Peculiarities of critical light opalescence in a spatially limited multicomponent system


Visions and voices of women and men with varying sexualities and identities shed critical light on a number of common theoretical assumptions about gender.


Critical light conditions for young Ecklonia cava and Eisenia bicyclis with reference to photosynthesis


This paper pursues this view and focuses on prosopagnosia both for the light that the theory can throw on the phenomenon, and for the critical light the phenomenon can throw on the theory.


At critical light intensities (0.5 to 0.1 μE m2 s1) only browncolored chlorobia were able to grow, though at low specific rates (0.002 days1 mg prot1).
