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

A distorção do conceito de economia no jornal Folha de São Paulo

The work aims to analyse the concept of economics as the science of scarcity is distorced in the newspaper Folha de Sao Paulo. Neoclassical economists characterize the economy as the science that is concerned with the welfare of the people, satisfying their needs. However, the economy in the newspapers of the mainstream media appears in contexts where only the profit of companies and businesses are addressed, leaving aside the problem of economic inequality, unemployment, working conditions and other issues that are also part of economy, but they are hardly concerns of journalists. In this work, the object of study was the notebook Market and content analysis followed the criteria of Bardin (1977). Ten words were chosen in the category science of scarcity and ten words were chosen in the category science of abundance. From these categories, a careful reading was done, counting how many times each word appeared in the newspaper. Also paid attention to the words that appeared and contexts in which they fell journalistic genre. In a second step, interviews were conducted with journalists from economics to know what they mean by the economy and what the guidelines are more common. Data collection and interviews contributed to the interpretation and confirmation on whether or not the distortion of the concept of economy and how it happens

Atualização do conceito de qualidade na construção civil

The quality control is of great importance for the development of any organization, mainly for providing an assurance of delivering high quality services and goods for the consumers. Quality can be defined by the word „change‟, for the company which intends to implement a quality control system must be open to changes. This can be noticed from the JURAN concept (1992 In SILVEIRA ET AL., 2002): “Quality is to fit for usage”, i.e., depending on the goal, the situation and the consumer, quality is seen in different ways, since each one has different wishes and opinions. Taking in to account the availability of means such as norms, theories and tools, that contribute for an efficient quality management system, this discrepancy of opinions and the lack of objectivity of this concept can be solved, since through the analyzes of these means one can set quality standards, i.e., market references which fulfill both consumers and builders demands. Thus, the quality concept ceases to be something so abstract, non-measurable, to become a more objective concept. Finally, the goal of this work is to analyze the quality concept through bibliographic studies and possible consumers‟ enquires, aiming at the building industry, and show how the quality, often taken as something abstract, can be a measurable and objective concept, that benefits both the consumer as well as the enterprise of this branch

A influência da mídia no conceito de corpo

Esta monografia teve como objetivo demonstrar as diferentes concepções culturais do corpo ao longo de diferentes épocas e como os padrões sociais estabelecidos influenciam diretamente a maneira de visualizar esse corpo. Os meios de comunicação do século XX se desenvolveram de maneira vertiginosa, ficando mais acessíveis a população e aumentando a influência sobre esta. A geração fitness do início da década de 1980, que tinha como objetivo incentivar a prática de exercícios físicos para a população, acabou sendo amplamente divulgada pela mídia e exercendo grande influencia na sociedade. O padrão de corpo, bastante divulgado na sociedade atual, consiste em mulheres jovens, magras, e com o corpo bem delineado e homens fortes e musculosos. O corpo ficou banalizado. A mídia impõem o corpo ideal para toda a sociedade utilizando de inúmeras propagandas, com pessoas famosas e bem sucedidas relacionando muitas vezes o sucesso delas com o seu corpo. Várias pessoas acabam utilizando métodos nada saudáveis para a obtenção desse corpo ideal. Porém, isso pode causar inúmeras complicações de saúde e em alguns casos, a morte. O corpo perfeito, que deveria significar saúde, está virando sinônimo de doença e obsessão.

Avaliação da auto-suficiência energética em reatores anaeróbios aplicados ao tratamento de resíduos da indústria de produção do etanol

