As we intend to apply discontinuous automatic analysis as a sensor in process regulation, we must now first consider the manufacturing process as a "black box also, and next discuss how the analytical sensor functions. 

A more complicated situation in process regulation occurs when among various chemical properties there is not one that can explicitly be indicated as a key test, so that more than one sensor (1,2,..., n) has to be used, in which case one refers to "multivariable systems in process control 6. 

Among the various advantages of electroanalysis in general, as mentioned in the general introduction (p. XV), we can stress again, considering automation, the direct accessibility to electronic and hence automatic control even at a distance, simple automatic data treatment and simple insertation, if desired, into a process regulation loop.

Mutations in either recA or lexA can abolish the SOS-response and eliminate both W-reactivation and W-mutagenesis. These mutations also eliminate the mutability of the bacteria by UV-irradiation (16) The observation that UV mutagenesis depended on the SOS-response established that mutations were not inevitable outcomes of DNA damage and that DNA damage required processing by cellular mechanisms in order for mutations to be recovered. What specific processes regulated by the SOS-response are responsible for mutagenesis ... 

Over the last four decades, cAMP has been shown to serve as an intracellular second messenger for numerous extracellular signals in the nervous system. In fact, the number of functional processes regulated by cAMP is too large to enumerate here in detail. It is important, however, to review the general types of effects that cAMP exerts in neurons.

Indicators of microbial activity in soil represent measurements at the ecosystem level (e.g., processes regulating decomposition of organic residues and nutrient cycling, especially nitrogen, sulfur and phosphorus). Measurements at the community level include bacterial DNA and protein synthesis. Frequency of bacteriophages is a measurement at the population level.

Around one third of all new registrations is for intermediates and process regulators (for synthesis processes), and are thns rather part of a (synthesis) process innovation. 

It is clear, as shown in Figure 10.9, that the choice between the two pathways is the result of a competition between the velocities of the two processes, regulated hy the relative rate of binding, and assembly formation, respectively. If the rate of vesicle formation is per se very high, there is no possibility for binding and for the eventual growth and reproduction of the old vesicles.
