2. 1. Alkylglycoside Surfactants - Self-Assembly, Solid-State Properties and Interactions with Hydrophobic Molecules

   Author : Caroline Ericsson; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; peptide stabilisation; solubilisation; micelle morphology; solid-state behaviour; alkylglycosides; nonionic surfactants;

   Abstract : A thorough physical-chemical characterisation of alkylglycosides has been performed. The effects of temperature, salt, concentration and deuterium exchange on the self-aggregation of n-nonyl-b-D-glucoside (b-C9G1) and n-tetradecyl-b-D-maltoside (b-C14G2) have been studied in dilute solutions by static and dynamic light scattering, neutron scattering, rheology, capillary viscometry and tensiometry.

4. 2. Adsorption of nonionic amphiphiles to solid surfaces

   Author : Johanna Brinck; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; silica; solubilisation; self assembly; ellipsometry; mixed micelles; surfactant; kinetics; Adsorption; desorption; Fysikalisk kemi;

   Abstract : In this study, the adsorption of nonionic amphiphiles from aqueous solutions to solid, planar surfaces is investigated using null ellipsometry. This technique allows independent measurements of the amounts adsorbed at the surface and of the mean optical thickness of the adsorbed layer. READ MORE

5. 3. Ectomycorrhizal community structure and function in relation to forest residue harvesting and wood ash applications

   Author : Shahid Mahmood; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; 14C allocation; P uptake; Calcium oxalate; Solubilisation; Tricalcium phosphate; Wood ash; Forest residue; N deposition; rDNA; ITS region; PCR-RFLP; Spruce; Ectomycorrhiza; Community structure; Wood ash colonisation; Spruce colonisation; Competition; Ecology; Ekologi;

   Abstract : Ectomycorrhizal fungi form symbiotic associations with tree roots and assist in nutrient-uptake and -cycling in forest ecosystems, thereby constituting a most significant part of the microbial community. The aims of the studies described in this thesis were to evaluate the potential of DNA-based molecular methods in below-ground ectomycorrhizal community studies and to investigate changes in ectomycorrhizal communities on spruce roots in sites with different N deposition, and in sites subjected to harvesting of forest residues or application of wood ash.

6. 4. Characterisation of Dietary Fibre Properties to Optimise the Effects on Human Metabolism and the Transcriptome

   Author : Matilda Ulmius; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; field-flow fractionation; gastrointestinal method; aggregation; solubilisation; pectin; β-glucan; sugar beet fibre; Oats; rye; postprandial responses; microarray gene expression;

   Abstract : It is well established that dietary fibre, especially soluble dietary fibre, has beneficial effects and can prevent diseases associated with the modern lifestyle. This has been explained by the viscous effects of soluble fibre, which can reduce or delay the absorption of carbohydrates and fat in the small intestine, resulting in lower blood concentrations of glucose, insulin and cholesterol.

7. 5. Soluble and Plant Available Phosphorus in Acid Soils

   Author : Ann-Mari Fransson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; solubilisation mechanisms; Phosphorus extractions; Oxalate extraction; P fertilisation; Plant ecology; Växtekologi;

   Abstract : The P availability and solubility differ between soils and plants seem to have different ways of utilising the P present. The many P fractions present in soil interact and are closely related to another and transformations may easily occur. Due to this more P than the soluble fraction is available to plants. READ MORE
