This paper presents a hydrodynamic lubrication model to investigate the static and dynamic characteristics of micro-grooved bearings considering journal misalignment. An averaged Reynolds equation with mass conservation is derived numerical procedure solved by finite difference method. The influences eccentricity ratio, misalignment micro-groove parameters on performances aligned/misaligned are...

OBJECTIVE To obtain reference values, to suggest optimal recording and stimulation site for radial motor nerve conduction study (RmNCS), and to analyze the correlation among RmNCS parameters, demographics and ultrasonography (US) findings. METHODS A total of 55 volunteers participated in this study. We hypothesized that 'lateral edge of spiral groove (A)' was the optimal stimulation site, and...

Spiral groove entrapment neuropathy is a compression that can occur for various reasons due to the superficial course of radial nerve at level spiral groove. Since repetitive movements play role in development mechanism neuropathy, compelling and triceps muscle may predispose neuropathy. In this case, 61-year-old male patient who developed low hand after long-term use lawnmower presented. The w...

Purpose: A simple method for verifying the dose point kernel of Ir-192 source used in HDR brachytherapy using Kodak EDR2 film in a spiralphantom. Method and Materials: A spiral solid water phantom availablefrom Gammex International for IMRT QA was modified for this study. A CT scan image of the phantom was acquired with a 10 x 12 inch filmloaded in the spiral groove. A 3.5 mm long 8...
