1. Estudo comparativo e experimental de materiais aplicados a insertos macho de moldes de injeção dentro do conceito de molde híbrido
The application of plastic components has grown significantly in most of industrial segments during last years. This has attracted considerably attention for the injection mould design and manufacturing processes, which is one of the most expensive phases of injected plastic components development process. Techniques such as Rapid Prototyping/Rapid Tooling h

2. Sistema porta hepático do bagre africano Clarias gariepinus Burchell, 1822 (Clariidae, Siluriformes, Ostariophysii) / Hepatic portal system of the African catfish Clarias gariepinus Burchell, 1822 (Clariidae, Siluriformes, Ostariophysii)
The hepatic portal system of the African catfish Clarias gariepinus Burchell, 1822, was studied considering the macroscopic and microscopic anatomy, by means of several anatomic techniques, including anesthesia, injection of substances recommended to the study of the vascular system (latex, Indian ink, polyvinyl chloride and radiopaque substance), dissection

3. Heat flux canals (HFC) technique: an alternative to cool down stereolithography moulds
The design of injection mould inserts obtained by stereolithography (SL) has various recommendations that are based on experimental work done by researchers over the last decade. There are no final conclusions about the best cooling technique for SL inserts. Moreover, no criteria are presented concerning structural and thermal designs based on stress-strain

4. Confecção e caracterização óptica e estrutural de lentes plásticas obtidas pelo processo de injeção / Production and characterization optic and estructural of plastic lens made by injection process
The purpose of this work was the development and production of acrylic biconvex lens by injection process to be used in optical and science teaching at elementary and high schools. The importance of such work is based in the deficiency of experimental didactic material made in Brazil. In order to achieve the intended objective it was necessary to study the t
