  1. 1. " Optimization of Margins and Plan Robustness for Proton Therapy of Hodgkin’s Lymphoma"

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Filip Hörberger; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose/Background: Utilizing proton therapy (PT) for treatment of Hodgkin’s lymphoma (HL) has demonstrated favorable features, particularly a reduced dose to organs at risk (OAR) in comparison with photon radiotherapy. However, there is a coherent complexity with PT including its uncertainties, such as range-uncertainties and set-up variations as protons are highly sensitive to tissue density variations within the beam-path.

  3. 2. Precipitation behavior of the super austenitic stainless steel SANICRO® 35 and the effect on impact toughness and pitting corrosion resistance

    University essay from KTH/Materialvetenskap

    Author : Shunyi Li; [2022]
    Keywords : Super austenitic stainless steel; solid phase transformation; TTT diagram; impact toughness; critical pitting temperature; TC PRISMA simulation; Superaustenitiskt rostfritt stål; fastfasomvandling; TTT-diagram; slaghållfasthet; kritisk punktfrätningstemperatur; TC PRISMA simulering;

    Abstract : This research extended the knowledge of the solid phase transformation and the resulting influence on impact toughness and pitting corrosion resistance in super austenitic stainless steel (SASS) SANICRO® 35. A time-temperature-transformation diagram (TTT diagram) was assembled by performing isothermal heat treatments in the temperature range of 650-1050 °C for different periods of time, ranging from 5 min to 500 min.

  4. 3. Exploration of ways to utilize wheat chaff through fungal substrate conversion : a base for animal feed or substrate for cultivation of edible mushrooms

    University essay from SLU/Department of Molecular Sciences

    Author : Caroline Sandberg; [2022]
    Keywords : harvest residues; chaff; oyster mushroom; agro-waste reduction; mushroom production;

    Abstract : The shift towards a more sustainable food system emphasises a need for increased circularity and valorisation of available resources. Chaff constitutes one of three main fractions obtained upon harvest of certain crops, during which it is generally discarded on the field. READ MORE

  5. 4. PET Recycling – Material and Performance aspects

    University essay from KTH/Fiber- och polymerteknologi

    Author : Carl Höög; [2021]
    Keywords : PET-bottle; Recycling; Tensile Testing; Material properties; PET-flaska; återvinning; dragprovning; materialegenskaper;

    Abstract : Återvinning och insamling av PET-flaskor startade redan 1994 i Sverige och är en av de grundläggande återvinningsindustrierna.Teknologin har ständigt utvecklas sedan dess och vi har nu nya återvinningsmetoder som kan säkerställa PET-material som uppnår livsmedelskvalitet. READ MORE

  6. 5. Study of a valorisation process for biomass industrial waste involving acid cooking and enzymatic hydrolysis

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Nicolas Brunet; [2020]
    Keywords : ;

    Abstract : Lignocellulosic biomass has potential to chip in the chemical and biofuels supplies in future societies,even though lignocellulose is a recalcitrant structure that has to be treated in several steps. After theirproper life cycle, wood-derived materials such as particleboards have few outcomes today apart fromenergy recovery for heat production. READ MORE
