Morphological indicators

Figure 3.17 shows the mechanical properties of the ACM-silica and ENR-silica hybrid composites synthesized from various pH, reproduced from the data reported by Bandyopadhyay et al. [36]. As morphology indicates, all the samples prepared within the pH range 1.0-2.0 are transparent, contain nanosilica particles, and are superior in tensile strength and modulus... 

Morphology of the cured samples was analyzed by SEM of the fractured samples etched with tetrohydrofuran (THE), which is a solvent for the rubber. Figure 11.24 shows the fracture surfaces of the PWE and PNE specimens. Whereas the PWE fracture surface presents an essentially homogeneous surface with only a few small voids present, small yet uniformly distributed cavities are seen in PNE samples. The PWE morphology is consistent with the high degree of intermolecular link between rubber and epoxy macromolecules. The PNE morphology indicates incomplete reaction between epoxy and rubber. 

The dry nematic solution exhibits a smooth texture after being annealed, with a field of disclinations at any glass-solution interface. A nematic phase produced by cooling the isotropic phase will exhibit a complex, mottled texture that slowly anneals to the smooth texture. The ratio Rvv(q)/ Hv(q) (for e = 20 deg.) for either morphology indicates appreciable orientational averaging of the orientation fluctuation. Photon correlation scattering on the... 

To elucidate the mechanism of increasing the sil-productivity due to an enhancement of weight of the silk shell in the total cocoon mass, the influence of 1-ethoxysilatrane and 1-ethoxy-3,7,10-trimethylsilatrane on some physiological and morphological indices of these insects has been studied89 (Fig. 17). 

Tables I and II report the morphological indices and the anisotropy measures obtained by Falcone et al. (2004b), respectively, from the stereological analysis and the eigenanalysis of the MIL tensor in order to characterize the inner crumb micro structure. By using these indices, it is possible to compare with high sensitivity the spatial arrangement of the cell walls in bread samples.

Fig. 15. The dependence of the amount of irreversibly chemisorbed carbon monoxide on the concentration of amorphous copper found by X-ray diffraction (Fig. 5) and by STEM (Table VI). The (10T0) prism planes of zinc oxide are exposed in the Cu/ZnO = 10/90, 20/80, and 30/70 catalysts and the (0001) basal planes of ZnO are exposed in the Cu/ZnO = 40/60, 50/50, and 67/33 catalysts. The different slopes for the two morphologies indicate slightly different concentrations of copper atoms on the prism and basal surfaces (43).

Administered subcutaneously, local tumors appear. Rat (oral) TDlo is 9100 mg kg 26 weeks. Rats repeatedly treated with cisplatin (2 mg kg twice a week for 4 weeks) exhibited neurophysiological and morphological indicators of peripheral neuropathy. 

Other types of microbial processes may also be important in the subsurface (Table 8.2). Microorganisms, such as sulphate-reducers have also been cultured from low-temperature fluids, and cell morphologies indicative of sulphide-, iron-and methane-oxidizing microorganisms (and protozoa) have been observed in vent fluids (e.g. Holden etal., 1998). Heterotrophs are also present at hydro-thermal vents, though little is known about their abundance and distribution, or... 

Unique characteristics of ferromanganese nodules and associated oxidation-reduction reactions have been used by soil scientists as morphological indicators to help identify hydric soils (see Chapter 3). These characteristics are termed by soil scientists as redoximorphic features however, various terms such as redox concentrations, redox depletions, and reduced matrix are synonymously used for the oxidation-reduction of iron and manganese and their respective concentrations. We prefer not to define these characteristics as redoximorphic features because oxidation-reduction reactions not only involve iron and manganese but also a range of elements that support biotic communities in the biosphere.
