the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...
the purpose of this study was to investigate iranian efl learners’ beliefs about the role of rote learning (rl) in vocabulary learning strategies; besides, the study examined if english proficiency would influence learners’ vocabulary learning strategy use. this study addresses the need for a clear understanding of the role of rl in efl vocabulary learning by looking at iranian efl learners’ ow...
Mobile wallets promise to allow people to easily manage their accounts and to carry less cards. However, the slow adoption of contactless point of sales (POS) terminals by merchants limits the potential of Near-Field Communication (NFC) based payment devices. In this paper, we discuss Wild Card, a secure and backward compatible way to make mobile payment through conventional magnetic stripe bas...
PURPOSE Measures of quality of life called utility values (UVs) are needed to deliver the most cost-effective health care for glaucoma patients. UVs are rarely measured in clinical research and practice whereas clinical outcomes such as visual field are routinely collected. The aim of this study was to develop an algorithm that calculates UVs directly from combinations of routine measures of bi...
Introduction: In this study, dose distribution of the chest wall in post-mastectomy breast cancer patients was evaluated and compared in the tangential wedged beam (TWB) and field-in-field (FIF) plans. Materials and Methods: Thirty-six patients with left-sided breast cancer were enrolled in this study. The FIF and TWB plans were generated for each patient to compare dosimetric parameters of th...
The main goal of preset research is investigate the effects of vertical component of Near-Fault and Far-Field earthquake records on the probability of overtopping induced damage of earth dam due to the reduction of freeboard due to the settlement of dam crest. In this respect 12 different earthquake record are selected. Nonlinear dynamic analysis of earth dam is implemented with FLAC 3D using F...
The objective of this study is to investigate empirically the adoption of credit card contactless payments with smartphones. Contactless Near Field Communication (NFC) mobile payments, that are sought to develop exponentially worldwide in the near future due to their unquestionable advantages, may also face some user doubts. To investigate consumer possible positive and negative perceptions abo...
During September 2000 I spent 5 days touring the Dmitrov Raion in Russia as part of a fact-finding delegation of health care professionals from Minnesota. We were there at the invitation of the Dmitrov Department of Health to assess medical practices and form partnerships to improve care in the region by taking steps to enhance medical and social programs. Our group included five physicians (fa...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
