21. Ultrasonic characterization of materials and multiphase flows
Sammanfattning : This thesis deals with three different applications of ultrasound measurement technology. In process industries like the mining industry, the oil and gas industry, and the paper pulp industry, multiphase flows play an important role. LÄS MER
22. Sulphide-rich tailings remediated by soil cover : evaluation of cover efficiency and tailings geochemistry, Kristineberg, northern Sweden
Sammanfattning : The efficiency of soil cover as a method of remediation of sulphide-rich tailings has been studied at an impoundment at the Kristineberg mine, Northern Sweden. Two variations of soil cover were used in the remediation. The major part of the impoundment was covered with a 1.0 m layer of till where the groundwater table was shallow. LÄS MER
23. Steel fibre reinforced concrete toppings exposed to shrinkage and temperature deformations
Sammanfattning : The work presented in the thesis primarily focuses on problems that are characteristic for thin layers of concrete exposed to imposed loads. More specific, the work aims at investigating, or rather finding ways to evaluate the efficiency of steel fibres as regards the limitation of crack widths in concrete under restrained conditions.

24. Decision making in emergency management
Sammanfattning : The thesis is based on two studies conducted on behalf of the Swedish Emergency Services Agency. One study focused on the problems associated with selection and training of future emergency directors in Sweden. The other study surveyed the emergency directors’ needs for decision support systems in major accidents. LÄS MER
25. Methods for collecting and analysing simultaneous strain and moisture data during wood drying
Sammanfattning : Improved understanding of moisture and mechanical behaviour is an international objective for wood drying research. The main objective of this licentiate thesis work was to develop an experimental method suitable for collecting valuable response data related to the moisture and mechanical behaviour of drying wood.
