  1. 1. Röntgenremissens kvalité : - Faktorer som har påverkan i berättigandeprocessen

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för hälsovetenskap; Luleå tekniska universitet/Institutionen för hälsovetenskap

    Författare :Mimmi Blomberg; Elin Karlsson; [2020]
    Nyckelord :radiology referral; quality; justification; radiography; referring physician; röntgenremiss; kvalité; berättigande; radiografi; remittent;

    Sammanfattning : Introduktion: Alla röntgenundersökningar med joniserande strålning ska vara berättigade och optimerade. Detta kräver röntgenremisser av god kvalité. Syfte: Syftet med litteraturöversikten var att beskriva faktorer som har påverkan i röntgenremissens berättigandeprocess. LÄS MER

  2. 2. What is concealed from the eye of the beholder : A technical analysis of Amor and Psyche

    Master-uppsats, Stockholms universitet/Institutionen för kultur och estetik

    Författare :Teresia Strömgren; [2020]
    Nyckelord :Technical Art History;

    Sammanfattning : The oil on canvas painting Amor and Psyche attributed to Flemish artist Denys Calvaert in 1568 has subdued UV, IR and X-ray analysis. The result of these multispectral analysis provided a point of departure from the concept of materiality for further reasoning regarding: attribution, provenience, art period, display and panting technique.

  3. 3. Hybrid walnut : results from a five year field trial in southwest Sweden 2015-2020

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Stefan Juravle; [2020]
    Nyckelord :hybrid walnut; NG23; NG38; fertilization; fork; future crop tree; nurse trees;

    Sammanfattning : A crossbreeding between american black walnut and Persian walnut lead to the development of a hybrid walnut (Juglans x intermedia). In a field trial from southwest Sweden have been tested the impact of different levels of nurse trees, fertilization and weed control on the early growth of two hybrid walnut varieties: NG23 and NG38.

  4. 4. Self-Stabilizing Platform

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :MARCUS AKKILA; BIX ERIKSSON; [2020]
    Nyckelord :Mechatronics; PID controller; Control theory; Arduino; Servomotor; Inertial measurement unit; Self stabilization; Mekatronik; PID-regulator; Reglerteknik; Arduino; Servomotor; Tröghetssensor; Självstabilsering;

    Sammanfattning : This project explores the possibility to stabilize a hand held serving-tray using a micro-controller, two servomotors and an inertial measurement unit (IMU). It is heavily focused on control theory, specifically using a PID controller. LÄS MER

  5. 5. Modelling of a Liquid Metal Loop System : For X-ray Applications

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Anton Persson; [2020]
    Nyckelord :;

    Sammanfattning : A closed system of a liquid metal jet loop operating in vacuum is modelled and investigated using a commercial 1D simulation tool. Possible methods to approximate a free-falling jet in vacuum to capture the behavior of the system in 1D is investigated. LÄS MER
