Abstract: objectives: to estimate the prevalence of diagnosis of allergic asthma in patients with persistent asthma attending allergy or pneumology outpatient clinics and to describe the clinical management of asthma in these patients. methods: systematic random sampling was used to retrospectively include 382 patients aged between 12 and 65 years old with a diagnosis of persistent asthma (according to gina criteria) who had attended allergy or pneumology outpatient clinics during the previous year. allergic asthma was defined as the presence of sensitization to any common allergen according to the results of specific ige determinations and/or skin tests. data on the treatment of asthma were gathered. results: allergy studies were performed in 99.5% of the patients attending allergy centers and in 76.5% of those attending pneumology centers. a diagnosis of allergic asthma was made in 90.6% (95% ci: 86.5-94.7) and 46.1% (95% ci: 39.0-53.2), respectively. the prevalence of allergic asthma was highest in young male patients with less severe asthma. according to the gina criteria, 14.1% of patients from allergy centres and 23.0% of those from pneumology centers were classified as having severe persistent asthma. twenty-four percent of patients attending allergy clinics and 5.7% of those attending pneumology centers received bronchodilator treatment exclusively. conclusions: diagnosis of allergic asthma was much higher in allergy clinics than in pneumology centres. although some of this difference may be due to more frequent performance of allergy studies in allergy clinics, the most probable explanation lies in the differences observed in the profiles of patients attending the two types of center.

Palabra Clave , 2008,
Abstract: El presente artículo analiza el comportamiento y las actitudes adoptadas por la prensa espa ola durante el primer periodo de la transición a la democracia (noviembre de 1975-diciembre de 1978), momento en el que se realizaron los cambios políticos e institucionales más relevantes del proceso. Desde diversas perspectivas se explica el papel que jugaron los principales periódicos, así como las razones que les llevaron al consenso en los temas fundamentales de discusión pública. De esta forma, se constata cómo los medios de comunicación colaboraron de forma decisiva en la construcción de una nueva comunidad política democrática. A través de varios ejemplos de diarios, tomados uno por uno y en conjunto, se explican las especiales características de este interesante caso de colaboración entre poder político y periodismo, incluyendo algunas excepciones como la prensa de extrema derecha y los sectores nacionalistas vascos.
Trazado y construcción de arquerías en los inicios del gótico andaluz. Estudio del caso cordobés
García-Ortega, A. J.
Informes de la Construccion , 2012,
Abstract: The Gothic arcades of the Cordovan parishes are among the earliest in Andalusia. Their design, tracing, measure and construction can be studied thanks to their characteristics and affinities, while at the same time suggest that they follow the same preset criteria. The present work demonstrates the existence of preset criteria, which determined resistant sections that the Gothic masters considered suitable within certain margins. In fact they were using a structural oversizing, of which they were barely aware. This approach was constructively very efficient, showing the masters’ confidence in their craft, but it contravened the proportionality criteria of the time. In the design process, the masters used the metrical pattern established for the building to generate the main dimensions. Among these dimensions was the radius of curvature, which was often invariant to enable reuse of formwork and templates, the standardization of dowels, etc. Las arcadas góticas de las iglesias parroquiales cordobesas están entre las primeras levantadas en Andalucía. Sus características y afinidades permiten un amplio estudio sobre su dise o, trazado y medida, construcción, etc., a la vez que sugieren la hipótesis de que todos estos aspectos pudieron obedecer a unos mismos criterios preestablecidos. La investigación realizada lo corrobora, comprobando cómo derivaban en secciones resistentes que los maestros góticos consideraban válidas dentro de un rango de luces y cargas, aprovechando un sobredimensionamiento estructural del que apenas eran conscientes. Esto redundaba en una gran eficacia constructiva, demostrando su confianza en el oficio, aunque contradecía ciertos criterios de proporcionalidad al uso. En el proceso de dise o intervenía, determinantemente, el patrón métrico establecido para el edificio, generando las dimensiones fundamentales. Entre ellas estaban los radios de curvatura de los arcos, que se homogeneizaban para permitir la reutilización de cimbras y plantillas, la estandarización de dovelas, etc.
Una mezquita de nueve bóvedas en Córdoba. Estudio arquitectónico de un edificio desaparecido en 1725
García-Ortega, Antonio Jesús
Al-Qantara : Revista de Estudios Arabes , 2012,
Abstract: After the Castilian conquest of Córdoba in 1236, a small mosque next to the Guadalquivir River was converted into the parish church of San Nicolás de la Ajerquía. The building was extended until the mid-sixteenth century and repeatedly transformed over time. However, the ancient Islamic building existed until its demolition during the important reforms of the period 1725-1727. There are several documentary records of those years, and also a plan sketch preserved in the parish archive. However, this mosque has gone virtually unnoticed by the specialized historiography, perhaps because the limited and ambiguous data hinder a proper valuation of its architectural form. In this study the original drawing has been analyzed, contextualizing it with several plans and historical documents. This has produced a hypothesis about the size of the mosque’s prayer hall, its approximate orientation, as well as its interior architectural organization: an almost square plan, subdivided into nine areas covered with vaults. Therefore, it could be framed within a type of mosque detected long ago by Creswell, who called it “ninedome- mosque”. The building would be the only known example of such architectural type in Córdoba. Tras la conquista castellana de Córdoba, en 1236, la nueva parroquia de San Nicolás de la Ajerquía aprovechó como iglesia una peque a mezquita junto al río Guadalquivir. El edificio, ampliado a mitad del siglo XVI y reiteradamente transformado a lo largo del tiempo, mantuvo la preexistencia islámica hasta las importantes reformas del período 1725-27, que supusieron su total demolición. Pese a que existen varias alusiones documentales de aquellos a os y un dibujo a mano alzada de la planta conservado en el archivo parroquial, esta mezquita ha pasado prácticamente inadvertida en la historiografía especializada, quizás porque los escasos y ambiguos datos conocidos no permiten estimar su arquitectura. En este trabajo se analiza directamente el dibujo original, contextualizándolo con distintos planos y documentos históricos. Esto ha permitido formular una hipótesis sobre las dimensiones de la sala de oración de la mezquita, su orientación aproximada, así como sobre su conformación arquitectónica interior: una planta prácticamente cuadrada, organizada en nueve ámbitos con cierta autonomía espacial y cubiertos con bóvedas. Seguiría en esto a un tipo de mezquita hace tiempo detectada por Creswell, que la denominó nine-dome-mosque , y de la que sería el único ejemplo conocido en Córdoba.
Emerging archetypes in massive artificial societies for literary purposes using genetic algorithms

