SPECIAL ASPECTS OF THE SECOND FOREIGN LANGUAGE TEACHING AT THE BASIC COURSE

The aim of this work is to define special aspects of the second foreign language (SFL) grammar teaching at the basic course, because at Ukrainian universities the number of course hours for studying of the SFL is less than for the first one. This leads to more superficial learning of grammar material. In addition, it was believed that the grammar of the SFL can be taught in the context of the general course. The integration of vocabulary and grammar teaching hampered the thorough understanding of grammatical constructions by the students, as the study of the SFL came against the background of the first foreign language enhanced studying. For the scientific analysis of this issue, the methods of causality analysis and generalization were applied, which helped identify the priority of the communicative approach in the SFL grammar teaching, as this approach develops the oral and written skills of students. Nevertheless, there are some factors that impede the fluency of grammar material at the basic course of education. The article reveals problems and ways to solve them during the training. The authors consider that the communicative approach in the SFL grammar teaching will help master the language more quickly and efficiently, which meets the needs of modern society

COMPETENCE AS A CONCEPT IN PROFESSIONAL TRAINING OF FUTURE SPECIALISTS

The article considers the content of the concept of “professional competenc” of a specialist through the competence that forms the basis for the development of standards for higher education and emphasizes the crucial importance of professional skills of future specialists. In the article, the authors follow the approach outlined in the Memorandum letter of the Ministry of Education and Science of Ukraine regarding the development of components of the system of higher education. Competence is considered as an integrated characteristic of personality traits, the result of the preparation of a graduate of the university for the performance of activities in certain professional and socio-personal subject areas (competencies), which is determined by the required volume and level of knowledge and experience in a particular type of activity

Hexokinase inhibits flux of fluorescently labeled ATP through mitochondrial outer membrane porin

AbstractMitochondrial function requires maintaining metabolite fluxes across the mitochondrial outer membrane, which is mediated primarily by the voltage dependent anion channel (VDAC). We applied fluorescence correlation spectroscopy (FCS) to study regulation of the VDAC functional state by monitoring distribution of fluorescently labeled ATP (BODIPY-FL-ATP) in isolated intact rat liver and heart mitochondria. Addition of mitochondria to BODIPY-FL-ATP solution resulted in accumulation of the fluorescent probe in these organelles. The addition of hexokinase II (HKII) isolated from rat heart led to a decrease in the BODIPY-FL-ATP accumulation, while a 15-residue peptide corresponding to the N-terminal domain of hexokinase did not produce this effect. Therefore, the hexokinase-induced inhibition of the ATP flow mediated by VDAC was revealed in isolated mitochondria

Determinants of serum concentrations of perfluoroalkyl acids (PFAAs) in school children and the contribution of low-level PFAA-contaminated drinking water

Little is known about the demographic/life-style/physiological determinants explaining the variation of serum perfluoroalkyl acid (PFAA) concentrations in children. We identified significant determinants in children and investigated the influence of low-level PFAA-contaminated drinking water (DW) (<10 ng L−1 of single PFAAs) on serum concentrations. Four perfluorosulfonic acids (PFSAs) and 11 perfluorocarboxylic acids (PFCAs) were analyzed in serum from 5th grade children from 11 Swedish schools (N = 200; average age: 12 years) using liquid chromatography-tandem-mass-spectrometry. Data on demography and life-style/physiological factors were obtained by questionnaires. PFAA concentrations in raw and drinking water (DW) were obtained from the water works supplying DW to the schools. In multiple regression analyses school was the determinant contributing most to the variation in PFAA concentrations, with the lowest contribution for PFHpA (10%) and the highest for PFHxS (81%). Girls had lower adjusted mean concentrations of PFHxS, PFOS, PFNA and PFDA than boys, but a higher concentration of PFHxA. Girls reporting onset of menstruation had lower PFHxS and PFOA concentrations than other girls, suggesting menstrual bleeding elimination. Children born by mothers from less industrialized countries had lower mean concentrations of both PFSAs and PFCAs than children with mothers from highly industrialized countries, suggesting differences in early-life exposure. Life-style factors associated with paternal education levels appeared to influence PFAA concentrations differently than maternal education level. Already at an average DW PFHxS concentration of 2 ng L−1, children had a significantly higher adjusted mean serum PFHxS concentration than at an average DW concentration of <1.6 ng PFHxS L−1. Similar results were observed for PFOS and PFOA. The DW variable explained 16% (PFOA) to 78% (PFHxS) of the variation in serum PFAA concentrations, suggesting that low-level-contaminated DW is a significant source of exposure for children in Sweden. Although some of the associations, especially those with menstruation and maternal birth country, should be interpreted with extra caution due to the small size of the study, the results contribute to future work on identifying populations of children at risk of elevated PFAA exposures

Synthesis, crystal structure and electrophysical properties of triple molybdates containing silver, gallium and divalent metals

A possibility of the triple molybdates formation with both NASICON-like and NaMg3In(MoO4)5 structures in the Ag2MoO4–AMoO4–Ga2(MoO4)3 (A = Mn, Co, Zn, Ni) systems was studied by powder X-ray diffraction analysis. It was established that NASICON-like phases Ag1−xA1−xGa1+x(MoO4)3 are not formed. The triple molybdates AgA3Ga(MoO4)5 (A = Mn, Co, Zn) isostructural to triclinic NaMg3In(MoO4)5 (sp. gr. P`1, Z = 2) were synthesized and characterized. The structure of the obtained compounds was refined for AgZn3Ga(MoO4)5  according to the powder data by the Rietveld method. The structure consists of MoO4 tetrahedra, couples of edge-shared M(1)O6 octahedra, and trimers of edge-shared M(2)O6-, M(3)O6- and M(4)O6 octahedra, which are linked by the common vertices to form a 3D framework. High-temperature conductivity measurements revealed that the conductivity of AgMn3Ga(MoO4)5 at 500 °С reaches 10-2 S/cm, which is close to one of the known NASICON-type ionic conductors
