On soil-structurae interaction in large non-slender partially buried structures.

[EN]This paper addresses the seismic analysis of a deeply embedded non-slender structure hosting the pumping unit of a reservoir. The dynamic response in this type of problems is usually studied under the assumption of a perfectly rigid structure using a sub-structuring procedure (three-step solution) proposed specifically for this hypothesis.

Influence of loggerhead egg agregation on survival: why does single eggs buried into natural sand dye in few days?

[EN] The incubation is an essential life period for oviparous species that very often experiences a high mortality. In some reptile species the number of eggs that develop together in the incubation chamber affects survival and hatchling phenotype. Sea turtle eggs develop in underground locations on sandy beaches in large masses that usually have more than 80 eggs. Natural egg mortality seems to vary among species and for the sensitive leatherbacks, external eggs seems to survive better than internal ones within the nest.

In loving memory: Escritura última y memoria en los cementerios ingleses de Canarias

[ES] El estudio de las inscripciones que se conservan en los tres cementerios ingleses de Canarias, así como de los propios monumentos funerarios en los que estas se inscriben, permite un acercamiento al ars moriendi, pero también a los mecanismos de autorrepresentación de los miembros de la comunidad británica radicada en Canarias cuyos restos reposan en estas necrópolis. El presente estudio pretende analizar estas escrituras últimas en el contexto de una historia social de la cultura escrita en Canarias que cuenta, como elemento de diferenciación con respecto a otras regiones españolas, con una importante presencia británica, evidenciada en la mayor concentración de cementerios protestantes de todo el país.

Two-dimensional numerical approach for the vibration isolation analysis on thin walled wave barriers in poroelastic soils.

[EN]This paper is concerned with the vibration isolation efficiency analysis of total or partially buried thin walled wave barriers in poroelastic soils. A two-dimensional time harmonic model that treats soils and structures in a direct way by combining appropriately the conventional Boundary Element Method (BEM), the Dual BEM (DBEM) and the Finite Element Method es developed to this aim.
