1. Converting a Conventional Vehicle into an Electric Vehicle (EV)
Abstract The electric vehicle (EV) is not a recent invention. Between the end of the XIX century and the beginning of the XX century, most motor vehicles were electric, due to their superior reliability and cleanliness, compared to that of vehicles driven by internal combustion engines (ICE). However, with the development of ICEs and the reduction of their p

2. Evaluation of Biomass Properties for the Production of Solid Biofuels
ABSTRACT The efficient use of biomass as fuel requires prior knowledge of the composition and properties of the material in order to be able to develop technologies for its efficient combustion while ensuring that emissions of pollutants remain within acceptable limits. Therefore, the analysis of the physical and chemical properties of these materials is ess

3. Exposição ao uso da lenha para cocção no Brasil e sua relação com os agravos à saúde da população
Resumo A poluição do ar em ambientes fechados é agravada pela queima de lenha em fogões rústicos e ambientes pouco ventilados. A exposição aos poluentes emitidos por este tipo de combustível resulta no aumento da morbidade e da mortalidade. No Brasil, os estudos e as estimativas são escassos. Visando entender esta problemática, o objetivo deste tra

5. Association between NOx exposure and deaths caused by respiratory diseases in a medium-sized Brazilian city
Exposure to nitrogen oxides (NOx) emitted by burning fossil fuels has been associated with respiratory diseases. We aimed to estimate the effects of NOx exposure on mortality owing to respiratory diseases in residents of Taubaté, São Paulo, Brazil, of all ages and both sexes. This time-series ecological study from August 1, 2011 to July 31, 2012 used infor

6. Experimental Valuation Diagnostics of Hydrous Ethanol Sprays Formed by a Blurry Injector
ABSTRACT: Concerns about the rising fuel price and environmental changes have led to the search for alternative fuels and energy sources. The interest in improving the performance of power generation, with the aim of reducing costs, increasing operating efficiency, and reducing the emissions of pollutants, has driven the scientific community to work on new b

7. Caracterização de biomassas brasileiras para fins de aproveitamento energético / Characterization of brazilian biomasses for energy recovery
New energetic alternatives have been the subject of discussion about conservation of natural resources. Such discourses are based mainly on reducing emissions of greenhouse gases and other pollutants, caused mostly by the use of fossil fuels, major source of energy today. In view of the applicability of biomass as energy input, this paper presents an experim

8. Estimativa da emissão de poluentes pelo setor de transporte e análise das ocorrências de doenças respiratórias na área de proteção ambiental do Sistema Cantareira / Estimation of pollutant emissions by sector and transport analysis of respiratory diseases in the area of environmental protection System Cantareira
The global energy matrix is mainly composed by fossil fuels which when burned release air pollutants that affect the environment and human health. In this sense, monitoring health problems related to air pollution is important because it reinforces the need for change in national and international energy policies. This thesis presents a discussion on air pol

9. AdsorÃÃo de MolÃculas Sulfuradas AromÃticas em Adsorventes Mesoestruturados à Base de SÃlica. / Adsorption of aromatic sulfur molecules on mesostructured silica adsorbents.
The demand of a larger control in the emission of pollutants from automobiles, with a reduction in the emission of sulfur, has led to an intense research effort on techniques of sulfur removal from fuels. In the last few years, adsorption is thought to be a suitable polishing technique to achieve a deep desulfurization of streams from hydrodesulfurization (H

10. 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

11. Efeitos do sistema de recirculação dos gases de escape no controle de emissões de NOx em motores a diesel / Effects of exhaust gas recirculation to control NOx emissions in Diesel engines
Automotive vehicles are responsible for the most of locomotion in the modern world. The mainly propulsive energy used is based on burning of fossil fuels. In real combustion systems the chemical process involved a high complexity which results mainly in five types of air pollutants, that are, carbon monoxide, organic compounds as hydrocarbons unburned or par

12. Poluição veicular: Avaliação dos impactos e benefícios ambientais com a renovação da frota veicular leve na cidade de São Paulo / Vehicle pollution: Analysis of the impacts and environmental benefits concerning the replacement of light vehicles in São Paulo City
This study presents an analysis of the levels of vehicles emissions related to the pollution problems in São Paulo City. Using a methodology called bottom-up, this thesis presents a theoretical evaluation on the rates of pollutants coming out the exhaust pipe of the largest light vehicles fleet in Brazil. Issues related to daily city activities such as the
