    En el trabajo que se presenta a continuación se dan a conocer los resultados aportados por la intervención arqueológica realizada sobre tres tumbas visigodas localizadas en la ciudad de Córdoba (Calle Pintor Palomino, número 55) en el año 2006, y del estudio antropológico de laboratorio realizado sobre los individuos contenidos en su interior. La importancia de estos hallazgos radica en su adscripción a una cronología precisa gracias a la localización de un triente áureo junto a una de las inhumaciones, que puede fecharse con escaso margen de error entre los años 698-702 d.C.In the work presented below are disclosed those provided by the archaeological excavation carried out on three Visigoth tombs located in the city of Córdoba (Calle Pintor Palomino, No. 55) in 2006, and the anthropological study of laboratory results performed on individuals contained therein. The importance of this site lies in its adherence to a precise chronology thanks to the location of a golden tremissis find in one of the burials, which can be dated with little margin for error between 698-702 A.D

    El Análisis de Sensibilidad (AS) es fundamental para dar robustez y credibilidad a cualquier modelo. En este trabajo se presenta una propuesta de AS espacial utilizando las herramientas disponibles en un Sistema de Información Geográfica (SIG) y aplicado en la simulación del crecimiento urbano futuro (residencial, comercial e industrial) en la Comunidad de Madrid (España), basado en técnicas de Evaluación Multicriterio (EMC) y el método One Factor at a Time (OAT). Dicho trabajo es implementado mediante la variación en un ± 25% del valor de aptitud, a nivel de píxel, de los 16 factores y pesos utilizados en el modelo. Para verificar su robustez se aplicaron tres técnicas, las cuales arrojaron los factores más influyentes y las parcelas más estables y robustas, sobre las que se podría actuar, realizando, eso sí, un análisis detallado de las mismas para planificar adecuadamente unas zonas que parecen estar abocadas a ser urbanizadas.The Sensitivity Analysis (SA) is fundamental to give robustness and credibility in any model. In this paper is presented a proposal of spatial SA using the tools available in a Geographic Information System (GIS) and applied in the simulation of the future urban growth (residential, commercial and industrial) in the community of Madrid (Spain), based on Multi-Criteria Evaluation (MCE) techniques and the One Factor at a Time (OAT) method. This research is implemented through the variation in a ± 25% of the aptitude value, at pixel level, to the 16 factors and weight used in the model. To verify its robustness, were applied three techniques, which threw the most influents factors and the more stables and robust plots, on which it could act, performing, a detailed analysis thereof for planning adequately some zones that seems doomed to be urbanized.Ministerio de Educación y Cienci

    Most current multiplayer 3D games can only be played on dedicated platforms, requiring specifically designed content and communication over a predefined network. To overcome these limitations, the OLGA (On-Line GAming) consortium has devised a framework to develop distributive, multiplayer 3D games. Scalability at the level of content, platforms and networks is exploited to achieve the best trade-offs between complexity and quality

    Objective: The objective of the present study was to determine the dietary patterns of a Mediterranean cohort and relate them to the observed patterns of beverage consumption. Design: Prospective cohort study. Dietary habits were assessed with a semiquantitative FFQ validated in Spain. A principal components factor analysis was used to identify dietary patterns and to classify subjects according to their adherence to these patterns. The association between adherence to each dietary pattern and beverage consumption was assessed cross-sectionally. In a longitudinal analysis (2-year follow-up), the relationship between adherence to the baseline dietary patterns and the likelihood of changing alcohol consumption was ascertained. Setting: The SUN (Seguimiento Universidad de Navarra) study is conducted in Spain. Subjects: In total, 15 073 university graduates were included in the analyses. Results: Two major dietary patterns were identified. We labelled them as ‘Western dietary pattern’ (WDP) and ‘Mediterranean dietary pattern’ (MDP). Higher adherence to the WDP was associated with higher consumption of carbonated beverages and whole-fat milk (P for trend ,0?001), while higher adherence to the MDP was associated with higher consumption of decaffeinated coffee, orange juice, other natural juices, diet carbonated drinks, low-fat milk and bottled water (P for trend ,0?001). Participants with higher adherence to the WDP were less likely to decrease their alcohol consumption during follow-up (OR between extreme quintiles50?68; 95% CI 0?56, 0?84). By contrast, participants with higher adherence to the MDP were less likely to increase their alcohol consumption (OR50?66, 95% CI 0?46, 0?95). Conclusion: In this cohort of university graduates, a healthier dietary pattern was associated with a healthier pattern of beverage consumption

    14 pags., 10 figs.With the objective of contributing to the European development of materials, technologies and facilities for the demonstration of the thermonuclear fusion, the construction of the unique TechnoFusión facility was planned in 2009. The TechnoFusión consortium, formed by selected Spanish research groups and laboratories located in Madrid, has jointly advanced in the search for solutions to the remaining technological issues of nuclear fusion by magnetic and inertial confinement. In addition, the foundation of the TechnoFusión partnership has been essential to create a network of collaborations, and also to expand and specialize human resources, by training scientists and technical staff in the use of high-tech tools. Supported by the TechnoFusión_Comunidad Madrid (III) regional programme, the consortium is focused on providing support for the construction of medium-­sized, relevant facilities in Madrid (Spain). Regarding magnetic and inertial fusion issues, the programme is structured in several key experiments and infrastructures, which combine the development of materials, of cutting-edge technologies and the construction of associated facilities, with the progress in simulation and application of computational neutronics:The authors acknowledge the funding by Community of Madrid, co-financed with Structural Funds (ERDF and ESF)), through the TechnoFusión (III)-CM (S2018/EMT-4437) programme.

    La sustitución C>A en el NT 46 en la región 3’ UTR (Alfa Complex Protected Region) del gen ALFA 1 de globina ¿mutación o polimorfismo?

