▼ Aquesta tesi doctoral de la Universitat de València analitza l’evolució del periodisme ambiental des de la premsa generalista espanyola –durant les dues dècades prèvies a l’arribada al segle XXI- fins les edicions digitals dels diaris europeus de referència i de les revistes deganes de natura dels quatre països objecte d’estudi: la Gran Bretanya, França, Itàlia i Espanya. Ho fa, a més, en un moment històric clau per a la indústria periodítica perquè hi conclueixen dos importants factors. Per un costat, la transició del model en paper convencional al paradigma digital i, per un altre, la crisi econòmica iniciada en 2008, la qual va tindre una gran influència en el recursos humans de les plantilles de les redaccions de mitjans escrits. El treball de recerca té dues parts diferenciades. La primera d’elles se centra en l’àmbit espanyol i en suport paper, després d’haver fet un repàs de la coneguda com a segona eclosió de la divulgació de la natura durant el segle XIX. Considerem que aquest moviment constitueix un dels gèrmens del periodisme ambiental, juntament amb altres factors posteriors com ara els signes evidents del deteriorament de l’entorn, les primeres alertes científiques i d’organismes internacionals i, especialment, la lluita de les organitzacions ecologistes. D’aquesta manera, per començar, s’estudia l’evolució del periodisme ambiental durant dues dècades (1984-2004) a través de les pàgines de dos diaris d’àmbit estatal, El País i La Vanguardia, i un d’àmbit autonòmic, Levante-El Mercantil Valenciano i de cinc suplements verds publicats per capçaleres diàries de distribució estatal: ABC Natural, Tierra, Natura, Verde y Ciencia y Tecnología. La segona part de la tesi doctoral de Maria Josep Picó i Garcés aprofundeix en el periodisme ambiental en l’àmbit europeu i, atesa la ràpida influència d’Internet en la producció, la distribució i el consum de la informació, obrim en nostre camp d’investigació a l’entorn digital, tant d’edicions digitals de capçaleres com de revistes de natura. En aquest apartat podem trobar diversos focus d’atenció. Per exemple, l’estudi en profunditat, mitjançant metodologies quantitatives i qualitatives, de les estratègies digitals de les revistes de natura deganes a Europa: BBC Wildlife, Terre Sauvage, Oasis i Quercus. A més a més, aquesta recerca analitza l’aparició i evolució dels blogs periodístics ambientals a les edicions digitals de la premsa europea com a nou gènere periodístic. Els blogs són elaborats per diversos tipus de perfil d’autors, entre els quals destaquen els professionals freelance, tant periodistes com científics i ambientalistes. Paral·lelament, també s’estudia el lideratge dels periodistes ambientals de diaris i revistes de natura en les xarxes socials, en concret, en Twitter, la més periodística de totes elles. Un dels seus objectius d’aquest treball és reivindicar el periodisme ambiental de qualitat i rigorós en l’entorn digital per la seua rellevància econòmica, política social i cultural. I, a més, amb incidència en la qualitat de vida de la ciutadania… Advisors/Committee Members: Domínguez, Martí, Departament de Teoria dels Llenguatges i Ciències de la Comunicació.

▼ Multiphase Reactive Transport (MPRT) modelling involves simulating flow of fluid phases, transport of species and energy, and reactions between species within the same or different phases. Reactive transport codes decouple phase flow calculations from reactive transport. This approach has been successfully applied to a wide range of MPRT problems, but it may be unsuitable for problems like the chemical evolution of unsaturated tailings or the salinization of soils, where concentrated solutions or extremely dry conditions are be reached. The amount of liquid water in these cases can be so small that both vapor and water in hydrated minerals can be significant for the water balance. Wissmeier and Barry (2008) developed a code which couples chemical sink-sources and water flow, but only for cases where transport is limited to unsaturated liquid phase. However, under these extreme conditions gas transport becomes important and water activity, which controls vapor pressure, is affected by capillary and salinity effects. Moreover, certain mineral paragenesis (the ones that produce invariant points) fix water activity, causing the geochemistry to control vapor pressure, which is a key gas flow variable. Thus, a fully coupled solution of phase fluxes and reactive transport is required for these conditions. The main objective of this thesis is to develop a general MPRT code capable of representing the effect of geochemistry on flow and transport for concentrated solutions under extreme dry conditions. As a secondary objective, the behavior of some cases under such conditions is studied. Different aspects of this code and different cases are discussed through the chapters of this thesis. First, coupling of salinity and vapor pressure (and thus evaporation rate) is discussed, and a method for computing the evolution of high salinity systems is presented. Special emphasis is placed on the treatment of invariant points, that are sets of minerals that fix water activity. The method is applied to a natural MgSO4-rich brine evaporation experiment and to a simplified model of a perennial saline playa lake. The results indicate that mineral paragenesis can have a considerable influence on the evolution of shallow brine systems by fixing chemical composition for a significant portion of time. Second, the evolution of concentrated solution in porous media is discussed. In this scenario evaporation is affected not only by salinity but also by capillary effects. Also transport is considered. A generalized compositional formulation for MPRT, which considers coupling effects between geochemical and hydrodynamic process problems, is presented. Some aspects related to its numerical solution are discussed as well. The advantages of the formulation are illustrated by simulating the effect of mineral dehydration on the hydrodynamic processes in a gypsum column that reaches extremely dry conditions. The results indicate this significantly affects the evolution of the system. Finally, implementation of the… Advisors/Committee Members: [email protected] (authoremail), false (authoremailshow), Saaltink, Maarten W.

