In this paper the effect of whiteness attribute of white substrates on blackness property of black coated fabrics is investigated. To this aim, four cotton fabrics with different whiteness and tint attributes are used as white substrates. To prepare a set of black samples, various concentrations of four color pigments, i.e., red, green, blue and yellow, were mixed with the black one and applied...

While black is one of the most prevalent industrial colors in the world, the colorimetric attributes of what is considered black vary significantly and the range of subtle hue undertones can be numerous. However, no systematic study can be found in the literature pertaining to the potential role of colorimetric attributes in the perceptual assessment of blackness. We have experimentally determi...

In this paper, a comparative study on the effect of different heat treatment temperatures, i.e., 400, 500, 600 and 700 oC on colorimetric properties of CoFe2O4 nanoparticles has been done for the first time. Then, the mentioned Co-Fe mixed oxide pigments are dispersed in an amorphous silicon oxide matrix to form CoFe2O4/SiO2 nanocomposites. In the next step, the optical properties of nanocompos...

background; dithiocarbamates, the main group of fungicides, are used to control about 400 pathogens in more than 70 crops. these pesticides are widely applied to crops including potato, cereal, apple, pear and leafy vegetables throughout the world since 1960. from the late 1980s, using these fungicides has caused much debate among regulators about their long-term effects on consumers and occupa...

Talang Queenfish (Scomberoides commersonnianuus) is relatively inexpensive fish with low consumption in Fars Province, South of Iran. In this research which was done in 2011, minced fish sausages were produced from mince and surimi of this species and some physicochemical attributes of the products were investigated during 60 days of cold storage at 4 °C. According to the results, free fatty ac...

In this paper, the effect of lightness on blackness preference of 216 black fabrics prepared by printing method is investigated. 18 observers including of 9 males and 9 females are asked to firstly rank order black fabrics with the same lightness values according to their preference. In the next step, observers are asked to define their blackness preference for blacks with different L values. R...

Abstract The umbu tree is an endemic species and found in the Brazilian semi-arid. Umbu highly appreciated for its socioeconomic importance significant diversity of quality attributes. This study aims to explore color-related variations between matrices, evaluate correlation main biometric attributes quality. With this, 14 matrices were explored at commercial ripening stage submitted colorimetr...
