The Intercorp Parallel Corpus with a Uniform Annotation for All Languages
Authors: Rosen Alexandr 
Published: December 2023

Abstract
Recently, the language-specific morphosyntactic annotation of InterCorp, a large multilingual parallel corpus, has been replaced by the language-uniform morphosyntactic and syntactic annotation following the guidelines of the Universal Dependencies project. Because the corpus is used predominantly by human users via a token-based concordancer, the CONLL-U format produced by the UDP ipe parser has been extended by attributes such as lemma of the token’s syntactic head or morphosyntactic categories of the content verb’s auxiliary. We conclude that despite some theoretical and practical issues, the new annotation is a promising solution to the issue of mutually incompatible tagsets within a single corpus.
Syllabic Consonants in Historical Czech and How to Identify Them
Authors: Ziková Markéta , Březina Martin , Čech Radek , Kosek Pavel 
Published: December 2023

Abstract
The paper provides fine-grained evidence concerning the development of syllabic consonants /r l/ in Czech, that is only sketched in the existing literature. The evidence is based on an automatic parser that identifies potential syllable-projecting segments according to sonority. The parser was applied to six verse texts from the 14th–16th centuries, which show a strong tendency towards octosyllabicity. The data provided by the parser newly reveal that the shift from non-syllabic to syllabic /r l/ is position-dependent: word-medial non-syllabic strings C(r/l)C change more rapidly than non-syllabic word-final ones C(r/l)#. This finding is in line with a cross-linguistic observation that non-syllabic C(r/l)C are marked, hence they are regularly syllabified prior to less marked C(r/l)#.

Published: December 2023

Abstract
This article aims to examine the potential relationship between Brent crude oil futures prices and the index of the European renewable energy companies. After the overview of the European legislation and the most recent literature review on the topic, the article deploys a method of the Vector Autoregressive Model (VAR). The analysis includes weekly data over eight years (2015-2022). Our results indicate a positive correlation between Brent crude oil futures prices and the value of the European Renewable Energy Total Return (ERIX) index. The estimated bivariate VAR model indicates a statistically significant relationship, meaning that past values of the ERIX Index may be used to predict future Brent crude oil prices in the long run. Considering the most recent systemic disturbance in the world’s commodity market, future research should consider longer time series and possible relationships of other macroeconomic factors.

Introduction. A differential diagnostic search is a crucial method for making a final clinical diagnosis. Lack of clinical thinking leads to tactical errors, both in making a diagnosis and in choosing a therapy algorithm. The problem of iatrogeneses especially often arises at the initial stages of patient management.Case descriptions. The paper demonstrates the difficulties of verifying the diagnosis of patients with dermatological pathology on the example of clinical cases. The stages of differential diagnostic search are covered in detail. Practicing physicians stress the importance of timely correct diagnosis and, consequently, the choice of therapy. The study involved a detailed analysis of clinical cases and mistakes causing a delay in diagnosis and wrong choice of therapeutic tactics at the outpatient stage. A clinical case with designated diagnosis is presented and analyzed as an illustrative example. Special attention was given to a complex evaluation of subjective, objective and diagnostic data, the significance of analyzing the development of dermatoses.Conclusion. Careful adherence to diagnostic algorithms will avoid iatrogenic errors and thereby improve the quality of medical care and the quality of life of dermatological patients.

Published: December 2023

Purpose: The objective of this study was to identify new links between Integrated Reporting (IR) and Intellectual Capital (IC) fields, useful for sustainability and climate change disclosures with ISSB standards.

Theoretical Framework: The literature that has integrated IC and IR fields has been developed, mainly from the IC research perspective, addressing a wide range of thematic specializations that emerge when analyzing the research areas.

Design/Methodology/Approach: We developed a Structured Literature Review (SLR) of articles indexed in Scopus, which allowed us to build a specific analytical framework from emerging categories; we rely on AtlasTi and VOSviewer software.

Findings: We found that the literature converges towards the following research areas: Reviews and reflections on the IR framework as a means for IC disclosure; Proposals to improve the IR framework and IR disclosures through IR; The IR framework and definition, measurement, and management of IC within organizations; disclosures of CI in contexts of practical adoption of RI; Disclosure of IC through IR, its determinants, and effects.

Research, Practical & Social Implications: We identified the need to advance research under a performative approach, research on stakeholder satisfaction by revealing IC through IR and the relationship of IC with information related to sustainability in the new ISSB context. The paper identifies previously unexamined connections between IC and IR and proposes future avenues of research.

