Published: February 2025

Abstract
Short-range wireless DC-to-DC power transmission using a switched capacitor converter (SCC) for various voltage ranges is presented in this letter. In wireless power transfer (WPT) applications, the main factors to consider are the target’s distance from the source coil and the voltage received at the load. In this work, the receiving voltage can be varied according to the application by selecting the voltage ratios (VRs) using the multiphase controller. The different VRs are selected using the Fibonacci series having the arbitrary value of (0, 1). A proposed circuit is designed and simulated using SIMULINK to validate the proposed WPT converter and to verify its transfer efficiency. The constituent blocks of the transmitter and receiver modules are designed, simulated, and examined for WPT. In many studies, step-up voltages are presented and discussed, but not the step-down WPT. This letter discusses the wireless power supply system with different step-down/step-up VRs, which can be used to supply auxiliary systems such as battery charging, audio systems, mobile phone calls, and general voltage regulators. The proposed converter with WPT provides high efficiency, voltage regulation, and target distances. The power of the proposed converter varies from 80 μW to 100 μW for the input voltages 12 V–24 V.

Abstract
Sustainable Enterprise Resource Planning (S-ERP) systems are essential for integrating sustainability into business operations and improving environmental, social, and economic performance for any organization. Nevertheless, the implementation of S-ERP systems is complicated and presents multiple challenges. The purpose of this review is to fill the knowledge gap by thoroughly analyzing the current status and utilization of S-ERP systems through an in-depth examination of existing literature to identify critical factors for successful implementation and offer guidance to support organizations in aligning sustainability goals with ERP systems. Employing a qualitative narrative review methodology, this research examines literature from major academic databases and focusing on studies published between 2000 and 2024. The research identifies key factors crucial to the successful integration of S-ERP systems, such as comprehensive strategic planning, efficient data management, strong managerial commitment, interdisciplinary expertise, and a carefully structured implementation plan. These factors not only streamline the initial deployment process but also ensure the system’s flexibility to accommodate evolving sustainability goals and technological advancements. The study emphasizes the importance of a systematic approach to S-ERP adoption, with a focus on aligning with the organization’s sustainability objectives and structural context to optimize benefits while minimizing risks. This research provides actionable guidance for organizations seeking to implement S-ERP systems effectively, offering strategies to navigate both the opportunities and challenges in this rapidly evolving field. It also delivers critical insights for researchers, industry practitioners, and organizational leaders, equipping them with the knowledge needed to enhance sustainability efforts through the adoption and optimization of S-ERP systems.

Abstract
Development is an integral part of research, since the study of specifics and characteristics in such a unique topic as the quality of processed products cannot be done without extraordinary equipment, fixtures and a laboratory. Laboratory equipment has been created that combines all hardware aspects of the development of the quality of processed products, where it analyzes the quality of workpieces that depend on the processing technology. However, this depends largely on the technological system used. The paper includes measurements, data acquisition and back-checking of the logic of the study of grinding operations. In the introduction, it must be shown that the correct selection and strength characteristics of the tool associated with the cutting mode of grinding determine the accuracy and quality of the surfaces of the ground part. The impact on the service life of the grinding tool was also monitored. The 4th partial result is also the knowledge that the correct selection of the tool characteristics and cutting mode predicts the quality of the workpiece surface. The operating conditions of the manufactured parts significantly affect the operating values of the production parameters. By appropriate diagnostics in the research process and precise measurements using sensitive sensors, deviations can be minimized. Without this apparatus, it is possible that deviations increase significantly during the operation of the technological system. The size of the deviation during grinding is explained in practice by the presence of vibrations in technological processes. They cause instability of the parameters of the technological system. To stabilize the quality indicators, a mathematical apparatus was also used, which takes into account changes in the technological regime. They are determined by designing adverse conditions, e.g. restoration of the cutting properties of a worn grinding wheel. Therefore, its replacement is logically carried out earlier than its replacement is planned.
Evaluating Supply Chain Risks in The Moroccan Automotive Industry: A Multi-Criteria Decision-Making Approach
Authors: Kayouh Nabil , Dkhissi Btissam 
Published: February 2025

