    The present study aims to analyse the atmospheric dynamics of the Santa Cruz de Tenerife region (Tenerife, Canary Islands). This area is defined by the presence of anthropogenic emissions (from a refinery, a port and road traffic) and by very specific meteorological and orographic conditions-it is a coastal area with a complex topography in which there is an interaction of regional atmospheric dynamics and a low thermal inversion layer. These factors lead to specific atmospheric pollution episodes, particularly in relation to SO2 and PM10. We applied a methodology to study these dynamics based on two complementary approaches: 1) the analysis of the observations from the air quality network stations and 2) simulation of atmospheric dynamics using the WRF-ARW/HERMESv2/CMAQ/BSC-DREAM8b and WRF-ARW/HYSPLIT modelling systems with a high spatial resolution (1×1km2). The results of our study show that the refinery plume plays an important role in the maximum SO2 observed levels. The area of maximum impact of the refinery is confined to a radius of 3km around this installation. A cluster analysis performed for the period: 1998-2011 identified six synoptic situations as predominant in the area. The episodes of air pollution by SO2 occur mainly in those with more limited dispersive conditions, such as the northeastern recirculation, the northwestern recirculation and the western advection, which represent 33.70%, 11.23% and 18.63% of the meteorological situations affecting the study area in the year 2011, respectively. In the case of particulate matter, Saharan dust intrusions result in episodes with high levels of PM10 that may exceed the daily limit value in all measurement station; these episodes occur when the synoptic situation is from the east (3.29% of the situations during the year 2011). © 2013 Elsevier B.V.

    Emission models play a key role in the development of high-resolution air quality modelling systems (AQMS). To minimise the uncertainty presented by these models, it is essential to match the high-resolution requirements of chemical transport models (CTMs) and to use up-to-date information and emission methodologies. During 2005 and 2006, the Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS) developed the High-Elective Resolution Modelling Emissions System (HERMES04), which is a model that estimates anthropogenic and biogenic emissions for Spain with a temporal and spatial resolution of 1h and 1km2, taking 2004 as the reference period. Due to both the changes in Spanish emissions patterns and the age of the activity data and methodologies used, it has become necessary to update and improve the whole system. Hence, a new high-resolution emission model for Spain (HERMESv2.0) has been developed. This work introduces the improved emission estimation methodologies and data on which the model is based, as well as an analysis of the results obtained. The annual emissions estimated by HERMESv2.0 for Spain in 2009 are: NOx, 924kt; NMVOCs, 2331kt; SO2, 278kt; CO, 2178kt; NH3, 339kt; PM10, 139kt; and PM2.5, 105kt. Compared with HERMES04, major differences are found in NMVOCs (+1172kt) and SO2 (-870kt). Important changes inemission patterns are also observed in terms of spatial and temporal distributions. A numerical comparison of both models with the Spanish National Emission Inventory indicates that previous underestimations have been heavily reduced in HERMESv2.0, especially for NOx (from -669kt·year-1 to -176kt·year-1), CO (from -761kt·year-1 to 271kt·year-1) and NMVOCs (from -1217kt·year-1 to 135kt·year-1). The new model substitutes HERMES04 as the emission core of the operational air quality forecasting system for Spain CALIOPE.

    El incremento de la utilizaci on de la energ a solar como fuente de generaci on de energ a requiere de una adecuada estimaci on de la radiaci on solar global y directa incidente en la super cie terrestre. La estimaci on de la radiaci on global se realiza mediante simulaciones de modelos num ericos de pron ostico meteorol ogico que contienen la informaci on sobre la variabilidad de las condiciones temporales, geogr a cas y atmosf ericas. Dicha estimaci on representa la base del pron ostico de la radiaci on solar para aplicaciones energ eticas. Sin embargo, los esquemas de transferencia radiativa implementados en los modelos meteorol ogicos, evidencian limitaciones en el c alculo de la radiaci on y extinci on atmosf erica con errores sistem aticos en la simulaci on de la radiaci on solar. Esta tesis presenta el desarrollo de un sistema de pron ostico de radiaci on solar basado en simulaciones del modelo meteorol ogico de meso-escala WRF-ARW, correcci on del Bias de la radiaci on global mediante t ecnicas de post-proceso y estimaciones de radiaci on directa a partir de un modelo param etrico. El modelo WRF-ARW es aplicado con una resoluci on espacial de 4kmx4km y temporal horaria sobre la pen nsula Ib erica. La evaluaci on anual de las simulaciones del modelo mediante 114 estaciones radiom etricas distribuidas en España para el año 2004, muestra un rMBE de 9.8 %, un rRMSE de 51% y un coe ciente de correlaci on r de 0.89 con los errores m as signi cativos en primavera (rMBE=14 %, rRMSE=42% y r=0.89) y verano (rMBE=11 %, rRMSE=37% y r=0.91). La sobrestimaci on para condiciones de cielo despejado es superior a 80 W m_2 y la subestimaci on con valores inferiores a -80 W m_2 se presenta en condiciones de cielo completamente nublado para todo el rango del vector posici on del Sol entre el horizonte y el cenit. Las t ecnicas de post-proceso implementadas y evaluadas en el Noreste de España (Cataluña) a trav es de 90 estaciones radiom etricas son: Model Output Statistics (MOS), Arti cial Neural Networks (ANN), Kalman Filter (KF) y m etodo Recursivo (REC). A partir de la revisi on bibliogr a ca, dichas t ecnicas son utilizadas para minimizar los errores sistem aticos de los pron osticos debido a las diferencias entre los resultados de las simulaciones y las observaciones. Con el prop osito de obtener los mejores resultados, se han combinado los post-procesos KF y MOS, los cuales presentan un rMBE anual promedio de 1.2%, un rRMSE de 43% y un coe ciente de correlaci on de 0.92. Los porcentajes de correcci on anual son de 87% y 17% para el Bias y el RMSE, respectivamente. Para la estimaci on de la radiaci on solar directa y las horas de Sol, se han evaluado cinco modelos de descomposici on param etrica. El modelo param etrico de Macagnan que presenta el mejor comportamiento, realiza la estimaci on a partir del ndice de transparencia atmosf erica calculado mediante la radiaci on global corregida por los post-procesos KF y MOS. Las correcciones de la radiaci on global, la estimaci on de la radiaci on directa y la contabilizaci on de las horas de Sol, son interpolados espacialmente a trav es del m etodo geoestad stico de Kriging. Los resultados son evaluados para analizar las limitaciones de la interpolaci on en funci on al comportamiento geogr a co y atmosf erico de la zona de estudio. Finalmente, el sistema es aplicado y evaluado en 48h de pron ostico del año 2009. Los resultados permiten analizar las correcciones de los post-procesos y las estimaciones de la radiaci on directa a partir de los elementos establecidos en el sistema de pron ostico con un alcance temporal de 48h. La aplicaci on de estas metodolog as en un sistema de pron ostico permite analizar el impacto de la correcci on del Bias, la estimaci on de la radiaci on directa y las horas de Sol a partir de simulaciones de pron ostico meteorol ogico. Por lo tanto, los resultados proporcionan un relevante aporte para futuras aplicaciones de pron osticos de la radiaci on solar en este sector energ etico.

