the effects of previewing and providing background knowledge on iranian university efl learners’ comprehension of literary and academic texts
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
15 صفحه اولMean diurnal variations of noctilucent clouds during 7 years of lidar observations at ALOMAR
From 1997 to 2003, noctilucent clouds (NLC) were observed by lidar above the ALOMAR observatory in Northern Norway (69 N) during a total of 1880 measurement hours. This data set contains NLC signatures for 640 h, covering all local times, even during the highest solar background conditions. After data limitation imposing a threshold value of 4×10−10 m−1 sr−1 for the volume backscatter coefficie...
متن کاملComparison of the atmosphere above the South Pole , Dome C and Dome A : first attempt
The atmospheric properties above three sites (Dome C, Dome A and the South Pole) on the Internal Antarctic Plateau are investigated for astronomical applications using the monthly median of the analyses from ECMWF (the European Centre for Medium-Range Weather Forecasts). Radiosoundings extended on a yearly time scale at the South Pole and Dome C are used to quantify the reliability of the ECMWF...

We demonstrate that the process e + e − → tth at the NLC provides a powerful tool for extracting the tt (Yukawa) couplings of the h. In combination with the e + e − → Zh process , an accurate determination of the ZZ coupling of the h is also possible. The resulting ability to distinguish different models of the Higgs sector is illustrated by detailed studies for two-Higgs-doublet models. In ext...
