Cognitive Performance in Young Adults During Three Consecutive Days of Simulated Occupational Heat Stress: An Exploratory Study

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Global increases in occupational heat exposure are raising concerns about worker safety and cognitive performance during prolonged and repeated shifts. At present, the cumulative effects of repeated heat exposure on cognitive performance remain unclear.

Seismic Performance and Vibration‐Based Damage Identification of Two‐Storey Balloon‐Framed CLT Shear Walls

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT While cross‐laminated timber (CLT) is increasingly utilized in lateral force‐resisting systems in mass timber construction, research has predominantly focused on platform‐type construction. Balloon‐type CLT shear wall systems offer distinct structural advantages, notably the elimination of cumulative perpendicular‐to‐grain compression and a ...

Review of articular cartilage repair techniques and their application in the horse

Equine Veterinary Journal, EarlyView.
Abstract Articular cartilage lesions represent a significant career‐limiting problem in athletic horses. A healthy articular cartilage surface is vital for optimal joint function, and defects can result in irreversible degenerative changes. Successful treatment of cartilage lesions remains a long‐standing challenge for orthopaedic surgeons, prompting ...

Direct Measurement of Explosive Impulse From Contact to the Ultra‐Near Field

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measurement of impulse from explosive charges in contact and ultra‐near‐field regimes remains poorly characterised due to the short duration of loading, high strain rates, and the difficulty of obtaining direct momentum‐based measurements.
