Entity with scope

The transformation was applied by the user to an entity which contained this such as it inherited the transformation as defined by the rule for transforming an entity with scope and the object referenced by the instance is outside the scope of the entity to which the user applied the transformation ...

Geometric and electronic properties are obviously mutually interdependent. These also influence, and are influenced by, the interaction of chemical entities with their environment (e.g., solvent). A number of molecular properties which are accessible by experiment result from, or are markedly influenced by, interactions with the environment (e.g., solvation, ionisation, partitioning, reactivity). For these reasons, the concept of chemical structure must be extended to include interaction with the environment. Table 1 summarizes the above discussion and may help broaden the intuitive grasp of the concept of chemical structure. Table 1 is also useful in that it allows a delineation of the matters to be discussed in this chapter. As indicated by the title, we will consider molecules at the geometric levels of modellization, either as rigid (configurational aspects) or as flexible geometric objects (conformational aspects). Broader conceptual levels (electronic features, interaction with the environment) lie outside the scope of this chapter and will be considered only occasionally. 

The metallurgical industry does not enjoy a similar degree of standardization. The processed materials are rocks of varied form and substance at the front end of the plant, and the products are also solids. There are many very different types of ore to be handled, and a wide variety of processes and products. Solid-phase materials transportation means that plants and their layouts tend to be customized, with scope for innovative solutions. Most ores are mainly waste which would be expensive to ship, so at least the front end of the plant has to be built at the mine, and be designed to suit the topography. The processed materials are for the most part relatively non-hazardous. When, as in the case of the platinum industry, highly toxic processes are necessary for the refining of the product, the refinery is usually built and operated as a separate entity from the concentrator and smelter, requiring a different approach and different behaviour. For the majority of low-inherent-hazard processes, the lesser inherent risks facilitate... 

The main significance of this is in terms of functional behaviour of the data structure. Deletion of an entity which has other entities in its scope means that all the enclosed entities are deleted at once. Similarly, passing an entity with a scope to a modeling function means that this function has access to all the entities in that scope. 

A structure attribute (parameter) of type S2 have entities with a scope as value. Besides, the scope consists of a REAL constant and a logical value. The structure attribute outside the scope has a 2-dimensional point as value (see "The type NIL" on page 24). 

This section describes systems which are at the border of what has been defined as being the scope of this review and therefore does not pretend to be comprehensive. Indeed, if there is a wealth of strictly inorganic materials and glasses into which NIR-crnitting lanthanide ions have been incorporated and which are clearly excluded from the review, there also exist a continuum between these materials and molecular entities, for instance coordination polymers and clusters which have been described in the two preceding sections. In continuity with these concepts are micro- and mesoporous materials into which lanthanide salts or complexes can be incorporated or attached. These are essentially zeolites and sol-gel materials, either conventional or the so-called inorganic-organic hybrids, as well as polymers. 

To amclude, the proposals mentioned here by no means represent the limits of the possible, but merely the most obvious next directions that we the authors conceive for the future development of the field. Certainly, with the range and scope of discoveries already recorded in the relatively short time that this class of compounds has been known, we feel confident in predicting that these macrocycles will continue to remain among the most intriguing of those macrocycle chemical entities currently available. 

Review papers on cyclic compounds with a phosphazene moiety have covered several areas, viz. metal complexes derived from organo-substituted, polymers with cyclotriphosphazene entities and chemistry of perfluorinated cyclo-phosphazenes. Azaphosphinines have been reviewed in the scope of the phosphorus-carbon heterocyclic chemistry. ...
