Elaborating principles of idiom-formation in the avant-garde literary discourse: a case study of Russian Cubo-Futurism

The paper sets out to explore the avant-garde literary discourse from the point of view of its idiomatic constituent. In particular, it studies avant-garde manifestoes written by the representatives of Cubo- Futurism, in which radical aesthetic renewal and the need for the reformation in the sphere of literature are proclaimed. As very expressive and complex rhetorical performances, manifestoes contain various kinds of idiomatic phrases that can be considered both vivid representations of a particular (avant-garde) approach to the language and prescriptions for certain ways of the language use. Special attention is paid to the elaboration of the methodology aimed to identify avant-garde idioms proper in the avant-garde literary discourse. The results obtained show that the manifestoes under consideration are, in essence, the first “trials” in the field of (poetic) language reformation and language experimentation and the sources of the idiomatics (idioms / idiomatic expressions) that can be termed “experimental”

Energy efficiency of external walls of buildings with aggressive production environments

Much attention is paid now to the energy efficiency of external enclosing structures. The study of this issue is especially important for external walls, operating in an aggressive environment. The author proposed the light polymer-silicate shungizit concrete (LPSC) for exterior walls of buildings with acidic, wet-gas environments. Shungizite as a lightweight aggregate was chosen because of its high acid resistance. The experience of using shungizit concrete on cement binder for structures of residential, public and industrial buildings was olso taken into account. Previously, the author conducted studies on the physic-mechanical properties of LPSC with a density of 1000 -1200 kg/m3. Studies have shown that this material can be applied to the exterior walls of buildings with acidic, wet-gas environments. This article presents the results of studies on the energy efficiency of walls made of LPSC

Postsynaptic Mechanisms Are Essential for Forskolin-Induced Potentiation of Synaptic Transmission

It has been demonstrated that stimulation of protein kinase A (PKA) results in enhanced synaptic transmission in the hippocampus and other brain areas. To investigate mechanisms of the PKA-mediated potentiation of synaptic transmission, we used rat hippocampal embryonic cultures. In low-density cultures, paired recordings under the perforated patch demonstrated that 15-min forskolin treatment produced long-lasting potentiation of evoked excitatory postsynaptic currents (eEPSCs) mediated by the cAMP/PKA pathway. eEPSC amplitudes increased to 240 ± 10% of baseline after 15 min of forskolin treatment (early). After forskolin washout, eEPSCs declined to a potentiated level. Potentiation was sustained for ≥85 min after forskolin washout and, 60 min after forskolin washout, constituted 152 ± 7% of baseline (late potentiation). Disruption of presynaptic processes with the whole cell configuration and internal solution containing PKA inhibitor peptide did not affect forskolin-induced potentiation. Disruption of postsynaptic processes, in contrast, impaired early potentiation and abolished late potentiation. Study of mEPSCs confirmed the contribution of postsynaptic mechanisms. Forskolin-induced enhancement of mEPSC frequency observed under the perforated patch was attenuated by the whole cell configuration. Forskolin also induced an increase of mEPSC amplitudes in the perforated patch, but not in the whole cell, experiments. Potentiation of eEPSCs was not activity dependent, persisting in the absence of stimulation. NMDA receptor blockade did not abolish forskolin-induced potentiation. In summary, we demonstrate that forskolin-induced potentiation of eEPSCs was mediated by postsynaptic mechanisms, presumably by upregulation of AMPA receptors by phosphorylation

The study of spectral and luminescent properties of humic acids and their impact on the photodegradation process of 2,6-bis(hydroxymethyl)-4-methylphenol

UV photolysis (KrCl excilamp, λ rad ~ 222 nm) of aqueous humic acids (HAs) samples was carried out without and in the presence of 2,6-bis(hydroxymethyl)-4-methylphenol. The samples of HAs fractions were obtained from Aldrich Chemical Co and prepared from peat of Arkhangelsk region. The presence of Aldrich humic acid in the solution has a essential effect on the processes of phenolic compound photochemical degradation under the action of light from the excilam

Economic tools for realization of methane production project on Kuzbass coal deposits

Environmental issues and, above all, issues related to the release of greenhouse gases into the atmosphere, such as coal bed methane, actualize the challenge of searching a variety of options for its disposal. The difference in the macroeconomic, industrial, geological and infrastructural features determine the need to choose the most cost-effective option for using of methane emitted from the coal deposits. Various economic ways to improve the profitability of production are viewed on the basis of the analysis of methane production project from Kuzbass coal deposits, Kemerovo region, Russia
