Condition Effects

Often it is not the rate kernel itself that is of interest, but rather the decay of the system from some initial nonequilibrium state. A case in point is the study of atom recombination following a photodissociation event. The initial state is presumed to correspond to a specific phase-space configuration of the pair of atomic radicals in an equilibrium solvent. The decay of this initial state is then monitored in the experiment. This is discussed in more detail in Section XII here we simply show how the kinetic theory can be formulated to accommodate this situation. 

We consider the pair formulation because it is most suitable for this application. The kinetic equation for the doublet distribution function 

We have suppressed the species labels. If there are only soft forces operating, yi2 P H dropped, and the potential in replaced by the 

An equation for P(l), the number of unreacted AB pairs at time /, can be constructed using the projection operator in (9.44), since 

This equation may be compared with (9.45), it differs because the term depending on the nonequilibrium initial condition for F(12) is present. In the large-volume limit we have

Unfortunately, excess consumption of fatty foods has been correlated with serious human disease conditions. Effects on cardiovascular disease (95), cancer (96), and function of the immune system (97) have been shown. Numerous studies have been conducted to determine the effects of saturated, monounsaturated, and polyunsaturated fatty acids on semm cholesterol and more recently high density Hpoprotein (HDL) and low density Hpoprotein... 

Pretreatment of Suspensions. Another important aspect of soHd—Hquid separation is conditioning or pretreatment of the feed suspension to alter some important property of the suspension and improve the performance of a separator that follows. A conditioning effect is obtained using several processes such as coagulation and docculation, addition of inert filter aids, crystalliza tion, freezing, temperature or pH adjustment, thermal treatment, and aging. The first two operations are considered in more detail due to their importance and wide use. 

One of the most interesting results of the zinc ferrite synthesis is the observation that the yield of the product is dependent on the early pressure history. This behavior is shown in Fig. 8.3, which plots the yield versus temperature for baratol explosive loading and for Composition B explosive loading. The difference between these loadings is that the initial pressure pulse amplitude is significantly greater with Composition B. Apparently, the early pressure history has an important conditioning effect for subsequent reactions.
