the role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
15 صفحه اولSurface Water–groundwater Interaction in the Fractured Sandstone Aquifer Impacted by Mining-induced Subsidence: 2. Hydrogeochemistry
Water quality along the Waratah Rivulet in the Woronora Lake Catchment, New South Wales (NSW), Australia, has been monitored during the last three years by the Sydney Catchment Authority. Water quality data shows changes in chemical composition due to cracking of streambeds and rockbars, and diversion of surface water into subsurface routes in the Hawkesbury Sandstone aquifer. Water quality ups...
متن کاملRadar Interferometric Analysis of Mining Induced Surface Subsidence Using Permanent Scatterer
We apply the permanent scatterer (PS) technique to interferometric ERS SAR observations to analyse the surface subsidence induced by hard coal mining activities at the ”Prosper-Haniel” mine (Ruhr region, Germany). Underground mining causes extensive subsidence of serveral meters and typically high subsidence rates at the earth‘s surface. We show that this approach is applicable for the measurem...
متن کاملNumerical Analysis of the Resolution of Surface Electrocardiographic Lead Systems
Non-invasive electrocardiographic (ECG) techniques for assessing the electrical activity of selected regions within the cardiac muscle can benefit from suitable positioning of surface electrodes. This positioning is usually guided heuristically and complemented by clinical and experimental studies, but there is a lack of general methods to characterize quantitatively the ability of a given elec...
متن کاملTechnical Notes on the Near Surface Experiments of Submerged Submarine
In this study, the experimental analysis on the bare hull resistance coefficient of submarine at snorkel depth is represented. The experiments are conducted in marine laboratory of Admiral Makarov University. The results are presented for surface condition and snorkel condition. Snorkel depth is regarded equal to one diameter of submarine hull beneath the water surface as usual in submarines. P...
