A soap-water enema was given without effect. A dorsal slit was made and the meatus was exposed. A rubber catheter proving ineffective, a small-sized metal catheter was passed very slowly and carefully and an ordinary kidney tray full of urine was drawn off very slowly. Multiple incisions on the scrotum, penis and perineum were then made, and the catheter tied up. Turpentine stupes to the abdome...

The objectives of this work were estimate the reaction rates of hydrolysis of carbosulfan to carbofuran and subsequent degradation of this last compound in irrigated rice fields, and the respective half life, in aquatic environment and soil solution, by mean of numerical solution of differential ordinary linear equations system that describes the kinetics of insecticide concentrations. The resu...

Ordinary water ice forms under ambient conditions and has two polytypes, hexagonal ice (Ih) and cubic ice (Ic). From a careful comparison of proton ordering arrangements in Ih and Ic using periodic density functional theory (DFT) and diffusion Monte Carlo (DMC) approaches, we find that the most stable arrangement of water molecules in cubic ice is isoenergetic with that of the proton ordered fo...

Steady, Darcian, 1-D, 1-phase evaporation through a vertically inhomogeneous soil from a horizontal water table is simulated as an optimal control problem, i.e. the hydraulic properties of the porous medium (relative permeability of moisture and capillary water retention curve) are considered as control functions. The Richards nonlinear ordinary differential equation is integrated twice as a bo...

water quality zoning have been recognized as a useful tool, which gives managers a sweeping view for taking environmental conservative actionsin oeder of priority. ordinary methods, which have been used in iran, involve some defections such as disregard water usage, uncertainty due to sampling error and classification, and changing the class number due to a bit change in water quality parameter...

In slope engineering, soils are commonly at unsaturated state. The question of how to apply unsaturated soil mechanics theory to the slope stability analysis has become a hot spot in today’s geotechnical engineering research. Based on the experimental research of how shear strength of residual soil varies with water content, reasonable computation modules can be created. By using limit equilibr...
