In our opinion, it is fair to distinguish two separate branches in the origins of model theory. The first one, the model theory of first-order logic, can be traced back to the pioneering work of L. ...
Centelles Aixalà, Mario (Date of defense: 1992-07-30)
The nuclear many-body problem is nowadays being increasingly approached on the basis of a relativistic formalism. Microscopic Dirac-Brueckner-Hartree-Fock (DBHF) calculations starting from a realistic ...

Aquest treball no pretén ser un estudi exhaustiu sobre la flora bentònica marina de Namíbia, sinó simplement una base per portar-lo a terme en un futur. El que sí pretén, en canvi, és oferir una ...
Serrano Moral, Ma. Ángeles (María Ángeles) (Date of defense: 1999-05-28)
La tesis presenta una cuidadosa descripción del comportamiento dinámico de las antenas esféricas resonantes de ondas gravitatorias cuando son excitadas por radiación gravitatoria, o también por señales ...

Our main goal is to study certain aspects of the dynamics of fluids with magnetic particles in suspension, based on their promising practical applications as new materials as welI as on its fundamental ...
Reigada Sanz, Ramon (Date of defense: 1997-11-27)
Los sistemas de reacción-difusión donde el proceso difusivo es la etapa lenta están controlados, a bajas dimensionalidades, por las fluctuaciones en las distribuciones iniciales de reactivos. Concretamente, ...
Manrique Oliva, Alberto (Date of defense: 1995-09-26)
En la tesis se presenta un método semianalítico para describir el crecimiento de objetos virializados en el escenario de inestabilidad gravitatoria. Se ha desarrollado el formalismo del sistema confluente ...
