Due to the technical nature of speed skating, that is affecting physiological mechanisms such as oxygenation and blood flow, this sport provides a unique setting allowing us to uncover novel mechanistic insights of the physiological response to exercise in elite middle-distance and endurance sports. The present study aimed to examine the influence of skating mode (short-track vs. long-track) on...

In this work, variation of parameter method is applied to study two-dimensional flow of nanofluid in a porous channel through slowly deforming walls with suction or injection. The results of the developed approximate analytical solution using the variation of parameter method is verified with the results of numerical solution using fourth-order Runge-Kutta method coupled with shooing techniques...

the main purpose of this investigation is to study the effect of near miscible co2 injection in different porous mediums on both lab and field scales. this effect can be traced by the change of two-phase gas-oil relative permeability curves. in this work, the experiments have been performed on three rock types (i.e. sandstone, dolomite, and artificial fractured sandstone) based on an incrementa...

Introduction:     women's  employment  is one of the fundamental problems in breastfeeding. Studies have shown that after delivery, amount of milk is  equal in the mothers working and non-working. But  after several   months will be reduced markedly. Methods: In this study, with different departments was done coordination , and interviewed with the 351 mothers that had children under two years...

it has been stated that near work can cause myopia progression1-3 and carpet weaving is included in that frame of work.   carpet weaving is a meticulous and very fine handwork which is performed from a very near distance for hours and hours each day and for many years in life-time. a precise visual attention and concentration is needed in this job.   in this current issue of iranian journal of ...
