  2. 6. Ultrasound Contrast Agents Loaded with Magnetic Nanoparticles : Acoustic and Mechanical Characterization

    Author : VeeraVenkata Satyanarayana Kothapalli; Lars-Åke Brodin; Jan Engvall; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound contrast agents; SPION nanoparticles; harmonic oscillation; backscattering power; attenuation coefficient; phase velocity; nonlinear equation of motion;

    Abstract : The current methodologies in body scanning diagnostic uses different simultaneous imaging modalities like Ultrasound (US), magnetic resonance imaging (MRI), single photon emission tomography (SPECT) and positron emission tomography (PET). The field requires combination of different modalities for effective use in clinical diagnostics. READ MORE

  4. 7. Computer simulations of electronic energy transfer and a molecular dynamics study of a decapeptide

    Author : Maria Lindberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electronic energy transfer; Monte Carlo simulations; two-particle model; GAF-theory; anisotropic systems; fluorescence depolarization ratios; Brownian Dynamics; rotating donors; Molecular Dynamics; peptide; renin inhibitor;

    Abstract : Electronic energy transfer has been investigated in pure donor systems by means of computer simulations. Calculated properties were the probability that the initially excited donor is excited at a time t after the excitation, Gs(t), the mean square displacement of the excitation and different fluorescence observables.

  6. 9. Interpretation of diagnostic information given patient characteristics

    Author : Martin Gellerstedt; Hans Åhlfeldt; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; reference values; diagnostic theory; diagnostic tests; partitioning; prevalence function; reference values; diagnostic theory; diagnostic tests; partitioning; prevalence function;

    Abstract :  The aim with this thesis was to describe, exemplify and develop theory for reference values and diagnostic tests, especially focusing on the variability between individuals. To facilitate interpretation of medical information it is common to establish some kind of limit. There are several different rationales for the choice of such a limit. READ MORE
