Social development benefits of hydroelectricity CDM projects in Brazil

In recent years, the concept of sustainable development has become increasingly recognized and important. Within organizations, sustainable development is often portrayed as a balancing act, and requires a combination of three elements to be considered: economy, environment, and society. Traditionally, organizational management research has been focused on economical and environmental fronts. However, social aspects are also important for organizations, especially those in emerging and developing countries. The goal of this paper is to investigate the potential of Clean Development Mechanism (CDM) projects to deliver social benefits in Brazil?s hydroelectricity sector. The investigation involved the assessment of 46 registered hydro CDM projects under the Kyoto Protocol in terms of their potential impact on the envisaged social development goals. Two case studies were also examined. Results indicate that organizations managing hydroelectric initiatives in Brazil can provide the pathway towards achieving a number of important social benefits. Successful projects were found to have good community involvement and were managed by both cooperative ventures and money making corporations. The research also identified several challenges that are hindering hydro CDM projects from delivering more social benefits, and enabled a number of recommendations to be extracted for the organizations facing these challenges.

The human side of social technology for climate change mitigation and human development: the case of "efficient stoves" in Brazil

Carbon management has gradually gained attention within the overall environmental management and corporate social responsibility agendas. The clean development mechanism, from Kyoto Protocol, was envisioned as connecting carbon market and sustainable development objectives in developing countries. Previous research has shown that this potential is rarely being achieved. The paper explores how the incorporation of the human side into carbon management reinforces its contribution to generate human development in local communities and to improve the company's image. A case study of a Brazilian company is presented, with the results of the application of an analytical model that incorporates the human side and human development. The selected project is an "efficient stoves" programme. "Efficient stoves" are recognised in Brazil as social technologies. Results suggest that the fact that social technologies value the human side of the technology plays a key role when it comes to analysing the co-benefits of the project implementation.

Evaluation of Development Projects: a Process-Centered Approach in the Outskirts of Lima, Peru.

Development cooperation projects work with people involved in processes of change and social transformation. While the main objective of the intervention is the development process itself, the project?s quality will be determined by the way of implementing it. Its success lies in the sustainability of the generated processes and the connection with them by the involved actors. The evaluation analyses both aspects. This article examines the evaluation, under a process approach, of a project on urban agriculture in Lima (Peru). The results show that the use of this approach, which combines different evaluation tools, allows the identification and analysis of the processes with the involved members, providing a better understanding of the real sustainability of the results.

Evaluación de los co-beneficios sobre el desarrollo sostenible y la reducción de la pobreza de proyectos de mitigación del cambio climático en Brasil

