Modular technology of corporate formation of blue-collar workers’ professional competency

Topicality of the problem under investigation is conditioned by implementation of competency oriented federal state educational standards and professional standards into the practice of blue-collar workers training, the mentioned standards being intended to disclose the host of functions of various blue-collar occupations and WorldSkills standards reflecting modern world trends in the field of formation and development of blue-collar workers’ professional competences. In the meaningful aspect, today’s standards identifying requirements to blue-collar workers training will define principles of selection and formation of competency oriented subject matter of training; however, the choice of training technologies quite often remains beyond the training standards. At the same time, the competency oriented training of blue-collar workers shall envisage application of the activity approach to organization and realization of the training and, consequently, of technologies of training based on the activity approach. The modular technology of training based on points of European concept of “Modular employable skills” can be one of such technologies. The purpose of the article is description of the authors’ modular technology of forming of workers’ professional competency under conditions of corporate training. The modular technology is described herein as exemplified by formation of professional competency of workers of the machine-building industry in field of lathe part machining. The article also includes results of an experimental approbation of a developed modular technology in conditions of plants’ training centers. The investigation’s leading method shall be a pedagogical educational experiment in process whereof the modular technology of forming of workers’ professional competency which has been developed by the authors shall be approbated, the mentioned workers belonging to the machine-building industry in field of lathe part machining, whereas a worker’s professional competency is regarded as an integrated aggregate of core competencies and occupational personal properties which lie in the base of the selection and structuring of the subject matter of training. Materials and methods: the pedagogical educational experiment allows exposing the efficiency of complex formation of the professional competency in trainees by means of applying of the modular technique of training and methodological support, that is, educational elements developed in line with requirements of Modular employable skills concept and supplemented with a set of production tasks performed directly on the job under the tutor’s guidance. The following methods were used in process of the research: theoretical (analysis, synthesis, deduction and induction); diagnostic (methods of analysis and systemizing of scientific pedagogical literature; generalization and classification); empirical (modelling). The key results described in the article: the professional competency model of the machine-building industry workers; the modular technology of forming of professional competency of the machine-building industry workers; the methodological support elaborated in line with requirements of Modular employable skills concept, plus results of the experimental approbation of the developed modular technology. The modular approach, possessing systemic properties, allows integrating the substantive basis of training formed in the competency-based format, processes of selection and structuring of the content of blue-collar workers’ training reflected in the program documentation fixed forms, educational-methodological documentation represented by training elements, organization- methodological aspects of training, organization and realization of training which are also recorded in documentary form in line with requirements of Modular employable skills concept. © 2018 by the authors

Label-free electrochemical monitoring of DNA ligase activity

This study presents a simple, label-free electrochemical technique for the monitoring of DNA ligase activity. DNA ligases are enzymes that catalyze joining of breaks in the backbone of DNA and are of significant scientific interest due to their essential nature in DNA metabolism and their importance to a range of molecular biological methodologies. The electrochemical behavior of DNA at mercury and some amalgam electrodes is strongly influenced by its backbone structure, allowing a perfect discrimination between DNA molecules containing or lacking free ends. This variation in electrochemical behavior has been utilized previously for a sensitive detection of DNA damage involving the sugar-phosphate backbone breakage. Here we show that the same principle can be utilized for monitoring of a reverse process, i.e., the repair of strand breaks by action of the DNA ligases. We demonstrate applications of the electrochemical technique for a distinction between ligatable and unligatable breaks in plasmid DNA using T4 DNA ligase, as well as for studies of the DNA backbone-joining activity in recombinant fragments of E. coli DNA ligase

INHERITANCE OF TEXTURE AT α→γ→α–TRANSFORMATION IN LOW-CARBON LOW–ALLOY STEEL

Методом ориентационной микроскопии исследованы текстуры образцов малоуглеродистой низколегированной стали после контролируемой термомеханической обработки (TMCP) и последующих термических обработок, включающих двойную фазовую перекристаллизацию. После термических обработок в полученных структурах (бейнит, мартенсит, феррит) наблюдались текстуры, ориентировки которых были связаны с основными ориентировками аустенита при его горячей деформации в процессе TMCP ориентационными соотношениями (ОС), промежуточными между ОС Курдюмова – Закса и Нишиямы – Вассермана. Во всех случаях факт ориентационной связи компонент текстур объяснен началом реализации фазовых превращений на специальных границах.The textures of low-carbon low-alloy steel samples obtained by controlled thermomechanical processing (TMCP) and subsequent heat treatments including a double phase recrystallization was studied by EBSD. Texture was observed after the heat treatments in the resulting structures (bainite, martensite, ferrite). In the resulting textures, the orientations were associated with of the main orientations of the austenite at its hot deformation during TMCP by orientation ratios (OR) intermediate between OR Kurdyumov – Sachs and Nishiyama – Wasserman. In all cases, the fact of the orientation due textures components explained the beginning of the implementation of phase transformations on CSL boundaries.Работа выполнена в рамках проектной темы Минобрнауки РФ (задание № 11.1465.2014/K).

