Long-time process

Impulse for the valuation of the chamomile collection has become if the identification of four chemical types of this plant species different by the qualitative -quantitative composition of chemical compounds in the essential oil was carried out by Schilcher in 1987 (Table 7.6). This veiy important fact was referred to chamomile biodiversity. This biodiversity was created during long time process (evolution) inregardtoinfluenceofeco-physiological conditions (biotic-andabiotic-factors) on the concrete place of chamomile population growth. 

Figure 3-7 Plot of nominal space times (or reactor residence times) required for several important industrial reactors versus the nominal reactor temperatiwes. Times go from days (for fermentation) down to milliseconds (for ammonia oxidation to form nihic acid). The low-temperature, long-time processes involve liquids, while the high-temperature, short-time processes involve gases, usually at high pressures.

What makes the neutral final state or complete screening condition approximate rather than exact is the time required for the system to respond to the core excitation (the various time scales are discussed by Gadzuk (1978)). In this work we are concerned only with the excitation energy, the threshold for absorption. Since the threshold corresponds to a long-time process (in the sense of a Fourier transform of a correlation function), the actual dynamics of complete screening will have negligible effect on the threshold energy but will affect the lineshape. 

The existence of equations 21 and 22 raises the question as to why one should bother to deal with both spectra since they are interrelated and they present in principle the same information. But the viscoelastic behavior is seen differently in the two, since H weights contributions to modulus and L contributions to compliance. Generally, short-time processes are revealed in more detail in H, and long-time processes in L. Accordingly, it is worthwhile to examine both spectra.
