  1. 11. Phosphorus Emissions from Fish Farms : Observed and Predicted Effects

    Författare :Torbjörn Johansson; Kurt Pettersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Fish farm; phosphorus; eutrophication; model; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

    Sammanfattning : During the last decades, fish farming has been a rapidly increasing industry in many European and North American countries. Sweden has a large potential for aquaculture, but there is also a strong concern about the effects on the environment that an increased aquaculture production may cause. LÄS MER

  2. 12. Predictive Models and Eutrophication Effects of Fish Farms

    Författare :Lennart Nordvarg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Fish farm; eutrophication; model; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

    Sammanfattning : Aquaculture has become one of the fastest growing food industries in the world. Like many other industries, aquaculture, and especially fish farms may cause negative effects on the environment, such as eutrophication, which is recognised as a major threat to aquatic ecosystems.

  3. 13. Changes, Activities and Bones : Intra-site analysis of the Pitted Ware Culture site Ajvide on the Baltic Sea island of Gotland

    Författare :Alexander Sjöstrand; Sabine Sten; Paul Wallin; Gustaf Svedjemo; Kristiina Mannermaa; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Osteology; GIS; Archaeology; Stone Age; Middle Neolithic; Pitted Ware Culture; Bourdieu; practice theory; Gotland; Ajvide; ritual.; Archaeology; Arkeologi;

    Sammanfattning : In this dissertation the structure, practices and evolution of a single Pitted Ware Culture site, Ajvide on Gotland, is explored and placed within the larger Pitted Ware Culture context. The site has been excavated over a period of 24 years, making it one of the most excavated Pitted Ware Culture sites in Sweden. LÄS MER

  4. 14. Bacterial Vaginosis : Diagnosis, Prevalence, and Treatment

    Författare :Katarina Eriksson; Per-Göran Larsson; Urban Forsum; Ann-Sofie Adolfsson; Inger Mattsby-Baltzer; Linköpings universitet; []
    Nyckelord :Bacterial vaginosis; prevalence; diagnosis; PAP-smear; probiotic treatment; clindamycin; MEDICINE; MEDICIN;

    Sammanfattning : Bacterial Vaginosis (BV) is a disorder of unknown etiology, characterized by a foul smelling vaginal discharge, loss or reduction of the normal vaginal Lactobacilli, and overgrowth of other anaerobic bacteria. Thus, it presents a formidable problem for clinicians as well as microbiologists researching its etiology, clinical course, treatment, and epidemiology. LÄS MER

  5. 15. Uncovering Ocean Mixing near Rough Bathymetry : Using Broadband Acoustics

    Författare :Julia C. Muchowski; Christian Stranne; Martin Jakobsson; Lars Umlauf; Lars Arneborg; Fer Ilker; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ocean mixing; diapycnal mixing; broadband acoustics; turbulence microstructure; rough bathymetry; stratified flow over obstacles; observations of turbulent mixing; Baltic Sea research; maringeologi; Marine Geology;

    Sammanfattning : Ocean mixing related to rough bathymetry is highly dynamic and exhibits large spatial and temporal variability. Therefore, established in-situ methods as well as numerical models often lack the resolution to capture this type of mixing. In this thesis, acoustics are used to observe, map and quantify stratified mixing at unprecedented resolution. LÄS MER
