Proveniensbestämning av vikingatida hornmaterial : En studie utifrån stabila isotoperSchyman, Joakim January 2012 (has links)
The main aim was to investigate the provenance of Viking age antler material findings of moose and red deer from Sigtuna and from three sites on the island of Gotland in the Baltic sea. This was done by analysis of the stable isotopes of carbon, nitrogen and sulphur. Thre were never any living population of these mammals on Gotland during the Viking age. δ34S-values of sulphur from this study was compared with earlier research and by studying maps of the Swedish bedrock. The δ34S-values were more like the δ34S-value for bedrock other than European granite. These bedrocks are found in the south-east of Sweden along the coast towards Gotland. The provenance of the Sigtuna antlers could be three different areas and the material from Gotnald could come from two differente regions. A student-t test between Fröjel and Sigtuna showed no significant correlation between the two populations. A comparison within the Sigtuna material showed a possible difference between two different dated phases. This could mean that an import of antlers from other areas was made when antlers in the Sigtuna region was less available.

Kan strålar av ljus tyda det förflutna? : Användning av Reflectance Transformation Imaging (RTI) för att tyda runinskrifter på Pireus-lejonetNazerian, Simon January 2014 (has links)
This paper deals with testing the method Reflectance Transformation Imaging (RTI) on the copy of the Piraeus-lion in Historic Museum in Stockholm. The purpose is to find out if it is possible to gather more information about the runic inscriptions. RTI is a method that records the surface normal of individual pixels in a digital photograph by analyzing the impact of light coming from different angles of entrance. RTI produces sort of a 3D-image of the object. There will be an overview of earlier interpretations of the runic scripts written on the lion as well as an overview of Varangians in the southeast. After examination of the lion with RTI, has a conclusion been made that the method should be performed again on similar items, and on the copy of the Piraeus-lion to evaluate its full potential.

Unwrapping the Past : A chemical analysis of context lacking artefacts from the Ptolemaic and Roman Egypt in correlation with the process of mummication.Pappas Adlerburg, Nickolas January 2013 (has links)
This paper deals with the chemical identification of artefacts correlated with the process of ancient Egyptian mummification dating to the Graeco-Roman period. The samples were harvested from two artefacts belonging to the Museum of Mediterranean and Near Eastern Antiquities in Stockholm. The original description of the said samples defined them, as natron filled linen bags and bee product (honey?). To identify the true nature of the samples, advanced methods such as Fourier transform infrared spectrometry (FTIR), gas chromatography/mass spectrometry and powder X-ray Diffractometry were used. The results were correlated with previous made analyses regarding embalming materials to discover similarities. Furthermore, the research revealed that the previous sample identifications were false, while providing hypotheses based on the new results.

Neolithic farmers in Poland - A study of stable isotopes in human bones and teeth from Kichary Nowe in the south of PolandLundmark, Staffan January 2016 (has links)
The diet of the Stone Age cultures is a strong indicator to the social group, thus farmers and hunters can be distinguished through their diet. There is well-preserved and well excavated Polish skeletal material available for such a study but the material has not previously been subject to stable isotopes analyses and therefore the questions of diets has not been answered. This study aims to contribute to the understanding of the cultures in the Kichary Nowe 2 area in the Lesser Poland district in southern Poland. Through analysis of the stable isotopes of Carbon, Nitrogen and Sulphur in the collagen of teeth and skeletal bones from the humans in the Kichary Nowe 2 grave-field and from bones from the fauna, coeval and from the same area, the study will establish whether there were any sharp changes of diets. The material from the grave-field comes from cultures with an established agricultural economy, where their cultural belonging has been anticipated from the burial context. The results from my study of stable isotopes from the bone material will be grouped by various parameters, culture, attribution to sex and age. The groups will then be compared to each other to investigate patterns within and between the groups.

To Make Iron of Iron : A Comprehensive Analytical Study of Spade Shaped Iron BarsPappas Adlerburg, Nickolas T. January 2017 (has links)
This thesis aims to provide adequate analytical information on the spade shaped iron bars of Norrland and central Sweden. While their significance has been thoroughly debated for decades, analytical research on them has been confined to cases of single artefacts or theoretical interpretations of their value, meaning and origin. In this study a comprehensive approach is taken into consideration. Based on X-Ray fluorescence (XRF), scanning electron microscopy (SEM) and metallographical analysis this thesis seeks to facilitate new interpretations on quality, production centres and usage based on analytical results. Aiming to settle some of the long lasting questions regarding the artefacts while producing results which can further the discussion by raising new questions, previously unasked.
