25. LATEX MEMBRANE USED LIKE IMPLANT TO CORRECT MUSCLES DEFECTS IN DOGS AND RABBITS / A MEMBRANA DE LÁTEX COMO IMPLANTE PARA CORREÇÃO DE DEFEITOS MUSCULARES EM CÃES E COELHOS
This dissertation presents an implant model of natural latex to be used on partial canine diaphragm replacement. The implant could be used in cases of diaphragmatic hernias, or significant loss of the diaphragm integrity disabling its reconstitution. For such, seven different membranes had been tested, six of them had been produced experimentally and one is

26. Treatment corona on surfaces textiles / Tratamento corona sobre superficies texteis
Amongst the techniques of modification of surfaces applied in the industry to improve adhesion, the treatment for discharge corona widely is used. During the treatment for discharge corona, active species are generated, which can consequently react with the surface of polymer causing chain in addition and formation of radicals, thus creating polar groups in

29. Effect of snake venom derived fibrin glue on the tendon healing in dogs: clinical and biomechanical study
The aim of this study was to evaluate the effect of snake venom derived fibrin glue on the strength oftendon healing in dogs. The deep digital flexor tendon of the 5th digit of 24 thoracic limbs was partially sectioned for adhesive application. On the 7th, 15th, and 30th postoperative day tendons segments were removed for the clinical and biomechanical study

30. Preparation and characterization of silk fibroin membranes to use as biomaterial / Obtenção e caracterização de membranas de fibroina de seda para aplicação como biomaterial
Fibroin is a fibrous protein, also found in silk. Recently, several researchers have investigated silk fibroin as a promising resource for biotechnology and biomedical materiaIs due to its mechanical resistance, biocompatibility and minimal inflammatory reaction. Based on these characteristics, other applications have been proposed, as wound protection, subs

31. Contribution to the study of the application of alternative materials in the composites based on Portland cement : use of polypropylene grains recycled in substitution to the aggregates of the concrete / Contribuição ao estudo da aplicação de materiais alternativos nos compositos a base de cimento Portland : uso de grãos de polipropileno reciclado em substituição aos agregados do concreto
The main objective of this dissertation was the determination of the main mechanical properties of a composite based on Portland cement CP-V-ARI (high initial resistance) tends as aggregate the grains recycled agglutinated of polypropylene (GRAP). The choice of the plastic is due to the fact that it is one of the main materials used by the industry in genera

33. Resistência à tração dos componentes músculo-aponeuróticos da parede abdominal, em cadáveres, com e sem incisão da aponeurose do músculo oblíquo externo na linha semilunar. / Resistance to traction of the abdominal wall components, in cadavers, with and without incision of the external oblique aponeurosis along the semilunaris line.
Introdução: Os defeitos da parede abdominal são freqüentes e devem ser preferencialmente tratados com técnicas que utilizem tecidos do próprio paciente e permitam a redução da tensão ao fechamento das margens do defeito. As técnicas de incisão e descolamentos músculo-aponeuróticos da parede abdominal têm sido utilizadas com o objetivo de reduzi