▼ The development of airborne pollen and fungal spores models aims among others, to evaluate and predict their concentrations and/or seasonal dynamics; to establish, develop and/or validate atmospheric transport models; and/or to correlate concentrations with impacts or changes detected in environmental processes. The general objective of this thesis was to develop different statistical models to study the spatial-temporal variation of the main airborne pollen and fungal spores in Catalonia. In the first chapter we analyzed the predictive and dispersion models present in the literature, concluding that the models based on observations (OBM) have been frequently used to predict future concentrations, the models based on phenology (PHM) to characterize the flowering period, and a range of other models (Other models) to establish spatial estimates in unmonitored areas. PHM are more diverse, easier to apply and they use a smaller number of independent variables than OBM. The dispersion models (other models) are classified according to the direction of the modeling (Forward or Backward) and present a smaller number of applications due to their high technical-scientific requirements, being their greatest limitation the establishment of the flow and the emission source. In the second chapter, we validated a gamma distribution model to characterize annual series of pollen and spores data and to establish the few of them showing representative patterns. From the results we concluded that the α parameter of the model changed reasonably from year to year, depending on the meteorological conditions, with good inter-annual and spatial stability and allowing to establish a generic classification of the airborne particles studied in five categories for pollen and five for fungal spores. This classification showed a strong relation of α parameter with the ecological distribution of the plant (potential and/or ornamental) in the case of the pollen taxa and with the land use and/or the bioclimate of the zone in the case of the fungal spores. The classification established will allow reducing the number of taxa with which to develop new prediction models in the third chapter we selected 12 taxa (six pollen and six fungal) and developed predictive models based on concentration thresholds instead of on concentrations. We evaluated the predictive potential of of logistic regression models and regression tree models at four concentration thresholds (low, medium, high and very high). The two models showed similar results regarding the relationship and/or influence of the meteorological parameters in the different thresholds, presenting highly satisfactory values on sensitivity and specificity during the validation. However, we observed that the logistic regression models gave a greater precision (sensitivity) in establishing the exceedance of a concentration threshold and therefore that they are the most suitable for future estimates. Finally, in chapter 4 it was undertaken a trend analysis with the… Advisors/Committee Members: Universitat Autònoma de Barcelona.

▼ "El Morado Natural Monument (Central Chilean Andes). Biophysical medium, landscape and behavior proposal." TEXT: This Phd thesis deals with the geographical study of the Morales stream basin, tributary of the Volcán River, in the Chilean central Andes. For that purpose it analyses the biophysical medium; describes, analyses and classifies the landscape, it puts forward a series of proposals for its better and adequate management. It is about a base research that provides interesting data related to the valley's natural system classified as protected figure by the Chilean government, managed by CONAF, type of landscape that characterizes it and recommendations for its use and safeguard of its patrimonial values. (Natural and socio economical medium). From the biophysical medium perspective it must be said that this region possesses a huge interest because it is a recent melted glacier where we still can see an ice cap (San Francisco glacier). This fact turns it into an specific mountainous area where glaciers and periglaciers endure and take turns according to the season, fact that guides the dynamism and evolution of their ecosystem. In that sense, what can be highlighted is the spread of morphogenic processes, clastos production and mass movements, all that results on a generalized instability of hillsides due to steep slopes.This cold weather conditions converge at the development of an incipient ground, mainly because of its capacity to use VIII and on the presence of a vegetation cover in an open position and herbaceous or shrub-like size. However these ecological conditions are not the same in the lowest sections of the valley where Baños Morales village can be found. It is an urban center which shows a diverse landscape due to nice weather conditions and an introduced wooded area. The valley itself is a high value patrimony medium, particularly in its biophysical and socio cultural context plus thermal water outbursts due to volcanic activity in the area. That fact gives the place the quality of "protected area" because there are vast ecosystems that house relic vegetal species and material form old colonization, besides the fact of being a significant high scientific enclave to do research and also to follow up the melting process of ice caps mass glaciers (San Francisco). These circumstances require actions towards the landscape and so, it is necessary to check former laws put forward by CONAF and, at the same time, to assume new programs by the administration that will lead towards the preserving of patrimonial values and beauty of the valley.

