  2. 16. The effects of solid state properties on solubility and "in vitro" dissolution behaviour of suspended sparingly soluble drugs

    Author : Mitra Mosharraf; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

    Abstract : The solubility and dissolution behaviour of hydrophobic and hydrophilic sparingly soluble drugs is discussed in this thesis. The roles of varying particle dimensions, disordered (amorphous) solid structures and the coexistence of amorphous and crystalline phases, especially on the surfaces of particles with a crystalline core, are evaluated in this context.

  4. 17. Seasonal variation of road runoff in cold climate

    Author : Camilla Westerlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : The main objective of this thesis was to characterize and study the behaviour and transport of pollutants, i.e., suspended solids, particles and heavy metals, in road runoff from a small urban catchment during snowmelt and rainfall. READ MORE

  5. 18. Particle concentrations : analysis methods for urban runoff

    Author : Kerstin Nordqvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Urban runoff often contains high concentrations of particles. Pollutants that adsorbs to surfaces of particulate material will be transported to receiving waters or a sewage treatment plant. For the recipient, the particles in the runoff are a significant cause of water quality impairment. READ MORE

  6. 19. Influence of hydrochemical parameters on the mobility and redistribution of metals from a mine waste deposit

    Author : Stefan Karlsson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The aim of the research presented in this thesis has been to combine theoretical and empirical methods to describe chemical attenuation of trace metals (i.e. Al, Cd, Cu, Fe, Mn, Pb and Zn) in a polluted watershed. It was possible to elucidate the major mechanisms by using the naturalvariations of chemical composition of the system. READ MORE

  7. 20. Microsieving in municipal wastewater treatment : Chemically enhanced primary and tertiary treatment

    Author : Janne Väänänen; Avdelningen för kemiteknik; []
    Keywords : coagulation; wastewater treatment; flocculation; microsieving; control; primary treatment; tertiary treatment; coagulation; control; flocculation; microsieving; municipal wastewater treatment; primary treatment; tertiary treatment;

    Abstract : Municipal wastewater treatment plants are constantly forced to make improvements. The main objectives are to reduce energy consumption, to increase the treatment capacity and to improve the effluent water quality. Microsieves in combination with chemical pretreatment can potentially fulfil these objectives. READ MORE
