In this study, a mechanical anchorage for prestressed carbon fiber–reinforced polymer (CFRP) rods was proposed. The proposed consisted of steel barrel with conical hole and three separate aluminum wedges that are in direct contact the CFRP rod. system relied only upon friction, without any adhesives required. static fatigue behaviors anchor were experimentally investigated according to European...

BACKGROUND In patients who have an injury of the cervical spinal cord, the brachioradialis tendon may be transferred to the extensor carpi radialis brevis tendon to restore voluntary wrist extension. We hypothesized that the active range of motion of the wrist depends on the position of the elbow after this transfer because the brachioradialis changes length substantially during elbow flexion, ...

The self-centring system presented in this paper is a novel damage control technique designed to improve the resilience of concentrically braced frames (CBF) under seismic action. Namely, traditional CBFs can undergo large residual drifts following an earthquake event which limit opportunity for cost-effective repair structure. Additionally, gusset plates connecting brace members beams and/or c...

Graphene deposited over a trench has been studied in the context of nanomechanical resonators, where experiments indicate adhesion of the graphene sheet to the trench boundary and sidewalls leads to self-tensioning; however, this adhesion is not well understood. We use molecular dynamics to simulate graphene deposited on a trench and study how adhesion to the sidewalls depends on substrate inte...

All-inside meniscal repair has become a popular technique. The number of meniscal repairs done in the United States has increased dramatically since the introduction of the Meniscal Arrow (Linvatec Corp, Largo, FL). Although these devices are easy to use, there have been several compliations reported with their use. Newer devices (Mitek RapidLoc and Smith and Nephew Fas-T-Fix) allow tensioning ...

Soft-tissue balancing during total knee arthroplasty is an important step in optimizing the mechanical balance of the knee joint. Soft-tissue contractures that result from varus coronal plane deformity can pose a difficult problem, and the surgeon should have a standard procedure for managing such situations in the operating room. Balance may be assessed intraoperatively with the use of spacer ...
