Heuristic purposes

Figure 8.6 The process of enacting and co-emergence. The living structure and the environment are represented here as separate domains only for heuristic purposes. In reality, according to the theory, they are one unit.

In this hierarchical scheme, the dorsolateral prefrontal cortex is a head ganglion for deliberate decision making, an arbiter and executor of conscious processing, and a director of what we call our will. No doubt oversimplified and minimizing for heuristic purposes what must be constant and massively parallel interactions with other parts of the system, this model is particularly attractive in the context of our conscious state paradigm. 

To complete the discussion of factors involved in the design of gas-solid heterogeneous catalytic reactors we will examine several aspects of the kinetics of chemical reactions occurring in the presence of a catalyst surface. We consider, for heuristic purposes, the equilibrium reaction ... 

DOM participates in several reactions that occur in the extracellular environment. In contrast to intracellular reactions, environmental reactions are more or less nonspecific (excepting some enzymatic reactions), unregulated, and opportunistic. For heuristic purposes, these reactions can grouped into three categories hydrolytic, redox, and associative. 

Clearly, this is onty a crude way of stating the point, chosen tor heuristic purposes only. 

Figure 17.20 summarizes schematically the effects of polymers on an idealized colloid. The colloid is idealized to the extent that its surface, chameleon like, can change from being inert to strongly anchoring as is required for heuristic purposes. 

Kekule was not the only important protagonist in the rise of the set of ideas that was ultimately consolidated under the rubric "structure theory" for example, in addition to Williamson, Adolphe Wurtz, Emil Erlenmeyer, Hermann Kolbe, and Edward Frankland also played vital roles. At the time of the birth of the theory all of these men occupied respected positions in their field. Chapter 5 looks at four outsiders— Archibald Couper, Joseph Loschmidt, Aleksandr Butlerov, and Alexander Crum Brown—who at this time were relatively new to the science, but who made their marks in sometimes transformative ways during the years 1858-64. All four had definite ideas on how molecules should be conceived by the scientist and best represented for heuristic purposes. A tour of these figures provides a fuller understanding of the range of responses, opportunities, and creative options that were available during these tumultuous years in the science, and suggests par-... 

The scope of this article does not allow for an adequate discussion of the view of marriage in ancient IsraeL The only thing we know for sure is that men and women were married, but the exact nature of that arrangement is complex, whether we focus on legalities, ideal depictions or as actually experienced in ancient Israelite society. For the present heuristic purposes, I take as a point of departure that the marriage metaphor in the prophetic literature is meant to work within the parameters of an ideal, unequal and hierarchical concept... 

For heuristic purposes we consider a zeolite crystal and assume that heat transfer resistance is wholly within the gas film surrounding the crystal and that intracrystalline diffusion is the rate-controlling mass transfer process. The set of equations which have to be solved to yield an expression for the... 

Probably, Gabriel de la Puerta s critical remarks were not shared by all the Spanish authors. However, he highhghted several contemporary perceptions about the relevance of Mendeleev s periodic system as a physical law, which could be refined and used for heuristic purposes, but also, as we will discuss later, for supporting broader-ranging views concerning atomism, inorganic Darwinism, and...
