moisture and air pollutions intensify metallic and nonmetallic surface corrosions. corroded surfaces exposed to rain washing cause pollution transportation in water and soil environment, especially in industrial areas. investigation of storm runoff quality in pars special economic energy zone (pseez) has shown heavy metals in storm basins of gas refineries and petrochemical industries.in this p...

OBJECTIVE We retrospectively evaluated the effectiveness of the esophageal balloon dilatation (EBD) in children with a corrosive esophageal stricture. MATERIALS AND METHODS The study subjects included 14 patients (M:F = 8:6, age range: 17-85 months) who underwent an EBD due to a corrosive esophageal stricture. The causative agents for the condition were glacial acetic acid (n = 9) and lye (n ...

Effects of nanoparticles (NPs) on skin corrosion and irritation using three-dimensional human skin models were investigated based on the test guidelines of Organization for Economic Co-operation and Development (OECD TG431 and TG439). EpiDermTM skin was incubated with NPs including those harboring iron (FeNPs), aluminum oxide (AlNPs), titanium oxide (TNPs), and silver (AgNPs) for a defined time...

certain gases, principally oxygen,o , and carbon dioxide, co , dissolved in water accelerate its corrosive properties. the rate of corrosion is approximately in prportion to the quantity of gas dissolved. the removal of gases from water, as practiced in steam station, is effected by mechanical and thermal treatment , by addition of chemicals, or by combinations of these processes, the most wide...

Five patients are described who had retrosternal pains following the consumption of CetiprinR tablets. The pains increased so markedly within a few days that, initially, solid foods and, subsequently liquid foods also were impossible to swallow. Typically the history was of the comsumption of a tablet in the evening or night without fluids and the pains lasted 2--3 weeks. A marked corrosive inj...

Existing theories describe corrosive wear in crosshead diesel engines in terms of acid condensation, when the temperature in the combustion space drops below the dew point. Here a theory is proposed which stresses the role of alkaline cylinder lubricants in protecting the metal surface. Calculated liner wear rates as a function of fuel sulphur content, feed rate and alkalinity of the oil, and a...

Introduction Esophagogastroduodenoscopy (EGD) is currently considered as the primary method of determining the degree of mucosal injury following caustic ingestion. The present study aimed to evaluate the screening performance characteristics of EGD in predicting the depth of gastrointestinal mucosal injuries following caustic ingestion. Methods Adult patients who were referred to emergency d...

Suicides are divided into simple and complex, the complex one referring to suicide by a combination of more than one method. In general, unplanned complex suicides occur where several different methods are used consecutively because the first method has not achieved the desired effect. In this study, we present a unique unplanned complex suicide case where corrosive ingestion and stabbing were ...

OBJECTIVE The authors reported the feasibility and safety of thoracoscopic approach for resection of the esophagus in two patients with diffuse corrosive esophageal stricture. BACKGROUND The unrelenting corrosive strictures of esophagus merit esophageal substitution. Because of the risk of complications in the retained esophagus, such as malignancy, mucocele, gastroesophageal reflux, and blee...
