The oceans are microbial-dominated ecosystems, where protists (single-celled eukaryotes) play fundamental roles performing multiple functions as primary producers, consumers, decomposers as well as trophic linkers in aquatic ...
Sánchez Balseca, Joseph (Date of defense: 2021-11-15)
Air pollution is an environmental challenge that has an important influence on the life of human beings. Therefore, the development, implementation, and evaluation of new statistical approaches will improve the numerical ...
Pascual Torner, Maria (Date of defense: 2016-09-28)
Salps are marine pelagic tunicates that have evolved opportunistic skills to bloom under favorable conditions and persist during adverse periods. They experience population outbursts (blooms) which, combined with their ...
Lei, Jun (Date of defense: 2018-08-14)
During the construction and operation stages of structures, various factors lead to irreversible degradation that could affect the normal use and the public safety of these structures. In recent years, it has been common ...
Trubat Casal, Pau (Date of defense: 2020-03-12)
In the framework of the reduction of the emissions of greenhouse gases, FOWT will be the technology that will exploit the wind resources in deep seas. In order to achieve a commercial deployment of this technology, a cost ...
Solé Bundó, Maria (Date of defense: 2018-09-20)
Microalgae-based wastewater treatment systems are promising solutions to shift the paradigm from wastewater treatment to energy and resources recovery. In these systems, microalgae assimilate nutrients and produce oxygen ...
Segura Valdivieso, Guillermo (Date of defense: 2023-09-22)
(English) This thesis investigates the response of carbon and stainless steel frames in fire, and proposes new and more efficient approaches for their design. The investigation is mainly focused on one bay frames comprised ...
Ferrero, Chiara (Date of defense: 2021-07-20)
Since ancient times, master builders have used arches to cover large spans in masonry structures. As a consequence, nowadays the safety assessment of these structural elements plays a fundamental role in the conservation ...
González de León, Isabel (Date of defense: 2023-05-19)
(English) Stainless steel is one of the most promising construction materials due to its long service life, low maintenance requirements, excellent mechanical properties and high residual value. Nevertheless, for an efficient ...
Vitola Oyaga, Jaime (Date of defense: 2021-01-28)
For a few decades, systems for supervising structures have become increasingly irnportant. In origin, the strategies had as a goal only the detection of damages. Furthermore, now monitoring the civil or military structures ...
Makoond, Nirvan Chandra (Date of defense: 2020-12-16)
Many cultural heritage sites across the globe consist of masonry structures. To ensure the preservation of such structures, an accurate evaluation of their current structural condition is often of utmost importance. However, ...
Su, Hang (Date of defense: 2023-06-19)
(English) The steel-concrete composite structural solution has been widely applied in the execution of simply supported bridges since the merits of concrete compressive strength and steel tensile strength can be efficiently ...
Neagoe, Catalin Andrei (Date of defense: 2016-07-08)
La sostenibilidad de los edificios y de las infraestructuras públicas es un tema de importancia reciente puesto en discusión por la comunidad de ingeniería. La necesidad de diseñar estructuras con bajos requerimientos de ...
Peng, Tian (Date of defense: 2021-05-21)
Structure system identification (SSI) can be classified as static and dynamic depending on the type of excitation. SSI by Observability Method (OM) using static tests was proposed and analyzed to address the observability ...
Björk, Johannes (Date of defense: 2016-06-03)
Microbes form intricate and intimate relationships with most animals and plants, many of which are crucial for host development, health and functioning. Microbe--host symbiotic associations are poorly explored in comparison ...
Yang, Xuefei (Date of defense: 2021-07-06)
Textile wastewater often shows high color concentration, containing a large range of organic chemicals, with high chemical oxygen demand as well as hard-degradation materials. Therefore, understanding and developing effective ...
Eskenati, Amir Reza (Date of defense: 2023-06-09)
(English) The most common composite materials for strengthening building structures are divided into two dif ferent types based on the matrix’s composition, organics (polymers) or inorganics (cement, lime). The hybrid ...
Mao, Yanxin (Date of defense: 2018-09-06)
The hydro-mechanical behaviour of soils during freezing and thawing is a coupled multi-physics process that has important practical applications. To cite but a few examples, on artificial ground freezing –to provide ...
Espriu, Alexandra (Date of defense: 2017-07-17)
Nowadays nuclear power plants (NPP) and dedicated facilities are storing the spent nuclear fuel (SNF). In the case of Spain, the NPP have enough space in their pools to keep storing the SNF produced from their activity; ...
