In these patients, a lower level of light is required to suppress melatonin secretion.
Switching on the new floodlighting, he claimed that it had a lower level of light pollution than the other cathedral's system.
This can be associated with the alteration in pigment composition of photosynthetic approach that possesses lower level of light harvesting chlorophyll proteins (LHCPS) (Loggini et al. [1999]; Gill et al. [2012]).
In one room on the lower level, dimly lit and quite cool, I inhaled and was suddenly seized by an attack of homesickness.
First, whereas there were significant differences in GSH levels between morphs of both sex in the booted eagle, the direction of the difference depended on sex in the Eleonora's falcon: melanic males had higher levels than light males, while melanic females had lower levels than light females.
The ordinance required the city to begin using energy-efficient bulbs, "cap" new lampposts to prevent light from flooding into the sky and maintain lower levels of light to prevent waste and glare, among other measures.
Keyes finds that working with lower levels of light, like candlelight, allows her to explore the uncharted elements of her visual lexicon.
However, this increases the optical path length and attenuates the total intensity causing lower levels of light to be collected which leads to higher system error.
This on-chip amplified Hamamatsu electron multiplier, back-thinned, Peltier-cooled CCD camera (EM-CCD C9100-12; 400–1,000 nm) provided up to 2,000× signal amplifier gain, thus allowing a lower level of excitation light to be used.
Surveys showed that after an initial adaptation period, office workers were generally satisfied with the lower level of ambient lighting.
