This paper presents a method for evaluating the reliability of an in-service highway bridge that considers the resistance capacity loss due to various corrosive environments. To demonstrate the application of the suggested method, a pre-stressed concrete-I (PSC-I) type girder was selected as a sample bridge. An analytical procedure was developed to quantitatively evaluate the performance degrad...

Introduction: The aim of this study was to assess the clinical profile of patients with benign strictures of middle and lower thirds of esophagus , to analyse the grade of dysphagia and site of stricture by barium swallow and to describe the endoscopic and histopathological findings in them Methods: It was a prospective, cross sectional, descriptive study where thirty patients with benign struc...

The metallic corrosion is a spontaneous process that causes damage in almost all sectors of human activity. Among the most affected structures stand out the pipes for oil transportation. The biocorrosion occurs due to the fixation of bacteria, release of metabolites and formation of biofilms that induce or accelerate the corrosion process. Among the groups of bacteria involved in the corrosion ...

The usefulness and applicability of water indices such as Langelier saturation index, Ryznar stability index and Practical scale index for predicting the corrosive/scale forming tendency of chemically treated open recirculating cooling water has been studied. The study is based on the obtained corrosion and scale data for the period from May 1998 to December 2007, carried out at Fast Breeder Te...
