  1. 1. Preeclampsia and the Brain : Epidemiological and Magnetic Resonance Studies

    Författare :Maria Nelander; Johan Wikström; Anna-Karin Wikström; Inger Sundström Poromaa; Gerda Zeeman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preeclampsia; eclampsia; seizure; MRI; MRS; IVIM; dementia; cardiovascular disease; magnesium; cerebral organic osmolytes; perfusion; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Preeclampsia is a pregnancy specific syndrome that causes substantial maternal and fetal morbidity and mortality. One major contributor to maternal deaths is eclampsia, i.e. when seizures arise in the context of preeclampsia. LÄS MER

  3. 2. Theoretical Studies of Atomic Structure, Radiative Transitions and Interference Effects

    Författare :Martin Andersson; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; Computational physics; Zeeman; Transition rate; Lifetime; Hyperfine structure; Interference; Atomic structure;

    Sammanfattning : Theoretical calculations concerning the advanced understanding of atomic structure and transitions has been performed for some atomic systems. The importance of different types of correlation depending on system has been investigated both using relativistic and non-relativistic quantum mechanics. LÄS MER

  4. 3. Modeling the Zeeman Effect in Planetary Atmospheric Radiative Transfer

    Författare :Richard Larsson; Bernd Funke; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmosfärsvetenskap; Atmospheric Science; Rymdteknik; Space Technology;

    Sammanfattning : There are special effects in spectroscopy that must be considered in order to fullyexplain how molecular oxygen interacts with radiation in planetary atmospheres.One of these, the Zeeman effect, is described in this thesis. LÄS MER

  5. 4. Zeeman Interaction in Low-Dimensional III-V Semiconductor Structures

    Författare :Bernhard Kowalski; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optically detected spin resonance; spin resonance; effective g-value; III-V semiconductors; low-dimensional structures; quantum wells; quantum dots; Stranski-Krastanow; photoluminescence; GaInAs; single dot Magneto-luminescence; Fysicumarkivet A:1997:Kowalski; Halvledarfysik; Semiconductory physics; GaInAs-InP;

    Sammanfattning : The Zeeman interaction in low-dimensional III-V semiconductor nanostructures is studied. The effective g-value of bulk InGaAs is measured by two different spin resonance techniques. Experimental conditions were found to control the Overhauser effect, thus enabling a highly accurate determination of the g-value, g* = -4.070 ± 0. LÄS MER

  7. 5. Modeling the Zeeman Effect in Planetary Radiative Transfer and Applications

    Författare :Richard Larsson; Juan R. Pardo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmosfärsvetenskap; Atmospheric Science;

    Sammanfattning : Remote sensing is about retrieving distant physical properties from locally observed radiation. The first step to remote sensing is to describe, or model, the radiative transfer. LÄS MER
