1. Um estudo dos processos de regulação e governança socioambiental do setor sucroalcooleiro no Brasil
In the last five years, there was an increase the ethanol production in Brazil, thanks to the ex-pansion of this sector in the Brazilian Cerrado. Despite all the scientific and technological development for sustainable production of ethanol, the environmental, social and labor also affect the credibility of the product, both domestically and externally. Alon

2. A atuação do complexo agroindustrial canavieiro em rede : o exemplo de Nova Luzitânia-SP
The aim of this research was to analise the evolution of the production processes and work at the mesoregions of São José do Rio Preto and Araçatuba, mainly at the microregions of Auriflama and Araçatuba specifying the city of Nova Luzitânia. In these was developed the Agro-industrial Complex operating through the geographics nets. In order to better un

3. "Resistência à Corrosão de Aços Inoxidáveis em Solução Sintética de Condensado de Álcool Combustível / "Resistência à Corrosão de Aços Inoxidáveis em Solução Sintética de Condensado de Álcool Combustível
Nowadays a great effort had been directed to research work in order to attend the environmental protection agencies demands for minimizing the levels of gases emission pollutants. The consumers requirements for more economic and durable vehicles had motivated also the researchers to look for more corrosion resistance materials in order to substitute the trad

4. Estudo molecular e morfológico de leveduras de processos fermentativos de produção de etanol
Leveduras são microrganismos considerados de grande importância econômica por participarem de diversos processos industriais de fermentação. Linhagens comerciais de Saccharomyces cerevisiae, selecionadas por melhor se adaptarem a processos industriais, são utilizadas como inóculo na produção de álcool combustível. Durante o processo de produção

5. Soybean oil ethanol extraction and ethyl esterification in miscellae / Extração de óleo de soja com etanol e transesterificação etílica na miscela
The present models of biodiesel production is based on biodiesel plants regardless of the oil extraction industry location, causing many logistic problems and fails on the system, which in order not to go unactive, adopts unusual fat sources, raising the costs of the final product, and losing market competitiveness to diesel fuel. In this paper, we developed

6. Prospective analysis of the pattern of expansion of the sector sucroenergético Brazil: an application of probabilistic models with data-georeferenciated / Análise prospectiva do padrão de expansão do setor sucroenergético brasileiro: uma aplicação de modelos probabilísticos com dados georeferenciados
With expectations of a growing international market for biofuels, where Brazil would be a natural leader in the ethanol, several questions arise regarding the sustainability of Brazilian ethanol expansion: what would be the environmental, social and economic inpacts of sugarcane expansion in a scenario of significant ethanol exports? What regions would be mo

7. Acidentes com transporte rodoviario de produtos perigosos : analise e aplicação de modelo conceitual georreferenciado para avaliação de risco ambiental no minicipio de Campinas- SP / Highway transportation of hazardous materials accidents : characteristics and use of a conceptual model for analyzing environmental risk at Campinas, São Paulo State, Brazil
Highway accidents involving a vehicle transporting hazardous goods may cause extensive material, human and mainly environmental damage. Most of the areas crossed by highways are environmentally vulnerable due to the presence of creeks and rivers, different land use and possibility of the ground water being reached by the transported products. The county of C

8. Avaliação exergética dos efluentes do processo industrial do álcool / Exergetic assessment of effluents in the industrial alcohol process
In the production of ethyl alcohol as a fuel, the sugar and alcohol industry captures large volumes of water for steam generation, for cooling and as part of the process, generating large amounts of effluents. Using the energy produced by the burning of bagasse in the furnace for the transformation of water into steam, the industry generates its own electric

9. A desregulamentação e o desempenho do complexo sucroalcooleiro no Brasil.
This work analyzed the evolution of the relation between the sugar and alcohol complex and the State from 1975 to 2002, when there was a change from public intervention, marked by Proálcool, to a new situation, in which deregulation is proposed. We attempted to interpret the main political and economical stipulators of the process, as well as describe the w

10. Industrial process modeling of continuous alcholic fermentation in cascade bioreactors / Modelagem de processo industrial de fermentação alcoolica continua com reatores de mistura ligados em serie
This work aimed to determinate a model that best describes the industrial scale alcoholic fermentation in continuous serial mixing reactors. Software was developed in order to establish the kinetics parameters, using analysis data performed on samples from operating plants. The models described by Tosseto (2002), Lee; Pagan; Rogers (1983) and Levenspiel (198

11. SENSOR DISCRIMINATIVO A FIBRA ÓPTICA PARA DETECÇÃO DE VAZAMENTO EM TANQUES JAQUETADOS / OPTICAL FIBER SENSOR DISCRIMINATOR FOR JACKETED TANKS LEAKAGE DETECTION
Soil contamination due to leakage of hydrocarbon fuels from tanks in service stations is an environmental risk associated with the distribution segment of the petroleum industry. Such risk is closely related to ageing tanks and piping systems, as well as to the lack of quality assurance practices in service stations. This problem is being reduced during the

12. Desenvolvimento sustentavel : uma analise do alcool como alternativa energetica
World energetic matrix based on combustible fossils, more importantly oil has shown signs of unsustainability. The reasons for this are related to both production structure, which needs to be diversified as to incorporate new sources of energy, and also to the actual pattern of consumption. There is plenty of evidence to suggest that humankind evolution will
