Mode of composition description by equivalents or by weight per volume of water. Each description of water composition has to be accompanied by a statement of the units in which the data applied have been expressed, such as meq/1 ormg/1. This point is demonstrated by the following set of data ... 

Lumping of a discrete system into a lower order one is discussed, for the case of kinetics, in Section IV, A. In that section we also show that it is possible to lump a continuous system into a finite-order one. The important point is that, in dealing with discrete systems with large (or countably infinite) numbers of components, or with continuous systems, it is very usefiil to reduce the dimensionality of the composition description for practical calculations. For example, one could consider a subset of similar compounds, such as stereoisomers, to be a single compound, or lump, with the properties of the racemic mixture. More generally, we can project the composition vector onto a lower dimensional subspace that is not simply a partitioning of the compounds into subsets. One could also reduce dimensionality by some nonlinear parameterization rather than by linear projection, but we do not consider that case here. 

Ayahuasca shamanism is currently being romanticized in the West. Confused and dismayed by a physics of abstraction which divides matter into subatomic particles and then tells us that this "ultimate reality" obeys no laws we can recognize as rational, we are quick to turn to the equally egregious beliefs of the prescientific world. The question is can we really accept the Shamanic hypotheses of an alien culture Here, for example, is a composite description of what might be regarded as a representative South American ayahuasca curing session ... 

Wood creosote, coal tar creosote, coal tar, and coal tar pitch differ from each other with respect to their composition. Descriptions of each mixture are presented below. 

Based on direct observation of the bottom on numerous occasions and sieve analysis ( l-mm mesh) of box cores taken at FOAM, NWC, and DEEP (Rhoads et al., 1977 Yingst and Rhoads, 1978 Appendix 1), a composite description of the fauna at each station can be made. These fauna are shown schematically in Figs. 3, 6, and 9. 

The minimal compositional description for phase prediction in basin modelling, therefore, contains nine compounds in the gas range (N2, CO2, Cl, C2, C3, /-C4, n-C4, /-C5 and n-Cf), a pseudo-Cs (corresponding to all compounds eluting between n-C and n-C excluding n-Cj and including n-C ) and a plus fraction, C7+, which theoretically contains all other compounds present in the fluid eluting after n-C. ... 

We return now to the composite description of the system given by Eq. (21.7). The first term in Eq. (21.7) represents motion of the particle along the +x-axis with momentum + Px, while the second term represents motion of the particle in the — x direction with momentum — p. Confining the particle in the box forces us to use a composite description embodying motion in both directions. In a certain sense the particle is moving in both directions Or rather, we cannot decide from the description whether the particle is coming or going ... 

The coefficients of ij/i and i/ n the composite description are equal, indicating that these two contribute equally to the structure. The coefficient of differs from the other two, indicating that i/ ni contributes differently. The contributions of the three structures in HCl are estimated to have the values I, 26 % II, 26 % III, 48 %. The structures I and II are covalent structures, so we may say that the bond in HCl is 52 % covalent and 48 % ionic. A bond in which the ionic contribution is significant is called a covalent bond with partial ionic character.

Hence, the results adduced above have shown that the developed for microcomposites rheology description models do not give adequate treatment of melt viscosity for particulate-filled nanocomposites. The indicated nanocomposites rheological properties correct description can be received within the framework of fractal model of viscous liquid flow. It is significant, that such approach differs principally Ifom the used ones at micro-composites description. So, nanofiller particles aggregation reduces both melt viscosity and elasticity modulus of nanocomposites in solid-phase state. For microcomposites melt viscosity enhancement is accompanied by elasticity modulus increase. 

To simplify the studies on the composition and detonation properties of liquid explosives, their components will be divided into elements, oxidizers, combustible agents, and additives for composition description in this book. However, when detonation properties are discussed, the classification method will be based on their characteristics. 

In the scientific context of this book, generic and specific compositions are more meaningful than trade names. Therefore, compositional descriptions have been used throughout the book to characterize a given fiber, notably in discussions which relate structures to properties. Trade names have been used only when absolutely necessary. No attempt has been made to suppress the diversity of trivial names as they appear in the literature. A fiber by any name is still a fiber. In summary, the book introduces a unified view of advanced inorganic fibers to the aspiring materials science student and attempts to foster cross-fertilization among the experts in the field.

EDX is a useful tool for ES research, for example, for determining the atomic dispersion of a sample surface. However, EDX loses measurement accuracy because of (1) overlapping peaks, (2) detector resolution, and (3) emission of x-rays in all directions—they must escape the sample before being reabsorbed to be detected. The third factor can mean lower energy x-rays are collected with lower intensity than is actually present and rough morphology can mask elements resulting in inaccurate atomic composition descriptions [33].
