  2. 6. The Common Thread, Textile Production during the Late Iron Age and Viking Age

    Author : Eva Andersson; Arkeologi; []
    Keywords : HUMANIORA; HUMANITIES; Haithabu; Birka; Scania; Viking Age; Late Iron Age; household production; textile valuables; sail cloth; bone needle; loom weight; textile production; spindle whorl; Archaeology; Arkeologi;

    Abstract : The initial aim of the present PhD thesis was to develop the method of classification for textile tools to facilitate the study of textile production in an archaeological context. The thesis consists of five separate projects and a concluding summary. The study covers the late Iron Age, mainly the Viking Period. READ MORE

  4. 7. Sustainable Aluminum and Iron Production

    Author : Reza Beheshti; Emma Strömberg; Jafar Safarian; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Optimization; Black Dross; Salt removal; Steel flux agent; Waste processing; Greenhouse gases; Direct reduction; COMSOL Multiphysics®; Kemi; Chemistry;

    Abstract : Aluminium recycling requires 95% less energy than primary production with no loss of quality. The Black Dross (BD) produced during secondary aluminium production contains high amounts of water-soluble compounds, therefore it is considered as a toxic waste. READ MORE

  5. 8. Outlanders? : Resource colonisation, raw material exploitation and networks in Middle Iron Age Sweden

    Author : Andreas Hennius; Neil Price; Karl-Johan Lindholm; James Barrett; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; outlands; non-agrarian production; resource exploitation; Scandinavia; Iron Age archaeology; pre-viking age; Vendel period; Viking Age; tar production; pitfall hunting; whaling; seasonal production sites; Inmark; Utmark; järnålder; arkeologi; ickeagrar produktion; resursexploatering; Archaeology; Arkeologi;

    Abstract : The Middle Iron Age, around 300–650 CE, was characterised by extensive transformations across many aspects of society in the area of present-day Sweden. Within the central agricultural regions of the southern parts of the country, these changes are evident in a re-organisation of the settlements, renewed burial practices, the building of large-scale monuments, as well as increased militarisation, social stratification and an increase in imported objects.

  6. 9. Competitive strength in iron ore production

    Author : Stefan Hellmer; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : This thesis is about competitive strength in the global markets for iron ore. Its focus is on the Swedish iron ore producer, LKAB, and its role in this global market. The finding of new vast deposits of iron ore in Brazil and Australia, together with falling transportation costs, meant that LKAB started to meet fierce competition in the 1970s. READ MORE

  7. 10. Biomimetic Iron Complexes involved in Oxygenation and Chlorination : A Theoretical Study

    Author : Holger Noack; Margareta R. A. Blomberg; Per E. M. Siegbahn; Martin Kaupp; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biomimetic; iron; density functional theory; intradiol; chlorination; adpic acid; diamond core; reactivity; Bio-inorganic chemistry; Bio-oorganisk kemi; Theoretical chemistry; Teoretisk kemi; kemisk fysik; Chemical Physics;

    Abstract : Biomimetic chemistry is directed towards the simulation of enzymatic reactivity with synthetic analogues. In this thesis a quantum chemical method has been employed to study the mechanism of highly reactive iron-oxo complexes involved in oxygenation and chlorination of organic substrates. READ MORE
