Desirable plant responses

This section qualitatively identifies indications the plant might use to identify abnormal or casualty events along with the desired plant response. Instrumentation that may be necessary for control or monitoring of plant parameters during these events is also identified. 

Indications, desired plant response and required instrumentation is thus the same as for Section 8.7.3.1, Bearing/Wheel Rub. 

For a two loop plant with one operating Brayton unit, the following would be the desired plant response. 

Further study of the possible interaction of pollutants would be desirable to help explain variations in plant response in different locations. 

We must recognize that plants, unlike animals, cannot move about. They are literally stuck with whatever environment they find themselves in. Natural selection over tens of millions of years has therefore resulted in the remarkable adaptability we see in plants today. Their ability to adjust to adverse environmental shifts, however, could also result in internal changes that either work indirectly to counteract a desired plant regulator effect or directly to correct for the elicited response. In either event, the plant regulator effect might then be shortlived. More sophisticated determinations of endogenous biochemical and... 

Veldstra (1944) had shown earlier that to induce growth response in a plant or plant tissue, the active molecule must meet three requirements (J) it must penetrate the tissues, (2) after penetration it must be able to move freely within the cell, so as to reach the site of action, and to accumulate there, without becoming inactivated by chemical or biochemical reactions or by being bound to the mssive parts of the cell, and (3) it must possess structural characteristics suitable to produce the desired growth response at the site of action. This activity has been called primary activity . 

The main problem with the use of conventional herbicides to produce a desired biological response in plants at a precise time is the use of a greater amount of... 

An attempt should be made to re-open the valve as soon as it no longer indicates fully open. If the affected valve can be successfully re-opened prior to loss of the Brayton unit, no further immediate actions may be required. If the valve cannot re-opened, then the following plant response would be desired regardless of whether one or two Brayton units were initially operating. 

Complex manufacturing systems, such as an unbleached Kraft pulp plant (Fig. 9), are almost always characterized by some type of internal structure, composed of a number of interconnected subsystems with their own data collection and decisionmaking responsibilities. This raises a number of additional issues, not addressed in previous sections. For instance, if the learning methodology described in Section VI is applied to the digester module of a pulp plant (Fig. 9), it is possible for the final selected solution, to include ranges of desired values of sulfidity... 

An internal standard method gives more reliable results when elaborate sample preparation is required, as in extraction of a drug substance from biological fluids, or extraction of pesticides and herbicides from soil and plant matter. The addition of internal standard (IS) to the sample and standard acts as a marker to give accurate values of the recovery of the desired compound(s). Since the determination of wt% involves the ratio of the detector responses in the two chromatograms, the injection volume is not critical as in an external standard method.