Originality/Value: This study raises the need for increased policy research to define a common language for presenting comparable IC information in ISSB sustainability reports. In addition, studies are needed to help identify IC information, other IR capital and metrics, which could represent material information for investors to assess sustainability-related risks and opportunities.

This article reported design of FBG Sensor layered by 2D Graphene Material. In this research, the FBG was coated with single layer graphene material, then the outher FBG has been coated with Aluminium, Chromium Oxide, PMMA, and Silica. The finite element method was used to analyze the profile of each coated-FBG with a thickness of 20 µm. Furthermore, the sensitivity of each designed coated-FBGs for the temperature measurement was calculated in the range of 25 oC – 300 oC. Design and analysis of coated FBG found that the FBG coated with graphene then layered by PMMA material has the highest sensitivity of 406.4 pm/℃. Although the sensitivity was 395.73pm/℃ for PMMA material. It was followed by Aluminium coating material which yields the sensitivity of 71.367pm/℃. The Silica and Chromium oxide yield the same sensitivity of 13.73pm/℃. Furthermore, the simulation results shows that the design of coated FBGs with a Gaussian apodization has the narrowest FWHM width of 1.3 nm. While the Tanh and Uniform apodization yield FWHM width of 3.724 nm and 3.732 nm respectively. Certainly, the best FBG design for high temperature sensor was proposed by FBGs coated by graphene and layered with PMMA material with Gaussian apodization

Published: December 2023

Formulation of the problem. Modern research on the phase transformations modeling in low-alloy steels allow solving the problem of phase transformations quantitative determination for a given chemical composition of steel and different cooling rates. However, the possibilities of available universal software products for the complex alloy steels analysis are limited. The impossibility for users to integrate their own subroutines according to the phase transformation diagrams is their main disadvantage. Purpose of research. Modeling phase-structural transformations during cooling of complex-alloy steels taking into account the formation of all structural components, in particular residual austenite. To research, steels 25Cr2Mo1V and 38CrNi3MoV and existing analytical models were used, which were adapted to carry out the relevant calculations. Results. A new method for modeling phase-structural transformations during cooling of alloy steels is developed. Structural diagrams depending on the rate of continuous cooling are constructed for the investigated steels. For the first time, the amount of residual austenite is taken into account according to the developed method. Under developed method thermokinetic diagrams of investigated steels austenite transformation are constructed. According to the diagrams, the decay of austenite steel 38CrNi3MoV begins at lower temperatures compared to steel 25Cr2Mo1V. Steel 25Cr2Mo1V, with continuous cooling at a rate of 1.0 °C/s (conditions close to natural air cooling), consists of 18 % ferrite, 1 % pearlite, 80 % bainite and 1 % residual austenite. Steel 38CrNi3MoV cooled at a rate of 1,0 °C/s consists of 2 % ferrite, 47,5 % bainite, 50 % martensite and 0,5 % residual austenite. It is shown that the calculated data correlate well with practical results at the conditions of natural air cooling.

Published: December 2023

Purpose of research. Investigation into crack initiation features in heterophase inclusions of the “phase side by side” type during steel deformation. Methods. Destruction of various types heterophase inclusions is investigated during the deformation of samples from steels 08Ti, 08Al, 12MnSi, 08unk, 09Mn2Si, 08GSiAlTiV in the temperature range 20...1 200 °С. Samples of 08Ti and 08Al steels are subjected to tension, compression and bending, steel HB-57 − to tension and compression, steel 08unk, 08Cr, ATs45X ,ATs18XGT − to tension in vacuum at temperatures of 20...1 200 °С on experimental settings with special grips, which motion speed was 20 mm/min. Methods of investigation – petrography, X-ray microanalysis and optical microscopy were used. Results. It has been found that the diversity of phases composing the heterophase inclusions of the “phase side by side” type leads to their different behaviour under plastic deformation. The microcracks nitiation occurs along the internal interphase boundaries. Depending on the plasticity level of the phases composing the inclusion, these cracks can be brittle or ductile, which is also related to the effects of the deformation temperature. The features of microcracks initiation for different combinations of heterophase inclusions plastic and non-deformed phases of the “phase side by side” type are analysed. The interaction between heterophase inclusions of the “phase side by side” type and the steel matrix during deformation is discussed. Scientific novelty. The features of microcrack initiation related to heterophase inclusions of “phase side by side” type with different combination of brittle and plastic phases during steels deformation in a wide temperature range is determined. It was found that the microcracks initiation and spreading within inclusions “phase side by side” type occurs both in phases and along internal interphase boundaries. It is shown that the critical degrees of samples deformation, at which significant microcracks along the internal interphase boundaries occur, depend on the temperature and the inclusion phase. The critical degrees of samples deformation, upon reaching which significant microcracks occurred along the internal interphase boundaries, depended on the temperature and the nature of the “phase side by side” inclusions. The values of the critical degrees of deformation determine the level of cohesive strength of the internal interphase boundaries of the heterophase inclusions “phase side by side”. Practical significance. The use of obtained results will make it possible to develop technologies for producing steels with regulated types of heterophase non-metallic inclusions. This will substantially improve their technological and performance characteristics and prevent the various defects formation in the steel pressure treatment and the products operation.

