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...
the nutritive values of non- processed and processed grape pomace with neurospora sitophila were evaluated. the chemical compositions and physical characteristics of samples were evaluated by laboratory analysis. an in vitro digestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (domd) to estimate ...
Abstract: Effect of different salinity levels (0, 50, 100, 150 and 200 mM NaCl) on photosynthetic characteristics and yield of two forage millet cultivars (Nutrifeed and Bastan) were investigated at this experiment. A factorial test based on randomized complete block design was conducted during 2010-2011 growing season in three replica-tions. The results showed that with increasing sal...
the ion_ osmoregulation and salinity tolerance capabilities of juvenile acipenser persicus of different age and size groups with 90 fry for each treatment in freshwater (fw :< 0.5 ‰), estuary water (ew: 9.5 ‰) and the caspian sea water (csw: 12.5 ‰) were investigated. the fishes are directly transferred from fw to ew and csw. the possible repercussions of ion_osmoregulatory processes on some cl...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...

This experiment was carried out to study the effects of Lactic Acid Bacteria (LAB) and urea on chemical composition, nutritive value and rumen fermentation characteristics of whole-crop barley. In a completely randomized design with cross over arrangement, 4 Suffolk male lambs were used. Whole-crop barley was either treated with LAB solution (35% dry matter) at the rate of 2 L/ton herbage fresh...

Field measurements of chlorophyll-a (Chl), phycoerythrin (PE), chromophoric dissolved organic matter (CDOM), and variable fluorescence (F(v)/F(m)) in diverse waters of the California Current, Mediterranean Sea and Gulf of Mexico using 375, 405, 510 and 532 nm laser excitation wavelengths (EW) are analyzed. EW = 375 and 405 nm were found more suitable for Chl assessment in high-Chl (> 10 μg/l) w...
Sewage sludge and effluents, as cheap sources of irrigation water and fertilizer, can supply plants with water and nutrients however, contamination of these sources with heavy metals and the possibility of human food chain contamination using these sources should be considered. In this research, the effects of industrial sewage sludge and effluents on concentration of some nurtients, heavy meta...
