five cases of giant cell tumor of the lower end of radius are reported. three of the patients were women and two were men, the youngest of the patients was 18 years old and oldest 37 years. en bloc resection followed by reconstructive procedures were performed in three of the cases with good results.

The local axisymmetric stability of hydrodynamical and magnetized, nearly-Keplerian gaseous accretion disks around non-rotating black holes is examined in the vicinity of the classical marginally-stable orbit (at radii ∼ R ms). An approximate Paczynski-Wiita pseudo-Newtonian potential is used. Hydrodynamical disks are linearly unstable inside a radius which differs slightly from the classical R...

The problem of target localization with ideal binary detectors is considered in one dimensional space. The problem is investigated in both a censored and non-censored scheme. In the censored setting, the problem is equivalent to estimating the center of a uniform distribution by knowing samples of data. It does not admit an MVU estimator according to the previous results of Lehmann-Sheffe. Howe...

We review current theory, simulation and experiment for the growth of 3D bubbles in ideal dry froth. Theories assume either that the growth rate depends on bubble radius or topology. Radius based laws violate the Young-Laplace law. Topological theories can be either linear or non-linear in the number of faces (f). The growth law can hold either exactly for each bubble (as in 2D) or apply only t...

The thickness, NIR(K) of a knot or link K is defined to be the radius of the largest solid tube one can put around the curve without any self intersections, which is also known as the normal injectivity radius of K. For C1,1 curves K, NIR(K) = min{ 1 2 DCSC(K), 1 supκ(K) )}, where κ(K) is the generalized curvature, and the double critical self distance DCSD(K) is the shortest length of the segm...

Introduction: Scapholunate ligament injury is rare in children. Most of the cases occur with concomitant distal radius fractures. Complete scapholunate disruption may present with long term pain and disability. Case Report: We present a case of scapholunate injury in a youngest patient reported in literature with this injury. The senior author managed the injury with a modified extra-osseous re...

The thickness, NIR(K) of a knot or link K is defined to be the radius of the largest open solid tube one can put around the curve without any self intersections of the normal discs, which is also known as the normal injectivity radius ofK. For C1,1 curvesK, NIR(K) = min{ 1 2 DCSC(K), 1 supκ(K) )}, where κ(K) is the generalized curvature, and the double critical self distance DCSD(K) is the shor...
