    Notes: We report here on the growth of epitaxial YMnO3 thin films on SrTiO3 single crystallinesubstrates. We show that depending of the choice of the substrate orientation or use of suitable(metallic) buffer layer, the epitaxial texture of the YMnO3 thin films as well as its crystallographicphase (orthorhombic or hexagonal) can be selected. Antiferromagnetic YMnO3 films have been alsogrown on ferromagnetic SrRuO3 epitaxial layers. Magnetic measurements show the existence of anexchange bias in orthorhombic films

    Notes: Survival and recovery rates were obtained for small-spotted catshark Scyliorhinus canicula in the Cantabrian Sea (north of Spain) based on tagging data. A total of 7656 specimens were tagged from 1993 to 2001. Recovery models for multiyear tagging studies were applied using the programme Mark. The best model fitted was achieved considering constant survival and recovery rates following the Brownie parameterization. The outputs were a survival rate (S) 0·89 and a recovery rate (f) 0·006. The reduced parameterization (S and r) provided very similar results, 0·89 and 0·06 respectively. The total finite mortality estimated was therefore Z = 0·11.

    Notes: This paper presents a crack analysis of linear magnetoelectroelastic materials subjected tostatic loading conditions. To this end, an efficient boundary element method (BEM) is developed.Unlike many previous investigations published in literature, two-dimensional (2-D) linearmagnetoelectroelastic materials possessing fully coupled piezoelectric, piezomagnetic andmagnetoelectric effects are considered in this paper. A combination of the displacement BEM andthe traction BEM is used in the present formulation. The displacement BEM is applied for theexternal boundary of the cracked solid, while the traction BEM is used for the crack-faces. Aregularization technique is implemented to compute the strongly singular and hypersingularboundary integrals in the BEM. The electric displacement intensity factor (EDIF), the magneticinduction intensity factor (MIIF), the stress intensity factors (SIF), the mechanical strain energyrelease rate (MSERR) and the total energy release rate (TERR) are evaluated directly from thecomputed nodal values at discontinuous quarter point elements placed next to the crack tip. Theaccuracy of the BEM is verified by analytical solutions known in literature. Results are presented fora branched crack in a bending specimen subjected to combined magnetic-electric-mechanicalloading conditions
