The goal of this project was to enhance the scientific literacy of primary school and Education degree students by Pharmacy learners, using a collaborative work framework and a SERVICE-LEARNING approach, for all of them to accomplish the general and specific learning outcomes related to the subjects involved in this proposal, that is, Biology and General Chemistry from the Degree in Pharmacy and Research and Innovation in Experimental Sciences from the Degree in Education. Assessments of primary school students´ learning outcomes revealed that 93 % of the kids were able to increase their knowledge on human cells and also widened their scientific vocabulary in, at least, three to five technical words. Education students valued extremely positive the fact that they could work with a different profile of students and the feedback they received from them. Pharmacy students became aware of the importance of the teacher role in society and highlighted the difficulty they had to face when they tried to explain chemical and biological concepts to a non-scientific audience and especially to kids

Sustainability in the global wine industry: Concepts and cases

  • Gilinsky, Armand
  • Newton, Sandra K.
  • Fuentes Fernández, Rosana
We relate sustainability to the wine industry and recognize that for practitioners in the wine industry, priority number one is leaving the land in better shape for the next generation. We show an overview of sustainable wine business practices around the world and five illustrative decision-focused case studies about sustainable wineries. Among those case studies, one presented "live" at the conference: the winemaker and Director of Marketing and Communications for one of the wineries, Puerta del Viento (Spain), described their experiences in starting a sustainable wine venture in the Bierzo region.

Social risk map. The design of a complementary methodology to vulnerability indexes applied to urban regeneration activity, 24TH ISUF INTERNATIONAL CONFERENCE: CITY AND TERRITORY IN THE GLOBALIZATION AGE

  • Ruiz-Varona, Ana
  • León Casero, Jorge
Conception of urban intervention in the city is increasingly mutating from a physical urban renewal to an integrated urban approach. That is to say, measures concerning physical urban renewal should be combined with measures promoting education, economic development, social inclusion and environmental protection (European Commission, 2014). Current methodologies applied to the analysis of potential distressed areas are based on quantitative variables. The combination of these variables into a matrix characterizes the areas of the city that are subjected to different grades of intervention in terms of urban vulnerability and social exclusion. However, literature demonstrates that there are still few tools capable of measuring spatially which areas are the most sensitive to the decline in social relations within the city. Research on social maps suggests that potential attractors and risk areas can be identified from the design of a methodology based on the social perception of the public space. The application of this methodology to different case studies at the neighborhood level shows the correlation between urban vulnerability approach (quantitative) and social perception (qualitative). Indeed, perception and characterization of social risk areas empowers current urban vulnerability indicators for the integrated urban approach. Findings validate the utility of this methodology for the implementation of this model to cities and illustrate the social sphere of analysis as a platform from which to assess risk in urbanized areas.

Average TWA activity has been shown to be an independent predictor of sudden cardiac death (SCD) in chronic hean failure (CHF) patients% flowerer the influence o f cireadian rhythms on TWA remains understudied. In this work, we assessed circadian TWA changes in a CHF population and evaluated whether the prognostic value of TWA indices Ls sensitive to the circadian pattern. Hotter ECG recordings from 626 consecutive CHF patients (52 SCD) were analyzed. The index of average altemans (IAA), quantiffing the average TWA level, was measured in 4 consecutive 6-hour intervals using a multi lead fully-cuttomated method. Survival analysis vvas performed considering SCD as an independent endpoint. IAA changed along the day,. with statistically significtmt lower values during the night than during daytime. This patterrt is similar to the one observed in the mean heart rate (HR). However, a low correlation (r= 18) was found between MA and HR in windows of 128 heats. After dichototnizatthn f patients based on the third quartile of IAA indices, IAA indices computed between hours 06-12 (IAA,) and 18-24 (1AA,) successfully predicted SCD (Hazard Ratio, HaR.-2.34( 1.33-4.13) per IN, and HaR:1.87(1.04-3.36) per ktV, respectively). In conclusion, circadian variation should be considered for SCD risk prediction.

