conclusions in light of our findings, we concluded that ra function is severely diminished in adult patients with tof. it would play an important role in pathophysiological process of the right sided heart failure in these patients. results the myocardial velocities and deformational indices of ra free wall were significantly compromised in tof patients compared with normal subjects. there was ...

in this study, the effect of wall orientation on the optimum insulation position in the wall from different perspectives is studied numerically. using crank- nicolson one dimensional transient heat conduction equation is solved for the wall with convection boundary conditions. outdoor temperature is considered as a periodic function of time. since natural night ventilation is used in the buildi...

Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of  rigid and padded wall tanks in terms of the wave elevat...

place is a part of geographical space and a base for establishment of social relations. each place is unique according to its specific properties, functions and history. meanwhile, some places find symbol identity due to their especial historical events and properties and this identity would be maintained in the minds and moved to the other generations. for example azadi tower in tehran and sav...

quantification of arterial elasticity and its dependency to age is considered in this paper. we use radiofrequency (rf) signals fromcarotid artery ultasonography to evaluate this dependency. blood pressure, blood flow, and tethering to surrounding tissue are the maincauses of the motion of the carotid wall. tracking carotid artery wall motion from a series of ultrasound b‑mode images is challen...
