  2. 1. Experimental and Clinical Studies on Contact Allergy to Diphenylmethane-4,4′-diisocyanate and Related Substances

    Author : Haneen Hamada; Yrkes- och miljödermatologi; []
    Keywords : 4; 4′-MDI; freund s complete adjuvant; Guinea pig maximization test; 4; 4 -MDA; 4; 4 -DMDA; 4; 4 -DMDI; PPD; p-phenylenediamine; 2; 4-TDI; Toluene diisocyanate; trimer; FCA; Cross-reactivity; dermal uptake; contact allergy; contact dermatitis;

    Abstract : The exposure to isocyanates is more of an occupational problem than a consumer problem. The main route of exposure is assumed to be through inhalation. Isocyanates that have high vapor pressure, such as TDI, can be airborne at room temperature. Other isocyanates such as MDI are volatile only when heated. READ MORE

    Abstract : Globalisation and technological digitisation have triggered an Industry 4.0. revolution.  The core of this revolution is autonomisation of complex processes, which require expert knowledge. READ MORE

  5. 3. The Complex World of Superstrings : On Semichiral Sigma Models and N=(4,4) Supersymmetry

    Author : Malin Göteman; Ulf Lindström; Daniel Waldram; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-linear sigma models; extended supersymmetry; semichiral superfields; neutral hyperkähler geometry; generalized Kähler geometry; T-duality; vector multiplets; Theoretical Physics; Teoretisk fysik;

    Abstract : Non-linear sigma models with extended supersymmetry have constrained target space geometries, and can serve as effective tools for investigating and constructing new geometries. Analyzing the geometrical and topological properties of sigma models is necessary to understand the underlying structures of string theory. READ MORE

  6. 4. Transformation of iron constituents during early diagenesis : in situ studies of a Baltic Sea sediment-water interface

    Author : C. H. Magnus Lindström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aim of the present study was to elucidate the mechanisms and kinetics of the transformation of iron constituents at the sediment-water interface and their interaction with other element cycles during early diagenesis, with emphasis on their relations with oxygen, phosphorus and sulphur. The investigation was carried out in situ at 10 m water depth on a nearshore Baltic Sea soft bottom sediment. READ MORE

  7. 5. Beyond the Party’s Realm - The Consequences of Variation in Candidate Selection

    Author : Jana Schwenk; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; candidate selection; corruption; valence; female representation;

    Abstract : In the last two decades, Western European parties have introduced various methods to select candidates for executive public office. A process that before was mainly the privilege of a narrow elite was opened to party members in several parties. READ MORE
