The dual-cycle mechanism, recently introduced by Svelle et al. afto confirmation by theoretical calculations [91], combines the features of both mechanistical approaches (Fig. 14) [29,92,93]. This mechanism represents the most recent state on olefins formation from methanol and allows the best fitting with the experimental data. [Pg.207]

For the SDP problems arising from the variational calculation, in which we are interested, the theoretical number of floating-point operations required by parallel Primal-Dual interior-point method-based software scales as [Pg.116]

The key feature is likely the dual nature of the U 5f-states, i.e., the presence of both localized and delocalized U 5f-electrons. The theoretical investigation proceeds in three steps. Firstly, band-structure calculations have been performed starting from the self-consistent LDA potentials but excluding the U 5f j = 5/2, = 5/2 and jz = 1/2 states from forming [Pg.200]

Section 8 summarizes separation factors obtainable in isotope exchange reactions and their temperature dependence. The latter is the key property in dual-temperature exchange processes. Section 9 develops equations to be used for calculating the number of theoretical stages needed in exchange separation towers. [Pg.712]
