The rectangular duct used had aspect ratio of 12 and the Reynolds number based upon the mass flow rate of air at inlet of the duct ranged from 4000 to 12,000.
In contrast, for cases classified as showing minor duct involvement, the mean diameter of the largest involved duct was only 0.08 cm (median=0.05 cm), with the largest involved duct ranging from 0.26 to 0.01 cm.
For cases classified as prominent intrabiliary growth, mean diameter of the largest involved duct was 0.63 cm (median=0.55 cm), with the largest involved duct ranging from 2.0 to 0.1 cm; cases at the lower end exhibited multifocal ductal involvement.
Regarding geometric characteristics of air ducts, most common rectangular air ducts range from 100 mm × 200 mm to 150 mm × 300 mm and circular ducts, from Ø100 to Ø200 mm in households.
Ramsay et al. [ 5] identified a mean number of 9 milk ducts (range 4 18) in each lactating breast using ultrasound imaging.
BAFF was positive in all but one cases of cancer, with an H-score ranging from 30 288 (mean = 145, median 147), in all cases of DCIS (mean H-score = 163, median 184, range 44 200), in all assayed cases of ducts (range 145 300) and in all three assayed cases of normal lobules (H-score range 140 200).
ELAs of supply ducts ranged from 0.4 to 2.0 cm2 per square meter of floor area served, and from 1.0 to 4.8 cm2 per square meter of duct surface area.
The coelozoic plasmodia in bile ducts ranged from 4 25 µm in diameter, had numerous mitochondria, pinocytic channels and dispersed lipid inclusions in the cytoplasm (Figure 2D).
The size of disruptions varied substantially among ducts, ranging from the combined size of three to more than 30 myoepithelial cells.
Bile duct injuries range from very minor accessory duct injuries to complicated hilar injuries, and Strasberg et al. categorized laparoscopic injuries to the biliary tract with a system known as the Strasberg-Bismuth classification [10].
