The Role of Cold Atmospheric Plasma in Surface Modification and Adhesion Behavior of Polypropylene/Flax Biocomposites

Polymer Composites, EarlyView.
Effects of plasma surface treatment on adhesive bonding of PP/flax biocomposites. ABSTRACT The emphasis on environmental sustainability has accelerated the adoption of biocomposites as alternatives to synthetic composites. However, their low surface energy may limit adhesion in bonding applications.

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

Wildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Occupational exposure to metal welding and cataract: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Background Metal welding generates ultraviolet radiation (UVR) of cataractogenic wavelengths, and UVR emitted during welding has been associated with cataract formation, but results from prior studies are conflicting. Methods We conducted a systematic review and meta‐analysis of epidemiological studies addressing associations between ...
