The number of paint samples that can be aged at the same time is restricted to 30 samples for practical reasons: the gloss meter requires a specific area for analysis (2.5 by 7.5 cm) and the size of the aging chamber is about 30 times that area (46 by 32 cm).
Already, some ecologists used a barcoding approach to identify a specific unknown plant sample for practical purposes [11], [47], [48].
Urine was collected as a spot sample for practical reasons, though the interpretation of urinary creatinine levels used for the correction to ≥24 hour urine output may be problematic.
The sensor successfully estimates the H2O2 concentration in the real sample (rainwater) for practical analysis.
Having matching control samples would likely remove cell type-specific findings, but it is often very difficult to obtain such a sample for various practical reasons, such as the limited availability of healthy tissue.
It is completely independent of laboratory facilities and can therefore be performed and evaluated on-site even in populations where blood sampling remains problematic for practical reasons (for example in young children) or on religious grounds.
As the prior volume shrinks more rapidly for lower values of n, and the number of likelihood evaluations reduces accordingly, it is important to establish this feature of nested sampling's configuration for practical applications.
One limitation, common in observational studies taking the present approach, is the limited sample size, because for practical reasons it is difficult to carry out this type of study with a larger group.
The original resolution of the videos were 1,080×1,920 pixels, but we down-sampled them to 270×480 for practical purposes.
For practical reasons, we sampled only in South Africa and samples of genera occurring outside the borders of South Africa were only collected if the relevant representative tree species were found in one of the National Botanical Gardens.
