Nuclear and Coal Power: Which is Better

Today we are living in a world that is becoming increasingly more environmentally conscious, yet consuming more energy than ever. Having such high-energy demands creates many environmental issues, such as pollution, land exploitation, and the consumption of finite resources. In order to begin a true conservationalist society, solutions must be found that satisfy our growing energy needs, and reduce our impact on the environment. Right now we have many sources of energy, of which nuclear and coal are the predominant energy sources of today. Since these are the major energy sources a logical step in the solution process is discovering the pros and cons of each source. Coal energy is very inexpensive and easy to recover, and accounts for approximately 40% of electric energy produced worldwide, down from 74% in 1937. In order to derive energy coal must first be mined, then transported to another location where the coal will be burned, which results in the release of toxic pollutants into the atmosphere. Coal energy is a significant contributor to both global warming and acid rain because of its high carbon and sulfur content. There also exist the harmful effects of both mining for the coal and of transporting the bulky product. There are several ways to mine for coal, the most significant of which are strip mining, and underground mining. Strip mining, as the name implies, requires massive amounts of soil be removed in order to expose the coal. Such actions leave enormous scars on the earth and require years for reclamation to occur. The eyesores created by mining underground are not as large however, the perils of underground mining have claimed hundreds if not thousands of miners lives in both accidents and diseases brought on by the extreme exposure to coal products. Then comes the extremely expensive task of transporting the coal from the mining sites to locations all around the world. Because of the bulky nature of coal, it requires a massive transportation system, which itself uses other fuels further contributing to the pollution problem. There seems to be little hope of decreasing the size of this operation, since it is entirely dependant upon the physical characteristics of the coal itself. Nuclear energy is the most concentrated source of energy currently available for use. The fuel to drive nuclear energy is also inexpensive, and nuclear energy creates the most compact waste of all the different types of energy. The major steps in the nuclear fuel cycle are as follows: 1. Mining of the ore; the danger of radiation exposures was long ignored however, the advancement of our knowledge of radioactivity has greatly reduced the risks involved with the mining process. 2.Milling; waste accounts for 99% of the resulting in great accumulations of mine tailings that have to be stored somewhere, the removal and storage of tailings still presents a problem. 5.Fuel Fabrication; once converted and enriched, the fuel is formed into ceramic balls and placed inside a tube, thus becoming a fuel rod. 6.Fuel Reprocessing; After the fuel rod is used up, it is placed underwater and stored for up to a year, after which the rod is disassembled and some of the leftover materials are reused in the enrichment phase. 7.Waste Management; Radioactive waste can have half-lives of tens of thousands of years, long-term solutions are needed. As of today waste in a concentrated liquid form is put in temporary depositories, with the hope of someday solidifying the waste so it can be stored for the long-term. From these steps, one can see the basic processes required for nuclear energy to occur. The extreme amounts of tailings present a huge hurdle to overcome, researchers are currently searching for new methods to obtain the ore, which are both less wasteful and cost efficient. However, one large benefit of nuclear energy is the ease of recycling many of the nuclear core wastes. There are no greenhouse or acid rain effects caused by the use of nuclear energy and the process itself has been thoroughly developed and understood by scientists. As with coal nuclear energy also has its drawbacks. First, nuclear plants are very expensive and require large amounts of capital before building can take place. Secondly, although the waste is very compact, the waste is also highly hazardous to the environment. And lastly there is the issue of nuclear meltdown, which is detrimental to life and the environment. This last issue of meltdown or other possible cases of public exposure is the single largest factor limiting further implementation of nuclear power around the world. People assume that nuclear energy is extremely unstable, when it is actually extremely stable. Coal power is much more hazardous than nuclear power, but people seem to be unwilling to accept nuclear energy and continue to use less safe coal energy. The transportation of nuclear energy is extremely safe. â€Å"No activity in the history of technology has as good a safety record and is accomplished with as little risk as the transportation of nuclear material.† Knowing such a fact as this might begin to persuade those who doubt the safety of nuclear energy, and possibly embrace this technology. With this brief look into the environmental crisis that human†s high energy needs have created, it is important for us to find a suitable solution that appeases our energy needs without destroying the environment any more. It is necessary to gauge the benefits against the risks of all of our energy sources, and determine which ones best suit our needs and the needs of the planet. We can no longer be an uneducated public, for the power governing which sources of energy are used ultimately lie in the hands of the public. Fear of what we do not understand is not the way to decide, people need to take the initiative to discover for themselves what is best for them, and more importantly what is best for the environment.

