Factor phenomenological

The main phenomenological difference in BM compared to MG is a broadening of the resonance peak at which, however, does not shift. The model calculations in Fig. 11 have been performed for spheres (N = 1/3) with filling factors of 0.5 and 0.9. The parameters, chosen to be equal for both models, are given in the figure caption. It immediately appears that we will not find any drastic difference in the interpretation of the data for the MG or the BM model. [Pg.101]

Interface slip factor a (m ). This factor is defined as a phenomenological parameter characterizing the lubrication behavior on the phase interface as a slide occurs. [Pg.686]

As demonstrated, Eq. (7) gives complete information on how the weight fraction influences the blend viscosity by taking into account the critical stress ratio A, the viscosity ratio 8, and a parameter K, which involves the influences of the phenomenological interface slip factor a or ao, the interlayer number m, and the d/Ro ratio. It was also assumed in introducing this function that (1) the TLCP phase is well dispersed, fibrillated, aligned, and just forms one interlayer (2) there is no elastic effect (3) there is no phase inversion of any kind (4) A < 1.0 and (5) a steady-state capillary flow under a constant pressure or a constant wall shear stress. [Pg.687]

Commercial program packages that either propose phenomenological models or fit a given model to data are easily available such equations, along with the found coefficients can be entered into program TESTFIT. It is strictly forbidden to associate the found coefficients with physicochemical factors unless there is a theoretical basis for a particular model. [Pg.210]

The issues that, according to these authors, should be included in research conducted in order to reach an understanding of the holistic nature of culture-bound syndromes are as follows identifying the nature of the phenomenon, situating the syndrome within the social context, the relation between the syndrome and the psychiatric disorders included in current classifications, and the social and psychiatric history of the syndrome. By following these steps it will be possible to correctly identify the phenomenology and subtypes of the syndrome, the social characteristics of the people who suffer from it and the risk factors, as well as to study the relation with other psychiatric disorders and even other syndromes that are specific to other cultures. [Pg.14]

All these theories provide the basis for using, as first approximation, the simple phenomenological equations to describe the ET rate constant k in D-B-A systems as k = k0 z d and the current flow 7 as 7 = / e /ld in molecular junctions, where d is the length of the molecule, and [1 is a decay factor. Although the decay... [Pg.90]

Where does the energy increase come from Can we offer an electronic description to the phenomenological term strain A priori, one can consider such factors as four-electron repulsion of filled in-plane orbitals and distortion/breaking of the acetylenic bonds as a result of their bending. [Pg.13]

The phenomenological treatment assumes that the Gibbs energies of activation Gox and Gred depend on the electrode potential , but that the pre-exponential factor A does not. We expand the energy of activation about the standard equilibrium potential >0o of the redox reaction keeping terms up to first order, we obtain for the anodic reaction ... [Pg.58]

Analysis of mass transfer in ternary media, until now, has mainly involved experimental studies of model and real food. Phenomenological models could be applied to obtain a more detailed description of the mechanisms involved. However, this would require an understanding of factors such as mass transport properties and transfer dynamics of different active compounds in concentrated solutions, which have yet to be characterized. [Pg.224]

In order to explain all the salient features of the key experimental results on ECT (viz. listed as 1. to 6. at the beginning of Section II, Phenomenology of ECT), Vijh25 proposed a detailed electrochemical mechanism in which electroosmosis of the tissue (and thence water movement from anode to cathode) and electrode reactions (thence necrosis of the tissue, pH changes etc.) play the dominant roles. In particular, he presented a model and some quantitative considerations that delineate Nordenstrom s idea of electroosmosis through the narrow interstitial channels lined with fixed charges as the mechanism of the electrochemical destruction of the tumor tissue.10 Also he examined the role of electrode reactions and other events as possible contributory factors, as follows25 in Section III.2. [Pg.482]

Since all three types of rate-constants are essentially affected by the same factors - although in a different way - it may be useful as a background to the following discussion to specify briefly the principal variables which are now known to affect the phenomenology of any cationic polymerisation these include the following ... [Pg.452]

In general there is no obvious way of separating the adsorbent molecule into two well-defined subunits, nor can one assume that all interactions between the ligand and the adsorbent molecule consist of only two electrostatic interactions. This is clearly the case for succinic acid or for DNA, where there is an infinite number of ways to define an unperturbed intrinsic binding constant. Therefore, the use of such factorization of should be abolished when a phenomenological approach is adopted. On the other hand, when using a molecular approach one may or may not use such factorization. In any case this is certainly not a necessity. [Pg.335]

To describe the impact of the x-values distribution type on the relative precision of relaxation rate estimates, we shall use a phenomenological factor fd. We expect it to be independent of all the other factors, but dependent upon the type of relaxation rate quantity to be determined (for example, the fastest- or the slowest-relaxing component in a multi-component mixture). [Pg.451]
