2. 1. Metals take flight : Transport and effects across ecosystems

   Author : Johan Lidman; A. M. M. Berglund; Micael Jonsson; Christian Bigler; Brendan Mckie; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metals; aquatic subsidies; passerines; aquatic insects; environmental science; miljövetenskap; ekotoxikologi; Ecotoxicology;

   Abstract : Metal contamination can have severe toxic effects in the ecosystems, resulting in loss of biodiversity, reduced abundance of organisms, and loss of ecosystem services. Traditionally, aquatic ecosystems have been regarded as a sink of metal contamination. READ MORE

4. 2. Pulsed laser deposition and nanofabrication of mesoscopic devices based on cuprates and manganites

   Author : Roberto de Andrés Prada; Vladimir M. Krasnov; Christian Bernhard; Taras Golod; Dag Winkler; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cuprates; manganites; pulsed laser deposition; nano-fabrication; heterostructures; fysik; Physics;

   Abstract : This thesis explores the growth, the nano-fabrication and the study of the magneto-transport properties of Superconductor/Ferromagnet/Superconductor (SFS) structures from complex oxides such as the high Tc superconducting cuprate YBa2Cu3O7 (YBCO) and the ferromagnetic manganites La2/3Ca1/3MnO3 and La2/3Sr1/3MnO3 (LCMO and LSMO), deposited with the pulsed laser deposition (PLD) technique.The present work has been possible thanks to the collaboration between the “Magnetism and Superconductivity” Group at the University of Fribourg, in Switzerland, and the “Experimentell Kondenserade Materiens Fysik” Group at Stockholm University, in Sweden.

5. 3. Upper middle Cambrian through Furongian of Scandinavia with focus on trilobites, paleoenvironments and correlations

   Author : Fredrik Terfelt; Berggrundsgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Paleontologi; Palaeontology; Scandinavia; Paleoenvironments; Biostratigraphy; Trilobites; Cambrian; Furongian;

   Abstract : This thesis is based on studies of upper middle Cambrian through Furongian strata in Scandinavia with focus on trilobite biostratigraphy, taxonomy, paleoecology, and intercontinental correlation. The material studied derives mainly from Västergötland and Scania, southern Sweden. READ MORE

6. 4. Conodont biostratigraphy, taxonomy and palaeoecology in the Darriwilian (Middle Ordovician) of Baltoscandia - with focus on meteorite and extraterrestrial chromite-rich strata

   Author : Johanna Mellgren; Berggrundsgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conodonts; biostratigraphy; taxonomy; palaeoecology; morphometrics; extraterrestrial chromite; meteorites; Darriwilian; Middle Ordovician; Baltoscandia;

   Abstract : This thesis deals with conodont biostratigraphy and palaeoecology in the Darriwilian (Middle Ordovician) of Baltoscandia, with focus on limestone strata showing traces of the ~ 470 Ma L-chondrite parent body break-up. The evidence for this cosmic event includes abundant centimeter to decimeter-sized fossil meteorites and elevated levels of sediment-dispersed extraterrestrial L-type chromite found in a stratigraphical interval corresponding to the uppermost Lenodus antivariabilis, the L.
