1. Anaerobic digestion of crop residues at low temperatures
Sammanfattning : Biogas is a renewable source of energy. Residues from agriculture contain considerable energy potential and are suitable substrates for biogas production, but in Sweden the utilization of these residues is low. The economic feasibility of biogas production in general is low, and only limited subsidies are provided by the state. LÄS MER

3. Design and Construction of Low-Temperature Scanning Tunnelling Microscope for Spectroscopy
Sammanfattning : This thesis discusses some of the fundamental requirements needed to be fulfilled when constructing a low temperature scanning tunnelling microscope (STM). Three different designs, two non-vacuum and one ultra-high vacuum (UHV), based on either inertial-mass or novel stepper motor principles are presented. LÄS MER
4. Thermo-Mechanical Behaviour of Refrigerated Caverns in Hard Rock
Sammanfattning : For almost 4 decades, underground caverns in hard rock have been used to store liquefied petroleum gases (LPG) and refrigerated products, such as foods and chemicals. The design of such facilities has, however, been founded on relatively limited knowledge of the reaction of rock masses to cooling. LÄS MER
