Tensile strength of the fibers is also determined by the refinement of the fiber [14] (Fig. 4). Hydrophilic properties are a major problem for all cellulose fibers. The moisture content of the fibers amounts to 10 wt% at standard atmosphere. Their hydrophilic behavior influences the properties of the fiber itself (Table 3) as well as the properties of the composite at production [15]. [Pg.790]

As we noted earlier, caffeine affects not only arousal, but also other behavioral influences such as attentional focus. However, it now appears that these other effects may be secondary to the impact of the drug on arousal and that a multi-factorial model incorporating the inverted-U function may best describe that relationship. Most results in the literature to date are supportive of the biobehavioral model proposed here. However, research on the psychological effects of acute and habitual caffeine... [Pg.287]

Humans differ in sensitivity due to biological factors such as metabolic polymorphism, age, gender, health status, and nutritional status. These differences can be the result of genetic and/or environ-mental/behavioral influences. This intraspecies (interindividual) variation is greater in humans than in the more inbred experimental animal population. [Pg.258]

Oxytocin receptors are widely distributed in the brain (Insel et al., 1997). Brain receptors are biochemically identical to receptors found in uterine myometrium and mammary myoepithelium. There is a remarkable diversity across species in the neuroanatomical distribution and regulation of OT receptors. These receptors are heavily controlled by gonadal steroids, and the pattern of steroid regulation of OT receptor expression varies across species as well. This diversity of receptors may be the mechanism through which OT function, and thus the social behaviors influenced by that function vary across species. [Pg.199]

Acid Form - Pseudoliquid Phase Behavior. Owing to a high affinity for polar molecules, large quantities of molecules such as alcohols and ether are absorbed within the bulk phase of crystalline heteropolyacids. The amounts of pyridine, methanol, and 2-propanol absorbed correspond to 50-100 times that which can be adsorbed on the surface, while nonpolar molecules like ethylene and benzene are adsorbed at the surface only. Catalytic reactions of polar molecules occiu both on the surface and in the bulk, so that the solid heteropolyacid behaves as a highly concentrated solution, called a pseudoliquid phase . The dehydration of alcohols, various conversions of methanol and dimethyl ether to hydrocarbons in gas-solid systems, and the alkylation of phenol and pinacol rearrangements can all occur in the pseudoliquid. The transient response using isotopically labeled 2-propanol provides evidence for the pseudoliquid phase behavior of H3PW12O40. This behavior influences the selectivity, for example, the aUcene/aUcane ratio, in the conversion of dimethyl ether. [Pg.3395]

Changes in the particle structure have a strong effect on combustion behavior, influencing the particle temperature, mass transfer and pore diffusion rates, and consequently the rate-control regime of the process ( 5 ) Tlie changes in size and density of particles that have a homogeneous pore structure and small pore sizes (relative to particle size) are related to fractional burn-off, u, by... [Pg.245]

Liquid-liquid emulsions and other microstructured fluids have been the subject of much academic and industrial interest, for they offer a new area for scientific research, and their behavior influences many engineering technologies indeed they represent the backbone of several emerging chemical and biochemical processes. Colloids are in a transition domain between macroscopic and microscopic regimes of matter and... [Pg.98]

Experimental specific heats, C (p,T), are known to increase apparently without limit on the close approach to the critical point. This nonanalytic behavior influences a far greater portion of the P(p,T) surface than generally is appreciated. The thermodynamic relation between specific heats and the equation of state along isotherms is... [Pg.349]

These four attribute categories are presented in quadrant form in Figure 1. Each quadrant interacts and is interdependent with the other three quadrants. For example, cultural values influence personal values, and vice versa. Cultural and personal values influence behavior and behavior influences values. [Pg.12]

Warning sign is safety communication, and it is intended to communicate information about safety issues or problems. Its purposes can be referred to as safer world, provide information, influence behavior, and reminder, among which, the behavior influence is the effect issue, and that is to say, compliance behavior is the result of warning. [Pg.544]

As a melt is subjected to a fixed stress (or strain), the deformation vs. time curve will show an initial rapid deformation followed by a continuous flow (Fig. 1-6). The relative importance of elasticity (deformation) and viscosity (flow) depends on the time scale of the deformation. For a short time, elasticity dominates over a long time, the flow becomes purely viscous. This behavior influences processes when a part is annealed, it will change its shape or, with post-extrusion (Chapter 5), swelling occurs. Deformation contributes significantly to process flow defects. Melts with small deformation have proportional stress-strain behavior. As the stress on a melt is increased, the recoverable strain tends to reach a limiting value. It is in the high-stress range, near the elastic limit, that processes operate. [Pg.10]
