1. Early structural and metamorphic evolution of the Scandinavian Caledonides: a study of the eclogite-bearing Seve Nappe Complex at the Arctic Circle, Sweden
Sammanfattning : In the Seve Nappe Complex of the Swedish Caledonides, coronitic diabases pass into eclogites; sometimes the transition occurs within one and the same boudin. Calculated pressure-temperature conditions for the eclogite facies stage are 20-27 kbar and 650-750°. LÄS MER
Sammanfattning : The urban transformation that is taking place in Kiruna, a Swedish town well above the Arctic Circle in the sub-arctic climate, is due to the ground deformation caused by iron ore mining and it is affecting all the infrastructures of the town. This thesis focuses on the studies about the district heating for the town of Kiruna. LÄS MER
Sammanfattning : There is currently an ongoing urban transformation in a small Swedish town named Kiruna, it is located in the very north of Sweden well above the Arctic Circle in a sub-arctic climate. Large part of the town will be relocated due to the ground deformation that is caused by the progressing iron ore mining activity and it is affecting all infrastructures of the town. LÄS MER
Sammanfattning : This thesis is about competitive strength in the global markets for iron ore. Its focus is on the Swedish iron ore producer, LKAB, and its role in this global market. The finding of new vast deposits of iron ore in Brazil and Australia, together with falling transportation costs, meant that LKAB started to meet fierce competition in the 1970s. LÄS MER
5. Condition monitoring of railway vehicles : a study on wheel condition for heavy haul rolling stock
Sammanfattning : A railway is an energy efficient mode of transport as it uses the low resistance contact between wheel and rail. This contact is not frictionless and causes wear on both surfaces. The wheel-rail guidance is made possible by the shapes of wheel and rail profiles. LÄS MER
