1. 1. Recycling and processing of end-of-life electric and electronic equipment : fundamentals and applications

   Författare :Shunli Zhang; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Sammanfattning : This thesis presents a concept of scrapology of end-of-life electric and electronic equipment (EOL EEE) as a basis on which to develop effective recycling techniques. Various study approaches associated with this concept are detailed in this thesis. LÄS MER

3. 2. Controlled dust separation : theoretical and experimental study of the possibilities of controlled dust separation in copper producing processes

   Författare :Caisa Samuelsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Sammanfattning : Dust is generated in high temperature processes, such as incineration plants, power plants and within the metallurgical industry. The amount of dust generated, chemical and mineralogical composition of the dust as well as physical properties will largely depend on the process generating the dust but also on the off gas system used.

4. 3. Coercion and its Effects : Evidence from the Israel-Palestine Conflict

   Författare :Sophia Hatz; Håvard Hegre; Kristine Eck; Allan Dafoe; Yuri Zhukov; Uppsala universitet; []
   Nyckelord :Civil conflict; state repression; counterinsurgency; coercion; Israel-Palestine conflict; Peace and Conflict Research; Freds- och konfliktforskning;

   Sammanfattning : Counterinsurgency, state repression and other forms of coercion have multiple adverse effects. Although a state’s use of threats and force should deter an opposition group, these measures often stimulate resistance. LÄS MER

5. 4. Geometallurgical study of historical tailings from the Yxsjöberg tungsten mine in Sweden : Characterization and reprocessing options

   Författare :Jane Mulenshi; Jan Rosenkranz; Saeed Chehreh Chelgani; Pablo Brito-Parada; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Critical raw materials; Historical tailings; Tungsten; Scheelite; Geometallurgical approach; Characterization; Beneficiation; Reprocessing; Gravity separation; Magnetic separation; Flotation; Mineral Processing; Mineralteknik; Centrumbildning - Centrum för avancerad gruvteknik och metallurgi CAMM ; Centre - Centre for Advanced Mining Metallurgy CAMM ;

   Sammanfattning : 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. LÄS MER

7. 5. Unwarping and Analysing Electrophoresis Gels

   Författare :John Gustafsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Classification; Curved field lines; Gel matching; Image alignment; Image warping; Proteomics; Pulse-field gel electrophoresis; Two-dimensional electrophoresis; Variation; Yeast; Gel matching;

   Sammanfattning : Gel electrophoresis is a technology in molecular biology that is used to separate and quantify biomolecules, for example DNA and proteins. Ideally the position in a gel image corresponds to one or several properties of the molecules, such as size and net charge, but in practise the separation pattern is often warped, that is, geometrically distorted.
