field experiments were conducted on an existing subsurface drainage system in roodasht region of esfahan, ian, to test the performance of drain spacing equations for transient flow. the water table profiles recorded from a series of observation wells indicated an essentially flat water surface. the effective hydraulic conductivity and the degree of anisotropy were calculated as 19.2 cm h-1 and ...

In this paper, the long-range Van Der Walls dispersion force correction (vdW-DF) for a combined system consisting of an Ag-chain adsorbed on a monolayer of graphene is studied. Calculations are based on density functional theory (DFT) performed by using various LDA, PBE and BLYP approximations. Since Ag chain is weakly adsorbed on graphene sheet, the Van Der Waals contribution to the total adso...

In the last three quarters of the fifteenth century Spain, like the rest of Europe, was under the spell of Flemish art. The realism of the north had a strong appeal to Spanish taste, and the technical discoveries of Flemish painting and the new iconographies from Flanders and Germany were enthusiastically received. In the second half of the century in particular, tapestries, paintings, and scul...
