The article discusses normal incidence sound absorption by aluminium foam manufactured with powder metallurgy technology.Aluminium foams with different surface morphologies were obtained by varying the type of precursor and adding filler materials during the foaming process.The sound absorption coefficients found for these Hair Care aluminium foams
Abstract Background Across the Metazoa, similar genetic programs are found in the development of analogous, independently evolved, morphological features.The functional significance of this reuse and the underlying mechanisms of co-option remain unclear.Cephalopods have evolved a highly acute visual system with a cup-shaped retina and a novel refra
