1. 1. Svensk gruvrätt : En rättsvetenskaplig studie rörande förutsättningarna för utvinning av mineral

   Författare :Lars Bäckström; Jan Darpö; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Law Jurisprudence; Gruvrätt; mineral; utvinning; koncession; tillståndsprövning; miljöprövning; Rättsvetenskap Juridik; Law; Rättsvetenskap;

   Sammanfattning : Swedish landowners Historically, Swedish landowners have been forced to accept that that their land is claimed for mining activities. This has been done on the basis of different laws and legal rules. The Minerals Act currently in force also entitles third parties to extract miner-als from other people's property. LÄS MER

3. 2. Wise Process Routes for Varying Feedstock in Base Metal Extraction : Modelling of a Peirce-Smith Converter and Investigation of Buildup Formation in an Electric Smelting Furnace

   Författare :Andreas Lennartsson; Pekka Taskinen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Sammanfattning : Copper, like silver and gold, is one of the metals that are known to have been worked by some of the oldest civilisations on record. It is used forits unique properties such as corrosion resistance, good workability, high thermal conductivity and attractive appearance. LÄS MER

4. 3. Landfill mining approach for resource recovery from glass dumps into the circular economy

   Författare :Richard Mutafela; William Hogland; Lennart Mårtensson; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Resource recovery; landfill mining; hazardous waste; hydrometallurgical extraction; geophysical mapping; circular economy; Återvinning av resurser; gruvdrift; farligt avfall; hydrometallurgisk utvinning; geofysisk kartläggning; cirkulär ekonomi; Miljövetenskap; Environmental Science;

   Sammanfattning : Landfills and open dumps have been the most cost-effective waste disposal option, resulting in over 500,000 landfills and dumps in the EU alone. They pose significant environmental and health threats due to emission of toxic gases and release of persistent contaminants to soil and groundwater, triggering a considerable global economic impact annually.

5. 4. Efficient Map Matching and Discovery of Frequent and Dominant Movement Patterns in GPS Trajectory Data

   Författare :Can Yang; Yifang Ban; Gyözö Gidofalvi; Xiaoliang Ma; Mirco Nanni; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; map matching; contiguous sequential pattern mining; contiguous sequential pattern comparison; movement pattern detection; Kartmatchning; sammanhängande sekventiellt mönster utvinning; sammanhängande sekventiellt mönster jämförelse; rörelsemönster detektering; Geoinformatics; Geoinformatik;

   Sammanfattning : The wide deployment of Global Positioning System (GPS) sensors for movement data collection has enabled a wide range of applications in transportation and urban planning. Frequent and dominant movement patterns embedded in GPS trajectory data provide valuable knowledge including the spatial and temporal distribution of frequent routes selected by the tracked objects and the regular movement behavior in certain regions.

7. 5. The comfort of alignment: Mining, green steel, and killjoy desires in Sweden/Sápmi

   Författare :Georgia de Leeuw; Statsvetenskapliga institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; extractivism; mining; green steel; iron ore; comfort; alignment; Sweden; Sápmi;

   Sammanfattning : This dissertation deals with Swedish extractivism in Sápmi through the examples of a planned iron ore mine in Gállok/Kallak and the hydrogen-based steel transition. The main aim is to understand the trust that is placed in extraction as a means to arrive at a happy, prosperous, green future. LÄS MER
