On the other hand, existing approaches for the delineation are based either on a single indicator that may not be adequate to reflect several aspects of groundwater development or on too many indicators, data of which may not readily available for a target area.
This subfamily was not monophyletic, but its delineation was based on results from probabilistic homology searches using peptide sequences, detailed below.
The period delineations were based on the timing of major disturbance events and expected and observed trends in coral cover in the Indo-Pacific.
Studies from Taiwan up to the 1980s described groundwater levels of up to 300 ppb as low, of up to 600 ppb as moderate, and values beyond that as high., These delineations were based on a view that consuming arsenic in groundwater, while harmful, wasn't fatal in the long run.
As the original developmental stage delineations are based on major morphological events in the fruit fly development, it is, in principle, possible to distinguish embryos in images at the level of individual stages (Ji et al., 2008; Ye et al., 2006, 2008).
In actual astronomical practice, the delineation of the galactic quadrants is based upon the galactic coordinate system, which places the Sun as the pole of the mapping system.
The delineation of kosher vs. non-kosher is based either on required characteristics (simanim), a list of permitted or prohibited animals, or both.
Common clinical practice is based on manual delineation and fixed or iterative threshold methods, the latter of which requires regression curves dependent on many parameters.
The method to determine the input function is based on the delineation of an ROI on the 18F-FDG scan images and using this ROI on images obtained from a dynamic scan with 11C-dLop.
