  1. 16. Vascular targeting for enhanced cancer immunotherapy

    Författare :Maria Georganaki; Anna Dimberg; Sara Mangsbo; Lena Claesson-Welsh; Wolf Hervé Fridman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer immunotherapy; tumor vasculature; endothelial activation; IDO1; ELTD1; tertiary lymphoid organ; Biologi; Biology;

    Sammanfattning : Induced angiogenesis and chronic inflammation are major components of tumor immunosuppression. The scope of this thesis is to understand the role of the vasculature in anti-tumor immunity and thereby to improve cancer immunotherapy. LÄS MER

  3. 17. Denitrification in a Non-nitrifying Activated Sludge System Employing Recirculation from a Tertiary Nitrification Unit

    Författare :Ann Mattsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nitrogen removal; denitrification; activated sludge; post nitrification; pilot plant;

    Sammanfattning : A non-nitrifying, denitrifying activated sludge system has been demonstrated to give high denitrification rates and to be a useful component in a municipal wastewater treatment plant where partial nitrogen removal is required. One useful configuration is where clarified effluent from a non-nitrifying activated sludge system is nitrified in a tertiary nitrification unit and recirculated to the activated sludge system for denitrification.

  4. 18. Recycling of wastewater nutrients in a wetland filter

    Författare :Karin Sundblad-Tonderski; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : This thesis demonstrates the possibility of using wastewater nutrients for plant biomass production and concomitantly achieving year-round wastewater treatment. As part of a joint research project, the emphasis in this thesis is on nutrient recycling capacity relative to treatment efficiency. LÄS MER

  5. 19. Application of chemical oxidation processes for the removal of pharmaceuticals in biologically treated wastewater

    Författare :Gerly Hey; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The discharge of effluents from wastewater treatment plants (WWTPs) is considered to be the major source of residual pharmaceuticals frequently found in aquatic environments. The complex nature of such compounds tends to make conventional biological treatments aimed at their removal ineffective. LÄS MER

  7. 20. Optimizing processes for biological nitrogen removal in Nakivubo wetland, Uganda

    Författare :Joseph Kyambadde; Gunnel Dalhammar; Karin Tonderski-Sundblad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Ammonium-oxidizing bacteria; Biological nitrogen removal; Coliform retention; Constructed wetlands; Cyperus papyrus; Miljöteknik; Environmental engineering; Miljöteknik;

    Sammanfattning : The ability of Nakivubo wetland (which has performed tertiary water treatment for Kampala city for the past 40 years) to respond to pollution and to protect the water quality of Inner Murchison Bay of Lake Victoria was investigated. The aim of this study was to assess the capacity of Nakivubo wetland to remove nitrogen from the wastewater after its recent encroachment and modification, in order to optimize biological nitrogen removal processes using constructed wetland technology.
