Computational mechanistic studies of C-H and C-X activated organometallic species with first-row transition metals
During the last decades, computational chemistry has become a resourceful tool in the quest to understand and predict the mechanism and the reactivity of chemical systems. This is especially true in the area of ...
Flow alteration and wastewater inputs effects on freshwater communities in Mediterranean rivers
Mediterranean rivers are characterized by high hydrological variability and heterogeneity of habitats, placing themselves amongst arid and temperate climates, and are associated with high biological diversity. On the ...
Multiple stressor effects on river biofilm communities: from community composition to ecosystem processes using experimental mesocosms
Human exploitation of river ecosystems, together with the increasing pressure that represents climate change, is posing rivers worldwide at risk. In rivers, microorganisms are ecologically very important. Most of ...
Development of new transition metal complexes for their use in sustainable catalytic processes and as antitumoral agents
In this thesis we present the synthesis and characterization of different types of ruthenium complexes containing N-donor ligands together with monodentate ligands, along with their complete characterization through s ...
First row transition metal carbenes: from supporting ligands to organic reactive fragments
In the last decades, carbenes have shown a huge potential and versatility in organometallic and organic chemistry. In each of these fields, first row transition metal chemistry is less developed than noble metal complexes. ...
KSL-W analogues, peptide conjugates and tryptophan-containing cyclic peptides with activity against plant pathogens
Plant diseases produced by bacteria are responsible for considerable economic losses. These phytopathologies are highly contagious and difficult to control. With this aim, we selected peptides reported as plant defense ...
A mechano-perfusion bioreactor for tissue engineering
Tissue Engineering plays a vital role in tissue construct to repair, maintain or replace tissues. Those tissues can be cultivated in vivo or in vitro using devices such as bioreactors. There are several approaches to ...
Study and conceptualization of Vusiness: a model for the creation and management of companies based on values
The global economy has suffered a serious crisis and rapid slowdown. globalization significantly increases the unbalanced use of finite, non- 2/1 renewable sources of energy, aggravating climate change. Millions of ...
Cyclization reactions for the functionalization of fullerenes: experimental and theoretical studies
Fullerenes are a group of spherical molecules with outstanding 2/1 physicochemical properties that make them important materials in a variety of fields, ranging from biomedicine to photovoltaics. However, in order ...
Online 3D view planning for autonomous underwater exploration
Autonomous underwater vehicles are used nowadays in many applications. One of the applications is mapping of a particular area of the ocean. Quen the robot needs to cover the area of interest and no prior knowledge of ...
Medical imaging applied to teaching and meat science
Medical imaging has greatly progressed to become an essential technology in current clinical processes. However, advances in diagnostic imaging have not been applied to the same extent to other fields such as education and ...
La imatge dels museus a través de l'arquitectura. Anàlisi de l'arquitectura exterior dels museus registrats de la província de Girona
In the 19th century, the museum archetype was based on an architecture of classical lines and a palace image. The current trend of new museums buildings is characterized by its typological vagueness and the lack of an ...
Factores psicosociales de riesgo y protección de la salud y bienestar entre los profesionales del transporte sanitario
Several studies highlight the fact that ambulance personnel are exposed to multiple psychosocial risk factors that can lead, among others, to burnout syndrome. There are few studies that provide information on protective ...
Advanced thermal analysis of ReBCO superconductor precursor films and functional oxides
High temperature superconductivity and in particular YBa2Cu3O7-x (YBCO) coated conductors (CCs) are a crucial technology for the drastic reduction of CO2 emissions. Since nowadays YBCO CCs are not competitive economically, ...
Estudi de la funció del factor de transcripció StNAC103 en el fel·lema
The results obtained in this thesis indicate that StNAC103 promoter activity is induced in tissues undergoing suberin synthesis. Moreover StNAC103 transcript accumulation is concomitant to that of CYP86A33 and takes place ...
Novel developments in the Diffusive Gradient in Thin films (DGT) technique for the determination of bioavailable mercury and other trace metals in aquatic and terrestrial environments
This thesis is focused on the use of the Diffusive Gradient in thin film (DGT) technique for the analysis of bioavailable mercury and other trace metals in water and soil. Homemade DGT devices using a selective ion-exchange ...
Dietary patterns in the etiology of lymphoid neoplasms
Diet is a key modifiable risk factor for several neoplasms, but evidence for lymphoid malignancies is still inconsistent. Previous epidemiological studies were mostly focused on single dietary components (i.e. nutrients ...
Occurrence and behaviour of silver nanoparticles in the environment: analytical methodologies and laboratory studies
The production of engineered nanomaterials (ENMs) has grown in last years due to their special physicochemical properties in respect to their bulk counterparts, derived from their small size (1-100 nm). Among the existing ...
Abatement of siloxanes in sewage biogas: coupling adsorption and biological treatments
The anaerobic digestion of organic matter causes the formation of biogas that can be used in energy conversion systems for the production of electricity and heat, injection into the gas grid or as a fuel. However, biogas ...
Evaluation and comparison of advanced treatment technologies to enhance the removal of pharmaceutical active compounds from wwtp secondary effluent
The presence of several pharmaceutical active compounds (PhACs) in water bodies has garnered increasing attention and worldwide concern. The effluents from wastewater treatment plants (WWTPs) are one of the main sources ...
