The present study examined age-related differences in multisensory integration and the effect of spatial disparity on the sound-induced flash illusion--an illusion used in previous research to assess age-related differences in multisensory integration. Prior to participation in the study, both younger and older participants demonstrated their ability to detect 1-2 visual flashes and 1-2 auditor...
The utilization of a photo-induced synthon generated from N-phenyl glycine by an organic dye and visible light irradiation is disclosed. The intermediate could be coupled with either a radical or a nucleophile in a simple operation to afford several natural product-like compounds.
In this study human color constancy was tested for two-dimensional (2D) and three-dimensional (3D) setups with real objects and lights. Four different illuminant changes, a natural selection task and a wide choice of target colors were used. We found that color constancy was better when the target color was learned as a 3D object in a cue-rich 3D scene than in a 2D setup. This improvement was i...
A polarized Raman study of nanographite ribbons on a highly oriented pyrolytic graphite substrate is reported. The Raman peak of the nanographite ribbons exhibits an intensity dependence on the light polarization direction relative to the nanographite ribbon axis. This result is due to the quantum confinement of the electrons in the 1D band structure of the nanographite ribbons, combined with t...
Daylight historic spaces were the only source of lighting supplier and traditional architects to artistic style as a tool to increase the visual quality of space and concepts used. The light is considered to be integral elements of space and Iranian architectural pattern should also be followed. Lighting pattern of Natural light and provide criteria main research question is historic mosques. T...
In the production of flowers and ornamental plants, especially in the advanced greenhouse conditions, it is important to have a good light source and its accurate management. This study aimed to evaluate the effect of light quality on morphological and biochemical traits of two Marigold genotypes (Iranian-native and Gitana). This experiment was conducted in a completely randomized design with t...
Background and aims: Adequate lighting in work environments can increase productivity and concentration and reduce fatigue. Light and illumination studies have been done mainly in industrial environments, and public or administrative environments were less under consideration. The aim of this study was to evaluate the ultraviolet radiation and illumination level at Kerman Medical Sciences Uni...
One of the problems of natural yellow dyes (weld) is their low stability against light and their high fading rate. One of the main destructive factors in pale of color fibers and hand-woven carpet is the high-energy ultraviolet radiation which causes chemical bonds to break and optically damages of organic structures. In this study, the effect of some antioxidants (gallic acid, ascorbic acid) a...
