  1. 1. Use and Development of Diffusive Samplers to Analyse the Fate of Polycyclic Aromatic Compounds, Polychlorinated Biphenyls and Pharmaceuticals in Wastewater Treatment Processes

    Författare :Lijana Augulyte; Patrik L. Andersson; Anna Ledin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioavailable; biologically activated carbon; PRCs; sampling rate; SPMD; sorption; wastewater treatment; diffusive passive samplers; human pharmaceuticals; municipal sewage treatment plant; organic micropollutants; polycyclic aromatic compounds; PAHs; PCBs; POCIS; Environmental chemistry; Miljökemi;

    Sammanfattning : The efficiency of wastewater treatment systems is commonly measured by the reductions of parameters such as biological oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS) and/or reductions in levels of selected macro compounds (e.g. long-chained hydrocarbons and inorganic compounds).

  3. 2. Wood-derived lignin-based fibers as supercapacitor electrodes

    Författare :Azega Rajendra Babu Kalai Arasi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; lignin; green electrode materials; energy storage; supercapacitor;

    Sammanfattning : Today, in order to replace fossil energy sources with renewable energy sources such as solar and wind, reliable energy storage systems that can provide power regardless of the intermittent nature of the energy sources must be created. Especially with the future’s rising energy demands the development of such energy storage systems from green-collar materials with the least negative environmental impact is pressing. LÄS MER

  4. 3. Developmentof an immunosensor for enumeration of Nitrobacter

    Författare :Björn Sandén; KTH; []
    Nyckelord :;

    Sammanfattning : Eutrophication is a result of increasing discharges ofnutrients and is the main cause of the deterioration of theaquatic ecosystems. Major sources of nitrogen in coastal watersare wastewater treatment plants. LÄS MER

  5. 4. Verification of high energy photon therapy based on PET/CT imaging of photonuclear reactions

    Författare :Sara Janek Strååt; Anders Brahme; Cathrine Jonsson; Iuliana Dasu; Sibylle Ziegler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photonuclear reactions; PET CT treatment verification; High-energy photon therapy; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : For classical and intensity modulated radiation therapy of deep-seated tumors, high-energy photons are the optimal radiation modality from an integral dose point of view. By using narrow scanned beams the treatment outcome can be improved substantially by delivering biologically optimized intensity modulated distributions often with sharp dose gradients. LÄS MER

  7. 5. Transcriptomics and bioconcentration studies in fish to identify pharmaceuticals of environmental concern

    Författare :Filip Cuklev Stern; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fish; microarray; bioconcentration; pharmaceuticals; wastewater treatment; environment;

    Sammanfattning : Pharmaceuticals are frequently found in the aquatic environment. As they are most often highly biologically active, quite persistent and may accumulate in aquatic organisms, i.e. bioconcentrate, they may pose a risk to non-target organisms. LÄS MER
