    Based on the established essential characteristics and the structure of professional training of students, taking into account the results of the observational experiment, the levels of future preschools’ teachers search and research skills formation of preschool institutions were determined. The methods of scientific research were the analysis of scientific and methodological literature, educational documentation on pedagogical practice, questionnaires of future educators, as well as observation of research activities of students of higher education institutions. Analysis of psychological and pedagogical research, conducting a statement experiment made it possible to establish the features of the structural elements of research activities. The research experiment made it possible to check the level of formation of research skills in students – future educators of preschool education, as well as how they master the motivational-value, content-procedural, research components of professional training, acquire knowledge and research skills. The results of the inspection were carried out in accordance with the developed criteria, indicators and levels of research skills of future educators of preschool educational institutions

    Measurement of the temperature dependence of pulse lengths in an n-type germanium detector

    Full text link
    The temperature dependence of the pulse length was measured for an 18-fold segmented n-type germanium detector in the temperature range of 77-120 K. The interactions of 122 keV photons originating from a Europium-152 source were selected and pulses as observed on the core and segment electrodes were studied. In both cases, the temperature dependence can be well described by a Boltzmann-like ansatz.Comment: 17 pages, 2 tables, 13 figures, published in EPJ A

    Signal recognition efficiencies of artificial neural-network pulse-shape discrimination in HPGe 0Ξ½Ξ²Ξ²0\nu\beta\beta-decay searches

    Get PDF
    A pulse-shape discrimination method based on artificial neural networks was applied to pulses simulated for different background, signal and signal-like interactions inside a germanium detector. The simulated pulses were used to investigate variations of efficiencies as a function of used training set. It is verified that neural networks are well-suited to identify background pulses in true-coaxial high-purity germanium detectors. The systematic uncertainty on the signal recognition efficiency derived using signal-like evaluation samples from calibration measurements is estimated to be 5\%. This uncertainty is due to differences between signal and calibration samples

    Examining c-di-GMP and possible quorum sensing regulation in Pseudomonas fluorescens SBW25:links between intra and inter-cellular regulation benefits community cooperative activities such as biofilm formation

