abstract the purpose of this study was to find out the effect of applying the principles of group-dynamic assessment (g-da) on learning of conditional structures in english by iranian efl learners at the intermediate level, which according to the formal educational system in iran, includes students who are in their second year of studying in high schools of koohdasht city. this study was a qua...
BACKGROUND The objective was to evaluate efficacy and safety of rapid, large-dose intravenous (IV) administration of ferric carboxymaltose compared to oral iron in correcting iron deficiency anemia due to heavy uterine bleeding. STUDY DESIGN AND METHODS In a randomized, controlled trial, 477 women with anemia, iron deficiency, and heavy uterine bleeding were assigned to receive either IV ferr...
BACKGROUND Oral ferrous iron therapy may reinforce intestinal inflammation. One possible mechanism is by catalyzing the production of reactive oxygen species. We studied the effects of low-dose oral ferrous fumarate on intestinal inflammation and plasma redox status in dextran sulfate sodium (DSS)-induced colitis in rats. METHODS Forty male Wistar rats were divided into 5 groups: no intervent...
Despite efforts to improve iron supplements for iron deficiency anemia, there is no consensus on products that balance efficacy, safety and tolerability, and cost. Ferrous products are effective, but they are associated with more gastrointestinal side effects than ferric products. Ferric products tend to have lower absorption. We present results from a 12-week study that randomized 72 people wi...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
the present research was conducted to accomplish two purposes. firstly, it aimed to explore and describe schematic structure or what halliday and hassan (1989, p.64) have called “generic structure potential” (gsp) of american english, iranian persian and iranian english newspaper editorials within systemic functional linguistics. secondly, a quantitative cross-comparison was made to investigate...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
By means of a thermogravimetric analysis coupled with mass spectroscopy, the catalytic effect ferrous sulfate on pyrolysis African Palm husk (APH) was studied. Thermogravimetric data were adjusted to distributed activation energy model (DAEM) four pseudo-components. Ferrous had strong influence decomposition parameters second and fourth pseudo-components DAEM, which are identified as hemicellul...
An integrated bioleaching system (stable pH-silver ion-chloride ion) was firstly proposed to for improving the efficiency of chalcopyrite bioleaching by mixed strains of Acidithiobacillus. The individual effects of stable pH, silver ion, and chloride ion on bioleaching were respectively studied. The highest copper ion concentrations in each system were 45.8, 50.2, and 45.2 mg/l, respectively, w...
In an attempt to rlucidatc the mrrhnnism of the enzymic hydrosylation of aromatic compounds, we have isolated and partislly purified an aromatic hydrosglase from a soil bacterium. This enzyme, which will be referred to as “salicylate hydroxylase,” is soluble and relatively stable, in contrast to most hitherto known aromatic hydrosylascs, and ratalyzes a stoichiometric conversion of salicylate ‘...
