Stations of the Publicum Portorium Illyrici are a Strong Predictor of the Mithraic Presence in the Danubian Provinces: Geographical Analysis of the Distribution of the Roman Cult of Mithras
Authors: Chalupa Aleš , Glomb Tomáš , Sarkisjan Juraj 
Published: November 2024

Abstract
The article examines the relationship between the Roman cult of Mithras and members of the publicum portorium Illyrici, the Roman customs office active in the Danubian provinces, who have been discussed in previous research as potentially important carriers of this cult. To investigate this relationship and its extent, spatial proximity analysis is performed with respect to documented portorium stations and confirmed Mithraic finds. For comparative purposes, the spatial proximity between portorium stations and finds relating to other selected Graeco-Roman deities was also examined. On the basis of the results of this analysis, it is possible to conclude that Mithraic finds are located significantly closer to customs stations than those of other Graeco-Roman deities (with the exception of Jupiter, the main Graeco-Roman god) and that the presence of a portorium station strongly predicts the presence of a Mithraic cult at a given site or in its immediate vicinity, especially in the Western cluster of portorium provinces. Thus, in a nuanced form and using a quantitative method of geographical analysis, the study supports previous conclusions about the importance of portorium officials as a social group significantly involved in the spread of the Roman cult of Mithras in the Danubian provinces.

Abstract
This study explores the effect of integrated superelastic shape-memory alloy fibers (SMAFs) on the mechanical performance of engineered cementitious composites (ECCs). Various SMAF configurations – linear-shaped SMAFs (LS-SMAFs), hook-shaped SMAFs (HS-SMAFs), and indented-shaped SMAFs (IS-SMAFs) – with diameters of 0.8 and 1.0 mm were incorporated into ECC matrices, and surface texturization was achieved through abrasive paper treatment. Their mechanical properties were assessed through single fiber pullout tests on ECC mixtures containing 1.5 and 2.0% polyvinyl alcohol (PVA), subjected to both monotonic and cyclic loading conditions. Qualitative analysis, employing scanning electron microscopy, demonstrated that the IS-SMAF configuration provided superior mechanical interlocking and fiber–matrix adhesion, with a distinct flag shape observed during tensile testing. Quantitative data indicated that IS-SMAFs significantly improved the tensile strength and pullout resistance, with slip distances of ≥5 mm and average pullout loads ranging from 263 to 403 N. LS-SMAFs demonstrated better performance compared to HS-SMAFs and LS-SMAFs in terms of tensile and pullout characteristics. Additionally, ECCs with increased PVA content exhibited enhanced withdrawal performance. Thermogravimetry analysis and X-ray diffraction provided insights into the high-temperature stability and crystalline structure of the composites. These results underscore the effectiveness of IS-SMAFs in enhancing ECC properties, offering significant implications for the development and optimization of high-performance composite materials in civil engineering applications.

Published: November 2024

One of the most significant changes the business world is currently experiencing is the progressive development and adoption of digital commerce. Taking into account the rapid development of web and Internet technologies, e-commerce is increasing volumes on a global scale and is being formed as a separate branch of the economy. Every year from 30 % to 70 % businesses of all countries (regardless of their level of development) are moving to the online environment. This is especially true for business entities that carry out trading activities.
The object of the study is the process of integrating multichannel sales in retail trade in Ukraine, with a focus on its impact on the efficiency and competitiveness of enterprises in the market. The problem under consideration is to determine the most effective methods and strategies for implementing e-commerce in the Ukrainian economy, which is under the influence of martial law and other socio-economic factors.
The main results of the study show that the integration of online and offline sales channels significantly increases business productivity. It was found that the use of omnichannel platforms can significantly improve customer interaction and increase sales. In particular, the analysis showed that properly integrated sales channels can increase the efficiency of enterprises by 20–30 %.
These results can be explained by the high level of adaptability of Ukrainian companies to new technologies and their ability to quickly integrate digital platforms into their business processes. The study also confirmed that businesses that actively use omnichannel strategies achieve higher levels of efficiency and competitiveness.
In practice, these results can be applied to the real-life conditions of Ukrainian retailers. This is especially true for small and medium-sized enterprises seeking to increase their market presence through the introduction of modern technologies and the integration of various sales channels. Using the data obtained will allow companies to optimise their business models, develop effective marketing campaigns and improve customer interaction. The findings can also be applied to the analysis of omnichannel retailing and digital commerce in other countries at different stages of retail development. This study also provides practical recommendations that may be useful for international companies and academics interested in improving retail performance.

