    Sammanfattning : Parastomal hernia (PSH) is a common complication to all ostomies, and all too well known to colorectal surgeons. Up to half of all stomates get a PSH. PSH may present itself as a protrusion or a bulge of the stoma that contains bowel or other content of the abdominal cavity. The symptom load varies from none to debilitating. LÄS MER

  4. 3. Navigating interconnected and electrified industries in the landscape of uncertainty : Exploring outcomes and values within circular solutions, and Swedish electricity supply and utilisation dynamics

    Författare :Christoffer Wadström; Maria Johansson; Erik Dahlquist; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular system; Outcomes and values in industrial symbiosis; Global economic policy uncertainty; Energy system; Electricity use dynamics;

    Sammanfattning : As the global community faces unprecedented climate change challenges, the transition towards a sustainable society has become an urgent priority. The complexity of this transition is characterised by the interplay of developing and implementing green manufacturing processes, integrated energy systems, and circular resource flows, and the inherent dynamics associated with geopolitical uncertainties, energy price fluctuations, and global instability.
