1. 1. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway

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

   Author : Ellen Svens; [2024]
   Keywords : Greenstone belt; IOCG; Svecokarelian orogeny; Alta-Kvænangen Tectonic Window; Bergmark anticline;

   Abstract : The Alta-Kvænangen Tectonic Window is part of a regional greenstone belt that formed around 2.3 Ga – 2.0 Ga. The Bergmark anticline in the area has gone through greenschist to amphibolite facies metamorphism and hosts Cu, Co and Au mineralizations in hydrothermal veins, albite felsite and chemical traps.

3. 2. High-Temperature Thermal Energy Storage for Innovative Hybrid CSP/PV Plants : A Comprehensive Design Optimization

   University essay from KTH/Energiteknik

   Author : Lorenzo Centonze; [2023]
   Keywords : ;

   Abstract : By means of a literature review, critical parameters in the context of thermal energy storage systems, particularly packed bed thermal energy storage systems are identified. The goals of this thesis project are to come up with an optimized design for a PBSTES and to evaluate the thermal performance of alternative storage materials derived from byproducts of industrial processes and natural rocks in order to reduce the environmental impact of the designed system.

4. 3. CO2 Sequestration by Bio-Accelerated Silicate Weathering

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Tora Uebel; Elisabeth Odelius; [2023]
   Keywords : enhanced silicate weathering; microorganisms; negative emission technology; CO2 emissions;

   Abstract : Human-caused emissions of CO2 and other greenhouse gases are an established reason for the climate changes that affect planet Earth. Negative emission technologies (NETs), for example, bio-accelerated silicate weathering bioreactors, seek to capture and store carbon from the atmosphere. READ MORE

5. 4. Future Imaginaries of Negative Emission Technologies and Folklore Myths in Icelandic Basalt: Provisional Order Emerges from the Possible Magma in the Age of ‘Hauntology’ and Broken Time

   University essay from Lunds universitet/Kulturgeografi och ekonomisk geografi; Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/Humanekologi

   Author : Rikke Jespersen; [2023]
   Keywords : NETs; Desire; Green Capitalism; Imaginaries; Storytelling; Pluriverse; Social Sciences;

   Abstract : Why do we in the Western part of world today tend to believe in technology’s mythical promises rather than in folklore myths? Imaginaries of the future influence political subjects’ actions in the present and play a key role in composing the trajectory towards the future. I have critically applied this notion to the implementation of negative emission technologies in the climate-neutrality strategy. READ MORE

6. 5. Secure log-management for an Apache Kafka-based data-streaming service

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Hjalmar Kull; Mirza Hujic; [2023]
   Keywords : Apache Kafka;

   Abstract : This thesis aims to investigate the prospect of using Apache Kafka to manage data streams based on secrecy/classification level and separate these data streams in order to meet the requirement set by the secrecy/classification levels. Basalt AB has the responsibility of managing classified data for private and state actors, including the Swedish Armed Forces and other organizations. READ MORE
