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 ...
(English) The objective of this research is to delve into the decision-making processes that shape the provision of transport infrastructure. To this end, it analyses the historical evolution of transport networks in ...
Numerical simulation tools are generally used in all modern engineering fields, especially those having difficulties in performing large number of practical experiments, such as biomechanics. Among the computational methods, ...
Traditional design procedures of asphalt mixtures are based on volumetric parameters and the compliance with certain mechanical and functional properties, and do not provide minimum requirements in terms of cracking ...
Evidence from progressive deterioration of the urban building stock is well known. This brings about a large social and economic impact due to maintenance costs and associated personal hazards. This thesis explores ways ...
Currently, there is a serious problem due to the large generation of municipal solid waste (MSW) due to the high consumption rates of the population and the short time of use of the products. Moreover, there is poor waste ...
(English) When analyzing structures for seismic design and performance assessment purposes, it has been common to assume that the ground motions or their equivalent representations correspond to that of the free-field ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
(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 ...
