Even materials with nominally similar specifications can vary in their in-service performance owing to different source of raw materials, in the case of refractories, and different heat treatment processes in the case of sophisticated high performance alloys.
Among the 1000 random permutations of group assignment (i.e., under the null hypothesis), the number of nominally significant tests varied between 0 and 25 out of 105.
Within each group of isomers, such as the nona-BDEs and octa-BDEs, the estimated apparent half-lives varied nominally, albeit with wide and overlapping confidence intervals.
We must mention that the residual resistance obtained for nominally the same compositions may vary significantly for different groups of compounds.
Circuits using graded signals or action potentials share these issues because the small number of vesicles associated with transmission of physiological signals cause synaptic release to vary even for nominally fixed presynaptic signals such as action potentials (Del Castillo and Katz, 1954; Allen and Stevens, 1994).
The latter finding is consistent with previous reports which have shown that at relatively close range the blast pressure due to nominally similar charges and standoff distance can vary significantly, thus producing different levels of damage.
But results also vary in some countries (like Japan) with nominally comprehensive systems.
Cross-sections of nominally similar geometries, but from the two different production routes may vary significantly in terms of their general material properties, geometric imperfections, residual stresses, corner geometry and material response and general structural behaviour and load-carrying capacity.
Overall, approximately 15% of the differentially expressed genes are coral specific (no match to database sequences at < 1 × e-5), but the relative proportion of these nominally taxon-specific genes varies widely between the synexpression clusters.
While actual numbers are likely to vary substantially from year to year based on the dynamics of viral outbreaks in Asia, these studies nominally suggest that between 1540 and 18 200 (based on estimated population sizes) infected Dunlin could be in Alaska in any given year.
The offences vary widely – from flouting international rules designed to protect fragile stocks in the northern hemisphere, to the trawling of nominally protected but barely policed waters in some parts of the south.
