AIM To determine technical considerations and radiographic outcomes of the Synthes volar rim distal radius plate to treat complex intra-articular fractures. METHODS This review highlights technical considerations learnt using this implant since it was introduced in a major trauma unit in November 2011, including anatomical reduction and whether this was maintained radiographically. RESULTS ...

We present spectrophotometry of the eclipsing old nova BT Mon (Nova Mon 1939). By detecting weak absorption features from the secondary star, we nd its radial velocity semi-amplitude to be K R = 205 5 km s ?1 and its rotational velocity to be v sin i = 138 5 km s ?1. We also measure the radial velocity semi-amplitude of the primary star to be K R = 170 10km s ?1. From these parameters we obtain...

– 2 – We present a clear evidence for the motion of the companion star in the Low Mass X-Ray Binary (LMXB) X1822-371. We detect NIII λ4640 emission moving in antiphase with the radial velocity curve of the neutron star and produced on the X-ray heated hemisphere of the donor star. From the motion of this feature we derive a lower limit to the radial velocity semi-amplitude of the companion star...

A number of studies have demonstrated that dorsal cortical comminution (DCC) can predict redisplacement after nonoperative treatment of Colles' fractures; however, the effects of a DCC defect on radiographic outcomes following percutaneous pinning for dorsally displaced extraarticular Colles' fractures are unclear. We, therefore, performed a retrospective study on 85 patients who sustained such...

OBJECTIVES To analyze and correlate the clinical and radiographic results from patients with distal radius fractures who underwent surgical treatment with a fixed-angle volar locked plate. METHODS Sixty-four patients with distal radius fractures were evaluated. They all underwent surgical treatment with a volar locked plate for the distal radius, with a minimum of six months of postoperative ...

Relativistic emission lines generated by thin accretion disks around rotating black holes are an important diagnostic tool for testing gravity near the horizon. The iron K–line is of special importance for the interpretation of the X–ray emission of Seyfert galaxies, quasars and galactic X–ray binary systems. A generalized kinematic model is presented which includes radial drifts and non–Kepler...

In 1989, Semel proposed a new technique (dubbed Zeeman-Doppler imaging or ZDI) for measuring and mapping magnetic fields at the surface of cool active stars from sets of rotationally modulated circularly polarised (Stokes V ) profiles of spectral lines. Two years later, an automatic tool (based on maximum entropy image reconstruction techniques) was developed and checked on a few test cases (Br...

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...

We present spectrophotometry of the eclipsing old nova BT Mon (Nova Mon 1939). By detecting weak absorption features from the secondary star, we find its radial velocity semi-amplitude to be KR = 205± 5 km s −1 and its rotational velocity to be v sin i = 138 ± 5 kms. We also measure the radial velocity semi-amplitude of the primary star to be KR = 170±10km s . From these parameters we obtain a ...

A significant fraction of planetary nebulae (PNe) show jet-like features. These features are usually interpreted as fast collimated outflows, although their true space velocities are uncertain, as their measured radial velocities cannot be properly corrected for projection effects. We have compiled the measured expansion velocities and radial distances of collimated outflows for a sample of 33 ...
