The transport mechanism of contaminated groundwater has been a problematic issue for many decades, mainly due to the bad impact of the contaminants on the quality of the groundwater system. In this paper, the exact solution of two-dimensional advection-dispersion equation (ADE) is derived for a semi-infinite porous media with spatially dependent initial and uniform/flux boundary conditions. The...

in this paper, we use parametric form of fuzzy number and we converta fuzzy linear system to two linear system in crisp case. conditions for the existence of a minimal solution to $mtimes n$ fuzzy linear equation systems are derived and a numerical procedure for calculating the minimal solution is designed. numerical examples are presented to illustrate the proposed method.

solid solutions of ag-cu were prepared via ball milling process, for about 5-30 h. the cu-20at%ag and cu-3.64at%ag composition were investigated by x-ray diffraction technique. it was realized that the solid solubility level could be increased by increasing the initial solute content in the mixture. in addition, shifts in peak positions of silver and copper were observed with milling time. the ...

Hypertonic saline solutions (HSS) have several characteristics that may improve the survival of patients during the initial treatment of certain types of shock. The use of isotonic crystalloids for resuscitation has several limitations: large infusion volumes are needed to increase the intravascular space; these large volumes cannot be given rapidly; and the fluid rapidly redistributes througho...
