11. Simulation of rutting phenomenon in road surfaces : by the use of FEM and viscoelasticity
Sammanfattning : .... LÄS MER
12. GIS-based decision support systems to minimise soil impacts in logging operations
Sammanfattning : Mechanised logging operations can leave negative impacts, like ruts, on forest soils. To avoid this, forestry planners and machine operators need decision support systems that can estimate soil trafficability and help to minimise soil impacts. LÄS MER
13. On forestry machine and soil interaction for sustainable forestry
Sammanfattning : More than 50 percent of the land area of the Nordic countries Finland, Norway, and Sweden are covered by dense forests and they are among the most important producers of forest products in the world. Forestry in these countries is based on sustainable management principles – reforestation follows harvesting. LÄS MER
14. Evaluation of Asphalt Field Cores with Simple Performance Tester and X-ray Computed Tomography
Sammanfattning : The importance of aggregate structure and air voids distribution for asphalt mixture rutting and cracking performance has been well established on the basis of experience and is well documented in the literature. Past and current investigations are limited to assessment of performance based on macroscopic behavior due to the difficulty associated with the quantitative measurement and analysis of the internal structure of asphalt mixtures.

15. Seasonal variations in general activity, behaviour and cutaneous glandular structures in reindeer (Rangifer tarandus L.)
Sammanfattning : The locomotor activity of the reindeer is separated into a diurnal and a nocturnal phase which, in turn, consists of a number of short-term activity bursts. The onset and termination of diurnal and nocturnal activity are largely in synchrony with sunrise and sunset. LÄS MER
