The coloration of pigments obtained at different calcination temperatures was evaluated by the CIELAB
colorimetry or the [L.sup.*][a.sup.*][b.sup.*] colorimetric parameters.
Colorimetry. Figure 1 shows the yellowness index (YI) of UHMW-PE that was first irradiated with different doses and then thermally aged at 125[degrees]C.
Pesticide Malathion, tristimulus
colorimetry, psychometric attributes CIELAB space.
A Color analysis by tristimulus
colorimetry, in the inside the Annona Muricata with malathion at a concentration of 0.026 M, is developed in this work in order to identify variations between the variables in the CIELAB space, of Annona Muricata with Malathion in reference to base model of the fruit without contamination by pesticide.

colorimetry at 340 nm, based on the method of Marklund.
The N content was estimated by Kjeldahl method and the P and K content were determined by Mo-Sb
Colorimetry and Flame photometry method respectively [19].
Spot urine sample was collected on day 1 ([D.sub.1]), within 24 hours of entry into study protocol to measure UAE by immunoturbidimetry, and creatinine by
colorimetry using Benedict-Behre reaction.
The [P.sub.phy] content of the excreta was determined by
colorimetry according to Fruhbeck et al.

COLORIMETRY, 3RD ED.
Intended specifically for people who appreciate perfect hi-tech craftsmanship and state-of-the-art image quality, the Grand Cinema projectors rely on a combination of proprietary electronics, processing, and high-power lamps to deliver stunningly bright images (up to 10,000 ANSI lumens) without compromising
colorimetry or contrast ratio.
The last group was similar to the third group, with the difference that the second
colorimetry was done after 1 month.
