INDEX pressure effects

Our discussion here explores active connections between the potential distribution theorem (PDT) and the theory of polymer solutions. In Chapter 4 we have already derived the Flory-Huggins model in broad form, and discussed its basis in a van der Waals model of solution thermodynamics. That derivation highlighted the origins of composition, temperature, and pressure effects on the Flory-Huggins interaction parameter. We recall that this theory is based upon a van der Waals treatment of solutions with the additional assumptions of zero volume of mixing and more technical approximations such as Eq. (4.45), p. 81. Considering a system of a polymer (p) of polymerization index M dissolved in a solvent (s), the Rory-Huggins model is... [Pg.173]

Classic fluorescence lifetime instmments are used for an extremely wide range of applications. Lifetime changes induced by solvent interaction, conformational changes and different binding state to proteins, peptides or lipids are described in [134, 269, 271, 336, 380, 395, 404]. The dependence of the lifetime on the refractive index of the environment was investigated in [142, 407, 483, 484]. Pressure effects on the lifetime are shown in [491, 492]. Electron and proton transfer are... [Pg.68]

ABSTRACT The relationship between gas desorption index of drill cuttings Kj and gas pressure was measured for four coal samples from Daning mine based on the measuring principle of index Kj. Then the variation characteristics of kj with gas content W were researched combined the proximate analysis of these samples. The results showed that There is a significant correlation between Kj and W This correlation can be expressed by an exponential function, and the two also are in accordance with the linear relation when the gas constant is low The results provide critical value study of coal and gas outburst prediction index and effective inspection index for regional outburst prevention theoretical with guidance. [Pg.907]

The pressure effect on a laminar flame velocity cannot always be reliably determined in experiments with hydrogen-containing mixtures. Contradictory conclusions for normal flame velocity dependence on pressure can be found in the literature. In technical applications, power functions for a flame velocity dependence approximation on temperature and pressure are used. Such power functions are called thermal and baric indexes respectively. [Pg.28]

Figure 14-8 shows the effect of speed and load intensity on the flash temperature index. These curves are general in nature, since scoring is a function of pressure angle, lubrication, and tooth size. [Pg.528]
