Because airflow velocity decreases from 150 cm/s in the upper conducting airways to nearly zero in the peripheral airways, movement of both particles and gases is via mass-action or diffusion within the acinus and is primarily concentration-driven. Particles that deposit and persist in this environment will be dispersed or cleared by surfactant and phagocytic cells.
In chess or checkers, the only occult element is a player's strategy: checkers is won or lost primarily on concentration; chess on skill, brainpower, and aggression.
In fact, Yushchenko's unpopularity comes from his failure to deal with the problems that the Orange revolution targeted: primarily, the concentration of power and money among a venal elite who are immune to prosecution.
It has been reported that YC-1 can induce apoptosis in vitro in cell-lines, but this is primarily at concentration higher than 5 μM, so the reduction that was seen at 1 μM is due to blocking of HIF-1 activity [ 28].
Cluster analyses on genes from these pathways (p53 and cell cycle) demonstrate that genes are correlated primarily by concentration, followed by time, and finally brand, which does not exert a major effect on gene expression, again supporting our conclusion that there are no clear brand-specific effects for the three CSCs examined in the present study.
Our results provide strong statistical evidence favoring two saturable pathways, one operating primarily at concentrations < 1 ppm and the other primarily at concentrations > 1 ppm.
Predicted concentrations in drinking water were used instead of measured concentrations because few studies have measured estrogen concentrations in U.S. drinking water, and those that are available report primarily nondetected concentrations [see Supplemental Material, available online (doi 10.1289/ehp.0900654.S1 via http://dx.doi.org/); see also Hannah et al. 2009].
As for INRs determined by CoaguChek XS, there is no influence of citrate and the clotting time in this device depends primarily on the concentration of clotting factors including the endogenous calcium ion concentration in the blood [ 21].
These modes can reversibly interconvert, with the transitions influenced primarily by salt concentration and type as well as protein binding density on the DNA (Bujalowski and Lohman, 1986).
As noted above, the rare earths are fairly abundant, but their availability is somewhat limited, primarily because their concentration levels in many ores are quite low (less than 5 percent by weight).
The results show that primarily the large concentration of Cr-related point defect in this sample is responsible for the leakage.
