[F.sub.0]: minimal fluorescence in dark-adapted
state; Fm: maximum fluorescence in dark-adapted
state; (F'm-F')/F'm: PSII operating efficiency; Fv/Fm: maximum quantum yield; [R.sub.fd]: fluorescence decline ratio in steady-state; NPQ: non-photochemical quenching during light adaptation.
The ERG b-wave amplitudes was recorded under dark-adapted
control (n = 6) and NiONP treatment conditions and compared.
NPQ as a non-photochemical- quenching parameter relating to the dark-adapted
state, whatever, is associated with a change in the efficiency of heat dissipation (Li and Ong, 1997).
E curve (dimensionless) [F.sub.o], [F.sub.m] Minimum and maximum fluorescence emitted by a dark-adapted
sample (arbitrary units) [F.sub.s], [F'.sub.m] Steady-state and maximum fluorescence emitted by a light-adapted sample (arbitrary units) [F.sub.v]/[F.sub.m] Maximum quantum yield of PSII of a dark-adapted
sample (dimensionless) LC Light curves: steady-state rETR vs.
Over a 14-hour span on September 23, centred on 11:50UT, Uranus draws to within one arcminute of 44 Piscium--an angular separation less than the dark-adapted
eye's resolution limit.
The experiments were conducted on a dark-adapted
partial preparation that included the eye ball, optical nerve, and cerebral ganglion.
Then, to our dark-adapted
eyes, we would see them glow in a variety of colors.
Let us first discuss what happens when one illuminates a dark-adapted
leaf, i.e., a leaf that has been in the dark for a period of time long enough so that all the components of the photosynthetic electron transport chain are in the oxidized state (2).
In particular, their practical utility is illustrated by analysis of gold particles labelling the phosphoprotein, phosducin, in subcellular domains of rod photoreceptors in the retinas of light- and dark-adapted
groups of rats (Chen et al., 2005).
Following L&Z supplementation, a significant MPOD increase was accompanied by improved pattern electroretiongram amplitude and increased dark-adapted
For this reason it may be a good idea to keep one eye closed while you turn on the light and have it remain dark-adapted
Thus it is that a romantic, page-turning supernatural/psychological mystery like Sarah Waters' Affinity gets pride of place in "Literature," while brilliant fictions like A Dark-Adapted
Eye by Barbara Vine (a pseudonym of Ruth Rendell) have to slug it out next to genre retreads in the "Mystery/Thriller" section.
