  1. 11. Composition and dynamics of the bacterial community in aerobic granular sludge reactors

    Författare :Enikö Barbara Szabo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; qPCR; sequencing batch reactors; microbial community composition; T-RFLP; functional groups; Illumina MiSeq; wastewater; aerobic granular sludge; nitrogen removal; population dynamics;

    Sammanfattning : The aerobic granular sludge (AGS) technology is probably the future standard for wastewater treatment, due to its low footprint and low energy consumption. Although achieving granulation is usually not a challenge anymore, our understanding of the community assembly during start-up, and of the microbial ecology of these reactors in general, is incomplete.

  3. 12. Developments and application of neutron noise diagnostics of sodium cooled fast reactors

    Författare :Florian Zylbersztejn; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutron monitoring; Neutron noise; Fast neutron reactors; Core volume fluctuations;

    Sammanfattning : The Sodium cooled Fast Reactor (SFR) is one of the six reactor types selected by the Generation-IV international forum (GIF), and the building of an industrial prototype is planned in France. The safety standard of the future SFR has to be equivalent to the EPR's. LÄS MER

  4. 13. Mixing patterns in Rushton-turbine-agitated reactors

    Författare :Fabrice Guillard; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; coherent mixing structure; geometrical analysis; dynamic structural analysis; conditional sampling; laser-induced fluorescence; mixing; stirred tank; Livsmedelsteknik;

    Sammanfattning : This Ph.D. Thesis concerns the study of mixing in Rushton turbine agitated reactors. In industrial (bio)reactors, mixing is recognised as a limiting factor that significantly affects the performance of the process. LÄS MER

  5. 14. Reactors - Circuit Theory and Silicon Integrated Applications

    Författare :Pietro Andreani; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Filters; Delay Lines; VCOs; Inductors; Circuit Theory; Capacitors; CMOS; Electronics; Elektronik;

    Sammanfattning : This dissertation deals with reactive components in electric circuits, both as targets for a theoretical circuit analysis, and as devices implemented in silicon processes like CMOS. The frequency behavior of a general electric network is determined by the reactances (i.e. LÄS MER
