Water and clean energy services in developing countries: Regulation and evaluation of universal service policies
In this thesis I analyze access problems to basic services like water and energy in developing countries. The objective of the thesis is to show how to improve access to water services and clean energies in rural communities ...
Water buffalo microbiota and immunity during infectious diseases
La tesi té com a objectiu investigar la resposta immune dels búfals d’aigua (Bubalus bubalis) durant malalties infeccioses (per exemple, mastitis, brucel·losi i tuberculosi) i malalties de produccions, com malalties ...
Water flows to multiple stsakeholders: an ecosystem services-based approach to conflicts in the Ter River basim
Els conflictes relacionats amb la gestió dels cabals han sigut objecte d’abundant estudi. Tanmateix, manquen anàlisis que considerin l’apropiació d’aquells serveis ecosistèmics (SE) que depenen dels cabals circulants. Tal ...
Water mass variability in the eastern South Pacific and the ventilation of the oxygen minimum zone
This dissertation aims at extending our knowledge of the ESP OMZ through two main approaches. The first approach is based on tracer analysis and inverse modeling techniques. Such techniques are applied to hydrographic ...
Water oxidation with mononuclear ru complexes. Below the tip of the iceberg: the oxo-bridge scenario
La conversión de la energía solar en combustibles limpios como el H2 o el MeOH representa uno de los candidatos más prometedores para la sustitución de fuentes de energía basadas en combustibles fósiles. Las celdas solares ...
Water pollution, cancer and molecular mechanisms
Disinfection by-products (DBP) are complex mixtures of toxicants derived from drinking water treatment. Trihalomethanes (THM) and haloacetic acids (HAA) are the most prevalent DBP in chlorinated waters, which are used as ...
Water resources assessment in cold regions: the Upper Tuul River basin, Mongolia
Groundwater withdrawals are growing in most developing countries, including Mongolia, where freshwater resources are limited and unevenly distributed, and most surface waters are frozen during winter. Groundwater represents ...
Water service delivery solutions in rural and peri-urban areas in developing countries : are public-public partnerships a valuable alternative to private sector participation?
This dissertation will focus on the analysis of water and sanitation service delivery solutions in the context of peri-urban and rural areas. In particular, it will investigate if public-public partnerships (PuPs) can ...
Water Splitting Electrocatalysts in Acidic Media: in the Search of Non-noble Metal Alternatives
L'electròlisi de membrana d'intercanvi de protons (PEM) és una tecnologia comercialment madura i sostenible per a la producció d'hidrogen en àcid, però la manca de materials basats en metalls no nobles tant a l'ànode com ...
Water stress measurements in fruit trees under different regulated deficit irrigation regimes
L'aplicació de Reg Deficitari Controlat (RDC) en parcel·les comercials d'arbres fruiters s'enfronta a una<br/>problemàtica variada. En primer lloc cal buscar una metodologia fiable que permeti caracteritzar l'estrès<br/>en ...
Water use patterns and physiological interactions in Submediterranean mixed forests: methodological challenges and implications for ecohydrology
En aquesta tesi hem estudiat el comportament fisiològic i els patrons de l’ús de l’aigua en relació a la sequera en pins i roures submediterranis, tant en experiments de laboratori com en condicions de camp. El nostre ...
The water-energy-food nexus to tackle climate change in Morocco
The water, energy and food nexus is a theoretical approach to better understand and systematically examine the interactions between the natural environment and human activities, and to work towards a more organized management ...
Water-in-Water Emulsions for Obtaining Enzyme-Loaded Microgels and Encapsulated Emulsions
Encapsulation of enzymes into protective matrices is of interest in drug delivery or industrial processes, to control the release of the enzyme or protect it from harsh environments. We are studying the encapsulation of ...
Wave propagation in metamaterials mimicking spacetime geometry: black holes and cosmic strings
In physics, it is common to find different phenomena being described by similar equations. A good analogy can make us look at a problem from a different point of view. In that way, ideas may be transferred from one field ...
Wave propagation problems with aeroacoustic applications
The present work is a compilation of the research produced in the field of wave propagation modeling. It contains in-depth analysis of stability, convergence, dispersion and dissipation of spatial, temporal and spatial-temporal ...
Waveform modelling of binary black holes in the advanced ligo era
[eng] The focus of this thesis is the development of accurate and computationally efficient waveform models for the description of the signal of non-precessing and precessing blackhole binary systems detected by the ...
Wavelet approach in computational finance
En el món de les finances computacionals, tant els preus de derivats com la gestió de riscos han atret molt d'interès entre els professionals i l'acadèmia. Aquesta tesi pretén proporcionar tècniques basades en ondetes a ...
Wavelet-based spatial audio framework : from ambisonics to wavelets: a novel approach to spatial audio
Ambisonics is a complete theory for spatial audio whose building blocks are the spherical harmonics. Some of the drawbacks of low order Ambisonics, like poor source directivity and small sweet-spot, are directly related ...
Waves and turbulence on submerged and emergent aquatic vegetation
Coastal zones are governed by physical forces originating from tidal currents, waves, winds and night convection, amongst others, and are characterized by the presence of canopy meadows. This thesis studies the hydrodynamic ...
Wàsi, ver entre los Iku. Etnografía de las Imágenes en la Sierra Nevada de Santa Marta, Colombia
La Sierra Nevada de Santa Marta de Colombia, ha estado amenazada por el conflicto armado, proyectos de desarrollo, explotación de hidrocarburos, minería, narcotráfico y turismo, poniendo en riesgo la sobrevivencia de los ...
