Behavior of broilers reared under monochromatic and fluorescent light sources
(2016-01-01)
The study aimed to evaluate the behavior of broiler chickens reared in the blue and red light emitting diode (LED), using a fluorescent light as a control. The bird behaviors were recorded at 28, 35 and 42 d of grow-out ...
Photodynamic antimicrobial chemotherapy on streptococcus mutans using curcumin and toluidine blue activated by a novel LED device
(2015)
Photodynamic antimicrobial chemotherapy (PACT) is an antimicrobial approach that uses photosensitizers (PS) in combination with light sources at specific wavelengths aiming the production of reactive oxygen species. The ...
Image analysis for studying the behaviour of broilers exposed to artificial LED lighting
(2015-01-01)
The photoperiod length and the type of light may influence both growth and behaviour of reared birds. The aim of this study was to evaluate broilers' behaviour when exposed to different LED colours. The study was carried ...
TiO2 and N-TiO2-photocatalytic degradation of salicylic acid in water: characterization of transformation products by mass spectrometry
(Springer Heidelberg, 2020-08)
The aim of this work is to study the byproducts formed as a result of the photocatalytic process under different conditions of light wavelength and photocatalyst doping, rendering valuable information about the fate of ...

Modeling of the influence of light quality on the growth of microalgae in a laboratory scale photo-bio-reactor irradiated by arrangements of blue and red LEDs
(Elsevier, 2014-05)
Research on microalgae has grown significantly over the past few decades, due to their multiple uses and applications. The distribution of the density of radiant energy within the photo-bio-reactor and its impact on the ...
Eu(II)-Activated Silicates for UV Light-Emitting Diodes Tuning into Warm White Light
(2020-08-01)
White-light-emitting diodes (WLEDs) are the main white light source for general lighting due to high-luminous efficacy (>150 lm W−1), long lifespan (5 × 104 h), and environmentally friendly properties. Despite the current ...
