The time constant of logarithmic creep and relaxation

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...

The Logarithmic Constant : log 2

An introduction to the history of the constant log 2 and to its computation. It includes many formulas and some methods to estimate it, as well as the logarithm of any number, with few digits or to the greatest accuracy. ...by shortening the labors, doubled the life of the astronomer. Pierre Simon de Laplace (1749-1827) about logarithms. You have no idea, how much poetry there is in the calcula...

Comparison of Isovolumic Relaxation Time and Transmitral Flow Velocities With Time Constant of Isovolumic Relaxation

msec (p=0.04) with a concomitant decrease in IVRT from 74±18 to 38±8 msec (p=0.03). During decreased inotropy (by propranolol infusion) at constant preload, slowing of relaxation was indicated by an increase in T from 40±8 to 51±+13 msec (p=0.02) with a concomitant increase in IVRT from 71±+15 to 83+±21 msec (p<0.05). A significant correlation between changes in and changes in IVRT was found (r...

Creep and Stress Relaxation Behavior of Polypropylene, Metallocene-Prepared Polyethylene and their Blends

the effect of task cognitive complexity and time limit on the performance of the learners with different proficiency levels in second language writing skill

this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...
