Behaviour modification process involvement

The Michaelis - Menten relation is also obeyed in the processes involving the immobilized ADH (K =44.2 mM). The diffusion effect does not explain in a satisfactory way the increase of Kj, so that conformational modifications of the active center must be considered to affect the enzyme kinetic behaviour. It is known that the ADH molecule consists of 4 protomers bound through a Zn atom to 4 molecules of coenzyme In the coupling processes the carrier - enzyme chemical bond is formed at one protomer only, and the quaternary structure is destroyed. In fact, at lower coupling pH values (pH=8) the ADH activity is strongly diminished probably due to the structure splitting in non-bound protomers, the ADH being active as a complete structural composition only. 

Early laboratory and field study work carried out by Adam and Scott (1971), Adam (1975), McCarthy (1978) and Kim and Hammer (1976) had already demonstrated the potential of behaviour modification techniques in a quality improvement process. These studies, however, tended to focus on specific, time-bound experiments within a particular setting or occupation. We were much more interested in applying a behaviour-based approach within a plant operating a continuous production process, involving several departments, and consisting of multiple skills and skill levels. So, it seemed to us that quality behaviour, unlike safety behaviour, would be contingent on interactions with other people and we would need to optimize... 

The design and optimisation of chemical processes involves the study of both steady state and dynamic behaviour. Steady state and dynamic simulation modes help in the process development by analysing and validating the design and/or ideas before their implementations to avoid costly modifications and to ensure safe operations. 

Many drugs can be obtained in different polymorphic modifications. These forms may possess fundamentally different properties, for instance different rates of assimilation because of differences in solubility [12]. The enormous economic implications of this aspect are witnessed, interalia, by the number of patent litigations involving drug companies. Polymorphs may also show different behaviour under mechanical stress, with relevant consequences on comminution and tableting, hence on their processing and marketing [13].
