...Fusion Power - The Cons While fusion power may be the answer to our energy prayers, it is not currently a viable option. While there are no obvious drawbacks to the use of fusion power, we are years if not decades away from harnessing this power. Scientists must achieve the necessary temperatures, which has been done; demonstrate sustained reactions where substantial amounts of energy are produced, and complete operation of a demonstration fusion power plant. To better understand what needs to be done, one needs to understand the fusion process. To produce net power the fusion reactions of a gaseous deuterium-tritium fuel must be heated to about 100 million degrees Celsius (more than six times hotter than the interior of the sun). Since nuclei normally repel one another because they carry positive charges, their movement will coincide with their temperature - i.e. the higher the temperature, the faster they move. At a faster speed, they overcome the force of repulsion of the positive charges and fuse. These collisions release energy. To date, scientists have attained temperatures as high as 510 million degrees to create these collisions. | | The problem in producing fusion energy is in developing a device that can heat the above fuel to a high enough temperature and then confine it for a length of time that will result in more energy being released through the fusion reactions than it took to actually heat the nuclei. Nature lends a hand...

...Nuclear Fusion How does nuclear fusion work? There is fusion on the sun. Fusion only works one way. Fusion also happens on earth. Chernobyl is a bad example of nuclear explosion. One nuclear bomb can destroy an area for thousands of years. Taylor Wilson is working to help make nuclear power safer. There are many different places that it can occur, but only one way that it can happen, and almost everything you are doing is powered through fusion. Fusion occurs on the sun. Believe it or not, the sun contains 99.8% of all mass in the universe. In all of that the sun is 75% hydrogen and 25% helium which helps produce fusion. Every second the sun converts 500 million metric tons of hydrogen to helium. The type of fusion powered by the sun also...

...nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission. Cost and availability of fuel is a considerable factor when dealing with nuclear power. Fission requires an element that can be easily split in a particle accelerator, such as uranium or plutonium. Fusion, on the other hand, uses isotopes of hydrogen atoms, specifically deuterium and tritium, that can be obtained from ordinary water. Uranium ores occur naturally in many parts of the world but must go through a costly purification process before used as fuel. The unprocessed ore contains approximately 99.3% uranium-238, a non-fissionable isotope of uranium, and only about 0.7% of U-235 required for fission. One hydrogen atom out of 6700 appears as deuterium, a naturally occurring isotope of hydrogen with an extra neutron, and can easily be separated from the rest. Uranium-235 is a non-renewable resource that will eventually run out, much like the fossil fuels. The abundance of deuterium and lithium provide a virtually unlimited supply of fuel for nuclear fusion. Therefore, nuclear fusion seems to be the better choice. Second, the potential amount of energy produced by fusion can greatly outweigh the fission...

...Alecia Rae Atiyeh Winter 2011 Nuclear Fusion Vs Fission At the speed we are using up fossil fuels, nuclear energy is looking more and more like a possible replacement. Nuclear energy is created in two ways, through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission due to the cost and overall availability of the required isotopes, the higher energy output, and the low levels of residual waste. The cost and availability of fuel is a considerable factor when dealing with nuclear power. Fission requires an element that can be easily split in a particle accelerator, such as uranium or plutonium. Fusion, on the other hand, uses isotopes of hydrogen atoms, specifically deuterium and tritium, which can be found in all water. Uranium ores are found naturally throughout the world but must go through an expensive purification procedure before used as fuel. The unprocessed ore contains approximately 99.3% uranium-238, a non-fissionable isotope of uranium, and only about 0.7% of U-235 required for fission. One hydrogen atom out of 6700 appears as deuterium, a naturally occurring isotope of hydrogen with an extra neutron, and can easily be separated from the rest. Uranium-235...

