free surface sloshing of liquid in a rectangular tank induced by lateral excitation has been studied numericallyand experimentally in this paper. the numerical simulation is carried out based on the volume of fluid (vof) method that provides free surface extraction in such problem. a tank with transparent walls is used to free surface tracking in experimental study while the movement amplitude ...

Introduction: In the current study, protective effect of natural honey applied during ischemia/reperfusion (I/R) was studied on infarct size in ischemic heartheart. Methods: Ischemic hearthearts (n=8 per group) were mounted on a Langendorff apparatus at constant pressure then subjected to 30 min regional ischemia followed by 120 min reperfusion. In control group, the hearts were perfused by ...

Study in surface water quality is important. Rivers are one of the main sources of water supply fordrinking, agriculture and industry. Unfortunately, sometime Rivers where wastewater dischargesare considered. For this reason,the pollutant transmission in river is one of the most importantproblems in Environmental Engineering. the Advection Dispersion Equation (ADE) is governedon the pollutant t...

The present article reports on the application of modified organo nanoclay as a green, easily prepared and stable solid sorbent for the preconcentration of trace cobalt ion in aqueous solution. The organo nanoclay was modified by adsorption of 5-(4-dimethyl amino-benzylidene) rhodanin reagent onto it. The sorption of Co2+ ions was quantitative in the pH range of 7.0 to 8.5, whereas quantitative...

Powder activated carbon surface (AC) was grinded and modified and altered procedure thorough a facile and easy chemical reaction to appearance of 2-((3silylpropylimino)1-methyl) phenol (AC- (SPIMP)). Subsequently, this novel sorbent efficiently applied for the extraction and preconcentration of some metal ions from real samples. Preliminary the influences of variables such as pH, amounts of rea...

the growth rate of stem cells in mobius cellready 3l bioreactor has been studied using comsol multi-physics simulation software in order to find out the best operational parameters for secure cell growth. the bioreactor geometry was defined according to the emd millipore issued information while turbulent and unsteady state solid-liquid 2-phase fluid flow equations were used for modelling the b...