Abstract
Supply chain resilience is a critical determinant of success in the automotive industry, particularly in emerging markets like Morocco. This research employs a comprehensive approach to identify and prioritize external logistical risks threatening automotive supply chains in Morocco. Through interviews with logistics specialists of multinational automotive companies, we utilized the fuzzy Analytic Hierarchy Process (AHP) and the fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to assess the weights of evaluation factors and rank the identified risks, respectively. Our findings reveal that catastrophic events in the factory, extreme weather conditions, and workers’ strikes/labor union issues are the top three risks posing the greatest threat to supply chains in Morocco. Additionally, challenges such as agitated political situations, high maintenance costs, and infrastructure limitations demand attention to enhance supply chain resilience. This research contributes to the understanding of supply chain risk management in emerging markets and offers practical insights for industry practitioners and policymakers aiming to fortify automotive supply chains in Morocco and similar contexts.
Legitimation Crisis of Capitalism in Romania: Social Dynamics and Ideologized Knowledge Production
Authors: Gog Sorin 
Published: February 2025

Abstract
This paper aims to investigate the discrepancy between the disaffected public perception of capitalism in Romania, as it emerges from past and current sociological survey data, and the construction of Romanian society as a social totality within mass media, the political sphere, and the social sciences. My argument is that these three spaces of knowledge production function according to ideologized criteria meant to stabilize capitalism in Romania and generate a distorted framework of understanding past and current social dynamics2.
Do Perceptions About the Causes of Poverty and Wealth Shape Attitudes Towards Progressive Taxation? An Exploratory Analysis for 2021 Romania
Authors: Dragoman Diana , Raţ Cristina 
Published: February 2025

Abstract
Lying at the backbone of European welfare states, taxation is both an enabler of redistribution and a predilect means of fiscal welfare. Among Central and Eastern European countries, Romania was an early adopter of flat rate taxation two decades ago, in 2004. As Kovács (2022) convincingly argues, in terms of net wages this shift led to less revolutionary outcomes than expected; however, it clearly diminished the tax burden for middle and higher wages, while those on lower wages paid gradually bigger taxes, as deductions eroded. By 2021, opinion polls indicate that three quarters of Romanians show support for progressive income taxes (Friedrich Ebert Stiftung, 2021: 20). Which socio-economic and demographic factors shape this attitude? The present paper offers an exploratory analysis of the relation between perceptions about the causes of poverty and wealth and being in favour of progressive income taxes in one of the most unequal and impoverished countries of contemporary Europe.
The Path from Romania to the Italian Domestic Care Sector: The First Stage of the Decisionmaking Process on Labour Migration
Authors: Harabagiu Irina-Miruna 
Published: February 2025

Abstract
This paper aims to propose a multi-stage model for the decisionmaking process on labour migration that takes into account both individual agency and structural dimensions along political-institutional, economic, and social factors. While it is focused on the case of Romanian women’s migration to the Italian domestic care sector, it can be applied for the analysis of other types of labour migration too. From a historical perspective, Romania underwent major political, economic, cultural, and social transformations after 1989 and throughout the years of EU integration and membership, that influenced transnational labour migration. With the help of relevant population statistics and qualitative interviews with Romanian women working in Italy, I illustrate how the three structural dimensions contribute to the start of the individuals’ decision-making process on migration. The political-institutional dimension both enables a culture of labour migration and conditions or disinhibits the possibility of migrating abroad for work. Through a series of disruptions, the economic dimension creates distress, which brings certain individuals in a state of needing alternative solutions to ensure their livelihood. As they search for solutions, these people will be exposed to the option of labour migration. This exposure, however, takes place in the social dimension, which represents the aggregate of individuals’ social relationships. Finally, by assuming the roles of mentors and/or migration facilitators, social actors influence individuals to become aspiring migrants and to follow a migratory destination. Considering working abroad as an option (available, needed and possible) represents the first stage of a decision-making process that the individuals go through. At the end of it, the actors will become from aspiring migrants- novice labour migrants.

Abstract
This article explores how to improve operational performance in maritime ports by managing the flow of goods effectively. This study proposes an innovative approach based on Reinforcement Learning (RL), specifically the Monte Carlo Tree Search (MCTS) method, to address the restricted container relocation problem (RCRP). This method aims to determine an optimal sequence for container retrieval based on their respective priorities, in order to minimize the number of necessary relocations. By employing precise actions and a defined reward function, MCTS is guided towards the best possible solution. The efficiency and relevance of this method are demonstrated through various solved scenarios and compared to a literature-based approach using genetic algorithms. The results show that the MCTS approach is effective in addressing the complex challenges of goods flow management in maritime ports.

