abstract this study examines the relationship between reading anxiety and difficulty of texts as well as the relationship between reading anxiety and students perceived difficulty of the texts. since difficulty is a relative concept, i limited its definition by sticking to the readability formula. we also took students perceived difficulty levels into account. therefore, in the present study, ...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
This paper will present a novel procedure for performing accelerated wear test on Hall thruster discharge channels. The procedure takes advantage of a number of recent advances in optical diagnostics that have enabled increasingly accurate non-intrusive determination of both the length of the erosion zone and the erosion rate of the discharge channels in a Hall thruster. In the proposed procedu...
The nonlinear magneto-optical Kerr-effect (NOLIMOKE) is determined for freestanding Fe monolayers with several in-plane structures from first principles. Based on the theory of nonlinear magneto-optics by Hübner and Benne-mann [Phys. Rev. B, 40, 5973 (1989)] we calculate the nonlinear susceptibil-ities of the monolayers using the ab initio FLAPW-method WIEN95 with the additional implementation ...
Abstract Objective The present simulation study aimed to assess positive predictive value (PPV) and negative (NPV) for our newly introduced Accounting Expected Adjusted Effect test (AEAE test) compare it PPV NPV a traditional zero-order significance test. Results AEAE exhibited greater compared test, especially with strong true adjusted effect, low prior probability, high degree of confounding,...
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...
