  1. 11. Compacted graphite iron : On solidification phenomena related to shrinkage defects

    Författare :Björn Domeij; Attila Diószegi; Babette Tonn; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted graphite iron; Spheroidal graphite iron; Solidification; Microsegregation; Porosity; Kompaktgrafitjärn; segjärn; stelning; mikrosegregation; porositet;

    Sammanfattning : An improved understanding of solidification of compacted graphite iron (CGI) is necessary to predict shrinkage related casting defects. Spheroidal graphite is not only found in ductile iron (SGI) but usually also in CGI, but its characteristics and role in this material is less understood. LÄS MER

  3. 12. Iron absorption and iron status related to diet : an experimental and epidemiological study

    Författare :Per Tidehag; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; iron status; iron absorption; bioavailability; dietary fiber; phytate; calcium; radioiron; diet;

    Sammanfattning : The absorption of iron from the diet is a major determinant of the iron status of an individual. Accurate measures of iron absorption are thus essential in the determination of the effects of diet composition on iron absorption and status. LÄS MER

  4. 13. IRON NUTRITION DURING EARLY CHILDHOOD. Factors influencing iron status and iron intake

    Författare :Ann-Cathrine Bramhagen; Preventiv pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; feeding situation; Medicine human and vertebrates ; Pediatrics; Medicin människa och djur ; iron deficiency; Pediatri; maternal experinces; influencing factors; iron intake; child*;

    Sammanfattning : The overall aim of this thesis was to describe the prevalence of iron deficiency (ID) and factors influencing iron status and iron intake among otherwise healthy children. The specific aim in paper I+II was to describe the prevalence of ID among 2 ½-year-old children in relation to intake of cow's milk and follow-on formula. LÄS MER

  5. 14. Där människor, handling och tid möts : En studie av det förromerska landskapet på Gotland

    Författare :Anna Arnberg; Kerstin Cassel; Anders Kaliff; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Gotland; pre-Roman Iron Age; landscape; fossil field systems; agriculture; settlements; iron; iron-making; ring-forts; burials; burial grounds; burial customs; Archaeology; Arkeologi; arkeologi; Archaeology;

    Sammanfattning : This thesis is concerned with the pre-Roman Iron Age on Gotland (500 BC–AD). The remains studied comprise artefacts, fossil field systems, ring-forts, burial localities, and places for iron-making, and more. The author focuses on the landscape formed by these remains, in an attempt to understand the people and society behind them. LÄS MER

  7. 15. Drivers of increasing iron concentrations in freshwaters

    Författare :Caroline Björnerås; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Järn; Akvatisk ekologi; Biogeokemi; Brunifiering; Iron; Freshwaters; Biogeochemistry; Brownification; Iron biogeochemistry; Browning; Freshwaters;

    Sammanfattning : Iron (Fe) concentrations are increasing in freshwaters (lakes and streams) in Sweden, as well as in other regions in northern Europe. Together with increasing concentrations of organic matter, Fe is contributing to the ongoing browning of freshwaters, which may have serious ecological consequences and implications for ecosystem services.