Published: February 2025

Abstract
Globally, over a billion people live with disabilities, facing significant challenges in accessing public transport, which impacts their autonomy, social participation, and economic status. Current research indicates that common problems include inadequate service in terms of destination, timing, and travel duration, as well as physical barriers at stops and the behaviour and proficiency of transit staff. These issues are exacerbated for those with visual impairments or mobility challenges, such as wheelchair users, who face even greater obstacles. This research emphasizes the necessity of an “enabling transport” environment that considers all aspects of travel for those with limited mobility. This includes the physical layout of pedestrian routes, the design of buildings, and the functionality of public transportation systems. Practical measures like aligning bus floors with pavements, as mandated in the European Union, and optimizing the deployment of accessibility equipment like pallets are discussed as essential for improving access. The authors propose a research methodology that employs a graph-based approach in combination with recurrent neural networks models to suggest most accessible pathways considering fleet availability, vehicle capacity and road quality of sidewalks. The approach includes a comprehensive case study in Riga, Latvia, utilizing data from local transport operators and crowdsourced information to assess and address physical barriers. This innovative application of deep learning on graphs aims to significantly improve the inclusivity and efficiency of public transport for people with disabilities. The study emphasizes the broader benefits of creating accessible environments that improve usability for all citizens, not just those with disabilities.
Zu Fragen der Polarität

It is proposed that an organic molecule can be characterised by a «property vector» of the following form:
E = ( D P Ha/Hd Ea/Ed La/Ld) [sqrt(energy/mole)] (1)
The terms of this vector show the ability of the molecule to attract other organic molecules: D: by dispersion forces and P: by the inhomogeneity of its electrical field. The remaining terms symbolise properties in which forces between two molecules exist only if one of them is an acceptor, the other a donor: Ha/Hd: interaction by displacement of a nucleus of the donor towards the acceptor («hydrogen bridge»), Ea/Ed: by displacement of «one» electron in one molecule towards the other («charge transfer») and La/Ld: Lewis acid-base type interaction.All terms beside D should be small and in any case not greatly exceed the magnitude of sqrt(RT). In this case a linear combination of the interaction forces (LCID) is admissible as approximation to calculate the resulting force as shown by the equations (2), (3), (4) and (5). Note that P is defined to represent an additional effect to D furthermore H, E and L represent additional effects over D + P.Existing polarity scales are discussed in the light of the method of LCIF in a qualitative manner.

Рассмотрены методологические аспекты и общие принципы организации регионального экологического мониторинга. Авторами отмечается, что основные положения и цели программы глобальной системы мониторинга были сформулированы в 1974 г. на Первом межправительственном совещании, на котором первоочередной задачей была признана организация мониторинга загрязнения окружающей природной среды и вызывающих его факторов воздействия. При этом говорится, что наибольший интерес для крупных городов России представляет региональная подсистема, основанная на следующем принципе: выбор ее состава и структуры осуществляется, исходя из физико-географических, гидрометеорологических и иных особенностей территории с учетом уровня и масштабов развития промышленного производства, автотранспорта, состояния городских и сельских поселений и др., и направленная на решение следующих задач: оценку состояния среды с целью «инвентаризации» природных и природно-техногенных территорий и объектов в масштабах всего региона; определение «горячих точек» на карте региона – промышленных объектов с высоким уровнем выбросов (сбросов) загрязнений; решения проблем управления отходами производства и потребления.
The article deals with methodological aspects and general principles of regional environmental monitoring. The authors note that the main provisions and objectives of the program of the global monitoring system were formulated in 1974 at the first intergovernmental meeting, at which the organization of monitoring of environmental pollution and its causing factors was recognized as a priority. At the same time, it is said that the regional subsystem based on the following principle is of the greatest interest for large cities of Russia: the choice of its composition and structure is based on physical and geographical, hydro meteorological and other features of the territory, taking into account the level and scale of development of industrial production, motor transport, the state of urban and rural settlements, etc., and aimed at solving the following problems: assessment of the state of the environment for the purpose of «inventory» of natural and man-made territories and objects throughout the region; definition of «hot spots» on the map of the region – industrial facilities with high emissions (discharges) of pollution; solutions to the problems of production and consumption waste management.

O livro visa analisar o acesso a direitos e políticas públicas para deslocados internos ambientais por barragens na Paraíba entre 2019 e 2024. Realizado pelo Núcleo de Estudo e Pesquisa sobre Deslocados Ambientais (NEPDA) da Universidade Estadual da Paraíba, a pesquisa investiga a situação de deslocados, líderes comunitários e autoridades em diversos municípios. A construção e o rompimento de barragens têm causado deslocamentos, com a região Nordeste enfrentando desastres significativos. Na Paraíba, 396 das 638 barragens apresentam alto risco de desastre. Apesar da previsão de um marco legal para proteger os direitos desses deslocados, sua aplicação tem sido ineficaz. A coleta de dados incluiu pesquisa bibliográfica, entrevistas e observação em locais afetados, revelando que muitos deslocados não são reconhecidos oficialmente e carecem de proteção internacional.
