Gonzalez‐Blanco, Laura (Date of defense: 2017-05-31)
Deep geological disposal remains the preferred option at present for the management of long-living and heat-emitting radioactive waste, which consists of confining the waste during a very long period (several hundreds of ...
Labarre, Aurélie (Date of defense: 2020-11-26)
In the vast network of the ocean, microbes are abundant and unevenly distributed. As an important microbial component, the protists play a key role in global biogeochemical cycles and contribute to the recycling of nutrients ...
Dávila Ordóñez, Maria Gabriela (Date of defense: 2015-11-06)
A test site for CO2 geological storage is situated in Hontomín (Burgos, northern Spain) with a reservoir rock that is mainly composed of limestone. The reservoir rock is a deep saline aquifer, which contains a NaCl- and ...
Shen, Yanfei (Date of defense: 2019-12-02)
In AISC 360-16, the Direct Analysis Method (DM) has been set as the primary method for the stability design of frames. DM, considering initial global sway imperfection, is essentially Geometrically Non-linear Analysis (GNA) ...
García Alcaraz, María del Mar (Date of defense: 2016-03-04)
This thesis promotes an efficient use of shallow geothermal energy by means of an integrated management system to organize its exploitation. Shallow geothermal energy is a renewable resource based on thermal energy exchange ...
Torres Serra, Joel (Date of defense: 2021-02-26)
In the packaging industry, a wide range of powders and bulk solids are handled in bagging equipment using different bulk feeding techniques. Quality of the packaging is critically affected by feeder performance, which is ...
Castro, Lucas Vassalle de (Date of defense: 2021-07-05)
This PhD thesis aimed at evaluating the performance of high rate algal ponds (HRAP) to post-treat the anaerobic effluent from an upflow anaerobic sludge blanket (UASB) reactor fed with sewage. The work analysed the system ...
Borchini, Luca (Date of defense: 2020-12-17)
Nowadays, the main computational bottleneck in computer-assisted industrial design procedures is the necessity of testing multiple parameter settings for the same problem. Material properties, boundary conditions or ...
Pallarès López, Elena (Date of defense: 2016-07-25)
It is widely known that wind and wave predictions in the nearshore are less precise for semi enclosed domains than in the open ocean. The Catalan coast is a clear example of this situation, with a wave climate controlled ...
Alacid Fernández, Elisabet (Date of defense: 2017-07-18)
Parasitism is a widespread interaction that has evolved practically in all branches of the tree of life. It has historically been neglected in studies of marine microbial systems, limiting our understanding of marine food ...
Ribera Pi, Judit (Date of defense: 2019-07-23)
The increasing water demand coupled to the depletion of natural water sources has raised the need to investigate and develop in wastewater treatment and reuse. Even more, the application of circular economy principies to ...
Tarragó Munté, Daniel (Date of defense: 2021-06-03)
The starting point of this thesis is the failure of part of a quay wall under construction. The quay was divided in two phases, failure affected Phase 1 only. The failure and all the relevant associated information on quay ...
Ruiz Restrepo, Daniel Felipe (Date of defense: 2020-06-12)
Bentonite-based materials are being currently considered in several countries as a backfill component in the multi-barrier concept for deep geological disposal of radioactive waste. The bentonite barrier fulfils several ...
Mirsalehi, Sajjad (Date of defense: 2018-04-30)
This research focusses on an experimental investigation on the hydro-mechanical behaviour of binary ‘all-one’ mixtures. These mixtures –originated from the excavation of selected materials during earthwork constructions– ...
Mesa Alcantara, Arisleidy (Date of defense: 2021-07-02)
The hydro-mechanical behaviour of MX80 bentonite pellet-based mixture (80% high-density pellets in dry mass and crushed granular powder) has been explored in this thesis within the context of the French ‘Vertical Sealing ...
Trabucchi, Michela (Date of defense: 2021-05-11)
The characterization of evaporitic aquifers for a better understanding of hydrodynamics and geochemical processes is of great importance, especially in environments where both the sustainability of unique ecosystems and ...
Serrano Juan, Alejandro (Date of defense: 2016-07-22)
The competition for space in urban areas due to an exponential growth of population makes derground engineering plays a crucial role in the development of cities. Urban underground infrastructures deal with variables such ...
Marazuela Calvo, Miguel Ángel (Date of defense: 2020-07-03)
This thesis aims to advance the knowledge of the hydrogeological functioning of salt flats in order to achieve a sustainable management of their mineral resources and ecosystems. Salt flats are a major source of Li, B, I, ...
Rorato, Riccardo (Date of defense: 2019-11-08)
The shape of particles is known to play an important role in soil behaviour, with significant effects of engineering responses. Investigating how the shape of particles can be measured and quantified is therefore considered ...
Gaspar i Fàbregas, Kàtia (Date of defense: 2018-06-27)
Bridging the gap between the predicted and actual energy performance of buildings is necessary to increase the energy performance of existing buildings and achieve the European Union’s energy efficiency targets in the “2030 ...
