  1. 36. Parentage Assignment using genetic markers in the common carp (Cyprinus carpio)

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Sven Kristian Feddersen; [2023]
    Keywords : single nucleotide polymorphism; Parentage Assignment; aquaculture; genetic markers;

    Abstract : This study investigated the effect of varying single nucleotide polymorphisms (SNPs) marker density, error threshold selection, and different SNP selection strategies on parentage assignment accuracy in carp populations. Using a marker set of 15,615 SNPs, we found a positive correlation between the quantity of SNP markers and the accuracy of parentage assignments, consistent with existing literature. READ MORE

  3. 37. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging

    University essay from KTH/Kemi

    Author : Arezu Sehati; [2023]
    Keywords : Coherent Diffraction Imaging; X-ray Free Electron Lasers; Refractive index; Core-shell nanoclusters; Rare-gas ionization; Koherent Diffraktionsavbildning; Röntgenfrielektronlaser; Brytningsindex; Core-shell-nanokluster; Ädelgasjonisering;

    Abstract : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. READ MORE

  4. 38. Genetisk variation hos lantrashöns : skillnader inom svenska lantraser och europeiska lantraser

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Andrea Hilding; [2023]
    Keywords : genetisk variation; lantras; höns; svensk lantras; Europa;

    Abstract : Detta arbete undersöker hur den genetiska variationen ser ut hos lantrashöns i Sverige och några europeiska länder. Den genetiska variationen är ett mått på vilken nivå av biologisk mångfald som finns inom en art eller population och kan visa på hur inavel tidigare förekommit i populationerna som undersöks.

  5. 39. Enhancing Accountability to Affected Populations through Donor Requirements : A grounded theory-based analysis of the current situation, donor motivations and bottlenecks around setting requirements, further constraints and how they could be overcome.

    University essay from Uppsala universitet/Teologiska institutionen

    Author : Clara Rattmann; [2023]
    Keywords : AAP; accountability to affected populations; humanitarian; accountability; participation; project design; proposal; funding; grant; donor requirement; disaster response; affected populations; donor; NGO; grounded theory;

    Abstract : Even though supporting affected populations is the raison d’etre for humanitarian action, organisations are frequently not accountable to populations they aim to serve. Despite several reform movements, the consultation and participation elements of accountability to affected populations (AAP), in particular, are still lacking. READ MORE

  6. 40. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Joel Fransson Forsberg; [2023]
    Keywords : Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

    Abstract : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. READ MORE
