energy for the population and other plants that work on the territory of the US. One single answer is a wrong answer to the question whether the nuclear power is safe. There were cases of real tragedies that occurred in the past and killed many people. And there are the figures that show that no plants will ever explode in the future. We can assume that the proper approach to the staff workflow and the operation of the plant can guarantee smooth and safe coexistence of nature and nuclear plants one next to another. The right safety measures in nuclear power plant can predict and prevent any kind of catastrophe. However, no one can predict the future of nuclear plants in fifty or one hundred years. More and more people start looking around and asking questions about the safety of all the nuclear plants that work in the US. Such awareness will help defeat all the myths and choose the safest variant of generating energy.

What Is Anthropology During This Semester, I Grasped A

What is Anthropology? During this semester, I grasped a better understanding of human-kind through the explanation of culture and biology. I learned a lot about how people live in different regions of the world and how cultures are linked. I believe that because we questioned what we knew about human diversity in the past, we have gained a better idea of the people and the world around us. People like Sebastian Munster, who drew maps of new lands and kept a catalog of human diversity, Caption Cook, who find new regions from his voyages around the world, Johnaan Blumenback, the first anthropologists who divided the human species through common origin, E.B. Taylor, who could express stages of cultural evolution and the progress, and so many†¦show more content†¦Some of the methods I used during my ethnographic research consisted of interviewing, observing, detailed records, unobstructed view, and a written account. I wanted to keep each interview in chronological order, so I a m going to talk about events in the order in which they happened in her life. One of the first interviews I conducted of my mother was when I took her to her doctor’s appointment on Friday, March 5th, because of procrastination, I had little time to write this paper, so I conducted interviews whenever and wherever I could. We first talked about her ancestral background or genealogy, which includes her parents, grandparents, and great grandparents on both sides. On Debra’s mother’s side of the family or maternal side, she was told that her great grandparents were born in Portugal, that they migrated from Portugal, approximately before 1910 in search of the â€Å"American Dream.† They migrated for the better opportunities that were present in the united states at the time, she is not quite she exactly when and why but the gold rush could have been a possible reason. Her great grandmother, name unknown, was 100% Portuguese and her great grandfather, name unk nown, was 100% Portuguese. Debra recalls at the age of 5 years old, she had an opportunity to meet her great grandmother who at the time she remembers being bedridden. She only remembers meeting her one time and is unsure of the reason why she was not able to see her more than just that once.

No Doubt - Rock Steady free essay sample

In1995, No Doubt was on top of the world. With their third album TragicKingdom going multi-platinum thanks to hits such as Dont Speakand Just A Girl, it seemed nothing could stop them. The music worldsat on the edges of its seats for five long years for last years relativelydisappointing Return of Saturn. But before critics could push NoDoubt into the one-hit-wonder category, the band released RockSteady in December, a mere 18 months after its predecessor. Already,the first single, Hey Baby, has become a staple on radio stationsacross the country, as well as on MTV and VH1. The song, a shout out to all thegroupies who try to seduce Stefanis bandmates bassist Tony Kanal, drummerAdrian Young and guitarist Tom Dumont is typical of the catchy, synth-drivenpop of Rock Steady. The new album marks a departure from NoDoubts signature style and creative process, making this a mix of classic newwave sounds, hard-driving hip-hop beats and slinky Jamaican dance-hall. We will write a custom essay sample on No Doubt Rock Steady or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The mainreason for this, I believe, is because of the many collaborations the bandindulged in, including Dave Stewart of The Eurythmics, Prince, U2 mixman NelleeHooper and the Cars Ric Ocasek. At the first spin of RockSteady, one might be taken aback a bit, recognizing that this new sound isclearly steering away from the sound you might be used to from them. But a fewmore listens will bring back the memories. The style may have changed, butthe lyrics are still pure No Doubt. Any fan of their music will know that Ms.Stefani just cant keep herself away from the relationship genre insongwriting, giving each album its own distinct theme, if you will. RockSteady is no exception. In fact, I think Trouble in Paradisewould have been a better title. But, to be honest, the albums theme was the lastthing on my mind while listening to it. What was on my mind was most ofthe songs I couldnt get them out of my head. The chorus to the title trackappears twice, as the intro, and of course, as the last track. Its a catchylittle chorus that will have you humming. Detective also possessesthis quality, with the chorus thrust at you right at the beginning, foreshadowingthe songs catchiness. I think one of the greatest aspects of this albumis its diversity. With other albums, its strictly ska or rock. RockSteady is neither. You hear straight-forward pop (Making Out),?s new wave (Dont Let Me Down), a little rock (PlatinumBlonde Life), dance-hall reggae (Start the Fire), and justplain old good music. This is definitely No Doubts greatest effort. RockSteady proves that there is no doubt (no pun intended) that No Doubt willbe around for a long time.

