In another study in computer science courses with and without PI, students' high school background was compared with scores on a final examination (Simon et al., 2013b).
The emission data were reconstructed following the quantitative method described above, and the mean calculated concentration of radioactivity found in hand-drawn regions of interest (ROIs) over several slices in background was compared with the known amount.
This may be a critical question when laboratories use different colonies to induce other diseases, PGIA or PGIS, or when transgenic/gene-deficient mice in 'different' BALB/c backgrounds are compared with control wild-type BALB/c animals.
Water quality parameters, such as ORP, EC and pH, collected at the background tests were compared with the results from the experiments.
To minimize strain-specific effects, the flies analyzed using the Affymetrix Drosophila 2.0 microarray were, as in the case of tko 25t, an F1 hybrid of sesB that had been backcrossed to Canton S or Oregon R backgrounds, and the results were compared with those of a corresponding control F1.
In same way, the putative gained introns of these two species were mapped to 86 intron-gained genes of Dictyostelium discoideum, which were compared with background sets for GO enrichments.
As there was the often moment-to-moment fluctuation in PVN neuronal excitability that was associated with a change in background activity, the impulse counts in association with a stimulation procedure were compared with the background activity for the 30-second period immediately before the stimulation took place ("net response").
People with white backgrounds were compared against those with other ethnic backgrounds on the basis of demographic characteristics (Table 1).
Another limitation is that there was no comparator group, so proportions of observed outcomes were compared with the available background rates from the general population derived from the literature.
