Radial electron heat transport in low collisionality, magnetically-confined toroidal plasmas is shown to result from paleoclassical Coulomb collision processes (parallel electron heat conduction and magnetic field diffusion). In such plasmas the electron temperature is equilibrated along magnetic field lines a long length L (>> periodicity length πR0q), which is the minimum of the electron coll...
Radial forging is an open die forging process used for reducing the diameters of shafts, tubes, stepped shafts and axles and also for creating internal profiles such as rifling the gun barrels. The radial forging of tube is usually performed over a mandrel to create an internal profile and/or size the internal diameter. Most of the previous studies conducted on the radial forging process have u...
A newly patterned electrode is designed for a dielectric liquid lens. The electrode has a radial interdigitated structure which can provide a symmetrical-nonuniform fringing field. This electric field can effectively deform the shape of a dielectric liquid droplet in radial direction, causing the focal length of the liquid droplet to change. For a lens using glycerol as the droplet and optical ...
Introduction: Several studies have investigated differences in quantitative morphological features between benign and malignant breast tumors, as assessed by dynamic contrast enhanced-MRI (DCE-MRI); however, very little information is available on the extent of such differences between certain subgroups of malignant tumors, such as hormone receptor positive and negative tumors. Such information...
Global gyrokinetic particle simulation and nonlinear gyrokinetic theory find that electron temperature gradient sETGd instability saturates via nonlinear toroidal coupling, which is a nonlocal interaction in the wave vector space that transfers energy successively from unstable modes to damped modes preferentially with lower toroidal mode numbers. The electrostatic ETG turbulence is dominated b...
This article focused on the stress analysis of an edge crack in a thin hallow rotating functionally graded material (FGM) disk. The disk is assumed to be isotropic with exponentially varying elastic modulus in the radial direction. A comprehensive study is carried out for various combinations of the crack length and orientation with the different gradation of materials. The effect of non-unifor...
background: the purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis. methods: this is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. the average time between implantation and removal was 23 month...
BACKGROUND Osteointegration of press-fit radial head implants is achieved by limiting micromotion between the stem and bone. Aspects of stem design that contribute to the enhancement of initial stability (ie, stem diameter and surface coating) have been investigated. The importance of total prosthesis length and level of the neck cut has not been examined. METHODS Cadaveric radii were implant...
The radial scale length of the exponential component of the disc of the Milky Way has been determined in the near infrared. We have used the TMGS (Two Micron Galactic Survey) database which contains positions and K-magnitudes of about 700.000 stars distributed in serveral regions along the galactic plane. From those we have selected areas more than 5 off the plane to minimize the effect of exti...
