The heteroepitaxial growth of YBa/sub 2/Cu/sub 3/O/sub x/(YBCO)/CaF/sub 2/ has been studied and this structure has been applied to tunnel junctions. The CaF/sub 2/ thin film were epitaxially grown with [111] orientation on YBCO[110] films. The tunnel

Powder-metallurgy processed Nb/sub 3/Sn conductors were fabricated using a (Cu-1 or 3 wt.% Mn)-22.5 wt.%Nb composite. Plasma rotating electrode processed powders were used to improve workability. The Mn addition to the matrix increased the critical c

Epitaxial YBa/sub 2/Cu/sub 3/O/sub 7-x/ films were grown in situ by reactive coevaporation using a triple-hearth electron-beam gun system, in which a single electron beam is scanned over constituent metal sources. Superconducting properties were impr

Mutagenicity of cigarette smoke condensate (CSC) and the acidic, basic and neutral fractions of CSC was examined in the AL hybrid cell, a Chinese hamster ovary cell containing one human chromosome 11. Since the human chromosome 11 is not necessary fo

Gastric cancer incidence in men is almost double that in women. We investigated mucosal responses in the stomach against Helicobacter pylori (H. pylori) infections to elucidate the interindividual or sex-related differences, which may in turn be asso

The prevalence of Helicobacter pylori infection is high among Asian populations, but the incidences of gastric cancer differ greatly among northern and southern Asian populations. Here, we studied histopathological findings in stomach tissue using an
