In this paper, topology optimization (TO) is applied to determine the form, size and location of holes for the special form of perforated steel plate shear wall (PSPSW). The proposed model is based on the recently presented particular form of PSPSW that is called the ring-shaped steel plate shear wall. The strain energy is selected as the objective function in the optimization. Simple Isotropic...

In this article, the role of nano-size calcium carbonate in penetration resistance of medium- density polyethylene (PE) was investigated through experiments. In order to study the penetration resistance of PE and its nanocomposites, perforation test was carried out. The results of tests showed that penetration resistance depends strongly on calcium carbonate amount. As a matter of fact, additi...

Most patients with chronic duodenal ulcer disease have Helicobacter pylori infection and eradicating it considerably reduces the relapse rate. The prevalence of H pylori in 80 patients (mean age = 52 years, range 17-85) presenting with acute perforated duodenal ulcer was examined and compared with age and sex matched hospital control patients. H pylori state was assessed by serum anti-H pylori ...

A case of acute acalculous perforated cholecystitis with acute generalized peritonitis in a middle aged cachectic man, presenting late in a moribund condition, is reported. He underwent emergency laparotomy (subtotal cholecystectomy), went into multi-organ failure and was managed accordingly. The patient recovered in about 2 weeks and was followed-up regularly.

a more clinically relevant time frame. Methods and Results. We used a perforated balloon (Wolinsky) catheter to inject retroviral vectorcontaining virions into rabbit aortas in vivo. The virions were injected within 1 minute. Aortas were removed 5-14 days after injection and analyzed for evidence of gene transfer. In initial studies, nine rabbits were injected with a vector expressing the 3-gal...

Structural analysis of the High Zagros Zone and southwestern rim of the Sanandaj-Sirjan Zone in the Chaharmahal-va-Bakhtyari area resulted in recognition of a thrust system comprises the Ben, Hafshejan, Farsan, Kuhrang and Bazoft thrust sheets from NE to SW. In this study, quartz and calcite microstructures as well as fluid inclusions have been utilized to inspect deformation conditions of the ...

Background We previously conducted a first-in-human clinical study of articular cartilage repair using autologous chondrocyte sheets and confirmed the regeneration of hyaline-like cartilage in all eight patients. However, regenerative medicine with autologous chondrocyte sheets requires the harvesting of tissue from healthy regions, and the quality of this tissue varies between individuals. To ...
