A qualitative exploration of narratives among problematic exercise experiences

Álvaro Sicilia Manuel Alcaraz-Ibáñez Mark D. Griffiths Attila Szabo

Publication Name: Journal of Behavioral Addictions

Publication Date: 2026-03-01

Volume: 15

Issue: 1

Page Range: 497-508

Description:

Background and Aims: Exercise is recognized as essential for health, but exercise addiction remains a lesser-known phenomenon. Unlike substance addictions, excessive exercise is often celebrated, making it difficult to distinguish between dedication and compulsion. To understand what exercisers perceive as problematic within their exercise context, a qualitative study was conducted investigating personal experiences.MethodsThrough a reflexive thematic analysis, the present study analyzed 153 narratives from individuals who experienced physical, psychological, or emotional problems due to exercise.ResultsFour main themes emerged: (i) The social pressure of a performativity-oriented culture; (ii) Everything seemed to be going well until the injuries appeared; (iii) Time is money: Interpersonal conflicts; and (iv) It is my responsibility: Intrapersonal conflict. The results suggest that a culture of performance provides an interpretive framework that shapes and sustains problematic exercise experiences. Participants internalized performative values, leading to strict demands and fear of failure, resulting in severe injuries in over 70% of cases. In participants' narratives, the forced interruption of activity was associated with the reported emergence of withdrawal symptoms, with health and morality discourses providing the framework for rationalizing their excessive dedication.ConclusionsThese findings suggest that problematic exercise is not an individual issue, but an expression of a broader culture prioritizing performance. These results underscore the importance of shifting toward biopsychosocial interventions that foster identity flexibility and prioritize holistic well-being and enjoyment over performance metrics.

Prudent use of antibiotics in pig farming: National and international practices and regulatory framework

László Búza Szabó István László Gombos Veronika Gombosné Szűr László Varga

Publication Name: Magyar Allatorvosok Lapja

Publication Date: 2026-01-01

Volume: 148

Issue: 2

Page Range: 103-120

Description:

Antimicrobial agents, and especially antibiotics, have played a crucial role in combating infectious diseases for decades. As antimicrobial resistance (AMR) becomes more widespread, treatment efficacy decreases, leading to therapeutic failures and significant economic consequences. Global efforts to address AMR are increasingly guided by the “One Health” approach, which emphasizes coordinated strategies spanning human, animal, plant, and environmental health. AMR is now one of the most pressing global health challenges, affecting humans, animals, crops, and ecosystems alike. Among its many contributing factors, the inappropriate use of antimicrobials is particularly critical. To better understand the factors influencing AMR and to implement and assess strategies for reducing antimicrobial use (AMU), accurate and detailed data on actual usage and indications are essential. Systematic data collection allows stakeholders to evaluate their current antibiotic practices and identify areas needing intervention. In EU member states with established traditions of AMU analysis, centralized databases facilitate benchmarking across sectors and countries; however, reporting and analyzing AMU data remains a significant challenge for both EU and national administrations. At the societal level, growing consumer concern demands that veterinarians and livestock keepers gain a deeper understanding of the root causes of disease and production losses. This knowledge supports informed decision-making aimed at improving overall herd health, ensuring economic viability, promoting responsible AMU, and reducing environmental impact. Experience in Hungary and abroad shows that achieving optimal AMU in large-scale livestock farming requires a shift in mindset. This literature review aims to provide a comprehensive overview of the global, European and Hungarian challenges in the fight against antibiotic resistance. It also presents current data collection and monitoring systems, along with the core principles and strategies of responsible AMU.

Effects of Location and Height of Vortex Generators on Aerodynamic Performance of NACA 4412 Airfoil

I. Lakatos Dénes Ágoston Solnay József Molnár

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2025-01-01

Volume: 53

Issue: 3

Page Range: 267-276

Description:

This study focuses on the aerodynamic effect of vortex generators (VGs) placed on the wing surface, with a focus on the height and chordwise position of the VGs. NACA 4412 airfoil was used for the investigation, which is a frequently used and well-researched airfoil in the aerospace industry, with a chord length (c) of 200 mm. Six different configurations have been analyzed with Computational Fluid Dynamics (CFD), with three chordwise positions (x) and two trailing edge heights (h). The results showed that VGs placed furthest from the leading edge (x/c = 20%) were able to increase lift and reduce drag to the greatest extent. In terms of height, the shorter (h/c = 0.5%) VGs produced the most lift. These results provide valuable insights as to how vortex generator design can be optimized for aerodynamic performance across various operating conditions.

