  1. 1. Adapted data collection in field utilizing RMR and the Q-system

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

    Författare :Amanda Olsson; [2024]
    Nyckelord :Rock mass classification; Q-slope; SMR; Slope stability;

    Sammanfattning : The focus on slope stability has increased rapidly in Norway over the last years due to several unwanted landslides. In Norway, the most used method today to classify the rock mass and to determine the required reinforcement, is the Q-system. In addition to that the RMR method is also a commonly used method.

  3. 2. Structural analysis of HZO thin film and electrode using X-ray diffraction

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Elliot Winsnes; [2024]
    Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Sammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER

  4. 3. A study on the effects of mercury in the environment: A focus on atmospheric contributions

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Jonna Petersson; [2023-06-22]
    Nyckelord :Mercury; deposition; transformation; remediation; ecosystem impact; human health;

    Sammanfattning : Mercury is a metal that can transform between different forms in both the atmosphere and in ecosystems. The transformation as well as properties of the different mercury compounds affect when, how and where the effects will emerge. LÄS MER

  5. 4. Comparison of properties on Orally Disintegrating Tablets (ODTs) produced by direct compression or fluid bed granulation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Julia Ahlbom; [2023]
    Nyckelord :Orally disintegrating tablet; fluid bed granulation; disintegration time; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : Orally disintegrating tablets (ODTs) is a popular drug delivery system as they dissolve in the mouth, usually within seconds which enables easy medication for patients with problem swallowing. In this thesis properties of ODTs were compared when produced with direct compression of the excipients or the excipients were pretreated to form granules in a fluid bed granulator prior to tableting.

  7. 5. Characterization of Lamps of IRF Solar Simulator

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Mrunmayee Sonna; [2023]
    Nyckelord :IRF; Solar simulator; Characterization; Thermal simulations; Systema-Thermica; Autodesk Inventor; correlated results;

    Sammanfattning : The Swedish Institute of Space Physics (IRF) at Kiruna focuses on research activities in the ionosphere, magnetosphere, and upper atmosphere of the planet as well as the development and production of various sensors and detectors for space research. The test facility includes the IRF SpaceLab which is equipped with multiple testing equipment. LÄS MER
