Abstract The presented work summarizes the relationships between stability results and separation theorems. We prove equivalence different types of theorems on by an additive map concerning Cauchy functional equation.

We examine the dynamical destruction of binary systems in star clusters of different densities. We find that at high densities (10 − 10 M⊙ pc ) almost all binaries with separations > 10 AU are destroyed after a few crossing times. At low densities (O(102)M⊙ pc ) many binaries with separations > 10 AU are destroyed, and no binaries with separations > 10 AU survive after a few crossing times. The...
The use of CE in the analysis of pharmaceuticals is now becoming Rrmly established as a useful complement and alternative to the more widely employed technique of HPLC. The major attractions of CE are that considerable cost and time savings are possible, especially in the areas of chiral analysis and in the determination of solutes having limited or no chromophore. The recent advent of the use ...
One way of improving the resolution of particles by size is to minimize the difference in RCF between the top and bottom of the sample. Practically this is achieved by layering the sample as a narrow band over a continuous density gradient. This is called rate-zonal gradient (sedimentation velocity) centrifugation; the conditions are chosen such that ρρ always remains greater than ρl. In a cont...
October 23-27, 2011 Gatlinburg, TN page 8 of 45 17th Symposium on Separation Science and Technology for Energy Applications agents for human applications are being developed. Toward this goal, we are testing in vivo efficacy of Cuprimine and Syprine therapeutics, that are approved by the U.S. FDA to treat copper overload in Wilson Disease (a genetic defect in copper metabolism and transport), f...
