Full textThe present research wants to reveal if the administrative jurisdiction mutates its nature in an objective sense when the administrative judgment begins from the procedural initiative of the independent administrative authorities. In order to answer to this question, the study initially focuses on the “nature” of jurisdiction, frequently opacified by substantive and finalistic evaluations which, not distinguishing the nature from the purpose of jurisdiction, attribute exorbitant relevance to the qualification of the interest that gives life to the judgment. It is necessary, instead, to distinguish the essence from the purpose of a judgment, identifying the first through an investigation aimed at observing the formal structure and rules of the process. Once the method of analysis has been identified, it can be applied to the Italian administrative judgment, initially in its ordinary physiognomy, and following - in response to the questio iuris of the research - in the special physiognomy that assumes when it begins from by the legal standing of the independent administrative authorities (in particular, of the Autorità Garante della Concorrenza e del Mercato, Autorità di Regolazione dei Trasporti and Autorità Nazionale Anticorruzione). This investigation allows to realize that the administrative judgment, even if it starts thanks to the impulse of these Authorities, remains a subjective process. In any case, a possible opposite outcome, in the sense of objectivity, both of legal standing and of jurisdiction, would not have been contrary to Constitution. The constitutional rules, in fact, must be understood as guarantee rules, which set a minimum of protection, without precluding broader safeguard. The last part of this research deals with the comparation between the Italian legal system and the Spanish one. Also with regard to this system, the study analyses the Spanish administrative justice, in order to identify, even here, the nature of the Spanish administrative process, first in its ordinary physiognomy, then when the judgment is started by an independent administrative authorities such as the Comisión Nacional de los Mercados y la Competencia. The outcome is opposite to that emerged in relation to the Italian legal system, given that in the Spanish administrative process the objective nature of judgment is always very clear and intense. As a result of this comparison, however, it is necessary to internalize the awareness that the administrative judgments are connected with protection requirements that do not concern only the subjective protection of the applicant, with the consequent need to configure a process that values the objective reasons of public interest, including access to justice. These reflections are not so widespread in our legal system, where the undertaken path towards the subjectivity and the effectiveness of judicial protection risks to generate a lack of awareness of the strong bond that unites the administrative process to the public interest. It is therefore necessary not to deny, but rather to highlight, the full dignity both of the objective powers of the procedural initiative, as well as of the rules that give objectivity to the judgment, in order to more successfully combine the effectiveness of the subjective jurisdictional protection of the applicant with the protection of the objective reasons of public interest.

Full text[CA] Les àrees naturals protegides de l'Equador, enfronten diverses amenaces ambientals, d'entre les quals, el pasturatge és una de les més greus en diversos Parcs Nacionals (PN), incloent el Parc Nacional Cotopaxi (PNC). Des de la gestió d'alguns parcs nacionals s'estan proposant alternatives d'acció per compaginar els objectius de conservació ambiental dels PN amb la pastura, al mateix temps que es promou el desenvolupament social i econòmic dels ramaders del lloc i d'altres actors socials que depenen dels recursos naturals del PNC. En aquest context s'emmarca la proposta d'aquesta tesi per a l'avaluació participativa de la sostenibilitat del pasturatge en els PN. Per elaborar la metodologia de treball, que s'aplica a l'PNC però es proposa estendre-la a altres PN comparables, s'han utilitzat tres cnocidas eines: de l'anàlisi de xarxes socials (ARS), l'Anàlisi de Poder (AP) i Procés Analític de Xarxa (Analytic Network Process, ANP). El ARS va ser aplicat per obtenir la xarxa social que modela el pasturatge en el PNC. Aquesta tècnica va permetre identificar fins a 169 actors relacionats amb la sotenibilitat del pasturatge en el PNC. D'aquests, 39 van poder ser entrevistats i la resta va caldre descartar-los per diversos motius. El ARS va permetre avaluar la importància dels actors per a la comunicaió sobre el pasturatge, així com també els seus vincles i fluxos d'informació. El AP va ser desenvolupat per completar l'estimació de la importància dels actors avaluats. Es van analitzar, els poders visible, ocult i invisible per conèixer el poder real dels actors. Això permetrà elegir els actors més influents per a la participació en l'avaluació de la sostenibilitat del pasturatge en el PNC. I d'altra banda, permet estudiar què passaria si el poder d'aquests actors s'inclogués en el model d'avaluació participativa desenvolupat amb ANP. El ANP permet modelar un problema d'avaluació com un problema de decisió, incloent les diverses variables o criteris que determinen la sostenibilitat del pasturatge, i incloure als actors socials en l'avaluació de les alternatives de solució. En la metodologia presentada, un panell d'experts en maneig d'àrees naturals va determinar el model d'avaluació, això és la xarxa de criteris de valoració i les alternatives de solució agrupades en clústers. I un panell amb els actors triats després de l'aplicació de l'ARS i el AP va avaluar la importància dels criteris i la sostenibilitat de les alternatives. Els resultats de la investigació confirmen que els actors socials tenen diferents interessos, sensibilitats i formes de comprendre la sostenibilitat. A més es va poder identificar aquests interessos i estimar la seva importància. Gràcies a l'aplicació del model ANP, els actors que van participar comprenen millor els seus interessos i els dels altres actors. Així, una participació millor fundada va ser obtinguda i el consens, o almenys acords generals, són més probables. També, s'aconsegueix un major compromís cap a l'objectiu general de conservació ja que el model de decisió facilita la millora del disseny d'alternatives de solució per disminuir el possible perjudici per a alguns actors, o per l'ambient. Finalment, en relació als resultats, per al cas de la sostenibilitat del pasturatge en el PNC, els principals criteris que s'han de tenir en compte són: Contaminació atmosfèrica causa de la crema de pastiales, i Contaminació d'aigües superficials. Entre les estratègies per dur a terme un pasturatge més sostenible són: Desenvolupament d'alternatives productives al pasturatge i Control d'ingrés de bestiar / Delimitació física del parc.
[EN] The natural protected areas of Ecuador face several environmental threats, among which grazing is one of the most serious in several National Parks (PN), including Cotopaxi National Park (PNC). From the management of some national parks, alternatives for action are being proposed to reconcile PN's environmental conservation objectives with grazing, while promoting the social and economic development of local livestock farmers and other social actors that depend of the PNC's natural resources. In this context, the proposal of this thesis for the participatory evaluation of the sustainability of grazing in NPs is framed. In order to elaborate the work methodology, which is applied to the PNC but is proposed to be extended to other comparable PNs, three tools have been used: Social Network Analysis (SNA), Power Analysis (AP) and Analytical Network Process (ANP). The ARS was applied to obtain the social network that models grazing in the PNC. This technique allowed the identification of up to 169 stakeholders related to the sustainability of grazing in the PNC. Of these, 39 could be interviewed and the rest had to be discarded for various reasons. The SNA allowed evaluating the importance of the actors for communication about grazing, as well as their links and flows of information. The AP was developed to complete the estimation of the importance of the actors evaluated. They visible, hidden and invisible powers were analyzed to know the real power of the actors. This will allow choosing the most influential actors for participation in the evaluation of the sustainability of grazing in the PNC. In addition, on the other hand, it allows studying what would happen if the power of these actors were included in the participatory evaluation model developed with ANP. The ANP can model an evaluation problem as a decision problem, including the various variables or criteria that determine the sustainability of grazing, and including social actors in the evaluation of alternative solutions. In the methodology presented, a panel of experts in natural area management determined the evaluation model, i.e. the network of valuation criteria and solution alternatives sorted in clusters. Following, a panel with the chosen actors after the application of the ARS and the AP evaluated the importance of the criteria and the sustainability of the alternatives. The research results confirm that social actors have different interests, sensitivities and ways of understanding sustainability. Furthermore, these interests could be identified and their importance assessed. Thanks to the application of the ANP model, the actors who participated understand better their interests and those of the other actors. Thus, a better founded participation was obtained and consensus, or at least general agreements, are more likely. Besides, a greater commitment towards the general objective of conservation is achieved since the decision model facilitates the improvement of the design of alternative solutions for reducing the possible harm to some actors, or to the environment. Finally, in relation to the results, in the case of sustainability of grazing in the PNC, the main criteria that should be taken into account are: Atmospheric pollution due to burning of grasslands, and Contamination of surface waters. Among strategies to carry out a more sustainable grazing, most preferred are: Development of productive alternatives to grazing and Control of cattle entry / Physical delimitation of the park.

