Nonetheless, the chevron plot shown in Fig, 9,12 exhibits a rollover, which means that the folding characteristic is not perfectly of two-state type, in which case the folding (unfolding) branches would be almost linear [217]. In this plot, the temperature dependence of the mean first passage time tmfp is presented. We define tmfp as the average number of MC steps necessary to form at least 13 native contacts in the folding simnlations,... [Pg.206]

In this variant of the chevron plot [217,220], the temperature T mimics the effect of the denaturant concentration that is in experimental studies the more generic external control parameter. The hypothetic intersection point of the folding and unfolding branches defines the transition state. The transition state temperature estimated from this analysis coincides very nicely with the folding temperature Tf 0.36 as identified in our earlier... [Pg.207]

In very recent work, the above variation was examined for three other surfactants, using pairs of core samples (Type I and Type II) that had been taken from the same well but differed from each other in permeability by factors of about 20. For each of the three surfactants, the mobility is shown on a log—log plot as a function of core permeability. The first of the four lines on each of the three plots are for surfactant-free brine—C02 mixture, and the others are for three different low concentrations. Figure 8 is for Chevron Chaser CD-1045, Figure 9 is for Henkel NES-25, and Figure 10 is for Chevron CD-1050. [Pg.223]

The presence of both acid and base catalysis terms in Equation 10.1 results in a characteristic chevron appearance of the plots of as a function of pH (Figure 10.1). [Pg.228]

Additionally, the acoustic emission technique was used during the test. Traces of cumulative number of acoustic emission (AE) events were obtained in the same time scale as the load vs. time plots. This technique allows for an accurate detection of the onset of microcracking at the chevron notch tip, which occurs when a sharp increase in the number of AE events is observed. Valid measurements for computing Kic were those in which this increase of AE events coincided with the end of the linear... [Pg.177]

For the PB and SCF methods, the precrack length is plotted. For the CNB method, the crack extension to maximum load is plotted. Figure 3a.

The curved solid line describes the frequency dependence of the threshold voltage for domains. The sloped dashed lines are the threshold plots for chevron formation. The material is MBBA at 25 C (Ref. [86]). Fig. 9—Various threshoid phenomena for nematic fiuids with negative dieiectric anisotropy and perpendicuiar alignment.
