Variations of the radial artery in man

Surgical and Radiologic Anatomy, 2001
Variations 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 ...

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

Radial yield variations in semiconductor wafers

IEEE Circuits and Devices: the Magazine of Electronic and Photonic Systems, 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.

Common variations of the radial wrist extensors

The Journal of Hand Surgery, 1978
An 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, 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.

Variation of Radial Elasticity in Multiwalled Carbon Nanotubes

Nano Letters, 2007
Correlations 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
