Formation of the Yukaghir National School

The problems of preserving the language and culture of small ethnic groups are relevant in world society. The Yukaghirs are one of the disappearing ethnic groups due to their small number and long-term adaptation in a multi-ethnic environment that does not contribute to the development and preservation of linguistic and cultural traditions. The lack of a language environment, scientifically grounded educational programs and teaching materials, violation of psychological foundations that contribute to the preservation of an ethnic group are the main bases of the relevance of the study. The article presents the results of a long-term educational experiment on the preservation of the Yukaghir language and culture in the Nelemnoye secondary school of the Verkhnekolymsky district of the Republic of Sakha (Yakutia), the successful management of the educational process in the new conditions, its progressive expansion, development, and creation of a socio-educational space to preserve the native language and culture in the Yukaghir village. The practical results of the experiment can be used to solve similar problems in the world's educational society

Photodegradation of methylene green in the presence of polypropylene microfiber material

Degradation of toxicants in photocatalytic reactor is studied. To an array of data on the photochemical properties of Methylene Green (MG) when exposed to UV radiation in photoreactors was obtained. Based on the analysis of the results obtained, conclusions can be drawn about the relationship between the structure of pollutants, their initial concentration, oxidizer concentration, etc., with the efficiency of utilization, and schemes for photochemical processes was constructed. The role of polypropylene microfiber materials (PMM) in the degradation of MG under UV irradiation was studied

Los yukaghires son uno de los grupos étnicos en desaparición debido a su pequeño número y adaptación a largo plazo en un entorno multiétnico que no contribuye al desarrollo y preservación de las tradiciones lingüísticas y culturales. La falta de un entorno lingüístico, programas educativos y materiales didácticos fundamentados científicamente, la violación de los fundamentos psicológicos que contribuyen a la preservación de un grupo étnico son las principales bases de la relevancia del estudio. El artículo presenta los resultados de un experimento educativo a largo plazo sobre la preservación de la lengua y la cultura Yukaghir en la escuela secundaria Nelemnoye del distrito Verkhnekolymsky de la República de Sakha (Yakutia), la gestión exitosa del proceso educativo en las nuevas condiciones, su progresiva expansión, desarrollo y creación de un espacio socioeducativo para preservar la lengua y cultura nativas en la aldea Yukaghir. Los resultados prácticos del experimento se pueden utilizar para resolver problemas similares en la sociedad educativa mundial

Direct formylation of 2-pyridone core of 3-<i>N</i>-methylcytisine via Duff reaction; synthesis of 9-enyl, 9-ynyl and 9-imino derivatives

<p>The first direct synthesis of 3-<i>N</i>-methyl-9-formylcytisine via electrophylic formylation is described. It is established, that Vilsmeier-Haack and Gatterman variants of this reaction are unsuccessful in the case with 3-substituted (-)-cytisine derivatives, but Duff procedure (with hexamethylenetetramine in trifluoroacetic acid) gives a possibility to obtain the target pseudo aromatic aldehyde with the 69% yield. Convenient precursors for [4 + 2]- or [3 + 2]-cycloaddition reactions are obtained by means of condensation of synthesized 3-<i>N</i>-methyl-9-formylcytisine with acetone, nitromethane and phosphorous ylides with yields from 70 to 87%. Alternative aprroach to alkenyl products and to 9-alkynyl-3-methylcytisine is realized using the Heck and Sonogashira cross-coupling reactions of methyl vinyl ketone, cyclohexenone or trimethylsilylacetylene with 9-bromo-3-methylcytisine (55, 70 and 60% accordingly). It is shown, that interaction of 3-<i>N</i>-methyl-9-formylcytisine with hydroxylamines leads to corresponding nitrone (93%) and oxime (70%). All individual compounds are isolated by column chromatography and completely characterized on the basis of NMR spectroscopy data.</p

Mitigating of Thin-Film Composite PTMSP Membrane Aging by Introduction of Porous Rigid and Soft Branched Polymeric Additives

This work was focused on the mitigation of physical aging in thin-film composite (TFC) membranes (selective layer ~1 μm) based on polymer intrinsic microporosity (PTMSP) by the introduction of both soft, branched polyethyleneimine (PEI), and rigid, porous aromatic framework PAF-11, polymer additives. Self-standing mixed-matrix membranes of thicknesses in the range of 20–30 μm were also prepared with the same polymer and fillers. Based on 450 days of monitoring, it was observed that the neat PTMSP composite membrane underwent a severe decline of its gas transport properties, and the resultant CO2 permeance was 14% (5.2 m3 (STP)/(m2·h·bar)) from the initial value measured for the freshly cast sample (75 m3 (STP)/(m2·h·bar)). The introduction of branched polyethyleneimine followed by its cross-linking allowed to us to improve the TFC performance maintaining CO2 permeance at the level of 30% comparing with day zero. However, the best results were achieved by the combination of porous, rigid and soft, branched polymeric additives that enabled us to preserve the transport characteristics of TFC membrane as 43% (47 m3 (STP)/(m2·h·bar) after 450 days) from its initial values (110 m3 (STP)/(m2·h·bar)). Experimental data were fitted using the Kohlrausch–Williams–Watts function, and the limiting (equilibrium) values of the CO2 and N2 permeances of the TFC membranes were estimated. The limit value of CO2 permeance for neat PTMSP TFC membrane was found to be 5.2 m3 (STP)/(m2·h·bar), while the value of 34 m3(STP)/(m2·h·bar) or 12,600 GPU was achieved for TFC membrane containing 4 wt% cross-linked PEI, and 30 wt% PAF-11. Based on the N2 adsorption isotherms data, it was calculated that the reduction of the free volume was 1.5–3 times higher in neat PTMSP compared to the modified one. Bearing in mind the pronounced mitigation of physical aging by the introduction of both types of fillers, the developed high-performance membranes have great potential as support for the coating of an ultrathin, selective layer for gas separation
