this study aimed to investigate the effects of listening strategy training on iranian efl learners listening comprehension and use of such strategies. this work, employing an experimental methodology, was conducted among 60 adult efl learners from a language institute in isfahan, iran, as participants. the participants, who were selected based on the results of a placement test, were assigned t...
bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...
this study investigates the relationship between field-related cognitive styles and global reading comprehension of hypertext. technically, field dependency is prevailing dominance of field on perception of parts, while global comprehension is skim-like reading to grasp the general content. in this research project, 60 senior and junior students of arak university majoring in english literature...
Estimating groundwater quality parameters through conventional methods is time-consuming laboratory measurements for megacities. There a need to develop models that can help decision-makers make policies sustainable reserves. The current study compared the efficiency of multivariate linear regressions (MLR) and artificial neural network (ANN) in prediction total dissolved solids (TDS) three sub...
Water is essential part of ecosystem, so its quality must be ascertained for use especially in Ekole creek Nigeria where dredging activities heavy, hence this study examined the effect on downstream water creek. samples were collected from four points which are; Upstream, Dredge I, II, and Downstream points. The parameters determined showed that Turbidity Total Suspended Solids (TSS) higher at ...
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
In this work, the assessment of surface and ground water quality Palladam Taluk, Tiruppur, district, Tamil Nadu, India were carried out using Geographical Information System (GIS) Modified National Sanitation Foundation -Water Quality Index (MNSF-WQI). Four samples from twenty seven sources taken Tiruppur District. current study, analysed for temperature, pH, dissolved oxygen (DO), electrical c...
The physico-chemical analysis of groundwater quality plays a significant role to manage the water resources for drinking as well irrigation in sub-humid and semi-arid agro-climatic areas. In this study, hydrogeochemical analyses spatial mapping Jakham River Basin located southern part Rajasthan were investigated.The samples collected from 76 wells marked on grid map 5×5 km2 area.A distribution ...
in this study, the relationship between teachers’ creative and critical thinking skills and their reflectivity in teaching was investigated. to this end, three questions were raised. these questions were intended to determine whether there was a significant relationship between teachers’ creative thinking skills and their reflectivity in teaching; whether there was a significant relationship be...
PURPOSE To automatically segment multiple sclerosis (MS) lesions into three subtypes (i.e., enhancing lesions, T1 "black holes", T2 hyperintense lesions). MATERIALS AND METHODS Proton density-, T2- and contrast-enhanced T1-weighted brain images of 12 MR scans were pre-processed through intracranial cavity (IC) extraction, inhomogeneity correction and intensity normalization. Intensity-based s...
