Synthesis and Determination of Partition Coefficients of Zinc Complexes with Clinical Potential application
Zinc sulphate is currently used for treatment of zinc deficiency. Its uptake by the body is poor, necessitating the administration of high doses. This leads to a range of unpleasant side effects. In order to increase the bioavailability of zinc, several zinc complexes have been designed and synthesized using bidentate ligands of hydroxypyranones and hydroxypyridinones. Elemental analysis in eac...
متن کاملLiquid/air partition coefficients of four terpenes.
The liquid/air partition coefficients of four common terpenes, alpha-pinene, beta-pinene, 3-carene, and limonene, have been determined in vitro using head space technique. The liquids used were water, human blood, and olive oil. alpha-Pinene, beta-pinene, and 3-carene were practically insoluble in water and limonene was slightly soluble; all were readily dissolved in olive oil. The oil/air part...
متن کاملStabilization of Coefficients for Partition Polynomials
We find that a wide variety of families of partition statistics stabilize in a fashion similar to pk(n), the number of partitions of n with k parts, which satisfies pk(n) = pk+1(n+1), k n/2. We bound the regions of stabilization, discuss variants on the phenomenon, and give the limiting sequence in many cases as the coe cients of a single-variable generating function. Examples include many stat...

متن کاملSIEVED PARTITION FUNCTIONS AND a-BINOMIAL COEFFICIENTS
The ^-binomial coefficient is a polynomial in q . Given an integer t and a residue class r modulo ;, a sieved ^-binomial coefficient is the sum of those terms whose exponents are congruent to r modulo /. In this paper explicit polynomial identities in q are given for sieved ij-binomial coefficients. As a limiting case, generating functions for the sieved partition function are found as multidim...
