[EN] This paper describes the operation and implementation of a Data Aggregator based on an Industrial Gateway (DAIG) for the storage and transmission of information from an experimental Smart microgrid hybridised with green hydrogen. This DAIG consists of a Siemens IOT 2050, a commercial device that combines physical characteristics such as robustness and open-source software. To achieve this objective, each subsystem involved in the microgrid has a set of sensors and a Data Acquisition Device (DAD) to obtain the relevant logical magnitudes of its operation. The IOT 2050 serves as a centralised system, communicating via Modbus TCP/IP with each DAD and storing the data read in a local database by means of a Python script. Finally, as an example of the application of the designed infrastructure, an IoT software is implemented to visualise the data stored in the DAIG.

Beckett's ‘Long after Chamfort’, eight late poems, is arguably the only work in Beckett’s oeuvre that has been published as a structurally bilingual text. This paper attempts to put the verse renderings in English of Chamfort’s French prose maxims to use by asking three general – and perhaps also slightly obnoxious – questions. Beckett’s doggerel translations of the 18th-century maxims by Chamfort have been commented on in several other productive ways. Here, the three questions are related to the topic of bilingualism and translation – even if the conclusions relate to wider issues in criticism. Is there a bilingual text in Beckett’s work; what is translation ideally for Beckett; and what does the structurally bilingual text ‘Long after Chamfort’ – and Beckett’s work generally, perhaps – do to some of the ideas that it uses? The results of the analysis prompt us to grasp facets of Beckett's work that some of the tenets of current criticism have tended to erase.

For the Dutch Cultural Heritage Agency (RCE), the state of knowledge on medieval village formation in the Netherlands was investigated based on the output of a decade of ‘Malta-archaeology’. The project made clear that the huge amount of development-led archaeological research has brought only limited progress on this particular theme, because of the scale of the excavations, the focus of the observations and a general lack of research frameworks at village level and regional frameworks specifically addressing village formation from which targeted research questions can be derived. In addition, very little research has been undertaken within presently inhabited villages, resulting in a major bias in the dataset towards deserted medieval settlements. To increase our understanding on village formation and the development of villages, archaeological research needs to be conducted within municipal research agendas based on an historical-geographical framework which provide specific hypotheses and questions to test and explore. Moreover, syntheses would greatly benefit from a continuity of knowledge in the region and complementary (academic) observations within existing historical villages.

La hemorragia digestiva de origen oscuro constituye el 5-10% del total de hemorragias digestivas, siendo el intestino delgado la localización más frecuente. Por su sencillez y fiabilidad la enteroscopia con cápsula es la técnica de elección tras un primer estudio endoscópico negativo (gastroscopia e ileo-colonoscopia). Sin embargo, en ocasiones, el origen del sangrado no se identifica en el interior de éste, sino fuera y al alcance de la endoscopia convencional (esófago, estómago o colon). Presentamos el caso de un paciente de 46 años con anemia ferropénica y varios estudios endoscópicos previos negativos a quien se detectó un tumor gástrico (GIST) durante una enteroscopia con cápsula. El diagnóstico definitivo se obtuvo tras el estudio histológico de la pieza quirúrgica. Obscure gastrointestinal bleeding accounts for approximately 5-10% of patients presenting with gastrointestinal haemorrhage. The majority of lesions responsible were found to be located in the small bowel. Currently, capsule endoscopy is the first-line tool to investigate the small bowel as it is a non-invasive, feasible and simple procedure. However, capsule endoscopy sometimes identifies the source of bleeding outside the small bowel and within the reach of conventional endoscopy. We present the case of a 46 year-old man with few prior negative endoscopic procedures and iron-deficiency anaemia due to gastric GIST.

Most of the toxicity assays were developed for the evaluation of conventional drug compounds in vitro. In fact, researchers have realized that not all cytotoxic and genotoxic assays are appropriate for the evaluation of nanoparticle toxicity as several nanoparticles are capable to interfere with these methods. For instance, the binding and possible inactivation of assay components involved and/or the interference with colorimetric detection are examples of nanoparticle interference on the cytotoxic assays. For a correct assessment of the toxicity of the nanoparticles under evaluation, possible nanoparticle-assay interactions need to be identified. In the present work was evaluated the possible interferences between 3 nanomaterials (TiO2 nanoparticles, nanokaolin clay and TiO2 nanoparticles immobilized in nanokaolin substrates) and the cytotoxicity (MTT, neutral red uptake (NRU), alamar blue (AB) and LDH) and genotoxicity (alkaline comet assay) assays under evaluation.

En los últimos años el interés en los recubrimientos obtenidos por sol-gel ha aumentado mucho en aplicaciones de protección y refuerzo de superficies contra la corrosión. Asimismo, el uso de polimorfos de carbono (nanofibras de carbono, grafeno, grafito...) para mejorar las propiedades mecánicas y conferirle propiedades conductoras a algunos materiales, también se ha desarrollado mucho en los últimos años. En trabajos previos se prepararon y estudiaron recubrimientos híbridos de sílice-CB obtenidos por el método sol-gel. Mediante el estudio de la microestructura y composición de estos recubrimientos (SEM, Raman, ATD-TG, y FT-IR) y de las propiedades eléctricas se obtuvo que en función la temperatura de sinterización de los recubrimientos, se podía controlar la respuesta eléctrica de los composites. Esto permite abrir enormemente el campo de aplicaciones, ya que para temperaturas de sinterización por debajo de 400ºC se consiguen resistividades del orden de 10-4Ωm, apropiadas para aplicaciones en dispositivos electrónicos, electrodos, apantallamiento de interferencias electromagnéticas y radiofreciencia, etc; mientras que para temperaturas de sinterización por encima de 400ºC, obtenemos recubrimientos más resistivos que pueden aplicarse como dispositivos calefactores, anticongelantes. Por tanto, el objetivo de este trabajo es desarrollar más profundamente estas aplicaciones, así como diseñar experimentos que demuestren las múltiples posibilidades que estos recubrimientos conductores obtenidos por sol-gel pueden aportar.

En este trabajo se pretende encontrar un sistema para la determinación instrumental del grado de blanco de los peinados de lana sin blanqueadores ópticos, que permita establecer una clasificación similar a la efectuada por el examen visual del peinado por los expertos. Para ello se ha tomado como base la clasificación visual efectuada por 54 expertos de catorce peinados de lana y se han analizado sus características colorimétricas con siete aparatos y a través de ocho fórmulas que definen diferentes maneras de expresar el grado de blanco. Del análisis de los resultados obtenidos, se han elegido los tipos de aparatos y las fórmulas con los que se obtiene una clasificación análoga a la efectuada por los expertos.
