  1. 6. Multidisciplinary perspectives on a natural attenuation zone in a PCE-contaminated aquifer

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Robin Jansson; [2018]
    Nyckelord :DCIP; groundwater chemistry; Tetrachlorethene; PCE; natural attenuation; Earth and Environmental Sciences;

    Sammanfattning : The old dry-cleaner in Hagfors, is one of the most seriously tetrachloroethene (PCE) contaminated sites in Sweden. Ever since the pollution was discovered in the groundwater in the 1990s, the site has undergone remedi-ation two times with limited success. LÄS MER

  3. 7. Comparison of Photogrammetry Interpretation with Physical Structural Field Measurements

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Fredrik Osterman; [2017]
    Nyckelord :Fracture mapping; photogrammetry; 3D-modelling; rock classification; field safety; Sprickkartering; fotogrammetri; 3D-modellering; bergklassificering; säkerhet i fält;

    Sammanfattning : Fracture mapping of bedrock and knowledge about how fractures influence rock strength and stability is of great importance in a constructional context. These factors largely dictate where one can build and not build in rock, and to what extent reinforcements and safety measurements are needed. LÄS MER

  4. 8. Undersökning av brottytor på utmattningsprovstavar av stål till borrkronor

    Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Mathias Eriksson; [2016]
    Nyckelord :fatigue failures; fracture surface; non-metallic inclusions; scanning electron microscopy; utmattningsbrott; brottytor; icke-metalliska inneslutningar; svepelektronmikroskop;

    Sammanfattning : Utmattningsbrott är ett återkommande problem som uppstår i borrkronor. Atlas Copco Secoroc har tidigare gjort utmattningsprovningar på fyra serier provstavar. Serierna skiljer sig från varandra på så sätt att stålet är hårt respektive mjukt härdat. Det hårdhärdade stålet är indelat i två serier. LÄS MER

  5. 9. Significance of Fracture Patterns in a Rock Mass during Excavation by Blasting in Bandhagen, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Mattias Ryttberg; [2015]
    Nyckelord :Fracture sets; rock excavation; rock wall; instability; Spricksystem; utschaktning; bergvägg; instabilitet;

    Sammanfattning : When excavating a rock wall by blasting, pre-existing structures in the rock has a strong impact on the stability of the wall. For excavation in Bandhagen in Stockholm, the nature and orientation of the pre-existing geological features, namely fractures, were not taken into consideration before excavation begun. LÄS MER

  7. 10. Wear characterization and wear mapping of a coated cutting tool : Development of cutting tool test fixture and wear testing

    Master-uppsats, Karlstads universitet/Science, Mathematics and Engineering Education Research (SMEER)

    Författare :Abdulbaset Mussa; [2015]
    Nyckelord :tribology; friction; sliding wear; coating;

    Sammanfattning : Wear mechanisms of the cutting tools are well investigated worldwide. Usually researchers use the cutting process itself, turning by single point cutting, as their investigation method, which includes turning a metal cylinder with a pre-selected work-material and predetermined cutting conditions.
