Fluid flow. The tangential field acts on the nonuniform induced-charge (or Q distribution to produce quadmpolar ICEO flow, sucking fluid at the poles and ejecting it at the equator (Fig. 2c). The scaling of the flow can be easily understood as follows. Capacitive charging transmits a nonuniform voltage to the double layer of order EL, a firaction (1 + 5) of which is dropped across the diffuse part and... 

All this is a nice confirmation of the general picture. If the parton distribution functions in the nucleon are assumed known from deep inelastic scattering, one can use the Drell-Yan process to learn about the q and q distributions inside the meson information which otherwise would be very difficult to come by. 

A real prospect for a correct definition of molecular structure on the basis of quantum mechanics emerged thanks to a topological approach to the analysis of the electron density p(q) distribution in a system characterized by this density. This approach developed by Bader [19], based on the topological properties of the charge distribution in molecular systems, provides an invariant pattern of the distribution of chemical bonds between the atoms in a molecule and determines unambiguously the type of a molecular structure for both the classical (Butlerov-type) and the nonclassical (see Ref. [20]) molecular systems.

In the past, the interpretation of the NMR spectra was based on empirical correlations derived from the study of crystalline materials with known stiucture, [62] and, successively, on correlations with stmctural descriptors computed by ab-initio calculations on crystals or model clusters [63-68]. However, crystaUine systems generally exhibit a limited diversity of local stiuctures in contrast to the disorder and variety of stmctural units (different coordination numbers and Q distributions) present in multicomponent glasses. Moreover, the cluster approach does not account for the correlations between stmctural factors that exist in solids and disorder in glasses [69-71]. 

In the cases of phosphosilicate glasses (Bioglasses), the analysis of the correlation coefficients obtained for the linear correlations between the theoretical Si 8iso and the mean Si-O-T angle (R 0.55, 0.62, and 0.89 for Q, Q, and Si species, respectively) clearly indicates that the Q" distribution of the Si species is controlled by the nonrandom distribution of Na and Ca atoms in the glass [89, 95]. The worst correlations coefficients have to be ascribed to the irregular distributions of Ca ions around the different Si Q" species (its concentration is maximal around the and...

Lithium containing systems have a similar Q distribution, as shown in Fig. 8.8, suggesting that the V" +/Vtot ratio slightly affects the medium order of phosphorus ions, differently from NaVP systems where the content of V2O5 has strong effects on the glass structures. 

Observed and Calculated Q Distribution of an Acid Catalyzed Silicate Sol Prepared... 

With regard to structural evolution, perhaps the most important feature of the acid-catalyzed growth mechanism is that for most oligomeric species condensation is virtually irreversible. Tenuous, fractal structures are therefore kinetically stabilized, because there is no mechanism for restructuring and there is little monomer available to fill in voids. Unlike basic conditions in which dissolution-reprecipitation and the condensation process (monomer-cluster growth) naturally result in an inverted Q distribution (primarily Q and Q" species), acidic conditions produce a distribution of Q -Q" species as expected for classic polycondensation of tetrafunctional monomers. (See Fig. 33.) The importance of irreversible condensation to the evolving silicate structures was predicted by Her [1]. 

Note Q distributed dispersion. DBA double-bend achromat. TBA triple-bend achromat. 

To conclude this subsection we observe that the utilization of the standard Fermi-Golden rule rate expression, which leads to Eq. 1, is subject to a number of constraints. In particular, when the adiabatic electronic energy gap between P BH and P B "H is too small ( kT at room T) its use would be questionable. Nevertheless, even in this case an exact theoretical treatment of the problem is unlikely to reveal dispersive kinetics at room T from the Q distribution.