    The increased contribution of solar energy in the power generation resources requires an accurate estimation of global and direct beam solar radiation incident on the earth's surface. The estimation of global radiation is performed by means of numerical weather prediction models that include all the information to solve the temporal, geographical and atmospheric conditions variability. Being this the basis of the forecast of solar radiation for energy applications. However, the radiative transfer schemes implemented in meteorological models show limitations in the estimation of atmospheric radiation and extinction, with systematic errors in the simulation of solar radiation. This thesis presents the development of a forecasting system based on solar radiation simulations of the WRF-ARW meteorological mesoscale model, Bias corrections of global radiation from post-processing techniques and direct beam radiation estimations using a parametric model. The WRFARW model is applied in the Iberian peninsula with a spatial resolution of 4kmx4km and hourly temporal resolution. The annual evaluation of the model using 114 radiometric stations in Spain for the year 2004, shows rMBE of 9.8%, rRMSE of 51% and correlation coe cient r of 0.89 with the most signi cant errors in spring (rMBE=14 %, rRMSE=42% and r=0.89) and summer (rMBE=11 %, rRMSE=37% and r=0.91). The overestimation for clear sky conditions is over 80 W m_2 and the underestimation below -80 W m_2 are presented in overcast sky conditions for the entire range of Sun's position vector between the horizon and the zenith. The post-processing techniques implemented and evaluated in northeastern Spain (Catalonia) through 90 radiometric stations are: Model Output Statistics (MOS), Arti cial Neural Networks (ANN), Kalman Filter (KF) and Recursive method (REC). These techniques selected from the literature are used to minimize the systematic errors of the forecasts due to di erences between the results of simulations and observations. Combination of the techniques has also been analyzed, being the KF and MOS post-processes those with the best results in annual average with a rMBE of 1.2 %, rRMSE of 43% and correlation coe cient of 0.92. The annual rates of correction are 87% and 17% for Bias and RMSE, respectively To estimate direct beam radiation and sunshine hours, ve parametric models have been evaluated. The Macagnan model showed the best performance. The estimation is performed from the atmospheric transparency index calculated through global radiation corrected by KF and MOS post- processes. The Bias corrections of global radiation, estimations of direct beam radiation and sunshine hours are spatially interpolated through geostatistical method of Kriging. The results are evaluated to analyze the strengths and weaknesses of interpolation according to geographic and atmospheric behavior of the study area. Finally, the system is implemented and evaluated over 48h forecast of year 2009. The results have provided a valuable set of data to analyze the Bias correction of post-processes and the estimation of direct beam radiation from the elements of the forecast system with 48 hours ahead. The implementation of these methodologies on a forecasting system allows the impact analysis of bias correction, estimation of direct beam radiation and sunshine hours from meteorological forecast simulations. Thus, the results provide a relevant contribution for future applications of solar radiation forecast on solar radiation energy sector.

