Estimating agricultural sustainability: a multidimensional approach to a farm-level assessment tool
Publication Name: Frontiers in Environmental Science
Publication Date: 2026-01-01
Volume: 13
Issue: Unknown
Page Range: Unknown
Description:
Introduction: In response to the growing demand for practical and robust sustainability assessment tools, this study introduces a new method for evaluating agricultural sustainability at the farm level. The tool relies on indicators covering environmental, economic, and mixed dimensions of sustainability. The mixed dimension integrates environmental, economic, and social indicators. Methods: Indicators were selected based on the literature and empirical data from Hungarian farms. From 61 initial indicators, three groups were formed through factor analysis and clustering. Results: The analysis revealed that environmental and economic factors contribute almost equally to sustainability scores, whereas the mixed dimension has a comparatively smaller impact. This suggests that immediate sustainability improvements might need to prioritize environmental and economic factors. The assessment tool allows the calculation of a complex agricultural sustainability index, which has been validated through case studies on Hungarian farms. Discussion: This study is presented as a methodological pilot project to develop and test a farm-level sustainability assessment tool for agricultural enterprises. The results highlight the practical applicability of the tool for farmers and policymakers, as it offers a transparent, easy-to-use method for identifying sustainability strengths and weaknesses at the enterprise level. Limitations include a small, region-specific sample, which may restrict broader applicability. Additionally, there are challenges in integrating multidimensional indicators. Future research should focus on expanding the dataset, refining indicator weighting, and testing the tool’s applicability in a broader agricultural context. This enhances the robustness and guides stakeholders in sustainable agricultural development.

Home Office, Health Behavior and Workplace Health Promotion of Employees in the Telecommunications Sector during the Pandemic
Publication Name: International Journal of Environmental Research and Public Health
Publication Date: 2022-09-01
Volume: 19
Issue: 18
Page Range: Unknown
Description:
Our study aims to present the perception and experiences of employees at a large multinational telecommunications company in Hungary working in home offices, as well as their health behavior and the workplace health promotion during the SARS-CoV-2 COVID-19 outbreak. The sample consisted of the full sample of highly skilled employees at a large telecommunication multinational company (N = 46). Throughout the analysis, tests for homogeneity of variance were followed by a MANOVA test to compare the groups’ means by gender, age, and job classification. The results clearly show that in the short term, workers’ mental health did not deteriorate, they do not argue or fight more with their partners and are no more depressed or irritable than before. Workers are less likely to think of ways to be more effective at work than in a home office. Similarly, they do not think that employers have more expectations than before the pandemic. Our research shows the assumption about home workers being less efficient or less diligent in their daily work to be false. A supportive and flexible employer approach to health-conscious employees will be an essential aspect in the future.

Impact of heat and mass transfer in casson trihybrid nanofluid flow past an inclined cylinder, along with the effect of Soret and Dufour
Publication Name: Journal of Engineering Research Kuwait
Publication Date: 2026-06-01
Volume: 14
Issue: 2
Page Range: 2589-2602
Description:
The investigation of Casson trihybrid nanofluid flow and the heat and mass transfer properties on an inclined cylinder is related to the present study. Such an investigation encompasses the interaction among magnetohydrodynamics (MHD), porous-medium resistance, heat generation, thermal radiation, and cross-diffusion. The objective is to examine the body's parameters in relation to their influence on the transport process, and to compare water, hybrid nanofluid, and trihybrid nanofluid to establish the magnitude of improvement in thermal and mass transfer. Similarity transformations are then used to simplify the governing partial differential equations into a system of ordinary differential equations, and the results are obtained numerically using bvp4c, an inbuilt MATLAB solver. Previously published investigations and analyses support the model, and it is highly consistent with it. The results reveal that velocity decreases with the MHD Casson parameter, and the curvature parameter enhances the velocity distribution. Trihybrid nanofluids, blending multiple nanoparticles, deliver superior thermal conductivity and stronger convective heat transport than conventional formulations. Casson fluid behaviour and cylinder inclination together enhance mixed convection, while Soret and Dufour effects couple heat and mass transfer through cross-diffusion. From the comparative study of the base fluid, nanofluid, hybrid nanofluid, and trihybrid nanofluid, it can be concluded that the trihybrid nanofluid shows the most improvement in transport properties by yielding the highest skin-friction coefficient, Nusselt number, and Sherwood number. Thus, trihybrid nanofluids offer great potential for enhancing heat and mass transfer and can be used in more sophisticated thermal management systems and energy applications, including biomedical fluid transport.

Qualitative analysis of the sustainability of local attachment and identity based on in-depth interviews conducted in two scattered farmstead settlements
Publication Name: Discover Sustainability
Publication Date: 2025-12-01
Volume: 6
Issue: 1
Page Range: Unknown
Description:
Based on qualitative research, the paper focuses on the transformation of the traditional lifestyle of scattered farmsteads in recent decades, primarily driven by economic shifts and demographic changes. The challenging conditions of agriculture and farming, and the rise of alternative economic activities, such as tourism, recreation, and small-scale business, have reshaped these rural settlements, contributing to a different social landscape. Besides, another important trend is the influx of newcomers, including professionals, entrepreneurs, and pensioners, who adopt alternative, often non-agricultural lifestyles while maintaining a strong sense of place attachment and identity. In contrast, younger generations of native inhabitants tend to migrate elsewhere due to limited prospects, better education and job opportunities, leading to a generational shift in the population base. This study investigates two farmstead settlements exemplifying the tendencies, highlighting how sustainability is increasingly supported not by the continuation of traditional practices, but by the emergence of new lifestyle patterns such as agritourism and rural commuting. The process of change reflects a transition in the meaning and practice of rural living, where sustainability is redefined by changing forms of identity and attachment supporting the survival of farmsteads in a postmodern world.

