The social responsibility of dual education in an unstable environment

BACKGROUND AND OBJECTIVES: In a context of instability caused by various crises, including military crises, the higher education system is at great risk. Practice-oriented (dual) education is one of the most effective ways to address this problem. The innovation of this study is that for the first time a theoretical and practical model for involving all stakeholders in this process has been created and tested. The aim of the article is to substantiate a socially responsible dual education system in an unstable environment.METHODS: In terms of objective, this is an applied and quantitative study. The study population is estimated at 13 universities, 10 companies, 50 students between November 2021 and November 2022. The sample size is estimated using the Cochrane formula. A standard 5-point Likert scale questionnaire was used to collect data, where groups of questions corresponded to 4 hypotheses. All data were investigated by factor and cluster analysis using STATISTICA software (version 10.0).FINDINGS: All four hypotheses were confirmed. Before the war, the first and second hypotheses were prioritized. According to them, the process approach of social responsibility of dual education allows designing and launching a system of social responsibility of dual education and creating a talent pool at the employing enterprise. After the outbreak of hostilities, the priorities changed. The third and fourth hypotheses allow, through the organization of supportive (enabling) processes, to ensure the effective functioning of the system. As a result, the majority of stakeholders (31%) consider it necessary to modernize the mentoring system and provide graduates with relevant professional skills, while methodological and career guidance came in second and third (16% and 13% respectively).CONCLUSION: Using the theoretical and practical model of formation and implementation of dual education in the unstable conditions of Ukraine will help to solve the problems of the country out of crisis, post-war recovery of higher education system, to bring the requirements of production with the possibilities of training specialists in universities and can be applied in other countries in a similar situation

SND@LHC: The Scattering and Neutrino Detector at the LHC

SND@LHC is a compact and stand-alone experiment designed to perform measurements with neutrinos produced at the LHC in the pseudo-rapidity region of ${7.2 < \eta < 8.4}$. The experiment is located 480 m downstream of the ATLAS interaction point, in the TI18 tunnel. The detector is composed of a hybrid system based on an 830 kg target made of tungsten plates, interleaved with emulsion and electronic trackers, also acting as an electromagnetic calorimeter, and followed by a hadronic calorimeter and a muon identification system. The detector is able to distinguish interactions of all three neutrino flavours, which allows probing the physics of heavy flavour production at the LHC in the very forward region. This region is of particular interest for future circular colliders and for very high energy astrophysical neutrino experiments. The detector is also able to search for the scattering of Feebly Interacting Particles. In its first phase, the detector will operate throughout LHC Run 3 and collect a total of 250 $\text{fb}^{-1}$

Measurement of jet suppression in central Pb-Pb collisions at root s(NN)=2.76 TeV

The transverse momentum(p(T)) spectrum and nuclear modification factor (R-AA) of reconstructed jets in 0-10% and 10-30% central Pb-Pb collisions at root s(NN) = 2.76 TeV were measured. Jets were reconstructed using the anti-k(T) jet algorithm with a resolution parameter of R = 0.2 from charged and neutral particles, utilizing the ALICE tracking detectors and Electromagnetic Calorimeter (EMCal). The jet p(T) spectra are reported in the pseudorapidity interval of \eta(jet)\ 5 GeV/c to suppress jets constructed from the combinatorial background in Pb-Pb collisions. The leading charged particle requirement applied to jet spectra both in pp and Pb-Pb collisions had a negligible effect on the R-AA. The nuclear modification factor R-AA was found to be 0.28 +/- 0.04 in 0-10% and 0.35 +/- 0.04 in 10-30% collisions, independent of p(T), jet within the uncertainties of the measurement. The observed suppression is in fair agreement with expectations from two model calculations with different approaches to jet quenching. (C) 2015 CERN for the benefit of the ALICE Collaboration.

Elliptic flow of identified hadrons in Pb-Pb collisions at 1asNN = 2.76 TeV

The elliptic flow coefficient (v2) of identified particles in Pb-Pb collisions at 1asNN = 2.76 TeV was measured with the ALICE detector at the Large Hadron Collider (LHC). The results were obtained with the Scalar Product method, a two-particle corre- lation technique, using a pseudo-rapidity gap of | 06\u3b7| > 0.9 between the identified hadron under study and the reference particles. The v2 is reported for \u3c0\ub1, K\ub1, K0S, p+p, \u3c6, \u39b+\u39b, \u39e 12+\u39e+ and \u3a9 12+\u3a9+ in several collision centralities. In the low transverse momentum (pT) region, pT 3 GeV/c

COMPOSITION OF BIOLOGICALLY ACTIVE SUBSTANCES AND ANTIRADICAL ACTIVITY OF EXTRACTS FROM FIVE SPECIES OF PLANTS OF THE ASPARAGACEAE FAMILY

Many members of the Asparagaceae family are used in traditional medicine in different countries and characterized by a high content of biologically active metabolites. In this work, the qualitative composition and quantitative content of the components of methanol extracts from leaves and underground organs of Sansevieria cylindrica Bojer ex Hook, Sansevieria trifasciata Prain, Polianthes tuberosa L., leaves of Yucca filamentosa L. and Furcraea gigantea var. watsoniana (Hort. Sander) Drumm. were determined. Extraction of plant leaves and underground organs using 80% methanol resulted in 5.2-16.7% and 16-25.1% of the total extractive substances consequently. The presence of steroidal saponins in the extracts was shown by thin layer chromatography. Spirostanol saponins were predominate in the extracts from leaves of Y. filamentosa, F. gigantea and underground organs of S. cylindrica, S. trifasciata, P. tuberosa, furastanol saponins - in the extracts from leaves of S. cylindrica and S. trifasciata. The content of terpenoid and phenolic compounds in the extracts established using spectrophotometry significantly differs depending on the plant species and their anatomical part. All the extracts tested exhibited inhibition of the 2,2-diphenyl-1-picrylhydrazyl free radical in dose-dependent manner. The highest antiradical activity demonstrated the extract from the leaves of Y. filamentosa (IC50 = 25.95 μg/ml) containing the largest amount of phenolic compounds, including flavonoids - 51.3 and 15.5% of the total extractive substances

Hydrothermal Activation of Porous Nitrogen Doped Carbon Materials for Electrochemical Capacitors and Sodium Ion Batteries

Highly porous nitrogen doped carbon nanomaterials have distinct advantages in energy storage and conversion technologies. In the present work, hydrothermal treatments in water or ammonia solution were used for modification of mesoporous nitrogen doped graphitic carbon, synthesized by deposition of acetonitrile vapors on the pyrolysis products of calcium tartrate. Morphology, composition, and textural characteristics of the original and activated materials were studied by transmission electron microscopy, X ray photoelectron spectroscopy, near edge X ray absorption fine structure spectroscopy, infrared spectroscopy, and nitrogen gas adsorption method. Both treatments resulted in a slight increase in specific surface area and volume of micropores and small mesopores due to the etching of carbon surface. Compared to the solely aqueous medium, activation with ammonia led to stronger destruction of the graphitic shells, the formation of larger micropores 1.4 nm vs. 0.6 nm , a higher concentration of carbonyl groups, and the addition of nitrogen containing groups. The tests of nitrogen doped carbon materials as electrodes in 1M H2SO4 electrolyte and sodium ion batteries showed improvement of electrochemical performance after hydrothermal treatments especially when ammonia was used. The activation method developed in this work is hopeful to open up a new route of designing porous nitrogen doped carbon materials for electrochemical application