Full textIn tacking the efficiency problem, our approach has been to prune the search space of the parser by integrating shallow and deep processing. We propose and implement a NLP system which integrates a Part-of-Speech (PoS) tagger and chunker as a pre-processing module of broad-coverage nification-based grammar of Spanish. This allows us to release the arser from certain tasks that may be efficiently and reliably dealt with by these computationally less expensive processing techniques. On the one hand, by integrating the morpho-syntactic information delivered by the PoS tagger, we reduce the number of morpho-syntactic ambiguities of the linguistic expression to be analyzed. On the other hand, by integrating chunk mark-ups delivered by the partial parser, we do notonly avoid generating irrelevant constituents which are not to contribute to the final parse tree, but we also provide part of the structure that the analysis component has to compute, thus, avoiding a duplication of efforts.
In addition, we want our system to be able to maintain the accuracy of the high-level grammar. In the integrated architecture we propose, we keep the ambiguities which can not be reliably solved by the PoS tagger to be dealt with by the linguistic components of the grammar performing deep analysis.
Besides improving the efficiency of the overall analysis process and maintaining the accuracy of the grammar, our system provides both structural and lexical robustness to the high-level processing. Structural robustness is obtained by integrating into the linguistic components of the high-level grammar the structures which have already been parsed by the chunker such that they do not need to be re-built by phrase structure rules. This allows us to extend the coverage of the grammar to deal with very low frequent constructions whose treatment would increase drastically the parsing search space and would create spurious ambiguity. To provide lexical robustness to the system, we have implemented default lexical entries. Default lexical entries are lexical entry templates that are activated when the system can not find a particular lexical entry to apply. Here, the integration of the tagger, which supplies the PoS information to the linguistic processing modules of our system, allows us to increase robustness while avoiding increase in morphological ambiguity. Better precision is achieved by extending the PoS tags of our external lexicon so that they include syntactic information, for instance subcategorization information.

