...The threat of nuclear weapons maintains world peace. Nuclear power provides cheap and clean energy. The benefit of nuclear technology far outweight the disadvantages. To what extent do you agree or disagree? In our world today, nuclear technology has become one of the top publics topic being discussed in the mass media. It has become part of life in many nations. However there are some question such as : “ If it is advancing our world or destroy it?” Besides the advantages, it aslo has drawbacks and it depends on the people who use to determine it is a force for good or evil. We can clearly see the benefits nuclear power brings to us. While the cost of fuel is increasing everday and other energy sources such as coal and oil are seemingly being used up, nuclear power is a good choice. It is quicker, cleaner and cheaper to produce. Nuclear power does not pollute the air and enviroment as much as coal and oil plants do. Nuclear power plants could still produce electricity after coal and oil become scarce. They need less fuel than ones that burn fossil fuel. Presently, nuclear energy provides for approximately 16% of the world’s electricity. Never the less, it aslo has disadvantages. The effect of radiation causes heath problems, can be very dangerous to living things. Hamful radiation has had negative affects on people and animals that have included deformation, disease and even death. Moreover, nuclear energy is also non-renewable source of energy. The use of non-renewable energy...

...Can nuclear energy be a main alternative energy socio-economically rather than other alternative energy to decrease global warming? Introduction Nowadays it seems that most people recognize about the severity of global warming. Houghton (1997) believes that increasing alternative energy rather than using fossil fuels is very important to decrease global warming. Therefore, I chose this topic: Can nuclear energy be a main alternative energy socio-economically rather than other alternative energy to decrease global warming? This assignment will identify why serious global warming started and discuss about nuclear energy as an alternative energy. Finally, it will be examined how people think about nuclear energy used to decrease global warming. Global warming by human activity According to Houghton (1997), since Industrial Revolution fossil fuels such as coal, oil and gas are being burnt worldwide rapidly and a lot of carbon dioxide from burning the fossil fuels is promoting global warming. Giddens (1998) stated that many scientists believe the main cause of global warming is carbon dioxide increased. Carbon dioxide which is one of green house gas such as methane, water vapour and nitrous oxide absorbs heat and then re-emit on the earth. So, with carbon dioxide increase, temperature rises on the earth (Carter, 2010) Wyatt (2008) stated that “Industrial revolution stimulated a major increase in production and mass consumption. The ancient sources of power-human...

...Introduction Zirconium metallurgy has been developed essentially due to the nuclear industry. They are used as a structural material in nuclear industry mainly because of good corrosion resistance in water at high temperatures, resistance to radiation damage, optimum mechanical properties and low cross-sectional absorption of thermal neutrons. Four elements satisfy the last two conditions but Zirconium is the only sufficient choice for core components of nuclear reactors. The other elements such as Beryllium (Brittle and chemically toxic), Magnesium (chemically reactive and cannot be used in water cooled reactors), Aluminum (low melting temperature hence only used in research reactors) are not chosen. Important Characteristics of Zirconium-Nuclear Structural Material 1) Low thermal neutron absorption cross section (0.185 barns), 2) Allotropy, the high temperature body centered cubic (β) phase transforming into the hexagonal close packed phase (α) at 1135 K, 3) Anisotropic thermal and mechanical properties leading to unequal thermal expansions along different crystallographic directions and formation of strong crystallographic texture during mechanical working 4) Hexagonal close packed structure of the a phase with a c/a ratio of 1.593, which is less than ideal, making the prismatic slip on {I 0 1 O} planes most predominant, 5) High reactivity with oxygen, nitrogen and carbon and high solubility of these interstitial elements in the α phase, necessitating special care...

...In addition, technology to prevent acid corrosion is already fully developed. However, colonisation on Mars would require shields whose components have yet to be determined by scientists, as polyethylene and carbon composite shielding has shown to be ineffective against radiation concerning human life; aluminum shielding does provide some risk-reduction, however not enough to protect humans from the grim effects of radiation. Our knowledge of space radiobiology would have to significantly improve before shields could be made to protect humans on Mars’ surface. In addition, scientist would need to determine the costs and risk of constructing underground sanctuaries for humans, as this is the only way to properly protect them from the intense levels of radiation...

