  1. 21. Evaluation of microbial health risks associated with the reuse of source-separated humna urine

    Författare :Caroline Höglund; KTH; []
    Nyckelord :urine-separation; urine; wastewater systems; wastewater reuse; recycling; enteric pathogens; faecal sterols; indicator bacteria; hygiene risks; microbial persistence; microbial risk assessment; QMRA; fertiliser; crop;

    Sammanfattning : Human excreta contain plant nutrients and have the potentialto be used as a fertiliser in agriculture. Urine contributesthe major proportion of the nutrients (N, P and K) in domesticwastewater whereas faeces contribute a smaller amount andinvolves greater health risks if reused due to the possiblepresence of enteric pathogens.

  5. 24. Controlling Charge and Energy Transfer Processes in Artificial Photosynthesis : From Picosecond to Millisecond Dynamics

    Författare :Magnus Borgström; Leif Hammarström; Jan Davidsson; Sebastiano Campagna; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Artificial photosynthesis; Electron transfer; Energy transfer; Ruthenium; Manganese; Charge-separated state; Donor-acceptor; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : This thesis describes an interdisciplinary project, where the aim is to mimic the initial reactions in photosynthesis. In photosynthesis, the absorption of light is followed by the formation of charge-separated states. The energy stored in these charge-separated states is further used for the oxidation of water and reduction of carbon dioxide. LÄS MER

  7. 25. Modal Analysis of Supersonic Flow Separation in Nozzles

    Författare :Ragnar Larusson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Separated Nozzle Flow; Dynamic Mode Decomposition; Hybrid RANSLES; CFD; Modal Analysis; Arnoldi;

    Sammanfattning : Operating a convergent-divergent nozzle under overexpanded conditions can lead to supersonic flow separation in the divergent section of the nozzle. In this case, an attached oblique shock wave forms at the separation base. LÄS MER