El cambio climático y los diferentes aspectos del concepto de “desarrollo” están intrínsecamente interconectados. Por un lado, el desarrollo económico de nuestras sociedades ha contribuido a un aumento insostenible de las emisiones de gases de efecto invernadero, las cuales están desestabilizando el sistema climático global, generando al mismo tiempo una distribución desigual de la capacidad de las personas para hacer frente a estos cambios. Por otro lado, en la actualidad existe un amplio consenso sobre que el cambio climático impacta directamente y de manera negativa sobre el denominando desarrollo sostenible. De igual manera, cada vez existe un mayor consenso de que el cambio climático va a desafiar sustancialmente nuestra capacidad de erradicar la pobreza a medio y largo plazo. Ante esta realidad, no cabe duda de que las estrategias de adaptación son esenciales para mantener el desarrollo. Es por esto que hasta el momento, los mayores esfuerzos realizados por unir las agendas globales de la lucha contra la pobreza y del cambio climático se han dado en el entorno de la adaptación al cambio climático. Sin embargo, cada vez son más los actores que defienden, desde distintos escenarios, que existen sinergias entre la mitigación de emisiones y la mejora de las condiciones de vida de las poblaciones más vulnerables, favoreciendo así un “desarrollo sostenible” sin disminuir los recursos financieros destinados a la adaptación. Para hacer efectivo este potencial, es imprescindible identificar diseños de estrategias de mitigación que incrementen los resultados de desarrollo, contribuyendo al desarrollo sostenible al mismo tiempo que a reducir la pobreza. En este contexto se sitúa el objetivo principal de esta investigación, consistente en analizar los co-beneficios locales, para el desarrollo sostenible y la reducción la pobreza, de proyectos de mitigación del cambio climático que se implementan en Brasil. Por co-beneficios se entienden, en el lenguaje de las discusiones internacionales de cambio climático, aquellos beneficios que van más allá de la reducción de emisiones de Gases de Efecto Invernadero (GEI) intrínsecas por definición a los proyectos de mitigación. Los proyectos de mitigación más relevantes hasta el momento bajo el paraguas de la Convención Marco de las Naciones Unidas para el Cambio Climático (CMNUCC), son los denominados Mecanismos de Desarrollo Limpio (MDL) del Protocolo de Kioto. Sin embargo, existen alternativas de proyectos de mitigación (tales como los denominados “estándares adicionales” a los MDL de los Mercados Voluntarios de Carbono y las Tecnologías Sociales), que también serán tenidos en cuenta en el marco de este estudio. La elección del tema se justifica por la relevancia del mismo en un momento histórico en el que se está decidiendo el futuro del régimen climático a partir del año 2020. Aunque en el momento de redactar este documento, todavía no se ha acordado la forma que tendrán los futuros instrumentos de mitigación, sí que se sabe que los co-beneficios de estos instrumentos serán tan importantes, o incluso más, que las reducciones de GEI que generan. Esto se debe, principalmente, a las presiones realizadas en las negociaciones climáticas por parte de los países menos desarrollados, para los cuales el mayor incentivo de formar parte de dichas negociaciones se basa principalmente en estos potenciales co-beneficios. Los resultados de la tesis se estructuran alrededor de tres preguntas de investigación: ¿cómo están contribuyendo los MDL implementados en Brasil a generar co-beneficios que fomenten el desarrollo sostenible y reduzcan la pobreza?; ¿existen proyectos de mitigación en Brasil que por tener compromisos más exigentes en cuanto a su contribución al desarrollo sostenible y/o la reducción de la pobreza que los MDL estén siendo más eficientes que estos en relación a los co-beneficios que generan?; y ¿qué características de los proyectos de mitigación pueden resultar críticas para potenciar sus co-beneficios en las comunidades en las que se implementan? Para dar respuesta a estas preguntas, se ha desarrollado durante cuatro años una labor de investigación estructurada en varias fases y en la que se combinan diversas metodologías, que abarcan desde el desarrollo de un modelo de análisis de cobeneficios, hasta la aplicación del mismo tanto a nivel documental sobre 194 documentos de diseño de proyecto (denominado análisis ex-ante), como a través de 20 casos de estudio (denominado análisis ex-post). Con la realización de esta investigación, se ha confirmado que los requisitos existentes hasta el momento para registrar un proyecto como MDL bajo la CMNUCC no favorecen sustancialmente la generación de co-beneficios locales para las comunidades en las que se implementan. Adicionalmente, se han identificado prácticas y factores, que vinculadas a las actividades intrínsecas de los proyectos de mitigación, son efectivas para incrementar sus co-beneficios. Estas prácticas y factores podrán ser tenidas en cuenta tanto para mejorar los requisitos de los actuales proyectos MDL, como para apoyar la definición de los nuevos instrumentos climáticos. ABSTRACT Climate change and development are inextricably linked. On the one hand, the economic development of our societies has contributed to the unsustainable increase of Green House Gases emissions, which are destabilizing the global climate system while fostering an unequal distribution of people´s ability to cope with these changes. On the other hand, there is now a consensus that climate change directly impacts the so-called sustainable development. Likely, there is a growing agreement that climate change will substantially threaten our capacity to eradicate poverty in the medium and long term. Given this reality, there is no doubt that adaptation strategies are essentials to keep development. This is why, to date, much of the focus on poverty in the context of climate change has been on adaptation However, without diverting resources from adaptation, there may exist the potential to synergize efforts to mitigate emissions, contribute to sustainable development and reduce poverty. To fulfil this potential, it is key identifying how mitigation strategies can also support sustainable development and reduce poverty. In this context, the main purpose of this investigation is to explore the co-benefits, for sustainable development and for poverty reduction, of climate change mitigation projects being implemented in Brazil. In recent years the term co-benefits, has been used by policy makers and academics to refer the potentially large and diverse range of collateral benefits that can be associated with climate change mitigation policies in addition to the direct avoided climate impact benefits. The most relevant mitigation projects developed during the last years under the United Nations Framework Convention on Climate Change (UNFCCC) are the so-called Clean Development Mechanisms (CDM) of the Kyoto Protocol. Thus, this research will analyse this official mechanism. However, there are alternatives to the mitigation projects (such as the "add-on standards" of the Voluntary Carbon Markets, and the Social Technologies) that will also be assessed as part of the research. The selection of this research theme is justified because its relevance in a historic moment in which proposals for a future climate regime after 2020 are being negotiated. Although at the moment of writing this document, there is not a common understanding on the shape of the new mitigation instruments, there is a great agreement about the importance of the co-benefits of such instruments, which may be even more important for the Least Developed Countries that their expected greenhouse gases emissions reductions. The results of the thesis are structured around three research questions: how are the CDM projects being implemented in Brazil generating local co-benefits that foster sustainable development and poverty reduction?; are other mitigation projects in Brazil that due to their more stringent sustainable development and/o poverty reduction criteria, any more successful at delivering co-benefits than regular CDM projects?; and what are the distinguishing characteristics of mitigation projects that are successful at delivering co-benefits? To answer these research questions, during four years it has been developed a research work structured in several phases and combining various methodologies. Those methodologies cover from the development of a co-benefits assessment model, to the application of such model both to a desktop analysis of 194 project design documents, and to 20 case studies using field data based on site visits to the project sites. With the completion of this research, it has been confirmed that current requirements to register a CDM project under the UNFCCC not substantially favour co-benefits at the local level. In addition, some practices and factors enablers of co-benefits have been identified. These characteristics may be taken into consideration to improve the current CDM and to support the definition of the new international market mechanisms for climate mitigation.

