A compact 2-DOF (two degrees of freedom) piezoelectric-driven platform for 3D cellular bio-assembly systems has been proposed based on “Z-shaped” flexure hinges. Multiple linear motions with high resolution both in x and y directions are achieved. The “Z-shaped” flexure hinges and the parallel-six-connecting-rods structure are utilized to obtain the lowest working stress while compared with oth...

AV In the analysis of the Cancer and Leukemia Group B (CALGB)/SWOG 80405 trial that we presented at the 2016 annual meeting of the American Society of Clinical Oncology (ASCO), we defined right-sided colon cancer as cancer of the cecum and the ascending colon up to the hepatic flexure. Left-sided colon cancer comprises cancer of the splenic flexure and cancer in regions distal to the splenic fl...

Duodeno-jejunal flexure injury is well recognised in blunt abdominal trauma generally. It is usually caused by compression of the relatively fixed bowel against the spine producing a shearing force which tears the bowel.1 Non-accidental injury is a rare cause of duodeno-jejunal flexure injury in childhood, but serious complications can ensue if there is a delay in diagnosis, which unfortunately...

We report a rare case of late staple-line recurrence arising 10 years after functional end-to-end anastomosis for splenic flexure colon cancer. An 80-year-old man, who underwent partial colectomy with functional end-to-end anastomosis for splenic flexure colon cancer 10 years earlier, presented with a chief complaint of anorexia. Complete blood count showed anemia, and the fecal occult blood te...

purpose: the purpose of this research was to determine the prevalence of mandibular first premolar teeth with 2 canals in the population of kerman. methods & materials: a total of 280 extracted first premolar teeth were collected from several health service centers within the province of kerman.extracted teeth were stored in 10% formalin containers. each tooth was initially cleaned with water a...

introduction: reconstruction of the oral cavity witha flap design containing the buccal mucosa and buccinator muscle but excluding the facial artery and vein is the topic of these case reports. case reports: this article uses random pattern vertically oriented partial thickness buccinator myomucosal flap for intraoral reconstruction in two cases. the first was for lining the mandibular anterior...

This article presents the analysis of experimental values regarding cracking pattern, specific strains and deformability for reinforced high strength concrete beams. The beams have the concrete class C80/95 and a longitudinal reinforcement ratio of 2.01%, respectively 3.39%. The elements were subjected to flexure under static short-term and long-term loading. The experimental values are compare...

in this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. the results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. the...
