  2. 1. Significance of transport dynamics on concentration statistics and expected mass fraction based risk assessment in the subsurface

    Author : Veljko Srzic; Vladimir Cvetkovic; Olaf A. Cirpka; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Local scale dispersion; Heterogeneity structure; Concentration moments; Moment collapse; Expected mass fraction;

    Abstract : This thesis relies on a Langrangian framework used for conservative tracer transport simulations through 2-D heterogeneous porous media. Conducted numerical simulations enable large sets of concentration values in both spatial and temporal domains. READ MORE

  4. 2. Companion wind shaping in binaries involving an AGB star

    Author : Lam Doan; Sofia Ramstedt; Eric Lagadec; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AGB and post-AGB stars; mass-loss; radio lines; binaries; wind shaping; Astronomy; Astronomi;

    Abstract : Stars of initial masses between 0.8-8 M☉ will become "asymptotic giant branch" (AGB) stars during the final stages of their evolution. During this phase, the stars are characterized by low velocity and high-density winds. READ MORE

  5. 3. 14C Produced by Nuclear Power Reactors - Generation and Characterization of Gaseous, Liquid and Solid Waste

    Author : Åsa Magnusson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; waste disposal; spent ion-exchange resins; mass balance assessment; Nuclear physics; environmental impact; Fysicumarkivet A:2007:Magnusson; nuclear power plant; Kärnfysik; Carbon-14;

    Abstract : This thesis presents the results from studies on carbon-14 produced by nuclear power reactors. Radioactive 14C enters the carbon cycle and can be taken up by humans, where it will constitute a potential health hazard. READ MORE

  6. 4. Production and application of fine fractions made of chemical pulp for enhanced paperboard strength

    Author : Elisabeth Björk; Per Engstrand; Mark Martinez; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : For all kinds of paperboard packages, the bending stiffness of the paperboard is a crucial property. In multi-ply folding boxboard (FBB) grades, this is obtained by placing different stocks in the outer and centre plies of the board. In the outer plies, a stock with a high tensile stiffness is used, typically made from refined kraft pulp fibres. READ MORE

  7. 5. Ribosomes and subunits from Escherichia coli studied by asymmetrical flow field-flow fractionation

    Author : Mikael Nilsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; VHb; Vitreoscilla hemoglobin; E. coli; Escherichia coli; separation; subunits; ribosomes; Asymmetrical flow field-flow fractionation; flow FFF; optimization; biotechnological production; Analytical chemistry; Analytisk kemi;

    Abstract : In this thesis asymmetrical flow field-flow fractionation (FFF) separations of ribosomes and subunits have been studied. Ribosomal material was prepared from Escherichia coli (E. coli) cells and analyzed by the size separation technique. READ MORE
