1. Produção de bioetanol a partir de resíduos agroindustriais
Concerns about global warming and the depletion of petroleum cause the search for alternative fuels from renewable sources. The current study aims at obtaining bioethanol from fermentable sugars extracted from hydrolyzed residues in situ by solid-state fermentation (SSF). The first stage was the SSF for the hydrolysis of the culture medium which is composed

2. Estudo da transformação durante o resfriamento continuo e da microestrutura do aço microligado X80 utilizado na construção de tubos para transporte de gás natural e petróleo. / Study of the transformation during the continuous cooling and the microstructure of microalloyed steel X80 used in the building of pipelines for gas and oil transport.
The continuous increase of energy generated from petroleum and natural gas created the need to improve the mechanical properties of microalloyed steels used in gas and oil pipelines, in order to increase their flow with smaller costs and higher reliability. The control of the different phases, morphology of microconstituents like ferrite plus carbide aggrega

3. Plastic behavior of medium carbon vanadium microalloyed steel at temperatures near gamma <-> alpha transformation
Dilatometric techniques were used to build the continuous cooling transformation (CCT) diagram for a medium carbon microalloyed steel; the microstructure and hardness were determined at different cooling rates. The mechanical behavior of the steel in the austenite field and at temperatures approaching austenite to ferrite transformation was measured by means

4. Caracterização da temperabilidade de um aço C-Mn microligado ao boro, através de dilatometria e curvas de transformações de fases por resfriamento contínuo. / C-Mn boron microalloyed steel hardenability characterization throught dilatometry and continuous cooling transformations curves.
No presente trabalho, foi realizado um estudo sobre a influência da adição do boro em um aço C-Mn, nas transformações de fases por resfriamento contínuo, através da técnica dilatométrica. Para este estudo, utilizou-se dois aços de composição química semelhante: o aço 10B22 com 30 ppm de boro e o aço sem boro é o E1522, equivalente. Foram tra
