Bilateral variation in radial bone speed of sound

European Radiology, 2004
The aims of this study were to: (a) examine differences in speed of sound (SOS) between the right (SOS(R)) and left (SOS(L)) radius; (b) detect bone loss following proximal forearm fracture by SOS measurement at the radius; and (c) compare SOS(L) and bone mineral density (BMD) of one-third, mid-distal, ultra-distal and total region of the left radius ...

Variations of the radial recurrent artery of clinical interest

Surgical and Radiologic Anatomy, 2013
The anatomy of the radial recurrent artery (RRA) is important for different clinical procedures: interventional cardiology and microsurgery of the forearm; however, few studies have analysed its morphology: number, course, relations and distribution.The RRA was analysed in 332 upper limbs divided into two groups: (1) normal pattern of the arterial axis

On the Mean Radial Variation of the Globe

Quarterly Journal of the Geological Society of London, 1895
The Author submits considerations (chiefly derived from the characters of the earlier sediments) which lead him to suppose that crust-folds have not been produced by continuous contraction of the Earth, and that the planetary heat and mean radius of the Earth have been practically invariable during the period which has elapsed since Cambrian times.

Diurnal Variation in Vision After Radial Keratotomy

American Journal of Ophthalmology, 1989
We tested eight patients who had undergone radial keratotomy with regard to refraction, keratometry, corneal thickness, and intraocular pressure one to two weeks after surgery. Patients were examined immediately after eye-lid opening at 7:30 A.M. and again at 4:00 P.M. The contralateral eye was used as a control.

Radial variation of functions in Dirichlet‐type spaces

Mathematika, 1997
Let \(W\) be a positive, increasing and continuous function on \([1,\infty)\) for which (1) \(\sum (W(n))^{-1} =\infty\). A function \(H\) is defined initially on \((0,\pi)\): \[ H(x)= \int_1^{\pi/x} \bigl(W(t) \bigr)^{-1} dt+ \int_1^{\pi/x} \bigl(W (t)\bigr)^{-1 /2} dt\int^\infty_{\pi/x} t^{-1} \bigl(W(t) \bigr)^{-1/2}dt, \] and then extended as an ...

Radial and Tangential Variation of Deuterium in Hailstones

Journal of the Atmospheric Sciences, 1975
Abstract Radial variations of deuterium content are measured in nine large hailstones from three storms; of tritium content in one of the nine; and tangential variations of deuterium content in a wet-growth layer in five of the nine. Crystal size and air bubble content are noted as well.

Effects of radial conductivity variation on the Ponomarenko dynamo

Physical Review E
We study the effects of conductivity variation on the Ponomarenko dynamo. Taking monotonically increasing, decreasing and sinusoidally varying radial profiles, we study the kinematic dynamo problem. The threshold of the dynamo, given by the critical magnetic Reynolds number Rm_{c}, is found to strongly depend on the form of conductivity variation near ...

Radial porosity variations in packed beds

AIChE Journal, 1958
AbstractThe radial variation of void fraction in randomly packed beds of spheres, cylinders, Raschig rings, and Berl saddles was investigated. After packing, the beds were filled with paraffin, which was then allowed to solidify. Slabs were cut from the bed, and annular rings were removed by two different experimental techniques.

Radial yield variations in semiconductor wafers

Microelectronics Reliability, 1987
Detailed examination of yield data from several different products in two different technologies and two different wafer sizes has shown a pronounced radial dependence. In all cases, the yield profile has a distinct knee starting at about 10 mm from the wafer periphery, dropping steeply within the final 5 mm.

Radial variation of track damage in polycarbonate

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2004
Abstract Several authors reported data showing a differentiated structure of ion tracks in some polymers, when analysed at submicroscopic level. Four zones can be distinguished: core, halo, cross-linking and bulk, at least in tracks produced by ions with specific energies higher than 0.2 MeV/n.
