The surrogate model for brain activity consisted of 15 regional sources covering all brain regions.
Data from lake sediments, peat cores, and ice cores all indicate that atmospheric Hg deposition has increased globally by about a factor of 3 since preindustrial times (∼1850), with larger increases in regions receiving elevated deposition from regional sources.
To compile data on species occurrences, we used the Pan Arctic Flora checklist (Elven et al. 2011) for those of our regions that are included there, otherwise Hultén and Fries (1986), various regional sources and personal observations [see complete taxon list per region in Supporting Information—Table S3 ].
Thus, this method of source apportionment represents an estimate of the maximal amount of Hg contributed by regional sources and may be limited in regions of deep convective mixing.
For example, most study regions will have some pollutant concentrations dominated by regional sources that are likely to remain spatially homogeneous and some pollutant concentrations dominated by local sources that are likely to be spatially heterogeneous within the study area.
Mr. Murray really accomplished something substantial in the 1980's, connecting vanguardist notions with American traditional and regional sources like gospel and rhythm-and-blues, not to mention following a growing interest in the history of jazz qua jazz.
Regional sources told The Independent on Sunday that the executions were ordered as part of the rumoured feud between King Salman and his remaining brothers which has threatened the entire dynasty.
Specific regional sources of contamination can increase PFC levels in foods and drinking water.
The trajectory analysis also indicates important contributions from regional sources of emission.
We've also been able to obtain equity investment from lesser-known regional sources, such as Finance Wales and its angel network, Xenos.
One of the major limitations occurs when local or regional sources of 137Cs contamination mask the pulse from global fallout, making temporal estimates of redistribution difficult or impossible.
