2. 11. Reprocessing historical tailings for possible remediation and recovery of critical metals and minerals : The Yxsjöberg case

   Author : Jane Mwaba Mulenshi; Jan Rosenkranz; Saeed Chehreh Chelgani; Urs Peuker; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining waste; Historical tailings; Conceptual framework; Critical raw materials; Tungsten; Scheelite; Characterization; Mineral liberation analysis; Beneficiation; Reprocessing; Mineral Processing; Mineralteknik; Centrumbildning - Centrum för avancerad gruvteknik och metallurgi CAMM ; Centre - Centre for Advanced Mining Metallurgy CAMM ;

   Abstract : With increasing consumption of primary mineral resources, the generation of mining wastes has also increased thus requiring the mining industry to address the growing environmental concerns. Waste rock and tailings are potential secondary sources of critical raw materials currently in short supply in the European Union, but also a source for environmental issues like acid mine drainage.

5. 13. Dynamic aspects of nucleocytoplasmic trafficking

   Author : Cecilia Rustum; Einar Hallberg; Urs Greber; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Cellbiologi;

   Abstract : Cellular structures and compartmentalization is the result of a dynamic steady state exchange between its components. This thesis is focused in investigations of dynamic properties of green fluorescent protein (GFP)-labeled proteins in live cells using confocal laser microscopy in combination with bleaching techniques such as fluorescence recovery after photobleaching (FRAP) and fluorescence loss in photobleaching (FLIP).
