  1. 1. Dog behaviour : Intricate picture of genetics, epigenetics, and human-dog relations

    Författare :Ann-Sofie Sundman; Lina Roth; Per Jensen; Zsófia Virányi; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Dogs, Canis familiaris, share the lives of humans all over the world. That dogs, and the behavior of dogs, are of interest to many is therefore no surprise. In this thesis, the main aim has been to identify factors that affect dogs’ behaviours.The dog, Canis familiaris, is our first domesticated animal. LÄS MER

  3. 2. Characterisation of social behaviour in red junglefowl and White leghorn laying hens : phenotypic and genetic studies

    Författare :Johanna Väisänen; Harry Blokhuis; Linköpings universitet; []
    Nyckelord :Red junglefowl; social behaviour; behaviour tests; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The objective of this thesis was, by using two model strains of chicken, red junglefowl and White Leghorn layer, to study differences in social behaviour of the species that could be derived from domestication and production related selection processes. The social phenotype characterisation was done to be able to further study the association of the social differences to specific production related traits as well as to certain genome areas in intercross and backcross lines generated from these two parental populations.

    Sammanfattning : Selective serotonin re-uptake inhibitors (SSRIs) are a class of anxiolytic and anti-depressant drugs. SSRIs act on the evolutionarily ancient serotonergic system which is virtually identical throughout the vertebrate phylum. LÄS MER

  5. 4. Mechanical anchorage of prestressed CFRP tendons : theory and tests

    Författare :Anders Bennitz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Fibre Reinforced Polymers (FRPs) are slowly becoming important materials to consider also for a structural engineer. They are light-weight, insensitive to corrosion and have highly modifiable mechanical properties. LÄS MER

  7. 5. Sustainability and Flexural Behaviour of Textile Reinforced Concrete

    Författare :Natalie Williams Portal; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment LCA ; sustainability; Textile Reinforced Concrete; TRC; facade elements; flexural behaviour; non-linear finite element analyses; structural tests;

    Sammanfattning : Concrete reinforced with conventional steel is one of the most commonly used building materials, yet it has historically shown disadvantages in terms of durability and vulnerability to corrosion attack. Various remedial methods have been applied to overcome the shortcomings of this building material, such as increasing the concrete cover, which, however, leads to an increased self-weight of the structure.
