We propose a metric to predict the visibility of color halftone textures. This metric is represented by the critical viewing distance below which the halftone textures can be discriminated. It is intended to be used in the evaluation of the texture visibility of uniform color halftone patterns, which plays an important role in halftone design and optimization. The metric utilizes the visual thr...

bronze handle, believed at 3astet holding that time to be the handle of ,t of Mrs. Mary a menyet, another ceremonial Draper, I9I5 object, but it is obvious now that it belonged to an aegis instead, and undoubtedly to an aegis of Isis, since it is she who is represented in the decoration on its upper part. The counterpoise is almost identical in shape and decoration with the one at the back of t...

We investigate determinants of the pattern of recent migration of Alaska Natives between rural homelands and urban areas. A review of the literature on moving in the North American North suggests that economic opportunities draw migrants, although such opportunities must be viewed in the context of the mixed subsistence-cash economy prevailing in rural areas of the region. Consequently, we mode...

Recent research on the solution-based fabrication of inorganic thin films and organic/inorganic nanolaminates has ranged from fundamental studies of biomineralization to the synthesis of novel materials and devices. Highlights include the elucidation of how biogenics and model organic nucleants affect the form of the biomineral; synthesis of mesoscale nanocomposite films by surfactant templatin...

This paper reports new insights on the role of the inorganic composition of Bone char (BC) on its sorption properties for the removal of heavy metals Cd, Ni, and Zn ions from aqueous solution. In particular, we showed the importance of both composition and surface chemistry of BC on its sorption properties for the removal of these metal ions in aqueous solution. Results of physicochemical chara...
