Pulse rate, acceleration

J.H. (a 24-year-old male) ingested four cooked mushrooms at night, after a meal ( ), and then ate another three fresh mushrooms 30 minutes later. This was followed by regurgitation, and 45 minutes later, he started to sweat profusely all over his head and body. His pulse rate and breathing were accelerated, but slowed down later on. He laid down and experienced visual... 

In TOF-SIMS, the source of primary ions is pulsed at a rate of a few kHz. The pulse width is on the order of 1 ns. Secondary ions ejected from the sample surface are accelerated through a potential V and then drift through a field-free TOF analyzer with different velocities, depending on their masses. The drift velocity of an ion with charge-to-mass ratio zjm can be determined from the expression ... 

The ramp of pressure to about 3 GPa observed in shock-loaded fused quartz has been used very effectively in acceleration-pulse loading studies of viscoelastic responses of polymers by Schuler and co-workers. The loading rates obtained at various thicknesses of fused quartz have been accurately characterized and data are summarized in Fig. 3.6. At higher peak pressures there are no precise standard materials to produce ramp loadings, but materials such as the ceramic pyroceram have been effectively employed. (See the description of the piezoelectric polymer in Chap. 5.)...
