Dominance behavioral

What is observed is that there are significant changes in specific surface, but that they are relatively modest and cannot account for large changes in reaction rates in shocked powders. The observed behavior can be characterized into typical behaviors as summarized in Fig. 7.1. If comminution is the dominant behavior, the specific surface area will be observed to increase. Such a behavior is called Type a. If consolidation is the dominant behavior, specific surface area will be observed to decrease. Such a behavior is called Type b. In the most typical case, the specific surface increases at low pres-... [Pg.161]

Below are the MATLAB statements that we may use for visual comparison of exponential decay with different time constants. In rough engineering calculations, a pole may already exhibit acceptable dominant behavior if other time constants are 1/3 or less. [Pg.63]

Changing the diet of a fish may change the behavior of conspecifics it interacts with subsequently. For instance, if one of a pair of male brown bullhead, I. nebulosus (a catfish), is removed from the tank and fed beef liver instead of the usual trout chow and then returned to his partner in their original tank, the resident will behave differently than if the same male is reintroduced without a diet change. The former tank mate is now a chemical stranger. The behavior changes include loss of territory and more activity by the smaller, manipulated fish and more aggression and activity by the resident fish. These diet-dependent odors are not specialized pheromones, and yet they are probably important social chemical cues in the natural territorial and dominance behavior of bullhead catfish. Body odor is the more appropriate term (Bryant and Atema, 1987). [Pg.49]

There are other cases in practical electrochemical devices in which current distribution is important. Because of the interplay of interfacial and electrolyte resistance effects (primary and secondary current distribution, respectively , the detailed calculation involve much mathematics. Electroplating deep into crevices of the object to be plated is an example of where current distribution considerations often dominate behavior. Throwing power is a term that describes the degree of penetration of the current— hence the plating—into fissures and irregularities in electrodeposition. [Pg.395]

Zhang et al. studied the effect of conductive network formation in a polymer melt on the conductivity of MWNT/TPU composite systems (91). An extremely low percolation threshold of 0.13 wt% was achieved in hot-pressed composite film samples, whereas a much higher CNT concentration (3-4 wt%) is needed to form a conductive network in extruded composite strands. This was explained in terms of the dynamic percolation behavior of the CNT network in the polymer melt. The conductivity of extruded strand showed a hopping resistivity dominated behavior at low concentrations and a dynamic percolation induced network dominated behavior at higher concentrations. It was shown that a higher temperature can reduce the filler concentration required for the dynamic percolation to take effect. [Pg.161]

It is, of course, important to recognize that in general base catalysts exhibit bifunctional behavior and are therefore, strictly, amphoteric. The same general point can also be made concerning acid catalysts, and therefore the distinction between acidic and basic solid catalysts is made on the basis of dominant behavior, although in some cases, for example Zr02, there may be no single dominant behavior [10]. An illustrative example of this is the alkaline earth metal oxides, classical base catalysts, where oxide ions behave as bases and the metal cations... [Pg.819]

Different writers will speak of intentional or energized characters. It doesn t matter which term you use. What is important is that there be a palpable internal quality that pushes your character in a particular direction. This drive is as important to your story as the dominant behavioral or physical qualities you have given your character. The drive is the fuel for the plot. Without it your character is passive, acted upon rather than reacted to. A passive character can work in a short film, but by choosing such a character, you flatten the conflict and position your character as much as an observer as a participant. The result can be counterproductive in dramatic terms. The active, obsessed main character is more useful in the narrative. Once the plot begins, there is a natural tension between plot and character that will carry the audience easily through the story. [Pg.133]

Typical reservoir rocks are quite complex physically as well as mineralogically. The surface of sand grains available for interactions with injection fluids is a significant fraction of the total surface area however, the reactivity of sand with anionic surfactants is much less than that between clays and surfactants, so interaction with clays tends to dominate behavior. [Pg.21]

In lubrication with a liquid, the rheology of the lubricant at the functioning site is the dominant behavior transportation of the lubricant to that site, z.g. a bearing or a gear, by piping or spray nozzle is on the whole a routine matter and rarely affects the selection... [Pg.535]

The effects of annealing at 85 C (Figure 5) seems much more complicated. The peak at the glass transition temperature decreased rapidly and the broad peak dominated behavior above Tg. [Pg.346]

The fundamental behaviors of nanoscale materials may be completely different from those of bulk materials. Due to the very small sizes, especially at the low range of the nanoscale, surface and atomistic properties dominate behavior and one must be aware that bulk theories may not be completely applicable. Therefore, the study of nanoscale materials is a challenging route to the understanding of experimental observations. [Pg.734]

Ionic interactions (repulsive or attractive) can also dramatically alfect HDV. For charged polymers, ionic effects often dominate behavior, especially in aqueous solutions. Theoretical treatments for predicting polyelectrolyte dimensions and phase behavior are discussed by Barrat and Joanny (3) scaling theory for charged polymers is reviewed by Dobrynin, Colby, and Rubinstein (4). [Pg.9163]
