Antimony glasses with large nonlinear refractive indices, small two-photon absorption coefficients and ultrafast response at telecom wavelengths
(2007-12-01)
Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, ...
A New Possibility for Fermentation Monitoring by Electrical Driven Sensing of Ultraviolet Light and Glucose
(2020-08-01)
Industrial fermentation generates products through microbial growth associated with the consumption of substrates. The efficiency of industrial production of high commercial value microbial products such as ethanol from ...
Functional diversity of phytochrome family in the control of light and gibberellin-mediated germination in Arabidopsis
(Wiley, 2014-03-12)
In several species, seed germination is regulated by light in a way that restricts seedling emergence to the environmental conditions that are likely to be favourable for the success of the new individual, and therefore, ...
Circadian and Sex Differences After Acute High-Altitude Exposure: Are Early Acclimation Responses Improved by Blue Light?
(Elsevier, 2015)
Objective.-The possible effects of blue light during acute hypoxia and the circadian rhythm on several physiological and cognitive parameters were studied.
Methods.-Fifty-seven volunteers were randomly assigned to 2 ...

The Influence of Light on Mood
(David Publishing Company, 2015-03)
Light is the most important environmental signal for the mammalian circadian system, and is detected exclusively by the eyes via specialized ganglion cell photoreceptors. Cycles of light and darkness relayed by the retina ...
Desenvolvimento de um controlador de luminosidade para LEDs de potência em corrente alternada
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrotécnica, 2013-04-11)
This paper aims to design and build a lighting controller (Dimmer) to power LEDs AC, aiming at a more affordable solution compared to the actual market. Was discussed the theories concerning the modeling of the device, ...
Let there be light: Regulation of gene expression in plants
(Landes Bioscience, 2014-10)
Gene expression regulation relies on a variety of molecular mechanisms affecting different steps of a messenger RNA (mRNA) life: transcription, processing, splicing, alternative splicing, transport, translation, storage ...