Chinese energy and climate policies after Durban: save the Kyoto Protocol

Nowadays, one of the urgent issues regarding global climate change is to discuss the future of the second period of the Kyoto Protocol. However, the divergence of views and opinions among parties in the last Conference of the Parties of the United Nations Framework Convention on Climate Change, held in Durban in December 2011, is still large. One of the bones of contention is whether the emerging developing countries, like China, should make commitments and legally bind themselves to a Green House Gas (GHG) reduction target in near future. As the largest GHG emitting country, China and its energy and climate policies will play an important role in global climate change and will also significantly influence the other countries? policies and the global climate negotiation. In this paper, we review the current differences among parties in the Durban Conference, and we analyze the recent situation, barriers, and future policies in China. Finally we highlight the impact and potential effect of Clean Development Mechanisms in avoiding China?s barriers regarding climate change. Results show that China is making a great effort to mitigate climate change by establishing and reforming its energy and climate policies in order to achieve a low-carbon development. At the same time, more innovation and international collaboration is needed in China to achieve this goal.

Comportamiento estructural de tuberías forzadas y blindajes en saltos hidroeléctricos : propuestas de diseño y cálculo

En los últimos años ha aumentado el interés en el desarrollo de proyectos en el ámbito de las centrales hidroeléctricas y en concreto en las centrales reversibles. Estas centrales están diseñadas para grandes caudales y saltos, lo cual conlleva túneles de gran diámetro y alta presión y a menudo son esquemas subterráneos. Por ello, los estudios relativos a revestimientos de túneles en presión y los referentes a los blindajes de acero han cobrado una mayor relevancia. En las décadas de los 60 y 70 se realizó una importante labor de investigación coincidiendo con el desarrollo hidroeléctrico en Europa y Norteamérica, que sin embargo ha quedado sin continuidad hasta esta década, en la que se ha experimentado un impulso debido al desarrollo de nuevos proyectos hidroeléctricos de gran magnitud. La adecuación de los métodos de cálculo de blindajes supone una herramienta imprescindible en el correcto desarrollo técnico de los nuevos proyectos hidroeléctricos, así como para la evaluación de la seguridad de los saltos hidroeléctricos existentes en operación. En la presente Tesis se realiza un análisis del comportamiento estructural de las galerías en presión de saltos hidroeléctricos, así como una discusión y revisión de los métodos de cálculo existentes. En concreto se analizan los siguientes aspectos: •Descripción y comparación de las formulaciones existentes para el cálculo de blindajes tanto a presión exterior como interior. •Aplicación del Método de Elementos Finitos para la modelización y cálculo resistente y frente a inestabilidad de blindajes sometidos a presión exterior. •Análisis de un caso real, en el que se ha producido un fallo estructural en un blindaje sometido a presión exterior. Discusión sobre el comportamiento de blindajes con rigidizadores. Estudio paramétrico de la capacidad resistente y de la estabilidad de los blindajes con rigidizadores. •Estudio del comportamiento diferenciado entre un rigidizador y un conector. •Detalles constructivos y de durabilidad de las galerías en presión. •Desarrollo de una metodología para el cálculo de blindajes y tuberías forzadas a fatiga derivada de las variaciones de presión de la conducción. •Análisis de un caso real de una tubería forzada sometida a procesos de variación de carga, evaluando su seguridad frente a la fatiga. El cálculo de blindajes en galerías forzadas presenta una serie de aspectos complejos, y que no permiten la definición del problema con exactitud, tales como las características del macizo rocoso y su permeabilidad, la determinación del nivel freático, la holgura existente entre el blindaje y el revestimiento del trasdós y sus posibles defectos geométricos. Por estas incertidumbres, el cálculo de blindajes supone una materia compleja y que debe ser abordada desde la cautela y el análisis de otros trabajos y/o análisis realizados con anterioridad. En cualquier caso, debe realizarse un análisis de sensibilidad de los diversos parámetros que intervienen en el cálculo. En esta tesis se han descrito las principales formulaciones de cálculo de blindajes de galerías forzadas sometidas a presión interior y exterior; se ha constatado que existe una gran diversidad y que de su aplicación no se llega a resultados concluyentes. Las formulaciones clásicas utilizadas en el cálculo de blindajes lisos y con rigidizadores sometidos a presión exterior (Amstutz y Jacobsen) no resultan del todo adecuadas ni son de aplicación general. Además, pueden arrojar resultados no conservadores o conducir a un sobredimensionamiento del blindaje en otros casos. En las formulaciones tradicionales de diseño se han tenido en cuenta como imperfecciones la holgura del blindaje y la ovalidad del mismo. En la presente tesis, se han analizado imperfecciones de tipo ondulatorio derivadas de los procesos de soldadura y la existencia de espesores reducidos en zonas de corrosión. En el caso práctico analizado sometido a presión exterior, se ha comprobado el funcionamiento real del blindaje mediante los modelos realizados con elementos finitos. Se desprende que los rigidizadores no han funcionado como tales, puesto que para blindajes lisos se obtienen presiones más bajas de pandeo y para el caso de funcionamiento correcto de