Computer Science , 2014,
Abstract: The creation of fictional stories is a very complex task that usually implies a creative process where the author has to combine characters, conflicts and plots to create an engaging narrative. This work presents a simulated environment with hundreds of characters that allows the study of coherent and interesting literary archetypes (or behaviours), plots and sub-plots. We will use this environment to perform a study about the number of profiles (parameters that define the personality of a character) needed to create two emergent scenes of archetypes: "natality control" and "revenge". A Genetic Algorithm (GA) will be used to find the fittest number of profiles and parameter configuration that enables the existence of the desired archetypes (played by the characters without their explicit knowledge). The results show that parametrizing this complex system is possible and that these kind of archetypes can emerge in the given environment.
Synoptic patterns associated with wildfires caused by lightning in Castile and Leon, Spain

Natural Hazards and Earth System Sciences (NHESS) & Discussions (NHESSD) , 2011, DOI: 10.5194/nhess-11-851-2011
Abstract: The Iberian Peninsula presents the highest number of wildfires in Europe. In the NW of Spain in particular, wildfires are the natural risk with the greatest economic impact in this region. Wildfires caused by lightning are closely related to the triggering of convective phenomena. The prediction of thunderstorms is a very complex task because these weather events have a local character and are highly dependent on mesoscale atmospheric conditions. The development of convective storms is directly linked to the existence of a synoptic environment favoring convection. The aim of this study is to classify the atmospheric patterns that provide favorable environments for the occurrence of wildfires caused by lightning in the region of Castile and Leon, Spain. The database used for the study contains 376 wildfire days from the period 1987–2006. NCEP data reanalysis has been used. The atmospheric fields used to characterise each day were: geopotential heights and temperatures at 500 hPa and 850 hPa, relative humidity and the horizontal wind at 850 hPa. A Principal Component Analysis in T-mode followed by a Cluster Analysis resulted in a classification of wildfire days into five clusters. The characteristics of these clusters were analysed and described, focusing particularly on the study of those wildfire days in which more than one wildfire was detected. In these cases the main feature observed was the intensification of the disturbance typical of the cluster to which the wildfire belongs.
Las elecciones europeas de 2009 en la prensa aragonesa

