There is a danger that when the bacterial contamination is this stringent, the effect of treatments that produce anything less than a massive effect on bacterial levels will not be detected, leading to a Type II error.
These measures could then be used as tight statistical controls in order to provide stringent tests for the effect of competence assessments.
A serum with a high antibody titre was selected for this stability test; in future EQAs, samples with a titre closer to the limit of detection may be included for a more stringent assessment of the effect of stabilizing reagents on assay sensitivity.
To provide a more stringent test of the effect of CD40 signaling on NGF-promoted neurite growth, we compared the size and complexity of the neurite arbors of SCG neurons obtained from neonatal CD40-deficient mice and wild-type littermates.
More than 500 species were quantified in the 1 1 and 3 1 samples; however, fewer clusters were quantified in the 5 1 sample where the effect of stringent filters employed during lysine prediction limited the number of detected NeuCode SILAC partners.
We saw essentially no effect of effective population size, but slightly higher (less stringent) thresholds for smaller sample sizes.
In this study, we investigated the timing of the stringent response at the histidine and serine biosynthesis genes by real-time RT-PCR and the global effect of the stringent response on gene expression by using comparative DNA microarray hybridizations.
Scholars attribute the decline in applications to several factors, including a wider availability of low-end jobs, new supports like the earned-income tax credit and a deterrent effect of more stringent welfare rules.
A recent study of the effect of more stringent security measures at the US Canadian border (Lipovic et al. 2015) found the flow of American day-trippers to Canada had been reduced by 59%%, while Canadian day trips to the US had been curtailed by 50%%.
As a further stringent test of the selective effect of proNGF in promoting neurite outgrowth from different kinds of NGF-dependent neurons, SCG and trigeminal neurons were separately labelled with different fluorophores and co-cultured in medium containing proNGF.
