  1. 1. A PILOT STUDY ON STAIN REDUCTION Effects of Stains, Cleaning Agents, and Cleaning Methods on Polyester Textiles

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Karin Hindborg; [2023-08-28]
    Nyckelord :colour measurements; spot cleaning; suction table; tensile testing; textile con-servation;

    Sammanfattning : The thesis was an experimental pilot study that investigated efficiency and effects of stains and cleaning agents on polyester textiles. A literature review and interviews with textile conservators were used to understand the degradation of polyester fibres and to find suit-able staining and cleaning agents to use in the experiments of the study.

  3. 2. Permeation studies of Niacinamide and its effect on human skin

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

    Författare :Andebrhan Fsahaye; [2023]
    Nyckelord :niacinamide; permeation; human skin; impedance; hydration;

    Sammanfattning :  Background: Niacinamide (NIA) is one of the most commonly used cosmetic ingredients. It belongs to the vitamin-B3 family and has extensive dermatological therapeutic benefits. NIA has been proven to be a useful skincare product in serving as anti-acne agent, preventing skin hyperpigmentation, removal of wrinkles from the face etc. LÄS MER

  4. 3. Antimicrobial drug residues in milk : effect on mesophilic starter cultures

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Frida Willdén; [2022]
    Nyckelord :mesophilic starter cultures; lactic acid bacteria; aroma producing bacteria; acid producing bacteria; penicillin G; oxytetracycline; trimethoprim; sulfadiazine;

    Sammanfattning : Starter cultures have an essential role in cheese production contributing to desired acid production and formation of aroma- and flavour compounds during cheese maturation. Residues of antimicrobial drugs might reduce the activity of dairy starter cultures and subsequently cause impaired cheese quality. LÄS MER

  5. 4. Bio-enhanced silicate weathering : Coupled to sequestration of CO2

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Limnologi

    Författare :Marcus Westholm; [2022]
    Nyckelord :NETs; Bio-enhanced weathering; Carbon capture;

    Sammanfattning : Weathering of silicate minerals has long been a known source of natural CO2 sequestration, that could be increased in the presence of microorganisms. Bio-enhanced weathering of silicate minerals could increase the sequestration of CO2 from the atmosphere. LÄS MER

  7. 5. RNAlater som bevaringsmetod för muskelvävnad : En jämförande metodstudie om frystorkning, RNAlater och RNAlater-ICE som bevaring av skelettmuskulatur inför molekylärbiologiska analyser

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Alice Engvall; Tuva Eriksson-Viklund; [2022]
    Nyckelord :RNAlater; RNAlater-ICE; frystorkning; bevaringsmetod; skelettmuskulatur; muskelfibrer; protein; Western Blot; proteinbestämning; glykogenmängd; enzymaktivitet; molekylärbiologi;

    Sammanfattning : I denna metodstudie jämfördes Thermo Fishers bevarande lösningar RNAlater och RNAlater-ICE med frystorkning som bevaring av skelettmuskulatur från människa. Studien gjordes med syftet att avgöra om RNAlater och/eller RNAlater-ICE kan ersätta frystorkning, i hopp om att underlätta dissekering av muskelvävnad. LÄS MER