    CALIOPE is a high-resolution air quality system which provides forecast for 24 and 48h since October 2006 for Europe (12 km x 12 km, 1h) and Spain (4 km x 4 km, 1h). The meteorological model is the WRF-ARW model (version 3.2.1) initialized by the FNL/NCEP data. The emissions are estimated by means a top-down approach implemented in the High-Elective Resolution Modeling Emission System (HERMES version 2.0) based on the EMEP inventory for the year 2008. The Chemical Transport Model (CTM) is the CMAQ (version 4.5) using the CB-IV chemical mechanism and AERO4 mode for aerosols. Several evaluation studies and near-real time evaluation (NRT) against air quality measurements on an hourly basis support the confidence on the system. The present contribution evaluates the CALIOPE system over Europe using CMAQ CTM version 5.0 (CB05 and AERO5) which is working in forecast mode since 9 April 2012. The comparison between both CMAQ versions is done in terms of gaseous and aerosol concentrations (O3, NO2, SO2, PM10, and PM2.5) at the lowest level. Forecast concentrations are compared against observations on an hourly basis from the European air quality database (Airbase) which classifies stations as background rural/suburban. Results indicate that CMAQv5.0 improves O3 forecast daily cycle, especially at nighttime over suburban stations, where O3 biases are reduced between 20 and 40 µgm-3. The CMAQv5.0 improves the forecast of NO2 peaks at suburban stations reducing biases ~10-20 µgm-3. PM10 forecast also improves with the new CMAQ version. Episodes of secondary aerosol formation are now reproduced (i.e. 7-14 may 2012), where bias are reduce in ~10-20 µgm-3. Furthermore, PM10 hourly peaks in suburban stations are better reproduced reducing hourly biases ~5-10 µgm-3. The contribution also evaluates the effect of using the Kalman filter post-process to reduce systematic bias in both CMAQ versions. Results show that the bias-adjustment technique is more effective over CMAQv5.0.

    En las últimas décadas Europa ha presentado un claro progreso en la reducción de las emisiones antropogénicas. Sin embargo, la contaminación atmosférica continúa siendo un problema para la salud, especialmente en ambientes urbanos. El material particulado (PM), el dióxido de nitrógeno (NO2) y el ozono troposférico (O3) son los principales contaminantes con problemas en Europa y España. La directiva europea 2008/50/EC establece la posibilidad de usar técnicas de modelización que permitan incrementen el conocimiento sobre el transporte y la dinámica de contaminantes en la atmósfera para asegurar el cumplimiento de la legislación e informar a la población acerca de sus niveles. En este sentido, el sistema de pronóstico de la calidad del aire CALIOPE lleva trabajando en modo operacional ofreciendo pronósticos de la dinámica de la contaminación atmosférica en Europa y España desde octubre de 2006. CALIOPE incorpora el estado actual de conocimiento sobre la modelización de la física y química de la atmosfera, así como un modelo de emisiones específicamente desarrollado para España (HERMES). En este trabajo se describen las principales características actuales del sistema de pronóstico de calidad del aire CALIOPE en cuanto a su configuración, utilidad y funcionamiento como herramienta de pronóstico

    In this thesis the finite and spectral element methods (FEM and SEM, respectively) applied to problems in atmospheric simulations are explored through the common thread of Variational Multiscale Stabilization (VMS). This effort is justified by three main reasons. (i) the recognized need for new solvers that can efficiently execute on massively parallel architectures ¿a spreading framework in most fields of computational physics in which numerical weather prediction (NWP) occupies a prominent position. Element-based methods (e.g. FEM, SEM, discontinuous Galerkin) have important advantages in parallel code development; (ii) the inherent flexibility of these methods with respect to the geometry of the grid makes them a great candidate for dynamically adaptive atmospheric codes; and (iii) the localized diffusion provided by VMS represents an improvement in the accurate solution of multi-physics problems where artificial diffusion may fail. Its application to atmospheric simulations is a novel approach within a field of research that is still open. First, FEM and VMS are described and derived for the solution of stratified low Mach number flows in the context of dry atmospheric dynamics. The validity of the method to simulate stratified flows is assessed using standard two- and three-dimensional benchmarks accepted by NWP practitioners. The problems include thermal and gravity driven simulations. It will be shown that stability is retained in the regimes of interest and a numerical comparison against results from the the literature will be discussed. Second, the ability of VMS to stabilize the FEM solution of advection-dominated problems (i.e. Euler and transport equations) is taken further by the implementation of VMS as a stabilizing tool for high-order spectral elements with advection-diffusion problems. To the author¿s knowledge, this is an original contribution to the literature of high order spectral elements involved with transport in the atmosphere. The problem of monotonicity-preserving high order methods is addressed by combining VMS-stabilized SEM with a discontinuity capturing technique. This is an alternative to classical filters to treat the Gibbs oscillations that characterize high-order schemes. To conclude, a microphysics scheme is implemented within the finite element Euler solver, as a first step toward realistic atmospheric simulations. Kessler microphysics is used to simulate the formation of warm, precipitating clouds. This last part combines the solution of the Euler equations for stratified flows with the solution of a system of transport equations for three classes of water: water vapor, cloud water, and rain. The method is verified using idealized two- and three-dimensional storm simulations.

