  2. 1. Electron-scale physics in space plasma : Thin boundaries and magnetic reconnection

    Author : Cecilia Norgren; Mats André; Jonathan Eastwood; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Most of the observable Universe consists of plasma, a kind of ionized gas that interacts with electric and magnetic fields. Large volumes of space are filled with relatively uniform plasmas that convect with the magnetic field. READ MORE

  4. 2. The impact of macronutritional composition and ketosis on cognitive health : from normal aging to Alzheimer’s disease

    Author : Jakob Norgren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Ketogenic diets (KD) are increasingly investigated for the prevention of cognitive decline and Alzheimer’s disease (AD). Without explicitly investigating a KD, this thesis disentangles two of its hallmarks: a reduced dietary carbohydrate/fat-ratio (CFr) and the metabolic state ketosis. READ MORE

  7. 5. Valorization of Low Value Organic Waste by the use of Black Soldier Fly Larvae – Bioconversion of Sludge from the Pulp and Paper Industry

    Author : Robert Norgren; Anders Jonsson; Olof Björkqvist; William Hogland; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sustainable sludge management; bioconversion; insect protein;

    Abstract : The current economic system is not sustainable, as it is based on a linear flow of resources from extraction, production, use and disposal. The linear flow of resources must be replaced with a circular flow where waste is seen as a resource. READ MORE
