1. Data preparation, hydrodynamic and contaminant transport shallow-water simulations of Lake Victoria
Sammanfattning : This study explores shallow lake numerical hydrodynamic processes that support model development and validation, extreme events and effects of water circulation in Lake Victoria. Lake Victoria is the second largest freshwater lake in the world, and the largest in East Africa. LÄS MER
2. Polymer Bound Water-Soluble Metal Phosphine Complexes-Preparation, Characterisation and Catalytic Application
Sammanfattning : Four new water-soluble phosphines have been prepared by utilising water-soluble polymers as charge carrying units. Coupling of methyl-4-(diphenylphosphino)-benzyl-amine or 4-diphenylphosphino benzaldehyde to poly-acrylic acid and poly-ethylene imine, respectively, afford the ligands PAA-PNH and PEI-PNH. LÄS MER
3. Plant-availability of phosphorus removed from wastewater by different processes
Sammanfattning : The objective of this thesis was to investigate the plant-availability of P removed from wastewater by different processes, with focus on agronomic aspects. Short-term P availability was assessed by greenhouse studies, utilizing four different filter substrates and a sludge-recovered iron phosphate. LÄS MER
4. Organic micropollutants in highway stormwater and the role of a gross pollutant trap-biofilter stormwater treatment train
Sammanfattning : The studies which this thesis is based on assessed the stormwater quality in a highway catchment located in Sundsvall, Sweden, and examined the performance of a gross pollutant trap (GPT)-biofilter stormwater treatment train (TT) downstream of the catchment, in terms of removal efficiency, intra-event variability, and environmental risk reduction of organic micropollutants (OMPs) for the receiving water body. Assessing the occurrence and event mean concentrations (EMCs) of all OMPs in the catchment revealed that bisphenol A (BPA), octylphenol (OP), nonylphenol (NP), five carcinogenic and four non-carcinogenic polycyclic aromatic hydrocarbons (PAHs), and C16-C40 fractions of petroleum hydrocarbons (PHCs) all potentially pose an environmental risk to freshwater (EMCs >PNEC: predicted non-effect concentration), while alkylphenolethoxylates, six low- molecular weight PAHs, and lighter fractions of PHCs (C10-C16) do not occur at problematic levels.

5. Improved Molecular Understanding of Lipid-Based Formulations : for Enabling Oral Delivery of Poorly Water-Soluble Drugs
Sammanfattning : The majority of emerging drug candidates are not suited for conventional oral dosage forms, as they do not dissolve in the aqueous environment of the gastrointestinal (GI) tract. Consequently, a large number of enabling formulation strategies have emerged. LÄS MER
