The physiological cost of colour change: evidence, implications and mitigations [PDF]

open access: yes, 2022
Animals benefit from phenotypic plasticity in changing environments, but this can come at a cost. Colour change, used for camouflage, communication, thermoregulation and UV protection, represents one of the most common plastic traits in nature and is ...

Light fastness of printing inks: A review

open access: yesJournal of Graphic Engineering and Design, 2018
Light fastness, in its broadest sense, is the resistance of colours to fading under the influence of a light source. Light fastness is one of the most important physical, and therefore visual, properties sought in both pigments and in the inks ...

Experimental design of photo-Fenton process decolorization of Reactive Red 120 by using mathematical statistics models [PDF]

open access: yesJournal of Graphic Engineering and Design, 2018
A statistical design of experiments was used to evaluate the potential use of clay catalyst (CuOFeB) during photo-Fenton process in which the concentration of hydrogen peroxide (H2O2), catalyst loading and pH values were selected as effective ...

Animal vision and colour change for camouflage [PDF]

open access: yes, 2022
Camouflage is a well-studied form of antipredator defence. A key issue is how animals ensure camouflage effectiveness when the visual environments many camouflage strategies rely on vary.

Color change, phenotypic plasticity, and camouflage

open access: yesFrontiers in Ecology and Evolution, 2016
The ability to change appearance over a range of timescales is widespread in nature, existing in many invertebrate and vertebrate groups. This can include color change occurring in seconds, minutes, and hours, to longer term changes associated with ...

Synthesis and characterization of chromogenic fluoran compounds containing 4-ketoquinazolinone moieties [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
Chromogenic fluoran compounds containing 4-ketoquinazolinone were synthesized by reacting 2-(4-diethylamino-2-hydroxybenzoyl)benzoic acid with various substituted 4-ketoquinazolinones in the presence of sulfuric acid.

Colour change and kinetics of winter jujube slices during pulsed air-jet impingement drying

open access: yesCzech Journal of Food Sciences, 2018
The colour and the characteristics of colour change curves of winter jujube slices at different temperatures (55, 60, 65, 70, and 75°C) by the single factor experiment during pulsed air-jet impingement drying were stidied. The experimental data of colour

Effect of Artificial Ageing on Adhesive Bonds from Heat Treated Spruce

open access: yesDrvna Industrija, 2021
The influence of artificial ageing on bonded heat-treated spruce lamellas was investigated. Heat-treated spruce lamellas with different degrees of thermal modification were bonded with PVAc and MUF and then exposed to 500 artificial weathering cycles ...

Serological Benefit of SARS‐CoV‐2 Vaccination Relative to Infection in Children With Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.
