BACKGROUND As Earth warms, temperate and subpolar marine species will increasingly shift their geographic ranges poleward. The endemic shelf fauna of Antarctica is especially vulnerable to climate-mediated biological invasions because cold temperatures currently exclude the durophagous (shell-breaking) predators that structure shallow-benthic communities elsewhere. METHODOLOGY/PRINCIPAL FINDI...

We review approaches to the chunking and UpWriting of local descriptors.

Abstract After introduction, the invasive bivalve dreissenids became key species in biota of Lake Balaton, largest shallow lake Central Europe. The contribution dreissenid soft tissue and shell, as biotic phases, element distribution its interaction with water upper sediment phases were examined two basins different trophic conditions spring autumn. Six metals (Ba, Cu, Fe, Mn, Pb, Zn) detected ...

This paper presents a study on nonlinear asymmetric vibrations in shallow spherical caps under pressure loading. The Novozhilov’s shell theory is used for modeling the structural strains. A reduced-order model developed through Rayleigh–Ritz method and Lagrange equations. equations of motion are numerically integrated using an implicit solver. bifurcation scenario addressed by varying external ...

Zn(x)Cd(1-x)Se/C core/shell nanocrystals with 31-39 nm semiconducting core and 11-25 nm carbon shell were synthesized from solid state precursors in large scale amounts. A mixture of spherical and tripod nanostructures were obtained only in the one-step reaction (ZC3), where the Zn- and Cd-precursors were reacted simultaneously, rather than in the two step reactions (ZC1 and ZC2), where largely...

curls and curves of a shell interweave its various strain modes and link them together. this interactional behavior has yet frustrated all attempts for the construction of shell templates, which needs for an individual element test in traditional approaches. such a test fails to work for shell elements and must be reconstructed. in this paper, it is tried to study shell interactional behavior a...
