  1. 1. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Felix Bogdan; [2023]
    Nyckelord :Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

    Sammanfattning : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. LÄS MER

  3. 2. A Comparative Evaluation of Failover Mechanisms for Mission-critical Financial Applications in Public Clouds

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Albert Gustavsson; [2023]
    Nyckelord :Failover; Cloud computing; Cloud-native; Redundancy;

    Sammanfattning : Computer systems can fail for a vast range of reasons, and handling failures is crucial to any critical computer system. Many modern computer systems are migrating to public clouds, which provides more flexible resource consumption and in many cases reduced costs, while the migration can also require system changes due to limitations in the provided cloud environment.

  4. 3. Ammonium and nitrate sorption by biochar

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

    Författare :Yasser Alrhban; [2023]
    Nyckelord :biochar nitrogen; retention; dialysis; absorption; adsorption; ammonium; nitrate;

    Sammanfattning : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.

  5. 4. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Mehrzad Ghassemi; [2022]
    Nyckelord :Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

    Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

  7. 5. The effects of IL-4 and IL-13 on human airway smooth muscle

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Sania Merchant; [2022]
    Nyckelord :Asthma; Airway hyperresponsiveness; Airway smooth muscle cells; Calcium flux; Dupilumab; Astma; luftvägshyperreaktivitet; glatta muskelceller från luftvägarna; kalciumflöde; dupilumab;

    Sammanfattning : Typ 2-cytokiner, IL-4 och IL-13 är kända för att spela en viktig roll i airway hyperresponsiveness (AHR) eller luftvägshyperreaktivitet, där de glatta muskelcellerna (ASM) drar ihop sig för lätt och för mycket som svar på direkta eller indirekta stimuli. Detta gör AHR till en avgörande egenskap hos astmatiker. LÄS MER
