asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
Background and Objectives: Preparation and evaluation of nanocomposite films have become prevalent in recent years. One of the most important methods for dispersing nanoparticles in polymers is the use of ultrasound radiation. Polyvinyl alcohol-montmorillonite (PVA-MMT) nanocomposite films were prepared via solvent casting method. Materials and Methods: The effects of different ultrasound ti...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...

abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
Color and sensory characteristics have a key effect on consumerchr('39')s preferences of fish product. Hence, the aim of present study was to explore the effects of two stunning/slaughtering methods including electroshock and asphyxia in the air on color and sensory characteristics of cultured silver carp. The results showed all color indices changed significantly across both treatments at the ...
BACKGROUND AND OBJECTIVES Objective methods to assess quantitatively port wine stain (PWS) blanching in response to laser therapy are needed to improve laser therapeutic outcome. Previous studies have attempted to assess objectively PWS color based on point measurement devices. To date, these approaches have typically been limited by a number of factors such as small test area and need for cont...
