    Sammanfattning : We have found that a set of group A streptococcal strains, primarily associated with skin infections, express surface-associated M proteins that bind plasminogen and plasmin with high affinity. The binding is mediated by a common 13 amino acid internal repeated sequence located in the NH2-terminal surface-exposed portion of these M proteins. LÄS MER

  5. 4. Automation in forestry : development of unmanned forwarders

    Författare :Ola Ringdahl; Thomas Hellström; Tomas Nordfjell; Arto Visala; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Computer science; Datavetenskap; Forest engineering; Skogsteknik; computer and systems sciences; data- och systemvetenskap;

    Sammanfattning : For the last 50 year, forestry operations have become more and more mechanized. In modern forestry in Europe two machines are typically used; a harvester that fells, debranches and cross-cuts the trees into logs and a forwarder that transports them to the nearest road. LÄS MER

  7. 5. Techniques and Algorithms for Autonomous Vehicles in Forest Environment

    Författare :Ola Ringdahl; Thomas Hellström; Jürgen Burstler; Hans Gripentrog; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Autonomous navigation; Robotics; Obstacle avoidance; Computer science; Datavetenskap;

    Sammanfattning : This thesis describes an ongoing project of which the purpose is designing and developing techniques and algorithms for autonomous off-road vehicles. The focus is on some of the components necessary to accomplish autonomous navigation, which involves sensing and moving safely along a user-defined path in a dynamic forest environment. LÄS MER
