  1. 1. Fysisk aktivitets effekt på fatigue hos barn och unga vuxna med cancer

    Kandidat-uppsats,

    Författare :Jonna Olsson; Cajsa Gredenhag; [2022-01-18]
    Nyckelord :fysisk aktivitet; barn och unga vuxna; cancer; fatigue;

    Sammanfattning : Bakgrund: Varje dag i Sverige drabbas ett barn av cancer. Med cancerdiagnosen kommer många förändringar i barnets liv relaterat till behandlingar, symtom och biverkningar. Fatigue är ett symtom som många cancersjuka patienter upplever, både före och efter behandling. LÄS MER

  2. 2. ESTIMATION OF RADIATION EXPOSURE FROM NATURALLY OCCURRING RADIONUCLIDES IN FOOD AND FOODSTUFF

    Master-uppsats,

    Författare :Ida Bengtsson; [2022-01-13]
    Nyckelord :Medical physics; Naturally occurring radionuclides; committed effective dose from ingested radionuclides; Biokinetic models;

    Sammanfattning : Purpose: The main purpose of this study was to provide an estimation of the committed effective dose received by the Swedish population from naturally occurring radionuclides (NORM) in the diet. This study was also aiming to investigate the impact on the committed effective dose due to the new developments in the biokinetic model for Po 210 . LÄS MER

  3. 3. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector

    Master-uppsats,

    Författare :Victor Asp; [2022-01-13]
    Nyckelord :Medical physics; whole-body bone scans; gamma camera; Cadmium Zinc Telluride detector;

    Sammanfattning : The bone scan is a common nuclear medicine imaging procedure that is mainly used for evaluating several oncological patient groups. A radioactive tracer, 99mTc -labelled diphosphonate, is injected intravenously and accumulates in the skeleton. The distribution of the tracer in the body is measured with a gamma camera 3 hours post-injection. LÄS MER

  4. 4. Establishment of a deep learning algorithm for dosimetry of radiopharmaceuticals

    Master-uppsats,

    Författare :Dennis Lipnicevic; [2022-01-13]
    Nyckelord :Medical physics; automated segmentation; dosimetry; kidney; nuclear medicine dosimetry; deep learning; convolutional neural network;

    Sammanfattning : Purpose: The aim of this study was to introduce a volumetric convolutional neural network for segmentation of the kidneys in SPECT images and to apply it in the dosimetry of radiopharmaceuticals of this organ, in order to decrease segmentation time and to standardize the segmentation of the kidneys. Method: Three networks were trained using two network architectures and a total of 216 retrospectively collected images from patients that underwent imaging procedures at Sahlgrenska University Hospital between 2009 and 2018.

  5. 5. Comprensión Auditiva con Material Audiovisual : Las percepciones de estudiantes sobre el uso de video en la enseñanza de lenguas extranjeras

    Kandidat-uppsats, Umeå universitet/Institutionen för språkstudier

    Författare :Sandra Davidsson; [2022]
    Nyckelord :listening comprehension; video; teaching; foreign language; multimodal; extensive listening; body language; audiovisual; hörförståelse; video; undervisning; främmande språk; multimodalt; omfattande lyssnande; kroppsspråk; audiovisuellt; comprensión auditiva; video; enseñanza; lengua extranjera; multimodal; escucha extensiva; lenguaje corporal; audiovisual;

    Sammanfattning : El presente estudio examina las percepciones de los estudiantes sobre el uso del video en una actividad de comprensión auditiva. La actividad se llevó a cabo con 22 estudiantes de noveno grado que habían estado estudiando español desde el sexto grado en una escuela primaria sueca. LÄS MER
