Paris relationship

Rigid PVC is a polymer that conforms well to the Paris relationship. 

Rates of CF crack propagation are uniquely defined by the linear elastic fracture mechanics stress intensity factor range that combines the effects of applied load, crack size, and geometry 17,40. The similitude principle states that fatigue and CF cracks grow at equal rates when subjected to equal values of AK [6-S]. The dal N versus AK relationship may be complex however, an effective approach is based on a power (or Paris) relationship of the form [4/]...

In the first pari of this project, the analytical form of the functional relationship is not used because it is not known. Integration is carried out directly on the experimental data themselves, necessitating a rather different approach to the programming of Simpson s method. In the second part of the project, a curve fitting program (TableCurve, Appendix A) is introduced. TableCurve presents the area under the fitted curve along with the curve itself. 

An empirical relationship between the rate of crack growth and the stress range has been formulated (Paris - Erdogan Law) ...

Their results show that the redox couples in a sample generally failed to achieve equilibrium with each other. For a given sample, the Nernst Eh values calculated for different redox couples varied over a broad range, by as much as 1000 mV. If the couples had been close to redox equilibrium, they would have yielded Nernst Eh values similar to each other. In addition, the authors could find little relationship between the Nernst values and Eh measured by platinum electrode. Criaud et al. (1989) computed similarly discordant Nernst Eh values for low temperature geothermal fluids from the Paris basin. 

In the conclusion, the relationship of disciplines to schools and traditions is discussed, both in the particular instances of the Paris and London-Manchester schools and in the more general history of Continental and Anglo-American science, using elements of the disciplinary identity schema developed at the beginning of the book. I end with an inquiry into the views of mid-twentieth-century theoretical chemists and chemical physicists on the commensurability of their disciplines, the reducibility of chemical explanation to physical principles and laws, and the distinctiveness of chemistry from physics.

Moseley s work not only shed much fight on the periodic system and the relationships between known elements and the radioactive isotopes, but was also a great stimulus in the search for the few elements remaining undiscovered (11). One of the first chemists to utilize the new method was Professor Georges Urbain of Paris, who took his rare earth preparations to Oxford for examination. Moseley showed him the characteristic fines of erbium, thulium, ytterbium, and lutetium, and confirmed in a few days the conclusions which Professor Urbain had made after twenty years... 

Some of us don t read fiction [and] we will be feasting on Walter Arcades Project for years to come...

The Arcades Project captures the relationship between a writer and a city in a form as richly developed as those presented in the great cosmopolitan novels of Proust, Joyce, Musil and Isherwood. ... 

The molecular and genetic relationship between enzyme induction and repression was clarified by the genetic research of Jacob and Monod at the Pasteur Institute, Paris (see reference l7>). Their classic work led them to develop the operon hypothesis for the control of protein synthesis in prokaryotes, which has since been verified by direct biochemical experiments. 

The variation in the TR with depth for three other natural maturity sequences (Mahakam Delta, Paris Basin, North Sea) is plotted with that for the Monterey Fm. in Figure 4. While the geothermal histories of these sequences are different, there is in each case a strong relationship between maximum temperature experienced by the sample and depth. Depth is therefore used here as a common maturity axis for comparative purposes. Each of these sequences show a slight but significant decrease in this ratio with increasing depth. The extent of the decrease is, however, less dramatic than that for the Monterey sequence due mainly to their lower initial organic sulfur contents.
