The phrase "a reasonable approximation as" is correct and usable in written English.
It can be used when discussing a value or estimate that is close enough to be considered acceptable in a given context.
Example: "The calculated value serves as a reasonable approximation as it closely aligns with the observed data."
Alternatives: "a fair estimate as" or "a close representation as".
This is a reasonable approximation, as molecular binding models describing the interactions between transcription factors and DNA have shown that binding energies are approximately additive between bases [9] (in other words, interaction of binding specificity is negligible).
We believe, however, that using the aperture size is a reasonable approximation as we achieve reproducible, quantitative charge flux values.
This has been determined to be a reasonable approximation, as this value is unable to be non-invasively obtained and Sunagawa et al. (1983) have reported that the actual value is negligible compared to ESV and EDV.
While a ratio of the SMRs or SMbRs is not correct, it should be a reasonable approximation as the age and sex distributions of the two embassy groups do not vary greatly, and so have been added here in Tables 2 and 3.
Here we treated each fast B-scan as a rigid body (assume no motion artifacts), a reasonable approximation as each was collected in just 1.3 ms. Finally, the photoreceptor layer and retinal pigment epithelium (PL-RPE) complex was extracted from the axially registered volumes and en face projections generated.
This proportionality assumption does not have to be true, as long as it is a reasonable approximation – but of course, as we are dealing with unknowns the approach also has the advantage of simplicity.
In addition, for stover, a serial twofold dilution series Dot blot estimated the E1cd content of E1-1 to be approximately 3 ng/mg biomass (data not shown), which was a reasonable approximation for the Western blot analysis as well.
This projection greatly deforms Earth's actual surface, but gives a reasonable approximation for the distance between two points as long as those points are closer than about 100 km and not near the poles.
Although expression arrays are the 'gold standard' for defining these subtypes, there is sufficient evidence to suggest that the markers we selected provide a reasonable approximation of molecular phenotypes, as determined by gene expression profiling.
As a reasonable approximation, we consider that the linker behaves like a polymer coil, acting as an "entropic" spring [38].
In a lifetime, the island in the south of the Gulf of Thailand has been transformed, and has come to be seen as a reasonable approximation to paradise by the thousands of Western backpackers who converge on it each year.
