Viabilidade de turbinas eólicas de pequeno porte no Brasil

Facing a global scenario where oil is scarce and the emission of CO2 in the atmosphere is a world concern, the search for new methods of energy production becomes the focus of all countries. Based on these assumptions, the wind power gains highlight and happen to be the most exploited around the world, since this does not produce toxic waste, since it uses the wind, no raw material shortage and its cost and efficiency are increasingly attractive. Taking advantage of the geographical features of Brazil, coastal and territorial extension, this study aims to analyze the feasibility of using wind turbines widely used in Germany, one of the countries with the highest production of energy through wind, in Brazil. In order to increase the energy production without causing more environmental impacts, geographical analyses will be made, and to determine the features and costs of production of this type of energy generation, and at the end of this dissertation, will finish for one of the turbines, Montana, is it feasible to install, however due to the Government's little incentive return is not very expressive. With respect to the turbine Passaat, this is infeasible to install under current conditions

Análise de desempenho de lâmpadas LEDs e LFCs como alternativas em iluminação residencial em função da implementação da portaria ministerial n° 1007 que limita o uso de lâmpadas incandescentes no Brasil

With the imposition of the suspension of production and subsequent banning of incandescent light bulbs will be necessary to replace it by other more energy-efficient. Although the main alternative is the compact fluorescent lamp, the environmental impact caused by it due to incorrect disposal and the amount of harmonics included in the network resulting in losses related to the quality of electric power system makes them sought new alternatives for lighting systems that are efficient and have low environmental impact. In this context, the LED (Lighting Emitting Diode), based on solid-state components, is presented as an option for new projects and replacement of existing lighting. In this work we studied aspects of energy, environmental and economic impacts of a possible replacement of conventional lighting systems for new technology. From laboratory tests and surveys of the costs of different types of lamps used for residential lighting, we performed a comparative analysis considering energy and economic aspects which showed that the LED technology, but has a high initial investment, it is best when power quality and environmental preservation are relevant factors in decision making for the choice of technology to be used in the lighting system

Principais práticas e indicadores de sustentabilidade corporativa no setor de energia elétrica no Brasil

The questions involving environment and society have been increasingly considered into account when companies make business decisions. However many of them have not yet incorporated sustainability effectively in their business plan, sometimes performing only a few external actions and outside their area of expertise. The concept of corporate sustainability is within this context, and therefore the practice of companies consider, the environmental and social issues into their strategies, along with economic issues. This work has as main objective to identify what are the key indicators and related practices of the concept of corporate sustainability that has been introduced in companies on environmental reference of a certain sector of the Brazilian economy. The sector that was chosen is electric power, having enormous significance both in economy, society and environment. The results indicate that the main practice are in the areas of energy efficiency, security and good relationship with its key business stakeholders

Análise do consumo de energia elétrica e da eficiência energética em uma indústria de processamento de madeira

In the industries of wood processing (sawmills), where timber is sawn in equipment such as band saws, circular saws, trowel, thicknessers, among others, that mechanically transform this resource and use of electric motors, which are not unusually poorly scaled working or overloaded, often a factor that is not found in these industries and has fundamental importance in the production process is energy efficiency that is achieved by both technological innovation and through all the practices and policies that aim to lower energy consumption, lowering energy costs and increasing the amount of energy offered no change in generation. For both during the design of an electrical installation, both overall and in various sectors of the installation, investigations are necessary, considerations and uses of variables and factors that put into practice the theme of energy efficiency. Therefore, in this paper, these factors were calculated and analyzed for a wood processing industry (sawmill) in the municipality of Taquarivaí - SP, namely: active power, power factor, demand factor and load factor. Where they were small in relation to the literature, these events that occur when devices are connected at the same time and due to the conditions of processing the wood, where the engines have large variations in electricity consumption during the unfolding of the same, due to efforts with the load and idle moments between each machining operation in the equipment

Tratamento de efluentes provenientes de abatedouro de bovinos por meio de reator enzimático seguido de reator aeróbio operado em bateladas sequenciais

Brazil has one of the largest cattle herds in the world, so the cattle slaughter is one of the most important economic activities in the Brazilian market. But this activity requires a high demand of water, resulting in serious problems about the correct disposal of wastewater generated in the process. This effluent has a high pollution load, becoming its receiving bodies (streams and rivers) unfit for various activities such as public water supply, recreation, fisheries. To minimize the environmental impacts of its industrial wastewater and fallow the local environmental legislation, refrigerators must make the treatment of these effluents. This study aimed to verify the efficiency of a enzymatic reactor, when occur hydrolysis of lipids present in the effluent industrial of an cattle slaughter industry. The treatment system used was composed of two separate reactors: one being the anaerobic fluidized bed reactor (AFBR), inoculated with immobilized enzymes on the matrix support, and the other by sequential batch reactor (SBR) inoculated with activated sludge. Whereas, the reactors have been developed and installed at the Wastewater Treatment Laboratory, Faculdade de Ciências e Tecnologia, UNESP, campus Presidente Prudente. The procedure operating occurred differently for each reactor: preparation and inoculation of enzyme granules, filling the reactor, hydrolysis, and AFBR emptying, filling, aerobic reaction, sedimentation, and emptying the SBR. We performed three experimental stages, with the first and second stage of the work were done reactor analyzes separately, and the third step of the analysis were made with the interconnected reactors...

