Abstract:
... Although there is widespread agreement about the need to reduce teenagers’ consumption of sugar-sweetened beverages, banning these drinks from the school environment is not always feasible. In this paper, we tested whether increasing the assortment of healthier alternatives and clearly labelling them as healthy by means of traffic light coding qualifies as an alternative approach to reduce the con ...

Abstract:
... Crossmodal correspondence is of scientific and commercial interest in regard to the packaging of food and beverages. Research has shown that colors and shapes can be associated with certain aromas, but these interactions have been less extensively studied with authentic visual stimuli (i.e., packaging), or with complex food odors in a matrix. This study investigated odor-color-shape crossmodal int ...
... Particle mixing is a very important process in many industrial reactors. It is important to consider how to quantify the particle mixing behavior accurately under different conditions. In this paper, the drawbacks of traditional mixing indexes, such as Lacey index are discussed, and then a novel particle mixing index, without grid dependency and particle color dependency was proposed based on the ...
... Chinese traditional costumes have been recognized as one of the most influential sources for Western designers to obtain oriental inspirations and create Asian chic, especially the dominant colors and design style. In this paper, an effective color clustering method based on Mean shift clustering algorithm is developed for Chinese traditional costumes image. The proposed method consists of four st ...
... The remarkable diversity of color in nature remains largely unexplained. Recent studies on birds show how historical reconstructions, the identification of genes affecting color differences, and an increased understanding of the underlying developmental mechanisms are helping to explain why species are the color they are. ...
... The development of luminescent materials for anticounterfeiting and encryption is of great importance. Herein, we develop a multistimuli-responsive luminescent material, Na₂CaGe₂O₆:Pb²⁺/Er³⁺, and use it to print luminescent images. The photoluminescence and upconversion luminescence of these images show different patterns and colors under different stimuli. The photostimulated luminescence (PSL) o ...
... The purpose of this study was to identify the impact of different discriminative features of stimuli in a P300 brain-computer interface paradigm on overall performance and evoked potentials. It has been shown that stimuli sets with a greater number of discriminative features yield better target selection accuracy. Target selection accuracy was significantly higher for the stimuli that differ from ...
... Owing to its benefits to reducing paper production and consumption, ink-free rewritable paper has attracted great attention and it is desirable to develop rewritable paper based on its low-cost, robust, and environmentally benign color switching systems. Herein, we report the fabrication of a rewritable paper based on novel poly(vinylpyrrolidone)/hexatungstic acid (HTA) hybrids with fast dual-mode ...

Abstract:
... Polymethylmethacrylate matrix has been developed as an analytical device for visual and spectrophotometric determination of malachite green. Based on the studied effects of different pH levels, temperature, contact time and diverse ions, optimum analysis conditions have been established. For malachite green, the calibration graph was linear in the range of 0.5–30 mg·L⁻¹ in the samples with the det ...

Abstract:
... Ce:YAG transparent ceramics for white LEDs devices suffered from the issues of low light extraction, narrow luminous angle and poor thermal performance. In this paper, the different textures were grown on the surface of Ce:YAG transparent ceramics by a simple mechanical grinding to enhance the light extraction, and the luminous angle of 4π was realized by the novel design of hexahedral ceramic tub ...
... The current study reports on a novel computerised colour vision test employing static and dynamic stimuli. The aim of the study was to assess if static and dynamic stimuli result in comparable chromatic discrimination thresholds when participant’s age is taken into account. Participants (n = 20) were 21 to 77 years old, had normal colour vision and no history of any eye disease. They all participa ...

Abstract:
... Colour vision depends on sufficient ambient light and becomes ineffective at a particular low light intensity. It is not known how decapod crustaceans see colour in dim light. In the present study we investigated the colour vision threshold in larvae of the giant freshwater prawn Macrobrachium rosenbergii in a tank under natural illumination. Plastic beads of different colours (blue, red, yellow a ...
... The mixing process of binary granular systems in a short rotating drum was investigated by performing discrete element simulations. The drum was asymmetrically operated with the left end wall being fixed and the right one rotated with the side wall. The modeled granular materials were made of particles with same size and density but different colors (red and yellow). These yellow and red particles ...
... Within the past several decades, resource trade‐offs have emerged as the commonly accepted explanation for how carotenoid‐based coloration links to individual performance. However, the literature on carotenoid signalling is inconsistent in how carotenoid resource trade‐offs are defined, assessed and interpreted. We provide a clear statement of the resource trade‐off hypothesis for explaining the h ...
... Optimum conditions for the formation and extraction of a slightly soluble ion associate of diphenhydramine with the anionic complex molibydenum–gallein were determined. The ternary complex was extracted with butanol at pH 4–7. In the presence of diphenhydramine, the color strength became stronger, which was manifested in the absorption spectra as hypsochromic and bathochromic shifts. Some physicoc ...
... The development of fingerprints in blood on a dark-coloured surface can be difficult. Contrast between the bloodmark and the surface can be difficult to achieve using photography and chemical reagents. The use of haem-reagent ortho-Phenylenediamine (OPD) and Zar-Pro™ strips in the enhancement of bloody impressions were investigated. Depletions of bloodmarks were deposited on black ceramic tiles an ...
... Ocean colour sensors traditionally are of fixed spectral channel systems with specified bandwidth of about 20 nm in the visible region and about 40 nm in Near Infrared region. In these systems, it is known that a radiometric error of 1% in the measurement of top of the atmosphere signal may lead to an error of 10% in the retrieved ocean upwelling radiance. In this paper we investigated the range o ...
... Iridescence, a change in hue with viewing or illumination geometry, is a common feature of colour patterns in nature, though its significance remains elusive. Recent studies of floral iridescence reveal its functional versatility in enhancing the detection and discrimination of resources by insect viewers, as well as augmenting higher-level processes of memory and perception. Coupled with a known ...
... We describe a method to quickly evaluate soil esterase activity using p‑nitrophenyl valerate as the substrate. Unwanted coloration of the control samples was suppressed by cooling. Esterase activity can be evaluated using arbitrary amounts of soil. Sample dispensation was simplified and the number of examinations per soil sample reduced. ...