▼ Slaughterhouse wastes are interesting for the anaerobic digestion process regarding its high biogas production potential and because the current legal scenario promotes renewable energy production. The high lipid and protein content of those residues limit its treatment due to inhibitory processes, in particular the inhibition caused by long chain fatty acids (LCFA). The objective of the present disertation is to obtain a deeper insight on the LCFA inhibition process, the microorganism adaptation ability and the prevention/recovery of inhibitory phenomena. In a preliminary approach, organic wastes generated in slaughterhouses are characterized, by studying the anaerobic biodegradability of waste mixtures containing diferents lipid/proteins concentrations. Anaerobic batch tests are performed at increasing substrate concentrations by sequential pulse feeding. From those experiments, the fast hydrolysis-acidogenesis of proteins is verified, being the lipids and LCFA degradation the main limiting step of the overall anaerobic process. Despite this limitation, the system is able to recover up to a higher methane production rate after each applied pulse. In order to elucidate on the mechanisms of the recovery process, several strategies to recover LCFA inhibited reactors are tested. The increase of the biomass/LCFA ratio and the adition of bentonite to reduce the biodisponibility or the adsorption of LCFA over microbial cell walls, are found to be effective approaches in the operation of fullscale biogas plants. The obtained results reinforce the hypothesis of the adsorptive nature of the LCFA inhibition, and that the recovery process can be followed as an increase in the microbial activity. The nature of the reported microbial activity improvement after subsequent sytem inhibition is characterized by three different techniques: 1) the study of specific microbial activities on different model substrates, 2) the application of molecular biology tools to monitor the microbial population structure and, 3) the development of kinetic expressions of the LCFA inhibition phenomena, based on the adsorption process, within the framework of ADM1 model of the International Water Association. The combined analysis of those confirmed that inhibition and adaptation phenomena are explained by a specific microbial growth, including adsorption in the metabolic LCFA inhibition process. The adsorption-inhibition process is evaluated in detail by determining LCFA adsorption isotherms on granular sludge, LCFA toxicity test, and fluorescence microscopy techniques. This multidisciplinary approach results in the definition of an inhibition preventing strategy based on the introduction of competitive adsorbents, and on stating the importance of palmitate during ß-oxidation of LCFA. This study contributes to the understanding of slaughterhouse wastes anaerobic treatment, the LCFA inhibition process, and the biomass adaptation phenomena. The physical adsorption process has been directly related with the LCFA metabolic inhibition, and a new… Advisors/Committee Members: Fernández García, Belén (codirector), Flotats i Ripoll, Xavier (codirector).

▼ This work tries to define the framework that the Spanish Constitution builds to allow the development of environmental policies. The environmental protection is considered as one of the main elements of the constitutional economic model, which redefine the relationships between the human beings and their environment through the regulation of productive processes and exploitation of natural resources. According to this point of view, the environmental protection in the modern law systems is related to a need to establish rules for the economic activity of industrial societies to stop the degradation of the living conditions defined by the structure of the physical environment around the human being. From this point of departure, the work is divided in three main parts: context, concept and constitutional development. The first task to do is to show that the appearance of legal norms about the environment is a relatively new phenomenon which begins with the take of conscience of the magnitude of the effects of human activity in the natural world. This happens since the Second World War and, more intensely, since the 60's. With that historical contextualization we try to locate the appearance of environmental law in the framework of the crisis of ideological presuppositions of Modernity about the relationship between the human being and the nature, as developed in the industrial and technological culture of the last centuries. Second we define the constitutional concept of environment "adequate to development of the person" as the normative configuration of the physical global space according to the teleological orientation defined by the Constitution. Therefore we exclude the restrictive approaches to the legal concept of environment because we consider that they do not fit in the interpretation of the constitutional text. For this reason, despite the article 45.1 of the Spanish Constitution is formally the recognition of a right, we consider that it is primarily the recognition of a power of the government, because, in order to protect the environment, we need previously a normative definition of the protected form of it, which cannot depend on the exercise of individual rights. In fact, this constitutional norm gives the government some kind of authorisation to put limits in the exercise of certain rights as the property. Anyway, despite the Constitution allows several possible solutions in environmental politics, we defend that it is not possible any environmental policy within the framework defined by the fundamental norm. Therefore, in the cases in which the normative activity of the Parliament does not fit with the constitutional mandate to protect an environment "adequate to development of the person", it will be possible the declaration of inconstitutionality by the Constitutional Court. The possibility of control the legislator is a sufficient argument to justify too the intervention of the courts in the control of the government. We must situate in this framework the exercise of the individual… Advisors/Committee Members: [email protected] (authoremail), true (authoremailshow), Vernet i Llobet, Jaume (director).

▼ In recent years chemical pollution research has focused on the study of pollutants that pose a risk to human and/or environmental health due to their toxicity, high persistence in environment and bioaccumulatioin properties. One issue with these substances, including the halogenated flame retardants (HFRs) is that they are continually introduced into the environment from industrial production, use in various consumer products, and releases during recycling and/or disposal. In recent decades, studies on HFRs, particularly on polybrominatedbiphenyl ethers (PBDEs), have increased worldwide, mainly due to their persistence and presence in various matrices. Currently, two of the PBDEs technical products (PentaPBDE and OctaBDE) are being eliminated or have been banned in North America and Europe, while DecaBDE has been banned in Europe. In U.S. DecaBDE production, import and sale will be discontinued in late 2013. After consumption and production decline of PBDEs, other flame retardants are used increasingly to replace them. The Environmental Forum of the Bromine Science (BSEF) of 2001 indicated that the use of HFRs was led by tetrabromobisphenol A (TBBPA) (59%), and that hexabromocyclododecane (HBCD) also showed an increase in use worldwide. Therefore, it is important to develop evaluation studies of environmental risk for these substances. This requires detailed information about their presence, fate and transformation in the environment, in order to evaluate the possible exposure of humans and other organisms to these compounds. To achieve this information, the first essential step is to have reliable analytical methods sensitive enough to determine environmental levels. At the beginning of my thesis “Analysis of emerging halogenated flame retardants and its impact on the environment and humans” in 2006, research groups involved in the issue of HFRs started with the optimization of methods for analysis of hexabromocyclododecane (HBCD) in environmental matrices. Once the scientific community has provided sufficient data on presence, fate, behavior and toxicity of these compounds, we can evaluate whether it is advisable to continue using these HFRs or if, on the contrary, these new emerging HFRs are also detrimental enough to environmental and/or human health that they should also be banned, as were their PBDEs predecessors.

