  2. 1. Geochemical and mineralogical laboratory methods in waste rock drainage quality prediction

    Author : Teemu Karlsson; Lena Alakangas; Päivi Kauppila; Andrew Barnes; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extractive waste characterisation; drainage water; ARD; NRD; ABA test; NAG test; SEM; Applied Geochemistry; Tillämpad geokemi;

    Abstract : Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. READ MORE

  4. 2. The diagnostic potential of the He I D3 spectral line in the solar atmosphere

    Author : Tine Libbrecht; Jaime de la Cruz Rodríguez; Jorrit Leenaarts; Göran Scharmer; Valentín Martínez Pillet; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sun; Line formation; Chromosphere; Spectro-Polarimetry; Flares; Reconnection; Astronomy; astronomi;

    Abstract : The research question of my PhD is in a way a simple one: what can observations of the He I D3 line teach us about the solar chromosphere? This optical spectral line at 5876 Å is generally formed in the upper chromosphere, and is sensitive to the local magnetic field. The He I D3 line is also indirectly sensitive to heating of the transition region and corona, since it is resulting from a transition that occurs between levels in the triplet system of neutral helium.

  5. 3. Producing, Preventing, and Explaining Persistent Complex Subliminal Stimulation Effects

    Author : Andreas Birgegård; Staffan Sohlberg; Mario Mikulincer; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Subliminal stimuli; persistent effects; attachment; relational schema; ethics; debriefing; interaction; motivation; sex differences; Psykologi; Psychology; Psykologi;

    Abstract : Strong recent focus on unconscious processes has increased interest in subliminal stimulation and similar experimental technologies. Assumptions about the persistence of effects of unconscious stimulation are generally conservative, referring to seconds or minutes (Silverman, 1977; Velmans, 1991). READ MORE

  6. 4. Essays on Financial Markets and the Macroeconomy

    Author : Jürg Fausch; Roine Vestman; John Hassler; Ilan Cooper; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Asset pricing; business cycles; DSGE model; macroeconomic risk; monetary policy shocks; recursive preferences; stock market; VAR model; variance decomposition; Economics; nationalekonomi;

    Abstract : Asset pricing implications of a DSGE model with recursive preferences and nominal rigidities. I study jointly macroeconomic dynamics and asset prices implied by a production economy featuring nominal price rigidities and Epstein-Zin (1989) preferences. READ MORE

  7. 5. Effect of metal ion irradiation on hard coating synthesis by physical vapor deposition

    Author : Tun-Wei Hsu; Magnus Odén; Grzegorz Greczynski; Sven Ulrich; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aim of this thesis is to understand and control how the ions in the plasma influence the film growth during thin film deposition processes. Two physical vapor deposition (PVD) techniques are investigated, namely magnetron sputtering and cathodic arc evaporation. READ MORE