Full textChile, es un país que está permanentemente expuesto a riesgos de origen natural o antrópico, por lo que la gestión de riesgos se ha instaurado como una prioridad (ONEMI, 2014). La normativa chilena, en su decreto N° 156, define las etapas del ciclo de gestión de riesgos: Prevención, Mitigación, Preparación, Respuesta, Rehabilitación y Reconstrucción. El proceso de Rehabilitación consiste en la recuperación de los servicios básicos e inicio de la reparación del daño físico, social y económico. Este proceso se destaca por entregar beneficios según el tipo de evento natural y las necesidades de la población. El objetivo de este estudio es analizar los obstaculizadores y facilitadores del proceso de rehabilitación post desastre natural, con el propósito de optimizar el ciclo de gestión de riesgos en Chile. La investigación se realizó a partir de una investigación cualitativa de tipo descriptivo, mediante el análisis de documentos institucionales (leyes, decretos, resoluciones, etc.) y a través de entrevistas semi-estructuradas a los actores relevantes del proceso de rehabilitación, en particular para el caso del Terremoto y Maremoto de Coquimbo año 2015. Los resultados del estudio permiten detectar que el proceso de rehabilitación presenta una maduración en las instituciones relevantes, que les permite auto-estructurarse en torno a una forma de operar frente a los desastres y, además, cuenta con un importante recurso tecnológico que permite mejorar la toma de decisiones. A pesar de aquello, la institucionalidad que soporta el proceso de rehabilitación no es suficiente, ya que en ella no existen lineamientos específicos en relación a los tipos de soluciones que debería abarcar. Por otro lado, la falta de conocimientos técnicos y capacitaciones para los funcionarios de las instituciones regionales que se enfrentan a la emergencia provoca importantes falencias en los momentos iniciales del proceso. Además, no existen recursos financieros regulares y disponibles para mitigar los riesgos de emergencia ni para responder cuando esta ocurre. Disminuir los obstaculizadores que emergieron de este estudio, solo será posible mediante la implementación de políticas públicas que apunten en esta dirección y que consideren planes de capacitación, aumento de recursos basales del Estado para la gestión del riesgo y la construcción de un enfoque integral de la reducción de riesgo de desastres.

Full textLa transglutaminasa (TGasa) es una enzima que cataliza modificaciones postraduccionales de proteínas mediante enlaces ε- (γ-glutamil) y puentes covalentes de amida. En plantas, esta enzima está poco estudiada, y sólo ha sido clonado el gen TGasa de Zea mays (tgz). Esta tesis resume el trabajo realizado para desarrollar un sistema de expresión utilizando dos microorganismos recombinantes, Escherichia coli (E. coli) y Pichia pastoris (P. pastoris) para producir y caracterizar la enzima transglutaminasa (TGZ). Trabajos anteriores en E. coli mostraron que la proteína recombinante estaba presente principalmente en forma de cuerpos de inclusión (IBs). Con el fin de obtener la proteína en forma activa y soluble, se optimizaron las condiciones de expresión en E. coli. Se ensayó la coexpresión de chaperonas y se desarrolló un sistema no clásico de solubilización de IBs. Además, se transformó P. pastoris para estudiar su expresión y comparar ambos sistemas. Se utilizaron las metodologías de Taguchi y de la superficie de respuesta para formular un medio de cultivo que, junto con el desarrollo de una aplicación informática para modelar y simular el proceso, permitieron establecer un cultivo de alta densidad de E. coli. Los resultados mostraron que las condiciones óptimas para expresar TGZ en E. coli fueron de una concentración de IPTG de 100μmol IPTG / g de biomasa seca y un tiempo de inducción de 5 h. Estas condiciones permitieron obtener un rendimiento TGZ de 160 mg / L con una actividad específica de 450 putrescina pmol / mg TGZ resolubilizada · h. Se realizó una caracterización bioquímica completa de la TGZ obtenida mediante E. coli. Se puso a punto un sistema de cultivo de alta densidad celular en P. pastoris y se expresó TGZ con éxito. La reacción de reticulación de TGZ en la caseína se estudió, y el resultado fue igual que la reacción de la caseína por TGZ expresada en E. coli. Se obtuvo una producción de 480 mg / L de proteína total con una actividad de 4000 pmol putrescina / mg de proteína total · h. Estos resultados indican que también se estableció un procedimiento eficaz para expresar TGZ en P. pastoris.
Transglutaminase (TGase) is an enzyme that catalyzes post-translational protein modifications by ε-(γ-glutamyl) links and covalent amide bonds. In plant, this enzyme is poorly studied and only the Zea mays TGase gene (tgz) has been cloned. This thesis summarizes the work done to develop an expression system using two recombinant microorganisms, Escherichia coli (E. coli) and Pichia pastoris (P. pastoris) to produce and characterize the enzyme transglutaminase (TGZ). Previous works expressing TGZ in E. coli showed that the recombinant protein was mainly present as inclusion bodies (IBs). In order to obtain active, soluble protein, expression conditions were optimized in E. coli, coexpression of chaperones was tested and a non-classic IBs resolubilizing system was developed. Additionally, the gene was also inserted in P. pastoris to study its expression, being able to compare both systems. Taguchi and response surface methodologies were used to develop a culture media that, together with the implementation of a computer application to model and simulate the process, allowed to develop a high-density culture of E. coli. Results showed that the optimal conditions to express TGZ in E. coli were an IPTG concentration of 100µmol IPTG/ g dry biomass and an induction time of 5h. These conditions allowed to obtain a TGZ yield of 160 mg/L with a specific activity of 450 pmol putrescine/mg resolubilized TGZ·h. A full biochemical characterization of the TGZ obtained using E. coli was performed. A P. pastoris high cell density cultivation system was implemented and TGZ was successfully expressed. The cross-linking reaction of TGZ to the casein was also studied, and the result was same as the reaction of casein by TGZ expressed in E. coli. A production of 480mg/L of total protein with an activity of 4000 pmol putrescine/mg total protein·h was obtained. These results indicated that an effective procedure for expressing TGZ in P. pastoris was also established.

