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...

Corrosive Sulfur in transformer oil has been the cause of high profile transformer failures in recent years. Oil treatments consisting of copper passivators have been only partially effective. DSI has discovered a multi-step method that has been proven to change oils with corrosive sulfur into non-corrosive status, as well as significantly slowing oxidation and ageing of insulating oil and pape...

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...

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 ...

Niobium based super alloys are an unusual class of metallic materials with an exceptional combination of high temperature strength, toughness, and resistance to degradation in corrosive or oxidizing environments. The focus of present work was to study the effect of cutting parameters – speed, feed and depth of cut on the machinability of Niobium C-103 under dry machining condition using respons...
