  1. 6. Tankar kring Torsk : Isotopanalyser av torskkotor för att undersöka vikten av torskimport i medeltida Sverige

    Kandidat-uppsats, Stockholms universitet/Arkeologiska forskningslaboratoriet

    Författare :Beatrice Krooks; [2013]
    Nyckelord :torsk; isotopanalys; medeltid;

    Sammanfattning : This essay discusses the import of cod (Gadus morhua) in Sweden during the Middle Ages through isotope analysis of cod vertebrae. The isotope analysis is used to trace the cods origin to either the Baltic Sea or the Atlantic Ocean. The bones were subjected to d13C, d15N and d34S analysis; 64 of  the analyzed bones met the quality criteria. LÄS MER

  2. 7. Dödsrikets livshistorier : Benkemiska isotopanalyser på artikulerade och disartikulerade individer i Frälsegårdens gånggrift

    Sammanfattning : The aim in this thesis is to use carbon, nitrogen and sulfur isotope analysis on teeth and bone to track diet and mobility of the population as well as the individual level from the articulated and disarticulated individuals from the passage grave Frälsegården, situated in Gökhem parish in the region of Falbygden, western Sweden.50 human samples were analyzed from tooth, mandibula and femur, together with 11 faunal samples from different bone elements of local wild and domestic animals.

    Nyckelord :Gotland; church; grave; isotope ratio analysis; skeleton; bone; mediaeval; Visby; medeltid; Visby; Gotland; kyrka; grav; isotopanalys; skelett; ben;

    Sammanfattning : This paper deals with three mediaeval churches in the town Visby, Gotland. These churches were located in different areas in Visby. Allegedly the areas where St Hans and Ste Gertrud were located were inhabited by wealthier people, and the more peripheral area where St Mikael was located was where the poor lived. LÄS MER

  4. 9. Identifying possible sources of ammonium ions and arsenic in groundwater in the Nam Du area, Vietnam

    L3-uppsats, SLU/Dept. of Soil Sciences

    Författare :Peter Harms-Ringdahl; [2007]
    Nyckelord :groundwater; contamination sources; ammonium ions; arsenic species; redox potential; stable isotopes; Hanoi; Vietnam;

    Sammanfattning : Concentrations of arsenic and ammonium ions well above drinking water standards have been detected in aquifers which supply Hanoi, the capital of Vietnam, with fresh water. Chemical analyses showed arsenic and ammonium ion concentrations varying between 27 – 264 μg/l in freshwater and 1.8 – 34.7 mg/l in groundwater. LÄS MER