Full textConservation needs strategic foresight leading to effectively address the ongoing challenges posed by global change. Mediterranean Basin has been identified as priority area for conservation, particularly vulnerable to the combined effects of climate change, land-use change and fire disturbance regime. The interacting effects of these drivers, and the large uncertainties associated to their forecasting, might also bring conservation opportunities to intervene through better policies. Strategic foresight exercises may offer decision-makers with tools to creatively think about the future and make decisions that create a more desirable future. In this thesis, we illustrate the role for horizon scanning, scenario planning and simulation-based scenario analysis in underpinning the strategic foresight approach — using storylines as conceptual scenarios, and simulations as numerical estimates of future environmental changes. In particular, this strategic foresight exercise contributes to opening up two promising fire management policy options (‘letting unplanned fires burn’ and ‘forest biomass extraction for bioenergy uses’) alternatives to the current fire suppression paradigm of “stopping all fires’’. Both fire management policies could be strategically combined in order to achieve the fuel reduction objectives required to mitigate the increasing impact of large fires caused by global change. Conservation planning may be considerably improved through the implementation of such fire management strategies. Two main emerging conservation opportunities have been identified and should be prioritized in order to effectively protect community-interest bird species in the near future: 1) promoting early-succession stages of vegetation for open-habitat dwelling species through ‘letting unplanned fires burn’ policies; and 2) increasing the resilience of key forest habitats to climate change for forest-dwelling species. This thesis emphasizes the need for an integrative conservation perspective wherein agricultural, forest and fire management policies should be explicitly considered to effectively preserve key habitats for threatened birds in fire-prone, highly-dynamic systems. Our findings also shed light about the importance of considering landscape dynamics and the synergies between different driving forces when assessing the long-term effectiveness of fire management at reducing fire risk and safeguarding biodiversity in Mediterranean-type ecosystems.

Es conocido que el ser humano realiza intervenciones diferentes, directas o indirectas, y a pesar de que observamos con frecuencia elevadas pérdidas de vidas y económicas, suelen ser fenómenos insuficientemente comprendidos en su alcance y consecuencias. La presente investigación trata de estructurar conocimientos para mejorar la relación del ser humano con el ambiente. Se pretende concretar un diagnóstico del nivel de Alfabetización Ambiental de una muestra de la población pre universitaria de la Universidad de Buenos Aires y también, de lograr una herramienta que permita reducir la brecha entre el conocimiento científico y el saber popular, para generar un capital humano y social sensible y comprometido con la problemática ambiental y que posibilite el desarrollo de futuras investigaciones para que las personas actúen de manera responsable ante los fenómenos adversos. La tesis se ha desarrollado a partir de una descripción de la problemática educativa, los fallos de mercado y, las crisis de valores y falta de oportunidades, como contextualización para aproximar a la población los conocimientos mínimos necesarios para facilitar la salida del analfabetismo ambiental. Se expone el estado del arte socio ambiental y económico, describiendo las actividades antrópicas impactantes en el medio. Se concluye la parte expositiva focalizándose en lo conductual, tanto en lo ético como en la moral social y en la compatibilización entre la Educación Ambiental y el Desarrollo Sostenible. Se menciona la problemática de la Población y el trabajo, las consecuencias socio económicas del empleo y el desempleo, la pobreza y la inequidad de la distribución de la renta nacional, la participación social y el involucramiento individual y comunitario en la toma de decisiones relativas a los problemas ambientales. La parte experimental se despliega mediante la presentación del caso y sus conclusiones, con los resultados de la investigación: es posible inferir que los estudiantes promedio de la muestra poblacional de la universidad pública estudiada, disponen de poco conocimiento de la problemática ambiental lo cual no les facilita involucrarse ni comprometerse, pero queda demostrado que sin educación, sin Alfabetización Ambiental, es imposible conseguir su sensibilización a la problemática o el involucramiento social en la búsqueda de solucionar, mitigar o reducir los impactos adversos

Full textWorldwide, the pesticides use has contributed significantly to the improvement and increase of food production. However, its indiscriminate and uncontrolled use has caused the emergence of resistant pests, soil pollution, air and mainly water, as well as the intoxication and death of various living organisms. Methamidophos is a systemic organophosphate pesticide with insecticidal and acaricide, banned in many countries for being considered a high toxicity pesticide due to adverse effects on the environment and human health. However, in Mexico, it is the second most widely used pesticide. It should be noted that most publications related to its quantitative determination uses High-Performance Liquid Chromatography (HPLC) or Gas Chromatography (CG) coupled to Mass Spectrometry (MS), these methods are extremely expensive and few laboratories in Mexico count on them. In addition, the conventional methods of elimination for this type of pollutants have not been proven effective, so, over the last decade, researchers have focused on methamidophos elimination by diverse methods, among which adsorption is not reported yet. This is an efficient, low-cost and accessible method for various pollutants; and in recent years, many new adsorbing materials have been investigated, including modified zeolitic materials with various surfactants. Evaluating the thermodynamic parameters involved, such as enthalpy (ΔH°), entropy (ΔS°) and free Gibb energy (ΔG°) are useful for determining the nature and type of mechanism that predominates in an adsorption process. Due to the aforementioned problems, it is important to propose new methods for the treatment of water containing this type of pollutants so this research report for the first time, on this pesticide adsorption behavior in potential adsorbent materials that allow their efficient disposal such as zeolitic materials modified with a cationic surfactant, as is HDTMA, thus opening a very wide research panorama in this area. This research carried out a systematic study on methamidophos adsorption behavior on the studied zeolitic materials, depending on diverse physicochemical parameters such as the contact time effect, and methamidophos concentration; likewise, the HDTMA-modified zeolitic material with greater adsorption capacity was selected, and only in this material was evaluated the adsorbent amount, pH effect and temperature effect of the solid/liquid systems to study and were determined thermodynamic parameters.

