Reaction of aromatic aldehydes with aniline and tropylium tetrafluoroborate yielded N-arylmethylene-4-(7-cyclohepta-1,3,5-trienyl)anilines, while reaction of aromatic aldehydes with aniline, tropylium tetrafluoroborate, and sodium tetrahydroborate afforded N-arylmethyl-4-(7-cyclohepta-1,3,5-trienyl)anilines. Two most promising compounds, N-2-hydroxyphenylmethylene-4′-(7-cyclohepta-1,3,5-trienyl)aniline and N-2-hydroxyphenylmethyl-4′-(7-cyclohepta-1,3,5-trienyl)aniline, were tested for acute toxicity (LD50) and their low toxicity was revealed. © 2017, Pleiades Publishing, Ltd.

Reactions of 4- and 4′-substituted chalcones with naphthalen-2-amine afforded isomeric benzo[g]- and benzo[f]quinoline derivatives. Depending on the substituent in the initial chalcone, the cyclization follows two pathways through different intermediates. The product structure was confirmed by IR, 1H and 13C NMR, and mass spectra and X-ray analysis. © 2017, Pleiades Publishing, Ltd.

Generalization of experimental results and mathematical models of the effect of ultra-high-frequency (UHF) electromagnetic radiation on details fabricated from energetic polymer materials are presented. Different types of phenomena in irradiated details are dependent on the size of the detail, free path radiation length in the material, absorbed energy, and rate of input of the radiant energy to the material. © 2016, Pleiades Publishing, Ltd.

The content of heavy metals in the soils of the Middle CisUrals (the town of Chusovoi and its vicinities) is controlled by both natural and technogenic factors. The enrichment of the parent rocks in Cr, Pb, Zn, and Cu, which influences the chemical composition of the soils, is the most important among the natural factors. Among the other natural factors, the gleying and washing of the alluvial soils with flood water are significant. The technogenic contamination of the urban soils reaches its maximum in the technozems, where the content of Cu, Zn, Pb, and Cr exceeds their clarkes by 4-8 times. The index of technogeneity (the share of technogenic metals referring to their total content) is high for the bulk of metals in technozems, in particular, ranging within 36-97%. The technogeneity sequence is the following for the urban soils: Cr > Zn = Mn > Pb > Cu > Fe. The soil contamination with metals is confined to the depression where the metallurgical plant is operating, and it significantly falls already at a distance of 2-3 km in the settlements located at higher topographic positions. © 2010 Pleiades Publishing, Ltd.

The contents of heavy alkaline-earth (Sr and Ba) and rare-earth (Y, La, and Ce) metals have been studied in two technogeochemical anomalies and in the soils of Perm and Chusovoi. The soils are contaminated with barium, lanthanum, and cerium in the territory of the Cherepovets technogeochemical anomaly formed due to the atmospheric emissions from the Severstal metallurgical works. Strontium, barium, and yttrium are accumulated in the soils of the Revda technogeochemical anomaly formed by aerial emissions from the Mid-Urals copper smelter. The portion of technogenic strontium reaches 43-84% near the metallurgical works, while that of barium and yttrium, 47-63 and 28-32%, respectively. In Perm, the urban soils are polluted with technogenic alkaline-earth metals, i. e., strontium and barium, with their content reaching 31-48%. In Chusovoi, the calcareous horizons of the soddy soils are enriched in strontium and depleted in barium. The eluvial-illuvial distribution of the rare-earth metals is registered in the soddy-podzolic soil. The soils of the terrace are contaminated with barium. The technozem is contaminated with all the metals (barium and yttrium, in particular). © 2010 Pleiades Publishing, Ltd.

Higher values of the energies of the highest occupied molecular orbitals for N-benzyl-4-[9-(thio)-xanthenyl]aniline, N-benzyl-4-(5-dibenzosuberenyl) aniline molecules and their zwitterions and the electron density increase on the reaction center (carbon atom in the CH2-group) for the latter were obtained in the quantum-chemical calculations by RHF/6-31G(d) method. This explains the possibility and the ease of dehydrogenation of N-benzyl-4-[9-(thio) xanthenyl]aniline with imines in trifluoroacetic acid due to effect of the substituents. The calculated data suggest the same possibility for N-benzyl-4-(5-dibenzosuberenyl)aniline: it is dehydrogenated already in the synthesis from N-benzylaniline and dibenzosuberenol in acetic acid. © 2013 Pleiades Publishing, Ltd.

The article discusses the aspects of establishment of food sovereignty from the regional point of view. Herewith, it is mentioned that the established food sovereignty of a state should be based on food sovereignty of regions as separate administrative and territorial units. The most prioritized field of development of agro-industrial complex is rational distribution and efficient specialization of agricultural and processing utilities. In this regard the article proposes a procedure to zone territories on the basis of specialization level of agriculture, which makes it possible to reveal the most competitive branches. Optimal territorial specialization would play one of the major roles with regard to food sovereignty of regions and recovery of fully functional interregional links at the Russian food markets. Comprehensive analysis has been performed for the regions of Volga Federal District of Russian Federation. Based on ranking of the obtained results the most competitive regions of the considered Federal District have been revealed in terms of number of agricultural branches. The performed study into agro-industrial complex of the regions has facilitated establishment of long-term measures aimed at increase in efficiency of branches of agro-industrial complex. © IDOSI Publications, 2013.
