16. Long-term sickness absence : aspects of society, work, and family
Abstract : Sickness absence has varied considerably in Sweden over time and increased substantially between 1997 and 2002, especially among women. The composition of such absence has also changed in that there have been increases in sick leave due to mental illness, prolongation of sickness absence periods, and a larger proportion of women than men on long-term sick leave.

17. Topics in Dynamic Spectrum Access : Market Based Spectrum Sharing and Secondary User Access in Radar Bands
Abstract : The steady growth in demand for spectrum has increased research interest in dynamic spectrum access schemes. This thesis studies some challenges in dynamic spectrum access based on two strategies: open sharing and hierarchical access. READ MORE

18. Adiabatic Andreev Levels Under Irradiation - Coherent Dynamics and Dephasing
Abstract : A study of the Andreev level current through a weakly voltage-biased single-mode superconducting quantum point contact under microwave irradiation is presented. The applied microwave field induces resonant transitions between the current carrying Andreev states localized to the contact region, which results in an increase of the dc subgap current by several orders of magnitude.

19. Hadronic Decays of the ω Meson
Abstract : Two decay channels of the ω(782) meson, into π+π-π0 and π+π-, are studied. The dynamics of the three-pion channel is represented using a two-dimensional distribution, called a Dalitz plot. A high-statistics Dalitz plot distribution is needed to test theoretical predictions and increase understanding of the decay mechanism. READ MORE

20. Majorana Representation in Quantum Optics : SU(2) Interferometry and Uncertainty Relations
Abstract : The algebra of SU(2) is ubiquitous in physics, applicable both to the atomic spin states and the polarisation states of light. The method developed by Majorana and Schwinger to represent pure, symmetric spin-states of arbitrary value as a product of spin-1/2 states is a powerful tool that allows for a great conceptual and practical simplification.
