16. Repatriation, Integration or Resettlement : The Dilemmas of Migration among Eritrean Refugees in Eastern Sudan
Sammanfattning : The refugee problem continues to be a major international concern. This study is based on the situation of Eritrean refugees in Kassala town, Sudan, but provides some general insights in the on-going debate about the notions of home, transnationalism, citizenship, integration and return migration.

17. Tectonic History and Present-Day Deformation in the Zagros Fold-Thrust Belt
Sammanfattning : This thesis uses various approaches such as observation of satellite images, field investigations, analogue modeling and GPS measurements to constrain deformation of the basement and sedimentary cover of the Zagros fold-thrust belt in time and space.Focal mechanism solutions of most earthquakes indicate that deformation in the Zagros basement is due to shortening and thickening through numerous thrust faults.

18. Boundary-layer structure in flow over a heterogeneous surface
Sammanfattning : Airborne measurements performed within the framework of NOPEX (Northern Hemisphere Land Surface Climate Processes Experiment) have been used to study processes related to fluxes of momentum, heat, and moisture in the boundary layer in the Swedish boreal region. The NOPEX area is characterized as heterogeneous with respect to vegetation. LÄS MER
19. Environmental Assessments of Landscape Changes : Interdisciplinary studies in rural Tanzania
Sammanfattning : This thesis aims to show how biogeophysical and social processes are interlinked in landscape change, and to propose approaches for interdisciplinary environmental assessments (such as EIAs), concentrating on developing countries’ situations, and representation of findings from such studies. Landscape in its holistic sense is a very good concept and basis for intellectual and practical use in environmental dialogues. LÄS MER
20. Improved data analysis methods for the millimetre-wave observation of strato-mesospheric ozone and winds over Northern Sweden
Sammanfattning : This thesis analyses and discusses the work done to improve an ozone retrieval method. The newly implemented method aims to invert emission spectra measured with the millimetre-wave radiometers KIMRA and MIRA2 at the Swedish Institute of Space Physics (IRF) in Kiruna. LÄS MER
