in order to study drought tolerance indices and to introduce tolerant maize hybrids in drought conditions, an experiment was conducted at the experimental field of seed and plant improvement institute, in 2009. the experiment was carried out using split-plot in a randomized complete block design (crbd) with three replications. the main plots consisted of three levels of irrigation regimes (irri...
Objective: The purpose of this study was to examine the compare of perceived stress and feeling lonely in breast cancer patients and normal individuals. Methods: This research is causal-comparative. The population consist of all patients with breast cancer in hospitals of Ardebil. 60 patients and 60 normal individuals were selected with sampling method. The s...
Seismic moment and rupture length can be combined to infer stress drop, a key parameter for assessing earthquakes. In natural earthquakes, drops are largely depth-independent, which is surprising given the expected dependence of frictional on normal stresses hence overburden. We have developed transparent experimental fault that allows direct observation thousands slip events, with ruptures ful...
ornithine is a non-proteinogenic amino acid, which plays an essential role in the metabolism of plants. regard to the chirality of the molecule, physiological response of the plant cells to its two enantiomers have not been widely investigated yet. in the present study, suspension-cultured tobacco cells were treated with 1 mm of d- and lenantiomers of ornithine in normal conditions as well as u...
Background: High level of perceived stress in nurses is due to a genetic predisposition and environmental stressors. The aim of NURSE (Nursing Unacquainted Related Stress Etiologies) study was to investigate the association of C677T MTHFR gene polymorphism and stress perception among nurses. Methods: In this comprehensive study, 216 female nurses were recruited. Perceived stress w...
drought stress as the most important abiotic stress plays a significant role in reduction of crops yield. this study was conducted at six agricultural experimental stations (karadj, ardebil, arak, mashhad, jolgerokh and miandoab) during 2006-08 cropping seasons. experiments were carried out under normal irrigation and post-anthesis drought stress conditions using 18 wheat genotypes. experimenta...
