(20) Still, they gave valuable information in relation to environmental screening; thus, the finding of c-mitosis may indicate risks of aneuploidy.
Osmosis
Definition:
(n.) Osmose.
Example Sentences:
(1) CDI and reverse osmosis (RO) equipment can form the key elements of water treatment trains that produce ultrapure water, without the need for the chemical regenerants associated with batch ion-exchange processes.
(2) At 10(-6)M amphotericin B, the DC membrane resistance fell from approximately 10(8) to approximately 10(2) ohm-cm(2), and the membranes became Cl(-)-, rather than Na(+)-selective; the permeability coefficients for hydrophilic nonelectrolytes increased in inverse relationship to solute size, and the rate of water flow during osmosis increased 30-fold.

(6) The reverse osmosis water is the main contamination source for the bicarbonate dialysate, the application of which within 6 hours seems worth being used on account of the low germ count.
(7) They induce volume flows across different pathways, e.g., osmosis predominantly across the cellular route and pressure filtration predominantly across paracellular routes.
(8) Hence non-linear osmosis in rabbit gall-bladder is due to a decrease in water permeability with increasing osmolarity.6.
(9) A brilliant sequence to this simple idea followed through Poynting, Arrhenius, Noyes and culminated with Hulett, who in 1901 formulated the "solvent tension theory" of osmosis, stating in essence that the thermal motion of the solute molecules by impact with the free solvent surface put the solvent under tension.
