Flow Reversal and Pressure pulsation: Innovative technique to enhance flux in Nanofiltration
Abstract: Reduction in Permeate flux with the period of time is the major drawback for the Pressure-driven membrane processes. Concentration polarization and membrane fouling are the two major limitations for the Pressure-driven membrane filtration processes. They lead to the severe flux decline and that need to be controlled for the better process efficiency. The resistance determination provides basis for selection of membrane and appropriate pressure –driven separation process. This paper outlines …

Fluconazole Resistance among Candida species Causing Vulvovaginitis
Abstract: Yeasts have emerged as a prominent cause of vaginal infections in community and hospitalized patients. Majority of cases of Vulvovaginal candidiasis (VVC) are caused by Candida albicans however, episodes due to non-albicans Candida appear to be increasing in the recent years leading to increase medical concern. Most non-albicans Candida species have higher minimum-inhibitory concentration (MIC) to fluconazole and infections caused by these species are often difficult to treat. This study …
