the mechanism and the parameters affecting the matrix-fibril morphology in melt spun polyblend fibers are discussed. the properties of polymeric blends depend considerably on their final morphologies. blending of two miscible polymers, normally gives rise to formation of a single-phase morphology while blending of two immiscible polymers can create a two or three (in case of using compatibilize...
Pectoralis major ruptures occur in large, muscular individuals, and repair constructs may experience significant tension. Four different suture techniques were evaluated biomechanically to determine the effect of suture technique on optimizing fixation strength. Forty fresh-frozen cadaveric shoulders were repaired using endosteal buttons. The control group was repaired with #2 polyblend suture ...
The thermoluminescence (TL) glow curves of UV irradiated PAAm-PVA polyblend have been studied. The experimental glow curves show the presence of two peaks with glow peak temperatures at 373K and 479K. The values of activation energy and frequency factors are determined by employing computer simulation. Most of the TL glow curves obey non first order kinetics. The results obtained by using TL ex...
Femur fractures occur during broaching and impaction of the implant during hip arthroplasty. Prophylactic cerclage of the proximal femur with braided cable and steel wire has been shown to decrease hoop stresses and has been posited as a way to decrease the incidence of intraoperative fracture. In this biomechanical study, the authors investigated the strain across the proximal femur during bro...
