  1. 6. Processing of berries – Effects on functionality, stability and bioactivity of anthocyanins

    Författare :Gabriel Barbosa; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; berries; powder; hot air and microwave drying; osmotic dehydration; press cake; edible coating; anthocyanins; gastrointestinal in vitro digestion; polyphenols; pulsed electric field; oxidative stress; yeast;

    Sammanfattning : Berries are rich natural sources of anthocyanins, water-soluble pigments in plants that have been linked to beneficial effects against chronic diseases, such as cardiovascular diseases, type 2 diabetes and neurodegenerative diseases. However, anthocyanins as well as other polyphenolic compounds are often sensitive to degradation during processing, storage and digestion. LÄS MER

    Sammanfattning : Theories for microwave breakdown in gases, with emphasis on Air, are presented in this thesis. Underlying physical processes are described together with models suitable for scientific research and technical development. LÄS MER

  4. 8. The Polar Cusp and its Ionospheric footprint : Dynamics and Transients

    Författare :Frédéric Pitout; Ryoichi Fujii; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; Solar wind - magnetosphere - ionosphère interactions; polar ionosphere; Rymd- och plasmafysik; Space physics; Rymdfysik; Space Physics; rymdfysik;

    Sammanfattning : The magnetopause, the boundary layer between the solar wind and the Earth’s magnetosphere, is not closed as we have long thought. Transfers of energy, particles and momentum from the solar wind to the magnetosphere actually take place. LÄS MER

  5. 9. Characterizing ions in solution by NMR methods

    Författare :Marianne Giesecke; István Furó; Peter Griffiths; KTH; []
    Nyckelord :electrophoretic NMR; diffusion NMR; NMR imaging; ion pairing; ion association; polyethylene oxide; metal-ion complex; Li ion batteries; electrolyte characterization; Kemi; Chemistry;

    Sammanfattning : NMR experiments performed under the effect of electric fields, either continuous or pulsed, can provide quantitative parameters related to ion association and ion transport in solution.  Electrophoretic NMR (eNMR) is based on a diffusion pulse-sequence with electric fields applied in the form of pulses.

  7. 10. Etiological and clinical aspects of skin sensivity

    Författare :Sol-Britt Lonne-Rahm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Atopic dermatitis; laser treatment; nerves; neuropeptides; rosacea; sensitive skin; stinging;

    Sammanfattning : Rashes in dermatological disease are often accompanied by subjective symptoms, but in some cases the subjective symptoms are the most prominent signs of skin disorder. This is the case in "stinger patients", who may have an obvious skin disease, but in other cases there are no clear-cut reasons for the symptoms. LÄS MER
