  1. 1. Divisive structures : Two billions years of biofilament evolution

    Författare :Fredrik Hurtig; Ann-Christin Lindås; Lionel Guy; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Evolution; Archaea; Eukaryogenesis; ESCRT-III; Actin; Profilin; Gelsolin; Asgard; TACK; Sulfolobus; Cell division; Cytokinesis; Cytoskeleton; Heimdallarchaeota; Actin-binding protein; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Our understanding of the functional and regulatory complexity that existed in the eukaryotic progenitor is poor, and investigations have been hindered by our nebulous understanding of where eukaryotes stem from. Recently discovered archaeal lineages with hitherto unseen homology to eukaryotic systems suggest archaea can further our understanding of the eukaryotic cell’s ancestry. LÄS MER

  3. 2. Mathematics teaching through the lens of planning : actors, structures, and power

    Författare :Helena Grundén; Jeppe Skott; Sara Irisdotter Aldenmyr; Anna Chronaki; Linnéuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; mathematics teaching; planning; Critical Discourse Analysis; actors; structures; power; Mathematical Education; Matematikdidaktik;

    Sammanfattning : This dissertation explores mathematics teaching by focusing on planning. The planning is seen as a social phenomenon related to surrounding practices and power relations in and between practices. Hence, planning in this dissertation is explored beyond what teachers do when planning. LÄS MER

  5. 4. Supporting knowledge management with information technology : the significance of formal and informal structures

    Författare :Karin Dessne; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; knowledge management; km; cscw; cscl; communities of practice; cop; military; lessons learned; experience; learning; knowing; formal; informal; structures; knowing wheel; preconditions; it support; collaborative work; communication; Datalogi; Computer and Systems Science; Teknik; Technology;

    Sammanfattning : Knowledge Management (KM) is a relatively young field of research. It has traditionally aimed at managing work in organisations often by the assistance of supporting Information Technology (IT).In this thesis, the definition of KM is expressed as facilitating the intertwined process of learning and knowing in an organisation.

  7. 5. Structures and processes in the Mercury magnetosphere

    Författare :Elisabet Liljeblad; Tomas Karlsson; Anita Kullen; Haje Korth; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mercury; MESSENGER; magnetosphere; processes; structures; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The mechanisms involved in the transfer of mass and energy from the solar wind to any planetary magnetosphere is considered an important topic in space physics. With the use of the Mercury spacecraft MESSENGER's data, it has been possible to study these processes in an environment different, yet similar, to Earth's. LÄS MER
