  1. 1. Asepticity In Dentistry Based On The Cleanliness Of Selected Test Surfaces

    Master-uppsats, Umeå universitet/Institutionen för odontologi

    Författare :Maria Yaro; Roz Lafta; [2023]
    Nyckelord :;

    Sammanfattning : ABSTRACT Background: An adequate basic hygiene routine has a significant factor in healthcare but also in dental care. This is critical during endodontic treatments that should be carried out under aseptic conditions to provide successful results. LÄS MER

  3. 2. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Yoana Ilarionova; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. LÄS MER

  4. 3. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jonas Fahlman; [2023]
    Nyckelord :astrobiology; icy moons; subglacial lakes; ice dynamics; thermal regimes; extremophiles; anthropogenic contamination; astrobiologi; ismånar; subglaciala sjöar; is-dynamik; termiska regimer; extremofiler; antropologisk kontaminering;

    Sammanfattning : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.

  5. 4. Plastic Waste to Plate : The Journey of Microplastic into Our Food System

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för design (DE)

    Författare :Krittanont Natthaporn; [2023]
    Nyckelord :Microplastic pollution; plastic contamination; in the food system; food security; human health risk; infographic; dining workshop;

    Sammanfattning : Single-use plastic packaging waste is overflowing the Earth’s surface, releasing mi- croplastics that contaminate our food. This poses serious threats and concerns to food safety and security. The project aims to raise public awareness about the issue of microplastic con- tamination in the food system. LÄS MER

  7. 5. Survival of foodborne bacteria on wooden and plastic cutting boards - A laboratory protocol

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Nicole Svärd; [2023]
    Nyckelord :foodborne bacteria; cutting board; bacterial survival; wood; plastic; laboratory protocol;

    Sammanfattning : The survival of foodborne bacteria on different cutting board materials has been studied and a functional laboratory protocol for further studies on the subject has been established. Six different bacteria, E. coli, S. aureus, L monocytogenes, S. LÄS MER
