Degradation of acrylic water base color from synthetic wastewater by the Fenton process was performed. Experiments were conducted on the sample containing 100 and 400 mg/l of Acrylic water base color. The study was performed for searching optimum values of FeSO4 and H2O2 concentration, pH and temperature. The H2O2 requirement seems to be re...

PURPOSE This study aimed to quantify the shift of colorimetric values in the Ishihara pseudoisochromatic test with aging of the plates. METHODS Three sets of Ishihara pseudoisochromatic plates with different published dates (printed in 1971, 1983 and 2001) were tested. Positions matching 32 dots with 13 colors were chosen from each set and the colorimetric values with the CIELAB and HSB/HLS c...

This reserch proposes a method to provide an appropriate illuminance and color temperature in an office lighting environment for individual workers. For the control algorithm, based on the optimization method called Simulated Annealing (SA), a method including a neighborhood design mechanism for the design variables instead of a temperature parameter was used. In addition, for changes in the lu...

Studies show that Oryza sativa L. contains a structure named β-glucan with anti cancer properties. In the present study, a tissue culture for rice was carried out and β-glucan content was measured under various sugar and vitamin levels in basic MS medium. Seeds of Hashemi cultivar were cultured on MS medium. Two plant hormones, namely, 2,4-D (0, 1, 1.5, 2 and 3 mg/l) and kinetin (0,0.5, 1, and ...

In this study, the Fenton process was used to investigate the color removal efficiency of Acid Red 52 and Basic Red 18 dye solutions by direct chemical oxidation. Color and chemical oxygen demand (COD) was successfully removed more than 99% and up to 92% respectively. This article would provide an easy assessment of the viability of using Fenton reagent in acidic conditions, so it is a prom...

The International Color Consortium (ICC) has developed and refined a comprehensive and rigorous system for managing color. The CIE technical committee 8-01 has proposed a color appearance model for imaging applications. This paper describes issues that have to be considered when the CIECAM02 color appearance model is used within the framework of the ICC color management system. They concern dec...

Synesthesia is a perceptual phenomenon in which stimuli can trigger experiences in non-stimulated sensory dimensions. The literature has focused on forms of synesthesia in which stimuli (e.g. music, touch or numbers) trigger experiences of color. Generally missing, however, is the observation that synesthetic colors are often accompanied by the experience of other surface properties such as tex...

Effects of the dark-cutting condition were examined on commercially slaughtered beef carcass sides that were classified into groups exhibiting 1/3, 1/2, and full degrees of the dark-cutting (DEGDC) condition, as evaluated by a USDA-Agricultural Marketing Service grader (n = 20 per group). Twenty-nine muscles of each carcass side were evaluated to determine the ultimate pH and color (L*, a*, and...

It is essential to understand the consumption pattern of food and how it changes over time to formulate sound economic policies as well as marketing and pricing strategies. In this study, we estimate the Quadratic Almost Ideal Demand System with six rounds of the Family Income Expenditure Survey exploiting the conditional linearity of the demand system. We find that the Filipino diet has become...
