1. Aroma Partition and Release from Soft Drinks, Jam, and Jellied Sweets
Sammanfattning : The research described in the present thesis was focused on the influence of food ingredients and structures on the partition and release of aroma compounds from model systems such as soft drinks, jam, and jellied sweets. The effects on aroma release were studied during both static and dynamic conditions, the latter by both model mouth and in-nose measurements. LÄS MER
2. Diffusion studies in gels using holographic laser interferometry
Sammanfattning : This thesis is an investigation of the potential of holographic laser interferometry for the study of diffusion of both small solutes and macromolecules. An investigation on the importance of errors due to light deflection in refarctive index gradients showed that the magnitude of the refractive index gradients were negligible for the system investigated.

3. Metal Speciation and Toxicity in Sewage Sludge
Sammanfattning : Increasingly stringent controls on metal concentrations in sewage sludge destined for agricultural application provided a basis for the study of the relevance of metal speciation in sewage sludge. A comprehensive literature review identified difficulties in relating metal speciation through single chemical extractions to plant uptake and soil toxicity. LÄS MER

5. On Distribution Coefficients in Aquatic Systems
Sammanfattning : In this thesis, different types of chemical and physical distribution coefficients are identified, examined and used to describe the fate and transport pathways of substances in aquatic systems.Observations from field experiments in streams with non-reactive and reactive tracers constituted the basis for development of an advection-dispersion model.
