A Methodology for Continuous Monitoring of Rail Corrugation on Subway Lines Based on Axlebox Acceleration Measurements

Applied Sciences, 2023
Rail corrugation is a degradation phenomenon that manifests as a quasi-periodic irregularity on the running surface of the rail. It is a critical problem for urban railway lines because it induces ground-borne vibrations transmitted to the buildings near

DDT and Its Metabolites in Two Marine Dried Fish Species From Bangladesh: Residue Levels, Distribution Patterns, and Health Risk Assessment

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
A total of 96 dried fish samples of Harpadon nehereus and Trichiurus lepturus were analyzed by GC‐ECD to determine residues of 4,4′‐DDE, 4,4′‐DDD, and 4,4′‐DDT. The validated method showed satisfactory analytical sensitivity, with LODs of 0.30–0.39 μg/kg and LOQs of 0.92–1.18 μg/kg.

Increasing the Reuse Potential of High‐Strength Steels by Extending the Fatigue Life through Surface Treatments

steel research international, Volume 97, Issue 8, Page 4326-4336, August 2026.
Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse. To

Autofiction as relational mediation: A Ghost in the Throat and To Write as if Already Dead

Orbis Litterarum, Volume 81, Issue 4, Page 363-376, August 2026.
Abstract Because of its exploration of the self and the resemblance to online styles of publishing, autofiction has been accused by certain scholars of reflecting neoliberal tendencies. Hans Demeyer and Sven Vitse have developed a more nuanced view on the relation between autofiction and neoliberalism.
