today bleach and detergents are being frequently used and some people use their mixture for more cleaning. because of chemical interaction of bleach and detergent, chlorine gas was released and thereby it could be dangerous for human health. this study examined the effects of exposed toxic mixture of bleach and detergent on the mucosa layer and lamina mucosa conjunctiva in the mice. in this stu...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
This experiment was conducted to investigate the effect of ginger and nettle powders and their mixture in comparison with antibiotic growth promoter in a completely randomized design with 5 treatments, 4 replicates and 8 chicks per replicate in commercial broilers. The experimental treatments were:1) control (with no additive); 2) basal diet with 0.04% tetracycline antibiotic growth promoter (5...
The structures (except stereochemistry) of the main components of the rancinamycin complex were determined with IR, UV, and NMR spectra. Rancinamycin I is a mixture of 5 isomeric components, designated Ia, Ib, Ic, Id and Ie. Rancinamycin II is also a mixture of 5 isomeric compounds, designated rancinamycins IIa-IIe. Differences in the acyl group or in stereochemistry probably account for the is...
building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...
In this study, a multi nanosensor was fabricated for the simultaneous detection of carbon dioxide, methane, ethanol, and ammonia gases, and its electrochemical response to various concentrations of these gases were investigated. In order to fabricate this multi nanosensor, in the first phase, the Graphene-Oxide/Polyaniline (GO/PANI) nanocomposite was synthesized. Chemical ...
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
in order to study the impacts of mechanical (using cultivation), chemical (using herbicides) methods and their integration in controlling broadleaf weeds in sugar beet fields, this experiment was carried out as a randomized complete block design with 4 replications in mahidasht-kermanshah in 2006. in this experiment, 9 different treatments consisting a mixture of post-emergence herbicides phen...
Objective(s): Metabolic syndrome is a multiplex risk factor for diabetes and cardiovascular disease. Since some dietary fats such as mono-unsaturated fatty acids (MUFA) modify metabolic syndrome components the aim of the present study was to evaluate the preventive effects of mixture, kernel and hull oils of wild pistachio (WP) (Pistacia atlantica mutica) as good sources of MUFA on different f...
Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining yield and improving flour quality. A field experiment was conducted to examine the responses of three spring wheat varieties in pure variety and in variety mixtures under continuous cropping in Northeast China. Three modern spring wheat varieties, along with a three-variety mixture and a t...