The object of research is the process of granulation of mineral fertilizers by applying rolling and pouring methods, as well as in fluidized and suspended layers with active hydrodynamics of flows. It is noted that the development of the main technological stages of the production of granulated fertilizers should be aimed at improving the hardware design of granulators, establishing the most rational regime and technological parameters of the process in order to increase its efficiency and reduce energy costs. It is noted that the main indicators of the efficiency of granulation plants using heat are economic costs, exergy losses, as well as reduced costs. The method of exergy analysis for the assessment of energy costs for granulation processes in different types of granulators is presented, which allows to justify the choice of rational parameters of the specified processes, taking into account energy costs and equipment efficiency. Equations are presented for determining the amount of exergy of material flows and exergy losses caused by heat exchange at finite temperature differences of technological flows at the entrance to the device and at the exit from it. The equation for determining the exergy efficiency, which characterizes the energy efficiency of the technical system, is presented. The smaller the temperature difference for the technological flows at the exit from the device, the smaller the exergy losses, the higher the value of the exergy efficiency. and, accordingly, the device will have greater energy efficiency. An exergy analysis of granulation processes in granulation towers without a cooler, in granulation towers with a cooler, fluidized bed devices and multi-stage (shelf) devices was carried out. The analysis showed that the exergy efficiency for the specified granulation plants is equal to: 64 %, 71 %, 32 % and 96 %, respectively. The obtained research results can be applied in production conditions where granulation towers and devices of fluidized or suspended layers are used. Enterprises that plan to reduce energy costs and increase the environmental safety of their technological processes can implement improvements based on the proposed methods and equations. The application of research results will contribute to the selection of more rational indicators of the granule production process, which will increase the productivity and quality of the final product.
Application of probabilistic and stochastic models and data mining for forecasting the contingent of old age pension recipients in the context of systemic uncertainty
Authors: Zarudnyi Oleksii , Koval Roman 
Published: November 2024

The object of the research is mathematical models for forecasting the contingent of pension recipients in conditions of uncertainty caused by both the reform of the pension system and the impact of armed aggression. Based on the study of statistical information on the structure and dynamics of the contingent of pension recipients, an approach to uncovering systemic uncertainty in the task of forecasting the contingent of pensioners is proposed. This work is part of a study of the application of data mining methods of intellectual data analysis and mathematical modeling in information technology intended for use in the pension system. The main focus of this work is on forecasting the dynamics of the contingent of pension recipients by age, in particular, forecasting the number of newly appointed pensions. The difficulty of forecasting the contingent of pension recipients, in particular by age, is connected with the fact that it is necessary to ensure the representativeness and variability of data sets. In addition, it should be taken into account that a significant number of factors must be included in the model in accordance with the requirements of regulatory documents. Another problematic issue is that the time series of the investigated indicators, such as data on the insurance experience of insured persons (based on the results of a sample survey), may contain significant (more than 40 %) gaps that can be filled only on the basis of primary (paper) documents. Therefore, the input data sets are formed with assumptions about the probability of the accumulation of insurance experience in various groups of insured persons. The paper proposes an analytical toolkit based on the use of probabilistic and statistical models in the form of Bayesian networks, intended for use in specialized decision-making support systems of the Ukrainian pension system. In the course of the study, a number of numerical experiments were carried out, in which the correctness of the proposed method was investigated. The proposals presented in the paper will improve the stability of the pension system of Ukraine, including through a more accurate definition of the dynamics of the contingent of pension recipients and, accordingly, the costs of pension payments. The proposed models and methods can be used as part of decision-making support systems of state and public administration bodies to analyze the results of reforming the pension system.

The object of the study is heavy metals in the Shatt Al-Arab River. Shatt Al-Arab River is considered one of the most important internal rivers in Iraq due to its multiple economic and social importance. In addition, this river has an important strategic location. Despite its importance mentioned above, the Shatt Al-Arab River suffers from various wastes from many and varied sources, which have directly affected the quality of its water and consequently the quality of the community of living organisms that live in it. Levels and distribution of certain heavy metals, Cd, Cu, Fe, Mn, Ni, and Pb, were determined in core sediments from Southern Iraq Waterways. Six sites were investigated, two in the lower reaches of Al-Hammar Marsh, 1) El-Barka, 2) El-Garmah, and four sites along Shatt Al-Arab River, 3) Al-Ashar, 4) Abu Al-Khaseeb, 5) Abu Floos Port, and 6) Al-Faw. The results indicate that Al-Faw station was distinguished by the fact that the highest values of heavy elements were obtained at this station and all depths, except Cd at Al-Ashar station at a depth of 25 cm (26.1375 μ/gm), Cu at a core depth of 50 cm (4.9635 μ/gm), Ni at a core depth of 25 cm (5.2483 μ/gm), and surface water (2.9021 μ/gm) and Pb in surface water at Abu Floos Port station (3.5001 μ/gm). The lowest concentrations of heavy elements for Cu, Mn, and Ni are in all depths of core sediments. Other elements, Cd, Pb, and Fe, were higher; on the other hand, higher levels of concentrations for all studied heavy metals were recorded at a depth of 100 cm. Iron was the highest in all depths of core sediments.