    The morphological study of the Odontocete organ of Corti including possible pathological features resulting from sound over-exposure, represent a key conservation issue to assess the effects of acoustic pollution on marine ecosystems. Through the collaboration with stranding networks belonging to 26 countries, 150 ears from 13 species of Odontocetes were processed. In this dissertation, we present a standard protocol to 1) compare the ultrastructure of the cochlea in several Odontocete species and 2) investigate possible damage as a consequence of sound exposure, using scanning (SEM) and transmission (TEM) electron microscopy, and immunohistochemistry. In a preliminary study, computerized tomography scans were performed before decalcification with ears of 15 odontocete species, proposing a set of standard measurements which classified very well the species. In addition, the constant ratio between measurements of inner and middle ear structures contributed to confirm the active role of the odontocete middle ear in sound reception mechanism. We established a decalcification protocol using the fast commercial decalcifier RDO® and EDTA (Ethylendiaminetetraacetic acid). Although further experiments should be conducted to assess the suitability of using one or the other method (because the number of samples treated with EDTA was comparatively small), RDO® at specific dilutions decreased the decalcification time of cetacean ear bones with control of the decalcification endpoint, helping a faster access to inner structures. The complementary use of electron microscopy and immunofluorescence allowed the description in odontocetes of new morphological features of tectorial membrane, spiral limbus, spiral ligament, stria vascularis, hair cells and their innervation. Furthermore, this study revealed qualitative and quantitative morphological characteristics of the organ of Corti in high-frequency hearing species, including 1) an outer hair cell (OHC) small length, 2) a thick cuticular plate in OHC, and a thick reticular lamina, 3) robust cup formation of the Deiters cell body, 4) the high development of cytoskeleton in Deiters and pillar cells and 5) the basilar membrane high stiffness. Interestingly, all these features, including a common molecular design of prestin, are also shared by echolocating bats, suggesting a convergent evolution in echolocating species. The presence of scars among hair cell rows, the pattern of stereocilia imprints in the tectorial membrane and the condition of fibrocytes II and IV were criteria suitable to determine or discard possible acoustic trauma, despite the numerous artefacts that rapidly develop as a consequence of tissue autolysis. Consequently, matching the preliminary approximation of the cochlear frequency map with the damaged region would bring information on the sound source that would have triggered a possible lesion.

    Controlled Exposure Experiments revealed lesions in the statocysts of four cephalopod species of the Mediterranean Sea (Sepia officinalis, Loligo vulgaris, Illex coindetii and Octopus vulgaris), when exposed to relatively low intensity low frequency sounds. The analysis was performed through: scanning (SEM) and transmission (TEM) electron microscopy techniques of the whole inner structure of the cephalopod statocysts, especially on macula and crista; SEM of the epidermal lines of cephalopod hatchlings; and proteomic studies (2DE/MALDI –MS) of the statocyst’s endolymph. All exposed adult individuals presented the same lesions and the same incremental effects over time, consistent with a massive acoustic trauma observed in land species that were exposed to much higher intensities of sound. Immediately after exposure, the damage was observed in the macula statica princeps (msp) and in the crista sensory epithelium. Kinocilia on hair cells were either missing or were bent or flaccid. A number of hair cells showed protruding apical poles and ruptured lateral plasma membranes, most probably resulting from the extrusion of cytoplasmic material. Hair cells were also partially ejected from the sensory epithelium, and spherical holes corresponding to missing hair cells were visible in the epithelium. The cytoplasmic content of the damaged hair cells showed obvious changes, including the presence of numerous vacuoles and electron dense inclusions not seen in the control animals. The appearance of these lesions became gradually more pronounced in individuals after 12, 24, 48, 72, and 96 hours. Special attention was given to validate these findings with control animals that were caught, maintained and sequentially sacrificed following the same protocol as the exposed individuals. The statocyst ultrastructure was therefore revisited and a comparative analysis was carefully conducted to assess the lesions triggered by the exposure to noise This study also presents preliminary results of the sound effects on epidermal lines of cephalopod hatchlings. The lesions, consistent with an acoustic trauma, were identic in the three species that were exposed, but their evolution over time, in opposition with what was observed in the statocysts, were different, suggesting that the animal size and metabolic response might play a role in a possible recovery process. The analysis of noise effects in the statocyst endolymph by proteomic techniques was only conducted on Sepia officinalis. The presence of differential staining of gels from control and subjected to sound exposure individuals demonstrate that the injuries could be related to a possible physiological imbalance that would affect the protein levels of the endolymph. The lesions and findings described here are new to cephalopod pathology. Given that lowfrequency noise levels in the ocean are increasing (e.g. due to shipping, offshore industry, and naval maneuvers), that the role of cephalopods in marine ecosystems is only now beginning to be understood, and that reliable bioacoustic data on invertebrates are scarce, the present study and future investigations will bring an important contribution to the sustainable use of the marine environment.

