Membrane properties such as porosity and surface morphology significantly affect fouling in membrane bioreactors (MBRs). Amphiphilic Pluronic block–copolymers have attracted attention recent years their use during preparation has resulted improved properties. This study focused on establishing a technique to improve by adding TR–702 prepare chlorinated poly(vinyl chloride) (CPVC) flat–sheet sui...

Isotropic ultra-thin shells or membranes, as well cable–membrane structures, cannot resist loads at the initial state and always require a form-finding process to reach steady state. After this stage, they can work in pure membrane quickly experience large deflection behavior, even with small amplitude of load. This paper aims improve load-carrying capacity strength structures via exploiting ad...

BACKGROUND Preterm premature rupture of membranes (PPROM) is the largest identifiable cause of preterm birth. There is currently no good screening test for PPROM in low-risk asymptomatic patients. Our goal was to identify how imaging methods can be utilized for examining the risks for PPROM in asymptomatic patients. METHODS This paper is a systematic review of the literature on fetal membrane...

This study introduces the effect of the thickness of a bacterial cellulose membrane by comparing the bone regeneration effect on rat skulls when using a collagen membrane and different thicknesses of resorbable bacterial cellulose membranes for guided bone regeneration. Barrier membranes of 0.10 mm, 0.15 mm, and 0.20 mm in thickness were made using bacterial cellulose produced as microbial ferm...

OBJECTIVE To assess the visual and anatomical outcomes following idiopathic macular epiretinal membrane (IERM) surgery. STUDY DESIGN Case series. PLACE AND DURATION OF STUDY Layton Rehmatulla Benevolent Trust (L.R.B.T), Free Base Eye Hospital, Karachi, from January 2015 to June 2016. METHODOLOGY Thirty eyes of thirty patients affected with idiopathic macular epiretinal membrane stage 2 we...

Objective. Nanotechnology has the potential to improve hemodialysis membrane technology. Thus, a major objective is to understand how to enhance toxic solute fluxes across these membranes. The aim of this concept building study is to review the application of irreversible thermodynamic (IT) to solute fluxes. Methods. We expanded the application of the Nernst-Planck equation to include the Kedem...

PURPOSE The purpose of this study was to identify the possible alteration in the thickness of the epithelium basal membrane of the vocal cords and correlate it with the cause of death. METHOD Larynxes collected from adult autopsies during the period of 1993 to 2001 were utilized. We used the hematoxylin-eosin and periodic acid-Schiff staining methods for the morphological and morphometric ana...