...Pros for Workday vs Fusion: * Better Marketing and use of customer references than Oracle * Better User Interface than Fusion * First Mover advantage in Cloud HCM and the experience that brings to SaaS implementations * More advanced & mature smartphone and tablet apps (Fusion Tap notwithstanding) * Pure, single version of software in cloud; faster and more regular updates that are supposedly seamless for end user Cons for Workday vs Fusion * Very US-Centric; something like 90% of their customers are US Based I think. No UK Payroll here folks (they provide a partner integration via Northgate Arinso). * HCM Point solution; have to partner with other vendors for other functions, like Salesforce for CRM. Caveat that they do have a Finance system, but only 10% uptake amongst their customers. Second caveat is that some customers prefer stitching together 'best of breeds'. * Still have big HCM gaps like Recruitment and Training (expect these to be filled though) * Don't have the Global salesforce that Oracle / SAP enjoy; I think they'll find it tougher to outsell Oracle in strong non-US Oracle markets like UK, Gulf and Australia. * No alternative to Cloud. If 65% of customers want SaaS, that means 35% don't want SaaS (although I suspect the ratio is more like 90%/10% in practice!). Pros for Fusion vs Workday * Integrated Suite, not just HCM (echoing Richard's comments above) * Global salesforce and product direction: non-US localizations available...

...Fusion Bonded Epoxy Coating Engineers and Researchers have found that fusion bonded epoxy coating is the practical and scientific way for protecting steel reinforcement against corrosion Applying an epoxy coating to steel rebar prevents the chlorides from reaching the steel surface. And since the material is applied to the rebar at a mill away from the job site, it is not weather dependent and will not cause construction delays Cracks in the concrete, allowing penetration of chloride bearing waters, is not a factor because the protection is applied on the bar surface where the problem is usually observed. The most effective form of epoxy coating is the fusion bonded method. This allows the coating to achieve adhesion as the result of the heat-catalyzed reaction. An epoxy coating is formed by combining an epoxy resin with the appropriate curing agents, filters, pigments, catalyst and leveling and flow control agents to achieve the desired characteristics It is applied from an electrostatic charged powder state to a pre-heated rebar. The powder when comes in contact with the hot bar, it melts, gets and cures to a well adhered, continuous corrosion resistant coating. The first fusion bonded epoxy coating designed specifically for reinforcing steel was put in the market in 1976. Since then, continuous research, design and testing have taken place which have enhanced and confirmed the effectiveness of fusion bonded epoxy coated rebar [FBECR] in preventing steel corrosion...

...The world desperately needs a new hero to prevent this dystopia. One unknown hero, nuclear fusion, offers a wholesome solution to all of the problems associated with the energy crisis. Fusion power will become an essential component of the industry and lead in energy production because of the following reasons. Firstly, fusion power brings new levels of efficiency never before seen that will fulfill society's energy needs. Beyond potent energy production, nuclear fusion introduces a productive approach to environmentalism and can further alleviate the effects of the global warming. And to guarantee this conflict will never occur again, fusion power’s sustainability is desperately needed for the future's energy sector. But even when nuclear fusion has great expectations, there are some gaps to be filled due to its incomplete research. Factions within the energy sector like environmentalists and the fossil fuel industry realize fusion power’s weaknesses and have strong reasons for opposition against nuclear fusion, but they will be refuted and deemed insignificant in comparison to fusion power’s abilities. With these foundations for energy success, fusion power should become the centerpiece of the energy...

...Prime Minister Abe strongly appealed to the global media his intention towards reforming Japans current economy and to be released from the long lasting recession that has been tormented the lives of the citizens. In the OECD Ministerial Council Meeting that was held on May 6th, he explained the source of Japans hardship lays within the 20years of deflation. This long lasting deflation has begun since the latter half of the 1990s. Inflation expectations fell, resulting a negative output gap and other factors such as a decline in import prices and a rise in interest rates occurred since then until now. The definite cause for the continuation of deflation is that consumers rejected to pour money in to the economy, saving what little money they had. In order to encourage citizens to put more money in to the market, governments took countermeasures such as handing out a portion of money to each and every family, however this policy ended up being useless. Staring from April, Abe launched one of his “three arrow” policy and raised the consumption tax from 5% to 8% and will eventually rise to a 10% tax rate. Also, there is even a theory that mentions the decrease in the number of children is the direct cause of deflation. Abe wishes to build a new economic order with the EU and at the same time promotes political measures to eliminate tariffs between countries for free trade. He states that by executing free trade by setting up a rule that is fair for all states, we can create a vigorous...

