High-resolution Spectra of Very Low-Mass Stars
We present the results of high-resolution (1-0.4 Å) optical spectroscopy of a sample of very low-mass stars. These data are used to examine the kinematics of the stars at the bottom of the hydrogen-burning main sequence. No evidence is found for a significant difference between the kinematics of the stars in our sample with I–K > 3.5 (MBol ∼ 12.8) and those of more massive M-dwarfs (MBol ≈ 7 − ...
متن کاملthe impact of computer-assisted language learning on achievement motivation of high school students
چکیده انگیزه دلیل اصلی رفتارهای ما است. به نظر می رسد انگیزه جزء جدایی ناپذیر فرایند یادگیری باشد. ارزش ذاتی موفقیت تمایل به پیشرفت را در یادگیرنده ایجاد میکند. به عبارت ساده این تمایل انگیزه پیشرفت نامیده میشود. انگیزه پیشرفت را میتوان در احساس یادگیرنده هنگام چالش با درس های مدرسه، لذت انجام فعالیت درسی، یا حس کشف پاسخ مشاهده کرد.حتی ممکن است انگیزه پیشرفت را در تلاش یادگیرنده برای جلب تایید...
the effect of explicit instruction of metacognitive strategies on reading comprehension among iranian high school students
the present study seeks to determine the effect of explicit instruction of metacognitive strategies on iranian high school students’ reading comprehension ability. it also attempts to investigate the relationship between the learners reading comprehension and metacognitive strategies. furthermore, the study investigates whether iranian efl female high school students are high, medium, or low me...
the effects of listening comprehension on efl high school learners reading comprehension
the following question poped up: is there any relationship between iranian high school efl learners reading comprehension and listening comprehension? then the following null hypothesis (ho) was developed to the test the above, mentioned question. "there is no relationship between high school efl learners reading comprehension and listening comprehension. for nearly 16 weeks, the experimental g...
15 صفحه اولComputer Simulations of High Resolution NMR Spectra
The evolution of a spin system during the application of an RF pulse is a central aspect of high resolution NMR spectroscopy. An appropriately applied field can lead to saturation or decoupling effects. When a field is used to maintain a spinlocked condition, both scalar and dipolar interactions come into play, leading to coherence transfers and nuclear Overhauser effects that form the basis of...
