The purpose of this study was to evaluate two perforated sills in the stilling basin and their impact on characteristics of the hydraulic jump, such as the length of the roller of hydraulic jump, decrease in the secondary depth of the hydraulic jump, and the required tailwater depth. Also, the optimal distance of two perforated sills from the beginning of the stilling basin with a fixed height ...
Open wound managment after perforated appendicitis has been a common practice but recently, primary closure has been advocated to reduce costs and morbidity. For comparing delayed closures against primary closure with vacuum drainage, a randomized experimental study was designed. in Kerman. Sixty patients with perforated appendicitis divided randomly in two groups and evaluated on day of discha...
At the onset of a miniaturized device era, several promising methods, primarily wet have been developed to attain large-scale assemblies microparticles. To improve speed, versatility and robustness current methods for structured assembly microparticles, an automatable method capable forming 2D arrays microspheres on large silicon surfaces is devised. The uses perforated with vacuum-suction hole...
a modified electrode was prepared by modification of the carbon paste electrode (cpe) with graphene nano-sheets. the fabricated modified electrode exhibited an electrocatalytic activity toward gallic acid (ga) oxidation because of good conductivity, low electron transfer resistance and catalytic effect. the graphene modified cpe had a lower overvoltage and enhanced electrical current respect to...
Theories of the acoustic impedance of micro perforated panels and membranes for normally incident waves have been well developed for decades. These theories are mainly based on the assumption that the particle velocity at the boundary of the hole wall is equal to zero. This assumption is valid when the panel/membrane is massive and does not vibrate. This paper aims to investigate the effects of...
Perforated NEC in the fragile, premature infant remains a complex neonatal and surgical problem. Future investigation into the basic mechanisms of the intestinal inflammatory response in the premature neonate may allow for preventive strategies in the management of NEC. Until then, surgical management for perforated NEC will remain a necessary intervention to treat the complications of this dis...
This study evaluated bacterial etiology and antibiotic susceptibility in patients diagnosed with community-acquired perforated appendicitis over a 12-year-period. We retrospectively reviewed records of adult patients diagnosed with perforated appendicitis at an 800-bed teaching hospital between January 2000 and December 2011. In total, 415 culture-positive perforated appendicitis cases were ana...
BACKGROUND In 2005, The Danish National Indicator Project (DNIP) reported findings on patients hospitalized with perforated ulcer. The indicator "30-days mortality" showed major discrepancy between the observed mortality of 28% and the chosen standard (10%). RATIONALE An audit committee was appointed to examine quality problems linked to the high mortality. The purpose was to (i) examine pati...

Preliminary note Uniformity of the radial air jet issuing from the ceiling vortex diffuser with side entry plenum box was investigated experimentally. Two different cases of diffuser plenum box design were used: plenum box with perforated plate and plenum box without perforated plate. Air jet velocities were measured under isothermal conditions circumferentially around a diffuser. It was found ...
