abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
the effect of full irrigation (fi), partial root-zone drying at two levels (receiving 75 percent of et (prd75), 55 percent of et (prd55)) and deficit irrigation treatments at the same levels (75 percent (di75) and 55 percent (di55)) under drip irrigation on nitrogen uptake and leaching in a maize field in sari agricultural sciences and natural resources university were carried out during years ...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
Sesame is one of the oldest crops in the world that is commonly cultivated in arid and semi-arid due to high oil seeds (42-52%). In order to determine the effects of water deficit (55, 75 and 85 percent evacuation of soil water) on genotype sesame (Varamin, Naztakshakhe, Oltan and Yekta), a field experiment was conducted using a split-plot in randomized complete design with three replication at...
Among the environmental barriers to plant growth and yield, drought, an icon of arid and semi-arid regions is the most important factor in reducing production. Teucrium polium L. is one of the most important medicinal plants of the family Lamiaceae that exists in these areas. In order to study the effect of drought stress on some physiological and morphological traits of Teucrium polium L., an ...
Hyperpolarized (3)He MRI previously revealed spatially persistent ventilation defects in healthy, older compared with healthy, younger never-smokers. To understand better the physiological consequences and potential relevance of (3)He MRI ventilation defects, we evaluated (3)He-MRI ventilation-defect percent (VDP) and the effect of deep inspiration (DI) and salbutamol on VDP in older never-smok...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
the effects of pulsed electric field (pef) on the cell disintegration of sugar beet were studied. field strength (0.5kv/cm to 6kv/cm), pulse number (1 to 100 pulses) and capacity of capacitors (0.5 f to 32 f) were evaluated on degree of cell disintegration and consumed energy in pef treatment. the field conditions of 1 and 2 kv/cm, 8 f with 20 and 10 pulses respectively disintegrated the cel...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
