  1. 1. Weaponizing Ambiguity : How do nationalist political attitudes in pre-election periods influence anti-immigrant voting  in the MENA region?

    Kandidat-uppsats, Uppsala universitet/Institutionen för freds- och konfliktforskning

    Författare :Cécile Landiech; [2024]
    Nyckelord :nationalism; anti-immigration; Middle East; North Africa; Kais Saied; Recep Tayyip Erdogan;

    Sammanfattning : This research paper explores the effect of nationalist attitudes on anti-immigrant voting, focusing on the securitisation of migrants and its influence on anti-immigrant sentiments as a causal mechanism. Previous research indicates a correlation between shock events such as a vast influx of migrants and the perception of competition as precursors to anti-immigrant voting. LÄS MER

  3. 2. Microbial production of chemical building blocks from lignin

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Kevin Bertilsson; [2024]
    Nyckelord :Lignin; Green plastic; Vanillin; Microbial production; Applied microbiology; Biology and Life Sciences;

    Sammanfattning : Plastics, derived from fossil fuels, have raised considerable environmental concerns. This has prompted the search for sustainable and safer plastic precursors alternatives. One alternative explored in the present study is vanillin, a phenolic compound derived from lignin, an abundant and renewable natural polymer. LÄS MER

  4. 3. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Sofia Westberg; [2023]
    Nyckelord :Carbon fiber; lignin; cellulose; continuous conversion;

    Sammanfattning : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. LÄS MER

  5. 4. Yearly distribution and composition of per- and polyfluoroalkyl substances (PFAS) in Luleå wastewater treatment plant

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

    Författare :Moa Sjöberg; [2023]
    Nyckelord :PFAS; WWTP; Wastewater treatment; Consumer products; Precursors;

    Sammanfattning : PFAS (per- and polyfluoroalkyl substances) are a large group of substances that are used in a large variety of products because of their unique water and dirt repellent properties. The substances are extremely persistent and can spread over large distances in groundwater, surface water, and in the air, which makes them an environmental and a health concern. LÄS MER

  7. 5. PAMPaR: Parallel Analysis of miRNAs, Proteins and RNAs. Dynamic Profiles of miRNAs, mRNAs and Specific Proteins in Mouse Embryonic Stem Cells Differentiating into Neural Precursors

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Amelie Carlström; [2023]
    Nyckelord :PAMPaR; SPARC; Proximity extension assay; Neuronal differentiation; Mouse embryonic stem cells; PAMPaR; SPARC; Proximity extension assay; Neuronal differentiering; embryonala musstamceller;

    Sammanfattning : MikroRNA-molekyler (miRNA) är viktiga icke-kodande RNA-molekyler för post-transkriptionell reglering av proteinkodande gener. De har även effekter på många cellulära processer såsom differentiering. De biosyntetiska reaktioner som skapar miRNA involverar proteiner som själva regleras av miRNA. LÄS MER
