  1. 1. Dual Energy CT as a Foundation for Proton Therapy Treatmen Planning - A pilot study

    University essay from Umeå universitet/Institutionen för fysik

    Author : Torbjörn Näsmark; [2019]
    Keywords : Dual Energy CT; DECT; Computed Tomography; CT; Proton Therapy; Skandion;

    Abstract : The treatment plan for radiation therapy with protons is based on images from a computed tomography (CT) scanner. This is problematic since the photons in the x-ray beam from the CT scanner and the protons are affected differently by the tissue in the patient, which introduce an uncertainty in the track length of the protons.

  2. 2. Modeling and Analysis of the Shot Peening Process : a Study of the Residual Stresses in an Insert using the Finite Element Method

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Hamid Torkaman; [2018]
    Keywords : Shot peening; Residual stresses; Cutting tool inserts; Post-coating treatment; Coated cemented carbide;

    Abstract : Cutting tool inserts are often coated with thin layers either through chemical vapor deposition (CVD) or physical vapor deposition (PVD) processes. In order to have a better wear resistance cutting tools are mostly subjected to post-coating treatment processes. READ MORE

  3. 3. End-of-life scenarios for bioplastic food and drinking packages : a study of Swedish bioplastic waste disposal habitsand environmental impacts

    University essay from SLU/Department of Molecular Sciences

    Author : Tilda Hansson; [2018]
    Keywords : bioplastic; biodegradable plastic; compostable plastic; biobased plastic; PLA; Bio-PET; consumer;

    Abstract : The aim of this study was to investigate real end-of-life scenarios for some of the most common bioplastics, such as PLA and Bio-PET, for food and drinking packages in Sweden and to evaluate some of the potential environmental consequences of these scenarios. Life Cycle Analysis often evaluate intended end-of-life scenarios for bio-plastic products, but this study used an explorative research method, gathering infor-mation of the conduction and habits of bioplastics to evaluate if these scenarios were the ones occurring.
