BACKGROUND Simulcheck evaluates Colour Simulation Tools (CSTs, they transform colours to mimic those seen by colour vision deficients). Two CSTs (Variantor and Coblis) were used to know if the standard Simulcheck version (direct measurement based, DMB) can be substituted by another (RGB values based) not requiring sophisticated measurement instruments. METHOD Ten normal trichromats performed ...

study of morphological traits of red fleshed apples is a critical step to improve the quality andcommercializing of them. in order to study genetic diversity of iranian red fleshed apples, a total of 17morphological characteristics were assessed for eight genotypes of red- fleshed (‘haji qermez’, ‘goushtqermez’, ‘shahroud-10’, ‘arous gousht qermz’, ‘b.9’, ‘qazvin 1, 2, 3’) and 12 iranian and fo...

development of a suitable method for color sorting of agricultural products such as: tomato, apple and orange, based on surface reflection and image formation was the goal of this research. a suitable scheme of color differentiation using an optic head and electrical processing circuitry for separating red from green and other colors is presented. a photo-conductive transducer, electrical resis...

INVESTIGATIONS made by Motokawa and Mita (1942), Adrian (1945), Gastaut (1949), Johnson (1949), Schubert and Bornschein (1952), Armington (1952), Armington, Johnson, and Riggs (1952), Bornschein (1953), Burian (1954), and Auerbach and Burian (1955), and by other investigators, have revealed that-under suitable conditions of examination-the human electroretinogram (ERG) normally consists of a ph...

The red color of fruit is an attractive plant trait for consumers. Plants with color-faded fruit have a lower commercial value, such as 'Red Bartlett' pears (Pyrus communis L.) that have dark-red fruit in the early stages of fruit development that subsequently fade to red-green at maturity. To identify the reason for color fading, we first analyzed the anthocyanin content of peel from 'Red Bart...

color had a special role in the human life. today psychologists use colors to do researches and recognition of people's mental characteristics. luscher's color test is further one of many well known tests. in the literature world a poet shows his way of thinking by using some special words. this research uses the luscher color test and measures the person's psychophysical state based on samih a...

sensitivity of tomato fruits to chilling injury limits its storage and marketability. this study investigated the effect of hot water treatment (hwt) on reducing the consequences of chilling injury (ci) with respect to quality attributes of tomatoes during storage. tomatoes were harvested at three ripening stages: mature green, pink, and red; dipped in hot water at 45°c for 15 min; and stored a...
