At least, that's what the guests at the back of the room thought they heard him say, which provoked perplexed mutterings and wary smiles until it was ascertained, from a listener with keener hearing, that what Hertog had actually said is that the books are almost all long.
It was ascertained from the application of void rate models in the hydro-thermal investigation of an underground coal fire that the correlation between heat production and ground surface temperature presents a linear function, while that between outflow velocity and fire source temperature has a negative-exponential-power relationship.
It was ascertained from the focus groups that the survey took about 10 minutes to complete.
Although the use of a twin sample is unusual, it was ascertained from a rigorously defined population with a parallel non-twin comparison group.
The level of threat is ascertained from the veracity of the groups.
One might normally expect a higher loss rate for D than I as it requires a longer follow-up period, however, it may be easier to obtain the former, particularly if it can be ascertained from medical records (for example, death), in which case a lower attrition rate on D may be a plausible assumption.
In the nature of things, it cannot be ascertained from the record whether the railroad company now exacts the rates complained of as being discriminatory and which it was the purpose of the suit to correct; but if it does, of course the power to question the legality of such rates by a suit in equity, brought like the one now here, clearly exists.
It can be ascertained from Table 2 and Figure 6 that the proposed method achieves the best performance among all the methods considered in this work.
Finally, it can be ascertained from the lack of a comparator group and the retrospective nature of the study design that biases could have been introduced when collecting data.
It cannot be ascertained from this study whether using alternative revision stems would achieve satisfactory results, although other stem designs have been used with success in published series of cement-in-cement revision hip replacement (Lieberman et al. 1993, Goto et al. 2008).
