n = number of samples at each study time point.
Figure 16 shows the comparison of oil recoveries for different oil samples at each stage.
Error bars indicate ± 1 standard deviation, four samples at each site, all samples from Demokeya.
Figure 4c shows the surface area ratios of corresponding samples at each condition.
All experiments were conducted at least three times, with three or more samples at each point.
Sample bottles were also rinsed with actual water samples at each bore well before collecting samples.
In other words, we extracted training samples at each pixel location of the training images.
Before soil sample collections, three samples at each depth were collected with volumetric cores for determining bulk density (BD).
To produce a color image there should be at least three color samples at each pixel location.
The transmittance values for the samples at each pH value are normalized by the total transmittance for that pH.
Three beech-dominated sites were selected along an altitudinal gradient and grid sampling was used to collect soil samples at each site.
