in order to investigate the effect of silicon application on some physiological characteristics and growth of wheat (triticum aestivum l.) under late drought stress condition, an experiment was conducted at the agriculture and natural resources university of ramin, khuzestan during year 2012. the experiment was conducted in the open environment as factorial randomized complete block design with...
As a sequel to a recent work we consider the generalized stress concentration factor, a purely geometric property of a body that for the various loadings, indicates the ratio between the maximum of the optimal stress and maximum of the loading fields. The optimal stress concentration factor pertains to a stress field that satisfies the principle of virtual work and for which the stress concentr...
To evaluate the effect of copper nanoparticles on the characteristics of mallow under drought stress conditions, a factorial experiment was conducted in a completely randomized design with three replications under greenhouse conditions in 2017. The first factor of drought stress was at three levels without stress and 75 and 50% of field capacity and the second factor was copper nanoparticles at...
