Introduction: The brachial plexus is responsible for the innervation to the upper limb and some parts of the thorax. Variations in the branching of the brachial plexus are common and have been reported in 65.3% of the population. The variations (Atypical communication) of brachial plexus have significant clinical and surgical importance. Methods: In this study 10 upper limbs which belonged...

in this paper we consider several generalizations of the skew t-normal distribution, and some of their properties. also, we represent several theorems for constructing each generalized skew t-normal distribution. next, we illustrate the application of the proposed distribution studying the ratio of two heavy metals, nickel and vanadium, associated with crude oil in shadgan wetland in the south-...

The involvement of elements in the pathological process of primary hypertension has been established. The serum levels of copper, iron, zinc, sodium, potassium and calcium were studied by atomic absorption spectrophotometery and flame photometry in hypertensive and normal subjects. Serum copper and zinc levels were increased in hypertensive patients (25.5% and 14.7% respectively) as compar...

Pressure shear plate impact tests have revealed that when normal stress changes rapidly enough, the frictional resistance is no longer proportional to but rather evolves with slip gradually. Motivated by these findings, we focus on characterizing dynamic strength of interfaces subject rapid variations in stress. To study this problem, use laboratory experiments featuring cracks interacting a fr...

Abstract On 2019 January 8, the Telescopic Optical Navigation Camera (ONC-T) on board Hayabusa2 spacecraft observed Cb-type asteroid 162173 Ryugu under near-opposition illumination and viewing conditions from approximately 20 km in distance. Although opposition observations have never been used for mapping purposes of a planetary body, we found three advantages these conditions: (1) images are ...
