Development of new reusable materials based on Ru complexes with catalytic activity for olefin epoxidation and nitrile hydration
In this thesis we present the synthesis and characterization of different types of ruthenium complexes containing N-donor ligands together with dmso, Cl and H2O ligands, along with their complete characterization through ...
Green citites and green urban economy; contributions from case studies for a necessary low-carbon future
City Governments engaged in climate change mitigation and adaptation face the multiple challenge of self-commitment, the need to involve their communities and stakeholders, and top-down and multi-scalar processes out of ...
Socioeconomic status determines floristic patterns in suburban domestic gardens: implications for water use and alien plant dispersal in the Mediterranean context
The recent growth of low-density urban developments in the Mediterranean coast has led to an increase in the number of private domestic gardens. This thesis examines the flora, features and management practices of 258 ...
Intermittency of turbulence in natural waters: patchiness in the thermocline of a lake under low winds and small-scale intermittency in the bottom boundary layer of a tidal flow
Turbulence intermittency influences so many processes in natural waters on a wide range of scales. This work analyzes intermittency, both internal and external, by considering two cases: the thermocline of a small lake ...
Technologies to determine quality parameters and the effect of high pressure processing on dry-cured ham
The research for new technologies able to determine quality parameters as well as study the effect of High Pressure Processing (HPP) on dry-cured ham is of scientific interest because the information obtained is useful for ...
Los sistemas de información en el sector hotelero: un modelo de éxito
This thesis includes a review of how the information technology is used at present in the hotels, as well as the functionality expected from the hotels information systems. We compare these systems characteristics with ...

Analysis of cooperation and electron delocalization in intermolecular hydrogen bonds
This thesis presents different studies on hydrogen bonds that occur between two molecules. It is because of the biological importance of DNA that the base pairs, and other compounds with similar hydrogen bonds as these ...
Bioremediation of nitrate-polluted groundwater using bioelectrochemical systems
The presence of nitrates (NO3-) in groundwater is a worldwide concern. The high energy demand and environmental impact of available technologies requires investigating new technologies. This thesis was focused on investigating ...
Perceptual information-theoretic measures for viewpoint selection and object recognition
Viewpoint selection has been an emerging area in computer graphics for some years, and it is now getting maturity with applications in fields such as scene navigation, volume visualization, object recognition, mesh ...
Linking river sediment physical properties to biofilm biomass and activity
River sediments are composed by a variety of grain sizes which determine their permeability and biogeochemistry. The aim of this thesis was to test whether differences in river sediment physical characteristics generate ...
