هدف: امروزه کارگروهی در مؤسسات آموزش عالی به‌عنوان یکی از بهترین راهبردها برای تعامل و مشارکت دانشجویان فرایند یادگیری هم‌چنین کمک به رشد مهارت‌های ارتباطی آن‌ها محسوب می‌شود. درحالی‌ که شناسایی مزایای می‌تواند درک مثبتی را بین اساتید ایجاد کند، عواملی باعث عدم شکل‌گیری تمایل اندک انجام نظام دانشگاهی می‌شود، نیز مزایا تأثیرات مثبت آن بکاهد؛ بنابراین، هدف این پژوهش چالش‌های مرتبط با بود.مواد روش...

The synthesis of a new linear bis-tetraamine ligand L1, based on two 1,4,8,11-tetraazaundecane units grafted at the 2 and 6 positions of a pyridinyl linker substituted by an anthracenyl fluorophore in the para position, is described and anion complexation studies of L1 with anionic substrates are reported. The protonation pattern and the study of the binding properties of L1 in an aqueous mediu...

P olymicrogyria (PMG) is a cortical development defect that results in an irregular brain surface, with multiple, small, partly fused gyri separated by shallow sulci. The perisylvian form is the most common pattern of PMG seen on magnetic resonance imaging scans of the brain. Bilateral perisylvian PMG (BPP) often is accompanied by mild mental retardation, epilepsy, and pseudobulbar palsy, and t...

The paper presents a combination of the time-parallel “parallel full approximation scheme in space and time” (PFASST) with a parallel multigrid method (PMG) in space, resulting in a mesh-based solver for the three-dimensional heat equation with a uniquely high degree of efficient concurrency. Parallel scaling tests are reported on the Cray XE6 machine “Monte Rosa” on up to 16,384 cores and on t...

PURPOSE While there are several reports of prostate multisector dosimetry data obtained from CT or MRI scans performed at intervals ranging from 14-70 days after prostate brachytherapy (PB), there are no reports on multisector dosimetry performed in the immediate post-implant period. This study was undertaken to determine the results of prostate multisector dosimetry performed in the immediate ...