▼ Los organismos han desarrollado a lo largo de la evolución una amplia gama de estrategias para mantener un estado homeostático interno a pesar de ciertas fluctuaciones ambientales tales como la disponibilidad de nutrientes. En los últimos años, p53 ha surgido como un importante regulador de varias rutas metabólicas, capaz de desencadenar una respuesta celular adaptativa a fluctuaciones en la disponibilidad de nutrientes, una función que puede contribuir no sólo a la capacidad supresora de tumores de p53, sino también a otras funciones más fisiológicas no asociadas con el cáncer. El homólogo de Drosophila de p53 (Dp53) comparte una identidad significativa en secuencia de aminoácidos con p53 de mamíferos, capaz de promover funciones similares en respuesta a varios tipos de estrés. Los resultados presentados en esta tesis revelan un papel fundamental de Dp53 en la adaptación del organismo a la privación de nutrientes. Dp53 se requiere específicamente en el ‘cuerpo graso’ de Drosophila, un análogo funcional del hígado y el tejido adiposo de los vertebrados. La reducción de los niveles de actividad de Dp53 específicamente en este tejido acelera el consumo de las principales reservas de energía, reduce los niveles de azúcares en el animal, y compromete la supervivencia del organismo en ayuno. El impacto de Dp53 en el balance de energía es independiente a la regulación de las hormonas involucradas en el mantenimiento de la homeostasis metabólica y de las enzimas metabólicas implicadas en la movilización de los recursos energéticos. Desvelamos un papel autónomo-celular de Dp53 en la modulación de los cambios metabólicos que padecen las células del ‘cuerpo graso’ ante la privación de nutrientes. También identificamos el mecanismo molecular por el cual Dp53 se activa en condiciones de escasez nutricional en las células del ‘cuerpo graso’. Demostramos que los microRNAs (miRNAs) son capaces de regular la expresión dp53 e identificamos miR-305 como principal regulador. En una situación de privación de nutrientes, los niveles de expresión de varios elementos implicados en la biogénesis de los miRNAs se ven altamente reducidos, lo cual conlleva a la liberación de la represión mediada por miR-305, activando así Dp53 y contribuyendo a la resistencia del organismo frente a una situación de carencia nutricional.

▼ This thesis analyses the configuration of the ecological movement in Catalonia, its claiming and mobilizing activity and its importance as a critical school of thought maker of the capitalist economic development, source of serious environmental problems. It has been taken into account the main scientific and philosophical theories that raise the need for a global view of nature, as well as the contribution of social movements, ecological organizations, the agreements emerged from the main summits and international agreements on the environment, as well as environmental policies posed by the European Union and Catalan public administrations with responsibilities in the environmental field (Generalitat de Catalunya, county councils, district councils, city councils...). The model of growth characteristic of capitalism has formed an anthropocentric mentality in relation with nature, which has led to an unsustainable economic, political and social system in terms of environment having caused in Catalonia serious problems of pollution and great social and territorial inequalities. From the ecological movement several alternative proposals have been raised to this model of growth, collecting reflections that, from the scientific field, deepen the need to develop comprehensive actions against the global ecological crisis in relation to the concepts of Biosphere, geographical landscape, Ecosystem, Geographic environment, Gaia and Biological regionalism. These reflections have also been made from social movements, which provide an alternative model of society based on the principles of an ecological economy, a new model of consumption, structural changes to the model of occupation, new mechanisms of sharing out work and wealth redistribution, promotion of participatory democracy, environmental education, an alternative energy system, ecological agriculture, etc.. The formation of the ecological movement in Catalonia is the result of contributions from anarchism, movement for peace, feminism, scientific and geographical thinking and social movements which have been able to mobilize the Catalan society to solve these serious environmental problems it faces, raising a change of economic, social and political model, based on the values of cooperation and mutual aid. The ecological movement in Catalonia has had a key influence in the development of environmental public policies by incorporating some of its principles: the need for a global approach of environmental problems through the integration of policies developed by the European Union in the field of environment, as well as the guidelines of the major summits and international agreements; the incorporation of citizen participation mechanisms in environmental decision-making; the application of corrective measures for the dysfunctions caused in the environment; and the integration of social, political and economic factors on environment policies. However, the public policies developed in Catalonia have not incorporated effectively one of the main issues arisen from the… Advisors/Committee Members: [email protected] (authoremail), true (authoremailshow), Mendizàbal, Enric (director), true (authorsendemail).

