Because of the minimal soft tissue injury, the laparoscopic-assisted internal fixation is a promising technique in fixing the pelvic anterior ring fracture. The aim of this study was to investigate the biomechanical performance of the laparoscopic-assisted plate by the finite element method. Four kinds of implants were investigated, that is, the laparoscopic-assisted plate (LAP), the percutaneo...

1 Motivation 1.1 A goal : the numerical modeling of the guitar This work is concerned with sound synthesis, the goal of which is to reproduce numerically the sound of musical instruments. We are interested in the study of the guitar. In our model the soundboard is coupled to one or more strings by means of a bridge. The soundboard is itself coupled with an open air cavity and the outer air. The...

INTRODUCTION This study describes the results achieved using a combination of allogeneic mesenchymal stem cells (MSCs) with chondrocytes (CHC) and a new scaffold consisting of type-I collagen and chitosan nanofibers in the prevention of partial growth plate arrest after iatrogenic injury in pigs. MATERIAL AND METHODS The miniature pig was selected as an experimental model to compare the resul...

The epiphyseal plate is a hyaline cartilage plate that sits between the diaphysis and the epiphysis. The objective of this study was to determine the impact of an injury in the growth plate chondrocytes through the study of histological morphology, immunohistochemistry, histomorphometry and Western Blot analyses of the caspase-3 and cleaved PARP-1, and levels of the inflammatory cytokines, Inte...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...

This paper aims at introducing nonlinear interactions in the sound synthesis of resonators. Sound is performed using formalism Volterra series which used to describe and simulate weakly models their kernels. Interactions are constraints imposed considered excite (e.g. bowing a string or striking plate) connect resonators together (such as connecting bridge). requires resolve an inverse problem ...

Padma Multipurpose Bridge is situated on a section of the river where soil condition highly heterogeneous and intermixed with different layers, for which pile design was critical part. This paper describes properties ground profiling Bridge. Different types field laboratory tests were carried out to obtain accurate parameters profiles along whole alignment bridge. Standard Penetration Tests, Co...

BACKGROUND Decreasing the stiffness of locked plating constructs can promote natural fracture healing by controlled dynamization of the fracture. This biomechanical study compared the effect of 4 different stiffness reduction methods on interfragmentary motion by measuring axial motion and shear motion at the fracture site. METHODS Distal femur locking plates were applied to bridge a metadiap...

Based on the 16–32 m simply-supported beam bridge Shanghai-Kunming high-speed railway, a collision model of CRTS II track system was established. The considered longitudinal, horizontal as well vertical nonlinear constraints among structural layers, and Kelvin element used to simulate pounding effect gaps. seismic response firstly analyzed then influences different cases damaged plate, base mor...
