Application of plant growth promoting rhizobacteria and foliar application of Nano-Zinc oxide are proper and cheap method for increasing of Triticale yield. So, in order to study of the effects of nano-zinc oxide and seed inoculation with plant growth promoting rhizobacteria (PGPR) on contribution of dry matter remobilization and stem reserves in grain yield, chlorophyll content, stomata conduc...
This research was conducted to evaluate effects of mycorrhiza fungi and nano zinc oxide on agro physiological traits of wheat under salinity stress based on factorial experiment according complete randomized block design with three replications under greenhouse condition at 2014. Treatments included salinity in three levels [no-salt (S0) or control, salinity 40 (S1) and 80 (S2) mM NaCl], two le...
Statement of Problem: Zinc contained cements are so important among dental material as they have many indications and used in different ways therefore evaluation of their physical properties is so important in dentistry.Purpose: The purpose of this research was to measure some physical properties of zinc-contained cements used in restorative dentistry. These cements included: Zinc oxide-eugenol...
background: antibiotic resistant bacteria can be considered as a main problem in infection management. zinc oxide nanoparticles (zno nps), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. methods: in this study, zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...
Background :Nowadays, nanotechnology has been developing rapidly and may have considerable effects on industry, society and the environment. In this research the toxicity properties of zinc oxide nanoparticles with a size of 20 nm on enzyme and liver tissue of NMRI mice were studied. Materials and Methods: This experimental study was performed in standard conditions on 25 NMRI mice with an aver...
Zinc oxide nanoparticles have been synthesized by chemical reaction method. Polyvinyl alcohol (PVA) composite film filled with nanometric, monodispersed zinc oxide nano particles prepared by PVA solution and nanozinc oxide. Polymer blend with ZnO nanoparticle composite film has prepared by casting technique. The property of nano composites depends greatly on the chemistry of polymer matrices....

abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
In order to study the effects of bio fertilizers and zinc application on yield, variations of quantum yield, stomatal conductance and some physiological traits of triticale under water withholding conditions, a factorial experiment was conducted based on randomized complete block design with three replications. Experimental factors were included water withholding in three levels (normal irrigat...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
