cauliflower-like nanostructure of cadmium oxide was synthesized by utilizing mechanochemical reaction followed calcination procedure for the first time. the design of experiment (doe) by taguchi method was used to study influence of the chosen factors and to consider optimum conditions of the experiments. the temperature of calcining, the duration of milling, the duration of calcining and react...

one of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. in order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...

The effect of hyperthermia on cognitive function remains equivocal, perhaps because of methodological discrepancy. Using electroencephalographic event-related potentials (ERPs), we tested the hypothesis that a passive heat stress impairs cognitive processing. Thirteen volunteers performed repeated auditory oddball paradigms under two thermal conditions, normothermic time control and heat stress...

the present study was designed to evaluate the drought tolerance of new sugar beet monogerm hybrids using polyethylene glycol 6000, under in vitro condition. the experiment was carried out as a factorial experiment based on completely randomized design with four replications in sugar beet seed institute, karaj in 2013. 23 new sugar beet monogerm hybrids with two tolerant and normal controls wer...

In contact with an environment, a solid may gain or lose mass due to, for example, deposition or etching. As the reaction proceeds, the surface of the solid moves, either extending or receding. If the solid is under stress, the elastic energy adds to the driving force of the reaction, and may cause the surface to roughen. This phenomenon has recently led to a novel experimental technique to det...

in order to investigate of the effects of water stress on seed yield and gas exchange and to evaluate the relationship between source and sink in sunflower azargol variety, a split-plot factorial field experiment was conducted in 2008. in this experiment, water stress (no irrigation from 30 days after sowing till ripening) and irrigation (irrigation at -3 bar soil water potential) were consider...
