Correction derivation

With the Laplace operator V. The diffusion coefficient defined in Eq. (62) has the dimension [cm /s]. (For correct derivation of the Fokker-Planck equation see [89].) If atoms are initially placed at one side of the box, they spread as ( x ) t, which follows from (62) or from (63). [Pg.881]

Berthelot showed that the mean compressibility between 1 and 2 atm. does not differ appreciably from that between 0 and 1 atm. in the case of permanent gases, and either may be used within the limits of experimental error. But in the case of easily liquefiable gases the two coefficients are different. According to Berthelot and Guye the value of aJ can be determined from that of aj by means of a small additive correction derived from the critical data, and the linear extrapolation then applied Gray and Burt consider, however, that this method may lead to inaccuracies, and consider that the true form of the isothermal can only be satisfactorily ascertained by the experimental determination of a large number of points, followed by graphical extrapolation. [Pg.159]

The coefficients produced still contain the implicit assumption that the value of AX = 1. Therefore to produce correct derivatives, it will still be necessary to divide the results from the formulas by (AX)", as above. [Pg.365]

The signal is enhanced using many of the techniques described in this text. The use of MLR, PCR, PLS and other background correction, derivatives, and the like can all be used to enhance the signal to noise between the component of interest for imaging and the background signal. Once this contrast is achieved the simple techniques described... [Pg.506]

The correct derivation of the remaining working equations involves replacing equation 13.1, which only takes into account the thermal volume increase, with equation 13.10, where both contributions are considered. The thermal volume change in equations 13.1 and 13.2 was renamed A v to distinguish it from the intrinsic (or chemical ) volume change Ac lcmv. [Pg.196]

In this book we present an alternative approach. Our discussion in this introductory volume will put particular emphasis on the traditional concerns, namely, determing the levels and intensities of the corresponding transitions. The approach we present retains, at least in part, the simplicity of a Dunham-like approach in that, at least approximately, it provides the energy as an analytic function of the quantum numbers as in Equation (0.1). If this approximation is not sufficient, the method provides corrections derived in a systematic fashion. On the other hand, the method starts with a Hamiltonian so that one obtains not only eigenvalues but also eigenfunctions. It is for this reason that it can provide intensities and other matrix elements. [Pg.260]

Another problem is the very high concentrations of reactants present in the low-conversion region. The correct derivation of any rate expression such as Eqs. 2-20 and 2-22 requires the use of activities instead of concentrations. The use of concentrations instead of activities assumes a direct proportionality between concentration and activity. This assumption is usually valid at the dilute and moderate concentrations where kinetic studies on small molecules are typically performed. However, the assumption often fails at high concentrations and those are the reaction conditions for the typical step polymerization that proceeds with neat reactants. A related problem is that neither concentration nor activity may be the appropriate measure of the ability of the reaction system to donate a proton to the carboxyl group. The acidity function ho is often the more appropriate measure of acidity for nonaqueous systems or systems containing high acid concentrations [Ritchie, 1990]. Unfortunately, the appropriate ho values are not available for polymerization systems. [Pg.49]

Many people assisted in the writing of this book Marylin Huff taught from several versions of the manuscript at Minnesota and at Delaware and gave considerable help. John Falconer and Mark Barteau added many suggestions. AU of my graduate students have been forced to work problems, find data and references, and confirm or correct derivations. Most important, my wife Sherry has been extremely patient about my many evenings spent at the Powerbook. [Pg.554]

The scaling argumentation has been outlined in some detail for the following reason the asymptotic behavior is fairly easily, and also correctly, derived by this technique. Often, however, the result is extended into a region of smaller q-values, down to u = 1184), and now the scaling argument comes to a conclusion which deviates strongly from the result of the analytic solution of Eq. (B.45). [Pg.80]

In the case of gases, properties may be tabulated til terms of their existence at 0°C and 760 mm pressure, To determine the volume of a gas at some different temperature and pressure, corrections derived from known relationships (Charles , Amonton s. Gay-Lussac s, and other laws) must be applied as appropriate. In tile case of pH values given at some measured value (standard for comparison), the same situation applies. Commonly, lists of pH values are based upon measurements taken at 25°C. The pH of pure water at 22°C is 7.00 at 25,JC, 6.998 and at 100°C. 6.13. Modern pH instruments compensate for temperature differences through application of the Nernst equation. [Pg.1536]

As mentioned above, the first correction must be reduced by a factor of about 0.7, and as a consequence, the resulting value, 2A d/lf, for the correction derived from the elasticity theory agrees with the value obtained... [Pg.807]

Comparison with experimental data reduction in limit of ideal gas to pV = nRT go through the critical point holding one variable constant, the residual expression should be correct derivatives give proper functions. [Pg.655]

Figure 19. As Fig. 18, but for the binding energy. A spin-orbit correction derived from the experimental fine-structure splitting of the I atom has been applied for the CCSD(T) results obtained with VTZ, VQZ basis sets and the extrapolation to the basis set limit (stars). [Pg.841]

This equation is simply the thermodynamic expression of the fact that the reversible work of separating the liquid and solid phases must be equal to the change in the free energy of the system. Therefore, a correct derivation implies that the three terms on the right of Equation 2 are the nature of free energies per unit surface area of the solid-vapor, liquid-vapor, and solid-liquid interfaces, respectively. [Pg.3]
