  2. 6. Measuring Material Properties through Gradient Based NMR: Diffusion and Imaging

    Author : Ingrid Åslund; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intracellular diffusion; homogeneous length-scale; material properties; emulsions; yeast suspensions; lamellar phase; NMR; self-diffusion; membrane permeability and bending rigidity;

    Abstract : In this work new methods based Nuclear Magnetic Resonance (NMR) have been developed to measure different kinds of structural properties in soft materials. The advantage of using NMR as a technique to measure material properties is that it is non-destructive, which makes it possible to measure on the actual piece of material that will be used for the application.

  4. 7. Small-Animal Imaging with Liquid-Metal-Jet X-Ray Sources

    Author : Daniel Larsson; Hans Hertz; Anna Burvall; David Paterson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray; x-ray imaging; small animal; phase contrast; tomography; Fysik; Physics;

    Abstract : Small-animal x-ray imaging is an important tool for medical research. The penetration power of x-rays makes it possible to investigate the 3D structure of small animals and other thick biological samples by computed tomography (CT). READ MORE

  5. 8. Properties of Type Ia Supernovae : From the (intermediate) Palomar Transient Factory

    Author : Seméli Papadogiannakis; Ariel Goobar; Rahman Amandius; Ulrich Feindt; Edward Baron; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Type Ia supernovae; cosmology; machine learning; fysik; Physics;

    Abstract : Type Ia Supernovae (SNe) have been used to discover the accelerated expansion of the universe but many open questions remain unanswered. These include the stellar progenitor, extinction and possible systematic trends in the supernova brightness for different host galaxy environments or cosmic time. READ MORE

  6. 9. Some aspects of statistical inference in systems of equations

    Author : Ghazi Shukur; Statistiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; small sample properties.; misspecification; system of equations; dynamic specification; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : The objective of this thesis is to develop a strategy for statistical/econometric inferences applicable to systemwise testing of econometric models. A common deficiency in many applied econometric studies is the absence of statistical diagnostic testing. READ MORE

  7. 10. Small Particles with Big Impact : Structural Studies of Viruses and Toxicological Studies of Nanodiamonds

    Author : Anna Munke; Marvin Seibert; Kenta Okamoto; Filipe Maia; Inger Andersson; Nicola Stonehouse; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chaetenuissarnavirus II; cryo-EM; CtenRNAV-II; Escherichia coli; Danio rerio; flash X-ray imaging; Marnaviridae; single-particle analysis; single-particle imaging; Sogarnavirus; virus evolution; virus structure; XFEL; zebrafish embryo; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Nanoparticles (NPs) can be found everywhere and their existence has both beneficial and harmful consequences for the environment and living beings. The investigations on which this thesis is based upon have contributed to an increased understanding of some of these particles and to the development of a method that could be used to study their structure.
