Mingorance Jiménez de la Espada, Ana (Date of defense: 2006-01-16)
The adult central nervous system (CNS) has a very little capability to regrow its connections after lesion. The lack of axonal regeneration is a multifactorial problem, which is mainly due to the presence of inhibitory ...
Villuendas Pellicero, Diego (Date of defense: 2016-02-03)
The goal of this work is to investigate the magnetic deflagration phenomena in two very different magnetic systems, using two very different experimental techniques. In the first chapter of this dissertation I introduce ...
Statuto, Nahuel (Date of defense: 2019-07-22)
The goal of this thesis is to explore and control the magnetization dynamics on magnetic multilayered thin films through two different techniques: the application of strain and spin- polarized currents, which represent ...
Oltra González, Javier (Date of defense: 2022-10-28)
[eng] INTRODUCTION: This doctoral thesis is centered on Parkinson’s disease (PD) with rapid eye movement sleep behavior disorder (RBD) as a clinical subtype. Characterizing subtypes is one of the main ongoing objectives ...
González Alonso, David (Date of defense: 2014-04-25)
Bé sigui el canvi de temperatura que experimenta un material a l’aplicar-li un camp magnètic en condicions adiabàtiques, o bé sigui el canvi d’entropia del material com a conseqüència de la modificació del camp magnètic en ...
Escoda Pastor, Carmen (Date of defense: 2007-04-01)
El emplazamiento es y siempre ha sido un condicionante de la obra arquitectónica, pero ha sido a partir de la arquitectura del Movimiento Moderno que se le ha otorgado un papel protagonista en ese juego de relaciones que ...
Lendínez Escudero, Sergi (Date of defense: 2016-01-20)
Research in magnetic materials leads to new devices and technologies. As the technology progresses, the devices become smaller and this miniaturization allows more storage capacity and lower costs in the production of new ...
Frau Méndez, Pau (Date of defense: 2012-06-12)
It is some observational evidence that dense cores are the birthplace of low-mass stars. These regions, apparently quiescent, are capable of surviving several free-fall times and, potentially, collapse and form stars. ...
Casanova i Fernàndez, Fèlix (Date of defense: 2004-03-09)
This Ph.D. Thesis has been devoted to the preparation and characterisation of bulk Gd5(SixGe1-x)4 alloys and to the study of the magnetocaloric effect at the first-order magnetostructural transition appearing in these ...
Garcés Crespo, Miguel (Date of defense: 1995-05-04)
La integración de la magnetoestratigrafía y la bioestratigrafía en las sucesiones vallesienses del Vallès Occidental (Cuenca del Vallès-Penedès) ha aportado un marco cronológico de alta resolución para una porción del ...
Barberà i Bota, Xavier (Date of defense: 1999-11-08)
La tesis presentada se centra fundamentalmente en el establecimiento de la magneto-estratigrafía y magnetobiocronología de las sucesiones oligocénicas del sector oriental de la cuenca del Ebro. Los resultados derivados del ...
Ogaya Garcia, Xènia (Date of defense: 2014-09-30)
The electromagnetic methods are especially interesting for the characterisation and monitoring of geological storage of CO2 sites. The electrical resistivity is a physical parameter that depends on the mineralogical ...
Martí i Castells, Anna (Date of defense: 2006-07-04)
The magnetotelluric (MT) method is a geophysical method that allows characterizing the electric properties of the Earth materials. Within the frame of this method, this thesis is divided in two parts.<br/>The first part ...
Prado Villegas, Patricia (Date of defense: 2007-02-23)
La revaluació a gran escala espacial (> de 300 Km) i mitjançant mètodes de quantificació directa, del impacte de l'herbivorisme en els ecosistemes de <i>Posidonia oceanica</i> va revelar pèrdues de biomassa foliar molt ...
Coll Benejam, Catalina (Date of defense: 2022-10-26)
[eng] Transmission Electron Microscopy (TEM), since its first implementation by Ernst August Friedrich Ruska and Max Knoll in 1931, has been an essential technique in the nanoscience and nanotechnology field. In the ...
Font i Puig, Carme (Date of defense: 2012-09-14)
La enfermedad tromboembólica (ETV) venosa representa hoy la segunda causa de muerte y un factor de gran morbilidad en el paciente oncológico. Hay gran interés en conseguir marcadores clínicos y biológicos que permitan ...
Roca i Saumell, Carme (Date of defense: 2003-12-02)
Durante los últimos treinta años, diversos colectivos de población africana se han establecido en Catalunya, y el Maresme ha sido una de las comarcas donde la inmigración ha sido cuantitativamente remarcable.<br/><br/>En ...
Varo Cobos, Rosauro (Date of defense: 2020-10-02)
[spa] Las tasas de mortalidad y morbilidad asociadas a la infección por P. falciparum siguen siendo, a pesar de la disponibilidad de tratamiento antimaláricos efectivos, excepcionalmente elevadas. De hecho, tras recibir ...
