  1. 1. Mass Loss of Evolved Stars : Improving Mass-Loss Rates and Distances

    Författare :Miora Andriantsaralaza; Paul Barklem; Elvire De Beck; Susanne Höfner; Jacco van Loon; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AGB stars; Mass loss; Distance; Circumstellar matter; Radio interferometry; Stellar evolution; Fysik med inriktning mot astrofysik; Physics with specialization in Astrophysics;

    Sammanfattning : In the final stages of their lives, low to intermediate-mass stars enter the Asymptotic Giant Branch (AGB) phase, where they experience significant mass loss through dusty stellar winds. This mass loss is pivotal, not only for the chemical enrichment of the interstellar medium, setting the stage for new stars and planets to form, but also in dictating the evolution and the ultimate fate of the stars themselves.

  3. 2. Transmission loss of vehicle seals

    Författare :Qi Li; Leping Feng; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle seals; reverberation room test; contact analysis; simple model; mass law; FEM analysis; distorted circular duct model; Acoustics; Akustik;

    Sammanfattning : Sound transmission loss of vehicle seals was studied in this thesis. Reverberation room test and semi-anechoic chamber test were respectively studied. LÄS MER

  4. 3. Genetic studies of two inherited human phenotypes : Hearing loss and monoamine oxidase activity

    Författare :Jorune Balciuniene; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; linkage analysis; hearing loss; digenic inheritance; allelic association; monoamine oxidase; human genetic diversity; Genetik; Clinical genetics; Klinisk genetik; Medical Genetics; medicinsk genetik;

    Sammanfattning : This thesis focuses on the identification of genetic factors underlying two inherited human phenotypes: hearing loss and monoamine oxidase activity. Non-syndromic hearing loss segregating in a Swedish family was tested for linkage to 13 previously reported candidate loci for hearing disabilities. LÄS MER

  5. 4. Benthic diatoms in the Gulf of Bothnia : Community analysis and diversity

    Författare :Svenja Busse; Michael Sullivan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Baltic Sea; Biodiversity; Biomass; Community ecology; Diatoms; Multivariate analysis; Navicula; Phytobenthos; Salinity gradient; Scale; Size; Water movement; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Ecological Botany; Ekologisk botanik;

    Sammanfattning : Benthic diatoms are valuable tools for biological monitoring and paleo-ecological reconstruction of past environmental conditions. This thesis aims at describing size-related properties of benthic diatoms and suggests that data assessment for community analysis can be improved by considering the importance of scale. LÄS MER

  7. 5. I vinst och förlust : Köpmäns nätverk i 1500-talets Östersjöstäder

    Författare :Lovisa Olsson; Martin Wottle; Thomas Småberg; Dag Lindström; Södertörns högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; Trade; Early modern history; Baltic Sea region; Credit networks; Urban history; Embedded economy; Network analysis; Town councils; Spatiality; Mobility; Economic history; Handel; Tidigmodern historia; Östersjöregionen; Kreditnätverk; Urbanhistoria; Inbäddad ekonomi; Nätverksanalys; Städernas råd; Spatialitet; Mobilitet; Ekonomisk historia; Historical Studies; Historiska studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : This thesis aims to clarify how the merchant networks involved in the trade across the Baltic Sea interplayed with and contributed to create the economic culture of the Baltic Sea region. This is achieved by examining the economic, social, spatial and political aspects of the trade networks in relation to the social organisation of the early modern towns of Stockholm, Lübeck, Malmö and Reval (Tallinn) in the 16th century.
