1. Fabricación y caracterización de espumas de alúmina para aplicación en quemadores porosos radiantes
In radiant porous burners, the heat source requires a solid porous matrix where the combustion reaction takes place, in which the heat transfer is performed more efficiently. This work is based on a study of the alumina suspension rheology, where parameters as viscosity and tixotropy were the guide to select the appropriate formulation for the ceramic foam f

2. Estudo comparativo de estrutura/propriedades da liga A1-Si5-Cu3-Mg nos estados fundido e tixoconformado, para utilização em componentes de motores / Comparative study of structure-properties from A1-Si5-Cu3-Mg alloy by casting and thixoforged, for use in engine components
The goal of this work was the comparative study between the Al-Si5-Cu3-Mg alloy obtained by die casting and thixoforging, based on a commercial accessories bracket used in diesel engines. The die casting commercial part was characterized in terms of structure and mechanical properties, and the final sample obtained by thixoforging was characterized in the sa

3. Estudo reologico dos amidos de amaranto, de mandioca e de suas misturas, sob condições de acidez e tratamento termico / Rheological study of cassava and amaranth starches and their blends under heat treatment and acidity
Starch has been widely used as a thickener, stabilizer or gelling ingredients in the food like soups, sauces, snacks, canned and refrigerated food products. In this foods processing, starch dispersion are often heated, cooled and pumping at a wide range of shear rate. In many foods, sours substances (various acids) are added to foods as acidulents or preserv

4. Estudo das argilas que recobrem as camadas de gipsita da bacia sedimentar do Araripe
As argilas que capeiam o horizonte de gipsita da bacia sedimentar do Araripe sÃo constituÃdas por uma assemblÃia mineral diversificada, onde participam, alÃm de argilominerais (predominantes), uma fraÃÃo detrÃtica grosseira composta essencialmente por quartzo, feldspatos e, principalmente, por calcita e gipsita. Os argilominerais presentes nessas argi
