ABSTRACT- To investigate the effects of bio-chemical and organic fertilizers on yield and seeds NPK contents of pumpkin (Cucurbita pepo var. styriaca), an experiment was conducted at the Research Farm of Kurdistan University in 2009 growing season. Treatments were included 1) control, 2) seeds inoculated with free-living N fixing bacteria (NFB), 3) seeds inoculated with phosphate-solubilizing b...
Background and Purpose: Candida species constitute an important group of opportunistic fungi, which cause various clinical diseases. Considering the resistance of some Candida species to conventional antifungal agents, treatment of such cases may be challenging and complicated. The purpose of this study was to evaluate and compare the antifungal activities of Euphorbia macroclada latex and fluc...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
In order to investigate the effect of form of nitrogen (N) [ammonium (NH4) and nitrate (NO3)] and calcium (Ca) levels of nutrition solution on quantitative and qualitative yield of cut rose flower (Rosa hybrida L.), cv. Vendentta, in soilless culture condition, an experiment was conducted in greenhouse of the National Ornamental Plants Research Station of Mahallat. The experiment was factorial,...
Subsequent to phytochemical investigation on scutellaria lateriflora (Labiatae) from Mazandaran provincein Iran, the wax ester fraction of the leaves has been investigated. Using TLC, CC GLC and GLC-MS, the alkyl esters of the epicuticular wax was analysed. Total concentration of the esters was 35% and it was shown to be composed of a homologous series having various chain lengths in the ra...
improving the soil quality with organic matter content and presence of elements such as n, p and k are some of sewage sludge benefits. adjusting carbonaceous materials such as plant wastes to dewatered sludge compost increases its moisture and improves c/n ratio. so dewatered sludge has low c/n ratio and should be mixed with bulking agents. this study was performed in a three months period of t...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
The time dependent progress of a chemical reaction over a flat horizontal plate is here considered. The problem is solved through the group similarity transformation method which reduces the number of independent by one and leads to a set of nonlinear ordinary differential equation. The problem shows a singularity at the chemical reaction order n=1 and is analytically solved through the perturb...
