Conventional boost converters with bridge rectifier configuration are inefficient due to limited voltage step-up ratio which may not be applicable for high step-up applications as in the case of micro generators. The proposed IBS topology is based on the common part sharing method capable of operating both for positive and negative half cycle of the input signal. Result and simulation were conducted using PSIM environment. The proposed AC-DC IBS topology eliminates the requirement of bridge rectifier achieving high efficiency (about 99%), improved power factor (0.75, leading) and lower THD (about 38.8%) which is within IEEE standard.展开更多

Although its etiology and pathophysiology are complex and still not completely understood, aberrations along the microbe-gut-brain axis are known to play a central role. IBS is characterized by interrelated alterations in intestinal barrier function, gut microbe composition, immune activation, afferent sensory signaling and brain activity. Pharmaceutical treatment is generally ineffective and, hence, most therapeutic strategies are based on non-drug approaches. A promising option is the administration of probiotics, in which lactic acid bacteria strains are considered specifically beneficial. This review aims to provide a concise, although comprehensive, overview of the role of lactic acid bacteria in the pathophysiology and treatment of IBS.展开更多
