A system for the regeneratlon of caustic soda solutlons used In etching aluminum Invokes the hydrolysis of sodium aluminate to llberate free sodium hydroxide and produce a dry, crystalllne hydrated alumlna byproduct. The system has been used extenslvely In Japan, and, by adjusting process parameters, can be adapted to North American practice. By otlllting the system in a typical plant, soild ai...

From AOSE Methodologies to MAS Infrastructures: The SODA Case Study

Research on agent-oriented software engineering (AOSE) methodologies and multi-agent system (MAS) infrastructures has developed in the last years along two opposite paths: while AOSE methodologies have essentially undergone a top-down evolution pushed by contributions from heterogeneous fields like human sciences, MAS infrastructures have mostly followed a bottom-up path growing from existing a...

An acute fatality from suicidal caustic soda ingestion complicated by stab wound penetrating the stomach.

Acute death from caustic ingestion is uncommon. We report an autopsy case of acute fatality from suicidal ingestion of a liquid caustic soda solution with peritoneal leakage due to a stab wound to the stomach. The victim was a 58-year-old man, who died about 1 h after being transported to a hospital emergency care unit. There were corrosive erosions around the mouth and a stab wound in the lowe...