Full text--- The objetive of the following advanced study is to prove the validity of the Didactic Model Stages of Research to develop among the students scientific attitude for the contenys of natural sciences and improve the process of learning of new ideas or opinions. This learning proess es diffilcult by nature. Consequently, it is necessary to compel students to diverse experimental activities throug classes with the Didactic Model to set out and compare the academic performance of the Experimental Group of students in contrast with the Control Group. With this trial we will show that the improvement of the esperimental group proves the self-sufficiency in comparison with the professosr, to analyze problems, formulate hypotheses, and undergo experiences of auto-learning and arrive to conslusions scientifically valid. At the same time to create and keep ideas and opinions internally. In this research work, we use the technologic descriptive inverstigation, almost experimental and explicatory to prove that the teaching and learning process trough research in saml working groups anda applying a scientific method wil improve the academic accomplishment among the students. The purpose oif this study is to find the highest achievement among the students in the learning process and the development of a scientific attitude through the Stage of investigation in contrast with the explanatory method. The diverse results obtained in this Research throug a statistical process with the statistic model called Latin Square and the analysis of the variation, alloved us to arrive to the most important conclusions: • The experimental study relized through the Didactic Model of Stges in Investigation has permitted to develop among the students a better inclination and attitude to observation, in order to formulate hypotheses, to design and carry on experimental activities attempted by the students as an explanation of the observed phenomennon. • The put in practice the Didactic Model Stages of Investigation improves the comprehension of the conceptual thinking and the development of the scientific attitude of the students. • The learning process of the experimental work mis shown with the self sufficiency in relation with the attitude of the professor to carry on practices of self learning and arrive to valid scientitic conclusions and formulate and keep concepts internally. • The qualitative results obtained from the students of the experimental group show that they have been remarkable higher than the ones obtained by the students of the control group driven by the explanatory method.

Full textCoastal wetlands in shallow tidal systems are among the most valuable environments on Earth, as they provide a diverse range of ecosystem services. Nevertheless, their survival is questioned by increasing rates of sea-level rise and reduced fluvial sediment delivery to the coasts. Moreover, anthropogenic pressures are becoming increasingly significant, as densely populated coastal urban areas are adopting protection infrastructures to reduce flooding, such as storm-surge barriers, whose potential effects on the evolution of the surrounding coastal wetlands are still poorly investigated. Therefore, a better understanding of the effects of natural and anthropogenic processes affecting the morphological evolution of coastal wetlands is crucial to develop management strategies aiming at preserving and restoring these delicate environments and the precious ecosystem services they provide. With this aim, in the present work we start considering sediment erosion and transport dynamics on tidal flats and test the possibility to develop a synthetic theoretical framework to realistically describe erosional and depositional processes in the long-term time scale. Beyond determining the evolution of tidal flats, sediment reworking is also a major mechanism controlling salt-marsh sedimentation, offsetting the negative effects of sea-level rise. This is particularly true in sediment starved systems. Hence, using field measurements from the Venice Lagoon (Italy), a representative case of sediment starved back-barrier system, we investigate the effects of continually varying influences of natural processes on temporal and spatial sedimentation patterns on salt marshes. Finally, combining field data and numerical modelling of the first-ever closures during Fall 2020 of the storm-surge barriers designed to protect Venice, we evaluate the impacts of anthropogenic flood regulation on salt-marsh sedimentation and on the morphological evolution of the tidal basin as a whole. The main results from this work highlight that: i) bottom shear stress and suspended sediment concentration dynamics can be modelled as marked Poisson processes, thus bearing important consequences for realistic, sta\-ti\-sti\-cal\-ly-based analyses of the long-term biomorphodynamic evolution of tidal landscapes; ii) the high temporal variability in sediment reworking due to the combined action of tide, waves and storm surges affects salt-marsh sedimentation, with intense storm surges accounting for the large majority of sediment accumulation on salt marshes, despite their brief duration; iii) the combination of these varying hydrodynamic forcing factors also affect spatial sedimentation patterns, which thus cannot be interpreted solely as an essentially tide-driven process and sign the marsh topographic profile; iv) flood regulation, by modifying hydrodynamic and sediment transport processes during storm surges, which are largely responsible for sediment delivery in the upper intertidal frame, significantly reduces sedimentation on salt marshes thus affecting their resilience to sea-level rise; v) at the basin scale, even though storm-surge barrier operations can temporarily reduce the net sediment loss from the system, flood-regulation promotes a less-diverse geomorphological structure, rather than contributing to the preservation of tidal landforms.

Full textel objetivo principal de esta investigación consistió en diseñar, acondicionar e implementar, bajo un enfoque sistemático, un conjunto combinado de etapas orientadas a la generación de una alternativa para la depuración de arsénico presente en agua con alto contenido de bicarbonatos y sulfatos, basada en el proceso de adsorción, llevado a cabo en presencia de soluciones multiiónicas. Para el cumplimiento de este objetivo se partió, metodológicamente, de la caracterización fisicoquímica espacio-temporal de las fuentes en la zona de estudio para, a partir de dicha composición, proceder a la formulación de soluciones sintéticas. Con ellas se realizaron, a nivel de laboratorio, pruebas dinámicas de adsorción de arsénico sobre clinoptilolita natural y modificada químicamente. La simulación de la cinética de adsorción muestra que, en función de los valores de los índices de ajuste r2 (0.9975), ERRSQ (0.0018), HYBRID (0.3245), MPSD (40.8751), ARE (0.4115) y EABS (0.0840), el modelo no lineal de Thomas es el más idóneo para representar el proceso de adsorción dinámico de As. Se demostró la existencia de divergencia en la estimación paramétrica de los modelos comparando sus formas lineales y no lineales, situando a esta última como la más adecuada para tal fin. El enfoque desarrollado permite la generación de una alternativa de mejora de la calidad de agua destinada a consumo humano para los municipios de Ixtapan de la Sal y Tonatico y permite, a partir de su sistematización, su aplicación posterior en otras regiones de naturaleza kárstica con problemas de contaminación similares.

