  1. 1. 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

  3. 2. Validation of anti-cytokeratin antibodies used in rapid cancer diagnostics by isoelectric focusing and QCM technology

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Biokemi

    Författare :Reneh Kostines; [2021]
    Nyckelord :IEF; Isoelectric focusing; QCM; Attana; Cytokeratin; Keratin; Attana; Anti-cytokeratin; cancer; UBC; IDL; epithelial carcinomas; Antibody validation; Biosensor; Biosensors;

    Sammanfattning : Antibodies are Y-shaped proteins. In the human body, antibodies areproduced by plasma cells, mainly T and B cells which are included inthe adaptive immune system. The production of antibodies is stimulatedby antigens. The binding between an antigen-specific antibody and itsantigen can be like the interconnect between a lock and a key. LÄS MER

  4. 3. Converting Poultry Feather Waste into Bioplastics using Green Modifying Agents

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Marc Jirström; [2021]
    Nyckelord :polymer technology; materials science; renewable materials; Technology and Engineering;

    Sammanfattning : Handling of problematic waste material, and the use of fossil-based and non-biodegradable plastics are two major sustainability challenges. By developing solutions that convert waste material to bioplastics, it is possible to address both these issues. LÄS MER

  5. 4. Kera-Plast : Exploring the plasticization of keratin-based fibers through compression molded human hair in relation to textile design methods

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Romy Franziska Kaiser; [2020]
    Nyckelord :Compression Molding; Plasticization; Keratin Fiber; Human Hair; Textile Design Methods; Textile Thinking; Textile Activism;

    Sammanfattning : The project Kera-Plast aims to re-loop humans and nature by questioning the current systems and ethics through materiality. Human hair, currently considered as waste, functions as the base for the material exploration fabricated through thermo-compression molding. LÄS MER

  7. 5. An investigation into whether poaching creates an ecological trap for white rhinoceros in Hluhluwe-iMfolozi Park, South Africa

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Alice Michel; [2019]
    Nyckelord :ecological trap; rhinoceros; maladaptation; megaherbivore; source-sink; habitat quality; middens;

    Sammanfattning : In an ecological trap, animals choose habitat based upon cues that once led members of their species to optimal habitat, but now lead to habitat where individual fitness is reduced because of changing conditions. The southern white rhinoceros (Ceratotherium simum) is a threatened species due to poaching for its keratin horn. LÄS MER
