  1. 1. Do selected CF3-containing pharmaceuticals oxidize to trifluoroacetic acid (TFA)? – Analysis of ultra-short perfluoroalkyl acids (PFAAs) and their analytical challenges following oxidation

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Johanna Gillberg; [2022]
    Keywords : ;

    Abstract : Total oxidizable precursor assay (TOPA) has been used to understand the contribution of unknown precursors to the extractable organofluorine (EOF) compounds. The investigation of compounds containing a CF3 moiety especially connected to an aromatic ring is important because any compounds with such a moiety (pharmaceuticals) may oxidize to form trifluoroacetic acid (TFA).

  3. 2. Creating Bushing Core Geometries

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Hanna Damsgaard Falck; Johanna Ring; Erik Svensson; [2021]
    Keywords : COMSOL; Bushing; Geometry; Appliaction Builder; Model Builder; Excel; Livelink;

    Abstract : Bushings are a necessary component of the transformers in the power grid. A bushing is used to control the electric field's strength and shape. It is also an insulator for high-voltage conductors. The bushing enables a conductor to be safely brought through a grounded barrier. READ MORE

  4. 3. Mycotoxins – an increasing problem? : the effects of climate changes on Fusarium mould populations and the occurrence of fusaro toxins in Swedish cereals

    University essay from SLU/Department of Molecular Sciences

    Author : Johanna Janhager; [2018]
    Keywords : Fusarium spp.; fusarotoxins; climate change; Sweden; cereals; food safety;

    Abstract : Future changes in climate are expected to affect Sweden in the form of an up to 40 % increase in precipitation and a mean temperature that will be elevated by 3 - 4.5 °C by the end of the 21st century. These are conditions that presumably favour growth of Fusarium moulds. READ MORE

  5. 4. A lab-on-a-chip device for photonic sensing of single cells