los rigidizadores se habría obtenido un coeficiente de seguridad suficiente. Por este motivo, se ha analizado el posible funcionamiento de los rigidizadores, que en determinados casos pueden actuar como conectores. En estos casos deben dimensionarse de forma adecuada las soldaduras para soportar las tensiones entre chapa y conector. Por otra parte, tradicionalmente no se han tenido en cuenta los efectos de fatiga que pueden ocasionar los golpes de ariete y las pulsaciones de presión debidas a la regulación secundaria de la red. En esta tesis se ha establecido un procedimiento de comprobación de tuberías forzadas y blindajes sometidos a procesos de fatiga. Adicionalmente, se ha estudiado el caso real de las tuberías forzadas de una central reversible real (Bolarque II) en funcionamiento de regulación secundaria. Se ha concluido, como en otros casos analizados en la bibliografía, que las pulsaciones derivadas de la regulación secundaria no son significativas como para tener en cuenta la fatiga del acero. Por otra parte, las maniobras de arranque y parada (golpe de ariete) suponen una variación importante de la presión en la conducción. Sin embargo, el moderado número de ciclos permite asegurar la integridad de la tubería frente a fenómenos de fatiga. Nowadays, there is a significant concern in the development of projects in the field of hydroelectric power plants, particularly in the pump-storage projects. These plants are designed for high flow rates and heads, which entails large-diameter tunnels and high pressure ratios), and often as underground schemes. Therefore, this concern has reactivated studies about penstocks and in particular those related to steel liners. During the 1960s and 1970s due to hydropower-engineering development in Europe and North America, a major research effort was done. However, the increasing development of new large-scale hydropower projects has involved a renewed research effort during this decade. The adequacy of steel liner calculation methods is a very important issue in the proper technical development of new hydroelectric projects, and for the safety assessment of existing hydroelectric power plants in operation. In this work, an analysis of the structural behavior of pressure galleries in hydroelectric schemes was carried out. Also, a discussion and a review of existing calculation methods are included. In particular, the following issues have been considered: •Description and comparison of existing formulations for calculating the liner response to both external and internal pressure. •Analysis of an actual case study of a steel liner which failed due to external pressure. •Application of the Finite Element Method to liner modeling and analysis subjected to external pressure. •A parametric study of the shielding with stiffeners and discussion about the behavior of liner with stiffeners. •Constructive aspects and durability of pressure galleries. •Development of a methodology for estimating fatigue effects on penstocks and liners sue to pressure changes. •Analysis of an actual case study of a penstock under varying load and assessment of its safety against fatigue. The project of a hydropower penstock is a complex issue, due to the uncertainties in the definition of the problem data, such as the characteristics of the rock mass and its permeability, the determination of the water table, the existing gap between the steel liner and the concrete of the backfill, the geometric imperfections... Hence, the design and analysis of a steel liner must be addressed cautiously and take into account a review of previous studies performed. Ever, a sensitivity analysis of the various parameters involved in the calculation should be performed. In this work, some of the most relevant formulations for liner design subjected to inside and outside pressure have been studied. As a whole, there is a wide variety and its application does not lead to conclusive results. The classical formulations used in the steel liner calculation either with or without stiffeners under external pressure (Amstutz and Jacobsen) are not entirely adequate Also, those can yield both conservative and non-conservative results in large ranges of application. Traditionally design approaches only considered initial gap and ovality as the most relevant geometric imperfections. Thus, little attention was paid to those caused either by welding or by thickness loss in corroded areas. In the case study analyzed in this thesis, the actual working of the liner under external pressure has been simulated by the Finite Element Method. Results show that the stiffeners have not performed as such, since for unstiffened liner lower buckling pressures are obtained and for proper performance of the stiffeners would give a sufficient safety factor. Hence, it must be pointed out that stiffeners may perform either as such or as connectors. For the latter, welding must be designed to properly withstand stresses between the shell and the stiffener. Likewise, the potential fatigue effects due to both water hammer and pressure pulsations due to secondary regulation of the network have not been considered in many studies. It has been included in this work a procedure for checking penstocks and liners under fatigue processes. Additionally, the penstock fatigue response of an actual pump storage project (Bolarque II, Spain) subjected to secondary control operation has been assessed. As in other cases discussed in the literature, pulsations derived from the secondary control are not significant to account for fatigue of steel. Moreover, the start and stop manoeuvres (water hammer) cause a significant change in penstock pressure. However, the moderate number of cycles ensures the integrity of the penstock against fatigue phenomena.

