OBJECTIVE To radiographically evaluate the quality of cementation and implantation technique using a polished, triple-tapered femoral stem in total hip arthroplasty (THA). METHOD Retrospective study with radiographic evaluation of 86 hips in 83 patients who underwent to primary THA with the triple-tapered cemented femoral stem C-Stem (DePuy Orthopedics, Warsaw, Indiana). Cases with at least o...

In this study, three amorphous oxide thin films are prepared by an electron beam evaporation combined with ion-assisted deposition technique. With the aid of optical flux mapping method, film thickness distribution good uniformity can be obtained appropriate coating masks. Three metal single-layer SiO2, Ta2O5 and Nb2O5, respectively. These were deposited on a substrate holder radius 275 mm that...

Fine-blanking is a molding process based on the common blanking process, which obtains hydrostatic stress through blank holder reverse jacking, in order to increase material plasticity. It requires special equipment, namely fine-blanking press, complete process. In this paper, problem of speed slide block fluctuation found actual use 12,000 kN hydraulic press after multi-stage pressure source o...

Wrinkling, developed due to compressive instability, is one of the main failure modes in deep drawing processes. Depending on die geometry and blank holder force, it can be observed as flange wrinkling and/or side-wall wrinkling. In this study, cylindrical cup process investigated by using different constitutive models that are formed CPB06ex2, Hill’48, BBC2008-8p BBC2008-16p yield criteria wit...
