1. In the Shadows of Poland and Russia : The Grand Duchy of Lithuania and Sweden in the European Crisis of the mid-17th century
Sammanfattning : This book examines and analyses the Union between the Grand Duchy of Lithuania and Sweden signed in 1655 at Kėdainiai and the political crisis that followed. The union was a result of strong separatist dreams among the Lithuanian-Ruthenian Protestant elite led by the Radziwiłł family, and if implemented it would radically change the balance of power in the Baltic Sea region.

2. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation
Sammanfattning : Low temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. LÄS MER
3. Impact of moisture on long term performance of insulating products based on stone wool
Sammanfattning : Demands for energy have been increasing in the whole world. According to higher consumption, the price of energy rises yearly too. This evokes usage of insulating products in a wider range. LÄS MER
4. The zoo-geomorphological impact of fossorial rodents in sub-polar alpine environments
Sammanfattning : The geomorphological impact of small fossorial mammals (adapted to digging and living underground), such as rodents can be significant, and both their direct and indirect effects may contribute to landscape formation. This thesis is based on empirical field studies of two burrowing rodent species in sub-polar environments, namely invasive House mice (Mus musculus) on sub-Antarctic Marion Island and Norwegian lemmings (Lemmus lemmus) in sub-Arctic Abisko.

5. Durability of sprayed concrete : steel fibre corrosion in cracks
Sammanfattning : A combination of sprayed concrete technique and steel fibre technology gives obvious advantages when saving the work needed to place conventional reinforcement. In rock strengthening applications this is most accentuated. Sprayed concrete in general, made by skilled workmen, will generally be of high quality and good durability. LÄS MER