Evaluación de los Proyectos de Fin de Carrera realizados por estudiantes de la ETSI de Montes en las Universidades del SUNEO, México

Desde el año 2008 hasta finales de 2012 se han publicado dieciséis proyectos de fin de carrera realizados por alumnos de la Escuela Técnica de Ingenieros de Montes en tres de las escuelas del Sistema de Universidades Estatales de Oaxaca (SUNEO), México que se han analizado en este estudio. Los proyectos son muy diversos donde se profundizan temáticas muy distintas, pero todos tienen un fondo en común: la gestión del medio ambiente y el desarrollo de las comunidades indígenas oaxaqueñas. Sin embargo es necesario y siempre enriquecedor, saber qué ha pasado con posterioridad a la publicación de dichos proyectos, en qué han quedado los esfuerzos de los estudiantes hoy ingenieros y de ambas universidades implicadas, las del SUNEO por un lado como universidades receptoras que acogieron a los estudiantes que guiaron en el desarrollo de los proyectos, y por otro lado la Universidad Politécnica de Madrid, que formó a los ahora ingenieros y que les apoyó económicamente para realizar estos trabajos. Esta evaluación es un reto dada la diversidad de los proyectos y las distintas fechas en que fueron realizados. Algunos de ellos son de publicación reciente y apenas han empezado a dar sus frutos, pero es posible prever qué consecuencias van a tener si estudiamos las acciones que se están tomando actualmente para sacar el máximo provecho de toda la información generada en beneficio de las comunidades. Algunos proyectos son directamente y potencialmente ejecutables, otros (la mayoría) son de investigación, pero ellos no significa que no puedan tener efectos positivos sobre el entorno. Las formas de evaluar el efecto de proyectos ejecutados están ya muy estandarizadas, pero sin embargo no es así para los de investigación. Este documento tiene también como objeto dar pautas para poder evaluar este tipo de proyectos así como documentar las buenas prácticas y los factores de fracaso para aumentar la probabilidad de que estos trabajos alcancen el mayor impacto positivo posible en el futuro. From 2008 to the present many projects have been published by students from ETSI Montes UPM which were developed in three of the University Schools in the State University System of Oaxaca (SUNEO), Mexico. Until the end of 2012, sixteen projects had been published and these have been analyzed and included in this study. The projects are very diverse, and they all explore different themes but they all have a common background: environmental management and development of Oaxacan indigenous communities. However it is necessary to know what happened after the publication of such projects, and to observe the impact of them. It has been a joint effort between the two universities, on the one hand the SUNEO Universities which have received, hosted and guided the development of projects, and on the other hand the Polytechnic University of Madrid, who trained the current engineers and financed them to undertake these jobs. This evaluation is a challenge due to the diversity of the projects and the different dates on which they were carried out; some of them were recently published and are just beginning to bear fruit, but it is possible to predict what kind of impact they will produce if we study the actions currently being undertaken in order to take full advantage of all the information generated for the benefit of communities. Some projects are directly and potentially executable, others (the majority) are research works, but this does not mean they cannot have an impact. The way to evaluate the impact of technical projects is already very standardized, but there is not one for the research ones yet. This document will also give guidelines to assess the impacts of such projects and will also document good practices and actions to avoid in order to increase the likelihood that these projects achieve the greatest positive impact.

Modelado experimental de un sistema de e-Salud aplicado en cooperación al desarrollo

