    Author : Eva-Maria Ekstrand; Bo H Svensson; Annika Björn (Fredriksson); David Bastviken; Jukka Rintala; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulp and paper; anaerobic digestion; fibre sludge; activated sludge; condensates; bleaching wastewater; wastewater treatment; methane; degradability; nutrient recirculation; Pappers- och massa; anaerob nedbrytning; fiberslam; aktivt slam; kondensat; vattenrening; metan; nedbrytbarhet; näringsåterföring;

    Abstract : The pulp and paper industry is a large producer of wastewater and sludge, putting high pressure on waste treatment. In addition, more rigorous environmental legislation for pollution control and demands to increase the use of renewable energy have put further pressure on the pulp and paper industry’s waste treatment, where anaerobic digestion (AD) and the production of methane could pose a solution.

  4. 2. Ultracold atoms in optical potentials : from noise-induced transport to superfluidity

    Author : Martin Zelan; Claude Dion; Sile Nic Chormaic; Umeå universitet; []
    Keywords : Brownian motors; noise-induced transport; superfluidity; ultracold atoms; optical potentials; optical lattices; laser coooling; fysik; Physics;

    Abstract : In this thesis, both experimental studies and numerical simulations of ultracold atoms in optical potentials are presented in a collection of nine scientific papers. In particular, noise-induced transport in dissipative optical lattices and superfluid properties of Bose-Einstein condensates have been studied. READ MORE

  5. 3. Higher Order Calculations for Low Energy Precision Physics

    Author : Nils Hermansson Truedsson; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Effective Field Theory; Chiral Perturbation Theory; The Muon Anomalous Magnetic Moment; Lattice Gauge Theory; Finite Volume Effects; Fysicumarkivet A:2019:Hermansson; Effektiv fältteori; Kiral störningsräkning; Myonens anomala magnetiska moment; Gitter-gaugeteori; Ändlig-volymkorrektioner;

    Abstract : This thesis concerns higher order calculations needed for precision physics in the low energy region of particlephysics. Of the four papers it contains, the first two introduce calculations at order p8 in the power countingof chiral perturbation theory, which is an effective field theory of QCD at low energies.
