In Vitro Study of the influence of the pigments of three colored gels over the light distribution of visible light by digital images
(Spie - Int Soc Optical Engineering, 2009-01-01)
Nowadays the real contribution of light on the acceleration of the chemical reaction for the dental bleaching is under incredulity, mostly because the real mechanisms of its contribution still are obscure. Objectives: ...
Artificial Lighting as a Vector Attractant and Cause of Disease Diffusion
(US DEPT HEALTH HUMAN SCIENCES PUBLIC HEALTH SCIENCE, 2010)
BACKGROUND: Traditionally, epidemiologists have considered electrification to be a positive factor. In fact, electrification and plumbing are typical initiatives that represent the integration of an isolated population ...
Carotenoid biosynthesis and plastid development in plants: the role of light
(MDPI, 2021)
Light is an important cue that stimulates both plastid development and biosynthesis of carotenoids in plants. During photomorphogenesis or de-etiolation, photoreceptors are activated and molecular factors for carotenoid ...
