Ritual, violencia y enfermedad: Los enterramientos en "decúbito prono" de la necrópolis fundacional de Valentia

La necrópolis romana de la calle Quart de Valencia es un amplio cementerio datado entre el s. IIa. C. y el IV d. C., localizado en el centro histórico de la ciudad. En total a lo largo de las cinco campañas de excavación, se han recuperado 180 inhumaciones y 64 cremaciones. Entre las primeras, se documentaron una serie de enterramientos excepcionales, de los que destacan 11 esqueletos enterrados en posición de decúbito prono. En este trabajo presentamos su estudio arqueológico, bioantropológico y paleopatológico. Los estudios de laboratorio han puesto de manifiesto que la mayoría de los esqueletos son varones, de complexión robusta y con abundantes marcadores de actividad muscular repetida. Los hallazgos paleopatológicos han demostrado una estrecha relación entre la posición del cuerpo y la presencia de lesiones traumáticas acontecidas durante el perimortem, así como posibles patologías infectocontagiosas como tuberculosis y lepra

Memory written in bones : From Funus rites to the osteobiography of Valentia

The Roman necropolis in Carrer Quart in Valencia (Spain) is the city?s oldest known cemetery, dating from between the second century BC and third century AD. Based on its archaeological and bioanthropological analysis, we examine various hitherto unknown issues from an interdisciplinary perspective. By using isotopic archaeochemistry, various aspects, such as those concerning funerary practices, social stratification, paleodemography, quality of life, and the impact of disease, food, and the subsistence economy, as well as population mobility, have enriched our knowledge of the landscape of the old town. Science and memory converge in Valentia through the culture and traditions documented in the funerary ritual (funus valentiae)

Developing Project Managers’ Transversal Competences Using Building Information Modeling

The emergence of building information modeling (BIM) methodology requires the training of professionals with both specific and transversal skills. In this paper, a project-based learning experience carried out in the context of a project management course at the University of Extremadura is analyzed. To that end, a questionnaire was designed and given to students who participated in the initiative. Results suggest that BIM can be considered a virtual learning environment, from which students value the competences developed. The emotional performance observed was quite flat. Similarly, students valued the usefulness of the initiative. Students expressed a desire for the methodological change of the university classes, and thought that BIM methodology could be useful for other courses. The results obtained show a line of work to be done to improve the training of students and university teaching

Estructuras de hormigón pretensado armadas con FRP

El objetivo del presente Proyecto Final de Carrera (PFC) es la actualización del estado de la cuestión en el campo del uso de hormigón pretensado con barras de refuerzo formadas por materiales compuestos a base de fibras de carbono, aramidas o vidrio y una matriz formada por resinas poliméricas a base de poliéster, vinyil éster o epoxi, conocidas como barras FRP (Fiber Reinforced Polymer), designándose CFRP, AFRP y GFRP, según sean de carbono, aramidas o vidrio respectivamente. La consecución de dicho objetivo general se ha logrado mediante la realización de los siguientes objetivos específicos: búsqueda y análisis de la bibliografía correspondiente al campo de estudio de las barras poliméricas FRP en el uso del hormigón pretensado (que se plasma en la recopilación de una base de datos bibliográfica), inventario de los principales grupos de investigación, exposición de la normativa internacional relativa al objeto del estudio, y por último, una recapitulación final en que se resumen las conclusiones de la investigación realizada y se hace una relación de las principales aplicaciones de los FRP en hormigón pretensado.García Polo, JM.

Erosion caused by propeller jets in a low energy harbour basin

This is an Accepted Manuscript of an article published by Taylor & Francis Group in Journal of Hydraulic Research on January, 2017, available online at: http://www.tandfonline.com/10.1080/00221686.2016.1252801Field data of a harbour basin are compared with analytical formulations for predicting maximum scouring depth due to propeller jets. Spatial data analysis of seven-year biannual bathymetries quantifies the evolution of the scouring hole along with the sedimentation process within a harbour basin. The maximum scouring depth is found to be of the order of the propeller diameter with a maximum scouring rate within the first six months of docking manoeuvring. Three of the analysed expressions yielded realistic results while observed discrepancies between the theoretical predictions and field data are related to scaling factors. The outcomes of this analysis can be extrapolated to other harbours to improve their management. The obtained results highlight the importance of field data in developing combined physical and numerical models.Peer ReviewedPostprint (author's final draft

Synthesis and Use of Silica Xerogels Doped with Iron as a Photocatalyst to Pharmaceuticals Degradation in Water

The main objective of this study was to assess the photoactive properties of iron-doped silica xerogels under solar radiation. For this purpose, silica xerogels (XGS) synthesized by the sol-gel method were doped with Fe (III) by two routes: impregnation and polymerization. XGS samples were texturally and chemically characterized by N2 adsorption, XRD, FTIR, Raman, SEM-EDX, DRS, and PL, evidencing the suitability of using XGS substrates to host iron clusters on their surface with total compatibility. Chlorphenamine (CPM), ciprofloxacin (CIP), and ranitidine (RNT) were used as model compounds. The degradation of the molecules was made under simulated solar radiation testing the synthesis pad, load, material size, and reuse. It was found that XGS doped with Fe by the impregnation route (XGS-Fe-Im) were able to completely degrade CPM and RNT in 30 min and 10 min, respectively, whilst for CIP it achieved the removal of 60% after 1 h of solar radiation exposure, outperforming parent materials and solar radiation by itself. The study of the degradation mechanism elucidated a major influence from the action of HO radicals. The present investigation offers a potential route of application of XGS Fe-doped materials for the removal of emerging concern contaminants under near real-world conditions.Junta de AndaluciaEuropean CommissionSpanish Government P18-RT-4193Consejo Nacional de Ciencia y Tecnologia (CONACyT) CVU 4921

Rituales alimentarios y economía de subsistencia en las tumbas de cámara de la necrópolis romana de la Calle Quart de Valentia (SS. II A. C. - III D. C.)

The osteoarchaeological collection from the roman period at Quart street of Valencia comprises 181 inhumations from the Republican to the Roman Empire period (2nd BC to III AD). This is the oldest cemetery excavated in the city where a very significant sample of the foundational population from the 138 BC was found. In this work, the results from the funerary analysis, the bio-anthropological, palepathological and the paleodiet are discussed. The individuals came from a group of burials found at some hypogea belonging to the oldest part of the necropolis which coincided with the foundation of the city on the last third of the 2nd century B

Localización neuroeléctrica de procesos cognitivos

Recording techniques of electrical cerebral activity with surface electrodes are shown and supported as a valid choice of a physiological study of the cognitive function of the human brain. Likewise, we describe the techniques of topographical representation of neuroelectrical potentials, as well as the current source density analysis and the localization of cerebral generators by evoked potentials. We conclude that it is possible to determine the localization of active cortical zones during perception, motor and cognitive processes, starting from a limited number of physiological hypotheses, in relation to the electrical behaviour of the cortical neurons and according to an electrical model of the head.Se presentan y defienden las técnicas de registro de la actividad eléctrica cerebral con electrodos de superficie como una alternativa válida para el estudio fisiológico de la función cognitiva del cerebro humano. Asimismo, se describen las técnicas de representación topográfica de potencial neuroeléctrico, así como las de análisis de densidad de corriente y de localización de generadores cerebrales de potenciales evocados. Se concluye que es posible determinar la localización de zonas corticales activas durante procesos de percepción, motores y cognitivos, partiendo de un número limitado de hipótesis fisiológicas, en relación al comportamiento eléctrico de las neuronas corticales y según un modelo eléctrico de la cabeza.DGICYT TM90-15
