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...

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...

Background The disinfectants polyhexamethylene biguanide (PHMB) and 1-bromo-3-chloro-5,5-dimethylimidazolidine-2,4-dione (BCDMH) each have limitations. So far, their combined usage has not been examined. In this study, the fungicidal activity of combined disinfectant using PHMB and BCDMH, named PB, against Candida albicans was evaluated. Methods Suspension quantitative fungicidal test and via...

Accidentally ingested corrosive substances can cause functional and structural damage to the esophageal tissue resulting in stricture formation. It has been reported that the administration of olmesartan (OLM) can have anti-inflammatory, antifibrotic and antiapoptotic effects on injured tissue. The aim of our study was to check if OLM could prevent formation of scars in the corrosive esophageal...

Currently, the most promising approach in the corrosion protection of smart coatings is the use of nanoreservoirs loaded with corrosion inhibitors. Nanocontainers are filled with anti-corrosive agents and are embedded into a primer coating. Future prospective containers are halloysite nanotubes (HNTs) due to their low price, availability, durability, with high mechanical strength and biocompati...

In this series, six patients had periodic oesophageal dilatation with relief of symptoms. Two patients had feeding gastrostomies. Definitive surgical procedures were performed in 32 patients of which nine had oesophageal bypass, and 23 oesophageal resection with a visceral replacement. The colon was used in eight oesophageal bypass procedures and the jejunum in two. One patient who had a coloni...
