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.
All welding for certification must be performed in the presence of testing lab personnel. The welder is responsible for all costs associated with testing required for certification. The certification remains in effect as long as the welder performs acceptable work for TxDOT as determined by the Bridge Division.
