November 1998 2 medicamundi X-ray examinations of the skeleton are, after chest exposures, the most frequently performed type of radiological examination, representing about 30 % of the total. With a few exceptions, projection radiography forms the basis for the diagnosis of skeletal disorders and, in most cases, provides the information for the definitive diagnosis. In traumatology, rheumatolo...

This paper examines the properties of two Internet pricing systems – a flat rate and a usage-based pricing system – in terms of the social welfare, by generalizing the theory advocated by the scholars. This study contributes not only to the systematic generalization of the theory but also to the examination of the waste of resource innate in the flat rate tariff. We found that the superiority b...

Nonthermal radio emission in the galactic center reveals a number of vertical structures across the galactic plane, which are attributed to poloidal magnetic field and/or energetic outflow. Thermal radio emission comprises star forming regions distributed in a thin, dense thermal gas disk. The thermal region is associated with dense molecular gas disk, in which the majority of gas is concentrat...

The receptivity of a hypersonic boundary layer to three-dimensional wall perturbations is investigated in this paper by numerical simulations. The work is motivated by Tumin’s [1] theoretical analysis on the receptivity of compressible boundary layers to three-dimensional wall perturbations with the help of the biorthogonal eigenfunction system. Specifically, receptivity processes of a Mach 5.9...

in this paper, the effect of cyclic loading on punching strength of flat slabs strengthened with carbon fiber reinforced polymer (cfrp) sheets is studied. experimental results of ten slab specimens under monotonic and cyclic loading are analyzed. eight specimens were strengthened with cfrp sheets on the tensile face of the slabs and the two other specimens were kept un-strengthened as control s...

In this work, an equivalent continuum of a barrel gridshell is introduced. Constitutive identification procedures based on periodic homogenization are provided in the literature for purpose, flat Representative Element Volume (REV), notwithstanding that geometry structures concerned curved. Therefore, novelty present study selection curved REV to obtain elastic constants. The numerical validati...

Semiconductor blue laser diode was used for crystallization annealing of amorphous silicon backplane flat panel display. The grain size result crystal can be controlled by beam intensity or scanning speed. poly produced BLDA showed same characteristics as ELA in LTPS. Lateral have been BLDA, its field mobility is three times higher than ELA. A multiple head equipment proposed, which high perfor...
