  1. 1. FRÅN VITT TILL GRÖNT, RÖTT ELLER BRUNT: Kan blindering åtgärdas med kunskap vi redan har?

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Annica Drotz; [2023-11-07]
    Nyckelord :blanching; oil paint; bloom; paint layer; accelerated aging; consolidation;

    Sammanfattning : Blanching is a common phenomenon affecting the binding medium within the paint, resulting in an abnormality of the paints light scattering. Multiple studies have confirmed that the change is the result of pore formation within the binding medium caused by humidity or water damage. LÄS MER

  3. 2. Water purification of ibuprofen using whey protein aerogels with and without PNF-structure

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jessica Lyrner Morén; David Jonsson; [2023]
    Nyckelord :Aerogels; water purification; ibuprofen; protein nanofibrils PNF ; whey protein; attitudes; scientific research; Aerogeler; vattenrening; ibuprofen; protein nanofibriller PNF ; vassleprotein; attityder; naturvetenskaplig forskning;

    Sammanfattning : Clean water, free from pharmaceuticals, is important both for land and water living animals. Protein nanofibrils (PNFs) have already been shown to be a promising candidate for water purification of pharmaceuticals but there is a lack of research that compares PNF materials to non-PNF protein materials for water purification.

  4. 3. Biocatalysis in Pickering emulsions

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Christine Vera Isabel Schmidt; [2023]
    Nyckelord :Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Sammanfattning : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. LÄS MER

  5. 4. Evaluation of antimycobacterial molecules' capacity to kill mycobacteria and their toxic effect on human cells.

    Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Filippa Henriksson; [2023]
    Nyckelord :Drug evaluation; In vitro; Mycobacterium tuberculosis complex; REMA; Tuberculosis; In vitro; Mycobacterium tuberculosis complex; REMA; tuberkulos; utvärdering av läkemedel;

    Sammanfattning : Tuberculosis is a fatal airborne disease caused by bacteria from the Mycobacterium tuberculosis complex (MTBC). The incidence of contracting tuberculosis is estimated to be around 10.6 million cases each year. Increased drug resistance among mycobacteria has led to the need to develop new treatments. LÄS MER

  7. 5. Synergies of nutrient fractions for fertilization in agriculture

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Linda Adjei; [2022]
    Nyckelord :Phosphorus; Wastewater; Polonite; molybdenum blue spectrophotometry; Fertilizer; Sunflower; Plant growth;

    Sammanfattning : A few countries are controlling the worlds phosphate reserves and this raw material is depleting at a faster rate. Most of the mined phosphate rock comes from Morocco and the Russia area which has unstable security. Studies shows that about 40% of potash export and 28% of nitrogen and phosphorus (P) fertilizer products comes from the Russia area. LÄS MER
