ON ZYGMUND–TYPE INEQUALITIES CONCERNING POLAR DERIVATIVE OF POLYNOMIALS

open access: yesUral Mathematical Journal, 2021
Let \(P(z)\) be a polynomial of degree \(n\), then concerning the estimate for maximum of \(|P'(z)|\) on the unit circle, it was proved by S. Bernstein that \(\| P'\|_{\infty}\leq n\| P\|_{\infty}\).

Search for Non-Protein Protease Inhibitors Constituted with an Indole and Acetylene Core

open access: yesMolecules, 2021
A possible inhibitor of proteases, which contains an indole core and an aromatic polar acetylene, was designed and synthesized. This indole derivative has a molecular architecture kindred to biologically relevant species and was obtained through five ...

Ordered smectic phase formed by novel binary liquid crystalline systems consisting of low-molecular-weight polar compounds and an amorphous side-chain polymer

open access: yesStudies in Science and Technology, 2023
Novel binary liquid crystalline systems were obtained by mixing amorphous side-chain polymethacrylate (SCP) and polar compounds. Their thermal and orientational properties were examined by DSC measurement, polarizing microscopy and temperature-variable X-

The polar sciences journal: the past and future of a crucial research instrument

open access: yes, 2022
Journals dedicated to the polar sciences have been outliers. Within both the history of science and the history of media, they stand out in several ways, including their comparatively late establishment of peer-review. It was not until the second half of

Gas-liquid chromatographic analyses of 1,2-ethanediol monoethers and monoesters

open access: yesJournal of Lipid Research, 1968
Synthetic mixtures of saturated and unsaturated monoethers and monoesters of 1,2-ethanediol, ranging in chain length from 12 to 20, were analyzed as acetates, trifluoroacetates (TFA), and trimethylsilyl (TMS) ethers by gas chromatography on polar and ...
