Per the "push-pulse theory of extinction"—a theory devised to explain the mass death of the dinosaurs any strain on an ecosystem leaves the species in it far more vulnerable to cataclysm.
Because there are long durations between pulses, theory predicts that few consumers will be specialists on such resources.
The focus here is on outlining some of these major developments, specifically in the context of paleontology, by emphasizing the significance of geographic isolation and allopatric speciation, punctuated equilibria, and the Turnover Pulse Hypothesis to evolutionary theory.
We applied Matsuda's pulse polarography theory to the study of electrode processes under non-Nernstian conditions and coupled to very fast chemical steps by differential pulse polarography (reaction layer approximation).
Another major innovation in macroevolutionary theory was Elisabeth Vrba's development of the Turnover Pulse Hypothesis (Vrba 1980 , 1985 1992).
The text describes the basic principles of magnetic resonance, steady-state and pulse methods, the theory of the width, shape and position of spectral absorption lines as well as the theory of relaxation times.
This problem is of larger importance than the fact that commercial GPR systems generate wide band radar pulses while RCS theory is frequency dependent.
