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...
this study gives a rough notional method to find their textual placing and valuating in the text, narrows the board of vision to mystic items and finally lists the strategies used by the translators of mathnawi to present solutions for preserving the additional values. at last, as the sum-up, strategies in comparison would be presented. it should be noted that by extending the translations from...
effect of sucrose replacement with date syrup powder on physiochemical properties of sponge cake such as specific gravity, volume, apparent density, solid density, porosity, symmetry, moisture content, water activity, crust color and textural firmness was studied. batter specific gravity of the control sample was higher than that of other samples. sucrose replacement with 100% of date syrup pow...
In this research according to unique properties of fused silica and Its numerous applications fused silica parts with 77% by weight solid loading formed by gel casting. Rheological behavior of the slurry and sintering conditions were optimized. Sample sintered at optimum conditions has bulk density of 1.71 g/cm3, open porosity of 18.13%, water absorption of 10.60%, linear shrinkage after firi...
In this paper, β-PbO nanoparticles were prepared by microwave irradiation. Then, the PbO nanoparticles with size of 32 nm were doped in the Bi2-xPbxSr2Ca2Cu4Oy superconductor with x = 0.0, 0.2, 0.4 and 0.6. The samples were synthesized by the standard solid state reaction method. The structural properties, microstructure and morphology of the samples have been studied by XRD and SEM. After synt...
We examined the effects of intracerebroventricular (i.c.v.) administration of adrenomedullin 2 (AM2) on plasma oxytocin (OXT) and arginine vasopressin (AVP) levels in conscious rats. Plasma OXT levels were markedly increased 5 min after i.c.v. administration of AM2 (1 nmol/rat) compared with vehicle and remained elevated in samples taken at 10, 15, 30, and 60 min. By contrast, plasma AVP levels...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Output characteristics of fuel cells are affected by a large number of parameters such as geometry, dimensions, construction materials and conditions of supplying fluids. In this paper a mathematical model followed by a two-dimensional numerical approach has been presented to study the fuel cell parametrically. Effect of oxygen concentration at gas diffusion layer entrance, temperature and ...
In this paper Sb2O3 nanoparticles are synthesized by solution method. The effect of these nanoparticles on the Bi-2223 superconductor properties has been investigated. The critical temperature, critical current density and activation energy were measured by the standard four-probe method. Magnetic properties of the samples were measured by using the AC magnetic susceptibility. The microstructur...
