Limited Agreement Between Perceptual and Physiological Heat Strain at Initial Stay Times for Continuous Work in the Heat Before Heat Alleviation Controls

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Accurate assessment of heat strain at initial stay time (IST; core temperature 38.0°C or Δ1.0°C above resting), when heat mitigation decisions are required, is critical for managing occupational heat exposure. We evaluated the relationship and agreement between physiological (Physiological Strain Index [PSI] and adaptive PSI [aPSI]

Timing of Work‐Rest Implementation Influences Worker Productivity Under Heat Stress: Evidence for Initial Stay Time‐Based Scheduling

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Work‐rest allocations recommended by the American Conference of Governmental Industrial Hygienists (ACGIH) limit heat strain and are typically implemented from the onset of work. Whether delaying implementation until after the initial stay time (IST; the duration of continuous work before core temperature reaches 38.0°C) improves ...

Methacrylated Gelatin and Graphene Oxide Hybrid Hydrogels Composed‐Bioinks for 3D Tissue Engineering

Advanced NanoBiomed Research, EarlyView.
Bioinks made from hydrogels, such as methacrylated gelatin (GelMA), serve as the base material for bioprinted tissues, offering versatility and biocompatibility for a range of applications. Additional components however are still needed to improve functionality and mechanical stability of hydrogels. One of these components is graphene oxide (GO), added
