The study also revealed a correlation between pubis length and body mass, and an equation for body mass estimation using pubis length was accurate in a dummy sample, suggesting that pubis length can also be used to acquire reliable body mass estimates.
The NMR tube was sealed with a rubber septum and purged with nitrogen gas for 30 min. An initial NMR was taken at room temperature, then the probe was heated to 70 °C, locked, and shimmed on a dummy sample before the insertion of the sample tube.
Triplicate measurements of insoluble solids fraction were performed, using standard NREL analytical procedures, on the initial dummy flask sample and duplicate measurements at the final sample point [ 35].
Some imaginative methods for detecting heterogeneity are now being utilized that include interaction terms, regression trees, robust estimation, dummy variables, and sample splits.
In the initial additive models for both pollutants, the smooth function of spatial location, f s(s), was statistically significant (Tables 2, 3), and the dummy variables for sampling day were mostly significant (data not shown).
With our initial additive model (Equation 1), we accounted for the temporal variability only by using time-varying meteorological and source covariates and a dummy variable for sampling day.
The brains were slowly implanted with the samples: Pt/Ir dummy probes (diameter 100 μm, uninsulated) as the control group and the composite CP-deposited Pt/Ir dummy probes as the testing group.
The advantage of the TFEM is its ability to absorb unobserved heterogeneity without time variations by setting dummy variables for individual samples.
To produce an n-type region, the phosphorus-doped SOD solution (P509; Filmtronics Inc., Butler, PA, USA) was spin-coated onto a dummy wafer, and the sample was loaded in a conventional quartz-tube furnace at 1,050°C for 5 min, while the target samples were kept at a closely spaced distance.
