the debate whether esp teachers need to have knowledge of the specialized field they are teaching has been an issue in the literature over the last two decades. the aim of conducting this study was to explore iranian learners’ and instructors’ beliefs and attitudes concerning the role of specialized knowledge in teaching esp classes. a seventeen item questionnaire was administered to 400 esp le...
objective(s): apolipoprotein e genotype (apoe) polymorphism affects lipid levels and coronary artery disease (cad) risk. the aim of this study was to study the association of the apolipoprotein e genotypes with coronary artery disease in the iranian population. materials and methods: the apolipoprotein e genotype in dna samples extracted from 66 cad+ patients and 61 control subjects by restri...
this study attempts to investigate the effect of peers’ revision in comparison to that of the teacher, and whether peers’ comments and teachers’ comments facilitate students’ revision? if yes, which one is more effective? also attempts have been made to see which aspects of language are more highlighted by peers versus teachers when commenting. besides, it is investigating the student’s attitud...
extremely low frequency (elf) electromagnetic field (elf-emfs) are widely employed in electrical appliances and different equipment such as television sets, elf-emfs can affect biological systems by increasing production ros. the altered balance between ros generation and elimination plays a critical role in a variety of pathologic conditions. ros levels have been observed in several hematopo...
Decentralized control strategies are popular candidates in microgrids control because of their reliability and performance. Conventionally, droop control (as a main decentralized strategy) is been utilized in order to prevent permanent droop of voltage and frequency after change in loads and also to share generated power between distributed generation units. In this paper, a new droop control s...
Cultural transmission of reproductive success states that successful men have more children and pass this raised fecundity to their offspring. Balaresque and colleagues found high frequency haplotypes in a Central Asian Y chromosome dataset, which they attribute to cultural transmission of reproductive success by prominent historical men, including Genghis Khan. Using coalescent simulation, we ...
“All models are wrong but some are useful" [1]. We address the problem of identifying which diagnosis models are more useful than others. Models are critical to diagnostics inference, yet little work exists to be able to compare models. We define the role of models in diagnostics inference, propose metrics for models, and apply these metrics to a tank benchmark system. Given the many approaches...
An analysis of the climate parametrization scheme adopted by conventional forest gap models revealed that most models assume a constant climate and are difficult to calibrate consistently. Tree growth showed unrealistically sensitive threshold effects along ecological gradients of temperature and precipitation. A new parametrization was compared with its predecessors in terms of the model's cap...
Title: Oscillometric measure of blood pressure detects association between orthostatic hypotension and depression in population based study of older adults Author's response to reviews: see over Dear Sir/Madam The authors would like to thank the reviewers for their comments and suggestions with regard to the manuscript entitled 'Oscillometric measure of blood pressure detects association betwee...
BACKGROUND Pay for performance (P4P) schemes have become increasingly popular innovations in primary care and have generated questions about their effect on improving quality of care. AIMS To provide a brief outline of the international evidence on the relationship between P4P schemes and quality improvement. METHOD We conducted a literature search using relevant databases and reference lis...
