SOCIAL INTEGRATION OF INTERNALLY DISPLACED PERSONS IN UKRAINE: PERCEPTIONS FROM IDPS VS. THE HOST POPULATION
Publication Name: Economics and Sociology
Publication Date: 2024-01-01
Volume: 17
Issue: 4
Page Range: 61-81
Description:
The social integration of internally displaced persons in Ukraine is analysed based on 5 dimensions of social integration: economic, political and religious, social, socio-psychological, and integration into cultural and sports life. The study was conducted using a nationally representative sociological survey of internally displaced persons (500 respondents) and the population of host communities (850 respondents). Differences in the perception of integration are investigated based on comparing the assessments of internally displaced persons and the population of the host communities. The highest integration is obtained in the socio-psychological, political and religious dimensions. The lowest level is in integration into community life. An important empirical result is the lower scores of the population compared to IDPs in almost all 21 criteria for integration. This is an indirect sign of significant social distance and lower readiness of the population of host communities, compared to IDPs themselves, to seek opportunities for interaction. The cluster analysis reveals the links between the most significant factors for successful integration: mutual respect between IDPs and local residents, tolerance, active engagement in local policy-making, and support for country defence. The most crucial obstacles to successful integration according to IDPs’ judgements are lower possibilities compared to the local population in participation in projects aimed at local communities’ development (65,3%), entrepreneurship development (60% of responses), and participation in decision-making regarding the community development (55,9%). The findings are important for developing policies to reduce the social exclusion of IDPs in areas where integration is below average.

Study of the antifungal effect of a copper-containing foliar fertilizer
Publication Name: Cereal Research Communications
Publication Date: 2021-06-01
Volume: 49
Issue: 2
Page Range: 337-341
Description:
Winter wheat (Triticum aestivum L.) is one of the most important arable crops. Copper-containing fertilizers are used in crop production to treat or reduce the negative effects of copper deficiency. Various copper compounds are also widely used as effective fungicide agents. The influence of a copper-containing foliar fertilizer prepared from a copper solution and sucrose had been tested on the yield and raw protein content of winter wheat in previous field experiments. In this work, we studied the antifungal effect of this particular foliar fertilizer in an in vitro trial, wherein the fungicide effect on growth and reproduction of specific plant pathogens, i.e., Fusarium graminearum and Drechslera sorokiniana, was evaluated with the agar well diffusion method. The results showed that doses of the foliar fertilizer corresponding to field applications of at least 1 kg ha−1 had antifungal effects, which were significant (P < 0.01) above the concentration level of 3337 mg L−1, corresponding to 2 kg ha−1 application, against both fungal pathogens. A linear correlation (r2 > 0.95) was found between copper concentration and fungicide efficiency in the concentration range studied. The fungicide efficiency of the foliar fertilizer was lower than that of the commercially available copper-oxychloride fungicide. The sole use of the foliar nutrient tested probably cannot replace fungicide treatments. However, in addition to its plant nutrition effect, its antifungal properties should also be taken into consideration.

Introducing the EPP house (topological space) method to solve MRP problems
Publication Name: Plos One
Publication Date: 2021-06-01
Volume: 16
Issue: 6 June
Page Range: Unknown
Description:
The problem of product and process planning analysed so far is how we can take advantage of our strategy in planning. Among the principles of manufacturing and service management concepts is that after planning demand, planning transformation is one of the key steps of integrated efficiency; it makes it possible to save costs that are not value adding and are not necessary from the customer's point of view. Currently, the methods of material requirements and capacity planning can be seen as classic solutions that are based on dependency relations between different resources, which can be dynamic in space and time. Measuring and recording capacities raise several problems in addition to the fact that our planning methods are not always satisfying. In the literature, the methods of material requirements planning or manufacturing resource planning (MRP) are not typically optimization methods, so they do not guarantee the best solution, and even if our planning methods were satisfying, several manufacturing restrictions (the time allowed, the complexity of the planning process, the lack of testing opportunities, etc.) could prevent us from reaching satisfying application. It is necessary to create a simple planning algorithm that can give the planner a greater degree of freedom and that would be simple and algorithmic in order to maintain continuous conscious control, putting an end to planning uncertainty and leading us to the best solution under the given conditions. The aim of our research is to introduce a novel, simple planning algorithm, similar to heuristic methods that eliminates the problem of defining the order quantity when applying traditional methods, which prevents us from determining in advance which method is desirable (causing unnecessary planning steps); computer- based solutions hide the causal relations of the methodology from the planner (causing unreliability uncertainty).

