Problems of research of speech activities of bilingual students in the context of contemporary linguistic situation

Situation of bilinguism is discussed on the basis of people speaking both Armenian (native for the person or his/her ancestors) and Russian. One of the languages is, as a rule, dominating in the mind of the bilingual person, it “forces out” the second, though the ideal situation may occur when both languages are equal, their usage is accompanied by meta-language reflection on both of them, their differences and similarities.Рассматривается ситуация билингвизма на примере людей, владеющих как армянским (родным для себя или предков), так и русским языками. Демонстрируется, что, как правило, один из языков в сознании билингва является доминирующим, «вытесняет» другой, хотя наблюдается и ситуация, признаваемая идеальной, – равное владение обоими языками, сопровождающееся метаязыковой рефлексией по поводу каждого из них, их сходства и различия

Surface-dependent differences in the adsorption of pancreatic and microbial ribonucleases visualized by atomic force microscopy

A comparative study of the physical adsorption of RNAse A and RNAse Bacillus pumilis onto a negatively charged surface of mica, a hydrophobic surface of pyrolytic graphite and a surface of lipid layers of dipalmitoylphosphatidylcholine (DPPC) was performed by atomic force microscopy. It was found that microbial RNAse, unlike RNAse A, 1) is adsorbed onto the negatively charged surface of mica in the form of monomers and dimers; 2) exhibits enhanced tropism to the hydrophobic surface of pyrolytic graphite; 3) modifies morphotopography and thickness of the lipid bilayer of DPPC. The detected surface-dependent differences in adsorption of RNAses are consistent with the features of their structure and cytotoxic properties

Genetic control of scald resistance in barley landraces

Scald (Rhynchosporium secalis (Oudem.) J.J. Davis pathogenic agent) is one of the most harmful barley diseases. A high variability of this fungi explains the occurrence of new aggressive pathotypes and, accordingly, loss of cultivar resistance. It was found that many recently selected varieties of barley and previously identified sources of resistance to R. secalis are now susceptible to the pathogen. There is only one gene, Rrs9, that maintains efficiency against pathogen populations in Russia. The aim of this study is to find donors of genes for effective resistance to scald with the ability to easily transfer this trait for hybridization. The inheritance of scald resistance in 33 barley landraces was studied. Analysis of the interaction between the pathogen test clones and the host plant revealed a difference between the alleles determining fungal resistance in 32 barley forms, the previously effective genes Rrs4, rrs6, rrs7, and currently effective Rrs9. It was found that 30 accessions are protected by new unidentified genes for scald resistance. Accessions k-18398 and k-16231 from China are likely to possess allelic genes for scald resistance, while the gene (or genes) of accession k-31075 from Nepal is allelic to the Rrs9 gene. It was demonstrated by hybridological analysis that accessions k-3307, k-15868, k-18989 and k-3481 are protected by effective genes for scald resistance, which differ from each other and which are not allelic to the Rrs4, rrs6, rrs7 or Rrs9 genes. Accessions k-15868 and k-3481 possess two complementary recessive genes for scald resistance, k-18989 has two recessive genes, and k-3307 carries one recessive gene for pathogen resistance. The resistance genes of these forms are manifested during all the stages of plant ontogenesis

Postural regulation of teenagers performing pop dance, according to stabilometry data

Knowledge of postural regulation in different sports is useful for sports selection and for improvement of postural stereotypes.Objective: to reveal postural regulation features of teenagers involved in pop dance.Materials and methods: 15 pop dancers involved in dance more than 10 years performed Romberg and optokinetic tests on computer stabilograph “Trust-M Stabilo”.Results: the area and length of the dancers’ statokinesiogram were less than in general sample, statokinesiogram’s pressure center had been dextrally dislocated. Visual disturbances as well as vision deprivation led to statistically significant increase in speed of center of pressure movement along reference plane and in the ratio of statokinesiogram’s length to its area. All these changes were less pronounced than in the general sample.Conclusions: postural regulation of dancers proved to be better than that of healthy people who were not involved in sports

