  1. 6. Badge It Up : The Effect of Gamification on Online Survey Response

    Kandidat-uppsats,

    Författare :Kim Siebeneicher; Edit Söderqvist; [2023]
    Nyckelord :Gamification; badges; online survey; motivation; volunteer; non-profit organisation; Gamification; medaljer; onlineenkät; motivation; volontär; ideell organisation;

    Sammanfattning : Collecting qualitative feedback from volunteers is essential but challenging for non-profit organisations. Gamification has been used in different contexts to try to improve users’ motivation, but has presented mixed results in the context of online surveys. LÄS MER

  3. 7. Relatedness and diversity in Swedish local chicken breeds using mitochondrial DNA D-loop sequences and SNP data

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Esther Taiwo Afolabi; [2023]
    Nyckelord :chicken; genetic diversity; mtDNA d-loop; SNP; Swedish local chicken breeds;

    Sammanfattning : Genetic diversity is the variation in genetic information carried by individuals within a species or population. This variability plays a crucial role in enabling species to adapt and survive in changing environments and is essential for evolutionary processes. LÄS MER

  4. 8. Wavelength-dependent limb darkeningin the analysis oftransit spectroscopy of exoplanets

    L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Alberto García Ribas; [2023]
    Nyckelord :;

    Sammanfattning : Limb darkening, an optical effect characteristic of stars, where the limb (edge) seemsto be darker than the centre of the stellar body; plays an important role in our under-standing of exoplanetary transits, as it is fundamental for developing light curve modelsthat can help to undercover extrasolar companions. To recover atmospheric featuresfrom exoplanets, a principal component analysis method is typically used. LÄS MER

  5. 9. Comparing processed and raw honey microbiota using 16S gene barcoding

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Ricardo Antonio Casu Pereira de Sousa; [2023]
    Nyckelord :;

    Sammanfattning : Still one of the most important animals on the planet, Honeybees are responsible for pollinating several species of plants that are vital to the ecosystem. They also produce honey, which is one of the few natural edible products of animal origin and has many beneficial properties for humans. LÄS MER

  7. 10. Detecting Chromatography Unit Degradation : Comparison of single- and multi-point techniques implemented in system control and monitoring software

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Max Markensten; [2023]
    Nyckelord :PCA; SOP-MPT; Fibro; chromatography; affinity A;

    Sammanfattning : Chromatography units, used in the production of pharmaceuticals, degrade with use and need to be changed or repackaged. This study investigates the effectiveness of two statistical methods, principal component analysis and simple and one-point multiparameter technique, for determining degradation in the Fibro chromatography unit.
