Doctor suggested cortisone injection and on July 13 I had a shot in my shoulder. The pain lessened. I had been doing physiotherapy for 9 weeks before and after the shot. However I was at work and had to hop up over a small counter top. My life has been a severe painful nightmare since then. The pain I've been experiencing since that day is unbearable. I was not told that cortisone weakens the tendons in and around the area of the injection. The doctor gives me strong pain killers but they have side effects that I'm looking forward to.
An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
A ring in the mathematical sense is a set together with two binary operators and (commonly interpreted as addition and multiplication, respectively) satisfying the following conditions: 1. Additive associativity: For all, , 2.Additive commutativity: For all, , 3.he word ring is short for the German word 'Zahlring' (number ring). The French word for a ring is anneau, and the modern German word is Ring, both meaning (not so surprisingly) ring.. Fraenkel (1914) gave the first abstract definition of the ring, although this work did not have much impact.
