    A mechanical model for small vibrations of an elliptic spider web

    No full text
    A continuous membrane model for the infitesimal deformation of a spider web was recently proposed by Morassi, Soer and Zaera (2017) in the context of axially-symmetric webs. In this note, we derive an extension of the model to spider webs with an elliptic shape. The analysis of the tensile pre-stress acting on the referential configuration and the free transverse vibration of a supported elliptical web are studied in detail

    New raphitomine gastropods (Gastropoda: Conidae: Raphitominae) from the South-West Pacific

    No full text
    Based on material stored in Muséum National d’Histoire Naturelle (MNHN) eight new species collected from bathyal depths in South West Pacific archipelagos (Solomon Islands and Fiji) are described. The new species belong to the rather poorly known genera Acanthodaphne Bonfitto et Morassi, 2006, Acamptodaphne Shuto, 1971, Buccinaria Kittl, 1887, Cryptodaphne Powell, 1942 and Mioawateria Vella, 1954 all belonging to subfamily Raphitominae Bellardi, 1875 in the family Conidae Fleming, 1822. Acamptodaphne eridmata sp. nov. has a broad distribution being reported from the Solomon Islands and Taiwan. Finding of the new species here discussed in South West Pacific archipelagos provides a significant extension to the previously known geographical range of these raphitomine genera
