The article considers the processes of corrosion vehicle body influenced by road pollution components. It is noted that support frameworks, especially their bottom, are most susceptible to damage. This due presence in such bodies seams, gaps, as well hollow elements (spars, amplifiers, thresholds), which create favorable conditions for occurrence and development processes. A decisive role this ...

The effect of an inert solid deposit on uniform CO2 corrosion of mild steel is modeled based on a mechanistic electrochemical CO2 corrosion model. Laboratory testing has shown that the dominant factors introduced by the inert solids deposit are related to surface coverage, where both anodic and cathodic reaction rates are decreased because of less active surface area being exposed. The inert so...

The collapse of the Soviet Bloc caused devastating economic crises in Cuba and in the Russian Federation but triggered remarkably different public health responses: while mortality rates in Russia increased substantially the crisis was barely visible in Cuban public health statistics. Fundamental social, political and cultural differences in the two countries and the respective specificities of...

background: sodium hypochlorite is found in bleaching agents used to cleaning dishes and bleach laundry. the ingestion of sodium hypochlorite causes acute corrosive esophagitis and gastritis. in establishing the diagnosis and therapeutic approach of acute corrosive poisonings, the upper endoscopy has great importance. the aim of this study was to determine predictive factors of gastrointestinal...

background: ingestion of caustic agents can cause serious damages of the upper gastrointestinal tract and in some cases this kind of poisoning may have fatal outcomes. acute caustic intoxications are one of the main problems in the modern clinical toxicology since they mainly affect young people with psychic disorders, suicidal intent, and alcohol addiction. text: in diagnostic evaluation of th...

The lack of suitable materials solutions stands as a major challenge for the development of advanced nuclear systems. Most issues are related to the simultaneous action of high temperatures, corrosive environments and radiation damage. Oxide nanoceramics are a promising class of materials which may benefit from the radiation tolerance of nanomaterials and the chemical compatibility of ceramics ...

BACKGROUND Esophageal stricture (ES) and gastric outlet obstruction (GOO) can occurred in patients injured by the ingestion of corrosive agents. These complications may occur concurrently but has not been reported in the literature. The aims of this study are to assess the effects and complications of endoscopic-guided balloon dilations (EBD) in patients with corrosive-induced upper gastrointes...

The corrosion fatigue crack growth characteristics of small (>35pm) surface and corner cracks in aluminum alloy 7075 is established. The early stage of crack growth is studied by performing in situ long focal length microscope (500X) crack length measurements in laboratory air and 1% NaCl environments. To quantify the “small crack effect” in the corrosive environment, the corrosion fatigue crac...
