It is impossible to put a timescale on this".
The researchers say it is impossible to put a timescale on when this might be achieved.
Certainly if it is not done in March it would become impossible because of the timescales provided for in the bill".
There are theoretical reasons to believe that such evolutionary changes may be slow and, within practical timescales, even impossible to reverse (Law and Grey 1989; Dunlop et al. 2009).
Whilst, given the absence of detailed longitudinal data, it is impossible to precisely define the timescale of the transient impact of any intervention, our results suggest that these timescales will be in the order of many years to decades.
"You might be right, the timescale might be impossible," he says.
Since currently, climate models exhibit no skill at decadal timescales, it is impossible to assert that these data can give rise to projections of tsetse distribution.
Among the options on the table for the IOC will be a complete ban on Russia from the Rio Olympics, which begin next month, as well as a proposal to allow individual sporting federations to decide whether to implement separate bans – which, given the timescale, will be almost impossible to push through.
And it's dangerous, more generally, to predict future results by past performance: view things on a sufficiently long timescale, and it becomes impossible to tell whether the progress the New Optimists celebrate is evidence of history's steady upward trajectory, or just a blip.
Within the available timescale, it was found impossible to blind each operator to the other operator's markings.
