[ 1 ] - Spirometric Parameters: Hemodialysis Compared to Peritoneal Dialysis
Introduction: Renal failure affects the mechanical and the ventilatory function of the lungs. A few studies have evaluated the ventilatory and pulmonary function in dialysis patients. The present study aimed to compare Pulmonary Function Test (PFT) results in patients undergoing Hemodialysis (HD) and Peritoneal Dialysis (PD). Materials and Methods: We conducted a cross-sectional study on 50 pa...
[ 2 ] - Monte Carlo Simulation of Electron Beams produced by LIAC Intraoperative Radiation Therapy Accelerator
Background: One of the main problems of dedicated IORT accelerators is to determine dosimetric characteristics of the electron beams. Monte Carlo simulation of IORT accelerator head and produced beam will be useful to improve the accuracy of beam dosimetry.Materials and Methods: Liac accelerator head was modeled using the BEAMnrcMonte Carlo simulation system. Phase-space files were generated at...
[ 3 ] - The effect of injection parameters on dimensional accuracy of wax patterns for investment casting
Thermal expansion and hot deformation are two phenomena causing dimensional errors in investment casting. This error occurs in dimensions between the die and wax pattern. Therefore, the wax's thermo-physical and thermo-mechanical properties, the metal die features, and the process parameters affect the dimensions of the wax pattern. Some important effective process parameters are the injection ...