    Get PDF
    Bacterial success in colonizing complex environments requires individual response to micro-scale conditions as well as community-level cooperation to produce large-scale structures such as biofilms. Connecting individual and community responses could be achieved by linking the intracellular sensory and regulatory systems mediated by bis-(3β€²-5β€²)-cyclic dimeric guanosine monophosphate (c-di-GMP) and other compounds of individuals with intercellular quorum sensing (QS) regulation controlling populations. There is growing evidence to suggest that biofilm formation by many pseudomonads is regulated by both intra and intercellular systems, though in the case of the model Pseudomonas fluorescens SBW25 Wrinkly Spreader in which mutations increasing c-di-GMP levels result in the production of a robust cellulose-based air-liquid interface biofilm, no evidence for the involvement of QS regulation has been reported. However, our recent review of the P. fluorescens SBW25 genome has identified a potential QS regulatory pathway and other QS–associated genes linked to c-di-GMP homeostasis, and QS signal molecules have also been identified in culture supernatants. These findings suggest a possible link between c-di-GMP and QS regulation in P. fluorescens SBW25 which might allow a more sophisticated and responsive control of cellulose production and biofilm formation when colonising the soil and plant-associated environments P. fluorescens SBW25 normally inhabits.Анализ Ρ†-Π΄ΠΈ-Π“ΠœΠ€ ΠΈ Π²ΠΎΠ·ΠΌΠΎΠΆΠ½ΠΎΠ³ΠΎ чувства ΠΊΠ²ΠΎΡ€ΡƒΠΌΠ° Ρƒ Pseudomonas fluorescens SBW 25: связь ΠΌΠ΅ΠΆΠ΄Ρƒ Π²Π½ΡƒΡ‚Ρ€ΠΈ ΠΈ ΠΌΠ΅ΠΆΠΊΠ»Π΅Ρ‚ΠΎΡ‡Π½ΠΎΠΉ рСгуляциСй способствуСт ΠΊΠΎΠΎΠΏΠ΅Ρ€Π°Ρ‚ΠΈΠ²Π½ΠΎΠΌΡƒ повСдСнию Π² сообщСствС ΠΈ Ρ„ΠΎΡ€ΠΌΠΈΡ€ΠΎΠ²Π°Π½ΠΈΡŽ Π±ΠΈΠΎΠΏΠ»Ρ‘Π½ΠΊΠΈΠ£ΡΠΏΠ΅ΡˆΠ½ΠΎΡΡ‚ΡŒ Π±Π°ΠΊΡ‚Π΅Ρ€ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ ΠΊΠΎΠ»ΠΎΠ½ΠΈΠ·Π°Ρ†ΠΈΠΈ слоТных экониш Ρ‚Ρ€Π΅Π±ΡƒΠ΅Ρ‚ ΠΈΠ½Π΄ΠΈΠ²ΠΈΠ΄ΡƒΠ°Π»ΡŒΠ½ΠΎΠ³ΠΎ ΠΎΡ‚Π²Π΅Ρ‚Π° Π½Π° измСнСния условий Π½Π° ΠΌΠΈΠΊΡ€ΠΎΡƒΡ€ΠΎΠ²Π½Π΅ Ρ€Π°Π²Π½ΠΎ ΠΊΠ°ΠΊ ΠΈ ΠΊΠΎΠΎΠΏΠ΅Ρ€Π°Ρ†ΠΈΠΈ Π½Π° ΡƒΡ€ΠΎΠ²Π½Π΅ сообщСства для ΠΏΡ€ΠΎΠ΄ΡƒΠΊΡ†ΠΈΠΈ Ρ‚Π°ΠΊΠΈΡ… ΠΊΡ€ΡƒΠΏΠ½ΠΎ ΠΌΠ°ΡΡˆΡ‚Π°Π±Π½Ρ‹Ρ… структур ΠΊΠ°ΠΊ Π±ΠΈΠΎΠΏΠ»Ρ‘Π½ΠΊΠΈ.

    Derivatives have become common instruments for a wide range of users, including financial institutions, companies that manage assets, corporations, hedge funds. These instruments allow for speculative, arbitrage and hedging operations, which defines them as useful instruments to stimulate the growth of the efficiency of financial markets and the real economy. In this article based on 21 macroeconomic and financial indexes of the USA by test of Granger’s relation of cause and effect have been investigated influences of the exchange market of derivatives on indicators of economic growth of the USA. In this article is used a large amount of statistical data of time series and variables of macroeconomic and financial indices. The results of a research have confirmed positive correlation and causality of indicators of economic growth from use of exchange derivatives in real economy. It is received for the studied period of 2000-2015 proofs that the exchange market of derivatives of the USA positively influences the economic. The results obtained during the study can be used to substantiate the necessary measures aimed on the development of the derivatives market in Ukraine

    The MGDO software library for data analysis in Ge neutrinoless double-beta decay experiments

    Full text link
    The GERDA and Majorana experiments will search for neutrinoless double-beta decay of germanium-76 using isotopically enriched high-purity germanium detectors. Although the experiments differ in conceptual design, they share many aspects in common, and in particular will employ similar data analysis techniques. The collaborations are jointly developing a C++ software library, MGDO, which contains a set of data objects and interfaces to encapsulate, store and manage physical quantities of interest, such as waveforms and high-purity germanium detector geometries. These data objects define a common format for persistent data, whether it is generated by Monte Carlo simulations or an experimental apparatus, to reduce code duplication and to ease the exchange of information between detector systems. MGDO also includes general-purpose analysis tools that can be used for the processing of measured or simulated digital signals. The MGDO design is based on the Object-Oriented programming paradigm and is very flexible, allowing for easy extension and customization of the components. The tools provided by the MGDO libraries are used by both GERDA and Majorana.Comment: 4 pages, 1 figure, proceedings for TAUP201
