  1. 11. Fluid Dynamics of Fluidized Bed Reactors: Experiments and Simulations with System Interactions

    Författare :Srdjan Sasic; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Air-supply system; Interaction; Fluidized bed; Pressure waves; Pressure fluctuations;

    Sammanfattning : This thesis is a study of the interaction between the fluidized-bed dynamics and the pressure and flow pulsations from the air-supply system. The interaction has been identified as a key process to understand in order to correctly formulate inlet boundary conditions in numerical modelling of fluidized beds, operated under industrial conditions.

  3. 12. In vitro Pharmacodynamics of Antifungal Agents in the Treatment of Candida Infections

    Författare :Anders Lignell; Jan Sjölin; Elisabeth Löwdin; Mats Kalin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amphotericin B; antagonism; Candida; human serum; inhibition; interaction; in vitro; kinetic model; pharmacodynamics; pharmacokinetics; posaconazole; protein binding; voriconazole; Infectious diseases; Infektionssjukdomar; Infektionssjukdomar; Infectious Diseases;

    Sammanfattning : Pharmacodynamic studies are important for the optimal use of antimicrobial agents. Combination antifungal therapy may be one method to improve outcome in invasive Candida infections. LÄS MER

  4. 13. Structure-Reactivity Correlations for Reactions of Palladium(II) and Platinum(IV) Complexes

    Författare :Tiesheng Shi; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thiol; l-methionine; maleic acid; carboxylic acid; thioether; platinum IV ; palladium II ; linear free energy relationship; volumes of activation; structure-reactivity correlation; reduction; substitution; equilibria; kinetics; mechanism; glutathione; Animal physiology; Djurfysiologi;

    Sammanfattning : The kinetics and mechanism for substitution reactions on tetraaquapalladium(II) by an extended series of thioethers, a great number of carboxylic acids, and olefins have been studied by use of UV-VIS, stopped-flow, and high-pressure stopped-flow spectrophotometry and NMR spectroscopy. Second-order rate constants k and activation parameters (activation enthalpies, entropies, and volumes) for formation of monodentate 1:1 complexes have been determined. LÄS MER

  5. 14. Interfacial Properties of Lipid Liquid Crystalline Nanoparticles

    Författare :Pauline Vandoolaeghe; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; interaction; adsorption; surface; peptide; bilayer; cubic phase; monoolein; cubosome; lipid; liquid crystalline nanoparticles; ellipsometry; neutron reflectivity; QCM-D; SAXD;

    Sammanfattning : Lipid liquid crystalline nanoparticles are studied for their potential as biocompatible carriers for pharmaceutical, food and cosmetic applications. Their potential as delivery vehicles is due to their nanometer size, their controllable structure and physical properties and their large carrying capacity of a wide range of molecules. LÄS MER

  7. 15. Model Systems for Metal - DNA Interactions. With a Focus on Anticancer Active Platinum(II) Complexes

    Författare :Anna Ericson; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kinetics; DNA; poly d T ; guanine; 6-thioinosine-5 -monophosphate; 6-thio-2 -deoxyinosine; 4-thiouridine-5 -monophosphate; 4-thio-2 -deoxyuridine; palladium II ; Gold III ; platinum II ; mechanism; salt effect; activation parameters; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Reactions of trans-dicyanodichloroaurate(III) trans-dibromodicyanoaurate(III), trans-diamminedichlorogold(III), cis-diammine(aqua)chloroplatinum(II), cis-ammineaqua-(cyclohexylamine)chloroplatinum(II), chloro(terpyridine)platinum(II) and chloro-(diethylenetriaminepalldium(II) with dimethyl sulfide, thionucleosides, thionucleotides and thione- and guanine-containing 17-mer oligonucleotides have been investigated by use of conventional and high-pressure stopped-flow spectrophotometry and HPLC technique as a function of ionic strength, pH, temperature and pressure in aqueous solutions. The mechanism and rate of oxidation of dimethyl sulfide by gold(III) complexes depends on the concentration of free halide. LÄS MER
