  1. 1. Vikten av patientinformation inför en MR-undersökning : En litteraturstudie

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för hälsa, lärande och teknik

    Författare :Helena Alexandersson; Amanda Larsson; [2021]
    Nyckelord :Magnetic resonance imaging; questionnaires; communication; patient; information; appointment letter; experience; Professional patient relation; Magnetkameraundersökning; frågeformulär; kommunikation; patient; information; mötesbrev; erfarenhet; personal-patient relation;

    Sammanfattning : Inledning: Bristfällig information till patienterna inför en MR-undersökning kan leda till att patienterna blir nervösa, stressade och känner obehag och därmed uteblir från bokade tider eller väljer att avbryta sina undersökningar i förtid. Med en tydlig information till patienten innan MR-Kaundersökningen startar ökar det patientens förståelse inför besöket. LÄS MER

  3. 2. Have Radial Velocity Surveys Missed Any Planets?

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Författare :Shah Raj; [2021]
    Nyckelord :radial velocity survey; transit method; exoplanet; habitable zone; habitable zone boundaries; HZ; early Mars; recent Venus; stability; instability; chaos; REBOUND; MEGNO; MEGNO maps; Hill sphere; stable systems; unstable systems; Physics and Astronomy;

    Sammanfattning : The project was aimed at numerically assessing exoplanetary systems to distinguish their capabilities of hosting additional planets. The shortcomings of the radial velocity method sometimes causes hindrance in the detection of terrestrial planets. LÄS MER

  4. 3. Capture into mean motion resonance

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Kaltrina Kajtazi; [2021]
    Nyckelord :MMR; Mean motion resonance; Planetary dynamics; First order MMR; Numerical integration with N-body; Physics and Astronomy;

    Sammanfattning : Orbital or mean motion resonance (MMR) occurs when the orbital period ratio between two planets is close to a ratio of small integers. MMR can protect planets from collisions and affects the overall final architecture of the system. LÄS MER

  5. 4. Mean Motion Resonances and Planetary Scattering

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Erik Dahlöf; [2018]
    Nyckelord :mean motion resonance; orbit resonance; planetary dynamics; planet-planet scattering; planetary scattering; eccentricity; inclination; planet systems; disturbing force; orbit dynamics; orbital elements; planets; exoplanets; scattering phase; relaxation; dynamical instabilities; N-body; protoplanetary disk; planet migration; eccentricity damping; inclination damping; planet-disk interactions; Physics and Astronomy;

    Sammanfattning : The observed distribution of giant exoplanet eccentricities and inclinations are significantly larger than what is measured for their Solar system analogues, Jupiter and Saturn. Since the first observations of exoplanets, planet-planet scattering has been proposed as a possible mechanism for exciting the eccentricities and inclinations of giant exoplanets. LÄS MER

  7. 5. Automatic Alignment of 2D Cine Morphological Images Using 4D Flow MRI Data

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Victoria Härd; [2016]
    Nyckelord :;

    Sammanfattning : Cardiovascular diseases are among the most common causes of death worldwide. One of the recently developed flow analysis technique called 4D flow magnetic resonance imaging (MRI) allows an early detection of such diseases. LÄS MER
