Desenvolvimento de um novo conceito para o índice de Wobbe

The increasing demand for alternative fuels lead to the search for solutions to use these fuels in old equipments and bring for new equipments the necessity of alternative fuels based burners. As a solution for these necessity the Gas Interchangeability`s studies came in evidence, because it studies the possibility of changing one fuel for another without changing the initial condition. In integrated industries, as most of steel industries, there is a link between process, the byproducts of one process are used as fuel for other process. There are new conditions for the equipments, that will be developed for these fuels, but even in these industries there will be situations which the byproduct won`t be available, and the process cannot stop. Using the gas interchangeability`s concepts is possible to work with security in both cases. Using alternative fuels in fossil fuel based burners and having a back-up solution for new technology burner. But using these new solutions were verified that there are some cases which the interchangeability`s methods does not work with satisfactory results, and for this reason, this study came to develop a new concept for the Method of Wobbe Index to evaluate the possibility to increase the range of the satisfactory results

Desenvolvimento de metodologia para a obtenção da cubicagem de madeira em toras empilhadas através de imagens digitais

Obtaining accurate estimates of the volume of stacked wood is important in view of the increasing value of wood as raw material. Therefore, the forest companies have become increasingly concerned about the methods currently used to convert cubic meters for stereo. In this context, emerged the need of optimizing the measurement process and accuracy of the volume of stacked wood. For this, companies have been testing methods with greater efficiency, speed and low operating cost. Existing methods made through approximate equations, and also by determining the conversion factor, called the stacking factor (Fe), are questioned, due to errors and inaccuracies. The use of digital photographs is an alternative method that would minimize operator intervention, allowing greater control and speed the process, thus eliminating part of the imprecision of the traditional method. The use of the method is viable, due to present an error of about 10% while traditional methods showed an error of 17%

A institucionalização da agricultura familiar no mercosul

The Mercosul project, signed in 1991, represents the union of a political project, characterized by a democratic agreement among its members, with an economical project characterized by the trade liberalization among its regional members and among these with the global economy. So, it was constituted, with the aim to expand the national trades by the integration, to increase the economic development process with social justice. However, the Mercosul follows the historical trajectory of Latin America integration, characterized by models that aimed the economical development from the strengthening of the industry. According to that, the Mercosul politics are priority for economic issues, focused in the industrialization and trade relations, giving less priority to the social demands. In opposition to such ideas, in 2004 was created the Especialized Meeting about Family Farm (Reunião Especializada sobre Agricultura Familiar - REAF) in the Mercosul, that aim to strengthen the public policies of the sector, to promote the commercialization of the family farm products in the region. So, the family farm, a sector historically marginalized from the integration projects, it is institutionalized in the Mercosul. In that way, the aim of this research is to discuss the reasons that leaded to the family farm institutionalization, and also to analyze the advances and problems of the Especialized Meeting about Family Farm

Desenvolvimento de vasos digestores de amostra para microondas doméstico

The application of microwave radiation on the sample preparation has been expanding increasingly in areas involving decomposition by wet and dry roads, fusion, extraction, acceleration of chemical reactions, for example. Currently, the use of microwave ovens for analytical purposes are recognized for having excellent performance for organic and inorganic samples. In the international market there are several kinds of microwaves oven which adapt the varied purposes, however yet with elevated prices which incapacitate your use as routine equipment in laboratory. Thus, many researchers have been choosing for developing own projects of microwaves oven production or to use domestic oven for the laboratory, with or without adaptations. For the evaluation of the proposed method was used in the Kjeldahl methodology for determining total nitrogen in samples of crude protein, using a domestic microwave oven and a digester pot made up in TeflonTM and distillation by steam. Were made to adapt and characterization of a domestic microwave oven, the confeccion vessel digester and the metal support for the vessel. The accuracy of the proposed method was confirmed by comparison of two methods, the standard method for conventional heating and by the proposed method, with heating by microwave radiation through the calculated values of relative standard deviation analysis

Impactos e características nos projetos hidrelétricos Sul-americanos: o caso de Inambari no Peru, o investimento brasileiro e a lei de consulta prévia, 2006-2011

Esta pesquisa trata de um grande projeto hidrelétrico, Inambari, que estava se transformando em realidade como parte de acordos entre o governo do Brasil no segúndo período de Lula (2006-2010) e do governo peruano de Alan Garcia – AG (2006-2011). Inambari é um dos mais recentes projetos hidrelétricos peruanos feitos para exportar ao Brasil. Mas, apesar de formar parte de um acordo entre esses países, por agora está detido devido a protestos e mobilizações da população dos territ´porios de Inambari contra a política hegemônica de AG. Analogamente ao caso da estrada Interoceãnica Sul, a construção e operação da Usina Inambari pode ser entendida como um caso emblemático no cenário Latino Americano atual. Esta não seria apenas o maior projeto hidrelétrico da amazônia peruana, custando aproximadamente 4 bilhões de dolares e prometendo um potencial de geração de energia elétrica de cerca de 2.200 MW para exportar ao Brasil por ano, mas também concretizaria o vínculo energético estratégico entre estes dois países através de um complexo de usinas e linhas de transmissão interconectados. Para sua concretização se conta com o amparo financeiro e legislativo dos dois governos e suas instituições de fomento, além de instituições de internacionais de investimento (como o BID e o BM) e do capital internacional (este útlimo proveniente principalmente de empreiteiras brasileiras beneficiárias do modelo de concessões federais). Aqui se estudam os potenciais impactos na economia amazônica do modelo vigente de exploração de recursos naturais hídricos amazônicos através do caso INAMBARI. A conclusão aponta que inexistência de participação popular como o maior entrave ao desenvolvimento amazônico e tenta explicar a novaconfiguração dos movimentos sociais que buscam voz para os povos da Amazônia bem como o pioneirismo peruano em relação a lei de consulta prévia
