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...

Three strains of facultatively anaerobic thermotolerant and moderately halophilic bacteria were isolated from two Jordanian hot spring locations. The novel Bacillus strains were short rods, Gram-positive, motile and spore formers. The strains were capable of anaerobic (but not aerobic) growth at 63C, moderately halophilic, able to grow at NaCl concentration range of 12 15 % and at temperatures ...

Face recognition is important in human identification. The biological recognition technique acts as a good method and broad applications in security areas. This work presents a method to improve the face recognition accuracy using a combination of Principal Component Analysis (PCA), and Wavelet Transform. Wavelet Transform is used to decompose the input image with different levels and rearrange...

صخلملا Infertility affects 15% of couples seeking children worldwide and male factor is evident in about 30-50% of the cases. To assess the effect of sperm chromatin integrity on the outcomes of intracytoplasmic injection, sperm DNA compactness was evaluated by acridine orange staining in 40 fertile and 44 infertile men attending one infertility clinic.

صخلملا The search for novel anticancer drugs continues. This work includes a preliminary study of the effect of two crude extracts of Greek or Mediterranean sage (Salvia triloba L. f.) on three malignant human cell lines and one malignant murine cell line. A boiling water extract and a methanolic extract were prepared from dried leaves of S. triloba. Yields of extraction were 9.8 and 22.4%, res...
