1. 6. Evolution and taxonomy of Cambrian arthropods from Greenland and Sweden

   Författare :Martin Stein; John S. Peel; Dieter Waloszek; David J. Siveter; Reinhardt M. Kristensen; David L. Bruton; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cambrian; Arthropods; Trilobites; Evolution; Greenland; Sweden; Historical geology and palaeontology; Historisk geologi och paleontologi;

   Sammanfattning : Arthropods have a rich fossil record spanning the Phanerozoic. Biomineralized forms such as the extinct trilobites are particularly common and are proven index fossils for biostratigraphy. Forms with an unmineralized cuticle are more rare, preserved only in so called konservat lagerstätten. LÄS MER

4. 8. Some Mathematical Aspects of Thermo and Fluid Dynamics

   Författare :Carl Fredrik Stein; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; swirling jets; vortex breakdown; conical self-similarity; Long s jet; Taylor s hypothesis; frozen turbulence hypothesis; advection velocity; conjugate heat transfer; asymptotic analysis; swirling jets;

   Sammanfattning : This thesis contains mathematical treatments of three issues in thermo and fluid dynamics: swirling jets and vortex breakdown, Taylor's hypothesis and conjugate heat transfer. The work on swirling jets is focused on the study of the well-posedness of the conically self-similar free-vortex solutions to the Navier--Stokes equations. LÄS MER

5. 9. The Emergence of the Post-Socialist Welfare State - The Case of the Baltic States : Estonia, Latvia and Lithuania

   Författare :Jolanta Aidukaite; Sven Hort E O; Joakim Palme; Stein Kuhnle; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Post-Socialist Welfare state; Social Policy; Baltic States; Eastern Europe; Sociology; Sociologi; SOCIAL SCIENCES;

   Sammanfattning : This dissertation takes a step towards providing a better understanding of post-socialist welfare state development from a theoretical as well as an empirical perspective. The overall analytical goal of this thesis has been to critically assess the development of social policies in Estonia, Latvia and Lithuania using them as illustrative examples of post-socialist welfare state development in the light of the theories, approaches and typologies that have been developed to study affluent capitalist democracies.

7. 10. Terrestrial organic carbon dynamics in Arctic coastal areas : budgets and multiple stable isotope approaches

   Författare :Vanja Alling; Christoph Humborg; Carl-Magnus Mörth; Rüdiger Stein; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic carbon; DOC; POC; multiple stable isotopes; Laptev Sea; East Siberian Sea; Lena River; Arctic; residence times; degradation; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Arctic rivers transport 31-42 Tg organic carbon (OC) each year to the Arctic Ocean, which is equal to 10% of the global riverine OC discharge. Since the Arctic Ocean only holds approximately 1% of the global ocean volume, the influence of terrestrially derived organic carbon (OCter) in the Arctic Ocean is relatively high. LÄS MER
