Transformation of seismic velocity data to extract porosity and saturation values for rocks
For wave propagation at low frequencies in a porous medium, the Gassmann-Domenico relations are well-established for homogeneous partial saturation by a liquid. They provide the correct relations for seismic velocities in terms of constituent bulk and shear moduli, solid and fluid densities, porosity and saturation. It has not been possible, however, to invert these relations easily to determin...
متن کاملOxygen Saturation: A Guide to Laboratory Assessment
measured spectrophotometrically. (To avoid further confusion, I will use only O2sat and SO2 for the remainder of this article.) CO-oximetry, a more complex and reliable method, measures the concentration of hemoglobin derivatives in the blood, the results of which are then used to calculate various parameters such as hemoglobin derivative fractions (e.g., FO2Hb), total hemoglobin, and oxygen sa...
متن کاملHuman Oxygenation by Air during Anaesthesia: the Relation of Ventilatory Volume and Arterial Oxygen Saturation.
Ventilation and arterial oxygen saturation have been measured in 18 patients during anaesthesia with ether or halothane carried in air. All patients were ventilated artificially with a Jefferson ventilator at a frequency of 16 breaths per minute and variable tidal volume. Ventilation has been expressed as a percentage of Radford's standard, Nunn's standard and the patient's pre-operative restin...
متن کاملExtended Longitudinal Scaling: direct evidence of saturation*
Multiparticle production of charged particles at high energies exhibit the phenomenon of Limiting Fragmentation. Furthermore, the region in rapidity over which the production of particles appears to be independent of energy, increases with energy. It is argued that this phenomenon, known as Extended Longitudinal Scaling, is a direct manifestation of some kind of saturation, akin to that in the ...
متن کاملCut Admissibility by Saturation
Deduction modulo is a framework in which theories are integrated into proof systems such as natural deduction or sequent calculus by presenting them using rewriting rules. When only terms are rewritten, cut admissibility in those systems is equivalent to the confluence of the rewriting system, as shown by Dowek, RTA 2003, LNCS 2706. This is no longer true when considering rewriting rules involv...