Published: December 2023

Formulation of the problem. Currently, biosoluble materials are widely used for the manufacture of implants, among which the most promising are magnesium alloys. Magnesium is a natural element of the body. It is contained in bone and muscle tissue and involved in various metabolic processes. In addition, magnesium and its biocorrosion products have excellent biocompatibility. The main advantage of magnesium alloys is the positive effect magnesium has on the human body, but their quality is not satisfactory for use in the human body. Improved refining and modification processes of liquid melt can increase the properties of magnesium alloys. Purpose of research: to investigate and test various carbonaceous materials for refining and modifying magnesium melt. Method. Optical microscopy, application of standard techniques for determining the mechanical properties of magnesium alloy and special techniques for determining the refining and modifying ability of various carbon-containing materials. Results. The technology of cast magnesium alloys modification for Mg – Zr − Nd system by dispersed graphite powder is proposed. It is shown that the optimal carbon additive in the quantity of 0,05…0,1 % improves the mechanical properties due to grain grinding and additional strengthening of structural components. A complex filter containing equal quantity of magnesite, graphite and limestone is proposed. It provides an increased level of melt refining to obtain high quality casting. It is shown that the use of a complex carbon-containing filter provides not only efficient melt refining, but also its additional modification. In alloy structure the increased quantity of intermetallic γ-phase is observed, that provides increase the microhardness of alloy structural components and promotes increase of its physical-mechanical characteristics. Scientific novelty. The structure and properties of cast magnesium alloy for Mg –Zr – Nd system during modification with dispersed graphite powder and its filtration through carbon-containing materials are investigated. Practical significance. The developed complex technology for processing the liquid melt of magnesium alloys for the Mg – Zr − Nd system allows to increase the yield of suitable casting and improve its quality.

Published: December 2023

Purpose. The aim of the work was to analyze the features of the destruction of the inclusion − matrix interphase boundaries under aggressive influences and in the process of wear as a result of the degradation of their structure. Methods. The samples of steels 08, R7, ShKh15 were tested for low-cycle fatigue in air and in corrosive environments (1…5 % aqueous solution of NaCl and 2…1 % aqueous solution of H2SO4). A test method was used to test the tendency of steels to stress corrosion cracking on an IM-12 installation. Fatigue strength tests were carried out on an NU machine. Samples of steels 08kp, 08Yu, 08GSYuTF, ShKh15, R7, M74 were exposed to holding in an atmosphere of hydrogen for 2 h at of 650 and 1 100 °C, the pressure 5 and 10 MPa. The features of the wear of the rolling surface of railway wheels (steel R7), which have worked for 5 years under a passenger train, have been investigated. Research methods: metallographic ("Neophot-21"), electron microscopic ("JSM-35"), petrographic. Results. The features of the fracture of the interphase inclusion − matrix boundaries under various thermal-deformation and aggressive actions are investigated. The role of inclusion − matrix boundaries in the formation of cracks of fatigue, fatigue-corrosion and hydrogen origin is considered. Scientific novelty. It is shown that under the influence of aggressive media and cyclic stresses, the structure of the inclusion − matrix interphase boundaries degrades, which is associated not only with the accumulation of interfacial stresses, but also with the facilitation of the penetration of surfactant atoms from the environment along these boundaries. As a result, fatigue-corrosion destruction of the inclusion − matrix boundaries occurs, and the effect of an adsorptive decrease in their strength is manifested. Practical significance. The research results can be useful in the development of methods of targeted influence on non-metallic inclusions and inclusion − matrix boundaries in various types of steel processing and the operation of steel products.
MATHEMATICAL MODELING OF HARDNESS OF CAST IRON ROLLS PERFORMANCE ЛПХ17НМдц
Authors: Mospan A. V. 
Published: December 2023