The object of research is the process of regulating power imbalances due to automated control of steam turbine parameters. The work solves the problem of minimizing power imbalances in the electric power system by developing a model of automated control of steam turbine parameters. This will ensure high-quality regulation of frequency and power, increase the efficiency and stability of the electric power system, and provide a new management method for reliable power supply to consumers.
The paper analyzes existing models and methods of power imbalance regulation, develops a dynamic model of automated control of K-300-240 steam turbines, which includes a mechanical-hydraulic system, a steam boiler and a steam superheater. As a result of the study, an improved power regulation method was proposed, which ensures efficient operation of the electric power system. The evaluation of the effectiveness of the regulation of imbalances was carried out on the basis of the proposed criterion of the efficiency of electricity supply and consumption, which is based on the convolution of partial criteria into the general criterion of the efficiency of electricity supply. The following criteria were proposed as partial criteria for electricity supply and consumption: volume criterion, quality criterion, and electricity supply efficiency criterion. The research results indicate the need for a reserve on each steam turbine in the amount of 10 % of its nominal power, which is explained by the assessment of the efficiency of electricity supply among the considered modes of operation of the systems. The presence of a power reserve on each steam turbine in the amount of 10 % of their nominal power ensures the most efficient power supply within the considered modes of operation of the power system, taking into account disturbances and as an imbalance of power generation and power consumption. The obtained research results can be applied in the strategy of primary regulation of power imbalances in the electric power system, thanks to the creation of a power reserve in the amount of 10 % of the nominal power on each steam turbine, and the organization of automated control of steam turbine parameters.

Published: November 2024

The object of the research is regulatory support for the use of natural mineral waters and spring waters for the preparation of food for infants. Along with drinking water, natural mineral water is used for the preparation of food for infants, which is more protected from contamination. Currently, there are no approved safety parameters for natural mineral waters and spring waters in Ukraine, as well as requirements for markings on packaging or labeling that relate to the suitability of these waters for feeding infants. In this work, based on the results of the analysis of the current legal documents of European countries (Poland, Bulgaria, the Czech Republic, France, Germany) on the use of natural mineral waters in the preparation of food for infants, the indicators of the safety and quality of natural mineral and spring waters in Ukraine in the preparation of food are substantiated food for infants. Because of the specific physiological needs of children at an early age, water for cooking is an important factor in their normal psychophysical development. Water for preparing infant food must meet stricter criteria for total mineralization (suggested: ≤500 mg/l), the content of certain macro-components, nitrites (suggested: ≤0.1 mg/l), nitrates (suggested: ≤10 mg/l), ammonium (suggested: ≤0.1 mg/l), fluorides (suggested: ≤0.7 mg/l), sanitary and microbiological indicators (suggested normalization of the indicator of the total microbial number in the finished product). The peculiarities of the technology of industrial packaging of natural mineral waters and spring waters for the preparation of infant food are outlined. These waters are packaged only non-carbonated, without the addition of any preservatives or disinfectants. Packaging of these waters should take place near water points, which should be reliably protected from biological and chemical contamination. The obtained results can be used for the development and approval of a normative legal act in Ukraine on the regulation of the use of natural mineral waters and spring waters for the preparation of infant food.
Deliberative Democracy in Practice: Handbooks on Commissioning, Facilitating, and Evaluating Deliberative Processes
Authors: Massie Joanna 
Published: November 2024

Governments seeking to address declining trust, increasing polarisation, and greater complexity in government policy have increasingly turned to democratic innovations to engage citizens. For practitioners and academics alike, the term ‘deliberative wave’ has become shorthand to describe the increased popularity of these tools and the emergence of a field of study that has the potential to revitalise citizen-state relationships. The practical handbooks reviewed here present a mosaic of tools, resources, and lessons from experience to ensure the successful commissioning, organisation, and facilitation of deliberative mini-publics (DMPs). They each provide valuable insights based on years of expertise developed running processes with publics (Enabling National Initiatives, Facilitating Deliberation) or consolidating a vast array of international experience (Assembling an Assembly, Innovative Citizen Participation, EvaluationGuidelines, Eight Ways to Institutionalise). In this review I reflect on definitions of deliberation; why these guides argue DMPs are important; and the connection between deliberative democracy theory and practice.
