  1. 1. 3D localization in digital holography from scattered light from micrometer-sized particles

    Author : Johan Öhman; Mikael Sjödahl; Per Bergström; Erik Olsson; Torbjörn Löfqvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Holography; Polarization; Particle Scattering; Metrology; Experimentell mekanik; Experimental Mechanics;

    Abstract : When a particle is illuminated by a beam of light it will scatter and redistribute the light in all directions. How it scatters depends on the size, shape and refractive index of the particle. Additionally, it depends on the wavelength and polarization of the illuminating beam. READ MORE

  2. 2. Polarization-Resolved Particle Holography

    Author : Johan Öhman; Mikael Sjödahl; Erik Olsson; Per Bergström; Pietro Ferraro; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimentell mekanik; Experimental Mechanics;

    Abstract : In this thesis, measurement of particle fields using digital holography is the main subject. The questions investigated consider positioning, identification and sizing of nanometer and micrometer particles. The thesis explore these topics using both simulations and experimental measurements.

  3. 3. Upscaling of Flow, Transport, and Stress-effects in Fractured Rock

    Author : Johan Öhman; Auli Niemi; Ove Stephansson; Robert W Zimmerman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Upscaling; fractured media; flow; solute transport; thermo-hydro-mechanical processes; hybrid approach; continuum approximation; discrete fracture network; stochastic continuum; Hydrologi; Hydrology; Hydrologi;

    Abstract : One of many applications of geohydraulic modelling is assessing the suitability of a site to host a nuclear waste repository. This modelling task is complicated by scale-dependent heterogeneity and coupled thermo-hydro-mechanical (THM) processes. READ MORE

  4. 4. Novel sites of A-to-I RNA editing in the mammalian brain

    Author : Johan Ohlson; Marie Öhman; Robert Reenan; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : The number of protein-coding genes are likely not sufficient to account for the complexity of higher organisms. It is plausible that the proteome is responsible for the complexity of an organism. READ MORE

  5. 5. The Responsible Business Person : Studies of business education for sustainability

    Author : Pernilla Andersson; Magnus Boström; Jenny Gunnarsson-Payne; Johan Öhman; Malin Ideland; Södertörns högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; education; sustainable development; responsibility; environment; business; curriculum; teaching; discourse analysis; poststructuralism; pedagogy; classroom; Environmental Studies; Miljövetenskapliga studier;

    Abstract : Calls for the inclusion of sustainable development in the business curriculum have increased significantly in the wake of the financial crisis and increased concerns around climate change. This has led to the appearance of new initiatives and the development of new teaching approaches. READ MORE
