  1. 1. Review and Design of DC Electrical Field Measurement Systems and Related Developments : For Measurements Around HVDC Cable Terminations

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Emil Bergvall; [2023]
    Nyckelord :DC Field Probe; Measurement Systems; Electric Fields; Cable Termination; Ion Drift; Conductivity; HVDC; Field Mill; Field Simulations; Positioning System; MEMS; Electro-Optics; DC Fält Prob; Mätsystem; Elektriska Fält; Kabelavslut; Jondrift; Ledningsförmåga; HVDC; Fältkvarn; Fält Simulationer; Positioneringsystem; MEMS; Elektro-Optik;

    Sammanfattning : With power generation and consumption placed further away from each other, with for example increased offshore power production, the need for HVDC transmission systems increases. As voltage levels in the HVDC transmission system are raised, the losses can be decreased, enabling efficient power transfer over longer distances. LÄS MER

  3. 2. Purification of Engineered Graphite for Advanced Application

    Master-uppsats, KTH/Materialvetenskap

    Författare :Lingfeng Zhao; [2022]
    Nyckelord :Graphite; Purification; Acid washing; Biomass; Biochar;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Mizgin Coskun; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : 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. LÄS MER

  5. 4. Toxicity of Pulsed Beams in Radiation Therapy from a Physio-Chemical Perspective

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Karin Källén; [2021]
    Nyckelord :FLASH; radiotherapy; ultra high; dose rates; radiolysis; cancer; medical; FLASH; strålbehandling; ultrahög; doshastighet; radiolys; cancer; medicinsk;

    Sammanfattning : A significant portion of cancer patients receive radiotherapy as part of their curative or palliative treatment plan. Radiotherapy is however greatly limited by radiation induced toxicities in healthy tissue surrounding the tumour, which can lead to long-term or acute complications for a patient. LÄS MER

  7. 5. Plasmahalter av buprenorfin efter peroral och intravenös administrering till kanin

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

    Författare :Elina Thern; [2018]
    Nyckelord :Kanin; Buprenorfin; Peroral; Intravenös; Läkemedelsadministrering; Smärta; Smärtlindring; Analgesi; Farmakokinetik; Biotillgänglighet;

    Sammanfattning : I takt med att kaninens (Oryctolagus cuniculus) popularitet ökar och kravet på alltmer avancerad veterinärvård växer krävs kunskap om hur man smärtlindrar kanin på bästa sätt. Kaninen är ett utpräglat bytesdjur som döljer smärta väl, särskilt i stressade situationer som vid klinikvistelse. LÄS MER
