Volume structure

The purchase orders, sales and distribution order quantities can be higher or lower each day depending on the available number of transportation units e.g. trucks or ships. The production quantity, however, each day is limited by production capacity and cannot be so easily changed day-by-day. These different volume structures need to be matched by integrating order schedules and availabilities of materials. [Pg.63]

We should note that this article by Ya.B. apparently remained little noticed in its time. In any case, we are unaware of any reference to it in the works of other authors. This is explained by the fact that its ideas were far ahead of their time. Only in recent years, due to the wide application of physical methods in studies of adsorption and catalysis, have the changes in the surface (and volume) structure of a solid body during adsorption and catalysis been proved. Critical phenomena have been discovered, phenomena of hysteresis and auto-oscillation related to the slowness of restructuring processes in a solid body compared to processes on its surface. Relaxation times of processes in adsorbents and catalysts and comparison with chemical process times on a surface were considered in papers by O. V. Krylov in 1981 and 1982 [1] (see references at end of Introduction). [Pg.9]

The encapsulated nanotubes produced in dichloroethane are shown in Fig. 9. Their morphology and the volume structure completely correspond to the mechanism of the fast formation of a nanotube and its simultaneous encapsulation proposed in paper [6],... [Pg.207]

Abstract. Free-volume structure in the lanthanum salt of laurinic acid in crystalline and liquid-crystalline states and an effect of dissolved Cgo molecules on the mean nanovoid radius and concentration were studied by means of the positron annihilation technique. La(Ci2H25COO)3 clathrate compound with dissolved C6o molecules was obtained, which is thermodynamically more stable than a simple mixture of components. Increased mean nanovoid radius (from 0.28 to 0.39 nm) after the inclusion of C6o molecules and concomitant decrease of the positronium annihilation rate by a factor of 2.7 indicate the decrease of the smallest nanovoid concentration. [Pg.753]

Fig. 34 shows the volume structure of vanadium-pentoxide [15]. The layered structure of the material is quite obvious and its electronic structure has been discussed in detail on the basis of diffraction data and theoretical investigations. [Pg.363]

However, the derivation of Equation 16 failed to take into account the free-volume ("structural") contribution to xy"(35), nor is the effect negligible with some polymer phases (36). In addition, there remains considerable doubt even as to what constitutes a "family" set of data e.g., with polymers that are liquid-crystalline. The characterization of polymer stationary phases via family-plot regressions of "inverse" gas-chromatographic retentions therefore invites further and comprehensive study. [Pg.272]

The described relativistic effects on the Kohn-Sham states form the background for a quantitative understanding of ground state properties like atomic volumes, structural properties and magnetic properties discussed in the following two sections. Quasi-particle spectra, on the other hand, are only in certain cases reasonably well approximated by the Kohn-Sham densities of states (so-called weakly correlated systems). In general, Kohn-Sham spectra and quasi-particle spectra may considerably deviate from each other. Nonetheless, they show the same symmetry. Thus, spin-orbit related splittings in... [Pg.759]

Inverse opal structures have been classified into three structures, the so-called residual volume structure , shell structure and skeleton structure . The residual volume structure is a perfect inverse opal structure, which can be produced if the whole space among the opal spheres is completely filled by the product materials. If the space is incompletely filled, the surface of the sphere template is covered by the product materials, and a shell structure is generated. Most amorphous compounds tend to form a shell structure. On the other hand, crystalline compounds tend to form a skeleton structure. [Pg.176]

It was hypothesized that cardiac size can be determined from energetics at the sarcomere level of structure, that is, the micro-unit [51]. The cardiac sarcomere was redefined as a sarcounit (Figure 8.22), a constant volume structure capable of axial stress generation. The function of the sarcounit was defined by its active and passive stress-length curves (Figure 8.23), with the active function corresponding to maximal activation. Maximal stress was modulated by a periodic time function, which was zero during diastole. [Pg.148]

Thus for solids having multiple peaks the above equation can be used to fit the data to optimally obtain the pore volume structural parameters pj, aj (j = 1, 2, 3,. .., N). From the optimization point of view, it is best to use a low value of N 2 or 3 first in the optimization and if the fit is not satisfactory then the parameter N is increased until the fit between the above equation and the data becomes acceptable. [Pg.130]
