TL;DR: In this article, the relative importance of individual aspects related to visual perception and attitudinal factors in public intention to oppose local wind turbines was investigated, i.e., the perceived unity of the environment, the personal attitude towards the effects of wind turbines on landscape aesthetics and recreation, and the general attitude towards wind power.

TL;DR: Individuals with high critical flicker fusion frequency (CFF) responded with a pronounced attenuation of EEG alpha waves, and an increase in speed and decrease in accuracy of performance when the light was powered by conventional and high-frequency ballasts.

TL;DR: Monitoring subjects' EEG while they were viewing fractals with different fractal dimensions shows that significant effects could be found in the EEG even by employing relatively simple silhouette images, pointing to a complicated interplay between different parts of the brain when experiencing this pattern.

TL;DR: It seems to be seasonal variation in the lighting conditions, both concerning intensities as well as regarding the pattern of the light exposure to which people living at high latitudes are exposed which may result in seasonal variations in the circadian profile of melatonin.
