Region decreasing

Similar curves determined in 50 Vo sodium hydroxide solution at 60°C show (Fig. 3.46) that the austenitic irons exhibit more noble active dissolution and also lower current densities in the active and passive regions than the ferritic irons the current densities in both regions decrease markedly with increasing nickel content (Fig. 3.47). 

By small-angle neutron scattering experiments on water/AOT/hydrocarbon microemulsions containing various additives, the change of the radius of the miceUar core with the addition of small quantities of additives has been investigated. The results are consistent with a model in which amphiphilic molecules such as benzyl alcohol and octanol are preferentially adsorbed into the water/surfactant interfacial region, decreasing the micellar radius, whereas toluene remains predominantly in the bulk hydrocarbon phase. The effect of n-alcohols on the stability of microemulsions has also been reported [119],...

Figure 6.4 also illustrates a mechanism whereby 13C may be introduced into the inter-shell convection zone of a low- or intermediate-mass star. When that zone reaches its maximum extension, it covers almost the whole inter-shell region apart from a thin interval marked A. The mass of this region decreases from about...

A The largest real part of the eigenvalues as a function of the feedback strength 0 TP, depicted for increasing saturation of the overall ATPase reaction. B The metabolic state is stable only for an intermediate value of the feedback parameter. For increasing saturation of the ATPase reaction, the stable region decreases.

The emissions were greatly influenced by the primary zone equivalence ratios. The residence times at the high-temperature region decreased with decreased fuel-air ratio, resulting in a drastic increase in CO and UHC emissions. CO and UHC emissions also increased for very lean mixtures because of lower combustion temperatures. For the baseline cases NOj, emissions were found to increase with increased fuel-air ratio whereas, with porous inserts installed, varying fuel-air ratio generally had little influence on the NOj, concentrations. 

If the catalyst acts in the fizz zone or in the dark zone, becomes smaller than r f n or respectively. As shown in Fig. 8.24, the behavior of qy corresponds to that of r y. Both catalyst activities have positive values in the super-rate region, decrease with increasing pressure in the plateau region, and finally both become negative above 3 MPa. This indicates that the catalyst acts as a positive catalyst in... 

The state of stability under these conditions can be qualitatively described as follows. As two oil droplets approach each other, the negative charge gives rise to a repulsive effect (Figure 7.4). The repulsion will take place within the electrical double-layer (EDL) region. It can thus be seen that the magnitude of double-layer distance will decrease if the concentration of ions in the water phase increases. This is because the electrical double layer region decreases. However, in all such cases in which two bodies come closer, there exists two different kinds of forces that must be considered ... 

Fe(III) refers to the sum of all three-valent iron in solution, i.e., Fe(III) = Fe3++ FeOH2+ + Fe(OH)2+ + FeOHSO-, + FeSO + etc. Thus the rate of the iron-catalyzed reaction in the low-pH region decreases with increasing [H + ], This means that it shows the behavior depicted in Fig. 8.9a i.e., it is self-quenching. That is, as S(IV) is oxidized to the acid, the pH falls and the rate also decreases.
