A PREDICTION PROBLEM IN L(w)

چکیده
For a nonnegative integrable weight function w on the unit circle T , we provide an expression for p = 2, in terms of the series coefficients of the outer function of w, for the weighted Lp distance inff T |1 − f |pwdμ, where μ is the normalized Lebesgue measure and f ranges over trigonometric polynomials with frequencies in [{. . . ,−3,−2,−1}\{−n}]∪{m}, m ≥ 0, n ≥ 2. The problem is open for p = 2.

Prediction of Satranidazole Solubility in Water-Polyethylene Glycol 400 Mixtures Using Extended Hildebrand Solubility Approach
The Extended Hildebrand Solubility Parameter Approach (EHSA) is used to estimate the solubility of satranidazole in binary solvent systems. The solubility of satranidazole in various water-PEG 400 mixtures was analyzed in terms of solute-solvent interactions using a modified version of Hildebrand-Scatchard treatment for regular solutions. The solubility equation employs term interaction ...
