The relationship between colour parameters and anthocyanins of four sweet cherry cultivars, Burlat, Saco, Summit and Van was studied. The colour (L*, a*, b*, chroma and hue angle parameters) and anthocyanins were analysed during two different years at two different ripening stages (partially ripe, and ripe, respectively). The cherries were analysed at harvest and after storage at 1.5 ± 0.5 C an...

Color names divide the fine-grained gamut of color percepts into discrete categories. A categorical transition must occur somewhere between the initial encoding of the continuous spectrum of light by the cones and the verbal report of the name of a color stimulus. Here, we used a functional magnetic resonance imaging (fMRI) adaptation experiment to examine the representation of hue in the early...

Lygus hesperus and L. lineolaris are two of the most economically important plant bugs in North America. Here we present results from field trials that evaluated effective trap characteristics for maximizing Lygus spp. and other herbivorous insects capture, while minimizing beneficial insect capture. The response of lygus bugs, several other key herbivore species and predators to hue (white, cl...

BACKGROUND Eosinophilic airway inflammation is observed in 10-30% of COPD subjects. Whether increased eosinophils or impairment in their clearance by macrophages is associated with the severity and frequency of exacerbations is unknown. METHODS We categorised 103 COPD subjects into 4 groups determined by the upper limit of normal for their cytoplasmic macrophage red hue (<6%), an indirect mea...

BACKGROUND Very few population-based cancer survival studies have been performed in Viet Nam. The aim of the present study was to estimate observed and relative cancer survival rates in populations of Phu Tho, Hanoi and Hue city. METHODS A retrospective-cohort study was performed for all 12 districts of Phu Tho province (semi-highland area in the north), eight districts of Hanoi city (Capital...

The aim of the study was to obtain normal values for the colour-arrangement test, Roth 28-hue desaturated. In 146 healthy non-smokers colour vision was tested monocularly. The subjects were divided into four age groups: 0-19, 20-39, 40-59, and 60-79 years. The overall error score for all groups was 54 +/- 24 (median +/- mean absolute deviation). The values for the 20-39 year group were signific...

OBJECTIVES To examine patterns of disease and injury in people living on boats in Hue City, Vietnam, and their relations to socioeconomic conditions, sanitary practices, disease prevention proficiency, and people's preference to continued living on boats. METHODS The subjects were 3737 people aged 5 years and over living on boats in Hue City, Vietnam. Diseases and injuries were diagnosed acco...

Expectations learned from our environment are known to exert strong influences on episodic memory. Furthermore, people have prior expectations for universal color labels and their associated hue space—a salient property of the environment. In three experiments, we assessed peoples’ color naming preferences, and expectation for color. Using a novel experimental paradigm, we then assessed free re...

The three variables of color vision are hue, saturat ion, and brightness. The characterist ic color differences along the spectrum which the color-normal sees are essentially concerned with hue. In measurements of wavelength discrimination the precise value of the just perceptible difference in wavelength at constant brightness is no doubt influenced by saturat ion differences, bu t the major f...
