We examined individual differences in the color appearance of nonspectral lights and asked how they might be related to individual differences in sensitivity to chromatic stimuli. Observers set unique hues for moderately saturated equiluminant stimuli by varying their hue angle within a plane defined by the LvsM and SvsLM cone-opponent axes that are thought to characterize early postreceptoral ...

A study was conducted to develop banana flour based edible film using Response Surface Methodology. A Central Composite Design was adopted in the optimization of banana flour and sodium alginate level for the development of edible film with 13 different runs and 5 trials of two similar centre points. Effects of banana flour (2-4% w/v) and sodium alginate (0.5-1.0% w/v) level on the thickness, m...

The colour changes that occur in kiwifruit during the dry process were experimentally studied in order to determine the magnitudes of the parameters for a corresponding colour change model. The drying experiments were carried out under five air temperatures of 40, 50, 60, 70 and 80°C, air velocity of 1.0 m/s and kiwifruit slice thickness of 4 mm. The colour parameters for the colour change of t...

PURPOSE To identify the most appropriate test for screening of early color vision abnormalities in uncomplicated juvenile diabetes. METHODS Enrolled in this study were 39 diabetic adolescents, characterized by optimal Early Treatment Diabetic Retinopathy Study criteria for visual acuity, transparent dioptric means and angiographically normal retinas. Color vision was examined with Standard Ps...

Common methods for quantification of colocalization in fluorescence microscopy typically require cross-talk free images or images where cross-talk has been eliminated by image processing, as they are based on intensity thresholding. Quantification of colocalization includes not only calculating a global measure of the degree of colocalization within an image, but also a classification of each i...

in this research, kiwifruits (hayward) were selected in two mass ranges (large and small). they were placed in one-liter glass bottles in the vicinity of the polyethylene sachets containing potassium permanganate nano-zeolite (0, 0.2, 0.4 and 0.8 g) and were stored in a germinator (5°c temperature and 30% relative humidity). then, the physicochemical properties of the fruits (soluble solid cont...

abstract this study was carried out in japan for evaluation of the relationship between phenolic compounds and skin color indices of 3 apples cultivars including ‘fuji’, ‘jonathan’ and ‘jonagold’, in 2006. in ‘jonathan’, l* (lightness) increased with decreasing red color of skin. in ‘jonagold’, chroma increased with increasing red color. but in ‘fuji’, there was no detectable difference between...

Visible/near infrared spectroscopy (Vis-NIRS) was used to monitor the yellow-fleshed kiwifruit (Actinidia chinensis Planch ‘Jintao’) ripening on two selected orchards along 13 weeks, from pre-harvest late harvest. Calibration models for several Internal Quality Attibutes (IQA) were built spectral data of 375 individual kiwifruit. The analyzed IQA L*, a* and b* CIELAB color space, hue angle, chr...
