  1. 16. The Victims at Sandby Borg : Tracing mobility and diet usingstrontium analyses

    Master-uppsats, Stockholms universitet/Arkeologiska forskningslaboratoriet

    Författare :Kerstin Calleberg; [2019]
    Nyckelord :87Sr 86Sr; strontium; migration; Sandby borg; Öland; massacre; teeth; Migration Period; Iron Age; Laser Ablation;

    Sammanfattning : Sandby borg, an Iron Age ringfort on Öland, Sweden has been and is still at the center of attention in media and archaeological research. The massacre uncovered at the site during recent years opens many doors for analyses on the Migration Period (c. 400-550 AD) Iron Age skeletal remains. LÄS MER

  3. 17. Pitting Corrosion Evaluation of Post-Weld Cleaning Methods for Stainless Steel Welds

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jimmy Holgersson; Klara Trydell; [2019]
    Nyckelord :;

    Sammanfattning : Welding stainless steel creates an oxide film, heat tint, on the surface and around the joint. It disrupts passivation and influence the corrosion resistance for the material. The result is often a decrease in pitting corrosion resistance for the joint and surrounding area. The heat tint is therefore commonly removed by post weld cleaning. LÄS MER

  4. 18. Zircon U-Pb constraints on the timing of Sveconorwegian migmatite formation in the Western and Median Segments of the Idefjorden terrane, SW Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Mimmi Ingered; [2019]
    Nyckelord :Sveconorwegian orogen; U-Pb; Zircon; Migmatite; Idefjorden terrane; Earth and Environmental Sciences;

    Sammanfattning : The Western and Median Segments of the Idefjorden terrane have been metamorphosed and migmatized during the Sveconorwegian orogeny (ca. 1 Ga), but the timing of these events between the two segments remains unclear. LÄS MER

  5. 19. Development of a Laboratory Test Method for Assessment of Crater Wear Volume on Inserts for Steel Turning

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Joakim Sandberg; [2019]
    Nyckelord :Crater wear; turning; focus variation; volume;

    Sammanfattning : This thesis project was carried out at Sandvik Coromant in Västberga, Sweden with the purpose of developing a new laboratory test method for volumetric assessment of crater wear on inserts for steel turning. The test method was developed with the Sandvik Coromant´s existing crater wear measurement method as a starting point. LÄS MER

  7. 20. Petrology of platinum-group element mineralization in the Koillismaa intrusion, Finland

    Master-uppsats, Lunds universitet/Geologiska institutionen
