Increased resistance to free radical damage induced by Conditioning is the phenomenon where exposure to moderate-level acoustic stimuli can increase the ear's resistance to subsequent more intense sound exposures. In recent years, research has shown that conditioning increases the availability of antioxidant enzymes

Low-level antibacterial resistance: a gateway to clinical The progressive enrichment in low-level resistant populations favours secondary selections for more specific and effective mechanisms of resistance, particularly in treated patients. These adaptations may have a biological cost in the absence of antibiotics, but frequently compensatory mutations occur, minimizing such genetic burden.
An Efficient Method to Reproduce the Effects of Acoustic -- &#; This complex valued quantity includes the resistance (R) that defines the in phase response of the fuel injector and the reactance (X) which is the out-of-phase response.The acoustic impedance can be found using experiment [,,] and this experimental data has been used to validate the ability of compressible CFD to predict
