Railway bridges located at seismic zones are particularly complex structures that present exceptional difficulties due to the existence of the track and the phenomena associated to it called track-bridge interaction. The ...
Water is undoubtedly the most essential resource of humanity. However. supplying the human population with clean water has been a major challenge for decades. Contaminants in wastewaters endanger water bodies and the ...
The efficient and equitable use of urban road space considered as a public good and a scarce resource, leads to giving priority to sustainable transport modes (walking, cycling and public transport). Private vehicle sees ...
This thesis presents the study of the model order reduction for power grids and transmission networks. The specific focus has been the transient dynamics. A mathematical viewpoint has been adopted for model reduction. Power ...
The use of externally bonded fibre reinforced polymers, FRP, for strengthening reinforced concrete (RC) beams or columns is an alternative to other traditional strengthening techniques due to its high strength-to-weight ...
This thesis develops a new structural strengthening technique: converting existing reinforced concrete structures to composite sections by inserting connectors after controlled demolition with high-pressure water. The key ...
Persistent organic pollutants (POPs) constitute an heterogeneous group of chemical substances of great environmental relevance. Its persistence, bioaccumulation, long-range transport potential and negative effects on health ...
European sea bass (Dicentrarchus labrax) aquaculture is a thriving industry in Spain where it reached about 23,500 t and a market value of approximately 133 million euros. However, most of the sea bass farms produce a high ...
The upper ocean circulation is the area of confluence of two major vertical cells: the large-scale overturning Atlantic Meridional Overturning Circulation (AMOC) and the regional relatively shallow Subtropical Cells (STCs). ...
(English) Marine heterotrophic flagellates (HF) are very small (2-5 µm) unpigmented protists that are dominant bacterial grazers in the ocean, where they link the transfer of carbon from bacterial cells to higher trophic ...
Infrastructure maintenance programs establish schedules for routine inspections of highway bridges with little consideration of their current conditions. The time interval between two inspections is traditionally set based ...
The present thesis aims at the analysis of the fragmentation of rockfalls. The fragmentation is a complex phenomenon poorly understood with a lack of tools to reproduce it on rockfall simulators. The effect of fragmentation ...
This thesis aims to assess the effects of the complex mixture of organic pollutants on the Prochlorococcus photosynthetic capability, in field, and at sublethal level, in the multifactorial context of the global change. ...
The potential capacity of fertilization of surface oceans by atmospheric deposition is of scientific interest. This is especially true in the oligotrophic Mediterranean Sea. Its surface waters are extremely poor in nutrients ...
Arctic sea ice plays a central role in the Earth’s climate. Changes in the sea ice on seasonal-to-interannual timescales impact ecosystems, populations and a growing number of stakeholders. A prerequisite for achieving ...
Freshwater quality and availability in coastal areas are affected by seawater intrusion into coastal aquifers. While coastal water quality and coastal ecosystems can be significantly affected by pollutants discharged into ...
The design rules on Reduced Beam Sections (RBS) are covered in the Eurocodes in EN1998-3 as a possible solution to improve rotation capacity of beams for the retrofit of existing structures. The design rules are very similar ...
As one of the main historical construction materials, masonry is abundant among the architectural heritage of earthquake-prone areas of the Mediterranean countries. Earthquake mitigation approaches are now focusing on ...
The seismic vulnerability of urban assets exposed to earthquake hazard represents a growing concern in the engineering field due to the potential risk of collapse for the buildings, and the associated devastating consequences ...
This thesis aimed to explore the potential of Se/Zn-enriched bioproducts produced from wastewater treatment processes by eco-technologies (phytoextraction, bioreduction and microalgae-based systems) as Se/Zn feed supplements ...
