For example, Arkansas carried out a technologically ambitious program, placing multi-sensor gas monitors on five-foot tripods along each perimeter of a well pad at several sites.
Receiver, for instance, is situated in quadrant II, so it is included in a receiver pair with each perimeter receiver in. Figure 1 Example of perimeter receivers.
We selected a total of six biologically informative summary statistics that collectively capture the size, position and permeability of candidate barriers: area, perimeter, maximum latitudinal range (controlling for longitude, max latitude minus min latitude), mean distance from equator (based on the absolute value of the centroid of each barrier), perimeter-to-area ratio, and fragmentation.
The species richness and abundance of all flowering plants in bloom at each site were recorded using a quadrate method with 1 x 1 m quadrates placed every meter along each side of the perimeter of each hexagon, creating 20 quadrates along the outer perimeter of each side and 19 along the inner row (234 quadrates in total for each recording).
Capillary perimeter: perimeter of each individual capillary was computed by estimating total number of boundary pixels surrounding the capillary region.
(vii) Capillary perimeter: perimeter of each individual capillary was computed by estimating total number of boundary pixels surrounding the capillary region.
Figure 7b shows the mean length of the perimeter of each cell associated with this type of contact.
Five representative microphotographs of the labyrinth were taken from each placenta at 60x and six measures of optical density (each with a perimeter of 5 μm) were performed for each sample (n = 300).
The perimeter of each spot was delineated and pixels exterior to this perimeter were excluded from subsequent analyses.
The cavity area was calculated as a percentage of spinal cord area (i.e. area within the tracing of spinal cord perimeter) for each section.
The area and perimeter of each nanoparticle was extracted before calculating circularity 4 π Area Perimete r 2 and diameter 2 Area π, estimating particles to be spherical.
