Valorization of Garcinia humilis Residues in Active Collagen/Starch Films for Biodegradable Packaging Applications

Packaging Technology and Science, EarlyView.
Residues from Garcinia humilis were used to obtain a phenolic‐rich extract (GHRE) and incorporated into collagen–starch films. The addition of GHRE improved antioxidant activity, thermal stability and elasticity, while reducing water vapour permeability.

Scaling of large chromatic differences

Vision Research, 1974
Abstract Minimally-distinct borders between juxtaposed heterochromatic fields arc evaluated by equivalent achromatic contrasts or by subjective ratings and are in each case subjected to the Shepard Kruskal multidimensional scaling analysis. The results of the analysis show that the original stimuli can be orderly arrayed in a two-dimensional space on

The Chromatic Scale: Second Octave

2023
Abstract With just a couple of changes to the chromatic scale introduced in Chapter 20, a second octave can be added to the chromatic scale, introduced here in Chapter 21.

Rectangular Uniform-Chromaticity-Scale Coordinates

Journal of the Optical Society of America, 1939
The advantages and limitations of the I.C.I. coordinate system and the trilinear coordinate system yielding uniform chromaticity scales as proposed by Judd are compared. The advantages for engineering applications of a system combining rectangular coordinates with the uniform chromaticity scale (U.C.S.) are pointed out. The U.C.S.

Uniform Chromaticity Scales — New Experimental Data

Journal of the Society of Dyers and Colourists, 1982
Sets of coloured paint and textile samples have been prepared, each set consisting of pairs of samples giving small chromaticity differences with a good coverage of the possible directions. For most sets the lightness differences were negligible, but for a few sets extra samples showing significant lightness differences were included.

(θ, δ) uniform-scale chromaticity diagram

Computer Physics Communications, 1992
The non-uniformity of scale in the usual chromaticity diagrams is a very old problem in colour measurements. This program computes the transformation from the CIE 1931 (x, y) chromaticity diagram to the recent uniform scale (θ, δ) diagram and vice-versa. Moreover the program evaluates the most important colorimetric quantities for a comparison with the

Equal Beating Chromatic Scale

The Journal of the Acoustical Society of America, 1957
An unequal temperament is described in which the fifths and fourths of the tuning chain have the same beat rate. No Wolf intervals are produced and all intervals can be described by ratios of integers. The equal heating chromatic scale is an excellent approximation to equal temperament; moreover it may well represent a closer approximation to Bach's ...

The Fry Uniform Chromaticity Scale Diagram

Topical Meeting on Color Appearance, 1987
In 1945 I1 formulated a theory of the retinal mechanisms for generating signals in the optic nerve fibers that would provide a basis for my modulation theory of color vision. In the process I developed a uniform chromaticity scale diagram.

Color differences scaled by chromatic modulation sensitivity functions

Vision Research, 1978
Abstract Chromatically-modulated spatial stimuli were produced by superimposing two equally bright sine-wave gratings 180° out of phase on a uniform background field. Each of the gratings was illuminated with a different monochromatic light, and the background field contained an equal-brightness mixture of the same two lights as in the gratings.
