abu al-qasim khalaf ibn-e-abbas zahrawi(936-1013 a.d.), known as albucasis in west, was one of the greatest physicians in the islamic world. to many historians, he was considered as the father of modern surgery. his book, al-tasrif, e.g., written in 30 chapters, was, in fact, a medical encyclopedia of that era. it was used as one of the main references in medical academic centers for centuries....

dN The field scattered by an antenna contains a component that is the short circuit scattered field normalized by the short circuit current, and a second component that ls the radiation field normalized by the transmitting current and multiplied by a factor (1 r). RCS is the magnitude squared of the difference between two terms, one being the square root of a complex "structural" cross section,...

Localized surface plasmon resonances (LSPRs) in metallic nanostructures have been studied intensely in the last decade. Fano interference is an important way to decrease the resonance linewidth and enhance the spectral detection resolution, but realizing a Fano lineshape with both a narrow linewidth and high spectral contrast-ratio is still challenging. Here we propose a metallic nanostructure ...

Background: Renal osteodystrophy (ROD) is a common bone and mineral metabolism disorder in patients with end-stage renal disease (ESRD). This study aimed to determinate the frequency of the subtypes of ROD and evaluate the diagnostic value of biochemical as the well as radiographic markers for the diagnosis of ROD among hemodialysis patients in Golestan province of Iran.  Materials and Methods...

This article addresses the dynamic modeling of geometrically exact sliding Cosserat rods. Such systems need to consider non-material time-varying domains which Lagrangian view point solid mechanics is inappropriate. In here presented, we use model inextensible Kirchhoff rods along a domain whose time variations are not necessarily imposed but governed by dynamics, i.e. depend on configuration r...

The transmission properties of a guide consisting of a dielectric rod of rectangular cross-section surrounded by dielectrics of smaller refractive indices are determined. This guide is the basic component in a new technology called integrated optical circuitry. The directional coupler, a particularly useful device, made of two of those guides closely spaced is also analyzed. [The SCI indicates ...
