To reduce subjective variation during gel observation, peaks with an intensity under 60 units were discarded.
We find that the hmF2 observations peak around the pre-sunrise and sunrise hours depending on the month.
In the case of paired tests, the subjects in both groups are the same (or matched pairs) and therefore the mean difference between two repeated observations (peak measurements) is compared (e.g., metabolic response before and after drug treatment).
In August, where the 99th percentile corresponds with 295 observations, peak levels of TSP occurring at the 999th permillile are more than 24.9 times higher than those levels observed at the 990th permillile, while peak levels of PM10 at the 999th permillile are more than 2.5 times higher than those levels observed at the 990th permillile.
In May, where the 99th percentile corresponds with 105 observations, peak levels of TSP occurring at the 999th permillile are more than 3.8 times higher than those levels observed at the 990th permillile, while peak levels of PM10 at the 999th permillile are 6.0 times higher than those levels observed at the 990th permillile.
Additional specimens were located directly above this site on a plateau between South Ridge Peak and Observation Point.
As summarized in "Satellite observation" section, peak-to-peak amplitude of (delta B_{y}) in Fig. 3b, which corresponds to zonal component of magnetic perturbations, is largest.
After the observation of peak ALP levels in ZnOA-coated titanium samples, mineralized bone nodules were observed by scanning electron microscopy.
Observation of peak counts of potentially mobile elements (Na, K, Si) was undertaken to identify an optimal probe diameter of 30 μm for the analyses (i.e., no signal change during the duration of the analysis of these elements, no drop in signal due to beam defocusing).
Perhaps the most important is the observation that peak performance in the recall of a number of behavioral tasks shows a diurnal [9] [12] as well as a circadian variation [13], [14], [15].
Moreover, for the observation of peak splitting and more specific determination of the ELNES, 0.01 eV energy resolutions are needed.
