1. Wetting and levelling of toner during fusing of electrophotographic prints
Sammanfattning : This licentiate thesis comprises two studies dealing withthe fusing step in electrophotographic printing. The firststudy addresses the development of a method for monitoringwetting/spreading of single toner particles in-situ on a heatedsubstrate. LÄS MER
2. Lubrication and Surface Properties of Adsorbed Layers of Polyelectrolytes and Proteins
Sammanfattning : Friction forces between protein / polyelectrolyte layers, adsorption properties of proteins, and conformational changes due to variation in electrolyte concentration have been investigated. The aim was to obtain better understanding of adsorbed layer properties, with focus on the relation between layer structure and lubrication capabilities. LÄS MER
3. Phosphorus Emissions from Fish Farms : Observed and Predicted Effects
Sammanfattning : During the last decades, fish farming has been a rapidly increasing industry in many European and North American countries. Sweden has a large potential for aquaculture, but there is also a strong concern about the effects on the environment that an increased aquaculture production may cause. LÄS MER
4. Biomarkers of vascular function and structure in young healthy adults
Sammanfattning : Atherosclerosis is a disease affecting the blood vessels in the body. Its pathophysiologic mechanisms involve infiltration of the vessel walls by fatty matter and immune cells. This process is slow, starting in childhood but typically not manifesting as symptomatic disease until late adulthood (after 60 years of age). LÄS MER
5. Utilizing Biopolymers in 3D Tumor Modeling and Tumor Diagnosis
Sammanfattning : Cancer represents a significant global public health challenge and ranks as the second mostcommon cause of death in the United States. The onset of cancer entails an initial phasewhere cells lose their polarity and disconnect from the normal basement membrane, allowingthem to form distinct three-dimensional (3D) configurations that interact with adjacent cellsand the surrounding microenvironment.
