Popular Abstract in Swedish Sällsynta jordartsmetaller är inte så sällsynta som namnet kan få en att tro, utan de är vanligare än t.ex. silver och guld. Till de sällsynta jordartsmetallerna hör Lantanoiderna, samt skandium och yttrium. De har många tekniska användningsområden, lasrar, permanentmagneter, lcd-skärmar, batterier, katalysatorer. De återfinns i naturen, i olika mineral, t.ex. bastnäsitThe Rare Earth Elements are a group of metals, that are of growing technical and economical importance. Current separation techniques can be detrimental to the environment, and a clean technology for separation has been devised, based on analytical chromatography of the REEs. The thesis presents column preparation and impregnation to give desired properties of the separation system, experimental a

Popular Abstract in Swedish Förmågan hos levande vävnader att läka skador är en basal faktor för överlevnad och utgör grundförutsättningen för all kirurgisk verksamhet. Det finns lokala skillnader beträffande celltyper och tidsförlopp, men mycket talar för att sårläkningsprocessen är principiellt likartad i alla vävnader. Sårläkning indelas i olika faser, varav den första utgöres av en inflammatorWound healing is a multistep process with an initial inflammatory response, followed by synthesis of extracellular matrix components and finalized by a repair phase. One main goal was to determine the impact and adhesive mechanisms of neutrophil recruitment in anastomotic healing in the colon. Passive immunization against CD18 abolished anastomotic accumulation of neutrophils, whereas no effect on

The study examines a hitherto neglected genre in Swedish poetry of the 17th and 18th centuries: the animal epitaph. From 1670 to 1760 a considerable number of such poems were composed by several of the leading poets of the day. Besides tracing the history of the genre back to its origins in the ancient Greek epigram, I am chiefly concerned with the functions that the writing of such epigrams had i

The work package (WP) 2 on Basic Exploration, Stakeholder Studies and Requirement Analysis created the scientific fundament of the project and produced essential knowledge for the conceptualisation of UrbanData2Decide. Task 2.5 brought together the previous research results and elaborated an integrated research model as well as a stakeholder requirements catalogue with first use case scenarios. In

For pulse combustors of the Helmholtz type, a heat transfer of the order two to five times higher than expected has been reported. Experiments, where the temperature profile in the tail pipe of a pulse combustor has been measured, give Ilo indication why the heat transfer should be enhanced. The interaction between the oscillating velocity field and the oscillating temperature field might explain