Revista Latina de Comunicación Social , 2012,
Abstract: Este artículo estudia los comicios al Parlamento Europeo de 2009, hito legislativo en el proceso de consolidación de la Unión Europea. En concreto, analiza y compara las coberturas periodísticas que los diarios de pago aragoneses otorgaron a la campa a electoral. Para ello se aplica un análisis de contenido cuantitativo a todos los artículos publicados durante los 15 días de campa a en Heraldo de Aragón, El Periódico de Aragón (ambos editados en Zaragoza), Diario del Altoaragón (editado en Huesca) y Diario de Teruel (editado en Teruel). Este análisis se centra especialmente en los protagonistas políticos de la cobertura con el objetivo de descubrir de quién informa la prensa regional para determinar si la cobertura de estas elecciones supranacionales se realiza en clave europea, nacional o aragonesa. La hipótesis de partida es que la prensa aragonesa se ocupa más de los líderes políticos a nivel nacional, aunque no se presenten a las elecciones, que de los candidatos que encabezan las listas de los partidos que concurren a estos comicios. Los resultados de esta investigación confirman esta hipótesis, ya que la cobertura de la campa a se definió en términos nacionales y estuvo protagonizada, sobre todo, por José-Luis Rodríguez-Zapatero y Mariano Rajoy.

Abstract: The most important hail event recorded in the region of the Ebro Valley (NE Spain) in 2004 was the 11 September episode. Large hailstones (some of them with a diameter of over 30 mm) caused important damages in agriculture and properties. The hail event affected an area of 3848 ha and was caused by several multicellular systems. The aim of this paper is the analysis of the associated convective structures using the meteorological radar as well as the MM5 mesoscale model, thermodynamic data and a hailpad network. To achieve this end, the new hailstorm analysis tool RHAP (Rainfall events and Hailstorms Analysis Program) has been applied. It identifies tracks and characterises precipitation systems and convective cells, taking into account 2-D and 3-D structures. The event has also been studied with the TITAN software (Thunderstorm Identification, Tracking, Analysis and Nowcasting) in an attempt to compare both methods. Results show that the episode had a strong convective activity with CAPE values over 4000 J/kg and with hail-forming cells characterised by VIL (Vertical Integrated Liguid) exceeding 40 kg/m2, VILD (VIL density) over 4 g/m3, HP (Hail Probability) of 100% and SHP (Severe Hail Probability) of over 75%. The hail cells evolved into multicellular systems that lasted between 70 and 90 min. Finally, the comparison of RHAP and TITAN has shown significant correlations between methods.
Amyloid Beta-Protein and Neural Network Dysfunction
Fernando Pe?a-Ortega
Journal of Neurodegenerative Diseases , 2013, DOI: 10.1155/2013/657470
Abstract: Understanding the neural mechanisms underlying brain dysfunction induced by amyloid beta-protein (Aβ) represents one of the major challenges for Alzheimer’s disease (AD) research. The most evident symptom of AD is a severe decline in cognition. Cognitive processes, as any other brain function, arise from the activity of specific cell assemblies of interconnected neurons that generate neural network dynamics based on their intrinsic and synaptic properties. Thus, the origin of Aβ-induced cognitive dysfunction, and possibly AD-related cognitive decline, must be found in specific alterations in properties of these cells and their consequences in neural network dynamics. The well-known relationship between AD and alterations in the activity of several neural networks is reflected in the slowing of the electroencephalographic (EEG) activity. Some features of the EEG slowing observed in AD, such as the diminished generation of different network oscillations, can be induced in vivo and in vitro upon Aβ application or by Aβ overproduction in transgenic models. This experimental approach offers the possibility to study the mechanisms involved in cognitive dysfunction produced by Aβ. This type of research may yield not only basic knowledge of neural network dysfunction associated with AD, but also novel options to treat this modern epidemic. 1. Introduction Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by severe cognitive impairments [1, 2]. Postmortem studies of brains from long-term AD patients have revealed the presence of senile plaques that contain the amyloid beta-peptide (Aβ) [3, 4]. Most studies of AD have focused on the biochemical mechanisms involved in the neurodegenerative processes triggered by the Aβ aggregates (for recent reviews, see [5, 6]). Such efforts have provided noteworthy evidence that has explained some aspects of the disease, mainly in its terminal stages; however, it has been difficult to link these findings to the known cognitive and behavioral symptoms that characterize the early stages of the disease. Moreover, new therapeutic approaches to treat AD based on this research have shown little or no benefit (for a recent review, see [7]). By looking at the cellular mechanisms involved in AD physiopathology from another perspective, it is becoming clear that cognitive decline associated with AD, or with any other neurological disease, should be examined in the context of the related neural network dysfunctions [1, 2, 8–10]. This approach, which might look novel for AD, has had proven success for the