Los Objetivos de Desarrollo del Milenio comprometieron a los países con una nueva alianza mundial de alcanzar gradualmente una cobertura universal de los niveles mínimos de bienestar en los países en desarrollo (reducir la pobreza y el hambre y dar respuesta a problemas como la mala salud, las desigualdades de género, la falta de educación, el acceso a agua salubre y la degradación ambiental). Para dar continuidad a esta iniciativa, recientemente en septiembre de 2015, la ONU promulgó la declaración de los Objetivos de Desarrollo Sostenible. Los ODM sitúan la salud en el corazón del desarrollo y establecen un novedoso pacto mundial que vincula a los países desarrollados y los países en desarrollo por medio de obligaciones claras y recíprocas. En este sentido, diversos organismos de cooperación a través de sus programas de cooperación internacional, tratan de mejorar el acceso a la asistencia sanitaria, especialmente a la población vulnerable que vive en zonas rurales de países en desarrollo. Con el fin de ayudar a cumplir los ODM que apoyan los temas de salud en dicha población, estos organismos desarrollan proyectos que despliegan sistemas de e-salud. Las intervenciones se enfrentan a múltiples retos: condicionantes de los países en desarrollo, las necesidades y demandas de los sistemas sanitarios y la complejidad de implantar las TIC en entornos complejos y altamente dinámicos como son los países en desarrollo. Estos condicionantes ocasionan la mayoría de proyectos fallidos que terminan convirtiéndose en soluciones aisladas, que anteponen la tecnología a las necesidades de la población y no generan el impacto esperado en su desarrollo. En este contexto tuvo origen esta tesis doctoral, que persigue como objetivo analizar, planificar, diseñar, verificar y validar un marco arquitectónico de implantación de sistemas de e-salud en áreas rurales de países en desarrollo, que promueva el mejoramiento de la calidad de vida de la población vulnerable de estas regiones y la efectividad de las intervenciones de e-salud en el marco de proyectos de cooperación al desarrollo. Para lograrlo, tomé como punto de partida, diversas estrategias, modelos, metodologías de implantación de e-salud, modelos de gestión de proyectos propuestos por distintos organismos internacionales y propuse una instanciación de estos modelos a proyectos de implantación de sistemas de e-salud en países en desarrollo. Apliqué la metodología action research y los enfoques twin track, middle out y design thinking que me permitieron el refinamiento iterativo del modelo propuesto en la tesis doctoral mediante el trabajo de campo realizado en dos zonas rurales de países de Centroamérica: Jocotán (Guatemala) y San José de Cusmapa (Nicaragua). Como resultado obtuve un modelo experimental basado en cuatro componentes: un modelo de referencia tipo, un modelo conceptual de e-salud, los procesos de gestión y de implantación de sistemas de e-salud en países en desarrollo y una arquitectura de referencia. El modelo experimental resultante aporta herramientas importantes para el despliegue de sistemas de e-salud en países en desarrollo. Se ha propuesto un modelo de referencia que proporciona una visión holística del contexto del país en desarrollo donde se desarrollarán las intervenciones. Un modelo conceptual de e-salud que representa los principales conceptos involucrados en un sistema de e-salud. Los procesos ii- de gestión del proyecto y de implantación del sistema que proporcionan a los grupos de cooperación, herramientas para el análisis, diseño, desarrollo y despliegue de los sistemas de e-salud en áreas rurales de países en desarrollo. Y finalmente la arquitectura de referencia que sienta las bases para la aplicación de estos procesos a un contexto en particular. Las líneas futuras de trabajo sugieren extender el modelo a más casos de estudio que permitan su refinamiento y evaluar los futuros usos que pueden surgir de los sistemas de e-salud resultantes. ABSTRACT Millennium Development Goals (MDGs) committing the countries with a new global partnership to achieve universal coverage of minimum levels of well-being in Developing Countries (for addressing extreme poverty in its many dimensions-income poverty, hunger, disease, lack of adequate housing, and exclusion-while promoting gender equality, education, and environmental sustainability). From September 2015, these goals are replaces with Sustainable Development Goals (SDGs). The MDG place health at the heart of development and establish a novel global compact, linking developed and developing countries through clear, reciprocal obligations. Many public and private institutions promote international cooperation programs to support in achieving the MDGs. Some of these cooperation programs deal improving access to healthcare to poor people living in isolated areas from developing countries. In order to accomplish this goal organizations perform projects (interventions or cooperation projects) that deploy e-health systems in these zones. Nevertheless, this kind of projects face multiple challenges that dismiss the effectiveness of the projects results. In particular, cooperation teams face issues such as constraints in developing countries, lack of electrical and ICT infrastructure, scarce transport, extreme climate conditions, lack ICT capacity, lack of access to healthcare and inefficient delivery methods, etc. Hence, these issues increase the complexity of implementing e-health in developing countries and then causes the most projects fail. In other words, the solutions do not meet population needs and do not generate the expected impact on development. This context is the starting point of this doctoral thesis, which deals with analysing, planning, designing, testing and validating an architectural framework in order to implement e-health systems in rural areas from developing countries, promote development of the population in these regions, and thus improve the impact of interventions of development cooperation projects. To achieve this goal, I took as a starting point the strategies, models, e-health implementation methodologies and projects management models proposed by various international agencies. Then I proposed an instantiation of these models to manage the intervention and implement e-health systems in developing countries. I applied the action research methodology and the approaches twin track, middle out and design thinking which allowed me the iterative refinement of the model proposed in this doctoral thesis. The proposed framework was validated by running two cases studies in rural areas of Central America: Jocotán (Guatemala) and San José de Cusmapa (Nicaragua). As a result, I obtained an experimental model based on four components: a Type reference model, an e-health conceptual model, both process management and implementation e-health systems in developing countries and a reference architecture. The resulting experimental model provides important tools for the deployment of e-health systems in developing countries. The model become as reference model that provides a holistic view of the developing countries context where the interventions will be running. The conceptual model of e-health represents the main concepts involved into an e-health system. The project management and implementation processes of the iv- system provide to the cooperation teams with tools for analysing, designing, developing and deploying e-health systems in rural areas from developing countries. Finally, the reference architecture provides the basis for the implementation of these processes into a particular context. The future research suggest the extension the model to other cases studies in order to refine and evaluate the viability the model.

Análisis espectral de señales cardiacas mediante frecuencia dominante

La Ingeniería Biomédica surgió en la década de 1950 como una fascinante mezcla interdisciplinaria, en la cual la ingeniería, la biología y la medicina aunaban esfuerzos para analizar y comprender distintas enfermedades. Las señales existentes en este área deben ser analizadas e interpretadas, más allá de las capacidades limitadas de la simple vista y la experiencia humana. Aquí es donde el procesamiento digital de la señal se postula como una herramienta indispensable para extraer la información relevante oculta en dichas señales. La electrocardiografía fue una de las primeras áreas en las que se aplicó el procesado digital de señales hace más de 50 años. Las señales electrocardiográficas continúan siendo, a día de hoy, objeto de estudio por parte de cardiólogos e ingenieros. En esta área, las técnicas de procesamiento de señal han ayudado a encontrar información oculta a simple vista que ha cambiado la forma de tratar ciertas enfermedades que fueron ya diagnosticadas previamente. Desde entonces, se han desarrollado numerosas técnicas de procesado de señales electrocardiográficas, pudiéndose resumir estas en tres grandes categorías: análisis tiempo-frecuencia, análisis de organización espacio-temporal y separación de la actividad atrial del ruido y las interferencias. Este proyecto se enmarca dentro de la primera categoría, análisis tiempo-frecuencia, y en concreto dentro de lo que se conoce como análisis de frecuencia dominante, la cual se va a aplicar al análisis de señales de fibrilación auricular. El proyecto incluye una parte teórica de análisis y desarrollo de algoritmos de procesado de señal, y una parte práctica, de programación y simulación con Matlab. Matlab es una de las herramientas fundamentales para el procesamiento digital de señales por ordenador, la cual presenta importantes funciones y utilidades para el desarrollo de proyectos en este campo. Por ello, se ha elegido dicho software como herramienta para la implementación del proyecto. ABSTRACT. Biomedical Engineering emerged in the 1950s as a fascinating interdisciplinary blend, in which engineering, biology and medicine pooled efforts to analyze and understand different diseases. Existing signals in this area should be analyzed and interpreted, beyond the limited capabilities of the naked eye and the human experience. This is where the digital signal processing is postulated as an indispensable tool to extract the relevant information hidden in these signals. Electrocardiography was one of the first areas where digital signal processing was applied over 50 years ago. Electrocardiographic signals remain, even today, the subject of close study by cardiologists and engineers. In this area, signal processing techniques have helped to find hidden information that has changed the way of treating certain diseases that were already previously diagnosed. Since then, numerous techniques have been developed for processing electrocardiographic signals. These methods can be summarized into three categories: time-frequency analysis, analysis of spatio-temporal organization and separation of atrial activity from noise and interferences. This project belongs to the first category, time-frequency analysis, and specifically to what is known as dominant frequency analysis, which is one of the fundamental tools applied in the analysis of atrial fibrillation signals. The project includes a theoretical part, related to the analysis and development of signal processing algorithms, and a practical part, related to programming and simulation using Matlab. Matlab is one of the fundamental tools for digital signal processing, presenting significant functions and advantages for the development of projects in this field. Therefore, we have chosen this software as a tool for project implementation.

