    Sammanfattning : Este estudio evalúa actitudes lingüísticas de profesores de español como lengua extranjera en Suecia hacia formas de género neutral en diferentes contextos y formatos, centrándose en las innovaciones morfológicas -e, -x, -@ así como en el desdoblamiento. Igualmente, compara la actitud entre profesores de lengua materna española y sueca. LÄS MER

  3. 2. Evaluating aperture shape controller (ASC) in modulated radiation treatments

    Master-uppsats,

    Författare :Vilma Andrén Cederholm; [2023-09-28]
    Nyckelord :Medical physics;

    Sammanfattning : To decrease aperture complexity, the aperture shape controller (ASC) is a recently introduced function in Eclipse external beam planning (Varian Medical Systems, Palo Alto, USA). ASC works within the photon optimizer, minimizing distances between adjacent leaf tips of the MLC. LÄS MER

  4. 3. Governance for Climate Change Adaptation in transboundary conservation areas A case study of La Amistad International Park (Pacific Side) between Costa Rica and Panama

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Ana Monroy Chaparro; [2023]
    Nyckelord :Climate change adaptation; Multilevel Governance; Transboundary conservation area; La Amistad International Park PILA; Earth and Environmental Sciences;

    Sammanfattning : El cambio climático es un problema global urgente que afecta a millones de personas y diversos ecosistemas. Sin embargo, existe una brecha significativa entre lo que se ha hecho y lo que es necesario para la adaptación al cambio climático. LÄS MER

  5. 4. Uncertainties in the use of synthetic CT (sCT) for daily online adaptive radiotherapy for lung cancer

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Johansson Vivika; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background and purpose: Cone Beam Computed Tomography (CBCT) based online adaptive radiotherapy (oART) has been clinically implemented for several anatomical sites worldwide. However, random and abrupt anatomical changes with large density alterations can occur in lung patients, leading to uncertainties with synthetic computed tomography (sCT) and dose calculation.

  7. 5. Evaluation of the iterative kilovoltage cone-beam computed tomography reconstruction method for the Varian TrueBeam system

    Master-uppsats,

    Författare :Tamana Haidari; [2022-03-18]
    Nyckelord :Medical physics; FDK algorithm; iterative algorithm; CBCT; image quality;

    Sammanfattning : Introduction: Radiotherapy is used to treat patients with various types of cancer, where linear accelerators produce the radiation beam used for the treatment. Before each treatment fraction, the patient needs to be correctly positioned according to the treatment plan. LÄS MER
