Comments on the Models

Fukuda. Indeed, while presenting their model, Sumaru et al. and Fukuda et also demonstrated that their results were compatible with the field-gradient force model, and their results were consistent with the experimental data for a variety of polymer systems. A further feature brought by the model in references 36 and 37 was the thickness dependence. 

In analyzing models, mention should also be made of those aimed at explaining experimental results for the diffraction efficiency in polymer films on which SRGs have been inscribed. This is the case of Naydenova et and Labarthet et However, it should be mentioned that in these models

Calculation of SS is allowed if there is a Po t in the model. A sum of squares divided by its associated degrees of freedom gives an estimated variance. Comment on the model underlying the calculations in Sections 3.1 and 3.3. Comment on the...

Model Using Jones Matrix Formalism Comments on the Models FACTORS INFLUENCING THE FORMATION OF SRGs... 

Traditional continuum, discrete, and mixed discrete-continuum models developed during the past few years have been reviewed in a number of papers (Bonaccorsi et al., 1982 Claverie, 1982 Tapia, 1982). In spile of their obvious shortcomings, there is still hope that the models proposed so far may be suitable for describing, at least partially, some of the features of the solvation phenomena. We shall present an application of theoretical models of solvation to the estimation of the influence of the environment on the shift of the tautomeric equilibrium A B. First, some comments on the models are given. 

A final comment on the model In the applications that were pursued so far [4 7], we assume that the variance, cr, is a time-independent scalar. There is no theoretical or computational restriction to make it so, and a potential extension to the model may make the variance a time-dependent tensor. The current choice is based on insufficient data to fit, rather than on true conviction of simplicity.

One last comment on the model—it relates not to causality but rather to increases and decreases in incidence of myocardial lesions. It seems that with high fat diets lesions will appear, irrespective of the oil type. Furthermore, 34% of the variation observed by Trenholm et a/. (1979) arises from differences among experiments [although analyses of covariance suggest that a considerable proportion of this variation (about 25%) can be attributed to differences in dietary fatty acid levels across experiments]. 

Mr. Gonzalez commented on the models used for deriving practical exemption/clearance levels and, citing the example of ICRP reference man model, questioned the need for the detailed modelling of all possible scenarios - a robust conservative approach should be sufficient for most purposes. 

Stream at two dams. In addition, samples of unmarked fish were collected from the river in a study to see whether the sample consisted of distinguishable groups of fish. The fish were returned to the laboratory, and the levels of and Zn were measured. A graphic model of the data was developed. Commenting on the model, the authors stated ... 

The above brief comments on the model of the lysosome-vacuolar apparatus help define the horizons for subsequent discussion. This discussion is centered on the problem of control of hydrolytic activity by the lysosome-vacuolar system. Examination of the model brings into focus the major elements which may be involved in controlling intracellular degra-dative activity, itself poised upon the normal functioning of the lysosome-vacuolar system. We may state here that control of acid hydrolase...
