  1. 16. The effect of body position on the relative contribution of the rib cage to speech breathing and voice quality

    Kandidat-uppsats, Stockholms universitet/Avdelningen för fonetik

    Författare :Helena Engström; [2023]
    Nyckelord :Speech breathing; body position; voice quality; respiratory inductance plethysmography; accelerometer; Talandning; kroppsposition; röstkvalité; respiratory inductance plethysmography; accelerometer;

    Sammanfattning : This study investigates how body position affects the relative contribution of the rib cage to speech breathing and voice quality. The frequently used upright and supine body positions are expanded with the addition of an inverted position as a condition. LÄS MER

  3. 17. Sprickorna i Konstnärsförbundets styrelse

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Helena Berg; [2022-07-05]
    Nyckelord :oil painting; heritage science; non-destructive; tomography;

    Sammanfattning : All oil paintings do degrade with time and a clear sign of this ageing is the cracks seen at the surface of the painting. Cracks can , however, also be hidden underneath the very surface and in fact extend all the way down to the very substrate. LÄS MER

  4. 18. ASSESING HISTORICAL (1926-1996) NEAR-SURFACE WIND SPEED VARIABILITY ACROSS SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jessika Lönn; [2022-06-27]
    Nyckelord :Near-surface wind speed; teleconnection patterns; Sweden; stilling; reversal;

    Sammanfattning : Homogenized near-surface wind speed (NSWS) series of 7 stations from rescued observational journals have been analyzed for the 70-years time-period 1926-1996 to investigate past changes and variations across Sweden. During the whole period, there has been a statistically significant (at p < 0.05) decreasing trend of -0.11 m s-1 decades-1. LÄS MER

  5. 19. Flow modeling and bank erosion downstream due to spillway discharge : Independent thesis Advanced level (professional degree) 30 ECTS credits

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Alexander Lindblad; [2022]
    Nyckelord :Ansys Fluent; Multiphase Flow; Spillway; CFD; Volume of Fluid; Reynolds-averaged Navier-Stokes;

    Sammanfattning : Dam spillways and downstream areas are used to guide large flows of water during for example heavy rainfall. The large flows give way to turbulent pattern sand velocities that may damage the river banks or the dam structure. Investigation of these water patterns at certain flows are therefore done to examine at risk areas. LÄS MER

  7. 20. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Nsioh Elvis Nkioh; [2022]
    Nyckelord :geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

    Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER
