The importance of materials in modern world can be realized from the fact that much of the research is being done to apply new materials to different components. However it is natural for a design engineer to rely on trusted and tested materials, but now the world is changing .Today composite materials have changed all the material engineering. The evolution of composite materials has given an ...

In motors containing magnets, irreversible demagnetization failure is one of the factors that negatively affect motor performance. this study, traditional Axial Flux Permanent Magnet Synchronous Motor (AF-PMSM) rotor structure was changed and gained feature starting from line used. Line Start AF-PMSM with 5.5 kW shaft power has 4 poles each pole consists 5 magnets. Demagnetization obtained by f...

Introduction: Avulsion of the distal biceps tendon from the tuberosity occurs mostly in middle-aged males resulting from eccentric loading of the flexed, supinated forearm . When non-operative treatment is chosen, supination strength decreases by 50% and flexion strength is reduced by 35-40% . Surgical repair has been shown to be a better alternative than non-operative treatments for restoratio...

The authors investigated the prevalence and the difference in the severity of systemic complications following intramedullary nailing of bilateral tibial and femoral shaft fractures. A retrospective chart analysis of 12 consecutive patients with bilateral tibial shaft fractures (TF) and 14 patients with bilateral femoral shaft fractures (FF) was performed. The incidences of bilateral tibial fra...

Process cooling below ambient temperature is an energy demanding part of many chemical production processes. Compression refrigeration systems operating at very low temperatures consume a lot of high quality utility such as electricity or high pressure steam to drive the compressor units. In industrial process clusters with several processes operating at low temperatures, it is important to inv...

OBJECTIVES To review the primary and the final results of surgical management of ipsilateral femoral neck and shaft fractures. SUBJECTS AND METHODS Seventeen patients (2 female, 15 male, average age 37 years, range 20-60) with ipsilateral femoral neck and shaft fractures were treated by compression plate fixation for the femoral shaft fractures and dynamic hip screw or cannulated cancellous s...

The main goal of this research is to analyse the effect of angular velocity on stability and vibration of a simply supported Rayleigh rotating shaft. To this end, non-dimensional kinetic and potential energies are written while lateral vibration is considered. Finite element method is employed to discrete the formulations and Linear method is applied to analyse instability threshold of a rotati...

Background. Selection of entry point for nail insertion is controversial and lack firm anatomical basis. The study is done to analyze the proximal anthropometry of femur and measure the Trochanter-Shaft Angle to find its relation and significance in selection of entry point for antegrade uniplanar femoral nail. Materials and Methods. Study involves the measurement of trochanter-shaft angle and ...
