The mechanism of ATP synthesis discussed here assumes that protons extruded during electron transport are in the bulk phase surrounding the inner mitochondrial membrane (intermembrane and extramitochondrial spaces). An alternative view is that there are local proton circuits within or close to the respiratory chain and complex V, and that these protons may not be in free equilibrium with the bulk phase (Williams, 1978), although this has not been supported experimentally (for references see Nicholls and Ferguson, 1992). The chemiosmotic mechanism is both elegant and simple and explains all the known facts about ATP synthesis and its dependence on the structural integrity of the mitochondria, although the details may appear complex. This mechanism will now be discussed in more detail.

For an arbitrary choice of 8A, (27) becomes zero when (21) is satisfied. When (27) is zero, the magnetic energy is minimized and the helicity is held constant. Thus the state of minimum magnetic energy is a force-free equilibrium. 

The effect of diluents on the extraction of U02(TTA)2 B was studied10,83 87 and the adduct composition was reported to remain unaltered with change in diluent. However, the diluents have marked influence on the equilibrium constants as can be seen from the data given in Table 8. Attempts were made83 to determine diluent-free equilibrium constants by determining the activities of the solutes in different diluents. 

Figure A.4 (left), the equilibrium curve from the previous case becomes a surface of conical shape limited by the inert-free equilibrium curve and the edges AI and BI. It is to be noted that all the reactive residue curves start at the reactive azeotrope but with different paths towards the vertex I.

It has been known since the early studies of Kearney (192) that succinate dehydrogenase undergoes reversible activation by substrates, competitive inhibitors, and phosphate. The activation of succinate dehydrogenase was shown to be a characteristic of both the soluble and particle-bound enzyme and a slow process requiring many minutes of incubation with the activator at ambient or higher temperatures (activation energy = 31-33 kcal/mole). It has been suggested that the enzyme exists in a free equilibrium between the unactivated and the activated forms, and that the activator interacts with the latter and establishes a new equilibrium in favor of the activated state of the enzyme (23, 25, 193 see also 194 for an expanded mechanism). 

The calculated free equilibrium HDEHP dimer concentration using Equation 12 is illustrated in Table VI. The relationship of the equilibrated HDEHP dimer molar concentration with the total neodymium concentration and the total nitrate concentration in the organic phase is shown in Figures 5 and 6, respectively. 

The complexes with nickel(II), palladium(II), platinum(II), zinc(Il), cad-mium(II), mercury(II), and lead(II) and their adducts with nitrogen heterocycles have been described. The magnetic moment of the iron(III) complex is temperature-dependent owing to a spin-paired spin-free equilibrium. ...

The homogeneous assay is based on a competitive equilibrium between Ag and Ag for a limited amount of antibody as described (see Fig. 14 and Section 11.2). The assay relies on a decrease in the current signal for the reduction/oxidation of Ag when bound to Ab. Since all of these assays have no enzyme multiplication feature, the detection limits are generally much higher. In the model assay that follows, the free, equilibrium concentration of electroactively labeled estriol is determined by differential pulse polarography at a dropping mercury electrode (Wehmeyer et al., 1982). The peak current from the polarographic reduction of Ag is then proportional to the concentration of Ag present. The separation of Ab Ag from Ag is unnecessary because of the attenuation of the Ab Ag reduction. 

As chemical equilibrium problems are normally posed, we are given the total (analytical) concentrations of all components, the stoichiometry and stability constants of all species, and are asked to find the free equilibrium concentration of all components, from which we can easily compute the free concentrations of all species. This problem is solved as follows (see Tables I and II for description of symbols) from an initial guess for the concentration of components, the approximate concentration of the species can be computed ... 

Brown coals, like the hard coals, are also defined in terms of their calorific value (see the previous text) and were also recognized as potential fuels. The International System for the classification of brown coals is based on two inherent characteristics which indicate the value of brown coals as fuels (1) the total moisture (ash-free basis) and (2) the yield of tar (daf basis). Thus, the six classes of brown coal based on the ash-free, equilibrium moisture content are divided into groups according to the yield of tar on a dry, ash-free basis (Table 2.14). This system indicates... 

The finite field method works well as long as the field-dependent optimum structure corresponds to the same minimum as the field-free optimized structure. For the endohedral fullerenes considered in Ref. [60], especially for Li C6o, it appears that there were several minima lying nearby on the potential energy surface, which are separated by low energy barriers. As a consequence it was not possible to determine the NR contribution perpendicular the symmetry plane of the Cs symmetry structure using the finite field method. However, otxx" could be determined using alternative analytical formulae [24, 25, 27], which do not require field-optimized structures, but only dipole derivatives and the Hessian of the field-free equilibrium structure. 

Thermodynamics for engineering applications (TEA) It is based on the code of the thermodynamic library of ChemSep LITE, which is a free equilibrium column simulator for distillation columns and liquid-liquid extractors [16] and inclndes a data bank of over 430 commonly chemicals.
