  1. 1. Method development for the analysis of PFAS and neutral precursors in active and passive air samplers

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Pascal Camoiras González; [2019]
    Keywords : ;

    Abstract : Poly- and perfluoroalkyl substances (PFAS) are a chemical class of global concern because of their persistence, toxicity and widespread presence in the environment. This work aimed to develop a robust and reliable method to analyse perfluorohexane sulfonic acid (PFHxS), perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), as well as the neutral volatile PFOS precursors, namely perfluorooctane sulfonamides and perfluorooctane sulfonamidoethanols (FOSAs/FOSEs).

  3. 3. REAL-TIME RENDERING OF DEFORMABLE SNOW COVERS

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Josefin Svensson; [2019]
    Keywords : ;

    Abstract : Rendering snow environments in real-time requires e‚ffective methods for representing the snow and its properties. ‘This thesis explores methods for rendering deformable snow covers, where a dynamic heightfi€eld is used for storing snow heights.
