Implementation Features and Development Prospects in Distance Learning of Russian as a Foreign Language (RFL) at Pre-University Faculty
The aim of this article is to describe the experience of e-learning of Russian as a Foreign Language (RFL) at the Pre-University Faculties based on the examples of three Russian educational organizations of higher education. The authors summarized the practical experience of Pre-University Faculties shift to e-learning in the period of the COVID-19 spread; the article also makes analysis of specific features characterizing this shift, describes the specifics of shifting the lessons into a digital mode and also examines the prospects of development of digital environment for the RFL Pre-University Faculty students. On the basis of the analysis, the authors describe the most common difficulties which faced both students and teachers. The results of this research show that distant learning became the only available instrument of the educational process functioning in the period of self-isolation when it was impossible to conduct face-to-face lessons. During the pandemic, the organization of the educational process, including studying at the Pre-University Faculty, became the new starting point for the development, promotion and prospects of e-learning technologies in the field of education
Conformational analysis of 1,3,2-dioxaphospholane and pyrocatehine phosphite with Oc(O)Cf 3 exocyclic substituents
Conformational analysis of 1,3,2-dioxaphospholane-2-yl-2,2,2- trifluoroacetate and 4,5-benzo-1,3,2-dioxaphosphole-2-yl-2,2,2-trifluoroacetate was carried out by dipole moment method and quantum chemical calculations (DFT B3LYP/6-31G). Β© 2013 Copyright Taylor and Francis Group, LLC

Conformational analysis of 1,3,2-dioxaphospholan-2-yl 2,2,2- trifluoroacetate and 4,5-benzo-1,3,2-dioxaphosphol-2-yl 2,2,2-trifluoroacetate was carried out using the method of dipole moments and quantumchemical calculations (DFT B3LYP/6-31G*). Both compounds are found to exist as an axial conformer with preferably syn arrangement of the carbonyl group and the lone electron pair. Β© 2012 Pleiades Publishing, Ltd
Mechanism of the hydrolysis reactions of 1-hydroxysilatrane and 1-hydroxygermatrane, 2,2-dihydroxysilocane and 2,2-dihydroxygermocane
Β© 2016 Taylor & Francis Group, LLC.The mechanism of the hydrolysis reactions of 2,2-dihydroxysilocane, 2,2-dihydroxygermocane, 1-hydroxysilatrane, and 1-hydroxygermatrane was studied by the density functional theory method. According to the quantum chemical calculations, the reactions of hydrolysis for 2,2-dihydroxysilocane and 2,2-dihydroxygermocane are characterized by the lower values of activation energy than for 1-hydroxysilatrane and 1-hydroxygermatrane. The ring configurations of the hydrolysis products are stable due to the presence of transannular interaction NβX (X = Si, Ge) and intramolecular hydrogen bond in their molecules
Mechanism of the Reactions of (2,2-Dimethyl-1-((Trimethylsilyl)Oxy)Propylidene)-(Trimethylsilyl)Phosphine with Nucleophilic and Electrophilic Reagents
Copyright Β© 2015 Taylor & Francis Group, LLC. The mechanism of the reaction of 3,3-dimethyl-2-trimethylsiloxy-1-trimethylsilyl-1-phosphabut-1-ene with bis(phenylendioxy)chlorophosphorane was studied by the density functional theory method. According to the quantum chemical calculations this interaction occurs in parallel on two reaction centers: PII atom (electrophilic substitution) and O atom (nucleophilic substitution)
THE STUDY OF HUMORAL FACTORS OF ADAPTIVE IMMUNITY IN PATIENTS WITH NON-HODGKINβS LYMPHOMAS
It is known that humoral factors of immunity play an important function of mediators in the cascade development of the immune response and can determine the effectiveness of the final, effector reactions of cellular immunity in the inactivation and elimination of antigens. Serum concentrations of major immunoglobulins IgG, IgA, IgM in NHL were analyzed. The highest serum content of IgG and IgA was revealed in the groups of patients with virus carrier. It has been established that one of the most important humoral markers of immunity is the circulating immune complexes (CIC). It has been established that one of the most important biological functions of immunoglobulins is antigen binding and the formation of CIC. A high level of CIC in NHL may be due not only to the activation of the immune response, but also to the suppression of the mechanisms of their elimination. Therefore, based on the results obtained, with NHL there is a pronounced imbalance of humoral immunity. CIC of large and small sizes are also increased, however, the highest increase in CIC was observed in groups of patients before chemotherapy with virus-bearing. An increase in the main immunoglobulins indicates the presence of humoral imbalance, and an increase in the CIC indicates the presence of intoxication of the body either due to the decay of the tumor cells themselves and infected cells, which almost always indicates the progression of the pathological process.It is known that humoral factors of immunity play an important function of mediators in the cascade development of the immune response and can determine the effectiveness of the final, effector reactions of cellular immunity in the inactivation and elimination of antigens.

Conformational analysis of secondary arylalkylphosphine selenides
Conformational analysis of bis(2-phenylalkyl)phosphine selenides was performed by the dipole moment method and quantum-chemical calculations. Bis(2-phenylpropyl)phosphine selenide was found to exist as a mixture of several conformers, the most energetically favorable of which being characterized by gauche (non-eclipsed) orientation of the P=Se and Csp3-C sp3 bonds.

Conformational analysis of 1-sila-4-phospha-2,5-cyclohexadienes
Conformational analysis of 1-sila-4-phospha-2,5-cyclohexadienes was performed using the methods of dipole moments and quantum-chemicall calculations (DFT B3LYP/6-31G*). Irrespective of the degree of coordination of the phosphorus atom (3 or 4) the unsaturated six-membered heterocycles adopt the conformation of a flattened boat with the exocyclic phenyl group oriented perpendicular to the double bonds of the heterocycle. This conformation rules out the possibility of intramolecular transannular interaction between the phosphorus and silicon atoms. Β© Pleiades Publishing, Ltd., 2011
