31. Analysis and modelling of plastic bending processes
Sammanfattning : It is well known that anisotropic properties of material allect forming of sheet metals and that non-homogeneous deformation across thickness of a bend gives rise to residual stresses. The interaction between material and process parameters determines, in a very complex manner, the formability of material. LÄS MER
32. Effects of silvicultural treatments in young Scots pine-dominated stands on the potential for early biofuel harvests
Sammanfattning : The overall objective of the work underlying this thesis was to increase knowledge regarding growth of young Scots pine (Pinus sylvestris L.) - dominated mixed forests in northern Sweden and the potential for combining early biofuel harvest in such stands while leaving crop trees for future harvests. For this purpose, several studies were made. LÄS MER
33. 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
34. Reproductive strategies and liming responses in forest field-layer flora
Sammanfattning : Liming increased species richness, in accordance with the species pool hypothesis, and number of plants of individual species in beech forest field-layer vegetation, by increasing establishment by seedlings and vegetative offspring. Turnover rates also increased, suggesting the explanatory value of the carousel model. LÄS MER
35. Spiral Grain in Norway Spruce
Sammanfattning : Wood is a major construction material that is used in many contexts, and for different purposes. Serious problems may arise, however, when moisture related deformations as twist occur in wood used in different types of building structures, joinery and furniture. LÄS MER
