1. Artificial Ground Freezingin Clayey Soils : Laboratory and Field Studies of Deformations During Thawing at the Bothnia Line
Sammanfattning : Artificial ground freezing as a method to temporarily stabilize and create hydraulic sealing in urban as well as in rural areas has been used in a number of Swedish construction projects, particularly during the last decade. One problem with the freezing of soil and rock is that fine-grained clayey types of soils have showed a tendency to under certain circumstances, during the thawing process, create a pore water overpressure and to consolidate, despite a change in the external loading conditions.

2. Botniabanan - förväntningar i tid och rum på regional utveckling och resande
Sammanfattning : The aim of the thesis is twofold: to analyze the effects of the expectations on the Bothnia Line on the housing market and expectations on railway use. To fulfill these aims, three questions are considered:1. To what extent is property prices influenced by the expected effects of the Bothnia Line?2. LÄS MER
3. Mot framtiden på gamla spår? : Regionala intressegrupper och beslutsprocesser kring kustjärnvägarna i Norrland under 1900-talet
Sammanfattning : In this dissertation the construction of two coastal railways, the East Coast Line and the Bothnia Line, in the Norrland region of northern Sweden is used as a case study of how regionally based interest groups are formed, and how they gain access to decision-making processes on a national level. In periods when a number of preconditions were in place, a window of opportunity opened for the coastal railway that the regional elites could exploit. LÄS MER
4. Matching a changing world - the importance of habitat characteristics for farmland breeding Eurasian curlew
Sammanfattning : Where animals are and what they do, is the result of a continuous cost-benefit analysis of available alternatives. Choices have to be made, for example when settling in a breeding territory after migration, when foraging conditions change, when humans change the landscape, or when a predator approaches the nest.

5. Glaciodynamics, Deglacial Landforms and Isostatic Uplift during the last Deglaciation of Norrbotten, Sweden
Sammanfattning : The aim of this thesis was to reconstruct the glaciodynamics, deglacial landforms, isostatic uplift and to date the deglaciation. Glaciodynamics and deglacial landforms were focused on to provide a process and depositional model for De Geer moraine and Niemisel moraine and to reveal their internal and spatial relationship, based on detailed sedimentological and structural investigations.
