    Sammanfattning : The aim of this thesis was to evaluate cervical physiological changes by three-dimensional (3D) ultrasound during pregnancy and to investigate the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy. The thesis is based on five studies: reproducibility of cervical measurements by 3D power Doppler ultrasound (study I), reference data representative normal findings of the cervix assessed by 3D ultrasound during pregnancy (studies II, III) and the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy.

  3. 7. Computerised Three-Dimensional Analysis of Optic Nerve Head Topography in Normal and Glaucomatous Eyes

    Författare :Kjell Gunnar Gundersen; Oftalmologi (Malmö); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ranked segment distribution; minimal rim width; sector analysis; neuroretinal rim; global parameters; localised changes; computerised analysis; raster tomography; Optic nerve head topography; scanning laser tomography; Ophtalmology; Oftalmologi;

    Sammanfattning : Evaluation of the optic nerve head topography is one of the most important methods to diagnose and monitor patients with glaucoma. Until recently, optic nerve head topography has most often been judged by either ophthalmoscopy or from optic disc photographs. LÄS MER

  4. 8. Three Dimensional Hydro-Morphological Modeling of Tigris River

    Författare :Ammar Ali; Robert William Duck; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The River Tigris is a major river in Iraq. It divides Baghdad, the capital of Iraq, in two parts. The reach of the river within Baghdad is about 60 km long. The climate change within the region and the construction of hydraulic structures upstream of Baghdad has reduced the water discharge of the river by 44%. LÄS MER

  5. 9. Colour changes and acid formation in wood during heating

    Författare :Bror Sundqvist; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Sammanfattning : Heating wood has since ancient times been a method to dry and modify its properties. Nowadays heat is used in industrial processes for the same reasons. Treatment at temperatures above 150ºC can change the colour, improve resistance to biodegradation and enhance dimensional stability. LÄS MER

  7. 10. Microscopic Modeling of Exciton-Polaritons in Two-Dimensional Materials

    Författare :Beatriz Ferreira; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; exciton-polaritons; 2D materials; diffusion; absorption;

    Sammanfattning : Integrating 2D materials into high-quality optical microcavities opens the door to fascinating many-particle phenomena including the formation of exciton-polaritons. These are hybrid quasi-particles inheriting properties of both the constituent photons and excitons. LÄS MER
