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 ...
Análise luminotécnica do sistema de iluminação de uma indústria metalúrgica
(Universidade Tecnológica Federal do ParanáMedianeiraBrasilTecnologia em Manutenção IndustrialUTFPR, 2014-01-12)
Artificial lighting developed to simulate natural lighting and has been enhanced to used environments and forms different. The regulatory standards was important enactment lighting for workers´ healthy conditions. This ...

Acute Effects of Light on Alternative Splicing in Light-Grown Plants
(Wiley Blackwell Publishing, Inc, 2015-12)
Light modulates plant growth and development to a great extent by regulating gene expression programs. Here, we evaluated the effect of light on alternative splicing (AS) in light-grown Arabidopsis thaliana plants using ...
Surveillance on the light-front gauge-fixing Lagrangians
(2004-08-20)
In this work we propose two Lagrange multipliers with distinct coefficients for the light-front gauge that leads to the complete (non-reduced) propagator. This is accomplished via (n · A)2 + (∂ · A) 2 terms in the Lagrangian ...

STUDY OF AGITATION, COLOR AND STRESS LIGHT VARIABLES ON Spirulina platensis CULTURE IN A VERTICAL STIRRED REACTOR IN STANDARD MEDIUM
(Univ Autonoma Metropolitana-iztapalapa, 2020-01-01)
Spirulina platensis is a helical-shaped photosynthetic cyanobacterium. Its cultivation depends on light intensity, nutrients, pH, cell density, temperature, among others. Microalgae are capable of growing in open and closed ...
