  2. 1. The soil as a source material in archaeology. : Theoretical considerations and pragmatic applications

    Author : Johan Linderholm; Roger Engelmark; Martin Bell; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; Environmental archaeology; Geoarchaeology; Prehistory; Soil phosphate; Magnetic susceptibility; Soil chemistry; Site formation processes; Soil erosion; Archaeology subjects; Arkeologiämnen; Archaeology; arkeologi;

    Abstract : This thesis deals with questions on various applications using soils and sediments as sources of information in archaeological research. Human environmental impact on soils and sediments, in terms of pollution, is a well known phenomenon as the industrialisation intensified during historical times and onwards and has left strong pollutive marks.

  4. 2. Chemical-Looping Combustion with Natural Gas Using NiO-Based Oxygen Carriers

    Author : Carl Johan Linderholm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical-looping combustion; fluidized bed; CO2 capture; nickel oxide; oxygen carrier;

    Abstract : CO2 capture and storage has been proposed as an alternative to mitigate global warming. Chemical-looping combustion is an unmixed combustion concept where fuel and combustion air are kept separate by means of an oxygen carrier and the CO2 capture is inherently achieved. READ MORE

  5. 3. CO2 Capture using Chemical-Looping Combustion – Operational Experience with Gaseous and Solid Fuels

    Author : Carl Johan Linderholm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nickel oxide; coal; natural gas; chemical-looping combustion CLC ; oxygen carrier; CO2 capture; manganese ore; interconnected fluidized beds; ilmenite;

    Abstract : CO2 capture and storage has been proposed as an alternative to mitigate global warming. Chemical-looping combustion (CLC) is an unmixed combustion concept where fuel and combustion air are kept separate by means of an oxygen carrier, and the CO2 capture is inherently achieved.

  6. 4. Animating soils : geoarchaeological approaches to past human-environment relationships in the Arctic

    Author : Philip Jerand; Johan Linderholm; Philip I. Buckland; Carl-Gösta Ojala; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; environmental archaeology; sampling; Sámi archaeology; spatial organisation; Arctic archaeology; geoarchaeology; soil formation; historical archaeology; miljöarkeologi; provtagning; samisk arkeologi; rumslig organisering; Arktisk arkeologi; geoarkeologi; jordmånsbildning; historisk arkeologi; Archaeology; arkeologi; environmental archaeology; miljöarkeologi;

    Abstract : In this thesis, soils and sediments have been used as sources of information on past human activity in Arctic environments. The study has combined geoarchaeological methods and techniques with information from historical documents, ethnographic accounts, and archaeological remains to create integrated narratives of human-landscape interactions in the past.

  7. 5. Carved Mountains and Moving Stones : applications of Near Infrared Spectroscopy for Mineral Characterisation in Provenance Studies

    Author : Claudia Sciuto; Johan Linderholm; Paul Geladi; Rachel Opitz; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; Raw materials; mineral characterization; material agency; Near Infrared spectroscopy; hyperspectral imaging; Energy-Dispersive X-ray Fluorescence; multivariate statistics;

    Abstract : The study of stone artefacts is a combination of anthropological archaeology and geology, rooted in analytical techniques for determining the materials’ composition, typological stylistic classification and interpretation of cultural patterns. In this thesis, the archaeology of materials is considered in the context of sites- and landscape transformation, economic history and development of techniques. READ MORE
