1. 1. Diatoms as indicators of Holocene climate and environmental change in northern Sweden

   Författare :Christian Bigler; Ingemar Renberg; Roland Hall; N. John Anderson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical geography and sedimentology; diatoms; Holocene; paleolimnology; climate change; lake sediments; transfer functions; quantitative environmental reconstructions; northern Sweden; Abisko; Naturgeografi och sedimentologi; Physical geography; Naturgeografi; naturgeografi; Physical Geography;

   Sammanfattning : The objective of the thesis was to explore the potential of diatoms (Bacillariophyceae) as indicators of Holocene climate and environmental change in northern Sweden (Abisko region, 68°21'N, 18°49'E). A modern surface-sediment calibration set including 100 lakes was developed and lake-water pH, sedimentary organic content (assessed by loss-on-ignition) and temperature were identified as most powerful environmental variables explaining the variance within the diatom assemblages.

   Sammanfattning : The aim of this thesis is to study the nation building process in Sweden. How was a national identity constructed? One answer to this question is that statistical representations of the nation played a major role to shape a visual image of Sweden. Statistical books became a popular genre during the nineteenth century. LÄS MER

4. 3. Electron transport in π-conjugated systems

   Författare :Magnus Paulsson; Libero Zuppiroli; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This thesis deals with theoretical studies of electron localization and conductance in conjugated molecular systems. Anderson localization of electrons is examined for nearly one-dimensional systems. This work was performed to understand the peculiar electronic properties of conducting polymers. LÄS MER
