  1. 11. NMR studies of the amyloid beta-peptide

    Författare :Jens Danielsson; Astrid Gräslund; Chris Dobson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR; amyloid beta peptide; structure; metal interaction; diffusion; Biophysics; Biofysik;

    Sammanfattning : The Amyloid beta peptide (Ab) is related to Alzheimer’s disease and is suggested to be the molecular pathogenic species of the disease, probably through the neurotoxic effect of Ab oligomers. Here the results from biophysical studies of Ab and fragments thereof, are presented. LÄS MER

  3. 12. Experiments with and modelling of explosively driven mangetic flux compression generators

    Författare :Patrik Appelgren; Nils Brenning; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic Flux Compression; Explosives; Pulsed Power; Circuit Simulations; Hydrodynamic simulations; Electrophysics; Elektrofysik;

    Sammanfattning : This thesis presents work performed on explosively driven magnetic flux compression generators. This kind of devices converts the chemically stored energy in a high explosive into electromagnetic energy in the form of a powerful current pulse. LÄS MER

  4. 13. Elasto-hydrodynamic film formation in heavily loaded rolling-sliding contacts : Influence of surface topography on the transition between lubrication regimes

    Författare :Jonny Hansen; Roland Larsson; Marcus Björling; Guillermo Morales-Espejel; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : To meet the stringent demands set on future gear transmissions, and to allow for manufacturers to make them more efficient and durable, it is essential to understand what mechanisms that govern their performance. This work was launched with the chief targets of establishing key competence in gear lubrication. LÄS MER

  5. 14. Blue-green stormwater systems for citywide flood mitigation : Monitoring, conceptualization, modeling, and evaluation

    Författare :Salar Haghighatafshar; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blue-green measures; drainage system; flooding; flood mitigation; hydrodynamic modeling; rainfall-runoff; stormwater;

    Sammanfattning : Considering the growth in urbanization, leading to an increase in impervious surfaces, and the changing climate, enhancing the intensity and frequency of rainfall events, existing urban drainage networks—separate or combined sewer systems—are presumed to face substantially elevated hydraulic loads, causing pluvial floods in urban areas. There are several ways to address these challenges. LÄS MER

  7. 15. Propeller-Hull Interaction Effects in Calm Water and Regular Head Waves

    Författare :Mohsen Irannezhad; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RANS; Resistance; Thrust Deduction Factor; Self-Propulsion Point of Model; CFD; Regular Head Waves; Nominal Wake; Ship Motions; Taylor Wake Fraction; Propeller Open Water Characteristics; EFD; FNPF;

    Sammanfattning : In order to design fuel-efficient ships and install compatible propulsion systems, ship and propeller designers need to know the potential effects of the interactions between different ship components, e.g., hull, propeller, appendages and machinery, on the ship performance at sea.
