Our previous research has shown that dynamic avalanche phenomenon is related to the hole trap level that is induced at an energy level of Ev+0.35 eV. In this study we will describe how we used the DLTS (deep level transient spectroscopy) method and CL (cathode luminescence) method to identify that the defects which form the hole trap level are in fact CiOi that is present in the Si wafer. We fabricated...
Abstract. Intestinal malrotation is rare in older children and adults. We performed laparoscopic repair and treatment for a 13-year-old girl diagnosed as having intestinal malrotation complicated by midgut volvulus. Under laparoscopic vision, the midgut volvulus was untwisted by grasping and pulling the intestine; Ladds band was divided and broadened; hepatic and splenic flexure of the colon was fixed;...

We performed laparoscopic repair and treatment for a 13-year-old girl diagnosed as having intestinal malrotation complicated by midgut volvulus. Under laparoscopic vision, the midgut volvulus was untwisted by grasping and pulling the intestine; Ladd's band was divided and broadened; hepatic and splenic flexure of the colon was fixed; and...
A series of activated carbon fibers (ACFs) produced from organometallics compounds such as Y(acac) 3 or Al(acac) 3 /pitch composites were characterized. The pore-size, surface state and graphitic crystallite size were examined by means of N 2 adsorption isotherm, X-ray photoelectron spectroscopy and X-ray diffraction (XRD) analysis. The presence of Y or Al increased the pore-size...
