A Study of Variations in Radial Wrist Extensors

open access: yesNational Journal of Clinical Anatomy, 2019
Abstract Background and Aim Supernumerary muscles and tendons from extensor carpi radialis longus (ECRL) and extensor carpi radialis brevis (ECRB) are sometimes encountered during hand surgery. They include accessory muscles like extensor carpi radialis intermedius (ECRI), intertendinous slips (ITS) between the two muscles, or simple ...

Gas and Stellar Motions and Observational Signatures of Co-Rotating Spiral Arms [PDF]

open access: yes, 2014
We have observed a snapshot of our N-body/Smoothed Particle Hydrodynamics simulation of a Milky Way-sized barred spiral galaxy in a similar way to how we can observe the Milky Way. The simulated galaxy shows a co-rotating spiral arm, i.e.

Quantitative evaluation of rock brittleness and fracability based on elastic-wave velocity variation around borehole

open access: yesPetroleum Exploration and Development, 2016
Brittleness and fracability are two important rock properties in hydraulic fracturing of unconventional reservoirs. Based on the variation of compressional and shear velocity around borehole using acoustic measurement, an effective technique is developed

Measuring radial flow of partonic and hadronic phases in relativistic heavy ion collision

open access: yes, 2009
It has been shown that the thermal photon and the lepton pair spectra can be used to estimate the radial velocity of different phases of the matter formed in nuclear collisions at ultra-relativistic energies.

Four patients with a clinically significant radial artery anomaly

open access: yesJournal of Vascular Surgery Cases and Innovative Techniques, 2019
The superficial radial artery is an anatomic variant in which the radial artery passes superficial to the tendons of the anatomic snuffbox. Cadaver studies have shown its incidence to be 0.5% to 1%.

Hypoplastic and Accessory Radial Arteries: A Case Report [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Arterial variations in the upper extremity occur in a high prevalence. The radial artery is a terminal branch of the brachial artery in the cubital fossa. This artery is used in some treatment interventions and it’s variation is important for clinicians.
