Electoral debates in the VODs of the Public RTVs of Europe

Introducción: En los medios públicos, el debate electoral es de especial interés por las reglas que deben adoptar estas televisiones para cumplir con sus compromisos de servicio público y mantener los valores de diversidad, universalidad y participación. En el nuevo escenario que plantean las plataformas propias de VOD la inclusión de estos debates electorales televisados y las variaciones en su formato se plantea como un ejercicio de transparencia y un compromiso con la memoria audiovisual del país que refuerza los valores de diversidad, proximidad y universalidad representativa. Metodología: El artículo revisa de un modo comparativo el uso de este formato en siete de las principales emisoras públicas de televisión de Europa siguiendo los modelos de Hallin y Mancini y con una subdivisión regional dentro del modelo democrático-corporatista para obtener resultados con un corte étnico-político. Resultados y conclusiones: Existe una notable disparidad entre las televisiones públicas que tienen accesibles los debates electorales en sus plataformas de VOD. El análisis desvela que, a pesar de su trascendencia, los debates no se encuentran disponibles en los entornos online del medio, aunque sí son accesibles desde plataformas ajenas, principalmente YouTubeEste artículo forma parte de las actividades del proyecto de investigación (RTI2018-096065-B-I00) del Programa Estatal de I+D+i orientado a los Retos de la Sociedad del Ministerio de Ciencia , Innovación y Universidades y del Fondo Europeo de Desarrollo Regional (FEDER) sobre Nuevos valores, gobernanza, financiación y servicios audiovisuales públicos para la sociedad de Internet: contrastes europeos y españoles.

Northern Shrimp (Pandalus borealis, Krøyer) from EU-Spain Bottom Trawl Survey 2018 in NAFO Div. 3LNO

The Spanish Institute of Oceanography carried out in 2018 two bottom trawl surveys in the NAFO Regulatory Area in Division 3NO and 3L during the months of June and August respectively. The results on Northern shrimp (Pandalus borealis) are presented and compared with those from previous surveys from the same series. As recent years in 2018the shrimp catch (0.528 kg.) and estimated biomass (2.413 t.) in Divisions 3NO remain between the lowest of the series, confirming the decrease of shrimp importance from 2004. The Northern shrimp catches in 3L Division have declined from 2009, the shrimp catch (1352 kg.) and biomass estimated in 2018 (7807 t.) remain between the lowest values in the historical series

Custodios de la memoria migrante: clasificación de los fondos del Centro de Estudios de la Emigración Castellana y Leonesa

El archivo del Centro de Estudios de la Emigración Castellana y Leonesa (en adelante CEECyL), fundado en 2011 y adscrito al Centro Asociado de la UNED en Zamora, recoge los fondos documentales recuperados a raíz de las investigaciones que el Centro Asociado ha venido desarrollando desde los años 90. Como la mayoría de entidades de este tipo, constituye una especie de “archivo de archivos”, puesto que en sus diferentes secciones conserva un abundante y variado acervo documental sobre las migraciones de los castellanos y leoneses a lo largo de la historia. Dadas las circunstancias en que se ha ido formando, destacan en sus fondos los documentos personales, especialmente los memorialísticos (historias de vida), así como la documentación societaria de las diferentes asociaciones castellanas y leonesas en América

Prevalence of convergence insufficiency among Spanish school children aged 6 to 14 years

Clinical relevance: Convergence insufficiency (CI) at an early age can lead to learning difficulties affecting school performance. The aim of this study was to examine the prevalence of CI in a non-clinical population of Spanish children using well defined clinical criteria and to determine whether sex is a risk factor. Methods: Visual acuity and binocular vision tests were performed in 628 children aged 6-14 years (mean age 9.6 ± 1.3 years) at three schools in the Madrid Community, Spain. To assess CI prevalence we used CITT (Convergence Insufficiency Treatment Trial) criteria. The three signs considered were: i) exophoria at least 4∆ greater at near than at far; ii) near break point of convergence (NPC) ≥ 6 cm; and iii) reduced positive fusional vergence (PFV) at near (≤ 15∆ base-out break or failed Sheard's criterion). Results: The CI prevalence detected was 5.30% (33 children). Proportions of children with one or two signs of CI were 23.76% (148 children) and 12.20% (76 children), respectively. No differences in these CI rates by sex were detected. Conclusion: The clinically significant CI prevalence observed here suggests the need for more binocular vision screening programmes in school settings.Depto. de Optometría y VisiónFac. de Óptica y OptometríaTRUEpu

Numerical simulations of the aerodynamic response of circular segments with different corner angles by means of 2D URANS. Impact of turbulence modeling approaches

[Abstract:] This paper presents the results of numerical and experimental investigations on the force coefficients and Strouhal numbers of circular segments considering different corner angles or chord to sagitta ratios. The research is motivated because these geometries are becoming increasingly popular in several engineering disciplines. The so-called D-section (semi-circular cylinder with a corner angle of 90◦) has been experimentally studied in the past, since it is a galloping prone geometry. However, there is a lack of research for cases with different corner angles, and the numerical investigations related to this topic are particularly scarce. In this work, a 2D Unsteady Reynolds Averaged Navier–Stokes approach has been adopted aiming to study the circular segments at the sub-critical regime, considering corner angles from 40◦ to 90◦, and the flow parallel to the rectilinear side. These sections were found to be particularly challenging since they present massive flow separation on the rectilinear side, alongside the inherent difficulties related to modeling the flow along curved surfaces at high Reynolds numbers. The impact of introducing low-Reynolds-number and curvature corrections in the k − ω SST turbulence model and the performance of the Transition SST model have been extensively studied.The research leading to these results has received funding from the Spanish Minister of Economy, Industry and Competitiveness (MINECO) with project reference BIA2013-41965-P.

