1. Assessing Energy Use and Carbon Emissions to Support Planning of Environmentally Sustainable Earthmoving Operations
Abstract : Road and infrastructure projects have significant environmental impacts due to their high energy consumption and CO2 emissions. Among it, earthmoving operations contribute disproportionately to these impacts because of their intensive use of heavy machinery. READ MORE

2. Studies of Nanowire Friction using AFM-based Manipulation
Abstract : In this thesis we present friction studies on InAs nanowires pushed laterally across surfaces by an AFM tip. The contact length in the direction of movement is of the order of a few tens of nanometers, and is thus comparable to that found in existing point-contact studies, but perpendicular to the motion the wire can be several microns in length.

3. Removal of Pharmaceuticals in Biofilm and Activated Sludge Systems
Abstract : Abstract The present work investigates i) the occurrence and removal of pharmaceuticals at Swedish WWTPs, and ii) potential causes for differences in the removal efficiency of pharmaceuticals at wastewater treatment plants. Particular attention is directed at the biological treatment and the pharmaceutical removal capacity per unit biomass of activated sludges and carrier biofilms of different origins. READ MORE

4. Aerotaxy - A Gas-Phase Nanowire Growth Technique
Abstract : In this thesis an efficient nanowire fabrication technique, called Aerotaxy, is investigated. Traditional nanowire fabrication techniques include the use of a substrate as a point of nanowire nucleation which limits the amount of nanowires that can be produced per unit time. READ MORE

5. Development of optimized radiation therapy using external electron and photon beams
Abstract : The development of new intensity modulated radiation therapy (IMRT) techniques and treatment optimization tools makes it desirable to further improve modulation methods by using scanned photon and electron beams. It is shown that the narrowest possible photon beams have the potential to improve the flexibility in dose delivery, speed up the dose delivery and improve the treatment outcome. READ MORE
