results overall, ≥ 2 mm shortening of the radius was seen in 28% of the patients, 53% had 2 - 5 mm radial shortening and 19% of the patients had more than 5 mm shortening of the radius. most of the participants had acceptable outcomes. the mean angulation was 6.28 ± 2.85 degrees and the mean shortening was 3.92 ± 2.22. thirty-nine percent of the patients had an angulation of less than 5 mm, 56%...

Osteoporosis in laying hens has been a production and welfare concern for several decades. The objective of this study was to determine whether differing opportunities for exercise during pullet rearing influences long-term bone quality characteristics in end-of-lay hens. A secondary objective was to assess whether differing opportunities for exercise in adult housing systems alters bone qualit...

The purpose of this study is to investigate the failure sequence of the distal radius during a simulated fall onto an outstretched hand using cadaver forearms and high-speed X ray and video systems. This apparatus records the beginning and propagation of bony failure, ultimately resulting in distal radius or forearm fracture. The effects of 3 different wrist guard designs are investigated using...

Intraosseous schwannoma is a rare benign neoplasm arising from Schwann cells of the nerve sheath and involving the substance of bone. Intraosseous schwannomas account for less than 0.2 % of primary bone tumors. The most common site of occurrence is the mandible, a characteristic traditionally attributed to the long intraosseous path of the inferior alveolar nerve. Here we report a case of intra...

finding a minimum allowable radius length of a circle horizontal curve is essential to reduce earthwork cost or damage to the forest ecosystem, as well as make driving more comfortable. the present study is conducted i) to analyze different radius lengths of circle horizontal curves using an integrated approach consists of a civil3d in concert with the field surveys, and ii) to propose a set of...

field ion microscopy (fim) and scanning tunneling microscopy (stm) have found a wide application in nanotechnology. these microscopes use a metallic nanotip for image acquisition. resolution of fim and stm images depends largely on the radius of nanotip apex; the smaller the radius the higher the resolution. in this research, for tungsten nanotip fabrication, electrochemical etching of tungsten...

osteoporosis diagnosis is usually based on examination of the hip bone and vertebrae density; however, the radius bone has gained attention recently in terms of feasibility and accessibility as it is done by portable devices with proper precision. this study aims to compare hip and spine density with radius, knowing whether radius may be an appropriate alternative for osteoporosis diagnosis. 12...

The Erlang capacity per cell and per unit area in urban code-division multiple-access (CDMA) microcellular environments is evaluated. Special emphasis is given to the effect of breakpoint distance and cell size on the system Erlang capacity. Two different cell plans are considered in which the communication between the base station (BS) and the mobile unit always occurs in a line-of-sight (LOS)...
