Numbers in tables

Procedure. Use Mathcad, QLLSQ, or TableCurve (or, preferably, all three) to determine a value of the ionization energy of hydrogen from the wave numbers in Table 3-4 taken from spectroscopic studies of the Lyman series of the hydrogen spectrum where ni = 1. 

Those exponents which we have discussed expUcitly are identified by equation number in Table 4.3. Other tabulated results are readily rationalized from these. For example, according to Eq. (4.24) for disk (two-dimensional) growth on contact from simultaneous nucleations, the Avrami exponent is 2. If the dimensionality of the growth is increased to spherical (three dimensional), the exponent becomes 3. If, on top of this, the mechanism is controlled by diffusion, the... 

The second column of numbers in Table 7.2 gives values for M2. 

Section 5.5 presents a data sheet for each cell in the taxonomy that contains failure rate data. Empty data cells are not presented. Filled data cells are listed by their CCPS Taxonomy number in Table 5.2 as an aid to the user. The CCPS data sheet format was developed from a number of sources including OREDA and IEEE Std. 500-1984. The format is presented in Figure 5.3, and its data elements are explained below ... 

Calculations for the minimum performance properties of drill pipe are based on formulas given in Appendix A of API RP 7G. It must be remembered that numbers in Tables 4-80-4-83 have been obtained for the uniaxial state of stress, e.g., torsion only or tension only, etc. The tensile stress resistance is decreased when the drill string is subjected to both axial tension and torque a collapse... 

We obtain the numbers in Table 9-II. In view of the precision of the data from which these ratios are derived, the ratios are far from constant. Now let us try the ratio...

The purpose of generating the numbers in Tables 1 and 2 is to ultimately determine a transfer coefficient. The transfer coefficient is used to calculate the exposure and finally a re-entry health risk to a chemical applied, in this case, to turf. Transfer coefficients are also calculated for other agricultural commodities to determine an estimate of risk when working in a treated crop, but this is not a topic of discussion for this paper. 

Fig. 11.4 shows the total ion current trace and some mass chromatograms obtained by flash evaporation pyrolysis gas chromatography-mass spectrometric analysis of the polluted sediment sample. All compounds present in this complex mixture were not listed. A selection was made to exemplify several aspects of the screening approach. The peak number correspond with the numbers in Table 11.1. Identifications were based on the same criteria as mentioned above. Although several components were shown to be real pyrolysis products, all the compounds are present as such in the sample and resulted from simple thermal extraction from the wire. This was shown in separate analyses using ferromagnetic wires with a Curie temperature of 358°C. 

What is really happening [23, 24] in the glucose —> mannitol cascade [19] can be seen from the quite complicated kinetic and molecular picture shown in Fig. 13.9, including three different types of kinetics (expressed in turnover numbers in Table 13.1) ... 

The numbers in Table 49 indicate that as the electronegativity of R increases, the chemical shifts of the sp3 and (for the most part) the sp2 carbon atoms a and ft to the nitrogen atom also increase. In all three cases, the pattern is reproduced and similar coupling constants are observed. The only exception appears to be carbon d in 115, which has approximately the same chemical shift as that of 114. 

Although the values obtained for J and K minimize the variance, we gain more insight into the meaning of the numbers in Table I by describing them in terms of an error bound for estimating asbestos level. A 95% confidence interval for the mean of the log-transformed data is Y + 1.96 SD(Y). In terms of untransformed data the confidence bounds are exp(Y - 1.96 SD(Y)), exp(Y + 1.96 SD(Y)). These limits determine a confidence interval for the median of the untransformed data. The error bound is calculated as... 

Because each orbital holds at most 2 electrons, the maximum number of electrons is twice the number of orbitals with a particular second quantum number. In Table 4-1, you must know the letters in the second column and the electron capacity in the last column. 

We show another aspect of these numbers in Table 15.3, where we detail the effects of resonance between the two Kekule structures and among all of the covalent structures for the two sorts o 2pz orbitals. The results suggest that within one structure the SCVB orbitals duplicate, to some extent, the effect of multiple structures, and the configurational mixing produces less energy lowering with them. 

Those familiar with the long history of the attacks on the question of the resonance energy of benzene may be somewhat surprised at the small numbers in Table 15.3. The energy differences that are given there are for just the sort of process that might be expected to yield a theoretical value for the resonance energy, but experimental determinations deld numbers in the range 1.7-2.3 eV. This is an important question, which we will take up in Section 15.3, where it will turn out that some subtleties must be dealt with. 

The properties of hydrofluoric acid.—Hydrogen fluoride is soluble in water between 0° and 19 4° in all proportions. The aq. soln. forms hydrofluoric acid the more cone, solutions fume strongly in air. The specific gravity of aq. soln. increases with increasing concentration of hydrogen fluoride up to a maximum 1 262 with soln. containing 75 93 per cent, of HF, and then decreases to unity as the concentration increases. The numbers in Table I are calculated from those of J. L. C. Eckelt,8 and of E. G. Hill and A. P. Sirkar. The table shows that the sp. gr. of a 63 per cent. soln. is 1 246 at 0°. Table II is due to C. Winteler. The contamination of the soln. with hydrofluosilicic acid greatly increases the density. 

The experimental results are summarized for each series (the series numbers correspond to the respective solvent numbers) in Table I. The first column is simply for reference, and the second is the normality of the lithium bromide. The third column gives the experimental equivalent conductance as calculated from the corrected specific conductances. 

If we return to our equilateral triangle example and apply the above rules, we obtain the numbers in Table 9-6.1. Using this table in conjunction with the character table (Table 9-7.2) and the decomposition rule ... 

The relatively small spread of the numbers in Table I (about a factor of six from smallest to largest) is remarkable in view of the considerable differences in venting phenomenology among the three shots and the variety of sources for the radiochemical data used. Danny Boy data were supplied by the U.S. Air Force Sedan data by Tracerlab, Nuclear Science and Engineering Corp., and Hazleton Nuclear Science Corp. Palanquin data were supplied by Lawrence Radiation Laboratory.
