conclusions hematoma block analgesia used in distal radius fractures of the elderly is a very safe and effective method that seems preferable to general anesthesia in emergency departments. objectives the aim of this study was to compare two analgesia methods including hematoma block and general anesthesia in people over 60 years in the orthopedic emergency department. methods 68 elderly patien...

We investigate, at both zero and finite temperature, the properties of strangelets versus the electric charge Z and strangeness S. The strangelet radius is not a monotonic function of either charge or strangeness, and a minimum is reached in the (Z, S) plane. However, the thermodynamically stable strangelets do not correspond to the radius minimum. The minimum radius always appears at positive ...

We prove that given a fixed radius r, the set of isometry-invariant probability measures supported on “periodic” radius-r sphere packings in hyperbolic space Hn is dense in the space of all isometry-invariant probability measures on the space of radius-r sphere packings when n = 2, 3. By a periodic packing, we mean one with cofinite symmetry group. As a corollary, we prove the maximum density a...

We present the results from a survey of 57 low-redshift Abell galaxy clusters to study the radial dependence of the luminosity function (LF). The dynamical radius of each cluster, r200, was estimated from the photometric measurement of cluster richness, Bgc. The shape of the LFs are found to correlate with radius such that the faint-end slope, α, is generally steeper on the cluster outskirts. T...

The length function lq(r,R) is the smallest length of a q-ary linear code of covering radius R and codimension r. New upper bounds on lq(r, 2) are obtained for odd r ≥ 3. In particular, using the one-to-one correspondence between linear codes of covering radius 2 and saturating sets in the projective planes over finite fields, we prove that

We prove new inequalities for the spectral radius, essential operator norm, measure of noncompactness and numerical radius Hadamard weighted geometric means positive kernel operators on Banach function sequence spaces. Some extend refine known that have been established by several authors relatively recently. Several appear to be even in finite dimensional case.

The new method proposed in this work not only measures the particle size distribution and the average molar mass accurately using the static light scattering (SLS) technique when the Rayleigh-Gans-Debye approximation is valid for dilute poly-disperse homogenous spherical particles in dispersion, but also enables us to have insight into the theoretical analysis of the dimensionless shape paramet...
