    Sammanfattning : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable sanitation; sand filter; phosphorus filter; package plant; cold climate; treatment process; system analysis; sustainability indicators; decentralization; centralization; historical development; on-site; resource recovery; source separation; source-separating systems; blackwater; urine; greywater; hållbarthetsanalys; små avlopp system; enskilda avlopp; markbädd; minireningsverk; kallt klimat; systemanalys; fosforfälla; fosforfilter; indikator; urin sortering; svartvatten; toalettvatten; gråvatten; BDT; VA-teknik; Urban Water Engineering;

    Sammanfattning : Current socio-technical wastewater system paradigms are being challenged by emerging global issues such as climate change, environmental degradation and scarcity of resources. Thus, exploration of innovative new urban water management solutions is required that enable closure of resource loops. LÄS MER

  4. 18. Novel methods for diagnosis and treatment of periodontal disease

    Författare :Anna Svärd; Torbjörn Bengtsson; Tülay Lindberg; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Periodontitis; inflammation; Porphyromonas gingivalis; gingipains; biosensing; gold nanoparticles; antimicrobial treatment; NC8;

    Sammanfattning : Periodontitis is an inflammatory condition affecting tooth-supportive structures, the periodontium. Gingival tissues respond to biofilm formation by initiating an inflammatory process. LÄS MER

  5. 19. Improving maintenance treatment of heroin addiction : the role of buprenorphine

    Författare :Karl Johan Kakko; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Heroin addiction is a condition with high morbidity and mortality. The discovery of Methadone Maintenance Treatment (MMT) by Dole and co-workers 1964 represented the first major advance in the treatment of this condition. Through the work of Gunne et al in Uppsala, MMT was implemented in Sweden already in 1966. LÄS MER

  7. 20. A Journey towards Sustainable Small Wastewater Treatment Systems in Low and Lower–Middle Income Countries

    Författare :Claudia Cossio Grageda; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater treatment system; local stakeholders; operation and maintenance; sustainability assessment; institutional dimension; EVAS tool EVAluation of Sustainability ; low and lower-middle income countries; sustainability indicators; resource recovery; performance assessment;

    Sammanfattning : The sustainability of small wastewater treatment systems (WWTSs) in low and lower-middle income countries represents a challenge in terms of functionality and optimal performance in the ongoing effort to treat wastewater sufficiently to enable safe discharge or reuse. The reuse of wastewater is a common practice in these countries, especially where water resources are scarce. LÄS MER