Clean Coal Technologies Scenario and Evaluation of Present CO2 Dwindling Initiatives to Approach Zero Emission Power Stations By Coal Combustion. Deployment Situation and Evaluation Study

In the present uncertain global context of reaching an equal social stability and steady thriving economy, power demand expected to grow and global electricity generation could nearly double from 2005 to 2030. Fossil fuels will remain a significant contribution on this energy mix up to 2050, with an expected part of around 70% of global and ca. 60% of European electricity generation. Coal will remain a key player. Hence, a direct effect on the considered CO2 emissions business-as-usual scenario is expected, forecasting three times the present CO2 concentration values up to 1,200ppm by the end of this century. Kyoto protocol was the first approach to take global responsibility onto CO2 emissions monitoring and cap targets by 2012 with reference to 1990. Some of principal CO2emitters did not ratify the reduction targets. Although USA and China spur are taking its own actions and parallel reduction measures. More efficient combustion processes comprising less fuel consuming, a significant contribution from the electricity generation sector to a CO2 dwindling concentration levels, might not be sufficient. Carbon Capture and Storage (CCS) technologies have started to gain more importance from the beginning of the decade, with research and funds coming out to drive its come in useful. After first researching projects and initial scale testing, three principal capture processes came out available today with first figures showing up to 90% CO2 removal by its standard applications in coal fired power stations. Regarding last part of CO2 reduction chain, two options could be considered worthy, reusing (EOR & EGR) and storage. The study evaluates the state of the CO2 capture technology development, availability and investment cost of the different technologies, with few operation cost analysis possible at the time. Main findings and the abatement potential for coal applications are presented. DOE, NETL, MIT, European universities and research institutions, key technology enterprises and utilities, and key technology suppliers are the main sources of this study. A vision of the technology deployment is presented.

Capacity building in development projects

Development projects of different types mainly aim to alleviate poverty and ameliorate the livelihoods of local people. One of the strategies commonly used is to focus on organizations and build from their existing capacities in order to improve their living standards or try to build new organizations to work in a common project. Social and human capitals are two key components of these organizations and they might be crucial to the success of the actions that they accomplish. Both can be considered as part of the social capacity of the local organization. This capacity can be enforced with development projects through capacity building. This term means much more than training activities as it includes not only human resource development but also organizational and institutional development (UNESCO, 2010). Capacity and capacity building concepts, as well as capacity measurements in this context are explored to build a framework to evaluate the social capacity generated with the interventions and better plan the actions to be undertaken by the projects to succeed. The focus is set on rural development projects.

Jasmonate-dependent modifications of the pectin matrix during potato development function as a defense mechanism targeted by Dickeya dadantii virulence factors

The plant cell wall constitutes an essential protection barrier against pathogen attack. In addition, cell-wall disruption leads to accumulation of jasmonates (JAs), which are key signaling molecules for activation of plant inducible defense responses. However, whether JAs in return modulate the cell-wall composition to reinforce this defensive barrier remains unknown. The enzyme 13-allene oxide synthase (13-AOS) catalyzes the first committed step towards biosynthesis of JAs. In potato (Solanum tuberosum), there are two putative St13-AOS genes, which we show here to be differentially induced upon wounding. We also determine that both genes complement an Arabidopsis aos null mutant, indicating that they encode functional 13-AOS enzymes. Indeed, transgenic potato plants lacking both St13-AOS genes (CoAOS1/2 lines) exhibited a significant reduction of JAs, a concomitant decrease in wound-responsive gene activation, and an increased severity of soft rot disease symptoms caused by Dickeya dadantii. Intriguingly, a hypovirulent D. dadantii pel strain lacking the five major pectate lyases, which causes limited tissue maceration on wild-type plants, regained infectivity in CoAOS1/2 plants. In line with this, we found differences in pectin methyl esterase activity and cell-wall pectin composition between wild-type and CoAOS1/2 plants. Importantly, wild-type plants had pectins with a lower degree of methyl esterification, which are the substrates of the pectate lyases mutated in the pel strain. These results suggest that, during development of potato plants, JAs mediate modification of the pectin matrix to form a defensive barrier that is counteracted by pectinolytic virulence factors from D. dadantii.

