Environmental light color affects the stress response of Nile tilapia
(2013-02-01)
We investigated the effects of environmental light colors (blue, yellow and white) on the stress responses (measured by changes in ventilatory frequency - VF) of Nile tilapia to confinement. After 7 days of light treatment, ...
Experimental Salmonella Gallinarum infection in light laying hen lines
(Sociedade Brasileira de Microbiologia, 2000-03-01)
Estudo anterior, realizado pelos mesmos autores com aves consideradas susceptíveis ao agente do tifo aviário, sugeriu que a relação entre a bactéria e a aves restringe-se ao período da enfermidade. Neste trabalho avaliou-se ...

Recent prospects on phosphor-converted LEDs for lighting, displays, phototherapy, and indoor farming
(2021-09-01)
Phosphor-converted white-light-emitting diodes (PC-WLEDs) are the main devices behind solid-state lighting (SSL) for both indoor and outdoor lighting, or backlight of liquid-crystal displays (LCD). Nonetheless, despite the ...
Application of low intensity light pulses to delay postharvest senescence of Ocimum basilicum leaves
(Elsevier Science, 2013-12)
Fresh basil (Ocimum basilicum L.) is a highly perishable leafy green vegetable with a storage life of 4–5 d at room temperature. Exposure of basil leaves to temperatures below 12 ◦C during storage results in chilling injury; ...
Human lice show photopositive behaviour to white light
(Pergamon-Elsevier Science Ltd, 2011-10)
We studied the behavioural response of body lice and head lice to white light. We also evaluated the influence of starvation and the presence of other individuals on this response. Experiments were performed in a rectangular ...
Red-green-blue upconversion emission and energy-transfer between Tm3+ and Er3+ ions in tellurite glasses excited at 1.064 mu m
(Elsevier B.V., 2003-02-15)
Red, green, and blue emission through frequency upconversion and energy-transfer processes in tellurite glasses doped with Tm3+ and Er3+ excited at 1.064 mum is investigated. The Tm3+/Er3+-codoped samples produced intense ...
