cold stress is considered as a restricting factor in plant production. recently, many different compounds were applied to minimize the harmful effects of stress. in this study, the effects of foliar application of salicylic acid was studied on some biochemical properties of two different cold resistant canola cultivars. salicylic acid was sprayed at four concentrations (0, 100, 200 and 400 µm) ...

introduction there are significant differences in the spatial distribution of the iran annual precipitation. this is resulted from spatial behavior of precipitation in the one hand and variation in the sources of precipitation on the other. the lack of adequate distribution of meteorological stations and the unavailability of long-term statistics of precipitation makes the analysis of precipita...

an action resulting from an object like human's damaging action can cause liability for those who possess them. the french civil law at its approval time (1804) had not predicted this principle and just in articles 1385, 1386, the liability of damages resulting from two types of objects, i.e. animals and buildings due to imposing great damages by them had been predicted by french law. howe...

global warming and climate change have drawn special attention to soil and its potential for stable carbon sequestration. soils are the largest stores of carbon in terrestrial carbon cycle and contain about three times more carbon than vegetation cover and two times more than that of atmosphere. studying the effects of grazing on soil carbon storage is important because of the major role soil o...

the 17-4ph alloy is a martensitic stainless steel with 3–5 wt% cu, strengthened by the precipitation hardening. due to excellent mechanical properties, corrosion resistance and ease of heat treatment, this alloy has unique applications in nuclear power plants and marine constructions. in this paper, the influence of ageing heat treatment, solution annealing followed by ageing at 480, 550 and 62...

the complexity of the genetic control of drought tolerance makes inevitable using of molecular methods with biometric approaches to its improvement in plants. present study was conducted by 121 advanced lines and varieties of soybean under two moisture levels, normal and drought stress with 21 microsatellite markers linked to drought tolerance in two regions, namely, rasht and gonbad-kavous. gr...

glutamate as one of the most important neurotransmitter in the brain has a significant role in control of foodintake. this study examined the central effect of chicago sky blue 6b (csb6 ) as glutamate vesicular uptake inhibitor, on food and water intake in broilers. after icv injection of csb6 cumulative food and water intake were measured in 15,30,60,120 and 180 minutes. csb6 increased food in...

normal 0 false false false en-us x-none ar-sa background: stroke is one of the most common causes of disabilities and death all over the world. the mortality rate of stroke is predicted to be doubled by 2030 in the middle east countries. nutrition is an effective strategy in prevention and management of stroke. this study assessed the relationship between various protein types and stroke risk. ...

soil reduces the hazardous effects of compounds on the components of ecosystem because of self –purification property and the ability for their fixation. playing such a role in soils under redox conditions is performed by pedogenic fe-mn concentrations. in order to investigate cobalt, copper and lead accumulation in iron and manganese concentrations, at first the concentrations were precisely s...

a completely randomized design (crd) with three replications was conducted at greenhouse of urmia university in 2013 to study the effect of different methyl jasmonate concentrations (0, 0.1 and 0.5 mm) on the activity of enzymes polyphenol oxidase, phenylalanine ammonia lyase, catalase, ascorbate peroxidase, guaiacol peroxidase and total protein content in basil. activity of the enzymes and tot...
