conclusions the outside diameter/inside diameter ratio at the metaphyseal/diaphyseal junction of the distal radius on ap radiographs is suitable for use as a predictor of distal-radius bone density. further studies should be performed, and clinical utility evaluated. results the mean bmd was 0.559 (sd = 0.236) g / cm2. the mean outside diameter/inside diameter ratio was 1.24 (sd = 0.013); the r...

  Background: Considering the importance of an early diagnosis and proper decision-making in regards to the treatment of pediatric distal radius and elbow fractures, this study examines emergency medicine specialists’ accuracy in the diagnosis and treatment of these patients. Methods: From 2012 and 2013, children less than 14 years old who were referred to an academic hospital emergency departm...

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...

Wind power forecasting is pivotal in optimizing renewable energy generation and grid stability. This paper presents a groundbreaking optimization algorithm to enhance wind through an improved al-Biruni Earth radius (BER) metaheuristic algorithm. The BER algorithm, based on stochastic fractal search (SFS) principles, has been refined optimized achieve superior accuracy prediction. proposed denot...

Two ways have been suggested for using the magnetic field of a planet to estimate the radius of its electrically conducting core, assumed spherical and concentric with the planet's surface. In the frozen flux method, the core radius is assumed to have the value rFF for which the integrated unsigned radial magnetic flux, from the sphere of that radius, is most nearly constant in time. In the fla...

BiFeO3 is an interesting material due to its multiferroic properties. It attracts attention potential applications in spintronics and microelectronics for data storage, among others. Single-phase bulk from difficult synthesize. The kinetics of perovskite phase formation most often leads the presence impurity phases. has been shown that low levels replacement Bi with rare earth ions lead stabili...

We present a systematic study of the complexation of the new pseudopeptidic ligand isophthaloylbisglycine (H(2)IBG) with divalent metal ions of varying ionic radius. This work represents the initial employment of H(2)IBG in the coordination chemistry of alkaline earth, 3d transition, Zn(II) and Cd(II) metal elements. Infrared, NMR, thermal, magnetic, adsorption and theoretical studies of these ...

one of the most important problems in geodesy is the unification of height datum. generally in geodesy; there are two types of height systems, the geometrical height based on ellipsoid and the physical height based on gravity-defined surface (zhang et al, 2009).local height datum is determined according to mean sea level (msl). in regarding to mismatch of mean sea level and geoid, on the one ha...
