For example, C stock estimates for standing live tree biomass are based on inventory tree data, whereas estimates for down dead wood, litter, and soil organic matter are generated from models based on geographic area, forest type, and in some cases, stand age [2 4].
Carbon estimates for the ecosystem components of forest floor (inclusive of litter, fine woody debris, and humic soil horizons), down dead wood, belowground (BG) biomass, and soil organic matter are calculated by FIA using models based on geographic area, forest type, and, in some cases, stand age [6, 8].
NEDS utilizes a stratified sampling strategy based on geographic area, urban/rural area, ownership (i.e., government, private, not-for-profit), trauma center and teaching status, and bed size (Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project (HCUP) 2016).
Four family practice clinics were recruited to participate based on geographic area, clinic interest, and past experience with other ORPRN projects.
The sampling design for each state was stratified, based on geographic area or population densities and types (e.g., urban, rural, frontier, reservation).
The sample size of 750 adult women age 20-400) years was based on geographic area and population size representativeness, excluding the Milan region which had already been represented in the magazine survey.
In these methods, the network simplification is based on geographic areas or control areas that only cross-regional transmission lines would be tripped after the power system lost its synchronization.
A three-stage probability design based on geographic areas, hospitals, and discharges is utilized to select sample data.
The 16 teosinte accessions were chosen based on geographic criteria to represent all areas where Z. mays ssp.
There are 60 physical therapy practices in five areas within the county council, which were allocated to intervention (three areas, 28 practices) or control group (two adjacent areas, 32 practices) based on geographic location.
In production environments, one possibility for a finer-grained set of publications could be a definition based on geographic regions (e.g. "Airspaces in the San Francisco area").
