Anode Current-Time Curves and Potential-Time Curves of Aluminum in Sulfuric and Hydrochloric Acids under Controlled Potential Electrolysis

the effects of time planning and task complexity on accuracy of narrative task performance

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...

Modeling Current and Future Potential Distributions of Caspian Pond Turtle (Mauremys caspica) under Climate Change Scenarios

Although turtles are the most threatened taxonomic group within the reptile class, we have a very limited understanding of how turtles respond to climate change. Here, we evaluated the effects of climate changes on the geographical distribution of Caspian pond turtle (Mauremys caspica). We used an ensemble approach by combining six species distribution models including artificial neural network...

Evaluation of Neurogenic Potential of Human Umbilical Cord Mesenchymal Cells a Time- and Concentration- Dependent Manner

Background: Retinoic acid as one of the most important regulators for cell differentiation was examined in this study for differentiation of human umbilical mesenchymal cells (hUCM). Methods: After isolation, hUCM were evaluated for mesenchymal stem cell properties by flow cytometry and alkaline phosphatase assay. Also, doubling time of the cells and their differentiation potential into adipoge...

Rational Functions of a Complex Variable and Related Potential Curves.

This implies that in this case n2r is the kernel of the natural homomorphism of 7r2 into the 2-dimensional integral homology group of X. Comparing this with recent results of Hopf5 yields numerous examples of spaces with k3 $ 0. 5. Generalizations.-1°: The construction of k3 generalizes in an obvious fashion to yield a cohomology class kn+1 e Hn+l(irj, 7r,,), provided that 7ri = 0 for 1 < i < n...