▼ Els principals objectius d’aquesta tesi han estat els de (a) determinar els efectes de la fertilització de nitrogen (N) i fòsfor (P) sobre el creixement dels grups algals del perífiton i del fitoplàncton, i (b) avaluar la influència d’alguns processos reguladors (p.ex. contingut de N:P, contingut de clorofil·la per biovolum) involucrats en les respostes del creixement. S’ha seguit una aproximació experimental de camp basada en la utilització de substrats difusors de nutrients en el cas del perífiton (Capítol 1), i en l’addició de nutrients a mesocosms en el cas del fitoplàncton (Capítol 2 i 3). En el primer capítol es va avaluar la influència dels factors que controlen la colonització del perífiton per part de les diatomees i dels cloròfits. La renovació de l’aigua i l’estat tròfic (DOC) van tenir un efecte positiu en la colonització algal. L’alta disponibilitat de N en relació a P va tendir a afavorir els cloròfits per sobre de les diatomees. Les addicions de nutrients (sobretot de N) van resultar perjudicials pel creixement de les diatomees en molts casos, mentre que els cloròfits van tolerar millor aquestes altes concentracions. En el segon capítol es van observar diferents pautes de resposta de la producció, l’estructura de la comunitat i la composició C:N:P del seston a diferents enriquiments amb P. La producció primària va augmentar considerablement a addicions baixes i mitjanes de P, mentre que les proporcions C:N:P del seston només van canviar de forma marcada -dirigint-se cap a “Redfield”- a altes addicions de P. Les condicions d’excés de N van reduir el creixement del fitoplàncton però no van afectar les proporcions C:N:P. Finalment es van avaluar les relacions entre disponibilitat de nutrients, creixement i contingut de clorofil·la per biovolum en el fitoplàncton. Les diatomees i els cloròfits van demostrar tenir les capacitats de creixement més altes, i això podria estar associat amb la seva habilitat d’incrementar el contingut de clorofil·la quan la disponibilitat de nutrients augmenta. Les crisofícies i les dinofícies van assolir les màximes taxes de creixement a concentracions de P comparativament baixes, indicant que estarien més ben adaptades a baixes disponibilitats de nutrients.

▼ Para comprender cómo funciona la dinámica de la hojarasca en arroyos, la presente tesis pretende examinar (a) cómo las características hidro-morfológicas del lecho del arroyo pueden influir en la retención, distribución espacial, fragmentación física y descomposición de la hojarasca. Además, también examinamos (b) la interacción entre el procesamiento de hojarasca y la dinámica del carbono orgánico disuelto y nitrógeno inorgánico disuelto del arroyo y cómo varía dependiendo de las especies de hojarasca consideradas. La presente tesis revela que la heterogeneidad de la velocidad del agua dentro de un tramo es un factor que controla diferentes aspectos de la dinámica de hojarasca en arroyos, ya que no solo influye en la fracción de hojarasca retenida, sino también en cómo estas entradas se distribuyen espacialmente y se procesan en los arroyos. Por lo tanto, indicamos que la relevancia de las entradas de hojarasca como fuente de materia orgánica para las comunidades del arroyo puede estar sujeta a las características hidro-morfológicas de dicho ecosistema, ya que determinan la heterogeneidad espacial de la velocidad del agua dentro del mismo. Además, sugerimos que la calidad de la hojarasca influye en las propiedades químicas y estructurales de los lixiviados de hojarasca y también cómo estos lixiviados son utilizados por los microorganismos del arroyo. La calidad de la hojarasca también puede dictar las demandas microbianas de C y N disuelto de la columna de agua. Finalmente, sugerimos que la influencia de las concentraciones de nutrientes del arroyo en la descomposición de la hojarasca puede estar sujeta a la calidad de la hojarasca. Teniendo en cuenta todos nuestros resultados, sugerimos que la composición del bosque de ribera, que determina la calidad de las entradas de hojarasca, puede controlar el vínculo entre el procesamiento de la hojarasca y la dinámica de solutos C y N del arroyo. Sin embargo, la heterogeneidad de la velocidad del agua puede ser el factor más relevante para determinar la importancia de la hojarasca en las corrientes, ya que puede controlar la probabilidad de que las hojas queden retenidas en el arroyo o se exporten aguas abajo, perdiéndose como fuente de materia y energía.

▼ [cat] En aquesta tesi s'han desenvolupat diferents dispositius emprant tecnologies d'impressió 3D, o eines de control numèric, les quals s'han integrat en sistemes automàtics d'anàlisi que utilitzen tècniques d'anàlisi per injecció en flux. Els dos primers treballs descriuen un dispositiu realitzat per mitjà d'eines de control numèric, que permet l'estudi de la lixiviació dinàmica de 226Ra, U i Th en residus i mostres ambientals (fosfoyeso, terra i sediment). El dispositiu es va integrar en dos sistemes automàtics en flux, que combinen les tècniques Lab-On-Valve i l'anàlisi per injecció en flux multixeringa (LOV-MSFIA). Els sistemes permeten realitzar la lixiviació, extracció i preconcentració en línia dels radionúclids estudiats. En ambdós treballs es realitza una detecció posterior fora de línia, que per al 226Ra es porta a terme en un comptador proporcional de baix fons, i per l'U i el Th en un ICP-MS. Els sistemes proposats van permetre estudiar el procés de lixiviació des d'un nou enfocament, ja que es basen en una lixiviació dinàmica amb renovació constant de l'extractant, que imita el procés de lixiviació natural. El tercer treball consta de dues parts. A la primera part es descriu l'ús de la tècnica d'impressió en 3D per estereolitografia, que permet la impressió en tres dimensions d'estructures complexes amb alta precisió. El dispositiu 3D fabricat va ser recobert amb la resina TEVA, per a l'extracció / preconcentració selectiva d'U(VI) en mostres ambientals. A la segona part, es presenta la integració d'aquest dispositiu 3D en un sistema en flux automàtic, amb posterior detecció mitjançant un ICP-MS. El mètode proposat utilitza la tècnica d'anàlisi per injecció seqüencial (SIA). Els resultats obtinguts, tant en els paràmetres analítics com en l'anàlisi de mostres, han estat satisfactoris. En aquest treball es proposa un mètode simple per a l'extracció selectiva d'U en mostres ambientals sense el requeriment d'un pretractament. El quart treball presenta un sistema completament automatitzat, que permet l'extracció i detecció en línia de 90Sr. El sistema de detecció va ser desenvolupat en col•laboració amb l'empresa iC-Màlaga i utilitza un comptador de centelleig líquid basat en tubs fotomultiplicadors. El sistema automàtic combina les tècniques d'anàlisi en flux LOV i MSFIA, i integra dos dispositius impresos en 3D, una caixa fosca per aïllar la cel•la de detecció de la llum ambiental i un mesclador per aconseguir una barreja homogènia de l'eluat i el líquid de centelleig. El prototip de sensor construït permet dur a terme tots els passos del protocol analític, incloent-hi l'extracció i preconcentració de 90Sr, la barreja de l'eluat amb el líquid de centelleig i el comptatge en línia de les emissions beta.

