  1. 1. Arbetsrelaterad stress hos röntgensjuksköterskor : En intervjustudie

    Kandidat-uppsats, Uppsala universitet/Institutionen för kirurgiska vetenskaper; Uppsala universitet/Institutionen för kirurgiska vetenskaper

    Författare :Jessica Jonsson; Sara Carlsson; [2019]
    Nyckelord :occupational stress; radiographer; work load; arbetsrelaterad stress; röntgensjuksköterska; arbetsbörda;

    Sammanfattning : Background: Healthcare professionals are often the subject to occupational stress, the professional radiographer is no exception. Occupational stress has been seen as a predictor to burn outs amongst radiographer and may jeopardise the patients’ safety during radiologic examinations. LÄS MER

  2. 2. Trace element analysis based on neutron activation with coincident gamma ray detection

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Författare :Jessica Delgado; [2017]
    Nyckelord :scintillator detectors; gamma ray; gamma radiation; spectrometer; neutron activation analysis; trace element; Physics and Astronomy;

    Sammanfattning : In this work, six soil samples have been analyzed. The samples come from different sedimentary layers on Earth. They were previously studied with the objective to find the trace concentration of iridium, to correlate the increased concentrations of iridium with meteorite impacts that have occurred on Earth.

  3. 3. Evaluation of methods to characterise the geochemistry of limestone and its fracturing in connection to heating

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Jessica Jennerheim; [2016]
    Nyckelord :geochemistry; limestone; Gotland; thermal properties; x-ray fluorescence; x-ray computed tomography; Earth and Environmental Sciences;

    Sammanfattning : Abstract: In 2011 Vinnova funded a joint project between Nordkalk AB, Kalkproduktion Storugns AB (KPAB) and the department of Geology at the University of Lund. The goal of the project is to increase the general knowledge of limestone and in extension, facilitate for the industry. LÄS MER

  4. 4. The effect of concurrent radiation and calcium in two cancer cell lines

    Master-uppsats, Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Jessica Billberg; [2016]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: Calcium is an important ubiquitous second messenger regarding the maintenance of cellular homeostasis, and is therefore tightly regulated. Calcium induces cell death when internalised into cancer cells after permeabilization of the cell membrane by electroporation. LÄS MER

  5. 5. The Primitive Antiarch Yunnanolepis from China : A Microtomographic Study

    Kandidat-uppsats, Uppsala universitet/Paleobiologi

    Författare :Jessica Grahn; [2016]
    Nyckelord :placodermi; microtomography; 3D model; mikrotomografi; 3D-modell;

    Sammanfattning : Placoderms appeared in the Silurian period and rapidly evolved and dominated the waters during the Devonian period. Among the earliest of the placoderms are yunnanolepids, a primitive form of antiarch from the Early Devonian of China and Vietnam. LÄS MER
