  1. 11. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Edvin Nilsagård; Rebecka Knutsson; [2022]
    Nyckelord :ert; jet grouting; quality control; pygimli; res2dinv; resistivity; Technology and Engineering;

    Sammanfattning : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. LÄS MER

  3. 12. Trace element leaching from alum shale fines and red ash from Kvarntorp during a large column test

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Helena Rydfjord; [2022]
    Nyckelord :Alum shale; Leachate; Trace elements; Kvarntorp;

    Sammanfattning : Fuel shortage during the Second World War led to oil production in Kvarntorp, Kumla during 1942-1966 by pyrolyzing alum shale rich in pyrite, FeS2, and organic material such as kerogen. This production has led to a lot of waste laying deposited out in the open after the mining closed and has had negative environmental impact in the form of ongoing weathering and leaching of acidic water and leaching of trace elements into its surroundings.

  4. 13. A study of the adsorption isotherms of Ion-pair reagents

    Kandidat-uppsats, Karlstads universitet

    Författare :Mehmet Bilici; [2022]
    Nyckelord :Tributylamine; adsorption isotherm; liquid-liquid extraction; gas chromatography;

    Sammanfattning : In this project, the optimization of obtaining adsorption isotherms for the ion pair reagent, tributylamine was tested. The goal was to have a better understanding of the chromatographic process when separating biomolecules, such as oligonucleotides. LÄS MER

  5. 14. Termochip för hästar : jämförelse med rektal temperatur och beteende vid mätning

    Uppsats för yrkesexamina på grundnivå, SLU/Dept. of Clinical Sciences

    Författare :My Monto Zale; [2022]
    Nyckelord :beteende; chip; häst; häst-; microchip; sensor; temperatur; termochip;

    Sammanfattning : Temperaturmätning är vanligt förekommande inom djursjukvård för att ge en indikation på djurets hälsostatus. Vanligt är att temperaturen mäts rektalt men detta accepteras inte av alla patienter. LÄS MER

  7. 15. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Stéphanie Nyström; [2022]
    Nyckelord :Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Sammanfattning : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).
