INTRODUCTION Laparoscopic duodenal atresia repair is an advanced procedure performed in select pediatric surgical centers. Recently, sub-6mm endosurgical staplers have been introduced, facilitating and accelerating the creation of intracorporeal intestinal anastomoses. PRESENTATION OF CASE We performed a laparoscopic duodenojejunostomy in a one-day-old child with duodenal atresia due to annul...

The nonlinear steady state large amplitude forced vibration response of a laminated composite annular sector plate is presented. governing equation motion the has been obtained using kinematics first-order shear deformation theory (FSDT) and employing Hamilton’s principle. equations have solved in time domain modified shooting method arc-length/pseudo-arc length continuation technique. influenc...

In this paper, numerical investigation of upward two phase flow of air-water has been studied. Different conditions of flow regimes including annular, wispy annular, slug, churn and bubbly are simulated based on Hewitt and Roberts map, and a good agreement between the experimental data of the map and the numerical simulation has been observed. Accordingly, a proper CFD model in CFD software of ...

Using a finite-difference time-domain method, it has been shown that focal spots generated when tightly focusing linearly polarized Gaussian beam by Fresnel zone plate (FZP) and with an embedded optical vortex spiral (SZP) have different patterns of the intensity energy flux. The most significant differences are observed value topological charge (TC) is equal to three. flux annular distribution...

Purpose: To present the results of open reduction and angulating-distraction ulnar osteotomy in children with chronic radial head dislocation. Material and Methods: This is a retrospective review of 4 children (3 girls, one boy) with chronic radial head dislocation treated in our hospital between 2009 and 2012. The average age at the time of surgery was 6.6 (4.2 – 9.1 years).The interval betwee...