Introduction. The technology of manufacturing sheet rolls is complex. The formation of their working layer is influenced by many parameters due to the standard technology of their manufacture. The service properties of rolls and quality of rolled metal largely depend on it. Heat treatment (annealing) is used to improve the properties of the rolls and to minimize residual stresses. Therefore, the study of the impact of heat treatment on the quality of cast iron sheet rolls using non-destructive methods is an urgent task of the metallurgical industry. Materials and methods. The influence of heat treatment on the hardness of cast iron rolls of ЛПХ17НМдц in the working layer (from 0 to 160 mm) was studied. The hardness values in the working layer of the rolls before heat treatment ranged from 47 to 49 HSD. After heat treatment, the hardness values increased significantly and varied from 72 to 75 HSD, which meets the requirements of ТУ У 14-2-1188-97. The metal matrix of the lower treph of the roll before heat treatment consisted of perlite cast iron microalloyed with chromium and nickel, consisting of perlite (81… 85 %), cementite (12…16 %), spherical graphite (2…3 %). After heat treatment, the structure of the bottom of the roll barrel was as follows: Chromium carbides + sorbitol tempering + Austenite ~ 7 %. The results of the experiment. At the initial stage of research with the use of expert evaluation, the analysis of the influence of the chemical composition of the rolls on their mechanical properties was performed using the developed author's software product (Yu.I. Dubrov, V.M. Volchuk, F.V. Kriulin). This is an important stage of research, because the size of the rolls and their chemical composition largely depends on the choice of heat treatment modes. Mathematical models are obtained by comparing the values of hardness at the reference points of the working layer of the roll barrel and the distance from the barrel surface. Mathematical models describe the effect of heat treatment on the hardness of the working layer and have satisfactory correlation coefficients R² = 0,72 (before heat treatment) and R² = 0,87 (after heat treatment). Conclusions. The change in the hardness of the rolls in the working layer before and after heat treatment, which is described by mathematical models using expert estimates, has been studied.
APPLICATION OF EXPERIMENTAL PLANNING METHODS IN EVALUATION OF СТ3ГПС STEEL QUALITY ASSESSMENT
Authors: Abakumova К. А. 
Published: December 2023

Introduction. Low-carbon low-alloy steels are widely used in construction. Therefore, despite the existence of a significant number of methods and ways to assess their quality criteria, the task of operational forecasting of these criteria is urgent. Difficulties in predicting the quality criteria of metal products from steels lie in the complexity of the technology of their production. If the parameters of the technology deviate from the normative documents, the properties of the material can differ significantly. In this regard, it is proposed to apply the method of experimental planning to estimate the tensile strength of low-carbon steel. Materials and methods. Samples of steel of ordinary quality Ст3Гпс made of a circle with a diameter of 24 mm were studied. The chemical composition of steel and its strength indicators varied within the normative documents in accordance with ГОСТ 380 and ДСТУ 2651. In the state of factory supply, the steel structure was ferritic-pearlitic. The content of the pearlite component, depending on the amount of carbon in the steel ranged from 11,2 to 17,6 %, the remaining fraction fell to ferrite. The results of the experiment. At the first stage of research the analysis of influence of each chemical element of steel on limit of its durability was carried out. To this end, with the help of the program "Expert", implemented on a computer, obtained one-factor models of strength forecast. In the second stage of research, the number of rows was reduced from 32 to 16 by implementing the matrix of experimental planning using the technique of small replicas. This approach significantly reduces the cost of experiments. The obtained multifactor (X1…X5) model for predicting the strength limit of steel St3Gps is adequate according to Fisher's and Cochren's criteria. According to Fisher's criterion, the coefficient of convergence of the results was 1,029 with a critical value of 2,400. The model is also adequate according to the Cochren test of 0,335 with a critical value of 0,547. At the third stage of research, based on the results of the analysis of the coefficients of the multiparameter model, histograms of complex assessment of the influence of chemical composition elements on the strength of steel are constructed. Conclusions. An adequate model for predicting its strength and histograms of the effect of its chemical composition on Ст3Гпс Steel was obtained. It makes sense to use the obtained results for the operational forecast of the strength of low-carbon steels in the state of factory delivery.
