Distribution, complimentary

Based on the above-mentioned assumptions, the mass, momentum and energy balance equations for the gas and the dispersed phases in two-dimensional, two-phase flow were developed [14], In order to solve the mass, momentum and energy balance equations, several complimentary equations, definitions and empirical correlations were required. These were presented by [14], In order to obtain the water vapor distribution the gas phase the water vapor diffusion equation was added. During the second drying period, the model assumed that the particle consists of a dry crust surrounding a wet core. Hence, the particle is characterized by two temperatures i.e., the particle s crust and core temperatures. Furthermore, it was assumed that the heat transfer from the particle s cmst to the gas phase is equal to that transferred from the wet core to the gas phase i.e., heat and mass cannot be accumulated in the particle cmst, since all the heat and the mass is transferred by diffusion through the cmst from the wet core to the surrounding gas. Based on this assumption, additional heat balance equation was written. [Pg.188]

Through the analysis of adsorption isotherms and 129Xe NMR results of the co-adsorbed xenon, we have shown that the dispersal of benzene molecules depends on not only the cation distribution but also the amount of benzene adsorbate within the supercage of zeolite adsorbents. We have also demonstrated for the first time that this well known indirect technique has the capability not only to probe the macroscopic distribution of adsorbate molecule in zeolite cavities but also to provide dynamic information about the adsorbate at the microscopic level. Conventional H and 13C NMR which directly detect the adsorbate species, although providing complimentary results, are relatively less sensitive. [Pg.286]

The idea that the most important factor in enzyme catalysis is associated with electrostatic effects, has received strong support from simple MEP calculations. Such calculations indicated that enzymes provide complimentary environments to the charge distribution of their transition states. In fact, the crucial importance of electrostatic effects receives overwhelming support from simple logical considerations. That is, in order to catalyse reactions, enzymes must interact with the changes of the reacting... [Pg.285]

Our recent immunocytochemical studies indicate that the 5-HT innervation of the cortex exhibits less interlaminar specificity than NE terminals and is, in general, complimentary to that of NE inputs (Fig. 27). The serotonergic innervation of PC is very heavy by comparison to DA and NE. 5-HT fibers are especially heavy in layers I and III and the endopiriform nucleus. The density of 5-HT fibers progressively decreases in the deeper parts of layer III. Layer II by contrast, is sparsely innervated. 5-HT fibers in all layers are relatively short, with a tortuous, convoluted orientation and exhibit more varicosities than NE or DA fibers. As with NE, there is little variation of 5-HT fiber distribution or density at different rostrocaudal levels of PC. [Pg.552]

If the size versus impurity analysis shows that relatively greater amounts of impurity reside in the largest crystal size fraction, this can indicate the presence of inclusions, or other crystal size-dependent defects. In such a case, a complimentary technique, such as optical microscopy, can be applied to confirm the type and distribution of defects in the crystalline phase. [Pg.79]

Cathodic protection is always applied as a complimentary protection to the coating. The coating reduces the amount of current necessary to be impressed for cathodic protection. Coating is usually employed to distribute current evenly so that precise protection of the structure can be accomplished. It also levels out the uneven distribution of current at... [Pg.618]

The important information that can be provided by IR spectra is the molecular orientation in/on polymer films, which include SAMs as the specific case (Section 3.11). In the case of self-supporting anisotropic films, the linear dichro-ism is usually calculated from normal-incidence transmission spectra measured at two mutually perpendicular positions of the polarizer [684], Obviously, this approach is insensitive to the modes perpendicular to the film surface. This problem is circumvented by using a combination of the normal-incidence transmission with metallic IRRAS [727], since these methods have complimentary selection rules — the modes whose TDMs are parallel or perpendicular to the surface are active in transmission or IRRAS, respectively. This technique was used to study the MO in ultrathin n-aUcylacrylamide LB films [727, 728]. A strong biaxial distribution was found in these LB films in which the carbon-hydrogen chains are inclined in the dipping direction [727]. [Pg.605]

The theory associated with these two complimentary mechanisms predicts N,-, the rate of a particle of type i, small or large (i = S or L), falling into a layer below (Nj) based on the statistically determined size distribution of void spaces in the layer below and local shear rate ... [Pg.368]
