Contribución a la geología de la Zona Axial Pirenaica, valles del Cinca y Esera, provincia de Huesca

En este trabajo se describen las series del Paleozoico, su estructura, y sus relaciones con los granitoides.Los terrenos más antiguos atribuidos al Cambro Ordovícico constituyen una potente serie arenoso-pelítica aflorante en la zona norte del estudio. El Silúrico está formado por pizarras grafitosas de espesor variable. El Devónico comienza por un episodio carbonatado alternante con pizarras en la parte inferior. Tras un breve tramo de pizarras viene una caliza «pseudegriotte» del Devónico medio érroneamente atribuida al nivel terminal del Devónico en algunos trabajos anteriores. A continuación hay un desarrollo considerable de pizarras, a veces con tramos de finos niveles arenosos, que hay que incluir en el Devónico y no en el Carbonífero como anteriormente se hacía, habiéndose detectado con fósiles las verdaderas calizas del tránsito del Devónico al Carbonífero. El Carbonifero detrítico queda asi restringido a su facies característica con gruesos bancos de areniscas y grauwacas.El magmatismo granítico es contemporáneo de la mayoría de las fases de plegamiento hercínico. La fase 2 principal tiene direcciones N90-120 E y pliegues tendidos vergentes al Sur de geometría similar. Anteriormente se deduce la existencia de una fase 1 transversa. La fase 2 coincide con el máximo de metamorfismo regional, de baja presion, que llega al grado de la silimanita en niveles profundos. En este momento probablemente empieza la granitización (macizo de Lys y posiblemente macizo de Bielsa).Las estructuras de la fase 3 están condicionadas por la presencia del macizo de Lys elevado por una falla dúctil y por los granitos en trance de intrusión (Posets) en desequilibrio térmico con el encajante.El metamorfismo de contacto ocasiona, en su área, una inversión en el signo del contraste de competencias entre los niveles calizos y los pelíticos que se manifiestan en deformaciones, aún más tardías, en las que la caliza (mármol) se comporta de manera fluida respecto a la corneana rígida. Estos movimientos se deberían a reajustes últimos de los granitos.Finalmente se describe la influencia de la tectónica alpina

Control strategies for Energy Recovery Ventilators in the South of Europe for residential nZEB. Quantitative analysis of the air conditioning demand

Mechanical ventilation systems are essential for ensuring the indoor quality of air in nZEB (nearly Zero Energy Buildings) with a high level of airtightness. In cold countries, it has already been demonstrated that Heat Recovery Ventilators (HRV) recovering the sensible energy from air ventilation are needed to achieve the energy demand goals for nZEB set by Passivhaus. In tropical areas with hot temperatures and high relative humidity in the ambient air, the necessity of recovering latent and sensible energy with Energy Recovery Ventilators (ERV) has also been demonstrated. However, in warm climates with medium relative humidity levels, for example in cities located on the Mediterranean coast, the evaluation of the effectiveness of an EVR for residential buildings has to be analyzed and optimized. This article establishes the effectiveness of several control strategies for ventilation air systems including ERV with the aim of optimizing the air conditioning energy demand of dwellings located in several cities in the South of Europe. Possible control strategies have been analyzed to minimize the undesirable operation of ERVs which could otherwise increase the air conditioning energy demand for winter and summer seasons. The impact of the latent effectiveness and the effect of free-cooling on the air conditioning energy demand is also studied

The Impact of Eco-Innovation on Performance Through the Measurement of Financial Resources and Green Patents

The main objective of this article is to contribute empirically to the understanding of the impact that eco-innovation has on firms’ financial performance within the framework of the resources-based view. Specifically, eco-innovation is measured by using eco-innovative activities and financial resources applied to eco-innovation to argue that the identification and measurement of certain resources of firms allow companies that are particularly active in investing in eco-innovation to be more competitive. Furthermore, the analysis attempts to ascertain whether firms that own green patents and other characteristics exhibit different level of financial performance than firms without registered green patents. The empirical partial least squares structural equation modeling results indicate a positive relationship between the investment of resources and the financial performance of eco-innovative firms. The effects of involving managers in eco-innovative processes as an environmental capability of firms are also tested

Long term management of obstructive sleep apnea and its comorbidities

Obstructive sleep apnea (OSA) is a worldwide highly prevalent disease associated with systemic consequences, including excessive sleepiness, impairment of neurocognitive function and daytime performance, including driving ability. The long-term sequelae of OSA include and increase risk for cardiovascular, cerebrovascular and metabolic syndrome disorders that ultimately lead to premature death if untreated. To ensure optimal long-term outcomes, the assessment and management of OSA should be personalized with the involvement of the appropriate specialist. Most studies have demonstrated inmediate improvement in daytime somnolence and quality of life with CPAP and other therapies, but the effect of long-term treatment on mortality is still under debate. Currently, the long-term management of OSA should be based on a) identifying physiological or structural abnormalities that are treatable at the time of patient evaluation and b) comprehensive lifestyle interventions, especially weight-loss interventions, which are associated with improvements in OSA severity, cardiometabolic comorbidities, and quality of life. In long-term management, attention should be paid to the clinical changes related to a potential reoccurrence of OSA symptoms and it is also necessary to monitor throughout the follow up how the main associated comorbidities evolve

El tratamiento informativo de las víctimas de violencia de género en Euskadi: Deia, El Correo, El País y Gara (2002-2009)

En este artículo se analizan las informaciones publicadas en los diarios Deia, El Correo, El País y Gara sobre víctimas mortales de la violencia de género en el País Vasco durante el período 2002-2009. El objetivo del estudio es, por una parte, contrastar las recomendaciones que sobre el tratamiento informativo de la violencia de género se han hecho desde diferentes organismos y su reflejo en la práctica informativa y, por otra, comparar las distintas estrategias discursivas en cada uno de los medios. Dicha investigación se enmarca dentro de un estudio más amplio sobre el tratamiento de la violencia en la prensa financiado por el MICINN, (referencia CSO2010-19855)
