This numerical study was conducted to simulate and analyze the pushout test for new shear connector in a steel-concrete composite system. In this system, stirrups of reinforced concrete beam are used as connectors when passed through holes drilled web inverted steel T-section. The analysis performed by creating three-dimensional finite element model using program ANSYS 21 student version behavi...

It was established at the beginning of 21st century that critical resolved shear stress small-sized (diameter from 50 nm to $10\text{ }\text{ }\ensuremath{\mu}m$) metallic crystals fabricated bulk increases drastically with decreasing specimen diameter. Dou and Derby [Scr. Mater. 61, 524 (2009)] showed that, stresses single various fcc metals obeyed a universal power law size an exponent $\ensu...

BACKGROUND Circumferential mucosal incision around a lesion is effective for reliable endoscopic mucosal resection. However, mucosal incision with a needle knife is difficult, even with submucosal injection of normal saline solution. To make needle-knife incision easier and safer, sodium hyaluronate has been used rather than normal saline solution. The aim of this study was to evaluate the clin...

Persistent left superior vena cava (PLSVC) is the most common congenital malformation of thoracic venous return and is present in 0.3 to 0.5% of individuals in the general population. This heart specimen was dissected from a 35-year-old male cadaver whose cause of death was determined as non-cardiac. The heart was examined and we found a PLSVC draining into the coronary sinus. The right superio...

OBJECTIVE Left atrium (LA) and left atrial pulmonary venous anatomy have clinical importance for atrial fibrillation (AF) and cardiac tumor surgery. A detailed anatomic knowledge of these structures may faciliate clinical evaluations. The aim of this study was to assess LA size and to demonstrate other anatomic features of LA with pulmonary vein openings in normal population. METHODS This des...

Studies dealing with the number or size of individual adipose cells in abnormal human bone marrow are lacking. To ascertain whether variations in fat tissue fraction depend on the size of individual adipocytes or their number or both, a stereologic study of 30 human bone marrow specimens (10 with aplasia, 10 with hyperplasia, and 10 with dysplasia) was performed. A total of 23,435 adipocyte pro...
