   Abstract : Tungsten (W) is listed among the European Union (EU) critical raw materials (CRMs) for its supply risk and economic importance. Primarily, tungsten is produced from scheelite and wolframite mineral ores with 0.08-1.5% tungsten trioxide (WO3) grade. READ MORE

5. 3. Characterization of Chimney Flue Gas Flows : Flow Rate Measurements with Averaging Pitot Probes

   Author : Janne Paavilainen; Chris Bales; Jan-Olof Dalenbäck; Lennart Gustavsson; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flue gas; measurement; characterization; averaging Pitot tube; SolNET;

   Abstract : Performance testing methods of boilers in transient operating conditions (start, stop and combustion power modulation sequences) need the combustion rate quantified to allow for the emissions to be quantified. One way of quantifying the combustion rate of a boiler during transient operating conditions is by measuring the flue gas flow rate. READ MORE

6. 4. Recycling Inorganic Residues from Wood-based Industries to the Forest- study of Treatment Techniques and Leaching Characteristics

   Author : Maryam Mahmoudkhani; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Diffusion; Treatment techniques; Alkaline solid residues; Heterogeneous reactions; Modified column-pHstat test; Recycling; Leaching; Characterization; Field test;

   Abstract : Abstract. In order to minimize the negative impact of loss of nutrients in the forest soil (when harvesting the wood), inorganic solid residues, from wood-based industries, have to be recycled back to the forest soil. READ MORE

7. 5. Exact Minimizers in Real Interpolation : Characterization and Appliations

   Author : Japhet Niyobuhungiro; Natan Kruglyak; Irina Asekritova; Fredrik Berntsson; Froduald Minani; Luboš Pick; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The main idea of the thesis is to develop new connections between the theory of real interpolation and applications. Near and exact minimizers for E–, K– and L–functionals of the theory of real interpolation are very important in applications connected to regularization of inverse problems such as image processing.
