Mass Fractionation in Hydrodynamic Escape

We show that mas s fractionation occurs during the course of hydrodynamic escape of gases f rom the a tmosphe re of an inner planet. Light gases escape more readily than heavy gases. The resul tant fract ionat ion as a funct ion of mas s yields a linear or concave downward plot in a graph of logari thm of remaining inventory against a tomic mass . An episode of hydrodynamic escape early in the ...

Cell separation by dielectrophoretic field-flow-fractionation.

Dielectrophoretic field-flow-fractionation (DEP-FFF) was applied to several clinically relevant cell separation problems, including the purging of human breast cancer cells from normal T-lymphocytes and from CD34+ hematopoietic stem cells, the separation of the major leukocyte subpopulations, and the enrichment of leukocytes from blood. Cell separations were achieved in a thin chamber equipped ...

Human plasma derived drugs separation by fractionation of plasma with polyethylene glycol

Background: There are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. There are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. Ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...

Fractionation of Newcastle disease virus by chromatography on diethylaminoethyl cellulose.

Wilson, Dwight E. (Rensselaer Polytechnic Institute, Troy, N.Y.). Fractionation of Newcastle disease virus by chromatography on diethylaminoethyl cellulose. J. Bacteriol. 84:295-301. 1962.-The L. Kansas and NK strains of Newcastle disease virus were chromatographed on diethylaminoethyl (DEAE) cellulose ion-exchange columns. L. Kansas virus eluted from DEAE columns showed one peak of hemagglutin...