...Since time immemorial, mankind has created objects and methods to make their lives easier. We commonly refer to these innovations as technology. From the first wooden spear created by the caveman to the latest augmented reality of today’s Silicon Valley, these innovations have been technology. Since technology has been adopted, there have been naysayers that have always spouted the same lines of “This technology is going to ruin us” and “This technology is evil”. In this essay, we will show the duality of technology by the destructive nature of it, the beneficial nature, and the choices mankind makes when it puts these technologies into practice. In 1945, at 5:29:45 a.m., the Manhattan Project came to an explosive end as the first atom bomb...

...The United States nuclear energy sector stands at a crossroads. We have the opportunity to resume construction of new nuclear plants, revive a once-vital nuclear supply chain, explore and deploy new technologies and reclaim our place as a global leader in the production of nuclear energy. If we do, this nation will reap the benefits: abundant, emissions-free baseload electric power and process heat for industry and substantial economic growth. Additionally, the United States will reestablish its leadership in global nuclear energy and nonproliferation policy, which is directly related to the credibility and vitality of our own nuclear industry. But the rebirth of the American nuclear industry is not guaranteed. The lead times are long, and the costs of building new plants and developing new technologies are high. The various private sector firms that will ultimately decide the future of nuclear energy—through what they design, finance, purchase and build—all must consider the complex economics of such huge investments. This is made all the more difficult in the face of substantial uncertainties about broad government policies, specific regulatory actions and the price and availability of other energy sources. Indeed, the future of nuclear energy is dependent upon an interwoven set of decisions made by both the public and private sectors. On the one hand, private industry cannot act without clear, stable policies and active involvement from the...

...How Technology has Changed Our Lives Technology has allowed people to connect with other people at ease, and has made life and simple tasks so much easier. From computers to phones, the world today allows people to communicate with anybody whenever. From listening to music, to surfing the internet, technology has made everyday life more convenient. Texting on phones and connecting on social networking sites requires very little effort. Technology has changed all of our lives and made it much easier to function throughout the day because of it. It is far different from how it was 10 years ago, everything is so much faster and smaller. At one time, every adult had one of those Nokia phones that could withstand a nuclear bomb. With all of the new technology that was coming on to the market, it was difficult to see what else the technology world could do to help improve lives. Yet, things like the iPhone have been created, which has completely evolved today’s society into a cyber-society. People live through phones, but it is not the most important technological creation. In the last couple of years, technology has done things that people could have never imagined in the 1990’s, even at the turn of the century, more people used to do things by hand and face to face. Now, computers are everywhere, even in your local McDonald’s, with internet that works at incredible speeds. Phones answer questions, and also do many other tasks that people never thought possible. Now there is...

Now we can enjoy every second of our life through them. Technology have totally changed the field of entertainment. Now we can entertain ourselves through computers, Games, TV and so on. Electric light, Air conditioner, fan, and all the electronic gadgets are all gift of science. We can enjoy cold coffee, mango shakes, cold drinks during summer season through refreigeratos. All these things are possible through science and technology. Today travelling have become very fast. We can travel a long distance in minutes through aeroplanes. All this is possible through science. The railway is the another way of comfort travelling. Cars, buses, scooters are other means of travelling which we use day and night. These things made our life trouble free. It is all the wonder of science. Modern world is more and more dependent on them. It is said that "Science is a good and useful servant but it is a bad destructive master." I am saying this thing because today we are misusing it. Today atomic energy is used for war and fight purpose. Why we are not using it for peaceful purposes? Our aim should be constructive not destructive. Today we are using science...

...1st Draft Dependence from technologies Humanity or Mankind has evolved from the essence that separates humans from beasts: the ability to use the mind for reason. Reason is the ability to analyze, create, deduce, and formulate. It is reason that enables human beings to strive to invent; it is through invention that mankind has developed society and created a better world. When we speak about the relationships between technology and humanity, it is evident that we have to deal with the interrelations between some very complex phenomena: technology, science, society or systems of societies, and systems of rights of a universal nature. The discovery and development of a large number of powerful energy sources-coal, petroleum, electricity etc. have enabled humanity to conquer the barriers of nature. All this has facilitates the growth of fast modes of transport, which in turn has transformed the world into a global village. Newer and newer advances are happening by the day. Technological change is in large part responsible for many of the secular trends in such basic parameters of the human condition as the size of the world population, life expectancy, education levels, material standards of living, and the nature of work, communication, health care, war, and the effects of human activities on the natural environment. Technological development has provided human history with a kind of directionality. 1) Without the needed technology a lot of people would struggle with their...

