We present new quantitative model describing the pressure dependence of acoustic P- and S-wave velocities. Assuming that a variety of individual mechanisms or defects (such as cracks. pore collapse and grain crushing) can contribute to the pressure-dependent change of the wave velocity. we order a characteristic pressure to all of them and allow a series of exponential terms in the de... https://parisnaturalfoodes.shop/product-category/super-immune/
