We study tropically planar graphs, which are the graphs that appear in smooth tropical plane curves. We develop necessary conditions for graphs to be tropically planar, and compute the number of tropically planar graphs up to genus $7$. We provide no

Cumulative cultural evolution, the accumulation of sequential changes within a single socially learned behaviour that results in improved function, is prominent in humans and has been documented in experimental studies of captive animals and managed

Although it has long been known that the small bowel pleats itself along the long intestinal decompression tube as it passes downward, no previous studies have been under-taken to demonstrate differences that occur by the use of different lengths of

In an attempt to determine what effect changes in position would have upon the gastroduodenal arterial pressure, the authors constructed of glass tubing a replica of the hepatic artery, the gastroduodenal artery, and the common hepatic artery. These
