  1. 1. 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

  3. 2. Crystallinity of Sputtered TiO2 Thin Films: a Study of the Heating and Plasma Influence on the Growth

    Master-uppsats,

    Författare :oussama ezzaher; [2023]
    Nyckelord :;

    Sammanfattning : AbstractHigh-Power Impulse Magnetron Sputtering (HIPIMS) of TiO2 thin films enhances their photocatalyticproperties compared to the films prepared by standard sputtering methods, especially when no substrateheating is employed. With no heating, the coatings present an amorphous structure that benefits from theionization of the sputtered flux granted by HiPIMS, with respect to their photocatalytic performance. LÄS MER

  4. 3. Simulation of Combustion in a Hybrid Rocket Engine

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Oscar Andersson; [2023]
    Nyckelord :Thesis; Hybrid Rocket Engine; CFD; computational fluid dynamics; combustion;

    Sammanfattning : A numerical investigation on the combustion mechanics of a hybrid rocket engine is performed through unsteady Reynolds-averaged Navier-Stokes simulation. The hybrid rocket engine model is based on an experimental laboratory scale engine design operating on GOX and HDPE as a propellant. LÄS MER

  5. 4. Mitigating Post-Harvest Losses in Bhutan through Solar Food Drying: Optimization and Analysis

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Christian Rissler; [2023]
    Nyckelord :Solar dryer; Ginger; Drying; Bhutan; Heat exchanger; Heat storage; Solar absorber; Drying rate; Air flow; Technology and Engineering;

    Sammanfattning : Bhutan is the world’s most mountainous country which comes with some logistical difficulties. Due to slow transportation times and lackluster food preservation are the post-harvest losses high which especially affects the rural parts of Bhutan negatively. LÄS MER

  7. 5. Does in vivo exposure to perfluorooctanesulfonicacid induce an altered colonic barrier function inmice?

    Kandidat-uppsats, Örebro universitet/Institutionen för medicinska vetenskaper

    Författare :Hanna-Dalia Laar; [2022]
    Nyckelord :PFOA; PFAS; Ulcerative colitis; colon barrier; gastrointestinal permeability; Ussing Chamber;

    Sammanfattning : Background: Several environmental risk factors have been implicated in the pathogenesis ofinflammatory bowel disease (IBD) and might cause an altered barrier function, a hallmark ofIBD. Recent evidence suggests that patients with late-onset ulcerative colitis (UC) have anincreased serum level of perfluoroalkyl substances (PFAS), one of the major chemical groupscontaminating our diet.
