  1. 21. Domestication and early experiences in chickens : Behavior, stress and gene expression

    Författare :Pia Katrine Løtvedt; Per Jensen; Jordi Altimiras; Emma Brunberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A number of animal species have undergone domestication, the process of becoming adapted to living in captivity and in proximity to humans. Common for these species is that they have all developed certain traits, including changes to coat color, body size and level of fearfulness. This has been termed the domestic phenotype. LÄS MER

  3. 22. Sensory evaluation and consumer preference of wine and food combinations : influences of tasting techniques

    Författare :Ingemar Tobias Nygren; Inga-Britt Gustafsson; Lisbeth Johansson; Åsa Öström; Hely Tuorila; Örebro universitet; []
    Nyckelord :Descriptive sensory analysis; tasting technique; sequential tasting; mixed tasting; wine; combination; Hollandaise sauce; blue mold cheese; consumers; preference; måltidskunskap; Culinary Arts and Meal Science; Måltidskunskap; Måltidskunskap; Culinary Arts and Meal Science;

    Sammanfattning : The entire project consists of five studies. Descriptive sensory analyses were performed on combinations of five dry white wines and either Hollandaise sauce with two levels of fat or two blue mould cheeses. Assessments were carried out by a student panel and by a selected and trained panel. LÄS MER

  4. 23. High Temperature Wear Processes

    Författare :Sinuhe Hernandez; Bojan Podgornik; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Moving machine assemblies are increasingly exposed to extreme operating conditions involving high temperatures owing to demands on higher power densities, high performance/efficiency and extreme environments. The changes in surface and near surface properties of contacting surfaces caused by exposure to high temperature and deformation govern the occurrence of friction, wear and material transfer of the tribological system.

  5. 24. Conserving the American Dream : Faith and Politics in the U.S. Heartland

    Författare :Erik Nilsson; Gudrun Dahl; Matthew Engelke; Stockholms universitet; []

  7. 25. Human-structure interaction effect on the dynamic response of footbridges : An analytical and experimental study

    Författare :Daniel Colmenares; Raid Karoumi; Andreas Andersson; Federica Tubino; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; footbridges; dynamics; human induced loads; human structure interaction.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : Lightweight, slender and lightly damped footbridges are often susceptible to HumanInduced Loads (HILs) when pedestrian step frequencies coincide with the naturalfrequencies of the structure. For vertical vibrations, this can compromise the serviceabilitylimit state of the system. LÄS MER
