21. Heterogeneity-Induced Channelling, Flow-Wetted Surface, and Modelling of Transport in Fractured Rock
Sammanfattning : Heterogeneities in fractured rock are found at all scales; from the scale of individual fractures, to the scale of fracture networks, and to the largest regional scales. These heterogeneities cause challenges for modelling and parameter estimation of flow and solute transport. LÄS MER
22. An integrated approach to study pharmaceuticals and their microbial transformation products: formation and environmental behavior in water/sediment systems
Sammanfattning : Pharmaceuticals are emerging organic micropollutants that are frequently detected in the aquatic environment. While information on their environmental occurrence is substantial, knowledge gaps exist with respect to their environmental transformation. LÄS MER
23. Damage and thermally induced defects in railway materials
Sammanfattning : A major concern for the railway industry today is the problem of rolling contact fatigue (RCF) damage in wheels and rails as a result of increased traffic, accelerations, and loading conditions. The wheel/rail contact condition that occurs in railway applications is complex, and it is essential to understand the associated damage from combined mechanical and thermal loadings in order to predict component life and develop appropriate maintenance systems.

24. Soil Erosion and Mass Movement in Agricultural Drainage Ditches
Sammanfattning : Agricultural drainage ditches degrade over time. This degradation is often due to soil erosion, which can cause mass movement (bank failure) when the toe of the bank is eroded or the slope of the bank is too steep. Soil eroded or displaced by mass movement is either transported by the flowing water or deposited in the drainage ditch. LÄS MER
25. Micro-scale studies of wear
Sammanfattning : The development of materials for tribological components is constantly striving to more sophisticated properties, specialised for specific applications. This progress requires and depends to a large extent on a parallel development of the theoretical knowledge of wear and on development of the experimental tools for investigating wear in the research lab as well as in the field.
