Consider an orthogonal polyhedron, i.e., a polyhedron where (at least after a suitable rotation) all faces are perpendicular to a coordinate axis, and hence all edges are parallel to a coordinate axis. Clearly, any facial angle (i.e., the angle of a face at an incident vertex) is a multiple of π/2. Also, any dihedral angle (i.e., the angle between two planes that support to faces with a common ...

a 26 year old woman attended to our hospital with multifocal giant cell tumor in different sites, one in distal end of right radius with aggresive behavior and amputation of the mid forearm and the second in the head of the right humerus with benign and non aggresive clinical appearance.

PURPOSE OF THE STUDY The aim of this study was to evaluate comparatively the outcomes of pediatric displaced supracondylar fractures of humerus which were treated with either closed reduction and percutaneous pinning (CRPP) or open reduction and percutaneous pinning (ORPP). MATERIAL AND METHODS The study included 100 children with displaced supracondylar fractures of the humerus, who were tre...

The reference to ethnicity in the 2012 National Suicide Prevention Strategy for England (1) is mainly with regard to promoting mental health in Black and Minority Ethnic (BME) groups. However, there is little detailed information about any specific strategy to reduce suicide rates in BME groups. The Suicide Prevention Strategy and Action Plan for Northern Ireland has only one brief reference re...

background and objective: cerebral arteriovenous malformation (cavm) hemodynamic is disease condition, results changes in the flow and pressure level in cerebral blood vessels. measuring flow and pressure without catheter intervention along the vessel is big challenge due to vessel bifurcations/complex bifurcations in arteriovenous malformation patients. the vessel geometry in cavm patients are...

introduction the brachial plexus, a complex network of nerves, innervates to the upper limbs. variation in the course of the nerves in the upper limb is common. case presentation this paper describes two cases of upper limb variations in a cadaver dissected at lorestan university of medical sciences. in the first variation, the median nerve in the arm has a different route, so that the median m...

The purpose of this research is to test the experimental conditions which lead to the best determination of the glenohumeral joint rotation centre in vivo with two shoulder circumductions (30°,130° abduction) and two relative displacements (humerus with respect to scapula or clavicle). Nine subjects perform circumduction movements of small magnitude. Three functional methods were used to estima...
