In recent years, it has been discovered that the endemic earthworm Carpetania elisae (formerly Hormogaster elisae) consists of a complex of at least six cryptic species. Studying the relationships between these new cryptic species and other soil[...]texto impreso
Annual and seasonal water variability is predicted to intensify due to climate change. River basins lacking institutional capacity, such as treaties, to deal with environmental change may experience political tensions. Using the 1948–2008 countr[...]texto impreso
Several sociodemographic phenomena have changed family organization in Spain over the last few decades, where less structured forms than the traditional nuclear family have gained in importance. In view of the importance of children’s and adoles[...]texto impreso
The role of opinion leadership to develop positive loyalty effects in the arts services has received little attention. The objectives of this paper are: first, to test the influence of opinion leadership between service attributes and loyalty; a[...]texto impreso
Dolomite in caves: Recent dolomite formation in oxic, non-sulfate environments. Castañar Cave, Spain
Dolomite is a common mineral in the rock record but rare in recent superficial environments. Where it does occur, it is related to anoxic, sulfate-rich environments and microbial activity. The occurrence of some dolomite deposits in caves, howev[...]texto impreso
A numerical method to detect objects buried in a medium by surface thermal measurements is presented. We propose a new approach combining the use of topological derivatives and Laplace transforms. The original optimization problem with time-depe[...]texto impreso

Caves are natural laboratories to investigate evolutionary processes in the ocean. In contrast to the many described lineages of cave exclusive crustaceans and annelids, very little is known about cave scalidophorans. We here describe two new sp[...]texto impreso
Quantifying the action of antibiotics on biofilms is essential to devise therapies against chronic infections. Biofilms are bacterial communities attached to moist surfaces, sheltered from external aggressions by a polymeric matrix. Coupling a d[...]texto impreso
Moratti, Stephan ; Mendez Bertolo, Constantino ; Pozo Guerrero, Francisco del ; Strange, Bryan | Elsevier | 2014To perceive a coherent environment, incomplete or overlapping visual forms must be integrated into meaningful coherent percepts, a process referred to as "Gestalt" formation or perceptual completion. Increasing evidence suggests that this proces[...]texto impreso
This paper is part of a program that aims to understand the connection between the emergence of chaotic behaviour in dynamical systems in relation with the multi-valuedness of the solutions as functions of complex time tau. In this work we consi[...]texto impreso
We analyze the dynamics of a reaction–diffusion equation with homogeneous Neumann boundary conditions in a dumbbell domain. We provide an appropriate functional setting to treat this problem and, as a first step, we show in this paper the contin[...]texto impreso
In this work we continue the analysis of the asymptotic dynamics of reaction–diffusion problems in a dumbbell domain started in [J.M. Arrieta, A.N. Carvalho, G. Lozada-Cruz, Dynamics in dumbbell domains I. Continuity of the set of equilibria, J.[...]texto impreso
In this paper we conclude the analysis started in [3] and continued in [4] con- cerning the behavior of the asymptotic dynamics of a dissipative reactions di_usion equation in a dumbbell domain as the channel shrinks to a line segment. In [3], w[...]texto impreso

In this Note we study the asymptotic behavior of reaction diffusion equations with nonlinear boundary conditions. We obtain balance conditions between the reaction term and the nonlinear flux term which imply boundedness of solutions or blow-up [...]texto impreso
We use upper semifinite hyperspaces of compacta to describe "-connectedness and to compute homology from finite approximations. We find another connection between "- connectedness and the so called Shape Theory. We construct a geodesically compl[...]texto impreso
