  1. 1. EN ANNAN RETORIK? Nationalistiska partiers användning av nationalistisk miljö- och klimatpolitik

    Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Edvin Sätterström; [2024-02-15]
    Nyckelord :Nationalism; suveränitet; identitet; klimatförändringar; självförsörjning; autonomi; internationalism;

    Sammanfattning : Climate change is a phenomenon that know no boundaries. While focus on environment and climate change has become highly prioritized, nationalism has spread across Europe. Nationalism is by many considered to refuse action to combat climate change although some argue that nationalism could combat global climate change. LÄS MER

  3. 2. Ageing process analysis of solar panels in graveyard geostationaryorbit for reusability potential

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Robin Drevet; [2024]
    Nyckelord :space debris; Spacecraft Materials; satellite; Space Sustainability; Space Circularity; Space Manufacturing;

    Sammanfattning : The constant growth of space debris and the associated risks force the space community to find solutions to mitigate them. Today the most advanced solutions to dispose of satellites and rocket stages after the end of mission consists of moving them either into a graveyard orbit or towards an atmospheric re-entry ending in the demise of both spacecraft and its materials.

  4. 3. The association between obesity, low-grade inflammation, self-reported knee symptoms and radiographic knee osteoarthritis in individuals with knee pain : A longitudinal cohort study

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Alma Buer; [2024]
    Nyckelord :osteoarthritis knee pain; artros knä smärta;

    Sammanfattning : Abstract  Background One of the earliest signs of knee osteoarthritis (OA) is knee pain which correlates with inflammation and disease severity. Knee OA affects 260 million worldwide, and is in similarity with obesity, characterized by ongoing low-grade inflammation. LÄS MER

  5. 4. Data analytics and machine learning for railway track degradation: Using Bothnia Line track measurements for maintenance forecasting

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Elie Roudiere; [2024]
    Nyckelord :Railway; Track geometry; Machine learning; Statistics; Predictive maintenance; Botniabanan; Järnväg; spårgeometri; maskininlärning; statistik; förebyggande underhåll; Botniabanan;

    Sammanfattning : In this paper, a statistical method is developed to improve predictive maintenance on railway track. The problem tackled is being able to predict when the next maintenance event should take place to guarantee a certain track quality class. LÄS MER

  7. 5. Thermal degradation of PFAS in solid matter

    Master-uppsats, KTH/Kemi

    Författare :Tuqa Al-Badri; [2024]
    Nyckelord :PFAS; PFOS; PFOA; thermal degradation; sewage sludge; PFAS; PFOS; PFOA; termisk nedbrytning; avloppsslam;

    Sammanfattning : Per- och Polyfluorerade alkylsubstanser (PFAS) är syntetiskt framställda organiska föreningar som har använts i stor utsträckning i konsument- och industriprodukter. PFAS-substanser besitter attraktiva egenskaper såsom resistans mot väta, fett, fläckar och är dessutom värmetåliga. LÄS MER
