Sentence examples for concentration variance from inspiring English sources
A method to evaluate the decay of concentration variance in turbulent mixers is presented.
Mixing here is characterized by the scalar dissipation rate, which measures the destruction of concentration variance.
The normalized total concentration variance within the flux is found to be a non-monotonic function of the discharge ratio with a maximum concentration variance at intermediate values of the discharge ratio.
Two models for the scalar dissipation rate, required to close the transport equation for concentration variance, are investigated.
Systems with shorter-range correlation and/or smaller concentration variance require more particles, potentially limiting the computational feasibility of the method.
Micromixing parameters for a given model are determined by equating the predicted and measured values of the time response of the tracer concentration variance.
By analyzing concentration variances of >600 metabolites during differentiation on the stiff and rigid gels (and focusing on chondrogenesis and osteogenesis as regenerative targets, respectively), we identified that specific lipids (lysophosphatidic acid and cholesterol sulfate, respectively), were significantly depleted.
Concentration of reactants, in the investigated range, did not influence mean size of particles, while significant changes of variance were observed: passing from 0.25 to 1 M concentration, variances of particle size increased for w = 5 and for w = 6.25, while decreased for w = 7.5.
Following separation, molecules that often exhibit wide concentration variances in mixtures can be investigated by combined NMR/MS, with acquisition parameters specifically adapted to maintain the optimum dynamic range necessary for good quality spectra.
Database fields include information on sediment and biota samples (e.g., collection location and dates; sediment depth analyzed; average concentrations, variances, and number of samples for sediment and biota; organism lipid and sediment organic carbon content).
Only one minor repeated QTL for a berry acidity trait was detected twice in Picovine, at the top of LG 5, explaining 6%to12%12 % of the total berry acid concentration (ToAG) variance at green lag phase.
