Earth observation satellites produce large amounts of images/data that not only must be processed and preserved in reliable geospatial platforms but also efficiently disseminated among partners/researchers for creating derivative products through collaborative workflows. Organizations can face up this challenge in a cost-effective manner by using cloud services. However, outages and violations of integrity/confidentiality associated to this technology could arise. This article presents FedIDS, a suite of cloud-based components for building dependable geospatial platforms. The Fed component enables organizations to build shared geospatial data infrastructure through federation of independent cloud resources to withstand outages, whereas IDS avoids violations of integrity/confidentiality of images/data in sharing information and collaboration workflows. A FedIDS prototype, deployed in Spain and Mexico, was evaluated through a study case based on a satellite imagery captured by a Mexican antenna and ...

Fidgetin is a member of the AAA protein superfamily with important roles in mammalian development. Here we show that human Fidgetin is a potent microtubule severing and depolymerizing the enzyme used to regulate mitotic spindle architecture, dynamics and anaphase A. In vitro, recombinant human Fidgetin severs taxol-stabilized microtubules along their length and promotes depolymerization, primarily from their minus-ends. In cells, human Fidgetin targets to centrosomes, and its depletion with siRNA significantly reduces the velocity of poleward tubulin flux and anaphase A chromatid-to-pole motion. In addition, the loss of Fidgetin induces a microtubule-dependent enlargement of mitotic centrosomes and an increase in the number and length of astral microtubules. Based on these data, we propose that human Fidgetin actively suppresses microtubule growth from and attachment to centrosomes.

Considering Michel de Certeau's ideas about spatial stories, my objective is to analyze the exiled subject and the construction of collective memory (in Maurice Halbwachs's terms) in Merce Rodoreda's Quanta, quanta guerra… (1980). I first analyze the exiled subject taking into account how the novel, in the tradition of the Bildungsroman, narrates the travel story of its protagonist, Adria Guinart, from his departure from home to his return as the mythic hero in search of a truth, or as the picaresque antihero of the Quest-Romance. Concurrently, I study the construction of collective memory from the protagonist's individual memory, as he passes from infancy—when he runs away from home to go to war—to adulthood—when the war ends—where he undergoes a wide range of experiences to become a man.

In this article I suggest that Santiago Rusinol's Llibertat! explores a theatre of ideas and current affairs which resonates with Henrik Ibsen's. Through it, the conflicts and the message of Rusinol's play denounce the mediocrity and bourgeois intolerance of his society. It is not correct to frame Rusinol's theatrical aesthetics solely within symbolist theatre, as many critics do; instead, it must be seen as an appropriation of Ibsen's ideology in order to rethink how Rusinol's play has been categorized by the critics in the last few decades. The stress on ironical distancing, the individualization of the characters and the specificity of the kind of society portrayed are the characteristics that reveal the influence of the aesthetics of Ibsen's theatre of ideas. Rusinol uses irony and parody in order to show the status of Ibsen's man: from man to the universe and society, like a divided soul. Rusinol's is a social drama that fulfils the expectations people had of him that he would renew Catalan t...

In this article, the author analyzes how Salvador Espriu in La pell de brau (re)builds the myth of Sepharad that refers to the Hebrew name of the assembly of the medieval Hispanic kingdoms. La pell de brau is a work that opens the "collective cycle" toward a "we" framed within a specific historical context. The poet criticizes the unified vision of the Spanish nation and of the Catholic religion. The (re)construction of the myth of Sepharad not only reflects the crisis of the subject in search of an identity in an intolerant Spain after the civil war but also subverts the myth of the Spanish nation as created by the doctrine of National Catholicism under Franco.

We report the dispersal of Conostegia xalapensis (Melastomataceae) and Coussapoa oligocephala (Urticaceae) seeds by Underwood's long-tongued bat, a species considered to be a specialized nectar and pollen consumer. Informamos la dispersion de semillas de Conostegia xalapensis (Melastomataceae) y Coussapoa oligocephala (Urticaceae) por el murcielago de lengua larga de Underwood, una especie considerada como consumidora especializada en nectar y polen.
