15. MODELING OF THE USE OF NANOFLUIDS IN INTERNAL COMBUSTION ENGINES COOLING SYSTEMS / MODELAGEM DO USO DE NANOFLUIDOS NO SISTEMA DE ARREFECIMENTO DE MOTORES A COMBUSTÃO INTERNA
The application of nanofluids in cooling systems of internal combustion engines was studied. Nanofluids consist of nanoparticles (with dimension below 100 (u)m) suspended in traditional heat transfer fluids, such as water or ethylene glycol. Given their favourable heat transfer characteristics, because of the suspension of high thermal conductivity particles

18. ÉSTERES COMBUSTÍVEIS EM MOTOR DE CICLO DIESEL SOB CONDIÇÕES DE PRÉ-AQUECIMENTO E VARIAÇÃO NO AVANÇO DE INJEÇÃO / ESTERS FUELS IN DIESEL ENGINES UNDER PRE-HEATING CONDITIONS AND VARYING INJECTION TIMING
The renewed interest in energy for biomass is supported by the need for different energy sources and the need to protect the environment. Recently, because of increases in crude oil prices, limited resources of fossil oil and environmental concerns there has been renewed focus on vegetable oils and animal fats to make a biodiesel fuel. What is known as biodi

19. Development and implantation of an operational setup designed for the evaluation of new tracers for oil reservoir characterization / Desenvolvimento e inplantação de um sistema operacional para a qualificação do desempenho de novos traçadores para reservatórios de petróleo
Petroleum, nowadays, is one of the most important natural resources in the world, since it is one of the main primary sources of energy and also raw material for many different products. It can be found accumulated in the subsoil, and was produced from the remaining portions of animals and vegetables, in a process that took millions of years to be concluded.
