1. Property fragmentation : Redistribution of land and housing during the Romanian democratisation process
Sammanfattning : In the context of democratisation in the early 1990s, the governments in Central and East Europe (CEE) had to decide how to deal with property that had been confiscated under state socialism. Nationalised housing and collectivised land were to a varying extent returned to former owners and their heirs by means of restitution, as well as being distributed to other citizens who were in possession of the users’ rights to such properties.

Sammanfattning : In this work we will discuss fragmentation and molecular growth processes in collisions of Polycyclic Aromatic Hydrocarbon (PAH) molecules, fullerenes, or their clusters with atoms or atomic ions. Simple collision models as well as molecular structure calculations are used to aid the interpretations of the present and other experimental results. LÄS MER
Sammanfattning : This thesis deals with fragmentation of complex molecular ions, especially biomolecules, in gas phase collision experiments. The aim is to investigate the relations between energy deposition and fragmentation and to shed light on the mechanisms behind energy and charge transfer processes in collisions involving the building blocks of life.

Sammanfattning : This thesis presents experimental data on the fragmentationof gas phase sulfur hexafluoride (SF6) and deutheromethane(CD4) molecules after their interaction with synchrotronradiation in the energy range of 70-200 eV. The data wasobtained using coincidence spectroscopy between energy resolvedelectrons and ions (EREICO). LÄS MER
Sammanfattning : This thesis is based on the work that was done during 1992--1996 at the DELPHI detector at LEP. Its main parts are outlined below. The brief Introduction gives an overview of the science of Particle Physics, its development and contemporary status. LÄS MER
