We present a practical and inexpensive method for creating physical objects that cast different color shadow images when illuminated by prescribed lighting configurations. The input to our system is a number of lighting configurations and corresponding desired shadow images. Our approach computes attenuation masks, which are then printed on transparent materials and stacked to form a single mul...

the research argues that the ending divine attributes of the quranic verses are related semantically to the verses’ theme. according to the content of the quranic verses, supported by some commentators, the ending divine attributes of the verses have such a deep semantic relationship with the verse content that if we abandon the ending attributes, some disorder is made in the verse theme. this ...

conclusions in lighting conditions, most of t-res was isomerized to the other isomer cis-resveratrol. t-res is unstable in alkali ph and when exposed to light. t-res was quite stable at other conditions, and several freeze-thaw cycles did not have any effect on its stability. results our findings revealed that t-res was quite stable in different temperatures ranging from -70 °c to 25 °c, and ac...

in order to study the effect of light quality and quantity on morphological and physiological characteristics of two late and early maize (zea maize l.) s.c., an experiment was conducted in greenhouse conditions, ferdowsi university of mashhad, iran, during 2008. the experiment was carried out factorial based on randomized complete block design with six treatments and three replications. differ...
