Jugular venous monitoring (necessary during chemically induced coma only). The problem with increased ICP is that the fluid under pressure tends to deform the brain itself and pushes tissue in such a way as to cause injury to the brain itself. A MRI or CT taken at the emergency room or during follow-up care, can often show the shifting of the tissue because of the pressure.
Electron beam welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact.
View Full Version : Auto darkening helmet and burning eyes questions PLEASE!!! I have two el-cheapo welding helmets. The first is a Harbor Frieght (HF) model and the second is a Northern Tool (NT) model. With the exception of the blue flame stickers, vs. Orange flame stickers, they are identical in ALMOST every way. I'm assuming they are Chinese JUNK...... Anyway, after a half day of welding, my eyes feel like they are burning ever so slightly no matter which of the two helmets I use. I must preface that Im not a professional and I'm just an occassional amatuer lawn-art weekend welder..