    Després de sotmetre'ls a experiments d'exposició controlada a sons de baixa intensitat i baixa freqüència es van observar lesions en els estatocists de quatre espècies de cefalòpodes de la mar Mediterrània (Sepia officinalis, Loligo vulgaris, Illex coindetii i Octopus vulgaris). L'anàlisi es va realitzar per mitjà de de microscòpia electronica d'escombratge (SEM) i de transmissió (TEM) de tota l'estructura interna de l'estatocist dels cefalòpodes, especialment en la màcula i en la crista, per SEM de les línees epidèrmiques de les larves dels cefalòpodes i per tècniques de proteòmica (2DE/MALDI-MS), de l'endolimfa de l'estatocist. Tots els estatocists d'individus adults de cefalòpodes exposats presentaven les mateixes lesions i aquests efectes eren més greus a mesura que passava el temps després de l'exposició als sons. Tots els animals exposats al soroll van mostrar lesions consistens amb trauma acústic massiu observat en altres espècies terrestres que havien estat exposades a intensitats molt més altes de so. Immediatament després de l'exposició, es van observar danys a la macula statica princeps (msp) i en l'epiteli sensorial de la crista. Els quinocilis de les cèl·lules ciliades desapareixien o es doblegaven i es tornaven flàccids. Un nombre important de cèl·lules ciliades mostraven els pols apicals sobresortint de l'epiteli sensorial, així com el trencament de les membranes plasmàtiques laterals, molt probablement com a resultat de l'extrusió de material citoplasmàtic. Les cèl·lules ciliades també van ser parcialment expulsades de l'epiteli sensorial deixant visibles forats esfèrics en el mateix. El contingut citoplasmàtic de les cèl·lules ciliades danyades va mostrar canvis obvis, com ara la presència de nombrosos vacúols i inclusions electrodenses que no es veien en els animals control. L'aparició d'aquestes lesions es va tornar gradualment més pronunciada en els individus analitzats després de 12, 24, 48, 72 i 96 hores. Es van validar curosament aquests resultats per mitjà de la comparació amb els animals control que van ser capturats, mantinguts i sacrificats de forma seqüencial seguint el mateix protocol que els individus exposats. La ultraestructura de l'estatocist va ser revisada i es va dur a terme un curós anàlisi comparatiu per tal d'avaluar les lesions provocades per l'exposició al soroll. Aquest estudi també presenta els resultats preliminars dels efectes del so en les línies epidèrmiques de cefalòpodes recent nascuts. Les lesions, consistens amb trauma acústic, eren idèntiques en les tres espècies que van ser exposades, però la seva evolució en el temps, en oposició amb el que es va observar en els estatocists, era diferent, cosa que suggereix que la grandària dels animals i la resposta metabòlica podria tenir influència en un possible procés de recuperació. L'avaluació dels efectes en l'endolimfa de l'estatocist per tècniques de proteòmica es va dur a terme només en Sepia officinalis. La presència de taques diferencials en els gels dels individus control i els sotmesos a exposició a so demostren que les lesions podrien estar relacionades amb un possible desequilibri fisiològic que tindria repercusions en els nivells proteics de l'endolimfa. Les lesions descrites aquí són noves pel que fa a la patologia dels cefalòpodes. Atès que els nivells de soroll de baixa freqüència a l'oceà estan augmentant (per exemple, a causa del transport, la indústria petrolera i les maniobres navals), que el paper dels cefalòpodes en els ecosistemes marins només ha començat a ser entès recentment, i que les dades bioacústiques fiables sobre els invertebrats són escasses, el present estudi i les investigacions futures aportaran una important contribució a l'ús sostenible del medi marí.

    The concrete is one of the most important construction materials. Its sustainability is determined by its durability, its low maintenance and its ability to be reused, recycled or recovered. Hence, the use of recycled aggregates produced from CDW (Construction and Demolition Wastes) can further contribute to the sustainability of the concretes, generating many environmental benefits and allowing the ideal closure of the life cycle of this material. However, the following aspects govern the sustainability of recycled aggregates used in concrete production: the recycled aggregate should be available at short distances, and the recycled concrete produced should not impact the environment and must be as durable as its equivalent conventional option. In Spain, the number of producers of recycled aggregate is high enough to make viable the use of this material. However, the supply of recycled aggregates suitable, according to national legislation, for production of concretes is quite low. The use of mixed recycled aggregates for production of concrete should be better valued since it is a very important step into the consolidations of this recycling sector in the country. Therefore, this study aims to analyze the sustainability of concretes made with recycled aggregates produced in Spain that do not meet the requirements of the current national legislation for concrete production. These investigations were conducted through the evaluation of the durability and the environmental impact, done by the leaching analysis. The evaluation of durability and environmental impact were done by an extensive experimental campaign with concretes produced using different proportions of coarse recycled aggregates (20%, 50% and 100%). Two types of recycled aggregates have been chosen: one mainly comprised of mortar, concrete and unbound aggregates elements, but with a significant amount of asphalt elements (aggregate AH), and another comprised of a large amount of ceramic elements (aggregate AC). Also, concretes made with 100% of conventional aggregate were produced as reference. The properties examined were: porosity, absorption, compressive strength, elastic modulus, drying shrinkage, mercury intrusion porosimetry, capillary absorption, carbonation, chloride penetration, and leaching of both the granular and the monolithic materials. The estimation and evaluation of the sustainability of the recycled concretes produced in this work has been done through indexes and indicators of the forecast lifespan and of the environmental impact created from mathematical models available in the literature and/or experimental results from this study. Finally, a new approach to the sustainable use of recycled concretes is advocated. The results obtained have been analyzed and compared, in order to validate the method developed and to define technical and environmental quality levels for recycled aggregates used in concretes in accordance with the needs, limitations and strengths of each situation.

