Gammarid acoustic emissions
Acoustic emission (AE) is the phenomenon of radiation of acoustic (elastic) waves in solids that occurs when a material undergoes irreversible changes in its internal structure, for example as a result of crack formation or plastic deformation due to aging, temperature gradients, or external mechanical forces. In particular, AE occurs during the processes of mechanical loading of materials and structures … WebGAMMAGARD LIQUID can cause the following serious reactions: Blood clots in the heart, brain, lungs or elsewhere in the body.
