EL BANQUETE PRIVADO Y EL BANQUETE COMUNAL EN EL SANTUARIO DE CANCHO ROANO

In recent fieldworks carried out at the archaeological site of Cancho Roano, a boundary pitfull-up with a big amount of animal bones and pottery have been discovered surrounding the building. The analysis of these remains allow us to infer the celebration of a communal banquet during the last moments of occupation of the complex, similar to those well-know in other sites of the Iberian Peninsula and Central Europe. In opposition, the presence of banquet tools with a more restricted use such as spits or tools related to the manoeuvring of wine inside the building, implies another kind of commensality practices with a exclusively private character.Las recientes excavaciones en el yacimiento de Cancho Roano han puesto al descubierto un foso perimetral que rodeaba el edificio y en el que se acumulaban gran cantidad de restos óseos y cerámicos. El análisis de estos restos permite deducir la celebración de un banquete comunitario durante los últimos momentos de vida del complejo, de características similares a los que se conocen en otros lugares de la Península Ibérica y de la Europa Central. En oposición, la presencia en el interior del edificio de utensilios de banquete de uso más restringido como asadores u objetos relacionados con la manipulación del vino hablan de otro tipo de prácticas de comensalidad más privada que también estarían documentadas en el yacimiento

'Background noise' and landscape exploitation in the Late Iron Age Andalusian countryside

Proceeding of the international meeting Siena, Italy, May 25-27, 2007.In this paper we present the results from a survey carried out from 2000 to 2003 in the Guadiana Menor valley (Jaen province, Spain). The sampling strategy was designed to explore the presence of archaeological finds in very different landscape units, from the floodplains to the uncultivated slopes of the Cazorla massif. Field survey revealed very high contrasts in fi nd densities, suggesting different patterns of land use. On the valley floor we recorded a weak carpet-like pattern of sherds dating from the Iron Age to Roman times. Its distribution suggests intensive agricultural activities such as manuring in a context of increasing pressure on resources during the Romanization process. In the highland area, the much more scarce evidence seems to be connected with pastoral activity, intensive farming of small valleys, and control over strategic mountain passes. We will here present methodological issues relating to the field survey and reliability problems raised by erosion and land use history of the study area.The work presented in this paper was developed in the framework of the research project ‘El Poblamiento Ibérico en el valle del Guadiana Menor. Una perspectiva desde la Arqueología del Paisaje’ (DGES-PB98/0775), led by Teresa Chapa Brunet.Peer Reviewe

Production of potential land use maps using remote sensing data for landscape archaelogy research: protohistoric societies in the Guadiana Menor River Valley (Eastern Andalusia)

Trabajo presentado al VII Congreso Ibérico de Arqueometría (CIA): S4 "Prospección geofísica y teledetección", celebrado en Madrid del 8 al 10 de octubre de 2017.[ES]: Se presenta la elaboración, a partir de imagen Landsat e información geográfica auxiliar, de un mapa digital que muestre la distribución de los usos del suelo potenciales más adecuados para economías paleotécnicas. Dicho mapa está concebido para su utilización, mediante tecnología SIG, en análisis de arqueología del paisaje dirigidos al estudio de la ubicación de asentamientos pre y protohistóricos, como el análisis de captación económica. El procedimiento de elaboración consta de dos fases: elaboración de un mapa de cubiertas actuales a partir de la imagen de satélite y conversión de dicho mapa en otro de usos potenciales mediante la utilización de la información auxiliar. Dicho trabajo se enmarca en una investigación sobre la evolución de la sociedad protohistórica en el valle del Guadiana Menor (Andalucía oriental).[EN]: This paper presents the production, using Landsat image and ancillary geographic data, of a digital map that comprises the distribution of potential land uses that are more suitable for paleotechnic economies. This map is conceived to be used, through GIS technology, in landscape archaeology analyses devoted to the study of pre and protohistoric settlement location, like site catchment analysis. Production procedure has two stages: generating a map of current coverages using satellite images and transforming it into a potential land use map by means of ancillary data. This work belongs to the framework of an ongoing research about the evolution of protohistoric societies in the Guadiana Menor valley (eastern Andalusia).Peer reviewe

