Accumulating evidence suggests that inflammatory mediators secreted by activated resident or infiltrated innate immune cells have a significant impact on the pathogenesis of neurodegenerative diseases. This may imply that patients affected by a neurodegenerative disease may benefit from treatment with selective inhibitors of innate immune activity. Here we review the therapeutic potential of ap...

MOSFET is the most commonly used devices in DC-DC power converters, and its performance is important to the prognosis and health management of power. The paper proposes a degradation analysis model for MOSFET in DC-DC power converters. A method for detecting the degradation of MOSFET is also introduced. Simulations have shown that the method can predict deterioration in the performance of MOSFE...

The thermoelectric transfer difference of Thermal Converters (TCs) can be evaluated in both current mode and voltage mode, using a fast-reversed dc (FRDC) source. Some types of TCs show differences in the thermoelectric transfer difference between voltage and current mode as large as some parts in 10. In order to investigate the origin of the discrepancy, the change of the thermoelectric transf...
The roles of low-molecular-weight thiols (LMWTs), such as glutathione and phytochelatins, in arsenic (As) tolerance and hyperaccumulation in Pteris vittata an As-hyperaccumulator fern remain to be better understood. This study aimed to thoroughly characterize LMWT synthesis in P. vittata to understand the roles played by LMWTs in As tolerance and hyperaccumulation. LMWT synthesis in P. vittata ...
امروزه توجه به افزایش گازهای گلخانه ای و آلودگی های ناشی ازسوخت های فسیلی منابع پاک تولید انرژی توجه به تولید انرژی پاک بیش از پیش شده است. پیل سوختی پلیمری یکی از انواع منابع تولید پراکنده می باشد که به دلیل کارایی قابل توجه، جایگاه ویژه ای پیدا کرده است. عموما از پیل های سوختی برای کاربردهای اتصال به شبکه و خودروی الکتریکی استفاده می شود. به منظور افزایش سطح ولتاژ خروجی پیل سوختی از یک مبدل d...
