    Författare :Hristina Bodin; Karin Tonderski; Jesper Persson; Stefan Weisner; Per Milberg; Hans Brix; Linköpings universitet; []
    Nyckelord :constructed wetland; free water surface flow; wastewater treatment; Kenya; Sweden; vegetation; harvest; Cyperus papyrus; Echinochloa pyramidalis; mass load; phosphorus; ammonium; suspended solids; pollutant removal; hydraulics; residence time distribution; data analysis methods; Konstgjorda våtmarker; avloppsvatten; vattenrening; fosfor; ammonium; partiklar; Kenya; Sverige; växter; Cyperus papyrus; Echinochloa pyramidalis; skörd; hydraulik; dataanalysmetod;

    Sammanfattning : Degradation of water resources has become one of the most pressing global concerns currently facing mankind. Constructed Wetlands (CWs) represent a concept to combat deterioration of water resources by acting as buffers between wastewater and receiving water bodies. LÄS MER

  3. 2. Outcomes and safety of new techniques for pulmonary vein isolation in patients with paroxysmal and persistent atrial fibrillation : A study based on randomised trials and registries

    Författare :David Mörtsell; Carina Blomström-Lundqvist; Stefan Lönnerholm; Isabel Deisenhofer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; antiarrhythmic drugs; ablation; cryoballoon; radiofrequency; pulmonary vein isolation; quality of life; arrhythmia monitoring; implantable cardiac monitor; atrial fibrillation burden; health economics; Cardiology; Kardiologi;

    Sammanfattning : Atrial fibrillation (AF) is a common disease with a high prevalence in the adult population. Treatment of AF encompasses antiarrhythmic drugs and catheter ablation to reduce symptoms. LÄS MER

  4. 3. Individual placement and support (IPS) i en socialpsykiatrisk kontext : en väg till arbete för personer med psykiskt funktionshinder?

    Författare :Ulla Nygren; Mikael Sandlund; Birgitta Bernspång; Urban Markström; Marie Åsberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arbetsrehabilitering; psykiatri; arbetsterapi; aktivitetsidentitet; förändringsprocesser;

    Sammanfattning : Introduktion Delaktighet i arbete är för de allra flesta människor en önskad och viktig aktivitet av många olika anledningar, men för personer med en psykisk sjukdom är inklusionen i arbetslivet begränsad. I Sverige är en psykiatrisk diagnos den vanligaste orsaken till sjukskrivning och värst är situationen för unga personer (2011). LÄS MER

  5. 4. Selected Aspects of Navigation and Path Planning in Unmanned Aircraft Systems

    Författare :Mariusz Wzorek; Andrzej Szałas; Jacek Malec; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Path planning; motion planning; autonomous Unmanned Aircraft Systems UAS ; Hierarchical Concurrent State Machines HCSM ; UAV;

    Sammanfattning : Unmanned aircraft systems (UASs) are an important future technology with early generations already being used in many areas of application encompassing both military and civilian domains. This thesis proposes a number of integration techniques for combining control-based navigation with more abstract path planning functionality for UASs. LÄS MER

  7. 5. Development of Novel Hydroporphyrins for Light Harvesting and Sensitising NIR Lanthanide Luminescence

    Författare :Ruisheng Xiong; Eszter Borbas; Christian Brückner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chlorin; hydroporphyrin; chlorophyll analogues; light harvesting; lanthanide luminescence; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Sammanfattning : Chlorins, as the core structures of chlorophylls, have been extensively studied for harvesting solar energy, fluorescent imaging and photodynamic therapy against cancer. This thesis is concerned with design and synthesis of novel chlorins as antennae for harvesting light and sensitising near infrared lanthanide luminescence. LÄS MER