Fluorescence Study of Riboflavin Interactions with Graphene Dispersed in Bioactive Tannic Acid

The potential of tannic acid (TA) as a dispersing agent for graphene (G) in aqueous solutions and its interaction with riboflavin have been studied under different experimental conditions. TA induces quenching of riboflavin fluorescence, and the effect is stronger with increasing TA concentration, due to pi-pi interactions through the aromatic rings, and hydrogen bonding interactions between the hydroxyl moieties of both compounds. The influence of TA concentration, the pH, and the G/TA weight ratio on the quenching magnitude, have been studied. At a pH of 4.1, G dispersed in TA hardly influences the riboflavin fluorescence, while at a pH of 7.1, the nanomaterial interacts with riboflavin, causing an additional quenching to that produced by TA. When TA concentration is kept constant, quenching of G on riboflavin fluorescence depends on both the G/TA weight ratio and the TA concentration. The fluorescence attenuation is stronger for dispersions with the lowest G/TA ratios, since TA is the main contributor to the quenching effect. Data obey the Stern-Volmer relationship up to TA 2.0 g L-1 and G 20 mg L-1. Results demonstrate that TA is an effective dispersant for graphene-based nanomaterials in liquid medium and a green alternative to conventional surfactants and synthetic polymers for the determination of biomolecules.Ministerio de Ciencia, Innovación y Universidade

Propuesta de parámetros y caracterización de los grupos de las redes sociales orientados a la docencia universitaria: experiencia y resultados

Social networks are currently established in the personal activity of the university students. However the use of social networks in the teaching-learning process is reserved just for a few isolated cases. It would be very interesting to include the social networks in the teaching daily activities. This article presents a measurement of social network groups focussed on university teaching. The measurement was done through different rates to provide empirical corroboration of the target group profile. The group profile is important since the group guidance could be different due to the teacher interests. The results show that through the established measurement it is possible to clearly distinguish three groups profiles. Deciding the profile which you want to apply to a group will allow defining the strategy, which will optimize the learning process using an environment closer to the students.Actualmente las redes sociales están implantadas en la actividad personal de los estudiantes universitarios. Sin embargo, el uso de las redes sociales en el proceso de enseñanza- aprendizaje está reservado a algunos experimentos aislados. Es de gran interés conseguir incluir las redes sociales en la actividad diaria de la docencia. En este artículo se presenta la medición en el uso de los grupos de las redes sociales en la enseñanza universitaria. La medición se realiza por medio de unos índices que permiten corroborar empíricamente el perfil de cada grupo. El perfil del grupo es importante, puesto que la orientación del grupo puede ser diferente en función de los intereses del docente. Los resultados obtenidos demuestran que a través de los índices presentados es posible distinguir tres perfiles de grupos bien diferenciados. Decidir el perfil que se quiere dar a un grupo permite definir la estrategia a seguir para optimizar el proceso de enseñanza-aprendizaje usando un medio cercano a los alumnos

Las fíbulas de caballito y jinete “tipo Castellares”: Un símbolo compartido por los jefes de caballería de los pueblos prerromanos de la meseta

