  1. 1. 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

  3. 2. Potential of waste-derived VFAs-bearing effluents as an external carbon source for MBBR denitrification of domestic wastewater

    Magister-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Seyed Reza Manafi Khosroshahi; [2022]
    Nyckelord :Volatile fatty acids; Denitrification; Wastewater treatment; Biological nutrient removal; Nitrate removal; Electron accepter; Carbon source; Electron doner; Moving bed biofilm reactor; Nanofiltration; VFA concentration; Discharge standards; Carriers; acclimatization; VFAs; MMBR; NF; WWTP; BNR;

    Sammanfattning : In conventional wastewater treatment plants, methanol, ethanol, and acetate are used as carbon source for the denitrification process in the biological nutrient removal. However, growing concern regarding economical costs and carbon footprints from the fossil-based production of these chemicals have forced the companies to look for other alternatives. LÄS MER

  4. 3. Spatial resolution threshold in layers and red jungle fowls : are there differences due to light intensity or light spectra?

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Pauline Annerstedt; [2018]
    Nyckelord :spatial resolution threshold; layer; red jungle fowls; visual acuity;

    Sammanfattning : The domestic fowl (Gallus gallus domesticus) originates from the forests in South-east Asia. It may be correct to assume that the visual system of the domestic fowl is still adapted to light that is filtered through the green forest canopy. LÄS MER

  7. 5. Characterization of the metabolic changes in chicken liver due to exposure of perfluorooctane sulfonate (PFOS) during the embryo development

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Ayan Au Musse; [2017]
    Nyckelord :PFCs; PFOS; Lipidomics; Lipid metabolism; UHPLC Q-TOF-MS;

    Sammanfattning : Perfluoroalkyl substances (PFASs) are anthropogenic compounds that have been classed as persistent organic pollutants (POPs) and are found in both commercial and industrial products. PFASs have been detected in different environmental matrices and have been found to bioaccumulate in all trophic levels. LÄS MER
