Considering unsaturation conditions of soil significantly helps to produce relatively real results. Numerical methods have been assumed as conventional methods in soil mechanics to examine soil behavior. However, the accuracy of numerical methods dramatically depends on applying the appropriate behavioral model to solve problems. One of the known elastoplastic models for unsaturated soils i...

blackleg in cattle has been recognized since 1938 in iran that mostly affects cattle in enzootic farm. main object of this study was to prepare and formulate a concentrated potent vaccine for immunization of cattle against blackleg in iran. experimental concentrated blackleg vaccine was prepared according to the method described by fao. the medium (modified medium for production of experimental...

Previously, the author obtained an analytical solution for determining vertical displacements of homogeneous isotropic quarter-space face, which is affected by a concentrated force. This expression gave exact face made incompressible material and approximate Poisson ratio different from 0.5. Later, in published paper S. V. Bosakov P. D. Skachek “Action Concentrated Force on 1/8 Homogeneous Isot...

Theory suggests that the effects of disadvantaged neighborhoods on child educational outcomes may depend on a family’s economic resources as well as the timing of neighborhood exposures during the course of child development. However, most previous research assumes that disadvantaged neighborhoods have the same effects on all children regardless of their family resources, and few prior studies ...

Theory suggests that neighborhood effects depend not only on where individuals live today, but also on where they lived in the past. Previous research, however, usually measures neighborhood context only once and does not account for length of residence, thereby understating the detrimental effects of long-term neighborhood disadvantage. This study investigates effects of duration of exposure t...

A concentrated solution of purified enterokinase is conveniently prepared from the fluid contents of pigs' duodena by means of fractional precipitation with ammonium sulfate under the proper pH conditions.
