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.
Facultative pigmentation before the infants' first summer, as measured by apparent concentration of melanin, was negligible, but increased significantly from May 2006 to September 2006 (P < 0.05) (Figure).
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.
The primary focus of the redeployment process, which saw the removal of ships from overseas stations and the apparent concentration of forces in British waters, was not the German threat but the need to employ manpower more efficiently; perhaps, also, by retaining ships in home waters rather than keeping them semipermanently overseas it would improve the quality of life of the ships' companies.
The failure of activist government to get that escalator moving again, together with its apparent concentration on the problems or rights of others (minorities, the poor, gays, even criminals)," has resulted in a widespread "sour and skeptical attitude toward government." The improved economy of recent years has taken the edge off that skeptical attitude, write Rogers and Teixeira, giving the two major political parties an opportunity to win "the long-term loyalty of these voters and thus to grasp and keep political dominance."
The apparent concentration of activity prompted some viewers to consider this a confirmed minor shower.
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.
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, 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.
