This study aimed to evaluate barbatimão bark extracts as a feed additive and substitute for lasalocid sodium (LAS) feedlot lambs. Lambs were distributed into three treatments: LAS (0.018 g of sodium), DBB (1.500 dried milled bark), BHE (0.300 hydroalcoholic extract). There was no effect (p = 0.32) the inclusion on average daily gain. Inclusion in lamb diets reduced < 0.05) fatness score comp...

BACKGROUND We sought to investigate the association between blood pressure levels and prevalence of acquired color vision impairment in middle-aged Japanese men. METHODS Participants underwent color vision testing, ophthalmological examination, standardized interview, physical record examination, and venous blood examination. Cardiovascular disease risk factors were determined based on blood ...

Traditional trichromatic theories of color vision conclude that color perception is not possible under scotopic illumination in which only one type of photoreceptor, rods, is active. The current study demonstrates the existence of scotopic color perception and indicates that perceived hue is influenced by spatial context and top-down processes of color perception. Experiment 1 required observer...

In this paper, we proposed the digital watermarking for a color image. In order to embed watermark signal, we consider the characteristics of HVS(human visual system) and focus on the relatively insensitive components of a color image. In YCrCb color space, Y component is achromatic luminance and both Cr and Cb components are chromatic color. At the Cr-Cb chrominance plane, an angle of a pixel ...

Panel tests of color vision (eg FM100-Hue test) lack a common quantitative method for the scoring of cap arrangements. We describe a scoring method applicable to all panel tests that makes use of a novel technique to analyze test cap data, namely the calculation of a moment of inertia from the Color Difference Vectors (CDVs) of any arrangement pattern. Using the Farnsworth D-15 panel, as an exa...

In the present work the reflection behavior and the color appearance of acrylic yarns, as pile yarns used in carpet and pilled fabrics, are considered along their lengths as well as their cross- sections. Differences between longitudinal and cross-sectional reflection behaviors of yarns are measured in different yarn densities and hues and explained by the geometric model. The results of experi...
