Effect of high energy radiation on technical polymers [PDF]

open access: yes, 2023
Fiber reinforced polymers (FRP) offer excellent fatigue resistance in combination with low specific weight. However, in contrast to metals, microscopic damage is usually present right from the beginning of cyclic loading and calls for insights on ...

Exploring trends in admissions and treatment for ankle fractures: a longitudinal cohort study of routinely collected hospital data in England

open access: yesBMC Health Services Research, 2020
Background Evidence on the most effective and cost-effective management of ankle fractures is sparse but evolving. A recent large RCT in older patients with unstable fractures found that management with close-contact-casting was functionally equivalent ...
