Oxygen calculated changes

Figure 1.29. Calculated changes in the S 0 values of volcanic rocks (5 0 = +7.0%c) as a result of equilibrium oxygen isotope exchange with waters of different initial compositions. The dotted areas represent the ranges of rocks in the zeolite and the sericite-chlorite zones (Green et al., 1983). Figure 1.29.

Figure 12.32 shows the results of model calculations of the effects of the increased aerosols for October 1986 at 43.5°N (Solomon et al., 1996). The calculated change in the odd-oxygen loss rate when the measured aerosol particle surface area is incorporated into the... [Pg.693]

FIGURE 12.32 Calculated change in loss rate for odd oxygen as a function of altitude in October 1986 at 43.5°N compared to the predictions for a constant particle concentration typical of winter 1978-1979 levels (adapted from Solomon et al., 1996). [Pg.693]

Figure 4.5. Calculated change in the sum of the one-electron energies using the Newns-Anderson model. The parameters are chosen to illustrate an oxygen 2p level interacting with the d states of palladium with a varying d band center, ed. In all cases, the number of d electrons is kept fixed. The corresponding variations in the metal and adsorbate projected densities of states are shown above. Notice that the adsorbate-projected density of states has only a small weight on the antibonding states since it has mostly metal character. Adapted from Ref. [4]. Figure 4.5.

The time to steady-state was calculated for the oxygen concentration change at z = 1 km (i.e., depth 3 km see Figure 12) as the time when the concentration referred to the initial steady-state (C — C =0) has attained the value of 95% of the new steady-state, Equation 51, referred to the same initial point (Ct=,< — C = o). [Pg.69]

In a seagoing ship hull, the steel surface exposed to sea water is under diffusion control by dissolved oxygen. The limiting current for oxygen diffusion changes by an order of two when the speed of the ship increases from 10 to 15 mph. (i) How does the limiting current density for oxygen reduction vary Calculate the cathodic current required for protection, (ii) For the above system, surest the nature of cathodic protection that is ideal (constant current or constant potential) and why ... [Pg.610]

The results of the calculations exhibited a change of -20.3 ppm when moving from a gas to liquid phase for the oxygen of the water molecule, compared to the -36.1 ppm that is observed experimentally.The calculated change for hydrogen was -2.28 ppm compared to that observed experimentally of -4.26 ppm.i Thus, the calculations reproduced only approximately 50% of the experimentally observed changes. Clearly, improvements in the method are needed. A different force field may well be required, but this possibility was not investigated. [Pg.242]
