The 4-arylaminocoumarin derivatives log P values calculated according to Rekker's method

open access: yesBiomolecules & Biomedicine, 2003
In the QSAR (quantitative structure-activity relationship) and QSPR (quantitative structure-property-activity relationship) study physico-chemical property, lipophilicity is used, to predict bioactivity of the newly synthesized coumarin compounds ...

Log-Minkowski inequalities for the Lp $L_{p}$-mixed quermassintegrals

open access: yesJournal of Inequalities and Applications, 2019
Böröczky et al. proposed the log-Minkowski problem and established the plane log-Minkowski inequality for origin-symmetric convex bodies. Recently, Stancu proved the log-Minkowski inequality for mixed volumes; Wang, Xu, and Zhou gave the Lp $L_{p ...

Correlation between retention constants obtained in reversed-phase liquid chromatography and partition coefficients of some benzimidazole derivatives [PDF]

open access: yesActa Periodica Technologica, 2004
Several calculation procedures for log P values based on the fragmental and atomic contributions are compared with experimental reversed-phase liquid chromatography (RPLC) retention constants of benzimidazole derivatives.

Examination of lipophilicity and toxicity of azo dyes derivatives

open access: yesZaštita Materijala, 2017
Azo dyes, in addition to showing a wide range of applications in various industries, after releasing into aquatic ecosystems can act as pollutants. The first step in the prediction of possible toxic effects of compounds in the environment includes the ...

On p-adic vanishing cycles of log smooth families [PDF]

open access: yesTunisian Journal of Mathematics, 2020
In this paper, we will show that the sheaf of p-adic vanishing cycles of a log smooth family over a DVR of mixed characteristic is generated by Milnor symboles. A key ingredient is a computation (due to K. Kato) on the graded quotients of a multi-indexed filtration on the sheaf concerned, which has been used in several papers of the first author.

Gravity tectonics controls on reservoir-scale sandbodies: Insights from 3D seismic geomorphology of the canyons buried in the upper slope of the Eastern Niger delta basin

open access: yesEnergy Geoscience
High-resolution 3D seismic data analysis was integrated with a calibrated well and biostratigraphy data to present the first overview of a buried Pleistocene canyon system on the upper slope of the eastern Niger Delta, the Galabor Canyon.

The Log-effect for p-evolution type models

open access: yesJournal of the Mathematical Society of Japan, 2008
The authors consider the Cauchy problem for the one evolution operators, that is, \[ D^2_t- \sum^{2p}_{|\alpha|=0} a_\alpha(t) D^\alpha_x u- \sum^{p-1}_{|\alpha|= 0} b_\alpha(t) D^\alpha_x D_t u= 0,\quad t> 0,\;x\in\mathbb{R}^n, \] \[ u(0, x)= u_0(x),\qquad u_t(0, x)= u_1(x).

Asymptotic r-log-convexity and P-recursive sequences [PDF]

open access: yesJournal of Symbolic Computation, 2019
A sequence $\{ a_n \}_{n \ge 0}$ is said to be asymptotically $r$-log-convex if it is $r$-log-convex for $n$ sufficiently large. We present a criterion on the asymptotical $r$-log-convexity based on the asymptotic behavior of $a_n a_{n+2}/a_{n+1}^2$.
