1. 11. Hazard screening of contaminated sites : bioavailable fractions and biological in vitro tools

   Författare :Daniel Ragnvaldsson; Mats Tysklind; Per Leffler; Lars Lövgren; Bengt-Erik Bengtsson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hazard screening; bioavailability; metal pollution; in vitro cytotoxicity; water extraction; CCA; arsenic genotoxicity; genotoxicity; Contaminated soil; Environmental chemistry; Miljökemi;

   Sammanfattning : The environmental bioavailability of contaminants, rather than their total concentrations in the soil compartment play a decisive role for the risks associated with contaminated sites. Various soil constituents and abiotic conditions have strong influence on bioavailability, which may vary substantially between different locations. LÄS MER

3. 12. Flexibilitetens gränser : Förändring och friktion i arbetsliv och familj

4. 13. Biodiversity in fragmented boreal forests : assessing the past, the present and the future

   Författare :Håkan Berglund; Bengt Gunnar Jonsson; Jari Kouki; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; bryophytes; CWD; edge effects; fragmentation; fungi; habitat destruction; historical records; indicator; lichens; regression; species-area relationship; value pyramids; woody debris; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

   Sammanfattning : The aims of this thesis are to (1) analyze the predictability (indicators) of plant and fungal species diversity in old-growth forests, and (2) assess the history and biodiversity of woodland key habitats (WKHs) and their potential to maintain species diversity in fragmented boreal forest landscapes. Predictability was explored in Granlandet nature reserve, an unexploited landscape composed of discrete old-growth Picea forest patches of varying size isolated by wetland, reflecting conditions of insular biota at stochastic equilibrium.

5. 14. Vinterbyar : ett bandsamhälles territorier i Norrlands inland, 4500-2500 f. Kr

   Författare :Åsa Lundberg; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; social territory; local band; regional band; language family; settlement pattern; semi-sedentary; late mesolithic; neolithic; semi-subterranean house; winter sites; red slate; pit-falls; cooking pits; scrapers;

   Sammanfattning : The main archaeological features studied in this thesis are semi-subterranean house remains in the woodlands of middle northern Sweden, east of the high mountains and some 100 km from the coast. The period during which they were occupied has been delimited to 4500-2500 BC. LÄS MER

7. 15. Pioneer Settlement in the Mesolithic of Northern Sweden

   Författare :Anders Olofsson; Noel Broadbent; Ingela Bergman; Bo Knarrström; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Mesolithic; pioneer settlement; lithic technology; cultural context; chronology; glacio-isostatic uplift; lake-tilting; Arkeologi; Archaeology subjects; Arkeologiämnen; Archaeology; arkeologi;

   Sammanfattning : The aim of the thesis is to cast light on the earliest settlement of northern Sweden. The starting point is lithic artifacts, which have been studied from a technological as well as a more conventional typological perspective (Papers I, II, and IV). LÄS MER
