    Abstract : During the pressing of powder mixtures to make cemented carbide tools, the degree to which the powder spreads to fill the die and to which it compacts is uncertain. This leads to inconsistent dimensions and densities in the finished product. READ MORE

  5. 4. Hydrodynamic Modelling of Spread of Perfluoroalkyl Octanoic Sulphonate and Perfluoroalkyl Hexanoic Sulphonate in Lake Ekoln

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Prajwol Prajapati; [2022]
    Keywords : Hydrodynamic modelling; water quality; PFAS; PFOS; PFHxS; MIKE 3 FM; Ekoln; Fyrisån;

    Abstract : Per and polyfluoroalkyl substances (PFAS) are found ubiquitously in the environment across the globe.These substances have high persistence due to the strong carbon and fluorine bond. In the aquaticenvironment, due to high persistence, these substances don’t decay easily and are detected on the surfaceas well as in groundwater sources. READ MORE
