The technology of developing the Electronic Scientific Agricultural Library the E-library structure are discussed. The E-library comprises two databases: the Knowledge E-library and the Document Collections E-library (ELC) being developed in accordance with the general concept of the industryβs E-library. The ELC is an element of the Centralized Electronic Library System and is integrated into the minor cloud library and information system (MOBIS). MOBIS provides services for the participating librariesβ designing their own digital catalogs and electronic libraries. The document type composition, search options and several services are described. Inclusion of fulltext databases increases significantly its volume as well as the quality of user information services.The authors conclude that the Electronic Scientific Agricultural Library should supplement the library collection of printed materials and valuable documents, to widen access to the Libraryβs collections, to increase the user number and to deliver documents to any place. The Electronic Scientific Agricultural Library has been being developing and appended with new documents from its own collection and external sources.Π Π°ΡΡΠΌΠΎΡΡΠ΅Π½Ρ ΡΠ΅Ρ

Synthesis and Application of Arylaminophosphazene as a Flame Retardant and Catalyst for the Polymerization of Benzoxazines
A novel type of phosphazene containing an additive that acts both as a catalyst and as a flame retardant for benzoxazine binders is presented in this study. The synthesis of a derivative of hexachlorocyclotriphosphazene (HCP) and meta-toluidine was carried out in the medium of the latter, which made it possible to achieve the complete substitution of chlorine atoms in the initial HCP. Thermal and flammability characteristics of modified compositions were investigated. The modifier catalyzes the process of curing and shifts the beginning of reaction from 222.0 Β°C for pure benzoxazine to 205.9 Β°C for composition with 10 phr of modifier. The additive decreases the glass transition temperature of compositions. Achievement of the highest category of flame resistance (V-0 in accordance with UL-94) is ensured both by increasing the content of phenyl residues in the composition and by the synergistic effect of phosphorus and nitrogen. A brief study of the curing kinetics disclosed the complex nature of the reaction. An accurate two-step model is obtained using the extended ProutβTompkins equation for both steps
