  1. 1. Stress in chickens : Effects of domestication and early experience on behaviour and welfare

    Författare :Maria Ericsson; Per Jensen; Linda Keeling; Bjarne Braastad; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The domestication is the process where animals have adapted to human conditions. A prerequisite for domestication is tame behaviour towards humans and subsequently, selection for other desirable traits took place which led to changes in several behavioural and physiological parameters.

  3. 2. Stress response regulation and protein aggregate inheritance in Caulobacter crescentus

    Författare :Frederic Dominique Schramm; Kristina Jonas; Franz Narberhaus; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stress; protein aggregation; cellular aging; molecular chaperones; heat shock response; DnaK; sigma factor; suppressor genes; DNA replication; starvation; Caulobacter crescentus; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Many stress conditions a cell encounters threaten the continuation of basic biological processes ultimately endangering its survival. Heat shock and antibiotic exposure can lead to a sudden surge of protein un- and misfolding, while nutrient starvation directly causes a lack of energy and molecular building blocks. LÄS MER

  4. 3. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies

    Författare :Prabhat Pant; Ru Peng; Johan Moverare; Kjell Simonsson; Thomas Niendorf; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM; Scan strategies; Build orientations;

    Sammanfattning : Components with complex features that are designed with their function as a core aspect often are not viable to be manufactured with traditional methods. This has been a bottleneck in the past, leading to heavier parts with various sub-assemblies and a significant waste of material. LÄS MER

  5. 4. RsbX and stress response in Listeria monocytogenes

    Författare :Ana Henriques de Oliveira; Jörgen Johansson; Cormac Gahan; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Listeria monocytogenes; SigB; stressosome; RsbX; phosphorylation; growth; competitiveness; motility; energetic cost; homeostasis; stress response; virulence; invasion; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Sammanfattning : Listeria monocytogenes is a ubiquitous foodborne Gram-positive bacterium. Despite being mainly a soil bacterium, it can reach the food processing environment and contaminate food destined for human consumption, causing outbreaks. LÄS MER

  7. 5. Stress Related Emissions of Norway Spruce Plants

    Författare :Marie Pettersson; Anna-Karin Borg-Karlson; Torkel Berglund; Åsa Emmer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; volatiles; terpenes; green leaf volatiles; stress response; nepetalactone; SPME; Picea abies; Hylobius abietis; Cinara pillicornis; Chemistry; Kemi;

    Sammanfattning : The interactions between plants and insects are mediated by volatile molecules. Plants respond to stress by biosynthesis of chemical substances which can deter invading insects or pathogens. Some of these substances are volatile and are emitted to the surroundings and may attract or repel insects. LÄS MER
