pomegranate (punica granatum) is an important fruit crop cultivated for fruit and processing in the iran. delaying fruit harvest of pomegranate may increase fruit losses due to fruit cracking; however, early harvest may influence physical and biochemical indices of fruit. an experiment was carried out in 2011 at ‘baghmalek’ (north west of ahwaz, khuzestan province, iran) to determine the effect...

gundelia tournefortii l. is a well known plant in mountains of iran and is found all over the country. it traditionally has some medicinal applications. in this research, gundelia tournefortii l. seed was studied as a source of edible oil. oil was extracted with immersion method using diethyl ether as a solvent. acidity, saponification, ester, iodine, peroxide and refractive indices, average mo...

acquired color deficiency in the tritan axis in parkinson’s disease has already been reported, manifesting itself as impaired performance in various visual tasks. however, its clinical significance has always been controversial. in this study we evaluated the performance of parkinson s disease patients in lanthony 15-desaturated clinical test and for the first time, compared it with the standar...

BACKGROUND Tetrachloroethylene (PCE; or perchloroethylene) has been implicated in visual impairments among adults with occupational and environmental exposures as well as children born to women with occupational exposure during pregnancy. OBJECTIVES Using a population-based retrospective cohort study, we examined the association between prenatal and early childhood exposure to PCE-contaminate...

With high temperature-heat treatment, the dimensional stability and durability of wood is improved and wood color is darkened as well. In this paper, alder birch wood (Betula alnoides) was treated by the ThermoVacuum Treatment (TVT). The changes of wood color parameters and the chemical composition were determined by the CIE1976 L*a*b* method and the chemical analysis method, respectively. The ...

Naive observers viewed a sequence of colored Mondrian patterns, simulated on a color monitor. Each pattern was presented twice in succession, first under one daylight illuminant with a correlated color temperature of either 16,000 or 4000 K and then under the other, to test for color constancy. The observers compared the central square of the pattern across illuminants, either rating it for sam...

In this paper, the historical infrared (JHK) data compiled from 22 publications are presented for 3C 279 and 4C 29.45. Relations between color index and magnitude and between color-color indices are discussed. (J-K) is found closely correlated with (J-H) while (J-H) is almost not correlated with (H-K), which is perhaps due to two facts of (1) (J-K) shows wider distribution than (J-H) and (H-K) ...

We have investigated the use of spectral imaging for multi-color analysis of permanent cytochemical dyes and enzyme precipitates on cytopathological specimens. Spectral imaging is based on Fourier-transform spectroscopy and digital imaging. A pixel-by-pixel spectrum-based color classification is presented of single-, double-, and triple-color in situ hybridization for centromeric probes in T24 ...

Visual inspection of wholesome and unwholesome chicken carcasses with a novel two-narrowband color-mixing technique for optically enhanced binoculars is simulated. From mean spectra of wholesome, airsacculitis (air-sac), cadaver, inflammatory process (IP), septicemia-toxemia (septox), and tumor chicken samples, 10 nm wave-band pairs are selected using color difference and chromaticness differen...

potato (Solanum tuberosum L.) genotypes exhibit significant variation for chip color across different storage regimes. Lines that maintain light chip color after long postharvest storage durations and low storage temperatures are desirable to the potato industry. Since storage regimes vary among growers and processors, lines that exhibit stable chip performance across various storage regimes ha...
