The aim of this paper is to investigate the ability of various site‐condition proxies (SCPs) to reduce ground‐motion aleatory variability and evaluate how SCPs capture nonlinearity site effects. The SCPs used here are time‐averaged shear‐wave velocity in the top 30 m (VS30), the topographical slope (slope), the fundamental resonance frequency (f0) and the depth beyond which Vs exceeds 800 m/s (...
Modern geographic information system (GIS) tools have allowed a more careful examination of how the physical characteristics of a property’s neighborhood and surrounding land uses are capitalized into property values. The ArcGIS Viewshed tool is a case in point: it identifies the cells in an input raster that can be seen from one or more observation points. In this study, we use the tool in a h...
TiO2 nanorods are synthesized by a thermal corrosion. In present work, synthesis of TiO2 nanorods in anatase, rutile and Ti8O15 phases, by using the sol-gel method and alkaline corrosion are reported. The morphologies and crystal structures of TiO2 nanorods are characterized by use of field emission scanning electron microscopy, atomic force microscopy and X-ray diffractometer techniques. The o...
Background and Aim: Bleaching products as chemical materials can exert side effects on soft and hard tissues and existing restorative materials with oxidizing mechanism. The aim of this study was to evaluate the effect of 15% and 35% carbamide peroxide gels as home and in-office bleaching agents respectively, on microhardness and surface topography of composite resin.Materials and Methods: In t...
