Overall, when this fast preparation of pure RNA was coupled to crystallization assays for which we used the free interface diffusion system, the time span between RNA molecule design and in-chip crystal observation was under two weeks.
Second, for examining free-living activity, we used a time span of 9 00 16 30 in which 'occupational activity' was mostly measured.
Progression-free survival will be determined as the time span between start of the treatment and tumor progression or death, whatever occurred first or an event which characterises a censored observation.
Though just a free app, 1 million downloads in such a short time span is extremely impressive.
Free-fall is also found when using sounding rockets, which provide r- μg during a time span of up to 15 minutes.
The new cell design allows pseudo equilibrium to be reached for the free metal ions via a Donnan equilibrium across a negatively charged ion-exchange membrane within a reasonable time span.
The time span is significant.
Here, somehow, the time span feels short.
The time span is 150 years.
