  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

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Laszlo Zorc; [2023-08-18]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. The effect of dividend policy and financial performance on the P/E ratio : A study to investigate the ef ect of dividend and financial ratios on the P/E ratio of stocksin the Swedish stock market

    University essay from Umeå universitet/Handelshögskolan vid Umeå universitet

    Author : Samara Sharin; [2023]
    Keywords : Finance; Stock Market; Swedish stock market;

    Abstract : This master's thesis investigates the connection between profit margin, return on assets, long-term debt, and price-to-earnings (P/E) ratio and they relate to dividend. The study examines whether companies with increasing dividends and companies with decreasing and constant dividends have significantly different effects on the P/E ratio. READ MORE

  4. 3. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach

    University essay from Lunds universitet/Geologiska institutionen

    Author : Elsa Muller; [2023]
    Keywords : Acidification; Warming; Deoxygenation; Foraminifera; Ammonia confertitesta T6 ; Culture Experiment; Trace elements; Earth and Environmental Sciences;

    Abstract : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. READ MORE

  5. 4. Optimization of Material Cost and Carbon Footprint of Flat Reinforced Concrete Slabs with Simple Steel Piles : Designed according to Eurocode and Swedish appendix EKS

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Oskar Lönn; [2023]
    Keywords : Optimization; RC slab; Material cost; API;

    Abstract : When designing reinforced concrete (RC) slabs with steel piles various variables must be considered, from the internal force to the distance of piles. An endless number of designs are possible, leaving space for optimizing designs. READ MORE

  6. 5. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Ann-Kathrin Wild; [2022]
    Keywords : trace elements; tree-rings; dendrochemistry; dendroclimatology; ITRAX; Laacher See; mofettes; tree-bark; Quercus sp.; Fagus sp.;

    Abstract : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.
