Color terms and color concepts [PDF]

open access: yesJournal of Experimental Child Psychology, 2006
In their lead articles, both Kowalski and Zimiles (2006) and O'Hanlon and Roberson (2006) declare a general relation between color term knowledge and the ability to conceptually represent color. Kowalski and Zimiles, in particular, argue for a priority for the conceptual representation in color term acquisition.

Exploring the Chemical Complexity and Toxicological Behaviour of Semi‐permanent Make‐Up Pigments: A Systematic Review

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.

Decolorization of Palm Oil Mill Effluent by Klebsiella Pneumonia ABZ11: Remediation Efficacy and Statistical Optimization of Treatment Conditions

open access: yesFrontiers in Microbiology, 2020
Colorants contained in palm oil mill effluent (POME) are recalcitrant and carcinogenic in nature. The commonly applied ponding treatment methods have been reported inefficient for remediating the concentration of the colorants before discharge.

IR ion spectroscopy in a combined approach with MS/MS and IM-MS to discriminate epimeric anthocyanin glycosides (cyanidin 3-O-glucoside and -galactoside) [PDF]

open access: yes, 2019
Anthocyanins are widespread in plants and flowers, being responsible for their different colouring. Two representative members of this family have been selected, cyanidin 3-O-β-glucopyranoside and 3-O-β-galactopyranoside, and probed by mass spectrometry ...

Color Geometry – Or Color Grammar? [PDF]

open access: yes, 2019
This article discusses some difficulties of the theory of color propounded by Meinong in his Re-marks on the Color Solid and the Mixture Law of 1903. First, I argue that Meinong’s geometrical approach faces at least three sets of difficulties related to the following assumptions: colors pos-sess a “nature” that can be grasped through intuition; they ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

A novel use of purple tulip petal anthocyanins in pH‐sensitive polyvinyl alcohol films for the real‐time monitoring of shrimp freshness

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Shrimp is among the most perishable seafood commodities, and its freshness is still largely assessed through time‐consuming laboratory methods. pH‐responsive colorimetric films have received growing attention as they allow visual, real‐time quality monitoring without specialized equipment.
