In this thesis, we present a proof of the meromorphic non-integrability for some problems arising from Celestial Mechanics, as well as a new necessary condition for partial integrability in a wider Hamiltonian setting. ...
In this thesis we present several studies on the origin of masses at the LHC. First we study the indirect effects of new physics on the couplings of the recently discovered Higgs boson and on the electroweak symmetry ...
In this tesis we study numerical propieties of surfaces and threefolds, mainly fibred over curves, the so called "slope" of the fibration. We prove partially a conjecture of Fujita on the semiampleness of the direct image ...
Comparative studies between different enzyme labelled fluorescence (ELF) protocols and fluorescence quantification methods were performed to improve the quantification of single-cell phosphatase activity (PA) measurements ...
Three-dimensional ligand-based virtual screening methods have been used for many years in drug discovery, with a variable success depending on different factors, such as the complexity of the target system or the suitability ...
This is a thesis about word definition. Early developmental studies of word definition, tested nous rather than other morphological categories (adjectives, verbs). As some authors have pointed out (McKeown, 1991) a proper ...
Multi Agent Systems (MAS) are computerised systems composed of autonomous software agents that interact to solve complex problems. Within a MAS, agents require some mechanism to coordinate their activities. In the MAS ...
[eng] Deciphering the mechanisms of human declarative memory is one of the main goals of neuroscience. Theoretical models such as Standard Consolidation Theory (Alvarez and Squire, 1994) and the Multiple Trace Theory (Nadel ...
[ENG] Venous malformations (VM), the most frequent type of vascular malformations, are localized developmental defects occurring during vascular morphogenesis that generat dilated, tortuous venous channels surrounded by ...
Oncolytic virus (OV)-based therapies have an emerging role in the treatment of solid tumors, involving both direct cell lysis and immunogenic cell death. Nonetheless, tumor- associated stroma limits the efficacy of oncolytic ...
La toponímia s’estudià primer a Alemanya i França (1863 - principis del segle XX). Més endavant s’hi dedicaren publicacions periòdiques: Zeitschrift für Ortsnamenforschungen (Munic, 1925), Revue de dialectologie et toponymie ...
En citar L’Onomàstica del Terme Municipal de Calafell ens referim a la recerca, l’estudi i la recopilació dels noms propis que existien en aquest municipi i en el seu terme pels voltants de l’any 1950, i en llurs evolucions ...
[cat] Atenent als fets de que la classificació europea s’ha desenvolupat, principalment, dins les fronteres de cadascun dels països portant a notables diferències dels corresponents tipus de vegetació -fins i tot entre ...
This work is the result of extensive research on sexual and ontogenetic variation of parameters with mechanical significance in a radius bone in two species of odontocetes: Stenella coeruleoalba (Sc) and Pontoporia Blainvillei ...
Este estudio analiza el desarrollo postnatal del femur y la tibia de una muestra de individuos vivos de principios del siglo XXI de Barcelona. El material utilizado han sido 1140 telemetrias (radiografías de la extremidad ...
The aim of this thesis is to develop standard and practical approaches for the semantic integration of biological data and services. The thesis considers various scenarios where ontologies may benefit bioinformatics web ...
Southern Pyrenees has provided an abundant fossil record of dinosaur eggs and eggshells. Historically, the oofamily Megaloolithidae has shown its predominance over any other group of fossil eggs in this region. In addition, ...
Opa1 is a mitochondrial dynamics protein responsible for the fusion of the inner mitochondrial membrane, the maintenance of cristae morphology, and involved in mitochondrial DNA stability. In this study we have explored ...
1. (R)-Phenylglycinol-derived oxazolopiperidone lactams can be converted to enantiopure open-chain amino ester scaffolds by alkaline hydrolysis of the N-Boc 2-piperidones resulting from the reductive cleavage of the ...
The conventional Biological Nitrogen Removal (BNR) process consists on the oxidation of ammonia to nitrate (nitrification) and the subsequent reduction of nitrate to nitrogen gas (denitrification) using biodegradable COD ...
