"It is impossible to demonstrate just as conclusively that screen-based activities are having an unequivocal effect on the brain".
In interviews, administration officials said they had concluded that it would be impossible to demonstrate Mr. Padilla's involvement in the dirty-bomb plot without exposing the harsh methods used to elicit the information from captive Qaeda leaders.
Exercise physiologists say it can be impossible to demonstrate its value because usually too many things change simultaneously when people start to run in groups: the coach, the location, the training regimen.
Your correspondent suspects that it will be impossible to demonstrate whether or not that target has been achieved, if only because no one knows how many species there are on the planet.
"Absence of evidence is not evidence of absence," she observes, "Thus it is impossible to demonstrate definitively that screen-based activities have no effect at all on the brain or behaviour, any more than I or anyone could prove definitively, to use an age-old example," here it comes, "that there is not a teapot in orbit around Mars".
The challenge was that it was impossible to demonstrate the working software in a prototype form.
Leibniz argued that, since perfections are unanalysable, it is impossible to demonstrate that perfections are incompatible and he concluded from this that all perfections can co-exist together in a single entity.
This indirectly validates the estimation of EVLWI by transpulmonary thermodilution since such a prediction of mortality would be impossible to demonstrate if the measurement of EVLWI were not valid.
Although it is impossible to demonstrate the effectiveness of species action planning through rigorous scientific assessment, these results indicate a substantial amount of conservation-relevant activity directly attributable to the process.
When a system assures a function by no means connected to the safety, it is of SIL level 0. The SIL's notion is particularly useful for computer systems, notably software, for which it is impossible to demonstrate the respect of an objective calculated for safety.
