1. 6. Cenozoic landscape evolution in northern Sweden : Geomorphological interpretation within a GIS-framework

   Författare :Karin Ebert; Clas Hättestrand; Paul Bishop; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Long-term geomorphology; northern Sweden; base-level surface; inselbergs; digital elevation models; field observations; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

   Sammanfattning : The large-scale bedrock landscape in northern Sweden has a complex evolution history of planation, uplift, transgression, burial, weathering, and erosion. The aim of this thesis is to examine the long-term development of the area. Terms for base-level surfaces in the area are defined. LÄS MER

3. 7. Holocene climate and atmospheric circulation changes in northern Fennoscandia : Interpretations from lacustrine oxygen isotope records

   Författare :Christina E. Jonsson; Gunhild Rosqvist; Jan Seibert; Philip Barker; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oxygen isotope; diatom silica; lake sediment; atmospheric circulation; North Atlantic Oscillation; northern Fennoscandia; The Holocene; Little Ice Age; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

   Sammanfattning : This thesis investigates how variations in the oxygen isotopic composition of lake waters in northern Fennoscandia are recorded in lake sediment archives, especially diatoms, and how these variations can be used to infer past changes in climate and atmospheric circulation. Results from analyses of the oxygen isotopic composition of lake water samples (δ18Olakew) collected between 2001 and 2006 show that δ18O of northern Fennoscandian lakes is mainly controlled by the isotopic composition of the precipitation (δ18Op).

4. 8. Molecular Modeling of Cardiolipin

   Författare :Martin Dahlberg; Arnold Maliniak; Richard W. Pastor; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; fysikalisk kemi; Physical Chemistry;

   Sammanfattning : Biological membranes are assembled from many different lipids. Our understanding of membrane function and morphology is dependent on linking the properties of the lipids to the properties of the membranes. LÄS MER

5. 9. Cross-scale perspectives on heterogeneity in Swedish boreal forests

   Författare :Sofia Eriksson; Monica Hammer; Helle Skånes; Risto Kalliola; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sustainable forest management; biodiversity conservation; landscape analysis; historical maps; ownership; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Geography; Physical Geography;

   Sammanfattning : Maintaining species diversity, ecosystem functioning, and socioeconomic values requires continued ecosystem heterogeneity across scales. This thesis aims to bridge gaps between ecological theory, environmental goals, and practical application of sustainable forest management needed to maintain such heterogeneity. LÄS MER

7. 10. Health for future : self-rated health and social status among adolescents

   Författare :Junia Joffer; Lars Jerdén; Reneé Flacking; Ann Öhman; Anna Sarkadi; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescent; health; self-rated health; smoking; self-esteem; social status; subjective social status; gender; social norms; think-aloud interview; Public health; folkhälsa;

   Sammanfattning : The overall aim of this thesis was to explore self-rated health, subjective social status and smoking in adolescents.This thesis consists of a qualitative and a quantitative study. The qualitative study was an interview study that included 58 participants in the 7th and 12th grades. LÄS MER