    El hormigón es considerado uno de los materiales más importantes de la construcción civil. Su valor como material sostenible se determina por su durabilidad, necesidad de poco mantenimiento y capacidad de reutilizarse, reciclarse o recuperarse. En este sentido, el uso de árido reciclados provenientes de RCD puede contribuir aún más para la sostenibilidad de un hormigón, pues produce diversos beneficios ambientales y permite el cierre ideal de su ciclo productivo. La sostenibilidad de uso de áridos reciclados en la producción de hormigones, sin embargo, se establece por los siguientes aspectos: el árido reciclado debe estar disponible a cortas distancias, y el hormigón reciclado producido no puede generar impacto al medio y debe ser tan durable como su opción convencional equivalente. En España, la disponibilidad de productores de árido reciclado es lo suficientemente alta para viabilizar el uso de este material. En cambio, la oferta de áridos reciclados que se adecuen a las condiciones impuestas por la normativa española actual para la producción de hormigones es bastante reducida. El uso de áridos reciclados mixtos en la producción de hormigones debe ser valorado pues es un paso muy importante para consolidar este tipo de reciclaje en el país. A tal efecto, este estudio propone el análisis de la sostenibilidad de hormigones producidos con áridos reciclados españoles que no cumplen los requisitos impuestos por la normativa española actual para la producción de hormigones, a partir del análisis de su durabilidad e impacto ambiental. Se ha realizado una amplia campaña experimental donde se ha evaluado la durabilidad y el impacto ambiental por lixiviación de hormigones producidos con distintas proporciones de áridos reciclados gruesos (20%, 50% y 100%). Dos tipos de áridos reciclados han sido escogidos: uno compuesto mayoritariamente por elementos de mortero, hormigón y áridos no ligados, pero con una cantidad importante de elementos asfalticos (árido AH), y uno compuesto con una importante cantidad de elementos cerámicos (árido AC). Como referencia, se ha producido un hormigón hecho con 100% de árido convencional. Las propiedades analizadas han sido: porosidad, absorción, resistencia a compresión, módulo de elasticidad, retracción por secado, porosimetría de intrusión de mercurio, absorción capilar, carbonatación, penetración de cloruros, y lixiviación del material granular y del material monolítico. La evaluación y medida de la sostenibilidad de los hormigones reciclados producidos en este trabajo se ha realizado a través de índices y indicadores de previsión de vida útil y de impacto ambiental por lixiviación creados a partir de modelos matemáticos disponibles en la bibliografía y/o resultados obtenidos en la etapa experimental. Finalmente, se defiende un nuevo enfoque para el uso sostenible de hormigones reciclados. Se ha realizado el análisis y la comparación de los resultados obtenidos entre si, con el objetivo de validar el método desarrollado y de definir niveles de calidad técnicos y ambientales de uso de áridos reciclados en hormigón de acuerdo con las necesidades, deficiencias y calidades de cada situación.

    The most common challenges and obstacles encountered by construction organizations during the process of implementing and using environmental management systems are related to the inherent peculiarities of the construction sector. Several studies have shown that one of the issues involving the greatest level of uncertainty is the identification and assessment of environmental impacts. In order to improve the identification of the significance of environmental impacts of construction projects and sites, which will lead to greater efficiency and robustness in environmental management systems, this paper extends the systematic approach for identifying and assessing potential adverse environmental impacts at the pre-construction stage presented in Gangolells et al. (2009) by introducing the assessment of the concerns of interested parties. By considering concerns amongst internal and external interested parties, one can assess the significance of environmental impacts taking into account not only the severity of the impacts but also local perceptions and international challenges, thereby ensuring that the determination of the impacts’ significance is appropriate to the particular socioeconomic and biophysical environments surrounding construction sites. In order to quantitatively measure concerns among internal and external interested parties for each of the 37 environmental impacts related to a construction project, we developed corresponding indicators and assessment scales with the help of a panel of experts. A series of χ2 tests conducted over 76 new-start construction projects clearly revealed that the severity of environmental impacts is not correlated with the concerns of interested parties. The development of a formal quantitative method and the subsequent definition of a threshold make it possible to obtain advance knowledge of the significance – and, therefore, the acceptability – of each potential environmental impact for a particular construction project. A total score for each construction project alternative is also obtained, so the improved methodology provides a consistent basis for comparing construction companies and construction sites. Finally, two case studies are presented in order to demonstrate the benefits of the improved methodology.

    The WRF-ARW/HERMES-EMEP/CMAQ/BSC-DREAM8b modelling system provides high resolution air quality predictions for 48h in Europe –EU12- (12x12 km2, 1h), the Iberian Peninsula and Balearic Islands –IP4- (4x4 km2, 1h) and Canary Islands –CAN2- (2x2 km2, 1h) since July 2007, under the framework of the CALIOPE project (Baldasano et al., 2008; http://www.bsc.es/caliope/). A near real time evaluation system has been developed and it is on-line and in operation since January, 2009. Non validated near real time air quality data from more than 400 surface stations are compared to ground-concentration predictions in Spain. Seven ozonosondes are used to test the performance of the model in reproducing O3 vertical structures in Europe, Spain and Canary Islands. Additionally, OMI images are used to qualitatively assess the vertical column densities of NO2 predicted for Europe.

