  1. 16. En intervjustudie om odlare av kulturspannmål i Norrland

    Kandidat-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Tilde Lindbäck; [2023]
    Nyckelord :kulturspannmål; odlare; norrländsk växtodling; småskalighet; motivation;

    Sammanfattning : En framtid med varmare klimat och mer oberäkneliga väderförändringar ställer krav på livsmedelsproduktionens anpassningsförmåga. Forskningen visar att en genetisk diversitet är viktig för att stärka resiliensen inom odlingslandskapet och stå emot framtidens utmaningar. LÄS MER

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Nsioh Elvis Nkioh; [2022]
    Nyckelord :geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

    Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER

  4. 18. 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

  5. 19. Performance Analysis of Environmentally Adaptable Grease in Large open gears

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Victor Ogunmoye; [2022]
    Nyckelord :Grease; Large open gears; tribology; lubrication; wear; friction; Twin disc; Material surface;

    Sammanfattning : Environmentally adaptable grease (EAG) lubricants are essential in applications with loss lubrication due to their biodegradable nature. This is because the lubricants could be expelled into the environment during usage in some applications e.g., marine and mining applications. LÄS MER

  7. 20. Optimization of hot strip drawing test methodology for hot forming of aluminium alloys

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Rabia Arshad; [2022]
    Nyckelord :Hot forming of aluminium; friction; high temperature lubrication; strip draw; wear.;

    Sammanfattning : The development of lightweight design for automotive applications has lasted for many years and is still increasing. Vehicles with light structures use less fuel, emit less CO2, and are better for the environment. LÄS MER
