  1. 11. An Analysis of NMRD profiles and ESR lineshapes of MRI Contrast Agents

    Författare :Xiangzhi Zhou; Per-Olof Westlund; Jozef Kowalewski; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; MRI contrast agent; MS-325; Spin relaxation; NMRD; ESR; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : To optimize contrast agent in MRI scan region, e.g. to enhance paramagnetic relaxation in the MRI scan fields(0.1T-3T), one possible way is to slow down the tumbling of the paramagnetic complex. LÄS MER

  3. 12. Form and function of complex networks

    Författare :Petter Holme; Beom Jun Kim; Mark Newman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; complex networks; complexity; small-world networks; scale-free networks; graph theory; Teoretisk fysik; Physics; Fysik; teoretisk fysik; Theoretical Physics;

    Sammanfattning : Networks are all around us, all the time. From the biochemistry of our cells to the web of friendships across the planet. From the circuitry of modern electronics to chains of historical events. A network is the result of the forces that shaped it. LÄS MER

  4. 13. Exploring the surface of aqueous solutions : x-ray photoelectron spectroscopy studies on a liquid micro-jet

    Författare :Josephina Werner; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The surface behavior of biologically or atmospherically relevant chemical compounds in aqueous solution has been studied using surface-sensitive X-ray photoelectron spectroscopy (XPS). The aim is to provide information on the molecular-scale composition and distribution of solutes in the surface region of aqueous solutions. LÄS MER

  5. 14. Numerical Simulations of Plasmonic Nanostructures

    Författare :Joan Alegret; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoholes; DDA; Green s tensor; nanostructures; surface plasmons;

    Sammanfattning : This thesis focuses on the study of metallic nanostructures that support plasmons. Special emphasis is devoted to two specific numerical methods that allow us to predict plasmon characteristics: the discrete dipole approximation (DDA) and the Green's tensor (GT) method. LÄS MER

  7. 15. Nutrition, exercise and body composition in community-dwelling older adults : Effects on function, wellbeing and mortality

    Författare :Åsa von Berens; Tommy Cederholm; Afsaneh Koochek; Margaretha Nydahl; Peter Nordström; Uppsala universitet; []
    Nyckelord :Older adults; function; nutrition; wellbeing; mortality; exercise; sarcopenic obesity;

    Sammanfattning : Background: The demographic shift in society with more people reaching a high age provides new challenges for both society and the healthcare system.Aim: The overall aim of this thesis was to examine the impact of nutrition, exercise and body composition on function, wellbeing and mortality in community-dwelling older adults.