    Get PDF
    PC-048 Antecedentes: Las regiones no traducidas [UnTranslated Region (UTR)] desempeñan un papel crucial en la regulación postranscripcional de la expresión génica, incluida la modulación del transporte de ARNm fuera del núcleo, la eficacia de la traducción, la localización subcelular y la estabilidad. La estabilidad del ARNm es un factor decisivo para el desarrollo y funcionamiento normal de los glóbulos rojos. En el caso del ARNm de a-globina, los principales determinantes de la estabilidad se localizan en el extremo 3’ UTR; en concreto, se han identificado 3 áreas discontinuas ricas en citosina (C) ubicadas entre los nucleótidos (nt) 25 y 70 corriente abajo del codon de parada. Estas áreas ricas en C son responsables de atraer a una ribonucleoproteína (RNP) llamada a-globina poli (C) de unión o a-complejo proteína (aCP) para estabilizar la molécula de ARNm. Wagoner et al. demostraron a través del análisis in vitro que cualquier mutación en estos elementos ricos en C dificulta la unión del ARNm de a-globina con el aCP y desestabiliza al ARNm. Objetivos: Presentamos 15 pacientes con la sustitución C>A en el extremo 3’UTR del gen a1 de globina, localizada en la región del complejo a (aCP), la cual podría causar a-talasemia no deleción al afectar a la estabilidad postranscripcional (estabilidad del ARNm) o tratarse de un polimorfismo. Métodos: Se han estudiado 15 pacientes pertenecientes a 12 familias, todas de origen español excepto dos, una procedente de Rumanía y otra de Marruecos. Las edades estuvieron comprendidas entre 2 y 67 años. Todos fueron estudiados por presentar microcitosis e hipocromía sin ..

    OBJECTIVE To investigate the association of the dietary pattern with the presence of newly diagnosed glucose tolerance abnormalities among Chinese adults. RESEARCH DESIGN AND METHODS A total of 20,210 adults aged 45–69 years from the 2002 China National Nutrition and Health Survey were included. Information on dietary intake was collected using a validated food frequency questionnaire. Factor analysis and cluster analysis were used to identify the food factors and dietary pattern clusters. RESULTS Four dietary pattern clusters were identified (“Green Water,” “Yellow Earth,” “Western Adopter,” and “New Affluence”). The prevalence of glucose tolerance abnormalities ranged from 3.9% in the Green Water to 8.0% in the New Affluence. After adjustment for area, age, sex, current smoking, and physical activity, subjects in the Yellow Earth cluster (prevalence ratio 1.22 [95% CI 1.04–1.43]) and New Affluence cluster (2.05 [1.76–2.37]) had significantly higher prevalence rates compared with those for the Green Water cluster. After further adjustment for BMI and waist-to-height ratio, the elevated risk in the New Affluence remained statistically significant. CONCLUSIONS Dietary patterns and food factors are associated with the presence of glucose tolerance abnormalities in China, even independent of obesity. A New Affluence diet is an important modifiable risk factor, which needs attention from the prevention point of vie

    Revision of Training Models on Ultrasound-Guided Vascular Access: Presentation of an Animal Model

    Simulation has been defined as the representation of something as real. It is necessary for performing the ultrasound-guided vascular cannulation technique correctly. The use of training models for diagnostic or therapeutic procedures: improves the quality of care for patients; decreases stress level that it can produce the realization of a new technique directly on the patient and; can be used as many times as the model is reproduced, also serving as a method for the resolution of some problems that may appear related to the in vivo technique. The evidence shows that simulation plays an important role in the acquisition of skills to perform invasive procedures. The use of ultrasound in vascular accesses whether peripheral or central, arterial, or venous, improves the success rate in the canalization and reduce the complications derived from the technique in certain critical situations (coagulopathy, thrombocytopenia, obesity, etc.) specially in pediatric patients given the variability of depth and diameter of its vessels with respect to the adult population. To facilitate learning in the technique of echoguided puncture, a training model is presented that is easily reproducible, economical and with a high fidelity in relation to the punctures performed on the patient

    The objective of fisheries management is the sustainable exploitation of the fish resources over the extent of their spatial distribution. Along with the Common Fisheries Policy (CFP) objectives, the socio-economic viability of the fisheries exploiting the resource is also to be achieved. To reach these aims, managers need to define the management units they are going to work with. For the purpose of GEPETO project, we define a management unit (MU) as the set of fishing fleets exploiting a common pool of fish resources with strong spatial overlapping and sharing of habitats, which make them being typically fished together. In other words, a MU is the set of fishing fleets exploiting a common fish community over their spatial distribution. MUs have to be defined by the fish community, by the spatial range of distribution of the fish community, and by the set of fishing fleets sharing the exploitation of the fish communityL'objectif de gestion de la pêche est l'exploitation durable des ressources halieutiques sur l'étendue de leur répartition spatiale. Avec la nouvelle Politique Commune de la pêche (PCP) l' objectif de la viabilité socio-économique des pêcheries exploitant la ressource doit également être réalisé. Pour l'atteindre, les gestionnaires doivent définir des unités de gestion. Les partenaires du projet GEPETO, définissent une unité de gestion (MU) comme l'ensemble des flottes de pêche exploitant un pool commun de ressources halieutiques disponibles dans des habitats communs, ce qui les rend très imbriquées. En d'autres termes, un MU est l'ensemble des flottes de pêche exploitant une communauté de poissons ordinaires sur leur répartition spatiale. La MU peu être définie par la communauté de poissons, par la gamme spatiale de la distribution de la communauté de poissons, et par l'ensemble des flottes de pêche qui partagent l'exploitation de la communauté de poissons
