BACKGROUND Although optimal treatment of distal radius fractures is controversial, surgery has gained popularity. The purpose of this study was to evaluate recent trends in the surgical treatment of distal radius fractures in Finns aged 50 years or more. METHODS A nationwide hospital discharge register-based study was conducted among all patients 50 years of age or older who had a surgically ...

The fatigue strength assessment of welded joints by using the known parent material fatigue strength is considered in this paper. The stress concentration factor was determined performing FEA of singlesided transverse attachment joints for mean value of weld toe radius which was calculated by using several measurements of the weld toe radius along the weld length. The fatigue strength of welded...

The intrinsic viscosity [q] and the translational friction coefficientf of polymer molecules in solution are calculated on the basis of the porous sphere model. The only information needed to predict [q] and f is the polymer molecular weight, the radius of gyration in the solvent, and the permeability as a function of position in the “porous sphere.” For systems for which this information is av...

The functional anatomy of the distal radioulnar joint was studied in relation to the whole forearm, using three fresh-frozen, above-elbow amputation specimens. The specimens demonstrate how the proximal and distal radioulnar joints together form a bicondylar joint of special character. The proximal "condyle," the radial head, rotates axially, whereas the distal "condyle," the ulnar head, is fix...

We use the stochastic approach to investigate the measure for slow roll eternal inflation. The probability for the universe of a given Hubble radius can be calculated in this framework. In a solvable model, it is shown that the probability for the universe to evolve from a state with a smaller Hubble radius to that of a larger Hubble radius is dominated by the classical probability without the ...

UNLABELLED The aim of this prospective study was to test a mathematical method of measuring the malrotation of pediatric distal radius fractures (PDRFs) from direct radiographs. A total of 70 pediatric patients who presented at the Emergency Department with a distal radius fracture were evaluated. For 38 selected patients conservative treatment for PDRF was planned. Anteroposterior and lateral ...

Recent papers have presented correlations between the radius of curvature of the anterior lens surface and anterior chamber depth (Lowe, I972), and between the anterior lens radius and the anterior and posterior corneal radius (Lowe and Clark, I973). This paper presents measurements of anterior lens radius in relation to age, lens thickness, and axial length in two series comprising 9I normal e...

METHOD: Halo radius was measured using a vision monitor (MonCv3) with low-luminance optotypes in 39 eyes that had cataract surgery and the bilateral implant of an Acrysof Restor SN6AD1 multifocal IOL or Acrysof IQ monofocal IOL 6 to 9 months previously. The visual angle subtended by the disk halo radius was calculated in minutes of arc (arcmin). Patient complaints of halo disturbances were reco...

The small angle X-ray scattering (SAXS) pattern of the homotetrameric asparaginase II from Escherichia coli was measured in solution in conditions resembling those in which its crystal form was obtained and compared with that calculated from the crystallographic model. The radius of gyration measured by SAXS is about 5% larger and the maximum dimension in the distance distribution function abou...
