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 ...
Mur Petit, Jordi (Data de defensa: 2006-01-11)
En aquesta tesi presentem un conjunt d'estudis sobre sistemes atòmics on els efectes quàntics són especialment destacats. Aquests estudis s'han dut a terme aplicant diverses tècniques de la física teòrica de molts ...
Blanch Mercader, Carles (Data de defensa: 2015-03-04)
The thesis belongs to the field of biophysicis, in particular we evaluate from a physicial perspective biological processes that occur at the celular and multicelular scales involving collective phenomena of self-organization. ...
Pérez Carrasco, Rubén (Data de defensa: 2013-02-04)
Cells are the minimum unit of life. They are born, they eat, the may grow, they may move, and, eventually, they die. By contrast, from a physicist point of view, cells are systems out of equilibrium continuously transducing ...
Illa i Tortós, Xavier (Data de defensa: 2007-01-23)
S:<br/><br/>L'objectiu principal d'aquesta tesi és aprofundir en l'estudi dels models microscòpics que permeten estudiar la histèresi. Aquest fenomen està present en moltes àrees de la física i ha despertat l'interès de ...
Rosa Agostinho, Nuno Filipe (Data de defensa: 2019-10-17)
For more than half a century, colliders have been in the forefront of studying the Standard Model (SM) predictions. The pinnacle of both SM and colliders occurred when on July the 4th 2012, at CERN Large Hadron Collider, ...
Gómez Orlandi, Javier (Data de defensa: 2015-09-09)
In this thesis we apply a multidisciplinary approach, based on statistical physics and complex systems, to the study of neuronal dynamics. We focus on understanding, using theoretical and computational tools, how collective ...
Pérez-Obiol Castañeda, Axel (Data de defensa: 2014-02-11)
In this thesis we have described the weak Lambda N to NN interaction, which is the main responsible for the decay of heavy hypernuclei, within the effective field theory (EFT) framework. The EFT is developed up to second ...
Parreño Garcia, Assumpta (Data de defensa: 1997-05-22)
In single A hypernuclei, a A hyperon can occupy any orbital in the hypernucleus since it is free from the Pauli exclusion principle due to its additional quantum number strangeness. <br/><br/>Due to the Pauli blocking ...
Guilleumas, Montserrat (Data de defensa: 1995-07-20)
Las transiciones de fase no siempre ocurren bajo condiciones de equilibrio. Un fluido puede ser conducido a un estado metastable. A pesar de ser internamente estable, existe otra configuración con un potencial termodinámico ...
Sáez Gómez, Diego (Data de defensa: 2011-03-31)
[spa] El proyecto de tesis está enfocado en el estudio de la evolución del Universo y más concretamente en la explicación del mecanismo que produce su actual expansión acelerada, y que probablemente sea el mismo que ha ...
González Fraile, Juan (Data de defensa: 2014-09-05)
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 ...
Casanellas Vilageliu, Laura (Data de defensa: 2013-03-22)
Wormlike micelles are viscoelastic fluids that present an intermediate behavior between solids and ordinary liquids since they are elastic at short time scales but flow easily at large time scales. In opposition to Newtonian ...
Cerutti, Francesco (Data de defensa: 2013-07-16)
The main problematics related to the determination of a set of Parton Distribution Functions (PDFs) are presented and, after a brief discussion on different strategies adopted by other groups to address them, the NNPDF ...
Formosa Jordan, Pau (Data de defensa: 2013-04-29)
Multicellular organisms are constituted by different kinds of cells which are arranged in a particular way, forming tissues with specific functions. The organization of these different cells can give rise to regular ...
Ciudad Álvarez, Aleix (Data de defensa: 2008-05-15)
[eng] The discovery of molecular motors was not a single and isolated event but a set of gradual approaches from microscopic to nanoscopic systems. For example, the knowledge of the activity of muscle cells is pretty old, ...
Acín dal Maschio, Antonio (Data de defensa: 2001-06-01)
[spa] En esta Tesis se ha realizado en el marco de la Información Cuántica, una nueva disciplina de la Física Teórica en la que se funden la Mecánica Cuántica con la Teoría de la Información. El estudio se ha centrado en ...
Rodríguez Lázaro, Guillermo (Data de defensa: 2014-06-30)
The mechanics and elasticity of red blood cells (RBCs) determine the capability to deform of these cells when passing through the thinnest capillaries, where the delivery of oxygen takes place. The understanding of the ...
Soriano i Fradera, Jordi (Data de defensa: 2003-02-28)
Se presenta un trabajo experimental sobre el crecimiento de interficies rugosas en medios desordenados. El experimento consiste en una celda de Hele-Shaw en cuya placa inferior se han distribuido una serie de obstáculos ...
Planells Noguera, Xumeu (Data de defensa: 2014-11-06)
In this thesis we study the possibility that QCD breaks parity at high temperatures and densities, a scenario that may be tested in heavy ion collisions. We present two different approaches to this problem. On the one hand, ...