Results of Exploratory Deep-sea Fishing Survey in the Galician Bank: Biological Aspects on Some of Seamount-associated Fish (ICES Division IXb)

Since October 1998 to October 1999 an experimental survey, comprising 12 monthly fishing trips were carried out in Galician Bank (ICES Divisions IXb) by two commercial trawlers of the Spanish fleet. The aims of this survey were to explore the fishing resources of studied area and to know the species community associated to this seamount. A total of 297 valid hauls were made during 309 hours of fishing and yielded a total catch of 45 145 kg in the depth strata studied (650-1200 m). The community of species in the area prospected presented high species richness. A total of 106 species were made up of 70 teleosts, 11 sharks, 3 rays, 2 chimaeras, 11 crustacea, 6 molluscs and 3 equinoderms The most important species captured were teleosts: H. mediterraneus, M.moro, L. eques, A. bairdii, E. telescopus, T. cristulata and L. piscatorius, followed for deep sharks: D. licha, D. calceus and crustacean: Ch affinis. The yields obtained for the whole series of fishing trips were low being the values obtained by order of importance: 30.3, 14.0, 13.1, 11.7, 4.8, 4.2, 2.5 kg/h and 1 kg/h for the teleosts; 2.0, 1.7, kg/h for sharks and 1.2 kg/h for crustacean. The results indicate, in general, there were no differences in depth distribution of the species characterised by the presence or absence of certain species and also, a seasonal variation in the abundance of the most important caught

Characteristics and Behavior of Di erent Catalysts Used for Water Decontamination in Photooxidation and Ozonation Processes

The objective of this study was to summarize the results obtained in a wide research project carried out for more than 15 years on the catalytic activity of di erent catalysts (activated carbon, metal–carbon xerogels/aerogels, iron-doped silica xerogels, ruthenium metal complexes, reduced graphene oxide-metal oxide composites, and zeolites) in the photooxidation (by using UV or solar radiation) and ozonation of water pollutants, including herbicides, naphthalenesulfonic acids, sodium para-chlorobenzoate, nitroimidazoles, tetracyclines, parabens, sulfamethazine, sodium diatrizoate, cytarabine, and surfactants. All catalysts were synthesized and then texturally, chemically, and electronically characterized using numerous experimental techniques, including N2 and CO2 adsorption, mercury porosimetry, thermogravimetric analysis, X-ray di raction, Fourier-transform infrared spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, di use reflectance UV–vis spectroscopy, photoluminescence analysis, and transmission electron microscopy. The behavior of these materials as photocatalysts and ozonation catalysts was related to their characteristics, and the catalytic mechanisms in these advanced oxidation processes were explored. Investigations were conducted into the e ects on pollutant degradation, total organic carbon reduction, and water toxicity of operational variables and the presence of di erent chemical species in ultrapure, surface, ground, and wastewaters. Finally, a review is provided of the most recent and relevant published studies on photocatalysis and catalyzed ozonation in water treatments using similar catalysts to those examined in our project.Spanish Ministry of Economy, Industry and Competitiveness CTQ2016-80978-C2-1-REuropean Union (EU) CTQ2016-80978-C2-1-RJunta de Andalucía P18-RT-419

Anthropometric Profile Assessed by Bioimpedance and Anthropometry Measures of Male and Female Rugby Players Competing in the Spanish National League

Different rugby positions make different demands on players. It therefore follows that optimum body composition may vary according to the position played. Using anthropometry and bioimpedance analysis (BIA) to assess body composition, the present study aimed to compare the effect of sex and position on body composition variables using anthropometry and BIA methods. A total of 100 competitive rugby players (35 women and 65 men) competing in the First Spanish National League were recruited voluntarily and for convenience for this study. In the laboratory, body composition was assessed by anthropometry, following the recommendations established by the International Society for the Advancement of Kinanthropometry (ISAK), and by direct segmental multi-frequency BIA, following the guidelines established by the Spanish Group of Kinanthropometry (GREC) of the Spanish Federation of Sports Medicine (FEMEDE). We found sex-related differences in height, weight, body mass index and body fat (%) by anthropometry and in body lean mass (%) by DSM-BIA, in 4 of the 6 skinfolds assessed (p < 0.05). We also observed position-related differences in all the variables assessed (p < 0.05) except for lean body mass, as measured by both methods of determining body composition, and front thigh skinfold. Body composition and ∑6skinfolds differs according to sex and playing position, backs (16.6 ± 3.8% and 92.3 ± 33.9 mm,) vs. forwards (20.0 ± 6.7 and 115.3 ± 37.6 mm), and the muscle-adipose (meso-endomorphic somatotype) development predominated in both sexes. Thus, forwards of both sexes are taller, heavier and fatter, possibly due to the specific demands of this position. In addition, body composition measurements vary according to the method used (DSM-BIA vs. anthropometry), indicating that anthropometry is probably the best body composition assessment method
