Scalar and tensorial cosmological perturbations generated in warm inflationary scenarios whose matter-radiation fluid is endowed with a viscous pressure are considered. Recent observational data from the Wilkinson Microwave ...

The evaluation of treatment costs is one of the aspects which need more attention for the complete introduction of electrochemical reactors as an attractive alternative in the field of advanced oxidation processes. This ...

The eastern boundary of the Chile-Peru Current System constitutes one of the most biologically productive ecosystems in the world, due largely to coastal upwelling and the horizontal advection of nutrients. In this ecosystem, ...

To identify motifs involved in oligomerization of the gap junction protein Cx26, we studied individual transmembrane (TM) domains and the full-length protein. Using the TOXCAT assay for interactions of isolated TM α-helices, ...

In this work we study the dark energy problem by adopting an holographic model proposed recently in the literature. In this model there has been postulated an energy density ρ~R, where R is the Ricci scalar curvature. Under ...

Chile is the largest producer and exporter of blueberries in the southern hemisphere. During the 2006-2007 growing season, blueberry production increased in Chile as a result of an expansion of the planted area, reaching ...