Full textThe aim of the present study is to analyze the “giudizio direttissimo” – one of the different forms that criminal trials can take in Italy – from the perspective of the Italian Constitution. In this particular kind of trial, the accused is immediately brought before the Court to be publicly judged, without any kind of preliminary hearing to assess whether the charge is well-founded or not. On one hand, the “giudizio direttissimo” seems to be consistent with the principle – laid down in the Italian Constitution – that a trial must be held within a reasonable time of time. Indeed, the omission of the “preliminaries” – that characterize the “ordinary proceeding” – allows a saving of one year and a half, when compared to the average length of the latter. On the other hand, the course of this kind of trial, in some cases, doesn’t seem to give the accused enough time to prepare an adequate defence. Moreover, its discipline seems to be lacking in some of the most important constitutional rights. A constitutionally consistent interpretation of the “giudizio direttissimo” might help to solve the aforementioned issues, by limiting its application only to the easiest cases. In addition, some case-law which is too rigorous for the defendant should be overridden.

Full textThe aim of this Doctoral Thesis in the Flix reservoir and the lower part of Ebro river part was to determine the Naturally Occurring Radioactivity waste materials (NORM) contained in Flix Reservoir sediments due to the dicalcium phosphate (DCP) production of a factory located in the reservoir vicinity, and evaluate the potential remobilization of the NORM waste materials downstream, along the 95 km of Ebro river until its river mouth delta (Ebro Delta). The results display an evident radiological impact in the waste materials dumped in Flix reservoir with maximum values of values 11723±198 Bq kg-1 238U, 9361± 181 Bq kg-1 226Ra, 3500±157 Bq kg-1 210Pb, 308 (238U), 92 (226Ra) and 38 (210Pb) times higher than the activity of these radionuclides in the Ebro sediments, that show an average activity of 20 Bq kg-1. In order to determine the mobilization of the radioactivity, 226Ra (dissolve) was studied. An enhancement of the 226Ra levels in water was detected in the Flix water (8.00.4 Bq m-3) and specially in the Flix meanders with a value of 37.5 ±1.2 Bq m-3, typical of the contaminated NORM rivers. However the rest of the lower part of the river water samples display non contaminated levels of 226Ra, with an average value of 5.9 ±1.6 Bq m-3.
In Camarasa reservoir the aim of the research was to establish the sedimentation rates by 210Pb models (CFCS) and 137Cs dating mark, that allows us to date the last 100-150 years. The highest sedimentation rate in the central and lower part of the reservoir was 3.3 ± 0.2 cm yr-1 (14.1 kg m-2 a-1), close to the dam, due to the dam barrier effect that block the water stream. The central part of the reservoir displays a lower sedimentation rate of 1.370.14 cm yr-1. We have to take into account the effect of the flood events in the assessment of the sedimentation rates. In this study a punctual flood event in November 1982 was registered in the sediments depositing from 30 to 40 cm of material in 1 week, equivalent to 25 years of normal sedimentation in the central part of the reservoir.
In the Pyrenees lake study, the distribution of 210Pb (0 to 5178 ± 1300 Bq·kg-1) and 137Cs (8 to 2970 ± 101 Bq·kg-1) displays a wide variation activity ranges, typical of remote lakes. 210Pb was used as a normalizer of the heavy metal (Zn and Cd) contaminations and some organochlorate compounds (Hexachlorobenzen and Hexachlorociclohexan) in order to detected contamination sources. The metal results display an evident Zn and Cd contamination in some lakes of Vall d'Aran area (Pica Palomera and Montoliu lakes) due to the mining activity during the period from 1740 to 1968. On the other hand, the normalized organochlorinate compounds display a source of contamination close to Sabiñanigo village (Aragon Pyrenees) probably due to the presence in the past of an Hexachlorociclohexan factory.

