Catamenial chest pain and spontaneous coronary artery dissection: A case report

Spontaneous coronary artery dissection (SCAD) is a rare cause of myocardial infarction, presenting mostly in healthy, young women. The pathogenesis is still poorly understood. A 45-year-old woman presented with an ST-elevation myocardial infarction, caused by SCAD of the mid left anterior descending coronary artery. In the six years prior to this event, she frequently experienced chest pain coinciding with her menstruation

Proposing supercritical fluids as a replacement for SF6 in high-voltage power switches: gas discharges in supercritical fluids for make and break operation

Gas discharges in supercritical fluids are an excellent candidate for high-power switching duty. Experimental and theoretical research has been performed. We present an analysis of results and a quick comparison with SF6 and CO2
