Saturation curves, fitting

With high temperatures the x values will not fit into the diagram. Then the hj values have to be calculated with smaller x values in order to draw the isotherms. In Table 4.6 these values are calculated with values x = x q% at various temperatures. Drawing the fundamental axes and isotherms with the instructions given above and the saturation curve with the help of Table 4.6 leads to the Mollier diagram in Fig 4,10u. 

In addition to COg, Cl and BPG also bind better to deoxyhemoglobin than to oxyhemoglobin, causing a shift in equilibrium in favor of Og release. These various effects are demonstrated by the shift in the oxygen saturation curves for Hb in the presence of one or more of these substances (Figure 15.35). Note that the Og-binding curve for Hb + BPG + COg fits that of whole blood very well. 

The uranium accumulation of tooth enamel is negligibly small while it can be appreciable for dentine. Hence, the efforts to determine the y-ray dose from the external dentine to enamel must be made to assess the equivalent dose, ED, considering the linear uranium uptake and early as well as late uranium uptake using polynomial formula for some fossils. Laboratory experiments indicated that fresh enamel did not accumulate uranium rapidly but dentine did.8182 The author argue that fitting to a saturation curve rather than a meaningless poly-nominal should be made in a model calculation of uranium-uptake.1... 

Figure 2.3 Sensitivities of rods and cones of the mudpuppy (a large aquatic salamander) retina. The graph shows the intensity-response curves, which were measured intracellularly from the retina of a dissected eye. The response is shown as a fraction of the response at saturation. A fit to the data is also shown. Rods are approximately 25 times more sensitive than cones. (Reprinted with permission from Gordon L. Fain and John E. Dowling.

Figure 8 Energy-level schemes and population transitions of CV in alcohols. The arrows with solid lines represent electronic transitions by pump light or the population transition from the higher ground-state to the lower ground-state. The arrows with dotted lines show electronic transitions by probe light. The indicator x means the saturation of the transition is the rate of population transition, which is calculated at 1/500 (fs)-1 by the curve fitting in Fig. 5. (From Refs. 1, 20.)...

The 02 equilibrium curves of asymmetric cyanomet hybrid Hbs with two cyanomet subunits—(a+CNp+CN)A(aP)cXL and (aP+CN)A (a+CNp)cXL—were also measured. However, it was not feasible to estimate reliable values of Kt and by curve fitting (Miura et al., 1987). We found that it was difficult to fit the 02 binding scheme with two binding constants over the entire saturation range of the... 

This curve-fitting approach for the determination of K is most accurate when the experimental data cover a range of r values that is broad enough to allow a significant degree of host saturation. In fact, it can be shown6 that the optimum... 

The carbon Is spectra were deconvoluted into six peaks using a nonlinear least-squares curve-fitting program. Peaks centered at 293.3, 291.2, 289.5, 288.3, 286.6, and 285.0 eV are due to CF3, CF2, CF-CF , CF, C-CF , and C, respectively. Large numbers of CF3 and CF2 groups and small numbers of C group are present in the polymer prepared in the monomer-deficient (energy-saturated) domain, and the F/C ratios are approximately 1.6. 

Fig. 15.12. I. Representative curve for theophylline using graph paper and A = 216 milliabsorbance units provided by Syva Co.. With the ABA-100 analyzer some of the calibrator points are above the projected straight line. II. A saturation curve for theophylline with the EMIT assay, using the ABA-100 in the normal kinetic mode, showed that the A is significantly higher. III. The data shown in II can be fitted to a Hill equation, using the computer program of Atkins (1973), giving A = 514, //i, = 300 /ig/ml, and n = 0.56. The various instrumental adaptations will result in different values of A, Hn2, and . From Dietzler et al., 1980 courtesy Dr. D. N. Dietzler and Clinica Chimica Acta.

Closed-form expressions for pore-scale saturation (Eq.[16] and [17]) for a unit cell with triangular central pore were fitted to measured saturation data of Hygiene Sandstone (Brooks Corey, 1964). A triangular central pore was selected to emphasize capillary contributions expected for sand pore space. An elementary unit c ell with dimensions l. = 0.033 mm, ex = 0.0012, p = 0.0001 was found to yield best lit to the measured dala as depleted in I ig. I 13a. flic resulting saturation curve is... 

Experiments indicate that mair depends linearly on M. Substituting the curve fit for this, and for the thermodynamic properties (Wairi0ut is taken as saturated at 34 C) ... 

Spectroscopic techniques as well have been used in demonstrating an interaction between CaD and CaT (Mani and Kay, 1990). For fluorescence studies, the sulfhydryl groups in CaD were labeled with acry-lodan. Addition of CaT to labeled CaD in the presence of Ca + produced nearly 50% increase in fluorescence intensity and the emission maximum shifted to 492 nm from 504 nm. Labeled CaD was titrated with CaT. Analysis of the titration curve by curve fitting showed that the best fit was obtained when the molar ratio of CaT to CaD in the complex at saturation was 1 1. A value of (9 2) X 10 M was obtained from the titration. However, there was no evidence of any interaction between CaT and CaD in the absence of Ca2+.
