اگرکیفیت معلم کلاس برای بهبودیادگیری دانش آموزحیاتی است،پس کیفیت اساتیددانشجو-معلمان، یابه عبارتی معلمین معلمان نیزبرای پیشرفت آموزش بسیارمهم واساسی است.ناگفته پیداست که یک سیستم مناسب آموزش معلمان ،معلمین با کیفیتی را تربیت خواهدکرد.که این کار منجربه داشتن مدارس خوب، ودرنتیجه نیروی کارماهرتروشهروندبهتربرای جامعه خواهدشد. اساتیددانشجو-معلمان نقشی بسیارمهم را در سیستم اموزش معلمان درسراسرجهان ای...
Background: Vitiligo is a common pigmentary disorder affecting mental health, and alexithymia is a trait associated with multiple cutaneous disorders. This study was conducted to compare vitiligo patients and controls as concerns alexithymia. Methods: Fifty-two patients with vitiligo and 61 non-vitiligo individuals were recruited. They completed Toronto alexithymia score-20 questionnaire. Indep...
Chronic lymphocytic leukemia (CLL) clones contain subpopulations differing in time since the last cell division (“age”): recently born, proliferative (PF; CXCR4DimCD5Bright), intermediate (IF; CXCR4IntCD5Int), and resting (RF; CXCR4BrightCD5Dim) fractions. Herein, we used deuterium (2H) incorporation into newly synthesized DNA patients to refine kinetics of CLL by characterizing two additional ...
We introduce deep-field metacalibration, a new technique that reduces the pixel noise in metacalibration estimators of weak lensing shear signals by using deeper imaging survey for calibration. In standard when estimating object's response, extra is added to correct effect shearing image, increasing uncertainty on estimates ~ 20%. Our leverages separate, calculate calibrations with less degrada...
Tyrophagus putrescentiae (Schrank, 1781) is an emerging source of allergens in stored products and homes. Feces proteases are the major allergens of astigmatid mites (Acari: Acaridida). In addition, the mites are carriers of microorganisms and microbial adjuvant compounds that stimulate innate signaling pathways. We sought to analyze the mite feces proteome, proteolytic activities, and mite-bac...
Ultrasonic testing is an important flaw detection technology in nondestructive testing field. With its unique electronic scanning, dynamic deflection focusing (DDF), sectorial scanning characters and ultrasonic phased array (UPA) technology can be used for defecting detection of objects with curved face or complex structure. Thus, UPA technology has become a focus of ultrasonic testing research...
We hope this work allows one to calculate large prime numbers directly, not by trial-and-error, but following a physical law. report—contrary conventional assumptions—that differentiation of discontinuous functions (DDF) exists in the set Q, which becomes central algorithms for quantum computation. DDF have been thought exist classical sense, using distributions. However, distributions still is...
Abstract Pétrola Lake in southeast Spain is one of the most representative examples hypersaline wetlands southern Europe. The rich ecosystem and environmental importance this lake are closely associated with hydrogeological behaviour system. wetland fed by underlying aquifer relatively fresh groundwater—1 g L −1 total dissolved solids (TDS)—with a centripetal direction towards wetland. In addit...
The feasibility of simulating daily snowmelt runoff in an arid mountain watershed with limited hydro-meteorological measurements was explored with an enhanced temperature-index snowmelt runoff model (SRM) in which the degree-day factor (DDF) is varied on the basis of shortwave solar radiation and snow albedo. The model satisfactorily simulated snowmelt runoff with a model efficiency of 0Ð64 for...
Abstract: This paper proposes a centralized data envelopment analysis (DEA) model for industrial optimization based on several different production technologies among several regions. We developed this model based on improved Kuosmanen environmental DEA technology, which avoids positive shadow price on undesirable outputs. We also designed a dual model for our centralized DEA model, and used it...
