1. Graft tendon slippage with metallic and bioabsorbable interference screws under cyclic load: a biomechanical study in a porcine model
Introduction The rupture of the anterior cruciate ligament (ACL) is the most common type of knee injury. Reconstructive surgery is the ‘gold standard’ treatment. During the immediate post-operative period, the fixation of the graft is entirely dependent on the ability of the grafted implant to be secured inside the bone tunnel under the cyclical loads a

2. Biomechanical analysis of the acetabular buttress-plate: are complex acetabular fractures in the quadrilateral area stable after treatment with anterior construct plate-1/3 tube buttress plate fixation?
OBJECTIVE: The acetabular buttress-plate has been widely used in treating difficult cases with satisfying clinical results. However, the biomechanical properties of a postoperative acetabular fracture fixed by the buttress-plate are not clear. The purpose of this study was to evaluate the biomechanical properties of stability after the anterior tube buttres

3. FADIGA EM ESTRUTURAS METÁLICAS TUBULARES SOLDADAS
Circular and rectangular hollow sections are used extensively in the field of the construction and mechanical engineering in all types of structures, such as offshore platforms, towers of communication, fluid conductors, bridges, footbridges and others, under different types of loading. These structures when submitted to cyclical loads, although in situation

4. Analysis of the dynamic behavior of the connectors formed by bonded-in steel rods for log-concrete composite deck bridges / Análise do comportamento dinâmico da ligação formada por barras de aço coladas para tabuleiros mistos de madeira e concreto para pontes
Neste trabalho avaliou-se o comportamento estrutural do sistema misto madeira-concreto para tabuleiros de pontes, com ênfase na análise dinâmica dos conectores de cisalhamento, para dois tipos de conectores: "vertical" e em "X". Foram efetuadas duas principais abordagens, numérica e experimental, além de um amplo levantamento teórico sobre o tema com b

5. Failure analysis of the polymeric external layer of the umbilical cables. / Análise de falha da camada polimérica externa de cabos umbilicais.
In the present work is proposed a method to establish a failure criterion of the polymeric external layer of umbilical cables used in offshore operations. The proposed method is based on the determination of the increment of the quantity of absorbed water by the polymeric external layer of the cable due to deterioration caused by cyclic loads and the aging p

6. Dynamic response of a UASB reactor submitted to organic and hydraulic cyclical loads: mathematical models and experimental results / Resposta dinâmica de reator UASB em escala piloto submetido a cargas orgânicas e hidráulicas cíclicas: modelos matemáticos e resultados experimentais
Poucos estudos são reportados na literatura sobre o comportamento dinâmico do reator UASB submetido a variações cíclicas diárias, de cargas orgânicas e hidráulicas, em períodos curtos de duração - iguais ou menores que 24h, com os quais verifica-se queda na eficiência do reator, causada pela provável flotação dos grânulos, problemas com gera�

7. Projeto, ConstruÃÃo e ValidaÃÃo de um Sistema de CompressÃo Uniaxial para Estimativa da CompactaÃÃo do Solo
The compaction of the agricultural soils has worldwide importance because of the increasing of the farm with machinery resulting in the increasing of heavy machines for cultivation system, mainly, in the developed countries. The term, soils compaction refers to the compression carried out on the non-saturated soil, during which an increase of bulk density ex