Maintaining and improving operations

Abstract The supermarket industries are among the largest economic upholds in the U.S. The expansion of the customer base is a noticeable consistent growth of the supermarket industry that deals with diverse products. The global expansions plans require enhancement of more effective promotional strategies in order to overcome the economic challenges. Comprehensive financial predicaments affect the consumer behaviours and, therefore these end-users tend to change their purchasing styles due to a lack of trust and confidence.Advertising We will write a custom essay sample on Maintaining and improving operations specifically for you for only $16.05 $11/page Learn More Financial strains also causes the consumers to demand for lowering of prices and at times the situation causes shift of the consumption patterns, for instance the expenditure tends to incline more on the food products over the non-edibles. This is mainly attributable to the reduction of dispos able income, and eventually such kind of trend affects the industry’s financial performance. This report focuses on the performance of food industries with a special attention to Wal-Mart as a global retailer. Overview of Wal-Mart Recent financial recessions affected the economic routine of Wal-Mart, but the firm came through and managed to improve the economic global presentation. The reduction on the number of clients visiting the stores globally during the financial crisis of 2007 did not pull back the overall performance. According to Hoovers AD B Company (2010), Wal-Mart stores were still able to pull out a marginal sales growth of 0.7%. This resulted to only a minimal reduction in the firm’s financial performance. It equally came about due to the consumer trust, but one of the major concerns that various global stores must deal with connects to the safety, quality and value of the edible products. Different states’ administrations as well as the nongovernm ental organizations have had to heighten the food regulation policies within the industries. A good example is directive that governs refrigeration, which ensures that firms in the food retailing industries observe various environmental concerns. Extra tax policies are also set to ensure compliance with new guiding principles. Six Components of Wal-Mart’s Supply Chains Information The effectiveness of a supply chain depends highly on the accuracy and speedy flow of information from the consumer to the production line. The competitiveness in the food industry has seen Wal-Mart incorporate technology into its operations as a measure of enhancing operational efficiency. Innovation demands for a streamlined information flow through computer networks as a measure of enhancing proper movement of inventory as per the demands. Information also entails implementation of the accounting systems, inventory management systems, systems for planning resources and global communication networ ks. Wal-Mart growth also has a connection to its ability of soliciting and facilitating online transfer of goods and services. This enables the firm to provide the customers with the right products as per the demands at the right time.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Production To attain a competitive advantage, Wal-Mart differentiates some of the food products according to categories for instance, the stores ensures differentiation according to buyer’s age. One question the industry has to answer is what does the consumer want or demand? The key importance of addressing production falls upon the quantity and type of products. The firm has to know which and how many parts of production require outsourcing form competent suppliers. The firm must face up to needs of finding the exact or approximate quantity required for each of its stores without a compromise on quality and customer satisfaction. The resource planning team can be of great assistance in this case since there is need for proper schedule to meet demands, control of quality, and balance of the workload beside the overall maintenance of the production line. Supply The resource planning system of the industry is strongly required to ensure enhancement of supplies. To guarantee that supply strategy succeeds, Wal-Mart invests in market research. The strategy makes certain that there is continuous value addition to the firm’s products and that the supplies go as per market demands. Repetitive customer market research enables Wal-Mart to identify the varying consumer tastes and preferences particularly in connection with food products. Supply management also requires value analysis since changes on demands require products analysis and equivalent adjustments. The main challenge in this case is the ability to attain as well as maintain competitive edge by ensuring supplies integrates to demands especially on matters concerning tastes and preferences. Inventory Inventory management is ability to determine the amount of products required in the warehouses. The challenge that Wal-Mart must deal with in this case involved management of the right quantity of inventory. Too much inventory means more costs, while too little can sabotage firm’s growth due to lost consumer trust, therefore the firm must meet demands. Management of optimal stock levels at each supply chain store ensures satisfaction, thus enhancing trust and fluctuation of demands as required in retailing industries. A resource planning system at the order points can assist in monitoring of levels to control supplies. Inventory levels are critical since excess production or supplies can affect other business operations mechanically or financially. Location The global investment requires close monitoring of the demand trends and preferences. Wal-Mart has strategized its production and supply units t o support distribution and inventory management.Advertising We will write a custom essay sample on Maintaining and improving operations specifically for you for only $16.05 $11/page Learn More Long-term plans of a retailing industry such as Wal-Mart requires practical strategic location of production and stocking facilities, for instance the light and non-technical products can be closer to the end-users. Heavier products demands for bigger production and supply units thus must be closer to the raw materials. The decisions concerning location also require a resource planning system for close analysis especially during global distribution. Transportation According to Levy and Weitz (2001), transport decisions have a close relation to inventory management and consumer demands. Various means of transportation differ in terms of cost, cargo quantity and speed. A good percentage of the production cost fall within the transportation schedules; therefore, use of the right channel is critical. The transportation mode must meet the inventory measures for effective supply as per the demands. This is often a strategic operational decision that ensures smooth supply of goods. Global Operation Processes of Wal-Mart Currently, there are high hopes over future performance of the industry considering that there are notable improvements of the global economy after the 2007 recession. Wal-Mart is a global retailer with global reach of potential clients and ability to monitor as well as react on time to overcome possible economic crisis. Global accomplishment also enables the firm to financially strategize and hence recover its other financial sectors. Wal-Mart’s Approach to Solving Operational Problems One of the main challenge the firm faces is ability to form a financial defence over its ability to attain global reach through expansion of retail stores to different countries. Financial commitment and strategies guarantees the attainability of global expansion. The firm must ensure that the chain stores acquisition strategy meets the quality policies. Wal-Mart formulates acquisition of stores through analysis of demands at the domestic markets. The global expansion increases financial recovery while picking a strategy that lowers the financial costs. Globally, Wal-Mart has had financial difficulties over remittances for operations due to the fluctuation of the foreign exchange rates. The drop on Wal-Mart’s financial growth in the recent years is therefore attributable to reduced financial performance. However, stability of the foreign exchange rate causes the global economic recovery of the industry (Wal-Mart annual report, 2010). A resource planning system can monitor the economic recession by finding possibilities of future reductions on consumers’ disposable income, thus reduced levels of consumption. The system can also assist to monitor consumption trend among the end users and consequently advice o n upgrading choices (Levy and Weitz, 2001).Advertising Looking for essay on business economics?

