A quasi-steady-state model of the consequences of rotation on the hydrodynamical structure of a stellar radiative zone is derived by studying in particular the role of centrifugal and baroclinic driving of meridional motions in angular momentum transport. This non-linear problem is solved numerically, assuming axial symmetry of the system, and within some limits it is shown that there exist sim...

We undertook a radiographic analysis with pre-operative computed tomographic myelography in 78 patients with idiopathic scoliosis in order to analyse rotation of the spinal cord and to investigate its clinical significance. The angle of rotation of the cord had a statistically significant relationship to both that of the apical vertebra and the size of the primary curve. The relationship betwee...

There is a self-similar solution for the stability limits of long, almost cylindrical liquid bridges between equal disks subjected to both axial and lateral accelerations. The stability limits depend on only two variables; the so-called reduced axial, and lateral Bond numbers. A novel experimental setup that involved rotating a horizontal cylindrical liquid bridge about a vertical axis of rotat...

INTRODUCTION: The current study compared in-vitro tibiofemoral axial rotational constraint between 2 posterior stabilized mobile-bearing knee prosthesis and their fixed-bearing counterparts. It was demonstrated that both mobile-bearing knees induced significantly less constraint torque compared to their fixed-bearing counterparts. Highly-constrained design of the fixed-bearing knees substantial...

developed whose read/write characteristics are comparable to 1.2-mm-thick optical disks. The development difficulty of the thin optical disks was the achievement of stable rotation equivalent to 1.2-mm-thick optical disks. This report presents the results of studies conducted to improve the axial accelerations of thin optical disks on 8× speed (27.92 m/s) based on the digital versatile disc rec...

Long radiographs are used to measure lower limb axial alignment, to assess the progression of deformity, and to plan corrective surgery. The purpose of this study was to test the belief that jigs are necessary in order to control limb position for radiography. Above-knee amputated limbs were fixed in different positions of rotation and of knee flexion and radiographed to study the effect on the...

The title compound, [CuCl(2)(C(21)H(19)N(3))], lies on a twofold rotation axis that passes through the N(pyrid-yl)-Cu bond; this symmetry element relates one half of the organic ligand to the other as well as one Cl ligand to the other. The three N atoms span the axial-equatorial-axial sites of the trigonal-bipyramidal coordination polyhedron; the geometry of the Cu(II) atom is 31% distorted fr...

We investigate the role of stellar axial rotation on the nitrogen nucleosynthesis at low metallicities Z. For this purpose, we have calculated models with initial masses between 2 and 60 M⊙ at Z=0.00001 from the zero age sequence to the phase of thermal pulses for models below or equal to 7 M⊙, and up to the end of central C–burning for the more massive stars. The models include all the main ph...
