  2. 1. SPECT Imaging using Pinhole Collimation : System Design and Simulation Studies for Pre-Clinical and Clinical Imaging

    Author : Mikael Peterson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pinhole SPECT tomography; Nuclear medicine imaging; Monte Carlo-based image reconstruction;

    Abstract : The focus of this dissertation is the use of pinhole collimation in Nuclear Medicine. A pinhole is a single aperture in an opaque material that is placed between the detector and source of interest, and photons must pass through the hole to reach the detector. The choices of pinhole parameters, e.g. READ MORE

  4. 2. Assessment of shear and energy‐absorption capacity of reinforced concrete elements under impulsive loads

    Author : Viktor Peterson; Anders Ansell; Mikael Hallgren; Yanyan Sha; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Impulsive loads; impact; blast; shear reinforcement; shear failure; Betongbyggnad; Concrete Structures;

    Abstract : Impulsive loads have been observed to cause brittle shear failure in reinforced concrete elements designed for ductile failure modes under static loads. Brittle failure modes exhibit poorer energy absorption capabilities compared to ductile flexural failure modes due to their limited deformation capacity, leading to premature failure. READ MORE

  5. 3. Biophysical Characterization of Thiopurine S-Methyltransferase : A Key enzyme in the Effects of Thiopurine Drugs

    Author : Patricia Wennerstrand; Lars-Göran Mårtensson; Curt Peterson; Malin Lindqvist Appell; Mikael Widersten; Linköpings universitet; []
    Keywords : ;

    Abstract : In the treatment of leukemia and inflammatory bowel disease, thiopurines are commonly used drugs. Thiopurine S-methyltransferase (TPMT) is one of the drug metabolizing enzymes responsible of counteracting the formation of TGNs that will be incorporated into the DNA and RNA synthesis and thus induce apoptosis.
