The End of Course Work this aims, the hydrological cycle of water on our planet, and explain about its importance in the lives of living beings, finally, carry out a detailed analysis regarding the financial feasibility of implementing a system Shauer sustainable in the condominium, the first being the pickup of river water, which will use a reservoir for capitation and filtering, a reservoir for water storage filtered and pumps that will redirects it to outside faucets and toilets use in residences

O clima em sua regulamentação político-econômica: o acordo de Copenhague - COP 15

We know that the Earth goes through natural cycles that influence its climate and the development of their societies. In recent decades, climate changes and nature began to call world attention to the unbridled exploitation that was carried by the current economic system, causing unrest among scientific, social, political and economic world. The theory that man causes a warming in global temperatures by the release of greenhouse gases made the headlines of major newspapers in the world. From there, it was only a matter of time before environmental concerns became ownership of capital by its excessive appropriation. The fear of nuclear threat by the bombs of Hiroshima and Nagasaki left in fanfare the world, which together with the devastating impact of the exploitation of man and nature gave birth to the Environmental Revolution, a way of trying to change the development patterns of the time and behavior of the population. However, based on the historical form of capitalist domination, this was another measure that was apossada the economic system being transformed into economic value and political exchange. The origin of the conventions, meetings, conferences, parliaments set up to discuss environmental issues, eventually became forums of political and economic talks focused on environmental governance, valuing an asset that is public and everyone. Environmental and climate issue now has a value, thus turning the agenda on the agenda of the United Nations (UN) for its political and economic regulation in the form of global agreement. Given the need for understanding the climate issue, was born the Conference of the Parties (COPs), a regulatory body for climate negotiations, surrounded interests, complexities, conflicts and disagreements between the parties countries, which becomes clear when we analyze their agreements...

APR e FMEA em trocador de calor de bomba

The modernization of the world made the speed, accuracy and reliability of all existing processes become increasingly necessary. For this evolution to occur every day, the evolution of the equipment was strategic, but not as much as needed. It is necessary for such equipment to ensure its function and, in case of failure, an early diagnosis to prevent loss. Therefore the evolution of maintainability and reliability in equipment is also paramount. Thus, the growth of forms of maintenance was driven by this scenario, forming maintenance philosophies. Among many, there is the RCM, which have its focus on the identification, parameters development and performance preview. One of those methodologies from this idea is the FMEA, process that has been studied and implemented this work, aiming the anticipation of failure modes and guidance for the use of a heat exchanger and a pump. This implementation has the aid of another process of RCM, the PHA, which was also shown and implemented, these results being used to start the FMEA process. The results show the activities with the highest chance of failure, presenting also the measures to be taken to avoid or minimize them. It is shown, in this paper, concern with the valves because they maintain control and system security, and its flaws related to accidents with possible danger to people and the whole system, emphasizing the priority of action
