First, the pH-dependence of the enantioselectivity of the reaction between 3.8c and 3.9 catalysed by the copper(L-tryptophan) complex has been studied. Above pH 5 the enantioselectivity reaches a plateau value (Figure 3.3). The diminished enantioselectivities observed at lower pH most likely... 

As the frequency of blinking increases, the range between [M-]min will narrow, approaching a plateau value below [M ] ... 

Figure 1. Relative change of resislivily during isochronal annealing (AT=10K, At=10min) of completely recrystallized CujAu Tlie LRO-parameter as calculated by Rossiter formalism (A=0 5) is given on second axis ( ) increasing, (0) decreasing temperature (o) plateau values of small step annealing procedure.

In Figure 1 in addition to isochronal measurements plateau values of a small step armealing treatment (order-order relaxations) are given for a comparison (o). These points reflect a variation of equilibrium state of LRO-parameter with temperature. 

Additional isothermal treatments at neighbouring temperatures small step annealing) yield plateau values of resistivity corresponding to equilibrium values at certain temperatures which reflect the order parameter in thermal equilibrium as a function of temperature ( equilibrium curve , curve 4 in Figure 1). This study can be used for an analysis of the kinetics of order-order relaxations (see Figure 3 below).

Note the different timescales of t2 at the different temperatures. The straight lines indicate the decays of the plateau values on the timescale of the spin-lattice relaxation time T,.

As shown by the dashed curves in Figure 30.16, fitting 1.0 Hz results with Equation 30.4 yields plateau values, which likely have no physical meaning, with respect to 0.5 Hz data. However, fit parameters of this equation (as given in Table 30.2) allow the slope to be calculated at any strain within the experimental window. It follows that the slope at a given strain, for instance 200%,... 

Figure 1 shows the methyl ester yield as a function of the reaction time for the transesterification of cottonseed oil catalyzed by the solid bases and acids. Of the solid bases, CaO and Mg0-Al203 were more effective for this reaction. Over 90% methyl ester was obtained in less than 3 hours. The reactions catalyzed by the solid acids were slower than that by the solid bases, which need about 9 hours to reach high concentration of ME. The different plateau values of the solid bases may be caused by the deactivited of the catalysts. 

The plateau values of G have been plotted as a function of pectin concentration as expected, the gel elasticity increased with the amount of pectin... 

Several scouting experiments were performed to find the best pH conditions. Figure 3 reports the ratio between the PG specific activity measured after the purification procedure (ASf) and the initial PG specific activity (ASi). At pH 3.5, the microspheres are able to remove from the broth the major part of the protein without PG activity, thus providing a four time increase of the enzyme specific activity. The purified PG from Kluyveromyces marxianus was immobilised following the above procedure. Batch reactions in the packed bed reactor were done to evaluate the biocatalyst stability. After an initial loss, due to enzyme release, the residual PG activity reaches a plateau value corresponding to about 40% of the initial activity. Probably, some broth component interfered during the immobilisation reaction weakening the protein-carrier interactions. 

When the load has reached a critical plateau value, the crack continues to propagate at constant load. Crack propagation can be stopped by removing the load, with the implication that several readings can be made on one test specimen. Crack velocity is determined by the crosshead speed, modulus of the material and specimen dimensions. 

From this expression we see that the friction cannot be determined from the infinite-time integral of the unprojected force correlation function but only from its plateau value if there is time scale separation between the force and momentum correlation functions decay times. The friction may also be estimated from the extrapolation of the long-time decay of the force autocorrelation function to t = 0, or from the decay rates of the momentum or force autocorrelation functions using the above formulas.
