Color Dependence on Thickness in Topaz Crystal from Brazil
(HINDAWI PUBLISHING CORPORATIONNEW YORK, 2012)
It is well known that crystals of topaz from the Eastern Brazilian Pegmatite Province may turn blue by the irradiation with Co-60 gamma rays followed by heat treatment. Also, it is known that the sensation of color changes ...
Novel perceptually uniform chromatic space
(M I T Press, 2018-06)
Chromatically perceptive observers are endowed with a sense of similarity between colors. For example, two shades of green that are only slightly discriminable are perceived as similar, whereas other pairs of colors, for ...
Metodologia para cálculo da temperatura de cor e fluxo luminoso de um ou mais LEDs baseada apenas em dados do fabricante
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2020-08-24)
This work presents a methodology to estimate the correlated color temperature and the luminous flux of light sources composed of one or more white LEDs using only data from the manufacturer's specification sheet. The ...
Water content effect on the chromatic attributes of dehydrated strawberries during storage, as evaluated by image analysis
(Elsevier Science, 2013-07)
The changes of chromatic attributes due to different hydration degree, anthocyanins degradation and browning development were studied in dehydrated strawberries. Strawberry slices were freeze-dried, equilibrated at different ...

Influência do uso de líquidos modeladores na estabilidade cromática de resinas compostas
(Universidade Federal de Santa MariaBrasilOdontologiaUFSMPrograma de Pós-Graduação em Ciências OdontológicasCentro de Ciências da Saúde, 2021-04-15)
Modeling resins and dental adhesives are proposed as agents that facilitate the manipulation of composite resins. However, the possible effects on the chromatic stability of composite resins still represent a gap to be ...
Objective measurement of Akodon budini dorsal coloration: methodological concerns
(Academia Brasileira de Ciencias, 2016-03)
The role of color in taxonomic and systematic studies of several taxa is central. Color data are more valuable if they permit comparisons. We aimed to provide pelage objective color measurements of a series of Akodon budini ...
Sensing properties, energy transfer mechanism and tuneable particle size processing of luminescent two-dimensional rare earth coordination networks
(Royal Society of Chemistry, 2017-01)
A new isostructural family of layered coordination networks (CNs) based on rare earth elements and mixed ligands was hydrothermally synthesized and fully characterized. The set of compounds with the general formula ...
