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.
For example, a job description may require a welder certified at the level of 4-G. The G stands for groove welding. The number indicates the position of the welder in relation to the work.If you examine the welds below, you can see four different positions, starting with the easiest.ust below that is a 5G cert, which involves pipe welding in the vertical position. The video above describes a typical qualification test used in welding certification. Please note that the welder's part of this test starts when you see the number 2 in the lefthand corner of the screen. The test stops after Step 8.
