Principle of maximization

In addition, as a rule, the principle of maximal connectivity holds for elements of the third and higher periods the 8 — N bonds usually are bonds to 8 - IV different atoms, and multiple bonds are avoided. For carbon, however, being an element of the second period, the less connected graphite is more stable than diamond at normal conditions. At higher pressures the importance of the principle of maximal connectivity increases then, diamond becomes more stable. 

Suppose Eq. (6) has a solution with the given asymptotic conditions, which holds true in a wide range of cases [2] then one associates to a given/( ) a solution of the steady state of the Vlasov-Newton equation. There are various restrictions on possible functions/( ) It must be positive or zero and such that the total mass is finite. Of course, as we said, this is not enough to tell what function f E) is to be chosen. Moreover, knowing l>(r), it is possible in principle to find the function/(E) from Eq. (6) by writing the left-hand side as a function of <1) (instead of r). Then there remains to invert an Abel transform to get back/(E). We shall comment now on the impossibility of applying the usual methods of equilibrium statistical mechanics to the present problem (that is, the determination of f E) from a principle of maximization of entropy for instance). 

Where intermediates do accumulate, it is often through the use of synthetic, highly reactive substrates, such as esters with chymotrypsin, or through the effects of pH with alkaline phosphatase. There is a good theoretical explanation. It is a corollary of the principle of maximization of rate by the mutual increasing of kcat and Km that the accumulation of intermediates lowers the reaction rate.4 Any intermediate that does accumulate lowers the KM for the reaction, causing saturation at lower substrate concentrations. In other words, the accumulation of an intermediate means that the reaction has fallen into a thermodynamic pit. ... 

Vapor Generation Vapor generation systems are based on the principle of maximizing the surface area of the liquid, and the temperature (within the limits of chemical stability) and airflow across the surface of the liquid as a means of increasing efficiency. 

We follow the procedure introduced by Hartikainen and Mikkola (1997) of using the principle of maximal rate of entropy production (Ziegler and Wehrli, 1988) with the orthogonality relations...

The WSA method comes from principle of maximization of benefit. Simplification of this method is that it is assumed only linear function of benefit. Benefit of variant is following (Formula 3) ... 

The TOPSIS method is based on the principle of maximization of distance from ideal variant. The initial step is construction of criteria normalised matrix R = (r,y). For this normalization is proposed following formula (9) ... 

In essence a similar rationale underlies the Murrell-Laidler theorem on the structure of potential energy surfaces near transition states [74,75]. The assertion that a chemical transition state should always be a saddle point between only two valleys - a reactant valley and a product valley - indeed is based on the assumption that the potential near the transition state is dominated by second-order interactions. Further interesting analogies can be drawn with the maxinudity principle for phase transitions in the solid state [14], the principle of least motion [9] in chemical reaction theory and the related principle of maximal symmetry expressed by Rodger and ScMpper [76]. 

There are also many situations where demetallation of coordination compoimds obtained by template pathways is impossible. The reason for this is the high thermodynamic and kinetic stability of these metal complexes according to the principle of maximal correspondence between the cavity and the metal ion (PMCCMI). This principle requires a number of conditions [32] to be fulfilled ...

This expression differ from the Shannon entropy in two basic aspects first, it has the multiplying Boltzmann factor, a signature of thermodynamic phenomena, and second, the logarithm is taken in the natural basis. The probability pk is the occupation number for the energy level Ek, or its population. At thermal equilibrium at temperature T, the probabilities can be obtained from the principle of maximization of the entropy [12] ... 

It is important that the principle of maximal simplification of the target molecule cannot be exactly defined or even quantified. Usefulness and easy understanding characterize this principle, like most rules in chemistry. 

Two plausible disconnections are presented in Scheme 2.24 (a) disconnection of the C-C bond between the a-C atom and carbonyl C atom and (b) disconnection of the C-C bond between the a- and 3-C atoms to the carbonyl group. Both disconnections follow the principle of maximal simplification of the target molecule. 

It is surprising that the contradicting principle of maximal simplification disconnection b competes with disconnection a (Scheme 4.17). The carbanion of...
