To simulate heterogeneity sections, density structure models are needed.
No evidence of intestinal metaplasia was found, even though all except 4 (3 HIV seropositive, 1 HIV seronegative) had positive serology for H. pylori, and Helicobacter-like organisms were visible in 30 out of the 37 histological sections (density recorded as low in 8, intermediate in 14, and high in 8).
In sections were the total catch was less than 16 individuals (ten out of 25 sections), densities were estimated from average catchability (i.e. estimated catchability from the other sections).
The relationship between absorption cross section, density and refractive index is σN = 2k 0n", where n" is the imaginary part of the refractive index which describes the absorption phenomenon.
In the examined river section, densities of 10 15 animals per m2 were found with a biomass of 53 61 g/m2 over 1 year, while density in optimal areas of the habitat could reach considerably higher numbers [9].
Using 5 to 7 μm thick sections, cell density and lining layer thickness were determined for about 45 sections from at least three different tissue samples per patient (HE stain).
For semiquantitative analyses of immunohistochemically stained tissue sections, the density of AT8 positive tau accumulation was graded to be 0 for absent, 1 for low, 2 for intermediate and 3 for high, based on microscopic observations at ×200 magnification.
These cases exhibited more extensive fibrosis, measured either by the proportion of collagenous tissue within the tissue sections, the density of the collagenous tissue, or the extent of peri-ductal fibrosis.
Oral to the clip, on frozen sections the density of DOG1+ ICC was significantly reduced and the distribution was not continuous compared to the control group, and on the whole-mount preparations, ICC networks were partly damaged, and the numbers of DOG1 and DAPI double-labeled cells were also significantly reduced, indicating that some ICCs might be absent.
This graphical visualisation shows the Pearson's correlation coefficients among each pair of variables (lower section), the density functions of each variable (diagonal) and the regression lines with their corresponding confidence intervals (upper section).
Particular attention is paid to the number of grain-to-grain contacts (packing proximity) and to comparisons between the sum of the lengths of grains to the total length of a traverse across a thin section (packing density).