    Resum de la tesi (màxim 4000 caràcters. Si se supera aquest límit, el resum es tallarà automàticament al caràcter 4000) Molts dels problemes i obstacles que més freqüentment han d’encarar les empreses constructores durant el procés d’implementació i ús de sistemes integrats de gestió mediambiental i de seguretat i salut estan relacionats amb les peculiaritats pròpies del sector de la construcció. D’acord amb investigacions prèvies realitzades per diferents autors, una de les qüestions que tradicionalment comporta un major grau d’incertesa és la integració dels instruments de planificació i control, on s’inclouen els elements per a la identificació i l’avaluació dels impactes ambientals i dels riscos de seguretat i salut i l’aplicació de les subseqüents mesures de control. Aquesta tesi doctoral contribueix a la implementació i ús de sistemes integrats de gestió mediambiental i de seguretat i salut en empreses constructores amb un enfocament orientat al procés i emprant el risc com a factor d’integració. A nivell de projecte constructiu, aquesta recerca proposa una metodologia quantitativa per tal d’identificar i avaluar aquells riscos de salut i seguretat i impactes ambientals potencialment adversos que poden originar-se en obres residencials o d’altres tipologies similars durant les etapes pre-constructives. La metodologia desenvolupada facilita als dissenyadors la consideració de forma explícita dels impactes ambientals i la seguretat dels treballadors a l’obra durant el procés de disseny d’edificis residencials. Els dissenyadors poden comparar diferents alternatives de disseny i determinar, per a cada una de les solucions, el corresponent nivell d'impacte ambiental global així com el nivell de risc de seguretat i salut global, sense limitar el seu talent creatiu. La metodologia és especialment útil per a aquells dissenyadors menys experimentats que presenten una manca d’habilitats i coneixements per al reconeixement d’aspectes mediambientals i de riscos de seguretat i salut, ajudant-los a desenvolupar dissenys més òptims des d’aquestes perspectives. La metodologia també serveix com a eina d'avaluació per a que les empreses constructores puguin mesurar el comportament mediambiental i en termes de salut i de seguretat dels projectes constructius que duran a terme i les subseqüents activitats constructives, proporcionant una base consistent per a realitzar comparacions i per a l’establiment de futures etiquetes en termes mediambientals i de seguretat i salut entre diferents projectes de construcció i empreses constructores. La metodologia proposada també permet a les empreses constructores la optimització del seu comportament a l’obra en termes mediambientals i de salut i seguretat durant les etapes de planificació i preparació. La metodologia desenvolupada no només proporciona als dissenyadors un forma d’avaluar el comportament mediambiental i en termes de seguretat i salut dels seus dissenys residencials sinó que també ajuda a les empreses constructores a millorar el seu comportament mediambiental i en termes de seguretat i salut a l’obra. Una vegada s’ha assolit el disseny final, la metodologia subratlla aquells impactes ambientals i riscos de seguretat i salut que encara són significatius. Una millor identificació d'impactes ambientals i de riscos de seguretat i salut porta indubtablement a una gestió mediambiental i de seguretat in situ més exitosa. D’aquesta manera, es poden implementar a l’obra un conjunt d’instruccions de treball orientades a eliminar o reduir fins a un nivell acceptable els impactes ambientals i els riscos de seguretat i salut restants. Per tal de promoure el control operacional integrat a l’obra dels impactes ambientals i riscos de salut i seguretat, aquesta tesi doctoral proposa una aproximació basada en les ontologies. Entendre les relacions existents entre impactes ambientals, riscos de salut i seguretat, processos constructius i instruccions de treball proporciona una aproximació integrada que pot ajudar als contractistes a gestionar i controlar els impactes ambientals i els riscos de seguretat i salut relacionats amb el procés constructiu. Amb l’objectiu d’incrementar l'ús d'aquesta recerca, la metodologia desenvolupada s'ha implementat en un sistema web de gestió del coneixement i la informació. Per una banda, aquesta aplicació permet significativament reduir el temps dedicat a l'avaluació de cada projecte de construcció. D'altra banda, la formalització i visualització de l’aproximació basada en ontologies que s’ha desenvolupat durant la tesi confereix una guia per als contractistes en la gestió de moltes de les incidències mediambientals i de seguretat i salut que poden tenir lloc a les obres de construcció. Finalment, aquesta tesi doctoral documenta la verificació i la validació de la metodologia desenvolupada i de la corresponent eina d’implementació. La tesi doctoral conclou subratllant les principals contribucions d'aquesta investigació. Aquells temes que sobrepassen l’abast d’aquesta tesi són comentats i proposats com a futurs treballs.

