Detonation Wave Shape and Density. Properties This is the title of Chapter 5 in Cook s book (Ref 52 pp 91-122). On p 91, under the title "Theoretical Wave Profiles," Cook stated that the shape of the deton wave and the density- distance p(X) as well as the particle velocity-distance W(x) relations behind the wave front are of considerable importance. Langweiler (Ref 3a, quoted in Ref 52, p 91) assumed for the plane-wave case a simplified constant p(x) and W(x) contour followed by a sharp (presumable discontinuous ) rarefaction. He gave as the velocity of the rarefaction front the value (D + W)/2, where D = deton velocity and W = particle vel. He also stated that in an expl of infinite lateral extent, the compressional region or detonation head of wave should grow in thickness accdg to the equation ... [Pg.693]

Cefadroxil (also sometimes spelled cephadroxil), an antibiotic originally developed by Bristol-Myers (BM) and marketed under the trade names Ultracef and Duricef, had combined sales in the US of 100 million in 1988. A crystalline monohydrate (apparently discovered serendipitously), claimed in U.S. Patent No. 4,504,657 (the 657 patent) issued in March 1985, is described in the patent in terms of its X-ray diffraction pattern (Fig. 10.2). The improvement of this substance over the earlier known material included greater stability and high bulk density, properties which enabled the production of smaller pills. [Pg.301]

The term pyrolytic carbon can be applied to carbon filaments, carbon blacks, and carbon films, as well as to the more massive deposits which are the subject of this section. Pyrocarbon materials, made by chemical vapor deposition (CVD), vary in density, properties, and structure as much as the bulk materials discussed in 17.3.4.1. A heated hydrocarbon gas decomposes into an entire series of molecular species with a wide spectrum of carbon contents and molecular weights Within this pyrolyzing atmosphere, droplets form that pyrolyze and condense on a nearby surface, or large carbonaceous complexes may condense directly on the surface of the chamber. The former condition produces a fluffy, sooty, soft carbon, not far removed from carbon black, while the latter produces a hard solid carbon. The second of these materials is of primary interest here. The structure of the carbon produced by the CVD process has been shown to depend on the type of hydrocabon and its concentration, the pyrolysis temperature, the contact time, and the geometry of the pyrolyzing chamber. Of these, the pyrolysis temperature is perhaps the most important, but it is the nature of the chamber that conveniently divides the carbons produced into two distinct types. [Pg.286]

Most of the electronic structure calculations have concentrated on (1) the structure, (2) long-range interaction, (3) peptide-water interaction, and (4) electronic properties. These studies have also affirmed the central role played by the H-bonding interactions in protein. The possibility of the AIM theory to analyze a polypeptide or a particular portion of a peptide has been described [6,323,324]. The existence of H-bond in the peptides has been confirmed by the presence of corresponding bond path in the electron density. Properties associated with the path have also been characterized in terms of p r ) at HBCPs and ring CPs. [Pg.31]

It is appropriate to mention here that a generalized picture of H-bonded interaction has emerged from the electron density properties at HBCPs. [Pg.35]

The local distributions of dislocation densities indicate that the dislocation microstructure is not homogenous. The local dislocation density plotted in Fig. 14 suggests the existence of two sub-areas with different dislocation density properties. In the first sub-area, the dislocation density is much higher than the average density consequently distinguished peaks appear. In... [Pg.344]