On the Applicability of Fuzzy Lines in Circular Hough Transform in Lesion Segmentation on Liver CT Images

Melinda Kovacs Szilvia Nagy

Publication Name: Studies in Computational Intelligence

Publication Date: 2023-01-01

Volume: 1040

Issue: Unknown

Page Range: 45-54

Description:

Most of the lesions that grow in the liver and need to be found on a CT take are roundish, though especially in the case of malignant lesions the irregularity of the shape is also rather common. Classical Hough transform, however, which is one of the most used methods for finding circles, usually fails to find the contours of these objects, because of the larger or smaller irregularity of the shapes. Introducing a fuzzification in the edge filtered version of the image, which is usually the basis of a Hough transform, makes the Hough transform more flexible for using in liver CT image analysis.

Unveiling the significance of rhizosphere: Implications for plant growth, stress response, and sustainable agriculture

Zoltán Molnár Tibor Janda Wogene Kabato

Publication Name: Plant Physiology and Biochemistry

Publication Date: 2024-01-01

Volume: 206

Issue: Unknown

Page Range: Unknown

Description:

In the rhizosphere, the activities within all processes and functions are primarily influenced by plant roots, microorganisms present in the rhizosphere, and the interactions between roots and microorganisms. The rhizosphere, a dynamic zone surrounding the roots, provides an ideal environment for a diverse microbial community, which significantly shapes plant growth and development. Microbial activity in the rhizosphere can promote plant growth by increasing nutrient availability, influencing plant hormonal signaling, and repelling or outcompeting pathogenic microbial strains. Understanding the associations between plant roots and soil microorganisms has the potential to revolutionize crop yields, improve productivity, minimize reliance on chemical fertilizers, and promote sustainable plant growth technologies. The rhizosphere microbiome could play a vital role in the next green revolution and contribute to sustainable and eco-friendly agriculture. However, there are still knowledge gaps concerning plant root-environment interactions, particularly regarding roots and microorganisms. Advances in metabolomics have helped to understand the chemical communication between plants and soil biota, yet challenges persist. This article provides an overview of the latest advancements in comprehending the communication and interplay between plant roots and microbes, which have been shown to impact crucial factors such as plant growth, gene expression, nutrient absorption, pest and disease resistance, and the alleviation of abiotic stress. By improving these aspects, sustainable agriculture practices can be implemented to increase the overall productivity of plant ecosystems.

Adaptive differential evolution approaches in real-time optimization of co-generation systems for enhanced energy minimization

Sharifah Rafidah Wan Alwi Fakhrony Sholahudin Rohman Dinie Muhammad Ashraf Azmi Hong An Er Siti Nor Azreen Ahmad Termizi

Publication Name: Thermal Science and Engineering Progress

Publication Date: 2026-03-01

Volume: 71

Issue: Unknown

Page Range: Unknown

Description:

This paper examines Real Time Optimization (RTO) for an industrial cogeneration plant featuring a tightly coupled multi boiler turbine network, in which fluctuating steam and power demands and fuel price volatility necessitate continual economic re optimization while preserving closed loop stability. Three evolutionary optimizers are Differential Evolution (DE), Hybrid Differential Evolution (HDE), and Adaptive Differential Evolution (ADE) deployed as the supervisory RTO layer above the regulatory controllers, with Model Predictive Control (MPC) regulating boiler pressure (Control Variable 1, CV1) and drum level CV2 and PI or PI loops regulating turbine power. A deterministic, repeatable stress test is introduced through sequential step changes in high pressure steam demand, medium pressure steam demand, power demand, and natural gas price, enabling systematic evaluation of transient adaptability and robustness. Over five boilers and the turbine network, multi run mean and deviation results show that ADE delivers the most consistent overall behavior, yielding smoother operating trajectories, improved tracking, and lower energy usage. Specifically, the total integrated energy consumption is approximately 895 MWh with ADE, compared to 926 MWh with DE and 1259 MWh with HDE, equivalent to reductions of about 3 percent versus DE and 29 percent versus HDE. Control performance improves in parallel the mean boiler pressure (Integral Square Error) ISE CV1 drops by roughly 68 percent relative to DE and 71 percent relative to HDE, while turbine regulation shows substantial enhancement with turbine ISE reduced by about 98 percent compared with DE. Overall, the results demonstrate that adaptive evolutionary optimization strengthens coordination between the RTO and control layers, providing a robust and energy efficient strategy for real time cogeneration operation under dynamic demand and price disturbances.
