This twists the O-ring as the sealed device is cycled and finally causes a series of deep spiral cuts (typically at a 45-degree angle) on the surface of the seal. Explosive decompression – An O-ring embolism, also called gas expansion rupture, occurs when high pressure gas becomes trapped inside the elastomeric seal element.
Moderately severe scoliosis (30–45 degrees) in a child who is still growing requires bracing. A 2013 study by Weinstein et al. [ 9 ] found that rigid bracing significantly reduces worsening of curves in the 20-45 degree range and found that 58% of children receiving "observation only" progressed to surgical range.
EDC injection inline pump. The mechanical fly-weight governors of inline and distributor diesel fuel injection pumps used to control fuel delivery in diesel engines under a variety of engine loads and conditions could no longer deal with the ever-increasing demands for efficiency, emission control, power and fuel consumption. These demands are ...
