Graphically Eq. (3-37) represents the logarithm of the differences between the experimental cb values at early times and the values extrapolated from late times. The plots of Eqs (3-36) and (3-37) should have the same intercepts and their slopes... 

The e.m.f. would thus be 0.048 volt, and its sign would be such that the spontaneous current transfers HC1 from ethanol to water. This is the sign that the resultant e.m.f. of equimolal cells, placed back to back, is found to have the value, extrapolated to infinite dilution, is either 0.296...

Ethylene chlorohydrin is highly irritating to mucous membranes but produces little reaction on contact with rabbit skin. Toxic amounts can be absorbed through the skin without causing dermal irritation the dermal LDso for rabbits is 68 mg/l. This value extrapolated to humans suggests that a volume slightly more than a teaspoon could be lethal with prolonged contact. ...

The wavelength thresholds are 338 nm for (31a) and 299 nm for (31b). Thus, (31a) is expected to predominate at the earth s surface. As might be expected, once excited, acetone can be collisionally quenched in competition with decomposition, and hence the quantum yields decrease with increasing total pressure. Figure 4.30, for example, shows the measured quantum yields for the decomposition of acetone at 760 Torr total pressure and the values extrapolated to zero pressure (Gierczak et al., 1998). In the tropospherically important wavelength region, the yields are small beyond about 330 nm at 1 atm pressure. 

The best way to use the Kozeny-Carman model and other permeability models (e.g. the anisotropic model by Gebart) [18], is to use them as interpolation formulas for intermediate volume fractions between known values. Extrapolation should be done with extreme caution because the models are developed for idealized reinforcements. Typical values for the permeability of different types of reinforcement are given in Table 12.1. 

Kaufman69 obtained the rate constant for the reaction 0 + C2H4 at room temperature. This is also in agreement with our value extrapolated to room temperature. 

Figure 17.3 Urea denaturation of bamase at 25°C. The open circles were measured directly at 25°C from the ratios [D]/[N], which were determined spectroscopically. The solid circles are values extrapolated to 25°C from thermal unfolding experiments at lower concentrations of urea and higher temperatures.

Quantum yields for adduct 63 and total product (63-65) formation from the reaction of - -t with several tertiary amines are summarized in Table 12. Quantum yields measured at 1.0 M amine concentration are lower than the values extrapolated to infinite amine concentration due to incomplete quenching of It. Extrapolated total quantum yields range from 0.07 to 0.33, providing a lower limit for the efficiency of the proton transfer step, kh> in Fig. 11. The other reaction products, 1,2-diphenylethane (64) and 1,2,3,4-tetraphenylbenzene (65), are formed mainly via in-cage radical pair disproportionation and out of cage combination, respectively. The relative importance of radical pair combination, disproportionation, and cage escape is dependent...

Table 4 summarises the trends found for the somewhat shorter period from 1993 to 2009, ranked in order of their annual values extrapolated back to 1990 using the trend analyses. Of the 29 stations analysed, the Mann-Kendall test [22] showed that 7 stations exhibited highly statistically significant (a < 0.1) downwards trends,...

Because it would be difficult to compare isothermal adsorption results for multiphase samples, the studies were restricted to NaY zeolite and the compound for which R = 0.05. For both solids, the logarithmic representations for the relation log N = f (log P), where N is the number of adsorbed xenon atoms per gram of dehydrated zeolite and P is the xenon equilibrium pressure, are straight lines. The line for the sample with R = 0.05 is below that of NaY zeolite (Figure 3). The log N value extrapolated to zero abscissa is smaller, and the slope is only a little larger. 

SLS studies were performed at four different copolymer concentrations c (0.33, 0.57, 0.75 and 0.85mg/mL). Because we learned from the kinetics studies that the sample equilibrium time was around 24 h, each solution was allowed to age for 24 h before data collection. Figure 9 shows the plot of Kc/Re as a function of q2, at those four concentrations and the values extrapolated to zero concentration (open circles).
