2. 1. Digital play in preschools : understandings from educational use and professional learning

   Author : Leif Marklund; Elza Dunkels; Kenneth Ekström; Åsa Bartholdsson; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital play; preschool; digitalisation; tablets; professional learning; professional development; early years; digital competence; literacy; workplace learning; preschool teachers; early childhood education; technology integration; pedagogiskt arbete; educational work;

   Abstract : The purpose of this thesis is to improve knowledge on preschool teachers’ educational use of digital play and their professional learning about it. The thesis is focused on three questions; How can preschool teacher educational use of digital play be understood? How can the professional learning context of preschool teachers using digital play for educational purposes be understood? And, How can preschool teacher knowledge needs concerning educational use of digital play be understood?  The participants were preschool teachers who had started to introduce tablets and digital play in educational practice.

4. 2. Genetic Analysis of Fat Metabolism in Domestic Pigs and their Wild Ancestor

   Author : Frida Berg; Leif Andersson; Maria Moller; Stefan Marklund; Sigbjörn Lien; Uppsala universitet; []
   Keywords : Genetics; Pig; Quantitative Trait Locus; Fat deposition; FAT1; Linkage map; RH map; Comparative map; Backcross; Identical by Descent mapping; Brown adipose tissue; UCP1; Genetik;

   Abstract : The domestication of the pig began about 9 000 years ago and many of the existing domestic breeds have been selected for phenotypic traits like lean meat and fast growth. Domestic pigs are phenotypically very different from the ancestral wild boar that has adapted to survive in their natural environment. READ MORE

5. 3. QTL Analysis in the Pig : From the Identification of Quantitative Trait Loci to the Understanding of Molecular Mechanisms

   Author : Ellen Markljung; Leif Andersson; Göran Andersson; Göran Hjälm; Stefan Marklund; Holger Luthman; Uppsala universitet; []
   Keywords : ;

   Abstract : Domestic pigs have become very different form the wild ancestors they originate from. Selection for muscle growth and meat quality has made the pig a good model for genetic studies of muscle development.The first part of this thesis presents a genome-wide scan for quantitative trait loci (QTL) in a cross between Landrace and Hampshire pigs.

6. 4. Genetic Analysis of Quantitative Traits Using Domestic Animals : A Candidate Gene and Genome Scanning Approach

   Author : Hee-Bok Park; Leif Andersson; Stefan Marklund; Robert Fredricksson; Holger Luthman; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Domestication; horse; pig; chicken; quantitative traits; candidate gene; genome scan; PRKAG3; MC4R; selection experiment; growth; correlated response; metabolic disorders; Quantitative Trait Loci; linkage; single nucleotide polymorphisms; Genetik; Clinical genetics; Klinisk genetik;

   Abstract : Domestication has led to genetic changes that affect quantitative traits in farm animals. Both candidate gene analysis using association tests and genome scans based on linkage analysis have been performed to understand the molecular basis underlying quantitative genetic variation in horses, pigs and chickens.

7. 5. Mycobacterium avium infections in children

   Author : Johanna Thegerström; Björn Olsen; Britt-Inger Marklund; Jan Ernerudh; Leif Kirsebom; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Mycobacterium avium belongs to a group of over 130 species of non-tuberculous mycobacteria (NTM) or environmental mycobacteria. The subspecies Mycobacterium avium avium was originally described as the causative agent of bird tuberculosis, but was later found to cause disease also in humans. READ MORE
