Degrees of possibility

Attempts at environmental or health protection can yield only dubious results, if any, if they are based on suspect data. Therefore, a rigid quality control program is required for speciation analysis. Species alterations have to be avoided or minimized information on the degree of possible species changes must therefore be elucidated.32 39... 

Numerical studies [193] show that Eq. (5.54) provides a zeroth-order approxima-" tfon to the results of a full computation, which underestimates the degree of possible control in a realistic system. In addition, these results show that even for phase f tpfusion fields, which have widths on the order of wavenumbers, control is still - msive (e.g., Co 5). Examination of the experimental results on one-photon vs. 1-e-photon control show, however, contrast ratios on the order of 30% [76, 194], Tjhat is, the main experimental limitation, thus far, is due to experimental issues other (rihe partial laser coherence. 

A large degree of possible diversity provides a large information content, allowing cells to develop complex mechanisms of recognition. 

The ammoxidation process could be also used in the conversion of less-conventional molecules. Various examples are discussed in detail, and it can be remarked that owing to the relatively limited research effort, there is still a relatively large degree of possible improvement. The need for more reproducible results in some cases is also stressed. Nevertheless, this field could offer new interesting commercial opportunities. 

We have chosen for our metathetical study in the case of unsaturated disilanes the first generation of Grubbs catalysts because of the reduced degree of possible isomerization of the products during the time of polymerization [7]. 

Electrochemical evidence for the antiaromaticity of cyclobutadiene has been provided by Breslow and co-workers 17 The oxidation potentials for the hydro-quinone dianion 7 (—1.50 V, —0.68 V versus Ag — AgCl, at Pt electrode) are substantially more negative than the oxidation potentials of model 9 (—1.22 V, —0.45 V). In the 7 -8 conversion a dimethylenecyclobutene derivative, with only a small degree of possible cyclobutadiene character, is converted into a full cyclobutadiene, presumably partially stabilized by the ketofunctions. The data indicate that the cyclobutadiene resonance destabilization amounts to at least 12 kcal/mole, and an estimate of the true antiaromatic destabilization energy of 15—20 kcal/mole has been made17).

It is clearly not possible to make an overall judgement on this matter given the unknowns and uncertainties in the degree of possible damage being caused by acid pollutant emissions. 

Degree of possible harm (DPH), taking into account the worst possible case... 

This system has a particular focus. It applies only to personal injury, principally to employees, that could derive from machinery operation. As will be seen, all of the listings for Degree of possible harm involve personal injuries. There are no entries for possible damage to property or the environment. The terms used to establish gradations and scores in the Likelihood of occurrence and Frequency of exposure categories are comparable to those in previously cited risk assessment systems. They follow in Tables 14-16. 

Assume that in a company s annual shutdown for retooling and maintenance, a task is to be performed for which the likelihood of occurrence of a hazardous event was rated as Even chance could happen and the outcome would be Fatalities. In the illustration in Table 19, the ratings are purposely kept the same for likelihood of occurrence, frequency of exposure, and degree of possible harm. Ratings vary only for the number of people exposed. 

During the inspection, both conditions and procedures should be observed. If a hazard poses an immediate threat, preventative action must be taken right aw, not after the inspection. Notes are made, specifying details of the hazard, including its exact location. When completing the inspection report, it is a good idea to classify each hazard by degree of possible consequences (for example A = major, B = serious, C = minor). In this way, priorities for remedial action are established.

This may be connected with the degree of possible distortions of the lattice. 

The correlation of the rates of formation of arylmethyl free-radicals by molecular oibital theory will be discussed. Different levels of sophistication among pi-electron methods lead to conflicting conclusions concerning the degree of possible electron localization and the importance of non-bonded interactions with the principal radical site. The arylmethyl radical systems have been generated both by hydrogen abstraction... 

As discussed by Dubois and Prade (1988), the fuzzy set interpretation of possibility theory associates a degree of possibility with how well an object corresponds to a category into which it may be placed. From this perspective, the... 

In this expression, Ais a fuzzy set on a universe X, and the membership function n x) (interpreted as the degree of membership of an element x in the fuzzy set A) assigns a grade or degree of possibility, r x), that the element x is A. Thus, the fuzzy set interpretation of possibility theory provides a mathematical framework linking the concepts of fuzzy sets with formal possibility measures. 

The following power generator metrics (see Figure 7.14) are at the core of energy management, governing the degree of possible web surface effects by atmospheric plasma.
