This paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. Different railways use different threshold radius from 91m to 365m to provide restraining rail. These threshold figures are probably experience driven choices. The need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...
background: mal::::union:::: is the most common complication following distal radius fractures. aim of this study was to evaluate the results of distal radius corrective osteotomy and plate fixation by dorsal approach in the mal::::union::::. methods: in this retrospective study, 14 patients with neglected distal radius mal::::union:::: from 2005 to 2011 were studied. all patients were treated ...
the average distance of a vertex $v$ of a connected graph $g$is the arithmetic mean of the distances from $v$ to allother vertices of $g$. the proximity $pi(g)$ and the remoteness $rho(g)$of $g$ are defined as the minimum and maximum averagedistance of the vertices of $g$. in this paper we investigate the difference between proximity or remoteness and the classical distanceparameters diameter a...

the center (periphery) of a graph is the set of vertices with minimum (maximum)eccentricity. in this paper, the structure of centers and peripheries of some classes ofcomposite graphs are determined. the relations between eccentricity, radius and diameterof such composite graphs are also investigated. as an application we determinethe center and periphery of some chemical graphs such as nanotor...
Classic treatment of galeazzi fracture-dislocation in adults is open radius reduction o radius fracture and closed reduction of distal radioulnar Joint. In this two cases, fracture occurred in distal third radius and treated by closed method. Reduction was anatomic and postoperative and late results was good.
In this work, the effects of inner radius and width variation on energy spectrum and persistent current in hexagonal graphene quantum rings with zigzag edges have been studied by using the tight-binding model. Our investigation show that the energy spectra of these rings are grouped into subbands which each one consists of six coupled energy levels that separated by energy gaps. The pattern o...

background: considering the importance of an early diagnosis and proper decision-making in regards to the treatment of pediatric distal radius and elbow fractures, this study examines emergency medicine specialists’ accuracy in the diagnosis and treatment of these patients. methods: from 2012 and 2013, children less than 14 years old who were referred to an academic hospital emergency departmen...