The development and characteristics of a hand-held high power diode laser-based industrial tile grout removal and single-stage sealing system

As the field of laser materials processing becomes ever more diverse, the high power diode laser (HPDL) is now being regarded by many as the most applicable tool. The commercialisation of an industrial epoxy grout removal and single-stage ceramic tile grout sealing process is examined through the development of a hand-held HPDL device in this work. Further, an appraisal of the potential hazards associated with the use of the HPDL in an industrial environment and the solutions implemented to ensure that the system complies with the relevant safety standards are given. The paper describes the characteristics and feasibility of the industrial epoxy grout removal process. A minimum power density of approximately 3 kW/cm2 was found to exist, whilst the minimum interaction time, below which there was no removal of epoxy tile grout, was found to be approximately 0.5 s. The maximum theoretical removal rate that may be achievable was calculated as being 65.98 mm2/s for a circular 2 mm diameter beam with a power density of 3 kW/cm2 and a traverse speed of 42 mm/s. In addition, the characteristics of the single-stage ceramic tile grout sealing are outlined. The single-stage ceramic tile grout sealing process yielded crack and porosity free seals which were produced in normal atmospheric conditions. Tiles were successfully sealed with power densities as low as 550 W/cm2 and at rates of up to 420 mm/min. In terms of mechanical, physical and chemical characteristics, the single-stage ceramic tile grout was found to be far superior to the conventional epoxy tile grout and, in many instances, matched and occasionally surpassed that of the ceramic tiles themselves

High precision measurement of the associated strangeness production in proton proton interactions

A new high precision measurement of the reaction pp -> pK+Lambda at a beam momentum of 2.95 GeV/c with more than 200,000 analyzed events allows a detailed analysis of differential observables and their inter-dependencies. Correlations of the angular distributions with momenta are examined. The invariant mass distributions are compared for different regions in the Dalitz plots. The cusp structure at the N Sigma threshold is described with the Flatt\'e formalism and its variation in the Dalitz plot is analyzed.Comment: accepted for publication in Eur. Phys. J.

First Model-Independent Measurement of the Spin Triplet pΛp\Lambda Scattering Length from Final State Interaction in the p⃗p→pK+Λ\vec{p}p \rightarrow pK^{+}\Lambda Reaction

The $\vec{p}p \rightarrow pK^{+}\Lambda$ reaction has been measured with the COSY-TOF detector at a beam momentum of $2.7\,\mathrm{GeV}/c$. The polarized proton beam enables the measurement of the beam analyzing power by the asymmetry of the produced kaon ($A_N^{K}$). This observable allows the $p\Lambda$ spin triplet scattering length to be extracted for the first time model independently from the final-state interaction in the reaction. The obtained value is $a_{t} = (-2.55 ^{+0.72}_{-1.39} {}_{\textrm{stat.}} \pm 0.6_{\textrm{syst.}} \pm 0.3_{\textrm{theo.}})\mathrm{fm}$. This value is compatible with theoretical predictions and results from model-dependent analyses.Comment: Revised version as accepted for publication in PR

Dynamic Merge of the Global and Local Models for Sustainable Land Use Planning with Regard for Global Projections from GLOBIOM and Local Technical–Economic Feasibility and Resource Constraints

In order to conduct research at required spatial resolution, we propose a model fusion involving interlinked calculations of regional projections by the global dynamic model GLOBIOM (Global Biosphere Management Model) and robust dynamic downscaling model, based on cross-entropy principle, for deriving spatially resolved projections. The proposed procedure allows incorporating data from satellite images, statistics, expert opinions, as well as data from global land use models. In numerous case studies in China and Ukraine, the approach allowed to estimate local land use and land use change projections corresponding to real trends and expectations. The disaggregated data and projections were used in national models for planning sustainable land use and agricultural development

The HypHI project: Hypernuclear spectroscopy with stable heavy ion beams and rare isotope beams at GSI and FAIR

The HypHI collaboration aims to perform a precise hypernuclear spectroscopy with stable heavy ion beams and rare isotope beams at GSI and fAIR in order to study hypernuclei at extreme isospin, especially neutron rich hypernuclei to look insight hyperon-nucleon interactions in the neutron rich medium, and hypernuclear magnetic moments to investigate baryon properties in the nuclei. We are currently preparing for the first experiment with $^6$Li and $^{12}$C beams at 2 AGeV to demonstrate the feasibility of a precise hypernuclear spectroscopy by identifying $^{3}_{\Lambda}$H, $^{4}_{\Lambda}$H and $^{5}_{\Lambda}$He. The first physics experiment on these hypernuclei is planned for 2009. In the present document, an overview of the HypHI project and the details of this first experiment will be discussed.Comment: 5 pages, 2 figures, French-Japanese symposium 2008, Paris (France
