Why and How Political Science Can Contribute to Public Health? Proposals for Collaborative Research Avenues

Written by a group of political science researchers, this commentary focuses on the contributions of political science to public health and proposes research avenues to increase those contributions. Despite progress, the links between researchers from these two fields develop only slowly. Divergences between the approach of political science to public policy and the expectations that public hea...

Plant science. How plant cells go to sleep for a long, long time.

S eeds are plant spores—desiccated, dormant cells in which metabolism and growth have been drastically slowed, so that the organism can wait out adverse conditions. This is especially important for plants, which cannot run away from environmental threats. Instead of motility, they use dormancy to outlast adversarial conditions caused by pathogens or severe weather. Indeed, some seeds remain via...

islanding detection methods for microgrids

امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
