Noninvasive pulsed Doppler echocardiography combined with two-dimensional echocardiography by the right parasternal approach was performed to detect the shunt flow through the defect in 31 patients with suspected secundum atrial septal defect (ASD). A defect of the interatrial septum was seen on the two-dimensional echocardiograms of 30 of 31 patients. In all the 30 patients, Doppler signals of...

An experimental study is conducted on flow past a circular cylinder fitted with some tripping wires on its surface. The work investigates the dependency of the critical wire locations on the wire size and Reynolds numbers, and examines the wake and vortex shedding characteristics in an effort to advance the understanding of the critical wire effects beyond the existing literature. The primary a...

This study proposes a modeling methodology for the description of tribo-dynamic behavior generic point contacts, considering surface defect/failure type excitation. A twin-disk contact set-up is developed to experimentally determine acceleration induced by lab-controlled groove feature present on one mating surfaces. The periodic passage this artificial defect through lubricated zone leads forc...

BACKGROUND The purpose of this study was to describe the impact of partial lateral glossectomy on midsagittal tongue movement during speech. METHODS Using B-mode ultrasound, the midsagittal tongue movement of 10 patients with lateral partial glossectomy during a standardized reading passage was analyzed before and after surgery. Six normal adults served as control speakers. The main outcome m...

background: lip carcinoma is a common cancer with a good prognosis and when patients refer early in the course of disease the results of treatment are acceptable. surgical procedures for reconstruction of lip defects are the use of remaining lip tissue, tissue from the opposite lip, adjacent cheek tissue, distant flaps and microvascular free flaps. the bitemporal (visor) flap is a regional flap...

The roles of traveling magnetic fields (TMFs) within the transport phenomena during directional solidification nickel-based superalloys were simulated. evolution thermal field, flow field and solid-liquid interface morphology process under both natural forced convection conditions also simulated compared. strength TMFs window that suppresses interfacial front in melt was quantified. association...

Abstract Upon employing the conservation theorem and continuum theory, configurational force on a singularity, or defect, is given by path-independent integral called J integral. According to elasticity around steadily moving dislocation equal Peach–Koehler acting independent of integration path. However, using discrete lattice dynamics method, we theoretically prove that not in practice even u...

congenital left ventricular diverticulum is a rare cardiac malformation. two categories of congenital ventricular diverticulum have been identified with regard to their localization: apical and non-apical. apical diverticula are always associated with midline thoraco-abdominal defects and other heart malformations. non-apical diverticula are always isolated defects. diagnosis is established by ...
