Variations of the radial artery in man
Surgical and Radiologic Anatomy, 2001Variations of the radial artery are common in man. A high origin, due either to precocious bifurcation or to persistent duplication of the brachial artery, and the presence of a superficial dorsal ramus in the forearm suggest hemodynamic insufficiency of the axial vascular network allowing persistence of certain portions of the superficial system of ...

Common variations of the radial wrist extensors
The Journal of Hand Surgery, 1978An anatomical study of the extensor carpi radialis longus (ECRL) and brevis (ECRB) in 173 upper limbs demonstrated abnormalities in 50%. Interconnecting tendons between the longus and brevis were found in 35% of limbs, the most common variation (26%) being a tendon arising proximally from the ECRL and inserting distally with the ECRB. In 42 limbs (24%)

Diurnal Variation in Vision After Radial Keratotomy
American Journal of Ophthalmology, 1989We 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.

Variation of Radial Elasticity in Multiwalled Carbon Nanotubes
Nano Letters, 2007Correlations between the local diameter and local radial elastic modulus in multiwalled carbon nanotubes (MWNTs) were investigated via ultrasonic force microscopy. Spatial cross-correlation analysis showed that local radial modulus variations were inversely correlated with local diameter gradients ("bamboo" structures) in MWNTs grown via chemical vapor

Bilateral variation in radial bone speed of sound
European Radiology, 2004The 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 ...

On the Mean Radial Variation of the Globe
Quarterly Journal of the Geological Society of London, 1895The 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.

Variations of the radial recurrent artery of clinical interest
Surgical and Radiologic Anatomy, 2013The 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

Radial voidage variation in CFB risers
The Canadian Journal of Chemical Engineering, 2001AbstractA new correlation for estimating local voidage in CFB risers is provided based on data obtained in a riser of diameter 76 mm and height 6 m using FCC particles at superficial gas velocities between 4 and 8 m/s and solids circulation fluxes up to 425 kg/m2s.
