It is evident from the concepts presented that no tortuosity factor is involved in this model. The actual path length is equal to the distance coordinate in the direction of diffusion. To apply Eq. (11-25) requires void fractions and mean pore radii for both macro and micro regions. The mean pore radii can be evaluated for the micro region by applying Eq. (11-21) to this region. However, must be obtained from the pore-volume distribution, as described in Sec. 8-7. The mean pore radii are necessary in order to calculate 2>k)m om Eq. (11-27).

Some empirical parameters describing interactions between solvents and solutes, or the dependence of the reactivities on changes of the solvent, are important for a general explanation of molecular interactions (in particular non-covalent interactions) because they introduce the idea that the immediate neighbours of the solute (or of the reaction centres) are a micro-region of great interest. Classical parameters which consider the medium as a homogeneous system may be hardly used to explain physical and chemical properties of solutes in solutions. 

BS particles, and H2SO4 in the paste pores. These processes are similar to the ones illustrated in Fig. 9.22. The H2S04/Ph0 ratio deereases in the plate interior, because part of the H2SO4 reacts and water is produced as a result of sulfation of the PbO, 3BS and IBS phases. The SEM pictures (Figs. 9.12—9.15 and 9.19—9.21) evidence that the processes of sulfation of the paste and of the paste/grid interfaee proeeed at different rates in the different parts of the plate volume, and lead to the formation of different phases in the different micro-regions of the paste. 

In the micro-regions rich in silica the formation of cuspidine chlorine analog Ca4[Si202]Cl2 and also Ca2[Si04]Cl2 is possible. The first is decomposed at about 1000 °C and the second at 950 °C. 

However, how the morphology of the superhydrophobic PMMA surface was formed is still a question and needs to be explored further. As discussed above, after modification with ethylenediamine-anhydrous ethanol mixture for 3 h, the PMMA plates had a water CA of 55.9 0.9°, a value between the water CA values of pristine PMMA and NH2-terminated self-assembly monolayer. Therefore, we believe that the methyl ester functional groups on the surface of PMMA plates, when processed in ethylenediamine-anhydrous ethanol mixture, did not react with ethylenediamine completely and only a part of surface ester groups participated in aminolysis reaction. So, in the following reaction with stearic acid, stearic acid would anchor and crystallize preferably in the NH2-modified micro-region, which will induce the formation of flower-tike structures. The ATR spectra also indicate the same information. The spectra (a) and (b) in Fig. 6 are the attenuated total reflectance (ATR) infrared spectra of pure PMMA and NH2-modified PMMA, respectively. The major observations from comparison of spectra (a) and (b) are the presence of the amide I... 

Tumor hypoxia predominantly results from an inadequate perfusion due to severe structural and functional abnormalities of the tumor microcirculation (see Fig. 4.6 for reviews see Vaupel 1994a, 2004b, 2006, Vaupel et al. 1989). Hypoxic (micro-) regions are heterogeneously...
