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.
RE: welding procedure for P1 to P4 material acc. asme IX. In my experience with the welding of boilers You can use metal filler for PROCESS GTAW SFA 5.18 and low hydrogen as per specification AWS 5.1 prefer E-7018-1 for Process SMAW.It is more Economic procedure and in accordance with CODE requirements.elding1 is correct. Qw-424.1 is very clear. If you have a WPS that has been qualified using P4 to P4 you can use the procedure to weld P4 to P4, P4 to P3, and P4 to P1 materials. I would write another WPS for the welding of P4 to P1 and support this WPS with the PQR for the P4 to P4 material.
