WebApr 19, 2024 · An increase in P‐wave amplitude with faster HR suggests a cephalic shift on the CT where sinus nodal cells have a higher rate of automaticity. 4 While increased automaticity along the entire CT with preserved cephalic shift is a plausible hypothesis, our PR interval findings argue against it. Webdistance from earthquake * ( 1/ (S-wave speed) - 1 / (P-wave speed) ) ... The overall increase in seismic wave speed with depth into Earth produces an upward curvature to rays that pass through the mantle. A notable exception is caused by the decrease in velocity from the mantle to the core. This speed decrease bends waves backwards and creates ...

A P wave (primary wave or pressure wave) is one of the two main types of elastic body waves, called seismic waves in seismology. P waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph. P waves may be transmitted through gases, liquids, or solids. WebCompared to a dry soil, a soil with water generally has an increase in P-wave velocity and a decrease in S-wave velocity (Baechle et al., 2009; Kassab and Weller, 2015; Konstantaki et al., 2016 ...
