The phrase "areas differences" is not correct in written English.
It seems to be a typographical error or a misphrasing.
Example: "The areas of differences between the two proposals need to be addressed."
Alternatives: "differences in areas" or "variations across areas".
Since the TMA was constructed to represent two spots of tumour from each case sampled from different tumour areas, differences of immunoreactivity between these spots can be used to estimate intratumoural heterogeneity of expression.
In urban areas, differences of absolute particle number concentrations between different measurement sites can be great (Krudysz et al. 2009), with the largest variations in ultrafine (< 100 nm) and coarse (2,500 10,000 nm) particles and more homogenous spatial distributions of accumulation mode particles (100 2,000 nm) (Monn 2001).
Within such areas, differences in population density are largely a function of water availability (whether directly from rainfall or from irrigation) and soil fertility.
The second is technology, in that in some areas differences of style depend on the material employed.
Within the main areas differences were observed (after correction for confounding) between small local districts.
Collapsing data across all areas, differences were 0.12 ± 0.20 mm and 0.11 ± 0.20 mm for stent and tissue areas, respectively.
The percentage of institutional deliveries varied from 41.2% in rural areas to 75.3% in urban areas (difference of 34 points).
Most of the step-up factor is due to area differences (eardrum vs. oval window)... about 20 times.
Divergent patterns of rural segregation reflect local-area differences in population dynamics, economic inequality, and the county employment base (using Economic Research Service functional specialization codes).
Approximately half this error can be explained by error in the measured variables, the rest being due to real inter-area differences in noise reaction.
Our results suggest that in the study area differences in field shape, height and layout are primarily the result of an adaptation to the local edaphology.
