The term refers to the movement of water over large distances as a consequence of global oceanic density gradients.
12.
A "'pycnocline "'is the cline or layer where the density gradient ( ) is greatest within a body of water.
13.
The : cancellous bone porosity is within the : trabecula structure, which has a platelet density gradient increasing radially outward.
14.
Examples include colloidal epitaxy and space-based reduced-gravity techniques, as well as the use of temperature gradients to define a density gradient.
15.
These pumps generate flow through a number of different mechanisms including self-diffusiophoresis, electrophoresis, bubble propulsion and the generation of density gradients.
16.
In collaboration with Jean Weigle, Meselson then applied the density gradient method to studies of genetic recombination in the bacteriophage Lambda.
17.
The carriers move in the direction of decreasing concentration, so for electrons a positive current results for a positive density gradient.
18.
These immunorosettes pellet when centrifuged over a density gradient medium, leaving untouched target cells at the plasma : density gradient medium interface.
19.
Below the mixed layer, a stable density gradient ( or pycnocline ) separates the upper and lower water which hinders vertical transport.
20.
They used density gradient centrifugation to determine which isotope or isotopes of nitrogen were present in the DNA after cycles of replication.
