The temperature gradient alone causes a density gradient that decreases with depth.
Perturbations caused by density gradients and winds will be backed out from these measurements.
As neurogenesis occurs, a density gradient of neuronal cells appears in the body.
Such a density gradient may be continuous or prepared in a stepped manner.
The term refers to the movement of water over large distances as a consequence of global oceanic density gradients.
The blood was separated by density gradient, which left a population of cells enriched in lymphocytes and monocytes.
The caesium chloride molecules sink to the bottom of the test tubes creating a density gradient.
"Yes, due to the refraction effect from the density gradient of the thick atmosphere," Percy said.
The role of the density gradient depends on its sign.
As a general rule, establishing density gradients between miscible substances is very tricky, because they are inherently unstable.
