14. Um Estudo da Qualidade do Ar na Cidade de Fortaleza. / A Study of Air Quality in the city of Fortaleza.
The quality of life for people around the world has a direct relationship with the ambient air quality, resource essential to life. Population growth in urban centers has contributed profoundly to the increased emission of pollutants into the atmosphere, mainly by burning fossil fuels and other actions of anthropogenic nature. Cities like Tokyo, Beijing, New

15. Reactivity of brazilian coal, charcoal, imported coal and blends aiming to their injection into blast furnaces
For about 10 years the steel industry in Brazil has used pulverized coal injection (PCI) technology in the blast furnaces based on imported coals. In order to decrease the dependence on imported coals, Brazilian coal, which has limited use due to high ash content, was suggested to be mixed with imported coal and charcoal. The aim was to examine the reactivit

16. Assessment of the consequences of the concrete production in Brazil for the climate change. / Avaliação das conseqüências da produção de concreto no Brasil para as mudanças climáticas.
The Brazilian concrete sector contributes to the climate change due to its CO2 emissions, that can be reduced through efforts of the cement sector, that have been receiving great attention. But the use of the cement in concrete can increase its consumption if made in the wrong way, and this can increase the CO2 emissions, making important the study of the em

17. Dinâmica do carbono e fluxo de gases do efeito estufa em sistemas de integração lavoura-pecuária na Amazônia e no Cerrado / Carbon dynamics and greenhouse gas fluxes in integrated crop-livestock systems in Amazonia and Cerrado
Changes on land use and management influence the accumulation of carbon (C) in soil and the greenhouse gas (GHG) fluxes. In Brazil, especially in Amazonia and Cerrados biomes, the native vegetation has been historically converted in pastures and agriculture causing considerable amount of GHG emissions to the atmosphere. Recently, pastures and agricultural ac

20. Mapping greenhouse gases in the state of Bahia with the aim to reduce it wite energy efficiency initiatives and energy inputs substitution / Mapeamento das emissões de gases do efeito estufa no estado da Bahia com perspectiva de redução a partir de ações de eficiência energética e substituição de energéticos
The objective of this thesis is to analyze the consumption of energy among the segments of the economy of the State of Bahia and to create a matrix of greenhouse gases emissions in the state. Policies based on increasing the energy consumption efficiency and replacement of energy sources by less emitting ones could then be identified. The research is based o
