  1. 11. Development of a Method for Separation of Adenine Nucleotides

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

    Författare :Erika Miegel; [2020]
    Nyckelord :analytical chemistry; HPLC; HILIC; chromatography; technical analytical chemistry; teknisk analytisk kemi; Chemistry; Technology and Engineering;

    Sammanfattning : Adenosine tetraphosphate, or Ap4A, is a nucleotide with very interesting proposed biological effects. Previous studies have indicated that blood glucose levels in mammals might increase in the presence of Ap4A, and that Ap4A might antagonize pancreatic ATP channels. LÄS MER

  3. 12. Principal Component Analysis for STEM-EDS images: Optimal collection parameters

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

    Författare :Isac Lazar; [2020]
    Nyckelord :Principal Component Analysis; PCA; STEM; data analysis; machine learning; metal machining; materials; materials chemistry; materialkemi; Technology and Engineering;

    Sammanfattning : STEM-EDS is a common technique used for compositional mapping in materials. The vasts amounts of raw data produced by STEM EDS is suitable for advanced analysis using methods in unsupervised machine learning. One powerful method is Principal Component Analysis (PCA) which can automatically discover significant chemical correlations in a sample. LÄS MER

  4. 13. Aqueous self-assembly behaviour alteration derived from primary structure changes of model peptides

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Marcus Bäcklund; [2020]
    Nyckelord :Model peptides; self-assembly; SAXS; FTIR; CD; physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : Understanding of the self-assembly behaviour of peptides is of great interest within several different areas such as neurodegenerative diseases, biotechnology, and peptide pharmaceuticals. In this work we have compared the impact on the self-assembly behaviour derived from systematic changes of the primary structure of A8K, where A denotes alanine and K lysine. LÄS MER

  5. 14. Mineralogical and Geochemical characterization of the Fe-Cu-Occurrence and associated Hanging wall and Footwall Alteration halo of the Viscaria D-Zone, Kiruna District, Northern Sweden

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Madelen Estholm; [2019]
    Nyckelord :Alteration halo;

    Sammanfattning : Northern Norrbotten County is one of the three major ore producing districts in Sweden. Based on the predominance of epigenetic Cu-Au and Fe-oxide mineralization this region is regarded as a typical IOCG province. The massive to layered Viscaria Cu-deposit is proposed to be a VMS deposit of Besshi-type and is unique in deposit type of the region. LÄS MER

  7. 15. Reaction Conditions Data Mining : The application of Machine Learning towards predicting the future of process development

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Samuel Hallinder; [2019]
    Nyckelord :;

    Sammanfattning : In organic chemistry and especially process chemistry, there is a constant need to develop cost-effective ways to optimize different reaction conditions. With the increased development of Machine Learning (ML) combined with Data Mining (DM) new possibilities arise to reduce time and costs in the field of chemical science. LÄS MER