Full text[CA] La matèria primera és un element clau en qualsevol procés de transformació alimentària, ja que de la seua composició i qualitats dependrà el producte final. En el cas del pernil, l'origen de la matèria primera, pot procedir de sistemes ramaders convencionals, on la producció és intensiva i l'alimentació està basada en pinsos comercials. En el cas de porcs procedents de ramaderia ecològica, els animals estan subjectes a les condicions marcades per la normativa europea de producció ecològica, on es respecta el medi ambient i el benestar animal. Per al cas de figures de qualitat, les explotacions ramaderes també han de complir els requisits indicats en els plecs de condicions. Un altre element que defineix al pernil curat és el procés d'elaboració, que s'inicia amb la salaó, amb o sense sals nítriques. El temps de l'assecatge-maduració on la duració, el sistema d'assecatge (natural o amb finestra oberta versus cambra amb condicions controlades) i la temperatura són elements clau en el desenvolupament de les qualitats organolèptiques. El principal objectiu del present estudi és aportar resultats sobre l'evolució en la composició de la carn, al llarg del procés d'assecatge-maduració, en l'elaboració de pernil curat, tenint com a variables de l'estudi, la procedència del pernil (de granges ramaderes convencionals, ecològiques o de la DOP Teruel), tecnologia aplicada en el procés d'assecatge (complint els requisits per a la certificació ecològica), així com la influència del sistema d'assecatge (finestra oberta o cambra), avaluant els paràmetres que permeten classificar les diferents variables. Per a això s'analitzen un total de 36 pernils de porc blanc, prenent 12 de cadascuna de les procedències objecte d'estudi (convencional, ecològic i DOP Teruel), destinant 6 pernils de cadascuna per a l'assecatge natural i altres 6 per a l'assecatge en cambra. Els paràmetres analitzats són humitat, minerals totals, sodi, ferro, proteïna, greix, perfil d'àcids grassos, nitrats i nitrits, detecció d'antibiòtics i compostos de la fracció volàtil. Els resultats indiquen que els paràmetres de color L*, b* i C* són majors en els pernils procedents de sistemes de producció convencional, en particular en els pernils DOP Teruel, on a més s'inclou el paràmetre a*. Els pernils de sistemes de producció convencional es caracteritzen per presentar valors més elevats d'humitat, greix, proteïna i cendres, així com un contingut en àcids grassos saturats major. Això repercuteix en els valors dels índexs de qualitat del greix, amb connotacions negatives en l'índex de aterogenicitat, de trombogenicitat o en la relació ω6/ω3, sobretot si els pernils s'assequen en cambra. Els pernils ecològics presenten valors més baixos dels components químics analitzats i nivells superiors de AGMI i AGPI, així com índexs positius de qualitat del greix com el d'àcids grassos bons per a la salut o la relació AGPI/AGS, especialment si s'assequen al natural. Generant pernils amb una major presència de compostos volàtils. La classificació dels pernils, en funció de la procedència i el sistema d'assecatge, s'aconsegueix amb èxit prenent els paràmetres de color, àcids grassos i els components terpenoides de la fracció volàtil. L'estudi de components principals permet classificar els pernils convencionals com aquells amb major contingut en proteïna, L*, cendres, Fe, Na, H*, humitat, greix, nitrats i nitrits, així com pels àcids grassos behénic, palmític, esteàric i mirístic. Els pernils ecològics es caracteritzarien pels seus valors de a*, b* i C*, així com per la presència de linoleic i linolènic i els pernils DOP Teruel serien aquells amb alts valors d'àcids grassos heptadecenoic, palmitoleic i oleic.
[EN] The raw material is a key element in any food transformation process, since the final product will depend on its composition and qualities. In the case of ham, the origin of the raw material can come from conventional livestock systems, where production is intensive and food is based on commercial feed. In the case of pigs from organic farming, the animals are subject to the conditions set by the European organic production regulations where the environment and animal welfare is respected. In the case of quality figures, livestock farms must also meet the requirements indicated in the specifications. Another element that defines cured ham is the production process, which begins with salting, with or without nitric salts. The duration of the drying-maturing, the drying system (natural or with an open window versus chamber with controlled conditions) and temperature are key elements in the development of organoleptic qualities. The main objective of this study is to provide results on the evolution in the composition of the meat, throughout the drying-maturation process, in the elaboration of dry-cured ham, having as variables of the study, the origin of the leg (from cattle farms conventional, ecological or of the Teruel PDO), technology applied in the drying process (meeting the requirements for ecological certification), as well as the influence of the drying system (open window or chamber), evaluating the parameters that allow classifying the different variables. For this, a total of 36 white pig hams are analyzed (conventional, organic and PDO Teruel), allocating 6 hams of each for natural drying and another 6 for drying under controlled conditions. The parameters analyzed are moisture, total minerals, sodium, iron, protein, fat, profile of fatty acids, nitrates and nitrites, detection of antibiotics and compounds of the volatile fraction. The results indicate that the color parameters L *, b * and C * are higher in hams from conventional production systems, particularly in PDO Teruel hams, where the a * parameter is also included. Hams from conventional production systems are characterized by higher moisture, fat, protein and ash values, as well as a higher saturated fatty acid content. This affects the values of the fat quality indices, with negative connotations in the atherogenicity index, thrombogenicity or in the ω6/ω3 ratio, especially if the hams dried in controlled conditions. Organic hams present lower values of the chemical components analyzed and higher levels of MUFA and PUFA, as well as positive indices of fat quality such as fatty acids good for health or the PUFA / SFA ratio, especially in natural driying. Generating hams with a greater presence of volatile compounds. The classification of hams, depending on the origin and the drying system, is successfully achieved by taking the parameters of color, fatty acids and the terpenoid components of the volatile fraction. The study of main components makes it possible to classify conventional hams as those with the highest content in protein, L *, ashes, Fe, Na, H *, moisture, fat, nitrates and nitrites, as well as by behenic, palmitic, stearic and myristic. Organic hams would be characterized by their a *, b * and C * values, as well as by the presence of linoleic and linolenic levels, and DOP Teruel hams would be those with high levels of heptadecenoic, palmitoleic and oleic fatty acids.

Full textThe interaction of soil fungi with rocks and minerals is called geomycology. Serpentine rocks belong to the ophiolites family and can contain chrysotile (serpentine asbestos). Asbestos fibres reactivity is related to their surface chemical composition, i. G. The presence of iron, catalysing free radicals release, which is harmful for cells and tissues. Asbestos represents an environmental issue, related not only to serpentine rocks naturally exposed and weathered, but also (and mainly) to asbestos mines and wastes. Soil fungi are good candidates for the bioremediation of asbestos rich soils. The main goal of this thesis is the isolation of soil fungi from asbestos rich soils and the selection of the more suitable to interact and modify asbestos fibres in vitro. The metabolic responses of fungi are also investigated. Verticillium leptobactrum is the most abundant specie in all the serpentinic soils considered. This and interesting result, since this specie has bees previously seldom isolated. V. Leptobactrum and other fungal species are able to extract iron and magnesium from chrysotile and crocidolite fibres, modifying their surface chemical composition and reactivity, and their génotoxicity (in acellular experiments). The fungi express anti-oxydant enzymes

