  1. 6. Are European Green Bond Yields Lower Than the Yields of Their Conventional Counterparts?

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Caroline Lundberg; Olle Enelund; [2023-06-29]
    Nyckelord :Green bonds; Greenium; Sustainable investment; Principal Component Analysis PCA ; Nelson-Siegel NS ;

    Sammanfattning : In this paper, we contribute to the growing literature on sustainable finance by investigating whether European green bonds provide a lower issue yield compared to their conventional counterparts, i.e. if there exists a greenium in the primary market. LÄS MER

  3. 7. Coupling between iron and humic substances in a land-sea transitional zone in the northern Baltic Sea

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

    Författare :Anna Osterman; [2023]
    Nyckelord :Iron; Humic substances; Dissolved organic carbon; Baltic Sea; Rivers;

    Sammanfattning : In marine ecosystems around the world, iron (Fe) is a well-studied and important trace element which has been found to stimulate phytoplankton and cyanobacteria growth, as well as limit nitrogen fixation and being essential for Legionella pneumophila which is known as the main cause of Legionnaires’ disease. Fe also contributes to the brownification of freshwater and has recently been documented to increase in concentration in rivers in Sweden. LÄS MER

  4. 8. The impact of financial intermediation on economic growth in East African Community (EAC) and North African countries

    Magister-uppsats, Karlstads universitet/Handelshögskolan (from 2013)

    Författare :Ikraan Jeylani Hassan; Khali Mohamed; [2023]
    Nyckelord :EAC; North African; Financial intermediation; Economic growth; Granger causality;

    Sammanfattning : This thesis investigates the impact of financial intermediation on economic growth in two regions: the East African Community (EAC) countries (Burundi, Kenya, Tanzania, Rwanda, and Uganda) and North African countries (Algeria, Egypt, Morocco, and Tunisia). The study analyzes the regions employing a Granger causality test and explores if financial intermediation influences economic growth. LÄS MER

  5. 9. Detecting Chromatography Unit Degradation : Comparison of single- and multi-point techniques implemented in system control and monitoring software

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Max Markensten; [2023]
    Nyckelord :PCA; SOP-MPT; Fibro; chromatography; affinity A;

    Sammanfattning : Chromatography units, used in the production of pharmaceuticals, degrade with use and need to be changed or repackaged. This study investigates the effectiveness of two statistical methods, principal component analysis and simple and one-point multiparameter technique, for determining degradation in the Fibro chromatography unit.

  7. 10. Exploring Greenhouse Gas Emissions and socio-economic factors for climate change mitigation: A worldwide clustering analysis

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen; Lunds universitet/Statistiska institutionen

    Författare :Anna Pasini; [2023]
    Nyckelord :GHG emissions; Climate Change; Panel Data; Gaussian Mixture Models Cluster Analysis; PCA; Business and Economics;

    Sammanfattning : In response to the pressing need to address climate change and reduce global greenhouse gas (GHG) emissions, this study implemented Gaussian Mixture Models Clustering to detect the levels of GHG emissions and related socio-economic factors in 174 countries. To handle the panel data, Principal Component Analysis was conducted to achieve dimension reduction. LÄS MER
