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 ...

Organic Farming: Challenge of Timing Nitrogen Availability to Crop Nitrogen Requirements

being an environment friendly and more sustainable farming system. Ironically, scientists one-half century Groundwater has become increasingly degraded by NO3, and this ago devoted much research emphasis to providing farmdegradation has been partially attributed to the use of commercial inorganic N fertilizers. Conversion from conventional fertilizer maners information on the beneficial use of ...

A Review of Laboratory Methods for Measuring Oxidative Stress

Introduction: Antioxidant defense system, including enzymatic and non-enzymatic antioxidants, protects cells from oxidative damage by neutralizing oxidant compounds. Increasing the production of oxidant species and decrease activity of antioxidant system causes oxidative stress. The role of oxidative stress in the pathogenesis of human diseases and strengthening of human antioxidant defense sys...
