this study was conducted to evaluate the quality of the red flesh apples and golab cultivars. two iranian red flesh apples from shahroud and four golab cultivars as well as ‘gala’ as control from damavand were selected in summer 2012. fruit physical characteristics including length, diameter, fresh weight and dry weight, firmness, color and their parameters were evaluated for each cultivar. the...

The mother or daughter of a male with an X-chromosome-linked red/green color defect is an obligate carrier of the color deficient gene array. According to the Lyonization hypothesis, a female carrier's defective gene is expressed and thus carriers may have more than two types of pigments in the L/M photopigment range. An open question is how a carrier's third cone pigment in the L/M range affec...

BACKGROUND Color blindness is a common X-linked genetic disorder. However, most of color blinds remain undetected due to absence of proper screening. Our study was to determine the prevalence of red-green color vision defects among Manipuri Muslim males and females. The study could help in decreasing birth of children with this disorder as Muslims commonly perform consanguineous marriage among ...

Protanomaly is a common abnormality of color vision in which the long wavelength sensitive cone is lacking. Protanomalous observers are trichromatic with reduced ability to discriminate colors in the red-green part of the spectrum because the photopigments that mediate discrimination in this range are abnormally similar differing in one of two ways; first, by only a few nanometers in peak sensi...

reducing the number of colors in an image while preserving its quality, is of importance in many applications such as image analysis and compression. it also decreases memory and transmission bandwidth requirements. moreover, classification of image colors is applicable in image segmentation and object detection and separation, as well as producing pseudo-color images. in this paper, the kohene...

We present measurements of the color and luminosity dependence of galaxy clustering at z ∼ 1 in the DEEP2 Galaxy Redshift Survey. Using volume-limited subsamples in bins of both color and luminosity, we find that: 1) The clustering dependence is much stronger with color than with luminosity and is as strong with color at z ∼ 1 as is found locally. We find no dependence of the clustering amplitu...

introduction: the effects of accidents vary from minor injuries to fatalities and from insignificant damage to very severe damage to the environment and property. in order to prevent accidents in the work place, the root causes of and events should be identified using a systematic method and the results should be published. the current study aims to investigate the given causes of an accident i...
