FACILITATION OF CHORUS ROLE IN A. N. ARBUZOV’S PARABLE “THE HAPPY DAYS OF AN UNHAPPY MAN” [PDF]

Philology. Theory & Practice, 2018
The article is devoted to the analysis of the facilitated image of the chorus and its functions in the parable “The Happy Days of an Unhappy Man”, which was written by the Soviet playwright A. N. Arbuzov in 1967. It is proved that in the play the playwright simplifies the role of the chorus, facilitates its presence on the stage.

‘Enthusiasts’ and ‘Fanatics’: The Decembrists as a Case Study in French Influence on Russian Culture, Emotions and Thought

History, EarlyView.
Abstract Participants in Russia's 1825 Decembrist uprising against the Tsarist regime were, quite literally, a case study in French cultural influence upon Russia. This is particularly true as it relates to Russia's emotional cultures. Although this has not, traditionally, been the primary focus of historical analysis of this event (in Soviet or ...

Practical and Efficient Synthesis of (E)-α,β-Unsaturated Amides Incorporating α-Aminophosphonates via the Horner–Wadsworth–Emmons Reaction

Molecules
An efficient and practical procedure for the synthesis of (E)-α,β-unsaturated amides incorporating α-aminophosphonates, derived from readily accessible phosphonoacetamides, via the Horner–Wadsworth–Emmons (HWE) reaction was developed.

Lanthionine Ketenamine Derivative Enhances Early Functional Recovery Following Skeletal Muscle Ischemia‐Reperfusion Injury Through Modulation of Autophagy and Oxidative Stress

Journal of Orthopaedic Research, Volume 44, Issue 9, September 2026.
ABSTRACT Ischemia‐reperfusion injury (IRI) induces skeletal muscle damage through oxidative stress, impaired autophagy, and satellite cell (SC) dysfunction, ultimately compromising regenerative capacity and functional recovery. We investigated whether the naturally occurring autophagy‐stimulating compound 2‐n‐hexyl lanthionine ketenamine phosphonate (2‐

Chlorine‐Free Synthesis of P‐Esters: Microwave‐Assisted Direct Esterification of Phosphinic, Phosphonic, as Well as Phosphoric Acid Derivatives

Chemistry–Methods, Volume 6, Issue 7, July 2026.
The esterification of phosphinic, phosphonic, and phosphoric acids is not possible due the high enthalpy of activation. However, the barrier may be overcome under MW irradiation to give phosphinates, phosphonates, and alkoxyphosphoric acids, respectively. In the latter cases, the remaining P(O)OH group was esterified by alkylation.

Enthusiasms of Scale model boat clubs of Cornwall

, 2022
Many seaside towns in Cornwall possess a human-made, Victorian era, boating lake. These watery, placid, civic structures tend to occur in towns where part of their peripheral boundary is defined by a much larger, uncontained and wild ocean. Boating lakes

Chemical Syntheses of 3′ and 5′ Phosphorylated Oligonucleotides: An Overview

European Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.
This review provides an overview of the various chemical methods employed in the synthesis of oligonucleotides bearing a phosphate group at their 3′ or 5′ end. Notably, it presents modified phosphoramidites and supports developed for this purpose. Oligonucleotides (ON) with a phosphate monoester group at their 3′ or 5′ end have applications in many ...
