[2+2+2] cycloaddition reactions involving allenes catalysed by rhodium
The development of new chemical processes for the formation of carbon-carbon bonds is an important topic in organic chemistry. In particular, the transition metal catalysed [2+2+2] cycloaddition reaction is a highly efficient ...
El riesgo y la responsabilidad objetiva
When we speak about strict liability we refer to the regime of liability that is free of any notion of fault. Therefore, in all those cases where the activity developed by the actor is subject to strict liability he will ...
Municipi, finances i elits locals en una ciutat catalana baixmedieval: Girona (1345-1445)

El estado de necesidad y el caso de la drogas en la doctrina del Tribunal Supremo. Una crítica desde la perspectiva latinoamericana
La evolución del paradigma prohibicionista ha incidido en múltiples ámbitos jurídicos. No se trata sólo de la producción legislativa en la que toma cuerpo, sino, además, de múltiples líneas jurisprudenciales que se han ...
Métodos estadísticos para evaluar la calidad del café
La presente tesis realizó el análisis y evaluación de los métodos estadísticos para valorar la calidad del café. En este sentido, se dio un aporte para tratar de cuantificar y cualificar la calidad del café mediante las ...
Climate change and the expansion of thermophilic fishes in the northwestern Mediterranean: the importance of studying condition and reproduction to understand the increase in their abundance
A direct consequence of sea warming in the Mediterranean is a increase in the abundance of thermo-tolerant species fish species such as Sphyraena viridensis, Pomadasys incisus, Pomatomus saltatrix and Trachinotus ovatus. ...
Nanotecnología en el sector papelero: mejoras en calidad y permanencia de las fibras de alto rendimiento y secundarias en una economía circular mediante el uso de nanofibras y el refino enzimático
Bio and nano technologies are absent or incipient in papermaking industry and, concretely, in recycling and high-yield pulps sectors. In this sense, the present Thesis uses cellulose nanofibers (CNF), both in bulk and on ...
El mestre/a d'Educació Musical en el nou marc de l'EEES: un estudi a partir de les competències professionals
This thesis studies the professional profile of Primary School music teachers, in the framework of the Catalan educational system and the construction of the Higher Education European Area (HEEA), focusing on the study of ...
Simultaneous localization and mapping using single cluster probability hypothesis density filters
The majority of research in feature-based SLAM builds on the legacy of foundational work using the EKF, a single-object estimation technique. Because feature-based SLAM is an inherently multi-object problem, this has led ...
Web-based application for medical imaging management
Prostate and breast cancer are the most common cause of cancers in men and women, respectively. Medical imaging plays an important role in breast and prostate cancer detection and evaluation. Then to prove that our web-based ...
Analysis and optimization of composite stringers
The use of the stiffened panels in the aircraft/aeronautical industry has been growing in the last decades. On the other hand, the exponential growth in the use of composite materials in the last years has had a ...
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 ...

The aim of this work is to understand the social representation sexual-affective diversity (DAS) for later use in educational settings. We used the following techniques: semi-structured individual interview (n = 8), free ...
Structure and reactivity of endohedral (metallo)fullerenes
It all started in 1985, when Kroto, Smalley and Curl discovered by serendipity a new carbon allotrope. They synthesized for the first time the C60 molecule, and named it as ”Buckminsterfullerene”, because of the similarity ...