...out the poor and disadvantaged communities with degraded public transport that leads to social polarization. As these opposite forces of urban sprawl loomed large on a global scale, authorities placed environmental and social issues as major items on the public agenda and underlined the alarm on the gravity of such global crisis. Subsequently, the conference of business groups contends that technological solutions are the most economic and effective way to address problems and advocates striving for alternative clean energy. However, whether technological resolutions can solute the problems radically awaited further discussion. In some degree, technology does indeed make a difference on relieving ecological pressure, but it should not be underestimated that technology carries the potential to threaten environment. Technology advocates assert that exploring alternative energy via...

...Duc Vo Heidi Kozlowski Eng1B 9/24/2013 THERE WILL COME SOFT RAINS “August 2026: There will come soft rains” is a short story by Ray Bradbury. The story is about a house equipped with extensive machinery to facilitate the delivery of any needs and performance of any activities that the owners could need. The story is set in the year of 2026 where advanced technological development conquers Earth. Therefore, the house is able to operate daily activities and maintain itself without assistance from other parties. The story begins in the early morning of 4th August 2026. It goes on to describe the different activities that usually go on in the house from morning to evening. There is clear specification of the duties that the house undertakes during this period. These activities include waking the occupants, making breakfast, cleaning and maintaining both the house and the compound among other duties. It is however important to note that the occupants of the house are not present throughout the story. It is also implied that these occupants had not been around for a long time and would not be coming back anytime soon. On the evening of 4th August 2026, the house is accidentally set on fire and burns to the ground by the next morning. The different machines try to clean up the mess but they are defeated by the raging fire which eventually leads to the destruction of everything inside the house, except for one wall. The setting of the story is distinctly...

...Layne Hazam English 101 Prof. Anderson Aug 7, 2010 Attack of the Clones I recall sitting around the dinner table with my family as a teenager and engaging in riveting debates about the numerous possibilities cloning had for our world. In recent years, due to sports injuries and other battle wounds, these possibilities have become increasingly personal for me, even as the technology and the debates have rapidly advanced. It seems that since the discovery of fire humanity has attempted to imitate and manipulate phenomena that nature has had billions of years to develop and perfect. Cloning is a perfect example of such attempts. In nature, cloning is the process by which genetically identical organisms are produced by way of asexual reproduction. With some success, scientists have been working on ways to reproduce this phenomenon through biotechnology, in a laboratory setting. In biotechnology, cloning refers to the process used to create copies of DNA, cells, or entire organisms. Each of these forms of cloning will be described in this paper, which will then explore the issues surrounding cloning from biological, technological and public health standpoints. Molecular cloning, or DNA cloning, is the process of making multiple copies of an isolated sequence of DNA fragments (Strachan & Read, 1999). This form of cloning is most often used in biological research, but is also used in more practical applications such as genetic profiling and protein production. In practice, techniques such as this are often used ...

Business forms and use various means such as web, email, text messages in order to manage, connect, communicate and trade in modern form. II. Body The development of human race always bases on knowledge and capable of creative. On last historical period, people mostly do by instinct, with little knowledge, not enough to be creative. Switch to the era of agricultural civilization, people began to have created innovative tools such as farming (plow, plant hoes, and water). However, it took from 4000 to 5000 years after, human began to have real knowledge, be aware to the objective law and entered a new era of the industrial era, the era of the great technical innovations. Due to grasp the objective law, science thrives, especially in the late 19th to early 20th century. More new branches appear as quantum research, nuclear, aerospace, ocean … However, it slowly moves since the 2nd world war, the scientific and technologic achievements were used in military purposes. After the war ends, the world has condition to change scientific achievements into technology. In 80s and 90s of 19th century, technology was developed with remarkable speed.

...addition to these two, other factors such as environment also compose progress. The first pillar of progress is economic development. In our society where materialistic values have continued to dominate, economic growth has often been understood to be synonymous with progress. Ex : Over a few decades, our world’s outstanding economic performance has lifted many people in the developing world out of poverty and has enabled countries such as China or India to experience fast economic growth. Another dimension of material progress is development in science and technology. Our society has achieved great development in science and technology that have made our lives better and more convenient. It goes without saying that the computer revolution has changed all our lives. The clou dis one of the latest and the greatest innovations in computer technology. In addition, even justice has improved thanks to new technology exposing false convictions and identifying true criminals.
