  1. 1. APPLICATION OF IN SITU Rb-Sr DATING AND GEOCHEMICAL INVESTIGATIONS ON A NEW, 1.52-1.56 GA. OLD PEGMATITE FIELD IN THE ARCHIPELAGO OFF GOTHENBURG, IDEFJORDEN TERRANE, WESTERN SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Laszlo Zorc; [2023-08-18]
    Nyckelord :;

    Sammanfattning : In this study, Rb-Sr geochronology was used to determine the crystallization/cooling ages of muscovites and biotites from mapped primitive barren and rare element pegmatites in the Stora-Le-Marstrand Formation in the southwestern archipelago of Gothenburg. The results indicate that primitive barrens can be linked to the DG2 deformation event that occurred 1. LÄS MER

  3. 2. Kernel Methods for Regression

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

    Författare :Tom Lennart Rossmann; [2023]
    Nyckelord :Kernel Methods; Regression; Ridge Regression;

    Sammanfattning : Kernel methods are a well-studied approach for addressing regression problems by implicitly mapping input variables into possibly infinite-dimensional feature spaces, particularly in cases where standard linear regression fails to capture non-linear relationships in data. Therefore, the choice between standard linear regression and kernel regression can be seen as a tradeoff between constraints on the number of features and the number of training samples. LÄS MER

  4. 3. Policing in a small society : The 'closely-knit' and underresearched Faroe Islands

    Master-uppsats, Malmö universitet/Institutionen för kriminologi (KR)

    Författare :Ingmar Berg Mikkelsen; [2023]
    Nyckelord :closely-knit; Faroese; Faroe Islands; Føroyar; Nils Christie; policing; small societies; Faroese; Faroe Islands; Føroyar; løgregla; Nils Christie; oyggjasamfelag; police; sambond; samfelag; smá samfeløg; smátjóðir; tætt knýtt;

    Sammanfattning : The Faroes are a rural, ’closely-knit’ (Nils Christie 1982), and unexplored society. Hardly anyone is a stranger. Neither are police officers and offenders. How does this affect policing? Based on 6 interviews with Faroese police officers and 3interviews with Faroese offenders, the ’living law’ (i. LÄS MER

  5. 4. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Ismail Yussuf Hassan; [2023]
    Nyckelord :graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

    Sammanfattning : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

  7. 5. What is it really like? - Mental illness among the Sámi : -

    Kandidat-uppsats, Umeå universitet/Institutionen för omvårdnad

    Författare :Amanda Digan; Aana Edmondson; [2023]
    Nyckelord :Culture; Mental Illness; Sámi; Indigenous; Kultuvrra; sielulasj dávdda; sábme; álggoálmmuk; Kultur; Psykisk ohälsa; Same; Urfolk;

    Sammanfattning : Background: Mental illness is a problem in today's society. Research shows that indigenous people are more at risk for mental health problems than their non-indigenous peers. Discrimination can affect individuals' self-image and mental health. Research shows that healthcare professionals lack cultural understanding for ethnic minorities. LÄS MER
