  2. 1. Diastolic left ventricular filling in 50-year-old male and female adults : Evaluation by Doppler echocardiography

    Author : Toomas Kangro; Uppsala universitet; []
    Keywords : Medical sciences; Arterial distensibility; diastole; Doppler echocardiography; exercise; healthy persons; hypertension; LV filling; menopause; medicin; vård; MEDICINE; MEDICIN; Clinical Physiology; Klinisk fysiologi;

    Abstract : Left ventricular (LV) diastolic filling abnormalities are seen in many patients with various cardiac disorders. Age is an important determinant of Doppler indices of LV diastolic filling. READ MORE

  4. 2. Laser doppler tissue flowmetry : fiberoptic methods in microvascular research

    Author : Göran Salerud; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Laser Doppler flowmetry (LDF) constitutes a method for measuring the flux of blood cells in the microcirculatory bed. Photons are scattered in the moving blood cells, where they undergo a frequency shift according to the Doppler principle. READ MORE

  5. 3. Nuclear Dynamics in X-ray Absorption and Raman Scattering

    Author : Ivaylo Minkov; Faris Gelmukhanov; Knut Borve; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray scattering; theory; simulations; recoil; Doppler effect; nuclear dynamics; Auger; XPS; Theoretical chemistry; Teoretisk kemi;

    Abstract : This thesis presents theoretical studies of several x-ray spectroscopies - x-ray absorption, x-ray photoelectron emission, radiative and non-radiative resonant Raman scattering spectroscopy. The main focus point is investigating the influence of nuclear dynamics on these spectra for a variety of small molecules - naphthalene, biphenyl, ethylene, the water dimer, HCl, CO. READ MORE

  6. 4. Visible spectroscopic diagnostics : application and development in fusion plasmas

    Author : Sheena Menmuir; Professor Elisabeth Rachlew-Källne; Lorella Carraro; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; visible spectroscopy; fusion; Doppler shift; Doppler broadening; Plasma physics with fusion; Plasmafysik med fusion;

    Abstract : Diagnostic measurements play a vital role in experiments. Without them we would be in the dark with no way of knowing what was happening; of understanding the processes and behaviour occurring; or even of judging the success or failure of our experiments. The development of fusion plasma devices is no different. READ MORE

  7. 5. Quantum Nuclear Dynamics in Resonant X-ray Scattering of Gas-Phase and Liquid Systems

    Author : Vinicius Vaz da Cruz; Victor Kimberg; Faris Gel'mukhanov; Hans Ågren; Philippe Wernet; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resonant inelastic X-ray scattering; X-ray absorption; water; methanol; CO; rotational doppler effect; recoil; wave packet; non-Franck-Condon effect; ultra-fast molecular dissociation; potential energy surface; hydrogen bond; liquid; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : This thesis focuses on the role of the nuclear degrees of freedom in X-ray induced molecular processes. An important part of it is devoted to establishing theoretical principles to model and interpret high-resolution resonant X-ray scattering experiments in gases and liquids. READ MORE
