Introduction It is critical for power plants to continuously monitor corrosive ionic impurities in various plant water streams, such as cooling waters, boiler waters, feed waters, and steam condensates. The presence of impurities above a specified concentration can result in stress-corrosion cracking and other corrosion mechanisms, and therefore have a significant negative impact on power gener...

Fourteen thermotolerant and thermophilic bacterial isolates from a hot spring in Guanajuato State, Mexico, were tested for their ability to induce the corrosion of carbon steel in monocultures and, in selected cases, in mixed cultures and co-culture with a sulfate-reducing strain, SRB-M. Characterization by 16S rDNA showed that three of the thermophilic isolates (G9a, G9c, and G11) belong to th...

BACKGROUND EUS, as it images the full thickness of the gastrointestinal tract wall, could provide more detailed information on benign esophageal strictures. Aim of this study was to evaluate the role of EUS in predicting the response to endoscopic dilatation in benign esophageal strictures. METHODS 27 patients with benign strictures (corrosive 14, peptic 10 & post-radiation 3) were prospectiv...

Ingested corrosive agents produce oropharyngeal and gastroesophageal injuries ranging from minor burns to severe necrosis, depending on the agent amount, concentration, and duration of exposure. The aim of this study was to present our patients with corrosive ingestion retrospectively. Four hundred seventy-three children younger than 16 years of age (mean age, 3.7+/-0.1 years) who were admitted...

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...

Серосодержащие высокотемпературные твердо-газовые среды, осложненные совместным присутствием кислорода и углерода, имеют существенное значение для процессов коррозионного разрушения различных конструкционных материалов. В работе выполнен анализ реакций взаимодействия серосодержащих составляющих анодной массы с материалом анодного штыря. Выявлены формы нахождения серы сернистых соединений в анод...

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 ...
