  1. 1. Trichoderma viride alamethicin and plant cells - Action, response and resistance

    Author : Mari Aidemark; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; Nicotiana tabacum; cell cultures; alamethicin; cell permeabilisation; resistance; callose; BY-2;

    Abstract : Alamethicin is a membrane active peptide secreted from the soil-living fungus Trichoderma viride. When coexisting with T. Viride, plant roots are exposed to alamethicin, which has the ability to elicit formation of volatile compounds involved in pathogen defence. READ MORE

  2. 2. Macromolecular interactions, Consequences on carbohydrate metabolism

    Author : Sandra Matic; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; macromolecular interactions; sucrose synthase; macromolecular crowding; cytoskeleton; BY-2 tobacco cells; alamethicin; aqueous polymer two-phase partitioning;

    Abstract : Most cells are crowded with solutes, enzymes, nucleic acids, structural proteins and membranes. Crowding promotes macromolecular interactions and determines major properties of the cellular environment such as viscosity, diffusion and inhomogeneity. READ MORE

  3. 3. Piezoelectric and ferroelectric device technologies for microwave oscillators

    Author : Martin Norling; Chalmers University of Technology; []
    Keywords : piezoelectrics; electrostrictive materials; microwave oscillators; thin film devices; ferroelectrics; thin film bulk acoustic resonators; ferroelectric varactors;

    Abstract : The purpose of this thesis is to investigate piezoelectric and ferroelectric thin film device technologies for application in microwave oscillators.Thin film varactors based on ferroelectric materials are considered. READ MORE

  4. 4. Methylsulphonyl-chlorobenzenes and the olfactory system : Comparative toxicity of the 2,5- and 2,6-dichlorinated isomers in mice

    Author : Fariba Bahrami; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; toxikologi; Toxicology;

    Abstract : Methyl sulphone metabolites of chlorinated aryl hydrocarbons are persistentenvironmental pollutants that can bioaccumulate in animals and humans. Little is known about the toxicological effects of these metabolites and this thesis is an attempt to increase this limited knowledge. READ MORE

  5. 5. Robust preconditioned iterative solution methods for large-scale nonsymmetric problems

    Author : Erik Bängtsson; Maya Neytcheva; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

    Abstract : We study robust, preconditioned, iterative solution methods for large-scale linear systems of equations, arising from different applications in geophysics and geotechnics.The first type of linear systems studied here, which are dense, arise from a boundary element type of discretization of crack propagation in brittle material.
