1. 26. When and why is pre-treatment of substrates for anaerobic digestion useful?

   Författare :My Carlsson; Hinrich Uellendahl; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

   Sammanfattning : Anaerobic digestion (AD) plays a key role in the recovery of renewable energy, in the form of biogas, and nutrients from waste materials. Pre-treatment of AD substrates has the potential to improve process performance in terms of increased methane yield and solids reduction, but pretreatments are not yet widely implemented into full-scale AD systems.

3. 27. Microbial Treatment of Heavy Metal Leachates

   Författare :Teresa Alvarez Aliaga; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Environmental technology; algal-bacterial symbiosis.; metal precipitation; biosorption; biogenic sulphide; municipal and agricultural solid wastes organic matter degradation; sulphate-reducing bacteria; Bioremediation; heavy metals removal; Miljöteknik; kontroll av utsläpp; Biotechnology; Bioteknik;

   Sammanfattning : Ore-mining, metallurgy and other industrial activities represent the source of heavy metal and radionuclide contamination in terrestrial and aquatic environments. Physico-chemical processes are employed for heavy metal removal from industrial wastewater. LÄS MER

4. 28. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery

   Författare :Vladimir Kirejev; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photodynamic therapy; PDT enhancement; Nitric oxide; NO-based PDT; Targeted drug delivery; Galectin-3; mTHPP; Cyclodextrin; CD-mTHPP conjugate; PpIX AuNP combination; Two-photon microscopy; FLIM; Cell phototoxicity; Ex vivo skin;

   Sammanfattning : The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. This thesis explores different nanosystems with aim to improve PDT focusing on spectroscopic and ex vivo studies. LÄS MER

5. 29. System studies of Anaerobic Co-digestion Processes

   Författare :Eva Nordlander; Jinyue Yan; Eva Thorin; Krist Gernaey; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Production of biogas through anaerobic digestion is one pathway to achieving the European Union (EU) goals of reducing greenhouse gas emissions, increasing the share of renewable energy, and improving energy efficiency. In this thesis, two different models (Anaerobic Digestion Model No. LÄS MER

7. 30. Enhanced Biological Phosphorus Removal - Carbon Sources, Nitrate as Electron Acceptor, and Characterisation of the Sludge Community

   Författare :Magnus Christensson; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; nitrate; carbon source; PAO; polyphosphate accumulating organisms; enhanced biological phosphorus removal; EBPR; characterisation; Biotechnology; Bioteknik;

   Sammanfattning : Enhanced biological phosphorus removal (EBPR) was studied in laboratory scale experiments as well as in a full scale EBPR process. The studies were focused on carbon source transformations, the use of nitrate as an electron acceptor and characterisation of the microflora. LÄS MER
