Level of generality

Provide a high level of general ventilation taking note of density and volume of gas likely to develop initially gases will slump, while those less dense than air (e.g. hydrogen, helium) will eventually rise. [Pg.260]

This represents an impractical level of general ventilation. Potential solutions to this problem include containing the toluene in a closed vessel or using local ventilation at the vessel opening. [Pg.91]

The basic issue is at a higher level of generality than that of the particular mechanical assumptions (Newtonian, quantum-theoretical, etc.) concerning the system. For simplicity of exposition, we deal with the classical model of N similar molecules in a closed vessel "K, intermolecular forces being conservative, and container forces having a force-function usually involving the time. Such a system is Hamiltonian, and we assume that the potentials are such that its Hamiltonian function is bounded below. The statistics of the system are conveyed by a probability density function 3F defined over the phase space QN of our Hamiltonian system. Its time evolution is completely determined by Liouville s equation... [Pg.38]

What constitutes a significant difference between two spectra When the differences are small, the answer depends on sample preparation and sample stability as well as accuracy of concentration determination, identification of and compensation for drift in the spectrometer, correct baseline correction, absence of bubbles in the sample, reproducible cleanliness of the cuvette, and the level of general handling procedures. Ultimately, an assessment of significance depends on the experience, competence, and confidence of the operator. [Pg.241]

There are several reasons for going first to this level of generality for the n-compartment model. First/ it points out clearly that the theories of noncompartmental and compartmental models are very different. While the theory underlying noncompartmental models relies more on statistical theory/ especially in developing residence time concepts [see/ e.g./ Weiss (11)]/ the theory underlying compartmental models is really the theory of ordinary/ first-order differential equations in which/ because of the nature of the compartmental model applied to biological applications/ there are special features in the theory. These are reviewed in detail in Jacquez and Simon (5)/ who also refer to the many texts and research articles on the subject. [Pg.98]

The ability of the ferritic alloys to resist chloride see is one of their most useful features in terms of corrosion resistance. During the 1970s, developmental efforts were directed at producing ferritic materials that could also exhibit a high level of general and localized pitting resistance as well. [Pg.792]

The claim that the needs and means of production "coerce" the relations of production into the capitalist mould remains obscure. It certainly cannot mean that capitalism is necessary for the further development of the productive forces. This, while no doubt part of Marx s view, does not enter into his explanation of the rise of capitalism - except at the level of general theory, as in the 1859 Preface. In the more detailed discussions of the emergence of capitalism, he argues that the real subsumption of labour under capital, with the concomitant development of the productive forces, was a mere, non-explanatory by-product of the process. Later, I suggest an interpretation of the first part of the passage, where Marx says that the introduction of capitalism is possible only at a certain level of social production. Here I emphasize the latter part, which leaves little doubt that the emergence of capitalist relations occurred prior to, and independently of, the development of the productive forces. [Pg.284]

As conceptualized by Holland and Nimmo, pharmacy practice can be categorized into five interrelated practice models (see Appendix).The five interrelated practice models can be simplistically delineated as clinical pharmacy, distributive pharmacy, drug information, pharmaceutical care, and self-care. The value-added functions of a pharmacotherapy specialist often depend on the successful utilization of knowledge and skills derived from three of the five basic practice models—clinical pharmacy, drug information, and pharmaceutical care. Therefore, the pharmacotherapy specialist often has to acquire additional training and education, beyond the level of general licensed pharmacists, that will allow them to provide specialized, value-added functions. [Pg.733]

It might seem strange to consider such a compound for medicinal use, but at the right dose levels and under proper control, there are very useful applications for this sort of action. The main application is in the relaxation of abdominal muscles in preparation for surgery. This allows the surgeon to use lower levels of general anaesthetic than would otherwise be required and therefore increase the safety margin for operations. [Pg.229]

This chapter is only semiformal. One reason is that the classification and the main ideas for the general definition should be of interest independently of any formalism some formalism was only introduced into the classification to prevent misunderstanding. Moreover, a complete formalization at the level of generality where it would be most useful still seems a formidable task, at least if this includes formulating and proving a lot of theorems that one would intuitively expect to hold, so that one can check that the definition reflects intuition satisfactorily. Readers primarily interested in the formalization might look at Section 5.4.3, Definition Sketches , and at the theorems sketched in Section 5.4.4 earlier. [Pg.47]

If one formalizes this chapter, one should not do it for signature schemes only. Two more levels of generality seem appropriate ... [Pg.47]

The level of generality of a model refers to the number of systems which are represented by the model. We adopt a definition given in [888], which states that a model is more general than another if it applies to more real-world systems. In case of work processes, we deal with non-material systems, both in the past and in the future, which arises the question of what should be considered a real-world system. Here, we regard a work process model B as more general than a model A if B applies to all work processes covered by A and if B applies to additional work processes which are not covered by A. [Pg.140]

Fig. 2.22) it links work process models and their components on different levels of generality. [Pg.150]

The adequate level of generality of the as-is process depends on the complexity of the process in consideration (see also Subsect. 2.4.5). For typical business processes, such as procurement processes for standard plant equipment, it is often possible to start with a generalized model, whereas generalized models of design processes are usually too complex to be created in a single step. Instead, models of one or several representative concrete processes should... [Pg.434]