▼ In recent decades, the relationship between humankind and the environment has grown stronger. Indeed, over time the concern and active participation of citizens in ecological and environmental issues is becoming more frequent worldwise, and more recently the link from those issues to social and economic issues is leading to a new paradigm called sustainability. Accordingly, through this doctoral thesis the origin, evolution, and feasibility to operativize sustainability in the construction sector is studied. The meaning of sustainability is different among the earth´s nations; nevertheless, there are some important common themes such as a concern for the environment and its resource limits and sink limits, and a concern for both inter and intrageneration equity. Thus, those common aspects had brought about that most sustainability definitions appeal to the goodwill so sufficient resources for future generations be left, in order for they having a quality of life similar to ours. In this academic work the criteria from the main United Nations documents about sustainability has been adopted. A benchmark may thus be established by setting out the sustainability principles in order to approach them to the construction sector, dealing with new buildings specifically. To approach sustainability principles for the construction sector, conceptualization and pragmatic (quite different) aspects must to be addressed in order to join them in a common task, taking into account the number of theoretical and empirical themes to deal with. The research and the thesis writing were organized on five linked parts, which make up thirteen chapters. The first part (chapters I, II, and III) is the core of the thesis, because the methodology and the bottom line are set out in those chapters, and also because the origin, evolution, and the sustainable development debate are exposed. The second part (chapters IV and V) relates to the technical items for sustainability such as Thermodynamics, the entropy law and the environment; and then these concepts and their relationship with energy and matter. It is to be stressed that these last items are the main raw materials for the construction sector. This second part also contains tools and techniques to support sustainability, e.g. life-cycle assessment, multtiatribute decision analysis, the environmental impact assessment, sustainability indicators, ISO 14 000 standards, and life-cycle costs for building materials. The previous parts provide enough knowledge and information for conducting a proposal to a more socially responsible construction sector through, the so called, sustainable construction. That is the core subject of the thesis, for which in the third part (chapters VI, VII, VIII and IX) the fundamental premises for sustainable construction are established, those premises stress the adverse environmental impacts from buildings to be tackled by sustainability principles related to resources conservation, minimizing waste through re-use and recycling… Advisors/Committee Members: Universitat Politècnica de Catalunya.

▼ This doctoral research approaches, from a perspective of the environmental psychology, the relationships that may exist between the level of the environmental management and certification of universities, and their student´s pro-environmental beliefs and behaviors, including their decisions, that are sensitive to the environment in a future work context. Specifically, our hypotheses suggest that a greater degree of implementation of the Environmental Management System (EMS) in universities contributes to develop pro- environmental beliefs and behaviors in its students and also suggests that students will have greater environmental awareness in their future decisions in the world of work. Another hypothesis assumes that a favorable perception towards the environmental strategies of a university is related to more pro-environmental beliefs and behaviors in its students. We also analyze whether the regime of public or private administration of universities implies differences in students' responses. The study was carried out in six Mexican universities, with 495 Students of different Bachelors of Management and Business, in the fourth semester or higher, who they are future decision- makers in companies. Universities were grouped according to the regime of public or private administration and the degree of implementation of an Environmental Management System (EMS): certified, established, and not documented. We used a unique questionnaire with four instruments or scales: the New Ecological Paradigm (NEP), Expressed Ecological Behaviors (CEE, for its acronym in spanish), Awareness of environmental consequences of Executives (CCA-E) and Perception of Environmental Management Policy of the Institution (PPGMI). Contrary to our expectations, the results indicate that the Environmental Management certification has no influence on the pro-environmental behaviors and beliefs of its students, nor does it predict a greater awareness of them about the future consequences of their environmental decisions as executives of companies. Instead, we have found that a favorable perception of the students towards the institution's environmental management policy is related to higher degrees of pro-environmental behavior. And that the items related to collective (social) behaviors interpret better the favorable or unfavorable perceptions of the policy of institutional environmental management. Likewise, we find that in public universities there is a tendency towards more ecocentric behaviors than in private universities.

