β¦ Synopsis
It was recently shown that the theories of generic algebraic curves converge to a limit theory as their degrees go to inΓΏnity. In this paper we give quantitative versions of this result and other similar results. In particular, we show that generic curves of degree higher than 2 2r cannot be distinguished by a ΓΏrst-order formula of quantiΓΏer rank r. A decision algorithm for the limit theory then follows easily. We also show that in this theory all formulas are equivalent to boolean combinations of existential formulas, and give a quantitative version of this result.

## Abstract It is shown that one of the two conjugate solutions compatible with the AB part of an ABX system can easily be eliminated, at an early stage of the analysis, by considering intensity ratios in the X region.
An algorithm is developed for the computation of the plasma concentration time curve for a drug administration regime involving fast injection (bolus) and/or continuous infusion. The effect of the pharmacokinetic model parameter variations on the plasma concentration time curve is analyzed and effic
