Plant extracts are extensively researched as a source of green corrosion inhibitors. Herein, we report on a highly efficient and thermally stable corrosion inhibitor from the stem extract of high-altitude shrub Berberis aristata. The corrosion inhibition efficiency (IE) of the extract was tested in 1.0 M H2SO4 for the corrosion protection of mild steel (MS) by using gravimetric and electrochemi...

Both conspicuous plumage ornamentation and song are well‐known examples of sexually selected traits, but their interrelationship is not well known, perhaps in part because confounding factors, including interspecific variation ecology, habitat, morphology, type ornamentation. Here, using a phylogenetic comparative approach the 69 species with available information (i.e. 96% all 72 species), I e...

Modular bivariate quadratic functions are used to procedurally generate textures that resemble ornamentation, skin, scales, feathers, and textiles. They are easy to implement and particularly suited to parallel execution as a pixel shader. A prototype browser-based procedural texture generator with an interface suitable for use by non-mathematicians such as designers and artists is described.

A new shallow-water squat lobster, Galathea ryuguu, is described on the basis of material obtained from a colony of unidentified sea fan of the genus Muricella Verrill, 1868. The new species is most closely allied to G. squamea Baba, 1979, but is distinguished by the ornamentation and armature of the carapace, third maxilliped, and ambulatory legs.
