  1. 1. Laboratory Seismic Testing of Asphalt Concrete

    Author : Anders Gudmarsson; Nils Rydén; Björn Birgisson; Hervé Di Bendetto; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Nondestructive laboratory seismic testing to characterize the complex modulus and Poisson’s ratio of asphalt concrete is presented in this thesis. These material properties are directly related to pavement quality and the dynamic Young’s modulus is used in thickness design of pavements. READ MORE

  2. 2. Time dependent material properties of shotcrete for hard rock tunnelling

    Author : Lars Elof Bryne; Anders Ansell; Wolfgang Kusterle; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shotcrete; rock; granite; bond strength; compressive strength; pullout testing; failure modes; interfacial transition zone; micro structure; ettringite; set accelerator; shrinkage; drains; glass fibres; laboratory testing; tunnels tunnelling;

    Abstract : In this thesis different mechanical properties for shotcrete (sprayed concrete) such as compression strength, bond strength, bending tensile strength, elastic modulus, free and restrained shrinkage as a function of its age was investigated. One of the main issues was to investigate the difference between ordinary cast concrete and shotcrete. READ MORE

  3. 3. Molecular and serological tools for clinical diagnostics of Lyme borreliosis - can the laboratory analysis be improved?

    Author : Malin Lager; Anna J. Henningsson; Peter Wilhelmsson; Per-Eric Lindgren; Andreas Matussek; Fredrik Elgh; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Lyme borreliosis (LB) is caused by spirochetes within the Borrelia burgdorferi sensu lato complex and is the most common tick-transmitted disease in the northern hemisphere. The transmission of the spirochetes to humans in Europe is done by the Ixodes ricinus ticks, which can also transmit the relapsing fever species Borrelia miyamotoi. READ MORE

  4. 4. Miniaturised Microwell-based Cell Assays

    Author : Emilie Weibull; Helene Andersson Svahn; Albert van den Berg; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microwell; miniaturisation; high-resolution imaging; high-throughput; cell culture; single-cell; clone; heterogeneity; antibiotic susceptibility testing; concentration gradient; interfacing; microchannels; cell retrieval;

    Abstract : Cell heterogeneity in genetically identical cell populations is becoming a well-known and important phenomenon in cell biology. Current methods commonly utilise population-based analysis founded on averaged result. Hence there is a need for high-throughput cell assays on the single-cell level. READ MORE

  5. 5. Resonance Testing of Asphalt Concrete

    Author : Anders Gudmarsson; Nils Rydén; Björn Birgisson; Mihai Marasteanu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resonance frequencies; Modal testing; Frequency response functions; Cyclic loading; Tension-compression tests; Complex modulus; Complex Poisson’s ratio;

    Abstract : This thesis present novel non-destructive laboratory test methods to characterize asphalt concrete. The testing is based on frequency response measurements of specimens where resonance frequencies play a key role to derive material properties such as the complex modulus and complex Poisson’s ratio.
