  1. 1. Structured Laser Illumination Planar Imaging SLIPI Applications for Spray Diagnostics

    Author : Elias Kristensson; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; signal attenuation; Multiple light scattering suppression; laser extinction; extinction coefficient; structured illumination; Fysicumarkivet A:2012:Kristensson;

    Abstract : Laser sheet imaging, also known as planar laser imaging, is one of the most versatile optical imaging techniques known and is frequently applied in several different domains. It furthermore constitutes the basis for a variety of other 2D methods, in turn allowing visualization of e.g. velocity, particle size, species concentration and temperature. READ MORE

  2. 2. Multi-Dimensional Quantitative Laser-based Diagnostics - Development and Practial Applications

    Author : Rikard Wellander; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Post injection; Structured illumination; Mie scattering; Dense sprays; Extinction coefficient; Signal attenuation; Laser extinction; Multiple scattering; Scattering measurements; Planar laser induced fluorescence; Time resolved; Imaging through turbulent media; Three-dimensional image acquisition; Diesel particulate filter regeneration; Wall impingent; Biodiesel; LII; Large-bore gas Engine; Pre-chamber ignition; Fysicumarkivet A:2014:Wellander;

    Abstract : Laser based optical diagnostic methods are routinely used in combustion research. Many of the more common approaches are based on illuminating a cross-section of the sample with a thin laser sheet. For example, by targeting an electronic transition in a molecule, its concentration within the plane illuminated by the laser sheet can be deduced. READ MORE

  3. 3. The Amygdala, Fear and Reconsolidation : Neural and Behavioral Effects of Retrieval-Extinction in Fear Conditioning and Spider Phobia

    Author : Johannes Björkstrand; Mats Fredrikson; Emily Holmes; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fear conditioning; phobia; memory reconsolidation; retrieval-extinction; exposure therapy; amygdala; fMRI; Psychology; Psykologi;

    Abstract : The amygdala is crucially involved in the acquisition and retention of fear memories. Experimental research on fear conditioning has shown that memory retrieval shortly followed by pharmacological manipulations or extinction, thereby interfering with memory reconsolidation, decreases later fear expression.

  4. 4. Genetic gating of human fear, fear learning and extinction : psychophysiological, brain imaging (fMRI) and clinical studies

    Author : Tina B Lonsdorf; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Individuals differ in their reaction to the same environmental stressor. After being opposed to the same trauma, some individuals will develop affective pathologies, while others will not. This is assumed to result, at least partly, from a differential genetic vulnerability. READ MORE

  5. 5. Design and Synthesis of Chalcone and Chromone Derivatives as Novel Anticancer Agents

    Author : Christine Dyrager; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chalcones; Chromones; Fluorescence; Fluorophore; Cellular imaging; Anticancer; Tubulin; Microtubule; Kinase inhibitors; p38; MEK1; Palladium-mediated reactions; Molecular modeling; Structure-Activity Relationships.;

    Abstract : This thesis comprises the design and synthesis of chalcone and chromone derivatives and their use in various biological applications, particularly as anticancer agents (targeting proteins associated with cancer pathogenesis) and as potential fluorophores for live-cell imaging. Conveniently, all structures presented were synthesized from commercially available 2 ́-hydroxyacetophenones. READ MORE