Ethanol, the main automotive biofuel, has its production based on the fermentation of sugars found in biological materials and on the distillation of the alcoholic media formed during the fermentative process. Stillage is the main residue from ethanol production, containing a high organic loading in addition to acidic and corrosive characteristics. Considering the available technologies to treat stillage, we highlight anaerobic digestion, which allows the reduction of the impacts associated to pollutants loading of this effluent and the generation of energy from the methane gas produced in the process. Based on the high treatment efficiency usually associated to the anaerobic process, this work aimed to assess whether anaerobic systems applied to the treatment of stillage are energetically self-sufficient. First we evaluated the energy recovery capacity in an anaerobic reactor applied to the treatment of stillage resulting from corn-to-ethanol processing. The results indicated the great influence that a correct selection of electrical equipment and their respective operating periods have on the net energy balance of the anaerobic treatment. The high energy consumption of the heater would not allow the system to achieve a positive net energy balance – the maximum energy recovery would reach only 0.68% of the consumption. However, the replacement of the mixture equipment would result in energy gains ranging from 8.5 to 967.9% of the consumption. In this work we also assessed the efficiency of methane yields for a few studies and the correlation between some parameters of the anaerobic process. With respect to the methane yield, we noted that mesophilic systems tend to be more advantageous than the thermophilic ones (efficiency of 76.45 ± 22.51% vs. 69.40 ± 30.36%). Considering the study...

Avaliação da auto-suficiência energética de reatores anaeróbios no tratamento de esgoto sanitário e água cinza

The anaerobic treatment of sewage is widely employed in Brazil and it is an appreciated way for the treatment of effluents, helping to reduce the environmental impact in rivers. The methane gas obtained from the process can be applied to improve the energetic efficiency of the system, reducing the amount of waste and the cost of the treatment process. This work presents the net energy balance of anaerobic reactors applied to the treatment of sewage. The analysis was performed considering full-scale and laboratory-scale treatment systems. In laboratory scale, the results from three kinds of systems were compared regarding the biological treatment of greywater. Two of them (UASB7 and UASB12) were anaerobic and the other one was a combined anaerobic-aerobic system (UASB7/SBR6). Greywater methanization (compared to theoretical maximum) was calculated considering 100% removal (g BOD/day), the literature percentage removal and the anionic surfactant presence in the effluentt. For each of these three cases, the efficiencies were, respectively, 16.9%, 43.6% and 51.3% in UASB7 reactor, 25.6%, 50.3% and 59.2% in UASB12 reactor and 30.6%, 61.2% and 71.9% in UASB7/SBR6 reactor. The energetic potential was found to be 4.66x10-4, 7.77x10-4 and 5.12x10-4 kWh/L for the UASB7, UASB12 and UASB7/SBR6 reactors, respectively. The pumping system, the aeration (in the anaerobic-aerobic system) and the temperature controlled heating system were considered to calculate the energetic consumption. However, the third one was not employed since tropical regions like Brazil do not need heating systems and also because of its high energetic consumption. The calculated net energy balance in the reactors was negative in the case of greywater, respectively -0.16, -0.28 and -0.18 kWh/L for the reactors UASB7, UASB12 and UASB7/SRB6. In full scale (ETE Jardim das Flores - Rio Claro, SP), the average energy... (Complete abstract click electronic access below)

Personal trainer: (profissional, prestador de serviços, professor, valorização das diferenças e competências), um novo conceito de profissional

Baseado nas evidencias atuais de crescimento e expansão da atuação profissional do educador físico, em particular a sua atuação como prestador de serviços, ou seja, o personal trainer; que vende seus serviços, ou produtos relacionados à aptidão física e a relação promissora desta atuação, é que nos motivou a desenvolver este trabalho que segue por uma pesquisa bibliográfica de evidencias do histórico e perfil do personal trainer quanto aos conceitos culturais, sociais e psicológicos deste profissional, em seguida levantamos questões relacionadas à formação acadêmica do personal trainer e os pontos diferenciais deste profissional. Tais como a necessidade de conhecimentos que vão alem do âmbito acadêmico, pois se trata de um profissional prestador de serviços o que foge da regularidade da formação convencional. Portanto neste trabalho procuramos evidenciar estas e outras questões (como ética e profissionalismo), que podem levar este profissional a uma carreira de sucesso ou fracasso. Para isso existe uma necessidade fundamental de que se entenda que o personal trainer como prestador de serviços esta surgindo dentro de uma profissão já consolidada (Educador Físico), porem esta assumindo características próprias, como a necessidade de conhecimentos específicos da profissão. Concluímos, portanto que esta promissora atuação do educador físico necessita de atenções especiais e de um processo de formação diferenciado e que não podemos deixar que a nossa profissão se vulgarize e se venda por migalhas, pois esta é a grande chance do profissional se impor e conquistar o desejado respeito diante as profissões da área da saúde

