  1. 16. Superdiffusive Spin Transport and Ultrafast Magnetization Dynamics : Femtosecond spin transport as the route to ultrafast spintronics

    Författare :Marco Battiato; Olle Eriksson; Hardy Gross; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ultrafast magnetisation dynamics; anomalous diffusion; femtosecond dynamics; magnetism; Materialvetenskap; Materials Science;

    Sammanfattning : The debate over the origin of the ultrafast demagnetization has been intensively active for the past 16 years. Several microscopic mechanisms have been proposed but none has managed so far to provide direct and incontrovertible evidences of their validity. LÄS MER

  3. 17. Mobbning, intriger, offerskap : att tala om sig själv som mobbad i arbetslivet

    Författare :Helena Blomberg; Mats Börjesson; Rolf Lidskog; Katarina Jacobsson; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; narrative analysis; discursive psychology; metaphor analysis; interpretative repertoire; rhetorical resources; victimization; workplace bullying; identity work; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Sociology; Sociologi; Sociologi; Sociology;

    Sammanfattning : This thesis is a study of bullying narratives, mainly co-produced in a process of ongoing interaction. The focus is on how narrators rhetorically organize their storytelling and identity work by using discursive resources. LÄS MER

  4. 18. Pollination in Ephedra (Gnetales)

    Författare :Kristina Bolinder; Catarina Rydin; Jürg Schönenberger; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; växtsystematik; Plant Systematics;

    Sammanfattning : Pollination, i.e., the transport of male gametophytes to female gametophytes, can occur with biotic or abiotic vectors and is necessary for fertilization and completion of the lifecycle in all seed plants. LÄS MER

  5. 19. The Quest for M-theory

    Författare :Ulf Gran; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; solitons; gauge symmetry; M-theory; string theory; duality; p-branes; D-branes; superspace; supergravity;

    Sammanfattning : In ten dimensions, there exist five consistent string theories and in eleven dimensions there is a unique supergravity theory. When trying to find the fundamental theory of nature this is clearly an "embarrassment of riches". In the mid 90s, however, it was discovered that these theories are all related via a kind of transformation called duality. LÄS MER

  7. 20. Exploring Designs for a Process Prioritisation Method

    Författare :Jens Ohlsson; Shengnan Han; Paul Johannesson; Jan vom Brocke; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Process prioritisation; exploration; process innovation; design science research; business process management; disruptive technology; capability layer model; systems thinking; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Problem/Purpose: Process prioritisation is an ill-structured and complex problem that remains a mystery phase in business process management (BPM) research. More explorative approaches are called upon to tackle process management problems, to facilitate process innovation and to design new processes in dynamic environments. LÄS MER
