In addition to the large drop in apparent concentration near [DELTA]n [approximately equal to] 0, there were smaller variations in concentration with refractive index at larger values of [absolute value of [DELTA]n], with an overall trend in particle concentration increasing with higher refractive index.
These assays were then used to quantify and compare different fragments of NT-proBNP in HF patients' plasma and to identify the antibody pair that gave the highest apparent concentration of NT-proBNP in circulation.
Therefore, the apparent concentration of entanglements is decreased as shear rates are increased, and since the time required to form an entanglement is proportional to the viscosity at a given shear rate, the apparent viscosity is also lowered.
What puzzles me is the apparent concentration of attention on the Swiss to the exclusion of all those other countries that have done the same things that the Swiss have, and which are not receiving even a fraction of the attention the Swiss are.
The finding also provides additional confirmation that the solar system, the Milky Way and its galactic neighbors are all moving at a significant velocity toward an apparent concentration of mass -- a velocity above and beyond that resulting from the expansion of the universe.
Therefore, values for the apparent concentration should be consistent across genomic regions.
The contamination of the plasma sample by maternal cells or cell remnants would, however, affect the apparent concentration of maternal DNA in the sample.
The extent of cross-reactivity was calculated from the slope of the linear regression analysis obtained by comparing the concentration of EGFr with the apparent concentration of HER-2/neu obtained in the Bayer Immuno 1 assay.
Diazepam and midazolam would increase the apparent concentration of encainide, the internal standard used in the assay for delavirdine, indinavir, nelfinavir, ritonavir, and saquinavir.
In contrast, when the same set of samples were analyzed with the ACCESS assay, a steady decrease of the apparent concentration was observed (Fig.
When female sera (n = 22) devoid of PSA immunoreactivity were analyzed by the IFMA for PSA-API, the apparent concentration of PSA-API was 0.
