La tesis analiza las obras conservadas de las cinco primeras prosistas de las letras castellanas de las que tenemos constancia: Leonor López de Córdoba (1362-1430), Sor Constanza de Castilla (fallecida en 1478), Teresa de ...
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. ...
