  1. 1. Elevers svårigheter med bevisföring i geometri : En litteraturstudie om högstadie- och gymnasieelevers svårigheter inom bevisföring i geometri

    Uppsats för yrkesexamina på grundnivå, Linköpings universitet/Analys och didaktik; Linköpings universitet/Tekniska fakulteten

    Författare :Nils Strandler; Donna Mach; [2022]
    Nyckelord :Geometri; bevisföring; bevis; van Hiele; svårigheter;

    Sammanfattning : Elevers kunskaper inom bevisföring i geometri har länge presenterats som bristande, både nationellt och internationellt. Denna litteraturstudie syftar till att studera vilka svårigheter elever stöter på i arbetet med bevisföring inom geometri för att ge en samlad bild av vanliga missuppfattningar. LÄS MER

  3. 2. International genomic evaluation of Brown Swiss and Holstein dairy cattle : multi-trait vs. single-trait approach

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

    Författare :Sallam Mohammed Abdallah Ahmed; [2020]
    Nyckelord :Genotype-based international genomic evaluation; single trait; multi-trait; reliability; MACE proofs; national proofs; selection index; Brown Swiss; Holstein; Gene by environment interaction;

    Sammanfattning : International genomic evaluation for Brown Swiss population known as InterGenomics, was officially launched in 2011 by Interbull Center in Uppsala, Sweden. The routine evaluation is currently carried out using a single-trait approach where estimated breeding value from multi-trait across countries evaluation (MACE EBV) are used as a dependent variable and genetic corre-lations are assumed to be equal to one between countries.

  5. 4. International and national genetic evaluation of beef cattle : validation of national genetic evaluation models

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

    Författare :Jenny Ahlqvist; [2010]
    Nyckelord :beef; cattle; genetic; evaluation; international; models; Interbeef; charolais; limousin; data validation;

    Sammanfattning : After a workshop in Kuopio held in June 2006, Interbull decided to go forward with the development of a system for beef international genetic evaluation and a three year project called Interbeef was launched in June 2007. The participating countries are so far limited to Europe and the only trait evaluated at present is adjusted weaning weight (weight at 200 days). LÄS MER