Educação e Hegemonia: A Formação de Intelectuais na Itália dos Anos 20, a Organização da Industrialização em São Paulo e a Construção da Hegemonia Burguesa no Brasil

The formation of intellectuals, in Gramscian terms (GRAMSCI, 2000), was addressed throughout our academic career, for example, Villela (2003; 2008; 2009; 2010-2012; 2011; 2012; 2014). This article aims to resume some relationships between education of intellectuals in Italy for years 1920, the organization of industrialization in São Paulo and the construction of bourgeois hegemony in Brazil. In this paper I review my dissertation, Villela (2003), whose aim was to understand the rationalization of work processes in architectural offices. This dissertation possible to trace, among other things, another story of the relationship between architecture and state in Brazil from industrialization in São Paulo. Based on the notion of intellectuals Gramsci, we discuss the extended state design and envision a particular kind of state, which in our case is the State industrialist. And relate interested in public policy of that State for industrialization industries office designed by Rino Levi Architects Associate SC Ltda. (ERLAA) that has developed over the decades its activities from 1920 to 1990, many projects in the city of São Paulo. The relationship proposed here is unprecedented. Grounded in this relationship, put in another scene about the formation of intellectuals and hegemony, a Gramscian point of view.

Relações comerciais entre China e América do Sul: os impactos na América do Sul e no Brasil

Com elevadas taxas de crescimento e participação cada vez maior no comércio mundial, a China intensifica suas relações com o Brasil e com a América do Sul, na qual apresenta-se como exportadora de manufaturados e importadora de commodities. Os efeitos desta relação devem ser estudados com cautela, pois apesar dos ganhos de curto prazo, geram perigosos impactos a médio e longo prazo. No Brasil, a presença chinesa é uma ameaça imediata ao setor industrial tanto no mercado interno, quanto externo

Eficiência das companhias aéreas brasileiras: uma análise envoltória de dados

Studies about efficiency have gained dimension, in Brazil, since the early 90’s. Same decade that the Civil Aviation System suffers important changes in terms of regulations. Such transformations have echoed effects currently, with some significant trend for international standards. This paper focuses on one of the agents from the Brazilian Civil Aviation System, the airlines companies, which aimed on analyze and evaluate both passengers and cargo air transport, by using data envelopment analysis (DEA), during the period of 2005 to 2010. The yearbooks of ANAC, corresponding at the period from 2005 to 2010, were used as data base in this present study. The technique was applied to 14 companies, which through Stepwise process of variables validation was possible to compose a compact, but complete model, that could translate the reality of companies. This model was composed by one output, Total Income, and by four inputs, Total Costs, Total Domestic Passenger, Total Cargo and Total International Passengers. However, this approach has some flaws. Therefore in order to remedy it, it was required to apply the method Frontier Inverted, one of the alternatives proposed in the literature, which ensured an improvement in the context of efficiencies due to biggest discrimination of airlines. As a result of the DEA-BCC process, oriented by output, TAM 2005 was considered the most efficient company, however GOL and Webjet companies concentrated in 2007 their worst levels

Políticas Industriais e de Ciência, Tecnologia e Inovação na Irlanda: ênfase em setores de alta tecnologia e comparação com o Brasil

From a theoretical foundation favorable to industrial policies, this paper intends to show the main policies followed by Ireland since the 1950s, with a special emphasis on those directed to Science, Technology and Innovation (S,T&I), FDI and high tech sectors, like software and biotechnology. We compare these policies with those used in Brazil, in a similar period, in order to have some hints for virtual transformations of current Brazilian policies. We conclude that the compromise of the State with the direction of the development and the continu-ity of industrial policies is very important to a solid building of comparative advantages in technologically dynamic sectors.

A distribuição espacial da indústria do vestuário no Brasil

This paper aims to analyse the spatial distribution of the Brazilian clothing industry in 1997 and 2006. In order to achieve this objective, this study used an exploratory spatial data analysis - ESDA. It was made a univariate analysis of the number of the existing clothing industries among Brazilian states. The null hypotheses of the spatial dependence absence was rejected and the construction of cluster maps showed two patterns: a high industrial concentration and a low one. On the other hand, a bivariate analysis was also conducted to permit a study between the number of clothing industries and the wage income of the neighbor regions. The result revealed spatial dependence besides similar cluster maps in both years. Therefore, two spatial patterns emerged: a high and a low industrial concentration. The final conclusion is that agglomeration economies are the main responsible for the results found in both analyses.
