  1. 21. Proton radiotherapy spot order optimization to maximize the FLASH effect

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Oscar Widenfalk; [2023]
    Keywords : Radiotherapy; Optimization; FLASH;

    Abstract : Cancer is a group of deadly diseases, to which one treatment method is radiotherapy. Recent studies indicate advantages of delivering so-called FLASH treatments using ultra-high dose rates (> 40 Gy/s), with a normal tissue sparing FLASH effect. READ MORE

  3. 22. 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).

  4. 23. Fast Simulations of Radio Neutrino Detectors : Using Generative Adversarial Networks and Artificial Neural Networks

    University essay from Uppsala universitet/Högenergifysik

    Author : Anton Holmberg; [2022]
    Keywords : Askaryan emission; Radio detection of neutrinos; in-ice propagation; neutrino; Generative adversarial networks; GAN; WGAN; Neural networks; NN; surrogate model; IceCube; deep learning; generative model;

    Abstract : Neutrino astronomy is expanding into the ultra-high energy (>1017eV) frontier with the use of in-ice detection of Askaryan radio emission from neutrino-induced particle showers. There are already pilot arrays for validating the technology and the next few years will see the planning and construction of IceCube-Gen2, an upgrade to the current neutrino telescope IceCube.

  5. 24. Purification of Engineered Graphite for Advanced Application

    University essay from KTH/Materialvetenskap

    Author : Lingfeng Zhao; [2022]
    Keywords : Graphite; Purification; Acid washing; Biomass; Biochar;

    Abstract : Graphite has important applications in several key industries, which has been listed as a “criticalraw material” considered to be supply-risk by European since 2020. Purification of engineered graphite is one of the essential processes for the manufacturing of high-quality graphite. READ MORE

  6. 25. Evaluation of the treatment planning system decimal ElectronRT and custom-made bolus for FLASH-irradiation

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Mizgin Coskun; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: The novel external beam therapy technique using ultra-high dose rates known as FLASH has become known for its normal tissue sparing effect. Currently in Lund, veterinary clinical trials are carried out on canine patients using electrons with ultra- high dose rates. READ MORE
