results based on these findings on agar diffusion with (p = 0.764), mic and mfc tests (p = 0.879), there were no significant differences between the antifungal effect of herbal and chemical mouthwashes. conclusions this study showed that, chemical mouthwashes acted better than herbal mouthwashes and among different chemical mouthwashes, oral b was most effective. objectives the aim of the curre...

To investigate the effect of NaCl concentration on the survival of Aedes aegypti larvae, samples of Aedes aegypti larvae were collected from some discarded container, artificial pool from the urban area of Wahga town and exposed to 10%, 15% and 20% of NaCl concentration. The results of this study suggest that NaCl higher concentration can be used in a more human non-lethal chemical approach and...

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...

it is necessary to care the quantity and quality of the water resources especially in arid and semi-arid regions. shahrekord plain where it has a 551 km2 total area, groundwater is discharging almost 255 mcm annually and uses for drinking and agriculture. the main objective of this study was classification of groundwater quality and comparison with the drinking water standard limits in shahreko...

An isothermal endoreversible chemical engine operating between a finite high-chemicalpotential reservoir and an infinite low-chemicalpotential reservoir in which the mass transfer between the working fluid and the mass reservoirs obeys the linear mass-transfer law [g ∝ ∆μ], is put forward in this paper. Optimal control theory is applied to determine the optimal cycle configuration corresponding...

The equation that approximately traces the trajectory in the concentration phase space of chemical kinetics is derived based on the rate of entropy production. The equation coincides with the true chemical kinetics equation to first order in a variable that characterizes the degree of quasi-equilibrium for each reaction, and the equation approximates the trajectory along at least final part of ...

in order to effects of fertilizer source and intercropping ratios on macronutrients concentration and uptake of fenugreek and black cumin, a factorial experiment was conducted as randomized complete block design with three replications at shahrekord university research farm in 2013. sole cropping of fenugreek (f) and sole cropping of black cumin (b) and three intercropping ratios (f:b 2:1, f:b ...

The metal-assisted chemical etching (MACE) was used to synthesis silicon nanowires. The effect of etchant concentration, etching and chemical plating time and doping density on silicon nanowires length were investigated. It is held that the increasing of HF and H2O2 concentrations lead to etching rate increment and formation of wire-like structure. The results show that, the appropriate ratio o...

ABSTRACT: In this study the non-saponifiable matter of oils extracted from nine varieties of sunflower seed were subjected a series of chemical tests. The non-saponifiable matters were fractionated into a number of chemical classes of compounds namely sterols, 4 methyl sterols, triterpene alcohols, tocopherols and hydrocarbons. The two major and important classes of compounds consisting of ster...

High-throughput screening (HTS) of chemical compounds to identify modulators of molecular targets is a mainstay of pharmaceutical development. Increasingly, HTS is being used to identify chemical probes of gene, pathway, and cell functions, with the ultimate goal of comprehensively delineating relationships between chemical structures and biological activities. Achieving this goal will require ...
