  2. 1. Early Pottery Use among Hunter-Gatherers around the Baltic Sea

    Author : Vasiliki Papakosta; Sven Isaksson; Ole Stilborg; Åsa Maria Larsson; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Early Pottery Use; Hunter-Gatherers; Baltic; Late Mesolithic; Ceramics; Ertebølle; Narva; Early Comb Ware; Lipid Extraction; Lipid Residue Analysis; Molecular Analysis; Stable Carbon Isotope Analysis; Elemental Analysis; Mineralogical Analysis; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

    Abstract : This thesis aims to provide an understanding of the dynamics underlying the adoption of pottery by pre-agrarian hunter-gatherer cultural groups around the Baltic Sea. The focus is on three approximately contemporaneous early pottery traditions of the region (ca. READ MORE

  4. 2. Studies of Tropospheric and Stratospheric Aerosol using Ion Beam Analysis

    Author : Giorgos Papaspiropoulos; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmosphere; Aerosols; troposphere; stratosphere; ion beam analysis; PIXE; impactors; particulate sulphur; chemical speciation; elemental analysis; thermography; Physics; Nuclear physics; Fysik; Metrology; Kärnfysik; physical instrumentation; Metrologi; fysisk instrumentering; Fysicumarkivet A:2001:Papaspiropoulos;

    Abstract : Atmospheric aerosol particles are believed to have an impact on the radiative forcing of the earth's surface. The predicted results indicate a net cooling effect on the global climate, however there are few studies available to substantiate this and experimental data are needed. READ MORE

    Abstract : This thesis describes two different sample preparation strategies for inductively coupled plasma atomic emission spectrometry (ICP-AES), and their ability regarding multi element quantification in complex samples. Sensitivity, repeatability, reproducibility and accuracy were investigated. READ MORE

  6. 4. Investigation of lithium and fluorine content in geological materials using Nuclear Reaction Analysis (NRA)

    Author : Nathaly de La Rosa; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nuclear reaction analysis NRA ; Geological material; Elemental composition analysis; Ion Beam Analysis IBA ;

    Abstract : This work focuses on the optimization of the Nuclear Reaction Analysis (NRA) technique to determine the content of lithium and fluorine in geological materials. Measuring low concentration of these isotopes is of great relevance in many fields such as geological, astrophysical, biological and material sciences. READ MORE

  7. 5. Food Cultures in Sápmi : An interdisciplinary approach to the study of the heterogeneous cultural landscape of northern Fennoscandia AD 600–1900

    Author : Markus Fjellström; Gunilla Eriksson; Kerstin Lidén; Lars Liedgren; Marianne Skandfer; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Food Culture; Diet; Mobility; Iron Age; Middle Ages; Sápmi; Sámi Archaeology; Reindeer Domestication; Stable Isotope Analysis; Elemental Analysis; Repatriation; Reburial; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

    Abstract : The aim of this thesis is to highlight the heterogeneous cultural landscape in Sápmi through the study of food. By studying food and the choices of specific foodstuffs in Sápmi AD 600–1900, a greater understanding can be gained on the history of this area during the period. READ MORE