    Most common challenges and obstacles encountered by construction organizations during the implementation process and use of integrated environmental and health and safety management systems are related to the inherent peculiarities of the construction sector. According to several research authors, one of the issues involving a higher level of uncertainty is the integration of planning and control instruments, including elements for identifying and assessing environmental impacts and health and safety risks and implementing subsequent necessary control measures. This dissertation contributes to the implementation of environmental and health and safety management systems in construction companies by proposing a process-oriented approach and using risk as an integrating factor. At a project level, this research proposes a quantitative methodology for dealing with potential adverse environmental impacts and health and safety risks during the pre-construction stages of residential buildings and other similar typologies. The strength of this methodology lies in the fact that it helps designers to explicitly consider on-site environmental impacts and construction worker safety during the design process. Designers can compare several design alternatives during the design phase and determine corresponding overall environmental impact level and overall safety risk level of a construction project without their creative talents being restricted. The methodology is especially worthwhile for those less-experienced designers who lack the skills and knowledge required to recognize environmental aspects and safety hazards, developing optimal designs. The methodology also serves as an assessment tool for construction companies to measure the environmental and health and safety performance of construction projects and its subsequent construction activities, providing a consistent basis for comparisons, future labelling and environmental and safety benchmarking among construction projects and construction companies. The suggested methodology also allows construction companies to optimize its on-site performance in the environmental and the health and safety domains during the planning and preparation stages. The developed methodology not only provides designers with a risk-analysis-based way of evaluating the environmental and safety-related performance of their residential construction designs, but also helps construction companies improve their on-site environmental and safety performance. Once a final design is reached, the methodology highlights the significant remaining environmental impacts and health and safety risks. Improved levels of environmental impacts and safety risks identification undoubtedly lead to successful on-site environmental and safety management. A range of measures can then be implemented at the construction site to eliminate the remaining impacts and risks or reduce them to an acceptable level. In order to promote the integrated operational control of on-site environmental impacts and health and safety risks, this research proposes an ontology-based approach. Understanding relationships between environmental impacts, health and safety risks, construction processes and work instructions provides an integrated approach to help contractors managing and controlling environmental impacts and health and safety risks related to the construction process. In order to increase the usability of this research, the developed methodology has been implemented in a web-based information-and knowledge-management system. On one hand, this application allows significantly reducing the time devoted to the assessment of each construction project. On the other hand, formalizing and visualizing the developed ontology-based approach offers guidance to contractors on the integrated management of many of the environmental and health and safety incidences at the construction site. Finally, this dissertation documents the verification and validation of the developed methodology and corresponding web-based implementation tool. The dissertation concludes by outlining the main contributions of this research. Those subjects that exceed this dissertation scope are commented and proposed as future work.

    The present contribution describes a thorough quantitative evaluation study performed for a reference year (2004). The CALIOPE modelling system is configured with 38 vertical layers reaching up to 50 hPa for the meteorological core. Atmospheric initial and boundary conditions are obtained from the NCEP final analysis data. The vertical resolution of the CMAQ chemistry-transport model for gas-phase and aerosols has been increased from 8 to 15 layers in order to simulate vertical exchanges more accurately. Gas phase boundary conditions are provided by the LMDz-INCA2 global climate-chemistry model (see Hauglustaine et al., 2004). The DREAM model simulates long-range transport of mineral dust over the domains under study. For the European simulation, emissions are disaggregated from the EMEP expert emission inventory for 2004 to the utilized resolution using the criteria implemented in the HERMES emission model (Baldasano et al., 2008b). The HERMES model system, using a bottom-up approach, was adopted to estimate emissions for the Iberian Peninsula simulation at 4 km horizontal resolution, every hour. In order to evaluate the performances of the CALIOPE system, model simulations were compared with ground-based measurements from the EMEP and Spanish air quality networks. For the European domain, 45 stations have been used to evaluate NO2, 60 for O3, 39 for SO2, 25 for PM10 and 16 for PM2.5. On the other hand, the Iberian Peninsula domain has been evaluated against 75 NO2 stations, 84 O3 stations, 69 for SO2, and 46 for PM10. Such large number of observations allows us to provide a detailed discussion of the model skills over quite different geographical locations and meteorological situations.

    El Análisis del Ciclo de Vida (ACV) es una herramienta metodológica que determina los potenciales impactos ambientales asociados con un producto o servicio, desde la extracción de la materia prima hasta su disposición final. El objetivo de este estudio es evaluar los potenciales impactos ambientales asociados a cada uno de los proceso del sistema de gestión de residuos sólidos de la Ciudad de México, mediante la aplicación del software TEAM, se evaluó las siguientes categorías de impacto: acidificación, disminución del ozono estratosférico, eutrofización, efecto invernadero (directo, 100 años), formación de foto-oxidantes, toxicidad terrestre, efectos carcinogénicos y efectos respiratorios. Los resultados sugieren que el sistema de manejo de residuos sólidos de la Ciudad de México presenta impactos relevantes en los procesos de vertedero controlado, vertederos no controlados y reciclado de vidrio; el proceso de fabricación de compost se presenta como una opción favorable debido a que no presenta impactos ambientales significativos. El ACV realizado sugiere la siguiente jerarquía de tratamientos de residuos municipales: fabricación de compost, incineración, reciclaje y vertedero controlado. La peor alternativa es el vertido no controlado de residuos debido a que se trata de superficies donde los residuos son depositados de forma clandestina y no cuentan con ningún tipo de control de la contaminación.

    La clase expositiva remonta al siglo XII como eje básico del modelo de aprendizaje superior. Los papeles y funciones repartidos eran muy simples: el maestro transmitía sus conocimientos-sabiduría al discípulo-estudiante, y así ha sido a lo largo de los últimos nueve siglos. Dicho planteamiento ha podido funcionar de forma efectiva mientras que el acceso a los estudios superiores era limitado, pero con el acceso creciente y masivo no funciona. Uno de los factores que provocan este fracaso es la ratio alumnos-profesor que ha venido incrementándose de forma espectacular. En este marco aparece la semi-presencialidad, que nos ayudará a optimizar los recursos para un número mayor de estudiantes, y las nuevas tecnologías (Internet entre otros), que nos facilitarán la difusión de material didáctico y posibilitan nuevas interacciones entre docentes y alumnos. Por ello y para resolver una necesidad planteada por el alumno, de tener la presencia del profesor para la resolución de dudas (tutorías), en este trabajo exponemos la solución propuesta por el Departamento de Proyectos de la UPC en la Escuela de Terrassa, que consiste en poder hacer videoconferencias con el profesor, para la resolución de las dudas.
