Hubble Space Telescope (HST ) observations of the nearby (3.22 pc), K2 V star ǫ Eridani have been combined with ground-based astrometric and radial velocity data to determine the mass of its known companion. We model the astrometric and radial velocity measurements simultaneously to obtain the parallax, proper motion, perturbation period, perturbation inclination, and perturbation size. Because...

We present a combined analysis of previously published high-precision radial velocities and astrometry for the GJ 876 planetary system using a self-consistent model that accounts for the planet-planet interactions. Assuming the three planets so far identified in the system are coplanar, we find that including the astrometry in the analysis does not result in a best-fit inclination significantly...

The aim of this study was to identify possible anatomical risk factors for Kienbock's disease. We measured on a posteroanterior radiograph of the wrist, in zero-position, the Lunate Diameter and Height, Lunate Tilting Angle, Lunate Uncovering Index, Lunate Fossa Inclination, Radial Inclination and Ulnar Variance. We measured these seven parameters on the unaffected hand in the Kienböck group (N...

Recent X-ray observations of microquasars and Seyfert galaxies reveal the broad emission lines in their spectra, which can arise in the innermost parts of accretion disks. Simulation indicates that at low inclination angle the line is registered by distant observer with characteristic two-peak profile. However, at high inclination angles (> 85 •) two additional peaks arise. This phenomenon was ...

BACKGROUND Fractures of distal radius are one of the most common fractures seen by physicians and account for 20% of all fractures seen in the emergency room. Various factors contribute in secondary displacement of fracture fragments after anatomic or near anatomic close reduction and cast immobilization in distal radius fractures. This study was designed to examine the correlation between radi...

AIM To determine the anatomical and functional results of conservative treatment of extra-articular Colles' type fractures of the distal radius and the borderline value of each anatomical parameter for the best possible correlation with functional end result. METHODS This prospective study included 54 patients. Standard radiographs were made of both wrists in two directions after the fracture...

..Objective: To assess the radiological and functional outcome of external fixator in the treatment of intar-articular fractures of distal radius. Study design: Descriptive case series. Place and duration of study: Orthopaedic unit District Headquarter Hospital Temargarha Lower Dir from March 2013 to March 2014. Material and methods: Twenty five patients of intra-articular fracture distal radiu...

UNLABELLED To demonstrate a simple and efficacious option for treating fractures of the distal extremity of the radius using Kirschner wires. METHODS Between September 2008 and April 2009, 48 patients with fractures of the distal extremity of the radius, classified as A3 according to the AO classification, were treated surgically using a modification of the Kapandji technique. RESULTS Out o...

High-inclination circumplanetary orbits that are gravitationally perturbed by the central star can undergo Kozai oscillations—large-amplitude, coupled variations in the orbital eccentricity and inclination. We first study how this effect is modified by incorporating perturbations from the planetary oblateness. Tremaine et al. (2009) found that, for planets with obliquities > 68.875, orbits in t...

BACKGROUND Functional loss is a common complication of the fractured distal part of the radius. The purpose of the present study was to determine if the moment arms of the first dorsal extensor compartment are altered by distal radial fracture malunion. We hypothesized that the moment arms of the abductor pollicis longus and extensor pollicis brevis are significantly affected by dorsal angulati...
