1. Aquisições, fusões e alianças estratégicas na configuração da cadeia sucroenergética brasileira / Acquisitions, mergers and strategic alliances in the configuration of the Brazilian sugar, ethanol and bioenergy chain
A cadeia do açúcar tem sido um dos ícones da economia brasileira por séculos. Em meados da década de 1970, ela passou pela primeira mudança expressiva, a introdução do Proálcool, programa de combustível alternativo apoiado pelo governo. Após a recente virada do século, a cadeia sucroalcooleira passou por nova mudança, dessa vez fomentada pela te

2. The hydrolysis of agro-industrial residues by holocellulose-degrading enzymes
Holocellulose structures from agro-industrial residues rely on main and side chain attacking enzymes with different specificities for complete hydrolysis. Combinations of crude enzymatic extracts from different fungal species, including Aspergillus terreus, Aspergillus oryzae, Aspergillus niger and Trichoderma longibrachiatum, were applied to sugar cane baga

4. Produção de cana-de-açúcar para obtenção de etanol hidratado no Rio Grande do Sul : uma análise utilizando dinâmica de sistemas
Brazilian use of sugar cane ethanol in its energy matrix has been gaining international recognition. With a growing fleet of flex fuel vehicles, Brazil has been building an each year greater demand for ethanol. Nevertheless, consumption levels throughout the country are not homogeneous. Far from sugar cane production centers and with one of the nations highe

5. Processo simplificado para a produção de concentrado de acidos graxos de cadeia longa (D-003) a partir da cera de cana-de-açucar (Saccharum officinarum L.) / Simplified process to production of concentrated long chain fatty acids from sugar cane wax (Saccharum officinarum L.)
The sugar cane (Saccharum officinarum L.) wax obtained from filter cake, a byproduct of the sugar and alcohol industries, has attracted great interest due to the large potential for application in various industrial sectors, including the pharmaceutical industry. Brazil is the largest sugar cane producer and sugar exporting country in the world, making it a

6. Governança ambiental em território dependente do agronegócio no setor sucroalcooleiro / Governança ambiental em território dependente do agronegócio no setor sucroalcooleiro
This research seeks to identify the converging factors towards environmental governance in Brazils sugar cane agribusiness dependent territories, in view of the trends of expansion of the cultivating areas, as a result of the internal and external demands for the ethanol in substitution to fossil fuel. This work has been organized in three major blocks. The

7. Sewage sludge application in cane-plant as nitrogen and phosphorus source and its environmental effects / Aplicação de lodo de esgoto em cana-planta como fonte de nitrogênio e fósforo e seu impacto ambiental
The potential agricultural use of the sewage sludge is due to their organic matter and nutrients contents, mainly nitrogen and phosphorus, the most important constituint. However, there is a lack of research to adequate the nitrogen and phosphate fertilizer doses to be applied in agricultural fields treated with this residue. Despite the evident benefits of

8. Modificação de linhagens industriais de Saccharomyces cerevisiae para o aumento da produtividade de alcool e floculação condicional / Genetic modification of industrial Saccharomyces cerevisiae strain to improve ethanol production and conditional flocculation
The increased need for replacing energy sources from fossil oil to renewable sources has prompted research initiatives throughout the world. Bioethanol is a highly competitive candidate to replace fuels such as gasoline. The production of Brazilian ethanol occurs by the fermentation of sugars from sugar cane juice by the yeast Saccharomyces cerevisiae. The i

9. Dinâmica econômica das flutuações na produção de cana-de-açúcar / Economic dynamics from fluctuations in the Brazilian sugar cane production
Since the mid 70s, the Brazilian sugar and ethanol markets have passed through noteworthy changes, leading the country back to the position of number one sugar cane producer in the world. The objective of this thesis is to evaluate the whole of shocks in supply (measured by area and yield unexpected variations), in demand (measured by domestic income and exp

11. Limites e possibilidades de desenvolvimento da cadeira produtiva do álcool: um estudo de caso no Rio Grande do Sul
The actual energetic context is characterized by environmental problems caused by de industrial developing and by the high value of oil (energetic base of the developing model) witch leads us to the search of alternatives (renewable energies), that may complement or replace the actual existing energy chain. In this reality the development in Brazil is remain

12. Decision making in envestimentos the production of oil for the biodiesel industry, focusing on small and medium enterprise: an approach of discriminant analysis and factor / Tomada de decisão em envestimentos na produção de oleaginosas para o setor do biodiesel, com foco na pequena e média empresa:uma abordagem de análises discriminantes e fatorial
Brazilian median and small biooil country producers working on the Biodiesel production chain normally need the aid of public policies to guide the sector to sustainable development with social inclusion. Those policies are necessary to avoid the concentration of production in few large producers, as it has happened with sugar cane ethanol supply chain in Br
