  1. 11. On the Branch Loci of Moduli Spaces of Riemann Surfaces

    Author : Gabriel Bartolini; Milagros Izquierdo; Allen Broughton; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The spaces of conformally equivalent Riemann surfaces, Mg where g ≥ 1, are not manifolds. However the spaces of the weaker Teichmüller equivalence, Tg are known to be manifolds. The Teichmüller space Tg is the universal covering of Mg and Mg is the quotient space by the action of the modular group. READ MORE

  2. 12. Co-rotational beam elements in instability problems

    Author : Jean-Marc Battini; KTH; []
    Keywords : instability; co-rotational mehtod; branch-switching; beam element; warping; plastic buckling. post-bifurcation; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The purpose of the work presented in this thesis is to implement co-rotational beam elements and branch-switching procedures in order to analyse elastic and elastoplasticinstability problems. For the 2D beam elements, the co-rotational framework is taken from Crisfield [23]. READ MORE

  3. 13. Asymptotic Giant Branch stars viewed up-close and far-off : The physics, chemistry, and evolution of their circumstellar envelopes

    Author : Matthias Maercker; Hans Olofsson; Fredrik L. Schöier; Laurentius B. F. M. Waters; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AGB stars; evolution; mass-loss; abundances; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : The asymptotic giant branch (AGB) is the last stage of stellar evolution for stars with masses between 0.8-8 M(sun). This phase is characterised by an intense mass loss, which builds up a circumstellar envelope of dust and gas(CSE). It is through this process that the AGB stars contribute to the chemical evolution of galaxies. READ MORE

  4. 14. Characteristics of BVOC emissions from a Swedish boreal forest : Using chambers to capture biogenic volatile organic compounds (BVOCs) from trees and forest floor

    Author : Min Wang; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BVOCs; boral forest; Norway spruce; forest floor; branch chamber; soil chamber;

    Abstract : Plant-emitted biogenic volatile organic compounds (BVOCs) are a large group of hydrocarbons released by plant leaves, bark, flowers and fruits into the atmosphere and from plant roots into the soil. BVOCs have important physiological and ecological functions, such as mediating within-plant and plant-plant communication, defense against herbivores attack, protection against heat or other oxidative stress, attracting pollinators etc. READ MORE
