needle insertion is a minimally invasive technique in diagnosing and treating tumors. however, to perform a surgery accurately, the tissue should have minimum amount of displacement during needle insertion so that it reaches the target tissue. therefore, the tissue membrane has to move less to decrease rupturing under the membrane. in this study, the effect of different design parameters on dis...

in order to investigate the effects of drought stress and nitrogen fertilizer on photosynthesis rate and some physiological characteristics in two barley cultivars, a pot experiment was conducted using a randomized complete block design as a factorial experiment with three factors including water stress, nitrogen fertilizer and barley cultivars in three replications. irrigation treatments condu...
