  2. 2. Silicone Rubber Insulators: Impacts of Material Formulation in Coastal Environment

    Författare :Tomas G Gustavsson; Chalmers University of Technology; []
    Nyckelord :surface characterization; aging; filler level; outdoor insulation; leakage current measurements; material formulation; silicone rubber; polymeric insulators; coastal environment; polydimethylsiloxane PDMS ;

    Sammanfattning : This thesis deals with influences of material formulation on the performance of silicone rubber high voltage insulators in a coastal environment. Samples and insulators with known differences in material compositions have been used in this task. In the first step, a screening test with cylindrical samples was initiated. LÄS MER

  4. 4. Coastal Communities on the Move : House and Polity Interaction in Southern Ostrobothnia 1500 BC-AD 1

    Författare :Peter Holmblad; Karin Viklund; Henrik Asplund; Umeå universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Community archaeology; Settlement archaeology; Landscape archaeology; Environmental archaeology; House society; Local polity; Bronze Age; Pre-Roman Iron Age; Subsistence practices; Habitation practices; Political economy; Ostrobothnia; Finland; Archaeology; North European; Arkeologi; nordeuropeisk; Archaeology; arkeologi;

    Sammanfattning : This work attempts to seek new insights in understanding the archeological phenomena traditionally labelled as the western Bronze Age and the coastal Pre-Roman cultures of Finland (1500 BC-AD 1), by studying the phenomena from a socioeconomic interaction and practice oriented community perspective. The basic line of thought is that it was the everyday life of the local agents and their interactions that constituted the local communities. LÄS MER

  5. 5. Swedish seagrass ecosystems in a changing climate : Coastal connectivity and global change sensitivity

    Författare :Diana Perry; Martin Gullström; Jason Hall-Spencer; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; coastal seascape; shallow-water ecosystems; fish assemblages; connectivity; global change; climate change; multiple stressors; seagrass; Zostera marina; temperate region; marin ekologi; Marine Ecology;

    Sammanfattning : Coastal shallow-water ecosystems are essential for providing several goods and services globally, with seagrasses as an important contributor for maintaining high biodiversity and productivity within the nearshore seascape. The temperate species Zostera marina serves as a vital habitat for many species, including ecologically and economically important juvenile fish. LÄS MER
