abstract the primary purpose of this study was to explore the actual practices and cognitions of two groups of iranian eap teachers, i.e. language teachers and content teachers, with respect to teaching reading-comprehension and vocabulary. to this end, tehran university of medical sciences which authorizes both groups of teachers to teach eap courses was selected as the context of the study s...
in order to evaluate the effects of different plant densities and nitrogen levels on growth, yield and qualitative characteristics of marigold, a field experiment was conducted as split plot based on randomized complete block design with four replications at the agricultural research station, azad university of torbat-e-jam, during growing season of 2008-2009. main and sub plots were four nitro...
in order to evaluate the effect of organic fertilizers (compost) and nitrogen on growth and yield of moldavian balm, a split plot experiment in a randomized complete block design with four replications in 1393 at the research station of kerman agricultural and natural resources research and education center was performed. the main plots and subplots of the experiment, respectively, were include...
the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
the present study was an attempt to compare the effect of peer metalinguistic corrective feedback on elementary and intermediate efl learners speaking ability to see which level benefits more from this type of feedback. to this end, 117 female efl learners at grade 3, al-zahra high school in kermanshah, iran were non-randomly chosen. the homogeneity of the participants was attained through a pi...
Adding compost and vermicompost organic fertilizers to soil can improve soil physical conditions, nutrient elements and microorganisms. In the present study, the effect of the cow manure, vermicompost, and urea chemical fertilizer, alone or in combination, on the yield and qualitative characteristics of basil (Ocimuom basilicum L.) was investigated. The experiment was conducted as a split plot ...
Plackett-Burman design was used for selection of important media components such as carbon and nitrogen sources and minerals which affect poly(hydroxybutyrate) production and cell growth of Methylobacterium extorquens DSMZ 1340. Among the studied variables, nitrogen and phosphorus sources, MgSO4 and most of the trace elements were found to be significant variables for PHB product...
Nitrate fertilizers are common source of nitrogen (N) in nutrient solutions. Substitution of urea with nitrate could reduce this dependence. Also, nickel (Ni) is essential for activation of urease in plants fed with urea. For this aim, a factorial experiment was conducted in a completely randomized design with four replicates. Urea in five levels (0, 25, 50, 75 and 100 mg/L) and Ni in two level...
a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
