25. UMA FORMULAÇÃO DE ELEMENTOS FINITOS AXISSIMÉTRICOS PARA ANÁLISE DE TUBOS LAMINADOS EM MATERIAIS COMPÓSITOS / AN AXISYMMETRIC FINITE ELEMENT FORMULATION FOR THE ANALYSIS OF LAMINATED COMPOSITE TUBES
The use of composite materials in structures has grown in the engineering practice due to its characteristics, of high strength, low density and a good stability to thermal effects. A class of composites, the fibrous laminates, is generally used in tubes subjected to many types of loadings as internal and/or external pressure, traction, torsion, temperatures

26. 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

27. Avaliação da resistência lateral em estacas escavadas com trado submetidas à tração / Evaluation of the lateral strength in augered piles submitted traction
Com a finalidade de determinar e avaliar a resistência lateral em estacas escavadas com trado sem o uso de lama bentonítica solicitadas à tração, foi executado neste trabalho uma série de ensaios de campo (PMT, DMT, SPT e SPT-T) e laboratório (granulometria conjunta, limites de consistência, massa específica dos sólidos e ensaios triaxiais), atrav�

28. Effects of neuromuscular electric stimulation during the immobilization in the mechanical properties of the skeletal muscle. / Efeitos da eletroestimulação neuromuscular durante a imobilização nas propriedades mecânicas do músculo esquelético
The neuromuscular electric stimulation (NMES) is an important tool used in sport medicine to accelerate the recovery process. The objective of this study was to analyze the effects of NMES during the immobilization of the gastrocnemius muscle, in lengthened (LP) and shortened positions (SP). Sixty young female rats WISTAR were distributed into six groups and

29. "Avaliação da resistência a tração de reparos em resina composta". / Traction strength assessment of repairs in composite resin
The aim of this study was to evaluate in vitro the tensile bonding strength of repairs in composite resin using an adhesive system, with or without the previous use of silane on the junction of test bodies submitted to traction tests. The test bodies were prepared in a stainless steel device that provides the shape of a dumb-bell. Eighty half-test bodies wer

30. Exploitation of carbon fiber and glass fiber to reinforcements of timber beams. / Utilização de fibras de carbono e de fibras de vidro para reforço de vigas de madeira.
The necessity of rehabilitation and reinforcement in wood structures, concrete and steel demanded a search for more efficient methods that could to carry this paper. With this objectives several studies are using fibers reinforced polymers (FRP). These fibers which presenting better results in structural reinforcement for structural pieces of wood are the fi

31. Influência da termociclagem e do tratamento superficial da resina acrílica na resistência à tração da união com materiais reembasadores resilentes
The purpose of this study was to analyze the effect of thermo cycling and surface machining in the acrylic resin (QC-20) on the tensile bond strength with permanent soft liners (Eversoft, Mucopren Soft). Two hundred-forty samples were made and distributed in twenty-four variables groups with ten samples each group For making the samples, metal matrixes wer

32. Processos adaptativos do tecido muscular esqueletico e tecido conjuntivo : repercussões sobre a flexibilidade
This study has as its objective to discuss the control mechanisms of structural adaptations in the connective and muscular tissues under different functional conditions. It consists in the development of the interpretations about the plasticity of the tissues related to physical activities in order to improve the motor system s flexibility. Therefore, this b

33. Lifetime and Strength of Periodic Bond Clusters between Elastic Media under Inclined Loading
Focal adhesions are clusters of specific receptor-ligand bonds that link an animal cell to an extracellular matrix. To understand the mechanical responses of focal adhesions, here we develop a stochastic-elasticity model of a periodic array of adhesion clusters between two dissimilar elastic media subjected to an inclined tensile stress, in which stochastic
