  1. 21. Assessment of static performance of LKAB´s welded mesh : Laboratory testing and analysis

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

    Författare :Fredrik Eriksson; [2020]
    Nyckelord :;

    Sammanfattning : Surface support is an areal support, which is installed on rock excavation surface to prevent bulking of rock mass and retain loose rock fragments. Welded wire mesh is one type of surface support. Literature study indicates that there is a wide range of testing methods on mesh. LÄS MER

  3. 22. Monte Carlo Simulations of Bowing Effects Using Realistic Fuel Data in Nuclear Fuel Assemblies

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

    Författare :Marcus Westlund; [2019]
    Nyckelord :bowing effects; fuel assembly perturbations; nuclear; serpent; monte carlo;

    Sammanfattning : Deformations of nuclear fuel assemblies have been observed in nuclear power plants since the mid-90s. Such deformations are generally called bowing effects. LÄS MER

    Sammanfattning : A well-functioning transport system that can ensure efficient distribution is an important part of a mass-producing company. This is also the case for Holmen Paper Braviken, a paper mill with a widespread market base. LÄS MER

  5. 24. Throughflow Study on Bleeding for Part Load Compressor Operation

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Simon Hedkvist; [2019]
    Nyckelord :Compressor; Minimum environmental load; Aerodynamic; Throughflow; Stability; Bleeding;

    Sammanfattning : The transition of the European energy grid to renewable energy sources is increasing the demand for back-up capacity with high flexibility. Current fossil fuel plants are continuously being forced into part load operation, where they are limited by pollution regulations that dictate their minimum environmental load, MEL. LÄS MER

  7. 25. Carbonaceous aerosols and trace metal deposition in high-latitude snow : a comparative study in Sweden and Alaska

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

    Författare :Anika Pinzner; [2019]
    Nyckelord :PM; carbon particles; pXRF; arctic; subarctic; EC OC; LAHM; PSAP; TOT; ICP-MS; filter; contamination; albedo;

    Sammanfattning : This study investigates the advantages and disadvantages of several destructive and non-destructive analytical methods that can be employed to characterize airborne par-ticulate matter (PM) deposited in seasonal snow. To this end, a comparative study was conducted on PM obtained from snowpack surveys in two Arctic/subarctic regions of Northern Sweden and Interior Alaska, USA. LÄS MER
