  1. 1. Förutsättningar för hantering av länshållningsvatten från tunnelproduktion i byggandet av Ostlänken : Återanvändning av näringsämnen genom bevattning

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Elias Johansson; [2024]
    Nyckelord :Tunnel water; tunnel construction; nitrogen; fertilizer; irrigation; Länshållningsvatten; Tunnelvatten; Tunneldrivning; Kvävegödsel; Bevattning;

    Sammanfattning : When a tunnel is built in rock, a type of water is formed as a residual product. This tunnel wateris formed due to construction processes such as drilling requiring water and groundwater thatinfiltrates into the tunnel. The water can cause environmental damage if it is released directlyinto nature and needs to be treated. LÄS MER

  3. 2. Desalination of Archaeological Iron Objects in Vacuum

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Aleksi Pienimäki; [2023-12-13]
    Nyckelord :Archaeological iron; desalination; vacuum;

    Sammanfattning : This work investigates the efficiency of commercially available vacuum containers as a physical deoxygenation method for desalination solutions for archaeological iron. Other factors are investigated as well, such as the effect of cleaning the objects of their corrosion crusts before treatment and drying them between subsequent treatment baths. LÄS MER

  4. 3. Detecting Lithium Brine in Afghanistan Using Spaceborne Hyperspectral Data

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Torpikay Azizi; [2023-08-18]
    Nyckelord :PRISMA Hyperspectral data; lithium mineral deposits; lithium brine-rich deposits; Dashti-e- Nawar; boron deposits; Principal Component Analysis PCA ; supervised and unsupervised classification; spectral matching; spectral profile analysis; visible-near-infrared VNIR ; short-wave infrared SWIR Gypsum; Hectorite; Kaolinite; Lepidolite; lithium carbonate; lithium chloride;

    Sammanfattning : The purpose of this thesis is to utilize hyperspectral remote sensing technology for the identification and evaluation of lithium mineral deposits in Afghanistan. Afghanistan boasts unique geological formations with substantial potential for lithium resources beneath its land crust. LÄS MER

  5. 4. ANALYS OCH IDENTIFIERING AV BEKÄMPNINGSMEDEL I HISTORISKA TEXTILIER

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Stina Johansson; [2023-06-15]
    Nyckelord :XRF-analysis; FTIR-analysis; Pesticide Identification; Historical Textiles;

    Sammanfattning : This essay will investigate the risks associated with pesticide contamination in textile collections and how information about pesticide content can be found. Uniforms from the collection of the now closed Gothenburg military museum was analysed using Dosa test strips for chloride content, XRF-analysis and ATR-FTIR analysis. LÄS MER

  7. 5. Evaluating the Accuracy of Chloride Meters, The ChloroChek instrument in Sweat Testing for Cystic Fibrosis

    Kandidat-uppsats, Uppsala universitet/Institutionen för medicinsk cellbiologi

    Författare :Hawa Abshir; [2023]
    Nyckelord :Pilocarpine iontophoresis; coulometric titration; CFTR-mutations; salt consumption and sweat storage.;

    Sammanfattning : Background: Cystic fibrosis (CF) is a hereditary disorder caused by genetic mutations, which affect the chloride ion channels, leading to disrupted salt balance in different organs. A lack of properly functioning chloride ion channels can lead to formation of thick mucus, which hinders organ function, especially in the lungs where repeated inflammation occurs. LÄS MER
