COM includes a model for compound documents called OLE (a collection of standard COM interfaces) and includes ActiveX controls, another set of COM interface standards that include outgoing interfaces to permit events to be signaled by a control to its container. ActiveX controls also have properties that are similar to JavaBeans properties.

Response Surface Methodology (RSM) was used to investigate the effects of temperature, pH and relative concentration on the quantity of selected volatiles produced from rhamnose and proline. These quantities were expressed as descriptive mathematical models, computed via regression analysis, in the form of the reaction condition variables. The prevalence and importance of variable interaction terms to the computed models was assessed. Interaction terms were not important for models of compounds such as 2,5-dimethyl-4-hydroxy-3(2H)-furanone which are formed and degraded through simple mechanistic pathways. The explaining power of mathematical models for compounds formed by more complex routes such as 2,3-dihydro-(lH)-pyrrolizines suffered when variable interaction terms were not included.

Multiple-species risk for independent combined effects in terms of the potentially affected fraction of species can be assessed using models that are essentially the same as for the prediction of response-additive effects in single species. The underlying assumption in the application of a response addition model for compounds or groups of compounds with different modes of action is that correlation of species sensitivities to the different constituents of the mixture is again considered absent. The calculation...

FIGURE 3.6 Compartmental analysis for different terms of volume of distribution. (Adapted from Kwon, Y., Handbook of Essential Pharmacokinetics, Pharmacodynamics and Drug Metabolism for Industrial Scientists, Kluwer Academic/Plenum Publishers, New York, 2001. With permission.) (a) Schematic diagram of two-compartment model for compound disposition. Compound is administrated and eliminated from central compartment (compartment 1) and distributes between central compartment and peripheral compartment (compartment 2). Vj and V2 are the apparent volumes of the central and peripheral compartments, respectively. kI0 is the elimination rate constant, and k12 and k21 are the intercompartmental distribution rate constants, (b) Concentration versus time profiles of plasma (—) and peripheral tissue (—) for two-compartmental disposition after IV bolus injection. C0 is the extrapolated concentration at time zero, used for estimation of V, The time of distributional equilibrium is fss. Ydss is a volume distribution value at fss only. Vj, is the volume of distribution value at and after postdistribution equilibrium, which is influenced by relative rates of distribution and elimination, (c) Time-dependent volume of distribution for the corresponding two-compart-mental disposition. Vt is the starting distribution space and has the smallest value. Volume of distribution increases to Vdss at t,s. Volume of distribution further increases with time to Vp at and after postdistribution equilibrium. Vp is influenced by relative rates of distribution and elimination and is not a pure term for volume of distribution. 

Dalton used different labeled spheres and, even if they were not always correct, came up with first models for compounds (see Fig. 1.3). He assumed, for instance, that the water molecule should be described by one H atom combined with one O atom, thinking of today s symbol HO (see Fig. 1.3, Number 21). 

Iron(III) porphyrins with imidazole anion(s) as ligands have been synthesized in non-aqueous media"" , and are potential models for heme-containing enzymatic species. Metalloporphyrin vr-cation radicals generated electrochemically (but never from iron porphyrins) are models for compound I or horseradish peroxidase " (see 14.8.5.3.2).

Theoretically, a linear correlation between S and log kw is expected for any system where a single solute interaction dominates retention. Members of a homologous series, for example, have similar polarity and differ only in size and should conform to the linear model. For compounds that differ significantly in the type and capacity for polar interactions only poor correlations are generally observed.
