King s experiments, described above, showed a complicating feature which makes it difficult to determine the borderline between gravitational and capillary moisture. After the columns drained for two and one-half years, King determined the moisture-content of each column at 3 in. sections. These results are shown in Table 54. The table illus-... 

We often see splitting patterns in which the intensities of the individual peaks do not match those given in Table 13 2 but are distorted in that the signals for coupled protons lean toward each other This leaning is a general phenomenon but is most easily illus trated for the case of two nonequivalent vicinal protons as shown m Figure 13 18...

Once a fitted model is refined to the point where the corresponding figure of merit is smaller than the benchmark (Table 1.26), introducing further parameters or higher dimensions is (usually) a waste of time and only nourishes the illusion of having enhanced precision. 

Observation 1 is an illusion due to the fact that the above numbers measure the overall spread in one dimension (vertical or horizontal), and do not take into account the correlation between the results A and B that is very much in evidence in the right side of Fig. 4.22 (automatic injection), also see Fig. 1.23. The variability can be measured in five different ways (see Table 4.20) ... 

These values, drawn from various sources, are presented solely for illus-tration. The table should not itself be used uncritically as a source of a values for correlations. See rather References 13, 17 and 18. The values for CO2H will be discussed later in this chapter. 

The most dramatic illustration of a mass-specific illusion is the comparative heat dissipation of the human erythrocyte and platelet. In mammals, both of these cell types are anucleate and discoid in shape, but the longest dimension of the former is four times that of the latter. Yet heat production of a human erythrocyte was shown to be 10 fW, a sixth that of a human platelet (61 fW see Table 1). The relatively high metabolic activity of platelets is probably due to the need to maintain a considerable phosphagen (phosphocreatine) pool for actomyosin contraction at stimulation and clot retraction. Phosphocreatine is synthesized from creatine using ATP and acts as a demand on the ATP cycle to drive the coupled catabolic half-cycle. On the other hand, ATP requirements of the erythrocyte are relatively small, being mostly confined to active transport of ions at the plasma membrane. 

To illustrate this, consider a watercourse that exceeds a threshold 1% of the time. Such a watercourse will always be reported as a failure of the absolute limit if assessed using continuous, error-free monitoring. Table 3.2 shows that if assessed by sampling, this failure will escape detection with a probability that depends strongly on the number of samples.2 With 4 samples, there is 4% probability that at least 1 exceeds the absolute limit. This rises to 41% for 52 samples. In this situation, the illusion of improved performance can be manufactured by taking fewer samples. In the meantime, the true quality might have deteriorated. 

Since perspective plots like those in Figures 2-4 are subject to optical illusions, instruction as to their proper viewing is necessary. The parabolic surfaces of Figures 2a, 2c, 2d, 3a, 3c, and 4a all open downward. The viewer looks at the top surface of the plot rather than at the underside. Similarly, in the more planar plots of Figures 2b, 3b, and 4b the view is of the top surface of the plots. Figure 3d, which exhibits a minimum in the activity surface (see Table XI), rises to the right. The view is again of the top surface.

Intercomparison of the top and bottom sections of Tables XII, XIII, and XIV shows that for the L = 0 approximations the best set gives much better results than the Chebyshev at low orders, while the Cheby-shev at lower temperatures gradually improves as the order increases. It is obvious that the better approximations obtained by the Chebyshev (L = 5) for n = 1 and 2 are because of accidental cancellation of errors. We do not expect the Chebyshev (L = 5) generally to yield as good an approximation as the best set for a system. Such an example is illus-... 

Table 8 (Section 3) lists the several variants of which the structural abnormality has been determined. In addition, there are some abnormal fetal hemoglobins which are incompletely characterized. Figure 15 illus-...

Models of specific adsorption with single surface species (involving the specifically adsorbed ion) and with one site model of primary surface charging will be presented in this section. Many stability constants reported in Chapter 4 refer to such models. The present model calculations illustrate some aspects regarding the limitations of significance of the stability constants of surface complexes reported in Tables 4.1 and 4,2. The problem is similar as discussed in Section III for primary surface charging many different models represent the experimental data nearly equally well, but publication of one set of best-fit model parameters may create an illusion that the unique model has been found. 

Table 4-12 compares selectivities for single reactors. For some reaction systems a combination of stirred-tank and tubular-flow units may give higher selectivities than a single reactor of the same total volume. The combinations of number and arrangement of reactors and reaction systems are huge. However, the approach to selectivity evaluation is always the same and follows the methods described in Example 4-10. A simple illus-...
