PURPOSE The proximal femur is one of the most common locations for benign bone tumors and tumor like conditions. We describe the clinical outcomes of the surgical treatment of benign lesions of the proximal femur including femoral neck using compression hip screw and synthetic bone graft. METHODS Thirteen patients with benign bone tumors or tumor like conditions of the proximal femur includin...

Pseudoelastic NiTi structural components have been shown to exhibit tension/compression asymmetry. Under tension, phase transformation induces localized strains of nearly 7% that spread under constant stress, while compression the leads hardening at significantly higher strain is smaller and grows homogeneously. Bending tubes ovalizes their cross-section, a nonlinearity reduces bending rigidity...

This paper presents a detailed investigation of the performance cold-formed round-ended concrete-filled steel tubular (RECFT) columns under cyclic loading via experimental and numerical approaches. Experimental tests observations this type novel composite column are presented, its failure modes, hysteretic curves, ductility ratio, energy dissipation, stiffness, strength degradation revealed. A ...

BACKGROUND/AIMS Local pancreatic resections can avoid the unnecessary resection of the normal pancreatic parenchyma in comparison with standard pancreatic resection. However, the incidence of pancreatic fistula after local pancreatic resection is high, and still responsible for most morbidity and mortality. METHODOLOGY We reviewed 6 patients who underwent intraoperative pancreatography using ...

In predictive coding a group of neighboring picture elements is used to select a suitable prediction value for a current pixel. In this paper, we propose two techniques for lossless images compression based on predictive coding. In the rst technique which called, the predictors, we replace each pixel in the image by the predicted pixel; we use various schemes to predict the value of a pixel. In...

Gap between the steel tube and core concrete of Concrete-Filled Steel Tube (CFST) members is regarded as an initial imperfection, which may exist in CFST arch bridge due to construction process problems. In this paper, based on design scheme bolt-welded joints rib columns extra-long span bridge, effects two types imperfections, interfacial gap spherical-cap gap, mechanical properties Bolt-Welde...
