2. 1. Consuming and communicating identities : Dietary diversity and interaction in Middle Neolithic Sweden

   Author : Elin Fornander; Kerstin Lidén; Per Andersson; Liv Nilsson Stutz; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Middle Neolithic; Neolithisation; Sweden; Baltic Sea; Funnel Beaker Culture; Pitted Ware Culture; Battle Axe Culture; megaliths; isotopes; δ13C; δ15N; δ34S; 87Sr 86Sr; radiocarbon dating; palaeodiet; mobility; interaction; identity; ethnicity; Archaeology; Arkeologi; Archaeological Science; laborativ arkeologi;

   Abstract : Isotope analyses on human and faunal skeletal remains from different Swedish Neolithic archaeological contexts are here applied as a means to reconstruct dietary strategies and mobility patterns. The chronological emphasis is on the Middle Neolithic period, and radiocarbon dating constitutes another central focus. READ MORE

4. 2. Stable and radiogenic isotopes as tracers for geochemical processes in mineralogically-complex mine waste environments : Insights from 13C, 2H, 18O, 34S and 87Sr/86Sr

   Author : Musah Salifu; Lena Alakangas; Maria Nieves Otero Perez; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geokemi; Applied Geochemistry;

   Abstract : Mining and its related activities generate large volumes of mine wastes such as tailings that can have negative environmental implications. One of such mine wastes of potential environmental concern is the historical Yxsjöberg Cu-W-F skarn tailings in Sweden, which encompasses a complex mineralogy including sulphides, carbonates, silicates, oxides / wolframite and halides.

5. 3. Our Bones, who art contaminated : Glues, strontium isotopes, and mobility in early Swedish Christians

   Author : Crista Adelle Wathen; Kerstin Lidén; Sven Isaksson; Christophe Snoeck; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Strontium isotopes; contamination; conservation; glues; Christianity; mobility; early Christians; Sweden; Varnhem; Västerhus; bones; teeth; Scientific Archaeology; arkeologi med inriktning mot laborativ arkeologi;

   Abstract : This thesis aims to build upon previous research into contamination and its effects on isotopes by focusing on the strontium isotopic ratio (87Sr/86Sr), which is used in mobility studies to study the movements of past humans and animals and to build past economic trading networks. Contamination is a broad topic, and in the scope of this thesis, it concerns the introduction of contaminants from the soil after interment and the post-excavation preservation efforts. READ MORE

6. 4. Provenance, transport, and the fate of organic matter and sediments drained through Himalayan Rivers in Nepal

   Author : Rajendra Bhandari; Joyanto Routh; Subodh Sharma; Åsa Danielsson; Rajendra Joshi; Mead Allison; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Himalayan rivers; Biomarkers; Isotopes; OC flux; RUSLE; Himalayafloder; biomarkörer; isotoper; OC flux; RUSLE;

   Abstract : Despite its small area (ca. 595,000 km2), the Himalayan region transfers disproportionally high amounts of sediments and organic matter (OM) through a network of rivers into the oceanic sink. READ MORE

7. 5. Tracking environmental changes of the Baltic Sea coastal zone since mid-Holocene

   Author : Wenxin Ning; Centrum för miljö- och klimatvetenskap (CEC); []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In this thesis, I used two coastal sediment sequences from SE Sweden to study how Baltic Sea coastal environment has changed since the mid-Holocene. The results show the coastal environment has been influenced by multi-stressors, such as climate change, shoreline regression and anthropogenic activities. READ MORE
