AlfB and AlfC α-l-fucosidases from Lactobacillus casei were used in transglycosylation reactions, and they showed high efficiency in synthesizing fucosyldisaccharides. AlfB and AlfC activities exclusively produced fucosyl-α-1,3-N-acetylglucosamine and fucosyl-α-1,6-N-acetylglucosamine, respectively. The reaction kinetics showed that AlfB can convert 23% p-nitrophenyl-α-l-fucopyranoside into fuc...

کنترل تولید متناسب با تغییرات بار از مهمترین وظایف سیستم­های قدرت بمنظور بهره­برداری ایمن از واحد­های نیروگاهی می­باشد. به همین دلیل سیستم کنترل بار-فرکانس در واحدهای نیروگاهی یکی از مهمترین بخش­های نیروگاه محسوب می­گردد. این سیستم تحت عنوان سیستم کنترل اتوماتیک بار فرکانس شناخته می­شود.اگر چه در مطالعات مرتبط با سیستم­های قدرت به تغییرپذیری توان تولیدی توربین­های نیروگاهی در اثر تغییر سرعت اشا...

UNLABELLED We have studied the mechanism(s) of hyperlipidemia and liver insulin sensitivity in a rat model of severe chronic uremia (U). Basal lipid synthesis was decreased in freshly isolated hepatocytes from U when compared with sham-operated ad lib.-fed controls (alfC). Basal lipid synthesis in pair-fed controls (pfC) was in between U and alfC. Similarly, the activity of liver acetyl CoA car...

Renewable energy demand keeps increasing each day due its significances over the conventional sources of energy, particularly in this era where world is faced with many challenges related to clean energy. Among Energy Resources (RERs), wind has proven be cheaper and readily available. However, it intermittent nature therefore affecting voltage frequency stability microgrid systems, especially o...

The present work has taken a challenge to design model predictive controller (MPC) for automatic load frequency control (ALFC) of two-area, wind-integrated thermal power system equipped with battery energy storage (BESS) and demand response (DR) regulation task. Primarily, the incremental BESS employs new state charge (SOC)-based strategy regulate from saving life. Then, DR, along SOC-based BES...

The Major Depressive Disorder has been a burden of medical expense in Taiwan as well as the situation around the world. Major Depressive Disorder can be defined into different categories by previous human activities. According to machine learning, we can classify emotion in correct textual language in advance. It can help medical diagnosis to recognize the variance in Major Depressive Disorder ...

The main objectives of Load Frequency Control (LFC) are to hold the frequency constant ( Δf = 0) against any load change, each area must contribute to absorb any load change such that frequency does not deviate, each area must maintain the tie-line power flow to its pre-specified value. In LFC there are two major loops. Automatic Voltage Regulator (AVR) and Automatic Load Frequency Control (ALF...

Maintaining desired megawatt output of a generator unit is an essential role of Automatic Load-Frequency Control (ALFC) loop for secure operation of power system. In modeling this control loop, a major part concerns with the modeling of the mechanical behavior of turbine-generator. While, the efficiency of turbines normally depends on the speed they are operated, in most studies it is not inclu...
