The inflected possessive form of the type of Russian ixnij, its rise and variation across the East Slavic dialects and languages are analyzed. Whereas this form has been long fluctuated on the verge of Standard Russian and nevertheless has not been accepted as normative, it has been successfully adopted into Standard Ukrainian (superseding the older jix form) and widely used in Belarusian, although reluctantly accepted in grammars and dictionaries.
As a first step in developing better molecular scale understanding of the effects of organic additives on the adsorption and mobility of radionuclides in cement under conditions of geological nuclear waste repositories, two complementary approaches, wet chemistry experiments and molecular dynamics (MD) computer simulations, were applied to study the sorption behaviour of two simple model systems: gluconate and uranyl on calcium silicate hydrate phases (C-S-H) - the principal mineral component of hardened cement paste (HCP). Experimental data on sorption and desorption kinetics and isotherms of adsorption for gluconate/C-S-H and U(VI)/C-S-H binary systems were collected and quantitatively analysed for C-S-H samples synthesised with various Ca/Si ratios (0.83, 1.0, 1.4) corresponding to various stages of HCP aging and degradation. Gluconate labelled with 14C isotope was used in order to improve the sensitivity of analytical detection technique (LSC) at particularly low concentrations (10(-8) -10(-5) Â mol/L). There is a noticeable effect of Ca/Si ratio on the gluconate sorption on C-S-H, with stronger sorption at higher Ca/Si ratios. Sorption of organic anions on C-S-H is mediated by the presence of Ca(2+) at the interface and strongly depends on the surface charge and Ca(2+) concentration. In parallel, classical MD simulations of the same model systems were performed in order to identify specific surface sorption sites most actively involved in the sorption of gluconate and uranyl on C-S-H and to clarify molecular mechanisms of adsorption.
The structure of Russians' life course has never been studied in depth; the only exception is demographic studies regarding marital status and age at childbirth. Principles that define life trajectories should also be examined. The “adult” concept is one of a number of important concepts in the general structure of life planning. This article presents an agenda for future research based on several case studies obtained during a longitudinal study of educational and occupational trajectories. Studying the transition into adulthood is an important resource for understanding the modern times. However, another option is also possible. This concept of transition into adulthood can also be considered as a phenomenon of contemporary culture. The research perspective of cultural sociology, whose methodology is described as structural hermeneutics, can serve these purposes. Structural hermeneutics refers to an analysis of the structure of senses both intersubjective and collectively shared. It is important to analyze how the adult concept is used with regard to the structure of the life course in materials from Russian studies, with account for the ambivalence of this concept and research conducted in other countries.
В статье рассмотрены основные ключевые факторы, влияющие на стоимость и инженерную сложность дата центров, определяющие базовые правила формирования и оценки стоимости создания и последующей эксплуатации. Понятие энергоэффективность, каково влияние энергоэффективности дата-центра на его первичную стоимость, стоимость эксплуатации, и как следствие: Совокупная стоимость владения.
The world economy relies on access to industrial metals, oil and gas for maintaining its critical industrial infrastructure. Although demand is likely to remain high, the most accessible deposits have been depleted. Future capacity growth will be facilitated through further technological developments. Russia as a leading producer is paying great attention to strengthening its competitive edge in global markets. This paper reports on a large-scale technology foresight study of the Russian extractive sector (including oil and gas), which combined expert-based foresight activities with statistical analyses and text-mining techniques based on artificial intelligence and machine learning technologies. The presented methodology helped to link the technologies to dominant discussions (e.g. climate change vs rural development) and to flag key trends. Furthermore, quantitative estimates can be identified quickly. The study’s methodology should function as an example for similar studies to support policy planning and investment decisions based on text-mining techniques.