Terra Gatson Essay

They similar because they tend have we as people questioning and have also different perceptions about the world we live in. Hey both were misled as to what the world we live in is and how it operates as a whole. There are also other topics as well that can be pointed to show exactly what else can be depicted about the comparison between them. The Matrix is Greek philosophy which is very interesting to a lot of people. The definition behind is the idea of freeing one's soul or mind as even presented in the Allegory of Cave is a well-known idea attached to Greek philosophy.The difference between them is that The Matrix and The Plat's tend to have reasons that justify and reasons as to why they tend to do what they do. It is something that they come up to make whatever wrong they are doing to give a good reasons as to why they are doing it. Seems like a wrong thing to do, but looking at my life I have ran into a lot of people that make up excuses to cover their behinds so others will be believers of their wrongs. A wrong is a wrong and a right is a right not the other way around.The bible is a great source to find out the truth to a lot so if you want to know if something is true pick up a bible to retrieve some of your information so you will have a better understanding. At the end of the Matrix we were left with a piece to my understanding that had me thinking we were living in a computer based world but looked passed it, but it sometimes have me thinking. The Matrix is really based on Descartes which is about the human race being deceived in many different ways.Many scientist research a lot to prove that we are not living in this or that but it is left to only one person to determine what our lives are and that is the man up above. I have my doubts about a lot but I know God is the reason for everything but would have to say were are not computer based which is my opinion and I'm sticking to it. The world that we are living in today is a test of our faith but the devil will not take the faith that I have in my awesome God because I know it is him who has watched over me for 21 years ND I love him for that.I WOUld have to say for me that the in question three that I don't like either but if I had to decide would say Ignorance is bliss because it's something I tend to say a lot. I don't want to dwell on that topic because the most important one is question and I think it was covered well. The three synopsis were good but its nothing like watching the actual movie to get every fine detail as to why this happened and how it actually occurred, but the synopsis was great to go by because I'm sure everyone doesn't have time to look at three movies in a week.

Nonverbal Communication Paper Essay Example | Topics and Well Written Essays - 1250 words

Nonverbal Communication Paper - Essay Example We use it almost in half of our communications daily subconsciously. We communicate nonverbally when ever we smile, gesture to come in, widen our eyes or clasp our face. We are unaware about it but use it to convey our emotions nonverbally. When speaking to an audience the speaker sends verbal as well as non verbal messages. The eye contact and gestures send messages of their own. â€Å"If the body language opposes with the words you are speaking the entire speech becomes worthless (Toastmasters int’l, 2011, p 3).† There are many biological factors on which the audience judges a person by many means other than the words being spoken. Facial expressions A person can unknowingly express a thousand words by facial expression. A smile or a frown express the extent of delight in the meeting nonverbally. As nonverbal gestures can vary throughout cultures but the smile, frown or a grunt are known to be the same globally. Gestures Intentional gestures such as waving or pointing or using the fingers to point out numbers are an important way to communicate nonverbally. Other gestures can vary according to regions. Paralinguistic This is another way to judge the speaker. The tone, loudness, pitches in the voice separates the actual tone being used otherwise. When the speaker uses loudness to emphasize on something it means enthusiasm and need for acknowledgement while a sullen voice would not be hesitant to point out the lack of interest by the speaker. Posture This apart from the speaker shows a lot about the listener. The body language shows exactly what is going on in the mind of the listeners, crossing the arms and legs would indicate as being in a defensive position while gazing at objects in the room around indicates that the listener has lost interest in the communication and is no longer attentive. Eye contact Maintaining eye contact is a symbol that means the speaker wants to be heard attentively. Blinking too often might send a message of feeling l ost and unsure about the situation. Every region or country has its own language, verbal and nonverbal. It is the traditions and culture that differentiates the nature of nonverbal communication. In America a handshake with a female or a male, means greeting the visitor warmly, while in eastern culture if a man shakes hand with a woman that may refer to harassment. â€Å"An American politician in his visit to a neighboring country once used gestures thinking to make a positive effect but actually emerged enraging the community (Hesselgrave & Culbertson, 1976).† In America people use gestures to convey their messages more than talking out loudly in public or when to pass on secrets. They usually make gestures with their hands and fingers or use facial expressions to communicate nonverbally. It is commonly notices in their films and other events of people using gestures when passing messages and not arousing curiosity of others around them. Also this is considered more appropri ate mode of communication between people who are present in extremely noisy places and are at a distance such as in concerts and clubs or huge gatherings where talking or shouting would seem pointless. â€Å"Sometimes young people have their own special gestures that only they and their friends understand.† (Gestures, n.d.). Some of the gestures might be used to communicate friendly messages while others may also be used

Function of place in Mad Max 2 by Georgre Miller 1981 (film) Movie Review

Function of place in Mad Max 2 by Georgre Miller 1981 (film) - Movie Review Example The cinematography of Mad Max 2 makes very little use of interiors but instead invites the audience to a wide open desert space, reminiscent of the blue skies, red sand and rugged canyons that were common in traditional westerns. The characters in their black leather or white canvas clothing move around this desolate space, and the impression that is given is deliberately edgy and harsh. The sun beats down on the settlers’ camp, and the bikers circle like marauding Indians, and all of the humans appear to be in a frontier between civilization and a deadly wilderness. The way the camera approaches the action is very different from the predictable and safe western style, however. Car chases are filmed with the camera low to the ground, and the vehicles approaching at speed and this draws the audience right into the danger. The main character played by Mel Gibson, is a drifter, neither one of the robbers, nor one of the homesteaders with their homely pigs and chickens. This locat ion does not symbolize the pioneers taming the wilderness, but rather the wilderness has the upper hand and the settlers are very much at its mercy. This film uses location to underline the destructiveness of industrialization and the precariousness of human survivors after an apocalyptic war.

