PURPOSE We hypothesized that radial shortening osteotomy (radial shortening) for skeletally immature patients with Kienböck's disease would induce overgrowth of the radius. The purpose of this study was to determine the effect of radial shortening on radial growth in skeletally immature patients with Kienböck's disease and to clarify the relationship between the postoperative growth alterations...

Robust thermal dissipation sensors of variable length (3 to 30 cm) were developed to overcome limitations to the measurement of radial profiles of sap flow in large-diameter tropical trees with deep sapwood. The effective measuring length of the custom-made sensors was reduced to 1 cm at the tip of a thermally nonconducting shaft, thereby minimizing the influence of nonuniform sap flux density ...

BACKGROUND The effectiveness of excision of osteochondromas in controlling the progression of forearm and wrist deformity remains an issue of controversy. The purpose of this study was to analyze the effectiveness of tumor excision in the correction of forearm and wrist deformity due to multiple osteochondromas in children, with an interpretation of the results based on different patterns of de...

endoscopic radial artery harvesting (erah) is a feasible and attractive minimally invasive approach for conduit procurement, however there have been concerns about a potential neurological damage occurring at the harvest limb site secondary to injury of the radial nerve during endoscopic harvesting. we present a case of erah in which we evaluated intraoperatively the characteristics of radial n...

Introduction Use of nonselective pulses and modulated flip angles (aka SPACE, [2, 3, 4]) in refocusing pulses improves the sampling efficiency in 3D turbo spin echo imaging. Two flexible reordering schemes, the linear mode and the radial mode, have been proposed [1] to circumvent some intrinsic limitations of the rectangular kspace sampling grid (e.g., allowing for flexible k-space coverage) in...

Based on three-dimensional simulations of the Braginskii equations we show that for typical plasmaedge parameters the saturation of electromagnetic toroidal hi mode turbulence is controlled by the selfgeneration and subsequent annihilation of radial magnetic field perturbations. This should be contrasted with the electrostatic limit, where the growth of the linear hi mode is terminated by the o...

PURPOSE Children with radial longitudinal deficiency have very short forearms. The Ilizarov method of distraction osteogenesis has been used to increase extremity length, but results differ with the underlying condition and the limb being lengthened. The purpose of this study is to examine retrospectively the outcomes of Ilizarov lengthening of the ulna in children with radial longitudinal defi...

BACKGROUND Radial artery (RA) was the second arterial graft introduced in clinical practice for myocardial revascularization. The skeletonization technique of the left internal thoracic artery (LITA) may actually change the graft's flow capacity with potential advantages. This leads to the assumption that the behavior of the RA, as a coronary graft, is similar to that of the LITA, when skeleton...

In this paper, a novel integrated structure is proposed in order to reduce the axial length of the high speed of a magnetically suspended motor (HSMSM) to ensure the maximum speed, which combines radial displacement sensor probes and the permanent magnet biased radial magnetic bearing in HSMSM. The sensor probes are integrated in the magnetic bearing, and the sensor preamplifiers are placed in ...

The effects on small format photogrammetry of radial and decentering distortion, variations in focal length and film unflatness are reviewed. The results of recent experiments with these parameters are described. The experiments have concentrated on the use of small non-metric cameras and the results are analysed to indicate the magnitude of errors which can be introduced to analytical and ster...
