Reality hierarchy

It is worth reconsidering the reaction modelling hierarchy of Figure 1 in the light of the foregoing discussion. Clearly, the relevant global models are easily formulated and nicely adaptable to process engineering models. However, they do so at the expense of chemical fundamentals and therefore can only be used as interpretative correlations. At the other extreme, mechanistic models provide detailed chemical analyses of reaction systems. However, they bear the burden of extensive computational requirements and face the reality of the paucity of experimental data. Molecular models provide a convenient compromise between the two. The CPU requirements are reasonable, while at the same time chemical fundamentals are retained because of the implicit connection to reaction mechanisms. [Pg.310]

In an atom with an open valence shell valence-valence and corevalence correlation effects considerably affect the hyperfine structure. Since all these effects are intertwined in reality the MBPT analysis orders these mutual interactions in a hierarchy and their relevance corresponds to the order in which they occur. [Pg.309]

General systems theory is a set of related definitions, assumptions, and propositions which deal with reality as an integrated hierarchy of organizations of matter and energy. General living systems theory is concerned with a special subset of all systems, the living ones. [Pg.344]

In reality, there are at least two possible solutions to this critical mass problem that don t involve increasing the project team hierarchy, but both depend on exceptional situations. With an extraordinarily broad-minded, open, and cooperative project team large yet functional meetings are sometimes possible, but it s not something one can always count on. Alternately, an autocratic project team leader can run effective large meetings, but if he s that much of an autocrat, why have a project team at all ... [Pg.165]

We need to choose which variables and family of functions to utilize, and we make those choices correctly if we think that the variables and function hierarchy selected somehow map onto the basic physical reality at hand (Norton 2003 656). [Pg.115]

The critical infrastructure and critical technology in the human system ensure services in territory, i.e. certain quality and hierarchy of public services. A measure of level of services in a territory consists in a judgement of different sorts of services that have different importance from the viewpoint of live and security of humans in the integral sense. There is a reality that different sorts of services are ensured by different partial infrastructures that are dependent because among them there are interdependences. This fact always manifests at severe disasters (beyond... [Pg.1775]

The figure shows that if you can prevent one of these conditions, then you can prevent the accident. Of course, it may not be so easy to ensure that the one that you choose actually holds up. The figure implies that the human operator committed an unsafe act (an active failure or action), which caused the accident. In reality, there were a number of other latent conditions that could have also contributed to a particular accident. These latent conditions may have existed for months or even years. When you investigate an accident, it is important to go down to the root causes, and not just the symptoms or what appears obvious, to ensure that all the accident mechanisms have been identified. Again, refer to the hazard reduction precedence in Chapter 2 on the hierarchy of hazard controls. [Pg.283]

It seems that in this accelerated hierarchy of various levels of interaction gene interaction is only a partial aspect of the problem and is more a concern of genetics than of developmental biology. In reality. Professor Korochkin s book demonstrates that gene interaction is an essential aspect of the developmental process, or, in other words, the realization of the heredity information occurs only through gene interaction. [Pg.327]

This is the person, or persons, that have the authority to accept potential mishap risk. Typically, the mishap risk for a hazard falls into one of several different possible levels based on the risk matrix, and a person of higher rank or authority is required to accept the corresponding level of risk. DoDINST 5000.2 states that high, serious, medium, and low risk must be accepted by the CAE, PEO, PM, and PM, respectively. In theory, the risk level should be pushed down, through design measures, to the lowest level in order that the risk can be accepted by the lowest level decision authority. In reality, this is not always possible due to various system constraints, thus requiring a decision authority hierarchy. [Pg.331]

In 1986, a division of BR was formed to manage this information, in order that the data could be structured to aid retrieval. This division was known as the Engineering Data Section. Hierarchies of information were created which became the forerunner to structured computerised databases. With the development of mainframe computers and relational databases, the concept of complete catalogues of structured data, made available nationally at the touch of a button started to become a reality. [Pg.57]

The main problem is that a large fraction of wasted food is perishable and not always edible. This makes collection, processing, and transportation for human consumption very difficult. In fact, Waste prevention at the top of the waste hierarchy is really a catchphrase without much content, the use-and-throw society is a reality with its huge turnover, creating the ever increasing mountains of waste" (Tjell, 2005). [Pg.622]
