INFLUENCE OF SOME PROCESS INPUT FACTORS ON THE SURFACE ROUGHNESS AMPLITUDE PARAMETERS AT EDM WHEN USING TUBULAR TOOL ELECTRODES

INFLUENCE OF SOME PROCESS INPUT FACTORS ON THE SURFACE ROUGHNESS AMPLITUDE PARAMETERS AT EDM WHEN USING TUBULAR TOOL ELECTRODES

The electrical discharge machining could be used sometimes to improve the roughness of the machined surfaces.The values of the surface roughness parameters are affected by the characteristics of the electrical discharges developed between the closest asperities existing on the active surface of the tool electrode Full TOB Set and on the workpiece s

Modified high-flow nasal cannula oxygen therapy versus conventional oxygen therapy in patients undergoing bronchoscopy: a randomized clinical trial

Abstract Background Hypoxemia frequently occurs during bronchoscopy.High-flow nasal cannula (HFNC) oxygen therapy may be a feasible alternative to prevent the deterioration of gas exchange during bronchoscopy.With the convenience of clinical use in mind, we modified an HFNC using a single cannula.This clinical trial was designed to test the hypothe
