  1. 1. Data preparation, hydrodynamic and contaminant transport shallow-water simulations of Lake Victoria

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Seema Paul; KTH.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake bathymetry model; Steady-state analysis; Numerical model validation; Lake water balance; Correlation and seasonal variations; Solute transport; Vattendjupskarta; Validering av numerisk modell; Vattenbalans; Korrelationer och säsongs-variation; Transport av lösliga ämnen; Mark- och vattenteknik; Land and Water Resources Engineering;

    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. 2. Polymer Bound Water-Soluble Metal Phosphine Complexes-Preparation, Characterisation and Catalytic Application

    Detta är en avhandling från Torsten Malmström. Inorganic chemistry 1, Chemical Center, Box 124, Lund University, 22100 Lund, Sweden

    Författare :Torsten Malmström; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enantioselective; SAP; hydrogenation; hydroformylation; catalysis; biphasic; rhodium; poly-ethylene imine; poly-acrylic acid; polymers; water-soluble; phosphines; Inorganic chemistry; Oorganisk kemi;

    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. 3. Plant-availability of phosphorus removed from wastewater by different processes

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Elisabeth Kvarnström; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    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. 4. Improved Molecular Understanding of Lipid-Based Formulations for Enabling Oral Delivery of Poorly Water-Soluble Drugs

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Linda C. Alskär; Uppsala universitet.; [2018]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipid-based formulation; poorly water-soluble drug; solubility prediction; molecular properties; lipid digestion; precipitation; solid state; intestinal solubilization; in vitro in vivo correlation IVIVC ; coadministration; Farmaceutisk vetenskap; Pharmaceutical Science;

    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

  5. 5. Microbial remediation of heavy metal ion polluted soil and water

    Detta är en avhandling från Avd. Bioteknik, Lunds Universitet

    Författare :Torbjörn Håkansson; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDTA; metal; soil; remediation; Sulphate reducing bactera; biogas; water;

    Sammanfattning : Contamination of soil and water by heavy metal ions (HMs) is a problem all over the world.The use of biological methods alone or in combination with other techniques for treatment of such polluted sites constitutes a major challenge. LÄS MER
