Surface Brightness Gradients Produced by the Ring Waves of Star Formation [PDF]
, 1997 We compute surface brightness profiles of galactic disks for outwardly propagating waves of star formation with a view to investigate the stellar populations in ring galaxies. We consider two mechanisms which can create outwardly propagating star forming

Minimising efficiency roll-off in high-brightness perovskite light-emitting diodes
Nature Communications, 2018 Efficiency roll-off is a major issue for most types of light-emitting diodes (LEDs), and its origins remain controversial. Here we present investigations of the efficiency roll-off in perovskite LEDs based on two-dimensional layered perovskites.

Evidence for coloration plasticity in the yellow‐bellied toad, Bombina variegata
Ecology and Evolution, 2021 Phenotypic adaptation in terms of background color matching to the local habitat is an important mechanism for survival in prey species. Thus, intraspecific variation in cryptic coloration is expected among localities with dissimilar habitat features (e ...

A Comparison Between Alkali Peroxide and Activated Peroxide Processes in Bleaching Hardwoods Chemi-mechanical Pulp [PDF]
Iranian Journal of Wood and Paper Industries, 2013 Unbleached chemi-mechanical pulp of 85% pulp yield and produced from hornbeam, beech and populus woods respectively by 3:1:1 ratio, was used for peroxide bleaching. Two bleaching systems, alkali peroxide (conventional bleaching) and activated peroxide by