...Diario de un boricua que se mudó al norte 12 de agosto- Hoy me mudé a mi nueva casa en el estado de Pensilvania. ¡Qué paz! Todo es tan bonito aquí. Las montañas son majestuosas. Casi no puedo esperar a verlas cubiertas de nieve. ¡Qué bueno haber dejado atrás el calor, la humedad, el tráfico, el ruido y el vacilón de Puerto Rico. ¡Esto si es vida! 14 de octubre- Pensilvania es el lugar más bonito que he visto en mi vida. Las hojas han pasado por todos los tonos de color entre amarillo y rojo. Que bueno es poder disfrutar de las cuatro estaciones del año. Salí a pasear por los bosques y por primera vez vi un ciervo. ¡Qué animal tan estilizado! Es sin lugar a dudas, uno de los animales más vistosos que he visto en mi vida. Con ese porte real, luce sus cuernos como una corona ceñida en una frente siempre erguida, dejando saber que él es el indiscutible rey del bosque. Esto tiene que ser el paraíso. ¡Esto si es vida! 11 de noviembre- Pronto comenzará la temporada de caza de ciervos. No puedo imaginarme que alguien le quiera hacer daño a esas criaturas de Dios. Ya llega el invierno y nevará pronto. ¡Esto si es vida! 2 de diciembre- Anoche nevó. ¡Qué alegría! Me desperté y me encontré que todo estaba cubierto de una capa blanca. Parecía una postal, una película. Salí a quitar la nieve de los escalones, a palear la entrada. Me restregué en la nieve y después tuve una pelea de bolas de nieve con los vecinos (yo gané). La niveladora me volvió a ensuciar la entrada. Pero bueno, que...

...Fusion Centers: A Step In The Right Direction The formation of fusion centers is a step in the right direction to countering terrorist threats. By working efficiently and appropriately, information leading to arrests can be shared across county lines, state lines, and all around the world in a timely manner. Fusion centers can make law enforcement agencies more competent and effective in stopping crimes (to include terrorist attacks) before they take place. As long as the centers follow the laws they are governed by, they will remain ethical and can be a helpful addition in protecting the United States. Fusion centers in the United States perform a valuable role in countering terrorist threats, their positive influence far outweighs any negative actions they have conducted, and continue to provide an invaluable service to US law enforcement. Fusion is the integration and analysis of large amounts of information and intelligence for actionable policy ends (1). According to CongressionalResearch.com, “Fusing foreign intelligence with a wide spectrum of domestic information is the stated primary purpose of fusion centers” (2). Fusion centers, if managed properly, can be a valuable tool in not just countering terrorist threats but also in helping tribal, local, state, and federal law enforcement in stopping criminal activity as well as mitigating the after effects of natural disasters. Fusion centers allow for better communication and encourage the sharing of intelligence...

...Nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus. The source of all the energy so generously radiated by the Sun does two things: it converts hydrogen into helium and it converts mass to energy.Sunspots are small areas that appear darker than their surrounding solar surface. Sunspot areas have strong magnetic field. Occasionally the strong magnetic field in a sunspot is overly twisted and decides to fire up like 'fire works'. Those 'fire works' are solar flares and they are above sunspots. Sunspots last for a bit shorter than a day to several days. Flares are much shorter and last for a few seconds to a few hours. Sunspots are temporary, relatively darker and relatively cooler spots in the sun's photosphere. They are typically of the size of an earth. A solar flare is a sudden, tremendous, explosive outburst of...
