1. Processos de inovação tecnológica para a glicerina produzida no processo de obtenção de biodiesel no Brasil
Biodiesel is considered as a viable alternative to partially replace fossil fuels. The manufacture process of biodiesel produces approximately 10% glycerin, the main byproduct. Due to the growth of the biodiesel industry in Brazil and abroad, the high volumes of glycerin become a bottleneck in this chain, given that currently use the glycerin market serves a

2. Integrating time series mining and fractals to discover patterns and extreme events in climate and remote sensing databases.
This thesis presents new methods based on fractal theory and data mining techniques to support agricultural monitoring in regional scale, specifically regions with sugar cane fields. This commodity greatly contributes to the Brazilian economy since it is a viable alternative to replace fossil fuels. Since climate influences the national agricultural producti

3. O Protocolo de Kyoto e o mercado de crédito de carbono: estudo de caso das emissões de gases de efeito estufa da fábrica de combustível nuclear pertencente às Indústrias Nucleares do Brasil no ano de 2008 / The Kyoto Protocol and the carbon credit market: case study of emissions of greenhouse gases from nuclear fuel factory belonging to the Nuclear Industries of Brazil in 2008
This dissertation discusses issues related to intensification of climate change by anthropogenic causes for the evolution in use of natural resources, innovations in production processes, economic, social, cultural, political and especially environmental. Approaches marketing of carbon credits through projects of Clean Development Mechanism (CDM), one of the

4. A strong argument for using non-commodities to generate electricity / A strong argument for using non-commodities to generate electricity
Usa-se controle Ãtimo para analisar o trade-off entre o uso das fontes primÃrias consideradas commodities como combustÃveis fÃsseis, biomassa e Ãgua para gerar eletricidade versus outros usos econÃmicos (indÃtria petroquÃmica, produÃÃo de combustÃveis, agricultura, siderurgia, entre outros). Para isso, um modelo dinÃmico que estabelece relaÃÃes

5. Utilização de células a combustível tipo PEM como alternativa na geração auxiliar em instalações elétricas de grande porte. / The use of PEM type fuel cells as an alternative to auxiliary generation of large eletrical instalations.
The current global energy situation shows the dependence on the electric energy, and the importance of the rational use of energy and the reduction of pollutants in the production of energy. The hydrogen as source of generation of electrical energy in fuel cells uses an abundant resource in Earth, and produces electrical energy with no pollution. The fuel ce

6. Studies of air pollution in the municipal district of Sete Lagoas, MG using nuclear techniques / Estudos da poluição do ar do município de Sete Lagoas, MG utilizando técnicas nucleares
Toxic metals, such as Ni, V, Zn, Cu, Cr, Mn and metalloids as As and Se and their compositions are associated mainly with the smaller diameter particulates present in the atmospheric aerosols. This fact is important, principally, when it concerns public health, because this is considered the breathable fraction of particles that can penetrate deeply into the
