16. Submarine slope instability as a cause of contaminated sediment dispersal in Ångermanälven, Sweden
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : This study aims at providing results for the analysis of the stratigraphy underlying contaminated sediments in Ångermanälven. The contaminated sediments, containing heavy metals and persistent organic pollutants, are derived from wastewater discharged into Ångermanälven from nearby paper and pulp industries. LÄS MER
17. Den ena boplatsvallen är den andra lik? : Miljöarkeologisk intra-site studie av boplatsvallar vid Lillsjön, Anundsjö sn., Ångermanland
Master-uppsats, Umeå universitet/Miljöarkeologiska laboratorietSammanfattning : Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as –embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden.

18. MRI-based quantification of cerebral oxygen extraction and oxygen metabolism using the relationship between phase shift and magnetic susceptibility
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Introduction: The main purpose of this study was to extract global values of oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen (CMRO2) in healthy volunteers, using magnetic resonance imaging (MRI) phase maps. The repeatability of the method was evaluated, and the age dependences of OEF and CMRO2 were analyzed. LÄS MER
19. Hörneborg - borg eller lada? : kolanalys, magnetisk susceptibilitet, sjösänkning och historiska kartor.
M1-uppsats, Högskolan KristianstadSammanfattning : Hörneborg ligger på en udde i sjön Hörnsjön i Olofströms kommun i Blekinge län. En utgrävning av borgen gjordes 1997 för att fastställa funktion och ålder. 14C dateringar visade att borgen var byggd cirka 1030-1250 e.Kr. LÄS MER
20. A multi-proxy study of a Holocene peat sequence on Nightingale Island, South Atlantic
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Nightingale Island is situated at 37°S in the central part of the South Atlantic Ocean, which is a sensitive location for variations within the Atlantic Meridional Overturning Circulation (AMOC) and the Southern Hemisphere Westerlies (SHW) wind belt. A peat sequence from the wetland 2nd Pond has been investigated with emphasis on the composition of the deposits, loss on ignition (LOI), total Carbon (TC), Nitrogen (N), biogenic Silica (BSi), magnetic susceptibility (MS), diatom counting and macrofossil analysis.
