the present study sought to investigate the impact of using mind-mapping technique instruction on female elementary efl learners reading comprehension; it also investigated their attitudes towards using mind-mapping technique as a tool to improve their reading comprehension. this study followed a quasi-experimental design with two intact groups as experimental, and control groups. the participa...
A corrosion inhibitor suitable for industrial production and field application was rapidly synthesized from benzene-1,2-diamine, benzaldehyde, methanol, hydrochloric acid, and FeCl3. The mechanism of corrosion and its inhibition was proposed. We investigated the effect of the main reactants on corrosion rate, and optimal synthetic composition (benzene-1,2-diamine 10 g, b...
BACKGROUND Experimental designs constitute a vital component of all Stated Choice (aka discrete choice experiment) studies. However, there exists limited empirical evaluation of the statistical benefits of Stated Choice (SC) experimental designs that employ non-zero prior estimates in constructing non-orthogonal constrained designs. This paper statistically compares the performance of contrasti...
background: enzymatic hydrolysis of lactose is one of the most important biotechnological processes in the food industry, which is accomplished by enzyme β-galactosidase (β-gal, β-d-galactoside galactohydrolase, ec 3.2.1.23), trivial called lactase. orthogonal arrays design is an appropriate option for the optimization of biotechnological processes for the production of microbial enzymes. metho...
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
the aim of this study is investigating the effect of teaching “metacognitive strategies” on the way which scientific information retrieval workes by the using of google scholar searching machine on the students of ms in the psycology & education faculty of allameh tabatabayi university in 2007-2008 academic year. the statistical community was the students of ms in psychology & education facult...
The Taguchi method was applied as an experimental design to determine optimum conditions for colour removal from azo dyes solutions containing remazol yellow G by electrocoagulation (EC) using iron and steel electrodes as anode and cathode, respectively. An orthogonal array (OA9) experimental design that allows to investigation the simultaneous variations of four parameters (initial remazol ye...
