  1. 1. Comparison of preconditions for tooth sample collection and compositional change over time

    Master-uppsats, Umeå universitet/Institutionen för odontologi

    Författare :Sara Azadian; Lovisa Persson; [2022]
    Nyckelord :Dental plaque; bacteria; composition;

    Sammanfattning : Background The mouth can be colonized by many bacterial species that are associated with both health and disease. Bacteria analyses are an important part of diagnosing and treating dental diseases, but there is no consensus regarding which sampling method to use for these analyses. LÄS MER

  3. 2. Developing complementary supercritical fluid chromatographic methods for a high throughput purification process

    Master-uppsats, Karlstads universitet

    Författare :Alma Söderström; [2022]
    Nyckelord :Supercritical Fluid Chromatography; Pharmaceutical Industry; Column screening; Green chemistry; Superkritisk vätskekromotografi; Läkemedelsindustri; Kolonn set; Grön kemi;

    Sammanfattning : Supercritical fluid chromatography (SFC) is an expanding chromatographic technique that is part of the evolving field of green chemistry due to its short run times and use of non-toxic solvents in combination with recycled CO2. The use of a suitable column is essential for separation science in general and there is a wide variety of SFC compatible columns available on the market. LÄS MER

  4. 3. A comparison of different machine learning algorithms applied to hyperspectral data analysis

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Axel Vikström; [2021]
    Nyckelord :;

    Sammanfattning : Hyperspectral image analysis works with image data where each pixel contains hundreds of wavelengths acquired from spectral measurements. It is a growing field of research in the sciences and industries because it can distinguish visually similar objects. LÄS MER

  5. 4. Multivariat dataanalys och gisutvärdering av metallsammansättningen i jord

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Julie Sandberg; [2021]
    Nyckelord :;

    Sammanfattning : This report was made to evaluate the multivariate data analysis as a tool to investigate the metal composition of soil with the use of principal component analysis (PCA), and in combination with GIS interpolation. Data with several variables and observations can be difficult to analyze with only descriptive diagrams. LÄS MER

  7. 5. Improved prediction of biogas production at Uddebo wastewater treatment plant : Substrate modelling in SIMCA

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Isak Gullman; [2021]
    Nyckelord :Anaerobic digestion; Biogas; Industrial waste; Modelling; Sewage sludge;

    Sammanfattning : Anaerobic digestion is a complex process, dependent on multiple factors, which can be made more stable and efficient with the help of process models. A more stable process could reduce biogas torching, which increases the amount of renewable energy available for heat- and electricity production and vehicle fuel. LÄS MER
