in this study, the adsorption of thallium (iii) ion from aqueous solutions onto modified znonanopowder as a fairly low cost adsorbent has been investigated in batch mode. it was found thatmodification of the adsorbent was essential for obtaining the significant adsorption percentage. theadsorbent modified by sodium phosphate solution. the effect of experimental parameters such asinitial ph of s...

in this study formation and properties of o/w emulsion stabilized by a mixture of sodium caseinate (2, 5 and 10 wt %) and non-ionic emulsifier tween 80, sorbitan mono-9-octadecenoate, (0, 0.5, 1 and 1.5 wt %) were investigated at various ph values(3, 5 and 7) and calcium ion concentrations (0, 0.2, 0.4 and 0.6 wt%). emulsion samples were prepared by using a sonicator with a nominal power output...

-Most algor i thms in 3D computer vision rely on the pinhole camera model because of its simplicity, whereas virtually all imaging devices int roduce certain amoun t of nonlinear distort ion, where the radial dis tor t ion is the most severe part. Common approach to radial dis tor t ion is by the means of polynomial approximat ion, which introduces distortion-specific pa ramete rs into the came...

Establishment of great industrial centers and ports along the Khur-Musa Estuary in Mahshahr Port (Khuzestan, Iran) have been discharged a high volume of industrial and non-industrial pollutants to this estuary. The most important pollutants in Khur-Musa include industrial wastes and effluents including ammonia and urea units. This research aimed to survey the qualitative parameters of effluent ...

Electron String Ion Source (ESIS) “Krion-2” (JINR) is the first and now only ion source of such type in the world. ESIS is a sophisticated modification of Electron Beam Ion Source (EBIS) working in a reflex mode of operation under very specific conditions. Using the results of the research and the technology development the following main results were achieved in JINR with Krion-2 ESIS during r...

objective: intra-peritoneal administration of riluzole has been shown to preserve the membrane properties and firing characteristics of purkinje neurons in a rat model of cerebellar ataxia induced by 3-acetylpyridine (3-ap). however, the exact mechanism(s) by which riluzole restores the normal electrophysiological properties of purkinje neurons is not completely understood. changes in the condu...
