  2. 1. Timing Matters : Wounding and entomopathogenic nematode infection kinetics

    Author : Alexis Dziedziech; Ulrich Theopold; Angela Giangrande; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila melanogaster; Heterorhabditis bacteriophora; Photorhabdus luminescens; entomopathogenic nematodes; worms; high-resolution microscopy; time-lapse; infection; kinetics; sepsis; septic wounding; injury; clotting; glutactin; transglutaminase; prophenoloxidase; cell death; pyroptosis; caspase; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Over time, insects have developed complex strategies to defend themselves against presenting threats. However, in the evolutionary arms race of survival, pathogens have adapted to quickly overcome the immune response mounted by the host. READ MORE

  4. 2. Molecular Exchange in Colloidal Dispersions

    Author : Alex Evilevitch; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; charged micoremulsion droplets; kinetics; mechanism.; Physical chemistry; Fysikalisk kemi; molecular transport; cell model; infinite dilution limit; turbidity measurements; oil solubilization; computer simulation; modeling; monomer diffusion; molecular exchange; Microemulsion droplets; oil droplets;

    Abstract : This thesis is a study of molecular exchange between the aggregates in a colloidal dispersion. The problem of oil molecular transport at resolubilization of big oil drops by smaller microemulsion droplets is considered as an experimental model system. READ MORE

  5. 3. Lipase chemoselectivity - kinetics and applications

    Author : Cecilia Hedfors; Karl Hult; Mats Martinelle; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Candida antarctica lipase B; Rhizomucor miehei lipase; active site titration; kinetics; chemoselectivity; thiol; alcohol; thiol-functionalized polyesters; Biochemistry; Biokemi;

    Abstract :   A chemoselective catalyst is preferred in a chemical reaction where protecting groups otherwise are needed. The two lipases Candida antarctica lipase B and Rhizomucor miehei lipase showed large chemoselectivity ratios, defined as (kcat/KM)OH / (kcat/KM)SH, in a transacylation reaction with ethyl octanoate as acyl donor and hexanol or hexanethiol as acyl acceptor (paper I).

  6. 4. CO2 separation using ionic liquid-based absorbents : thermodynamics and kinetics

    Author : Yifeng Chen; Xiaoyan Ji; Xiaohua Lu; Marcus Öhman; Congmin Wang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic liquids; carbon dioxide; thermodynamics; kinetics; Energiteknik; Energy Engineering;

    Abstract : Ionic liquids (ILs) have shown great potential to be used as absorbents for CO2 separation owing to their unique properties such as immeasurably low vapour pressure, high thermal stability, high CO2 affinity, and tunable structure. A huge amount of researches have been carried out, and most of them focused on developing novel ILs for CO2 separation. READ MORE

  7. 5. The kinetics of cellulose enzymatic hydrolysis : Implications of the synergism between enzymes

    Author : Priit Väljamäe; Jan-Christer Janson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Acetobacter; Cellobiohydrolase; Cellobiose; Cellulase; Cellulose; Diffusion; Endoglucanase; Hydrolysis; Inhibition; Kinetics; Model; Product; Substrate; Surface; Synergism; Trichoderma reesei; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : The hydrolysis kinetics of bacterial cellulose and its derivatives by Trichoderma reesei cellulases was studied. The cellulose surface erosion model was introduced to explain the gradual and strong retardation of the rate of enzymatic hydrolysis of cellulose. READ MORE