▼ The aim of the present thesis is to analyse the existent relationship between productive activities and CO2 emissions generated in Ecuador. On the basis of the input-output approach, three chapters are developed allowing a better understanding of this relationship. The first chapter identifies the key sectors in CO2 emissions for the Ecuadorian economy by 2013. The results show that 19 of the 71 productive activities are the most influential in the CO2 emissions generation. Of the 19 activities 8 can be considered as key sectors. The 8 activities are responsible for 60% of the total emissions generated by the productive apparatus; and, 4 of them belong to the services sector, making the last a relevant sector for the analysis of the CO2 emissions generation in the Ecuadorian economy. The second chapter deepens the analysis of the CO2 emissions generated by the activities belonging to the services sector, for which the methodology named "input-output subsystems" is used. This technique allows the identification of several components through which the total emissions (direct and indirect) of a sector or group of sectors are generated. The results show that the emissions directly attributable to the services sector are strongly concentrated in the transport and storage activities. However, However, in the case of other service activities, they have strong pull effect on other activities of the economy. In this respect, activities such as trade, telecommunications, real estate services or government administration, which would be relevant to the design of mitigation policies. The third chapter analyses the factors that are behind the evolution of the CO2 emissions of the services sector in Ecuador between 2007 and 2013. For this, the analysis of input-output subsystems is combined with structural decomposition analysis. The disaggregation of effects presented in this study is greater than that obtained in similar applications, due to the methodology used in the analysis of subsystems. This disaggregation shows results that facilitate the understanding of the elements and the causes that are behind the variation of CO2 emissions of the activities belonging to the services sector. The results indicate that although the expansion of demand is the main cause for the increase of the emissions, there are important asymmetries in the behaviour of the activities of the services sector and the causes that generate those emissions. It is evidenced that some activities show improvements in terms of efficiency and technology which, in some way, compensate the increase in emissions caused by the demand effect. However, other activities, increased their emissions not only due to an upsurge in the demand but also given a deterioration in terms of efficiency and technology.

▼ S'ha fet un estudi faunístic i ecològic dels heteròpters de quatre comunitats vegetals (prat sec, brolla, garriga i alzinar) del Parc Natural del Garraf. Per a cada comunitat vegetal s'han triat tres parcel·les. La presa de mostres s'ha fet mensualment durant els anys 1999, 2000 i 2001, de forma sistematitzada i estratificada sobre la vegetació, en relació al recobriment de cada espècie vegetal. De les 77 espècies trobades, 38 són noves citacions de l'àrea d'estudi, entre les quals destaquen una espècie nova per la ciència, el mírid Orthotylus (Pinocapsus) gemmae Gessé & Goula 2003, el microfísid Loricula ruficeps (Reuter, 1884) que constitueix la segona citació ibèrica, i el pentatòmid Sciocoris maculatus Fieber1851, que és la segona citació de Catalunya. De cada espècie s'indica la seva fenologia i les plantes hoste on s'han trobat. També s'analitzen biogeogràficament les biocenosi d'heteròpters. Es descriu l'estructura i dinàmica de les comunitats d'heteròpters en base a una sèrie d'índexs (densitat, riquesa específica, diversitat, abundància relativa, freqüència, índex de similitud). Excepte a la garriga, les comunitats vegetals presenten una espècie d'heteròpter que domina molt sobre les altres, es tracta de Tingis trichonota (Puton, 1874) al prat sec, Compsidolon crotchi (Scott, 1870) a la brolla i Closterotomus trivialis (Costa, 1852) a l'alzinar. S'estudien també diferents aspectes sobre la relació dels heteròpters amb les seves plantes hoste i sobre el seu règim alimentari. Es constata que cada comunitat d'heteròpters és específica de cada comunitat vegetal de procedència i presenta unes espècies característiques pròpies. Finalment es proposa un protocol de gestió ambiental basat en la prospecció de les plantes i en els mesos on s'han recol·lectat les espècies d'heteròpters característiques de cada comunitat vegetal, que podrien comportar-se com a possibles indicadores de les alteracions del medi.

▼ Two essential aspects of Mediterranean freshwater fish conservation research are addressed in this dissertation: - First, the biology (growth and reproduction) of the more common cyprinids species, Barbus graellsii, B. haasi, B. meridionalis, Chondrostoma miegii and Squalius cephalus was studied. - Second, temporal and spatial changes in fish community structure related to variability of environmental conditions were monitored in several Catalonian river basins: Aigua d'Ora river (Llobregat basin), Llobregat river (Muga basin), Matarranya river (Ebro basin) and Ripoll river (Besòs basin). Field work was done four times a year, in the spring, summer, autumn, and winter, with a total of 13 sampling periods in the Matarranya river (from the summer of 1985 to the summer of 1988), and 11 in the Aigua d'Ora, Llobregat and Ripoll rivers (from the winter of 1987 to the summer of 1990), and it consisted of sampling for biological study and quantitative estimates of fish communities. The five studied cyprinid species (B. graellsii, B. haasi, B. meridionalis, S. cephalus, and C. miegii) fell into one of two possible life history patterns: - Fish populations inhabiting temporal Mediterranean rivers present a periodic strategy characterized by large size, slow growth, and moderate reproductive effort. - Fish populations inhabiting permanent Mediterranean rivers present an opportunistic strategy characterized by middle size, fast growth and high reproductive effort. Mediterranean fish communities are highly persistent and their stability varies from moderately stable, in permanent Mediterranean rivers, to highly fluctuant in temporal Mediterranean rivers. In all cases, persistence of introduced species is very small and the populations of these species fluctuate widely. Secondary production of Mediterranean river fish communities is very high (the one in the Matarranya river is the highest recorded in scientific literature) and P/B ratios are directly correlated with the reduced amount of the annual discharge in relation to the mean annual discharge characteristic of each river.

