Common fixed points for multimaps in metric spaces
(SpringerOpen, 2010)
We discuss the existence of common fixed points in uniformly convex metric spaces for singlevalued pointwise asymptotically nonexpansive or nonexpansive mappings and multivalued nonexpansive, ∗-nonexpansive, or ε-semicontinuous ...

A trap transporter for pyruvate and other monocarboxylate 2-oxoacids in the cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2010)
In the cyanobacterium Anabaena sp. strain PCC 7120, open reading frames (ORFs) alr3026, alr3027, and all3028 encode a tripartite ATP-independent periplasmic transporter (TRAP-T). Wild-type filaments showed significant ...

Catabolic function of compartmentalized alanine dehydrogenase in the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2010)
In the diazotrophic filaments of heterocyst-forming cyanobacteria, an exchange of metabolites takes place between vegetative cells and heterocysts that results in a net transfer of reduced carbon to the heterocysts and of ...

An iterative procedure to solve a coupled two-fluids turbulence model
(EDP Sciences, 2010)
This paper introduces a scheme for the numerical approximation of a model for two turbulent flows with coupling at an interface. We consider the variational formulation of the coupled model, where the turbulent kinetic ...

Fixed points of single- and set-valued mappings in uniformly convex metric spaces with no metric convexity
(SpringerOpen, 2010)
We study the existence of fixed points and convergence of iterates for asymptotic pointwise contractions in uniformly convex metric spaces. We also study the existence of fixed points for setvalued nonexpansive mappings ...

On a parabolic-elliptic chemotactic model with coupled boundary conditions
(Elsevier, 2010-10)
This paper deals with a nonlinear system of parabolic-elliptic type with a logistic source term and coupled boundary conditions related to pattern formation. We prove the existence of a unique positive global in time ...

Aplicación de XFuzzy 3 al procesado de imágenes basado en reglas
(Universidad de Huelva European Society for Fuzzy Logic and Technology, 2010)
Los entornos de desarrollo de sistemas fuzzy se han empleado normalmente para diseñar sistemas de control y de toma de decisiones pero apenas para diseñar sistemas de procesado de imágenes, a pesar de que este campo cuenta ...

Magnetic field induced inversion in the effect of particle size on powder cohesiveness
(AIP Publishing, 2010-07)
Experimental measurements are reported on the tensile yield stress of magnetofluidized beds of fine magnetic powders operated in the cross-flow configuration. In the absence of externally applied magnetic field the yield ...

On the Design of a Domain Specific Language for Enterprise Application Integration Solutions
(Universidad Rey Juan Carlos, 2010-06-29)
Enterprise application integrations involve the participation of several existing applications with which the integration solution exchanges data over LANs and the Internet. In these scenarios, operations might occasionally ...
