Spencer's attorney, John Blanchard, countered Wednesday that authorities could not recover any fingerprints from the gun, that a DNA sample provided only a possible match to Spencer and that a witness a few feet away from the shots could not identify Spencer in a lineup shortly afterward.
Most women in our sample provided only one or two reasons for their caesarean and where multiple reasons were provided this was often the pairing of a clinical indicator with maternal preference or carer/hospital recommendation.
Moreover, a sample of 496 (or even the 644 available for the entire sample) provides only 95% power to exclude an association that accounts for 2% of the variance.
In addition, smear slides samples provide only semiquantitative information.
Conclusions: The high variability we observed in children's DAP metabolite concentrations suggests that single-day urine samples provide only a brief snapshot of exposure.
Our AA samples provide only 65 and 56%% power for these two SNPs to detect the effect size at a significance level of α = 0.05.
Of note, quantitation of scV/Tc uptake, either from scans or from gamma counting of tissue samples, provides only the 'average' uptake values, and do not reflect significant heterogeneity in VEGFR expression, as detected by immunohistochemical analysis of our samples (Figures 5 and 6).
Since our experiments have been performed with fresh breast tumor samples which provide only limited quantity of cells after disaggregation we were not able to apply alternative test systems such as MTT or XTT assay to validate the outcome.
This cost is higher in fracture and karstic aquifers due to the higher drilling costs and the heterogeneous flow fields typically require more data than are available from discrete sampling techniques which provide only limited two- or three-dimensional data.
A priori sample size calculations usually provide only rough estimates.
Note that all of these evaluations, based as they are on a single sample from each tissue, provide only a qualitative assessment of variation.
