water deficit stress, permanent or temporary, limits the growth and the distribution of natural vegetation and the performance of cultivated plants more than any other environmental factors. mechanism involved is still not clear. in order to investigate the effect of different irrigation intervals and anti-transpirants compoundson yield and yield components of black cumin (nigella sativa), an e...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...

in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
abstractbackground and purpose nowadays, the application of antioxidants and plant growth regulators has discussed for decreasing the negative effect of different stresses. ascorbic acid and sodium nitroprusside have substance caused witch the resistance to biotic and abiotic stresses. to evaluate the effect of ascorbic acid and sodium nitroprusside foliar application on some traits of safflowe...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
in order to study of drought tolerance levels in some wheat lines and cultivars based on uniform regional wheat yield trial (urwyt-m-75) an experiment was carried out using a strip plot design based on complete block design with 3 replications for two years (1998-2000) in torogh agricultural research station (mashhad, iran). the main plots (horizontal factor) were 3 levels of irrigation: 10, 20...
Extended Abstract Introduction and Objective: Various environmental stresses, especially water deficit stress have several and major effects on maize growth and production. Drought is one of the abiotic stresses that due to the great variety of rainfall conditions, it is known from Iran as the most important factor limiting the growth and production of crops. Therefore, the effect of water def...