myxococcus xanthus essays

myxococcus xanthus essays The bacteria Myxococcus Xanthus is a decomposer that moves and forms fruiting bodies to reproduce. These fruiting bodies are mounds that grow into mushroom cloud like bodies, where cells differentiate on the inside to form small spores that are heat and desiccation resistant. In her discussion of Myxococcus Xanthus, Dr. Hartzell addresses various complexes that make flagella-less movement possible for the bacteria. The researchers traced cell movements and found that Myxococcus Xanthus moves at a rate of 2.5 micrometers per minute. A rate that is slower than continental drift (3 micrometers per minute). Cell movements occur in two different forms: social (moving in groups of cells) and adventurous (individuals moving). Movement is found to be gene determined. Two genes were found to be required for any movement: mgl A and mgl B. Furthermore, there are specific genes required for social movement and specific genes required for adventurous movement. Mgl A, a magnesium dependant, is a GTP-ase (a protein that binds and cleaves GTP to GDP) like Ras. It was found that mgl A was necessary for development of the fruiting body and for movement, but not for growth of the cell. When mgl A binds to GDP, it is inactive. However, when it binds GTP, it is active. Then mgl A was sequenced and found to have one of the Aspartine amino acids exchanged for a Threonine. If mgl A was mutated to replace Threonine with Asoartine (the way it is in most Ras proteins), no movement or formation of the fruiting body occurred. Also, induced activation of this protein (forcing GTP to bind to it) causes movement, but not development of the fruiting body. The calcium dependent mgl B protein is also required for movement. Found right next to mgl A and transcribed at the same time, mgl B is believed to be a guanyl nucleotide release factor (REM for short). REMs facilitate the release of GDP from Ras type proteins (mgl A) so that it can bind more G...