Usability-Oriented Software Development Process

Usability is the capability of the software product to be understood, learned, used and attractive to the user, when used under specified conditions. Many studies demonstrate the benefits of usability, yet to this day software products continue to exhibit consistently low levels of this quality attribute. Furthermore, poor usability in software systems contributes largely to software failing in actual use. One of the main disciplines involved in usability is that of Human-Computer Interaction (HCI). Over the past two decades the HCI community has proposed specific features that should be present in applications to improve their usability, yet incorporating them into software continues to be far from trivial for software developers. These difficulties are due to multiple factors, including the high level of abstraction at which these HCI recommendations are made and how far removed they are from actual software implementation. In order to bridge this gap, the Software Engineering community has long proposed software design solutions to help developers include usability features into software, however, the problem remains an open research question. This doctoral thesis addresses the problem of helping software developers include specific usability features into their applications by providing them with a structured and tangible guidance in the form of a process, which we have termed the Usability-Oriented Software Development Process. This process is supported by a set of Software Usability Guidelines that help developers to incorporate a set of eleven usability features with high impact on software design. After developing the Usability-oriented Software Development Process and the Software Usability Guidelines, they have been validated across multiple academic projects and proven to help software developers to include such usability features into their software applications. In doing so, their use significantly reduced development time and improved the quality of the resulting designs of these projects. Furthermore, in this work we propose a software tool to automate the application of the proposed process. In sum, this work contributes to the integration of the Software Engineering and HCI disciplines providing a framework that helps software developers to create usable applications in an efficient way.

Comparison of CO2 From Coal Capture Processes and Valorisation Technologies

Coal is the most plentiful and evenly distributed fossil fuel worldwide. Based on current production, it is estimated that the reserves will last approximately 130 years. Its use worldwide has been increasing, mainly due to consumption by emerging countries. CO2 emissions generated by combustion and the repercussions of such on climate change support the view that it could no longer be used. CO2 capture may be the solution to continue using it, which would cater for the growing energy demand worldwide. The aim of this study is to compare different processes concerning CO2 capture that may be economically viable, ultimately showing that coal, a fossil energy source widely distributed around the world, can, as a result of using different CO2 capture processes, be used as a clean source of electricity. Hence, in places where geological hurdles may render the costs of CO2 storage considerably higher, since it might have to travel far, coal may be used for other purposes, thus valorising CO2 within the industrial sector. This research is focused on the technical and economic comparison of the most relevant CO2 capture projects designed in Spain using different existing technologies. The oxyfuel project in Ciuden (Leon, Spain), the IGCC Elcogas, precombustion CO2-capture project (Puertollano, Spain) and the postcombustion project in Carboneras (Almeria, Spain) will be analyzed in order to assess the options available to valorise captured CO2. Valorising captured CO2 may be an adequate solution in areas where, although CO2 capture is still possible, storage is not equally so, thus generating a further benefit. The possible uses of CO2 will be assessed in vegetable growing greenhouses, harnessing CO2 in vegetable life cycles. This will also be used in growing algae for subsequent biodiesel production. Both CO2 capture and valorising will eventually lead to the clean use of coal, which will thus enhance the level of self-supply, aiding the development of electric vehicles, which require large amounts of electricity, as well as improve the level of energy autonomy in countries around the world. Another type of fuel, biodiesel, will also be obtained, without this affecting international food prices.

Assessment of Hydrogen as suistinable clean energy

The progressive depletion of fossil fuels and their high contribution to the energy supply in this modern society forces that will be soon replaced by renewable fuels. But the dispersion and alternation of renewable energy production also undertake to reduce their costs to use as energy storage and hydrogen carrier. It is necessary to develop technologies for hydrogen production from all renewable energy storage technologies and the development of energy production from hydrogen fuel cells and cogeneration and tri generation systems. In order to propel this technological development discussed where the hydrogen plays a key role as energy storage and renewable energy, the National Centre of Hydrogen and Fuel Cell Technology Experimentation in Spain equipped with installations that enable scientific and technological design, develop, verify, certify, approve, test, measure and, more importantly, the facility ensures continuous operation for 24 hours a day, 365 days year. At the same time, the system is scalable so as to allow continuous adaptation of new technologies are developed and incorporated into the assembly to verify integration at the same time it checks the validity of their development. The transformation sector can be said to be the heart of the system, because without neglecting the other sectors, this should prove the validity of hydrogen as a carrier - energy storage are important efforts that have to do to demonstrate the suitability of fuel cells or internal combustion systems to realize the energy stored in hydrogen at prices competitive with conventional systems. The multiple roles to meet the fuel cells under different conditions of operation require to cover their operating conditions, many different sizes and applications. The fourth area focuses on integration is an essential complement within the installation. We must integrate not only the electricity produced, but also hydrogen is used and the heat generated in the process of using hydrogen energy. The energy management in its three forms: hydrogen chemical, electrical and thermal integration requires complicated and require a logic and artificial intelligence extremes to ensure maximum energy efficiency at the same time optimum utilization is achieved. Verification of the development and approval in the entire production system and, ultimately, as a demonstrator set to facilitate the simultaneous evolution of production technology, storage and distribution of hydrogen fuel cells has been assessed.