▼ This work is the result of a search for general (or nearly general) regularities at ecosystem level, and an exploration of their practical relevance in our relations with the environment. I began by adding some new contributions to the thermodynamic approach to systemic ecology, but concluded that there is little scope for further progress of strictly ecological interest with this orientation. Instead, the key for a systemic ecology seems to lie in the "large number" effects that arise at the limit of many organisms and/or species, just like the whole scientific body of statistical physics stands on the general features that emerge at the limit of many particles. The concept of criticality seems to have a special importance within this context (criticality is the quality of lying at the critical point in which there is a second order phase transition). Some specific issues that I analyze in depth, taking advantage of the concept of criticality and other concepts related to statistical physics, are: ·Wildland fire dynamics. Practical tools to predict and manage fire in boreal forests and in the Mediterranean. Limits to anthropogenic impacts on tropical rainforests before a major fire catastrophe unfolds. The possible generalization of the findings on wildland fires to other kinds of catastrophes, with emphasis on agricultural pests and epidemics. · Diversity patterns. The origin of species abundance distributions and species-area relations. Their interpretation (and misinterpretation). The case of marine phytoplankton. The quantification of diversity for conservation purposes. · The effects of diversity on stability. The sources of the apparent inconsistencies between theoretical models, both historical and current, and between theoretical expectations and some experimental results. I conclude with a discussion on the interest of my and other related findings from the point of view of ecological economics. Advisors/Committee Members: Flos Bassols, Jordi (director).

▼ Els éssers vius es divideixen filogenèticament en eucarionts, amb un nucli ben definit, i bacteris. Hi ha dos tipus de bacteris, els eubacteris i els arqueobacteris. Els arqueobacteris tenen, entre altres diferències, una estructura lipídica diferent de la resta d'organismes. Aquesta característica fa que els lípids arqueobacterians siguin utilitzats com a biomarcadors. S'ha estudiat un grup d'arqueobacteris, el bacteris metanògèns, que generen metà com a subproducte del seu metabolisme, característica que els diferencia de la resta d'organismes. Els bacteris anaerobis metanògens, es troben en els digestors anaerobis de les depuradores urbanes i també en ambients extrems com poden ser les salines. Els objectius de la tesi han estat: a) l'obtenció de cultius d'enriquiment de bacteris metanògens a partir de fang de digestor anaerobi de depuradora, amb substrats acetat i dimetilsulfur, i de tapet microbià de salines, amb substrat dimetilsulfur; b) l'estudi de la biodegradació de compostos orgànics de cadena llarga amb significació geoquímica per part de consorcis metanogènics obtinguts a partir de fang de digestor anaerobi de depuradora urbana, i c) l'estudi dels lípids dels cultius obtinguts. Els cultius d'enriquiment s'han efectuat en vials tancats, en medi líquid i sota atmosfera de nitrogen. El creixement bacterià s'ha establert mesurant la variació de la proporció de metà a la part superior del vial. El metà ha estat identificat i quantificat amb cromatografia de gasos, a partir del temps de retenció i l'àrea del pic respectivament. En els cultius amb substrat dimetilsulfur inoculats a partir de fang, el creixement s'ha establert amb cromatografia de gasos acoblada a espectrometria de masses (CG-EM), el que ha permès observar l'augment, sicrònicament al desenvolupament del cultiu, dels fragments característics del metà respecte els de l'atmosfera inicial de nitrogen. La tècnica de CG-EM també ha permès establir la via de degradació del dimetilsulfur. S'ha estudiat la biodegradació anaeròbia de 1-hexadecè i n-hexadecantiol per part de consorcis metanogènics obtinguts a partir de fang de digestor anaerobi de depuradora. És conegut que en la biodegradació anaeròbia de compostos orgànics de cadena llarga intervenen diversos grups de bacteris, que successivament oxiden el compost de cadena llarga a àcid, el qual és degradat perdent successives molècules d'acetat, que és finalmet consumit pels bacteris metanògens, produïnt-se metà i diòxid de carboni. S'ha establert la biodegradació dels dos compostos esmentats, mesurant lal propoció de metà, que ha augmentat en tots els cultius després d'una readdició de substrat. Cal mencionar que la biodegradació de n-hexadecantiol no s'ha trobat descrita amb anterioritat a aquesta tesi. L'anàlisi lipídica dels cultius obtinguts en aquest treball s'ha dut a terme mitjançant extracció orgànica i anàlisi amb CG-EM prèvia sililació de les mostres. El bis-difitanilglicerolèter (C20, C20), lípid exclusiu dels arqueobacteris, ha estat identificat a… Advisors/Committee Members: [email protected] (authoremail), false (authoremailshow), Solé Sardans, M Montserrat (director), Heras i Cisa, F.
