  1. 16. Casting Identities in Central Seclusion : Aspects of non-ferrous metalworking and society on Gotland in the Early Medieval Period

    Författare :Ny Björn Gustafsson; Lena Holmquist; Heidemarie Eilbracht; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeometallurgy; Non-ferrous; Archaeological prospection; Metal detection; Geophysical survey; Sweden; Magnetometry; Gotland; Iron Age; Viking Period; Archaeological Science; laborativ arkeologi;

    Sammanfattning : The aim of this thesis has been to investigate and interpret late Iron Ageand Early Medieval traces of non-ferrous metalworking on the islandGotland, Sweden. Gotland was not, based on the archaeological record, anintegrated part of the common Scandinavian culture. LÄS MER

  3. 17. The Role of Microstructure in the Atmospheric Corrosion of Selected Light Alloys and Composites

    Författare :Mohsen Esmaily; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; galvanic corrosion; Al content; microstructure; intermetallic particles; atmospheric corrosion; Al alloy 6xxx; casting; Mg-Al alloys; FSW P; BFSW.; Mg alloys-based MMCs;

    Sammanfattning : Magnesium-aluminum (Mg-Al) alloys, Mg-based metal matrix composites (MMCs) and Al alloys are among the best material candidates for future lightweight solutions. However, the use of these materials is limited by a number of issues, including the ability to resist corrosion. LÄS MER

  4. 18. Structure Function Relationships in Pyrimidine Degrading and Biocatalytic Enzymes, and Their Implications for Cancer Therapy and Green Chemistry

    Författare :Dirk Maurer; Doreen Dobritzsch; Mikael Widersten; Rikkert Wierenga; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; β-Ureidopropionase; Dihydropyrimidine Dehydrogenase; Alcohol Dehydrogenase; Pyrimidine catabolism; 5-Fluorouracil; CASTing; X-ray Crystallography;

    Sammanfattning : This thesis includes the work of two separate projects, studies on pyrimidine degrading enzymes and studies on in vitro evolved enzymes. The common denominator of both projects was the use of structural information to explain functional effects, observed in the studied biocatalysts. LÄS MER

  5. 19. Tribological Aspects of Pneumatic Clutch Actuators

    Författare :Frida Riddar; Åsa Kassman Rudolphi; Roland Larsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear; friction; PTFE transfer; anodised aluminium; NBR rubber lip seal; silicone grease; casting; extrusion; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : A clutch actuator is used in a vehicle to transmit movement and force from the clutch pedal to the release bearing of the clutch. A pneumatic clutch actuator consists of an anodised aluminium cylinder, inside of which a piston, with a rubber lip seal and a PTFE guiding ring, slides. The system is lubricated with silicone grease before assembly. LÄS MER
