  1. 1. Röekillorna unsealed – an osteological analysis of the seal remains at Röekillorna Spring

    Kandidat-uppsats, Lunds universitet/Historisk osteologi

    Författare :Tea Jahrehorn Önnerfors; [2023]
    Nyckelord :zooarchaeology; osteological research; offerings-and burial; pinnipedia; grey seals; Neolithic; Iron Age; wetlands; pre-historical Scania; Baltic Sea; Röekillorna Spring; History and Archaeology;

    Sammanfattning : Zooarchaeological studies have played a crucial role in understanding the pre-historic societies of Scania. The analysis of animal remains from archaeological sites has provided insights into the subsistence strategies, economic practices, and cultural beliefs of the people who lived in the region.

    Nyckelord :water; wastewater; source separation; greywater; phosphorous; precipitation; utfällning; Chemical Engineering; Technology and Engineering;

    Sammanfattning : As our understanding of the impact humans have on the environment changes, so too do the mitigation strategies we employ to prevent it. One major source of anthropogenic pollution is wastewater effluent. LÄS MER

  5. 4. Variations in material properties of grey cast iron and its impact on tool wear

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell Produktion

    Författare :Andreas Söderholm; [2021]
    Nyckelord :Grey cast iron; hard inclusions; tool wear; machinability; graphite structure.; Technology and Engineering;

    Sammanfattning : Among cast materials, grey cast iron and ductile iron makes up about three quarters of all cast parts. This makes the manufacturing and machining of grey cast iron an important economical factor for the automotive industry. LÄS MER

  7. 5. INFLUENCE OF CARBON CONTENT AND COOLING CONDITIONS ON THE THERMAL CONDUCTIVITY AND TENSILE STRENGTH OF HIGH SILICON LAMELLAR GRAPHITE IRON

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Gokul Ram; Vishnu Harikrishnan; [2020]
    Nyckelord :Lamellar cast iron; hypereutectic; eutectic; hypoeutectic; carbon; silicon; carbon equivalent; cooling rate; dendrites; graphite flakes; specific heat capacity; thermal expansion coefficient; thermal diffusivity; thermal conductivity; tensile strength; hydraulic diameter.;

    Sammanfattning : Much study has been carried out to determine the properties of Lamellar Graphite Iron (LGI) or grey iron and their relations to factors such as the cooling rate, the dendrite morphology, the pouring temperature, and so on. However, there hasn’t been much comprehensive study on the properties of LGI outside the generally used and accepted composition, with 1 to 3% Silicon. LÄS MER