The Role of Purkinje Automaticity as an Arrhythmia Mechanism in Hyperkalaemia

  • Monasterio, Violeta

  • Pueyo, Esther
  • Rodríguez, José F.
Colección: Computing in Cardiology Conference, The pacemaker activity of Purkinje (PK) cells is usually suppressed by the sino-atrial (SA) node. Under abnormal conditions, PK cells may produce ectopic focal activity leading to tachycardia and fibrillation. This computational modelling work illustrates the potential role of PK automaticity as an arrhythmia mechanism in hyperkalaemia. First, we investigated the automaticity of isolated PK cells under hyperkalaemic conditions. Second, the potential consequences of altered PK automaticity were explored in a 1-D model of a terminal PK fibre running through a hyperkalaemic zone. Hyperkalaemia was found to accelerate the autorhythmic period of isolated PK cells with respect to control. For extracellular potassium levels >= 7.2 mM, spontaneous action potentials (APs) appeared in the PK fibre, leading to conduction disturbances and complex combinations of spontaneous and stimulation-driven APs.

Optimization of logic programs with dynamic scheduling

  • Puebla Sánchez, Alvaro Germán
  • García de la Banda, M.
  • Marriott, K.
  • Stuckey, P.J.
Dynamic scheduling increases the expressive power of logic programming languages, but also introduces some overhead. In this paper we present two classes of program transformations designed to reduce this additional overhead, while preserving the operational semantics of the original programs, modulo ordering of literals woken at the same time. The first class of transformations simplifies the delay conditions while the second class moves delayed literals later in the rule body. Application of the program transformations can be automated using information provided by compile-time analysis. We provide experimental results obtained from an implementation of the proposed techniques using the CIAO prototype compiler. Our results show that the techniques can lead to substantial performance improvement.

Issues in implementing ACE: A stack copying based and-or parallel system

  • Pontelli, Enrico
  • Gupta, Gopal
  • Hermenegildo, Manuel V.
We discuss several issues involved in the implementation of ACE, a model capable of exploiting both And-parallelism and Or-parallelism in Prolog in a unified framework. The Orparallel model that ACE employs is based on the idea of stack-copying developed for Muse, while the model of independent And-parallelism is based on the distributed stack approach of &-Prolog. We discuss the organization of the workers, a number of sharing assumtions, techniques for work load detection, and issues relaed to which parts need to be copied when a flexible and-scheduling strategy is used.

Láminas plegadas de hormigón armado. Realizaciones en España

  • García García, Rafael
Las estructuras de hormigón conformadas mediante láminas plegadas, constituyeron una variante de las láminas o cáscaras en general que llegó a formar un cierto campo o apartado propio dentro de las anteriores. El ingeniero americano Kimberly (Waggle) Kramer se refirió a ellas como un auténtico movimiento surgido en un breve plazo de tiempo hacia finales de los 50, desarrollado en pocos años y prácticamente extinguido a comienzos de los 70. Efectivamente sus más interesantes realizaciones caen dentro de este estrecho periodo. No obstante, y pese a la conciencia de su importancia, muy pocos son los estudios o trabajos realizados hasta ahora sobre las estructuras y edificaciones notables realizadas mediante láminas plegadas. En esta ponencia concreta se propone abordar el caso español y analizar y comparar los ejemplos existentes más importantes en que se empleó este tipo de estructuras. Aunque no es fácil saber el número total de las realizadas en España, puede suponerse a partir de las que se tiene constancia por su publicación que no fueron en absoluto numerosas. Las más destacables constituyen un pequeño conjunto que en general ha pasado desapercibido y cuyo estudio comparado se propone en esta ponencia. Aparte de su singularidad dentro del panorama español de aquellos años, sería destacable también su variación, ya que casi cada una plantea un caso particular y una cierta tipología acorde con el problema planteado. En cuanto a sus autores, y aunque es cierto que no realizó ninguna de estas estructuras en nuestro país, es ineludible tomar como referencia las experiencias y recomendaciones pioneras de Candela, si bien en España tenemos también interesantes ejemplos de Eduardo y José Antonio Torroja y de arquitectos como Fisac, Vaquero Palacios o José Ramón Azpiazu. De este último en colaboración con Pedro Pinto y los ingenieros José Antonio Torroja, Florencio del Pozo y Rafael López Blanco sería precisamente la que es probablemente la más notable de las erigidas en nuestro país, la cubierta del canódromo madrileño erigida a comienzos de los años 60 y cuya singularidad dio motivo a interesantes estudios y ensayos según los más modernos métodos de la época. Este estudio se enmarca dentro de una investigación más amplia realizada por el autor sobre la historia reciente de este tipo de estructuras y que cuenta con resultados previos como la ponencia presentada al Segundo Congreso Internacional de Historia de la Construcción sobre las realizaciones en los Países Bajos.
