  1. 1. Vilken effekt har vassleprotein på benmineraldensitet? En systematisk litteraturöversikt bland vuxna ≥ 35 år.

    Kandidat-uppsats, Göteborgs universitet/Institutionen för medicin

    Författare :Felicia Andersson; Clara Johansson; [2024-02-09]
    Nyckelord :Whey protein; bone mineral density; adults; Vassleprotein; benmineraldensitet; vuxna;

    Sammanfattning : Syfte: Syftet med denna systematiska litteraturöversikt är att undersöka om supplementering av vassleprotein har någon påverkan på bentäthet (BMD) hos vuxna ≥35 år. Metod: Litteratursökningen gjordes i två databaser, Pubmed och Scopus. Sökord för blocken var vassleprotein, BMD och randomiserade kontrollerade studier (RCT). LÄS MER

  3. 2. Implementation of Dyson equation to accelerate convergence in RS-LMTO-ASA code

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Elis Uebel; Viktor Frilén; [2024]
    Nyckelord :Density functional theory; Dyson equation;

    Sammanfattning : First-principle calculations is a key ingredient for us to understand, improve and design new materials. Density functional theory (DFT) [1] has proven to be a very powerful tool and a number of different versions exist depending on the problem at hand. LÄS MER

  4. 3. Oscillations in a complex sunspot: From theory to data

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Femke Kranenbarg; [2024]
    Nyckelord :;

    Sammanfattning : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

  5. 4. Feasibility Study of Energy Harvesting via Biofuel Cell for Miniaturised Implantable Biosensors

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Rebecca Bonato; [2024]
    Nyckelord :Biofuel cell; Blood; Energy Harvesting; Glucose; Power Density; Oxygen;

    Sammanfattning : In the current pursuit of sustainable energy, biofuel cells are attracting considerable attention. Within biomedical engineering, the concept of harnessing energy from biological fluids, such as blood, holds significant promise, enabling both full autonomy and miniaturization. LÄS MER

  7. 5. The Impact of Global Warming on Wind Power Potential in the Greater Horn of Africa

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Bromwel Apondi; [2023-08-17]
    Nyckelord :Near-surface wind speed; the Greater Horn of Africa; ERA5; Wind power density; CORDEX-Africa;

    Sammanfattning : The wind speed variability and wind power potential in the Greater Horn of Africa is analyzed in this study to fill a knowledge gap regarding if wind power can be used more as a source of energy for the region. This is investigated based on reanalysis data from ERA5, observed wind speeds, CORDEX-Africa regional climate models (RCMs) for future projections and a literature review. LÄS MER
