1. A quality assessment of titanium castings produced in an experimental short-heating-cycle investment
The aim of this study was to evaluate the quality of casting produced in an experimental short-term heating-cycle investment. Thus, reaction layer and castability of titanium casting using an experimental spinel-based investment (VR) with short heating cycle were compared with the commercial short-heating-cycle spinel-based investment Trinell (TR), the silic

2. Efeito da incorporação de fibras curtas de sílica amorfa em compósitos de polipropileno utilizados pela indústria automotiva nacional. / Effect of the incorporation of short amorphous silica fibers in polypropylene composites used by the national automotive industry.
The addition of silica fibers in polypropylene (PP) composites was investigated on this work as a proposal to develop new materials used in automotive industry, in order to enable the reduction of vehicle weight and the resulting fuel economy. The fibers are lightweight, made of amorphous silica and treated with amine silane for better interaction with the p

3. Morfo-anatomia e fitoquímica de Cymbopogon densiflorus (Steud.) Stapf e Cymbopogon nardus (L.) Rendle (Poaceae: Panicoideae) / Morphology, anatomy and phytochemistry of Cymbopogon densiflorus (Steud.) Stapf and Cymbopogon nardus (L.) Rendle
The genus Cymbopogon Sprengel belong to the Poaceae family and it has 40 species distributed in Tropical and Subtropical Africa, Asia and Australia, although some species went introduced in America. Many species of this genus are cultivated for the extraction of essential oil, from their leaves, with large medicinal, food and industrial importance. The speci

4. Avaliação das propriedades mecanicas e da morfologia de compositos ternarios de poliamida 6, borracha de etileno-propileno-dieno e fibras curtas de silica / Evaluation of the mechanical properties and the morphology of polyamide 6, ethylene-proyulene-diene rubber and short silica fibers ternary composites
The main goal of this work was to evaluate the incorporation of short silica fibers (SF) and ethylene-propylene-diene rubber, functionalized with maleic anhydride (EPDM-g-MA), in a polyamide 6 (PA 6) matrix. The fiber used as filler is a natural product made up of amorphous silica from the fossilization of multicelular animals. In order to promote a better i

5. Compositos elastomericos de fibras curtas de silica/silicona / Silica short fibers / silicone elastomeric composites
Neste trabalho, avaliou-se o desempenho de fibras curtas de sílica, natural ou modificada com viniltrimetoxissilano, como cargas primárias ou secundárias em uma matriz elastomérica de poli(dimetilsiloxano), PDMS. Além disso, foram comparadas as propriedades dos compósitos contendo fibras curtas com aqueles contendo quartzo natural, o qual é usualmente
