Over the past two decades, membrane processes have gained a lot of attention for the separation of gases. They have been found to be very suitable for wide scale applications owing to their reasonable cost, good selectivity and easily engineered modules. This critical review primarily focuses on the various aspects of membrane processes related to the separation of biogas, more in specific CO(2...

BACKGROUND The objective of this study was to compare total costs of care and its major components for community-living patients with Alzheimer's disease (AD) or dementia with Lewy bodies (DLB). This cross-sectional analysis of baseline data from the Predictors II Study took place in three university-based AD centers in the U.S. METHODS Community-living patients clinically diagnosed with prob...

Abstract The dry half of the year from May to October over Maritime Continent (MC) has experienced unprecedented damages forest fires in recent decades. observed interannual rainfall variability during this period is closely tied sea surface temperature (SST) equatorial Pacific (EP). Therefore, future evolution EP SST can be expected influence climatological precipitation MC. Whilst multi-model...

Abstract Carbon dioxide (CO 2 ) emissions have been the root cause for anthropogenic climate change. Decarbonisation strategies, particularly carbon capture and storage (CCS) are crucial mitigating risk of global warming. Among all current CO separation technologies, membrane has biggest potential CCS as it is inexpensive, highly efficient, simple to operate. Polymeric membranes preferred choic...

In this study, novel mixed matrix membranes (MMMs) were synthesised by adding metal organic frameworks (MOFs) (UiO-66 and UiO-66-NH 2 ) to pristine sulfonated polyethersulfone (PES). The differing synthetic method resulting in MMM where additives grafted the polymer, or formed a natural interface, allowing impact of these features be investigated. composite characterised FTIR, PXRD, water conta...

The basic aspects of the endogenous intoxication syndrome (EIS) in pathogenesis many diseases are still poorly understood - an increase content a wide variety compounds, most which belong to middle mass molecules (MMM) with 500-2000 D, under conditions metabolically associated steatosis liver (MASL) as initial stage fatty disease has not been yet established.
 In order determine average to...

سهم قابل توجهی از پژوهش‌های انجام شده در زمینه جداسازی گاز کربن دی‌اکسید (CO2)، به‌­عنوان مهم­‌ترین چالش در کنترل گازهای گلخانه‌ای، به توسعه غشاهای پلیمری جدید اختصاص یافته است. در این باره، غشاهای ماتریس ترکیبی (MMMs)، یعنی ترکیبی از ذرات جامد پراکنده شده در شبکه پیوسته پلیمر، به­‌عنوان راهکار مؤثری برای بهبود کارایی غشاهای پلیمری جداسازی گاز مطرح شده است. در این پژوهش، غشاهای ماتریس ترکیبی از...

Hemodialysis mainly removes small water-soluble uremic toxins but cannot effectively remove middle molecules and protein-bound toxins. Besides, the therapy is intermittent leading to fluctuating blood values fluid status which adversely impacts patients’ health. Prolonged hemodialysis (with adequate anticoagulation) could improve removal of development portable wearable artificial kidneys offer...

AIM While clinical endpoints provide important information on the efficacy of treatment in controlled conditions, they often are not relevant to decision makers trying to gauge the potential economic impact or value of new treatments. Therefore, it is often necessary to translate changes in cognition, function or behavior into changes in cost or other measures, which can be problematic if not c...

Metal–organic frameworks (MOFs) can respond in an anomalous way to external stimuli, giving rise dynamic bond rearrangement and/or large-amplitude structural transformations without breakage of the crystal.Their response triggers is tunable by modifying crystal size, defect engineering, and altering operating conditions.To design MOFs for targeted functional applications, a fundamental understa...
