Per‐ and Polyfluoroalkyl Substances (PFAS) Exposure Profiles and Their Predictors in a Study of US Volunteer Firefighters

American Journal of Industrial Medicine, Volume 69, Issue 9, Page 745-764, September 2026.
ABSTRACT Introduction Firefighters may experience occupational exposure to per‐ and polyfluoroalkyl substances (PFAS). Volunteer firefighters make up 65% of the US fire service, but their serum PFAS profiles have not been well characterized. This study aims to (1) describe PFAS serum profiles among US volunteer firefighters from 9 states enrolled in ...

Inter‐Set Blood‐Flow Restriction Increases Peripheral Physiological Stress While Preserving Repeated‐Sprint Mechanical Output in Trained Athletes

European Journal of Sport Science, Volume 26, Issue 9, September 2026.
ABSTRACT Inter‐set blood‐flow restriction (BFR) may increase the physiological stimulus of repeated‐sprint exercise without compromising mechanical output, but evidence in trained athletes is limited. In a randomized crossover design, 26 national‐level male badminton players completed three 5 × 5‐s cycling sprints (25‐s intra‐set rest, 3.5‐min inter ...

Dynamic Characteristics Analysis of a Large Wind Turbine Gearbox Supported by Journal Bearings Under Different Lubrication States

Wind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT Due to their superior load density, planetary gear journal bearings (PGJB) are progressively replacing rolling element bearings in wind turbine gearboxes; therefore, accurately revealing the dynamic characteristics of drivetrains supported by these bearings under variable operating conditions is crucial for ensuring operational reliability ...
