Optimization of a Green Dyeing Process Using Natural Dyes Extracted from Corchorus Olitorius Leaves
Journal of Natural Fibers, 2023 The main purpose of this study is to develop a green dyeing process using Corchorus olitorius dye extract. Corchorus olitorius leaves were used as a new dyestuff source that has never been used for cotton fabric dyeing. Dye extraction was performed using

Minimal coloring and strength of graphs
Discrete Mathematics, 2000 A proper vertex coloring \(c\) of a graph \(G\) using colors \(1,2,\dots\) is said to be minimal if \(\sum_{v\in V(G)} c(v)\) is minimum among all vertex colorings of \(G\). The vertex strength of \(G\), denoted by \(s(G)\), is the smallest number of colors needed to obtain a minimal coloring of \(G\). (The edge strength of \(G\), denoted by \(s'(G)\),

Contrast Affects the Strength of Synesthetic Colors
Cortex, 2006 Grapheme-color synesthesia is an automatic, involuntary experience of seeing colors when viewing numbers, letters or words on a printed page. Previous research has demonstrated that synesthesia is a genuine perceptual phenomenon, but crucially, all of these experiments have used high-contrast letters and numbers.

THE STRENGTH OF RAMSEY’S THEOREM FOR PAIRS AND ARBITRARILY MANY COLORS [PDF]
The Journal of Symbolic Logic, 2018 AbstractIn this article, we will show that ${\rm{R}}{{\rm{T}}^2} + WK{L_0}$ is a ${\rm{\Pi }}_1^1$-conservative extension of ${\rm{B\Sigma }}_3^0$.

Knowing color terms enhances recognition: Further evidence from English and Himba [PDF]
, 2009 Two experiments attempted to reconcile discrepant recent findings relating to children’s color naming and categorization. In a replication of Franklin and colleagues (Journal of Experimental Child Psychology, 90 (2005) 114–141), Experiment 1 tested ...
