    Sammanfattning : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. LÄS MER

  3. 2. The New Production of Politics : Between the No Longer and the Not Yet

    Författare :Elisabeth Gulbrandsen; Lena Trojer; Peter Ekdahl; Anna Kaijser; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Feminist technoscience; Responsible research and innovation; Grand challenges; Politics; Models of science and society; Figuration; Hermeneutics; Citizen scientist; Participant provocation; Situated futures;

    Sammanfattning : Indications that the global environmental and inequality crises are intimately linked to our western ways of living, challenge the self-understanding of participants in the modern research-complex. As researchers we not only observe, unveil, analyse and solve problems "out there". LÄS MER

  4. 3. Nitrous oxide and methane emissions from storage and land application of organic fertilisers : with the focus on sewage sludge

    Författare :Agnes Willén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Organic fertiliser handling contributes to greenhouse gas emissions. Through storage and field experiments, this thesis examined strategies to reduce emissions of nitrous oxide (N2O) and methane (CH4) from storage and after land application of cattle slurry (CS) and sewage sludge (SS).

  5. 4. Transforming technocultures : Feminist Technoscience, Critical Design Practices and Caring Imaginaries

    Författare :Linda Paxling; Lena Trojer; Peter Giger; Johanna Sefyrin; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feminist technoscience; critical design practices; innovation; care;

    Sammanfattning : The digital era has brought forward many innovative technologies but their contribution to resilient, inclusive and sustainable societies remain ambiguous. Innovation has often been considered a key component for production and economic growth, but this notion is gradually changing. LÄS MER

  7. 5. On the Military Utility of Spectral Design in Signature Management : a Systems Approach

    Författare :Kent Andersson; Jouko Vankka; Gunnar Hult; Hans Kariis; Hans Liwång; Harold Lawson; Jari Hartikainen; Försvarshögskolan; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; military utility; survivability; signature management; systems engineering; camouflage; Low Observable Technology; spectral design; multi-spectral; Försvarssystem; Military Technology;

    Sammanfattning : There is an ongoing duel between military sensor development and developments in signature management. The last decade, with warfare characterized by joint expeditionary operations and asymmetry, has favored sensors. LÄS MER