Case Report: Transrectal ultrasound in adolescent Müllerian anomalies - bridging the gap between conflicting international guidance and real-world clinical pragmatism
Publication Name: Frontiers in Reproductive Health
Publication Date: 2026-01-01
Volume: 8
Issue: Unknown
Page Range: Unknown
Description:
An 18-year-old patient with an intact hymen presented with severe, cyclical dysmenorrhea, representing a common diagnostic challenge. Initial evaluation at an outside institution, including transabdominal ultrasound (TAUS) and magnetic resonance imaging (MRI), yielded an inaccurate initial radiological report, creating a diagnostic impasse. As transvaginal ultrasound (TVUS) is not feasible in this patient group, point-of-care transrectal ultrasound (TRUS) was performed, leveraging its superior near-field resolution, providing the definitive diagnosis of a non-communicating rudimentary uterine horn. The diagnosis established by TRUS was corroborated by intraoperative findings at laparoscopy. Surgical resection of the rudimentary horn resulted in complete and sustained symptom resolution, validating the clinical decision to pursue further investigation. This case, involving a routine application of a well-established technique, illustrates the diagnostic gap created by conflicting international guidance. This disconnect between recommendations and necessary clinical practice is particularly challenging in low-resource settings where advanced imaging is inaccessible. To address this uncertainty, we propose a pragmatic diagnostic algorithm positioning TRUS as a second-line, problem-solving modality. The pathway applies when initial non-invasive evaluation with TAUS and transperineal ultrasound (TPUS) is inconclusive due to limited fundal visualization. This highlights a key paradox: while guidance frameworks champion patient-centered principles, their rigid interpretation can create practical barriers in outlier cases. TRUS is then offered as a potential diagnostic step for consenting older adolescents when access to expert-interpreted MRI is either delayed or unavailable. This framework provides a clear pathway for formal studies to generate the evidence currently lacking in this specific population.

Lessons to be learned in adoption of autonomous equipment for field crops
Publication Name: Applied Economic Perspectives and Policy
Publication Date: 2022-06-01
Volume: 44
Issue: 2
Page Range: 848-864
Description:
Autonomous equipment for crop production is on the verge of technical and economic feasibility, but government regulation may slow its adoption. Key regulatory issues include requirements for on-site human supervision, liability for autonomous machine error, and intellectual property in robotic learning. As an example of the impact of regulation on the economic benefits of autonomous crop equipment, analysis from the United Kingdom suggests that requiring 100% on-site human supervision almost wipes out the economic benefits of autonomous crop equipment for small and medium farms and increases the economies-of-scale advantage of larger farms.

Dictionary-based assessment of European Sustainability Reporting Standard (ESRS) disclosure topics
Publication Name: Discover Sustainability
Publication Date: 2025-12-01
Volume: 6
Issue: 1
Page Range: Unknown
Description:
As the imperative for sustainable business practices and corporate responsibility has grown, the analysis and integration of Environmental, Social, and Governance (ESG) issues into corporate strategies has become a crucial aspect of business strategy. The paper assesses the ESG reporting preparedness of companies in the Central and Eastern European (CEE) region by analyzing their compliance with the European Sustainability Reporting Standards (ESRS). The study assesses the variability in disclosures across ESG pillars and examines their relationship with financial metrics using a test of independence and bootstrapped multiple regression. By employing an automated text analysis methodology on sustainability reports from top-performing companies, including Hungary, the Czech Republic, Poland, Austria, Slovenia, and Romania, the research identifies significant differences in reporting scores across various ESG disclosure topics. The results indicate that Climate Change (E1) scores are higher than those of other topics, suggesting an uneven emphasis on different aspects of sustainability. Furthermore, the analysis reveals that larger companies tend to achieve higher ESG scores, reflecting their greater resources for comprehensive and transparent reporting practices. The research contributes to the understanding of ESG reporting practices in the CEE region and highlights the importance of improvement in sustainability reporting to foster greater transparency and comparability. The findings suggest policy initiatives to encourage balanced reporting across all ESG topics and that companies, particularly smaller ones, could benefit from capacity-building efforts to enhance their reporting capabilities.

Determination of rail dilatation movements at tunnel gates for ballasted railway tracks in case of a greater change of temperature
Publication Name: Acta Technica Jaurinensis
Publication Date: 2026-05-27
Volume: 19
Issue: 2
Page Range: 137-154
Description:
The temperature change in continuously welded rail (CWR) tracks induces substantial internal stresses and shifts sleeper positions because the rails are longitudinally restrained from thermal expansion. This phenomenon is significantly intensified at tunnel portals, where a sharp contrast exists between the thermal boundary conditions of the open track and those of the sheltered tunnel environment. The current article investigates the dynamic interplay between rail dilatation and axial forces at these critical junctions by employing a finite-element (FE) model of the 54E1 rail track, calibrated using experimental measurements of track fastening parameters and ballast behavior. The research specifically examines the combined influence of temperature gradients between the tunnel and open environments, the bilinear longitudinal resistance of the ballast, and the mechanical braking loads exerted by passing trains. Through a series of parametric studies, the results demonstrate that simultaneous thermal and braking forces can trigger extreme rail displacements of up to 100 mm and axial forces of up to 1.4 MN. Notably, such high-stress states occur even when the ballast resistance is only 7 N/mm lower than the braking force. While increasing track fastening resistance helps equalize the impact of braking and thermal effects, it effectively reduces deflections to non-critical levels. The most severe stability risks are identified when the center of the braking zone aligns precisely with the portal. Ultimately, the study concludes that ballast resistance is the decisive factor in managing track integrity at tunnel entrances.
