| The objective of this study is to define a reliable tool for dimensioning of adhesively bonded assemblies, particularly for marine and underwater applications. This paper presents experimental and numerical results, which describe the non-linear behaviour of an adhesive in a bonded assembly for various loadings. A modified Arcan fixture, well-suited for the study of the behaviour of bonded metal-metal assemblies, was developed in order to focus on the analysis of the behaviour of the adhesive in thin films. The edge effects are minimised by using an appropriate design of the substrates so that experimental results give reliable data. To analyze the kinematics of the deformation of the adhesive joint non-contact extensometry techniques were employed. Thus,... |

| La mayoría de los peces de arrecifes poseen un estadio larval pelágico durante el cual pueden ser transportados largas distancias. La inferencia de estos patrones de conectividad a partir de estudios genético-poblacionales, ha cobrado gran auge debido a su utilidad en el diseño de áreas marinas protegidas. Este trabajo se propone analizar la influencia de las posibles barreras físicas, la biología de la especie y sus potenciales de dispersión, en la estructura genética de Stegastes partitus y brindar elementos al esclarecimiento de esta problemática en el archipiélago cubano. Se colectaron individuos de cinco localidades del archipiélago cubano: Los Canarreos y La Bajada, en la región Suroccidental; y por el Norte: Cayo Coco, Los Colorados, y... |

| We present the key feature of a quantitative food web model for the shelf and slope waters off Sierra Leone, constructed using the Ecopath with Ecosim software. Three periods are represented: 1964, based on data from the Guinean Trawling Survey, complemented with field data on lower trophic levels gathered in the late 1950/early 1960s and published by A.R. Longhurst; 1978, for which fish abundance data from an ex-USSR survey exist, along with related, scattered fisheries information; and 1990, for which a fair amount of fisheries data exist, along with the results of a Spanish trawl survey. Demersal fish biomass appears to have declined linearly from 1964 to 1990, due to the massive increase of the catches of distant water fleets operating in Sierra Leone,... |
