  2. 11. Cardiovascular modelling and ultrasound heart flow quantification : aortic flow and mitral regurgitation

    Author : Lars E. J. Eidenvall; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The primary objective of this thesis was to model and simulate aortic flow and mitral regurgitation and to improve quantitative ultrasound measurements. The tools used were; theoretical analysis, computer simulation, model experiments, image analysis and clinical evaluation. READ MORE

  4. 12. Systems Analysis of Chemicals Production via Integrated Entrained Flow Biomass Gasification : Quantification and improvement of techno-economic performance

    Author : Jim Andersson; Eric D. Larson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Lignocellulosic biomass gasification is a promising production pathway for green chemicals, which can support the development towards a more sustainable society where fossil fuels are replaced. To be able to compete with fossil fuels, a highly efficient production of biomassbased products is required in order to maximize overall process economics and to minimizenegative environmental impact.

  5. 13. Fractional moving blood volume in fetal organs estimated using power Doppler ultrasound

    Author : Edgar Hernandez-Andrade; Lund Obstetrik och gynekologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; andrology; gynaecology; Obstetrics; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; fetal adrenal gland; fetal lung; radionuclear microspheres; fetal lamb; perfusion; fetus; Power Doppler ultrasound; fractional moving blood volume;

    Abstract : Power Doppler ultrasound (PDU) is a sensitive technique to detect slow blood movement. The aim of the present study was to develop a standardized method for quantification of the PDU signals recorded from a specific region of interest (ROI) within fetal organs. READ MORE

  6. 14. Large Volume Injection and Hyphenated Techniques for Gas Chromatographic Determination of PBDEs and Carbazoles in Air

    Author : Petter Tollbäck; Conny Östman; Tuulia Hyötyläinen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; large volume injection; hyphenated techniques; LC-GC; GC-MS; mass spectrometry; GC; gas chromatography; carbazoles; PBDE; polybrominated diphenyl ethers; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis is based on studies in which the suitability of various gas chromatography (GC) injection techniques was examined for the determination of polybrominated diphenyl ethers (PBDEs) and carbazoles, two groups of compounds that are thermally labile and/or have high boiling-points. For such substances, it is essential to introduce the samples into the GC system in an appropriate way to avoid degradation and other potential problems. READ MORE

  7. 15. Invasive and Non-Invasive Quantification of Cardiac Kinematics

    Author : Katarina Kindberg; Matts Karlsson; Bjørn Skallerud; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The ability to measure and quantify myocardial motion and deformation provides a useful tool to assist in the diagnosis, prognosis and management of heart disease. Myocardial motion can be measured by means of several different types of data acquisition. READ MORE