Script-Based Material and Geometrical Modeling of Steel–Concrete Composite Connections for Comprehensive Analysis Under Varied Configurations
Publication Name: Applied Sciences Switzerland
Publication Date: 2025-03-01
Volume: 15
Issue: 6
Page Range: Unknown
Description:
The behavior of steel–concrete composite structures is significantly influenced by the efficiency of the shear connections that link the two materials. This research examines the performance of stud shear connectors, with an emphasis on analyzing the effect of different geometric design parameters. A computational model was created utilizing Python 3.13 to enable thorough digital monitoring of the influence of these parameters on the structural performance of composite connections. Developed within the ABAQUS framework, the model integrates geometric nonlinearity and the Concrete Damage Plasticity (CDP) approach to achieve detailed simulation of structural behavior. Essential design aspects, including stud diameter, stud height, head dimensions, and spacing in both longitudinal and transverse directions, were analyzed. The Python-based parametric model allows for easy modification of design parameters, ensuring efficiency and minimizing modeling errors. The significance of stud diameter changes was analyzed in accordance with Eurocode standards and previous studies. It was found that stud length has a reduced effect on structural performance, particularly when considering the concrete properties used in bridge construction, where compressive failure of the concrete zone is more critical at lower concrete strengths. Additional factors, such as stud head dimensions, were investigated but were found to have minimal effect on the behavior of steel–concrete composite connections. Longitudinal stud spacing emerged as a critical factor influencing structural performance, with optimal results achieved at a spacing of 13d. Spacings of 2d, 3d, and 4d demonstrated overlapping effects, leading to significant performance reductions, as indicated by comparisons of ultimate load and force–displacement responses. For transverse spacing, closer stud arrangements proved effective in reducing the likelihood of slip at the steel–concrete interface, enhancing composite action, and lowering stress concentrations. Additionally, reducing the transverse distance between studs allowed for the use of more shear connectors, increasing redundancy and enhancing performance, especially with grouped-stud connectors (GSCs).

Mathematical Modeling of the Rail Track Superstructure–Subgrade System
Publication Name: Geotechnics
Publication Date: 2025-03-01
Volume: 5
Issue: 1
Page Range: Unknown
Description:
The “rail track superstructure–subgrade” system is a sophisticated engineering structure critical in ensuring safe and efficient train operations. Its analysis and design rely on mathematical modeling to capture the interactions between system components and the effects of both static and dynamic loads. This paper offers a detailed review of contemporary modeling approaches, including discrete, continuous, and hybrid models. The research’s key contribution is a thorough comparison of five primary methodologies: (i) quasi-static analytical calculations, (ii) multibody dynamics (MBD) models, (iii and iv) static and dynamic finite element method (FEM) models, and (v) wave propagation-based models. Future research directions could focus on developing hybrid models that integrate MBD and FEM to enhance moving load predictions, leveraging machine learning for parameter calibration using experimental data, investigating the nonlinear and rheological behavior of ballast and subgrade in long-term deformation, and applying wave propagation techniques to model vibration transmission and evaluate its impact on infrastructure.

Relationships between Shear Strength Parameters with Mineralogy and Index Properties of Compacted, Unsaturated Soils
Publication Name: Studia Geotechnica Et Mechanica
Publication Date: 2025-03-01
Volume: 47
Issue: 1
Page Range: 65-88
Description:
The objective of this study is to assess the influences of soil index properties, swelling parameters, and soil mineralogy on unsaturated shear strength parameters (φ', φb, c') of compacted expansive soils. The laboratory tests include the grain size distribution, specific gravity (Gs), Atterberg limits, swelling potential, X-ray diffraction, modified Proctor compaction, soil suction, and triaxial testing. MINITAB 19 statistical analysis software generates the tri-dimensional surface graphs. The values φ', φb, and c"are majorly influenced by water (%), Gs, and clay (%). φ"shows a strong correlation with free swell ratio (FSR), free swell index (FSI), and void ratio. φb demonstrates a strong relationship with liquid limit, plasticity index, and γd (dry unit weight). φ"and c"portray a moderate relationship with liquid limit, plasticity limit, and γd. φ"exhibits a moderate correlation with smectite (%) and plagioclase (%). φb describes a strong relationship with smectite (%) and a moderate correlation with plagioclase and K-feldspar (%). c"depicts a moderate correlation with smectite (%), K-feldspar (%), and plagioclase (%). The matric suction controls the behaviour of unsaturated soils. Nonetheless, the influences of soil index properties, swelling potential, and mineralogy on shear strength are not marginal. These findings provide a good insight into the behaviour of unsaturated expansive soils and contribute to enhancing geotechnical modelling.
