  1. 1. Optical Communication using Nanowires and Molecular Memory Systems

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Thomas Kjellberg Jensen; [2024]
    Nyckelord :neuromorphic computing; nanowire; molecular dye; DASA photoswitch; OBIC; Physics and Astronomy;

    Sammanfattning : Neuromorphic computational networks, inspired by biological neural networks, provide a possible way of lowering computational energy cost, while at the same time allowing for much more sophisticated devices capable of real-time inferences and learning. Since simulating artificial neural networks on conventional computers is particularly inefficient, the development of neuromorphic devices is strongly motivated as the reliance on AI-models increases.

  3. 2. Meadowscape : Bring health to ecological systems through actions in the agricultural landscape

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Arkitekthögskolan vid Umeå universitet

    Författare :Anna Östlund; [2023]
    Nyckelord :Actor-network theory; landscape ecology; agriculture; artifacts; patterns;

    Sammanfattning : The physical landscape is a patchwork of different physical and immaterial structures and networks built up through time, where nature and culture cooperate in processes of shaping the landscape. Since the first settlers in Sweden the grass meadow has taken a central part in the agricultural practices, but today little of this landscape remains. LÄS MER

  4. 3. Chromatin accessibility analysis of spaceflight mouse brains using ArchR

    Master-uppsats, KTH/Genteknologi

    Författare :Raphaël Mauron; [2023]
    Nyckelord :Single nuclei ATAC-sequencing; Space Biology; DNA Chromatin accessibility; Neurodegenerative; ArchR; ATAC-sekvensering av enskilda kärnor; rymdbiologi; tillgänglighet av DNA kromatin ; neurodegenerativa sjukdomar; ArchR;

    Sammanfattning : Mänsklig utforskning av månen och Mars innebär stora utmaningar för människans fysiologi och hälsa på grund av de unika miljöfaktorer som följer av långvariga rymduppdrag. Rymdbiologiska experiment har blivit ett viktigt verktyg för att studera effekterna som mikrogravitation och rymdstrålning har på levande organismer, i syfte att förstå och minska dessa utmaningar.

  5. 4. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Hana Faulds; [2023]
    Nyckelord :Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

  7. 5. När ingen vuxen är självklar : En undersökning av självbiografier om att vara familjehemsplacerad

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Margareeta Jakimainen; Sahar Tallouzi; [2023]
    Nyckelord :Attitudes; behaviours; emotions; foster care; foster children; personal treatment.;

    Sammanfattning : The purpose of this study is to analyze experiences of moving to and living in a foster home. The empirical material consists of autobiographies written by children placed in family homes when they have become adults. This study analyzes how the emotional and behavioral aspects of the experiences are portrayed in the autobiographies. LÄS MER
