abstract: the present study is an attempt to find out cultural exophoric references in iranian high-school elt textbooks and touch stone series to compare the frequency of occurrence of such references in these books. the purpose is to find out which of the series of the books under investigation impose a greater referential burden on efl learners as far as their reading comprehension of the ...
Background & objectives: Cutaneous leishmaniasis (CL) is an endemic disease in district of Bam. It has created considerable concerns by people and health authorities. The objective of this study was to assess the effect of the earthquake and costs of prevention on CL prevalence after earthquake Methods: This research is based on a natural intervention, in which the information related to the...
This study develops an end-to-end deep learning framework to learn and analyze ground motions (GMs) through their latent features, achieve reliable GM classification, selection, generation of simulated motions. The is composed analysis workflow that transforms reconstructs GMs short-time Fourier transform (STFT), encodes decodes features convolutional variational autoencoder (CVAE), classifies ...
Pulse period of earthquake records has been known as a key parameter in seismology and earthquake engineering. This paper presents a detailed characterization of this parameter for a special class of earthquake records called pulse-like ground motions. This type of motions often resulting from directivity effects is characterized by a strong pulse in the velocity time history of motion, in norm...
the caspian sea contains great resources of oil and gas. the caspian sea is a 700- mile- long body of water in central asia, land located between azerbaijan, iran, kazakhstan, russia and turkmenistan. iran was challenges and opportunities in the caspian region. key question in this thesis includes three section that first question, opportunities of iran in the caspian region, second question ch...
the present study attempts to discover ideological differences between alcott’s novel (1868) named “little women” and its two persian translations. the first has been translated by morvarid and the second has been translated by obeidi. to this end, farahzad’s cda approach (2012) was used to analyze the ideology reflected in both translations by the two different translators. according to farahz...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...
the main purpose of the present study was to investigate the relationship between listening proficiency and metacognitive listening strategies awareness among low, mid, and highly self-regulated students. three hundred and seventy one efl students participated in this study (all grade 3 and 4 high-school students who were studying in khansar in academic year 1391-92). to gather the data, three ...
We performed simulations of ground motions in Mexico City expected for large earthquakes in the Guerrero seismic gap in Mexico. The simulation method uses as empirical Green's functions the accelerograms recorded in Mexico City during four small to moderate earthquakes (8 Feb. 1988, M s = 5.8; 25 April 1989, M w = 6.9; 11 May 1990, M w = 5.5; and 31 May 1990, Mw = 6.0) in the Guerrero gap. Beca...
