  1. 1. Driftoptimering av värme- och kylsystemet på Centralsjukhuset i Karlstad : Driftstrategier för perioden oktober - april

    Magister-uppsats, Karlstads universitet

    Författare :Elise Harryson; [2022]
    Nyckelord :Driftoptimering; bergvärme; geolager; värme- och kylsystem;

    Sammanfattning : De förhöjda halterna av växthusgaser i luften leder till ett varmare klimat och extremväder blir vanligare,vilket är två viktiga aspekter till att minska klimatavtrycket. Region Värmland skapade 2021 en miljöplan för att minimera klimatavtrycket, använda resurserna på ett klimatsmart sätt samt bidra till en hälsosammare miljö. LÄS MER

  3. 2. OSL dating of the Mesolithic site Nilsvikdalen 7, Bjorøy, Norway.

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Elin Jirdén; [2022]
    Nyckelord :OSL dating; luminescence; SAR protocol; water content; archaeology; Late Mesolithic; Norway.; Earth and Environmental Sciences;

    Sammanfattning : Luminescence dating is a well-established dating method within geological and archaeological research. However, the use of luminescence dating, and more specifically optically stimulated luminescence (OSL), is currently underutilised in Norwegian archaeology. LÄS MER

  4. 3. A STATISTICAL APPROACH FOR IDENTIFICATION OF CHEMICAL GROUPINGS OF ELEMENTS IN SWEDISH ROCKS WITH SPECIAL FOCUS ON ARSENIC AND SULPHUR

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Erika Frank; [2021]
    Nyckelord :Bedrock; rock type; correlation; cluster analysis; multi-dimensional scaling; individual differences scaling; discriminant analysis;

    Sammanfattning : Groundwater analyses have revealed high concentrations of the toxic element arsenic around Stockholm and Mälardalen, a problem that often is linked to high levels of arsenic in the bedrock and which could be escalated by the many construction projects in the same region. However, it is unknown what part of the bedrock is causing the contamination. LÄS MER

  5. 4. Three-dimensional modelling of the Källfallsgruvan iron oxide deposit, Riddarhyttan ore field, Bergslagen, Sweden: Integrating existing and new data to aid understanding of structural controls and mineral exploration

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Edna Spahic; [2021]
    Nyckelord :Three-dimensional modelling; Mineral exploration; Bergslagen; Riddarhyttan ore field; Källfallsgruvan iron-oxide deposit;

    Sammanfattning : The Bergslagen ore province, located in the Fennoscandian shield in the south-central part of Sweden hosts several metallic mineral deposits, one of them being the Källfallsgruvan iron-oxide deposit in the Riddarhyttan ore field, situated in a high-strain shear belt denoted as the West Bergslagen Boundary Zone (WBBZ).  An accurate 3D geological model of the Källfallsgruvan iron-oxide deposit has been generated to aid understanding of the ore body geometries and calculating volume and tonnage.

  7. 5. Feasibility of Enhanced Geothermal Systems in the Precambrian crystalline basement in SW Scania, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Hanna Kervall; [2021]
    Nyckelord :EGS; deep drilling; geothermal; petrology; petrophysical properties; Sveconorwegian; Earth and Environmental Sciences;

    Sammanfattning : The ability to evaluate the geothermal potential at a depth of five to six kilometres in the crystalline bedrock is crucial for the EGS-technology to be utilized in the future. This work focuses primarily on presenting expected geological conditions at great depths in southwestern Scania. The study is based on information from E. LÄS MER