Simultaneous electrical conductivity and DTA measurements in the study of the phosphonate-phosphate rearrangement and accompanying processes

The application of DTA with the simultaneous recording of electrical conductivity variation in the study of the thermal behaviour of α-oxyalkylphosphonates and their analogues is considered. The investigation of electrical conductivity variation during a reaction helps clarify certain problems of the phosphonate-phosphate rearrangement and the decomposition of α-oxyalkylphosphonates to their components. © 1974 Wiley Heyden Ltd., Chichester and Akadémiai Kiadó, Budapest

Adaptive potential of spring durum wheat (<i>Triticum durum</i> Desf.) under the conditions of Primorsky Territory

Background. The research goal was to study spring durum wheat cultivars from different regions of Russia to select those that were most adapted to the conditions of Primorsky Territory and had high yield and grain quality.Materials and methods. The adaptive potential of 16 genotypes was determined through multi-environment trials at the Federal Scientific Center of Agricultural Biotechnology of the Far East named after A.K. Chaika in 2017–2021.Results. Considerable potential for high productivity was revealed in the cultivars: ‘Solnechnaya 573’ (3.9 t/ha), ‘Donskaya elegiya’ (3.8 t/ha), ‘Lyudmila’ (3.8 t/ha), ‘Omskii izumrud’ (3.8 t/ha), and ‘Voronezhskaya 7’ (3.8 t/ha). Cvs. ‘Pamyati Yanchenko’ (–2.1), ‘Zhemchuzhina Sibiri’ (–2.4), and ‘Voronezhskaya 7’ (–2.4) displayed significant stress resistance. ‘Lyudmila’ (4.2) and ‘Donskaya elegiya’ (4.0) had high genetic plasticity and produced high yields in the years with favorable conditions. The adaptability coefficient of cvs. ‘Solnechnaya 573’ (112.5%) and ‘Voronezhskaya 7’ (111.0%) exceeded 100%. ‘Donskaya elegiya’, ‘Lyudmila’, ‘Aleiskaya’, and ‘Voronezhskaya 9’ demonstrated the highest plasticity (bi &gt; 1). The most stable cultivars were ‘Omskii tsirkon’ (S2di – 0.00), ‘Pamyati Yanchenko’ (S2di – 0.02), ‘Voronezhskaya 7’ (S2di – 0.04), ‘Aleiskaya’ (S2di – 0.05), ‘Nikolasha’ (S2di – 0.06), and ‘Omskaya biryuza’ (S2di – 0.08). ‘Voronezhskaya 7’ and ‘Pamyati Yanchenko’ were able to produce an increased yield and had the minimum yield loss under unfavorable conditions (the indicator of the yield stability of the cultivars was 134.9 and 144.8, respectively). ‘Pamyati Yanchenko’ (4.8 and 1.9, respectively) and ‘Voronezhskaya 7’ (3.5 and 2.0, respectively) showed high homeostatic capacity and breeding value.Conclusions. ‘Voronezhskaya 7’ and ‘Solnechnaya 573’ were selected on the basis of complex evaluation for yield and adaptability under the local conditions. They can be recommended for further breeding and production

The energy gap of intermediate-valent SmB6 studied by point-contact spectroscopy

We have investigated the intermediate valence narrow-gap semiconductor SmB6 at low temperatures using both conventional spear-anvil type point contacts as well as mechanically controllable break junctions. The zero-bias conductance varied between less than 0.01 mikrosiemens and up to 1 mS. The position of the spectral anomalies, which are related to the different activation energies and band gaps of SmB6, did not depend on the the contact size. Two different regimes of charge transport could be distinguished: Contacts with large zero - bias conductance are in the diffusive Maxwell regime. They had spectra with only small non-linearities. Contacts with small zero - bias conductance are in the tunnelling regime. They had larger anomalies, but still indicating a finite 45 % residual quasiparticle density of states at the Fermi level at low temperatures of T = 0.1 K. The density of states derived from the tunelling spectra can be decomposed into two energy-dependent parts with Eg = 21 meV and Ed = 4.5 meV wide gaps, respectively.Comment: 9 pages incl. 13 figure
