in order to investigate factors affecting on seed germinating of london rocket (sisymbrium irio), lab experiments were set up in 2011 at the payamenoor university, mashhad, khorasan razavi province. effect of different concentrations of gibberellic acid (ga3) and cytokinin, wet and dry prechilling duration, hydrogen peroxide duration, ethanol, salt and osmotic stress and burial depth on seed ge...
the wet and dry spells can be defined as a number of consecutive months with rain amount greater or less than the truncation level, respectively.analysis of the wet and dry spell properties of monthly rainfall series at 40 meteorology stations in the golestan province is carried out for an extended period of 34 years (1974–2007). the results proved that the patterns of wet and dry spell duratio...
BACKGROUND Wet swallows cause a greater esophageal contraction amplitude and duration than dry swallows. In Chagas' disease there is a reduction in amplitude of esophageal contraction but we do not know if the difference between wet and dry swallows is seen in the disease. AIM To compare the esophageal contractions after wet and dry swallows in patients with Chagas' disease. METHODS We meas...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
seed dormancy is one of the major problems in the study of the effects of different factors on the weed seed germination characteristics because healthy seeds without dormancy, having high vigor and germinability are needed in these studies. this experiment was carried out to find simple, applicable, cheap, quick and efficient methods to breaking seed dormancy in velvetleaf which is one of the ...
Spatio-temporal variability of wet and dry spells can be controlled by climate variability within a watershed and will affect availability of water resources and management plans. The application of the wet-dry spell analysis is presented for seven synoptic stations in the western part of Iran (Kurdistan Province). Numbers of consecutive months with standardized amount greater or less than the ...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
Two experiments were conducted to investigate the differences in susceptibility to foot pad dermatitis (FPD) of two medium-heavy lines of turkeys, and whether FPD is painful, by detailed analysis of behaviour in birds with and without analgesic treatment (betamethasone). Turkeys housed on dry litter in the first experiment generally had more frequent bouts of different behaviours that were of s...
The circadian locomotor rhythm of the terrestrial slug, Limax maximus, was measured with activity wheels during exposure to both humid and drying conditions. Slugs kept in wet wheels (100% RH) remained fully hydrated while those in dry wheels (less than 30% RH) experienced progressive dehydration. Transfer of slugs from a wet wheel to a dry wheel resulted in an increase in the intensity and dur...