A organização e seus relacionamentos: uma abordagem semiótica do conceito de público

The organizations now have felt some needs in regards to changes in attitudes in what refers to the relationship with their interest publics. In this way, this work has as objective approach different themes, like concepts of organizational culture and the interrelations with the profession of Public Relations, besides the contact with notions in the area of People Management and human capital. As all organizations are constituted by interest publics, it will also demonstrate theories that refer to the different kinds of publics which the organization maintains relationship with, although, giving special attention to the internal public, considered one of the main types of public. For better comprehension of the performance of the internal public it was used the greimassian narrative semiotics that allow an exploration and analysis os diverse procedures made by such public. Therefore, it was possible to observe a great contribution from the theory in what refers to the assertion of the importance in maintaining good relationships with the employees of an organization, specially to affirm the identity of the employee making use of factors such as culture, values, principals, norms etc. Thus, it is believed that the strategic communication must be used with the intention of proportioning personal and professional well being to the employees, in a way that they may feel more and more integrated and committed with the organization, granting, like so, the organizational development and recognition

O conceito de Ciência no seu processo de realização

A ciência é desenvolvida na relação entre pesquisador e objeto de estudo. Tal relação pode se dar de três formas, sendo elas objetiva, subjetiva e dialética. Ao se destacar num trabalho científico qual a relação que o autor desenvolve com seu objeto de estudo, é possível evidenciar indícios de seu conceito de ciência já que, muitas vezes, é a forma com que o pesquisador se relaciona com o objeto que irá guiar suas práticas e o conduzir pelo caminho a ser seguido. Para isso realizou-se uma breve revisão das relações entre o sujeito conhecedor e objeto conhecido presentes historicamente na atividade científica. Foram coletados e analisados trabalhos de diversos pesquisadores de um centro de investigação científica e classificados numa das formas de relação entre sujeito e objeto sendo os de atitude realista de maior número, seguidos pelos idealistas e por fim pelos que privilegiam a relação. Os trabalhos realistas apresentam, de forma geral, uma pequena preocupação com a reflexão sobre o significado de sua própria prática. Acredita-se que a ciência realizada nestes trabalhos seja da maior qualidade e sugere-se, para uma realização ainda mais totalizante, que ocorra a prática de incorporação de cada vez mais da ciência da ciência em seu cotidiano. Serão suas reflexões que nos possibilitarão um desenvolver de uma ciência mais significativa e transformadora, cabendo aos pesquisadores, utilizarem da ciência da ciência para pensarem as práticas e a tornarem cada vez mais dialógicas e complexas, assim como a natureza o é

História do desenvolvimento do conceito de força: um estudo visando contribuições para o ensino de física no nível médio

This study presents the results of a study on the development of the concept of force and their possible applications in physics teaching. The historical study has focused on Aristotelian natural philosophy, medieval theories of strength in impressed and on classical Newtonian mechanics. The Newtonian concept of force was also an object lesson of physics analyzed in this study. In this lesson, conducted in a preuniversity course, spontaneous conceptions or alternative conceptions of students about the concept of force proved very entrenched, resulting in studies on the Model Change on Conceptual and epistemological obstacles in view Bachelardian. The theoretical frameworks adopted led us to trace parallels between spontaneous conceptions revealed by the students and some views about the concept of force found in the study of history. The results show that while some old conceptions have been replaced by scientifically Newtonian concept of force, they are still present in the students' ideas and resist to changes even after the study of Newton's laws. Like main result shows that the history of science can be a great ally for the deconstruction of alternative conceptions, particularly when these concepts were previously presented and overcome the course of history of the development of a concept
