  2. 21. Remediation of TNT-contaminated water by using industrial low-cost residue pine bark

    Author : Olga Chusova; Emma Nehrenheim; Monica Odlare; Jaquiline Akhavan; Mälardalens högskola; []
    Keywords : Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : In the process of demilitarization of explosives, army ammunition plants generate a waste stream known as pink water. The principal component of the wastewater is the nitro-aromatic compound 2,4,6-trinitrotoluene (TNT). READ MORE

  4. 22. Charge dynamics and electronic structure of pi-conjugated systems

    Author : Åsa Johansson; Michael Springborg; Linköpings universitet; []
    Keywords : ;

    Abstract : The research presented in this theses deals with the electronic properties of 1rconjugated molecular systems. Charge dynamics has been studied in order to get a better understanding of the physical processes behind charge transport in these materials, intended to be used in organic molecular electronic devices.

  5. 23. Modeling of Combustion, Mixing and Heat Transfer in Oxy-Fuel CFB Power Plants

    Author : Sadegh Seddighi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : An important contribution to anthropogenic emissions of CO2 is from electricity generation, i.e. emissions from large fossil fuelled power plants. Carbon Capture and Storage technologies offer the possibility for continued use of fossil fuels while almost eliminating the CO2 emissions. READ MORE

  6. 24. Genomic and morphological diversity of marine planktonic diatom-diazotroph associations : a continuum of integration and diversification through geological time

    Author : Andrea Caputo; Rachel Ann Foster; Monika Quinones Winder; Ramon Massana; Stockholms universitet; []

    Abstract : Symbioses between eukaryotes and nitrogen (N2)-fixing cyanobacteria (or diazotrophs) are quite common in the plankton community. A few genera of diatoms (Bacillariophyceae) such as Rhizosolenia, Hemiaulus and Chaetoceros are well known to form symbioses with the heterocystous diazotrophic cyanobacteria Richelia intracellularis and Calothrix rhizosoleniae.

  7. 25. Optimization Methods for Robust Control with Application to Resistive Wall Modes in Tokamaks

    Author : Carl-Magnus Fransson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H?; fusion; QFT; performance; tokamak; optimization; robustness; structured singular value; control; plasma; resistive wall modes; LMI; PID control;

    Abstract : In many research areas physical systems are described by mathematical models. We focus here on systems that are regulated by a controller, typically realized by software, whose design involves certain parameters. READ MORE
