BACKGROUND The development of occupational asthma is the result of interactions between environmental factors and individual susceptibility. We assessed how our model of chemical-induced asthma is influenced by using different mouse strains. METHODOLOGY/PRINCIPAL FINDINGS On days 1 and 8, male mice of 7 different strains (BALB/c, BP/2, A/J, C57Bl/6, DBA/2, CBA and AKR) were dermally treated w...

It is numerically shown that the groundstate ofthe Friedel problem (consisting of a conduction band and a d­ resonance), occupied with (n+ I) electrons, can be written as If/ = (Aoo+Bd*) rr=1 o~Po, where ail represents a localized conduction electron state, d* is the Friedel resonance state and TI~=1 a7,po is a Slater determinant of n single electron states it7, (po is the vacuum state). The 07...

Incubation of photosynthetic reaction centers from Rhodobucter sphaeroides R26 with exogenous lY-OH-bacteriochlorophyll ar or aoo according to Scheer et al. (1987) results in the exchange of endogenous bacteriochlorophyll ar. The exchange amounts to 5 50% according to HPLC analysis, corresponding to a complete replacement of the ‘monomeric’ bacteriochlorophylls, Bu and Br, by exogenous pigment....

Implementing conservation measures for data-limited species is a fundamental challenge wildlife managers and policy-makers, proves difficult cryptic marine animals occurring in naturally low numbers across remote seascapes. There currently scant information on the abundance habitat preferences of Australian snubfin dolphins ( Orcaella heinsohni ) throughout much their geographical range, especi...

ارزیابی خشک‌سالی، ازنظر زمانی و مکانی، برای برنامه‌ریزی‌های کاهش خسارات در استان کردستان اهمیت بسیاری دارد. این تحقیق، از شاخص بارش استانداردشده همچنین، پوشش گیاهی بارزشدة استخراجی تصاویر ماهواره‌ای، به‌منزلة پارامتر تعیین‌کنندة استفاده شده است. به‌این‌منظور، داده‌های آماری ایستگاه‌های هواشناسی شامل حداکثر دمای ماهیانه، مجموع سالیانه نیز سنجندة مادیس به‌کار رفته با مقایسة پارامترهای میانگین سال...
