Bricks are geographical blocks used to break down countries and cities into meaningful units for analysing sales of drugs.
However, direct comparisons cannot be made, since the latter emitted higher dioxin levels and has been studied at a finer geographical level (blocks), with a different (case-control) design.
M. sieversii accessions in Kazakhstan showed admixed ancestry possibly from hybridizations with wild apples such as M. orientalis along the Silk Road, and/or domesticated apples cultivated nearby, while Xinjiang accessions kept their homogeneous genetic background probably due to their geographical isolation that blocks interspecific hybridization.
Usually, cluster sampling involves selecting participants only from a limited number of defined geographical areas (eg, blocks, streets or parts of villages, or perhaps schools) that are themselves chosen randomly.
"Analysis of these flows suggests that the first transfer, due to its amount and its geographical origin, could be blocked in France in application of anti-money laundering rules," according to the documents.
Many studies employed some form of cluster sampling, usually selecting participants from a limited number of defined geographical areas (e.g., blocks or streets, or parts of villages), themselves chosen randomly.
Per district, two blocks or geographical units were selected.
Sexual networks do not strictly follow geographical boundaries and the blocks for implementation were not contiguous.
These should contain geographical features such as: blocks, plots, constructions, water accumulations, relief and vegetation, and they should be used jointly with geodesic coordinates which could be provided by the global positioning system (GPS) and spatial statistical software [ 12].
As in most relatively higher R0 populations, we observed for the first OPV restart iteration that even a very large number of oSIAs with IPV with a block-wide geographical scope and increasingly wide target age range could not control the outbreak.