The “horse” brooches, with or without a rider, are usually linked to an equestrian elite that assumes the leading role in the new social organization of the Later Iron Age of Celtic Hispania, structured around the oppida and their territories. Almagro-Gorbea and Torres (1999) carried out a typo-chronological classification of the known specimens, identifying a series of workshops. Compared to a catalog of 136 pieces, those that included a horseman represented only 10%. A series of new finds, as well as a fresh study of previously known specimens in various museum collections, enable the identification within this group of a specific type of horse-and-rider fibula with a distribution that includes the Celtiberian, Vaccean and Vetonian territories. Named “Castellares” type, the formal characteristics of all the specimens are identical. Their formal, technical and analytical study allows for their interpretation as shared symbols of alliances between chiefs in times of conflict.Las fíbulas “de caballito”, con o sin jinete, suelen vincularse con una élite ecuestre que asume el protagonismo en la nueva organización social de la segunda Edad del Hierro de la Hispania céltica, estructurada en torno a los oppida y sus territorios. Almagro-Gorbea y Torres (1999) realizaron una clasificación tipo-cronológica de los ejemplares conocidos, identificando una serie de talleres. Frente a un catálogo de 136 piezas, las que incorporaban un jinete representaban solo un 10 %. Una serie de nuevos hallazgos, así como las revisiones realizadas en las colecciones de diversos museos, permiten identificar dentro de este grupo un tipo concreto, con una distribución que abarca los territorios celtibérico, vacceo y vetón. Denominado como “tipo Castellares”, las características formales de todos los ejemplares son idénticas. Su estudio formal, técnico y analítico permite plantear su interpretación como símbolos compartidos de alianzas entre jefes en momentos de conflicto

The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.In conclusion, this study confirmed the association of 31 GWASidentified SNPs with CLL risk and shed some light on the function of some of these biomarkers in the modulation of TReg, B, and T cell differentiation and proliferation, blood concentrations of B cell-related proteins, cell survival, and the expression of immuneand non-immune-related loci. Though outside the scope of the current study, it is important to mention that additional functional studies using blood samples from CLL patients are still required to validate our findings and to decipher the exact biological mechanisms behind the observed associations. A potential limitation of this work was the relatively small population size of the CRuCIAL cohort that hampered the validation of the SNPs showing modest associations.European Union's Horizon 2020 research and innovation program 856620Instituto de Salud Carlos III PI17/02256 PI20/01845Consejeria de Economia, Conocimiento, Empresas y Universidad (Granada, Spain) A-CTS-448-UGR18 Consejeria de Transformacion Economica, Industria, Conocimiento y Universidades (Sevilla, Spain) PY20/01282Generalitat de CatalunyaGeneral Electric 17SGR437Gilead Sciences GLD17/00282"Xarxa de Bancs de tumors" - Pla Director d'Oncologia de Catalunya (XBTC)Fondazione AIRC per la ricerca sul cancro Fondazione Cariplo TRIDEO 16923 AIRC IG21436Spanish Association Against Cancer (AECC) Scientific Foundation grant GCTRA18022MOREConsortium for Biomedical Research in Epidemiology and Public Health (CIBERESP), action Genris

Extensive Sheep and Goat Production: The Role of Novel Technologies towards Sustainability and Animal Welfare

[EN] Sheep and goat extensive production systems are very important in the context of global food security and the use of rangelands that have no alternative agricultural use. In such systems, there are enormous challenges to address. These include, for instance, classical production issues, such as nutrition or reproduction, as well as carbon-efficient systems within the climate-change context. An adequate response to these issues is determinant to economic and environmental sustainability. The answers to such problems need to combine efficiently not only the classical production aspects, but also the increasingly important health, welfare, and environmental aspects in an integrated fashion. The purpose of the study was to review the application of technological developments, in addition to remote-sensing in tandem with other state-of-the-art techniques that could be used within the framework of extensive production systems of sheep and goats and their impact on nutrition, production, and ultimately, the welfare of these species. In addition to precision livestock farming (PLF), these include other relevant technologies, namely omics and other areas of relevance in small-ruminant extensive production: heat stress, colostrum intake, passive immunity, newborn survival, biomarkers of metabolic disease diagnosis, and parasite resistance breeding. This work shows the substantial, dynamic nature of the scientific community to contribute to solutions that make extensive production systems of sheep and goats more sustainable, efficient, and aligned with current concerns with the environment and welfareSIThe CECAV authors acknowledge financial support of the research unit, which was financed by the National Funds from FCT, the Portuguese Foundation for Science and Technology (FCT), project number UIDB/CVT/00772/2020.
