De la Fuente Gamero, Patricia (Date of defense: 2019-10-04)
The Global Ocean is the largest Earth compartment holding carbon and nutrients that reaches the upper-ocean at temporal scales ranging from months to 10 kyr. The availability of these nutrients is fundamental to sustain ...
Carnerero Quintero, Cristina (Date of defense: 2021-09-30)
Atmospheric aerosol particles, particularly ultrafine particles (UFPs; particles with less than 100 nm in diameter), and tropospheric ozone (O3) are atmospheric pollutants highly influenced by photochemical reactions, i.e., ...
Albo-Puigserver, Marta (Date of defense: 2019-10-18)
Mediterranean marine ecosystems are fundamentally driven by their pelagic communities and small and medium-size pelagic fishes (SMPF) play crucial ecological roles. Although fluctuations of the populations of these organisms ...
Grinyó Andreu, Jordi (Date of defense: 2016-10-17)
Technological development and increased availability of remotely operated vehicles and manned submersibles have significantly increased accessibility to deep environments revealing the presence of rich and diverse macrobenthic ...
Corrales Ribas, Xavier (Date of defense: 2019-03-21)
Firstly, I reviewed modelling approaches that were used to assess the impact of invasive alien species (IAS) in aquatic ecosystems. According to the review, multispecies/ecosystem mechanistic models dominated the applications, ...
Pérez Madrigal, Domingo (Date of defense: 2018-06-20)
The use of bituminous material milled from the pavement (known as Reclaimed Asphalt Pavement, or RAP) in the manufacture of recycled bituminous mixtures is growing day by day due to the economic and environmental benefits ...
López Montero, Teresa (Date of defense: 2018-06-19)
Asphalt mixtures cracking is one of the most common deterioration mechanisms in flexible pavements. This phenomenon is due to both the application of loads and the degradation of the material as a result of its exposure ...
Mora Ortiz, René Sebastián (Date of defense: 2016-03-03)
The microstructure, understood as the distribution of pore sizes and their connectivity, is an important factor that affects the mechanical behaviour and the hydraulic properties of compacted soils with fine fraction (silts ...
Villarraga Díaz, Claudia Juliana (Date of defense: 2018-02-28)
The environmental conditions may play a relevant role in the stability of rock slopes. In fact, weathering can contribute to the reduction of strength of the material, while atmospheric actions may increase internal stresses ...
Marín Beltrán, Isabel (Date of defense: 2017-07-21)
The Mediterranean Sea is an oligotrophic basin, while the atmosphere above is affected by continuous emissions of anthropogenic aerosols and episodic Saharan dust events. These atmospheric inputs finally deposit (as wet ...
Titscher, Thomas (Date of defense: 2019-09-27)
Concrete is a complex material and can be modeled on various spatial and temporal scales. While simulations on coarse scales are practical for engineering applications, a deeper understanding of the material is gained on ...
Quaranta, Giacomo (Date of defense: 2019-09-02)
Numerical simulation, the use of computers to run a program which implements a mathematical model for a physical system, is an important part of today technological world. It is required in many scientific and engineering ...
Yubero de Mateo, Maria Teresa (Date of defense: 2021-07-22)
The urban tunneling may generate significant problems. One of the main concerns is the unavoidable ground movements generated; before, during and after the tunneling operations. In this context, the objective of this Thesis ...
Fernández González, Mario, 1970- (Date of defense: 2019-07-25)
This PhD thesis aims to analyse and verify the tense and intense relation that is established between the architecture, civil engineering and art worlds. Such analysis is conducted not only in a formal manner, but also at ...
Roca i Sans, Josep-Miquel (Date of defense: 2020-11-12)
This thesis aims to develop simple models that allow evaluating the relevance of the principal parameters that condition the energy flows in the ocean-atmosphere system, and how changes in these parameters impact the climate ...
Muñoz Liesa, Joan (Date of defense: 2022-07-20)
(English) Cities are great resource consumers and largely contribute to anthropogenic environmental impacts, urgently requiring a decarbonization plan. Urban agriculture lies on industrial ecology principles; waste resources ...
Bortolini, Rafaela (Date of defense: 2019-02-28)
The performance of existing buildings is receiving increased concern due to the need to renovate the aging building stock and provide better quality of life for end users. The conservation state of buildings and the indoor ...
Montemayor, Erica Yvonne (Date of defense: 2022-11-24)
(English) Agriculture not only contributes to more than a quarter of all global greenhouse gas emissions but is also the number one anthropogenic source of nitrogen emissions and a danger to nearly half of threatened ...