Full textA quantitative procedure for landslide risk mapping has been developed considering hazard, vulnerability and exposed elements. The method is based on a susceptibility model previously developed from statistical relationships between past landslides occurred in the study area (last 50 years) and terrain parameters related to instability. Past landslide behaviour has been used to calculate landslide frequency for the future. An inventory of direct damage due to landslides during the study period was carried out and the main elements at risk in the area identified and mapped. Past monetary losses per type of element have been estimated and expressed as an average 'specific loss' for events of a given magnitude (corresponding to a specified scenario). Vulnerability has been assessed by comparing losses with the actual value of the elements affected and expressed as a fraction of that value (0-1).By integrating hazard, vulnerability and monetary value, direct landslide risk ( /pixel) has been computed for each element considered. Indirect losses from the disruption of economic activities due to landsliding have also been assessed. The final result is a risk map combining all losses per pixel for a 50-year period.

Full textThe intensification of extreme natural events, caused by climate change, together with strong urbanization, makes it essential for society to be prepared to cope with these emergency situations. The main priority after a natural event, that hit an anthropized area, is to save all human lives involved in the disaster. Subsequently, it will be necessary to restore a normal situation. Events such as floods, landslides and earthquakes generate a huge amount of debris and rubbles, creating numerous problems during emergency activities. To remedy this, it will be necessary to clean up the affected area as soon as possible, from this material. To ensure that the disaster waste management is efficient, it is necessary to have a protocol or at least a guideline to follow. In the world, a lot of protocols exist to manage the emergency situation after the natural event, but there is not enough information for the disaster waste management. This lack drives local authorities to use empirical management methods. The empirical method is based on experience in the field and does not take into account a scientific methodological approach, that analyses the environmental and economic impact generated by the disaster waste management. The guiding principles should be the reduction of the environmental footprint and of management costs; however, the emergency does not allow to carry out such analyses before choosing a strategy for the management of waste, due to the lack of time.

Full textThe conservation of natural protected areas (ANP) and their positioning as tools for conservation has been reflected in the regulations that establish the binding prior technical opinion (OTPV) as mandatory for a project that overlaps those areas, without its obtaining the proposed project is not viable. This procedure is known as compatibility. On the other hand, the creation of concerted scenarios in natural protected areas becomes important because it establishes the management of the territory and the resources that are in them, if such scenarios are carried out without the participation of the actors, they do not reflect the way that local populations are related to their environment. When these areas are located in the highlands, the probability that part of their actors are peasants communities is quite high, therefore the applicable rules are not only related to the ANP, but also those that recognize the rights of indigenous communities. In this sense, water plays an important role since it is a fundamental resource for the subsistence of these communities, as it not only allows them to access food through the cultivation of land or raising livestock, but it is also linked to a concept of territory, customs and collective identity. In addition, when water runs through an ANP the management established on the master plan becomes overriding for its uses, which may not coincide with the expectations and / or needs of the communities, so in this space applies laws that directly or indirectly regulate the resource use. Then, when the water source of a project is inside an ANP whose purpose is to guarantee the subsistence of a peasant community, the rules and regulations that are applied are those given by the ANA, SERNANP and MINAGRI due to the character of the project. However, before even thinking about the procedure to obtain a right to use water, the prior obligation is the OTPV (compatibility), this is the first step to execute the project, if it is not obtained, the project is not feasible and ends up being denied. This situation implies the tacit denial of the use of water to the community that requests it, thereby violating their human right to water and related rights as right to a dignified life and the rights of indigenous peoples In the present thesis, the case of peasant community of Aquia, located in Ancash, is analyzed to understand how the evaluation of SERNANP was accomplished, which did not consider the human right to water or the rights of indigenous peoples. Based on interviews with key actors, challenges were identified linked to evaluation of SERNANP both the DHA and the right of the communities. Once these challenges were determined, criteria could be established to carry out a differentiated evaluation in similar cases to peasant community of Aquia. In other words, additional technical criteria are proposed in the prior evaluation for delivering OTPV when one or more highland peasant communities are involved. Likewise, a legal analysis was carried out determining that the ratification of various international treaties associated with the DHA, are mandatory, which provide the legal basis to resolve and deliver the OTPV favorable to a project. This was complemented by the jurisprudence of the Inter-American Court of Human Rights (CIDH) and the United Nations Human Rights Court (CDHNU), which demonstrated that the mentions to Convention 169 and the rights of communities in the law of natural protected areas and the law of water resources, is the fundamental basis for evaluating compatibility requests considering the human right to water and the rights of communities.

Full textThe aim of this thesis is to study several aspects of risk measures particularly in the context of financial applications. The primary framework that we use is that of coherent risk measures as defined in Artzner et al (1999). But this is not the only class of risk measures that we study here. We also investigate the concepts of natural risk statistics Kou et al (2006) and convex risk measure Follmer/ and Schied (2002). The main contributions of this Thesis can be classified in three main axes: Capital allocation, risk measurement and capital requirement and solvency. In chapter 2, we characterize risk measures with the Lebesgue property on bounded càdlàg processes. This allows to present two applications in risk assessment and capital allocation. In chapter 3, we extend the concept of natural risk statistics to the space of infinite sequences. This has been done in order to introduce a consistent way of constructing risk measures for data bases of any size. In chapter 4, we discuss the concept of Good Deals and how to deal with a situation where these pathological positions are present in the market. Finally, in chapter 5, we try to relate all three chapters by extending the definition of Good Deals to a larger set of risk measures that somehow includes the discussions in chapters 2 and 3.
