Sign Up to like & getrecommendations! Published in 2020 at "Journal of Applied Phycology"
DOI: 10.1007/s10811-020-02310-1
Abstract: A numerical study of the motion of algal cells in a representative thin-layer-cascade (TLC) photobioreactor is presented. The goal is to determine the time scale associated with the light/dark (L/D) cycle seen by the cells… read more here.

DOI: 10.1016/j.brainres.2017.08.002
Abstract: Cannabinergic receptor 1 (CB1r) is highly expressed in almost the entire brain; hence, its activation affects diverse functions, including cognitive processes such as learning and memory. On the other hand, it has been demonstrated that… read more here.

DOI: 10.1016/j.cub.2016.12.041
Abstract: Reduced exposure to daytime sunlight and increased exposure to electrical lighting at night leads to late circadian and sleep timing [1-3]. We have previously shown that exposure to a natural summer 14 hr 40 min:9 hr 20 min light-dark… read more here.

DOI: 10.1080/07420528.2021.1998103
Abstract: Puberty onset is tightly regulated by a broad spectrum of neuroendocrine signals and peripheral stimuli which coordinate the hypothalamic-pituitary-gonadal (HPG) axis activation. Numerous studies suggest that light stimulation influences HPG axis function; however, the effect… read more here.
