The impact of nanoporous carbon material (PCM) morphology on its electrochemical behavior in aqueous electrolyte has been studied. The optimum concentration of aqueous lithium sulfate which provides the maximum specific energy characteristics of capacitor-type systems C/Li2SO4/C is determined. Capacitive parameters of electrochemical capacitors (EC) in aqueous so­lutions of lithium, sodium and potassium sulfate which have different molar ratio have been stu­died by comparative analysis. Cyclic voltammograms at different scan rates show that the PCM ca­pacitive behavior in three electrolytes increases in the following order Li2SO4<Na2SO4<K2SO4. This imp­rovement could be a result of increasing the movement speed of hydrated ions in the volume of electrolyte and in the internal pores of PCM in the order Li+<Na+<K+. The obtained results give valuable information for the study of new hybrid supercapacitors.

The current paper presents a comprehensive literature review of research into the phenomenon of Russian national identity and emphasizes the crucial role of discourse metaphor in narratives of national culture and identity. The latter, as a complex mental construct, encompasses common or similar beliefs or opinions internalized in the course of socialization as well as emotional attitudes, behavioural and linguistic dispositions. The paper claims that Russian patriotism-based national identity construction is directly related to the historical background, current political ideology, as well as objectives and tasks the state sets. Patriotic sentiments in Russia tend to boost due to some life-changing dramatic events or challenges the country has to face; this gives rise to employing a multitude of discursive practices, which rely heavily on discourse metaphors. The relevant point the paper proposes lies in the fact that discourse metaphors, being conceptually grounded, serve as a pervasive cognitive mechanism applied to explain a complex abstract concept of national identity. However, its meaning is still being shaped in relation to a particular period of time and the context where a debate is unfolding. Unlike conceptual metaphors that are considered to be universal, independent of time, discourse metaphors change or evolve within the ongoing discourse and are intended for specific purposes. The current paper seeks to demonstrate how particular metaphors can serve as discursive mechanisms of constructing the national identity to achieve both culturally and historically specific strategic purposes. The authors claim that a combination of co-occurring metaphors in the public discourse forms a holistic extended metaphorical narrative promoting a particular view of Russianness and focus on some of them.

The magic word of the last years is internationalization. Researchers more and more focus on export market information and the relationship between this information and export performance. Just a few studies take into account the impact of firm characteristics on these topics. This study shows that country-of-origin, sector and size class (both individually and simultaneously) influence both the number of information sources consulted, and the type of information provider consulted. Besides, the relationship between the amount of export market information and export sales is not straightforward, but needs to be corrected for these three firm characteristics. These conclusions have implications for governmental export promotion campaigns, for the information behaviour of SME-managers, and for the strategies of information providers.

This article examines the fine art of the Soviet national republics and its discourse in the Soviet Union, which were considerably shaped under the influence of socialist realism and Soviet nationality policy. While examining the central categories of Soviet artistic discourse such as the "national form," "national distinctness," and "tradition," as well as cultural and scientific institutions responsible for the image of art of non-Russian nationalities, the author reveals the existence of a number of colonial features and discursive and institutional practices that foster a cultural divide between Russian and non-Russian culture and contribute to the marginalization of art. Special attention is paid to the implications of this discursive shaping for the local artistic scene in Buryatia.
