Stem loading caused micromotion between the stem and cement.
Sub-fossil wood was collected as stem disks from trunks deposited on the bottom of the lake, all of which originated from trees growing on the nearby hills.
The interpretation of observations of sucrose uptake in stem disks (portions of culm cross-sections) from solution presents additional challenges.
Previous studies to determine the metabolic path of sucrose have often involved application of the tracer sucrose to slices of culm tissue (stem disks).
"We actually saw collagen fibers run between the new disk and neighboring vertebrae".
An adhesion layer of chromium was deposited between the metal disk and the silicon.
The stem consists of limy disks, and the body has an internal skeleton of close-fitting limy plates.
"Cut the semi-wood, between the woody stem and the herbaceous," or soft stem, he said.
Instead a circumbinary disk may form that gives rise to a tidal torque between the disk and the binary.
At the very base of the stem is a small, white, and hairy disk-like base that attaches to the substrate.
