  1. 1. Size-dependent predator-prey interactions, distribution and mortality in salmon: effects on individuals and populations

    Författare :Philip Jacobson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The biomass dynamics of populations is largely determined by the survival, growth, and reproduction of individuals. For fish and other animals, survival, growth, and reproduction depends on the amount of energy an individual obtains via feeding and are therefore food-dependent. LÄS MER

  3. 2. New insights into lubricated tribological contacts

    Författare :Elin Larsson; Staffan Jacobson; Åsa Kassman Rudolphi; Jannica Heinrichs; Philip Shipway; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; friction; wear; lubrication; fuel additive; boric acid; tribofilm; transport; fuel efficiency; surface analysis; grease; LiX grease; PP grease; fretting; electrical contacts; cross section; copper; silver; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : The emissions of carbon dioxide, CO2, must rapidly be reduced to avoid severe climate change. Tribology-related solutions can be an important part in reducing these emissions. The aim of this thesis is to improve the fundamental knowledge in two tribology-related fields, both concerning lubrication, to enable such solutions in the future. LÄS MER
