1. Inflammation-associated genes and genetic variations in colorectal cancer
Sammanfattning : Colorectal cancer is a major cause of morbidity and mortality around the world, each year affecting about one million individuals worldwide. The disease is characterized by an accumulation of genetic alterations, and a sequence of events leading to the development of an invasive and metastasising tumour. LÄS MER
2. Studies of the radiative properties of some diatomic molecules
Sammanfattning : .... LÄS MER
3. A Theoretical Study of Atomic Trimers in the Critical Stability Region
Sammanfattning : When studying the structure formation and fragmentation of complex atomic and nuclear systems it is preferable to start with simple systems where all details can be explored. Some of the knowledge gained from studies of atomic dimers can be generalised to more complex systems. LÄS MER
4. Ways of determining and characterising resonances in scattering processes
Sammanfattning : Scattering cross sections very often display structures. To clarify if these structures correspond to resonances one has to check if they are poles of the scattering matrix (S-matrix) in the fourth quadrant of the complex momentum plane. Furthermore, the states corresponding to these poles also need to have an appropriate scattering amplitude. LÄS MER
5. Solving the quantum scattering problem for systems of two and three charged particles
Sammanfattning : A rigorous formalism for solving the Coulomb scattering problem is presented in this thesis. The approach is based on splitting the interaction potential into a finite-range part and a long-range tail part. In this representation the scattering problem can be reformulated to one which is suitable for applying exterior complex scaling. LÄS MER
