A finite simple graph ? determines a quotient P? of the pure braid group, called graphic arrangement group. We analyze homomorphisms these groups defined by deletion sets vertices, using methods developed in prior joint work with R. Randell. show that, for K4-free ?, product maps is injective, embedding free groups. Then residually free, torsion-free, torsion-free nilpotent, and acts properly o...
This article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. As the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. Four different specimens have been analyzed. These models had some differences such as bolt arrangement and the presence or a...
Background and Aim: The main goal of root canal treatment is to prevent or treat apical periodontitis. The aim of the present study was to assess the coronal restoration status, root canal filling quality, periapical health condition, and related factors in endodontically treated teeth at the Dental Faculty of Islamic Azad University of Medical Sciences, Tehran, Iran, in 2011-12. Materials and...
