  1. 1. Extracting versatility : Films commissioned by the mining industry in postwar Sweden

    Författare :Ole Johnny Fossås; Marina Dahlquist; Bo Florin; Zoë Druick; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; film history; swedish film; sponsored film; industrial film; useful cinema; mining; Sápmi; non-theatrical film; public service television; film distribution; the Swedish Film Institute; Radio Sweden; documentary film; film policy; filmhistoria; beställningsfilm; svensk film; industrifilm; informationsfilm; Sápmi; gruvindustrin; Svenska Filminstitutet; Sveriges Radio; Cinema Studies; filmvetenskap;

    Sammanfattning : This study investigates how films commissioned by Swedish mining companies were employed for institutional use between 1945 and 1965. A central aspect of what gave these films their versatility stems from circumstances that allowed commissioned texts to pass as non-partisan audiovisual aids, as educational and informative instruments and as occasional examples of film art through intermediaries.

  3. 2. Biogeochemical Processes in Denitrifying Woodchip Bioreactors and their Application in the Mining Industry

    Författare :Albin Nordström; Roger Herbert; Fritjof Fagerlund; Gunno Renman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water treatment; mine drainage; nitrate; nitrous oxide; DNRA; fermentation; syntrophy; temperature; kväverening; gruvvatten; nitrat; lustgas; DNRA; fermentation; syntrofi; temperatur; Hydrology; Hydrologi;

    Sammanfattning : This thesis evaluates passive denitrifying woodchip bioreactors (DWBs) for the removal of nitrate (NO3-) in neutral pH mine drainage, where water is passed through a carbon-rich porous matrix (e.g. woodchips) for the reduction of NO3- to nitrogen gas. LÄS MER

  4. 3. Corporate Social Responsibility practice in the mining industry

    Författare :Helena Ranängen; Annik Magerholm Fet; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental Management; Miljöledning;

    Sammanfattning : Corporate Social Responsibility (CSR) has frequently been discussed throughout the years. However, in the 1990s criticism of multinational companies and their production in developing countries resulted in new and more demanding requirements from society. LÄS MER

  5. 4. Short-term Underground Mine Scheduling : An Industrial Application of Constraint Programming

    Författare :Max Åstrand; Mikael Johansson; Mats Carlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduling; mining; underground mines; constraint programming; large neighborhood search; korttidsplanering; gruvdrift; underjordsgruvor; villkorsprogrammering; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The mining industry is facing a surge in automation in the pursuit of safe and profitable operations. As the excavation process is increasingly automated, today's mining companies seek to optimize the coordination of the now automated mining activities. LÄS MER

  7. 5. On deoxidation practice and grain size of austenitic manganese steel

    Författare :Dimitrios Siafakas; Anders Jarfors; Taishi Matsushita; Johan Nils Ahlström; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hadfield steel; deoxidation; grain size; inoculation; particles; carbides; oxides; Hadfield stål; desoxidering; kornstorlek; ympning; partiklar; karbider; oxider;

    Sammanfattning : The exceptional wear resistance and work hardenability, place Hadfield steel as one of themost important materials for manufacturing cast components used in the mining, crashing,drilling, and excavation industries. In all metallic alloys used for component casting, themechanical properties are highly influenced by the microstructure of the material. LÄS MER
