The phrase "timeframe within which" is correct and usable in written English.
You can use it to denote a period within which something must be completed or to describe the length of time something may take to be done. For example, "Project managers must provide a timeframe within which the project must be completed."
The durations of the intervening pauses were also analysed, exposing a hitherto unobserved 10-second timeframe within which both GP and patient showed a preference for the conversation to be resumed.
They argue it is far more sensible to hold informal talks with Brussels, and other member states, in order to arrive at the outline of a possible settlement before locking Britain into the strict two-year timeframe within which article 50 negotiations must be concluded (and if they are not, Britain risks having to leave the EU with no deal at all).
The next logical step is to connect the ecological model presented here (predicting litter size as a function of on-shore arrival date) with climate and sea ice models (predicting future break-up, and thus11 polar bear on-shore arrival dates) to obtain predictions for the timeframe within which litter size declines are to be expected.
In addition, most likely the timeframe within which the traveler requests information is quite tight (during travelling).
Sources say the decision is solely down to chairman Ron Dennis and there is no specific timeframe within which it will be made.
In light of this uncertainty, the goals of this investigation were to infer, using nuclear-encoded SSU rRNA sequences, the timeframe within which the major lineages of heterokont algae originated and diversified, and to assess the validity of putative Proterozoic xanthophyte/phaeophyte fossils in the context of the reconstructed time-calibrated phylogeny.
The nuclear-encoded SSU rRNA was chosen as the molecular marker for inferring phylogenetic relationships among the major ochrophyte lineages and the timeframes within which the photosynthetic heterokonts originated and diversified.
In particular, the often short timeframes within which outline applications have to be developed and PPI contributors identified, and the lack of funding to support this work prior to the grant award, are major obstacles to enhancing PPI at an early stage in trial development.
Furthermore, cancer registries do not routinely collect full information on the source of stage data, such as the TNM version used, the timeframe after diagnosis within which stage was recorded, whether it was defined clinically or pathologically, and whether tumour size was recorded before or after neo-adjuvant therapy.
However because the rate is low and applies to the minority of the cells without the predominant alleles, this does not significantly affect the results within the timeframe to which the simulation applies.
This usually occurred within a few months of the conduct of each audit, and within a timeframe which allowed a response to feedback to influence findings of the next audit.
