BACKGROUND The management of distal radial fractures is guided by the interpretation of radiographic findings. The aim of this investigation was to determine the intra- and inter-observer reliability of eight traditionally reported anatomic radiographic parameters in adults with an acute distal radius fracture. METHODS Five observers participated. All were routinely involved in making treatme...

Two sets of silicon wafers were implanted with 60 keV arsenic ions at a dose of 5x1015 cm-2, using an Applied Materials SWIFT implanter. The first batch consisted of five silicon preamorphised wafers, whilst the second batch was implanted under the same conditions into <100> single crystal wafers. The tilt angle was varied over the range 0o 45o. After implantation the samples were cut into smal...

BACKGROUND The various measurements of patellar tilting failed to isolate patellar tilting from the confounding effect of its neighboring bone rotation (femoral and tibial rotation) in people sustaining patellofemoral pain (PFPS). Abnormal motions of the tibia and the femur are believed to have an effect on patellofemoral mechanics and therefore PFPS. The current work is to explore the various ...

[1] Using line‐of‐sight measurements of horizontal plasma drift from the Super Dual Auroral Radar Network (SuperDARN) located in the Northern and Southern hemispheres over a period extending from 1998 to 2002, statistical models of the high‐latitude convection electric field are derived for various ranges of interplanetary magnetic field (IMF) magnitude and orientation and for several ranges of...

INTRODUCTION Most computer-assisted navigation systems used in total hip arthroplasty (THA) reference the anterior pelvic plane, which connects the anterior superior iliac spines and the pubic symphysis. The pelvic tilt is defined as the angle between this anterior pelvic plane (APP) and a vertical line in the standing position. Important interindividual variations of this angle have been repor...

background: abnormal angulation of the lunate can be an indication of intercarpal pathology. on magnetic resonance images (mris) the lunate often looks dorsally angulated, even in healthy wrists. the tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. the primary aim of this study was to deter...

The significance of tilt anisoplanatism is established, and a measurement theory, based on aperture-averaging intensity scintillation, is developed. The theory is a direct extention of the technique currently used to determine the isoplanatic angle as defined by Fried [J. Opt. Soc. am. 72, 52 (1982)]. By using this theory, a physically realizable binary aperture-weighting function is derived fo...

Measurements of the circular polarization of Balmer-u radiation emitted by excited hydrogen atoms, following the transmission of (20—50)-keV protons through thin, tilted amorphous carbon foils, exhibit markedly unexpected behavior as a function of exposure of the foil to the proton beam. Specifically, the circular polarization changes from an initially well understood tilt-angle dependence to a...

Electron tomography can provide three dimensional (3D) visualization of nanoscale objects in a transmission electron microscope (TEM) from a tilt series of projected images. The accuracy of the 3D reconstruction depends on quality of input parameters, including accurate alignment in real space and accuracy of tilt and azimuth angle measurements. Here we present an electron diffraction-based in-...
