Genetic diversity of Mycobacterium tuberculosis isolates from Tochigi prefecture, a local region of Japan

BACKGROUND Foreign-born patients with tuberculosis (TB) may introduce globally disseminated isolates of Mycobacterium tuberculosis into large cities in Japan. The risk of dissemination of these isolates into local regions, however, has not been determined. This study analyzed the molecular epidemiology of M. tuberculosis isolates obtained from TB patients living in a local region of Japan. ME...

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...

Refined Paleomagnetic Direction of the Miocene Motegi Formation, Tochigi Prefecture, Central Honshu

To refine the early Middle Miocene (ca. 16 Ma) paleomagnetic direction in the Motegi area, we collected paleomagnetic samples from dacite domes and intrusives of the Motegi Formation. Characteristic remanent magnetization components were revealed by stepwise demagnetization, which were used to calculate site-mean directions for 10 sites. Together with published data from 11 andesite and basalt ...

Influence of climate, elevation, and land use in regional herpetofaunal distribution in Tochigi Prefecture, Japan

Understanding the relationship between the distribution of organisms and their environment is important for regional conservation planning. While most herpetofaunal community studies address environmental influence on species richness, few studies describe environmental influence on species composition at geographic scales. Field surveys of herpetofauna were conducted during 1994-2000 in Tochig...
