  1. 1. Characterization of a site-specific gene-transfer mechanism in bacteria

    Författare :Karin Hansson; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Pharmaceutical Microbiology; farmaceutisk mikrobiologi;

    Sammanfattning : Integrons capture and rearrange single genes borne on mobile units called cassettes using site-specific recombination. The integrons increase the variation of antibiotic resistance among bacterial plasmids and may also reorganize clustered genes in bacterial genomes. LÄS MER

  2. 2. On the hot crack formation during solidification of iron-base alloys

    Författare :Karin Hansson; KTH; []
    Nyckelord :hot cracking; hot tearing; cracking fracturing ; tearing; ductility; brittleness; embrittlement; fractures; ductile brittle transition; solidification; iron; copper; nickel; Invar; steels; free machining steels; stainless steels; penetration; crack;

    Sammanfattning : Hot cracking during solidification is a severe problem inmany casting processes, for example in continuous casting.Combinations of low strength and low ductility of the materialat high temperatures and applied tensile stress can cause hotcracking. LÄS MER

  3. 3. Preclinical investigation of novel therapies against neuroblastoma

    Författare :Karin Hansson; Avdelningen för translationell cancerforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; Neuroblastoma; Translational research; Preclinical drug evaluation;

    Sammanfattning : Neuroblastoma is a childhood tumor of the sympathetic nervous system and the most common tumor form diagnosed in infants. Patients with aggressive tumors are treated intensely with multi-modal therapy including chemotherapy, surgery, radiotherapy and immunotherapy. LÄS MER

  4. 4. A Framework for Evaluation of Flood Management Strategies

    Författare :Karin Hansson; Love Ekenberg; Mats Danielson; Anna Vári; Stockholms universitet; []
    Nyckelord :flood; decision; multi criteria; simulation; evaluation; data- och systemvetenskap; Computer and Systems Sciences;

    Sammanfattning : During the last decades, a great deal of attention has been focused on the financial risk management of natural disasters. The reason is that the economic losses from floods, windstorms, earthquakes and other disasters in both the developing and developed countries are escalating dramatically. LÄS MER

  5. 5. Accommodating differences : Power, belonging, and representation online

    Författare :Karin Hansson; Love Ekenberg; Ina Wagner; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; e-participation; e-democracy; online identity; artistic research; visual method; participatory method; belonging; singularity; performative states; data- och systemvetenskap; Computer and Systems Sciences;

    Sammanfattning : How can political participatory processes online be understood in the dynamic, conflicted and highly mediated situations of contemporary society? What does democracy mean in a scenario where inequality and difference are the norms, and where people tend to abandon situations in which they and their interests are not recognized? How can we accommodate differences rather than consensus in a scenario where multiple networks of people are the starting point rather than a single community?In this thesis, these questions are explored through an iterative process in two studies that have used or resulted in three prototypes and one art exhibition. The first study is of communication practices in a global interest community, which resulted in two prototypes: Actory, a groupware that takes differences rather than equality as the starting point for a collaborative tool, and The Affect Machine, a social network where differences are used as a relational capital.
