The phrase "absolute time frame" is correct and usable in written English.
It can be used when discussing a specific, unchanging period during which an event occurs or is expected to occur.
Example: "The project must be completed within an absolute time frame to meet the client's deadline."
Alternatives: "fixed time period" or "definite time span."
Although indispensable in providing an absolute time frame at Olduvai, the average 15,000 20,000 year intervals between successive tuff units lack the time resolution to construct a sufficiently contemporary paleolandscape within sedimentary intervals away from the interleaved tuffs.
Despite its smaller size and propensity to adhere to the coverglass surface, we were able to position it readily next to a RAW mouse macrophage cell in order to analyze the absolute time frame of phagocytosis with this particular cell line and pathogen (Fig. 4 and Video S4).
However, fossil information is available and was used in order to calibrate trees in an absolute time frame.
Our study provides an absolute time frame for these two asymmetric build-ups of animal/plant assemblages (asymmetric because each assemblage has many more plant than bird species).
Finally, if there was more than one data set of electrolytes that fitted around the index ABG, the data set with an absolute time frame closest to the indexed ABG was used.
This study provides absolute time frames for the build-up of hummingbird/plant mutualisms in North America and temperate South America, and these time frames turn out to differ greatly.
However, given that respondents could not conceptualise absolute TTO and the time frame being given up was in the order of days to weeks rather than years, we have presented this value as the number of weeks given up rather than as a utility.
Each permit request was individually determined, but no place and no time frame was ever absolute or guaranteed for public assembly.
Classic TTO values most resembled those of the lag-time TTO in a 20-year time frame in terms of mean absolute difference.
Single photon counting electronics (SPC-150, Becker & Hickl, Berlin, Germany) independently recorded the detected photons of both detectors with an absolute temporal resolution of two picoseconds on a common time frame.
In our single-center retrospective study we did not find any association between the absolute time spent in the ED and ICU mortality, and we cannot recommend any clinically relevant specific time frame.
