  1. 1. Impact of pre-treatments on the brightness stability of a conventional and near neutral pH ECF-light bleaching sequence

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Ali Amirjani; [2023]
    Nyckelord :ECF; Bleaching; Pulp; AOX; Brightness Stability; ECF; Blekning; Massa; AOX; Ljushetsstabilitet;

    Sammanfattning : Syftet med denna studie är att undersöka inverkan av förbehandlingar på ljushetsstabiliteten av Northern Bleached Softwood Kraft (NBSK) som har blekts enligt (OO) (OP) D/Dn (PO) bleksekvensen. Effekten av förbehandling med xylanas (X), mild sur (A), DTPA (Q) samt ett kombinerad DTPA- & xylanassteg (Q+X) har studerats. LÄS MER

  3. 2. Resting-state Functional Connectivity in Anhedonia: Exploring the Effects of Pramipexole

    Master-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Frida Smids; [2023]
    Nyckelord :Anhedonia; Depression; Reward; Pramipexole; Resting-state; Functional Connectivity; Nucleus Accumbens; Social Sciences;

    Sammanfattning : Pramipexole is a medication that normalises dopamine signalling in the brain. Previous studies have suggested that pramipexole is an effective treatment option for depression and anhedonia because it targets the dopaminergic pathways within the brain’s reward network. LÄS MER

  4. 3. STUDENT-LED STRESS- AND SLEEP-INTERVENTIONS : Longitudinal changes in mental health symptoms for primary care patients

    Master-uppsats, Umeå universitet/Institutionen för psykologi

    Författare :Johanna Törnström; [2023]
    Nyckelord :;

    Sammanfattning : Mental health issues are a growing problem, and vast contributors are stress-related mental health issues and sleep problems. The health care system is struggling to adjust, and to calibrate the right interventions to the right patients at the right time. LÄS MER

  5. 4. Sustainable water treatment in the manufacturing industry : Investigation of the water treatment system at VCE, Hallsberg

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Johan Hagströmer; Forsberg Emma; [2023]
    Nyckelord :;

    Sammanfattning : Transitioning to circular flows is essential to economize the planet’s resources. One of the most important resources on earth is water as it is vital for all living things. However, water purification methods have proven to be very energy intensive, and increasing the circular water flows is therefore challenging. LÄS MER

  7. 5. Cultivating oleaginous yeast on spent mushroom substrate and logging residues hydrolysate : an assessment of yeast growth on side product substrates from the food, agriculture, and forestry industry

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Robin Lukic; [2023]
    Nyckelord :Lignocellulose; side products; oleaginous yeast; yeast oil; microtiter plate system; redox indicator; yeast growth; spent mushroom substrate hydrolysate; logging residues hydrolysate;

    Sammanfattning : There is an interest in finding alternatives to vegetable oils because of negative environmental impact. Many green sectors generate an abundant amount of side products that are inedible and consist in large of lignocellulose rich materials. LÄS MER
