  1. 1. Method to assess machinability of engineering steels using coated carbide tools

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Petra Hedberg; [2021]
    Nyckelord :Machinability; tool wear; coated carbide; non-metallic inclusions; Ca-treated; steel; 42CrMo4;

    Sammanfattning : In this master thesis, performed at Ovako Group R&D (Hofors) a new machining test method for ranking heats of calcium-treated steels, M-Steels, has been proposed.  A total of six different heats of 42CrMo4-M steel in the quenched-and-tempered (Q+T) condition were tested.

  2. 2. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Lotte Wendt; [2021]
    Nyckelord :active layer thickness; DInSAR; subsidence; permafrost; Zackenberg; CALM; Earth and Environmental Sciences;

    Sammanfattning : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.

  3. 3. Partners in crime – How cabbage seed weevil assists brassica pod midge in damaging pods of winter oilseed rape in fields in Southern Sweden : how is insect abundance related to crop damage?

    Kandidat-uppsats, SLU/Department of Biosystems and Technology (from 130101)

    Författare :Sarah Heithausen; [2020]
    Nyckelord :monitoring; Ceutorhynchus obstrictus; Dasineura brassica; Brassica napus; Integrated Pest Management; economic threshold; pan trap; sticky trap;

    Sammanfattning : The brassica pod midge (Dasineura brassicae) has emerged as an important pest causing problems in Winter Oilseed Rape (WOSR) (Brassica napus ssp. napus) production in Southern Sweden during recent years. Adult female D. brassicae oviposit into WOSR pods. LÄS MER

  4. 4. Ett förslag för monitorering i Slutförvaret för låg och medelaktivt radioaktivt avfall

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Jesper Lindström; [2020]
    Nyckelord :SFR; Kärnbränsleförvar; Inläckage; Underjord; SKB;

    Sammanfattning : Spent Fuel Repository for low and intermediate radioactive waste, SFR, is owned by SKB (Swedish Nuclear Fuel and Waste Management Co). The repository needs more monitoring of groundwater seepage and improvement of the monitoring methods. Seepage is currently managed by a system that collects the seepage in 2 levels before pumping it to the surface. LÄS MER

  5. 5. Utvärdering av BeiDou vid statisk deformationsövervakning : En fallstudie på Gävle flygplats

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad; Högskolan i Gävle/Samhällsbyggnad

    Författare :Andreas Berglund; Alexander Breisch; [2020]
    Nyckelord :GNSS; static measurements; BeiDou; deformation monitoring; GNSS; statisk mätning; BeiDou; deformationsövervakning;

    Sammanfattning : Global Navigation Satellite System (GNSS) is nowadays a well-established and popular choice for various survey missions. Earlier studies indicate that BeiDou in combination with Global Positioning System (GPS), Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) and Galileo contributes to a lower uncertainty in 3D.
