1. Skin corrosion refers to the production of irreversible damage to the skin manifested as visible necrosis through the epidermis and into the dermis, following the application of a test material [as defined by the United Nations (UN) Globally Harmonized System of Classification and Labelling of Chemicals (GHS)] (1). This Test Guideline provides an in vitro procedure allowing the identificatio...

Nd–Fe–B permanent magnets are characterised by excellent magnetic properties. However, being extremely vulnerable to the attack of both climate and corrosive environments, their applications are limited. This paper describes how, at different thicknesses of N-propyl-trimetoxy-silane, the coating affects the magnetic force of nickel plated magnets. We also investigate if the corrosion resistance...

In this paper, an experimental-theoretical method is suggested for defining physical-mechanical characteristics of polymer materials with regard to influence of corrosive liquid media. Experimental dependences of mechanical characteristics on a swelling function are given for a series of polymer materials. One dimensional and three-dimensional linear-elastic models of body deformation with rega...

The plastic hardener methyl ethyl ketone peroxide is unstable peroxide that releases free oxygen radicals. Ingestion of this compound induces widespread liver necrosis, severe metabolic acidosis, corrosive esophagitis and gastritis, that is often fatal. A 49-year-old man unintentionally ingested approximately 100 mL (55%) of this compound in solution, which was purchased as plastic hardener. De...

Methyl Ethyl Ketone Peroxide (MEKP) is a highly toxic clear liquid used as a solvent. It is a strong oxidizing agent and a corrosive. Acute and chronic toxicity can occur as an occupational hazard. Ingestion is associated with corrosive burns leading to stricture formation, inhalational pneumonitis, acidosis, liver failure and renal failure. In this paper we present a case of a young patient wh...

UNLABELLED Seven esophageal reconstructions with interposition colon in severe suicide corrosive ingestion and Boehave's injury at Thammasat University Hospital were presented. Vascular enhancement (as called "supercharge") were done. Only one patient had micro-leakage at pharyngeal anastomosis with healed by conservative treatment and no late anastomotic stricture. The operation need more time...

In this study microorganisms from Antarctic soils were isolated using different selective nutrient media. The soils were collected from different habitats of Livingston Island. The microorganisms were isolated and purified to pure culture. The isolated microorganisms were micro-morphologically and macromorphologically characterized. The results obtained suggested that despite the extreme Antarc...

Waters from natural sources of the São Miguel Island in the Azores archipelago have been investigated regarding their corrosive action on metallic materials. The corrosive and encrusting characteristics of the waters have been established in terms of relevant chemical parameters (namely pH, conductivity, total dissolved solids (TDS), and concentrations of bicarbonate, calcium, magnesium, chlori...

Ten cases of combined corrosive and peptic strictures of the oesophagus have been described. The peptic stricture of the oesophagus occurred 20 to 50 years after the corrosive burn. The authors believe that the hiatal hernia was due to the contraction of the fibrotic wall of the oesophagus, and therefore they prefer to call it a traction hiatal hernia. The operation of choice in these cases is ...
