It is a commonly held belief that people feel better "when the sun is shining", however whilst acute exposure to sunlight and a pleasant temperature may anecdotally enhance mood, there appears to be an inconsistent relationship between seasonal variations and the prevalence of depression [ 131, 132].
LED technology has been incorporated into lighting regimes to modulate plant growth and development for decades as acute supplementation of sunlight (such as [ 11- 13]) or as the basis of plant growth in commercial chambers (as in [ 14]).
The assignment of candidate MAA biosynthetic genes and other relevant genes induced as an acute stress response to bright sunlight are listed in Table 1.
"The Gravity of Sunlight" is written with acute, sensuous detail, as if the events described had occurred not 30 years ago but just last week, just yesterday.
Increased amounts of soot in the atmosphere would block sunlight and cause an acute drop in global temperatures.
Following an acute oil spill, waves, wind and sunlight will cause weathering of the oil, altering the appearance and composition of the oil dramatically and dynamically [ 2].
Colour is the first visible pollution in water bodies which hampers its aesthetic nature, cuts-off sunlight penetration, disturbs photosynthesis and causes chronic and acute toxicity (Aksu et al. 2007; Gupta and Suhas 2009).
This shark has acute vision optimized for detecting the bioluminescence of its prey, as sunlight does not reach the depths at which it lives.
However, unlike our study, these studies only dealt with immediately acute effects and did not directly examine the effects of natural sunlight.
Yes, dark it is, with the very occasional "beam of sunlight falling slantways" from above, for the less-than-acute reader who might need to be reminded just how shadowy a tale he is about to enter.
Alternate potential contributory factors may be a direct impact of cold temperatures on blood pressure [ 26, 27], lower sunlight exposure and reduced vitamin D production in fall/winter [ 28], or acute illnesses such as influenza.
