PURPOSE To evaluate prognostic factors affecting silicone tube intubation outcomes in Asian patients with lacrimal drainage system stenosis. METHODS A retrospective review was conducted on the medical records of 822 patients (1,118 eyes) who had undergone silicone tube intubation to treat lacrimal drainage system stenosis between January 2011 and December 2012. Patients were divided into two ...
PURPOSE We previously described a new procedure specific module (Tube 3) to allow the practice of vesicourethral anastomosis after robot-assisted radical prostatectomy. Herein, we report a predetermined proficiency level of Tube 3 and preliminary validation to explore whether this new module can lead to performance improvement in the da Vinci system. MATERIALS AND METHODS Eight urology reside...
Optimizations on 200 kV electrostatic accelerator have been done in order to increasing ion current on target, improving vacuum condition and reduction in x-rays emission, increasing stability of high voltage power supply and reaching much greater achievable voltage value. The accelerator tube has most important effect on beam tracing in the electrostatic accelerators. So precautions most be co...
Abstract The present study introduces the concept of mitigating pressure pulsations in a hydro-turbine draft tube. refers to using an adjustable guide vane system adjustability relates its ability rotate around axis. test rig for experimental is high-head Francis model turbine. Three sets vanes are distributed evenly circumferentially Each consists two hydrofoils. upper hydrofoil can move lower...
