To monitor response of herb layer species to canopy openings, we created three single-tree (33-36 m 2) and three multitree (51-151 m 2) gaps in a northern hardwoods stand. Percent cover of herbs and ...

The single-layer masks reduced spreading droplets from speaking, but the double-layer face covering was better at preventing the spread of droplets from coughing and sneezing, the authors stated.

When heat is used as a stimulus for the self-healing process, the display cover layer may include transparent conductors that form a heating layer in the display cover layer.

Crucially, the cover would allow light through, either by using extremely thin layers of the externally-covering material, or by including perforations.
