  1. 16. Evaluation of in vitro antagonism assays in the mycoparasitic fungus Clonostachys rosea

    Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Victor Olsson; [2020]
    Nyckelord :Biocontrol; Biocontrol agent; Clonostachys rosea; Fusarium gramine-arum;

    Sammanfattning : Fungicide use is the dominant direct method to control fungal pathogens on crops in agriculture. While effective, excessive use of them can be harmful to biodiversity and lead to fungicide resistance in pathogen populations. Biocontrol is an alternative where natural antagonistic organisms, called biocontrol agents (BCA), are used to protect crops. LÄS MER

  3. 17. Secondary aerosol formation from dimethyl sulfide - Smog chamber experiments and detailed process modelling

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Dana Lüdemann; [2020]
    Nyckelord :aerosol modelling; atmospheric physics and chemistry; marine aerosols; ADCHAM; aerosol; dimethyl sulfide; Physics and Astronomy;

    Sammanfattning : The aim of this thesis was to investigate the secondary aerosol formation from dimethylsulfide (DMS) using the aerosol dynamics, gas- and particle-phase chemistry kinetic multi-layer model, ADCHAM. The first simulations, concerning the butanol oxidation via hydroxyl radicals (OH), were performed to characterize the UV-light source of the AURA smog chamber (Aarhus university, Denmark), later used for the DMS experiments.

  4. 18. Combining biocontrol fungus Clonostachys rosea with chemical fungicides – for integrated management of Fusarium foot/root rot

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Sebastian Bengtsson; [2020]
    Nyckelord :Biocontrol agent; Clonostachys rosea; Fusarium culmorum; Fusarium graminearum; prothioconazole; Proline; Fusarium foot root rot; ; Integrated pest management;

    Sammanfattning : Fungal plant diseases have typically been controlled by the application of chemical pesticides. However, excessive use of chemical pesticides may produce undesirable side effects including fungicides tolerance in pathogens and environmental problems, if not handled correct. LÄS MER

  5. 19. Stress-free titanium-based thin films for inner ear microphones : The last missing part of a technology for totally implantable hearing aid implants

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Dina Ehsan; [2020]
    Nyckelord :Stress-free; thin films; in situ; titanium; compressive; tensile;

    Sammanfattning : An implantable hearing aid device is being developed by a project group which is part of an EU initiative. This device contains a diaphragm consisting of a submicron thick freestanding titanium film, which should be free of internal stresses. LÄS MER

  7. 20. Examining the competitive abilities of cornflower (Centaurea cyanus) in a growth chamber experiment.

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Emil Karlsson; [2019]
    Nyckelord :Centaurea cyanus; Papaver rhoeas; Avena sativa; Cornflower; Growth chamber; Plant competition; Plant ecology; LAI; Root biomass; Root length; Biomass; Dry weight; Interspecific competition; Blåklint; Kärlväxter; Konkurrensförmåga; Ekologi;

    Sammanfattning : Competition between different species (interspecific competition) is an important factor to consider when estimating population trends, geographic distributions, and management options of species. Many historically common vascular plant species found in agricultural environments have been negatively affected by changes in community composition and in turn, changes in competition pressures.
