1. Methods for the Assessment of Long-Lived Radionuclides in Humans Resulting from Nuclear Activities or Accidents - Fission track analysis of trace-amounts 239Pu and a copper hexacyanoferrate kit for monitoring radiocaesium
Sammanfattning : Fission track analysis (FTA) was developed to be applied to ultra-low levels of 239Pu in bioassay samples. An analytical protocol was established for the FTA processing. The detection limit was determined to 1.5 µBq and the calibration constant was 24 fission fragments per µBq 239Pu. LÄS MER
2. Tectonic Evolution of Taimyr in the Late Paleozoic to Mesozoic from Provenance and Thermochronological Evidence
Sammanfattning : The Taimyr Peninsula is a key element in the circum-Arctic region and represents thenorthern margin of the Siberian Craton. The Taimyr Peninsula is a late Paleozoic fold andthrust belt and preserves late Paleozoic through Mesozoic siliciclastic sedimentarysuccessions and providing an ideal location to investigate the Paleozoic to Mesozoictectonic evolution associated with the Uralian orogeny, the Siberian Trap magmatism andopening of Amerasia Basin within a circum-Arctic framework.

3. Interrogation of drug effects on the lipid composition of single cells and Drosophila brain using ToF-SIMS imaging
Sammanfattning : Lipids are essential for all living organisms on Earth. The most important function of lipids is that they act as the building blocks of cellular membranes. Lipids consist of polar head groups and non-polar tail groups and assemble into bilayer structures to create cell and organelle membranes. LÄS MER
