Viscosity measurements of subliquidus magmas: Alkali olivine basalt from the Higashi-Matsuura district, Southwest Japan
We carried out viscosity measurements and sampling of a crystal suspension derived from alkali olivine basalt from the Matsuura district, SW Japan, at subliquidus temperatures from 1230 °C to 1140 °C under 1 atm with NNO oxygen buffered conditions. Viscosity increased from 31 to 1235 Pa s with a decrease in temperature from 1230 to 1140 °C. On cooling, olivine first appeared at 1210 °C, followe...

متن کاملAneurysmal subarachnoid hemorrhage in Izumo City and Shimane Prefecture of Japan. Seasonal variation.
During the five year period from 1980 to 1984, 83 patients with aneurysmal subarachnoid hemorrhage (SAH) were hospitalized in Izumo City and 548 patients in Shimane Prefecture. The seasonal variation in the onset of aneurysmal SAH in both areas was investigated. The number of patients with aneurysmal SAH was great in January, May, October and December, while small in April, June and July. No as...
متن کاملEpidemiological study of Japanese spotted fever and tsutsugamushi disease in Shimane Prefecture, Japan.
Japanese spotted fever and tsutugamushi disease are tickborne infections that persist in Shimane Prefecture. Their respective causative agents are Rickettsia japonica and Orientia tsutsugamushi. We report here their outbreak characteristics. Since the first report in 1987 (1), Japanese spotted fever has been reported every year, totaling 80 cases at the end of 2005 (Fig. 1). Among 80 cases, it ...