Michelangelo Merisi da Caravaggio The Calling of Saint Mathew Research Paper

Michelangelo Merisi da Caravaggio The Calling of Saint Mathew - Research Paper Example It is understood that a painting is incomplete without knowledge of its background. Further, interpretations of a painting vary between people and with time and it is the contradictory interpretations in paintings that makes the painting interesting and often lend an element of mystery towards it. The painting discussed in this paper is also not without its special context and interpretations. Discussion The painting, The Calling of Saint Mathews is a masterpiece that was commissioned by the church to be hanged within the Contraelli Chapel located inside the Church of San Luigi Dei Francesi. The chapel was meant to be an ode for Saint Mathews and for this Caravaggio was selected when the first choice of the church, Cavalier D’Arpino became busy with the royal patronage. This was probably the biggest church commission that Caravaggio got at that time. Therefore, he put all this time and energy into the creation of this masterpiece along with two others painting, the Martyrdom o f Saint Matthews and The Inspiration of Saint Mathews. The painting till date hangs with other paintings depicting important moments in the life of Saint Mathews. The painting was completed in 1600. We have to understand that this was a time when the church was in power. It had the money to fund biblical paintings. The Calling of Saint Mathews is a painting representing an important biblical sense. The painting takes reference from Luke 5:27-28, which reads: ‘And after that He went out and noticed a tax collector named Levi sitting in the tax booth, and He said to him, ‘Follow me’. And he left everything behind, and got up and began to follow him’ (Benner, 124) The painting, quite like many produced in the same era, is full of religious symbols. The painting, primarily, symbolizes the difference between Christ and Matthews. In this respect, the picture can be divided into two parts: one part showing Christ and Peter while the other depicting Mathews and his companies. Both these parts are in stark contrast with each other. Christ and Peter represent spirituality. They do so through their simple clothing and the fact they do not wear any shoes. The absence of footwear reflects on the fact that these men are down to earth without any love for material objects. Mathews and his companions reflect the worldly life. This is apparent in the way they dress: fashionably in the attire that was trend during the time period when the painting was created. Also the presence of the coins and the preoccupation of some companions with the coins reflect on the worldly life enjoyed by Mathews and his companies (Benner, 129). Another symbol apparent in the painting is the way the painting has been divided into two parts. Here Caravaggio uses his typical style of chiaroscuro where he paints a stark contrast of light and dark in the painting (Cunningham and Reich, 360). Between Christ and Mathews, Caravaggio has painted a dark area and the hand of Christ e xtending towards the dark spot. The light in the picture comes from the side where Christ is standing. This play of light seems to be intentional on the part of the painter as he depicts Christ as a beacon of hope and light for Mathews while taking him away from a life of materialistic love and wastage. Also the dark spot between the two important figures symbolizes the fact that before Christ, people were left in darkness with no way to reach

Service Management - Assignment Example rt charging their clients for the value of the "transformation" which the experience provides, for instance, as education offerings may do if they were capable of participating in the value, which is created through the educated person (Pine and Gilmore 2). This, it is argued in the article, is simply a natural evolution in the value imposed by the business in addition to its inputs. According to the article, even if the idea of the Experience Economy was given birth to in the business field, it has crossed over its frontiers to fields such as tourism, architecture, urban planners, nursing and many other fields in the economy. The article also considers the Experience Economy as the main foundation for client experience management. In the hospitality management academic programs, both in the United States and Europe, Experience Economy is frequently shortened to Exponomy plus is of rising focus (Pine and Gilmore 3). The article consider experience as the fourth economic offering, but one that until recently gone unacknowledged. Experiences have existed ever since, but businesses, their clients, together with economists, lumped them into the service field, as well as such uneventful events such as auto repair, dry cleaning, wholesale distribution together with telephone access. When an individual pays for a service, he or she pays for a set of intangible events done on his or her behalf (Pine and Gilmore 3). However, when they pay for experience, they pay to spend their time enjoying or benefiting from a string of memorable activities, which a business stages to engage them in a more personal way (Pine and Gilmore 3). As a customer, I have had two types of experiences in the economic world, good and bad, which have made me loyal to some businesses and never to return to others after experiencing what they had to offer. I have been loyal to the person who sells me Blue Ray DvDs because of the experience I get when visiting his store. Every time I visit his store, he
