Innovation in the Public Library: where we are and where we go

La innovación, elemento fundamental en el momento histórico actual, resulta primoridal para que instituciones de todo tipo afronten con garantías los retos que se les plantean. Generalmente, estos procesos de innovación se basan fundamentalmente en el componente tecnológico, aunque también es posible llegar a innovar con otros recursos, planteamientos, y enfoques de servicio. La innovación también se está convirtiendo en una de las señas de identidad de las bibliotecas públicas españolas. Estas instituciones innovan principalmente a partir de la tecnología disponible ofreciendo servicios personalizados y adaptados en función de las necesidades e intereses de su comunidad de usuarios. Se analizan algunos casos paradigmáticos de servicios innovadores en bibliotecas públicas españolas.Innovation, a key element in the current historical moment, it primoridal for all institutions face up to the challenges guarantees they face.

Extraordinary absorption of decorated undoped graphene

We theoretically study absorption by an undoped graphene layer decorated with arrays of small particles. We discuss periodic and random arrays within a common formalism, which predicts a maximum absorption of $50\%$ for suspended graphene in both cases. The limits of weak and strong scatterers are investigated and an unusual dependence on particle-graphene separation is found and explained in terms of the effective number of contributing evanescent diffraction orders of the array. Our results can be important to boost absorption by single layer graphene due to its simple setup with potential applications to light harvesting and photodetection based on energy (F\"orster) rather than charge transfer.Comment: 5 pages, 3 figure

Prismas trasescalares en el estudio de las migraciones

This article aims to reflect on the way social anthropology can contribute to the study of migrations and, simultaneously, to “find out” what the discipline can also learn from this field of study, and thus to transfer its knowledge to other areas. From here we will learn how important here and there are for the study of migrations, not as situations or places, but as constructed and reconstructed notions of identification processes. From that point, we will try to show some examples of our ethnographic research that lead to the analysis of the concept of situation from its relational dimension. A notion of context that shouldn’t be seen in relation to space, but in the provision of meanings for the social and cultural events within it. Therefore a trans-scalar approach of anthropology will arise in a global context and referring to any sociocultural pnenomenon. Such an approach wil lead to the enforcement of a multisited ethnography.El presente artículo pretende reflexionar sobre lo que la antropología social puede aportar al estudio de las migraciones y, a la vez, “descubrir” lo que puede aprender también la disciplina de este campo de estudio, y, de esta manera transdisciplinar, sus saberes. De aquí aprenderemos lo importante que es para el estudio de las migraciones el aquí y allí no como situaciones o lugares, sino como nociones que construyen y reconstruyen los procesos de identificación. Desde ellos trataremos de mostrar varios ejemplos de nuestras investigaciones etnográficas, que nos pongan en la situación de analizar el concepto de contexto desde sus dimensiones relacionales. Es una noción de contexto que no debe dimensionarse en lo espacial, sino en la dotación de significados de los acontecimientos sociales y culturales que deben ser inscritos en él. De todo ello surgirá el enfoque transescalar, que en un contexto global debe tomar la antropología en el estudio de cualquier fenómeno sociocultural, lo que le obligará a intensificar una etnografía multisituada

Manipulating chemistry through nanoparticle morphology

We demonstrate that the protonation chemistry of molecules adsorbed at nanometer distances from the surface of anisotropic gold nanoparticles can be manipulated through the effect of surface morphology on the local proton density of an organic coating. Direct evidence of this remarkable effect was obtained by monitoring surface-enhanced Raman scattering (SERS) from mercaptobenzoic acid and 4-aminobenzenethiol molecules adsorbed on gold nanostars. By smoothing the initially sharp nanostar tips through a mild thermal treatment, changes were induced on protonation of the molecules, which can be observed through changes in the measured SERS spectra. These results shed light on the local chemical environment near anisotropic colloidal nanoparticles and open an alternative avenue to actively control chemistry through surface morphology.LL and LML-M acknowledge funding from European Commission Grant (EUSMI 731019).

Síndrome compartimental en joven con alteración hemática

El síndrome compartimental es una patología bien conocida que se produce por un aumento de la presión dentro de un compartimiento miofascial. Presentamos el caso de un paciente con trombopenia que sufrió un traumatismo banal. Necesitó fasciotomía del compartimiento anteroexterno de la pierna y, más tarde, esplenectomía. El diagnóstico y tratamiento tardíos de esta complicación, así como una descomprensión inadecuada, pueden conducir a la pérdida de función en una extremidad.The compartment syndrome is a well described cli- nical entity that results from increased pressure within a myo- fascial compartment. An unusual case of a patient with thrombopenia and a minimal traumatism, is reported. He required fasciotomy of the anterolateral compartment of the leg and, later, splenectomy. Late recognition and treatment of this complication, as well as inadequate decompression, can lead to loss of limb

Sofosbuvir improves HCV-induced insulin resistance by blocking IRS1 degradation

In the present study, we have demonstrated that sofos buvir (SOF) treatment improves systemic insulin resis tance in hepatitis C virus (HCV)-patients, and, for the first time, revealed which molecular mechanisms are involved in SOF effects on the impaired insulin response induced by HCV in hepatocytes