International Economics Essay Example | Topics and Well Written Essays - 1250 words

International Economics - Essay Example Social and cultural characteristics also impact the production techniques since the stock of trust among Indians facilitates the maintenance of socially held knowledge that, in turn, allows the social organization of the economic activity of carpet making. In India, values, ideas, human relationships and knowledge of carpet making are transmitted from one generation to another as part of the robust Indian culture. Conversely, the carpet production process in the US is characterized by mechanization of most processes. 2This allows for large-scale production as a single carpet producer uses massive amounts of fiber each day. Resource endowment, in the US, includes massive amounts of financial and intellectual capital, high entrepreneurship and robust technologies. Additionally, income levels are relatively large, enabling entrepreneurship and the establishment of huge companies that churn out massive quantities of carpets throughout the year. Essentially, resource endowment, in the US, including land, capital, labor and entrepreneurship, is quite prosperous. Social and cultural characteristics of the US that impact carpet production include an appreciation for formal training and education, which results in highly skilled and specialized human capital essential for the production process. Question 2 Carpet production is one of India’s oldest industries, dating back to the Mughal Dynasty. However, carpet production centers on the individualistic skills and knowledge of a weaver rather than collective appreciation of carpet making acquired through formal education and training. Due to immediacy to furnishing product, several carpet manufacturing centers have developed across the country. Carpets produced in India are mostly exported since the Indian market for carpets is quite small as a result of the low purchasing capacity of local players. Presently, India’s carpet export is worth Rs.2600 crores while the local market size is approximately Rs.200 c rores. 3The industry has high growth potential as exports increased by 42.23% between 2004 and 2007. 4However, the industry is marred by challenges such as poor market channels, resulting in ignorance within the Indian market. 5On the other hand, the carpet industry in the US is highly developed. The industry shipped 1.969 billion square yards of carpet, in 2003; this was worth approximately $12 billion. Carpet shipments increased to 2.3 billion yards in 2004, demonstrating the massive potential inherent in the US carpet production industry. Presently, the US meets at least 45% of the world’s carpet needs. 6The US carpet industry is characterized by innovations and technological advances that allow for large-scale production of highly-priced goods. Technological progress is one of the primary reasons behind massive growth in the US carpet industry. The US carpet industry is highly organized, allowing for sufficient knowledge in the domestic market. 7 As a consequence, the US effectively meets at least 90% of its domestic carpet needs. Question 3 Latent demand for carpets in the USA pushes the country to become a primary importer of carpet despite being an efficient carpet producer. This is because carpet production, in the US, has been unable to offer complete satisfaction to all domestic needs and wants, resulting in a gap between what is available and desirable. The local US market has a high desirability for hand woven, Indian carpets, which are considered stylish and sophisticated. Conversely,

Pricing Scheme - Research Paper Example The United States stock market is the place where individuals buy or sell stocks. The markets’ sellers sell the companies’ products to the eager stock buyers. Similarly, the stock market sellers offer to buy the stocks sold by the stock owners. Economics plays a major role in the sale or purchase of the stocks. The sellers prefer to sell more stocks at higher prices. Similarly, the buyers prefer to buy stocks at lower prices. As the prices rise, the current and future customers’ demand for the products decline. When the prices rise, the supply of the products increases (Arnold 312). The current research delves on the pricing of the Verizon Company’s stock market prices. The stocks are sold and bought using a controlled computerized software program. The stock market includes the services offered by the stock market agents. The agents are selling the stocks of the communication services company, including Verizon (Morningstar 1). Table 1 shows the prices of the Verizon stocks sold in the digital stock market. The stock market prices show the equilibrium price. The equilibrium price is the price agreed upon by both the Verizon stock sellers and the Verizon stock buyers (Morningstar 1). There are economic interpretations of the stock market prices (Arnold 312). In terms of the January 10, 2014 equilibrium price, the sellers and buyers of 11,454,003 stock units agreed to sell (exchange) the stocks at $ 47.75 per stock. The price dropped from the prior week’s $48.42 stock market price. The price drop was instituted in order to increase the drop in the demand for the Verizon stocks. The 11,454,003 stock units sold show the decline from in the demand for the Verizon stock. The prior week’s stock market units sold (exchange) was higher at 12,045,205 units (Morningstar 1). Similarly, the January 31, 2014 stock market price of the Verizon stock was $48.02 each. At this price, there were 18,558,798 stock units sold.
