Swimming may help white rockfish juveniles maintain stable NND under lowest light intensity (0.1 lx in this study) by providing motion cues to the lateral-line sensors of the fish: by contrast, they likely are able to maintain NND under intermediate light conditions (e.g., 1-10 lx) by using their vision.
The NND and SA have been referred to as indices of the density of individual fish and the orderliness of a fish school (Masuda, 2006; Miyazaki et al., 2000).
It has been suggested that development of mechanosensory organs, such as lateral lines, contribute to decreases in NND in school formations of juvenile fish (Masuda and Tsukamoto, 1998).
Further analyses were performed on a subset of physicians most likely to provide outpatient medical care to children with NND conditions: primary-care pediatricians, neurologists, geneticists, developmental pediatricians, and physiatrists.
Although they are at greater risk for poor outcomes related to infection with influenza viruses, influenza vaccination of children with NND conditions was similar to that observed in the general pediatric population.
Despite these limitations, the results of these surveys demonstrate that children with NND conditions are no more likely to be vaccinated than healthy children, despite the fact that they are at increased risk for poor outcomes.
There was a higher (p<0.05) pH value in NND compared with the other two N sources (Table 3).
N[O.sub.3.sup.-] and N[O.sub.2.sup.-] were not detected within the microbial cells from the three diets (data not shown), which is presumed to indicate that all N[O.sub.3.sup.-] added to NND was reduced to N[H.sub.3]-N by rumen microorganisms.
Nitrate and nitrite disappeared from the culture fluid of NND by 24 h of incubation (Table 4).
