Under severe seismic excitation, structural behavior of buildings and other constructions is highly complex. It involves, among other issues, soil-structure interaction, large strains and displacements, damage, plasticity, ...
The natural environment in which we live, is subjected, to a greater or lesser extent, to the pressure of human activity, with water being one of the most sensitive elements. For this reason, aware of this situation, from ...
There is a growing concern for protection and conservation of coastal ecosystems, which require a proper understanding of ecosystem dynamics and the ability to detect and predict changes in the ecosystem state. For this ...
The response of the climate systems to aerosols and their effect on the radiative budget of the Earth is the most uncertain climate feedback and one of the key topics in climate change mitigation. Air quality-climate studies ...
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 ...
This doctoral thesis presents the use of an opto-electronic system so-called OBR (Optical Backscattered Reflectometer) as an alternative of measurement in structural health monitoring (SHM) processes in concrete structures, ...
Planktonic cnidarians are those species or their stages in the phylum Cnidaria that spent their life in the water column and therefore, are tightly linked to oceanographic dynamics and water mass structures, such as fronts ...
Traditional sampling technologies such as trawling but also novel ones as ROV surveying are oriented toward a high spatial coverage without repeating data collection at fixed seabed windows. The temporal repetition is often ...
Explosive volcanic eruptions can eject large quantities of particulate matter that, along with other aerosol droplets and trace gases, are carried upwards into the atmosphere by the buoyant eruption column and then dispersed ...
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; ...
Coastal zones concentrate an elevated number of values both natural and socio-economic, making them very vulnerable to the potential effects of natural hazards. Therefore, effective risk management requires a holistic ...
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 ...
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 ...
The main objective of this thesis is the probabilistic assessment of the expected seismic damage in steel buildings located in Mexico City. Although a deterministic analysis is performed both, seismic actions and buildings, ...
Most of the microorganisms on Earth are found in sophisticated colonies called biofilms. Such microbial communities may proliferate everywhere life can exist as long as nutrients are available and surface attachment is ...
The concrete-steel composite slabs show a complex structural characterization due to the different behaviours at the two materials. The materials are exposed to different deformations, large deflections and complex stresses ...
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 ...
Nowadays, concrete pavements are one of the main traditional options of building roads and highways. Moreover, concrete pavements are used for various ground transport infrastructures such as sidewalks, streets and airport. ...
The development of high-speed train lines has increased significantly during the last twenty-five years, leading to more demanding loads in railway infrastructures. Most of these infrastructures were constructed using ...
The understanding of the driving forces involved in the abundance fluctuation of fish populations is an important requirement for conservation and management, especially in the context of environmental changes. In the North ...
